Abstract
The invention relates to a rigid train front end anticreeper which comprises a draw gear box and an anti-creep device which are arranged on the back of an end beam. A through hole for the anti-creep device to pass through is formed on the end beam. The anti-creep device comprises anti-creep teeth, a supporting base and a base, wherein the anti-creep teeth, the supporting base and the base are sequentially connected. The rear portion of the base of the anti-creep device penetrates through the through hole and then is connected on the draw gear box, and is fixed with the end beam through fasteners. Because the anticreeper is of a rigid structure and free of a bumper, and the base and the draw gear box are connected in a welding mode, the anticreeper is strong in rigidity and can not easily deflect under impact. Furthermore, the anti-creep device is connected with the end beam through bolts, the anticrepper is easy to replace in the real use process.
Description
Technical field
The present invention relates to a kind of train anti-creeper, be specifically related to a kind of rigidity anti-creeper that is arranged on the train front end.
Background technology
Along with continuous progress and the development of track traffic technology, the collision safety problem has become a focus of guideway vehicle design study as the important component part in the modern vehicle design.
Understand according to the contriver, in train collision accident in the past, passive security aspect consideration is seldom particularly climbed the car accident, can bring very serious consequence.It is the Chinese patent of CN 202243517 as Granted publication, a kind of anti-creeper is disclosed, the contriver is finding in a large amount of tests to this anti-creeper: although use this anti-creeper to climb the possibility of car after can reduction train collision to a certain degree, alleviate the harm that causes after collision case occurs.But because itself structural rigidity is not strong, so be difficult to guarantee that it does not occur crooked (is not namely straight standing upright towards the train working direction under collision situation complicated and changeable under impact force action, and to the train both sides or above-below direction crooked), just can not provide good anti-creep function after it is crooked.
And existing train front end is impacting easily distortion, and structural strength is inadequate.
Therefore develop a kind of anti-creeper that has the train front end of stronger rigidity or have a stronger rigidity and become the problem that need solve.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of train front end rigidity anti-creeper that is difficult for diagonal distortion under thump.
the present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of train front end rigidity anti-creeper, comprise anti-creep device and the coupler pocket of being located at train end beam of underframe thereof rear, the described coupler pocket left and right sides and vehicle body bottom frame side bar welding are fixed, have the through hole that passes through for anti-creep device on described end carriage, described anti-creep device comprises the anti-climbing tooth that is connected successively, supporting seat and base, described anti-climbing tooth is by spaced apart polylith horizontal plate vertically, and the stay bearing plate that is fixed in the horizontal plate rear end consists of, described horizontal plate and stay bearing plate are the Integral rigid structure, described supporting seat comprises involutory upper, lower U-shaped lid and insert-connecting plate, on described, lower U-shaped covers equal corresponding interval and has strip-shaped clamp groove, described insert-connecting plate is plugged in described strip-shaped clamp groove accordingly, described base is the rigid cartridge that two ends are provided with connecting strap, after passing described through hole, the base rear portion of described anti-creep device is connected on described coupler pocket.
Further, offer a plurality of screws on described connecting strap, described supporting seat is connected by the connecting strap of bolt with described base front end.
In order further to improve the rigidity of anti-creeper in the present invention, the through hole that has on described end carriage is two, and the distance at the described end carriage of distance two ends is 1/4 of end carriage length respectively.
Further, be connected to welding between described base and described coupler pocket.
Further, described coupler pocket comprises with described side bar and forms first, second web connected vertically, the top of described first, second web is connected with upper cover plate, is connected with dividing plate between described first, second web, and the bottom of described first, second web is connected with base plate.
The invention has the beneficial effects as follows:
In the present invention, anti-creeper is rigid construction, is not with energy disperser, connects with welding manner between base and coupler seat, rigidity is strong, be difficult for occuring under impacting crooked, and, anti-creep device is connected bolt to connect with base, and anti-creep device is easy to change in the use procedure of reality.The manufacturing of this structure is simple, easy for installation with respect to anti-creeper in the past, and cost is low, and is practical, and good application prospect is arranged in car body design afterwards.
