Description

Technical Field

[0001] The present invention relates to the technical field of rollers, and in particular to an anti-skid roller for a vehicle-mounted conveyor. Background Art

[0002] In industrial production, belt conveyors are critical material transport equipment, and their operational stability and reliability are crucial. As a core component of belt conveyors, the roller plays a crucial role in driving and supporting the conveyor belt. However, in actual operating conditions, slippage between the conveyor belt and the roller is common due to factors such as material weight fluctuations, ambient humidity, and belt aging. To address this issue, the industry generally adopts methods such as increasing the roller surface roughness or installing integrated anti-slip rubber pads to enhance anti-slip performance.

[0003] Simply increasing the surface roughness: although it is effective initially, it will lead to increased wear on the surface of the conveyed material; more importantly, the roughness will be reduced due to long-term wear, and the anti-slip effect will be significantly attenuated. If an integrated anti-slip rubber pad is used: although it can improve the anti-slip performance, it faces the problems of local wear and high overall replacement costs: for example, during the conveying process, materials are often concentrated in a specific area of ​​the drum (for example, ore is piled on one side when transporting ore), causing the pressure and friction in this area to be much greater than other areas. Long-term local overload operation can easily cause serious local wear of the anti-slip rubber pad in this area. The disadvantage of the existing maintenance method is that once local wear occurs, the current practice is often to replace the entire anti-slip rubber pad, which not only has high maintenance costs, but also cannot perform local repairs or adjustments based on the actual, non-uniform wear conditions, resulting in unnecessary waste and economic burden.

[0030] The following will be combined with the accompanying drawings to clearly and completely describe the technology of the embodiment of the present invention, a non-slip roller for a vehicle-mounted conveyor. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1-9The present embodiment provides an anti-skid roller for a vehicle-mounted conveyor, comprising a roller body 1 and a main shaft 3 that passes through the roller body 1. A reinforcing plate 2 is fixedly connected to the middle part of the interior of the roller body 1. The middle part of the reinforcing plate 2 is passed through by the main shaft 3. The main shaft 3 is the core rotating shaft that passes through the entire roller body 1. Its two ends extend out of the outside of the roller body 1 and can be used to connect a driving device (such as a motor) and an externally supported bearing seat. The main shaft 3 is located on both sides of the interior of the roller body 1 and is respectively sleeved with an adjusting cylinder 4. Blocking plates 5 are installed at both ends of the roller body 1 through a first bolt. An array of card slots 6 are provided on the outer circumferential surface of the roller body 1. An anti-slip belt 8 is provided in the groove 6. The anti-slip belt 8 is made of wear-resistant rubber and has anti-slip grooves on the surface. The two ends of the anti-slip belt 8 extend into the interior of the drum body 1. The drum body 1 is also provided with a rotating assembly 7 and a winding piece 9. The two ends of the anti-slip belt 8 are slidably connected to the winding piece 9. The outer circumferential surface of the drum body 1 is uniformly arrayed with multiple locking grooves 6. These locking grooves 6 are arranged at intervals along the circumference of the drum to accommodate the segmented anti-slip belt 8 and position it to prevent the anti-slip belt 8 from sliding left and right when the drum body 1 rotates. The width and number of the anti-slip belt 8 match the arrangement of the locking grooves 6 on the circumference of the drum. The anti-slip belt 8 and the locking groove 6 are detachable, which facilitates the replacement of the anti-slip belt 8.

[0032] Positioning holes 10 are provided on the end faces of both ends of the reinforcing plate 2 and one side surface of the positioning plate 702. The reinforcing plate 2 is fixedly connected to the middle position inside the drum body 1, which can be used to increase the structural rigidity and strength of the drum body 1 and resist bending and torsional stress during operation. The positioning holes 10 are circular holes arranged at equal angles on the reinforcing plate 2 and the positioning plate 702, which are used to position the winding member 9.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the blocking plate 5 includes a plate body 501 and a positioning hub 502 fixedly connected to the middle part of the outer side of the plate body 501. The plate body 501 and the positioning hub 502 are both sleeved on the adjusting cylinder 4. A mounting hole 503 is provided on the circumferential side of the positioning hub 502. The mounting holes 503 are multiple mounting holes 503 arranged in a circumferentially uniform array on the circumferential side of the positioning hub 502. The mounting holes 503 are threaded holes that can be used to receive a limiting member. When the limiting member is installed in the hole 503, it can prevent the adjusting cylinder 4 from axially moving relative to the blocking plate 5, thereby accurately limiting the working position of the adjusting cylinder 4.

