Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor equipment, and in particular to a self-adjusting heavy-duty belt conveyor system. Background Technology

[0002] In existing technologies, heavy-duty belt conveyor systems offer advantages over other transportation methods, such as lower maintenance costs, larger capacity, and greater safety and reliability, and are therefore widely used in various fields, including metal and non-metal mines, ports, power plants, and coal yards. However, long-distance belt conveyor systems face several challenges.

[0003] Firstly, traditional long-distance belt conveyor devices have a fixed structure, so they need to be disassembled as a whole to adapt to complex terrain and dynamic working conditions. This makes it difficult to move and set up, takes a long time, involves complicated procedures, and has high labor costs.

[0004] Furthermore, traditional conveying systems lack effective adjustment mechanisms for installation conditions in different geographical environments, such as uneven ground or when it is necessary to bypass obstacles, making it difficult to guarantee the accuracy and stability of the conveying path.

[0007] Firstly, traditional long-distance belt conveyor devices have a fixed structure, so they need to be disassembled as a whole to adapt to complex terrain and dynamic working conditions. This makes it difficult to move and set up, takes a long time, involves complicated procedures, and has high labor costs.

[0008] Furthermore, traditional conveying systems lack effective adjustment mechanisms for installation conditions in different geographical environments, such as uneven ground or when it is necessary to bypass obstacles, making it difficult to guarantee the accuracy and stability of the conveying path.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0011] In a first aspect, this utility model provides a self-adjusting heavy-duty conveyor belt system, including a conveying device, a base assembly, and a first connecting assembly; multiple conveying devices are distributed along their own length.

[0012] Both ends of the conveying device are supported on the base assembly, and the adjacent ends of the conveying devices are connected to the base assembly through a first connecting assembly. The base assemblies can move back and forth.

[0013] The first connecting component can provide the ends of adjacent conveying devices with the freedom to swing back and forth and left and right, and the outer end of the outermost conveying device can swing back and forth relative to the corresponding base component.

[0014] When the base assembly moves back and forth, it enables the corresponding conveying device to move laterally and allows the conveying device to adaptively swing back and forth and / or left and right on the base assembly until the overlap of the centerlines of adjacent conveying devices reaches a threshold.

[0015] In one technical solution of this utility model, the first connecting assembly can also provide the ends of adjacent conveying devices with the freedom to swing along the vertical axis; the first connecting assembly includes a lower movable unit, two upper movable units, and two rotating frames; both the lower movable unit and the upper movable unit include a lower spherical plate and an upper spherical plate with their centers facing upwards; the lower spherical plate and the upper spherical plate corresponding to the lower movable unit are connected to swing back and forth, and the lower spherical plate and the upper spherical plate corresponding to the upper movable unit are connected to swing left and right; the lower spherical plates corresponding to the two upper movable units are fixedly connected to the upper spherical plates corresponding to the lower movable units at left and right intervals; the upper spherical plates corresponding to the two upper movable units are respectively connected to the ends of adjacent conveying devices along the vertical axis through the two rotating frames, and the lower spherical plate corresponding to the lower movable unit is fixedly connected to the base assembly.

[0016] In one technical solution of this utility model, a second connecting component is also included. The outer ends of the outermost conveying devices are all connected to the corresponding base components through the corresponding second connecting component. The second connecting component includes a lower movable unit and a rotating frame. The outer ends of the corresponding conveying devices are rotatably connected to the upper spherical plate of the lower movable unit along the vertical axis through the corresponding rotating frame.

[0017] In one technical solution of this utility model, one of the lower spherical plate and the upper spherical plate is provided with a circumferentially extending groove, and the other of the lower spherical plate and the upper spherical plate is fixedly connected with a sliding pin that is slidably connected in the groove along the length direction of the groove.

[0018] In one technical solution of this utility model, multiple hydraulic support mechanisms are further included, which are fixedly connected to the upper spherical plate corresponding to the lower movable unit. The hydraulic support mechanisms are connected to the outer periphery of the corresponding upper spherical plate. Each hydraulic support mechanism can independently rise and fall vertically to switch between a supported state and a suspended state. In the supported state, the hydraulic support mechanism extends downward to the ground, and the base assembly is supported on the ground by the hydraulic support mechanism to a certain length. In the suspended state, the hydraulic support mechanism shortens upward to the length of the base assembly supported on the ground by the moving mechanism. When the base assembly moves, the hydraulic support mechanism is in a suspended state. When the base assembly stops moving, or when rotating between the left-right driving direction and the front-back driving direction, the hydraulic support mechanism switches to the supported state and can lock the degree of freedom of the corresponding upper spherical plate to swing back and forth.

