STABILIZER FOOT MECHANISM FOR CONSTRUCTION EQUIPMENTS The Related Art
The invention relates to the foot mechanisms, which are first placed on the ground by being opened with the help of a hydraulic cylinder and then lift the rear wheels of the equipment in order to ensure stabilization of construction equipments called as backhoe-loader during excavation.
The invention relates to the stabilizer mechanism, which provides stabilization of construction equipment during the excavation operation of construction equipments, and which is adapted to the equipment, and it comprises a chassis, which is fixed at the construction equipment, and which has a positioning space wherein the cylinder is placed, a middle articulation component connected with the said chassis in a way that it would make angular motion, and lower foot articulation, which is fixed at the said middle articulation component in a way that it would make angular motion when found in vertical foot position and it would not move when found in outwardly extending foot position.
Background of the Invention
In the construction equipments, the foot mechanisms, which prevent the excavating machine from losing its balance during the excavation period, and which ensure its balance on the ground, are positioned at the rear part of the machine.
Said foot mechanisms are structures, which are driven by hydraulic system and fixed on the machine body, and which are opened and closed via the cylinders through hydraulic control system. Two types of mechanisms are found in the prior art. One of these is the vertical foot mechanism pressing on the ground perpendicularly via opening of the cylinder that is connected to the inner box section among the two nested box sections. The other one is the outwardly extending foot mechanism pressing on the ground via opening of the cylinder, one end of which is fixed at the chassis, while its other end is fixed at the lower part of the foot.
In the USA patent with no US3630544 and title: "Stabilizer For Earthmoving Machinery"; a structure is disclosed, which is the mechanism called outwardly extending foot, and it is used in excavation operations in wide areas where there are no area limitations.
In the USA patent with no US4236643 and title: "Vehicle Stabilizer Assembly"; an arm supported on the machine body in a way that it would make angular motion and foot connected with this arm and a hydraulic cylinder providing opening and closing motion to both of these parts are disclosed.
In the USA patent with no US4286803, date 02.10.1978, and title: "Stabilizer Assembly"; again an outwardly extending foot mechanism fixed on the construction equipment body in a movable manner is disclosed.
Although the above said outwardly extending foot mechanism construction equipments are more stable than the vertical foot mechanism structures, as it would be seen in the said patents, these types of feet are inefficient in working narrow areas. This is because, the outwardly extending foot structures are left outside the width of the wheels when pressed on the ground and when looked from the front or the back.
The USA patent with no US6607347 and title "Backhoe Stabilizing Leg" is one of the examples having vertical foot system. Machines having vertical foot system have less balanced structure than the outwardly extending foot system machines. This is because; the feet remain within the outmost limit of the wheels when looked at the machine from the front or the back. There are two patents wherein both the outwardly extending foot and the vertical foot systems are combined. The first one of these is the USA patent with no US2005/0262741 A1 and title "Variable Position Stabilizer Leg". The system found in the said patent implements the same operation with two cylinders for each foot. An extra cylinder makes the system heavier and increases the cost. Due to the same reason, the operating speed of the system decreases. Mounting of hydraulic systems are more difficult than mechanical systems, because further mounting of pipes and hoses are required for the hydraulic system. Controlling the system described in the patent becomes more difficult while working in the outwardly extending foot position, because the operator has to control the two individual cylinders at the same time. Maintenance costs and the risk of failure of such a system is more than a mechanical system. The second one is the USA patent with no US6443490 B2 and title "Dual Mode Stabilizer for Backhoe-Loaders and Backhoe Attachments". The pieces of this system are much more complex and thus difficult to produce than the "dual mode stabilizer foot" system of the present invention. Since the mechanism found in the said patent is made via a sliding system, it requires sensitive production and has the possibility of encountering wearing problems. Mounting of the mechanism is also difficult in this system due to the complexity of the pieces. As it is told in the patent, in order to provide problem-free operation of the system in the outwardly extending foot position, the pin has to enter in the lock without clearance. This situation requires sensitive production and thus leads to increase of cost like the one in the sliding system. Moreover, wearing of this connection would affect problem-free operation of the system in time. Two separate bases are found in the system of the patent for the outwardly extending foot and the vertical foot; however, in the dual mode feet system, both of the foot positions can be obtained by a single base. Due to having a lot of mounting pieces and due to the production difficulties caused by complex pieces, the service life of the said system is short.
Description of the Invention Purpose of the invention is to have different technical properties bringing a novel expansion in the related field with regard to the applications used in the prior art.
Purpose of the invention is to have both the outwardly extending foot and the vertical foot mechanisms in the same machine and provide the operator with the facility to go into vertical foot position while making excavation in narrow areas and implement excavation operation in outwardly extending foot position in a more stabile way while working in wide areas.
Purpose of the invention is to use box sections in dual mode foot system and take measures against twisting. Due to the same reason, the dual feet system has a stronger structure in terms of durability.
Purpose of the invention is to ensure both the outwardly extending foot and the vertical foot positions with a single base in the dual mode foot system. By only changing a pin, transition between the two systems is easily obtained via the dual mode foot system. Since the dual mode foot mechanism is more stable in the outwardly extending foot position, it provides more comfortable excavation for operators.
Purpose of the invention is to have lower maintenance costs, since the dual mode foot system has a less complex structure and the attachment performance is increased in accordance with the stabilizer foot properties.
Purpose of the invention is to provide the dual mode foot mechanism with another significant advantage. While the dual mode foot system is found in either one of the foot positions and when the cylinder is completely closed for getting into driving position, the feet remain within the width of the wheels when the backhoe-loader is seen from the front or the back. This is a quite important detail, since this feature is absolutely required in order to prevent the backhoe- loader from hitting the structures found around while going through narrow areas.
