Description

Technical Field

[0001] This utility model relates to the technical field of coal mine transportation equipment, and in particular to a material roll-off prevention device for inclined shaft belt conveyors. Background Technology

[0002] When a belt conveyor in an inclined shaft is transporting coal, gangue, or other materials upwards, and the slope of the shaft is greater than 15°, in order to prevent large pieces of coal and gangue from rolling down and injuring people during the coal transport process, and to better achieve safe production, it is necessary to install a coal and gangue rolling prevention device in the middle of the belt conveyor.

[0003] The existing utility model patent with public number CN216128830U discloses a device for preventing coal gangue from rolling down a belt conveyor in an inclined shaft. It includes two fixed frames installed on the outer walls of the top two sides of the belt conveyor. A round rod is welded to the upper part of the outer wall of the opposite side of the two fixed frames, and a baffle mechanism is rotatably connected to the middle of the round rod through a bearing. Both ends of the baffle mechanism are connected to a tension adjustment mechanism. By rotatably setting the baffle mechanism on the round rod, when coal gangue rolls down the inclined belt surface, the baffle mechanism can block the rolling coal gangue, preventing the coal gangue from hitting the equipment and personnel below.

[0004] Regarding the aforementioned prior art, the inventors believe that although the baffle mechanism of the existing anti-roll device can block and restrict the rolling heavy objects, the rolling heavy objects directly impact the baffle mechanism at high speed, which can easily cause the baffle to deform and be damaged. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a material roll-off prevention device for inclined shaft belt conveyors. By setting a buffer baffle to decelerate the rolling material, the impact on the limiting anti-roll baffle is reduced, making it less prone to deformation and damage. It also achieves graded interception of rolling materials, resulting in a better anti-roll-off effect.

[0006] To achieve the above objectives, this utility model provides a material roll-off prevention device for an inclined shaft belt conveyor. The material roll-off prevention device is installed on the supports on both sides of the belt conveyor and includes a frame, a buffer baffle, and a limiting anti-roll baffle.

[0007] The frame includes a top plate and side plates fixed to both sides of the top plate, with the bottom end of the side plates away from the top plate connected to the support of the belt conveyor.

[0009] The anti-roll baffle is provided with a limiting plate on the side away from the buffer baffle. The limiting plate is fixed to the bottom surface of the top plate. When the anti-roll baffle is flipped away from the buffer baffle, it abuts against the limiting plate.

[0010] The buffer baffle can swing back and forth along the conveyor belt direction; the buffer baffle includes a connecting plate hinged to the top plate and a main baffle detachably mounted on the connecting plate; the side wall of the main baffle of the buffer baffle is provided with a buffer pad.

[0011] Furthermore, a vibration damping assembly is provided between the buffer baffle and the top plate. The vibration damping assembly includes an arc-shaped guide rod and a damping spring. One end of the arc-shaped guide rod is fixed to the bottom surface of the top plate. A slot is provided on the side of the connecting plate near the top plate. The arc-shaped guide rod passes through the slot and is inserted into the connecting plate. The damping spring is sleeved on the outside of the arc-shaped guide rod. One end of the damping spring is fixedly connected to the bottom surface of the top plate, and the other end is fixedly connected to the side wall of the connecting plate.

[0012] Furthermore, a traction deceleration mechanism is provided on the side wall of the buffer baffle away from the limiting anti-roll baffle. The traction deceleration mechanism includes a crossbeam and an A-frame. The A-frame includes connecting rods connected at both ends. The opening of the A-frame faces away from the buffer baffle. The A-frame is mounted on the crossbeam, and the crossbeam can slide along the height direction of the buffer baffle.

[0013] Furthermore, a slider is fixed on the crossbeam, and a groove adapted to the slider is provided on the main baffle, and the slider is slidably connected to the inner wall of the groove.

