Technical Field

[0001] This utility model relates to the field of conveyor technology, and more specifically, to a sidewall belt conveyor alignment device. Background Technology

[0002] With the rapid development and utilization of underground space, Z-shaped, large-angle sidewall hoists are increasingly widely used in engineering construction for lifting mud or excavated soil. Compared to traditional bucket methods and mud removal methods, vertical lifting sidewall belt conveyors have significant advantages in continuous excavation of ultra-deep vertical shafts. However, the installation of vertical lifting sidewall belt conveyors in ultra-deep vertical shafts is relatively difficult, and the installation accuracy is hard to guarantee, often resulting in conveyor belt deviation. Existing adjustment methods can achieve some results in sidewall hoists in vertical shafts with small height differences, but the adjustment process is time-consuming, labor-intensive, and requires multiple people to cooperate. For deep shaft vertical lifting sidewall belt conveyors, there is still a lack of effective technical means for adjustment. Summary of the Invention

[0027] Figure 1 The schematic diagram illustrates a specific structural diagram of an embodiment of the sidewall belt conveyor alignment device of this utility model.

[0028] from Figure 1 As can be seen from the figure, the sidewall belt conveyor alignment device of this embodiment includes a support frame 1, a lead screw 3, a sliding platform 4, and two pulleys 6.

[0029] In this embodiment, the support frame 1 provides stable support for the alignment device. The bottom of the support frame 1 is specially designed with a slot 9 structure for convenient connection with the sidewall belt conveyor. The size and shape of the slot 9 match the connecting components on the belt conveyor, allowing the support frame 1 to fit tightly with the corresponding structure of the conveyor, enabling rapid installation and fixation. This slot connection method not only improves installation efficiency and shortens installation time but also enhances the connection strength and stability between the support frame 1 and the conveyor. During the operation of the alignment device, the support frame 1 remains firmly fixed to the conveyor, preventing displacement or detachment, thus ensuring the stable operation of the alignment device and the normal operation of the conveyor.

[0030] The end cap 2 is fixed with bolts 8. The end cap 2 is tightly secured to both ends of the support frame 1 by multiple bolts 8. The tightening force of the bolts 8 ensures a firm and reliable connection between the end cap 2 and the support frame 1, preventing loosening or detachment due to conveyor vibration or the operation of the alignment device. This bolt 8 connection method also offers the advantage of easy disassembly. When maintenance or replacement of internal components of the alignment device is required, workers can easily remove the end cap 2 from the support frame 1 by simply loosening the bolts 8 using a wrench or similar tools. This greatly facilitates the maintenance of internal components, significantly improves maintenance efficiency, and reduces maintenance costs.

[0031] The main function of end cap 2 is to seal the internal space of support frame 1. In the operating environment of a sidewall belt conveyor, there are often large amounts of dust, impurities, and moisture. If these external factors enter the support frame 1, they will adversely affect key components such as the lead screw 3 and the sliding platform 4. Dust may adhere to the surface of the lead screw 3, increasing its wear and reducing its transmission accuracy; impurities may get stuck in the slide rails of the sliding platform 4, affecting its smooth movement; and moisture may cause corrosion of components, shortening their service life. The sealing function of end cap 2 acts like a strong defense, blocking these adverse external factors from entering the support frame. It fits tightly against the end of the support frame 1, forming a sealed barrier that effectively prevents dust, impurities, and moisture from entering the support frame 1.

[0032] Through the sealing effect of the end cap 2, the lead screw 3 and the sliding platform 4 can operate in a relatively clean and dry working environment. In such an environment, the transmission of the lead screw 3 is more stable and precise, and the movement of the sliding platform 4 is smoother and more flexible, thus greatly extending the service life of the lead screw 3 and the sliding platform 4. At the same time, this also ensures the normal operation of the alignment device, enabling it to continuously and stably perform its alignment function, ensuring that the conveyor belt always stays on the correct running track, avoiding problems such as material spillage and equipment damage caused by conveyor belt deviation, thereby ensuring the efficient and stable operation of the conveyor, and improving production efficiency and economic benefits.

