Abstract
A safety protective device of a dangerous cargo groove tank solves the problem that a dangerous cargo groove tank in the prior art is provided with no tank safety protective device. The safety protective device of the dangerous cargo groove tank is provided with an arch-face anti-collision frame which is formed by an upright column, an arc-shaped beam and a short connecting column. A pair of triangle frames is arranged in front of the anti-collision frame and is respectively arranged at two sides of the groove tank. A supporting beam is arranged at the tops of the triangle frames and connects the triangle frames at the two sides of the groove tank into a whole. An upper portion supporting rod and a middle portion supporting rod are arranged between the triangle frames and the anti-collision frame and are used for transferring collision force. The safety protective device of the dangerous cargo groove tank is formed by the anti-collision frame, the triangle frames, the supporting beam and the supporting rods. The safety protective device of the dangerous cargo groove tank has the advantages that the triangle frames of the anti-collision frame is arranged behind a tank body of the dangerous cargo groove tank, other vehicles are prevented from directly colliding the tank body when a traffic accident occurs, the tank body is prevented from leaking, damage of the tank body of the groove tank can be effectively avoided, mass death and casualty accident is avoided, and unnecessary corrosion, poison and pollution are prevented from being caused.
Description
Technical field
The utility model belongs to a kind of vehicle protection device, particularly a kind of inflammable, easy sudden and violent, perishable, hypertoxic dangerous material groove tank car safety device for road transport.
Background technology
Along with the sustainable development of economy, China's vehicle possess amount rapid growth, Road Transportation is day by day busy.Because it is inharmonious that people, car, road are developed, the deep-seated problems that traffic administration work exists also display gradually, and particularly from the beginning of this year, frequent accidents occurs, and have caused heavy losses for the country and people masses' the security of the lives and property.
In recent years, 615 dangerous material groove tank car over-the-road transportation accidents have been put in the authoritative department investigation in order, behind the statistical analysis, draw reason, ratio, time and form distribution that dangerous material groove tank car over-the-road transportation accident occurs, determined the leakage probability of different accident tank bodies and different category of roads accidents.The analysis showed that, in the accident that occurs, human factor accounts for 67%, and roll-over accident is main accident type, and two car rear-end collisions and low-grade highway accident leakage probability are the highest, are respectively 84.52% and 82.7%, and be the high incidence period of accident night.
In recent years, the groove tank car frequent accidents of peril of transportation product occurs, morning on August 26th, 2012, the luxuriant express highway generation of the bag Accident that Shaanxi Province's Yan’an is domestic, a two-deck berth carriage and the groove tank car that methyl alcohol is housed knock into the back, and cause the leakage of methyl alcohol groove tank car, and two cars are on fire, accident causes 36 people dead, only 3 people escape.Only in three days, the accident that a lorry and truck tanker knock into the back occurs again toward Longyan direction in dragon high speed ZhangZhou, Zhang, Fujian, causes teamster to die instantly.The road traffic accident that this year, " 629 " Guangzhou occured also is that truck tanker is knocked into the back, and causes solvent naphtha to be revealed causing detonation, accident to cause that 20 people are dead, 31 people are injured.
Along with economic development, the demand of road transport dangerous material and freight volume are at increase year after year.A investigation demonstration, the annual over-the-road transportation dangerous freight of China was about 200,000,000 tons in recent years, and wherein cyanide just reaches the hundreds of thousands of ton, and inflammable and explosive oil product reaches 100,000,000 tons.The supervision problem of these hazardous materials transportations of how to do well seems particularly outstanding, and these accidents are beaten the alarm bell in the hazardous materials transportation supervision again.
Historical lessons show, when road traffic accident occured, if dangerous material groove tank car is not revealed, then accident was in the controollable scope.If dangerous material groove tank car is revealed, will cause major traffic accidents, cause the great person and property damage.And there is no at present the safety device of tank body on the dangerous material groove tank car of China, colliding, overturning, turning on one's side or during by other vehicle rear-end collision, be easy to cause the damage of groove tank car tank body, cause dangerous material to be revealed, thereby lead to the major traffic accidents of car crash.
Summary of the invention
The technical problems to be solved in the utility model is, overcoming existing dangerous material groove tank car does not have the problem of tank body safety device, a kind of dangerous material groove tank car safety device is provided, colliding, overturning, turning on one's side or during by other vehicle rear-end collision, prevent that the tank body breakage from appearring in dangerous material groove tank car, liquid flows out, and avoids being poisoned and the dead group of group that causes hinders accident and occurs by fire, blast, pollution, burn into.
The utility model has the bumper frame of a cambered surface, bumper frame is made of column, arc crossbeam and short joint pin, also has a pair of spider in the place ahead of bumper frame, spider is separately positioned on the both sides of groove tank car, a supporting traverse is arranged at the top of spider, the spider of groove tank car both sides is linked together, between bumper frame and spider, also have upper support bar and middle part strut bar, be used for transmitting impact, bumper frame, spider, supporting traverse and strut bar consist of the safety device of dangerous material groove tank car.
Also be provided with energy absorbing component between spider and vehicle frame girder steel, described energy absorbing component is spring, hydraulic actuating cylinder or friction plate.
Described spider is a pair of or two pairs, according to grade single choice or the combination configuration of peril of transportation product groove tank car.
Also have several rubber fenders in the inboard of spider, when avoiding the rollover of groove tank car tank body is caused damage.
The utility model has the advantage of:
1; tank body rear at dangerous material groove tank car arranges bumper frame; when accident; avoid other vehicles directly to collide tank body; prevent that tank body from revealing; bumper frame is cambered surface; both improved the intensity of bumper frame itself; when colliding, play again the effect of the power of letting out; the place ahead in bumper frame arranges spider; and use; the middle part strut bar connects; both bumper frame was played the effect of supporting of reinforcing; simultaneously; again tank body is played the safety guard-safeguard effect; when the power actuated vehicle of back reason whatsoever; clash with the groove tank car of peril of transportation product or when knocking into the back; bumper frame is at first blocked errant vehicle; impulsive contact force passes to strut bar by bumper frame; pass to again spider; spider connects mutually with energy absorbing component; most of impulsive contact force will be by energy absorbing component and just structural deformation and conflict or the resistance that two cars slide forward after knocking into the back absorb, can play safety protection function by actv. to the groove tank car of peril of transportation product, when having an accident; the tank body that can effectively prevent the groove tank car is damaged, avoids the dead group of group to hinder the accident generation and cause unnecessary corrosion; poison and pollution.
2, in the inboard of spider rubber fender is set, tank body is played the safety guard-safeguard effect, tank body occurs damaged when having avoided rollover or being subject to side impact.
3, scientific structure, rationally, simple, cost is low, is easy to newly make the installation of vehicle and the transformation of existing vehicle.
