Abstract

The invention provides a railway wagon body support rod structure and a railway wagon body. The wagon body comprises end walls, side walls, a floor board and a bottom frame. The bottom frame is formed by a middle girder, a sleeping girder, a large beam and a small beam. The two end walls are located at two ends of the floor board and the lower portions of the two end walls are welded with the bottom frame. The two side walls are located at two sides of the floor board and the lower portions of the two side walls are welded with each beam of the bottom frame. The railway wagon body is characterized by further comprising the support rod structure. The support rod structure comprises an isosceles triangle formed by three support rods. Three vertices of the isosceles triangle are respectively fixed on the tow side walls and the floor board. Due to adoption of a triangular structure, rigidity of the overall wagon body is increased, stability is enhanced when a wagon runs, the triangular structure is good in force transference in the process of mechanical unloading, so that stress is dispersed and rate of damage is reduced.

Description

A kind of lorry body pole structure and lorry body

Technical field

What the present invention relates to is a kind of railway truck, particularly relates to the car body of railway truck.

Background technology

As shown in Figure 1, traditional lorry body is comprised of parts such as floor 5, headwall 2, side wall 6 and pole structure, for strengthening the coupling stiffness between both walls, prevents that side wall from rising outward, is provided with 3 groups of triatic stays 3 in car body.But along with railway truck to heavy duty, at a high speed and efficient trend development, the needs of the Fully-mechanized unloading in harbour, during the vehicle high-speed operation, external excitation increases the impact of car body, and intensity, rigidity and the stability etc. of body construction are required further to improve.3 groups of pole structure in body construction are not only being served as and are being connected the function that both walls strengthens car body rigidity, or the crawl position of automatic unloader, therefore strut is stressed larger, very easily damage, and traditional pole structure can not satisfy the demand of more and more functionalization.

Summary of the invention

The object of the present invention is to provide the lorry body pole structure that a kind of rigidity is large, can satisfy mechanical relief.The present invention also aims to provide a kind of lorry body.

The object of the present invention is achieved like this:

Lorry body pole structure of the present invention comprises by three struts forming an equicrural triangle, and three summits of described equicrural triangle are separately fixed on two framed side wallboards and floor of goods train carriage.

Lorry body pole structure of the present invention can also comprise:

1, be fixed with strut socket on two framed side wallboards of goods train carriage and floor, three summits of equicrural triangle are hinged on strut socket.

2, the end of three struts is connected rear composition equicrural triangle hinged with strut socket.

3, the hinged rear composition equicrural triangle of the end of three struts and strut socket.

4, the strut socket on the floor is positioned at the central sill place on floor, is fixed on central sill with stationary fixture.

Lorry body of the present invention comprises headwall, side wall, floor and underframe, described underframe is comprised of central sill, sleeper beam, cross bearer and needle beam, two ends, its underpart that two headwalls are positioned at the floor are connected with welding of underframe, and two side walls are positioned at each beam welding of both sides, its underpart and the underframe on floor; Also comprise pole structure, described pole structure comprises by three struts and forms an equicrural triangle, and three summits of described equicrural triangle are separately fixed on two framed side wallboards and floor.

Lorry body structure of the present invention can also comprise:

1, be fixed with strut socket on two framed side wallboards and floor, three summits of equicrural triangle are hinged on strut socket.

5, be provided with three groups of pole structure in a car body, three groups of pole structure equidistantly distribute.

Technical characteristics of the present invention is: consist of lorry body by the end wall panel at floor, the framed side wallboard that is positioned at the both sides, floor and two ends etc., using strut in same plane, two framed side wallboards to be connected with the floor connects, form an equicrural triangle, be provided with altogether three groups in car body.Be fixed with strut socket on each plate, adopt articulated structure to be connected between strut and strut socket.

Pole structure is divided into two kinds of situations: the one, and be captive joint between three rod components of strut, form a fixed tripod, and then hinged with strut socket; Another kind of situation is independent, and each rod component is hinged with strut socket respectively in one group, and three rod components are relatively rotatable.

Strut socket on framed side wallboard is that rivet is connected with side wall, and its position is just on the column of side wall, and is identical with the position of traditional car body.Another key point of the present invention is the strut socket on the floor, and it is positioned on the central sill on floor, with stationary fixture, strut socket is fixed on central sill.So both do not reduce the intensity of emphasis stressed member central sill own, increased again the integral rigidity of car body.

Beneficial effect of the present invention is: with respect to the pole structure of traditional railway truck, the triangular structure that the present invention adopts has increased the rigidity of car body integral body, and stability is strengthened in the vehicle operating process; Process intermediate cam shape structure in the mechanization unloading can better be transmitted power, makes stress dispersion, reduces the probability of damage.

The specific embodiment

For example the present invention is done more detailed description below in conjunction with accompanying drawing:

In conjunction with Fig. 2 and shown in Figure 3, lorry body of the present invention is by headwall 2, side wall 6, and the compositions such as floor 7, strut bar 4 and underframe, wherein underframe is comprised of central sill 1, sleeper beam, cross bearer and needle beam etc. again.Whole car body has two headwalls 2, is positioned at the two ends on floor 7, and its underpart is connected with welding of underframe; Whole car body has two side walls 6, is positioned at the both sides on floor 7, each beam welding of its underpart and underframe;

Whole car body has three groups of strut bars, connects two side walls and underframe, adopts articulated structure to be connected between strut and strut socket.With regard to one group of strut, formed a pole structure and three strut sockets by two parts.As shown in Figure 4, be captive joint between three rod components of pole structure, form the tripod that can not relatively move.Strut socket is divided into again two classes, and the strut socket 3 that is connected with side wall is riveted joint, and the strut socket 5 that is connected with the floor central sill is connected for fixture, and the fixture schematic diagram as shown in Figure 3.
