[0002] In coal transportation operations, belt conveyor systems are a key technology for ensuring efficient and safe coal transport. Currently, most belt conveyor systems rely on electrical control devices, which offer advantages such as high precision and fast response. However, due to the high dust and humidity at coal transportation sites, electrical devices suffer from short lifespans and high failure rates, affecting the normal operation of the belt conveyor system and compromising its reliability.

[0012] In one embodiment, the support further includes legs for supporting the diagonal bracing beam;

[0013] The linkage assembly includes a first link, a second link, a third link, a fourth link, and a connecting handle that are hinged sequentially. The end of the first link away from the second link is hinged to the insertion section. The center of the second link is hinged to the support leg via a pin. The fourth link and the connecting handle are both horizontally positioned. The end of the connecting handle away from the fourth link is hinged to the end of the rotating rod away from the bracket. The connecting handle is capable of rotating in the horizontal plane. The first link, the second link, and the third link all rotate in the same vertical plane.

[0014] Wherein, the angle between the second link and the third link is α, and the angle between the third link and the fourth link is β, then both α and β are acute angles.

[0015] In one embodiment, the support frame is symmetrically arranged along the center of the middle crossbeam, and the middle crossbeam and the support beam enclose a support groove. Along the forward direction, the outer contour of the support and the projection of the support frame coincide.

[0016] In one embodiment, there are two sets of the correction structure, each of which corresponds to one of the diagonal bracing beams, and the belt is positioned between the two sets of correction structures.

[0017] In one embodiment, the detection roller is rotatably mounted on the connecting section.

[0018] In one embodiment, the support frame further includes a mounting base, which is mounted on the support beam. The mounting base includes a first main body and a first mounting shaft, and the two ends of the roller are rotatably connected to the first main body through the first mounting shaft.

[0019] The bracket includes a second body and a second mounting shaft, and the two ends of the roller are rotatably connected to the second body via the second mounting shaft.

[0020] In one embodiment, the second main body has an oblong through hole, and the top of the rotating rod has an oblong protrusion. The oblong through hole and the oblong protrusion are configured to cooperate with each other so that the bracket and the rotating rod rotate synchronously.

[0021] In one embodiment, the socket is shaped like a regular prism, and the outer contour of the insertion segment is adapted to the regular prism to prevent the insertion segment from rotating relative to the socket.

[0022] This utility model also proposes a conveyor belt, including a belt correction device as described in any of the above embodiments, wherein the conveyor belt further includes a drive motor and the belt, and the drive motor is used to drive the belt to move.

[0023] In one embodiment, multiple belt alignment devices are arranged parallel to each other at intervals along the extension direction of the conveyor belt.

[0024] According to the technical solution of this utility model, the belt correction device includes idlers, a support frame, a steering assembly, a bracket, and a correction structure. The idlers support the belt; the support frame includes a central crossbeam and support beams disposed on both sides of the central crossbeam; the steering assembly includes a bracket and a rotating rod, the rotating rod being rotatably mounted on the central crossbeam, and the bracket being mounted on the rotating rod relative to the central crossbeam, with at least one idler mounted on each support beam and bracket; the bracket includes a diagonal brace parallel to the support beams, with a limiting seat mounted on the diagonal brace, the limiting seat having an insertion hole; the correction structure includes a detection vertical roller, an L-shaped rod, and a connecting rod assembly, the L-shaped rod including an insertion section and a connecting section, the insertion section being slidably mounted in the insertion hole, the detection vertical roller being mounted on the connecting section, one end of the connecting rod assembly being hinged to the insertion section, and the other end being hinged to the end of the rotating rod away from the bracket, the detection vertical roller being able to pull the rotating rod to rotate via the L-shaped rod and the connecting rod assembly; wherein, the direction from the bracket to the support frame is the forward direction, and the belt moves along the forward direction. With this setup, when the belt shifts to one side, it contacts the detection roller. Under the belt's influence, the detection roller moves away from the inclined support beam, causing the L-shaped rod to move. This, in turn, pulls the rotating rod in the same direction as the belt's shift via the linkage assembly. This causes the bracket to rotate the idler roller at its top in the opposite direction. As the belt continues to move forward, the friction between the belt and the idler roller gradually returns the belt to its correct position, thus correcting its deviation. In this way, the belt correction process can be automatically completed using only mechanical structures, without relying on electrical devices, thereby improving the reliability of the belt correction device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] In the coal industry, coal transportation relies heavily on conveyor belts. During operation, coal moves directionally along the conveyor belt to its designated area. The use of conveyor belts significantly improves coal transportation efficiency. However, due to the uneven distribution of coal on the belt, belt misalignment can occur after a certain period of operation. This misalignment can lead to coal spillage and other safety accidents. Therefore, a belt alignment system is a key technology for ensuring efficient and safe coal transportation.

