A vertically rotatable coupler and a road-rail car

Abstract

The invention relates to a perpendicularly rotating car coupler and a road-rail vehicle. The perpendicularly rotating car coupler comprises an installation tube, a car coupler assembly, a nut, a slide block, a spiral elevator, a coupler and a motor, wherein a bar-type hole is formed in the side wall of the installation tube; a screw rod of the spiral elevator and the installation tube are coaxially arranged and mounted in the installation tube in a rotatable manner; the nut is in threaded connection onto the screw rod; the screw rod is inserted into a through hole formed in the slide block; the slide block is connected with the nut; a first installation base is also arranged on the slide block; the car coupler assembly comprises a first car coupler, a second car coupler, a second installation base, a support seat, a sleeve arranged on the support seat, a support spring arranged in the sleeve, and a pulley arranged on the top end of the support spring; the first car coupler is connected to one side of the second car coupler; the first car coupler and the second car coupler press against the pulley so as to rotate relative to the second installation base; the first installation base and the second installation base are detachably connected. The height adjustment efficiency of the car coupler is improved, the support strength of the car coupler is enhanced, and the service life of the car coupler is prolonged.

Description

technical field [0001] The invention belongs to the technical field of road-rail cars, and in particular relates to a vertically rotatable coupler and a road-rail car. Background technique [0002] At present, the dual-purpose railway and road vehicles (referred to as road-rail vehicles) are widely used in the rail transportation industry because they can run on both roads and railways. The public railway car is usually used for operations such as railway traction, emergency repair, construction and emergency rescue. Its car body is usually provided with a coupler, and the vehicle is pulled by the coupler. A certain type of coupler can be selected for existing public and railway vehicles. The height of the coupler is usually determined by the height of the coupler of the towed vehicle, mostly 830~890mm from the rail surface. The position of the bolt is slightly adjusted, or the slider moves up and down through the cooperation of the screw and the nut, so that the height of ...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a vertically rotatable coupler and a road-rail car, which is used to solve the problems in the prior art that the height of the road-rail car coupler is difficult to adjust, the degree of automation is low, the service life is short, and the space occupied is large. The adjustment of the height of the coupler is realized electrically. Reduce the amount of labor tasks, improve the height adjustment efficiency of the coupler; enhance the support of the coupler, prolong the service life of the coupler of the road and railway car; the coupler has a compact structure, takes up little space, and is easy to arrange