[0015] Furthermore, a limiting block is provided at the bottom end of the side of the limiting anti-roll baffle away from the buffer baffle, and a rotating shaft is fixed on the limiting block. An end plate is provided on the side of the side plate near the limiting anti-roll baffle, and the rotating shaft passes through the end plate. One end of the rotating shaft is connected to a drive motor, and the drive motor is fixed on the end plate. A pressure sensor is provided on the connecting rod, and the pressure sensor is electrically connected to the drive motor.

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a material roll-off prevention device for an inclined shaft belt conveyor. It employs a buffer baffle to decelerate rolling materials, preventing heavy objects from directly impacting the limiting anti-roll baffle and reducing the likelihood of deformation and damage. A vibration damping component enhances the deceleration effect and provides tiered blocking, ensuring that only relatively heavy objects can pass through the buffer baffle and be intercepted at the limiting anti-roll baffle, thus reducing the working pressure on the limiting anti-roll baffle. A V-frame guides the rolling materials, causing them to move towards the center from the edge of the conveyor, preventing them from falling from either side of the conveyor.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] This utility model discloses a material roll-off prevention device for belt conveyors in inclined shafts.

[0025] Example 1:

[0026] Reference Figure 1An anti-material roll-off device for an inclined shaft belt conveyor is disclosed. The anti-material roll-off device is installed on the supports on both sides of the belt conveyor 6 and includes a frame 1, a buffer baffle 2, and a limiting anti-roll baffle 3. The frame 1 is a hollow box structure welded from 5mm steel plates and channel steel. The frame 1 includes a top plate 12 and side plates 11 vertically welded and fixed to both sides of the top plate 12. The bottom end of the side plates 11 away from the top plate 12 is connected to the support of the belt conveyor 6.

[0027] Reference Figure 1 Both the anti-roll baffle 3 and the buffer baffle 2 are hinged to the bottom surface of the top plate 12, and the anti-roll baffle 3 and the buffer baffle 2 are arranged sequentially along the conveying direction of the belt conveyor 6; the anti-roll baffle 3 is provided with a limiting plate 121 on the side away from the buffer baffle 2, the limiting plate 121 is fixed to the bottom surface of the top plate 12, and the anti-roll baffle 3 abuts against the limiting plate 121 when it flips away from the buffer baffle 2; the buffer baffle 2 can swing back and forth along the conveying direction of the belt; the buffer baffle 2 includes a connecting plate 21 hinged to the top plate 12 and a main baffle 22 detachably installed on the connecting plate 21; the side wall of the main baffle 22 of the buffer baffle 2 is glued and fixed with a buffer rubber pad.

[0028] In this embodiment, the connecting plate 21 of the buffer baffle 2 is made of 10mm thick steel plate. U-shaped connecting frames 13 are welded and fixed at both ends of the bottom of the side plate 11. When the anti-material rolling device is installed on the support of the belt conveyor 6, the U-shaped connecting frame 13 covers the support of the belt conveyor 6, and a locking screw is passed through the U-shaped connecting frame 13. By tightening the locking screw, it is pressed against the support, thus completing the installation and fixing of the anti-material rolling device.

[0029] When the object rolls downwards, it first collides with the buffer baffle 2, reducing its rolling kinetic energy. The object then rolls through the buffer baffle 2 to the front of the limiting anti-roll baffle 3. Because the limiting anti-roll baffle 3 has a limit plate 121 on one side, it can only swing towards the buffer baffle 2. When the conveyor belt is normally transporting upwards, if a large piece of coal or gangue rolls downwards, its rolling speed is first reduced at the buffer baffle 2, and it is stopped at the limiting anti-roll baffle 3. Since the device has a box-like structure, the object is locked inside the box and cannot roll to either side of the frame, effectively preventing accidents caused by rolling objects. The buffer baffle 2 is used to slow down the object and prevent it from directly impacting the limiting anti-roll baffle 3, reducing the possibility of deformation and damage.

