Deep-well hoisting device state monitoring method disclosed in CN201710531454.5 is based on signal fused can be from hybrid monitoring signal
In separate fault-signal, monitor system running state.Meanwhile some scholars are by building various test bed testing lifting systems
Performance, the ultra-deep mine hoisting system testing stand as disclosed in Patent No. ZL 201410528414.1 are dragged using motor level
The mode dragged substitutes the operating condition of the vertical-lift under actual condition, simulates a variety of mine hoisting functions；Patent No.
Ultra-deep mine hoisting system Multi-functional analog test platform disclosed in ZL201610118998.4 can simulate to be surpassed under actual condition
Deep mine hoisting equips motion state, obtains hoisting device Specifeca tion speeification under fault condition；Patent No. ZL
Km deep-well winding hoisting churn friction system disclosed in 201410728399.5 can simulate different rotating speeds, accelerate
Churn friction duty under degree, impact velocity, specific contact pressure.The studies above is primarily present following problems: first, mainly

The different model mine shaft hoist system of manufacturer's production is unified before installing at the scene to check, and avoids the retest of large-scale manufacturing enterprise
Investment, promotes the manufacturing quality of small-sized manufacturing enterprise, and lifting system safety is ensured from source；Second, mainly for single type
Number lifting system detected, can not effectively adapt to different drum diameters, reel encloses cornerite, wirerope radical, wirerope
The lifting system of spacing；Third lacks load detection in a pre-installation, to main shaft device load-carrying properties, liner non-skid property, braking
Lock braking ability can not accurate evaluation；4th, in-service mine is detected, main shaft device can not be efficiently used without negative
Characteristic parameter variation under carrying and being heavily loaded, and this is important feature the defects of diagnosing main shaft device abnormal deformation, crackle, simultaneously
Can not the pernicious operating condition such as analog card tank, twice loading, and the latter be judge main shaft device, friction lining, braking system can
Bear the important references of extreme operating condition.Thus, it is necessary to a kind of vertical shaft hoisting joint debugging test device is studied, it can be to different model
The main shaft device of lifting system, liner and braking system carry out joint debugging test, the nominal situations such as simulation no-load, heavy duty, and
The extreme operating conditions such as card tank, secondary device, thus accurate evaluation main shaft device load-carrying properties, liner non-skid property, damper brake braking
Performance, for ensuring that vertical shaft hoisting safety is of great significance.Vertical shaft hoist is broadly divided into headframe formula and two kinds of console mode.
