Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and in particular to a steering mechanism for a suspended belt conveyor system. Background Technology

[0002] An air cushion conveyor is a belt conveyor that uses a thin air film to support the conveyor belt and the material on it. It replaces the idlers of a roller belt conveyor with perforated air chambers. When an air source supplies air with a certain pressure and flow rate into the air chamber, the air escapes through small holes in the disc grooves, forming a pressurized air film between the conveyor belt and the disc grooves, supporting the conveyor belt and the material above it. This transforms the roller support arranged at fixed intervals into a continuous air cushion support, changing the roller friction between the conveyor belt and the idlers into fluid friction between the conveyor belt and the disc grooves using air as the medium, thus reducing running resistance.

[0003] Air chambers are usually made of rigid materials. When the conveyor belt turns, the conveyor belt will also deform slightly. If the air chamber is made to bend directly, it is difficult to achieve smooth material transportation at the turning point because the conveyor belt is blown up during transportation. In the existing technology, most of the transportation is carried out by using multiple conveyors with different heights and connected end to end. When transporting mineral materials, this will cause dust and pollute the environment when the two conveyors exchange items. Therefore, a suspended belt conveyor system turning mechanism is proposed to solve the above problems. Summary of the Invention

The first motor transmits power to the transmission component, which drives the vertical plate to move. The vertical plate is movably connected to the air chamber, and several air chambers are movably connected to each other. When the first motor drives the vertical plate to move, the curvature of the upper surface formed by the combination of several air chambers changes. This can adapt to the conveyor belt transporting items when turning. When the conveyor belt needs to turn, since the conveyor belt is mostly made of rubber, it will deform. At the same time, the transported items should not be thrown off the conveyor belt when turning. Therefore, it is necessary to adjust the curvature of the upper surface formed by the combination of several air chambers. Moving two vertical plates can achieve this effect. When the curvature of the upper surface formed by the combination of several air chambers becomes deeper, the items can be placed in a deeper position and will not be thrown off. It also reduces the wrinkling of the conveyor belt at the turning point. The lifting roller assembly is used to lift the return conveyor belt. The first base plate, the second base plate, and the two support plates form a stable frame structure. The second base plate is movably connected to the mounting plate, which allows the angle of the mounting plate to be adjusted. At turns, the mounting plate is tilted inward to improve the stability of the conveyor belt and prevent items from being thrown off the conveyor belt. The lifting roller assembly can be set to lift the conveyor belt at different angles to adapt to different turning situations. When the turning angle is large, the lifting roller assembly can be raised appropriately, and when the turning angle is small, the lifting roller assembly can be lowered appropriately.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] Reference Figure 1-8 This invention provides a steering mechanism for a suspended belt conveyor system, comprising a plurality of guiding devices arranged at intervals, the guiding devices including:

[0034] The first lifting mechanism includes a mounting plate 1 and a first motor 16 fixedly connected to the mounting plate 1. Two vertical plates 2 are movably connected to the mounting plate 1. The two vertical plates 2 are movably connected to the mounting plate 1 through a transmission assembly. The first motor 16 is connected to the transmission assembly. Several air chambers 3 are movably connected between the two vertical plates 2. The air chambers 3 are movably connected to each other. The air chambers 3 are connected to a fan 4. Several air holes 5 are opened on the top surface of the air chambers 3. The air chambers 3 are located below the conveyor belt 14. A guide roller assembly is provided on the vertical plate 2.

[0035] The second lifting mechanism includes a first base plate 6 and a second base plate 7. Two support plates 8 are fixedly connected between the first base plate 6 and the second base plate 7. A lifting roller assembly is movably connected to the first base plate 6, and the second base plate 7 is movably connected to the mounting plate 1.

