[0026] The above-mentioned sliding mechanism includes a second mounting frame 13, which is fixedly mounted on the slider of the corresponding rodless cylinder 12, and a second bidirectional screw 14 is rotatably mounted in the second mounting frame 13, and two second sliding plates 15 are threadedly mounted on the second bidirectional screw 14, and two second horizontal bars are fixedly mounted in the second mounting frame 13, the two second horizontal bars pass through the two second sliding plates 15 and are slidably connected to the two second sliding plates 15, and a push rod 16 is fixedly mounted on the bottom of the two second sliding plates 15, and a second servo motor is fixedly mounted on the outer wall of one side of the second mounting frame 13, and its output shaft is fixedly connected to one end of the second bidirectional screw 14.

[0027] In this method, in order to be able to adjust the height position of the deviation sensor 11 according to actual needs, ring sleeves are fixedly provided on the two hollow tubes 7, and T-shaped ring grooves are opened on the two ring sleeves. Two T-rods are slidably installed in the two T-shaped ring grooves, and a rotating seat 9 is threadedly provided on the two one-way screws 8. The bottom ends of the corresponding two T-rods are fixedly connected to the corresponding rotating seats 9, and the top ends of the two one-way screws 8 are fixedly installed with a locking rod. The two locking rods pass through the corresponding hollow tubes 7 and are slidably connected to the corresponding hollow tubes 7. By rotating the rotating seat 9, the one-way screw 8 can be adjusted to rise and fall linearly.

[0028] In this method, in order to be able to adjust the test position of the deviation sensor 11 without moving the I-beam support platform 1, a plurality of adjustment slots 17 are opened on the top of the I-beam support platform 1, and a threaded rod 18 is rotatably installed on the top of the transverse slide 2, and a connecting bar 19 is threadedly installed on the threaded rod 18.

[0029] In this embodiment, in order to ensure that there is no interference between the first sliding plate 6 and the connecting plate 4, two sliding openings are provided on the connecting plate 4, and the two first sliding plates 6 pass through the corresponding sliding openings and contact the inner walls of the corresponding sliding openings.

[0030] The working principle of the belt conveyor protection sensor test device provided by the utility model is as follows:

[0031] In this device, a tape conveyor used only for testing needs to be prepared in advance and placed in the designated test site.

[0032] When it is necessary to test the deviation sensor 11, first fix the two deviation sensors 11 on the two fixing plates 10 respectively, then insert the I-beam support platform 1 from one end of the test belt conveyor, and then adjust the position of the fixing plate 10 according to the belt height of the belt conveyor.

[0033] During adjustment, first rotate one of the rotating seats 9. Under the limit of the positioning rod, the corresponding one-way screw 8 begins to descend, thereby causing the corresponding fixed plate 10 and the deviation sensor 11 to descend. After the deviation sensor 11 descends to the specified test height, rotate the other rotating seat 9 in the same way, and finally adjust both deviation sensors 11 to the specified height. Then start the first servo motor in the forward direction, and its output shaft drives the first two-way screw 5 to rotate, so that the two first sliding plates 6 move toward each other, and finally adjust the two deviation sensors 11 to the specified position on the longitudinal level.

[0034] Subsequently, the positions of the four push rods 16 are adjusted according to the width of the tape on the tape machine. During the adjustment, the two second servo motors are started to make the corresponding two second sliding plates 15 approach each other until the distance between the corresponding two push rods 16 is close to the tape, and then the second servo motors are turned off. Then, the sliders on the two rodless cylinders 12 are started to move in the same direction. When the two push rods 16 corresponding to one side touch the tape, they will push the tape, thereby simulating the deviation of the tape. If the deviation sensor 11 on the corresponding side does not malfunction, the deviation can be detected, thereby sending a signal. If a malfunction occurs, no signal will be sent. At this point, the quality of the deviation sensor 11 can be judged.

[0035] Afterwards, in the same way, start the sliders on the two rodless cylinders 12 to move in the opposite direction. When the two push rods 16 on the other side contact the tape, the same experience as above will occur, so that the quality of the other deviation sensor 11 can be judged.

[0036] At this point, the tests on the two deviation sensors 11 are completed. After all the tests are completed, the good deviation sensors 11 can be installed on the belt conveyor for use.

[0037] Moreover, during the above-mentioned test process, if you want to test different parts of the tape, you can first rotate the threaded rod 18 counterclockwise so that the connecting bar 19 and the two positioning heads 21 rise and move out of the corresponding adjustment grooves 17, then move the horizontal slide 2. When it moves to the specified position, rotate the threaded rod 18 clockwise again to bring the two positioning heads 21 into the corresponding two adjustment grooves 17.

[0038] Compared with the related art, the tape conveyor protection sensor test device provided by the utility model has the following beneficial effects:

[0039] The present utility model provides a test device for a belt conveyor protection sensor. By means of the four push rods 16, the device can cooperate with a belt conveyor specially used for testing, so that the deviation situation can be simulated in a special test site to test the deviation sensor 11. There is no need to test directly on the underground belt conveyor, so that it is not restricted by space and is convenient for people to test the deviation sensor 11. In addition, during the test, the test position can be flexibly adjusted, so that the deviation sensor 11 can be tested more comprehensively.
