Abstract

The utility model provides a fixed coupler for a railway car, which comprises a coupler body (3), a lower detent (2), a lower detent shaft (7), a coupler knuckle (5), a coupler knuckle pin (4) and a coupler lock (1). The utility model is characterized in that an upper frame (6) is fixed on the head of the coupler body relatively to the upper part of the coupler knuckle. The upper frame (6) comprises two installation stands (6.1) and a stopper (6.2) supported by the two stands. The stopper is arranged toward the coupler knuckle. The two installation stands (6.1) are welded on the head of the coupler body. The utility model has the advantages that the upper frame can prevent the coupler knuckle from jumping out, the situation that one coupler gets separated from another coupler is prevented, the upward movement of the broken coupler knuckle is prevented and the situation that the broken coupler hits the end of the car is avoided.

Description

Fixedly hitch of rolling stock

Technical field

The utility model relates to fixedly hitch of a kind of rolling stock, is used for the tank car field, also relates to the railway truck that shipment has pollution, dangerous freight simultaneously.

Background technology

The hitch of railway truck dress usefulness mainly contains two types, E type hitch and F type hitch at present.In vehicle operating, run into when the hitch disengagement is takeoff and the hook tongue ruptures, the part that hitch is thrown off and the hook tongue of fracture be the end of vehicle impact very likely, and along with China railways heavy duty fast freight policy execution, the power that hitch bears is also strengthening, and its probability that fracture takes place is also increasing.

Tank car is as through being commonly used to transport the rolling stock that contains characteristic goods such as pollution, danger, more should avoid because the damage that the hitch fracture causes its tank body, thereby avoid the leakage of shipping goods and the accident that causes and to the pollution of environment.

Summary of the invention

The purpose of this utility model just provides a kind of fixedly hitch of rolling stock of avoiding the hitch accident vehicle end portion structure to be caused damage.

The technical solution of the utility model: rolling stock of the present utility model comprises coupler body, lock pin, lock pin rotating shaft, hook tongue, knuckle pivot pin, hook lock down down with fixing hitch, on coupler body head m face with respect to connect extension hook tongue top fix divider structure on.

The described divider structure that goes up comprises that two installations are kept a foothold and by the retaining head of keeping a foothold and supporting, the retaining head arranges that facing to the hook tongue two installations are kept a foothold and are welded on the coupler body head m face.

Advantage of the present utility model is: simple in structure, easily manufactured, use reliably, and good to the inheritance and the interchangeability of original hitch.The described divider structure that goes up can stop that the hook tongue jumps out, thereby stops the disengagement between the hitch and stop fracture hook tongue upward movement, avoids its vehicle impact end, can effectively satisfy the needs that rolling stock is transported safely.

The specific embodiment

In conjunction with the accompanying drawings the utility model is described in further detail:

As Fig. 1, Fig. 2, Fig. 3, Fig. 4: the utility model comprises coupler body 3, lock pin 2, lock pin rotating shaft 7, hook tongue 5, knuckle pivot pin 4, hook lock 1 down down, on the head m of coupler body 3 face with respect to connect extension the position of hook tongue fix divider structure 6 on.

Fig. 5, Fig. 6 keep a foothold 6.1 and the retaining that supports by keeping a foothold 6.2 for divider structure 6 on the last divider comprises two installations, and the retaining head is arranged facing to the hook tongue.Two installations are kept a foothold and 6.1 are welded on the coupler body head m face.

Coupler body is fastened on the vehicle central sill with hook tail frame by draft key, realizes the purpose of two coupling of vehicles.

After can casting separately, last divider 6 is welded on the gib head m face of coupler body by the n face of keeping a foothold on 6.1 again, or be cast as one with coupler body 3, divider 6 can stop that hook tongue 5 jumps out in the realization, thus the purpose that stops the disengagement between the hitch and stop fracture hook tongue upward movement.

Principle of work of the present utility model is such: keep the accessory of original hitch constant, only on the gib head top of coupler hook body with respect to the position on the connect car coupler knuckle top that hangs, weld or cast one and go up the divider structure, this divider can stop that the hook tongue jumps out, thereby disengagement between the prevention hitch and prevention fracture hook tongue upward movement, avoid its vehicle impact end, can effectively satisfy the needs that rolling stock is transported safely.

Claims

1. a rolling stock is with fixing hitch, comprise coupler body (3), down lock pin (2), lock pin rotating shaft (7), hook tongue (5), knuckle pivot pin (4), hook lock (1) down, it is characterized in that: on coupler body head m face with respect to connect extension hook tongue top fix divider structure (6) on.

2. fixedly hitch of rolling stock according to claim 1, it is characterized in that: go up that divider structure (6) comprises that two installations are kept a foothold (6.1) and by the retaining head (6.2) of keeping a foothold and supporting, retaining head arranges facing to the hook tongue, two installations keep a foothold (6.1) be welded on the coupler body head m face.
