Background
The rail and road dual-purpose traction locomotive is a kind of traffic equipment used on the rail and general road, it can advance on the rail and draw the rail carriage, also can run on the road. The two running modes of the road and the railway of the rail dual-purpose traction locomotive are that a common rubber wheel is used as a driving wheel, the difference is that a guide wheel is required to guide on a steel rail when the rail dual-purpose traction locomotive runs, and the guide wheel usually adopts a lifting mechanism to realize the lifting purpose. The existing guide wheel lifting mechanisms directly support cylindrical axles, and because the cross sections of the axles are circular, the contact area between a lifting arm and the axles in the lifting mechanism is small in the supporting process, the mechanical efficiency of the lifting mechanism is low, and the quick wear maintenance cost of the lifting arm and the axles is high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to foretell problem, provide a dual-purpose traction engine leading wheel hoisting device of rail way.
In order to achieve the above object, the utility model discloses a technical scheme be: a guide wheel lifting device of a rail-road dual-purpose traction locomotive comprises guide wheels, axles, lifting arms and a hydraulic cylinder, wherein a sleeve is fixedly connected to the outer part of the axle between the guide wheels, the sleeve is in a rectangular tube shape, and the outer surface of the axle is tangent to the inner surface of the sleeve; the lifting arm is provided with a bearing frame, and the bearing frame can be matched with the sleeve; the lifting arm is arranged in the guide frame and can slide up and down in the guide frame, and pin holes are formed in the upper ends of the guide frame and the lifting arm.
Preferably, the cylinder body of the hydraulic cylinder is arranged on the rail and road dual-purpose traction locomotive body in a hinged mode, the guide frame is adjacent to the hydraulic cylinder and fixed on the rail and road dual-purpose traction locomotive body, and the end part of the piston of the hydraulic cylinder and the lower end of the lifting arm are fixedly connected with the positioning plate.
Preferably, the positioning plate is positioned below the axle.
Preferably, the guide wheels are provided at both ends of the axle.
Compared with the prior art, the utility model discloses an advantage lies in with positive effect:
compared with the prior art, the lifting device is utilized to lift the guide wheel, (1) the lifting arm in the guide wheel lifting mechanism is contacted with the rectangular tubular sleeve, the contact area is large, the operation stability is strong, and the mechanical efficiency is high; (2) because the rectangular tubular sleeve and the lifting arm almost have no relative movement, the abrasion degree is small in the same service time, the service time is long, and the maintenance cost is reduced.

Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.
Example 1
The present invention will be further described with reference to fig. 1-4, and the guide wheel lifting device of the rail dual-purpose traction vehicle shown in fig. 1 comprises guide wheels 7, an axle 4, a lifting arm 1 and a hydraulic cylinder 2, and is characterized in that a sleeve 5 is fixedly connected to the outer part of the axle 4 between the guide wheels 7, the sleeve 5 is rectangular tube-shaped, and the outer surface of the axle 4 is tangent to the inner surface of the sleeve 5, as shown in fig. 3; as shown in fig. 2, the lifting arm 1 is provided with a carrying frame 6, and the carrying frame 6 is adapted to cooperate with the sleeve 5. The positioning plate 8 is located below the axle 4. Guide wheels 7 are provided at both ends of the axle 4.
The lifting arm 1 is arranged in a guide frame 9 and can slide up and down in the guide frame 9, and the guide frame 9 and the upper end of the lifting arm 1 are provided with pin holes 10, which are shown in figures 1, 2 and 4. When the lifting arm is at the lowest position in the guide frame 9, the guide wheel 7 is in contact with the track, meanwhile, pin holes 10 at the upper ends of the lifting arm 1 and the guide frame 9 are aligned, and a pin shaft is inserted into the pin holes 10, so that the guide wheel 7 stably moves on the steel rail; when the lifting arm 1 is at the highest position of the guide frame 9, the guide wheel 7 is separated from the track, and the traction vehicle runs away from the steel rail at the moment.
