Description

Anticreeper for rail vehicle

Technical Field

The utility model relates to a be applied to anticreeper that rail vehicle used when taking place the striking belongs to the machine-building field.

Background

At present, the speed per hour of domestic rail vehicles reaches 380 km/h, and in order to reduce the huge damage to the vehicle body structure caused by mutual impact of the rail vehicles, safety protection devices such as anti-creepers and the like are usually arranged at the end parts of the vehicle body and between the vehicles.

The purpose of designing, using the anticreeper is, can be when taking place mutual striking anti-creep tooth intermeshing, carry out the frontal impact between the automobile body and make automobile body tip take place to warp in order to absorb huge impact energy, and then prevent that the vehicle from producing to climb serious consequences such as folding, toppling, avoid causing losses such as casualties.

The anti-creeper that current domestic rail vehicle used adopts the structure and the connected mode of steel sheet tailor-welding universally, if the structural rigidity of this type of anti-creeper was too high, then can only transmit the chassis with the impact force when the vehicle strikes each other and reduce the lifting surface to unable all absorption impact energy, the vehicle is easily turned on one's side or topples. If the structural rigidity of the anti-creeper is too low, the anti-creeper is easy to generate vertical instability under the action of vertical load offset, and the vehicle can still climb and fold and other consequences.

Therefore, how to consider the design and function requirements of the above two aspects is a technical problem which is always urgently needed to be solved.

SUMMERY OF THE UTILITY MODEL

Anticreeper for rail vehicle, lie in solving prior art defect and adopt the anti-creep structure that increases the guide part to guide automobile body striking to take place in the front of horizontal direction, from positive formation impact in order to prevent that the vehicle from producing to climb serious consequences such as folding, toppling.

The utility model discloses a design aim at, in case the vehicle takes place to strike each other, the structure of anticreeper can the energy-absorbing and along the vertical backward extrusion of automobile body, remove, realize promptly that the guide vehicle carries out the frontal impact, prevent that the vehicle from producing the scheduling problem that topples.

Another design objective is, prevent that the anticreeper from producing vertical unstability problem in the atress process, prevent that the vehicle from producing when carrying out the frontal impact and climb and fold the scheduling problem.

In order to achieve the above design purpose, the rail vehicle anticreeper mainly comprises:

the anti-climbing device comprises an anti-climbing part and a guide part which are connected with each other, wherein anti-climbing teeth are arranged at the front end of the anti-climbing part, and the guide part is tightly installed at the end part of a vehicle body;

the anti-creeping part and the guide part are internally filled with buffering energy-absorbing parts;

the anti-creeping part and the guide part are both of box-shaped integral structures which are formed by welding steel plates and have one open end;

the external contour dimension of the anti-creeping part is smaller than that of the guide part, and the anti-creeping part and the guide part are oppositely spliced and assembled and transversely fixed through the shearing pins on the side parts.

As described above, according to the features of the basic solution, the anti-creep portion and the guide portion are inserted and assembled in opposite directions, and the guide portion itself provides a movement locus in which the anti-creep portion is pressed and retreated while absorbing impact energy at the time of vehicle collision.

The anti-creeping part and the guide part are transversely and fixedly connected by the shearing pin, and the pin can ensure the firm connection of the two parts when the vehicle normally runs. When the vehicle is impacted, the pin is sheared by the impact force, and the anti-creeping part slides backwards along the guide part, so that the front impact of the train is guided.

The buffering and energy-absorbing part (such as aluminum honeycomb) filled in the anti-creeping part and the guide part can ensure that the anti-creeping part cannot be rapidly bounced off to cause the separation of the anti-creeping devices between two vehicles after the pin is sheared, and gradually moves backwards along with the impact deformation of the vehicle body at the end part, thereby ensuring the mutual engagement between the anti-creeping devices of the colliding vehicles.

In order to further prevent the vertical instability problem of the anti-creeper in the stress process, the following improvement measures can be taken:

and a pair of reinforcing steel plates are arranged in the vertical overlapping area of the anti-creeping part and the guiding part.

The anti-creep portion and the guide portion are formed by welding steel plates with certain thickness and size in a splicing mode, the reinforcing steel plates are additionally arranged in the vertical overlapping area of the anti-creep portion and the guide portion, the anti-creep device can be guaranteed not to generate vertical instability when the vehicle impacts, namely, the anti-creep portion can only be extruded and retreated along the guide portion, and therefore the problem that the vehicle is prevented from creeping and folding is solved.

In order to prevent the anti-climbing part and the guide part which are oppositely spliced and assembled from swinging and deflecting during the normal running of the vehicle, pull rods for fastening and connecting the anti-climbing part and the guide part can be arranged in the anti-climbing part and the guide part along the opposite splicing direction of the anti-climbing part and the guide part.

The pull rod can be matched with the shearing pin to be firmly connected with the longitudinal direction of the anti-creeping part and the guide part.

More preferably, the improvement scheme for improving the structural stability and rigidity of the guide part is that a rib plate is arranged on the surface of the guide part.

As described above, the utility model discloses anticreeper for rail vehicle has following advantage and beneficial effect:

1. by adopting the anti-climbing structure with the guide part, the anti-climbing device can absorb energy completely and guide the vehicle to carry out frontal impact, so that the vehicle is prevented from overturning.

2. The problem that the anti-creeper generates vertical instability in the stress process is effectively avoided, and the problems that vehicles generate climbing and folding and the like are prevented.

3. The anti-creeper has simple structure, better longitudinal and transverse positioning functions and easy installation and disassembly.
