[0002] In the fully mechanized coal mining face, the infrared emission sensor and the infrared receiving sensor are one of the key detection equipment, mainly used for accurate positioning of the coal mining machine. Usually, the infrared emission sensor is installed on the body of the coal mining machine, and the infrared receiving sensor is installed on the hydraulic support. When the coal mining machine moves along the fully mechanized coal mining face, the infrared emission sensor continuously sends out infrared signals, and the infrared receiving sensor receives the signals and judges the real-time position of the coal mining machine through the signal strength and angle change. Based on this position information, the intelligent control system of the fully mechanized coal mining face can accurately control the actions of the hydraulic support such as following the machine, pulling the machine, collecting and protecting the side, and extending the protection side, to ensure the safety and efficiency of the coal mining operation. Therefore, the detection accuracy and reliability of the infrared sensor are crucial to the automatic operation of the fully mechanized coal mining face.

[0003] However, in the existing detection method, the test of the infrared sensor mainly depends on manual operation. Usually, the detection personnel need to visually select the positioning point, measure the action angle of the sensor with a protractor, and measure the transmission distance of the infrared signal with a steel tape, and finally calculate the working area of the sensor. However, this traditional manual measurement method has many problems:

[0004] 1. The action angle measurement error is large - since the protractor measurement is difficult to accurately align the zero point, and depends on visual reading, the angle measurement result is easily affected by human factors, and the error is large.

[0005] 2. The measured distance is not accurate - when measuring the distance between the sensor and the target with a steel tape, the position of the sensor is difficult to keep completely consistent every time, and the reading depends on visual observation, resulting in low repeatability and accuracy of the data.

[0006] 3. Manual operation is time-consuming and labor-intensive - the traditional measurement method requires at least two workers to cooperate in testing, which not only increases the labor cost, but also reduces the test efficiency, making it difficult to meet the needs of efficient detection.

[0007] Therefore, it is necessary to design a coal mine infrared transceiving sensor test frock that can effectively improve the accuracy and efficiency of measurement data. UTILITY MODEL CONTENT

A sensor clamping assembly 5 is installed above the clamping type moving platform 15. The assembly is made of silicone, which can effectively fix the infrared emitter 9, reduce vibration and external interference, and improve measurement accuracy. The sensor clamping assembly 5 is connected to the clamping type moving platform 15 by bolts, which facilitates disassembly and replacement of different models of infrared emitters 9.

[0033] The rear end of tool mounting seat 2 and mesa plate 3 is welded with dial assembly 1, which is semicircular in shape with a diameter equal to the length of the rear end of tool mounting seat 2. The upper surface of the dial assembly 1 is provided with an angle scale, with the radius line perpendicular to the diameter of the semicircle as the 0 degree reference line for angle measurement and positioning. The dial assembly 1 is fixedly connected to the left and right limit plates 12 and 11 and the telescopic measuring scale 6 through the locking mechanism 14. The left and right limit plates limit the movement range of the telescopic measuring scale 6 to prevent deviation during measurement. The length of the telescopic measuring scale 6 is between 1.23m and 5m, i.e. the length of the telescopic measuring scale 6 in the contracted state is 1.23m, and the fully extended length is 5m, which can adapt to different measurement requirements.

The length of the telescopic measuring ruler 6 can be freely adjusted within the range of 1.23m to 5m, therefore, it can adapt to the requirements of different measurement scenes. According to the actual situation, the measuring ruler is pulled out to the required length, and the locking mechanism 14 is used for fixation, to ensure that the test process will not slide or change in length. The top end of the telescopic measuring ruler 6 is provided with a receiving mounting seat 10, the operator needs to put the infrared receiver 8 into the receiving mounting seat 10, and fix it stably through the mounting hole, to ensure that the infrared signal can be accurately transmitted. At the same time, the bottom end of the measuring ruler 6 is provided with a folding support leg 13, which needs to be unfolded when in use, so that it contacts the ground, to enhance the overall stability of the measuring ruler, and prevent the data collection from being affected due to slight shaking.

[0037] After the above installation and adjustment are completed, the test of the infrared transceiver sensor can be carried out. During the test process, the infrared emitter 9 is started, at the same time, through the angle scale of the dial assembly 1, the length scale of the telescopic measuring ruler 6 and other data, the working area of the sensor is calculated, and whether the detection range meets the technical requirements is evaluated. After the test is completed, the locking mechanism 14 is loosened, the angle and length of the measuring ruler 6 are adjusted, to carry out the measurement of other angles or distances, to ensure the performance stability of the infrared transceiver sensor under different environments;
