Technical Field
[0001] This utility model belongs to the field of mining testing equipment, and in particular relates to a mining conveyor belt misalignment detection device. Background Technology
[0002] Belt conveyors are common material conveying equipment in mines. Due to their advantages such as safe operation, convenient use, low maintenance costs, and high efficiency, they are widely used in the conveying of various solid lumps and powders.
[0003] Belt misalignment is a common malfunction in material conveying via belt conveyors. When a belt misaligns, not only is conveying efficiency affected, but it can also cause material spillage, abnormal wear on the belt rollers and belt edges, and in severe cases, shutdown of the operating system, creating greater safety hazards. Therefore, those skilled in the art typically install misalignment detection devices on the belt edges to determine the belt's direction during operation and to make timely adjustments and maintenance.
[0004] However, the existing detection device cannot be adjusted in position after installation. The staff cannot adjust the posture of the detection device according to the inclination angle of the belt edge, nor can they flexibly adjust the relative position of the detection device and the belt according to the width of the belt, so the convenience of use is poor.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0007] A belt misalignment detection device for mining applications includes: a mounting base, a connecting base, and a misalignment sensor. The mounting base includes a support plate and two limiting plates, both of which are vertically mounted on the bottom surface of the support plate, forming a receiving channel between them. Each limiting plate has a receiving hole and an arc-shaped guide cut, with the center of the arc of the guide cut coinciding with the center of the receiving hole. A rotating shaft is located inside the receiving hole, and a slidable connecting shaft is located inside the arc-shaped guide cut. The connecting base includes a connecting plate and a connecting strip. The connecting plate is located at one end of the connecting strip, and the misalignment sensor is mounted on the connecting plate in an adjustable position. The connecting strip is placed inside the receiving channel. The connecting strip has a first elongated hole for receiving the rotating shaft and a second elongated hole for receiving the connecting shaft, with the length direction of the first elongated hole parallel to the length direction of the second elongated hole. At the end of the connecting strip away from the connecting plate, a threaded hole communicating with the second elongated hole is also provided. An adjusting screw is located inside the threaded hole, with the axis of the adjusting screw perpendicular to the connecting shaft, and the adjusting screw is rotatably connected to the connecting shaft.
[0008] Furthermore, the end of the adjusting screw is provided with a splicing shaft, and a detachable limiting plate is provided on the end face of the splicing shaft away from the adjusting screw. The outer diameter of the splicing shaft is smaller than the outer diameter of the adjusting screw, and the outer diameter of the limiting plate is larger than the outer diameter of the splicing shaft. A splicing hole for accommodating the splicing shaft is also provided on the side wall of the connecting shaft. The inner diameter of the splicing hole is equal to the outer diameter of the splicing shaft, and the adjusting screw and the limiting plate are located on both sides of the connecting shaft.
[0009] Furthermore, the limiting plate is provided with splicing studs, and the end face of the splicing shaft is provided with splicing screw holes for accommodating the splicing studs.
[0010] Furthermore, the side wall of the deviation sensor is provided with a connecting ear, and an assembly bolt is provided inside the connecting ear; the connecting plate is provided with an elongated mounting hole for accommodating the assembly bolt, and the length direction of the elongated mounting hole is perpendicular to the length direction of the first elongated hole.
[0011] Furthermore, the two ends of the connecting shaft are respectively provided with a blocking plate and a locking screw.

[0014] Furthermore, the end of the adjusting screw away from the splicing shaft is provided with an operating screw head, and anti-slip stripes are provided on the outer side wall of the operating screw head.
[0015] Compared with existing technologies, the mining conveyor belt misalignment detection device of this utility model has the following advantages:
[0016] (1) The mining belt misalignment detection device of this utility model can install the misalignment sensor onto the belt conveyor through the cooperation of the mounting base and the connecting base. Since the mounting base has a receiving hole and an arc-shaped guide cutout on the limiting plate, and the connecting base is connected to the mounting base through the rotating shaft and the connecting shaft, after assembly, the operator can drive the connecting base to rotate around the rotating shaft to adjust the tilt posture of the misalignment sensor so that the misalignment sensor can contact the edge of the belt.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] A mining conveyor belt misalignment detection device, the structure of which can be made of Figures 1-7The following is an illustration. In this embodiment, the mining belt misalignment detection device includes: a mounting base, a connecting base, and a misalignment sensor 8. The mounting base is used to assemble the device on the frame of the belt conveyor, and the connecting base is used to connect the misalignment sensor 8 to the mounting base, and to facilitate the adjustment of the attitude and position of the misalignment sensor 8 by the operator according to the actual condition of the belt after assembly.
