Abstract

The invention discloses a climbing prevention device which comprises a floor board fixedly connected with a vehicle body underframe; an underframe edge beam is fixedly connected to each of the left side and the right side of the floor board; the front end of the floor board is fixedly connected with a climbing prevention beam arranged at the end part of a vehicle; the two ends of the climbing prevention beam are connected to the corresponding underframe edge beams respectively; at least three compression beams are arranged between the vehicle body underframe and the climbing prevention beam; transversally arranged teeth are arranged on the outer side of the climbing prevention beam; and when two vehicles collide with each other, the teeth of the climbing prevention beam are meshed with the teeth of the climbing prevention beam of the other vehicle. The climbing prevention device solves the problem that the mounting space of the climbing prevention device at the front end of the vehicle body underframe of the lead vehicle is limited, plays a role of preventing climbing when two vehicles collide, and prevents the vehicle main body structure from being damaged by controlled deformation of a selected area; and the collision energy (kinetic energy) is converted into controlled deformation in the manner of ensuring that passengers and stewards have enough living space.

Description

A kind of anti-creeper

Technical field

The present invention relates to belong to guideway vehicle manufacturing technology field, be specially a kind of anti-creeper.

Background technology

At present, the freestanding anti-creeper of the many employings of domestic guideway vehicle anti-creeper, be installed on the vehicle body bottom frame end by bolt, as shown in Figure 1, the advantage of this kind scheme is replaceable after the collision anti-creeper damages, and shortcoming is that anti-creeper is installed and need to be taken up room, some guideway vehicle installing space is limited, can't install, and freestanding anti-creeper is because outstanding car body front end surface, overall aesthetics and safety are not fine.

Summary of the invention

Be subject to the installing space restriction for some guideway vehicle front end, the deficiency that free-standing anti-creeper can't be installed, the present invention aims to provide a kind of anti-creeper, this anti-creeper takes up room little, can be installed in easily the guideway vehicle front end, when two trains occur to bump against, play the effect of anti-creep.

To achieve these goals, the technical solution adopted in the present invention is:

A kind of anti-creeper, its constructional feature is, comprise the floor of captiveing joint with vehicle body bottom frame, this floor each side be fixedly connected with a foundation frame side bar, the front end on described floor is captiveed joint with the anti-creep beam that is arranged on vehicle end, and the two ends of this anti-creep beam are connected on the corresponding edge beam of underframe; Be provided with at least three conquassation beams between described vehicle body bottom frame and the anti-creep beam, the outside of described anti-creep beam has the tooth of horizontally set, and the tooth of this anti-creep beam is meshed with tooth on the anti-creep beam of another vehicle anti-creeper when two vehicles collides.

Below be the technical scheme of further improvement of the present invention:

For fixing conquassation beam preferably, make the conquassation beam bring into play more fully energy-absorbing function, described conquassation beam is captiveed joint with the floor.

Described conquassation beam of the present invention and vehicle operating direction are the α angle, wherein 0≤α≤45 °.

As a kind of concrete version, described anti-creep beam integral body is curved, and the back of a bow of arc is towards the end of vehicle.

In order to guarantee that anti-creeper and another anti-creeper mesh better, the tooth of described anti-creep beam is stepped tooth.

Have a plurality of breach or hole on the described conquassation beam, induce the anti-creeper collision deformation to be undertaken by controlled manner.

By said structure, a kind of anti-creeper comprises two edge beam of underframes, an anti-creep beam, three conquassation beams and a floor.Two edge beam of underframes are positioned at anti-creeper the right and left, with Undercarriage structure, and the effect of playing support, carrying and transmitting longitudinal force; The anti-creep beam is positioned at the end of vehicle, is band tooth Aluminum Hollow section bar, by bending forming, about be connected with edge beam of underframe, the rear end is connected with the conquassation beam with the floor; Conquassation beam front end is connected with the anti-creep beam, and the rear end is connected with Undercarriage structure, and simultaneously conquassation beam is connected on the floor by the section weldering; Floor the right and left is connected with edge beam of underframe, and front end is connected with the anti-creep beam, and the rear end is connected with Undercarriage structure.Wherein edge beam of underframe, anti-creep beam, conquassation beam are the hollow extruded aluminium section, and the floor is sheet material, and welding is all adopted in the connection between them.

Described anti-creeper is applicable to guideway vehicle, and anti-creeper and vehicle body bottom frame are welded as a whole, and is not connected with vehicle body bottom frame by bolt separately, has saved installing space.

The shape of anti-creeper can become different arcs with the clod wash of anti-creep beam according to the moulding of vehicle front, to satisfy the moulded needs of vehicle, improves the aesthetics of vehicle.

According to the crash energy absorption requirement of different automobile types, design conquassation beam, the section form of adjustment conquassation beam, spacing, angle of inclination etc. absorb the collision energy that designs predetermined quantity.

Compared with prior art, the invention has the beneficial effects as follows:

1, anti-creeper when two trains occur to bump against, plays the effect of anti-creep by being welded to connect in the car body end.

2, anti-creeper absorbs collision energy by controllable deforming, guarantees that passenger and Train Conductors have enough living spaces.

3, anti-creeper can need according to the different moulding of vehicle, and cold roll forming becomes different arcs.

4, anti-creeper is as a whole, has beautified the outward appearance of car body.

The present invention is further elaborated below in conjunction with drawings and Examples.
