[0006] Compared with the prior art, the beneficial effect of the utility model lies in that: This structure changes the connection mode of the original guide wheel and the frame. Through the guide wheel connecting block, the anti-deviation guide wheel is slidably connected to the bottom of the traveling frame, so that the anti-deviation guide wheel automatically adjusts its position by sliding, eliminating the manual adjustment process; and using this soft connection method of the buffer spring, it ensures that the anti-deviation guide wheel remains in contact with the track, prevents the traveling wheel from deviating from the track, and at the same time reduces the vibration of the anti-deviation guide wheel and increases the service life of the anti-deviation guide wheel.

[0007] Further, the traveling frame includes a top connecting plate for connecting the vehicle body, a traveling wheel cover body, and a bottom connecting plate. A rotating shaft is installed on the traveling wheel cover body, and the traveling wheel is connected to the rotating shaft; the bottom connecting plate is located at the bottom of the traveling wheel cover body, and a sliding groove for connecting the guide wheel connecting plate is provided on the bottom connecting plate.

[0008] Furthermore, a slider is provided on the retaining wheel connecting plate, and the slider is embedded in the sliding groove to slide, realizing the sliding connection between the retaining wheel connecting plate and the bottom connecting plate.

[0009] Furthermore, the bottom connecting plate is provided with two side plates, and a buffer spring is fixedly connected to the inner wall of each side plate. The other end of the buffer spring abuts against the outer end face of the retaining wheel connecting plate on the same side, playing a role in preventing deviation. At the same time, when the offset reaches the limit position, the side plate and the buffer spring abut against the anti-deviation retaining wheel to ensure walking safety.

[0010] Furthermore, mounting holes are formed in the retaining wheel connecting plate, and the wheel shaft of the anti-deviation retaining wheel is connected in the mounting holes, enabling the anti-deviation retaining wheel to rotate around the wheel shaft.

[0011] Furthermore, it also includes a cleaning structure installed at the front and rear ends of the walking frame.

The lower part of the sleeve connecting plate fixes the limiting sleeve, and a cleaning block that can move up and down is installed in the limiting sleeve. The lower surface of the cleaning block fits with the upper surface of the track. It cleans the materials on the upper surface of the track, reducing the wear of the walking wheels; the cleaning block automatically moves downward by its own gravity to ensure that the lower surface of the cleaning block always fits with the upper surface of the track.

[0012] Furthermore, the cleaning block is made of wood or a metal block with a hardness less than that of the track to avoid scratching the surface of the track.

[0013] Furthermore, it also includes a buffer. The buffer is horizontally installed at the front or rear end of the walking frame. When the vehicle body hits an external object when walking to the end point, the buffer plays a buffering role.

[0014] Furthermore, the buffer is a buffer block made of polyurethane material. Description of the Drawings

Specific embodiments

[0022] In order to fully understand the purpose, features and effects of the present utility model, the present utility model will be described in detail by means of the following specific embodiments, but the present utility model is not limited thereto.

[0023] As Figures 1 to 5 shown, a track wheel structure provided by the present utility model includes a traveling vehicle frame, a traveling wheel 4, an anti-deviation retaining wheel 6, a retaining wheel connection plate 5 and a buffer spring 12. The top of the traveling vehicle frame is a top connection plate 1 for connecting the vehicle body, the middle of the traveling vehicle frame is a traveling wheel cover 2, a horizontally arranged rotating shaft 21 is installed on the traveling wheel cover 2, and a traveling wheel 4 is installed on the rotating shaft 21. The bottom of the traveling wheel cover 2 is fixed with a bottom connection plate 3, and a horizontally arranged sliding groove 32 is opened on the lower surface of the bottom connection plate 3. In order to improve stability, the sliding groove 32 is preferably a wedge-shaped groove, and the number is preferably two. The upper surface of the retaining wheel connection plate 5 is provided with an upward protruding slide block 51, the shape of the slide block 51 is complementary to the sliding groove 32, and the slide block 51 is installed in the sliding groove 32, so that the retaining wheel connection plate 5 is slidably connected to the bottom connection plate 3. The number of the retaining wheel connection plates 5 is two, and they are symmetrically arranged on both sides of the track 7.

[0024] Side plates 31 are respectively fixed on both sides of the bottom connection plate 3, and a buffer spring 12 is fixedly connected to the inner wall of each side plate 31. The other end of the buffer spring 12 abuts against the outer end face of the retaining wheel connection plate 5. A vertical installation hole is opened on the retaining wheel connection plate 5, the wheel shaft of the anti-deviation retaining wheel 6 is vertically installed in the installation hole, and the wheel surface of the anti-deviation retaining wheel 6 is attached to the side wall of the head of the track 7, so that the anti-deviation retaining wheel 6 travels on the side wall of the head of the track 7. The two anti-deviation retaining wheels 6 are symmetrically arranged with respect to the track 7. Therefore, the anti-deviation retaining wheel 6 provides an outward force at the contact position with the track 7, and the buffer spring 12 provides an inward force, so as to achieve the functions of anti-deviation limit and automatic adjustment.

[0025] In some preferred embodiments, such as Figure 6As shown, it further includes a cleaning structure. The cleaning structure includes a cleaning block 9, a limit sleeve 10, and a sleeve connecting plate 8. The sleeve connecting plate 8 is fixed to the front end or the rear end of the walking frame. The sleeve connecting plate 8 is placed vertically, and the lower part of the sleeve connecting plate 8 is fixed with the limit sleeve 10. The limit sleeve 10 contains a cleaning block 9 that can move up and down. Under the action of its own gravity, the lower surface of the cleaning block 9 always fits with the upper surface of the track 7. During the running of the vehicle body, the cleaning block cleans the materials deposited on the upper surface of the track 7, reducing the wear of the walking wheels 4. Preferably, the cleaning block 9 is a flexible block, a wooden block, or a metal block with a hardness less than that of the track 7 to avoid scratching the surface of the track 7. Preferably, the cleaning block 9 is slightly inclined.

[0026] In some other preferred embodiments, it further includes a buffer 11. The buffer 11 is horizontally installed at the front end or the rear end of the walking frame. When the vehicle body hits an external object when reaching the end point, the buffer 11 plays a buffering role. Preferably, the buffer 11 is a buffer block made of polyurethane material.

[0027] Working principle:

[0028] When the walking wheels 4 walk on the track 7, the two anti-deviation guide wheels 6 are in contact with the side wall of the head of the track 7 at the same time, playing a role in preventing deviation. When the track 7 is deformed, the anti-deviation guide wheels 6 slide horizontally to adapt to the deformation of the track 7. The buffer spring 12 applies a certain pressure to the guide wheel connecting plate 5 to ensure that the anti-deviation guide wheels 6 are tightly attached to the track 7 when the track 7 is deformed, and can provide a certain buffering effect for the anti-deviation guide wheels 6 to reduce vibration and increase the service life of the anti-deviation guide wheels 6.

[0029] Finally, it should be noted that the above-listed are only the preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and its equivalent technologies, they should be considered within the protection scope of the present invention.
