Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and in particular to a side limiting roller for preventing deviation of a mining conveyor belt. Background Technology

[0002] Mining conveyor belts are specialized conveying equipment used in the mining industry, primarily for transporting bulk materials such as coal and ore. They are typically made of high-strength rubber or polyurethane materials, possessing characteristics such as wear resistance, tear resistance, and impact resistance, enabling them to operate stably for extended periods in harsh working environments. However, conveyor belts may experience deviation during operation, which not only reduces conveying efficiency but also causes material leakage and may even damage the conveyor belt and related equipment. Therefore, limit rollers are needed to limit the lateral movement of the conveyor belt, preventing it from shifting laterally and thus maintaining stable operation and improving conveying efficiency.

[0003] Existing methods for preventing conveyor belt misalignment mostly involve using fixed vertical rollers that make hard contact with the edge of the conveyor belt. The limiting position of the fixed vertical rollers is not only difficult to adjust appropriately according to the needs of the conveyor belt, but the fixed vertical rollers also experience wear. In particular, when multiple fixed vertical rollers have different degrees of wear, the disassembly of the corresponding fixed vertical rollers is also quite inconvenient.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The main purpose of this utility model is to provide a side limiting roller for preventing deviation of mining conveyor belts, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A side-limiting roller for preventing deviation of a mining conveyor belt includes a first seat, a second seat, and a support seat. A conveying device is installed between the first and second seats. A servo motor is fixedly installed on the left front end of the first seat, and a controller is fixedly installed on the right front end of the first seat. There are two support seats, and two mounting brackets are fixedly installed on one end of each of the two support seats. Several limiting devices are fixedly installed between each pair of the four mounting brackets.

[0008] Preferably, the limiting device includes two mounting bases. Each mounting base has a screw hole at one opposite end, and a roller is rotatably mounted between the two mounting bases. A polyurethane layer is fixedly mounted on the outer surface of the roller. Several screws are installed at one opposite end of each mounting base, and several through-holes are opened at the corresponding end of each mounting base. The two mounting bases are respectively fixedly mounted on the two mounting brackets by screws. The rollers limit the movement of both sides of the conveyor belt. Furthermore, the polyurethane layer on the outer surface of the rollers maintains good elasticity and resilience even under high hardness, effectively absorbing impact energy for shock absorption and cushioning, thereby improving the service life of the device. Moreover, by loosening the screws on the mounting brackets, the more worn rollers can be disassembled and replaced through the through-holes.

[0009] Preferably, the conveying device includes a conveyor belt, with drive rollers inserted at both the left and right ends of the conveyor belt. The left drive roller is fixedly connected to the output end of a servo motor. Two limit frames are fixedly installed on the outer surfaces of both drive rollers. Several support rollers are inserted at the left end of the conveyor belt. The two drive rollers and the support rollers are rotatably mounted between a first seat and a second seat. The servo motor drives the drive rollers, which in turn drive the conveyor belt to transport materials. Furthermore, the design of the limit frames on the drive rollers also provides a certain degree of limitation for the conveyor belt.

[0010] Preferably, four hydraulic cylinders are fixedly installed at the upper front end of the support base, and the output ends of the four hydraulic cylinders are jointly fixedly installed on a mounting frame. The controller controls the extension and retraction of the hydraulic cylinder output ends, thereby enabling the mounting frame to move the rollers on the mounting frame, allowing the position of the rollers to be adjusted appropriately according to the degree of conveyor belt offset.

[0011] Preferably, the polyurethane layer is in contact with the conveyor belt.

[0012] Preferably, the fixing frame is U-shaped, and the two mounting brackets are fixed to the upper and lower rear ends of the fixing frame, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The mining materials to be transported are placed on the conveyor belt of the conveyor device. Then, the servo motor drives the drive roller, which in turn drives the conveyor belt to transport the materials. At this time, the rollers on the limiting device limit the two sides of the conveyor belt. In addition, the design of the upper limit frame on the drive roller can also limit the conveyor belt to a certain extent, thereby preventing the conveyor belt from deviating significantly. Moreover, the outer surface of the roller is provided with a polyurethane layer, whose wear resistance is 5 to 10 times that of natural rubber. At the same time, the polyurethane elastomer can maintain its shape and performance under high loads without permanent deformation or tearing. Even under very high hardness, polyurethane can still maintain good elasticity and resilience, effectively absorbing impact energy for shock absorption and cushioning, thereby improving the service life of the device. Furthermore, by loosening the screws on the mounting bracket, the worn rollers can be disassembled and replaced through the port.

