Background technology
At present, in mine hoisting field, the depth detection of hoisting container substantially measures reel by rotary encoder
The angle of rotation, is converted into the move distance of steel wire rope further according to drum diameter, obtains indirectly the depth information of hoisting container.By
There is certain elasticity, hoisting container by reasons such as external impacts in long steel wire rope itself, the mode of this indirect detection is obtained
Depth information it is very unreliable, such as cause hoisting container card tank in running when the reason such as deforming due to cage guide, carry
Time of day and depth that driver does not know about hoisting container is risen, reel works on and is just likely to the major accident for causing disconnected rope.
When hoisting container needs to stop in stage casing, need first to slow down and creep, by mechanical type or electromagnetic type travel switch
Stop sign is sent, at this moment because the reason such as steel wire rope elasticity, actual anchor point is not very accurate, and the person of giving people is upper and lower, material
Transport brings some difficult and potential safety hazards.And subsurface environment is severe, has damage during travel switch, bring not to normal operation
Just, there is also potential safety hazard.
But in ultra-deep mine (more than 1500 meters), the elastic elongation of steel wire rope affects to ignore, hoisting container
Load is bigger, the speed of service faster, by rotary encoder indirect detection+travel switch send the method error of stop sign compared with
Greatly, the problems such as may bringing inaccurate stop, shakiness, the person of giving people, vehicle bring difficulty and potential safety hazard up and down.