[0019] In one technical solution of this utility model, the base assembly includes a fixed frame and a moving mechanism connected to the bottom of the fixed frame.

[0020] In one technical solution of this utility model, the moving mechanism is configured as two sets of parallel and spaced tracks.

[0021] In one technical solution of this utility model, the moving mechanism can rotate relative to the vertical central axis of the lower movable unit, so as to change the driving direction by rotating the moving mechanism relative to the fixed frame along the vertical axis through the speed difference of the two sets of tracks.

[0022] In one technical solution of this utility model, a tensioning device and a belt are also included. The belt encloses the entire conveying device. The tensioning device is fixedly connected to one end of the belt conveying system along its own length direction and is suitable for tensioning the belt.

[0023] (III) Beneficial Effects

[0024] The beneficial effects of this utility model are as follows: This self-adjusting heavy-duty conveyor system, through its modular and adjustable structural design, achieves adaptive adjustment of the overall posture of the conveyor belt during long-distance operation. It also enables the heavy-duty long-distance conveyor system to move and be set up quickly without secondary disassembly and assembly. At the same time, under the action of the control unit, it can achieve programmed automation and unmanned operation, significantly shortening the movement and setting time, improving the movement and setting efficiency, and enhancing the adaptability to working conditions.

[0025] The system includes multiple conveying devices arranged sequentially along the conveying direction, a continuous conveyor belt running through all the conveying devices, and a base assembly for supporting and adjusting the overall layout.

[0026] The base assembly serves as the support and adjustment platform for the entire system, enabling movement along the length of the conveying device. Both ends of all conveying devices are supported by the base assembly, and the connection points between adjacent conveying devices can be connected by a first connecting component on the base assembly, allowing for swinging forward and backward as well as left and right. The outer ends of the two outermost conveying devices in the system are allowed to swing back and forth, thus providing the system with necessary flexibility while maintaining the overall structural rigidity.

[0027] When the base assembly moves along the width of the conveyor, the conveyor it supports undergoes lateral displacement. Simultaneously, under the constraint of the base assembly, each conveyor can adaptively oscillate forward and backward and / or left and right with limited amplitude. This oscillation mechanism allows the centerlines of adjacent conveyor devices to align. When the centerline overlap reaches a preset threshold, the system automatically tends towards a geometrically coordinated state, effectively suppressing the risk of belt misalignment, wear, or tearing caused by conveyor path deviation.

Figures 1-5 This invention will be described in detail through specific embodiments. Wherein, directional terms such as "upper" and "lower" are used in this document.

[0047] Example 1:

[0048] Reference Figures 1-5 The present invention provides a self-adjusting heavy-duty conveyor belt system, including a conveying device 110, a base assembly 120 and a first connecting assembly 130; multiple conveying devices 110 are distributed along their own length.

[0049] Both ends of the conveying device 110 are supported on the base assembly 120, and the adjacent ends of the conveying devices 110 are connected to the base assembly 120 through a first connecting assembly 130. The base assembly 120 can move back and forth.

[0050] The first connecting component 130 can provide the ends of adjacent conveying devices 110 with the freedom to swing back and forth and left and right, and the outer end of the outermost conveying device 110 can swing back and forth relative to the corresponding base component 120.

[0051] When the base assembly 120 moves back and forth, it enables the corresponding conveying device 110 to move laterally and to make the conveying device 110 swing adaptively back and forth and / or left and right on the base assembly 120 until the overlap of the center lines of the adjacent conveying devices 110 reaches a threshold.

[0052] In this embodiment, the self-adjusting heavy-duty conveyor belt system, through its modular and adjustable structural design, achieves adaptive adjustment of the overall posture of the conveyor belt during long-distance operation. It also enables the heavy-duty long-distance conveyor belt system to move and be set up quickly without secondary disassembly and assembly. At the same time, under the control unit, it can achieve programmed automation and unmanned operation, significantly shortening the movement and setting time, improving the movement and setting efficiency, and enhancing the adaptability to working conditions.

[0053] The system includes multiple conveying devices 110 arranged sequentially along the conveying direction, a continuous conveyor belt running through all the conveying devices 110, and a base assembly 120 for supporting and adjusting the overall layout.

[0054] The base assembly 120 serves as the support and adjustment platform for the entire system, and has the ability to move along the length of the conveying device 110. Both ends of all conveying devices 110 are supported by the base assembly 120, and the connection points between adjacent conveying devices 110 can be connected by the first connecting assembly 130 on the base assembly 120 to swing back and forth and left and right. The outer ends of the two outermost conveying devices 110 of the system are allowed to swing back and forth, thereby giving the system the necessary degree of flexibility while maintaining the overall structural rigidity.

