Description

Technical Field

[0001] The invention belongs to the technical field of railway equipment design, in particular to the technical field of railway freight vehicle component design, and specifically relates to a wide-mouth welded impact seat for railway freight vehicles. Background Art

[0002] In railway transportation, the impact seat is an important component of railway freight cars and plays an important role. It is fixed to the vehicle traction beam together with the front and rear follower plate seats, thereby realizing the connection between vehicles and the transmission of longitudinal force. At present, the existing railway freight car impact seats are mainly divided into casting type and assembly welding type. The mold production cycle of the casting impact seat is relatively long, which is suitable for the situation of mature structure and large-scale production; the assembly welding impact seat only needs to weld and assemble the steel plate by itself, which is suitable for new products, short R&D cycle and low production.

[0003] The cast impact seat used in existing railway freight vehicles cannot meet the use requirements of the extended E / F type coupler. Due to the small width of the hook mouth, the extended E / F type coupler is easy to interfere with it during use, thus causing train operation accidents. If the mold design for the extended E / F type coupler is too long and the cost is high, the assembly welded impact seat can choose different hook mouth widths according to different lengths of couplers, which is more flexible and economical than the cast impact seat. Summary of the invention

[0004] The object of the present invention is to solve the above-mentioned problem and to provide a wide-mouth welded railway freight car impact seat that meets the design of an extended E / F type coupler.

[0005] The present invention is achieved through the following technical solutions:

[0006] The wide-mouth welded impact seat for railway freight cars is characterized in that: a "mouth"-shaped structure is formed by welding a horizontally arranged upper cover plate, vertical plates arranged on both sides respectively, and a horizontally arranged lower support plate;

[0007] The rear end of the upper cover plate and the rear end of the lower support plate are both extended into the inner side of the coupler hole of the end beam of the railway freight car body, and are welded and fixed to the end beam of the car body; the lower support plate is located on the upper plane of the "mouth"-shaped structure and is fixed with a replaceable wear plate and an adjustment pad by bolts;

[0008] The upper plane of the upper cover plate is welded and fixed with three groups of triangular reinforcing rib plates 1 at intervals, and each reinforcing rib plate 1 is also welded and fixed to the vehicle body end beam and the vehicle floor; the lower plane of the lower support plate is welded and fixed with three groups of triangular reinforcing rib plates 2 at intervals, and each reinforcing rib plate 2 is also welded and fixed to the vehicle body end beam.

[0009] The vertical plates on both sides are arranged in parallel to form a square opening or outwardly to form a trumpet-shaped opening.

[0010] The front end of the upper cover plate is in an arc shape, and the rear end has the same width as the coupler hole of the railway freight car body end beam and extends into the inner side of the coupler hole of the railway freight car body end beam for welding and fixing.

[0011] An integral reinforcing seat is welded and fixed to the upper plane of the arc-shaped structure at the front end of the upper cover plate.

[0012] The reinforcement seat is composed of a bent plate welded and fixed to both sides of the upper cover plate and an inclined plate arranged obliquely between the two bent plates to form an inverted reinforcement structure.

[0013] The rear end portion of the lower supporting plate has the same width as the coupler hole of the railway freight car body end beam and extends into the inner side of the coupler hole of the railway freight car body end beam and is welded and fixed.

[0014] The benefits of the present invention are as follows: the impact seat of the present invention fully meets the use requirements of extended car hooks of different specifications through different assembly welding forms of steel plates. The assembly welded impact seat is lighter than the cast impact seat of the same size and can meet the demand for lightweight. The reinforcement seat at the upper cover plate of the impact seat of the present invention is in an inverted shape, which not only plays a reinforcing role but also effectively isolates rainwater, etc.; and the ribs arranged at the upper cover plate and the lower cover plate increase the strength of the impact seat.
