Description

Technical Field

[0001] This utility model relates to the technical field of head wheel turning equipment, and in particular to a head wheel turning device for a belt elevator. Background Technology

[0002] In the production process of cement manufacturing enterprises, belt elevators are indispensable core equipment. However, a prominent problem often exists during their operation: the relative displacement between the head pulley and the belt causes severe wear on the rubber-coated tiles of the head pulley. Once the rubber-coated tiles of the belt elevator's head pulley are worn, it is impossible to ensure that the stress point of the conveyor belt is always on the center line of the head pulley, leading to belt deviation, wear on the elevator casing, damage to the buckets, and other equipment malfunctions. The traditional solution to this problem is to replace the rubber-coated tiles of the belt conveyor's head pulley. However, this method not only directly increases the production cost of enterprises, but also increases the workload of equipment maintenance personnel, which is not conducive to improving production efficiency. In order to save costs, the rubber-coated tiles can also be ground by grinding and turning. However, the transmission grinding device relies on manual labor, which may cause the belt to deviate further due to uneven grinding. Even if there is turning equipment, it is impossible to achieve automated grinding of rubber-coated tiles. It has poor applicability, cannot grind different belt elevators, and cannot automatically adjust the turning thickness. Therefore, we propose a belt elevator head wheel turning device to solve the above problems. Utility Model Content

[0003] This utility model provides a head wheel turning device for a belt elevator, which solves the problems of low applicability, inability to achieve automated turning, and inability to automatically adjust the turning thickness of traditional head wheel turning devices.

[0004] This utility model provides a turning device for the head wheel of a conveyor belt lifter, including a bracket. The bracket has a first sliding groove and a second sliding groove on its upper and lower surfaces, respectively. A first screw is rotatably installed in the first sliding groove, driven by a first motor mounted on the side of the bracket. Two support plates pass through the first screw, slidably embedded in the first sliding groove. A fixing block is installed on the support plate, and a groove is formed on the fixing block. A moving block is slidably embedded in the groove. A second screw passes through the bottom of the moving block, driven by a second motor mounted on the bottom of the fixing block. A turning device is installed on the fixing block. A bidirectional screw is rotatably installed in the second sliding groove, with an operating disc installed at one end of the bidirectional screw. Clamping devices are symmetrically installed on the bidirectional screw.

[0005] Preferably, the clamping device includes a clamping block sleeved on a bidirectional screw, the clamping block being slidably embedded in a second sliding groove, a slot being formed on the clamping block, a third screw passing through the bottom surface of the slot, a pressure plate being installed at the upper end of the third screw, and a rotating disk being installed at the lower end of the third screw.

[0006] Preferably, the turning device includes a support bar mounted on the fixed block, and a turning tool is mounted on the support bar.

[0007] Preferably, brushes are also installed at both ends of the support bar.

[0008] Preferably, waste boxes are mounted on both sides of the fixing block.

[0009] Preferably, the first motor and the second motor are servo motors.

[0010] As can be seen from the above technical solution, this utility model provides a turning device for the head wheel of a conveyor belt elevator. In use, first adjust the operating disc, which drives the bidirectional screw to rotate, so that the slot on the clamping block is precisely engaged with the support frame on the conveyor belt elevator. Twisting the rotating disc causes the pressure plate to move forward via the third screw until the pressure plate is pressed tightly against the support frame. At this point, the installation of the device is complete. In use, first start the second motor, which drives the second screw to rotate, thereby adjusting the height of the moving block and simultaneously changing the cutting tool mounted on the moving block. The height of the cutting tool is adjusted until it reaches the predetermined cutting height. At this point, the cutting operation begins. During cutting, the first motor is started, which drives the first screw to rotate, causing the fixed block to move slowly along the first screw. First, the brush on one side of the support bar contacts the rubber-coated tile and cleans it. Then, the cutting tool contacts the rubber-coated tile and cuts it. A large amount of debris is generated during cutting. At this time, the brush on the other side contacts the rubber-coated tile and sweeps away the adhesive debris on the surface. The debris cleaned by the brushes on both sides will eventually fall into the waste box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The automatic turning of the rubber-coated tile can be achieved through the cooperation of the first motor, the first screw and the support plate, which can ensure the consistency of turning and significantly improve the turning quality of the rubber-coated tile. 2. Through the cooperation of the second motor, the second screw and the moving block, the turning height of the turning device can be automatically adjusted, and the turning thickness of the rubber-coated tile can be precisely controlled. 3. The clamping device secures various types of belt hoists, significantly increasing its versatility and maintaining equipment stability during turning, thus improving the quality of turning.