[0055] When the base assembly 120 moves along the width of the conveyor 110, the conveyor 110 it supports undergoes lateral displacement. Simultaneously, under the constraint of the base assembly 120, each conveyor 110 can adaptively oscillate forward and backward and / or left and right with a limited amplitude. This oscillation mechanism allows the centerlines between adjacent conveyor 110s to align. When the centerline overlap reaches a preset threshold, the system automatically tends towards a geometrically coordinated state, effectively suppressing the risk of belt misalignment, wear, or tearing caused by conveyor path deviation.

[0056] The self-adjusting heavy-duty belt conveyor system also includes a tensioning device 160, which is fixedly connected to one end of the belt conveyor system along its length and is suitable for tensioning the belt. During the lateral movement of the base assembly 120, the tension of the tensioning device 160 can be adjusted appropriately to make it relatively loose, thus balancing the belt tension during the movement of the base assembly and preventing belt damage.

[0057] During system operation, the tension of the conveyor belt is affected by various factors, including changes in material load, thermal expansion and contraction caused by ambient temperature, belt creep due to long-term operation, and localized slack caused by terrain undulations. The tensioning device 160, as the main tensioning unit, provides a larger stroke and higher precision tension compensation capability. It can adopt a hydraulic cylinder structure, directly changing the effective envelope length of the conveyor belt by pushing or pulling the tail roller along the length of the belt, thereby achieving active control of the overall tension.

[0058] Example 2:

[0059] Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0060] The first connecting assembly 130 can also provide the end of the adjacent conveying device 110 with the freedom to swing along the vertical axis;

[0061] The first connecting assembly includes a lower movable unit 131, two upper movable units 132, and two rotating frames 133; both the lower movable unit 131 and the upper movable unit 132 include a lower spherical plate 1301 and an upper spherical plate 1302 with their centers facing upwards; the lower spherical plate 1301 and the upper spherical plate 1302 corresponding to the lower movable unit 131 are connected by swinging back and forth, and the lower spherical plate 1301 and the upper spherical plate 1302 corresponding to the upper movable unit 132 are connected by swinging left and right;

[0062] The lower spherical plates 1301 corresponding to the two upper movable units 132 are fixedly connected to the upper spherical plates 1302 corresponding to the lower movable unit 131 at left and right intervals; the upper spherical plates 1302 corresponding to the two upper movable units 132 are respectively rotatably connected along the vertical axis to the ends of the adjacent conveying devices 110 via two rotating frames 133; the lower spherical plates 1301 corresponding to the lower movable unit 131 are fixedly connected to the base assembly 120.

[0063] The self-adjusting heavy-duty belt conveyor system also includes a second connecting component 140, and the outer ends of the outermost conveying device 110 are all connected to the corresponding base component 120 through the corresponding second connecting component 140.

[0064] The second connecting assembly 140 includes a lower movable unit 131 and a rotating frame 133. The outer end of the corresponding conveying device 110 is rotatably connected to the upper spherical plate 1302 of the lower movable unit 131 along the vertical axis via the corresponding rotating frame 133.

[0065] One of the lower spherical plate 1301 and the upper spherical plate 1302 is provided with a circumferentially extending groove, and the other of the lower spherical plate 1301 and the upper spherical plate 1302 is fixedly connected with a sliding pin that is slidably connected in the groove along the length direction of the groove.

[0066] In this embodiment, the first connecting component 130 and the second connecting component 140 realize multi-directional flexible connection between adjacent conveying devices 110 and between the end conveying device 110 and the base, and provide a basis for the asynchronous lateral movement of the base component 120 by the adjacent conveying devices 110 in conjunction with the tensioning device 160, thereby giving the system a high degree of motion adaptability and attitude adjustment capability while ensuring the overall structural rigidity.

[0067] Specifically, the connection between adjacent conveying devices 110 is not a rigid docking, but rather an indirect coupling to the same base assembly 120 via a first connecting component 130. Each first connecting component 130 includes a lower movable unit 131 and two upper movable units 132, which are connected in a hierarchical multi-degree-of-freedom manner through a spherical plate structure. The lower spherical plate 1301 of the lower movable unit 131 is fixed to the base assembly 120, and its upper spherical plate 1302 serves as an intermediate platform. The lower spherical plates 1301 of the two upper movable units 132 are fixedly connected to the upper spherical plate 1302 at intervals, and each upper spherical plate 1302 is rotatably connected to the corresponding end of the adjacent conveying device 110 along the vertical axis via a rotating frame 133.

