Description

Technical Field

[0001] This invention relates to the field of load-bearing idler assembly technology, and in particular to an anti-deflection load-bearing idler assembly. Background Technology

[0002] In the actual operation of belt conveyors, belt misalignment is a long-standing and critical technical problem affecting system stability. Misalignment not only leads to material spillage and belt edge wear, but also causes equipment vibration and noise, and in severe cases, may even cause safety accidents. To correct belt misalignment, the industry commonly uses self-aligning idler sets as the main correction device.

[0003] A search revealed Chinese patent CN119190721B, which discloses an anti-deflection load-bearing idler assembly, comprising: a base, a flat roller rotatably connected to the center of the base, and side rollers symmetrically arranged at both ends of the flat roller, with the side rollers forming an angle with the flat roller; an adjustment mechanism, including an adjustment plate and a support wheel connected to the adjustment plate, a lifting rod on the base, and a connecting plate on the lifting end of the lifting rod, the connecting plate being connected to the adjustment plate via a telescopic component, the telescopic component being used to adjust the distance between the adjustment plate and adjacent flat rollers or side rollers, a pressure sensor communicatively connected to the telescopic component on the adjustment plate, the detection end of the pressure sensor being connected to the support wheel, the support wheel being used for rolling contact with adjacent flat rollers or side rollers; and a connecting component, disposed on the adjustment plate, the adjustment plate rotating relative to the lifting rod via the connecting component to make the support wheel parallel to the flat rollers or side rollers.

[0004] Based on the above research and existing technology, it was found that in the actual correction process of existing self-aligning idler sets, when the belt deviates, the load pressure is no longer evenly distributed across the entire idler frame, but concentrated on one side of the belt deviation. This uneven stress causes the idler frame to bear additional overturning moments and torsional stresses, which can easily lead to structural deformation or loosening of connecting parts over a long period of time, severely weakening the rigidity and stability of the support. Secondly, when faced with severe belt deviation or when the conveyor is carrying a large volume of high-load materials, the self-aligning idler set's own correction action may cause instability. Under the action of a large lateral force, the idler set not only fails to effectively correct the deviation, but its rotating frame or hinge mechanism may also unexpectedly deflect or oscillate excessively, losing its reliable constraint and guiding function for the belt. This instability not only fails to correct the deviation, but also induces and aggravates abnormal vibration, impact, and dynamic wear of the entire conveying system. Summary of the Invention

[0008] Preferably, the clamping unit includes two fixed rails fixedly connected to the roller frame, two sliding frames slidably connected to each of the two fixed rails, a bidirectional threaded rod rotatably connected to each of the two fixed rails, two sliding frames screwed onto the bidirectional threaded rods, an arc-shaped clamping plate fixedly connected to the top of each of the four sliding frames, a gear fixedly connected to one end of each of the two bidirectional threaded rods, a rack meshing with each of the two gears, a fixed sleeve fixedly connected to the bottom end of each of the two racks, a movable rod slidably connected to each of the two fixed sleeves, a vertical rod fixedly connected to each of the two movable rods, a ball rotatably connected to the bottom end of each of the two vertical rods, and a spring piece fixedly connected to both the movable rod and the fixed sleeve.

[0009] Preferably, each of the two fixed tracks is fixedly connected to a telescopic rod, and the bottom end of each of the two telescopic rods is fixedly connected to a fixing block. The two fixing blocks are respectively fixedly connected to two racks, and each of the two telescopic rods is fitted with a connecting spring. The two ends of the connecting spring are respectively fixedly connected to the telescopic rod and the fixing block.

[0010] Preferably, each of the four arc-shaped clamps is rotatably connected to multiple rotating rollers.

[0011] Preferably, the telescopic unit includes two brackets fixedly connected to the roller frame, each bracket having a movable frame slidably connected to it, each movable frame having a stop bar fixedly connected to its top, and each movable frame having an L-shaped rod fixedly connected to its bottom, with the two L-shaped rods respectively contacting two vertical rods.