[0033] Specifically, such as Figure 5 As shown, the mounting base includes a support plate 1 and two limiting plates 2. Both limiting plates 2 are vertically disposed on the bottom surface of the support plate 1, forming a receiving channel between them. Each limiting plate 2 has a receiving hole 21 and an arc-shaped guide cutout 22, wherein the center of the arc of the arc-shaped guide cutout 22 coincides with the center of the receiving hole 21. A rotating shaft 3 is disposed inside the receiving hole 21, and a slidable connecting shaft 4 is disposed inside the arc-shaped guide cutout 22. The connecting base includes a connecting plate 5 and a connecting strip 6. The connecting plate 5 is disposed at one end of the connecting strip 6. The connecting strip 6 has a first elongated hole 61 and a second elongated hole 62, and the length direction of the first elongated hole 61 is parallel to the length direction of the second elongated hole 62.
[0034] During assembly, the operator should first install the bearing plate 1 onto the belt conveyor frame using bolts, and then adjust the position of the misalignment sensor 8 onto the connecting plate 5. Next, insert the connecting strip 6 into the receiving channel, and ensure that the rotating shaft 3 and the connecting shaft 4 are respectively inserted into the first elongated hole 61 and the second elongated hole 62 to complete the assembly of the device. After assembly, the operator can adjust the posture of the misalignment sensor 8 by rotating the connecting piece around the rotating shaft 3 according to the actual posture of the belt. Figure 1 and Figure 2 This is a schematic diagram of the device with the first elongated hole 61 and the support plate 1 in a parallel position. Figure 3 and Figure 4 This is a schematic diagram of the device in an angled posture between the first elongated hole 61 and the support plate 1, which can be used to facilitate understanding of the actual use of the device, so as to detect the position of the belt edge by the contact rod on the belt misalignment sensor 8 and determine whether belt misalignment has occurred.
[0035] Optionally, to prevent abnormal rotation of the connector during actual operation, both ends of the connecting shaft 4 can be equipped with a blocking plate 42 and a locking screw 43, respectively. The outer diameter of the blocking plate should be larger than the outer diameter of the connecting shaft 4, and a locking sleeve 9 should be provided on the locking screw 43. During assembly, the blocking plate 42 can be used to limit one end of the connecting shaft 4, and the locking screw 43 should extend outward from the mounting base along the arc-shaped guide cut 22, with the locking sleeve 9 installed on the portion of the locking screw 43 that protrudes from the mounting base. When the orientation of the connector meets the actual usage requirements, the operator can tighten the locking sleeve 9, thereby limiting the rotation of the connector through the cooperation of the blocking plate 42 and the locking sleeve 9.
[0036] In addition, to further improve the limiting effect of the locking nut 9, an anti-slip ring 91 can be provided at the end of the locking nut 9 near the limiting plate 2, thereby increasing the frictional resistance between the locking nut 9 and the limiting plate 2 by means of the anti-slip ring 91.
[0037] As an optional implementation of this embodiment, in order to increase the rotation range of the connector, the bearing plate 1 may also be provided with an avoidance cut 11 connected to the receiving channel, so that the end of the connecting strip 6 with the connecting plate 5 can rotate upward along the avoidance cut 11, which facilitates the detection of the belt edge with a large inclination angle.
[0038] It should be noted that the belt misalignment sensor 8 described in this embodiment can be a GEJ30 intrinsically safe mining belt misalignment sensor. During operation, under normal conditions, the edge of the belt will not contact the contact rod, therefore the two terminals inside the belt misalignment sensor 8 are not conductive. When the edge of the belt contacts the contact rod due to misalignment and pushes the contact rod to a preset deflection angle, the two terminals inside the belt misalignment sensor 8 will connect, thereby sending a signal to the host computer to alert the operator that the belt is misaligned. Since the specific structure and working principle of the belt misalignment sensor 8 are well known and not part of the core invention content of this application, they will not be described in detail herein.
