Description

Technical Field

[0001] This utility model belongs to the field of mine conveyor belt technology, and more specifically, relates to a mine conveyor belt structure. Background Technology

[0002] In the mining industry, mining belt conveyors are a widely used material conveying equipment. They mainly consist of a conveyor belt, drive unit, idlers, tensioning device, and other components, and achieve efficient transportation of materials such as ore and coal through the continuous operation of the conveyor belt.

[0003] Mining belt conveyors have several key advantages. First, they have a high conveying capacity, enabling the transport of large quantities of materials in a short time, significantly improving mine production efficiency. Second, they are stable and reliable in operation; after proper design, installation, and commissioning, they can operate continuously for extended periods, minimizing downtime due to equipment failure. Third, they are highly adaptable, allowing for adjustments and layouts based on different mine terrains and working environments.

[0004] Mining conveyor belts require emergency stops under certain circumstances. When the conveyor belt experiences severe misalignment, tearing, or becomes stuck with large foreign objects, it must be stopped immediately to prevent further damage to the equipment. If a malfunction is detected in the drive unit, such as abnormal noise, severe vibration, or overheating, the conveyor belt must also be stopped immediately for repair. Furthermore, in the event of an emergency safety incident, such as personnel injury, stopping the conveyor belt immediately can maximize the safety of personnel.

[0005] If the conveyor belt motor reverses after an emergency stop, it will cause numerous hazards. First, it may cause the conveyor belt to run in reverse, complicating existing faults and increasing the difficulty and cost of maintenance. For example, it may further enlarge tears in the conveyor belt or make it more difficult to remove stuck foreign objects. Second, motor reversal may damage the drive unit and transmission system, affecting the equipment's lifespan. It may also trigger electrical faults such as short circuits and tripping, impacting the entire mine's power system and potentially causing fires and other safety accidents, seriously threatening the safety of personnel and equipment. Furthermore, motor reversal will disrupt the mine's normal production order, causing production stoppages and resulting in economic losses for the company. Utility Model Content

[0006] In view of this, the present invention provides a mining belt structure that can solve the problem of motor reversal after emergency stop of mining belt conveyor, thereby improving the safety of the equipment.

[0007] This utility model is implemented as follows:

[0008] This utility model provides a mine conveyor belt structure, including a motor and a conveyor belt. The motor is fixed to the ground via a fixed end and is rotatably connected to the fixed end. The motor and the fixed end form an inverted U-shape. The conveyor belt is moved by the motor. An anti-reverse mechanism is provided on the motor shaft. The anti-reverse mechanism contacts the motor and is used to prevent the motor from reversing when it stops suddenly.

[0009] Based on the above technical solution, the mine conveyor belt structure of this utility model can be further improved as follows:

[0010] The anti-reverse mechanism includes a fixing mechanism and an anti-rotation mechanism. The fixing mechanism and the anti-rotation mechanism form an inverted U-shape. The fixing mechanism is the two ends of the U-shape and is fixed to the ground. The anti-rotation mechanism is the upper end of the U-shape, and the bottom end contacts one side of the motor. The bottom end of the anti-rotation mechanism is provided with a first protrusion, and the side wall on one side of the motor is provided with a second protrusion corresponding to the teeth at the bottom end of the anti-rotation mechanism.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a fixing mechanism and an anti-rotation mechanism, the motor can be prevented from rotating in the opposite direction by controlling the rotation of the motor sidewall.

[0012] Furthermore, the first protrusion is triangular in shape, with one side of the triangle perpendicular to the top of the anti-rotation mechanism and the extension of the other end intersecting the top of the anti-rotation mechanism; the second protrusion is a triangle with one end coinciding with the side wall radius of the motor and the other end not intersecting the central axis of the motor.

[0013] Furthermore, the end of the second protrusion that does not intersect with the central axis is located on the rear side in the direction of motor rotation.

