[0002] In coal conveying systems, the conveyor roller is a key component, and the efficiency and safety of its disassembly, assembly, and maintenance directly affect the operational stability of the entire conveying system. However, in the process of disassembling and assembling the roller using existing technologies, the inventors discovered the following problems:
[0003] The prior art discloses a belt conveyor drum alignment device (202310778430.5), which includes a support beam, a drum, and a support plate. The drum is mounted on the top of the support beam via bearings. A fixed column is fixedly connected to the bottom center of the support beam. The fixed column is rotatably connected to the support plate. The four bottom corners of the support beam are detachably connected to the support plate. A telescopic mechanism is provided between the lower front of the support beam and the support plate. The telescopic mechanism is located at a non-middle position at the bottom of the support beam.
[0004] Existing technologies use bearings to limit the roller's position, and bolts to limit the bearings. During disassembly and assembly, it takes a long time to rotate the bolts, wasting the time and effort of the workers. Furthermore, when removing one bearing, there is no limit at one end of the roller, which may make it more difficult to remove the bearing on the other side. Therefore, existing technologies have certain drawbacks.
[0005] In view of this, this utility model is proposed. Utility Model Content
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A coal conveyor roller disassembly and assembly auxiliary device includes:
[0008] The support plate has a support frame fixedly installed on the bottom wall and the front and back walls. There are two bearings on the top of the support plate, and a roller is set between the two bearings.
[0009] The limiting device includes two limiting boxes fixedly installed on the front and rear sides of the top wall of the support plate. Each limiting box has a limiting plate inside its cavity. Each limiting box on the left and right sides is provided with a limiting strip at the side that is far away from each other. Each supporting plate has two connecting holes at the front and rear sides of the top wall.
[0010] The lifting device includes a lifting plate. A lifting groove is provided on the top wall of the support plate. The lifting plate is located in the cavity of the lifting groove. The lifting plate is arc-shaped. Multiple drive grooves are provided at equal intervals on the top wall of the lifting plate. A rubber roller is provided in the cavity of each drive groove.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0032] like Figure 1 As shown, a coal conveyor roller disassembly and assembly auxiliary device includes:
[0033] A support plate 12 has a bearing frame 13 fixedly installed on the front and rear sides of the bottom wall of the support plate 12. There are two bearings 11 on the top of the support plate 12, and a roller 10 is set between the two bearings 11.
[0034] The limiting device includes two limiting boxes 16 fixedly installed on the front and rear sides of the top wall of the support plate 12. Each limiting box 16 has a limiting plate 18 in its cavity. Each limiting box 16 on the left and right sides is provided with a limiting strip 19 on the side that is far away from each other. Each supporting plate 12 has two connecting holes 15 on the front and rear sides of the top wall.
[0035] The lifting device includes a lifting plate 14. A lifting groove 35 is provided on the top wall of the support plate 12. The lifting plate 14 is located in the cavity of the lifting groove 35. The lifting plate 14 is arc-shaped. Multiple drive grooves 20 are provided at equal intervals on the top wall of the lifting plate 14. A rubber roller 26 is provided in the cavity of each drive groove 20. Two electric cylinders 23 are provided below the lifting plate 14.
[0036] It is worth noting that the roller 10, bearing 11, support plate 12 and bearing frame 13, as well as their specific usage methods, have been disclosed in a belt conveyor roller alignment device (202310778430.5), and will not be repeated here.
[0037] In practical use, the existing technology limits the roller 10 by two bearings 11. The limiting device can limit the bearing 11 by inserting the lower ends of the bearing 11 into the cavity of the limiting box 16, and then moving the limiting plate 18 and limiting the limiting plate 18 by the limiting strip 19, thereby limiting the roller 10. The lifting device can use the lifting plate 14 to fit against the bottom wall of the roller 10. When the bearing 11 is separated from the roller 10, the lifting plate 14 limits the roller 10. Then, the rotation of multiple rubber rollers 26 drives the roller 10 to move, so that the workers can remove the roller 10 one by one.
[0038] In summary, by setting a limiting device and a lifting device, the bearing 11 can be limited by the limiting device, which in turn limits the roller 10, making it easy to disassemble and assemble the bearing 11. The roller 10 can be limited by the lifting device, allowing the operator to remove the roller 10. It is convenient to use and has a simple structure.
[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the top walls of the multiple limiting boxes 16 are all hollowed out, and a first through hole 17 is provided on the side wall of the left and right corresponding limiting boxes 16 that are far apart from each other. The limiting plate 18 is inserted into the cavity of the limiting box 16 through the first through hole 17.
