Portable double-disk circulation wire tightening device and adopted wire tightening method

Abstract

The invention discloses a portable double-disk circulation wire tightening device and an adopted wire tightening method. The portable double-disk circulation wire tightening device comprises a ratchet wire tightening mechanism, and a movable wire pulling mechanism and a fixed wire pulling end which are arranged at both ends of the ratchet wire tightening mechanism, wherein the ratchet wire tightening mechanism comprises two wire stranding boxes installed on a bearing frame side by side; each wire stranding box is coaxially and fixedly connected with one of two groups of ratchets, and the wire stranding box and the group of ratchets are installed on a wire box rotating shaft on the bearing shaft in a rotated manner; each group of the ratchets is provided with a lock-up pawl and a transmission pawl, the lock-up pawls are installed on the bearing frame, and the transmission pawls are installed on a turning handle connected with the wire box rotating shaft; the two groups of transmission pawls are connected with a pawl clutch adjuster; and the movable wire pulling mechanism is divided into two groups which are connected with the two wire stranding boxes through traction wires, and the fixed wire pulling end is connected with the bearing frame. The portable double-disk circulation wire tightening device is simple in structure, is convenient and effortless in operation, is very convenient to carry, can effectively reduce manpower and labor intensity, and avoids the wire clamping problem of the traction wires.

Description

technical field [0001] The invention relates to the field of electric power distribution line construction, in particular to a portable double-disk circulation wire tightener and a wire tightening method applied thereto. Background technique [0002] In the construction work of power distribution, pulling and connecting wires is one of the main tasks. Power distribution wires generally have a long length and a large weight. It takes a very large pulling force to connect the wires between the two poles. Pulling the wires by manpower not only requires more people, but also takes time and effort. It is difficult to meet the construction requirements; therefore, in order to reduce the workload, it is usually necessary to use a tensioner to tighten the wires to be connected when the wires are connected. [0003] Most of the existing tensioners for pulling and connecting wires are one-way tensioners. The main structure includes a fixed wire end, a movable wire end and a ratchet w...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in view of the existing wire tensioner in the construction process of pulling and connecting wires, there are many manpower requirements, high labor intensity, easy occurrence of wire jamming, and the labor and power consumption of the existing wire tensioner. When it is necessary to carry multiple wire tensioners, a new type of portable double-disc loop wire tensioner and its applied wire tightening method are provided.