[0033] To better support the lead screw 1 and ensure its smooth passage through the end caps 2, the end caps 2 on both sides are designed with through holes matching the diameter of the lead screw 3. One end of the lead screw 3 can pass smoothly through this through hole, while the end caps 2 effectively support the lead screw 3, keeping it stable during operation. This design not only helps improve the load-bearing capacity and stability of the lead screw 3, but also helps reduce vibration and wear that may occur during the movement of the lead screw 3, thereby further improving the overall performance and reliability of the alignment device.

[0034] Because the through hole of the end cap 2 matches the diameter of the lead screw 3, the lead screw 3 can be well guided and constrained during movement, avoiding unnecessary friction and collision between the lead screw 3 and the end cap 2, thereby reducing the wear of the lead screw 3. At the same time, the stable support also reduces the vibration amplitude of the lead screw 3 during operation, further reducing the risk of fatigue damage caused by vibration and extending the service life of the lead screw 3.

[0035] Through the careful design of the end cap through-hole and the cooperation of the lead screw 3, the overall performance of the belt alignment device is significantly improved. The stable operation of the lead screw 3 ensures that the belt alignment device can accurately and efficiently adjust the conveyor belt, improving the operating efficiency and reliability of the conveyor. At the same time, it reduces the wear and vibration of the lead screw 3, thereby reducing the maintenance cost and failure rate of the belt alignment device, providing a strong guarantee for the long-term stable operation of the conveyor, enabling it to maintain a good working condition under various operating conditions, and safeguarding the smooth progress of the production process.

[0036] The sliding platform 4, located above the lead screw 3, is responsible for supporting and moving other components in the adjustment device. To connect with the lead screw 3, a trapezoidal nut is positioned below the sliding platform 4. The internal thread of this trapezoidal nut precisely matches the external thread on the lead screw surface. When the lead screw 3 begins to rotate under external force, the trapezoidal nut moves accordingly along the axial direction of the lead screw 3 based on its rotation direction and pitch. The moving speed of the trapezoidal nut is determined by the rotation speed and pitch of the lead screw 3.

[0037] Because the trapezoidal nut is fixedly connected to the sliding platform 4, the axial movement of the trapezoidal nut directly drives the sliding platform 4 to achieve precise linear motion. This design allows the sliding platform 4 to quickly and accurately adjust its position according to the conveyor belt's deviation. Whether it's a small adjustment or a large displacement, the sliding platform can easily achieve this under the drive of the lead screw 3, thus ensuring that the belt adjustment device can adjust the conveyor belt in a timely and effective manner, keeping the conveyor belt always on the correct running trajectory.

[0038] This ingenious design not only improves the efficiency of the alignment device but also enhances its alignment accuracy and reliability. The sliding platform 4 can flexibly adjust its position according to different working conditions and alignment requirements, providing strong support for the normal operation of the alignment device. At the same time, this precise linear motion design also helps extend the service life of the alignment device, as it reduces the risk of component wear and failure due to improper positioning. Through this design, the alignment device can maintain a highly efficient and stable working state under various complex working conditions, safeguarding the stable operation of the conveyor, ensuring smooth material transport, and improving production efficiency and economic benefits.

[0039] In such Figure 1 In the illustrated embodiment, the pulley base 5 is mounted on both ends of the sliding platform 4 using bolts 8. The installation position of the pulley base 5 is determined based on the transverse width of the conveyor belt of the sidewall belt conveyor. The pulley base 5 needs to be appropriately adjusted according to the width of the conveyor belt to ensure that the pulley can effectively support and guide the conveyor belt. By properly installing the pulley base 5, the stability and reliability of the conveyor belt during operation can be guaranteed, thereby improving the performance and efficiency of the entire conveying system.

