Description

Technical Field

[0001] This invention relates to the field of conveyor belt alignment technology, specifically to a double-push-rod hydraulic alignment device. Background Technology

[0002] In industrial equipment, belt conveyor systems are essential tools for material handling. However, due to various reasons, belt conveyors are prone to deviation during operation, which not only affects production efficiency but may also lead to equipment damage and safety accidents.

[0003] Traditional belt alignment methods have limitations. They typically require manual inspection and adjustment of the belt position periodically, which is time-consuming, labor-intensive, and has inconsistent results. While some existing mechanical alignment devices can automatically detect and adjust the belt position, the friction between the belt and the alignment roller is high during the alignment process, leading to severe wear on the bottom of the belt. After long-term use, this results in significant damage to the belt and reduces its service life. Summary of the Invention

[0019] The beneficial effects of this invention are:

[0020] (1) By fixing multiple mounting plates on the conveyor, when the belt on the conveyor deviates, the belt drives the hydraulic transmission control mechanism to run. Then the hydraulic transmission control mechanism starts the electric hydraulic push rod to run. The electric hydraulic push rod drives the mounting frame to rotate, thereby driving the belt to move and tilting the belt to one side. At the same time, the belt is driven to move through the adjusting roller, so that the belt moves to the middle position of the mounting frame, thereby realizing automatic correction of the deviated belt.

[0021] (2) During the belt correction process, the mounting frame is rotated in the opposite direction of the belt offset, so that the material on the belt tilts and the weight of the material on the belt is reduced. Then, the adjusting roller is rotated and the adjusting roller and the belt roll and rub against each other, so that the belt is moved. This reduces the friction force and wear of the belt during the correction process, thereby reducing the damage to the belt and improving the service life of the belt.

[0022] (3) During operation, the belt driven by the conveyor drives the adjusting pipe and guide roller to rotate, thereby driving the first mounting pipe and the second mounting pipe to rotate. The first mounting pipe and the second mounting pipe drive the cleaning roller and cleaning brush on the cleaning mechanism to rotate, so that the dirt at the bottom of the belt can be cleaned in a timely and sufficient manner, preventing the dirt adhering to the belt from sticking to the conveyor roller and causing the belt to deviate during the conveying process, thus improving the stability of belt conveying.

[0038] 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.

[0041] By installing multiple belt alignment devices on the belt conveyor, that is, by fixing multiple mounting plates 1 on the belt conveyor, the belt is attached to the two adjusting pipes 4 and the guide rollers 6 inside the mounting frame 2. When the conveyor is running and the belt deviates, the belt alignment device will automatically and promptly correct the belt deviation. At the same time, the belt alignment device reduces wear on the belt and improves the belt's service life during the correction process. When the belt drives the adjusting pipes 4 and the guide rollers 6 to rotate, it drives the first mounting pipe 3 and the second mounting pipe 5 to rotate.

The belt cleaning mechanism promptly cleans the dirt at the bottom of the belt, preventing the dirt adhering to the belt from sticking to the conveyor rollers and causing the belt to deviate during the conveying process, thus improving the stability of the belt conveyor.

A first spring 16, fixedly connected to the connecting plate 14, is fixedly sleeved on the outer surface of the first telescopic rod 15. Multiple mounting frames 17 are fixedly connected to the connecting plate 14. A mounting shaft 18 is rotatably connected inside each mounting frame 17. Two adjusting rollers 19 are fixedly sleeved on the outer surface of the mounting shaft 18. The outer surface of the adjusting rollers 19 is fixedly... Multiple friction blocks are connected, and multiple adjustment grooves 190 are opened on the outer surface of the adjustment tube 4. A hydraulic transmission control mechanism connected to both the mounting frame 2 and the first mounting tube 3 is connected to one side of the transmission plate 11. The hydraulic transmission control mechanism is used to drive the transmission plate 11 to move. An adjustment drive mechanism connected to the mounting frame 2 is connected to the outer surface of the mounting shaft 18. The adjustment drive mechanism is used to drive the mounting shaft 18 to rotate. The adjustment drive mechanism is connected to the hydraulic transmission control mechanism. Two electric hydraulic push rods 191 are rotatably connected to the top of the mounting plate 1. The top of the electric hydraulic push rods 191 is rotatably connected to the bottom of the mounting frame 2. The electric hydraulic push rods 191 are connected to the hydraulic transmission control mechanism.

