Description

TECHNICAL FIELD

[0001] The present application belongs to the field of wheel-rail equipment driving guide device, in particular to a self-adaptive guide rail type guide device for wheel-rail equipment. BACKGROUND

[0002] When the contemporary wheel-rail equipment such as crane lifts and moves heavy objects or the center of gravity of the wheel-rail equipment is not centered, the end beams at both ends of the girder are unevenly stressed, which causes the equipment to deviate and tilt and the wheels to bite the rails, thus greatly reducing the service life of the equipment wheels. At present, the guide wheels of the guide devices used on various wheel-rail equipment are fixed, but the accuracy error of guide rail adjustment and temperature changes and other factors will cause the guide rail to bend and tilt, especially the guide rail of large-stroke wheel-rail equipment, which will have greater bending and tilting within the full stroke of the guide rail. If both sides of the guide wheel of the guide device are fixed, the guide wheel will be stuck with the guide rail, which will cause the equipment to be unable to move or even damage the drive motor. Therefore, a self-adaptive guide rail type guide device for wheel-rail equipment is proposed, which integrates two guide wheels together and designs one side of the guide wheel as open. The open side guide wheel is pressed against the side of the guide rail by the spring pressure to ensure guidance, and the open side can adapt to the bending and tilting of the guide rail. The spring pressure of the present application can be adjusted to adjust the adaptability of the guide wheel to the bending and tilting of the guide rail, which can effectively ensure the adaptability to guide rails with different bending and tilting degrees. Moreover, the guide device proposed in the present application can share a set of guide rails with the wheel-rail equipment, i.e. it does not need to be separately laid. SUMMARY

[0003] Therefore, the present application aims to provide a self-adaptive guide rail type guide device for wheel-rail equipment to solve the problems and deficiencies of the prior art. Compared with the guide devices of wheel-rail equipment at present, the guide device can realize the freedom of one side of the guide wheel, and always adhere to the guide rail under the action of the spring. Therefore, the guide device can adapt to the bending and tilting of the guide rail of the equipment and can always guide the wheel-rail equipment.

The guide wheel shaft system 3.4 is installed in the holes opened on the fixing frame 3.2 and the sliding frame 3.6, respectively. The guide wheels of the two parts are in close contact with the two sides of the guide rail 2, respectively, to ensure that the wheel-rail device does not derail during operation.

[0038] In a preferred embodiment of the present application, the spring tension assembly 3.3 comprises: a telescopic shaft 3.3.1, a spring body 3.3.2, a guide sleeve 3.3.3, a locking nut 1 3.3.4, an adjusting nut 3.3.5. The shaft 3.3.1 of the spring tension assembly 3.3 is fixedly connected with the sliding frame 3.6 through the adjusting nut 3.3.5 and the locking nut 1 3.3.4; the guide sleeve 3.3.3 is fixedly connected with the fixed frame 3.2, and the telescopic shaft 3.3.1 and the guide sleeve 3.3.3 constitute a moving pair; the spring body 3.3.2 is sleeved on the bottom of the telescopic shaft and abuts against the boss on the bottom of the telescopic shaft 3.3.1, and when the sliding frame 3.6 moves away from the fixed frame 3.2, the spring body 3.3.2 is pressed; the adjusting nut 3.3.5 can be used to adjust the pressure of the spring body 3.3.2 to ensure that the side guide wheels 3.4.6 of the sliding frame 3.6 better fit the guide rail 2; and the locking nut 1 3.3.4 is used to fix the telescopic shaft 3.3.1 and the sliding frame 3.6.