[0039] In actual work, due to the differences in the width of different belts, in order to adapt to the belt misalignment detection work of belts of different widths, such as... Figure 6As shown, in this embodiment, the end of the connecting strip 6 away from the connecting plate 5 is also provided with a threaded hole 63 that communicates with the second elongated hole 62. An adjusting screw 7 should be provided inside the threaded hole 63, and the axis of the adjusting screw 7 is perpendicular to the connecting shaft 4. The adjusting screw 7 is rotatably connected to the connecting shaft 4. When the width specification of the belt changes, the distance between the belt misalignment sensor 8 and the belt needs to be adjusted. At this time, the operator can drive the adjusting screw 7 to rotate. Since the rotating shaft 3 and the connecting shaft 4 are respectively restricted by the receiving hole 21 and the arc-shaped guide cut 22, when the adjusting screw 7 rotates, the threaded connection between the adjusting screw 7 and the threaded hole 63 will drive the connecting piece to slide along the length direction of the second elongated hole 62, thereby changing the distance between the belt misalignment sensor 8 and the belt.
[0040] Optionally, to achieve a rotatable connection between the adjusting screw 7 and the connecting shaft 4, such as... Figure 7 As shown, in this embodiment, a splicing shaft 71 may be provided at the end of the adjusting screw 7, and a detachable limiting plate 72 may be provided on the end face of the splicing shaft 71 away from the adjusting screw 7. The outer diameter of the splicing shaft 71 should be smaller than the outer diameter of the adjusting screw 7, and the outer diameter of the limiting plate 72 should be larger than the outer diameter of the splicing shaft 71. Correspondingly, a splicing hole 41 for accommodating the splicing shaft 71 may also be provided on the side wall of the connecting shaft 4, and the inner diameter of the splicing hole 41 should be equal to the outer diameter of the splicing shaft 71. During assembly, the operator should first insert the splicing shaft 71 into the splicing hole 41, and then install the limiting plate 72 onto the splicing shaft 71, so that the adjusting screw 7 and the limiting plate 72 are located on both sides of the connecting shaft 4, preventing the adjusting screw 7 from separating from the connecting shaft 4.
[0041] In addition, to facilitate the operation of the adjusting screw 7 by the staff, an operating screw head 73 can be provided at the end of the adjusting screw 7 away from the splicing shaft 71, and anti-slip stripes can be provided on the outer wall of the operating screw head 73 so that the staff can input the rotational torque to the adjusting screw 7 through the operating screw head 73.
[0042] As another optional implementation of this embodiment, the limiting plate 72 may be provided with a splicing stud 721, and the end face of the splicing shaft 71 may be provided with a splicing screw hole 711 for accommodating the splicing stud 721, thereby realizing a detachable connection between the limiting plate 72 and the splicing shaft 71 by means of a threaded connection.
[0043] Furthermore, since the belt needs to be installed at different heights inside the frame under different working conditions, a connecting lug 81 can be provided on the side wall of the belt misalignment sensor 8 to improve the adaptability of this device to belts at different installation heights. An assembly bolt 82 is provided inside the connecting lug 81. Correspondingly, an elongated mounting hole 51 for accommodating the assembly bolt 82 is provided on the connecting plate 5, and the length direction of the elongated mounting hole 51 is perpendicular to the length direction of the first elongated hole 61. When the installation height of the belt changes, the operator can slide the assembly bolt 82 along the elongated mounting hole 51 to adjust the installation position of the belt misalignment sensor 8 on the connecting plate 5, facilitating actual belt detection.
[0044] The effects of the above solution are explained below:
[0045] This embodiment provides a belt misalignment detection device for mining applications. It can adjust the tilt of the misalignment sensor by rotating the connector, adapt to belts of different widths by sliding the connector, and adapt to belts of different installation heights by adjusting the position of the misalignment sensor on the connecting plate. This allows workers to flexibly adjust the actual position of the misalignment sensor after completing the assembly work, improving the ease of operation in actual use.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
