Description

A detachable closed frame type integral impact seat

technical field

The invention belongs to the technical field of railway equipment design and manufacture, in particular to the technical field of railway vehicle coupling device design, and particularly relates to a detachable closed frame-type integral impact seat.

Background technique

The impact seat is one of the key components of railway vehicles. When the vehicle is running, collision and friction will occur between the coupler buffer device and the impact seat. There is a wear plate on the seat. The setting method of the wear plate is as follows: a wear plate connected by welding is arranged at the contact part of the impact seat body and the buffer; an adjustment pad for adjusting the height of the coupler is arranged on the support surface of the impact seat coupler, and is connected with the impact seat. The seat is welded, and the wear plate is arranged above the adjusting backing plate and is welded with the adjusting backing plate. The structure of this setting method is relatively complicated, and when repairing the wear plate, it is necessary to cut the old wear plate first, and then re-weld the new wear plate, which is not only inconvenient to operate, time-consuming and labor-intensive, but also damages the impact seat body if the operation is improper.

The problem to be solved by the present invention is to provide an impact seat which can satisfy the quick disassembly of the wear structure of the impact seat, the vertical support of the coupler, the transmission of the longitudinal force and the adjustment of the height of the coupler.

The present invention is achieved through the following technical solutions:

The detachable closed frame-type integral impact seat includes a frame-type integral impact seat, and a wear plate is arranged inside the impact seat, and is characterized in that: the wear plate includes a support surface wear plate and an impact seat that are detachably arranged on the bottom surface of the inner side of the impact seat. Rear wear plates on inner side and rear side;

The support surface wear plate is a flat structure wear plate made of nylon with a front locking buckle and a rear locking buckle; the supporting surface wear plate is fixed on the bottom surface below the entrance of the impact seat through the front locking buckle and the rear locking buckle;

The rear wear plate is provided with two pieces, which are respectively fixed on the inner side surface and the rear end surface of the impact seat by connecting bolts.

Further, the front locking buckles of the support surface wear plate are fully covered along the front end surface of the support surface wear plate, and the rear locking buckles are arranged in two groups along both sides of the rear end surface of the support surface wear plate; the front locking buckle and the rear locking buckle are both L The L-shaped inverted structure is embedded and fastened with the locking piece provided below the entrance of the impact seat.

Further, the connecting bolts of the rear wear plate are arranged on the rear end surface of the impact seat.

The impact seat of the present invention is an integral casting structure, and the coupler supporting surface is an integral closed frame structure.

The invention adopts a detachable closed frame type integral impact seat, and a support surface wear plate and a rear wear plate of the impact seat are arranged on the inner side of the impact seat. The impact seat is integrally cast, and the rear wear plate at the contact part between the impact seat body and the buffer is provided with bolt holes and is connected with the seat body by bolts; the support surface wear plate set on the support surface of the impact seat coupler adopts oil-containing nylon wear plate The structure can be disassembled, and different sizes of wear plates can be selected according to the actual situation of the hook height.

The beneficial effect of the present invention is that, compared with the existing closed frame type integral impact seat, the impact seat of the present invention has a more reasonable structure, not only can realize the adjustment of the height of the coupler, but also the wear plate is arranged in a detachable structure, which is more convenient for disassembly and replacement. , which is conducive to the maintenance and replacement of the wear plate, and further avoids damage to the impact seat body. The invention can satisfy the quick disassembly of the impact seat, the vertical support of the coupler and the transmission of the longitudinal force, and can realize the adjustment of the height of the coupler; The wear plate is provided with bolt holes and is connected with the impact seat body by bolts, which has the advantages of simple structure, convenient replacement of the wear plate, avoids damage to the impact seat body, and can reduce vehicle maintenance time and vehicle maintenance costs.
