Description

Technical Field

[0001] This utility model belongs to the field of measurement and identification technology of optical tile detectors for coal mines, and particularly relates to a drop device in optical tile identification, specifically a self-made optical tile dropper. Background Technology

[0002] In mine gas inspection work, optical gas detectors are currently the most commonly used inspection instruments underground. An optical gas detector is composed of various screws of different types assembling components together. During maintenance, components are frequently replaced, which raises the question of whether the assembly is secure. If the assembly is loose, the instrument will not withstand impacts, affecting gas value measurement and creating a safety hazard for gas inspection work.

[0003] According to the metrological verification regulations, the repair, disassembly, cleaning, and replacement of major components have a significant impact on the metrological performance of optical tile detectors. Subsequent verification requires a drop test, which requires the optical tile detector to be dropped from a height of 100mm onto a 50mm thick wooden board. Then, the movement of the interference fringes of the instrument is observed. If the movement of the interference fringes of the (0-10)%CH4 detector is greater than 0.2%CH4, or the movement of the interference fringes of the (0-100)%CH4 detector is greater than 2%CH4, the instrument is considered unqualified. However, there is currently no suitable device for drop testing. Summary of the Invention

[0004] This invention addresses the problem of how to conveniently conduct drop tests on optical tile detectors after repair and component replacement by providing a self-made optical tile drop tester.

[0005] This utility model is achieved using the following technical solution: a self-made optical tile dropper, comprising an operating handle, a base, a channel steel track, a wooden pad, and a placement platform; a vertical channel steel track is provided on the base, and each of the two wing plates of the channel steel track is connected to a limiting plate parallel to the web plate, with the two limiting plates facing each other; the wooden pad is placed on the base and located at the bottom of the channel steel track; a notch is opened in the web plate of the channel steel track; the operating handle is hinged to the back of the web plate of the channel steel track; the placement platform of the optical tile detector is connected to the operating handle; the placement platform extends into the channel steel track from the notch in the web plate.

[0006] The optical tile detector to be tested is placed in the channel steel track and placed on the placement platform. Then, the operating handle is lifted, and the operating handle moves the placement platform back to the outside of the channel steel track, so that the optical tile detector on the placement platform falls smoothly down the channel steel track onto the wooden pad, thus completing the drop test.

[0007] The aforementioned homemade light tile dropper has a wooden pad thickness of 50mm and a distance of 100mm between the top surface of the platform and the top surface of the wooden pad.

[0008] The present invention has the following advantages over the prior art: by applying this device, the accuracy of the drop test height of the instrument can be guaranteed, and the instrument can be dropped under uniform force, which greatly improves the pass rate of the instrument.

[0014] Homemade light tile drop device, such as Figures 1-4 As shown, it includes an operating handle 1, a base 2, a channel steel rail 3, a wooden pad 4, and a placement platform 5. The base 2 is a block structure with the channel steel rail 3 welded on it. Each of the two wing plates of the channel steel rail 3 is connected to a limiting plate parallel to the web plate. The two limiting plates are set facing each other. The wooden pad 4 is placed on the base 2 and located at the bottom of the channel steel rail 3. The thickness of the wooden pad 4 is 50mm. There is a notch in the web plate of the channel steel rail 3. The operating handle 1 is hinged to the back of the web plate of the channel steel rail 3. The placement platform 5 of the optical tile detector is connected to the operating handle 1. The placement platform 5 extends into the channel steel rail 3 from the notch in the web plate. The distance between the top surface of the placement platform 5 and the top surface of the wooden pad 4 is 100mm.

[0015] During the drop test, the optical tile detector to be tested is placed inside the channel steel track 3 and placed on the placement platform 5. Then, the operating handle 1 is lifted, and the operating handle 1 moves the placement platform 5 back to the outside of the channel steel track 3, so that the optical tile detector on the placement platform 5 falls smoothly along the channel steel track 3 onto the 50mm thick wooden pad 4, thus completing the drop test.
