Description:
The method of installation of steel power line poles.

The subject of the invention is the method of installation of steel poles of power lines, which shortens the time of their installation and reduces the costs of installation. The positioning of the pole itself, which is a time-consuming operation, can be carried out without the use of a crane, which significantly reduces the cost of erecting the poles. -/-

Reinforced concrete lighting pole reinforced with longitudinal and circular steel rods, with central two-diameter hole technologically converging upwards is known from patent description PL197355, consisting of upper pole with cross-section in the shape of a circle or polygon with a thickening at the bottom ended with a plane below which a central truncated cone or a correct truncated pyramid is made, converging to the bottom, with an apex angle of 0° ~ 0 56°, and at its smaller diameter a steel flat bar with a central hole perpendicular to the axis is concreted and from the lower, foundation part made with a central two-diameter hole converging to the top, ending from the top with a central hole converging downwards in the shape of a central truncated cone or a correct truncated pyramid with an apex angle corresponding to the apex angle of the cone in the lower part of the pole, and at its smaller diameter, in the central hole in the steel flat bar concreted perpendicular to the axis with a central hole, a nut is fixed axially with a vertical hole cooperating with a screw penetrating the flat bars from the top. -/-

In turn, a· prefabricated reinforced concrete pole, which contains a ground part and a foot for positioning and fixing on the ground is known from the patent description PL21 1814, with an intermediate part between the ground part of the pole and the foot, whose lower end is fixed to the foot fixed to the ground, and the other end is fixed in the ground part of the pole. The ground part of the pole has at least one groove, situated in one of its walls, intended for the attachment of wall panels or other flat elements. -/-

Patent application P.377800 indicates the assembly method as an articulated connection between the lower part of the steel element and the foundation element, where the connection is made in the horizontal position of the steel element and then lifted by means of a rigid rod connected to the jib by means of a traction device. The kit for vertical setting of steelwork elements such as the pole and the chimney consists of a spatial jib, mounted on a steel element, a rigid rod connected to the corner of the jib and the tractor as a traction device. -/-

The purpose of the invention is to provide a solution concerning the method of assembly of the steel power line poles, which will provide the shortening of the time of assembly of power line poles, eliminate heavy assembly cranes, and thus enable the reduction of the cost of assembly of the power line poles. -/-

The method of assembling the pole according to the invention consists in joining the steel power pole at the level of 0.00 on the assembly supports in the horizontal position, then assembling the multifunctional auxiliary structure on the pole foundations, assembling the rotary frame, reinforcing the pole with the auxiliary structures and assembling the actuators with the rigging system and then raising the pole in six phases using the hydraulic actuators to the target position. Once the components of the steel power pole have been delivered to the erection site, the ancillary structures for the erection of the pole have been delivered to the erection site, the assembly supports have been positioned and the complete pole has been joined horizontally, using a forklift truck and scaffolding or assembly lifts, in several phases using hydraulic actuators, the integrated pole is lifted. -/-

The advantage of the invention is the elimination of the heavy equipment used so far, as well as the construction of special access roads, even if it is not possible to get to the site with the deliveries of pole elements, it is possible to reload the supplies and transport them with a tractor and trailer to the place of assembly. -/- The object of the invention is shown in the examples of the execution in the drawing in which fig. 1 shows the first phase of the assembly of the steel pole, fig. 2 shows the second phase of the pole assembly from the level 0.00 to 30° , fig. 3 shows the third phase of the pole assembly from an angle of 30° to 45°, fig. 4 shows the fourth phase of the assembly from an angle of 45° to 60°, fig. 5 shows the fifth phase of the assembly from an angle of 60° to 85° and fig. 6 shows the sixth phase of the assembly from an angle of 85° to 90° using a set of bolted fixing and stabilizing structures with the pole foundation. -/- In the example design, the E33P straight-line pole model was used for assembly, which is marked with the number 9 in the figure. -/-

Fig. 1 shows a method which consists in horizontal integration of a complete steel pole 9 on three assembly supports 4. -/-

Fig. 2 shows the raising of the pole from the level of 0.00†o the angle of 30° using hydraulic actuators 7 and multifunctional auxiliary structures 2 two sets, fixed to the foundation feet 1 , and the rotating frame 3 fixed in the lower part to the auxiliary structure 2, while to the upper part of fhe rotating frame 3 the rigging system 8 is fixed, used to raise the pole 9 using the rope fixing elements on the upper level of the pole 5, and rope fixing elements on the lower level of fhe pole 6. -/-

The process of lifting the steel pole 9 is shown in fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6, showing the subsequent phases of lifting Phase 2, Phase 3, Phase 4, Phase 5 and Phase 6. -/-

The rotary frame 3 is fixed in the lower part to the auxiliary structure 2, the auxiliary structures 2 are fixed to the foundation feet 1 of pole 9 which are fixed in fhe aboveground par† of the pole, and to the upper part of fhe rotary frame 3 fhe rigging system 8 is fixed, used for raising the pole 9. -/-

The elements of fhe assembly support 2 are screw systems for lowering the pole in the last phase of vertical alignment - transition from phase 5†o phase 6. -/- To the second set of auxiliary structure 2 hydraulic actuators 7 used for lifting pole 9 are attached. Another assembly variant assumes the use of a frame built in fhe form of a ladder made of metal profiles with a square cross-section, which is equipped with two vertical rotating elements mounted on supports resting on reinforced elements of fhe frame. To fhe lower par† of fhe frame and upper rotating elements a load-bearing rope is fixed, connecting the frame with the mounted pole. The frame has a number of mounting holes for assembly of rotating elements, adjusting the lifting height. The load-bearing frame and vertical rotating elements are additionally connected with elements in the upper part of the frame, which at fhe same time serve as an additional bracket for the mounted pole. -/-
