Description

Electrodeless rope type 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 The deep-well hoisting device state monitoring method of CN201710531454.5, which is based on signal fused, to be shelled from hybrid monitoring signal Fault-signal is separated out, system running state is monitored.Meanwhile some scholars are by building various test bed testing lifting systems Can, as authorization power number uses motor forceps horizontal pulling for the ultra-deep mine hoisting system testing stand of ZL 201410528414.1 Mode substitutes the operating condition of the vertical-lift under actual condition, simulates a variety of mine hoisting functions；Grant number is ZL 201610118998.4 ultra-deep mine hoisting system Multi-functional analog test platform can simulate ultra-deep mine under actual condition Hoisting device motion state obtains hoisting device Specifeca tion speeification under fault condition；Grant number is ZL 201410728399.5 Km deep-well winding hoisting churn friction system can simulate different rotating speeds, acceleration, impact velocity, specific contact pressure Under churn friction duty.The studies above is primarily present following problems: first, state prison mainly is carried out to Active Service It surveys, and lacks the performance test to mine shaft hoist system in a pre-installation, and the different model that the latter can produce each manufacturer is vertical Well lifting system is unified before installing at the scene to check, and the retest of large-scale manufacturing enterprise is avoided to put into, and promotes small-sized production enterprise The manufacturing quality of industry ensures lifting system safety from source；Second, it is examined mainly for the lifting system of single model It surveys, can not effectively adapt to different drum diameters, reel encloses cornerite, the lifting system of wirerope radical, wirerope spacing；The Three, lack load detection in a pre-installation, it can not to main shaft device load-carrying properties, liner non-skid property, brake performance Accurate evaluation；4th, in-service mine is detected, feature of the main shaft device under non-loaded and heavily loaded can not be efficiently used Parameters variation, and this be diagnose main shaft device abnormal deformation, crackle the defects of important feature, while can not analog card tank, The pernicious operating condition such as twice loading, and can the latter be to judge main shaft device, friction lining, braking system bear the weight of extreme operating condition It refers to.Thus, it is necessary to a kind of vertical shaft hoisting joint debugging test device is studied, it can be to the main shaft of the lifting system of different model Device, liner and braking system carry out joint debugging test, the poles such as the nominal situations such as simulation no-load, heavy duty and card tank, secondary device Operating condition is held, thus accurate evaluation main shaft device load-carrying properties, liner non-skid property, brake performance, for ensuring vertical Safety is promoted to be of great significance.