[0012] Preferably, both of the brackets are provided with telescopic springs, and the two ends of the telescopic springs are fixedly connected to the bracket and the movable frame, respectively.

[0013] Preferably, the rotating unit includes two L-shaped frames fixedly connected to a fixed frame, each L-shaped frame having a rotating shaft rotatably connected to it, one end of each rotating shaft having a rotating wheel fixedly connected to it, each rotating wheel having multiple rotating blocks rotatably connected to it, each rotating block having a spring piece two fixedly connected to it, and the other end of each spring piece two being fixedly connected to the rotating wheel.

[0014] Preferably, the rotating rod and the two rotating shafts are all fixedly connected to transmission wheels, and a transmission belt is tensioned and sleeved on all three transmission wheels.

[0015] This invention provides an improved anti-deflection load-bearing idler assembly, which has the following improvements and advantages compared with the prior art: Firstly, this invention, through the setting of the support unit, allows the belt on the idler roller to deviate when it does. The deviated belt, through traction, drives the idler roller and idler frame to rotate automatically around the rotation axis. The rotation of the idler frame corrects the deviated belt. The rotation of the idler frame drives the rotation axis to rotate, which in turn drives the main bevel gear to rotate. The main bevel gear then drives the secondary bevel gear and the rotating rod to rotate. The rotating rod then drives the notched ring to rotate, which in turn drives the T-shaped piston rod to move downward. The movement of the T-shaped piston rod forces the oil in the fixed cylinder into the U-shaped tube, causing the oil to drive the sliding rod to move upward. The movement of the sliding rod then drives the fixed rod, sliding column, and arc-shaped rail to move upward until the arc-shaped rail contacts the roller. This allows the arc-shaped rail to support the roller, thereby improving the stability of the idler roller frame.

[0016] Secondly, through the clamping unit, when the arc-shaped rail moves upward and contacts the vertical rod, the arc-shaped rail drives the vertical rod to move upward. The movement of the vertical rod drives the movable rod and the fixed sleeve to move. The movement of the fixed sleeve drives the rack to move. The movement of the rack drives the gear and the double-threaded rod to rotate. The rotation of the double-threaded rod drives the two sliding frames to move closer to each other. The two sliding frames moving closer to each other drive the arc-shaped clamping plates to move closer to each other. The two arc-shaped clamping plates moving closer to each other can limit the position of the idler roller, thereby improving the stability of the idler roller.

[0017] Thirdly, when the belt on the idler roller deviates, the belt drives the stop bar to move, the stop bar moves the movable frame to move, the movable frame moves the telescopic spring to compress and elastically deform, the movable frame moves the L-shaped rod to move away from the vertical rod. Since the spring plate is in a compressed state, the spring plate moves the movable rod and the vertical rod to reset, so that the vertical rod moves to directly above the arc-shaped rail. When the arc-shaped rail moves upward, it can drive the vertical rod to move, thereby limiting the idler roller with the arc-shaped clamp. This realizes automatic limiting of the idler roller with belt deviation, improving the stability of the idler roller.

[0018] Fourthly, this invention, through the setting of the rotating unit, the rotating rod rotates, which drives the rotating shaft and rotating wheel to rotate through the transmission belt and three transmission wheels. The rotation of the rotating wheel drives the rotating block to rotate, so that the rotating block on the rotating wheel on the deviated side can push the belt to reset. When the rotating block on the other side rotates and contacts the belt, the belt drives the rotating block to rotate. The rotation of the rotating block causes the spring sheet to compress and undergo elastic deformation, thereby assisting in adjusting the belt to reset. Attached Figure Description

