Abstract
The utility model relates to folding crushing device, which is mounted on a rear draft lug of a locomotive and is engaged with a coupler and draft gear. The folding crushing device comprises a bottom plate and two crushing units, a base is fixedly mounted on the bottom plate, each crushing unit is composed of at least one crushing tube, and one end of each crushing tube is equipped with a crushing tube connector while the other end is fixedly mounted on the base. The utility model is simple in structure, convenient in changing after having actions and small in occupied mounting space after connecting a plurality of crushing tubes in parallel, has extremely high capacity, is high in energy absorption and is adaptable to hypervelocity impact.
Description
Technical field
The utility model relates to a kind of rolling stock fender guard, specifically, relates to a kind of conquassation device of rolling stock being implemented protection under impact of railway locomotive hypervelocity or accident condition.
Background technology
In the transportation of rolling stock and high-power locomotive, being in operation sometimes to result from unimaginable collision.Therefore, in order to protect the bus attendant that in transportation, carries on the vehicle and passenger's safety, exist an a kind of part that makes vehicle actively distortion come endergonic notion.Promptly under impact of locomotive hypervelocity or accident condition,, need a kind of conquassation device that can absorb big energy for crew member and the passenger who protects carrying.This conquassation device produces action and has absorbed big energy when impact or accident, reaches the purpose of protecting beyond the vehicle enforcement.At present, the conquassation device that existing vehicle uses mainly is an expanding conquassation device, and promptly by convergent divergent channel expansion energy-absorbing, still, this Unit Installation space is big, and is mainly used in the railcar, is not suitable on the high-power locomotive.
The utility model content
The purpose of this utility model is the deficiency that exists at conquassation device in the existing rolling stock, provide a kind of installing space little, absorb the big collapsible conquassation device of energy.
The technical solution of the utility model is: a kind of collapsible conquassation device, and described conquassation device is installed on the locomotive rear draft lug, and matches with coupler buffering device; This conquassation device comprises base plate and two conquassation unit, is fixed with a base on the base plate, and described conquassation unit is made up of at least one conquassation pipe, and an end of conquassation pipe is provided with the conquassation pipe connector, and the other end is packed on the base;
Preferably, described conquassation unit is made up of two conquassation pipes;
Preferably, parallel with one anotherly between the described conquassation pipe be packed on the base by locating dowel pin, the conquassation pipe connector is packed on the mounting groove of locomotive rear draft lug by bolt;
Preferably, described base plate cooperates with the energy disperser baseplane.
The beneficial effects of the utility model are: the utility model is simple in structure, produces the action back and changes conveniently; And adopt the parallel connection of a plurality of conquassation pipe, the installing space that takies is little, when the conquassation pipe produces action, has very high capacity, and it is big to absorb energy, is applicable to the hypervelocity impact.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model specific embodiment;
Accompanying drawing 2 is the lateral plan of the utility model specific embodiment structure;
Accompanying drawing 3 is the utility model mounting structure scheme drawing.
The specific embodiment
Specific embodiment as shown in Figures 1 to 3: a kind of collapsible conquassation device, described conquassation device is installed on the locomotive rear draft lug 1, and match with coupler buffering device, this conquassation device comprises base plate 2 and two conquassation unit, base plate 2 matches with the bottom surface of energy disperser 7, is fixed with a base 3 on the base plate 2.The conquassation unit is made up of two conquassation pipes 4, and an end of conquassation pipe 4 is provided with conquassation pipe connector 5, and the other end is packed on the base 3; Parallel with one anotherly between the conquassation pipe 4 be packed on the base 3 by locating dowel pin 6, conquassation pipe connector 3 is packed on the mounting groove of locomotive rear draft lug 1 by bolt.
Under impact of locomotive hypervelocity or accident condition, hitch 8 drives energy dispersers 7 and moves, and promotes the collapsible distortion of conquassation pipe 4 generations and absorbs energy.
