Ejector with arc vertical line

Abstract

The invention relates to an ejector with an arc vertical line, which is used for solving the problem the vertical line directly manually thrown and hung is adopted in the running of the traditional high-voltage power transmission line to cause high hazard, poor precision and high difficulty in the throwing and ejecting processes. The ejector with a vertical line comprises a guide steel pipe whichis internally or externally provided with an elasticity storage mechanism and an elasticity ejecting mechanism matched with the elasticity storage mechanism; an ejecting head in the elasticity storage mechanism is in sliding fit with the guide steel pipe; the ejector with a vertical line, which is matched with the ejecting head, has the degree of freedom for sliding along the guide steel pipe andis arranged in the guide steel pipe to form collision combination with the ejecting head. The ejector is manufactured by adopting a mechanical elasticity theory and has simple structure and high practicability.

Description

technical field [0001] The invention belongs to a stringing tool in the construction of high-voltage line erection, and specifically refers to a sag line ejector which ejects a sag line ejection block. Background technique [0002] During the operation of high-voltage transmission lines, it is always necessary to have direct contact with the wires, such as live testing, live defect elimination and equipotential work, etc. At this time, it is necessary to use sag lines to assist the work. The way of the line is that the operator throws it directly by hand. Since the strength and direction of the manual throwing are only based on the operator's feel, it is difficult to control, and it is difficult to guarantee the efficiency of the work and the personal safety of other cooperating personnel. In recent years, with the increase of voltage With the continuous improvement of grades, as well as the continuous adoption of double-circuit high-voltage transmission lines on the same to...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problems of high risk, poor accuracy and great difficulty in the process of using manual direct throwing with vertical lines in the operation of high-voltage transmission lines

It solves the practical problem that the task cannot be completed due to insufficient strength of the vertical line for manual throwing in the process of safe production; the ejection force of the catapult with the vertical line can be controlled according to the needs of the ejection height
