Description

Technical Field

[0001] This utility model relates to the field of mining transportation equipment, and in particular to a driving device for a mining conveyor. Background Technology

[0002] In the field of mining transportation equipment, mining conveyors are the core equipment for the efficient transfer of materials such as ore. The stability and safety of their drive units directly affect mining production efficiency and operational safety. Existing mining conveyor drive units have significant defects in their braking mechanisms: most employ a single rigid braking method, resulting in large instantaneous impact forces that easily lead to accelerated wear of components such as gears and brake pads, shortening the equipment's lifespan; furthermore, they lack a flexible brake pad switching mechanism, and prolonged operation of a single brake pad can easily cause overheating, leading to decreased braking performance and even machine shutdown. Simultaneously, the traditional device's moving block limiting structure is not perfect, prone to deviation during braking, affecting braking accuracy and failing to meet the high reliability and long service life requirements of conveyor drive units under complex mining conditions.

[0003] A search revealed patent publication number CN217296923U, which discloses a mining conveyor in the field of mining equipment. The conveyor includes a counterweight plate. Two bending plate frames are fixedly connected to the upper ends of the counterweight plate. Rotating rods are rotatably connected to the bottom of the vertical plate and the right end of the horizontal plate of the bending plate frames. Transmission gears are fixedly connected to both ends of the rotating rods. A driven gear is rotatably connected to the middle bend of the bending plate frames. The transmission gear and the driven gear are connected by a chain drive. This mining conveyor, with its bent shape, places the vertical portion of the counterweight plate and bending plate frames at the edge of a low-lying area, while the horizontal portion of the bending plate frames is placed at a higher point. It uses a hopper for bending and conveying, significantly reducing the space occupied by the conveyor when transporting minerals and making it more convenient for personnel to work in low-lying areas.

[0004] While existing technologies can achieve certain transportation effects, they also have drawbacks: the lack of graded buffer braking in existing devices leads to easy damage to components, and the lack of flexible brake pad switching causes overheating failure and frequent shutdowns. In view of this, we propose a mining conveyor drive device that solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a driving device for a mining conveyor.

[0006] The technical solution of this utility model is as follows: A driving device for a mining conveyor includes a mounting frame and a moving block. Two symmetrical moving blocks are provided on one outer wall of the mounting frame. A threaded seat is fixedly connected to one outer wall of the mounting frame. A threaded rod is provided in the threaded seat. The rotation center of one end of the threaded rod is fixedly connected to the output shaft of a first rotating motor. The first rotating motor is fixedly connected to one outer wall of the moving block. The other end of the threaded rod is connected to another moving block through a bearing, driving the first rotating motor to adjust the position of the moving block.

[0007] When using a mining conveyor drive device in this solution, a second rotating motor is driven to move the conveyor belt. When the conveyor reaches its destination, a first rotating motor is driven to move the moving block, causing one side of the brake pad to contact the gear. The gear is then decelerated by friction. During the contact between the brake pad and the gear, the brake pad is initially supported by spring force, which initially decelerates the gear. Subsequently, a pressure sensor transmits a signal to the controller. The controller, based on the pressure magnitude, controls the hydraulic cylinder to supply hydraulic oil to the hydraulic cylinder to provide support force for the hydraulic rod against the brake pad, thus rigidly braking the gear. When the temperature of one side of the brake pad is too high, the first rotating motor is driven to adjust the moving block on the other side, causing the brake pad on that side to brake the gear.

[0008] Preferably, a guide seat is fixedly connected to the lower outer wall of the mounting bracket, and a connecting rod is provided inside the guide seat. The two ends of the connecting rod are fixedly connected to two moving blocks respectively. The connecting rod limits the movement of the moving blocks to prevent them from deflecting during movement.

[0009] Preferably, two symmetrical hydraulic cylinders are fixedly connected to one side of the outer wall of the movable block. Each hydraulic cylinder has a hydraulic rod inside, and the hydraulic rod is fixedly connected to one side of the outer wall of the brake pad. The hydraulic cylinder and the hydraulic rod provide rigid support force for the brake pad.

