Lift equipment rapid protecting device

Abstract

A quick protective device for a piece of lifting equipment consists of a pulley 2, a clamp plate 3, a wheel shaft 4, a guide bar 5, a load limit compression spring 6, an overload alarm system 7, a guide bar seat 8, a pull rope 9, a fixed support 10, a tension spring 11, a moveable pin 12, a pulley 11, a guide rail 15, a slide way 16, a handing bracket 17 shaped like the Chinese character 'Men', a lifting basket beam 18 and a moveable pin slide seat 19. The invention helps a lifting basket of the lifting equipment to move up and down along the guide rail without running off the rail, and limits two vertical posts to expand externally and bend, to play the role of middle supporting, so as to improve the overall stability of the lifting equipment and effectively protect the equipment. The invention can also give alarm when the lifting equipment is overloaded and make quick response when a cable is broken, so as to effectively prevent the goods from damage and the people from injury accidents.

Description

technical field [0001] The invention relates to a lifting device, in particular to a safety protection device for a material lifting device. Background technique [0002] Existing material hoisting equipment such as hoists, the rope breakage protection device responds slowly, and generally takes 1 to 3 seconds to respond, and the basket cannot be quickly locked after the rope breaks, so the basket falls frequently. And there is no overload alarm facility, accidents are very easy to happen. The overweight of the hoist is an important reason for the accident of the hoisting equipment. It is a common phenomenon for the material hoisting equipment to go off the track. In addition, the pulley system of the basket is connected by four short steel wire ropes, so the basket shakes greatly and is not stable during operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a quick protection device for lifting equipment,...
