Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
The present embodiment provides a soft crossing insulator changer, as shown in fig. 1-2, comprising two rod-shaped transmission ratchets 1, four transmission rods 2, two ratchet wrenches 3 and two cable fixing buckles 4; the outer surface of each rod-shaped transmission ratchet wheel 1 is respectively meshed with a ratchet wrench 3; the outer surface of each transmission rod 2 is provided with an external thread, two ends of each rod-shaped transmission ratchet wheel 1 are respectively in threaded connection with one transmission rod 2, the external thread directions of the transmission rods 2 connected with the two ends of each rod-shaped transmission ratchet wheel 1 are opposite, and internal threads matched with the external threads of the connected transmission rods 2 are arranged inside the two ends of each rod-shaped transmission ratchet wheel 1; the two rod-shaped transmission ratchet wheels 1 are arranged in parallel, and the two cable fixing buckles 4 are respectively positioned at two sides of the rod-shaped transmission ratchet wheels 1 in the axial direction; the inner side of each cable fixing buckle 4 is of an open structure, and the two ends of the inner side of each cable fixing buckle are fixedly connected with one transmission rod 2 respectively.
The working principle of the soft crossing insulator changer comprises the following steps: when the soft crossing insulator needs to be replaced, the two ratchet wrenches are shaken firstly, so that each rod-shaped transmission ratchet wheel drives the two transmission rods connected with each other to extend outwards, the thread fixing buckles on the two sides are driven to move outwards, and the distance between the two thread fixing buckles is increased. Then the soft crossing insulator is placed in a space between the two thread fixing buckles, the ratchet wrench is reversely shaken, each rod-shaped transmission ratchet wheel drives the two transmission rods connected to contract inwards, the thread fixing buckles on the two sides are driven to move inwards, the distance between the two thread fixing buckles is reduced until the thread fixing buckles on the two sides are clamped to the wire clamps connected to the two sides of the soft crossing insulator, the ratchet wrench is shaken to enable the distance between the thread fixing buckles on the two sides to be slightly shortened, at the moment, the soft crossing insulator changer can replace the soft crossing insulator to connect threads, and the soft crossing insulator is free of stress. And after the original soft crossing insulator is disassembled and a new soft crossing insulator is replaced, the wire clamps on two sides are tightly connected with the soft crossing insulator. And finally, the ratchet wrench is shaken to increase the distance of the cable fixing buckles on the two sides until the soft-span insulator changer can be detached from the soft-span insulator.
Further, in this embodiment, the cable fixing buckle 4 is a cube.
In this example, the total length of the soft cross insulator changer is 960mm in terms of shrinkage and 1360mm in terms of total extension. The size can basically meet the operation requirements of various replacing soft cross insulators.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