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0023] This invention provides an improved anti-deflection load-bearing idler assembly. The technical solution of this invention is as follows: like Figures 1 to 9 As shown, this embodiment of the invention provides an anti-deflection load-bearing idler assembly, including a fixed frame 1, a rotating shaft 11 rotatably connected to the fixed frame 1, an idler frame 12 fixedly connected to the rotating shaft 11, and a set of idlers 13 fixedly connected to the idler frame 12, and further including: The support mechanism is located on the fixed frame 1; The support mechanism includes a support unit, a clamping unit, a telescopic unit, and a rotating unit. The support unit includes a fixed shell 2 fixedly connected to the fixed frame 1, and the fixed shell 2 rotatably connected to the bottom of the roller frame 12. A rotating rod 21 is rotatably connected to the fixed shell 2, and a secondary bevel gear 22 is fixedly connected to one end of the rotating rod 21. A main bevel gear 23 is fixedly connected to the rotating shaft 11, and the main bevel gear 23 and the secondary bevel gear 22 mesh with each other. A notched ring 24 is fixedly connected to the rotating rod 21, and a fixed cylinder 25 is fixedly connected to the fixed frame 1. A T-shaped piston rod 26 is slidably connected to the fixed cylinder 25, and the T-shaped piston rod 26 contacts the notched ring 24. A U-shaped tube 28 is fixedly connected to the bottom of the fixed cylinder 25, and a sliding rod 29 is slidably connected to the U-shaped tube 28. A fixed rod 210 is fixedly connected to the top of the sliding rod 29, and sliding columns 211 are fixedly connected to both ends of the fixed rod 210. Both sliding columns 211 are slidably connected to the fixed frame 1, and arc-shaped rails 212 are fixedly connected to the top of both sliding columns 211. The bottom of the roller frame 12 is fixedly connected to... Two rollers 14 are positioned directly above two arc-shaped rails 212. Through the support unit, when the belt on the idler roller 13 deviates, the deviated belt, through traction, drives the idler roller 13 and the idler roller frame 12 to rotate automatically around the rotating shaft 11. The rotation of the idler roller frame 12 corrects the deviated belt. The rotation of the idler roller frame 12 drives the rotating shaft 11 to rotate, which in turn drives the main bevel gear 23 to rotate. The main bevel gear 23 then drives the secondary bevel gear 22 and the rotating rod 21 to... The rotating rod 21 rotates, causing the notched ring 24 to rotate. The notched ring 24 rotates, causing the T-shaped piston rod 26 to move downward. The movement of the T-shaped piston rod 26 forces the oil in the fixed cylinder 25 into the U-shaped tube 28, causing the oil to drive the sliding rod 29 to move upward. The movement of the sliding rod 29 causes the fixed rod 210, the sliding column 211, and the arc-shaped rail 212 to move upward until the arc-shaped rail 212 contacts the roller 14, thereby supporting the roller 14 and improving the stability of the roller frame 12.

[0024] Furthermore, a return spring 27 is sleeved on the T-shaped piston rod 26, and the two ends of the return spring 27 are fixedly connected to the T-shaped piston rod 26 and the fixed cylinder 25 respectively. With the setting of the return spring 27, when the roller frame 12 and the rotating shaft 11 are reset, the return spring 27 is reset, which drives the T-shaped piston rod 26 to reset. The T-shaped piston rod 26 pushes the oil in the U-shaped tube 28 back into the fixed cylinder 25, thereby causing the fixed rod 210, the sliding column 211 and the arc-shaped rail 212 to reset.