[0044] However, the applicant's observations and research revealed that currently used belt conveyor systems are primarily controlled by electrical devices. Coal transportation sites are characterized by high dust concentrations and high humidity. These environmental characteristics lead to frequent malfunctions of the electrical devices, affecting the normal operation of the belt conveyor systems and compromising their reliability. If the electrical devices are not regularly and properly maintained, belt deviations may not be effectively controlled, potentially causing significant coal spillage and accumulation, and even, in extreme cases, belt tearing. These malfunctions not only disrupt production processes but can also result in substantial economic losses.

[0045] In view of the above, this utility model proposes a belt alignment device to solve the above problems.

[0046] Please see Figures 1 to 3In one embodiment of this utility model, the belt alignment device 100 includes an idler roller 1, a support frame 2, a steering assembly 3, a bracket 4, and an alignment structure 5. The idler roller 1 carries the belt 200; the support frame 2 includes a central crossbeam 21 and support beams 22 disposed on both sides of the central crossbeam 21; the steering assembly 3 includes a bracket 31 and a rotating rod 32, the rotating rod 32 being rotatably mounted on the central crossbeam 21, and the bracket 31 being mounted on the rotating rod 32 relative to the central crossbeam 21; both the support beams 22 and the bracket 31 are each equipped with at least one idler roller 1; the bracket 4 includes a diagonal brace 41 parallel to the support beams 22, the diagonal brace 41 being equipped with a limiting seat 42, the limiting seat 42 having an insertion hole; the alignment structure 5 includes a detection vertical roller 5. 1. L-shaped rod 52 and connecting rod assembly 53. L-shaped rod 52 includes insertion section 521 and connecting section 522. Insertion section 521 is slidably installed in insertion hole. Detection roller 51 is installed in connecting section 522. One end of connecting rod assembly 53 is hinged to insertion section 521, and the other end is hinged to the end of rotating rod 32 away from bracket 31. Detection roller 51 can pull rotating rod 32 to rotate through L-shaped rod 52 and connecting rod assembly 53. The direction from bracket 4 to support frame 2 is the forward direction, and belt 200 moves along the forward direction.

[0047] For the direction of travel, please refer to [link / reference]. Figure 1 and Figure 2 The direction indicated by the middle arrow "forward". Both the support frame 2 and the bracket 4 are supported on the ground, and the belt 200 moves continuously along the forward direction on multiple idlers 1. When the belt 200 deviates, taking a rightward deviation as an example, after the belt 200 deviates to the right, it will push the detection roller 51 to move upward and to the right along the insertion hole in the limit seat 42, thereby driving the connecting section 522 and the insertion section 521 of the L-shaped rod 52 to move upward and to the right, which in turn drives the connecting rod assembly 53 to rotate. The connecting rod assembly 53 has multiple sets of rotating pairs, which can convert the displacement transmitted by the insertion section 521 into a force that pulls the rotating rod 32 to move, causing the rotating rod 32 to deviate to the right. Since the rotating rod 32 is rotatably mounted on the middle crossbeam 21, the rotating rod 32 drives the bracket 31 to rotate around the hinge point between the rotating rod 32 and the middle crossbeam 21, causing the support beam 22 to rotate counterclockwise to the left and forward. This, in turn, causes the idler roller 1 on the bracket 31 to rotate counterclockwise. At this time, the friction between the belt 200 and the idler roller 1 increases. As the belt 200 continues to move forward, the friction between the belt 200 and the idler roller 1 causes the belt 200 to gradually return to center. During the process of the belt 200 gradually returning to center, the force exerted by the edge of the belt 200 on the detection roller 51 gradually decreases, causing the rotation angle of the bracket 31 to gradually decrease, which in turn gradually decreases the friction between the idler roller 1 and the belt 200 until the bracket 31 and the belt 200 return to center simultaneously. The return-to-center processes of the bracket 31 and the belt 200 influence each other, ultimately realizing the automatic correction function of the belt 200.

