Problems solved by technology

[0002] Existing material hoisting equipment such as hoists, the response of the broken rope protection device is slow, and it usually takes 1 to 3 seconds to respond. After the rope is broken, the basket cannot be locked quickly, 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, and the basket shakes greatly during operation and is not stable

Embodiment Construction

[0015] The fast protection device for hoisting equipment in this embodiment, see Figures 1-4, from top to bottom is the steel wire rope 1, pulley 2, splint 3, wheel shaft 4, guide rod 5, load-limiting compression spring 6, overload alarm 7 of the hoisting equipment , guide bar seat 8, fixed support 10, stay cord 9, pulley 13, extension spring 11, door font hang bracket 17, movable pin 12, movable pin sliding seat 19. When the hoisting equipment is in normal operation, the wire rope 1 of the hoisting equipment pulls the pulley 2, splint 3, wheel shaft 4, and guide rod 5 upward with an upward pulling force, and the two load-limiting compression springs 6 installed at the lower end of the guide rod 5 are compressed. The two stay ropes 9 connected to the lower end of the guide rod 5 are pulled upwards, and the two door-shaped hanging brackets 17 and the movable pin 12 are drawn to the predetermined retracted position by the stay ropes 9 through the pulley 13, and are connected to t...

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,...