[0025] Furthermore, the clamping unit includes two fixed rails 3 fixedly connected to the roller frame 12. Two sliding frames 32 are slidably connected to each of the two fixed rails 3. Two bidirectional threaded rods 31 are rotatably connected to each of the two fixed rails 3. The two sliding frames 32 are screwed onto the bidirectional threaded rods 31. Arc-shaped clamping plates 33 are fixedly connected to the tops of the four sliding frames 32. Gears 35 are fixedly connected to one end of each of the two bidirectional threaded rods 31. Racks 36 mesh with each of the two gears 35. Fixed sleeves 37 are fixedly connected to the bottom ends of each of the two racks 36. Movable rods 38 are slidably connected to each of the two fixed sleeves 37. Vertical rods 39 are fixedly connected to the bottom ends of each of the two movable rods 38. A ball bearing is connected to the movable rod 38 and the fixed sleeve 37, and a spring piece 313 is fixedly connected to both. With the clamping unit, when the arc-shaped rail 212 moves upward and contacts the vertical rod 39, the arc-shaped rail 212 drives the vertical rod 39 to move upward. The movement of the vertical rod 39 drives the movable rod 38 and the fixed sleeve 37 to move. The movement of the fixed sleeve 37 drives the rack 36 to move. The movement of the rack 36 drives the gear 35 and the double-threaded rod 31 to rotate. The rotation of the double-threaded rod 31 drives the two sliding frames 32 to move closer to each other. The two sliding frames 32 moving closer to each other drive the arc-shaped clamping plates 33 to move closer to each other. The two arc-shaped clamping plates 33 moving closer to each other can limit the movement of the idler roller 13, thereby improving the stability of the idler roller 13.

[0026] Furthermore, telescopic rods 311 are fixedly connected to both fixed rails 3, and fixed blocks 310 are fixedly connected to the bottom ends of both telescopic rods 311. The two fixed blocks 310 are fixedly connected to the two racks 36 respectively. Connecting springs 312 are sleeved on both telescopic rods 311, and the two ends of the connecting springs 312 are fixedly connected to the telescopic rods 311 and the fixed blocks 310 respectively. With the setting of the telescopic rods 311, the racks 36 move upward, causing the fixed blocks 310 to move. The movement of the fixed blocks 310 causes the telescopic rods 311 to retract. The retraction of the telescopic rods 311 causes the connecting springs 312 to compress and undergo elastic deformation. When the arc-shaped rail 212 returns to its original position, the connecting springs 312 can drive the racks 36 to return to their original position.

[0027] Furthermore, multiple rotating rollers 34 are rotatably connected to each of the four arc-shaped clamps 33; through the setting of the rotating rollers 34, the rotating rollers 34 can rotate, thus not affecting the rotation of the idler roller 13.

[0028] Furthermore, the telescopic unit includes two brackets 4 fixedly connected to the idler roller frame 12. Each bracket 4 has a movable frame 41 slidably connected to it. A stop bar 42 is fixedly connected to the top of each movable frame 41, and an L-shaped rod 43 is fixedly connected to the bottom of each movable frame 41. The two L-shaped rods 43 are in contact with two vertical rods 39 respectively. Each bracket 4 contains a telescopic spring 44, with both ends of the spring fixedly connected to the bracket 4 and the movable frame 41 respectively. Due to the telescopic spring 44, when the belt on the idler roller 13 shifts, the belt drives the stop bar 42 to move, and the movement of the stop bar 42 drives... The movable frame 41 moves, causing the telescopic spring 44 to compress and undergo elastic deformation. The movement of the movable frame 41 also causes the L-shaped rod 43 to move away from the vertical rod 39. Since the spring piece 313 is in a compressed state, it causes the movable rod 38 and the vertical rod 39 to reset, allowing the vertical rod 39 to move directly above the arc-shaped rail 212. When the arc-shaped rail 212 moves upward, it can drive the vertical rod 39 to move, thereby limiting the idler roller 13 with the arc-shaped clamp 33. This achieves automatic limiting of the idler roller with belt offset position, improving the stability of the idler roller.