[0036] In use, several guide devices can be arranged at intervals, and the number of guide devices can be set according to the required turning conditions, which facilitates adjustment according to usage needs in actual applications. The blower 4 blows air into the air chamber 3, and the gas exits the air chamber 3 through the air hole 5. The gas exiting from the air hole 5 blows the conveyor belt 14 up, forming an air film between the conveyor belt 14 and the air chamber 3, facilitating the conveyor belt 14 to transport items. The first motor 16 transmits power to the transmission component, which drives the vertical plate 2 to move. The vertical plate 2 is movably connected to the air chamber 3, and several air chambers 3 are movably connected to each other. When the first motor 16 drives the vertical plate 2 to move, the curvature of the upper surface formed by the combination of several air chambers 3 changes, thus adapting to the conveying... When the conveyor belt 14 is transporting items at a turning point, it will deform when it needs to turn because it is mostly made of rubber. At the same time, the transported items should not be thrown off the conveyor belt 14 when turning. Therefore, it is necessary to adjust the curvature of the upper surface formed by the combination of several air chambers 3. This effect can be achieved by moving the two vertical plates 2. When the curvature of the upper surface formed by the combination of several air chambers 3 becomes deeper, the items can be placed in a deeper position and will not be thrown off. At the same time, it also reduces the wrinkling of the conveyor belt 14 at the turning point. The lifting roller assembly is used to lift the return conveyor belt 14. The first base plate 6, the second base plate 7, and the two support plates 8 form a stable frame structure to provide support for the device. The second base plate 7 is movably connected to the mounting plate 1, so that the angle of the mounting plate 1 can be adjusted. At the turning point, the mounting plate 1 is tilted inward to improve the stability of the conveyor belt 14 in transporting items and prevent items from being thrown off the conveyor belt 14. The lifting roller assembly can be set to lift the conveyor belt 14 at different angles to adapt to different turning situations. When the turning angle is large, the lifting roller assembly can be raised appropriately, and when the turning angle is small, the lifting roller assembly can be lowered appropriately.

[0037] In a further optimized design, several air chambers 3 are movably connected, and several connecting blocks 9 are fixedly connected to each air chamber 3. Each connecting block 9 has a through hole, and a first rotating shaft 10 passes through the two connecting blocks 9 on two adjacent air chambers 3. The connecting blocks 9 and the first rotating shaft 10 are rotatably connected. A ventilation pipe 11 is fixedly connected to each air chamber 3, and the end of the ventilation pipe 11 away from the air chamber 3 is fixedly connected to the fan 4. The several air chambers 3 are rotatably connected by the connecting blocks 9 and the first rotating shaft 10, making the connection more flexible. The fan 4 provides gas to the air chambers 3 through the ventilation pipe 11 to lift the conveyor belt 14.

[0038] Further optimization of the scheme: the air chamber 3 includes a first arc-shaped sidewall 12 and a second arc-shaped sidewall 13. The first arc-shaped sidewall 12 is provided with several air holes 5. The first arc-shaped sidewall 12 is located below the conveyor belt 14. The external dimensions of the air chambers 3 between the two vertical plates 2 decrease sequentially. The first arc-shaped sidewall 12 is a relatively gentle arc, mainly used to open the air holes 5, which facilitates the lifting of the conveyor belt 14. The second arc-shaped sidewall 13 has a larger arc, which can form an air chamber 3 for storing gas. The external dimensions of the air chambers 3 between the two vertical plates 2 decrease sequentially, so that the shape of the guiding device can be trapezoidal, which is convenient for different turning situations. The smaller the turning angle, the more straight the conveyor belt 14 is, and the fewer guiding devices are used. The larger the turning angle, the larger the turn of the conveyor belt 14, which requires more guiding devices.

[0039] In a further optimized design, the transmission assembly includes a first threaded rod 17, a first motor 16 fixedly connected to the first threaded rod 17, two brackets 18 fixedly connected to the mounting plate 1, the first threaded rod 17 rotatably connected to the brackets 18, a threaded hole on the upright plate 2, the first threaded rod 17 rotatably connected to the threaded hole, a T-slot on the upright plate 2, and two T-blocks 15 fixedly connected to the mounting plate 1, the T-blocks 15 being located within the T-slots and slidably connected to the T-slots; the first motor 16 drives the first threaded rod 17, which in turn moves the upright plate 2; the upright plate 2 and the mounting plate 1 are connected by the T-slots and T-blocks 15, preventing the upright plate 2 from detaching from the mounting plate 1 when it moves; the brackets 18 provide support for the first threaded rod 17; in this embodiment, the surfaces of the T-blocks 15 and the T-slots are smooth, and the surfaces of the parts where the mounting plate 1 and the upright plate 2 contact are also smooth.

