A simple detachable electric hoisting tool

Abstract

The invention discloses a simple detachable electric hoisting tool, which comprises a connecting part, supporting parts arranged symmetrically at both ends of the connecting part, a lifting part arranged on the connecting part and a winding part arranged on one of the supporting parts. The invention rotates the receiving part to rewind the steel wire rope, so that the return frame moves upward to lift the power cable. At this time, the connecting rod is subjected to a downward pulling force so that the connecting rod will move downward, and when the connecting rod moves downward, the two The support blocks move relatively, so that the slopes of the two support blocks have an upward shoveling force on the wooden plate of the power cable iron frame, and the gravity of the power cable is transferred to the support block to provide an upward shoveling force, so that the power cable It is more labor-saving during hoisting, which reduces the labor level, and when the power cable is hoisted and moved, since the two support blocks are in conflict with the two sides of the wooden plate of the power cable iron frame, the cable can be prevented from shaking when moving.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a simple and detachable power hoisting tool. Background technique [0002] In the daily maintenance work of the power system, power cables are often used, and power cables are super-heavy materials, and they are basically made of iron frames and wooden trays. When moving power cables, they are generally hoisted and moved by cranes or bridge cranes. Operation. [0003] But present hoisting tool is often " Γ " type, and support part is made of main strut, and cantilever suspender. The rotating arm can rotate 360 ​​degrees on the main pole. The power part is composed of a motor (manual winch), a reducer, a clutch, a brake, a rope drum and a wire rope. The electric lifting tool can operate the button starter to realize the forward and reverse rotation of the motor. The steel wire rope can be wound and released, and the lifting operation can be completed by lifting the pulle...

AI Technical Summary

Problems solved by technology

The electric lifting tool can operate the button starter to realize the forward and reverse rotation of the motor. The steel wire rope can be wound and released, and the lifting operation can be completed by lifting the pulley on the bracket part and lowering the object. In this way, the lifting tool has the following disadvantages when using the lifting tool. The structure of the tool is complex. 1. It needs a lot of sub-bar support and reinforcement, and the structural strength is high. The main bar frame and the cross bar bear heavy loads, especially the connection parts, which require high-strength connection and fixing parts. 2. When moving, Since the hoisting part is hoisted by wire ropes, when the ground is uneven and the moving speed is too fast, the power cable will shake, posing a safety hazard. 3. Most of the hoisting tools cannot be disassembled, and the process and steps required for disassembly are relatively Multiple and complicated, not easy to disassemble and assemble, not conducive to transportation and use in different places