[0048] According to the technical solution of this embodiment, since a bracket 4 is set on one side of the support frame 2, a steering component 3 is set on the support frame 2, and a correction structure 5 is set on the bracket 4, and the correction structure 5 is hinged to the steering component 3, the belt 200 correction process can be automatically completed through mechanical structure only, without relying on electrical devices, thereby improving the reliability of the belt correction device 100 and reducing the probability of safety accidents or production accidents. It should be noted that in the technical solution provided in this embodiment, the rotating rod 32 only needs to drive the bracket 31 to rotate. Compared with the solution of using the rotating rod 32 to drive the entire support frame 2 to rotate, the external force required for the rotation of the rotating rod 32 is smaller, the rotation is more sensitive, and the steering component 3 responds more promptly to the belt 200 deviation. Furthermore, when the bracket 31 rotates, it only changes the direction of one idler roller 1 installed above it, without affecting the direction of the idler roller 1 installed on the support beam 22. This ensures the stability of the belt 200 during movement. Compared to the scheme of using the rotating rod 32 to drive the entire support frame 2 to rotate, thereby changing the rotation direction of all idler rollers 1 on the support frame 2, this scheme can gradually correct the direction of the belt 200 while ensuring the stability of the belt 200's movement, and can avoid the situation where the belt 200 deviates excessively in the correction direction as much as possible.

[0049] Furthermore, in one embodiment of this utility model, please refer to... Figures 2 to 4 The bracket 4 also includes a support leg 43, which supports the diagonal brace beam 41. The linkage assembly 53 includes a first link 531, a second link 532, a third link 533, a fourth link 534, and a connecting handle 535, which are hinged in sequence. The end of the first link 531 away from the second link 532 is hinged to the insertion section 521. The center of the second link 532 is hinged to the support leg 43 by a pin. The fourth link 534 and the connecting handle 535 are both horizontally arranged. The end of the connecting handle 535 away from the fourth link 534 is hinged to the end of the rotating rod 32 away from the bracket 31. The connecting handle 535 can rotate in the horizontal plane. The first link 531, the second link 532, and the third link 533 all rotate in the same vertical plane. The included angle between the second link 532 and the third link 533 is α, and the included angle between the third link 533 and the fourth link 534 is β. Both α and β are acute angles.

[0050] Taking the rightward shift of belt 200 as an example (see section 3), after belt 200 shifts to the right, it pushes the detection roller 51, causing the L-shaped rod 52 to move upward and to the right. At this time, since the first connecting rod 531 is hinged to the insertion section 521 and the second connecting rod 532 is connected to the support leg 43 via a pin, the first connecting rod 531 rotates clockwise with the insertion section 521, and the hinge point between the first connecting rod 531 and the second connecting rod 532 moves upward. Meanwhile, the second connecting rod 532 rotates counterclockwise under the influence of the first connecting rod 531, with the pin as the center of rotation. The displacement at the hinge point between the second connecting rod 532 and the third connecting rod 533 can be decomposed into vertical displacement and directional displacement. Since the angle between the second connecting rod 532 and the third connecting rod 533 is acute, the second connecting rod 532 transmits thrust to the third connecting rod 533, causing the third connecting rod 533 to rotate counterclockwise and move to the right. Because the angle between the third link 533 and the fourth link 534 is acute, the third link 533 transmits tension to the fourth link 534. The vertical displacement generated by the second link 532 is offset by the third link 533. Therefore, the fourth link 534 will only move horizontally and to the right. The two ends of the connecting handle 535 are hinged to the fourth link 534 and the rotating rod 32 respectively, forming a revolute joint. Please refer to [link to relevant documentation]. Figure 4 This configuration allows the fourth link 534 to pull the end of the rotating rod 32 away from the bracket 31 to the right via the connecting handle 535, thereby causing the bracket 31 to rotate to the left front, and ultimately causing the idler roller 1 to rotate to the left front. This embodiment provides a specific implementation of the link assembly 53, which has the advantages of simple structure, easy maintenance, and no reliance on electrical transmission. The connecting handle 535 can be a Z-shaped crank.

[0051] In one embodiment of this utility model, please refer to Figure 3 The support frame 2 is symmetrically arranged along the center of the central crossbeam 21. The central crossbeam 21 and the support beam 22 enclose a support groove. Along the forward direction, the outer contour of the support 4 coincides with the projection of the support frame 2. Specifically, the support frame 2 and the support 4 have the same structure, both adopting a groove design, allowing the belt 200 to form a groove. Coal is contained in the groove for transportation, which can effectively prevent loose coal from scattering during transportation. At the same time, this arrangement can also reduce the possibility of the belt 200 deviating to one side, further reducing the probability of safety accidents or production accidents caused by coal slippage.