[0044] The hydraulic transmission control mechanism includes a support plate 21 fixedly connected to the mounting bracket 2. A second telescopic rod 22 is fixedly connected to one side of the support plate 21. A support frame 23 is fixedly connected to one end of the second telescopic rod 22. A buffer spring 298 fixedly sleeved on the outer surface of the second telescopic rod 22 and fixedly connected to the support frame 23 is fixedly fitted. A transmission roller 24 is rotatably connected inside the support frame 23. One end of the transmission roller 24 is fixedly connected to the transmission shaft of the oil pump 25 via a coupling. An oil storage tank 26 fixedly connected to the mounting bracket 2 is fixedly connected to the input end of the oil pump 25 via a pipe. A first connecting pipe 27 is fixedly connected to the output end of the oil pump 25. A second connecting pipe 28 is fixedly connected to the outer surface of the first connecting pipe 27. A third connecting pipe 29 rotatably connected to the first mounting pipe 3 is fixedly connected to one end of the second connecting pipe 28 via a pipe. A first hydraulic oil tank 290 fixedly connected to the adjusting pipe 4 is fixedly connected to one end of the first mounting pipe 3 via a pipe. A first push plate 291 is slidably connected inside the first hydraulic oil tank 290. A third spring 292, which is fixedly connected to the first hydraulic oil tank 290, is fixedly connected to one side of the first push plate 291. A first transmission column 293, which is slidably connected to the first hydraulic oil tank 290, is fixedly connected to the other side of the first push plate 291. A first transmission disc 294, which is fixedly connected to the transmission plate 11, is fixedly connected to one side of the first transmission column 293. A third telescopic rod 295 is fixedly connected to the support frame 23. A trigger delay switch 296 is fixedly connected to one end of the third telescopic rod 295. A fifth spring 297, which is connected to the support frame 23, is fixedly sleeved on the outer surface of the third telescopic rod 295. The trigger delay switch 296 is connected to the electric hydraulic push rod 191 and the adjustment drive mechanism. A return oil pipe 31, which is fixedly connected to the oil storage tank 26, is fixedly connected to the outer surface of the first connecting pipe 27. An electromagnetic valve 32 is installed on the return oil pipe 31.

[0045] The adjustment drive mechanism includes a transmission rack 41 slidably connected to the transmission plate 11. One side of the transmission rack 41 is meshed with a one-way gear 42 fixedly sleeved to the mounting shaft 18. A second hydraulic oil tank 43 is fixedly connected inside the adjustment pipe 4. A second push plate 44 is slidably connected inside the second hydraulic oil tank 43. A fourth spring 45, which is fixedly connected to the second hydraulic oil tank 43, is fixedly connected to one side of the second push plate 44. A second transmission column 46 is fixedly connected to the other side of the second push plate 44. A second transmission disc 47 is fixedly connected to one side of the second transmission column 46. One side of the second transmission disc 47 is connected to the transmission rack 41 via a connecting column. Next, the second hydraulic oil tank 43 is connected to the first mounting pipe 3 through a pipe. The first mounting pipe 3 is connected to a drive mechanism connected to the mounting frame 2. The drive mechanism is connected to the trigger delay switch 296. The drive mechanism includes a drive box 51 fixedly connected to the mounting frame 2. An electric hydraulic rod 52 is fixedly connected inside the drive box 51. One end of the electric hydraulic rod 52 is fixedly connected to a third push plate 53 fixedly connected to the drive box 51. The electric hydraulic rod 52 is connected to the trigger delay switch 296. A fourth connecting pipe 54 rotatably connected to the first mounting pipe 3 is fixedly connected to one side of the drive box 51 through a pipe.

[0046] When the belt deviates, it contacts the transmission roller 24 inside the support frame 23, causing the transmission roller 24 to rotate. The transmission roller 24 drives the oil pump 25 to rotate, and the oil pump 25 pumps oil from the oil reservoir 26 into the second connecting pipe 28 through the first connecting pipe 27. Subsequently, the second connecting pipe 28 passes the oil into the first hydraulic oil tank 290 through the third connecting pipe 29. This pushes the first push plate 291 inside the first hydraulic oil tank 290 to move, which in turn moves the first transmission column 293. The first transmission column 293 then moves the first transmission disc 294. 4. The transmission plate 11 is moved. After the correction is completed, the belt no longer contacts the transmission roller 24. At this time, the oil pump 25 stops working. Then, the solenoid valve 32 on the return oil pipe 31 is opened. Then, the first push plate 291 moves under the force of the third spring 292, returning the oil to the oil storage tank 26 through the return oil pipe 31. Then, the solenoid valve 32 closes. At the same time, the belt drives the transmission roller 24 to rotate, triggering the trigger delay switch 296 on the support frame 23. At this time, the trigger delay switch 296 starts to start, and the electric hydraulic rod 52 is opened to work. At the same time, the electric hydraulic rod 52 drives the drive box 51. The third push plate 53 reciprocates, and the third push plate 53 introduces oil from the drive box 51 into the first mounting pipe 3 through the fourth connecting pipe 54. Then, the first mounting pipe 3 introduces oil into the second hydraulic oil tank 43 through a pipeline. When the third push plate 53 moves downwards, it fills the second hydraulic oil tank 43 with oil, causing the second push plate 44 and the second transmission column 46 to move outwards. When it moves upwards, it draws oil into the second hydraulic oil tank 43, causing the second push plate 44 and the second transmission column 46 to move inwards. Simultaneously, the second push plate 44 in the second hydraulic oil tank 43, in conjunction with the fourth spring 45, drives the second push plate 44 to move inwards. The second hydraulic oil tank 43 reciprocates, the second push plate 44 drives the second transmission column 46 and the second transmission disc 47 to reciprocate, the second transmission disc 47 drives the transmission rack 41 to reciprocate, and the transmission rack 41 drives the one-way gear 42 to rotate. (The one-way gear 42 can only drive the mounting shaft 18 to rotate when it rotates in the forward direction. It does not drive the mounting shaft 18 to rotate when it rotates in the reverse direction. For example, the one-way gear 42 design on the rear wheel axle of a bicycle is existing technology and will not be described in detail here.) This enables the mounting shaft 18 and the adjusting roller 19 to rotate toward the center position of the mounting frame 2.