[0068] Between each pair of upper and lower spherical plates 1301, one side is provided with a circumferentially extending groove, and the other side is fixed with a matching sliding pin, the two forming a limiting sliding pair. This structure allows the upper and lower spherical plates 1301 to swing around the center of the sphere at a limited angle based on spherical contact, while the movement of the sliding pin in the groove further constrains the direction and range of swing, ensuring that the connection is both flexible and controllable.

[0069] Thus, the adjacent conveying devices 110 can achieve coordinated limited oscillation in the front-back and left-right directions under the support of the base assembly 120, thereby enabling adaptive adjustment of the position of the conveying devices 110.

[0070] For the two outermost conveying devices 110 of the system, their outer ends, i.e., the ends not adjacent to other conveying devices 110, are connected to the corresponding base assembly 120 via the second connecting assembly 140. The second connecting assembly 140 has a simpler structure, including a lower movable unit 131 and a rotating frame 133. Its lower spherical plate 1301 is fixed to the base assembly 120, and its upper spherical plate 1302 is connected to the outermost frame unit via the rotating frame 133. This connection method retains limited forward and backward swing capability and rotation capability along the vertical axis, thereby forming a flexible constraint at the end, which enables the adjustment of the position of the conveying device 110.

[0071] Overall, the introduction of the first connecting component 130 and the second connecting component 140 enables the entire conveying system to have a high degree of coordination when the base assembly 120 moves in both directions: when the base moves laterally along the width direction, the spherical side effects in the first connecting component 130 and the second connecting component 140 guide adjacent conveying devices 110 to automatically adjust their relative posture during the lateral movement, promoting dynamic alignment of their center lines until the overlap meets the operating threshold. This multi-layered, multi-degree-of-freedom flexible connection mechanism not only significantly improves the adaptability of long-distance belt conveyor systems to complex installation environments and dynamic working conditions, but also effectively reduces the risks of belt misalignment, abnormal wear of idlers, and structural fatigue, thereby ensuring the long-term, stable, and efficient operation of the system.

[0072] Furthermore, since the conveying device 110 has the freedom to rotate along the vertical axis relative to the base assembly 120, when the base assembly 120 moves laterally, even if there is a speed difference, i.e., different base assemblies 120 move asynchronously, the angle fine adjustment between adjacent conveying devices 110 can be adaptively completed within the range allowed by the belt and tensioning device 160.

[0073] Specifically, the swing range of the outermost end of the conveying device 110 along the vertical axis can be limited to 10°, while the swing angle of the corresponding ends of adjacent conveying devices 110 along the vertical axis to both sides in each width direction can be limited to 15°.

[0074] Example 3:

[0075] Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0076] It also includes multiple hydraulic support mechanisms 150 fixedly connected to the upper spherical plate 1302 corresponding to the lower movable unit 131. The hydraulic support mechanisms 150 are connected to the outer periphery of the corresponding upper spherical plate 1302. Each hydraulic support mechanism 150 can independently rise and fall vertically to switch between a supported state and a suspended state. In the supported state, the hydraulic support mechanism 150 extends downward to the ground, and the base assembly 120 is supported on the ground by the hydraulic support mechanism 150 to that length. In the suspended state, the hydraulic support mechanism 150 shortens upward to the length of the base assembly 120 supported on the ground by the moving mechanism 122. When the base assembly 120 moves, the hydraulic support mechanism 150 is in the suspended state; when the base assembly 120 stops moving, or when rotating between the left-right driving direction and the front-back driving direction, the hydraulic support mechanism 150 switches to the supported state.

[0077] In this embodiment, the hydraulic support mechanism 150 combines the support function with the motion degree-of-freedom control of the first connecting component 130 and the second connecting component 140, realizing a seamless switch from "dynamic adjustment" to "static locking", which significantly improves the operational stability of the system after the attitude adjustment is completed.

[0078] Each hydraulic support mechanism 150 can independently extend and retract vertically, and has two working states: In the supported state, the hydraulic support mechanism 150 extends downward until its supporting end contacts the ground or foundation platform, and raises the entire base assembly 120 to a predetermined height. At this time, the system load is mainly borne by the hydraulic support mechanism 150; In the suspended state, the hydraulic support mechanism 150 retracts upward, causing the base assembly 120 to drop as a whole, and the weight is transferred to the moving mechanism 122, i.e., the dual track unit, and the system enters the movable mode.

