DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a crane supporting wheel with a buffer structure, comprising a mounting seat 1, a first threaded hole 2 is opened on the mounting seat 1, a buffer spring 3 is connected inside the mounting seat 1, one end of the buffer spring 3 is connected to a connecting rod 4, a fixing ring 5 is connected to the connecting rod 4, one end of the connecting rod 4 is connected to a connecting plate 9, a fixing pin 6 is connected to the fixing ring 5, the fixing ring 5 is rotatably connected to a damper 7 through the fixing pin 6, one end of the damper 7 away from the fixing ring 5 is rotatably connected to the bottom of the mounting seat 1 through the fixing pin 6, a shock-absorbing spring 8 is sleeved on the damper 7, both ends of the shock-absorbing spring 8 are connected to both ends of the damper 7, there are two dampers 7 that are mirror-symmetrical about the axis of the connecting rod 4, the two symmetrically connected dampers 7 and the shock-absorbing spring 8 can be compressed at the same time when the supporting wheel body 14 is impacted, thereby improving the buffering effect of impact force and vibration.

[0023] Connecting frames 10 are connected to both sides below the connecting plate 9, and a smooth rod 11 is connected to the connecting frame 10. The connecting frame 10 and the mounting plate 13 are both U-shaped in design. Second springs 22 are sleeved on both ends of the smooth rod 11. One end of the second spring 22 is connected to the connecting frame 10, and the other end of the second spring 22 is connected to the slider 12. The slider 12 stretches or compresses the second spring 22 to buffer and reduce the impact force on the supporting wheel body 14, thereby preventing the impact force from damaging the supporting wheel body 14.

[0024] A slider 12 is slidably connected to the smooth rod 11, a mounting plate 13 is connected below the slider 12, a roller body 14 is mounted on the mounting plate 13, a slot 23 is provided in the roller body 14, a third threaded hole 24 is provided in the roller body 14, the second threaded hole 15 and the third threaded hole 24 are of the same size and correspond in position to each other, an insert block 20 is inserted into the slot 23, and by inserting the insert block 20 into the slot 23, the staff can easily and quickly complete the positioning and installation of the roller body 14, thereby improving the installation efficiency.

[0025] Grooves 16 are provided inside both sides of the mounting plate 13, and a sliding rod 17 is slidably connected in the groove 16. A pull ring 21 is connected to one end of the sliding rod 17, and the other end of the sliding rod 17 is connected to the connecting block 19. Through the pull ring 21 at one end of the sliding rod 17, the staff can easily pull the sliding rod 17 to move, thereby improving the positioning efficiency of the supporting wheel body 14.

[0026] A first spring 18 is connected to the inside of the groove 16, and a connecting block 19 is connected to one end of the first spring 18. A plug block 20 is connected to the side of the connecting block 19 away from the first spring 18. A second threaded hole 15 is provided on the mounting plate 13 and the plug block 20. The connecting block 19 slides in the groove 16 and fits in contact with the inner wall of the groove 16. The connecting block 19 fits in contact with the inner wall of the groove 16, so that the connecting block 19 can slide smoothly in the groove 16, thereby preventing the plug block 20 from tilting when moving.

[0027] The working principle of the utility model is:

[0028] The staff pulls the pull ring 21 to make the sliding rod 17 pull the connecting block 19 to move into the groove 16. At the same time, the connecting block 19 compresses the first spring 18, so that the plug block 20 enters the groove 16. After the slots 23 on both sides of the supporting roller body 14 are aligned with the plug block 20, the pull ring 21 is released, so that the first spring 18 rebounds and pushes the plug block 20 into the slot 23, thereby connecting and fixing the supporting roller body 14 to the mounting plate 13. At this time, the second threaded hole 15 and the third threaded hole 24 are aligned with each other, which is convenient for the staff to screw the bolt assembly into the second threaded hole 15 and the third threaded hole 24 at the same time. The threaded hole 24 is inserted into the threaded hole 24 to further strengthen the connection and prevent the supporting wheel body 14 from loosening and falling. When the supporting wheel body 14 is subjected to a horizontal impact force, the slider 12 will slide on the smooth rod 11, thereby stretching or compressing the second springs 22 on both sides to buffer the impact force. When the supporting wheel body 14 is subjected to a vertical impact force, the connecting plate 9 will push the connecting rod 4 upward to move the connecting rod 4 to enter the mounting seat 1 to compress the buffer spring 3. At this time, the damper 7 will also rotate, so that the shock-absorbing spring 8 and the damper 7 are compressed together, thereby buffering and reducing the impact force and vibration.
