Description

Technical Field

[0001] This utility model relates to the field of power operation and maintenance technology, and in particular to a power operation and maintenance protection device with safety protection function. Background Technology

[0002] In a power system, power plants convert natural primary energy into electrical energy and transmit it to distant power users. To reduce energy loss and voltage drop on transmission lines, the voltage needs to be increased. To meet the safety needs of power users, the voltage needs to be decreased and distributed to each user. This requires substations that can increase and decrease voltage and distribute electrical energy. To ensure the safety of power transmission, transmission lines need to be inspected. When inspecting transmission lines, workers usually use maintenance platforms to ascend to a high position to inspect the lines. To ensure the personal safety of workers, protective plates are usually installed on the maintenance platforms to prevent workers from falling, thus achieving a safety protection effect.

[0003] Chinese Patent CN219371864U discloses a power maintenance protection device with safety protection functions. A protective plate is fixedly connected to the top surface of the maintenance platform. A winding assembly for winding up wires is provided on the surface of the protective plate, and a locking assembly for limiting the winding assembly is also provided on the surface of the protective plate. The winding assembly has limit holes. However, the aforementioned patent has certain drawbacks. It lacks the ability to assist in unloading and loading the wire coils as described in the claims. Manual loading would increase the workload of personnel and reduce the functionality of the equipment. Therefore, we propose a power maintenance protection device with safety protection functions to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a power operation and maintenance protection device with safety protection function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A power operation and maintenance protection device with safety protection function includes a protection device body. The protection device body has a steering assembly inside. The steering assembly includes a first motor. The output end of the first motor is connected to a steering rod. The top end of the steering assembly is connected to a displacement assembly. The inner side wall of the displacement assembly is inlaid with two bearing seats. The inner rings of the two bearing seats are connected to a lead screw. The outer surface of the lead screw is threaded with a mounting seat. The rear end of the lead screw is connected to a second motor. One side of the displacement assembly is connected to a lifting assembly. The output end of the lifting assembly is connected to a winding wheel. The output end of the winding wheel is wound with a wire rope. The bottom end of the wire rope is connected to a hook.

[0007] In a further embodiment, a switch door is hinged to the left side of the protective device body via a pin, and a limit component is installed on one side of the switch door.

[0008] In a further embodiment, a placement seat is installed on the front of the protective device body, a screw is provided in front of the placement seat, a limit plate is connected to the front end of the screw, and the screw is adapted to the placement seat.

[0009] In a further embodiment, the inner wall of the protective device body is connected to two positioning cylinders, and the inner wall of each positioning cylinder is slidably connected to the outer surface of the steering rod.

[0010] In a further embodiment, a reinforcing block is connected to the outer surface of the first motor, and the bottom surface of the reinforcing block is connected to the inner bottom wall of the protective device body.

[0011] In a further embodiment, the outer surface of the mounting base is slidably connected to the inner wall of the displacement assembly, and the outer surface of the second motor is connected to one side of the displacement assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses the rotation of the first motor to enable the steering rod to finely adjust the wire coil left and right, improving the functionality of the equipment. In conjunction with the rotation of the second motor, the lead screw rotates within the inner ring of the bearing housing. Furthermore, the threaded connection between the lead screw and the mounting base, and the sliding connection between the mounting base and the displacement assembly, allows the wire coil to move back and forth, facilitating its hoisting. Simultaneously, the rotation of the lifting assembly enables the winding wheel to wind the wire rope and the hook to lift the wire coil, reducing the workload for personnel and the intensity of installation.

The outer surface of the mounting base 303 is slidably connected to the inner wall of the displacement component 3. The outer surface of the second motor 304 is connected to one side of the displacement component 3. This can improve the smooth movement of the mounting base 303 and prevent it from swinging.

[0025] The working principle of this utility model is as follows:

[0026] First, install it at the designated location and hang the hook 403 inside the wire reel. Then, start the lifting assembly 4 to make the winding wheel 401 wind up the wire rope 402, and the wire reel will follow the lifting. Then, the rotation of the second motor 304 will cause the lead screw 302 to drive the mounting base 303 and the wire reel to move. If necessary, start the first motor 201 to make the steering rod 202 adjust left and right slightly. At the same time, the wire reel will rise to the level of the placement base 5. Then, insert the wire reel into the outside of the placement base 5 and use the screw 6 and the limiting plate 7 to limit it. The above is the complete usage process of this utility model.