[0079] The hydraulic support mechanism 150 not only provides load support but also locks the degrees of freedom. When the base assembly 120 moves along the width of the conveying device 110, causing the conveying device 110 to move laterally, and the spherical and sliding pairs in the first connecting assembly 130 align the centerlines of adjacent conveying devices 110, the control system can instruct the hydraulic support mechanism 150 to switch to the support state. At this time, the hydraulic support mechanism 150 extends downward and is firmly supported on the ground. Simultaneously, because it is fixed to the upper spherical plate 1302, its rigid support effect will conversely constrain the position of the upper spherical plate 1302, thereby limiting the overall degrees of freedom of movement of the lower movable unit 131. Specifically, the spherical connection, which originally allowed the conveyor 110 to swing to a limited extent along its width, has its swing freedom effectively suppressed after hydraulic support locking. This restricts the posture of the conveyor 110 to the ideal position after alignment, allowing the system to maintain sufficient flexibility to adapt to path deviations during dynamic adjustment. Once in stable operation, it can quickly transition to a rigid support state, preventing misalignment of the aligned conveyor sections due to vibration, load fluctuations, or external disturbances. Simultaneously, since each hydraulic support mechanism 150 can be independently controlled, even on uneven ground, local leveling and precise locking can be achieved through differentiated adjustments, ensuring a high degree of consistent geometric accuracy throughout the long-distance operation of the entire conveyor line.

[0080] Example 4:

[0081] Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0082] The base assembly 120 includes a fixed frame 121 and a moving mechanism 122 connected to the bottom of the fixed frame 121. The moving mechanism 122 is configured with two sets of parallel, spaced-apart tracks. The moving mechanism 122 is rotatable relative to the vertical central axis of the lower movable unit 131, so as to change the driving direction by rotating the moving mechanism 122 relative to the fixed frame 121 along the vertical axis through the speed difference between the two sets of tracks.

[0083] The moving mechanism 122 can rotate relative to the lower movable unit 131 along the vertical axis. The following connection method can be adopted: the moving mechanism 122 is fixedly connected to the fixed frame 121, and the lower movable unit 131 is hinged to the fixed frame 121 along the vertical axis. In this way, when the moving mechanism 122 turns, it can rotate relative to the lower movable unit to complete the switching between the left and right driving direction and the front and back driving direction.

[0084] In this embodiment, the base assembly 120 of the self-adjusting heavy-duty conveyor belt system adopts a composite mobile mechanism 122 that combines walking, steering and multi-directional driving capabilities, which significantly improves the deployment flexibility and operational adaptability of the whole machine in complex terrain.

[0085] The moving mechanism 122 is hinged to the lower movable unit 131 via a vertical axis. It can not only drive the entire fixed frame 121 to move along the ground, but also rotate freely around the vertical axis relative to the lower movable unit 131, thereby realizing dynamic switching of the driving direction.

[0086] Specifically, the moving mechanism 122 is configured with two sets of parallel and spaced-apart track units. These two sets of tracks can operate synchronously to achieve straight-line travel, or they can generate a steering torque about the vertical axis by adjusting the speed difference between them, causing the moving mechanism 122 to rotate relative to the fixed frame 121. With this differential steering mechanism, the system can flexibly switch between preset driving directions. This design, which combines dual-track differential drive with vertical hinged rotation, allows the base assembly 120 to achieve direction switching without an additional steering mechanism, resulting in a compact structure, rapid response, and clear control logic.

[0087] In summary, the base assembly 120, by integrating differential track drive and vertical rotational hinge structure, effectively solves the problem that fixed or unidirectional mobile bases are difficult to balance path alignment and on-site adaptability in long-distance scenarios, and significantly improves the system's intelligence level and engineering practicality.

[0088] Furthermore, the conveying device 110 has multiple components distributed along its length, each including a frame unit 111 and a sliding unit 112. The sliding unit 112 is slidably connected to one end of the frame unit 111 along its length. A tape wraps around all the conveying devices 110. The base assembly 120 is adapted to support the conveying device 110 and can move along the length and width of the conveying device 110. Both ends of the conveying device 110 are supported by the base assembly 120. Each conveying device 110 can swing back and forth and left and right, and is connected to the corresponding base assembly 120 in a manner that allows rotation along the vertical axis. The outermost ends of the outermost conveying device 110 can swing back and forth. It is connected to the corresponding base assembly 120 in a manner that allows rotation along the vertical axis; when the base assembly 120 moves along the width direction of the conveying device 110, it enables the corresponding conveying device 110 to adaptively move on the base assembly 120 in one or more combinations of motion forms such as back-and-forth swinging, left-and-right swinging, or rotation along the vertical axis until the overlap of the center lines of adjacent conveying devices 110 reaches a threshold; when the base assembly 120 moves along the length direction of the conveying device 110, it enables the corresponding sliding unit 112 to slide along the length direction of the conveying device 110, thereby enabling the tape to be further tightened / slackened and providing conditions for the asynchronous lateral movement of the conveying device 110.

