Description

Technical Field

[0001] This utility model relates to the field of conveyor tube twist detection technology, specifically, to a tube twist detection device for a tubular belt conveyor. Background Technology

[0002] The tubular belt conveyor twist detection device is a device that detects the twisted edge position of the tubular belt during the operation of the tubular belt conveyor. The tubular belt conveyor is a new type of belt conveyor developed on the basis of the ordinary belt conveyor. It uses special conveyor belts guided by idlers.

[0003] Chinese patent discloses a torsion detection device for a tubular belt conveyor, publication number CN220702229U. It includes a base, on which a detection frame is installed. The detection frame has a slide rail inside and four corner plates in the middle of the detection frame to remind the operator to adjust the edge position and prevent the conveyor belt from tearing. This makes the detection device highly accurate and has a wide detection range, and can detect the position of the edge of the torsion tube body in real time.

[0004] The existing technology also has the following drawbacks: When the tubular belt conveyor is working, it transports materials by winding the conveyor belt. However, the transmission length is too long, and the conveyor belt is not made of a high-strength and non-deformable material. When the winding operation is performed, there is a possibility that some parts of the connection at the top may not be properly sealed, which can easily lead to leakage when transporting materials and affect the overall working effect.

[0023] like Figures 1-4 As shown, it illustrates a torsion detection device for a tubular belt conveyor according to one embodiment of the present invention.

[0024] This embodiment provides a torsion detection device for a tubular belt conveyor. Through the cooperation of the connecting part 201 and the detection part 202, a detection sensor 2024 can be quickly installed on the top surface of the conveyor belt when the tubular belt conveyor is conveying materials. When the conveyor belt 2013 is moving, the device can perform real-time sealing detection on each position of the conveyor belt 2013 to detect whether there is a leakage problem at its connection and promptly set a location alarm to ensure that subsequent conveying will not have leakage affecting the transportation effect.

[0025] In some examples, a torsion detection device for a tubular belt conveyor includes a main body unit 100, a detection unit 200, and a limiting unit 300.

[0026] The main unit 100 includes a frame 101, and multiple protective plates 102 are evenly fixedly arranged on the front and rear end faces of the multiple frames 101. A fixing frame 103 is fixedly arranged on the outer side of the front protective plate 102. The detection unit 200, which is located inside the main body unit 100, includes a connecting part 201 and a detection part 202 located on its top surface. The detection unit 200 is used to detect the twist of the conveyor tube. The limiting unit 300, which is provided on the side of the upright 101, includes an adjustment part 301 and a limiting part 302 located on its side. The limiting unit 300 is used to limit the conveyor belt 2013.

[0027] In use, the material is transferred through the connecting part 201. The detection part 202 is installed above the top plate 2011 and makes it contact the top surface of the conveyor belt 2013 to perform a quick connection seal test. The adjusting part 301 works with the limiting part 302 to limit the connecting part 201, so as to quickly realize the material transfer.

[0028] For example, such as Figure 1 As shown, the connecting part 201 includes a top plate 2011 fixedly connected to the inner sides of the two uprights 101, a bottom plate 2012 fixedly provided on the bottom surface of the top plate 2011 and the inner sides of the two uprights 101, and a conveyor belt 2013 slidably connected to the inner walls of the top plate 2011 and the bottom plate 2012.

[0029] For example, such as Figure 1 and Figure 2As shown, the detection unit 202 includes a motor 2021 fixedly connected to the right side of the front-end fixed frame 103. The left end of the output rod of the motor 2021 extends through the right side of the fixed frame 103 into the interior of the fixed frame 103 and is fixedly connected to a transmission roller 2022. The surface of the transmission roller 2022 is rotatably connected to the inner wall of the fixed frame 103. The surfaces of the two transmission rollers 2022 are drive-connected to the inner wall of the transmission belt 2013. A connecting plate 2023 is fixedly installed on the top surface of the front-end top plate 2011. A detection sensor 2024 is fixedly installed on the bottom surface of the connecting plate 2023. The inner wall of the detection sensor 2024 and the top surface of the transmission belt 2013 are in sealed sliding contact. An alarm light is fixedly installed on the top surface of the detection sensor 2024.

