[0034] Second embodiment of the hook self-rotating busbar lifting frame:

[0035] Referring to Figure 6 and Figure 7 On the basis of the first embodiment of the hook self-rotating busbar lifting frame, the hook self-rotating busbar lifting frame further comprises a tensioning wheel 7 and a tensioning driving device 8. The tensioning wheel 7 is arranged between the driving wheel 5 and the driven wheel 6, and the belt is also arranged on the tensioning wheel 7. The tensioning driving device 8 can drive the tensioning wheel 7 to move linearly, so as to tension or loosen the belt.

[0036] In this embodiment, the moving direction of the tensioning wheel 7 is perpendicular to the line connecting the driving wheel 5 and the driven wheel 6. Specifically:

[0037] A sliding groove 11 is formed in the mounting frame 1, and the length direction of the sliding groove 11 is perpendicular to the line connecting the driving wheel 5 and the driven wheel 6, that is, the line connecting the driving wheel 5 and the driven wheel 6 is parallel to the horizontal direction, and the length direction of the sliding groove 11 is parallel to the up-down direction. An axle pin 71 is slidably arranged in the sliding groove 11, and the axle pin 71 penetrates the sliding groove 11.

[0038] The tensioning driving device 8 is arranged on the mounting frame 1, and the tensioning driving device 8 can be a pneumatic cylinder or a hydraulic cylinder. The driving end of the tensioning driving device 8 is provided with an L-shaped seat 81, the L-shaped seat 81 is fixedly connected with the first end of the axle pin 71, and the tensioning wheel 7 is rotatably sleeved on the second end of the axle pin 71. The tensioning driving device 8 drives the axle pin 71 to move in the sliding groove 11 through the L-shaped seat 81, and in turn drives the tensioning wheel 7 to move up and down. Since the belt is arranged on the tensioning wheel 7, when the tensioning wheel 7 moves away from the line connecting the driving wheel 5 and the driven wheel 6, the belt can be stretched outward to tension the belt, and when the tensioning wheel 7 moves towards the line connecting the driving wheel 5 and the driven wheel 6, the belt can be loosened.

[0039] In order to avoid that the belt is accidentally separated from the tensioning wheel 7 during the movement of the tensioning wheel 7, a groove 72 for accommodating the belt is arranged on the outer peripheral wall of the tensioning wheel 7, the groove 72 extends along the circumference of the tensioning wheel 7, the groove width of the groove 72 is slightly larger than the width of the belt, and the groove depth of the groove 72 is greater than the thickness of the belt.

[0040] After the lifting hook 50 is moved into position, the rotating drive device 4 can drive the hook 3 to overturn upward, and in this process, the belt is in a tensioned state; since the lifting hook 50 is hooked with the hook 3, under the lifting operation of the lifting hook 50, the hook 3 will inevitably rotate by a small angle, and in order to avoid the belt from being broken, when the upper part of the hook 3 enters the entrance of the lifting hook 50, the tensioning wheel 7 promotes the belt to be in a slightly relaxed state, so that the belt can slip between the driven wheel 6.

[0041] Third embodiment of the hook self-rotating busbar lifting frame

[0042] On the basis of the first embodiment of the hook self-rotating busbar lifting frame, the hook self-rotating busbar lifting frame further comprises a tensioning wheel and a tensioning drive device, the tensioning drive device is arranged on the mounting frame, the tensioning wheel is arranged on the drive shaft of the tensioning drive device, and the tensioning wheel is arranged between the driving wheel and the driven wheel, and the belt is also arranged on the tensioning wheel.

[0043] The tensioning wheel of the embodiment is an eccentric wheel, and the tensioning drive device is a motor, and the tensioning drive device can drive the eccentric wheel to rotate around the drive shaft to tension or relax the belt.

[0044] After the lifting hook is moved into position, the rotating drive device can drive the hook to overturn upward, and in this process, the belt is in a tensioned state; since the lifting hook is hooked with the hook, under the lifting operation of the lifting hook, the hook will inevitably rotate by a small angle, and in order to avoid the belt from being broken, when the upper part of the hook enters the entrance of the lifting hook, the tensioning wheel promotes the belt to be in a slightly relaxed state, so that the belt can slip between the driven wheel.

[0045] As can be seen from the above, the hook 320 can automatically overturn upward when needed, which is convenient and easy and fast to hook with the lifting hook 50 of the head sheave, and compared with the prior art, the hook 320 has the advantages of simple structure, convenient operation and improved work efficiency; the utility model does not need workers to operate on high places, can effectively avoid the occurrence of safety accidents, and ensures the personal safety of workers.
