Description

A large span cross-arm fixture assembly

technical field

The utility model relates to the technical field of power tools, in particular to a large-gear cross-arm fixture assembly.

Background technique

At present, due to the needs of modern economic development and the requirements for the safety distance of crossing objects, the design of transmission line towers is getting higher and higher, the diameter of wires is getting larger and larger, and the stress of wires is also increasing. When conducting wire operations, it is necessary to use Use the cross-arm jig to lift the wire, but the following defects exist when using the traditional cross-arm jig for lifting operations: 1. Because the ordinary cross-arm angle material cannot bear the stress when the wire is lifted, it is easy to bend the angle bar when using the ordinary cross-arm jig. 2. The existing thread-lifting screw method cannot meet the operation requirements of large-gear towers, and it is easy to cause damage to tools and equipment due to uneven force or insufficient force on the screw during the operation process. An electric shock accident occurred.

Contents of the invention

The purpose of this utility model is to provide a cross-arm fixture assembly that is convenient and flexible in operation, high in safety factor, and suitable for large-gear operations in order to solve the above-mentioned problems in the existing cross-arm clamps in construction operations.

The specific scheme of the utility model is: a large-gear cross-arm fixture assembly, which has a cross-arm auxiliary device, and a card seat is provided at each end of the cross-arm auxiliary device, and a threaded through hole is provided in the middle of the card seat. There is a casing above each card seat, the inner wall of the casing is threaded, and an operating handle is provided on the outside of each casing, and a tightening screw rod is installed through each card seat and the corresponding casing successively. , the lower end of the tightening screw rod is hinged with an insulating pull plate, and the lower end of the insulating pull plate is hinged with a wire hook through a connector; a safety bolt is respectively arranged on the outside of the tightening screw rod at both ends of the cross-arm auxiliary tool .

In the utility model, two sets of cross-arm fixing devices are provided in the middle of the cross-arm auxiliary device. The cross-arm fixing devices include long bolts and hooks. Strip holes are opened on the hooks, and the long bolts pass through The strip hole is threadedly connected with the cross-arm auxiliary device.

The operating handle described in the utility model is a ratchet wrench matched with the casing outer wall.

In the utility model, a gasket is also provided between the card seat and the corresponding sleeve.

When the utility model is working, the cross-arm fixing device can be fixed on the pole tower, and then the decks on both sides can be moved left and right to adjust to a suitable position, and then the two tightening wire rods can be adjusted by turning the operating handles on both sides of the cross-arm auxiliary device. , so that the wire hook at the front end of the insulation pull plate can be hooked to the wire for corresponding operations; the utility model has the advantages of simple structure, convenient operation, higher operation safety factor, and can adapt to the working environment with large gear distances at the same time, and has good practical application value .