[0040] The pulley base 5 is installed using bolts 8, a method that is both stable and easy to adjust. Specifically, the pulley base 5 is precisely installed at both ends of the sliding platform 4 using multiple bolts 8. The tightening of the bolts 8 ensures a tight and secure connection between the pulley base 5 and the sliding platform 4. Even under vibration and impact generated during conveyor operation, the pulley base 5 will not loosen or shift, thus guaranteeing the stability and reliability of the pulley base 5 and improving the reliability and durability of the entire conveying system.

[0041] To accommodate conveyor belts of varying transverse widths, the pulley base 5 needs to be adjustable. In this embodiment, the installation position of the pulley base 5 can be adjusted by changing the installation position of the bolt 8. During operation, technicians first need to accurately measure the width of the conveyor belt and, based on the measured data, determine the optimal installation point of the bolt 8 in the reserved mounting holes. When the bolt 8 is installed in different positions, the pulley base 5 will move accordingly. By properly installing and adjusting the pulley base 5, it can be ensured that the pulley 6 is always in the appropriate position on the conveyor belt, providing good support and guidance for the conveyor belt.

[0042] During operation, the pulleys 6 on the pulley base 5 maintain stable contact with the conveyor belt, effectively reducing lateral swaying and longitudinal slippage, thus ensuring the stability and reliability of the conveyor belt during operation. This stability not only helps extend the service life of the conveyor belt and reduce downtime for maintenance due to belt damage, but also ensures smooth material transport, preventing material spillage and improving the overall performance and efficiency of the conveying system.

[0043] In other embodiments, the sliding platform 4 can be designed with multiple slots arranged in a row, providing various options for the installation of the pulley base 5. By passing bolts 8 through the pulley base 5 and the corresponding slots, the user can flexibly adjust the position of the pulley base 5 on the sliding platform 4 according to actual needs. This slot design not only improves the adaptability of the conveyor but also enhances its practicality in different application scenarios. Specifically, when the width of the conveyor belt changes, the user can quickly adjust the position of the pulley base 5 to ensure that the pulley 6 is always in a suitable position on both sides of the conveyor belt, thereby providing good support and guidance for the stable operation of the conveyor belt. This flexibility allows the conveyor to adapt to conveyor belts of different widths, reducing downtime caused by equipment adjustments. In addition, the slot design also facilitates the maintenance and upgrading of the conveyor, as the disassembly and reinstallation of the pulley base 5 becomes simpler and faster. In summary, this slotted sliding platform design improves the adaptability and flexibility of the conveyor and enhances its practicality in different application scenarios.

[0044] A pulley 6 is mounted at each end of the pulley base 5. Each pulley 6 includes a pressure plate 7, a wheel body, an axle, a bearing, and a nut. The axle is inserted into the center of the wheel body, providing support for its rotation. The bearing is installed between the wheel body and the axle to reduce friction and ensure smooth and efficient rotation of the wheel body. The nut secures the pulley 6 to the pulley base 5, ensuring its stability and reliability. The pressure plate 7, mounted on both sides of the wheel body, fixes the wheel body to the axle, preventing displacement or detachment during operation. The pressure plate 7 is typically made of a sturdy material to withstand the pressure and friction generated by the wheel body during operation.

[0045] A vertical plate is supported between the pressure plates 7 on both sides of the pulley 6. The main function of the vertical plate is to provide additional support and stability for the pulley 6, ensuring that it can withstand large loads and maintain smooth operation during operation.

[0046] During the operation of the conveyor belt, the wheel needs to maintain close contact with the conveyor belt and be able to withstand the lateral and longitudinal forces exerted by the conveyor belt. Without the fixing effect of the pressure plate 7, the wheel may wobble under these forces or even fall off the shaft, causing the conveyor belt to run off-center or be damaged, thus affecting the normal operation of the conveyor.