[0015] 2. The hydraulic cylinder output end is controlled by the controller to extend and retract, thereby enabling the fixed frame to drive the rollers on the mounting frame to move. The position of the rollers can be adjusted appropriately according to the degree of conveyor belt offset, thus improving the practicality of the device. Attached Figure Description

[0024] like Figures 1-4 As shown, a side-limiting roller for preventing deviation of a mining conveyor belt includes a first seat 1, a second seat 5, and a support seat 4. A conveying device 3 is installed between the first seat 1 and the second seat 5. A servo motor 6 is fixedly installed on the left front end of the first seat 1, and a controller 7 is fixedly installed on the right front end of the first seat 1. There are two support seats 4, and two mounting brackets 8 are fixedly installed on one end of each of the two support seats 4. Several limiting devices 2 are fixedly installed between each pair of the four mounting brackets 8.

[0025] The limiting device 2 includes two mounting bases 20. Each mounting base 20 has a screw hole 21 at one of its opposite ends. A roller 22 is rotatably mounted between the two mounting bases 20. A polyurethane layer 23 is fixedly mounted on the outer surface of the roller 22. Several screws 24 are mounted on one of the opposite ends of each of the two mounting brackets 8. Several through-holes 25 are opened at the corresponding ends of each of the two mounting brackets 8. The two mounting bases 20 are respectively fixedly mounted on the two mounting brackets 8 by the screws 24. The rollers 22 limit the movement of both sides of the conveyor belt 30. Furthermore, the polyurethane layer 23 on the outer surface of the rollers 22 maintains good elasticity and resilience even under high hardness, effectively absorbing impact energy for shock absorption and cushioning, thereby improving the service life of the device. Moreover, by loosening the screws 24 on the mounting brackets 8, the worn roller 22 can be disassembled and replaced through the through-holes 25.

[0026] The conveying device 3 includes a conveyor belt 30. Drive rollers 31 are interlaced at the left and right ends of the front end of the conveyor belt 30. The left drive roller 31 is fixedly connected to the output end of the servo motor 6. Two limit frames 32 are fixedly installed on the outer surface of each drive roller 31. Several support rollers 33 are interlaced at the left end of the front end of the conveyor belt 30. The two drive rollers 31 and the support rollers 33 are rotatably mounted between seat 1 and seat 5. The polyurethane layer 23 abuts against the conveyor belt 30. The servo motor 6 drives the drive rollers 31, which in turn drive the conveyor belt 30 to transport materials. Furthermore, the design of the limit frames 32 on the drive rollers 31 also provides a certain degree of limitation for the conveyor belt 30.

[0027] Four hydraulic cylinders 40 are fixedly installed at the upper front end of the support base 4, and a fixing frame 41 is fixedly installed at the output end of the four hydraulic cylinders 40. The fixing frame 41 is U-shaped, and two mounting brackets 8 are fixed at the upper rear end and lower rear end of the fixing frame 41, respectively. The controller 7 controls the extension and retraction of the output end of the hydraulic cylinders 40, so that the fixing frame 41 can drive the roller 22 on the mounting bracket 8 to move, and the position of the roller 22 can be adjusted appropriately according to the offset of the conveyor belt 30. The electrical equipment of this utility model is all existing technology, and the electrical equipment can operate normally during trial operation. The controller 7 needs to be connected to an external power source when in use, and the controller 7 and the electrical equipment in this utility model are electrically connected.

[0028] It should be noted that this utility model is a side-limiting roller for preventing deviation of a mining conveyor belt. First, the controller 7 controls the output end of the hydraulic cylinder 40 to extend and retract, thereby enabling the fixed frame 41 to drive the roller 22 on the mounting frame 8 to move. This allows the position of the roller 22 to be adjusted appropriately according to the degree of deviation of the conveyor belt 30, thus improving the practicality of the device. Next, the mining materials to be transported are placed on the conveyor belt 30 on the conveying device 3. Then, the servo motor 6 drives the drive roller 31, which in turn drives the conveyor belt 30 to transport the materials. At this time, the roller 22 on the limiting device 2 limits the two sides of the conveyor belt 30. Additionally, the drive roller... The design of the upper limit bracket 32 ​​can also play a certain role in limiting the conveyor belt 30, thereby preventing the conveyor belt 30 from deviating significantly. Moreover, the outer surface of the roller 22 is provided with a polyurethane layer 23, which has a wear resistance 5 to 10 times that of natural rubber. At the same time, the polyurethane elastomer can maintain its shape and performance under high loads without permanent deformation or tearing. Even under very high hardness, polyurethane can still maintain good elasticity and resilience, effectively absorbing impact energy for shock absorption and cushioning, thereby improving the service life of the device. Furthermore, by loosening the screws 24 on the mounting bracket 8, the worn roller 22 can be disassembled and replaced through the port 25.
