[0032] In this embodiment, the housing 1 maintains the cooperation of various components to ensure normal operation of the equipment. When the equipment is working, the driver 2 provides power to rotate the rotating wheel 3, thereby transmitting the rotation of the shaft. When braking is required, the brake push rod 5 is controlled to move, causing the brake push rod 5 to drive the control frame 7 to move. The control frame 7 cooperates with the brake pin 6 through the first inclined pin 8. With the brake box 4 being stable, the first inclined pin 8 is inserted into the corresponding inclined groove 10. Through the inclined structure, the brake pin 6 is pushed to move, so that the brake pin 6 cooperates with the rotating wheel 3 to stop the brake wheel and perform braking. When releasing the brake, the brake push rod 5 drives the control frame 7 to reset, causing the first inclined pin 8 to leave the inclined groove 10, and the second inclined pin 9 will be inserted into the corresponding inclined groove 10 on the other side. Through the inclined structure, the brake pin 6 is moved away from the rotating wheel 3, controlling the operation of the braking structure.

[0033] More specifically, the rotating wheel 3 is made to work stably by cooperating with the rotating inner wheel 11, the rotating outer wheel 12 and the rolling ball 13. During operation, lubricating oil is added to the oil box 14 to maintain the equipment. Under the guidance of the oil guide chamber 15 and the diversion chamber 16, the lubricating oil is introduced into the equipment and diverted into two streams, which flow out from different oil outlets 17 to apply oil to the outer end of the rotating outer wheel 12 and the gap between the rotating outer wheel 12 and the rotating inner wheel 11, thereby maintaining the rotating wheel 3.

[0034] Please see Figure 1 As one implementation method for handling the empty stroke: the driver 2 is provided in two sets, which are distributed on both sides of the housing 1 and are arranged opposite to each other, and both cooperate with the rotating outer wheel 12.

[0035] Specifically, by cooperating with two sets of drivers 2, the worm gear and worm 18 are driven synchronously from both ends, thus solving the problem of empty travel during rotation.

[0036] Please see Figure 2 As a further implementation of the driver: the output end of the driver 2 is provided with a worm gear 18, the outer side of the rotating outer wheel 12 is a worm wheel structure, and the rotating outer wheel 12 cooperates with the worm gear 18.

[0037] Specifically, the driver 2 controls the rotation of the worm 18, causing the worm 18 to engage with the outer wheel with the outer wheel structure, thereby transmitting the worm gear of the worm 18.

[0038] Please see Figures 2-3 As a further embodiment of the brake box: the brake box 4 is provided with a sliding groove 19 and a contraction groove 20, the sliding groove 19 and the contraction groove 20 are connected, the control frame 7 cooperates with the sliding groove 19, and the brake pin 6 cooperates with the contraction groove 20.

[0039] Specifically, the control frame 7 moves stably through the guide of the sliding groove 19, and the brake pin 6 moves stably through the guide of the contraction groove 20, thereby ensuring a stable engagement between the brake pin 6 and the control frame 7.

[0040] Please see Figures 2-3 As a further embodiment of the brake pin: the front end of the brake pin 6 is provided with a pressure block 21, the front end of the pressure block 21 is provided with a brake pad 22, and the brake pad 22 cooperates with the rotating outer wheel 12.

[0041] Specifically, when the brake pin 6 is working, it pushes the pressure block 21 to move. The pressure block 21 provides pressure, which contacts the rotating outer wheel 12 through the brake pad 22. The uneven structure on the surface of the brake pad 22 makes close contact with the rotating outer wheel 12. Under the pressure of the pressure block 21, the braking efficiency is ensured.

[0042] Please see Figures 4-5As a further embodiment of the oil filling box: the oil filling box 14 is provided with an oil filling hole 23, and a filter screen 24 is provided in the oil filling hole 23.

[0043] Specifically, during oil filling, the lubricating oil is guided by the oil filling hole 23 to flow and is filtered through the filter screen 24 to keep the lubricating oil clean.

[0044] Please see Figure 5 As a further implementation of the filter screen: one end of the oil filling box 14 is provided with a pull-out port 25, and a pull-out frame 26 is slidably connected in the pull-out port 25, and the filter screen 24 is disposed in the pull-out frame 26.

