Abstract
The invention discloses an anticreeper for a rail car. The anticreeper is characterized in that an anti-creeping structure in which a guiding part is added is adopted, so as to lead the knock of a car body to occur in the front of the horizontal direction, an impact is formed from the front so as to prevent the car from producing serious consequences such as creeping, overturning and the like. The anticreeper comprises an anti-creeping part and a guiding part which are connected mutually, wherein anti-creeping teeth are formed at the front end of the anti-creeping part, and the guiding part is tightly installed on the end part of the car body; buffer energy-absorbing components are filled in the interiors of the anti-creeping part and the guiding part; the anti-creeping part and the guiding part are respectively provided with a box type whole structure which is formed by welding steel plates and has an opening end; and the size of the outer outline of the anti-creeping part is smaller than that of the guiding part, and the anti-creeping part and the guiding part are oppositely subjected to splicing and assembly, and are transversely fixed through shear pins arranged at the side. The anti-creeping part and the guiding part are oppositely subjected to splicing and assembly, and the guiding part provides the movement track generated by the fact that the anti-creeping part is extruded and retreated when absorbing impact energy which is generated when the car is clashed.
Description
Technical field
The present invention relates to a kind of anti-creeper of using when bump takes place guideway vehicle of being applied to, belong to mechanical manufacturing field.
Background technology
The speed per hour of present domestic guideway vehicle has reached 380 kilometers/hour velocity stages, and the considerable damage that causes for body construction when taking place to clash into each other for reducing guideway vehicle is provided with safety devices such as anti-creeper usually between car body end, vehicle.
The purpose of design, use anti-creeper is; Can when taking place to clash into each other, be meshing with each other by anti-climbing tooth; Carry out frontal impact between the car body and make the car body end deform to absorb the huge impact energy; And then prevent that vehicle from producing and climb folded, serious consequence such as topple, loss such as avoid causing casualties.
The anti-creeper that existing domestic guideway vehicle uses; Adopt the structure and the connection mode of steel plate welding at large; If the structural rigidity of this type of anti-creeper is too high; Then can when vehicle clash into each other, impulsive force only passed to underframe and reduce area of thrust surface, thereby can't all absorb impact energy, vehicle be prone to rollover or topples.If the structural rigidity of anti-creeper is low excessively, be vulnerable to the negative function of vertical load again and produce vertical unstability, can cause that still vehicle climbs consequences such as folded.
Therefore how to take into account the design and the functional requirement of above two aspects, be the technical barrier of being badly in need of solution always.
Summary of the invention
Used for rail vehicle anti-creeper of the present invention; Be to solve the prior art defective and adopt the anti-creep structure that increases guide part; Thereby guiding car body bump occurs in the front of horizontal direction, forms from the front to impact to prevent that vehicle from producing to climb folded, serious consequence such as topple.
The objective of the invention is to, in case bump each other takes place vehicle, the structure of anti-creeper can energy-absorbing and is vertically pushed backward, moves along car body, realizes that promptly guided vehicle carries out frontal impact, prevents that vehicle from producing problem such as topple.
Another goal of the invention is, prevents that anti-creeper from producing vertical destabilization problems in loading process, prevents that when carrying out frontal impact vehicle from producing the problems such as folded of climbing.
For realizing the foregoing invention purpose, described used for rail vehicle anti-creeper mainly has:
Interconnective anti-creep portion and guide part, anti-creep portion front end is provided with anti-climbing tooth, the fastening car body end that is installed in of guide part;
Be filled with the buffering energy-absorbing parts in anti-creep portion and guide part inside;
Described anti-creep portion and guide part all have by steel plate welding box integral structure that form, an end opening;
The exterior contour size of anti-creep portion is less than guide part, and both carry out crosswise fixed at peg graft in opposite directions assembling and the shear pin through sidepiece.
Like above-mentioned basic scheme characteristic, the assembling of pegging graft in opposite directions of anti-creep portion and guide part, guide part itself just provides impact energy and the path of motion that is extruded, retreats of anti-creep portion when absorbing Vehicular impact.
Adopt shear pin to carry out crosswise fixed between anti-creep portion and the guide part and be connected, the two-part firm connection when pin can guarantee that vehicle normally moves.When bump took place vehicle, pin was hit power and is cut off, and anti-creep portion promptly slides backward along guide part, thus guiding train frontal impact.
At anti-creep portion and the inner buffering energy-absorbing parts (like the aluminium honeycomb) of filling of guide part; After above-mentioned pin is cut off, can guarantee anti-creep portion not promptly bullet from and cause two anti-creepers between the vehicle to break away from; But the blastic deformation that is accompanied by the end car body is little by little mobile backward, has guaranteed to bump against being meshing with each other between the vehicle anti-creeper.
For preventing that further anti-creeper from producing vertical destabilization problems in loading process, can take following innovative approach:
Vertical overlapping region at anti-creep portion and guide part is equipped with a pair of strengthening steel slab.
Anti-creep portion and guide part adopt the steel plate welding of certain thickness size to form; Install strengthening steel slab additional in both vertical overlapping regions again; Can guarantee that anti-creeper can not produce vertical unstability when car impact; Be that anti-creep portion only can be extruded and retreat along guide part, thereby avoid vehicle to produce the folded problem of climbing.
For prevent to peg graft in opposite directions stack-mounted anti-creep portion and guide part wave and deflection when vehicle normally moves, can be in the inside of anti-creep portion and guide part, the direction of pegging graft in opposite directions along both is provided with the pull bar that both are fastenedly connected.
Can cooperate above-mentioned shear pin through pull bar, and vertically being fastenedly connected at anti-creep portion and guide part.
More preferred improvement project with raising structural stability of guide part own and rigidity is to be provided with gusset on the surface of guide part.
As stated, used for rail vehicle anti-creeper of the present invention has the following advantages and beneficial effect:
1, adopt to increase the anti-creep structure of guide part, anti-creeper all energy-absorbing and guided vehicle carries out frontal impact, prevents the vehicle generation problem of toppling.
2, avoid anti-creeper in loading process, to produce vertical destabilization problems effectively, prevent that vehicle from producing the problems such as folded of climbing.
3, anti-creeper is simple in structure but have vertical and horizontal positioning function preferably, is easy to installation and removal.
