Abstract
The utility model discloses a climbing guard part for railway vehicles. A climbing guard parting structure additionally provided with a guide part is used so as to guide a vehicle body to collide in front surface of horizontal direction, thus the impact is formed at the front surface so as to prevent the vehicle from being overlapped by climbing and overturned. The climbing guard comprises a climbing guard part and a guide part connected with each other. Climbing guard teeth are arranged on the front end of the climbing guard part. The guide part is fixedly installed at the end of the vehicle body. Buffer energy absorption parts are filled in the climbing guard part and the guide part. Both the climbing guard part and the guide part comprise a box type integral structure made of steel plate by welding, one end of box type integral structure is open. The size of the outer outline of the climbing guard part is less than that of the guide part, and the two are assembled in opposite direction by splicing and transversely fixed through a cutting pin at side. The climbing guard part and the guide part are oppositely spliced, the guide part supplies the motion trail when the climbing guard part is extruded and retreated by absorbing the impact energy of the vehicle collision.
Description
Technical field
The utility model relates to a kind of anti-creeper of using when bump takes place guideway vehicle of being applied to, and belongs 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 mutually 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 mutually, 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 mutually, impulsive force only be passed to underframe and reduce area of thrust surface, thereby can't all absorb impact energy, vehicle is easily turned on one's side or is toppled.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.
The utility model content
Used for rail vehicle anti-creeper described in the utility model, 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.
Design goal of the present utility model is, in case bump mutually takes place vehicle, the structure of anti-creeper can energy-absorbing and 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 design goal 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 above-mentioned design goal, 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 opposite to each other assembling and the shear pin by sidepiece.
As above-mentioned basic scheme feature, the assembling of pegging graft opposite to each other of anti-creep portion and guide part, guide part itself with regard to provide anti-creep portion when absorbing Vehicular impact impact energy and the path of motion that is extruded, retreats.
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 (as 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 by 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 mentioned above, the utility model used for rail vehicle anti-creeper 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.
