Portable electric high-voltage line operation throwing-hanging catapult

Abstract

The invention brings forward a portable electric high-voltage line operation throwing-hanging catapult comprising a catapult body with a hollow structure. One end of a cavity in the catapult body is provided with an energy storage spring. The other end of the energy storage spring is connected with an emission block. An emission block handle of the emission block stretches out of a top window of the upper surface of the catapult body. A clamping block is hinged on the catapult body below the energy storage spring, and the clamping block is connected with a trigger. The other end of the cavity in the catapult body is provided with a plumb handle, and the external end part of the plumb handle is provided with a plumb. The plumb handle is connected with a pulling handle. The pulling handle and the emission block handle are connected via a connecting rib. A line-winding wheel is arranged outside the catapult body below the plumb handle, and winding lines on the line-winding wheel are connected with the plumb. The catapult is convenient to operate, and catapulting angle, distance and height of the plumb are easy to control so that a rope ladder can be rapidly hung and thus the catapult is safe and reliable.

Description

technical field [0001] The invention relates to a catapult, in particular to a portable power high-voltage line operation throwing catapult. Background technique [0002] At present, the iron towers of high-voltage power lines are constantly rising, and the high-altitude operations of the lines generally require the suspension of soft ladders. The traditional suspension of soft ladders for power high-voltage line operations is to use manpower to wrap heavy objects with soft ropes and throw them over the high-voltage lines for suspension. Due to the use of manual throwing, the throwing force and direction need to be felt by the throwing personnel. It is difficult to control the actual operation, and it is even more difficult to ensure the safety and work efficiency of the staff. Some catapults are used for throwing and hanging during the operation of the existing electric high-voltage lines. However, most of these catapults are powerful, have a high ejection height, and are i...

AI Technical Summary

Problems solved by technology

Due to the use of manual throwing, the throwing force and direction need to be felt by the throwing personnel. It is difficult to control the actual operation, and it is even more difficult to ensure the safety and work efficiency of the staff.

The existing high-voltage power lines use catapults for throwing and hanging. However, most of these catapults are powerful, have a high ejection height, and are inconvenient to carry, which affects normal use.
