Abstract

A kind of vehicle transport dangerous goods rear, there is guard rail (1), it act as protecting vehicle rear and two side impactions, guard rail (1) inner side is fixing connects two claw type longitudinal direction absorption cell (2) and two the horizontal absorption cell of V-types (4), two claw type longitudinal direction absorption cell (2) and two the horizontal absorption cell of V-types (4) are separately mounted on automobile longitudinal girder (5), fixing connection X-type absorption cell (3) between guard rail (1) inner side and two claw type longitudinal direction absorption cell (2)；Guard rail (1) is welded by hollow pipe, and hollow pipe cross section is rectangle；Claw type longitudinal direction absorption cell (2) and V-type horizontal absorption cell (4) angle are 90o, can effectively protect foreign object from rear portion, sidepiece and between impact at any angle.

Description

Vehicle transport dangerous goods rear
Technical field
The invention belongs to mechanical engineering field, be a kind of vehicle transport dangerous goods rear.
Background technology
Vehicle transport dangerous goods rear barrier propterty is poor the most both at home and abroad, when there is vehicle accident, it is easy to cause goods to reveal, explode and burn.The present invention is solid and reliable, it is possible to effectively protect foreign object strike, protects cargo security, reduces casualties and economic loss in vehicle accident.
Summary of the invention
Tail protective capacities is poor, is easily caused hazardous cargo burning and blast, causes bigger injures and deaths.In vehicle accident, vehicle transport dangerous goods common rear intensity deficiency, side impact and the protective capacities that knocks into the back are poor, are easily caused hazardous cargo burning and blast, cause bigger injures and deaths.
It is 90 that this preventer has two claw type longitudinal direction absorption cells, two horizontal absorption cells of V-type and an X-type absorption cell, claw type longitudinal direction absorption cell and V-type horizontal absorption cell angleo, X-type absorption cell, between two claw type longitudinal direction absorption cells, can effectively protect foreign object from shock arbitrarily angled, that upper and lower is to vehicle, thus protect transport truck goods safety.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the common rear of vehicle transport dangerous goods.
Accompanying drawing 3 for finite element method for simulating weight from device designed by the rear impacts present invention.
Accompanying drawing 4 is that finite element method for simulating weight is from the common rear of rear impacts vehicle transport dangerous goods.
Accompanying drawing 5 is that finite element method for simulating weight is from the designed device of side impact invention.
Accompanying drawing 6 is that finite element method for simulating weight is from the common rear of side impact vehicle transport dangerous goods.
Figure number explanation
1-guard rail, 2-claw type longitudinal direction absorption cell, 3-X type absorption cell, the horizontal absorption cell of 4-V type, 5-automobile longitudinal girder,
6-steel tube section size.
Detailed description of the invention
This vehicle transport dangerous goods rear has guard rail (1), it act as protecting vehicle rear and two side impactions, guard rail (1) inner side is fixing connects two claw type longitudinal direction absorption cell (2) and two the horizontal absorption cell of V-types (4), two claw type longitudinal direction absorption cell (2) and two the horizontal absorption cell of V-types (4) are separately mounted on automobile longitudinal girder (5), fixing connection X-type absorption cell (3) between guard rail (1) inner side and two claw type longitudinal direction absorption cell (2)；
Guard rail (1) is welded by hollow pipe, and hollow pipe cross section is rectangle；
Claw type longitudinal direction absorption cell (2) and V-type horizontal absorption cell (4) angle are 90o, can effectively protect foreign object from rear portion, sidepiece and between impact at any angle.
After following table is rear impacts and side impact, device maximum deformation quantity contrast designed by common preventer and the present invention.
Rear impacts maximum deformation quantity (unit: mm) Side impact maximum deformation quantity (unit: mm)
Device designed by the present invention 30 461
Common rear 56 508
Weight quality: 100kg stroke speed: 36km/h