[0052] In one embodiment of this utility model, there are two sets of correction structures 5, each corresponding to a diagonal brace beam 41. The belt 200 is positioned between the two sets of correction structures 5. By providing correction mechanisms on both sides of the belt 200, any deviation of the belt 200 to either side can be corrected. It should be noted that in the two sets of correction mechanisms, the length of the connecting handle 535 is greater than the distance between the fourth connecting rod 534 and the rotating rod 32. Please refer to [link to relevant documentation]. Figure 4 The connecting handle 535 is tilted, which allows the rotating rod 32 to swing within a certain range, thus avoiding the situation where the fourth link 534 on the left cannot pull the rotating rod 32 when it is pulled to the left due to the presence of the correction structure 5 on the right.

[0053] In one embodiment of this utility model, the detection roller 51 is rotatably mounted on the connecting section 522. A central shaft is provided at the end of the connecting section 522 of the L-shaped rod 52, and the detection roller 51 is rotatably sleeved on the central shaft. By rotatably mounting the detection roller 51 on the connecting section 522, the tangential friction between the belt 200 and the detection roller 51 is reduced when they come into contact, thereby avoiding affecting the movement of the belt 200.

[0054] In one embodiment of this utility model, please refer to Figure 2 and Figure 5 The support frame 2 also includes a mounting base 23, which is mounted on the support beam 22. The mounting base 23 includes a first main body and a first mounting shaft, and the two ends of the idler roller 1 are rotatably connected to the first main body through the first mounting shaft. The bracket 31 includes a second main body and a second mounting shaft, and the two ends of the idler roller 1 are rotatably connected to the second main body through the second mounting shaft. The idler roller 1, which is set in the mounting base 23, has its axis parallel to the extension direction of the support beam 22 and perpendicular to the forward direction of the belt 200. By rotating the mounting idler roller 1 through the mounting base 23 and the bracket 31, the friction between the belt 200 and the idler roller 1 is reduced, thereby reducing the wasted work during the operation of the belt 200.

[0055] In one embodiment of this utility model, please refer to Figure 5 The second main body has an oblong through hole, and the top of the rotating rod 32 has an oblong protrusion 321. The oblong through hole and the oblong protrusion 321 are fitted together to make the bracket 31 and the rotating rod 32 rotate synchronously. The non-circular cross-section of the oblong structure can effectively transmit torque and ensure that the rotating rod 32 and the bracket 31 rotate synchronously. The machining cost of the oblong hole is lower than that of precision gears or splines, making it suitable for mass production. At the same time, standardized design can improve interchangeability.

[0056] In one embodiment of this utility model, the shape of the insertion hole is a regular prism, and the outer contour of the insertion segment 521 is adapted to the regular prism to prevent the insertion segment 521 from rotating relative to the insertion hole. In this embodiment, both the shape of the insertion hole and the shape of the insertion segment 521 are regular square prisms. The non-circular cross-section of the regular square prism naturally restricts the rotational freedom between the insertion segment 521 and the insertion hole, thereby restricting the relative rotation of the insertion segment 521 relative to the insertion hole, thus preventing the detection roller 51 from tilting in the forward and backward direction and ensuring the stability of the operation of the correction structure 5. Furthermore, this structure does not require complex positioning (such as keyways and pins); assembly can be completed simply by aligning the edges, making the assembly efficiency of the L-shaped rod 52 high and easy to replace if damaged.

[0057] This utility model also proposes a conveyor belt, which includes a belt correction device 100. The specific structure of the belt correction device 100 is as described in the above embodiments. Since this conveyor belt adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The conveyor belt also includes a drive motor and a belt 200, and the drive motor is used to drive the belt 200 to move.

[0058] In one embodiment of this utility model, multiple belt correction devices 100 are arranged parallel to each other along the extension direction of the conveyor belt. Long-distance conveyor belts are prone to local deviation due to uneven tension, material distribution differences, or wear. Multiple belt correction devices 100 can monitor and adjust in sections, avoiding the lag of single-point correction. A single belt correction device 100 may cause the deviation to spread due to insufficient correction force or response delay, while multiple devices can intervene in time when the belt 200 deviates locally, preventing the problem from escalating (such as tearing of the belt 200 edge or material spillage).

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
