Description

Technical Field

[0001] This utility model belongs to the field of transport machinery technology, and in particular relates to an anti-deviation auxiliary mechanism for an underground belt conveyor in mining construction. Background Technology

[0002] In mining operations such as underground excavation and tunneling, belt conveyors are widely used as core material handling equipment, playing an irreplaceable role in ensuring the continuity of mining operations, improving material transfer efficiency, and reducing manual labor intensity. With the increasing depth and scale of mineral resource extraction, the underground working environment is becoming increasingly complex, and the types of materials to be transported are becoming more diverse, ranging from fine coal powder to lumpy ore. This places higher demands on the operational stability and anti-deviation capabilities of belt conveyors. During operation, it is often necessary to ensure that belt conveyors maintain stable operation under long-term heavy loads, bumps, and vibrations to prevent belt deviation from causing material spillage, equipment wear, or even shutdown accidents. However, traditional anti-deviation mechanisms are mostly rigid structures fixed by welding or a single bolt, with rudimentary adjustment designs and a lack of precise fine-tuning components. They cannot adapt to belts of different widths and thicknesses, nor can they be precisely adjusted according to the characteristics of the transported materials and changes in belt tension. Their adaptability is severely insufficient, thus failing to reliably guarantee the anti-deviation effect, necessitating improvement. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-deviation auxiliary mechanism for underground belt conveyors in mining construction, aiming to solve the technical problem of an anti-deviation auxiliary mechanism for underground belt conveyors in mining construction in the prior art.

[0004] To achieve the above objectives, this utility model provides an anti-deviation auxiliary mechanism for an underground belt conveyor in mining construction, comprising a body, an internally rotatably connected drive shaft, a conveyor belt attached to the surface of the drive shaft, rollers on the inner surface of the conveyor belt, a fixed shaft rotatably connected to one side of the rollers, an arc-shaped plate sleeved on the surface of the fixed shaft, a spring fixedly installed on one side of the arc-shaped plate, a baffle fixedly installed on one side of the spring, a nut fixedly installed at the bottom of the baffle, a double-ended lead screw threaded internally connected to the nut, a handwheel A fixedly installed at one end of the double-ended lead screw, an auxiliary frame fixedly installed on one side of the fixed shaft, an adjusting frame fixedly installed at the bottom of the auxiliary frame, an adjusting lead screw threaded internally connected to the adjusting frame, and a handwheel B fixedly installed at one end of the adjusting lead screw.

[0005] Optionally, auxiliary wheels are slidably connected to the inner surface of the adjusting frame, and the number of auxiliary wheels is multiple sets arranged in an array. Here, by setting slidably connected auxiliary wheels, in conjunction with the linkage between the adjusting frame and the adjusting screw, precise fine-tuning of the position of the auxiliary wheels can be achieved. This allows for the adaptation to various specifications of conveyor belts with different widths and thicknesses, solving the problem that traditional mechanisms cannot adapt to multiple belt specifications. At the same time, it improves the support and guiding stability of the conveyor belt and ensures the anti-deviation effect.

[0006] Optionally, the spring is sleeved on the surface of the fixed shaft, and the inner surface of the baffle is slidably connected to the surface of the fixed shaft. Here, the design of the spring and the sliding baffle replaces the traditional rigid connection structure. It not only plays a buffering and protective role when the conveyor belt deviates, but also adapts to different material characteristics and belt tension fluctuations by adjusting the spring preload. This solves the problem of the traditional mechanism being simple to adjust and unable to make targeted and precise adjustments, thus improving the adaptability of the mechanism.

[0007] Optionally, the surface of the auxiliary frame is slidably connected to the inner surface of the machine body, and one end of the adjusting screw is rotatably connected to the bottom surface of the machine body. Here, the sliding engagement between the auxiliary frame and the machine body, combined with the drive of the adjusting screw, can drive the entire anti-deviation assembly to make fine adjustments to its position, further improving the flexibility and accuracy of the mechanism adjustment. This allows for better adaptation to the anti-deviation requirements under different working conditions and overcomes the inconvenience of traditional mechanism adjustments.

[0008] Optionally, a support frame is fixedly installed at the bottom of the machine body, a tension spring is fixedly installed inside the support frame, a connecting block is fixedly installed at one end of the tension spring, a pulley is fixedly installed at the bottom of the connecting block, and a pedal is slidably connected to one side of the connecting block. Here, the linkage design of the pulley, tension spring, and pedal allows the mechanism to be moved easily, solving the problem of immobility and facilitating rapid relocation of the mechanism according to downhole operation needs, thus improving operational convenience.

[0009] Optionally, an L-shaped groove is provided on one side of the support frame, and the surface of the connecting block is slidably connected to the inner surface of the support frame. Here, the L-shaped groove can realize the locking and fixing of the pedal, ensuring that the pulley is stably grounded when the mechanism moves. After the locking is released, the tension spring can drive the pulley to quickly return to its original position, so that the support frame can provide stable support. This further optimizes the movement and fixing functions of the mechanism and avoids the problems of cumbersome, time-consuming and laborious movement of traditional fixing mechanisms.

[0010] The above-mentioned technical solutions of one or more of the above-mentioned technical solutions in the anti-deviation auxiliary mechanism of the underground belt conveyor provided in this utility model embodiment have at least one of the following technical effects: 1. In this utility model, by setting up components such as a machine body, drive shaft, conveyor belt, rollers, fixed shaft and arc plate, the position and buffering force of the arc plate can be flexibly adjusted by the linkage of handwheel A with double lead screw and nut, and with the help of sliding baffle and spring. At the same time, the adjustment lead screw driven by handwheel B drives the adjustment frame and auxiliary wheel to move, which can adapt to belts of different specifications. This replaces the traditional rigid fixed structure, fills the shortcomings of the traditional mechanism adjustment, and can make precise adjustments according to the material characteristics and belt tension changes, continuously and stably limiting and guiding the belt to avoid belt deviation affecting the operation.