[0030] When using the above structure, starting the motor 2021 causes the transmission roller 2022 to rotate. This, in conjunction with the rear transmission roller 2022, quickly drives the transmission belt 2013 for transport. The detection sensor 2024 is positioned and adjusted so that it is on the top surface of the transmission belt 2013 and in sealed contact with the connection points at both ends of the transmission belt 2013. After material is placed at one end, it is transported along with the transmission belt 2013. Simultaneously, the transmission belt 2013 moves, and the detection sensor 2024 quickly and in real-time performs sealing checks on the top surface of the rolled-up transmission belt 2013. If a sealing problem occurs, an alarm sounds immediately, and the transmission belt 2013 stops moving. The system then quickly positions the transmission belt 2013 for sealing checks and adjustments. It is worth noting that the alarm on the top surface of the detection sensor 2024 is connected to the power transmission signal of the motor 2021; an alarm will stop the power transmission of the motor 2021.

[0031] For example, such as Figure 2 As shown, the adjustment unit 301 includes multiple fixing plates 3011 fixedly connected to the back of the top plate 2011 and the bottom plate 2012. A hydraulic cylinder 3012 is fixedly installed on the inner wall of the multiple fixing plates 3011, and a sliding plate 3013 is fixedly installed on the other end of the output rod of the hydraulic cylinder 3012.

[0032] For example, such as Figure 2 and Figure 3 As shown, a bidirectional hydraulic cylinder 3014 is fixedly installed on the back of the top plate 2011 and the bottom plate 2012. The upper and lower ends of the two output rods of the bidirectional hydraulic cylinder 3014 are fixedly connected to the upper and lower ends of the other two slide plates 3013 respectively. The inner walls of the multiple slide plates 3013 are rotatably connected to the surfaces of the slide plates 2011 and the bottom plate 2012 respectively.

[0033] For example, such as Figure 3 As shown, the limiting part 302 includes a limiting roller 3021 fixedly connected to the side of the slide plate 3013, and multiple protective pads 3022 fixedly provided at the four ends of the inner walls of the top plate 2011 and the bottom plate 2012, with the surface of the conveyor belt 2013 abutting against the side of the protective pads 3022.

[0034] For example, such as Figure 3 and Figure 4 As shown, two edge-rolling frames 3023 are fixedly installed on the inner walls of the left and right ends of the protective plate 102, and the sides of the two edge-rolling frames 3023 are pressed and contacted with the surface of the conveyor belt 2013.

[0035] When in use, the hydraulic cylinders 3012 and 3014 are activated, causing the two slide plates 3013 to rotate along the rotating rods inside the top plate 2011 and bottom plate 2012. This causes multiple limiting rollers 3021 to limit the transmission of the conveyor belt 2013. Combined with the protective pads 3022, this effectively reduces the transmission friction loss of the conveyor belt 2013. At the same time, when the conveyor belt 2013 is moving, the edge-rolling frame 3023 can quickly roll the edge of the conveyor belt 2013, allowing it to be rolled into a cylindrical shape for transmission.

[0036] Working Principle: Starting motor 2021 causes conveyor roller 2022 to rotate. This, in conjunction with the rear conveyor roller 2022, rapidly drives conveyor belt 2013 for transport. Meanwhile, the detection sensor 2024 is positioned and adjusted so that it is on the top surface of conveyor belt 2013 and in sealed contact with the joints at both ends of conveyor belt 2013. After material is placed at one end, it is transported along with conveyor belt 2013. Simultaneously, conveyor belt 2013 is also moving. The detection sensor 2024 rapidly and in real-time monitors the seal of the rolled-up top surface of conveyor belt 2013. If a sealing problem occurs, an alarm sounds immediately, and conveyor belt 2013 is stopped. The system then quickly repositions and repositions conveyor belt 2013. During the sealing inspection and debugging, it is worth mentioning that the alarm on the top surface of the detection sensor 2024 is connected to the power transmission signal of the motor 2021. When the alarm is triggered, the power transmission of the motor 2021 will be stopped, and the hydraulic cylinder 3012 and the bidirectional hydraulic cylinder 3014 will be activated. This will cause the two slide plates 3013 to rotate along the rotating rod inside the top plate 2011 and the bottom plate 2012. This will cause the multiple limit rollers 3021 to limit the transmission of the conveyor belt 2013. Together with the protective pad 3022, this will effectively reduce the transmission friction loss of the conveyor belt 2013. At the same time, when the conveyor belt 2013 is moving, the edge-rolling frame 3023 can quickly roll the edge of the conveyor belt 2013 so that it can be rolled into a cylindrical shape for transmission.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
