Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a convenient testing device for temperature sensors in belt conveyors. Background Technology

[0002] According to the "Coal Mine Safety Regulations," belt conveyors must be equipped with six major protective devices, which must be sensitive and reliable, and the sensors must be tested regularly. Among these, the temperature sensor on the belt drive drum is a crucial protective device, effectively preventing fires caused by belt slippage. Temperature sensor failure is a major hidden danger affecting coal mine safety, potentially leading to mine shutdowns and even closure. The temperature sensor must be directly facing the drive drum surface, no more than 10mm away. Given this confined space, traditional testing methods require personnel to climb under the drive drum or inside the belt to test the sensor, posing a significant safety risk. If the belt malfunctions or rotates, it poses a serious threat to personnel's lives. Each test requires three people: one to monitor the start / stop operation, one to climb under the belt, and one to provide the medium, resulting in low efficiency.

[0003] Utility model patent CN 221324060 U discloses a temperature protection installation device for belt conveyors. By setting a fixed frame, and installing a movable push-pull frame and limiting block on the fixed frame, the temperature sensor on the push-pull frame can be moved to the outside of the frame, allowing for disassembly and maintenance. However, because this device lacks a temperature sensor position adjustment function, inaccurate measurement data is prone to occur under conditions such as changes in material characteristics, equipment wear and tear, and changes in ambient temperature. For example, belt rollers wear during use. Although the initial installation position may meet the standards, as the equipment operates, the rubber coating thins, causing the distance between the temperature sensor and the roller surface to increase, failing to meet temperature protection installation standards. This is deemed a major hidden danger by inspectors, leading to mine shutdown for rectification. Furthermore, because the required distance between the temperature sensor and the roller surface is extremely small, errors in the installation of the support pipe may also lead to inaccurate temperature sensor measurement data. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a convenient testing device for temperature sensors on conveyor belts. The temperature sensor can be pulled to the outside of the conveyor frame through a side opening on the walkway side, allowing for testing with a medium. This eliminates the need for personnel to climb inside the conveyor belt, simplifying operation and eliminating safety risks. Furthermore, this device allows adjustment of the relative angle and position of the temperature sensor on the conveyor belt roller surface, ensuring accurate measurement data.

[0005] This utility model is implemented as follows: A convenient testing device for a temperature sensor of a belt conveyor includes a temperature sensor, a supporting slide tube, a slide pipe, an adjustable mounting plate, and a pull rod; the supporting slide tube is a steel pipe with a slide track on its surface, and the supporting slide tube is used to fix it to the frame of the belt conveyor; the adjustable mounting plate is connected to the surface of the slide pipe, the slide pipe is placed inside the supporting slide tube, and the adjustable mounting plate is located inside the slide track of the supporting slide tube and can move along the slide track; the adjustable mounting plate is provided with a strip-shaped hole for fixing and adjusting the position of the temperature sensor, the temperature sensor is installed on the adjustable mounting plate, and a pull rod is connected to one side of the adjustable mounting plate.

[0006] Furthermore, the supporting slide tube is fixed to the frame of the belt conveyor by locking bolts.

[0017] Example 1:

[0018] A convenient testing device for temperature sensors in conveyor belts, such as... Figures 1-4 As shown, the system includes a temperature sensor 2, a support slide tube 5, a slide tube 4, an adjustable mounting plate 3, and a pull rod 1. The support slide tube 5 is a steel pipe with a slide track 7 cut out on its surface, and it is used to fix the belt conveyor 9 to the frame. The slide tube 4 is connected to the adjustable mounting plate 3, and the slide tube 4 is placed inside the support slide tube 5. The adjustable mounting plate 3 is located inside the slide track 7 of the support slide tube 5 and can move along the slide track 7. The adjustable mounting plate 3 is provided with a strip-shaped hole for fixing and adjusting the position of the temperature sensor 2. The temperature sensor 2 is installed on the adjustable mounting plate 3, and the pull rod 1 is connected to one side of the adjustable mounting plate 3. In use, the temperature sensor 2 faces the roller of the belt conveyor 9, and the operator adjusts the position of the temperature sensor 2 from the side of the roller using the pull rod 1.

[0019] This device uses a DN25 steel pipe to form the support slide tube 5, with a slide 7 cut into its surface. The length and position of the slide 7 are determined by the location where the temperature sensor 2 is installed. The support slide tube 5 is fixed to the frame of the belt conveyor 9. Inside, a DN16 steel pipe is welded to an adjustable mounting plate 3 for mounting the temperature sensor 2. The adjustable mounting plate 3 passes through the slide 7, allowing the internal steel pipe to slide within the support slide tube. When the temperature sensor 2 is working, pushing the pull rod 1 pushes the adjustable mounting plate 3 to the end of the slide 7, where it is stopped by the slide 7, thus placing the temperature sensor 2 in the correct working position. For testing, the pull rod 1 is pulled through the side opening on the side of the belt conveyor frame beam to pull the temperature sensor 2 to one side of the frame. A test medium is used for testing. After the test, the temperature sensor 2 is pushed back to the correct working position. The adjustable mounting plate 3 has a slotted hole. The temperature sensor 2 is connected to the adjustable mounting plate 3 via bolts 8. Adjusting the bolts 8 changes the position of the temperature sensor 2 relative to the adjustable mounting plate 3. Since the installation position of the temperature sensor 2 directly affects the accuracy of the measurement data, adjusting the relative position of the temperature sensor 2 can make the measurement data more accurate.

[0020] Example 2:

[0021] This embodiment is another implementation of embodiment 1, the difference being that the supporting slide tube 5 and the slide tube 4 are made of square steel tubes.

[0022] Example 3:

[0023] This embodiment is another implementation of embodiment 1. The supporting slide tube 5 is fixed to the frame of the belt conveyor 9 by two telescopic locking bolts 6 processed at both ends of the steel pipe. The angle of the supporting slide tube 5 relative to the belt conveyor 9 can be adjusted by the locking bolts 6. This method can ensure that the temperature sensor 2 is in the correct measurement position and ensure the accuracy of the measurement data.

[0024] A convenient testing device for temperature sensors in conveyor belts allows for quick and easy adjustment of the temperature sensor's position, eliminating the need for workers to operate in hazardous areas and effectively ensuring personnel safety. It also significantly improves the reliability and stability of the system. This device can be used for convenient testing to determine the temperature sensor's location or directly as a temperature sensor positioning device.
