Abstract
The utility model discloses a wagon upper center plate assembly and belongs to fitting equipment of railway wagons. The wagon upper center plate assembly comprises a draft sill and an upper center plate. A center protrusion piece is arranged on the lower surface of the upper center plate. A groove is arranged in the upper surface of the draft sill. The grove corresponds to the center protrusion piece. The center protrusion piece is embedded into the groove. The periphery of the lower surface of the upper center plate is fixedly connected with the upper surface of the draft sill. The wagon upper center plate assembly is simple is structure and convenient to assemble, examine and maintain. Cost for examining and maintaining wagons is reduced, practical performance of wagons is improved, and practical efficiency of wagons is improved.
Description
Technical field
The utility model belongs to the goods train vehicle fittings equipment, relates to a kind of lorry body center plate assembly.
Background technology
At present, the body center plate assembly connecting mode that railway truck is commonly used mainly contains riveted type, integral type and three kinds of structures such as embedded.Riveted type body center plate unit construction is riveted on body center plate on the draw beam by rivet, and its principal feature is simple in structure, and maintenance is convenient, but has the easy cut possibility of rivet; Integral type body center plate unit construction is cast as one body center plate and rear draft lug, and welds with draw beam, and this structure has solved the easy cut possibility of riveted type rivet, but has brought tired very greatly warm for maintenance in the future.Embedded body center plate unit construction is boss and the groove structure that body center plate and center filler pass through interference fit, and body center plate is welded and fixed on the draw beam, this structural advantages and integral type body center plate are similar, but need when replacing with cartridge by special tooling body center plate is taken out, and maintainability is poor.
The utility model content
Technical problem to be solved in the utility model provides a kind of lorry body center plate assembly simple in structure and easy to assembly.
For solving the problems of the technologies described above, the utility model provides a kind of lorry body center plate assembly, comprise a draw beam and a body center plate, the lower surface of described body center plate has a center projection, the groove that the upper surface setting of described draw beam is corresponding with described center projection, described center projection embeds in the described groove, captives joint with described draw beam upper surface around the described body center plate lower surface.
Further, described center projection has pattern draft.
Further, described pattern draft is the 4-6 degree.
Further, described center projection is square.
Further, described groove is counter bore structure.
Further, four arms of angle of described body center plate lower surface have respectively an edge projection.
Further, described edge projection is planar structure.
Further, be ramp structure between the described edge projection.
A kind of lorry body center plate assembly that the utility model provides, simple in structure, assembling and maintenance are convenient, can reduce the car inspection and maintenance cost, improvement vehicle Practical Performance, the practical efficient of raising vehicle.
Description of drawings
A kind of body center plate schematic perspective view that Fig. 1 provides for the utility model embodiment;
A kind of lorry body center plate unit construction schematic diagram that Fig. 2 provides for the utility model embodiment;
1, draw beam, 2, body center plate, 3, the center projection, 4, the edge projection, 5, the inclined-plane.
The specific embodiment
Referring to Fig. 1, a kind of body center plate schematic perspective view that the utility model embodiment provides, the utility model comprises a draw beam 1 and a body center plate 2, the lower surface of body center plate 2 has a center projection 3, at the upper surface of draw beam 1 groove corresponding with center projection 3 arranged, center projection 3 embeds in the groove, is the free-running fit state, welds with draw beam 1 upper surface around body center plate 2 lower surfaces.(referring to Fig. 2).
Wherein, center projection 3 has pattern draft, and pattern draft is the 4-6 degree, and center projection 3 is square, and groove is counter bore structure, and center projection 3 and groove structure are succinct, is easy to guarantee the vertical and located lateral of body center plate 2.
Wherein, four arms of angle of body center plate 2 lower surfaces are cast with respectively an edge projection 4, are easy to guarantee the vertical gap between body center plate and the draw beam lower cover, are ramp structure between four edge projections 4, are easy to guarantee welding quality.This edge projection 4 is in the value that the planeness that guarantees four faces behind the casting by mach mode is requiring, and the existence of this edge projection 4 has been easy to guarantee the welding fabrication quality on the welding inclined-plane 5 between body center plate and the draw beam lower cover.
During assembling, center projection 3 is embedded in the groove, adopt special tooling to guarantee during assembling, after four edge projections 4 and the lower cover of draw beam 1 of body center plate 2 were located, whole assembling process was namely finished on the inclined-plane 5 between welding body center plate 2 and the draw beam 1.
The utility model is on the basis that does not change body center plate module body structure, free-running fit between the groove of body center plate projection and draw beam has guaranteed the vertical and located lateral of body center plate, the confined planes of appropriate location can guarantee that the vertical gap of body center plate and draw beam lower cover is even, is easy to the control of welding quality.
The utility model is simple and reasonable, the central boss of employing and groove structure can guarantee body center plate vertically and located lateral, the edge projection cube structure of employing can guarantee body center plate between vertical gap even, be easy to the control of welding quality.Simultaneously this structure assembling and maintenance is convenient, can reduce the car inspection and maintenance cost, improvement vehicle Practical Performance, the practical efficient of raising vehicle.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example the utility model is had been described in detail, 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.
