Simple and detachable electric power hoisting tool

Abstract

The invention discloses a simple and detachable electric power hoisting tool. The simple and detachable electric power hoisting tool comprises a cross arm. Supporting frames are arranged at the two ends of the cross arm. Two fixed pulleys are installed on the cross arm through an installation frame. The simple and detachable electric power hoisting tool further comprises a hoisting frame. A hoisting hook is fixedly arranged at the lower end of the hoisting frame. A movable pulley is installed on the hoisting frame. A steel wire rope wound on the movable pulley and the fixed pulleys is connected to the upper end of the hoisting frame. The supporting frames comprise sliding sleeves which are arranged at the two ends of the cross arm in a sleeving mode. Main supporting arms are perpendicularly and fixedly arranged in the middle portions of the sliding sleeves. Auxiliary supporting arms are coaxially hinged to the sliding sleeves. An adjustment mechanism which can be used for adjusting and fixing the included angle between each main supporting arm and the auxiliary supporting arm is arranged between the main supporting arm and the auxiliary supporting arm. Wire winding mechanisms which are connected with the tail ends of the steel wire rope are installed on the supporting frames. Universal wheels with self-locking functions are installed at the bottoms of the main supporting arms and the auxiliary supporting arms. The simple and detachable electric power hoisting tool has the beneficial effects that assembly is convenient and rapid, hoisting is effortless and stable, movement is convenient, the occupied space is small after the hoisting tool is detached, transportation is convenient, and the simple and detachable electric power hoisting tool is particularly suitable for field working of an electric power system.

Description

technical field [0001] The invention relates to a simple and detachable electric hoisting tool. Background technique [0002] When the power system installs and debugs equipment or maintains in the field, a hoist is often used to transport the equipment. Lifting machine is divided into rotary arm type lifting machine, straight type lifting machine, full-angle type. Practical small hoist, straight slide hoist, small hoist, small hoist, portable hoist, micro hoist, micro hoist, electric hoist, indoor hoist, portable hoist is born The new product at the beginning of the century is a major breakthrough in the mechanical transportation of materials in the construction and decoration industry today. It is suitable for the lifting of high-rise buildings, such as various building materials and various decoration materials, especially for corridors that are inconvenient to carry. Long and wide materials such as planks and wood boards have their unique advantages. From then on, the...

AI Technical Summary

Problems solved by technology

[0005] ①The structure of the tool is complex and requires a lot of auxiliary rod support and reinforcement

[0006] ② The structural strength requirements are high, and the main pole frame and the crossbar bear heavy objects, especially the connection parts, which require high-strength connection and fixing parts

[0007] ③It must be fixed in a certain place and cannot be moved. Even if it can move, it is limited to the 360-degree range of the main pole, which is relatively inflexible and poor in practicability

[0008] ④ Most of them cannot be disassembled, and those that can be disassembled require more and more complicated steps, are not easy to disassemble and assemble, and are not conducive to transportation and use in different places