[0014] Furthermore, the anti-reverse mechanism also includes an anti-reverse gear mechanism, which includes a gear disk, a fixed shaft, and a spring. The fixed shaft is sleeved on the top fixed shaft of the motor and fixedly connected to the fixed end. The gear disk is sleeved on the outside of the fixed shaft and can move on the fixed shaft. The gear disk is disc-shaped, and its axis coincides with the axis of the motor. The gear disk is in contact with the top wall of the motor. A first ratchet is provided on the side of the gear disk near the motor, and a second ratchet adapted to the first ratchet is provided on the side of the motor near the gear disk. The spring is sleeved on the side of the fixed shaft away from the motor.

[0015] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting an anti-reverse gear mechanism, the reverse rotation of the motor is further restricted.

[0016] Furthermore, the first ratchet and the second ratchet are unidirectional ratchets, with the inclined side of the second ratchet located at the front end of the rotation direction of the vertical side.

[0017] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by setting a one-way ratchet, the anti-reverse gear mechanism controls the motor to rotate only in the forward direction. When reversing, the motor cannot rotate due to the control of the one-way ratchet.

[0018] Furthermore, the fixed shaft sidewall is provided with a strip-shaped protrusion along the axial direction, and the inner sidewall of the gear disk is provided with a recess that corresponds to the strip-shaped protrusion.

[0019] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting the strip-shaped protrusion, the gear disk can only move on the fixed shaft and cannot rotate.

[0020] Furthermore, the distance between the anti-rotation mechanism and the motor shaft is greater than 1 / 2 of the radius of the end of the motor that contacts the belt.

[0021] Furthermore, the radius of the gear disk is equal to the radius of the side of the motor that contacts the gear disk.

[0022] Furthermore, a limiting block is provided at the top of the fixed shaft near the motor to limit the position of the gear disk.

[0023] Compared with the prior art, the beneficial effects of the mine conveyor belt structure provided by this utility model are:

[0024] Preventing motor reverse rotation: By setting up an anti-reverse rotation mechanism, including a fixing mechanism, an anti-rotation mechanism, and an anti-reverse rotation gear mechanism, it is ensured that the motor will not reverse in the event of an emergency stop or accident, thereby protecting the safety of the equipment and operators.

[0025] Structural stability: The motor and the fixed end form an inverted U-shaped structure, which increases the stability of the entire system, making the motor more stable during operation and reducing the risk of failure caused by vibration or impact.

[0026] Precise control: The design of the first and second protrusions allows for precise control of the rotation of the motor sidewall, further preventing the motor from rotating in the opposite direction and improving the reliability of the system.

[0027] Enhanced safety: By setting a one-way ratchet, the anti-reverse gear mechanism ensures that the motor can only rotate in the forward direction. Even under a reverse command, the motor will not rotate, thereby avoiding potential equipment damage and safety accidents.

[0028] Restricting gear disk movement: The strip-shaped protrusions on the side wall of the fixed shaft and the recessed design on the inner side wall of the gear disk restrict the movement of the gear disk on the fixed shaft, but do not allow it to rotate, which increases the stability and durability of the system.

[0029] Optimized design: The distance between the anti-rotation mechanism and the motor shaft, as well as the fact that the radius of the gear disk is equal to the radius of the side in contact with the motor, are all designed to optimize the structural design and improve overall performance.

[0030] Limiting design: A limiting block is designed at the top of the fixed shaft near the motor side to limit the position of the gear disk, ensuring that the gear disk works in the correct position and avoiding failures caused by improper positioning.

[0031] Easy maintenance: Due to its reasonable structural design, the fixing and connection of each component is simple, which facilitates daily inspection and maintenance and reduces maintenance costs.

[0032] High adaptability: This structural design is not only suitable for mining environments, but can also be adjusted as needed to adapt to other industrial environments that require belt drives.

[0033] Improve production efficiency: By ensuring stable operation of the motor and preventing accidental reverse rotation, downtime can be reduced, thereby improving production efficiency and economic benefits.

[0034] In summary, this utility model of mine conveyor belt structure improves the safety, stability, and efficiency of mine operations through its unique design. Attached Figure Description
