Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt conveyor belt reversing and turning device. Background Technology

[0002] The shift from the "golden decade" of the coal market has resulted in persistently high coal inventories, a sharp decline in prices, and severe threats to the profitability of mines, while the coal mining machinery manufacturing industry has also been severely impacted. Faced with increasingly fierce market competition, it has become imperative to consider adding new auxiliary methods to reduce the operating costs of coal mines.

[0003] The conveyor belt accounts for one-third of the total cost of a belt conveyor. During use, the receiving surface (dirty surface) of the conveyor belt wears more than the clean surface. To extend the service life of the conveyor belt, coal mine workers often need to rotate the conveyor belt. Using traditional belt-turning devices, it takes three shifts of workers eight hours a day a week to complete the belt rotation. The entire rotation process is time-consuming, arduous, and inefficient. Summary of the Invention

[0004] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a belt reversing and turning device for belt conveyors.

[0005] A belt reversing and turning device for a belt conveyor, comprising:

[0006] The first and second pressing mechanisms have the same structure, but are installed in opposite directions.

[0007] The belt turning mechanism is located between the first belt pressing mechanism and the second belt pressing mechanism. The belt turning mechanism includes a support frame, a left roller, and a right roller. The left roller and the right roller are rotatably mounted on the support frame, and a gap is left between the left roller and the right roller for the conveyor belt to pass through. Support rollers located on both sides of the left roller and the right roller are rotatably mounted on the support frame.

[0008] A clamping mechanism used to hold the conveyor belt during vulcanization.

[0009] Preferably, the centerline of the support roller coincides with the centerline of the distance between the left and right roller bodies.

[0010] Preferably, the left roller and the right roller can move along the horizontal direction of the support frame to adjust the distance between the left roller and the right roller.

[0011] Preferably, the clamping mechanism includes an upper clamping plate and a lower clamping plate arranged opposite each other, and a locking rod; the locking rod passes through the upper clamping plate and the lower clamping plate, the lower end of the locking rod is threaded to the lower clamping plate, and the upper part of the locking rod is rotatably connected to the upper clamping plate. Rotating the locking rod can adjust the distance between the upper clamping plate and the lower clamping plate to realize the clamping or release of the conveyor belt.

[0012] Preferably, a rotating handle is installed at the upper end of the locking rod.

[0013] Preferably, the first pressing mechanism includes a frame, a first pressing roller, and a second pressing roller; the first pressing roller is rotatably disposed on the left side of the frame, the second pressing roller is rotatably disposed on the right side of the frame, and the height of the second pressing roller is higher than the height of the first pressing roller.

[0014] Preferably, the second pressure roller includes an upper roller body and a lower roller body rotatably disposed on the right side of the frame; the upper roller body can move along the longitudinal direction of the frame to adjust the distance between the upper roller body and the lower roller body.

[0015] Preferably, it also includes a vulcanization platform for use when vulcanizing the conveyor belt.

[0016] Compared with existing technologies, the belt reversing and turning device for belt conveyors provided by this utility model, when turning the belt, selects a suitable position to clamp and cut the conveyor belt, reverses it 180°, and then vulcanizes it. After vulcanization, the belt conveyor runs at a low speed using a single drive unit (frequency conversion). After passing through the first belt pressing mechanism, the turning mechanism, and the second belt pressing mechanism, the conveyor belt runs at a belt speed of 2 m / s (main shaft length 1800 meters, closed length 3600 meters) in half an hour, successfully completing the belt reversing and turning. This saves belt changing time and increases the coal conveying time of the conveyor; it is not only safe and reliable but also reduces the labor intensity of workers. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please refer to Figures 1 to 8 This utility model provides a belt reversing and turning device for a belt conveyor, comprising,

[0030] The first pressing mechanism 01 and the second pressing mechanism 02 have the same structure, but the installation directions of the first pressing mechanism 01 and the second pressing mechanism 02 are opposite.

