Problems solved by technology

[0002] At present, the hoisting equipment used in China mainly uses electromagnets, which have the disadvantages of large power consumption, poor safety and low work efficiency.
On-site loading and unloading, especially when lifting heavy steel parts, often due to sudden power failure, external voltage reduction, or electromagnet temperature rise causes the suction force to drop, steel will fall off, which can easily cause accidents and affect work progress

Abstract

A magnetic switch type permanent-magnet hoist for heavy load is composed of magnetic pole assembly, magnetic switch is said assembly, and drive mechanism for driving magnetic switch to rotate. The said magnetic pole assembly consists of two magnetic poles, circuit breaking plate between magetic poles, two permanent magnets on their tops, and top cover plate. Said magnetic switch comprises two permanent magnets, non-magnetic blocks installed to their top and bottom, magnetic soft-iron blocks installed to their external sides, and the circuit-short blocks between the said non-magnetic block pair. Its advantages are less electric consumption, high safety and high efficiency.

Description

technical field [0001] The invention relates to a hoisting sling, in particular to a permanent magnet heavy-duty sling with a magnetic switch controlling the conduction or interruption of the magnetic circuit between the magnetic pole and the hanging part, so that the magnetic pole is in the state of absorbing or unloading. Background technique [0002] At present, the hoisting equipment used in China mainly uses electromagnets, which have the disadvantages of high power consumption, poor safety and low work efficiency. On-site loading and unloading, especially lifting heavy steel parts, often due to sudden power failure, external voltage reduction, or electromagnet temperature rise causes the suction to drop, and steel will drop, which can easily cause accidents and affect work progress. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide users with a magnetic switch that saves power, is safe,...