[0030] Example 2:

[0031] Reference Figures 2 to 4The difference between this embodiment and embodiment 1 is that a vibration damping component 4 is provided between the buffer baffle 2 and the top plate 12. The vibration damping component 4 includes an arc-shaped guide rod 41 and a damping spring 42. One end of the arc-shaped guide rod 41 is fixed to the bottom surface of the top plate 12. A slot 211 is provided on the side of the connecting plate 21 near the top plate 12. The arc-shaped guide rod 41 passes through the slot 211 and is inserted into the connecting plate 21. The damping spring 42 is sleeved on the outside of the arc-shaped guide rod 41. One end of the damping spring 42 is fixedly connected to the bottom surface of the top plate 12, and the other end is fixedly connected to the side wall of the connecting plate 21. When the falling object collides with the buffer baffle 2, the connecting plate 21 applies pressure to the damping spring 42, causing the damping spring 42 to compress. When the weight and potential energy of the falling object are large, it can break through the obstruction of the buffer baffle 2 and roll to the limiting anti-roll baffle 3. Then, the setting of the vibration damping component 4 can improve the deceleration effect of the falling object on the one hand, and play a graded blocking role for the falling object on the other hand. Only the falling object with relatively large weight can roll through the buffer baffle 2 to the limiting anti-roll baffle 3 and be intercepted, thereby reducing the working pressure of the limiting anti-roll baffle 3 in intercepting and preventing falling.

[0032] Reference Figures 2 to 4 A traction deceleration mechanism 5 is provided on the side wall of the buffer baffle 2 away from the limiting anti-roll baffle 3. The traction deceleration mechanism 5 is slidably connected to the buffer baffle 2. The traction deceleration mechanism 5 includes a crossbeam 52 and a V-frame 51. The V-frame 51 includes connecting rods 511 connected at both ends. The opening of the V-frame 51 faces away from the buffer baffle 2. The V-frame 51 is mounted on the crossbeam 52, which can slide along the height direction of the buffer baffle 2. The V-frame 51 guides the rolling objects, causing the rolling objects that have moved to the edge of the belt conveyor 6 to move towards the center under the guidance of the V-frame 51, preventing the rolling objects from falling from both sides of the belt conveyor 6.

[0033] Reference Figures 2 to 4 A slider is fixed on the crossbeam 52, and a groove 221 adapted to the slider is provided on the main baffle. The slider is slidably connected to the inner wall of the groove 221. The A-frame 51 is slidably connected to the buffer baffle 2 via the crossbeam 52. When the buffer baffle 2 flips toward the limiting anti-roll baffle 3, the A-frame 51 slides upward under the action of the contact force with the top wall of the belt conveyor 6, thereby allowing the material to pass through the buffer baffle 2 and preventing interference. In this embodiment, the slider and the groove 221 are configured in pairs to ensure the smoothness of the sliding process.

[0034] The ends of the connecting rods 511 near the buffer baffle 2 are all hinged to the crossbeam 52; a buffer spring 53 is provided between each connecting rod 511 of the A-frame 51 and the crossbeam 52, with one end of the buffer spring 53 fixedly connected to the connecting rod 511 and the other end fixedly connected to the crossbeam 52. The buffer spring 53 reduces the impact of rolling objects on the A-frame 51, providing a buffering and protective function.

[0035] Reference Figures 2 to 4 A limiting block 15 is provided at the bottom end of the side of the anti-roll baffle 3 away from the buffer baffle 2. A rotating shaft is fixed on the limiting block 15. An end plate 111 is welded to the side of the side plate 11 near the limiting roll baffle 3. The rotating shaft passes through the end plate 111, and one end of the rotating shaft is connected to a drive motor 14. The drive motor 14 is fixed to the end plate 111 by bolts. A pressure sensor is provided on the connecting rod 511, and the pressure sensor is electrically connected to the drive motor 14. When the pressure sensor detects that the buffer baffle 2 is impacted by rolling objects, it transmits a signal to the drive motor 14. The drive motor 14 drives the limiting block 15 to deflect toward the limiting roll baffle 3, thereby limiting the bottom side of the limiting roll baffle 3. The bottom limiting block 15 cooperates with the top limiting plate 121 to improve the interception effect of the limiting roll baffle 3 on rolling objects, reduce the torque on the limiting roll baffle 3, and improve impact resistance.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
