Abstract
The invention relates to a rear protection of a dangerous cargo transporting vehicle. The device is provided with a protection fence (1) which is used for protecting the back and the two sides of a vehicle from being impacted, wherein the inner side of the protection fence (1) is fixedly connected with two claw type longitudinal energy absorption parts (2) and two V-shaped horizontal energy absorption parts (4); the two claw type longitudinal energy absorption parts (2) and the two V-shaped horizontal energy absorption parts (4) are respectively mounted on automobile stringers (5), and an X-shaped energy absorption part (3) is fixedly connected among the inner side of the protection fence (1) and the two claw type longitudinal energy absorption parts (2); the protection fence (1) is welded by hollow pipes, and the section of each hollow pipe is in the shape of a rectangle; an inclined angle between the claw type longitudinal energy absorption parts (2) and the V-shaped horizontal energy absorption parts (4) is 90 degrees. Through the adoption of the device, the impact of foreign objects from the back, the sides and the discretionary angle between the back and the sides of the vehicle can be effectively prevented.
Description
Technical field
The invention belongs to mechanical engineering field, is a kind of hazardous material transportation vehicle rear.
Background technology
Hazardous material transportation vehicle rear barrier propterty is poor both at home and abroad at present, while there is traffic accident, is easy to cause goods to reveal, explode and burning.The present invention is solid and reliable, can effectively protect foreign object strike, and protection cargo security, reduces personal casualty and economic loss in traffic accident.
Summary of the invention
Tail protective capacities is poor, easily causes dangerous freight burning and blast, causes larger injures and deaths.In traffic accident, the common rear undercapacity of hazardous material transportation vehicle, side impact and the protective capacities that knocks into the back are poor, easily cause dangerous freight burning and blast, cause larger injures and deaths.
This protective device has two longitudinal absorption cells of pawl type, two horizontal absorption cells of V-type and an X-type absorption cell, and the horizontal absorption cell angle of the longitudinal absorption cell of pawl type and V-type is 90
o, X-type absorption cell, between two longitudinal absorption cells of pawl type, can effectively protect foreign object from arbitrarily angled, the shock of upper and lower to vehicle, thereby protect transport truck goods safety.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is the common rear of hazardous material transportation vehicle.
Accompanying drawing 3 is that finite element method for simulating weight is from the designed device of rear impacts the present invention.
Accompanying drawing 4 is that finite element method for simulating weight is from the common rear of rear impacts hazardous material transportation vehicle.
Accompanying drawing 5 is that finite element method for simulating weight clashes into the designed device of invention from sidepiece.
Accompanying drawing 6 is that finite element method for simulating weight clashes into the common rear of hazardous material transportation vehicle from sidepiece.
figure number explanation
1-guard rail, the longitudinal absorption cell of 2-pawl type, 3-X type absorption cell, the horizontal absorption cell of 4-V type, 5-automobile longitudinal girder,
6-steel tube section size.
The specific embodiment
This hazardous material transportation vehicle rear has guard rail (1), it act as protection vehicle rear and two side impactions, guard rail (1) inner side is fixedly connected with two longitudinal absorption cells of pawl type (2) and two horizontal absorption cells of V-type (4), it is upper that two longitudinal absorption cells of pawl type (2) and two horizontal absorption cells of V-type (4) are arranged on respectively automobile longitudinal girder (5), between guard rail (1) inner side and two longitudinal absorption cells of pawl type (2), is fixedly connected with X-type absorption cell (3);
Guard rail (1) is welded by hollow tubular, and hollow tubular cross section is rectangle;
The longitudinal absorption cell of pawl type (2) and the horizontal absorption cell of V-type (4) angle are 90
o, can effectively protect foreign object from rear portion, sidepiece and between impact at any angle.
Following table is after rear impacts and sidepiece clash into, the designed device maximum deformation quantity contrast of common protective device and the present invention.
| ? | Rear impacts maximum deformation quantity (unit: mm) | Sidepiece clashes into maximum deformation quantity (unit: mm) |
| The designed device of the present invention | 30 | 461 |
| Common rear | 56 | 508 |
| Weight quality: 100kg velocity of impact: 36km/h | ? | ? |
