Embodiment Construction

[0025] The embodiment of the present invention provides a guide support device, which is used to be installed under the body of a road-rail dual-use vehicle.

[0026] See figure 1 with figure 2 , The embodiment of the present invention provides a guide support device, including a guide wheel assembly 1 and a support cylinder 2. The guide wheel assembly 1 includes an axle 11 and guide wheels 12 arranged at both ends of the axle 11, which also includes a linkage mechanism 3, a linkage mechanism The two ends of 3 are hinged with the two ends of the axle 11 and the guide wheel 12 respectively, and are used to transmit force parallel to the direction of the axle 11 so that the guide wheels 12 at the two ends of the axle 11 turn in the same direction.

[0027] There are many ways to realize the articulation between the linkage mechanism and the guide wheels at both ends of the axle, which can be the fit between the ball and the spherical cavity; when the linkage structure is a combinatio...

Abstract

The invention provides a guiding support device and a road-rail tractor. The guiding support device comprises a guide pulley assembly and a support cylinder, wherein the guide pulley assembly comprises a wheel axle and guide pulleys arranged at the two ends of the wheel axle; the guiding support device also comprises a linkage mechanism, the two ends of the linkage mechanism are respectively hinged with the guide pulleys arranged at the two ends of the wheel axle, and the linkage mechanism is used for transmitting a force parallel to the direction of the wheel axle, so that the guide pulleys arranged at the two ends of the wheel axle make a turn in a same direction. After the linkage mechanism is arranged, the guide pulleys arranged at the two ends of the wheel axle do not move in an inwards-splayed or outwards-splayed motion form, and just can move in a parallel motion form, in such a way, the running resistance of a vehicle in the process of running is greatly reduced, and the occurrence probability of a derailment phenomenon is reduced, thereby improving the driving safety.

Description

Technical field [0001] The invention relates to rail transportation technology, in particular to a guiding support device and a dual-purpose tractor for road and railway. Background technique [0002] Road and railway dual-purpose tractors refer to tractors that can walk on tracks and travel on roads. It is an auxiliary power vehicle for railway transportation. Road and railway dual-purpose tractors are mainly suitable for small shunting operations in railway stations and towing operations on highways and other special sites; they are also suitable for towing operations in ports, docks and industrial and mining enterprises. [0003] At present, the most commonly used road-rail dual-use vehicle is driven by rubber tires. When the vehicle is walking on the road, rubber tires are sufficient to meet the demand. However, when the vehicle is walking on the rail, the rubber wheel has no guiding function and cannot walk on the rail alone because the rail is narrow and has a certain slope....