[0045] Specifically, by controlling the pull-out frame 26 to move along the pull-out opening 25, the pull-out frame 26 can be pulled out from the pull-out opening 25, and the filter screen 24 can be pulled out together, making it convenient to clean the filtered waste.

[0046] Please see Figure 2 As a further embodiment of the housing: a sliding rod 27 is provided at one end of the housing 1, and an oiling brush 28 is provided at one end of the sliding rod 27. The oiling brush 28 is engaged with the oil outlet 17.

[0047] Specifically, during oiling maintenance, the oiling brush 28 is moved to make the oiling lubricant contact the outer side of the rotating outer wheel 12. When the oil outlet 17 drips oil onto the outer side of the rotating wheel 3, it will be evenly spread by the oiling brush 28.

[0048] In summary, during the use or operation of the overall equipment:

[0049] The housing 1 maintains the coordination of various components, ensuring normal operation of the equipment. During operation, the driver 2 provides power, controlling the rotation of the worm gear 18. This worm gear 18 engages with the outer wheel with its outer structure, transmitting power through the worm wheel 18 and the rotating wheel 3, thus driving the shaft rotation. When braking is required, the brake push rod 5 is activated, driving the control frame 7 to move. The control frame 7 engages with the brake pin 6 via the first inclined pin 8. With the brake box 4 secured, the first inclined pin 8 inserts into the corresponding inclined groove 10, pushing the brake pin 6 through the inclined structure. Guided by the sliding groove 19, the control frame 7 moves stably. Guided by the contraction groove 20, the brake pin 6 moves stably, ensuring a stable engagement between the brake pin 6 and the control frame 7, allowing the brake pin 6 to push the brake wheel 6. The pressure block 21 cooperates with the rotating wheel 3, and the pressure block 21 provides pressure. It contacts the rotating outer wheel 12 through the brake pad 22. The uneven structure on the surface of the brake pad 22 makes close contact with the rotating outer wheel 12. Under the pressure of the pressure block 21, the braking efficiency is ensured, and the brake wheel is pressed against it to perform braking. When it is necessary to release the brake, the control frame 7 is reset by the brake push rod 5, so that the first inclined pin 8 leaves the inclined groove 10. The second inclined pin 9 will be driven by the control frame 7 to insert into the corresponding inclined groove 10 on the other side of the brake pin 6. Through the inclined structure, the brake pin 6 is moved away from the rotating wheel 3 and positioned to control the operation of the braking structure. Moreover, through the cooperation of two sets of drivers 2, the worm gear and worm 18 are driven synchronously from both ends, making the rotation of the rotating wheel 3 more stable. In addition, during the rotation, the cooperation of the two sets of drivers 2 also solves the problem of empty stroke during the rotation.

[0050] During operation, the inner wheel 11, outer wheel 12, and ball bearing 13 work together to ensure stable operation of the rotating wheel 3. When maintenance is required, the rotation of the equipment is not stopped; instead, the rotating wheel 3 is controlled to operate at a slower speed to add lubricating oil to the oil box 14 for maintenance. The lubricating oil flows through the oil filling hole 23 and is filtered through the filter screen 24 to keep it clean. Guided by the oil guide chamber 15 and the diversion chamber 16, the lubricating oil is introduced into the equipment and diverted into two streams, exiting from different outlets. Oil flows out from the oil outlet 17, applying oil to the outer end of the rotating outer wheel 12 and the gap between the rotating outer wheel 12 and the rotating inner wheel 11, thereby maintaining the rotating wheel 3. Moreover, during oiling maintenance, the oiling brush 28 is controlled to move so that the oiling brush contacts the outer side of the rotating outer wheel 12. When oil drips from the oil outlet 17 onto the outer side of the rotating wheel 3, it is spread evenly by the oiling brush 28. In addition, by controlling the pull-out frame 26 to move along the pull-out opening 25, the pull-out frame 26 can be pulled out from the pull-out opening 25, and the filter screen 24 can be pulled out together, making it convenient to clean the filtered waste.

For all the fixed connections mentioned above, welding is preferred.