[0034] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the rotating assembly 7 includes a rotating plate 701 sleeved on the surface of the adjusting cylinder 4, and a positioning plate 702 is rotatably connected to one side of the rotating plate 701. The positioning plate 702 is fixedly mounted on the inner wall of the drum body 1, and a tooth groove 703 is provided on the other side of the rotating plate 701. The circumference of the positioning plate 702 is mounted to the inner wall of the drum body 1 by bolts, which is convenient for timely installation and removal of the positioning plate 702. The rotating plate 701 and the positioning plate 702 are rotatably connected. Since the positioning plate 702 is mounted to the inner wall of the drum body 1 by bolts, it can be used for precise positioning installation during installation. At the same time, the rotating plate 701 and the positioning plate 702 are evenly distributed in the drum body 1, which evenly strengthens the structural rigidity and strength of the drum body 1 and prevents the drum body 1 from being damaged by external pressure.

[0035] A through hole 7010 is provided in the middle of the rotating plate 701, and the through hole 7010 is adapted to the shape of the adjusting cylinder 4. First slots 7011 are provided on both sides of the inner wall of the through hole 7010, and second slots 7012 are provided on the top and bottom of the inner wall of the through hole 7010, respectively. The first slot 7011 is located on opposite sides of the inner wall of the through hole 7010, and the second slot 7012 is a groove extending along the axial direction, located at the top and bottom of the inner wall of the through hole 7010. The rotating plate 701 can be assembled with the adjusting cylinder 4 through the first slot 7011 and the second slot 7012, so that the rotating plate 701 can rotate following the adjusting cylinder 4.

[0036] Specifically, such as Figure 7 As shown, the adjusting cylinder 4 includes a cylinder 401 sleeved on the surface of the main shaft 3, and first clamping blocks 402 adapted to the first clamping groove 7011 are fixedly provided on both sides of the outer surface of the cylinder 401, and the second clamping block 403 and the third clamping block 404 adapted to the second clamping groove 7012 are fixedly connected to the top and bottom of the cylinder 401 near both ends respectively, wherein the surface of the cylinder 401 is sleeved with two groups of rotating components 7 (denoted as A1 and A2) arranged from the opening of the drum body 1 to the center, and the rotating plates 701 in the two groups of rotating components 7 are in a clamping state with the two first clamping grooves 7011 and the two groups of first clamping blocks 402 on the surface of the cylinder 401 when they are not rotating. When the two groups of rotating plates 701 need to rotate at the same time, the cylinder 401 is manually rotated, and the rotating cylinder 401 can simultaneously drive the two rotating plates 701 to rotate through the two groups of first clamping blocks 402;

[0037] The axial spacing of the second clamping block 403 relative to the first clamping block 402 is greater than the axial spacing of the third clamping block 404 relative to the first clamping block 402. When the two groups of rotating plates 701 need to rotate separately, the cylinder 401 is pushed toward the inside of the drum body 1, and then the two groups of first clamping blocks 402 on the surface of the cylinder 401 are disengaged from the first clamping grooves 7011 in two groups of rotating components 7 (A1 and A2). Then, when the two groups of first clamping blocks 402 are disengaged from the first clamping grooves 7011 in the two groups of rotating components 7 (A1 and A2), the third clamping block 404 is inserted into the second clamping groove 7012 in one group of rotating components 7 (A2) at the same time of disengagement, and then the cylinder is rotated. 401, under the action of the third clamping block 404, the cylinder 401 rotates to drive the rotating plate 701 in one group of rotating components 7 (A2) to rotate, and then the cylinder 401 is pushed into the inside of the drum body 1 again, so that the second clamping block 403 is inserted into the second clamping groove 7012 in the other group of rotating components 7 (A1), and then the cylinder 401 is rotated. Under the action of the second clamping block 403, the cylinder 401 rotates to drive the rotating plate 701 in the other group of rotating components 7 (A1) to rotate, and then under the action of the second clamping block 403 and the third clamping block 404, the rotating plates 701 in the two groups of rotating components 7 (A1 and A2) can be rotated respectively;

[0038] A limiting hole 405 is provided on the outer surface of the cylinder 401, and the limiting hole 405 is internally threadedly connected to a limiting bolt 11, which is inserted into the mounting hole 503 of the positioning hub 502. The limiting hole 405 and the mounting hole 503 have matching specifications. By screwing the limiting bolt 11 into the limiting hole 405 and the mounting hole 503, the cylinder 401 and the positioning hub 502 can be locked to prevent accidental displacement of the cylinder 401.

[0039] Specifically, such as Figure 4 and Figure 5 As shown, the winding member 9 includes a first winding rod 901 and a second winding rod 902, and the first winding rod 901 and the second winding rod 902 are respectively arranged near the positioning holes 10 of the reinforcement plate 2 and the positioning plate 702, wherein the anti-slip belt 8 is wrapped around the surface of the first winding rod 901, and the length of the wrapping is longer than the anti-slip belt 8 exposed outside the roller body 1, and then the first winding rod 901 and the second winding rod 902 can rotate synchronously. When the first winding rod 901 and the second winding rod 902 rotate synchronously, the anti-slip belt 8 can be released and collected at the same time, thereby facilitating the centralized collection of partially worn anti-slip belts 8.

