Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, in particular to a long-distance belt conveyor protection device. Background Art

[0002] As a commonly used material conveying equipment, belt conveyors are widely used in material transportation. Long-distance belt conveyors are especially suitable for the transportation of bulk materials, with the characteristics of long transportation distance, large transportation volume, and continuous transportation. However, with the increase of transportation distance and material load, especially for materials with a high center of gravity, belt conveyors are prone to deviation and fall during operation.

[0003] Traditional belt conveyors often lack effective anti-deviation devices and cannot correct the deviation of the conveyor belt in time. This causes the conveyor belt to easily deviate from the track or even fall during operation, seriously affecting its safety and stability. As the conveying length increases, the risk of material falling also increases. Therefore, a new type of long-distance belt conveyor protection device is urgently needed to provide an effective solution to the defects of the existing technology. Summary of the invention

[0004] The object of the present invention is to provide a long-distance belt conveyor protection device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A long-distance belt conveyor protection device comprises a pair of follow-up correcting devices, the follow-up correcting devices are symmetrically installed on the frames on both sides of the long-distance belt conveyor, the follow-up correcting devices comprise an upper wheel disc, a lower wheel disc and a wheel disc frame with the same shape and structure, the upper wheel disc and the lower wheel disc are fixedly connected by a disc column, a group of rollers are rotatably installed between the upper wheel disc and the lower wheel disc, the roller annular array is distributed on the outside of the outer edges of the upper and lower wheel discs, the upper and lower ends of the roller axles are slidably installed on the outer edges of the upper and lower wheel discs through a telescopic buffer mechanism, the wheel disc frame is fixedly installed on the outer side wall of the long-distance belt conveyor frame, a main shaft is fixedly installed at the center position of the bottom of the lower wheel disc, the main shaft is rotatably installed at the center position of the wheel disc frame platform, a driving motor and a transmission box are installed below the wheel disc frame platform, and the main shaft is driven to rotate by the driving motor.

[0006] Furthermore, the telescopic buffer mechanism includes a guide column, and guide holes and avoidance grooves are distributed in a ring array on the outer edges of the upper and lower wheel discs, the avoidance grooves are located on the inner sides of the guide holes, and the guide holes penetrate the avoidance grooves and the circumferential outer walls of the upper and lower wheel discs. The guide column is slidably installed in the guide holes, and the two ends of the guide column are respectively fixedly connected to a limit seat and an axle seat, the limit seat is located in the avoidance groove, and the axle seat is located on the outer side of the upper and lower wheel discs, and the roller is rotatably installed between the axle seats on the upper and lower sides, and a spring is sleeved on the guide column, and the two ends of the spring respectively abut against the circumferential outer surface of the upper and lower wheel discs and the axle seat.

[0007] Furthermore, a rubber layer is provided on the circumferential outer surface of the rotating roller, and resistance-enhancing structures are densely distributed on the rubber surface.

[0008] Compared with the prior art, the present invention has the following beneficial effects: When the motor of the present invention is started, the main shaft will drive the entire follow-up deviation correction device to rotate, and a pair of symmetrical follow-up deviation correction devices will rotate synchronously in opposite directions, and the rollers will clamp and guide the material to move to the center of the conveyor belt. Guide holes and avoidance grooves are distributed in an annular array on the outer edges of the upper and lower wheel discs, and the guide holes pass through the avoidance grooves and are connected to the circumferential outer walls of the wheel discs. The guide post is slidably installed in the guide hole, and its two ends are respectively connected to the limit seat and the shaft seat. The spring sleeve is arranged on the guide post, and its two ends are respectively against the circumferential outer surface of the wheel disc and the shaft seat. When the roller is subjected to the pressure of the conveyor belt or the material, the shaft seat will drive the guide post to slide in the guide hole and compress the spring at the same time. The elastic force of the spring plays a buffering role, which can absorb and disperse the impact force on the roller, thereby protecting the conveyor belt and the material from damage.

[0009] In the present invention, a rubber layer is provided on the circumferential outer surface of the rotating roller, which can increase the friction between the rotating roller and the material, so that the rotating roller can better clamp and guide the material on the conveyor belt.

[0016] A rubber layer is provided on the circumferential outer surface of the rotating roller 10 , and resistance-enhancing structures are densely distributed on the rubber surface.

[0017] Working principle of this embodiment: The follow-up deviation correction device 3 is mainly composed of a wheel disc frame 4 and an upper wheel disc 9 and a lower wheel disc 8 of the same shape and structure. The upper wheel disc 9 and the lower wheel disc 8 are fixedly connected by a disc column 17 to form a stable frame. On the outer edge of this frame, a group of rollers 10 are distributed in a circular array. These rollers 10 are installed on the upper wheel disc 9 and the lower wheel disc 8 through a telescopic buffer mechanism, and can perform a certain range of telescopic movement in the horizontal plane. The telescopic buffer mechanism is mainly composed of a guide column 12, a guide hole 15, an air avoidance groove 16, a limit seat 14, an axle seat 11 and a spring 13. Guide holes 15 and air avoidance grooves 16 are distributed in a circular array on the outer edge of the upper wheel disc 9 and the lower wheel disc 8.