[0040] Multiple corresponding limiting strips 19 penetrate through the corresponding limiting plate 18 and are movably connected to the penetration point of the limiting plate 18. The limiting strips 19 are also inserted into the corresponding connecting hole 15 cavity, and the bottom end of the bearing 11 is located below the limiting plate 18.
[0041] In practical use, when the operator inserts the lower ends of the bearing 11 into the corresponding cavity of the limiting box 16, the limiting plate 18 can be inserted into the cavity of the limiting box 16 through the first through hole 17, so that the bottom wall of the limiting plate 18 fits against the lower top wall of the bearing 11, thereby limiting the bearing 11. Then, the limiting strip 19 passes through the limiting plate 18 and is inserted into the cavity of the connecting hole 15 to prevent the limiting plate 18 from moving. Thus, the limiting plate 18 completes the limiting of the bearing 11. During disassembly and assembly, only the limiting strip 19 and the limiting plate 18 need to be moved.
[0042] In summary, by setting up the bearing 11, the limiting box 16, the first through hole 17, the limiting plate 18, the limiting strip 19, and the connecting hole 15, the bearing 11 can be limited by moving the limiting plate 18 and the limiting strip 19, and the bearing 11 can be prevented from moving by the limiting plate 18. This saves time for the staff, is convenient to use, and has a simple structure.
[0043] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a base plate 22 is fixedly installed on the bottom wall of the lifting plate 14. The bottom wall of the base plate 22 is fixedly connected to the movable ends of two electric cylinders 23. Multiple electric cylinders 23 are equally spaced on the left and right side walls of the lifting plate 14. Multiple second through holes 24 are interconnected with the corresponding drive grooves 20.
[0044] A through rod 27 is fixedly installed on the left and right side walls of the multiple rubber rollers 26. The through rod 27 passes through the corresponding second through hole 24 and is movably connected to the through point of the second through hole 24. A limiting post 25 is fixedly installed on the right side wall of the lifting plate 14. The right side wall of the multiple through rods 27 on the right side is rotatably connected to the left side wall of the limiting post 25.
[0045] Two pulleys 28 are fixedly installed on the side wall of each of the multiple through rods 27 in the middle left side, and one pulley 28 is fixedly installed on the side wall of each of the foremost and last left through rods 27. A belt 29 is movably installed between each of the two corresponding pulleys 28.
[0046] A limiting frame 30 is provided on the left side wall of the lifting plate 14. Two connecting strips 31 are fixedly installed on the right side wall of the limiting frame 30, and both connecting strips 31 are fixedly connected to the left side wall of the lifting plate 14. A servo motor 32 is fixedly installed inside the cavity of the limiting frame 30, and the output end of the servo motor 32 is fixedly connected to the corresponding through rod 27. Both the electric cylinder 23 and the servo motor 32 are electrically connected to the power supply and switch.
[0047] In practical use, the extension and retraction of the movable end of the electric cylinder 23 drives the base plate 22 to move upward. The movement of the base plate 22 drives the lifting plate 14 to move. The movement of the lifting plate 14 allows its top wall and the side wall of the rubber roller 26 to fit against the bottom wall of the roller 10. The limit frame 30 and the connecting strip 31 can both limit the servo motor 32. When the output end of the servo motor 32 rotates, it drives the corresponding through rod 27 to rotate. The rotation of the through rod 27 drives the two corresponding pulleys 28 to move forward. When the rollers rotate, the output ends of the two corresponding pulleys 28 can drive multiple pulleys 28 and through rods 27 to rotate via belt 29. The rotation of multiple through rods 27 can drive multiple rubber rollers 26 to rotate. The drive groove 20 can limit the rubber rollers 26, and the second through hole 24 can limit the through rods 27. When the rubber rollers 26 rotate, they can drive the roller 10 to move. The limiting post 25 can also limit the through rods 27, and the lifting groove 35 can limit the lifting plate 14.
[0048] In summary, by setting up drive slots 20 and 21, base plate 22, electric cylinder 23, second through hole 24, limit post 25, rubber roller 26, through rod 27, pulley 28, belt 29, limit frame 30, connecting bar 31, servo motor 32, and lifting slot 35, the operation of the movable end of electric cylinder 23 can drive the lifting plate 14 and rubber roller 26 to fit against the bottom wall of roller 10. Then, the rotation of rubber roller 26 drives roller 10 to move, making it convenient for workers to remove roller 10. It is easy to use and has a simple structure.
