Description

Technical Field

[0001] The utility model belongs to the technical field of electric power towers, and in particular relates to an electric power tower with adjustable cable clamping. Background Art

[0002] Power towers are tower-shaped structures used for power transmission. Their structural characteristics are that all tower types are spatial trusses, with members primarily composed of single equilateral angle steel or composite angle steel, typically made of Q235 (A3F) and Q345 (16Mn). Members are connected by bolts, which are used to withstand shear forces. The entire tower is composed of angle steel, connecting steel plates, and bolts.

[0003] Chinese patent CN211851154U discloses an electric tower with adjustable height and angle, which relates to the technical field of electric towers. The electric tower includes a base, the upper end of which is fixedly connected to a tower body, wire hanging frames on both sides of the upper end of the tower body, wire hanging pieces installed at the front ends of the wire hanging frames, and an adjustment mounting piece provided between the wire hanging pieces and the wire hanging frames.

[0004] At present, the height and angle of the hanging parts on some power towers are fixed and cannot be freely adjusted, which makes it inconvenient to connect the hanging wires. In the above-mentioned documents, the hanging parts can be rotated by the rotating shaft to adjust the hanging angle, but the cable needs to pass through the hanging tube. The sealing rubber ring in the hanging tube and the cable are in interference fit, which is not convenient for the cable to be passed through.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0030] See also Figures 1-6 As shown, the utility model is an electric power tower with adjustable cable clamping, comprising a tower 1, an outer surface of the tower 1 is provided with a lifting assembly 2, the bottom of the lifting assembly 2 is fixedly connected to a first rotating assembly 3, the bottom of the first rotating assembly 3 is fixedly connected to a second rotating assembly 4, the bottom of the second rotating assembly 4 is fixedly connected to a mounting assembly 5, the rotation axes of the first rotating assembly 3 and the second rotating assembly 4 are perpendicular to each other, the lifting assembly 2 is used to adjust the height of the mounting assembly 5, the first rotating assembly 3 and the second rotating assembly 4 are used to adjust the angle of the mounting assembly 5, and the mounting assembly 5 is used to fix the cable.

[0031] After the staff climbs up the tower 1, they drive the lifting assembly 2, which drives the first rotating assembly 3, the second rotating assembly 4 and the installation assembly 5 to move up and down, adjusts the height of the installation assembly 5, and pushes the first rotating assembly 3 and the second rotating assembly 4 to rotate, so that the installation assembly 5 can adjust the angle along with the second rotating assembly 4. After the adjustment is completed, the installation assembly 5 is separated. At this time, the cable can be passed through the installation assembly 5. After the cable is passed, the installation assembly 5 can be reset.

[0032] The utility model connects the second rotating component 4 and the mounting component 5, and the mounting component 5 is fixed at the bottom of the second rotating component 4, so that the mounting component 5 can be adjusted to various angles and heights along with the second rotating component 4. After the position of the mounting component 5 is adjusted, the mounting component 5 is separated. At this time, the distance between the upper and lower parts of the mounting component 5 is increased, and the space for the staff to thread the cables is increased accordingly, which makes it easier for the staff to pass the cables through the mounting component 5.

[0033] In one embodiment, for the above-mentioned lifting assembly 2, the lifting assembly 2 includes a screw barrel 201, the internal thread of the screw barrel 201 is connected to a first screw rod 202, the screw barrel 201 is rotatably connected to the outer surface of the tower 1, the end of the first screw rod 202 is fixedly connected to a lifting plate 203, the outer surface of the lifting plate 203 is slidably connected to a round rod 204, the upper end of the round rod 204 is fixedly connected to the tower 1, and the lower end of the round rod 204 is fixedly connected to a first limit plate 205.