[0040] In a further optimized design, an auxiliary component is fixedly connected to the upright plate 2. The auxiliary component includes a reinforcing plate 19, which is fixedly connected to the upright plate 2. The reinforcing plate 19 has a T-shaped groove, which is slidably connected to a T-shaped block 15. A through hole is provided on the reinforcing plate 19, and a first threaded rod 17 passes through the through hole. A groove 20 is provided on the mounting plate 1, and several pulleys 21 are embedded in the groove 20. The upright plate 2 and the reinforcing plate 19 respectively abut against the pulleys 21. The reinforcing plate 19 is used to support the upright plate 2, making the upright plate 2 more stable when the conveyor belt 14 transports items. The reinforcing plate 19 and the T-shaped block 15 are slidably connected through the T-shaped groove. When the upright plate 2 moves, it can drive the reinforcing plate 19 to move. The pulleys 21 can reduce the friction between the upright plate 2, the reinforcing plate 19 and the mounting plate 1, making the sliding of the upright plate 2 and the reinforcing plate 19 more flexible.

[0041] The scheme is further optimized. The guide roller assembly includes several guide rollers 22. The guide rollers 22 are rotatably connected to the vertical plate 2 through the hinge seat 23. The end of the guide roller 22 away from the vertical plate 2 is rotatably connected to the first fixed plate 24. An extension plate 25 is fixedly connected to the vertical plate 2. A first electric telescopic rod 26 is movably connected between the extension plate 25 and the first fixed plate 24. The fixed end of the first electric telescopic rod 26 is rotatably connected to the extension plate 25 through the hinge seat 23. The movable end of the first electric telescopic rod 26 is rotatably connected to the first fixed plate 24 through the hinge seat 23. Several guide rollers 22 are used to assist the conveyor belt 14 in conveying items. At the turning point, if the conveyor belt 14 leaves the air chamber 3, the guide rollers 22 can assist the conveyor belt 14 in sliding to avoid damage when the conveyor belt 14 rubs against other positions. When the first electric telescopic rod 26 extends or retracts, it can drive the guide rollers 22 to rotate, so as to adapt to different turning situations. Several guide rollers 22 are fixedly connected to the first fixed plate 24. When the first electric telescopic rod 26 extends or retracts, it can drive multiple guide rollers 22 to rotate at the same time.

[0042] In a further optimized design, several first connecting plates 27 are fixedly connected to the second base plate 7, and several second connecting plates 28 are fixedly connected to the mounting plate 1. Rotating holes are provided on the first connecting plates 27 and 28, and these holes are concentrically arranged. A second rotating shaft 29 passes through the rotating holes of the first connecting plates 27 and 28, and is rotatably connected to the rotating holes. Several cylinders 44 are rotatably connected to the second base plate 7, and the movable ends of the cylinders 44 are rotatably connected to the mounting plate 1 via hinge seats 23. The first connecting plates 27 and 28 are rotatably connected via the second rotating shaft 29, thus enabling a rotatable connection between the second base plate 7 and the mounting plate 1. In this embodiment, the cylinders 44 are located on both sides of the first connecting plates 27 and 28. When the angle of the mounting plate 1 needs to be adjusted, it can be achieved by extending or retracting the cylinders 44.

[0043] The scheme is further optimized. The lifting roller assembly includes several rotating rollers 30. A middle plate 31 is fixedly connected to the first base plate 6. The two sides of the middle plate 31 are rotatably connected to the rotating rollers 30 through hinge seats 23. The end of the rotating roller 30 away from the middle plate 31 is rotatably connected to a second fixed plate 32 through the hinge seat 23. A second electric telescopic rod 33 is movably connected between the second fixed plate 32 and the first base plate 6. The fixed end of the second electric telescopic rod 33 is rotatably connected to the first base plate 6 through the hinge seat 23, and the movable end of the second electric telescopic rod 33 is rotatably connected to the second fixed plate 32 through the hinge seat 23. The rotating rollers 30 are used to lift the return conveyor belt 14. One end of the rotating roller 30 is rotatably connected to the middle plate 31, and the other end of the rotating roller 30 is rotatably connected to the second fixed plate 32. When the second electric telescopic rod 33 extends or retracts, it can drive the second fixed plate 32 to move. In this way, multiple rotating rollers 30 can be adjusted at the same time. Under different turning conditions, the tilt angle of the rotating rollers 30 can be adjusted to make the conveyor belt 14 run smoothly.

