Description

Console mode vertical shaft hoisting joint debugging test device and method
Technical field
The present invention relates to a kind of joint debugging test devices and method suitable for vertical shaft hoist
Background technique
Vertical shaft hoist is equipped as main mine hoisting, is responsible for and is promoted coal spoil, lower putting material, lifts personnel It is the connection hinge on underground coal mine and ground with the vital task of equipment.Elevator joint debugging test refer to main shaft device (including volume Cylinder, main shaft, bearing block), liner, braking system etc. is mating install successfully after, can joint-detection main shaft device and braking system Normal and extreme operating condition is adapted to, is the committed step before elevator in-site installation.Meanwhile vertical shaft hoist is as disposable installation Large foundation equipment, especially headframe formula vertical shaft hoist, in-site installation needs biggish installation cost, thus before dispatching from the factory Joint debugging test be required to reflect the driving of mine hoist, braking ability comprehensively, avoid secondary installing from bringing great peace Fill debugging cost.
Currently, the joint debugging test of vertical shaft hoist is mainly idle running, i.e., it is empty merely with motor drive main shaft device Transhipment row does not carry out load test, thus anti-for main shaft device load-carrying properties crucial in mine shaft hoist system, liner Slip energy, brake performance can not accurate evaluations.Due to the geological conditions multiplicity of coal mine, to promotion load, speed is promoted Degree also produces different demands, thereby produces different drum diameters, reel encloses cornerite, wirerope radical, wirerope spacing Polytypic vertical shaft hoist causes to be difficult to use unified device to elevator performance test, and mentions for the vertical of different size The machine of liter builds assessment device respectively, will generate great construction and operation cost, is unsatisfactory for economy demand.Which results in enterprises It is difficult to build the vertical shaft hoist of various models on corresponding load and braking performance test platform before factory, lacks dedicated joint debugging Test device predominantly stays in theoretical calculation and three-dimensional machinery emulation.
Currently, the detection for mine hoisting system is studied, main concentrate detects active service mine, such as application No. is 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 Status monitoring is carried out to Active Service, and lacks the performance test to mine shaft hoist system in a pre-installation, and the latter can be to each 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. In structure, for console mode compared with headframe formula, lineoutofservice signal pull and main shaft device gravity direction are inconsistent.Herein for console mode Vertical shaft hoisting joint debugging test is studied.
