Abstract

The utility model relates to a coupler tail frame of a railway wagon coupler, and provides an abrasion-resistant coupler tail frame comprising a coupler tail frame, an abrasion plate and a connecting part, wherein, the abrasion plate adopts a plate like structure and is installed inside the inner surface of the lip end of the coupler tail frame, and the abrasion plate is fixedly connected with the lip end of the coupler tail frame through the connecting part. With the abrasion plate made of abrasion-resistant materials low in roughness, the abrasion-resistant coupler tail frame provided by the utility model isolates a rotating sleeve from direct contact and friction with the coupler tail frame, thereby extending the service life of the coupler tail frame, reducing the workload of inspection and repair, and curtailing the application cost.

Description

A kind of railway freight-car coupler hook tail frame

Technical field

The utility model relates to the traction shock absorber of rolling stock, and is especially relevant with a kind of hook tail frame of railway freight-car coupler.

Background technology

The hitch hook tail frame anterior lip end inwall of rolling stock is the moving cover contact of direct transfer at present, operating mode is unloaded in operation with the upset vehicle under, turning set and hook tail frame anterior lip end inwall produce extruding, abrasion, so that the wall thickness reduction of hook tail frame anterior lip end and influence fatigue life, need more maintenance workload and increase the utilization cost, even jeopardize safety of railway traffic.

The utility model content

Technical problem to be solved in the utility model provides a kind of wear-resisting type railway freight-car coupler hook tail frame, and its wearing plate that comprises can be avoided turning set and hook tail frame direct contact, improves the abrasion of hook tail frame anterior lip end inwall.Improve the service life of hook tail frame, reduce maintenance workload, lower the utilization cost.

For solving the problems of the technologies described above, the utility model proposes a kind of wear-resisting type railway freight-car coupler hook tail frame, comprise hook tail frame, it is characterized in that, also comprise wearing plate, attaching parts, described wearing plate is a platy structure, is installed in the hook tail frame lip end inside face, and wearing plate is captiveed joint by attaching parts with hook tail frame lip end.

As further improved plan, described hook tail frame lip end inwall is by machinework, casting or forge flutedly, and described wearing plate embeds in this groove.

Wear-resisting type hook tail frame of the present utility model adopts wear-resisting, the low material of roughness by wearing plate, has isolated the direct contact abrasion of turning set and hook tail frame, reduces maintenance workload the service life of having improved hook tail frame, lowers the utilization cost; Applicable to all swivel hook tail frames.

Description of drawings

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.

Fig. 1 is a hitch hook tail frame wear-resistant device scheme drawing of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to cutaway view;

Fig. 3 is the three-dimensional cutaway view of Fig. 1.

The specific embodiment

In conjunction with Fig. 1, Fig. 2, shown in Figure 3, the utility model wear-resisting type hook tail frame comprises wearing plate 1, hook tail frame 2 and attaching parts 3; Described wearing plate 1 is that numerical control cutting is shaped, and is embedded into the lip end inwall of hook tail frame 2, uses attaching parts 3 that wearing plate 1 is captiveed joint with hook tail frame 2 again.Hook tail frame 2 lip end inwalls can be by machinework, cast or forge a groove, embeds wearing plate 1 then, uses attaching parts 3 fastening wearing plate and hook tail frame again.

The key distinction of wear-resisting type hook tail frame and common hook tail frame is: because hook tail frame 2 lip end inside faces have added wearing plate 1, wearing plate 1 contacts with turning set, extruding and the abrasion having avoided existing hook tail frame 2 lip end inside faces directly to contact and produced with turning set, so the service life that can effectively improve hook tail frame, reduce maintenance workload, lower the utilization cost; Applicable to all swivel hook tail frames.

It should be noted last that, the above specific embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