[0012] In summary, this application can be used to machine various types of rubber-coated sheets for conveyor belt elevators, demonstrating high versatility. It can also achieve automatic and stable machining, significantly improving machining quality and ensuring the stability of the belt during operation. Furthermore, it can automatically adjust the machining thickness as needed to ensure the conveyor belt elevator reaches its optimal working state. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] See Figure 1-4A head wheel turning device for a conveyor belt hoist is disclosed, applied in the field of head wheel turning equipment technology. It can turn various types of rubber-coated sheets for conveyor belt hoists, achieving automatic and stable turning operations, and can automatically adjust the turning thickness as needed. Specifically, it includes a bracket 1, with a first groove 2 and a second groove 3 on its upper and lower surfaces, respectively. Both grooves are rectangular holes. A first screw 4 is rotatably installed within the first groove 2. The first screw 4 is driven by a first motor 5 installed on the side of the bracket 1. The first screw 4 passes from the leftmost to the rightmost end of the first groove 2, and is connected to the first motor 5 on either side. To ensure precise control, the first motor 5 is a servo motor. Two support plates 6 pass through the first screw 4, slidingly embedded within the first groove 2. During operation, the first motor 5 drives the first screw 4 to rotate, causing the support plates 6 fitted onto the first screw 4 to move along the first groove 2. The size needs to fit perfectly into the first slide groove 2 to prevent wobbling when the support plate 6 moves. A slide rail can also be added to the first slide groove 2 to make the movement of the support plate 6 smoother. A fixing block 7 is installed on the support plate 6, with two support plates 6 located on either side of the bottom of the fixing block 7, leaving space for the installation of the second motor 11 at the bottom of the fixing block 7. A rectangular groove 8 is formed on the fixing block 7, and a movable block 9 is slidably embedded within it. To allow the movable block 9 to move normally within the groove 8, the size of the movable block 9 must be the same as the size of the groove 8. To improve the smoothness of the movable block 9's up-and-down movement, an additional movable block 9 can be added within the groove 8. Correspondingly, a second screw 10 passes through the bottom of the moving block 9. The second screw 10 is driven by a second motor 11 installed at the bottom of the fixed block 7. The second motor 11 is a servo motor, which can achieve precise control of the height of the moving block 9. When the second motor 11 is started, it drives the second screw 10 to rotate, thereby driving the moving block 9 to move up and down along the groove 8. A turning device is installed on the fixed block 7. The movement of the fixed block 7 will drive the turning device to move synchronously, thereby changing the turning height. When turning the rubber-coated tile 25, the turning thickness can also be adjusted in real time by rotating the second motor 11, because the belt elevator 2 3. Due to the heavy load in the middle, to ensure stability, the sides of the rubber-coated tile 25 can be thinned, while the middle is left thicker to increase the wear resistance of the middle of the rubber-coated tile 25. A bidirectional screw 12 is rotatably installed in the second slide groove 3. The bidirectional screw 12 passes from the leftmost to the rightmost side of the second slide groove 3. An operating plate 13 is installed at one end of the bidirectional screw 12. Clamping devices are symmetrically installed on the bidirectional screw 12. When in use, the operating plate 13 is rotated, which drives the bidirectional screw 12 to rotate, thereby driving the clamping devices to move along the bidirectional screw 12. By adjusting the distance between the two clamping devices, this device can be installed on belt elevators 23 of different widths.When in use, this application can be installed on belt elevators 23 of different models and sizes, which has high applicability. Furthermore, the machining thickness of the coated tile 25 can be adjusted according to the actual use, avoiding frequent replacement of the coated tile 25 and significantly reducing production costs.

[0018] In this invention, the clamping device includes a clamping block 14 sleeved on the bidirectional screw 12. The clamping block 14 is slidably embedded in the second sliding groove 3, and the size of the clamping block 14 corresponds to the second sliding groove 3 to prevent the clamping block 14 from shaking during movement. The clamping block 14 has a slot 15, and a third screw 16 passes through the bottom surface of the slot 15. A pressure plate 17 is installed at the upper end of the third screw 16, and a rotating disk 18 is installed at the lower end of the third screw 16. In use, adjusting the operating disk 13 drives the bidirectional screw 12 to rotate, so that the slot 15 on the clamping block 14 is just locked onto the support frame 24 on the conveyor belt elevator 23. If the conveyor belt elevator 23 does not have a support frame 24, a support frame 24 of any size can be installed. Twisting the rotating disk 18 causes the rotating disk to drive the pressure plate 17 forward through the third screw 16 until the pressure plate 17 is pressed tightly against the support frame 24. In this utility model, the turning device includes a support bar 19 mounted on a fixed block 7, and a turning tool 20 is mounted on the support bar 19. The turning tool 20 can be replaced as needed for turning. When the conveyor belt elevator 23 is working, the rubber-coated tile 25 rotates continuously. When the rubber-coated tile 25 comes into contact with the turning tool 20, it can be turned and polished flat. Brushes 21 are also installed at both ends of the support strip 19. The brush 21 on one side of the support strip 19 first contacts the coated tile 25 and cleans the coated tile 25. Then the cutting tool 20 contacts the coated tile 25 and turns the coated tile 25. A lot of debris will be generated during the turning. At this time, the brush 21 on the other side contacts the coated tile 25 and sweeps away the adhesive debris on the surface. Waste boxes 22 are hung on both sides of the fixing block 7. The debris cleaned by the brushes 21 on both sides will eventually fall into the waste box 22. The waste box 22 adopts a hanging mode, which makes it convenient to remove and clean at any time.

[0019] As can be seen from the above technical solution, during use, first adjust the operating disc 13. The operating disc 13 drives the bidirectional screw 12 to rotate, so that the slot 15 on the clamping block 14 is just locked onto the support frame 24 on the conveyor belt elevator 23. Turn the rotating disc 18, and the rotating disc drives the pressure plate 17 to move forward through the third screw 16 until the pressure plate 17 is pressed against the support frame 24. At this time, the installation of this equipment is completed. During use, first start the second motor 11. The second motor 11 drives the second screw 10 to rotate, thereby adjusting the height of the moving block 9 and changing the height of the cutting tool 20 installed on the moving block 9 until the cutting tool 20 is adjusted. When the height reaches the predetermined turning height, the turning operation begins. During turning, the first motor 5 is started, which drives the first screw 4 to rotate, causing the fixed block 7 to move slowly along the first screw 4. First, the brush 21 on one side of the support bar 19 contacts the rubber-coated tile 25 and cleans the rubber-coated tile 25. Then, the cutting tool 20 contacts the rubber-coated tile 25 and turns it. A large amount of debris is generated during turning. At this time, the brush 21 on the other side contacts the rubber-coated tile 25 and sweeps away the adhesive debris on the surface. The debris cleaned by the brushes 21 on both sides will eventually fall into the waste box 22.
