Description
Technical field:
The utility model relates to the mining equiment proving installation, relates in particular to friction wheel hoist Maximum Loading Capacity difference proving installation.
Background technology:
Have following potential safety hazard in the friction wheel hoist operational process of mine: friction lining is progressively aging in the friction wheel hoist operational process of (1) mine, friction force or be called friction coefficient and progressively reduce and can not in time be tested can't determine whether friction lining can continue to use or change.(2) friction lining pockmark occurs and causes with the contact surface of steel rope and reduce in the mine friction wheel hoist operational process, and friction coefficient progressively reduces and can not in time test, and can't determine whether the grooving of friction lining carries out the car grooving.(3) in the mine friction wheel hoist operational process because steel rope quality and steel rope grease go wrong, cause that skidding appears in steel rope in the gig operational process, can not in time judge reason.Owing to above reason, have only mine friction wheel hoist friction force or claim friction coefficient to test timely and verify, could prevent and eliminate the potential safety hazard that exists.
The utility model content:
The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of friction wheel hoist Maximum Loading Capacity difference proving installation is provided, in time the Maximum Loading Capacity difference in the mine friction wheel hoist operation use is tested and verify, mine friction wheel hoist performance is carried out safety assessment, eliminate all kinds of accidents because of the friction coefficient reduction causes between friction wheel liner and the steel rope in the gig operational process.
Friction wheel hoist Maximum Loading Capacity difference proving installation described in the utility model, including steel rope, tension indicator A, pull action cylinder A, tension indicator B and pull action cylinder B forms, said steel rope be sleeved on the friction wheel of mine with the mine hoisting operation time steel rope steel rope identical in quality that uses, two ends at the steel rope of walking around friction wheel, one end is connected with tension indicator A, and the other end is connected with tension indicator B.The outer end of said tension indicator A is connected with pull action cylinder A, and the outer end of said tension indicator B is connected with pull action cylinder B.Pull action cylinder A is connected hydraulic control system by hydraulic circuit respectively again with pull action cylinder B, and said hydraulic control system includes pull action cylinder A, pull action cylinder B, by pass valve A, change-over valve A, compression indicator A, by pass valve C, compression indicator B, change-over valve B, by pass valve B, valve A and valve B again and forms.Pull action cylinder A is connected change-over valve A and change-over valve B by hydraulic oil pipeline respectively with pull action cylinder B.Change-over valve A connects by pass valve A and compression indicator A respectively by three-way pipe, and compression indicator A connects valve A by pipeline again.Change-over valve B connects by pass valve B and compression indicator B respectively by three-way pipe, and compression indicator B connects valve B by pipeline again.Valve A is connected by pass valve C by pipeline with the threeway form with valve B.
Friction wheel hoist Maximum Loading Capacity difference proving installation integral structure described in the utility model is simple, easy for operation, can be used at random or regularly the mine friction wheel being carried out test-based examination, to guarantee the friction force of mine friction wheel hoist, because have only mine friction wheel hoist friction force is tested and verified, could and eliminate the potential safety hazard prevention that exists, the safe operation of mine friction wheel hoist is played directive function.
