Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to an anti-deviation multi-directional running device for a belt storage bin in a downhole gate belt. Background Technique

[0002] The downhole gate belt refers to a belt conveyor system used in underground mines or coal mining scenarios. The belt is usually designed to run along the direction of coal mining. The downhole gate belt storage bin is a warehouse facility used to store, accumulate and manage coal or other materials conveyed from the downhole gate belt conveyor.

[0003] During the use of the conveyor belt, the distribution of materials on the belt is uneven, or the accumulation of materials is uneven, resulting in an unbalanced lateral force, causing the belt to deviate, increasing the wear of the local conveyor belt, and reducing the service life of the conveyor belt. For this reason, we propose an anti-deviation multi-directional running device for a downhole gate belt storage bin to solve the existing problems. Content of the Utility Model

[0004] The purpose of the utility model is to propose an anti-deviation multi-directional running device for a downhole gate belt storage bin aiming at the problems existing in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-deviation multi-directional running device for a downhole gate belt storage bin, including a frame, a base, a bottom plate, a mounting plate and a first motor. A conveying roller is rotatably installed inside the frame, and the output end of the first motor is connected to one end of the conveying roller. Hydraulic rods I are arranged at both the front and rear ends of the frame. The upper ends of the hydraulic rods I are provided with mounting plates. Rotating shafts evenly distributed are rotatably installed inside the opposite ends of the mounting plates. Guide rollers are arranged at one ends of the rotating shafts and are located on the inner wall of the upper end of the conveyor belt. Two groups of evenly distributed displacement sensors are arranged at the upper end of the frame, and a base is arranged at the lower end of the frame.

[0006] When using the anti-deviation multi-directional running device for a downhole gate belt storage bin in this solution, the first motor drives the conveying roller to rotate, driving the conveyor belt to rotate on the outer wall of the conveying roller, and the guide rollers roll and support the side of the conveyor belt. When the conveyor belt deviates, the displacement sensors detect the conveyor belt, and the detection signal is transmitted to the terminal. The hydraulic rod I is controlled by the terminal to lift, and the hydraulic rod drives the mounting plate to lift, so that the height of the guide rollers is lifted. The height of one side of the conveyor belt is lifted by the guide rollers. A resistance is applied to one side of the conveyor belt through the conical surface on the outer wall of the guide roller to prevent further deviation of the conveyor belt, and the conveyor belt is pushed towards the center of the box, thereby correcting the conveyor belt;

[0007] During the use of the conveyor belt, the second motor operates to drive the brush roller to rotate, driving the brush to rotate and contact the conveyor belt. The materials adhered to the conveyor belt are brushed off and diverted through the two sides of the inclined surface box base;

[0008] The motor three operates to drive the base to rotate. The base rotates inside the guide rail through pulleys, and the bottom side of the base is supported by rolling, driving the base to rotate. The rack and the conveyor belt can be adjusted for multi-directional conveying. At the same time, the hydraulic rod three drives the stroke plate to move horizontally. The stroke plate slides inside the chute through a slider, thereby enabling a small stroke adjustment of the horizontal position between the stroke plate and the conveyor belt above.

[0009] Preferably, conical sleeves are sleeved on the outer walls of the front and rear ends of the conveying roller, and the outer diameters of the conical sleeves gradually decrease towards the center of the conveying roller. The conveying roller applies resistance to the front and rear ends of the conveyor belt through the conical sleeves. When the belt deviates, the conveyor belt is subjected to resistance, playing a role in suppressing the deviation of the conveyor belt.

[0010] Preferably, the outer wall of the guide roller is a conical surface, and the radius of the outer wall of the guide roller gradually decreases from the outside to the inside. The conical surface of the guide rail applies resistance to the front and rear ends of the conveyor belt. When the belt deviates, the conveyor belt is subjected to resistance, playing a role in suppressing the deviation of the conveyor belt.

[0011] Preferably, sliding sleeves are symmetrically arranged at the front and rear ends of the rack, guide rods are symmetrically arranged at the lower ends of the mounting plates, and the lower ends of the guide rods are slidably installed inside the sliding sleeves. When the mounting plate moves longitudinally, the guide rods slide inside the sliding sleeves, thereby guiding the sliding of the mounting plate during longitudinal movement.

[0012] Preferably, a motor two is arranged at the front end of the base. The output end of the motor two is provided with a brush roller rotatably installed inside the base. A plurality of groups of brushes arranged in a circular array are provided on the outer wall of the brush roller, and inclined surfaces are symmetrically arranged on the inner wall of the lower end of the base. When the motor two operates, it drives the brush roller to rotate, causing the brushes to rotate and contact the conveyor belt. Because of the symmetrical distribution of the inclined surfaces, the materials brushed off by the brushes can flow to both sides of the base through the inclined surfaces, avoiding material accumulation inside the base.

[0013] Preferably, a bottom plate is arranged below the base. A stroke plate is arranged at the upper end of the bottom plate, and a motor three is arranged at the upper end of the stroke plate. The upper end of the motor three is connected to the base. When the motor three operates, it drives the base to rotate, thereby driving the rack and the conveyor belt to rotate, and the conveying angle of the materials is adjusted.

[0014] Preferably, pulleys arranged in a circular array are provided at the lower end of the base, and a circular guide rail is formed inside the upper end of the stroke plate. The pulleys are rotatably installed inside the guide rail. The base slides inside the guide rail through the pulleys arranged in a circular array, providing multi-point rolling support for the bottom of the base and reducing the pressure on the output shaft of the motor three.

[0015] Preferably, symmetrically distributed sliders are provided at the lower end of the stroke plate. A chute is provided inside the upper end of the bottom plate. The sliders are slidably installed inside the chute. A hydraulic rod two with a telescopic end connected to the stroke plate is provided at the upper end of the bottom plate. The stroke plate slides inside the chute through the sliders, providing sliding support for the bottom of the stroke plate and guiding the sliding of the stroke plate.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, the conveyor roller is driven to rotate by the first motor, driving the conveyor belt to rotate. The material is transported along with the conveying direction of the belt, and then the coal mined underground is transported to the warehouse equipment along the direction of coal mine mining. The displacement sensor detects whether the belt is offset. When the belt is offset, the first hydraulic rod drives the mounting plate to lift, driving the guide roller to lift one side of the lower end of the belt and pushing the belt back to its original position, timely correcting the deviation of the belt running off track and avoiding the situation of reducing the service life of the belt due to deviation.
