[0013] Beneficial Effects

[0014] Compared with the prior art, the present invention provides an anti-falling device for the horizontal guide rail of a high-voltage transmission tower, which has the following beneficial effects:

[0015] 1. The anti-fall device of the horizontal guide rail of the high-voltage transmission tower is configured such that when the horizontal guide rail and the limit block enter the fixed frame through the placement cavity, the first pulling handle is pressed toward the fixed frame. The first pulling handle drives the limit tooth plate and the first driving gear to separate from each other through the connecting extrusion plate, and the connecting extrusion plate drives the first extrusion spring to extend when it moves, thereby facilitating the restriction of the placement cavity.

[0016] 2. The anti-fall device of the horizontal guide rail of the high-voltage transmission tower is configured by rotating the first rotating column, which will drive the first driving gear to rotate when the first rotating column rotates. When the first driving gear rotates, it will drive the first threaded column to rotate through the first driven gear. When the first threaded column rotates, it will drive the first limiting plate to move in the placement cavity through the moving block and contact the horizontal guide rail, release the first pulling handle, and under the action of the first extrusion spring, the limiting tooth plate and the first driving gear are connected to each other, so that the first rotating column cannot rotate, and the first threaded column will also be unable to rotate, and the first limiting plate cannot move, thereby limiting the movement of the horizontal guide rail.

[0017] 3. The anti-falling device of the horizontal guide rail of the high-voltage transmission tower drives the second threaded column to rotate through the motor through the second driving gear and the second driven gear. When the second threaded column rotates, it moves toward one side of the horizontal guide rail through the L-shaped block, and the plug-in column on one side of the L-shaped block is connected to the plug-in groove in the limit block, so that the horizontal guide rail is restricted from moving, thereby preventing the horizontal guide rail from falling.

[0018] 4. The anti-fall device of the horizontal guide rail of the high-voltage transmission tower has two ends of the horizontal guide rail restricted and fixed by a fixing frame, and is provided with a plug-in column and a plug-in groove to prevent the movement of the horizontal guide rail, further increasing the anti-falling property of the horizontal guide rail.
