Description

technical field

[0001] The invention relates to the technical field of measuring equipment, in particular to a device for measuring the diameter difference of a capstan pulley rope groove of a hoist. Background technique

[0002] For the multi-rope friction hoist in operation, the tension difference of the hoisting ropes should be checked once a week. If the difference in the rebound time of the tension of each rope exceeds 10%, the tension difference should be adjusted. The diameter difference of each rope groove of the capstan or guide wheel is an important factor affecting the tension difference of the hoisting rope. The "Safety Regulations for Metal and Nonmetal Mine" clearly stipulates that the friction liner of the capstan wheel and the guide wheel should be turned in time according to the wear condition, and the diameter difference of the rope groove should not be greater than 0.8mm.

[0003] The diameter difference of the capstan or guide wheel of the multi-rope fri...
