The Design And The Performance Research About The Neotype Avoiding Roadster Of Buffering Power-absorbing

The inclined shaft is the mine haul pharynx and laryns, playing important role in giving birth to a child in the mine. The high-effect transportation system has importance to coal mine safety at work. Transporting an accident on the grounds of counting is to be next only to second major breakdown of roof accident, roadster accidents among them account for 22.1% of accident transportation. Inclined shaft orbit transports roadster happening like the accident in working regular duty, the frequency roadster accident happened is higher, at the same time because transporting school assignment is common school assignment of many people, that the accident consequence is very grave. Be in progress therefore to coal mine inclined shaft roadster accident taking precautions against effectively very necessary. Attract the energy implement slowing a function down as important component, the person braking in guarding against the roadster device having had direct impact to the effect guarding against roadster. Adopt the energy implement reality braking strong function sucking easy to attract energy effect, to be necessary. The main body of this book major objective is to study one kind of buffer attracts being able to be equipped with, to reduce the loss that the roadster accident brings about.According to attracting the basic being able to be equipped with to buffer, the main body of this book is submitted adopt rubber to attract energy material as buffer. Making use of the resistance which from the trolley rolled on rubber, designed that one kind of repetition usage new model buffer attracts being able to be equipped with but having been used for shaft guards against the roadster device, and carried out theoretical analysis, the dynamic test and the static test about equipped with buffer attracting the energy. Making use of the static test that the omnipotent testing machine carries out get the characteristic property curve of the resistance and displacement According to the different kind rubber material, different rubber structure dimension, different compression amounts, different trolley radius. And get the characteristic property curve that resistance difference with the geometry parameter, the radius compressing amounts, the trolley and rubber characteristic property parameter further. The result indicates that the rubber geometry parameter, the parameter compressing amounts, trolley radius and characteristic property all have to resistance, especially the impact of rubber width and the amounts being compressed over resistance is very heavy. Relation has carried out quantitative analysis on resistance and every further on testing the basis studying between the parameter, has got the resistance calculation formula, has sucked on this account as that kind buffer to be able to be equipped with a parameter designing the calculative. The dynamic test result has verified rubber slowing the change law attracting the braking retarded velocity being able to be equipped with down assuming the ladder form, development buffer has attracted energy effect and static state test result has been consistent.Take some working condition as example, adopt above-mentioned resistance to calculate formula sucking to rubber buffer being able to be equipped with structure having carried out design secretly scheming against. The result is indicated that owes rubber buffer to suck to be able to be equipped with may attract energy effect to very good buffer up in guarding against roadster braking process in the inclined shaft, and this device has but the design repeating usage, slowing stable adjustable system driving force characteristic property down, and may be in progress according to need ascertains that, and have the fairly good application prospect.
