Abstract
The utility model discloses a buffer of a crane cart. The buffer comprises a back connector, wherein the back connector comprises a steel plate and a connection rod which is fixedly connected with the back part of the steel plate; the front part of the connector is provided with a square elastic buffering block made from polyurethane, a plurality of spring assemblies are arranged in the elastic buffering block, each spring assembly comprises a middle spring, a front rod is arranged in front of the spring, a back rod is arranged behind the spring, the end part of the back rod is connected with the steel plate of the back part connector, and the front rod is connected with a buffering head which is arranged at the front end of an elastic buffering clamp. The buffer disclosed by the utility model serves as an anti-collision buffering device with energy absorption and shock buffering effects, and is firm in integral structure and strong in safety; due to the elastic buffering block, the polyurethane buffering block can be protected; and simultaneously, the steel plate is provided with four through holes so as not to influence the work performance and service life of the buffering block, therefore, the buffer disclosed by the utility model has the advantages of good buffering effect and long service life.
Description
Technical field
The utility model relates to a kind of cart energy disperser, specifically relates to a kind of cart energy disperser that is used for hoisting crane, belongs to mechanical field.
Background technology
At present, the hoisting crane energy disperser is an important safety protective device on the elevator machinery, and the existing kind that is used for the safety device on the elevator machinery is a lot, and spring bumper, rubber draft gear, polyurethane bumper absorber, water bumper etc. are arranged.In recent years, polyurethane bumper absorber was owing to its excellent performance, easy for installation, simple in structure being widely used.Yet because its structural reason, existing energy disperser is only limited under normal environment works; In some special occasions; As use with spring bumper or its effect of under hot environment, working relatively poor, moreover also solid inadequately, safety is relatively poor; That is to say existing hoisting crane energy disperser because its integral structure lacks bracing means, so its energy-absorbing damping, high temperature resistant and safety is relatively poor.
The utility model content
To the deficiency that prior art exists, the utility model technical matters to be solved is, a kind of crane energy disperser is provided, and integral structure is firm, has energy-absorbing damping and resistant to elevated temperatures characteristics, and structure is tight, it is convenient to install, and cost is low.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of crane energy disperser comprises the rear portion adaptor union, and its rear portion adaptor union comprises the pipe link that steel plate is captiveed joint with the steel plate rear portion; Said adaptor union front portion is provided with the elastic buffer piece that polyurethane is processed; The elastic buffer piece is square, and elastic buffer piece set inside has some spring assemblies, and spring assembly comprises the spring at middle part; The spring front portion is provided with preceding bar; The spring rear portion is provided with the back bar, and the end of back bar connects the steel plate of rear portion adaptor union, and preceding bar is connected in the buffer head of elastic buffer piece front end; Said buffer head is cylindrical, and the rear portion is provided with a circular groove, and circular groove inside is stretched in the end of preceding bar.
Optimize, above-mentioned crane energy disperser, its steel plate are provided with four through holes, and four through holes are arranged at four jiaos of steel plate.
Optimize, above-mentioned crane energy disperser, its buffer head are that rubber is made the flexible shock strut of buffer head set inside.
Optimize, above-mentioned crane energy disperser, the fixing welding of its pipe link and steel plate, pipe link is outside equipped with filled rubber.
The utlity model has the crashproof shock absorber of energy-absorbing damping effect, integral structure is firm, high safety; Because the existence of flexible bump rubber; So can play protective effect to the polyurethane buffering piece; Simultaneously because steel plate is provided with four through holes; So do not influence the serviceability of bump rubber and the service life of bump rubber, so the energy disperser of the utility model has the advantage of good buffer effect, high life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of crane energy disperser, comprises rear portion adaptor union 1, and its rear portion adaptor union 1 comprises the pipe link 12 that steel plate 11 is captiveed joint with steel plate 11 rear portions; Said adaptor union 1 front portion is provided with the elastic buffer piece 2 that polyurethane is processed; Elastic buffer piece 2 is square, and elastic buffer piece 2 set inside have some spring assemblies 3, and spring assembly 3 comprises the spring 31 at middle part; Spring 31 front portions are provided with preceding bar 32; Spring 31 rear portions are provided with back bar 33, and the end of back bar 33 connects the steel plate of rear portion adaptor union 1, and preceding bar 32 is connected in the buffer head 4 of elastic buffer piece 2 front ends; Said buffer head 4 is cylindrical, and the rear portion is provided with a circular groove 41, and circular groove 41 inside are stretched in the end of preceding bar 32.Steel plate 11 is provided with 13, four through holes 13 of four through holes and is arranged at four jiaos of steel plate 11.Buffer head 4 is made the flexible shock strut 42 of buffer head 4 set inside for rubber.Pipe link 12 and steel plate 11 fixing welding, pipe link 11 is outside equipped with filled rubber 14.
The utlity model has the crashproof shock absorber of energy-absorbing damping effect, integral structure is firm, high safety; Because the existence of flexible bump rubber; So can play protective effect to the polyurethane buffering piece; Simultaneously because steel plate is provided with four through holes; So do not influence the serviceability of bump rubber and the service life of bump rubber, so the energy disperser of the utility model has the advantage of good buffer effect, high life.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