[0010] Preferably, one side of the outer wall of the brake pad is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to one side of the outer wall of the moving block. Multiple pressure sensors are provided on one side of the outer wall of the brake pad, and the spring provides flexible support force for the brake pad.

[0011] Preferably, a hydraulic cylinder is fixedly connected to one outer wall of the movable block, a pump body is fixedly connected to one outer wall of the hydraulic cylinder, a connecting pipe is provided on one side of the pump body, the connecting pipe is connected to the hydraulic cylinder, a controller is fixedly connected to one outer wall of the hydraulic cylinder, and hydraulic oil is stored in the hydraulic cylinder and is pumped into the hydraulic cylinder through the pump body.

[0012] Preferably, the outer wall of one side of the mounting frame is fixedly connected to the output shaft of a second rotating motor, which is fixedly connected to the rotation center of one side of the conveyor belt, thereby driving the second motor to enable the conveyor belt to perform transportation operations.

[0013] Preferably, the rotation center on the other side of the conveyor belt is fixedly connected to a gear, and the gear is located between the threaded seat and the guide seat.

[0014] Preferably, the outer wall of one side of the mounting bracket is provided with multiple guide rails, and the movable block is disposed inside the guide rails on one side. The guide rails restrict the guide rails to prevent them from excessive displacement.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. In the initial contact between the brake pad and the gear, the spring first provides flexible support force to achieve initial deceleration of the gear, effectively buffering the impact force at the moment of contact and avoiding damage to the brake pad and gear caused by rigid collision; then the pressure sensor transmits the contact pressure signal to the controller, and the controller controls the oil cylinder to deliver hydraulic oil to the hydraulic cylinder according to the pressure, so that the hydraulic rod pushes the brake pad to provide rigid support force, realizing precise and efficient strong braking, ensuring that the transport machine stops quickly and smoothly, and improving the safety and stability of braking.

[0017] Second, based on the first beneficial effect, the position of the moving block can be flexibly adjusted by driving the first rotating motor, enabling the switching of the two brake pads. When one brake pad becomes too hot due to prolonged braking, it can be switched to the other brake pad for braking in a timely manner. This avoids the problem of accelerated wear, decreased braking performance, or even failure caused by a single brake pad continuously being overheated, thus extending the service life of the brake pads, reducing equipment downtime, ensuring the continuous and stable operation of the mining conveyor, and improving overall work efficiency.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Please see Figures 1-4 As shown, this embodiment is a driving device for a mining conveyor, including a mounting frame 2 and a movable block 6. Two symmetrical movable blocks 6 are provided on one outer wall of the mounting frame 2. A threaded seat 4 is fixedly connected to one outer wall of the mounting frame 2. A threaded rod 5 is provided inside the threaded seat 4. The rotation center of one end of the threaded rod 5 is fixedly connected to the output shaft of the first rotating motor 3. The first rotating motor 3 is fixedly connected to one outer wall of the movable block 6. The other end of the threaded rod 5 is connected to the other movable block 6 through a bearing. In use, the first rotating motor 3 is started to drive the threaded rod 5 to rotate. Since the threaded seat 4 is fixed to the mounting frame 2, the rotational motion of the threaded rod 5 is converted into linear motion of the movable block 6 along the axial direction of the threaded rod 5, thereby realizing the synchronous relative or opposite movement of the two movable blocks 6 to adjust the contact position between the brake pad 15 and the gear 8.

[0031] Example 2

[0032] Please see Figures 1-4As shown, this embodiment further includes, based on embodiment 1, a guide seat 9 fixedly connected to the lower outer wall of the mounting bracket 2. A connecting rod 10 is provided inside the guide seat 9. The two ends of the connecting rod 10 are fixedly connected to two moving blocks 6 respectively. In use, when the moving blocks 6 move under the drive of the threaded rod 5, the connecting rod 10 slides synchronously in the guide seat 9, providing auxiliary support and guidance for the moving blocks 6, ensuring that the moving blocks 6 maintain a stable posture during movement, preventing deflection due to uneven force, thereby ensuring the contact accuracy between the brake pad 15 and the gear 8.

