Background
The friction type multi-rope hoister mainly comprises a motor, a speed reducer, a friction wheel, a braking system, a depth indicator, a speed measuring and limiting system and a control system, and is driven by an alternating current or direct current motor.
When the low-speed motor is adopted, a speed reducer is not needed, the motor is directly connected with the winding drum main shaft, or a motor rotor is arranged at the tail end of the winding drum main shaft. In case of emergency, the braking system should produce two-stage safety braking via the hydraulic system capable of regulating braking torque to ensure timely stopping of the hoister and avoid over-braking. The braking system of an AC motor driven elevator also has sensitive braking torque adjustability to accurately control the speed of the elevator near the stopping point.
At present, the multi-rope friction type hoister is widely applied in a coal mine environment, steel wire ropes on the multi-rope friction type hoister are seriously abraded along with the prolonging of the service life of the multi-rope friction type hoister, and according to the standard of replacing the steel wire ropes in the coal mine, all old steel wire ropes need to be uniformly replaced with new steel wire ropes with the same specification when the steel wire ropes are replaced, so that the potential safety hazard caused by unbalanced stress of the steel wire ropes due to different steel wire rope types is avoided.
The traditional rope replacing method is that a slow speed stable vehicle is arranged at a well mouth, a stable vehicle is wound with a new rope, the new rope is in butt joint with an old rope at the well mouth, an old rope head in a well is disassembled, the stable vehicle is used for lowering, and the old rope is recovered in a tunnel in the well.
According to the traditional method, large equipment such as a slow-speed car stabilizer needs to be arranged at a well mouth, cage (hopper) in the upper part and the lower part of a well are provided with rope separation frames, and constructors need to operate underground, so that the labor intensity is high, the safety risk is high, meanwhile, the construction cost is increased, and the efficiency is reduced.
The new and old rope mutual-taking method is also a construction method commonly used for replacing a hoisting steel wire rope by a multi-rope friction type hoisting machine, and the new rope of the old rope belt is firstly used for lowering, and then the old rope of the new rope belt is used for recovering. However, single replacement, half-and-half replacement and four simultaneous replacements are mostly adopted, and the used rope replacing equipment is expensive in manufacturing cost.
Aiming at the defects of the traditional rope changing method, in the prior art, a plurality of optimized and improved technologies for changing and changing the rope of the steel wire rope exist, for example, in the patent application number of CN201911179845.0, the patent name of the system and the method for quickly changing the rope of the vertical shaft friction type hoisting machine, the system and the method mainly comprise the following steps: s1: threading a small winch steel wire rope; fixing a small steel wire rope with the hook head phi of 8mm on an old steel wire rope by using a reverse climbing buckle, starting a large winch, stopping and locking the winch when the rope head reaches a hoisting sheave of a south skip bucket, and putting a small winch rope on a rope supporting wheel by a constructor at a hoisting sheave platform; continuously starting the large winch, and taking the rope of the small winch to the top wheel of the north skip; the large winch is continuously started, the steel wire rope of the small winch is brought to the position of the skip bucket on the north side, and the small winch rope is separated from the old rope; then fixing the rope end, and starting a small winch to ensure that the steel wire rope has enough tension; a person stands on the skip to bind a small winch rope and fixes the small winch rope to the east so as not to influence the operation of the large winch; s2: wrapping a new rope; s3: old rope and new rope: the old rope is tied with a new rope to form a combined plate; s4: locking, replacing and making a hook head; s5: the new rope is provided with the old rope, and the old rope is detached and wound by a rope winding vehicle \8230 \ 8230; S6: performing test operation; and after confirming that the operation is not problematic, the winch is operated in a test mode.
It can be seen from the rope changing method described in the above patent technology that large complex structures such as a large winch and a small winch are externally installed when the rope is changed, and the problem that the new wire rope rubs the upper and lower head sheaves, the wire rope is wound and the rope is twisted easily occurs in the wire rope layout which is staggered like a telephone in the rope changing process.