[0031] A belt-turning mechanism 03 is disposed between the first belt-pressing mechanism 01 and the second belt-pressing mechanism 02. The belt-turning mechanism 03 includes a support frame 31, a left roller 32, and a right roller 33. The left roller 32 and the right roller 33 are rotatably mounted on the support frame 31, and a gap is left between the left roller 32 and the right roller 33 for the conveyor belt to pass through. The left roller 32 and the right roller 33 can rotate the conveyor belt 90°. Support rollers 34 are rotatably mounted on the support frame 31 on both sides of the left roller 32 and the right roller 33. When the conveyor belt moves between the left roller 32 and the right roller 33, it will fall downwards due to its own weight. The support rollers 34 support the conveyor belt, which can guide the conveyor belt into the space between the left roller 32 and the right roller 33 and prevent the conveyor belt from scratching and wearing against the support frame 31.

[0032] Clamping mechanism 04 for holding the conveyor belt during vulcanization.

[0033] Of course, in order to ensure that the conveyor belt can accurately enter between the left roller 32 and the right roller 33, the center line of the support roller 34 is consistent with the center line of the distance between the left roller 32 and the right roller 33.

[0034] The left roller 32 and the right roller 33 can move along the horizontal direction of the support frame 31 to adjust the distance between the left roller 32 and the right roller 33.

[0035] To be more specific, the belt clamping mechanism 04 includes an upper clamping plate 41 and a lower clamping plate 42 arranged opposite each other, and a locking rod 43; the locking rod 43 passes through the upper clamping plate 41 and the lower clamping plate 42, the lower end of the locking rod 43 is threaded to the lower clamping plate 42, and the upper part of the locking rod 43 is rotatably connected to the upper clamping plate 41. Rotating the locking rod 43 can adjust the distance between the upper clamping plate 41 and the lower clamping plate 42 to realize the clamping or release of the conveyor belt.

[0036] Two connecting seats 45 are fixed at both ends of the upper clamping plate 41, and the connecting seats 45 have round holes for easy bolt fixing. U-shaped seats 46 are fixed on the upper surfaces of both ends of the lower clamping plate 42. The lower end of the locking rod 43 passes through the U-shaped seat 46 and the lower clamping plate 42, and the lower end of the locking rod 43 is rotatably connected to the lower clamping plate 42, while the locking rod 43 is threadedly connected to the U-shaped seat 46.

[0037] To facilitate rotation of the locking rod 43 during use, a rotating handle 44 is installed at the upper end of the locking rod 43. The rotating handle 44 can be a rod installed radially along the locking rod 43, or it can be a disc fixed to the end of the locking rod 43.

[0038] More specifically, the first pressing mechanism 01 includes a frame 11, a first pressing roller 12, and a second pressing roller 13. The first pressing roller 12 is rotatably disposed on the left side of the frame 11, and the second pressing roller 13 is rotatably disposed on the right side of the frame 11, with the height of the second pressing roller 13 being higher than the height of the first pressing roller 12. The first pressing mechanism 01 and the second pressing mechanism 02 are installed in opposite directions, meaning the first pressing roller 12 on the first pressing mechanism 01 and the first pressing roller 12 on the second pressing mechanism 02 face opposite directions.

[0039] The second pressure roller 13 includes an upper roller body 131 and a lower roller body 132 rotatably disposed on the right side of the frame 11; the upper roller body 131 can move along the longitudinal direction of the frame 11 to adjust the distance between the upper roller body 131 and the lower roller body 132.

[0040] In order to facilitate the vulcanization of the conveyor belt, a vulcanization platform was also set up for use during the vulcanization of the conveyor belt.

[0041] During the reversing and turning of the conveyor belt, a suitable position is first selected to clamp and cut the conveyor belt. Then, the conveyor belt is rotated 180°, and the cut part of the conveyor belt is vulcanized and clamped by the clamping mechanism 04. After vulcanization, the conveyor belt is driven at low speed using a single set of drive devices (frequency conversion). After passing through the first pressing mechanism 01, the turning mechanism 03, and the second pressing mechanism 02, the conveyor belt runs at a belt speed of 2 m / s (main shaft length 1800 meters, closed length 3600 meters) for half an hour, successfully completing the reversing and turning of the conveyor belt. The first pressing mechanism 01 and the second pressing mechanism 02 ensure the compression force of the conveyor belt during the reversing and turning process.

[0042] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
