Ratchet type double locking structure for assisting steel wire rope in pulling aerial cable

Abstract

The invention provides a ratchet type double locking structure for assisting a steel wire rope in pulling an aerial cable and relates to the technical field of power transmission and distribution. According to the ratchet type double locking structure, the phenomena that double locking of a winding structure cannot be realized, and the locking structure is easily damaged under the action of own tension of the steel wire rope are avoided; and the problems that the clamping of the steel wire rope cannot be realized, and the clamping of the steel wire rope and the adjustment of a winding drum cannot be mutually linked and matched are solved. The ratchet type double locking structure for assisting the steel wire rope in pulling the aerial cable comprises a mounting bracket and an unlocking rod, wherein a winding structure is arranged on the mounting bracket; in addition, the steel wire rope winds the winding structure; and an adjusting structure is arranged on the mounting bracket. An adjusting handle is in threaded connection with an adjusting rod; when the rear end face of the adjusting handle makes contact with the front end face of a baffle ring, a prismatic bar is in an ejection state at the same time; besides, a sliding seat is in a rearward movement state and a locking structure is in an unlocking state at the moment, and further rotary winding of the winding drum can be realized by continuously rotating the adjusting handle.

Description

technical field [0001] The invention belongs to the technical field of power transmission and distribution, and more specifically relates to a ratchet type double locking structure for auxiliary wire rope traction of high-altitude cables. Background technique [0002] The steel wire rope is a spiral steel wire bundle that twists the steel wires that meet the requirements of mechanical properties and geometric dimensions according to certain rules. Hanging, and after a period of use, the steel wire rope is easy to loosen and sag due to the influence of the gravity of the steel wire rope itself and the gravity of the cable. [0003] For example, the application number: CN201911174697.3, the present invention relates to the technical field of steel wire rope, especially the wire rope locking and fixing mechanism, including an L-shaped cover plate and a U-shaped groove, the L-shaped cover plate is installed on one side of the U-shaped groove, and the U-shaped groove Chemical bo...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a ratchet-type double locking structure for auxiliary wire rope traction of high-altitude cables to solve the existing problem that the existing device has a single locking structure when adjusting the wire rope for winding and tensioning, and cannot Realizing the double locking of the rewinding structure will easily lead to damage to the locking structure under the tension of the steel wire rope itself. Moreover, although the existing device can realize the locking and locking of the reel, it cannot realize the clamping of the steel wire rope. The problem that the clamping of the wire rope and the adjustment of the winding drum cannot be coordinated with each other