[0089] Based on the above embodiments, a sliding unit 112 is further introduced. By sliding the sliding unit 112 relative to the frame unit 111, the tape can be further tightened or loosened, thereby providing a hardware basis for the asynchronous movement of the base assembly 120. In this way, asynchronous lateral movement can be achieved without making major adjustments to the tensioning device 160.

[0090] It also includes a control center 170, a moving mechanism 122, a hydraulic support mechanism 150, and a tensioning device 160, all of which are connected to the control center 170 to control the operation through the control center 170.

[0091] It also includes a support detection unit 180, a centerline detection unit 190, a steering position detection unit 200, and a sliding position detection unit 210 connected to the control center 170;

[0092] The support detection unit 180 is fixedly connected to the hydraulic support mechanism 150 and is suitable for detecting the liquid pressure of the hydraulic support mechanism 150 to obtain the support status of the hydraulic support mechanism 150.

[0093] The centerline detection unit 190 is fixedly connected to the frame unit 111 and is suitable for detecting the centerline of the conveying device 110 and thus determining the overlap of the centerlines of adjacent conveying devices 110.

[0094] The steering position detection unit 200 is fixedly connected to the moving mechanism 122 and is suitable for detecting the rotation angle of the moving mechanism 122 relative to the lower movable unit 131;

[0095] The sliding position detection unit 210 is fixedly connected to the sliding unit 112 and is suitable for detecting the sliding position of the sliding unit 112 relative to the frame unit 111.

[0096] In this embodiment, the heavy-duty long-distance conveyor belt system introduces a control center 170 and various high-precision detection units to construct a closed-loop intelligent control system of perception-decision-execution. This system enables real-time monitoring and automatic adjustment of the overall machine attitude, belt tension, support status, and movement positioning, significantly improving the system's automation level, operational accuracy, and fault response capability.

[0097] The control center 170, as the core brain of the system, is electrically or electro-hydraulic linked with the moving mechanism 122, the hydraulic support mechanism 150, and the tensioning device 160. It can coordinate the action sequence and operating parameters of each execution unit according to preset logic or real-time feedback signals. On this basis, the system integrates four types of key detection units, corresponding to the precise perception of support status, path alignment, steering angle, and sliding position.

[0098] The support detection unit 180 is installed on the hydraulic support mechanism 150. By monitoring the liquid pressure in the hydraulic chamber in real time, it indirectly determines whether the support mechanism has fully extended and can effectively bear the load. When the pressure value reaches the preset threshold, it indicates that the hydraulic support has entered a stable support state. Based on this, the control center 170 confirms that the whole machine has switched from the mobile mode to the fixed operation mode, and can further lock the swing degree of freedom of the connecting components. If the pressure is abnormal, an alarm can be triggered or the machine can automatically return to the suspended state to prevent structural instability due to support failure.

[0099] The centerline detection unit 190 is fixed on the frame unit 111 of each conveyor device 110. It can use technologies such as laser beam, visual recognition, and displacement sensors such as inertial navigation sensors to continuously acquire the centerline position of the current section of the conveyor device 110 and compare it with the data of adjacent sections to calculate the centerline coincidence. When the base assembly 120 moves laterally along the width direction for centering adjustment, the control center 170 dynamically adjusts the travel amount and direction of the moving mechanism 122 based on the feedback from the centerline detection unit 190 until the coincidence meets the set threshold. This ensures that the conveyor belt has a continuous trajectory without steps or misalignment when crossing multiple sections of the conveyor device 110, fundamentally suppressing the risk of deviation.

[0100] The steering positioning detection unit 200 is integrated on the moving mechanism 122 and is used to monitor its rotation angle relative to the lower moving unit 131 about the vertical axis in real time. When the system needs to switch the drive mode between the length and width directions, the control center 170 drives the two sets of tracks to generate differential speed, causing the moving mechanism 122 to rotate. Once the steering positioning detection unit 200 confirms that the rotation angle has reached the preset target value of 90°, it sends a positioning signal to the control center 170 to stop the steering action, ensuring the accuracy of the movement direction switching and the repeatability of the positioning.