[0011] 2. In this utility model, by setting up a support frame, tension spring, connecting block, pulley and pedal, the linkage between the pedal and the connecting block, combined with the cooperation between the tension spring and the pulley, can quickly complete the movement and fixation of the mechanism, replacing the traditional welding fixation method, solving the problem that the traditional mechanism cannot move flexibly, and can quickly adjust the working position of the mechanism according to the actual needs of downhole operations. At the same time, with the adjustment structure of the anti-deviation component, the overall adaptability is further improved. Attached Figure Description

[0018] In one embodiment of this utility model, such as Figures 1-5As shown, an anti-deviation auxiliary mechanism for an underground belt conveyor in mining construction is provided, including a body 1. An active shaft 2 is rotatably connected inside the body 1, driving a conveyor belt 3 to operate stably and providing the power basis for material conveying. The surface of the active shaft 2 is fitted with the conveyor belt 3, enabling continuous material conveying and solving the problem of low efficiency in traditional conveying methods.

The surface of the fixed shaft 5 is fitted with... An arc-shaped plate 6 is provided, which can apply a reverse guiding force to the misaligned belt using its own curvature to correct the misalignment. A spring 7 is fixedly installed on one side of the arc-shaped plate 6 to act as a buffer and prevent the belt from colliding hard with the arc-shaped plate 6 and causing wear. A baffle 8 is fixedly installed on one side of the spring 7 to transmit the elastic force of the spring 7 and to achieve adjustment in conjunction with the double-acting screw 10.

The auxiliary wheel 16 is slidably connected to the inner surface of the adjustment frame 13, allowing for close contact with the belt.

[0019] In another embodiment of this utility model, a support frame 17 is fixedly installed at the bottom of the body 1 of the anti-deviation auxiliary mechanism of the underground belt conveyor in mining construction, providing stable support for the entire mechanism and ensuring stability during operation. A tension spring 18 is fixedly installed inside the support frame 17, which can realize the automatic reset of the connecting block 19, simplifying the fixing operation. A connecting block 19 is fixedly installed at one end of the tension spring 18, which can drive the pulley 20 to move synchronously, realizing the switching between movement and fixing. A pulley 20 is fixedly installed at the bottom of the connecting block 19, which makes the mechanism easy to move and solves the problem of traditional mechanisms being unable to move. A pedal 21 is slidably connected to one side of the connecting block 19, which facilitates manual control of the extension and retraction of the pulley 20, making operation convenient.

The surface of the connecting block 19 is slidably connected to the inner surface of the support frame 17, ensuring smooth movement of the connecting block 19 and ensuring reliable switching between movement and fixing functions.

[0020] Working principle: Before the equipment starts operating, handwheel A11 needs to be turned in advance according to the characteristics and weight of the transported materials. This adjusts the initial position of baffle 8 via the double-acting screw 10, thereby changing the initial preload of spring 7. The change in the preload of spring 7 directly adjusts the extension length of arc plate 6. The longer the extension length of arc plate 6, the more severe the potential deviation of the flat belt. Precise adjustment is required to ensure that the anti-deviation mechanism adapts to the current working conditions. Simultaneously, turning handwheel B15 drives the adjusting screw 14 to rotate, which in turn drives the adjusting frame 13 to perform precise positioning adjustments. Adjustment is performed, and the adjustment frame 13 synchronously drives the auxiliary wheel 16 on it to move until the auxiliary wheel 16 is completely in contact with the surface of the conveyor belt 3. During this process, the auxiliary frame 12 will slide with the adjustment frame 13 within the machine body 1, and the anti-deviation components such as the fixed shaft 5 and the arc plate 6 will also synchronously adjust their positions slightly to ensure that the anti-deviation mechanism, the auxiliary wheel 16 after contact, and the conveyor belt 3 maintain a coordinated relative position. If it is necessary to move the entire mechanism, the pedal 21 can be stepped down. The pedal 21 drives the connecting block 19 to move down and synchronously drives the pulley 20 to extend and contact the ground. At this time, the pedal 21 is pushed into the L-shaped groove 22 of the support frame 17. The mechanism is locked, keeping pulley 20 grounded. After the machine body 1 is moved to the designated working position, the pedal 21 is pushed out of the horizontal groove restriction of the L-shaped groove 22. The tension spring 18 returns to its original deformation and pulls the connecting block 19 upward to reset. The pulley 20 retracts, and the support frame 17 contacts the ground to bear the weight of the entire mechanism, completing the mechanism fixation. After the equipment is started, the drive shaft 2 rotates, driving the conveyor belt 3 to run along the preset track through friction. During this process, the auxiliary wheel 16 on the adjusting frame 13 acts as the main support component, fitting against the surface of the conveyor belt 3 to provide core support and guidance. The roller 4 in the anti-deviation mechanism... It is only an auxiliary component of the anti-deviation system. Supported by the fixed shaft 5, it rotates synchronously with the conveyor belt 3 to help maintain the relative position stability between the anti-deviation mechanism and the conveyor belt 3, ensuring the normal triggering of the subsequent anti-deviation function. During the operation of the equipment, if the conveyor belt 3 shows a tendency to deviate, its edge will first contact the arc plate 6 on the fixed shaft 5. At this time, the spring 7 on one side of the arc plate 6 plays a buffering and protective role, avoiding direct hard collision between the conveyor belt 3 and the arc plate 6 to reduce component wear. At the same time, the arc plate 6 applies a reverse guiding force to the conveyor belt 3 with its own curvature, and the buffering effect of the spring 7 quickly corrects the deviation.

[0021] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
