Safety winch for crane

Abstract

The invention relates to the technical field of mechanical engineering, in particular to a safety winch for a crane, which includes a take-up wheel, a first fixing frame and a swing rod, a motor is provided at the front end of the take-up wheel, and a fixed rear end of the take-up wheel A brake device is connected, and the brake device includes a brake caliper body, a piston, a rubber ring, a friction block, an oil inlet pipe and a brake disc, and a brake caliper body is provided inside the brake device, and the brake caliper body is slidingly connected There is a piston, and the rubber ring is connected outside the piston. In the present invention, through the two brake caliper bodies, one is used as a normal brake and the other is used as an emergency brake. When the normal brake fails, the emergency brake is activated. It can not only ensure that the work efficiency is not affected, but also improve the safety of the working environment. This kind of design concept is novel, scientific in design, has huge economic benefits and broad market prospects, and is worth popularizing and using.

Description

Technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a safety winch for cranes. Background technique [0002] A winch is a winch with a vertically installed cable drum. It can wind up but does not store ropes under power. It also refers to a winch with a rotation axis perpendicular to the deck. It is a self-protection and traction device for vehicles and ships. It can be used under other conditions. It is an indispensable safety device for military and police, petroleum, hydrology, environmental protection, forestry, transportation, public security, border defense, fire protection and other outdoor sports for operations such as clearing obstacles, dragging objects, and installing facilities. Therefore, it is safe for a crane The demand for winches is increasing. [0003] The structure of most safety winches for cranes currently on the market is too unitary, they only serve as stranding, and cannot measure the height and ar...

AI Technical Summary

Problems solved by technology

[0003] Most of the safety winches for cranes currently on the market have a single structure, which only plays the role of twisting wires, and cannot measure the height and arrange the functions of steel cables; most of the crane winches do not have safety functions, or safety functions It is not sound, can not measure the quality of heavy objects, and has no ability to deal with accidents, etc. Therefore, a safety winch for cranes is proposed to solve the above problems
