[0001] The invention relates to the technical field of hanging bracket equipment for anti-falling lines, in particular to a hanging bracket for setting up an anti-falling line for a transmission line tower climbing device by an unmanned aerial vehicle. Background Art

[0002] During regular maintenance of the transmission line tower, workers are required to climb the tower to perform high-altitude work, and the workers need to wear corresponding anti-fall equipment before climbing the tower. At present, most workers need to climb to a high place to fix the fixed end of the anti-fall equipment on the transmission line tower when they are working. This not only wastes a lot of physical strength of the workers, but also greatly reduces the workload of the workers. In addition, it is very easy to fall during the climbing process, which greatly reduces the personal safety of the workers. For this reason, a bracket for a drone to set up a transmission line tower anti-fall line is proposed. Summary of the invention

[0003] The purpose of the present invention is to provide a bracket for a drone to set up a transmission line tower climbing anti-fall line, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a rack for setting up a transmission line tower climbing anti-fall line for a drone, comprising a main frame mechanism, the main frame mechanism comprising a drone body, the drone body being fixedly connected to an electric push rod, a support frame being arranged at the bottom of the drone body, a disassembly assembly being arranged at the top inside the support frame, a clamping assembly being arranged at the bottom inside the support frame, an anti-slip assembly being arranged inside the clamping assembly, the clamping assembly comprising two support rods, the number of the two support rods being two, the two support rods being symmetrically arranged with the support frame as the center, the tops inside the two support rods being connected to the left side of the support frame through a pin shaft The two sides of the support frame are rotatably connected, and the sides where the two support rods are close to each other are both provided with external teeth. Rack two are provided on the left and right sides of the bottom of the support frame. The sides where the two racks are far away from each other are meshed and connected with the sides where the two support rods are close to each other. The bottoms of the two support rods are fixedly connected with fixing clamps. When the moving block moves upward, it will drive the rack two to move together. When the rack two moves upward, it will drive the two support rods to approach each other. At the same time, the two fixing clamps will also approach each other and clamp the angle iron to prevent the staff from climbing high to hang the bracket.

[0005] Furthermore, the corresponding sides of the two fixing clamps are both opened, and limiting plates are provided on the tops of the two fixing clamps. The sides of the two limiting plates that are away from each other are fixedly connected to the side corresponding to the second support rod. The two limiting plates are arranged in a vertical array, and limiting grooves are provided inside the two limiting plates. When the rack two moves upward, it will drive the two support rods two to approach each other, and at the same time, the two fixing clamps will also approach each other through the support rod two.

[0006] Furthermore, the anti-slip assembly includes a rotating shaft, the front and back sides of the rotating shaft are fixedly connected to the front and back sides of the bottom inside the support frame, a gear is fixedly connected to the outer surface of the rotating shaft, a rack three is arranged on the right side of the rotating shaft, and the left side of the rack three is meshed with the outer surface of the gear, and when the support rods two approach each other, they will also drive the limit plates to approach each other, and at the same time, when the moving block is driven to move upward, it will drive the rack three to move upward, and when the rack three moves, it will drive the gear to rotate, and because the rotating shaft is fixedly connected to the support frame, the rotating shaft provides a certain support for the gear through the support frame, and when the gear rotates, it will drive the rack four to move downward.

[0007] A rack four is provided on the left side of the rotating shaft, and the right side of the rack four is meshed with the outer surface of the gear. The front and back sides of the rack four are fixedly connected with sliders.

The bottom of the rack four is fixedly connected with a limit rod, and the outer surface of the limit rod contacts the inside of the limit groove. Then, the slider will move along with the movement of the rack four and slide on the front and back sides of the support frame. At the same time, the slider also provides certain support for the movement trajectory of the rack four. When the rack four moves, it will drive the limit rod to move downward. When the limit rod moves, it will be inserted into the two limit grooves and limit the limit plate, which also limits the fixing fixture to prevent the equipment from falling off.

The outer surfaces of the two support plates are fixedly connected to the left and right sides of the inside of the support frame. When the moving block moves, the spring will be squeezed, and the spring will shrink due to the limiting effect of the support plate so that the moving block can continue to push.

[0010] Furthermore, the left and right sides of the bottom of the support frame are rotatably connected with support rods 1 through pin shafts, and the sides of the two support rods 1 that are close to each other are provided with external teeth, and the sides of the two racks 1 that are away from each other are meshed with the sides of the support rods 1 that are close to each other. The tops of the two support rods 1 are fixedly connected with clamping rings, and when the moving block moves, it will drive the racks 1 to move downward together. Since the corresponding side of the bottom of the support rod 1 is meshed with the side of the rack 1 that is away from each other, when the rack 1 moves downward, it will drive the two support rods 1 to approach each other, and at the same time, the two clamping rings will also approach each other through the movement of the support rod 1 and clamp the electric push rod, and at the same time, the drone body is fixedly installed. The simple and convenient installation method greatly saves the operating time of the staff.

[0011] Furthermore, a telescopic rod is in contact with the inside of the support frame, the top of the telescopic rod is fixedly connected to the bottom output end of the electric push rod, the back of the support frame is fixedly connected to a hanging bracket, and a safety rope is provided at the bottom of the hanging bracket.