Purpose of the invention is to bring the machine in a hydraulically more stabile state via the dual mode foot system having a wider cylinder than the present vertical foot and outwardly extending foot cylinders.
In order to achieve the above said purposes, the present invention relates to the stabilizer mechanism, which provides stabilization of construction equipment during the excavation operation of construction equipments, and which is adapted to the equipment, and it comprises a chassis, which is fixed at the construction equipment, and which has a positioning space wherein the cylinder is placed, a middle articulation component connected with the said chassis in a way that it would make angular motion, and lower foot articulation, which is fixed at the said middle articulation component in a way that it would make angular motion when found in vertical foot position and it would not move when found in outwardly extending foot position.

Detailed Description of the Invention
The invention relates to the stabilizer mechanism (100), which provides stabilization of construction equipment during the excavation operation of construction equipments, and which is adapted to the equipment, and it comprises a chassis (10), which is fixed at the construction equipment, and which has a positioning space (14) wherein the cylinder (20) is placed, a middle articulation component (30) connected with the said chassis (10) in a way that it would make angular motion, and lower foot articulation (40), which is fixed at the said middle articulation component (30) in a way that it would make angular motion when found in vertical foot position and it would not move when found in outwardly extending foot position.
The present invention comprises at least one intermediate bearing component (70), which is positioned between the said middle articulation component (30) and the lower foot articulation (40), and on which pin holes (71 , 72, 73) are formed; right and left links (50, 60) connected between the said intermediate bearing component (70) and the chassis (10); holes (11 , 12, 13) formed on the said chassis (10); holes (31 , 32, 33, 34) for providing connection of the chassis (10), the cylinder (20), and the lower foot articulation (40) with the said middle articulation component (30); on the said lower foot articulation (40), intermediate bearing component (70) and holes (41 , 42) for providing fixation of the lower foot articulation (40) in vertical foot position in a way that it would move parallel to the chassis (10); a base (80) positioned at a region of the said lower foot articulation (40) that is close to the ground and a mode pin (90) providing its connection with the intermediate bearing component (70); and holes (21 , 22) providing connection of the said cylinder (20) with the chassis (10) and the middle articulation component (30).
The way of operation of the stabilizer mechanism (100) is as follows: It is adapted to the construction equipment with the help of the chassis (10). While the chassis (10) fixes the cylinder (20) via the upper hole (11 ), it also provides an operating medium of the cylinder (20) via the positioning space (14). After connection of the cylinder (20) with the chassis (10) with the help of the fixation pin (91 ) found at the chassis upper hole (11 ), an anchor point is formed for the cylinder (20) for pushing motion. As a result of the pushing motion of the cylinder (20), the middle articulation component (30), to which it is connected, makes rotating motion around the z-axis. In the vertical foot position, as a result of the angular motion of the middle articulation component (30), the lower foot articulation (40), which also has a connection and/or bond with it in a way that it would have angular motion, moves perpendicular to the ground plane and takes the position given in Figures-2 and 3. The position given in these figures is the position that the construction equipment takes in cases where it has to operate at narrow areas.
When the construction equipment operates in a wide area, it takes the position called as outwardly extending foot, given in Figure-1 and Figure-4. Motion of this position occurs as follows: The cylinder (20) again makes pushing motion as told in the above paragraph. However, the pushing motion is greater this time. With the increase of cylinder (20) pushing distance, the middle articulation component (30) and the lower foot articulation (40) are brought to a linear position and fixed, rotating motion is made around the z-axis with larger angle. However, before the greater pushing motion of the cylinder (20), the mode pin (90) has to be attached to the middle articulation component (30) mode pin hole (33). In this way, the position called outwardly extending foot is obtained.
Chassis (10) upper hole (11 ) and the bore hole (21 ) of the cylinder (20) are made concentric and they are fixed with the fixation pin (91). Middle articulation component (30) pin hole (31 ) is fixed to the chassis lower hole (13) again with the help of a fixation pin (91). The rod hole (22) of the cylinder (20) remaining at the lower part is fixed to the cylinder pin hole (32) with a fixation pin (91). The lower foot (40) 4-bar pin hole (41) and the middle articulation component 4-bar pin hole (34) are fixed to each other via a fixation pin (91). This fixation pin (91), at the same time, passes through the intermediate bearing component 4-bar pin hole (72). One of the holes of the links (50, 60) are connected to their chassis middle holes (12), while their holes found at their other ends are connected to the link pin holes (71 ) with the help of fixation pins (91). The base (80) is placed between the lower foot base pin holes (43) and fixed with the fixation pin (91 ).
There are 2 restraints for the base (80) having degree of freedom on the lower foot articulation (40). One of them determines the place where it has to stay in outwardly extending foot position, while the other one determines the place to stay in vertical foot position. All of the described parts are made during the production operation. They can not be changed by operators. Having the outwardly extending foot and the vertical foot systems in the same machine via this novelty and the transition between these systems are going to be described below. When the stabilizer foot is wanted to be used in outwardly extending foot position, the middle articulation component mode pin hole (33) and the lower foot mode pin hole (42) are brought to concentric position and fixed with the mode pin (90). Pushing motion would be formed as a result of actuation of the cylinder (20) via the hydraulic system. When it is desired to be used in the vertical foot position, the mode pin (90) is removed from the previously told position and fitted by being passed through the intermediate bearing component mode pin hole (73) and the lower foot mode pin hole (42). Cylinder would be actuated via the hydraulic system and then the cylinder would be opened and the feet will be placed on the ground in the same way.
In this novel stabilizer mechanism, mode pin (90) changing system is manual in the vertical foot system. In the future, this can be improved, automatized, and implemented by pressing a button found inside the operator cabin.
