Line tightening device for erection of communication line

Abstract

The invention relates to a line tightening device for erection of a communication line. The line tightening device is characterized by being provided with a rotating shaft bracket (1), a rotating shaft (2) is arranged in the rotating shaft bracket (1) and is inserted into the rotating shaft bracket (1) in a penetrating mode, a line hanging column (3) is arranged on the rotating shaft (2) and used for hooking and hanging the communication line, a rotating wheel (4) is fixed to one end of the rotating shaft (2), an insertion hole (5) is formed in the rotating wheel (4), a rotating rod (6) is matched with the insertion hole (5), a gear (7) is fixed to the other end of the rotating shaft (2), reverse stop teeth (8) are matched with the gear (7) and used for preventing reverse rotating of the gear (7) and the rotating shaft (2), and the rotating shaft (2) and the gear (7) can rotate along with the rotating wheel (4); the rotating shaft bracket (1) is fixedly connected with a left clamping plate (10) and a lower clamping plate (11) together through a connecting plate (9). The line tightening device is simple in structure, convenient to use, and free of damage to the communication line, working efficiency is improved, and labor intensity is relieved.

Description

technical field [0001] The invention belongs to the technical field of electric power system construction tools, in particular to a wire tightening device for erecting communication lines. Background technique [0002] The traditional communication line is erected with a tight line. The staff winds the communication line on the cross-arm tea table. During the operation, multiple people are required to cooperate. The rope is tied to the communication line, and the rope is pulled hard. After repeated adjustments, the required arc can be achieved. Sag, complex operation, time-consuming and labor-intensive, low work efficiency, high labor intensity for operators, and limited by the working environment of the construction site. At present, a wire tensioner for overhead lines is used, although it is easy to operate, but this kind of wire tensioner is equipped with a clamping device, and the communication line is clamped by the clamping device to adjust the tightening, which is eas...

[0002] The traditional communication line is erected with a tight line. The staff winds the communication line on the cross-arm tea table. During the operation, multiple people are required to cooperate. The rope is tied to the communication line, and the rope is pulled hard. After repeated adjustments, the required arc can be achieved. Sag, complex operation, time-consuming and laborious, low work efficiency, high labor intensity for operators, and limited by the working environment of the construction site

At present, a wire tensioner for overhead lines is used, although it is easy to operate, but this kind of wire tensioner is equipped with a clamping device, and the communication line is clamped by the clamping device to adjust the tightening, which is easy to cause damage to the communication line and is uncomfortable. Set up tight lines on communication lines
