Description

Technical Field

[0001] The invention relates to the field of tractors, and in particular to a guide device for a new energy road-rail dual-purpose tractor. Background Art

[0002] The road-rail dual-purpose tractor is a special vehicle widely used in railway dedicated lines and railway vehicle maintenance and manufacturing enterprises. It is mainly used for rail vehicle traction and shunting operations, and can also be used as rail engineering machinery during new line construction and later maintenance. With the development of new energy technology, new energy road-rail dual-purpose tractor locomotives have also been developed. When the tractor is working, it is necessary to set a guide device to match the movement of the guide rail to achieve guidance. However, when the existing new energy road-rail dual-purpose tractor locomotive guide device is in use, most of the guide wheels and the wheel axles do not have the function of fine-tuning the steering. When encountering a small turn in the track, the hard friction between the guide wheel and the track will accelerate wear, and the guide device does not have a shock-absorbing structure for lifting and lowering. Once the guide rail changes partially or the height of the two guide rails changes, one guide wheel will be separated from the guide rail, posing a safety hazard. Therefore, those skilled in the art provide a new energy road-rail dual-purpose tractor locomotive guide device to solve the problems raised in the above background technology. Summary of the invention

[0003] The purpose of the present invention is to provide a new energy dual-purpose road-rail traction vehicle guide device to solve the problems raised in the above-mentioned background technology.

[0008] As a further solution of the present invention: the elastic supporting leather pad and the sealing ring are both made of corrosion-resistant rubber.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] See also Figures 1 to 4 In an embodiment of the present invention, a guide device for a new energy road-rail dual-purpose tractor includes an axle 1 and guide wheels 7 arranged at both ends of the axle 1, a bearing seat 2 is arranged on the periphery of the axle 1 on one side of the guide wheel 7, a movable square rod 10 is fixedly connected to the top of the bearing seat 2, a guide base 9 is slidably connected to the periphery of the movable square rod 10, a lifting hydraulic cylinder 3 is fixedly connected to the top of the guide base 9, a fixing block 5 is fixedly connected to one side wall of the lifting hydraulic cylinder 3, a mounting plate 6 is fixedly connected to the side of the fixing block 5 away from the lifting hydraulic cylinder 3, and a mounting hole 601 for connecting with a new energy road-rail dual-purpose tractor is opened on the periphery of the mounting plate 6; The two ends of the wheel shaft 1 are fixedly connected with a spherical support seat 8 at the guide wheel 7. The inner wall of the guide wheel 7 is provided with a spherical cavity 701 that matches the spherical surface of the spherical support seat 8. The two ends of the spherical support seat 8 on the guide wheel 7 are integrally formed with a limiting boss 702 for limiting, and the gap between the limiting boss 702 and the spherical support seat 8 and the wheel shaft 1 is filled with an elastic support leather pad 13. The elastic support leather pad 13 and the sealing ring are both made of corrosion-resistant rubber. .

[0015] By adopting the above technical solution, it can be installed in the front and rear of the new energy dual-purpose road-rail tractor, and then by controlling the action of the lifting hydraulic cylinder 3, the wheel axle 1 and the guide wheel 7 can be pushed downward, so that the guide wheel 7 is just stuck on the track to achieve guidance, which can ensure the smooth operation of the tractor. By arranging a spherical support seat 8, a guide wheel 7 and an elastic support leather pad 13 between the wheel axle 1 and the guide wheel 7, it can be ensured that the guide wheel 7 can be supported by the spherical support seat 8. It can be ensured that the guide wheel 7 can be fine-tuned at any angle under the support of the track to match the slight turning of the track, which can effectively avoid the hard contact of the guide wheel 7 when the track makes a slight turning, effectively reduce the wear of the guide wheel 7, and improve the durability.

[0016] The wheel axle 1 and the bearing seat 2 are rotatably connected via a double-row roller bearing, which can ensure that the wheel axle 1 can rotate flexibly.

[0017] Among them, an arc groove 902 is opened at the bottom of the side wall of the guide base 9, and a positioning pin 903 is fixedly connected to the side wall of the guide base 9 above the arc groove 902. A limit block 4 for limiting the position that cooperates with the arc groove 902 is fixedly connected to the side wall of the movable square rod 10, which can play a limiting role after the telescopic rod of the lifting hydraulic cylinder 3 is retracted.

[0018] Among them, the telescopic end of the lifting hydraulic cylinder 3 passes through the guide base 9 and is fixedly connected to a fixed block 5-1. There is a gap between the fixed block 5 and the inner hole of the guide base 9. A fixed block 5-2 is fixedly connected in the inner hole of the movable square rod 10. A damping link 11 is fixedly connected between the fixed block 5-1 and the fixed block 5-2. The outer periphery of the damping link 11 is located between the fixed block 5-1 and the fixed block 5-2 and is clamped with a spring 12.

[0019] By adopting the above technical solution, the spring 12 can provide elastic supporting force for the movable square rod 10, and the damping link 11 can provide elastic damping, thereby providing elastic supporting force with damping effect for the cooperation between the guide wheel 7 and the guide rail. This can effectively solve the problem that the guide wheels 7 on both sides cannot contact the guide rails at the same time when the guide rails are partially uneven or the two guide rails are not horizontal, and can ensure that the guide wheels 7 can rotate perfectly close to the guide rails, thereby improving the use effect.

[0020] The working principle of the present invention is: when in use, the guide device is screwed through the mounting hole 601 and then installed in front and rear of the new energy road-rail dual-purpose tractor. Then, the lifting hydraulic cylinder 3 is connected to the reversing valve and then connected to the control console of the new energy road-rail dual-purpose tractor. The reversing valve can be controlled by the control console to control the lifting movement of the lifting hydraulic cylinder 3. When the new energy road-rail dual-purpose tractor moves to the top of the track, the lifting hydraulic cylinder 3 is controlled by the control console to push the wheel axle 1 and the guide wheel 7 to move downward, so that the guide wheel 7 is just stuck on the track to achieve guidance, thereby ensuring the smooth operation of the tractor.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
