Embodiment Construction
[0019] figure 1 is a schematic diagram of the structure of the present invention;
[0020] As shown in the figure: The device for detecting the tightness of the fasteners of the mine flameproof casing in this embodiment includes a follower component connected to the fastener and at least two sets of signal components used in cooperation with the follower component. The follow-up components move as the fasteners are loosened to trigger the signal components in turn. combine figure 1 As shown, the explosion-proof casing includes a casing 8 and a cover plate 9 covering the open end of the casing. The casing and the cover plate are fastened and connected by screws 10. The screws here are fasteners. Of course, bolts can also be used. The fastener realizes the connection, which will not be described in detail; the follower component is connected to the end of the screw, and the follower component can be connected to the head or screw end of the screw based on the connection form o...

The invention discloses a device for detecting the tightening state of a mine flameproof casing fastener, which comprises a follower component connected to the fastener and at least two sets of signal components used in cooperation with the follower component. The movement of the assembly as the fastener loosens in turn triggers the signal assembly. The invention has the advantages of simple structure, small volume, easy arrangement, low cost and simple realization method, and is suitable for the simultaneous detection of multiple locking screws of the explosion-proof casing. The hidden danger provides a detection method to ensure the electrical safety of the underground explosion-proof equipment.
Description
technical field [0001] The invention relates to the technical field of explosion-proof safety detection of explosion-proof equipment, in particular to a device for detecting the tightness of fasteners of explosion-proof casings for mines. Background technique [0002] For the underground working environment of coal mines, the explosion-proof casing of explosion-proof equipment needs to be fastened with fasteners such as bolts or screws. At present, the detection methods of the tightness of the fasteners of the explosion-proof casing are usually laser ranging detection method and image processing detection method. , the method of using laser ranging method and image processing method to determine the tightness of fasteners is complicated and costly, and is not suitable for detecting the tightness of fasteners in underground flameproof enclosures. [0003] Therefore, in order to solve the above problems, there is a need for a device for detecting the tightness of a mine flamep...
