When the conveyor belt 1 is clamped and fixed, the conveyor belt 1 is located between the upper clamping member 211 and the lower clamping member 212, and the length of the upper clamping member 211 and the lower clamping member 212 is greater than the distance between the two oppositely arranged fixing frames. The upper clamping member 211 and the lower clamping member 212 are against the same side of the two fixing frames, and the two oppositely arranged fixing frames are respectively defined as a left fixing frame 51 and a right fixing frame 52. Under the obstruction of the left fixing frame 51 and the right fixing frame 52, the movement of the conveyor belt 1 can be effectively prevented. .

[0047] Preferably, an upper rubber plate 221 is provided on the lower surface of the upper clamping member 211 , and a lower rubber plate 222 is provided on the upper surface of the lower clamping member 212 , so as to increase the friction force with the conveyor belt 1 .

[0048] According to different widths and tensions of the conveyor belt 1, different upper clamping pieces 211 and lower clamping pieces 212 can be selected, and different fixing frames can be applied by adjusting the distance of the studs 23 of the clamping tool 2. The entire clamping tool 2 is connected by studs 23, which is simple, convenient, and quick to install and has a wide range of applications.

[0049] The lifting tool 3 includes two relatively arranged lifting frame assemblies and a horizontal slide rail 31. The lifting frame assembly includes an oblique lifting frame and a vertical lifting frame. One end of the oblique lifting frame and the vertical lifting frame are both hinged to the horizontal slide rail 31, and the other ends of the oblique lifting frame and the vertical lifting frame are both hinged to the same preset hanging point. The horizontal slide rail 31 is provided with a lifting assembly for lifting the roller to be repaired; a horizontal support member 32 is also provided between the two lifting frame assemblies. When in use, the horizontal support member 32 is hinged to the preset hanging point.

[0050] The horizontal support member 32 is hinged at a preset hanging point through an upper lifting belt 33. When in use, the horizontal support member 32 is first inserted under the conveyor belt 1, and then the upper lifting belt 33 is used to lift the horizontal support member 32, and the conveyor belt 1 is also lifted. The two hanging frame assemblies are respectively connected to the two preset hanging points, and the horizontal slide rail 31 is passed through the lower part of the conveyor belt 1. Both hanging frame assemblies are connected to the horizontal slide rail 31.

[0051] The two hanging frame assemblies are respectively defined as a left hanging frame assembly and a right hanging frame assembly. The left hanging frame assembly includes a left oblique hanging frame 341 and a left vertical hanging frame 342 ; the right hanging frame assembly includes a right oblique hanging frame 351 and a right vertical hanging frame 352 .

[0052] When in use, one end of the left oblique hanging frame 341 and the left vertical hanging frame 342 are hinged to the same preset hanging point through a pin shaft, and the other ends of the left oblique hanging frame 341 and the left vertical hanging frame 342 are respectively hinged to the horizontal slide rail 31; one end of the right oblique hanging frame 351 and the right vertical hanging frame 352 are hinged to the same preset hanging point through a pin shaft, and the right oblique hanging frame 351 and the right vertical hanging frame 352 are respectively hinged to the horizontal slide rail 31.

[0053] The left oblique hanging frame 341, the left vertical hanging frame 342, the right oblique hanging frame 351 and the right vertical hanging frame 352 are all configured as segmented structures and are connected by basket bolts 310, so that the height and angle can be freely adjusted.

[0054] When the hoisting tool 3 lifts the conveyor belt 1, a gap of more than 500 mm is generated between the conveyor belt 1 and the roller 7 to be repaired, leaving enough space for maintenance.

[0055] The lifting assembly includes a hand-pulled rolling trolley 36 arranged on a horizontal slide rail 31, and two manual hoists are relatively arranged below the hand-pulled rolling trolley 36. A lower lifting belt 38 is arranged below each manual hoist. The two manual hoists are relatively arranged and are respectively defined as a left manual hoist and a right manual hoist. The two lower lifting belts 38 lift the roller 7 to be repaired. After lifting the roller 7 to be repaired, the hand-pulled rolling trolley 36 is manually pulled to move the roller 7 to be repaired out.

[0056] After the conveyor belt 1 is lifted, the horizontal slide rail 31 is passed through the bottom of the conveyor belt 1. One end of the left oblique hanging frame 341 and the left vertical hanging frame 342 are hinged to the same preset hanging point through a pin shaft, and the other ends of the left oblique hanging frame 341 and the left vertical hanging frame 342 are respectively hinged to the horizontal slide rail 31; one end of the right oblique hanging frame 351 and the right vertical hanging frame 352 are hinged to the same preset hanging point through a pin shaft, and the right oblique hanging frame 351 and the right vertical hanging frame 352 are respectively hinged to the horizontal slide rail 31. Then, by adjusting the basket bolt 310, the horizontal slide rail 31 is adjusted to a suitable height, and the hand-pulled rolling trolley 36 is installed on the horizontal slide rail 31, the left manual hoist 391 and the right manual hoist 392 are installed on the hand-pulled rolling trolley 36, and the lower lifting belt 38 is installed on the left manual hoist 391 and the right manual hoist 392.

[0057] Removable limiters 37 are also provided at both ends of the horizontal slide rail 31 to prevent the hand-pulled rolling trolley 36 from derailing during the movement, thereby reducing the occurrence of hidden dangers.

[0058] The movable tooling 4 comprises a movable slide rail 42 , on which a movable trolley 43 is slidably arranged.

[0059] Preferably, the upper surface of the moving trolley 43 is provided with a concave arc groove.

[0060] Further preferably, a wooden wedge 44 is provided on the upper surface of the movable trolley 43, and the use of the wooden wedge 44 can effectively prevent the drum 7 to be repaired from shaking.

[0061] Generally, the maintenance space is relatively tight, so for the convenience of transportation and laying, the movable slide rail 42 is divided into two sections and connected by bolts. A pad 41 is set below the movable slide rail 42. The setting of the pad 41 can increase the lateral force-bearing area of ​​the movable slide rail 42, ensure the horizontality of the movable slide rail 42, and prevent the movable slide rail 42 from crushing the conveyor belt 1. Anti-tilting crossbeams are also set at both ends of the movable slide rail 42, which can effectively prevent the movable trolley 43 from tipping over due to excessive impact when the roller 7 to be repaired falls. The crossbeam can also play a role of limiting, preventing the movable trolley 43 from sliding out of the movable slide rail when the movable trolley 43 is pushed by hand.

[0062] Then, the drum 7 to be inspected is moved to the inspection site using a crane (not shown in the figure) or the like.

[0064] Combination Fig.11 as well as Fig.12 As shown together, when the belt conveyor 9 is located outdoors, in step S5 , the lifting tooling includes a crane, a horizontal support member 32 , and an upper lifting belt 33 .

[0065] As in the first embodiment, the drum 7 to be repaired is disassembled from other accessories.

[0066] As in the first embodiment, after the conveyor belt 1 is fixed by the clamping tool 2, the horizontal support member 32 is passed under the conveyor belt 1, two upper lifting belts 33 are hung on the horizontal support member 32, and the upper lifting belts 33 are lifted by a crane to separate the conveyor belt 1 from the roller 7 to be repaired. The roller 7 to be repaired is lifted by a crane to the mobile trolley 43 for temporary storage.

[0067] Finally, the drum 7 to be inspected is moved to the inspection location using a crane or the like.

[0068] The rest is the same as in the first embodiment.

[0069] In the description of this specification, it is necessary to understand that the orientations or positional relationships described in the “upper lifting belt”, “lower lifting belt”, etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
