Aligning mechanism for vehicle couplers of rail vehicles and vehicle rescue method

Abstract

The invention discloses an aligning mechanism for vehicle couplers of rail vehicles and a vehicle rescue method. The aligning mechanism for the vehicle couplers comprises a cam disc, a first telescopic rod, a second telescopic rod and a third telescopic rod; the cam disc is used for being fixedly connected with a vehicle coupler buffer shell; the first telescopic rod is arranged on one side of thecam disc and used for driving the cam disc to rotate anticlockwise; the second telescopic rod is arranged on the other side of the cam disc and used for driving the cam disc to rotate clockwise; andthe third telescopic rod is arranged between the first telescopic rod and the second telescopic rod and used for keeping the center lines of the vehicle couplers and the center lines of vehicle bodiesbeing aligned; a first notch, a second notch and a third notch are formed in the peripheral surface of the cam disc; when the cam disc rotates anticlockwise, the first notch is engaged with the extending end of the first telescopic rod; when the cam disc rotates clockwise, the second notch is engaged with the extending end of the second telescopic rod; and when the center lines of the vehicle couplers and the center lines of the vehicle bodies are aligned, the third notch is engaged with the extending end of the third telescopic rod. The technical problem of automatic coupling of the vehiclecouplers on a small-radius curve is solved.

Description

technical field

[0001] The invention relates to a rail vehicle coupler centering mechanism and a vehicle rescue method, belonging to the technical field of rail vehicles. Background technique

[0002] Generally, the coupler of tram and subway projects is equipped with a centering device that cannot rotate automatically, such as the Chinese utility model patent CN201120010340.4, the horizontal rotation of the coupler is less than ±15°, and the cam and the coupler rotate together to push the roller out of the groove of the cam. The piston rod of the air cylinder reversely compresses the disc spring, thereby providing a greater counter-rotational moment to return the coupler to the alignment of the centerline and the longitudinal centerline of the car body.

[0003] The main function of the centering device is to prevent the coupler from swinging horizontally and causing interference between the coupler, the hood and the shroud when the train is in the waiting state.

Examples

Embodiment 1

[0048] A rail vehicle coupler centering mechanism, such as Figure 2-4As shown, it includes a coupler buffer housing, a cam disc 6, a first cylinder 1, a second cylinder 2, a third cylinder 3, a cylinder piston rod 4 and a cylinder roller 5. The cam plate is connected with the coupler buffer housing through key grooves, fasteners and other components, so that the cam plate rotates to drive the coupler to rotate. The air duct of the vehicle inflates the corresponding cylinder to control the cylinder piston rod 4 to move forward. When the cylinder was in the non-ventilated state, the return spring in the cylinder moved the cylinder piston rod 4 backwards to reset, so that the cylinder roller and the cam disc were separated.

[0049] The cam plate 6 is fixedly connected with the coupler buffer housing 17 through key grooves and fasteners.

[0050] A first notch, a second notch and a third notch are provided on the outer peripheral surface of the cam disc 6 , and the sidewalls o...

[0058] A coupler centering mechanism, such as Figure 7-10 shown, which includes

[0059] Internal gear cam disc 32, which is used to be fixedly connected with the coupler buffer housing;

[0060] An external gear transmission mechanism 31, which is engaged with the internal gear cam disc 32 for transmission; and

[0061] A driving device, which is used to drive the external gear transmission mechanism 31 and / or the internal gear cam disc 32 to rotate an angle;

[0062] The internal gear cam disc 32 and / or the external gear transmission mechanism 31 are provided with a notch, and the outer side of the internal gear cam disc 32 is provided with a telescopic rod for keeping the center line of the coupler and the center line of the vehicle body in alignment;

[0063] When the telescopic rod stretches out, it cooperates with the notch, and the internal gear cam plate 32 and / or the external gear transmission mechanism 31 are locked together with the telescopic rod; The notch dis...