[0033] Two symmetrical hydraulic cylinders 12 are fixedly connected to one side of the outer wall of the moving block 6. The hydraulic cylinder 12 is equipped with a hydraulic rod 14. The hydraulic rod 14 is fixedly connected to one side of the outer wall of the brake pad 15. When it is needed to brake the conveyor, the hydraulic system injects hydraulic oil into the hydraulic cylinder 12, pushes the hydraulic rod 14 to extend, and then makes the brake pad 15 contact the gear 8. The friction force is used to brake the gear 8, and finally the conveyor belt 1 stops running.

[0034] One side of the brake pad 15 is fixedly connected to one end of the spring 13, and the other end of the spring 13 is fixedly connected to one side of the outer wall of the moving block 6. Multiple pressure sensors 16 are provided on one side of the outer wall of the brake pad 15. During use, when the brake pad 15 first contacts the gear 8, the spring 13 is compressed, providing an initial flexible braking force to prevent damage to the gear 8 or brake pad 15 due to rigid contact. Simultaneously, the pressure sensors 16 detect the contact pressure between the brake pad 15 and the gear 8 in real time and transmit the pressure signal to the controller 19.

[0035] A hydraulic cylinder 20 is fixedly connected to one side of the outer wall of the movable block 6. A pump body 18 is fixedly connected to one side of the outer wall of the hydraulic cylinder 20. A connecting pipe 17 is provided on one side of the pump body 18, which is connected to the hydraulic cylinder 12. A controller 19 is fixedly connected to one side of the outer wall of the hydraulic cylinder 20. When in use, after receiving the signal from the pressure sensor 16, the controller 19 controls the pump body 18 to draw hydraulic oil from the hydraulic cylinder 20 according to the preset braking parameters, and delivers it to the hydraulic cylinder 12 through the connecting pipe 17. The controller precisely adjusts the thrust of the hydraulic rod 14, thereby realizing the dynamic adjustment of the braking force of the brake pad 15 and ensuring that the braking process is smooth and reliable.

[0036] The output shaft of the second rotating motor 11 is fixedly connected to the outer wall of one side of the mounting frame 2 and is fixedly connected to the rotation center of the conveyor belt 1. When the second rotating motor 11 is started, its output shaft drives the drive wheel of the conveyor belt 1 to rotate. Through the friction between the conveyor belt 1 and the drive wheel and the driven wheel, the conveyor belt 1 achieves cyclical movement, thereby completing the transportation task of materials such as ore.

[0037] The rotation center on the other side of the conveyor belt 1 is fixedly connected to the gear 8. The gear 8 is located between the threaded seat 4 and the guide seat 9. When it is necessary to stop the conveyor belt 1 during use, the position of the moving block 6 is adjusted by the first rotating motor 3 so that the brake pad 15 contacts the gear 8. The friction force is used to decelerate the gear 8 until it stops rotating, thereby achieving the braking of the conveyor belt 1. The position design of the gear 8 ensures that the brake pad 15 can effectively act on the gear 8, while avoiding interference with other components.

[0038] The mounting bracket 2 has multiple guide rails 7 on one side of its outer wall. The movable block 6 is located inside the guide rail 7 on one side. During use, the guide rail 7 restricts the displacement of the movable block 6 in the direction parallel to the threaded rod 5 to prevent the movable block 6 from displacing excessively.

[0039] Instructions for use: When in use, the second rotating motor 11 drives the conveyor belt 1 to move. When the conveyor belt reaches its destination, the first rotating motor 3 drives the moving block 6 to move, causing one side of the brake pad 15 to contact the gear 8. The friction force slows down the gear 8. During the contact between the brake pad 15 and the gear 8, the brake pad 15 is first supported by the force of the spring 13, which initially slows down the gear 8. Then, the pressure sensor 16 transmits a signal to the controller 19. The controller 19 controls the oil cylinder 20 to deliver hydraulic oil to the hydraulic cylinder 12 according to the pressure, so as to provide the hydraulic rod 14 with the support force for the brake pad 15 and perform rigid braking on the gear 8. When the temperature of one side of the brake pad 15 is too high, the first rotating motor 3 is driven to adjust the moving block 6 on the other side, so that the brake pad 15 on that side brakes the gear 8.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
