Abstract
Disclosed is a detection device for looseness of joint bolts of an adhesive tape elevator. The adhesive tape elevator comprises a plurality of sequentially connected adhesive tapes. The adjacent adhesive tapes are clamped via adhesive tape clamping plates, and fixed via bolts, nuts and gaskets cooperatively. The detection device comprises a plurality of extension pressure detection units which are respectively installed at connecting positions of the adjacent adhesive tapes, and a central processor. The extension pressure detection units are used for acquiring pressure of the bolts and the nuts at the connecting positions. Signal output ends of the extension pressure detection units are in wireless connection with the central processor via a communication module. The central processor is connected to a display for displaying detection data on pressure stain gages at different positions. According to the utility model, the degree of tightness of the bolts can be monitored in real time, maintenance personnel can examine the bots at belt joints in time, and serious economic losses due to that the tapes accidentally falling off are not timely maintained.