[0034] The screw barrel 201 is rotated, and the rotation tendency of the first screw 202 on the screw barrel 201 is blocked by the lifting plate 203 and the round rod 204. When the first screw 202 cannot rotate with the screw barrel 201, the screw barrel 201 can drive the first screw 202 and the lifting plate 203 to move up and down. The first limit plate 205 on the round rod 204 limits the movement distance of the lifting plate 203 and the first screw 202 to prevent the first screw 202 from falling out of the screw barrel 201.

[0035] In one embodiment, for the above-mentioned first rotating component 3, the first rotating component 3 includes a rotating seat 301, the rotating seat 301 is rotatably connected to the lifting plate 203, and the outer surface of the rotating seat 301 is provided with a first limiting hole 302, and the internal thread of the first limiting hole 302 is connected with a first bolt 303, and the first bolt 303 is threadedly connected to the lifting plate 203.

[0036] The lifting plate 203 drives the rotating base 301 to adjust the height. The first bolt 303 on the rotating base 301 is rotated so that the first bolt 303 is separated from the first limiting hole 302 on the rotating base 301. At this time, the limiting fixation between the rotating base 301 and the lifting plate 203 can be released, and the rotating base 301 can be pushed to rotate to adjust its angle. After the adjustment is completed, the bolt 303 is screwed back so that the bolt 303 enters the appropriate first limiting hole 302 on the rotating base 301, and the rotating base 301 can be limited and fixed again.

[0037] In one embodiment, for the above-mentioned second rotating component 4, the second rotating component 4 includes a connecting seat 401, the outer surface of the connecting seat 401 is rotatably connected to a pin shaft 402, the outer surface of the pin shaft 402 is fixedly connected to a rotating plate 403, the outer surface of the connecting seat 401 is provided with a second limiting hole 404, the interior of the second limiting hole 404 is penetrated by a second bolt 405, the outer surface of the second bolt 405 is threadedly connected to a first nut 406, and the connecting seat 401 is fixedly connected to the bottom of the rotating seat 301.

[0038] The rotating seat 301 can drive the connecting seat 401 to rotate. The first nut 406 on one side of the connecting seat 401 is removed to separate it from the second bolt 405, and then the second bolt 405 is pulled out from the second limiting hole 404. At this time, the second bolt 405 is separated from the rotating plate 403, releasing the limiting fixation of the rotating plate 403, and pushing the rotating plate 403 to rotate around the pin shaft 402 can adjust its pitch angle. After the adjustment is completed, the second bolt 405 is inserted into the second limiting hole 404, and the second bolt 405 is passed through the connecting plate 403.

[0040] Rotate the second nut 506 to make it move upward along the second screw rod 502. At this time, the second nut 506 no longer fixes the lower plate 504 to the bottom of the upper plate 501. The lower plate 504 moves downward under the action of gravity, and the distance between the lower plate 504 and the upper plate 501 increases. The staff can insert the cable into the threading holes 505 on the surface of the upper plate 501 and the lower plate 504, push the lower plate 504 to move upward, rotate the second nut 506 to make it return to the top of the upper plate 501, and fix the lower plate 504 and the upper plate 501 together.

[0041] In one embodiment, for the upper plate 501 , a circular hole 6 is formed on the outer surface of the upper plate 501 , and the diameter of the circular hole 6 is slightly larger than the diameter of the second screw 502 .

[0042] In one embodiment, for the above-mentioned screw barrel 201 , a handwheel 7 is fixedly connected to the outer surface of the screw barrel 201 .

[0043] The circular hole 6 is provided to facilitate the lower plate 504 to drive the second screw 502 to slide, thereby preventing the second screw 502 from getting stuck. The hand wheel 7 facilitates the staff to push the screw barrel 201 to rotate.

[0044] When the second screw 502 is moved upward, the lower plate 504 and the upper plate 501 are no longer fixed by the second nut 506, and the lower plate 504 can move downward under the action of gravity, thereby increasing the distance between the lower plate 504 and the upper plate 501, making it convenient for the staff to pass the cable through the lower plate 504 and the upper plate 501.
