Beneficial effects of the present invention:In the use of the present invention, by between two steel wire clamping plates of steel wire penetrating, make steel wire
Rope utilizes linking arm or steel wire rope by tooth engaged and the pulley blocks of suspension hook positioned at moving jaw and the middle part of tooth engaged
Together, in hoisting heavy, when speed measuring device detects when rising or falling speed significant change of steel wire rope, test the speed consolidation dress
The signal transmission that will be detected is put to controller, controller is received after signal after processing is analyzed, and controller control is electronic
Push rod works, while controls alarm equipment alarm, and when electric pushrod work, the lower part of electric pushrod promotion moving jaw is to outward transport
It is dynamic, when moving jaw is moved to certain position, controller control electromagnetic lock work, and then locked moving jaw using electromagnetic lock
Fixed, in wire rope breaking, under the action of weight, the speed that pulley blocks decline is more than the speed of the device, therefore, pulley
Group is increasing with the spacing of the device, when the spacing of pulley blocks and the device increases to a certain degree, pulley blocks drop-down occlusion
Tooth, and then by the inwardly movement of the inner of tooth engaged, so as to fulfill using the interaction of tooth engaged and moving jaw by steel wire rope
Locked, so as to effectively avoid the generation of fall event, the present invention is with performance height rational in infrastructure, easy to use, safe, fortune
The advantages of row cost is low.
