Car coupler connecting device

Abstract

The invention discloses a car coupler connecting device. The car coupler connecting device comprises a car coupler connecting device main body and a supporting frame, wherein one end of the supporting frame is fixedly connected with a trailer, and an inclined downward slope part is arranged at the other end of the supporting frame; one end of the car coupler connecting device main body is connected with the trailer by virtue of a connecting hole and a first spindle penetrating through the connecting hole, and a car coupler connecting part connected with the trailer is arranged at the other end of the car coupler connecting device main body; the car coupler connecting device main body is connected with the slope part by virtue of a connecting component, the connecting component comprises a second spindle and elastic components symmetrically arranged at the two sides of the car coupler connecting device main body, the axis of the first spindle is vertical or approximately vertical to the horizontal plane, and a certain included angle is kept between the axis of the second spindle and the axis of the first spindle. The car coupler connecting device disclosed by the invention can be applicable to complicated road changes and safely and efficiently pull and rescue fault rail transit vehicles.

Description

technical field [0001] The invention relates to vehicle engineering equipment, in particular to a coupler connecting device. Background technique [0002] The coupler connection device is located between the trailer and the towed vehicle, and is usually a device used by the trailer to tow the faulty towed vehicle. The existing coupler connection device is mainly directly attached to the tractor by a straight traction rod. The force arm of the traction rod of this coupler connection device is relatively long, and the mass of the coupler itself is large. When one end of this coupler connection device is attached to the tractor, After the other end is connected to the coupler, the coupler is in danger of touching the ground, and due to traffic control, it can only be installed when it is in use, and it needs to be disassembled at any time, which wastes manpower, material resources and time. Especially when the towed vehicle is a tram, the coupler connection device is under com...

Problems solved by technology

The existing coupler connection device is mainly directly attached to the tractor by a straight traction rod. The force arm of the traction rod of this coupler connection device is relatively long, and the mass of the coupler itself is large. When one end of this coupler connection device is attached to the tractor, After the other end is connected to the coupler, the coupler is in danger of touching the ground, and due to traffic control, it can only be installed when it is in use, and it needs to be disassembled at any time, which wastes manpower, material resources and time

Especially when the towed vehicle is a tram, when the vehicle is in a curve, the coupler connection device is stressed, and the torque cannot be released in time, which will easily lead to the derailment of the tram, causing danger