[0101] The sliding position detection unit 210 is arranged on the sliding unit 112 to detect its sliding stroke relative to the frame unit 111. During the movement of the base assembly 120 along its length to adjust the tape tension, this detection unit provides real-time feedback on the sliding position, enabling the control center 170 to precisely control the tension stroke and prevent over-tensioning leading to tape damage or under-tensioning causing slippage. Simultaneously, this signal can be cross-checked with the displacement data of the tensioning device 160, achieving dual protection for tension control.

[0102] Through the deep integration of the aforementioned detection units and actuators under the control center 170, the system achieves a complete control closed loop of "perception-judgment-execution-verification". For example, in a complete alignment and tensioning process: the control center 170 first instructs the moving mechanism 122 to move laterally, and the centerline detection unit 190 provides real-time feedback on the alignment deviation until the target is met; then the hydraulic support mechanism 150 is lowered, and after the support detection unit 180 confirms the support is effective, the control center 170 locks the swing degree of freedom; next, the sliding unit 112 fine-tunes its position, and the sliding position detection unit 210 confirms the tensioning stroke, and if necessary, the tensioning device 160 provides supplementary tensioning. The entire process requires no manual intervention, with rapid response and precise action.

[0103] In summary, this system not only possesses flexibility and adaptability in its mechanical structure, but also upgrades long-distance conveyor belt transportation from the traditional "rigid fixing + manual maintenance" mode to an intelligent conveying platform that is "self-sensing, self-adjusting, and self-stabilizing" through an intelligent sensing and control architecture, greatly improving reliability and operational efficiency in complex, dynamic, and unmanned operating environments.

[0104] Example 5:

[0105] Figures 1-5 This utility model provides an adjustment method for a heavy-duty long-distance conveyor belt system, used in the above-described heavy-duty long-distance conveyor belt system. The method includes:

[0106] S1: Pre-relax the tape;

[0107] S2: In the direction from downstream to upstream of the belt conveyor system, the base assembly 120 drives the corresponding conveying device 110 to move sequentially upstream of the belt conveyor system, and causes the corresponding sliding unit 112 to slide to the limit position relative to the corresponding frame unit 111 in the upstream direction of the belt conveyor, thereby further loosening the belt.

[0108] S3: The base assembly 120 drives the corresponding conveying device 110 to move along the width direction of the conveying device 110, and the corresponding conveying device 110 adapts to one or more combinations of motion forms on the base assembly 120, such as back-and-forth swinging, left-and-right swinging, or rotation along the vertical axis, until the overlap of the center lines of adjacent conveying devices 110 reaches a threshold.

[0109] S4: Following the direction from upstream to downstream of the belt conveyor system, the base assembly 120 drives the corresponding conveying device 110 to move sequentially downstream of the belt conveyor system, and causes the corresponding sliding unit 112 to slide relative to the corresponding frame unit 111 to the downstream direction of the belt conveyor to the set position, thereby causing the belt to finally tighten.

[0110] S1 specifically includes:

[0111] S1.1: Allow the tensioning device 160 to slide, thereby pre-relaxing the tape;

[0112] S2 specifically includes:

[0113] S2.1: Switch the hydraulic support mechanism 150 to the suspended state and switch the moving mechanism 122 to the left and right driving direction;

[0114] S2.2: In the direction from downstream to upstream of the belt conveyor system, the base assembly 120 drives the corresponding conveying device 110 to move sequentially upstream of the belt conveyor system, and causes the sliding unit 112 to slide to the limit position upstream of the belt conveyor, thereby further loosening the belt.

[0115] S3 specifically includes:

[0116] S3.1: Switch the hydraulic support mechanism 150 to the support state and switch the moving mechanism 122 to the forward and backward driving direction, then switch the hydraulic support mechanism 150 to the suspended state.

[0117] S3.2: The moving mechanism 122 drives the base assembly 120 to move until the overlap of the centerlines of the adjacent conveying devices 110 reaches the threshold.

[0118] The moving mechanism 122 drives the base assembly 120 to move, specifically as follows:

[0119] All moving mechanisms 122 can move synchronously; or, the moving mechanisms 122 can move asynchronously in order from upstream to downstream.

[0120] S4 specifically refers to:

[0121] S4.1: Switch the hydraulic support mechanism 150 to the support state and switch the moving mechanism 122 to the left and right driving direction, then switch the hydraulic support mechanism 150 to the suspended state.

[0122] S4.2: Move the conveying device 110 one by one in the direction from upstream to downstream of the belt conveyor system and slide the sliding unit 112 to the set position in the direction downstream of the belt conveyor, thereby pre-tensioning the belt.

[0123] S4.3: Switch the hydraulic support mechanism 150 to the support state;

[0124] S4.4: Slide the tensioning device 160 to further tighten the tape.

