Abstract

The utility model relates to a railway wagon pedal and belongs to the technical field of railway wagon and machinery. The railway wagon pedal comprises a pedal body and a pedal seat, wherein the pedal body is provided with a footboard and a support board, the support board is connected with a protection board and a rib board is arranged between the footboard and the pedal body. The railway wagon pedal is characterized in that one end of the pedal seat is bent to form a connection frame, the upper end of the pedal seat is installed on a first installation face of a wagon body, the pedal body is installed on the connection frame, and a buffer gap is formed by one face of the connection frame and a second installation face. The railway wagon pedal has the advantages that a micro buffer gap is reserved between the pedal seat and the wagon body, when the pedal body is stressed by internal and external force along the transverse direction of the wagon body, the pedal body can drive the pedal seat to bend towards the wagon inward direction till to contact with the second installation face, and therefore the purpose of buffering or reducing deformation of the pedal can be achieved by a helping role of the buffer gap.

Description

A kind of railway wagon pedal

Technical field

The utility model relates to a kind of railway truck pedal, belongs to railway truck and field of mechanical technique.

Background technology

At present, railway truck comprises pedal body 4 and pedal seat 1 with pedal as shown in Figure 1, and pedal 5 and supporting plate 8 are installed on the pedal body 4, and supporting plate 8 connects backplate 7, is provided with gusset 6 between pedal 5 and pedal body 4, and pedal body is installed on the car body.There is following shortcoming in the pedal of this structure: supporting plate adopts steel plate to make, and without antiskid function, causes potential safety hazard; Pedal body directly is connected with car body, and under the mechanical external force effects such as forklift, pedal very easily produces flexural deformation to the car body internal direction, according to statistics, approximately has pedal about 30% that in various degree distortion is arranged during maintenance.

Summary of the invention

Problem to be solved in the utility model provides a kind of safe and on-deformable railway truck pedal for above deficiency exactly.Its technical scheme is as follows:

It comprises pedal body and pedal seat, and pedal and supporting plate are installed on the pedal body, and supporting plate connects backplate, is provided with gusset between pedal and pedal body.Its gordian technique is that pedal seat one end is bent to form connection box, and the pedal seat upper end is installed on the first attachment face of car body, and pedal body is installed on the connection box, and the one side of connection box forms dash clearance with the second attachment face of car body.

Compared with prior art the beneficial effects of the utility model are:

1, leaves small dash clearance between pedal seat and the car body, when pedal body is subjected to along the inside External Force Acting of cross-car direction, will drive pedal seat together in the car direction crooked until contact with the second attachment face, thereby the booster action by dash clearance plays buffering or reduces the distortion of pedal.

2, punching press hole on supporting plate has improved the antiskid capability of product and the comfort that operating personal is ridden, and has promoted the safety of product;

3, adopt pulling rivet to be connected between pedal seat and the pedal body, rational in infrastructure, increased the reliability of product.

The specific embodiment

Referring to Fig. 2-Fig. 7, the utility model comprises pedal body 4 and pedal seat 1, and pedal 5 and supporting plate 8 are installed on the pedal body 4, and supporting plate 8 connects backplate 7, is provided with gusset 6 between pedal 5 and pedal body 4.Its gordian technique is that pedal seat 1 one ends are bent to form connection box 11, pedal seat 1 upper end is installed on the first attachment face 10 of car body by pulling rivet 3, pedal body 4 is installed on the connection box 11 by connecting panel 2 and pulling rivet 3, the one side of connection box 11 forms dash clearance 9, punching press hole 12 on supporting plate 8 with the second attachment face of car body.Described pedal seat 1 adopts the band steel bending to make.

During the operating personal climbing, need first pin to step on supporting plate 8, continue upwards climbing such as need, can realize by pushes pedals 5.Punching press hole 12 on supporting plate 8 satisfies the hommization requirement of product, and comfort level is high; Adopt pulling rivets 3 to be connected by connecting panel 2 between pedal seat 1 and the pedal body 4, play the slip-off preventing effect, thereby the safety of assurance operating personal has increased the reliability of product; Leave small dash clearance 9 between pedal seat 1 and the second attachment face, when pedal body 4 is subjected to along the inside External Force Acting of cross-car direction, will drive pedal seat 1 together in the car direction crooked until contact with the second attachment face, thereby the booster action by dash clearance 9 plays buffering or reduces the distortion of pedal.