[0047] When the belt deviates, the deviated belt drives the hydraulic transmission control mechanism. The hydraulic transmission control mechanism then moves the electro-hydraulic push rod 191, causing it to rotate the mounting bracket 2 on that side upwards. Simultaneously, the belt moves upwards, tilting the material on the belt to one side and reducing the weight load on that side. At the same time, the hydraulic transmission control mechanism moves the transmission plate 11, which in turn moves the first transmission block 12. The first transmission block 12 pushes the second transmission block 13 upwards. The second transmission block 13 moves the connecting plate 14 and the mounting frame 17 on the connecting plate 14 towards the outside of the adjusting groove 190 on the adjusting tube 4, causing the adjusting roller 19 to contact the bottom of the belt. The belt continues to move, simultaneously rotating the adjusting tube 4. Simultaneously, the hydraulic transmission control mechanism drives the adjusting drive mechanism, which... The mounting shaft 18 rotates unidirectionally towards the center of the mounting frame 2. The mounting shaft 18 drives the adjusting roller 19 to rotate. At this time, the adjusting roller 19 rubs against the bottom of the belt, causing the belt to move towards the center of the mounting frame 2. Simultaneously, the material on the belt is driven by the electro-hydraulic push rod 191 to rotate the mounting frame 2 to the other side, causing a portion of the material to move to the center position. This reduces the pressure on the belt on that side, reduces the friction between the belt and the adjusting roller 19, facilitates the movement of the belt to the center position, and reduces damage to the bottom of the belt. During the movement, the belt rolls and rubs against the adjusting roller 19 on the adjusting tube 4, resulting in less friction and wear during belt correction, thus reducing damage to the belt. This achieves automatic correction of belt misalignment, while minimizing belt loss during correction and improving belt lifespan.

[0048] Implementation Three

[0049] Based on Example 2, please refer to Figure 1 and Figure 10 As shown, the belt cleaning mechanism includes a first gear 61 that is fixedly sleeved with both the first mounting tube 3 and the second mounting tube 5. A second gear 62 is meshed with the outer surface of the first gear 61. A first rotating shaft 63 that is rotatably connected to the mounting frame 2 is fixedly sleeved in the middle of the second gear 62. A second rotating shaft 64 that is connected to the mounting frame 2 is driven by a transmission wheel and a transmission belt on the outer surface of the first rotating shaft 63. A cleaning roller 65 is fixedly connected to one end of the second rotating shaft 64. A plurality of cleaning brushes 66 are fixedly connected to the cleaning roller 65.

[0050] The belt moves along the adjusting pipe 4 and guide roller 6, causing the adjusting pipe 4 and guide roller 6 to rotate. The adjusting pipe 4 and guide roller 6 drive the first mounting pipe 3 and the second mounting pipe 5 to rotate. The first mounting pipe 3 and the second mounting pipe 5 drive the first gear 61 to rotate. Since the first gear 61 is designed to be larger than the second gear 62, the first gear 61 drives the second gear 62 to rotate rapidly. The second gear 62 drives the first rotating shaft 63 to rotate. The first rotating shaft 63 drives the second rotating shaft 64 to rotate through the transmission wheel and transmission belt. The second rotating shaft 64 drives the cleaning roller 65 and the cleaning brush 66 to rotate. The cleaning brush 66 cleans the dust at the bottom of the belt, thereby automatically cleaning the dirt adhering to the bottom of the belt. This reduces the contact between the dirt at the bottom of the belt and the conveyor roller, which could cause the conveying force to shift and the belt to deviate. This reduces the occurrence rate of belt deviance and improves the stability of the conveyor.

[0051] The working principle of this invention is as follows: By installing multiple correction devices on the belt conveyor, that is, by fixing multiple mounting plates 1 on the belt conveyor, the belt is attached to the two adjusting pipes 4 and the guide rollers 6 inside the mounting frame 2. When the conveyor is running and the belt deviates, the correction devices automatically correct the belt in a timely manner. At the same time, the correction devices reduce wear on the belt and improve the service life of the belt during the correction process. Meanwhile, when the belt drives the adjusting pipes 4 and the guide rollers 6 to rotate, it drives the first mounting pipe 3 and the second mounting pipe 5 to rotate. The first mounting pipe 3 and the second mounting pipe 5 drive the belt cleaning mechanism to rotate. The belt cleaning mechanism cleans the dirt at the bottom of the belt in a timely manner, preventing the dirt adhering to the belt from sticking to the conveyor rollers and causing the belt to deviate during the conveying process, thereby improving the stability of the belt conveyor.

[0052] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