[0047] To ensure that the pressure plate 7 effectively fulfills its fixing function, it is typically made of strong and wear-resistant materials. These materials not only possess sufficient strength to withstand the pressure generated by the wheel during operation but also resist wear caused by long-term friction. For example, the pressure plate 7 may be made of high-strength alloy steel or wear-resistant engineering plastics. This material selection allows the pressure plate 7 to maintain its performance over long periods in harsh working environments, providing stable support for the wheel.

[0048] The nut is used to fix the entire pulley 6 to the pulley base 5. By tightening the nut, the shaft, wheel body, pressure plate 7, and other components can be tightly fixed together, and the entire pulley 6 can be firmly installed on the pulley base 5. The tightening force of the nut needs to be moderate, ensuring that the pulley 6 will not loosen during the operation of the conveyor, while avoiding damage to the components due to overtightening.

[0049] The wheel body is the core component of pulley 6. In this embodiment, the wheel body is made of nylon material, which has good wear resistance and self-lubricating properties, effectively reducing friction between the pulley and the rope, thereby extending the service life of the pulley. The surface of the wheel body is usually polished to improve its smoothness and aesthetics.

[0050] The conveyor belt is the main component of a belt conveyor, responsible for transporting materials. Its skeleton material typically consists of polyester-cotton impregnated canvas, steel cord, or metal mesh. The performance of the base belt significantly impacts the overall performance of the sidewall belt conveyor.

[0051] Sidewalls are a key component of conveyor belts, primarily preventing material from slipping off the edges. Sidewalls are typically designed with a corrugated shape to allow the upper part of the sidewall to extend or compress freely when the conveyor belt wraps around rollers or concave / convex sections. To enhance the flexural strength and tear resistance of the sidewalls, the rubber content is usually increased, and nylon fabric is typically added internally as a reinforcing layer.

[0052] When operating on vertical transport sections, the conveyor belt may deviate due to uneven material distribution, insufficient belt tension, or misalignment between the drive and driven rollers. When the deviation reaches a certain extent, the conveyor belt's edge may come into contact with the pulley of the alignment device. This contact can lead to further wear on the conveyor belt and even cause malfunctions. Therefore, it is necessary to adjust the conveyor belt's running direction promptly to return it to the correct running track.

[0053] To achieve this goal, conveyor systems are typically equipped with a deviation adjustment device. In this embodiment, the core components of the deviation adjustment device are the lead screw 3 and the sliding platform 4. By rotating the lead screw 3, the sliding platform 4 can be moved. The movement of the sliding platform 4 realizes the synchronous horizontal movement adjustment of the pulleys 6 on both sides of the conveyor belt. This synchronous horizontal movement adjustment method can effectively adjust the running direction of the conveyor belt, bringing it back to the correct running trajectory, thereby avoiding malfunctions caused by conveyor belt deviation and ensuring the stable operation of the conveyor system.

[0054] This synchronous horizontal movement adjustment method has significant advantages. First, it ensures that the pulleys 6 on both sides of the conveyor belt move simultaneously, avoiding uneven force on the conveyor belt caused by unilateral adjustment. Second, by precisely controlling the rotation angle of the lead screw 3, fine adjustments can be made to the running direction of the conveyor belt, bringing it back to the correct running trajectory. This adjustment method not only effectively corrects conveyor belt deviation but also reduces conveyor belt wear and extends its service life.

[0055] The sidewall belt conveyor adjustment device provided in this embodiment can quickly and accurately correct the belt deviation phenomenon. Moreover, the slot design allows the adjustment device to adapt to the complex geological conditions and space constraints in ultra-deep vertical shafts, and it is not restricted by the site environment. It is also convenient to install and maintain.

[0056] The above embodiments are only used to illustrate the embodiments of this application, and are not intended to limit the embodiments of this application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the embodiments of this application. Therefore, all equivalent technical solutions also fall within the scope of the embodiments of this application, and the patent protection scope of the embodiments of this application should be defined by the claims.
