Embodiment Construction

[0020] like figure 1 As shown, the coupler buffer device of this embodiment consists of: an impact seat, a front slave plate seat 1, a rear slave plate seat 2, a coupler frame 4, a rectangular opening 7 for the impact seat to be inserted and fixed is opened in the middle of the end beam 6, and the coupler frame 4 Welding and fixing on the inner side of the end beam 6 of the rectangular opening 7 and at the same time welding and fixing with the draw beam 3, the impact seat is fixed on the front end of the rectangular opening 7 in the middle of the end beam 6 through high-strength bolts 9, and the coupler restoring device is placed in the coupler frame 4, The two ends of the coupler recovery device are opposed to the inner wall of the coupler frame through the two side plates of the impact seat 8. The front plate base 1 and the rear plate base 2 are riveted and fixed on the traction beam 3 along the longitudinal direction. The buffer is placed between the front plate base and the...

Abstract

The invention relates to a mounting structure of a car-coupler shock absorber. The mounting structure comprises an impacting seat, a front slave plate seat, a rear slave plate seat and a car-coupler frame. A rectangular opening is formed in the middle of an end beam, the car-coupler frame is welded and fixed on the end-beam inner side of the rectangular opening, the impacting seat is fixed at the rectangular opening of the end beam, a car-coupler return mechanism is placed in the car-coupler frame, two ends of the car-coupler return mechanism are abutted against the inner wall of the car-coupler frame, the front slave plate seat and the rear slave plate seat are longitudinally fixed on a towing beam, the shock absorber is disposed between the front slave plate seat and the rear slave plate seat, a supporting plate used for supporting the shock absorber is fixed below the towing beam, a mounting hole is formed in an iron floor, and a towing pin penetrates the mounting hole to connect a car coupler with the shock absorber. The car-coupler frame is fixed on the rear side of the end beam, the car-coupler return mechanism is placed in the car-coupler frame; the towing pin penetrates the shock absorber and the car coupler from top to bottom, so that the towing pin is prevented from shedding caused by vibration, and accidents like unhooking are avoided; a layer-stepping wearing plate is designed to facilitate maintenance.

Description

technical field [0001] The invention relates to an installation structure of a coupler buffer device, in particular to an installation structure of a WILLISON coupler buffer device, and belongs to the technical field of railway vehicle couplers. Background technique [0002] The coupler buffer device is one of the most basic and important parts of a vehicle. It is located between a locomotive and a vehicle or between a vehicle and a vehicle. It is used to realize mutual coupling, transmit traction or compression force and ease longitudinal impact. [0003] With the increasing export of domestic railway passenger cars, in order to meet the connection with foreign passenger cars, it is necessary to use the same coupler as that on the foreign line, which requires the design of a new structure to meet the interface relationship of the foreign line coupler. WILLISON couplers have been widely used on railway passenger cars in the United States and other countries since the First W...
