[0031] like Figures 1 to 10 As shown in the figure, when the belt conveyor roller disassembly device of the utility model is used to disassemble the roller to be repaired, it includes the following disassembly steps:

[0032] S0, clean the materials on the belt conveyor 9 that needs to be repaired, shut down the machine, turn off the power, and hang a maintenance sign (not shown in the figure);

[0033] S1, determine the drum 7 to be repaired, and disassemble the drum 7 to be repaired and the accessories connected thereto;

[0034] S2, fix the conveyor belt 1 near the upper section of the roller 7 to be repaired using the clamping tool 2, and the clamping tool 2 is against one side of the fixed frame of the belt conveyor 9;

[0035] S3, fix the lower section of the conveyor belt 1 behind the tensioning device 8 of the belt conveyor 9 with a clamping tool 2, and the clamping tool 2 is pressed against one side of the fixed frame of the belt conveyor 9;

[0036] S4, lift the tensioning device 8 to make the conveyor belt 1 between the tensioning device 8 and the roller 7 to be repaired in a relaxed state;

[0037] S5, using the lifting tool 3 to lift the conveyor belt 1 and separate it from the roller 7 to be repaired;

[0038] S6, using the lifting tool 3 to lift the drum 7 to be repaired;

[0039] S7, the hoisting tool 3 hoists the drum 7 to be repaired to the mobile tool 4, and temporarily stores the drum 7 to be repaired;

[0040] S8, transferring the drum 7 to be repaired to the repair location.

[0041] A plurality of fixing frames are arranged at intervals on both sides of the belt conveyor 9 body.

[0042] When the belt conveyor 9 is located indoors, in step S5 , a plurality of preset hanging points are set on the wall 6 , and the hoisting tool 3 is connected to the preset hanging points.

[0043] The clamping tool 2 includes an upper clamping member 211 and a lower clamping member 212 that are relatively arranged. The upper clamping member 211 and the lower clamping member 212 are connected by a stud 23 and a pad 24. The upper clamping member 211 and the lower clamping member 212 can optionally use square tubes. When clamping and fixing the conveyor belt 1, 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 relatively arranged fixing frames. The upper clamping member 211 and the lower clamping member 212 are against the same side of the two fixing frames. The two relatively 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.

[0044] 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 between the upper clamping member 211 and the conveyor belt 1 .

[0045] Different upper and lower clamping members 211 and 212 can be selected to accommodate different widths and tensions of the conveyor belt 1. By adjusting the distance between the studs 23 of the clamping fixture 2, the clamping fixture 2 can be adapted to different mounting brackets. The entire clamping fixture 2 is connected using studs 23, making installation simple, convenient, and quick, and suitable for a wide range of applications.

[0046] The lifting fixture 3 comprises two opposing lifting frame assemblies and a horizontal slide rail 31. The lifting frame assemblies include an oblique lifting frame and a vertical lifting frame. One end of each of the oblique and vertical lifting frames is hinged to the horizontal slide rail 31, while the other ends of each of the oblique and vertical lifting frames are hinged to the same pre-set hanging point. The horizontal slide rail 31 is equipped with a lifting assembly for lifting the roller to be repaired. A horizontal support member 32 is also installed between the two lifting frame assemblies. When in use, the horizontal support member 32 is hinged to the pre-set hanging point.

[0047] The horizontal support member 32 is hinged to a pre-set hanging point via an upper lifting belt 33. To use, first insert the horizontal support member 32 beneath the conveyor belt 1, then use the upper lifting belt 33 to lift the horizontal support member 32, thereby lifting the conveyor belt 1. Connect the two lifting frame assemblies to the two pre-set hanging points, respectively, and pass the horizontal slide rail 31 beneath the conveyor belt 1. Both lifting frame assemblies are connected to the horizontal slide rail 31.

[0048] The two hanging frame assemblies are defined as a left hanging frame assembly and a right hanging frame assembly respectively. 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 .

[0049] 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.

[0050] 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 turnbuckle bolts 310 , so that the height and angle can be freely adjusted.

[0051] When the lifting 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.

[0052] 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 defined as a left manual hoist and a right manual hoist respectively. 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.

[0053] After lifting the conveyor belt 1, pass the horizontal rail 31 under the conveyor belt 1. The left oblique hoisting frame 341 and the left vertical hoisting frame 342 are hinged to the same preset hanging point at one end via a pin, and the other ends of the left oblique hoisting frame 341 and the left vertical hoisting frame 342 are hinged to the horizontal rail 31. The right oblique hoisting frame 351 and the right vertical hoisting frame 352 are hinged to the same preset hanging point at one end via a pin, and the right oblique hoisting frame 351 and the right vertical hoisting frame 352 are hinged to the horizontal rail 31. The horizontal rail 31 is then adjusted to the appropriate height by adjusting the turnbuckle bolts 310. The hand-pulled rolling trolley 36 is then installed on the horizontal rail 31. The left and right manual hoists 391 and 392 are then installed on the hand-pulled rolling trolley 36. Finally, the lower lifting belt 38 is installed on the left and right manual hoists 391 and 392.

[0054] 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 movement, thereby reducing the occurrence of hidden dangers.

[0055] The movable tooling 4 includes a movable slide rail 42 , on which a movable trolley 43 is slidably arranged.

[0056] Preferably, the upper surface of the movable carriage 43 is provided with a concave arc groove.

[0057] 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.

[0058] Generally, maintenance space is relatively tight. Therefore, to facilitate transportation and installation, the movable rail 42 is divided into two sections and connected with bolts. A block 41 is provided below the movable rail 42. The provision of the block 41 can increase the lateral force-bearing area of ​​the movable rail 42, ensure the horizontality of the movable rail 42, and prevent the movable rail 42 from crushing the conveyor belt 1. Anti-tilt beams are also provided at both ends of the movable rail 42 to effectively prevent the movable trolley 43 from tipping over due to excessive impact when the roller 7 to be repaired falls. The beams also serve as a limiter to prevent the movable trolley 43 from sliding off the movable rail when pushed by hand. The roller 7 to be repaired is temporarily stored on the movable trolley 43.

[0059] Then, the drum 7 to be inspected is moved to the inspection location using a crane (not shown) or the like.

[0060] In the description of this specification, it should be understood that the orientation or positional relationship described in terms of “upper lifting belt”, “lower lifting belt”, etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is 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.
