DETAILED DESCRIPTION

[0022] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, Figure 1 A front view of the structure of the lifting device for replacing the belt of the high-angle belt conveyor; Figure 2 A schematic diagram of the clamping and fixing of the hoisting device for replacing the belt of the high-angle belt conveyor; Figure 3 A structural side view of the lifting device for replacing the belt of a high-angle belt conveyor; Figure 4 This is a side structural sectional view of the lifting device used for replacing the belt of a large-angle belt conveyor.

[0025] The lifting device for replacing the belt of a large-angle belt conveyor described in the utility model includes a fixing frame 1, a clamping part 2 and a supporting part 3. The clamping part 2 and the supporting part 3 are both arranged on the fixing frame 1. The clamping part 2 is used to clamp and fix the two side edges of the belt 4, and the supporting part 3 is used to support the center position of the belt 4.

[0026] Since the belt 4 of the large-angle belt conveyor adopts a skirt tape, a skirt-shaped edging structure is provided between the center and both sides of the cross section of the skirt tape. The utility model clamps and fixes the two side positions of the belt 4 by the clamping part 2, and supports the center position of the belt 4 by the supporting part 3, thereby avoiding the skirt structure of the skirt tape to achieve a good fixing effect. At the same time, the supporting part 3 located at the center position can effectively support the heavy belt 4, and cooperate with the supporting part 3 to clamp and fix the edges of both sides of the belt 4 to prevent slipping, thereby achieving effective fixation of the utility model at the corresponding position of the belt 4, preventing relative sliding of the belt 4 and the lifting device, and accurately lifting by the lifting machine to avoid collision damage between the belt 4 and external facilities. At the same time, the fixed support on both sides and the middle position can also avoid the skirt structure of the skirt tape to protect the skirt structure on the skirt tape.

[0027] Specifically, the fixing frame 1 includes a fixing plate 11, a hanging pipe 12 and a connecting pipe 13. The two fixing plates 11 are symmetrically and fixedly arranged at the two ends of the connecting pipe 13. The two ends of the hanging pipe 12 are detachably connected to the two fixing plates 11 respectively. The supporting part 3 is arranged on the connecting pipe 13, and the clamping part 2 is arranged on the hanging pipe 12. Hanging holes 14 are provided on the two fixing plates 11 for realizing connection and fixation with the hanging machine. The rectangular structure formed by the fixing plate 11, the hanging pipe 12 and the connecting pipe 13 connected to each other ensures the stability of the overall structure of the fixing frame 1.

[0028] The hoisting holes 14 , the hoisting pipes 12 and the connecting pipes 13 are arranged in sequence from top to bottom, so as to facilitate the hoisting and fixing of the belt 4 .

[0029] Preferably, the hanging tube 12 is configured as a hollow tube with a rectangular cross-section, and the fixed plates 11 are each provided with a connecting hole that is matched with the cross-sectional size of the hanging tube 12. The two ends of the hanging tube 12 are respectively arranged in the connecting holes corresponding to the two fixed plates 11, which can ensure that the position of the hanging tube 12 is stable except in the axial direction.

[0030] The end of the hanging tube 12 is provided with a positioning hole, and the positioning hole is set through the hanging tube 12. The two fixing plates 11 are arranged between the two positioning holes. Positioning bolts 15 are provided in the positioning holes. The ends of the positioning bolts 15 pass through the corresponding positioning holes and are threadedly connected with the positioning nuts 16, thereby achieving the fixation of the positioning bolts 15 on the hanging tube 12. The two positioning bolts 15 are respectively clamped with the corresponding fixing plates 11, thereby achieving the stability of the position of the hanging tube 12 in the axial direction.

[0031] The lifting tube 12 is detachable, and the belt 4 can be quickly installed between the lifting tube 12 and the connecting tube 13 by first removing the lifting tube 12 and then placing the belt 4 on the connecting tube 13. The belt 4 can be quickly installed and disassembled on the belt 4 before and after lifting.

[0032] Example 2

[0033] The clamping part 2 includes a clamping rod 21 and a clamping tube 22. The clamping tube 22 is fixed on the fixing plate 11. The clamping rod 21 is set on the lifting tube 12. A clamping block 24 is set at one end of the clamping rod 21 close to the clamping tube 22. The side edge of the belt 4 is set between the clamping block 24 and the clamping tube 22. The clamping operation of the clamping block 24 and the clamping tube 22 on the side edge of the belt 4 is achieved by adjusting the clamping rod 21.

[0034] Specifically, a clamping hole is provided on the hanging tube 12, and the clamping hole is provided through the hanging tube 12. The clamping rod 21 is provided in the clamping hole. A first locking nut 23 is threadedly connected to the clamping rod 21. The first locking nut 23 is provided between the clamping tube 22 and the hanging tube 12. By tightening the first locking nut 23, the first locking nut 23 and the hanging tube 12 are made tightly attached, so that the clamping rod 21 can be pressed down to stably clamp the side edge of the belt 4.

[0035] Generally, two first locking nuts 23 are provided on the same clamping rod 21 to increase the locking force during clamping.

[0036] Preferably, the clamping tube 22 is configured as a hollow tube with a circular cross-section, and the end surface of the clamping block 24 close to the clamping tube 22 is configured as an arc surface, so as to be more conducive to clamping and fixing the belt 4 that is bent by its own gravity during hoisting.

[0037] It is worth noting that the fixing plate 11 is provided with mounting holes corresponding to the clamping tube 22 and the connecting tube 13, so that the ends of the clamping tube 22 and the connecting tube 13 are arranged in the corresponding mounting holes, realizing double-sided welding with a more stable connection state.

[0038] Example 3

[0039] The support portion 3 includes a support plate 31 and a support rod 32, the support plate 31 is connected to the upper end of the support rod 32, the belt 4 is arranged above the support plate 31, and a support hole is provided on the connecting tube 13, and the support hole is set through the connecting tube 13, and the support rod 32 is set in the support hole. A second locking nut 33 is threadedly connected to the support rod 32, and the second locking nut 33 is set between the support plate 31 and the connecting tube 13. By tightening the second locking nut 33, the second locking nut 33 and the connecting tube 13 are tightly attached, so that the support rod 32 can be pushed up to make the support plate 31 stably support the center of the belt 4.

[0040] The fixing structure of clamping at both ends and tensioning in the middle can effectively ensure the tensioning and stable state of the belt 4, thereby improving the connection and fixing effect between the utility model and the belt 4.

[0041] Generally, since the support rod 32 is affected by the gravity of the belt 4, only one second locking nut 33 can be provided on the same support rod 32. Under the action of the gravity of the belt 4, the self-locking of the second locking nut 33 can ensure that the position of the second locking nut 33 on the support rod 32 is stable.

[0042] Preferably, two support rods 32 are provided, and the two support rods 32 are symmetrically arranged at both ends of the support plate 31 to improve the supporting stability of the support rods 32 .

[0043] It is worth noting that the hanging pipe 12 and the connecting pipe 13 are both configured as tubular parts with rectangular cross-sections, thereby effectively improving the fitting stability effect between the first locking nut 23 and the second locking nut 33 and the corresponding hanging pipe 12 and the connecting pipe 13.

[0044] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
