Abstract
The utility model relates to a car body and hook connecting device, which belongs to the field of a rail wagon. The car body and hook connecting device comprises a hook supporting beam, a hook and a middle beam; the hook supporting beam comprises a supporting beam seat, a connecting plate and a supporting vertical plate, the inner side of the supporting beam seat is provided with an installation groove which is matched with the shape of the front end of the middle beam, the lower end of the supporting beam seat is fixedly provided with the connecting plate, the connecting plate is provided with a connecting bolt hole for fixing the middle beam, the lower surface of the connecting plate is vertically and fixedly provided with one supporting vertical plate, and two reinforcing ribbed plates are arranged between the supporting vertical plate and the connecting plate; the hook supporting beam is fixed on the bottom of the middle beam through a connecting plate screw, so that the supporting beam seat of the hook supporting beam is used as a downward supporting body; the supporting beam seat of the hook supporting beam is embedded into the front end of the middle beam through the installation groove so as to be transversely positioned. By adopting the car body and hook connecting device, the reliability in connection of a car body and the hook can be improved, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of car body and hitch connecting device, belongs to railway truck field.
Background technology
Railway truck generally comprises car body, bogie truck, brake equipment and coupler and draft gear etc. and partly forms.Wherein, the device that coupler carrier is connected with car body as hitch, is a part of coupler and draft gear key, and it is mainly used in impact and the friction of carrying the deadweight of hitch and producing in the course of the work.Because coupler carrier frequency of operation is higher, improve its reliability of structure and working stability, under the prerequisite of proof strength, loss of weight is very crucial technology.Traditional coupler carrier is arranged in striker, as shown in Figure 1.Because double system car coupler hook body is shorter, the design of coupler carrier should meet intensity, the rigidity requirement that should meet carrying hitch in narrow space, can guarantee again when hitch, hook tail frame seesaw not bump with coupler carrier.
Utility model content
The purpose of this utility model is the technical matters existing in background technology in order to solve, and the utility model proposes a kind of applicable car body and double system car coupler connecting device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of car body of the present utility model and hitch connecting device, comprise coupler carrier, hitch, central sill;
Coupler carrier comprises joist seat, connecting panel, supporting vertical plate, joist seat inner side is processed with the mounting groove matching with central sill front end profile, the lower end fixed connecting plate of joist seat, on connecting panel, have for the fixing tie bolt hole of central sill, the lower surface of connecting panel is vertically fixed a supporting vertical plate, and two reinforcement gussets are set between supporting vertical plate and connecting panel;
Coupler carrier is fixed on central sill bottom by connecting panel screw, makes the joist seat of coupler carrier as downward supporter; The joist seat of coupler carrier embeds the front end of central sill by mounting groove, carry out located lateral.
Beneficial effect
1, in conjunction with dual-purpose hitch feature, cancel hook tail mount structure, alleviated weight, expanded the forced stroke of double system car coupler, make buffer structure compacter.
2, increase connecting panel, by the lower end carriage of intensity, change the connection location of joist into central sill that intensity is higher, the main loading characteristic of bolt is become to tension state from the state cut simultaneously, reduced danger coefficient, improved reliability and the service life of work.
3, joist seat embeds in central sill, the lateral impact forces producing in the time of can bearing preferably car body curve driving.
4, the layout of supporting vertical plate increases horizontal and vertical area of thrust surface.
5, guaranteeing under the prerequisite of structural strength, joist body front part designed to two larger rectangle blind holes, in its rear design lightening grooves, with the lightweight of implementation structure.
6, between connecting panel and supporting vertical plate, increased and strengthened gusset to improve the ability of joist reliability of structure and carrying vertical force.

The specific embodiment
Below in conjunction with drawings and Examples, content of the present utility model is further described.
Embodiment
A kind of car body of the present utility model and hitch connecting device, comprise coupler carrier 8, hitch 9, central sill 10;
Coupler carrier 8 comprises joist seat 1, connecting panel 2, supporting vertical plate 5, joist seat 1 inner side is processed with the mounting groove matching with central sill front end profile, the lower end fixed connecting plate 2 of joist seat 1, on connecting panel 2, have for the fixing tie bolt hole 3 of central sill, the lower surface of connecting panel 2 is vertically fixed a supporting vertical plate 5, and two reinforcement gussets 7 are set between supporting vertical plate 5 and connecting panel 2;
Coupler carrier 8 is fixed on central sill bottom by connecting panel 2 screws, makes the joist seat 1 of coupler carrier as downward supporter; The joist seat 1 of coupler carrier embeds the front end of central sill by mounting groove, carry out located lateral.