[0040] The ends of the first winding rod 901 and the second winding rod 902 are provided with a baffle 903 at one end, and the other side of the baffle 903 is fixedly connected to a gear 904, and the gear 904 is meshed with the tooth groove 703 on the rotating plate 701. When the rotating plate 701 rotates, it can drive the tooth groove 703 to rotate, and then the tooth groove 703 rotates to drive the two gears 904 connected to one end of the first winding rod 901 or the second winding rod 902 to rotate, and then the two gears 904 rotate to drive the first winding rod 901 or the second winding rod 902 to rotate, and then the first winding rod 901 rotates to release the anti-slip belt 8 wrapped around the surface, and then the second winding rod 902 rotates to reel up the severely worn anti-slip belt 8 exposed to the outside, and the loosening and tightening serve to transport the anti-slip belt 8, and then the severely worn anti-slip belt 8 is replaced, which greatly reduces the time of manual replacement and improves the efficiency of replacement.

[0041] Specifically, such as Figure 4 and Figure 5 As shown, a portion of the anti-slip belt 8 is wound around the first winding rod 901, and the anti-slip belt 8 located between the first winding rod 901 and the second winding rod 902 is in a tensioned state; the other ends of the first winding rod 901 and the second winding rod 902 can be inserted into the interior of the positioning hole 10, and the first winding rod 901 rotates clockwise, which will wind up the anti-slip belt 8 on the surface to release it, and at the same time drive the second winding rod 902 to rotate clockwise accordingly to tighten the other end, so that the section of the anti-slip belt 8 exposed in the embedded groove 6 is always tightened, thereby preventing the anti-slip belt 8 in the embedded groove 6 from loosening and affecting the anti-slip effect.

[0042] Working principle: After the drum body 1 has been used for a period of time, the surface of the drum body 1 is divided into four anti-slip areas at equal distances. At the same time, two groups of rotating components 7 are respectively provided on both sides of the reinforcing plate 2 (arranged from the opening of the drum body 1 to the center and marked as A1 and A2). Therefore, four groups of rotating components 7 (A1, A2, A2, A1) are provided inside the drum body 1. The four groups of rotating components 7 correspond to the four anti-slip areas. When the anti-slip belt 8 in one of the four anti-slip areas corresponding to the four groups of rotating components 7 (A1, A2, A2, A1) is worn, the limit bolt 11 is swung out to push the drum body 401 into the inside of the drum body 1, and then the two groups of first blocks 402 on the surface of the drum body 401 are disengaged from two of them. The first card slot 7011 of the two rotating components 7 (A1, A2 or A2, A1) is inserted into the first card slot 7011 of the two rotating components 7 (A1, A2 or A2, A1). Then, when the two groups of first card blocks 402 are disengaged from the first card slot 7011 of the two rotating components 7 (A1, A2 or A2, A1), the third card block 404 is inserted into the second card slot 7012 of one of the rotating components 7 (A2). Then, the cylinder 401 is rotated. Under the action of the third card block 404, the cylinder 401 rotates to drive the rotating plate 701 in one of the rotating components 7 (A2) to rotate. Then, the cylinder 401 is pushed toward the inside of the drum body 1 again, so that the second card block 403 is inserted into the second card slot 7012 of the other rotating component 7 (A1). Then The cylinder 401 is rotated, and under the action of the second clamping block 403, the cylinder 401 rotates to drive the rotating plate 701 in the other rotating assembly 7 (A1) to rotate, and then under the action of the second clamping block 403 and the third clamping block 404, the rotating plates 701 in the two rotating assemblies 7 (A1, A2 or A2, A1) can be rotated respectively, and then when the rotating plate 701 rotates, it can drive the tooth groove 703 to rotate, and then the tooth groove 703 rotates to drive the two gears 904 connected to one end of the first winding rod 901 or the second winding rod 902 to rotate, and then the two gears 904 rotate to drive the first winding rod 901 or the second winding rod 902 to rotate, and then when the first winding rod 901 rotates, The anti-slip belt 8 wrapped around the surface is released, and then the second winding rod 902 rotates to rewind the severely worn anti-slip belt 8 exposed on the outside. The loosening and tightening serve to transport the anti-slip belt 8, and then the severely worn anti-slip belt 8 is replaced. When the first winding rod 901 and the second winding rod 902 rotate synchronously, the anti-slip belt 8 can be released and collected at the same time, which is convenient for centralized collection of partially worn anti-slip belts 8, greatly reducing the time for manual replacement and improving the replacement efficiency. At the same time, when the anti-slip belt 8 in a certain anti-slip area is completely worn, the blocking plate 5 and the positioning plate 702 are removed from the drum body 1 in turn, and then the anti-slip belt 8 in a certain anti-slip area can be partially replaced, thereby reducing costs.

[0043] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can replace or change the anti-slip roller for a vehicle-mounted conveyor and its inventive concept according to the technology of the present invention, which should be covered by the scope of protection of the present invention.
