Pre-twisted repair strip installation device

Abstract

The invention relates to a preformed armor rod repairing strip installation device which comprises an upper tong arm and a lower tong arm, wherein a lower tong mouth is fixedly connected to the front end of the lower tong arm, a lower clamping trough plate with a semicircular cross section is arranged at the front end of the lower tong mouth, the lower clamping trough plate is detachably connected with the lower tong mouth, the inner wall of one end of the lower clamping trough plate is provided with a semicircular protrusion part, an upper tong mouth is arranged above the lower tong mouth, an upper clamping trough plate matched with the lower clamping trough plate to form a clamping sleeve is arranged at the front end of the upper tong mouth, the upper clamping trough plate is detachably connected with the upper tong mouth, the lower side of the rear end of the upper tong mouth is hinged to the front end of the lower tong arm, the upper side of the rear end of the upper tong mouth is hinged to the front end of the upper tong arm, a movable rod is hinged to the middle of the upper tong arm, the middle of the movable rod protrudes upwards, the lower end of the movable rod is located in the lower tong arm, an adjusting bolt is arranged at the rear end of the lower tong arm, the front end of the adjusting bolt abuts against one end of the movable rod located in the lower tong arm, a pressing rod is hinged to the tail of the upper tong arm, and the front end of the pressing rod is located above the protruding part of the movable rod. The device is simple in structure, capable of facilitating level-fixation of the end of a preformed armor rod repairing strip, and high in working efficiency.

Description

Technical field [0001] The invention relates to a device for installing a pre-twisted wire repair strip. Background technique [0002] In recent years, with the rapid development of society, the external force damage situation faced by transmission line corridors has become more and more severe. When transmission wires are damaged by external forces and are slightly damaged, we generally use pre-twisted wire repair strips for winding repairs, and installation There is no special tool for the repair strip, which mainly depends on the installation skills and work experience of the operator. When the pre-twisted repair strip has a large single wire cross-sectional area, its elastic force is relatively large, which causes the current promotion of "grasp "The process is very laborious, the operation becomes more difficult, and it is difficult for operators with low skills to find the best point of force, and it is easy to fail to use the force; at the same time, the "grasp" process ma...

Problems solved by technology

[0002] In recent years, with the rapid development of society, the situation of external damage to transmission line corridors has become more and more severe. When the transmission wire is damaged by external force and slightly damaged, we generally use pre-twisted wire repair strips for winding repairs, and the installation There is no special tool for the repair strip, and it mainly depends on the installation skills and work experience of the operators. When the cross-sectional area of ​​the single wire of the pre-twisted repair strip is large, its elastic force is relatively large, resulting in the current promotion of "grasp "The process is very strenuous, and the operation becomes more difficult, and it is difficult for unskilled operators to find the best force point, which is prone to failure; at the same time, the "catch" process may cause the end face of the pre-twisted repair strip to be installed Uneven, unable to achieve a perfect repair effect; the end of the pre-twisted wire repair strip is easy to scatter during the "one grasp" operation process, which is prone to falling objects from high altitudes and reduces the safety of electrical work; if the above situation occurs, it will be invisible Increase the time for power outage maintenance and increase the production and operation costs of the enterprise, which can no longer meet the requirements of enterprise development
