LOADED OR UNLOADED

Technical Field The invention is about a lifting system with locking piston and magnetic check valve designed to lift any type of loads, construction equipment, concrete blocks, debris blocks, health and hospital equipment, elevator mechanisms and especially road vehicles (with or without tires), aircrafts and marine vehicles for the purposes of deployment, maintenance, repair, relocation as well as to hold this as loaded in a secure way, as an innovation introduced to gas, pneumatic, hydraulic piston systems that can be mounted on vehicles or any lifting system installed individually.

Background Art

Currently there are techniques available using mechanical, hydraulic, pneumatic pistons for processes of lifting, repair, and maintenance of loads, especially vehicles, at short heights. Such techniques are based on the principle of performing the uplifting by establishing a connection between the load and ground through pistons where pressurized fluids, air, gas or plasmas are pumped into. Besides these techniques and tools used, extra procedures and apparatus are required in order to maintain the stability of the load. For example, mechanical jacks are placed at hard- to-reach points of the vehicles in order the perform repair work of a road vehicle with a flat tyre, the lifting is handled by arm and supports are placed at different points in order ensure safety. The use of jacks is applicable to uplifting of miscellaneous loads besides vehicles, however requires extra tools, equipment and man power for heavy tonnage loads. The known disadvantage of this technique is that it requires a smooth surface; high number of tools and equipment used which take up too much space; and most importantly, that it presents work insecurity. Mechanical or hydraulic jacks used in uplifting may be disengaged suddenly when loaded due to a system failure resulting in falling of loads, material damage, job accidents, injuries and even death. When working under lifted loads or replacing a tire, it is common that people are injured by being trapped under the load due to load discharge. The said invention can be used integrated with existing hydraulic, pneumatic and electromechanical systems of vehicles, performing the lifting job without requiring man power and introducing an innovation by preventing sudden discharge of pressure lifting the load thanks to built-in magnetic check valves and reverse-operating pistons with lock mechanism. The magnetic check valve, another safety item of the system, has been updated compared to conventional check valves with the capability of operating with an electromagnet to cut off the fluid, oil, air, gas or steam flowing from the opposite direction and to keep these in the system. This allows pistons to do their jobs which is securing the load position and fulfilling safety functions. The invention provides the opportunity for assembly in various ways that the own parts can create different schemes depending on the positioning preferences and therefore provides ease of application especially on vehicles. The said invention, by being placed in the spaces of vehicle handles the performance of uplifting the vehicle without requiring any external intervention of man power. Moreover, thanks to the connection points like the air chuck on the system, tools such as pressurized air hex wrenches can be attached to and used with the system. The said invented system, performing load uplifting and upholding while at the same time introducing an innovation in ensuring safety by preventing sudden discharges thanks to the system parts of locking pistons and magnetic check valve, either can be used on vehicles equipped with hydraulic, pneumatic, and electromechanical systems and any other type of load lifting equipment with piston or individually by being installed externally in case of the absence of the foregoing.

In accordance with the present invention there is provided a lifting and witholding piston system with safety lock when loaded or unloaded equipped with; two or more pistons(1 ); magnetic check valve block(4); hydraulic tank(5); air tank (9); air chuck(8); control panel (6); and inverter (7). The specification of the system invented is that it is equipped with lock mechanism pistons(1 ), converting the energy from the hydraulic fluids, pressure air, gas or plasmas into pushing movement, allowing integration with existing hydraulic fluid systems (1 1 ), pressure air (pneumatic) systems (10) and electrical engine systems depending on the preference. In case where the said invention to be operated with hydraulic system(1 1 ) power, for example on a vehicle, the locking pistons(1 ,2,3) are extended by the fluid supplied from the vehicle's integrated hydraulic system (1 1 ) and pumped into the locking pistons (1 , 2, 3) to perform, the lifting job. The locking pistons(1 ,2,3) ,as complementary parts of the system, can be integrated in to the existing pressure air system (10) by making necessary connections to perform the same when being operated with air or gas. When the locking pistons(1 ,2,3) extended sufficiently, the lower lock mechanism and top lock mechanism inside the locking pistons(1 ,2,3), locks system and prevent sudden discharge by blocking piston movement as long as no fluid, air or gas is pumped into the piston. The system is engaged with the command given at the control panel (6) as locking pistons(1 ,2,3) are extended by pumping fluid gas or air. The locking pistons (1 , 2, 3) mounted at the center of gravity of the load or vehicle contact with the ground and lift the load as they are extended towards the opposite direction. The locking piston (1 ,2,3), which is the safety and lifting component of the said invention, is equipped with an upper lock mechanism; piston pin (18); lower stand lock mechanism; and stand (23). The piston stand (23) ensuring contact between the pistons and ground can rotate gradually ensuring grip to uneven or inclined surfaces. The locking pistons(1 ,2,3) with double locking mechanism, as part of the system invented, has two lock mechanisms located at the top and lower stand of the piston. The lock mechanism at the lower stand is composed of final roof (20); two safety spring with steel lugs (2); stand interconnection rod (22); and stand (23). The safety spring lugs (21 ) used hereclings to the piston stand (23) to prevent movement of piston (as long as no fluid, air or gas is pumped into the cylinder forming the piston rod). The built-in top lock mechanism located on the top of the piston includes top plug (12); lock flange (16); tightening screw (13); return spring (14); screw pin (15); seal set (17); and piston pin (18). The tightening screw (13) prevents the piston movement as long as no fluid or gas is present in the cylinder. The said upper and lower lock mechanisms of the piston operate together to prevent piston movement in order to fulfill the safety function by eliminating sudden, uncontrolled discharges. Another safety component to ensure safe locking of the lifting and gripping piston when loaded and loaded is the magnetic check valve. It is composed of a magnetic check valve; bronze body (25) to ensure operation under heavy pressure; aluminum slide (35); steel ball (36); steel magnetic end (33); coil body (30); magnetic coil (31 ); return spring (28); hydraulic seal (27); copper gasket (29); O ring (34); and check nut (32) which can be integrated to the existing pneumatic, hydraulic, etc. lifting system at connection ends. The magnetic check valve operates integrated with the locking pistons (1 ,2,3) and the magnetic- controlled steel ball (36) will not move and the fluid, gas and air will remain within the system unless a command is given to the check valve (Figure 5) by feeding air, gas, fluid or plasma to the pistons. This will fix the position of pistons (Figure 2) by locking the system movement. Uncontrolled movement of load from its current location will be prevented by ensuring that the piston is not affected by incidents like leakage, blast or pressure loss that may occur before the pistons in the system.
