Abstract
The invention discloses a monitoring device for hoisting of a steel wire rope. The monitoring device comprises a supporting rod, a first guide wheel and a second guide wheel, wherein the first guide rail and the second guide rail are arranged on the supporting rod; the supporting rod is provided with a speed-measuring wheel and a brake table and is further provided with a supporting frame; the supporting frame is provided with a telescopic device pointing to the brake table, and the output end of the telescopic device is connected with a downwards-pressing table corresponding to the brake table; the upper surface of the brake table and the lower surface of the downwards-pressing table are provided with wavy protrusions corresponding to one another. In this way, the monitoring device for hoisting of the steel wire rope has the advantages that the speed-measuring wheel is used for monitoring the steel wire rope passing through the first guide wheel and the second guide wheel, a controller is triggered once the speed of the steel wire rope exceeds the normal value, and then the downwards-pressing table descends rapidly to be combined with the brake table in a crossed mode so as to brake the steel wire rope and stop the steel wire rope from sliding downwards, so that the use security is improved.
