Background technology
The overall process of mining production be unable to do without Mine haul and lifting work, and therefore, the quality of transport and lifting work is straight
Connect to be related to and produce in ore deposit and normally and efficiently can carry out.Mine hoist equipment is the throat of mining production, be collect mechanical, electrical, liquid in
The large-scale complicated system of one.It is a lifeline of mining production, is mainly used in carrying fortune ore, coal, material, Ren Yuanhe
Equipment, is hinge that mine down-hole production system is connected with ground surface plant.As pit mining moves towards deep and modern times
Change the requirement of the safe and efficient production of large-scale mine, the application of multi-lay winding formula elevator is maximized increasingly, with the growth of reel,
Weight and rotary inertia increase, and need bigger motor, and need bigger arrangement space, permissible using multi-lay winding reel
Cost-effective.Dual slope grooving is a kind of grooving form for being suitable for multi-lay winding, and it can be efficiently against conventional spool in multilayer
Shortcoming in terms of winding, avoids disorder cable, effectively extends the service life of steel wire rope.And, hoisting depth big with its hoisting power
Greatly, safety coefficient is high, and the remarkable advantage such as low cost is increasingly used in the mine hoisting of deep-well and ultra-deep mine.
With the increase of pit mining depth, in order to improve the conevying efficiency of deep-well and ultra-deep mine hoist, hoisting device inevitable to
Big lifting load and high lifting speed development, this also proposes requirements at the higher level, invar for the safety and reliability of lifting means
Cord can be deformed upon in working long hours, particularly operating mode suddenly change when pulling force and tension force suffered by steel wire rope easily make steel wire
There is fracture so as to cause basket of work falling accident in rope, cause casualties.
In the lifting process of friction drive hoist, common due to variable boom hoist cable overhang length and inertial load
Effect, boom hoist cable upper carry acceleration, at the uniform velocity, in the lifting process of deceleration a cycle, lift system can be vibrated, steel
Cord is also subjected to dynamic tension change, and the acceleration particularly in lifting, decelerating phase, the dynamic tension vibration of steel wire rope are larger, vibration
Frequency increases with the reduction of rope capacity.Vibration makes pulling force suffered by steel wire rope and tension change, and steel wire rope is produced radially
Deformation, affects rope service-life after long time period work, causes the serious accident of elevator.Because each layer of steel wire rope is received
To power be different and various, can effectively prevent mine accident if the deformation that can detect each layer of steel wire rope and tension force
Generation.So, dynamic monitor and the method for a kind of deep-well boom hoist cable radial deformation and tension force is proposed, probes into reel
The dynamic change of the real-time radial deformation of upper every layer of steel wire rope, reel outer wall zones of different pressure and steel wire rope tension be to
Close important.
Existing steel wire rope of hoist detection means includes：The utility model patent of Patent No. ZL201220715786.1 is public
A kind of multirope friction winder steel wire rope tension on-line monitoring device has been opened, can be by wireless transmitter module and pressure sensor
Collection steel wire rope tension is simultaneously wirelessly sent to wireless receiving module, not by Structure of hoist and the shadow of running status
Ring, the real-time monitoring to steel wire rope of hoist dynamic tension is realized, but the radial deformation of each layer of steel wire rope can not be detected；
The utility model patent of Patent No. ZL201420703971.8 discloses a kind of mine hoist tension monitoring system, it is achieved that
Mine steel wire rope tension remote real time monitoring, improves the security of mine hoist, however, the system detectio steel wire rope deformation makes
Three-point bending method accuracy is not high, it is impossible to accurately calculate the tension force suffered by steel wire rope；Application No.
The patent application of 201510634389.X discloses steel wire rope tension measuring method in a kind of lift system, is a kind of measurement indirectly
Method, does not carry out directly contact to steel wire rope, does not destroy steel cord structure, and the method can not measure the tension force of every layer of steel wire rope
Value.