[0044] The method of using this device involves arranging several guiding devices at intervals according to the required turning radius. The larger the turning angle, the more guiding devices are needed to turn the conveyor belt 14. The blower 4 supplies gas to the air chamber 3 through the ventilation pipe 11. The gas discharged from the air hole 5 blows the conveyor belt 14, forming an air film between the conveyor belt 14 and the air chamber 3. This reduces friction between the conveyor belt 14 and the equipment, facilitating the transport of items. When the conveyor belt 14 needs to turn, since it is mostly made of rubber, it will deform. The first motor 16 drives the first threaded rod 17, which, when rotating, moves the vertical plate 2. The vertical plate 2 and the mounting plate 1 are connected by a T-slot and a T-block 15. After the vertical plate 2 moves, it can... The curvature of the upper surface of the several air chambers 3 is adjusted to prevent items on the conveyor belt 14 from being thrown out. Several guide rollers 22 can assist the conveyor belt 14 in sliding to avoid damage when the conveyor belt 14 rubs against other positions. The first connecting plate 27 and the second connecting plate 28 are rotatably connected through the second rotating shaft 29, so that the second base plate 7 and the mounting plate 1 can be rotatably connected. When it is necessary to adjust the angle of the mounting plate 1, the cylinder 44 can be extended or retracted. The rotating roller 30 is used to lift the return conveyor belt 14. Adjusting the tilt angle of the rotating roller 30 can adapt to different turning conditions.

[0045] Example 2

[0046] Reference Figure 9-10The difference between this embodiment and Embodiment 1 is that: a lifting assembly is fixedly connected to any of the upright plates 2. The lifting assembly includes a lifting plate 34 and a second motor 35 that is drivenly connected to the lifting plate 34. The upright plate 2 includes an upper upright plate 36 and a lower upright plate 37. The upper upright plate 36 has a dovetail groove 38. A dovetail block 39 is fixedly connected to the lower upright plate 37. The dovetail block 39 is located in the dovetail groove 38 and is movably connected to the dovetail groove 38. A flat plate 40 is fixedly connected to the lower upright plate 37. The second motor 35 is fixedly connected to the lower upright plate 37. The upper plate 36 is fixedly connected to the flat plate 40, and the lifting plate 34 is fixedly connected to the upper plate 36. Through the cooperation of the dovetail groove 38 and the dovetail block 39, the upper plate 36 and the lower plate 37 are more stable when sliding. The second motor 35 drives the lifting plate 34 to move up and down, thereby driving the upper plate 36 to move up and down. Under different turning radii, when the effect cannot be achieved by the cylinder 44, the height difference between the two sides of several air chambers 3 can be adjusted by adjusting the height of the upper plate 36, so that the conveyor belt 14 can transport items more stably.

[0047] In a further optimized design, a drive gear 41 is fixedly connected to the output end of the second motor 35, and a second threaded rod 42 is rotatably connected to the plate 40. A threaded hole is provided on the lifting plate 34, which is rotatably connected to the second threaded rod 42. A driven gear 43 is fixedly connected to the second threaded rod 42, and the drive gear 41 meshes with the driven gear 43. The second motor 35 drives the drive gear 41 to rotate, which in turn drives the driven gear 43 to rotate. The driven gear 43 then drives the second threaded rod 42 to rotate, thereby causing the second threaded rod 42 to move the lifting plate 34 up and down. The lower end of the second threaded rod 42 is rotatably connected to the plate 40. In this way, the plate 40 bears most of the weight, reducing the power requirement of the second motor 35 and making it easier for the lifting plate 34 to rise or fall.