[0029] Furthermore, the rotating unit includes two L-shaped frames 5 fixedly connected to the fixed frame 1. A rotating shaft 51 is rotatably connected to each of the two L-shaped frames 5. A rotating wheel 52 is fixedly connected to one end of each of the two rotating shafts 51. Multiple rotating blocks 53 are rotatably connected to each of the two rotating wheels 52. Spring pieces 54 are fixedly connected to each of the multiple rotating blocks 53. The other ends of the multiple spring pieces 54 are fixedly connected to the rotating wheels 52. A transmission wheel 55 is fixedly connected to the rotating rod 21 and the two rotating shafts 51. A transmission gear is tensioned and sleeved on all three transmission wheels 55. With the rotation unit in place, the rotating rod 21 rotates, driving the rotating shaft 51 and the rotating wheel 52 to rotate via the transmission belt 56 and three transmission wheels 55. The rotating wheel 52 rotates, causing the rotating block 53 to rotate. This allows the rotating block 53 on the rotating wheel 52 on the side of the deviation to rotate and push the belt to reset. When the rotating block 53 on the other side rotates and contacts the belt, the belt drives the rotating block 53 to rotate. The rotation of the rotating block 53 causes the spring piece 2 54 to compress and undergo elastic deformation, thereby assisting in adjusting the belt to reset.

[0030] Specific implementation steps: When the belt on the idler roller 13 deviates, the belt drives the stop bar 42 to move, the stop bar 42 moves the movable frame 41 to move, the movable frame 41 moves the telescopic spring 44 to compress and elastically deform, the movable frame 41 moves the L-shaped rod 43 to move away from the vertical rod 39, and since the spring piece 313 is in a compressed state, the spring piece 313 drives the movable rod 38 and the vertical rod 39 to reset, so that the vertical rod 39 moves directly above the arc-shaped rail 212. The deflected belt drives the idler roller 13 and the idler roller frame 12 to rotate automatically around the rotating shaft 11 through traction force. The rotation of the idler roller frame 12 can... The misaligned belt is corrected by rotating the idler frame 12, which in turn rotates the rotating shaft 11. The rotating shaft 11 then rotates the main bevel gear 23, which in turn rotates the secondary bevel gear 22 and the rotating rod 21. The rotating rod 21 rotates the notched ring 24, which in turn moves the T-shaped piston rod 26 downwards. This movement of the T-shaped piston rod 26 forces the oil in the fixed cylinder 25 into the U-shaped tube 28, causing the oil to move the sliding rod 29 upwards. The sliding rod 29 then moves the fixed rod 210, the sliding column 211, and the arc-shaped rail 212 upwards until the arc-shaped rail 212 contacts the roller 14, thus causing the arc-shaped rail 212 to contact the roller. 14 provides support, thereby improving the stability of the roller frame 12. When the arc-shaped rail 212 moves upward and contacts the vertical rod 39, the arc-shaped rail 212 drives the vertical rod 39 to move upward. The movement of the vertical rod 39 drives the movable rod 38 and the fixed sleeve 37 to move. The movement of the fixed sleeve 37 drives the rack 36 to move. The movement of the rack 36 drives the fixed block 310 to move. The movement of the fixed block 310 drives the telescopic rod 311 to retract. The retraction of the telescopic rod 311 causes the connecting spring 312 to compress and undergo elastic deformation. The movement of the rack 36 drives the gear 35 and the double-threaded rod 31 to rotate. The rotation of the double-threaded rod 31 causes the two sliding frames 32 to move closer to each other. When the frames 32 move closer together, the arc-shaped clamps 33 move closer together. The two arc-shaped clamps 33 can limit the movement of the idler roller 13, thereby improving the stability of the idler roller 13. The rotation of the rotating rod 21 drives the rotating shaft 51 and the rotating wheel 52 to rotate through the transmission belt 56 and three transmission wheels 55. The rotation of the rotating wheel 52 drives the rotating block 53 to rotate. The rotation of the rotating block 53 on the rotating wheel 52 on the side of the deviation can push the belt to reset. When the rotating block 53 on the other side rotates and contacts the belt, the belt drives the rotating block 53 to rotate. The rotation of the rotating block 53 causes the spring piece 2 54 to compress and undergo elastic deformation, thereby assisting in adjusting the belt to reset.