[0039] In a preferred embodiment of the present application, the guide wheel shaft system 3.4 comprises: a shaft body 3.4.1, a buckle cover 3.4.2, a sleeve 3.4.3, a locking nut 2 3.4.4, an angular contact ball bearing 3.4.5, and a guide wheel 3.4.6. The shaft body 3.4.1 is fixedly connected with the fixed frame 3.2 and the sliding frame 3.6 through the anti-rotation pressing piece 3.5 respectively; the inner ring of the angular contact ball bearing 3.4.5 is matched with the shaft body 3.4.1, and the outer ring is matched with the guide wheel 3.4.6, so that the guide wheel 3.4.6 can rotate around the shaft body 3.4.1; the sleeve 3.4.3 is used to separate the two angular contact ball bearings 3.4.5 and can transmit the force therebetween; the buckle cover 3.4.2 is screwed with the guide wheel 3.4.6; and the locking nut 2 3.4.4 is screwed on the thread at the end of the shaft body 3.4.1 to pre-tighten the angular contact ball bearing 3.4.5 and prevent it from falling off.

[0040] The principle on which the self-adapting guide rail type guide device for a wheel-rail type equipment is based is as follows:

[0041] The guide assembly 3 is generally installed in pairs at both ends of the wheel-rail device end beam 1, which can effectively prevent the end beam 1 from tilting during the operation of the device. When the wheel-rail device has a long stroke, the guide rail 2 may tilt or bend due to adjustment errors and temperature changes. When the tilt or bend is towards one side of the sliding frame 3.6, the guide rail 2 presses the guide wheel 3.4.6 on one side, which in turn drives the guide wheel shaft system 3.4 on one side of the sliding frame 3.6 away from the guide rail 2. The guide wheel shaft system 3.4 drives the sliding frame 3.6 to slide away from the guide rail 2 along the key groove on the base plate 3.1 and the fixed frame 3.2. At this time, the telescopic shaft 3.3.1 is fixed on the sliding frame 3.6 by the locking nut 1 3.3.4 and the adjusting nut 3.3.5. The sliding frame 3.6 pulls the telescopic shaft 3.3.1, which slides along the guide sleeve 3.3.3. At this time, the spring body 3.3.2 is under pressure and pulls the sliding frame 3.6. The side guide wheel shaft system 3.4 of the sliding frame 3.6 increases the pressure on the side of the guide rail 2, which provides better guidance for the wheel-rail device. In this way, the guide assembly 3 can adapt to the bending and tilting conditions of the guide rail 2, and the wheels of the wheel-rail device can run along the guide rail 2 without tilting. When the guide rail 2 tilts or bends towards the fixed frame 3.2, the side guide wheel shaft system 3.4 of the fixed frame 3.2 plays a major guiding role. At this time, the spring body 3.3.2 exerts pressure on the telescopic shaft 3.3.1, which pulls the sliding frame 3.6. The side guide wheel 3.4.6 of the sliding frame 3.6 moves towards the guide rail 2 and is pressed tightly, which plays a guiding role. When it is necessary to adjust the spring force of the spring body 3.3.2 to adapt to the bending or tilting of the guide rail 2, the adjusting nut 3.3.5 is adjusted. When it is necessary to adjust the spring force, the hexagonal head at the end of the telescopic shaft 3.3.1 is held with a wrench, the locking nut 1 3.3.4 is loosened, and the adjusting nut 3.3.5 is rotated with a wrench to adjust the telescopic shaft 3.3.1. Then the spring body 3.3.2 is tightened or loosened to achieve the purpose of adjusting the pressure of the spring body 3.3.2. In addition, the spring tension assembly 3.3 is arranged in pairs, which can effectively prevent the telescopic shaft 3.3.1 from being stuck in the guide sleeve 3.3.3.

[0042] The advantages of the present application are as follows:

[0043] 1. The guide device of the present application can adapt to the bending and tilting of the guide rail, which can effectively prevent the guide wheel from being stuck due to the bending or tilting of the guide rail.

[0044] 2. The guide device of the present application can adjust the spring pressure to adapt to the bending or tilting of the guide rail.

[0045] 3. The guiding device of the present application does not interfere with the device for adjusting the guide rail below, is stable in structure and easy to adjust, and can share a set of guide rails with the wheeled walking equipment, and is simple in structure and good in compactness;

[0046] 4. The guiding device of the present application can always ensure that the guiding devices installed on the end beams in pairs press the guide rails on the same side of the guiding wheels, effectively preventing the end beam of the wheel-rail type equipment from tilting to cause the wheel to gnaw the rail.

[0047] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