[0125] In this embodiment, the adjustment method for the heavy-duty long-distance conveyor belt system proposes a systematic, time-sequential, and closed-loop controllable full-process operation strategy for belt relaxation-alignment-tensioning, based on the structural characteristics of the aforementioned heavy-duty long-distance conveyor belt system. This effectively solves the technical problem that traditional long-distance multi-segment conveyor belt systems are difficult to simultaneously achieve path alignment and precise tension control after installation, maintenance, or changes in working conditions.

[0126] The method first achieves initial relaxation of the tape through step S1, reserving sufficient movement space for subsequent adjustments. Specifically, in S1.1, the control center 170 drives the tensioning device 160 to reverse its movement, pre-relaxing the tape as a whole, thus preventing structural jamming, tape tearing, or the sliding unit 112 failing to reach its position due to excessive tension during the subsequent movement of the conveying device 110.

[0127] Entering stage S2, the system releases the conveyor belt segment by segment from downstream to upstream. In S2.1, the hydraulic support mechanism 150 first switches to a suspended state, allowing the weight of the base assembly 120 to be fully supported by the moving mechanism 122. Simultaneously, the moving mechanism 122 switches to the left-right driving direction, i.e., the direction of the conveyor belt length, preparing for longitudinal movement. Then, in S2.2, the control center 170 sequentially instructs each base assembly 120 to move its corresponding conveyor device 110 upstream, pushing the sliding unit 112 to synchronously slide along the frame unit 111 to its upstream limit position. This process essentially "compresses" the conveyor devices 110, accumulating maximum slack along the entire line, providing a free state without tension interference for subsequent lateral alignment, and preventing the conveyor belt from hindering the swing and lateral movement of the conveyor device 110 due to tension.

[0128] Phase S3 focuses on path geometric alignment. In S3.1, the system briefly switches the hydraulic support mechanism 150 to a supported state, temporarily fixing the posture of the conveyor 110. Then, the moving mechanism 122 is switched to the forward / backward driving direction (width direction), and the hydraulic support is retracted to a suspended state, ensuring smooth turning and preventing the turning process from affecting the position of the conveyor 110. In S3.2, the moving mechanism 122 drives the base assembly 120 to move along the width direction, causing the conveyor 110 to adaptively swing within the allowable range of the spherical and sliding pairs of the first connecting assembly 130. During this process, the centerline detection unit 190 provides real-time feedback on the centerline deviation of adjacent segments, and the control center 170 dynamically adjusts the lateral movement accordingly until the overlap reaches a preset threshold. Lateral movement can be performed in two modes: one is synchronous movement of all moving mechanisms 122, suitable for scenarios with small overall offset and flat terrain; the other is asynchronous movement, suitable for situations with local misalignment or large terrain undulations, achieving more refined path fitting through segmented fine-tuning.

[0129] After alignment, the system enters the S4 tensioning stage. In S4.1, the moving mechanism 122 is accurately aligned with the left and right drive directions again to prepare for tensioning. In S4.2, the control center 170 drives the base assembly 120 downstream one by one, from upstream to downstream, causing the sliding unit 112 to slide synchronously to the downstream set position. This ensures that the belt tension is transmitted segment by segment along the conveying direction, preventing the downstream from tightening first, which could lead to belt accumulation or jamming of the sliding unit 112. This process achieves "pre-tensioning" of the belt, establishing a basic tension. Subsequently, in S4.3, the hydraulic support mechanism 150 switches to the support state, rigidly fixing each conveying device 110 to the ground, locking its spatial position and swing freedom, and providing a stable reference for final tensioning. Finally, in S4.4, the control center 170 drives the tensioning device 160 to move forward, applying a precise final tension force to the belt, compensating for system elastic deformation and operating load requirements, so that the belt reaches the designed tension value.

[0130] The entire adjustment method fully utilizes the synergistic capabilities of the sliding unit 112, the base moving mechanism 122, and the hydraulic support and tensioning device 160 within the system, and relies on various detection units to achieve process feedback and positioning confirmation. Its advantages are: first, it avoids alignment failure or stress concentration caused by traditional "one-time tensioning"; second, through segmented and orderly operation, it ensures the geometric continuity and mechanical consistency of long-distance, multi-segment structures; and third, the entire process can be automatically executed by the control center 170, significantly reducing the need for manual intervention and operational risks.

[0131] Therefore, this adjustment method not only improves the installation and commissioning efficiency and operational reliability of heavy-duty long-distance belt conveyor systems, but also provides a feasible technical path for online dynamic maintenance under complex working conditions, and has significant engineering application value.
