Description
Technical Field
The utility model relates to a mine lifting machine technical field specifically is a mine lifting machine wire rope slack rope protection system.
Background
In the vertical shaft lifting, rope loosening caused by rope breakage, tank clamping, over-discharge and the like can occur; in the inclined shaft lifting, when a hook is taken off, when an upper lifting load enters a variable slope point, and after a lower releasing load enters the variable slope point, when a steel wire rope bounces due to speed change, a lifting container falls off a channel in a tunnel or is blocked, broken, over-released and the like to cause rope loosening.
The fourth hundred twenty-three rules for coal mine safety of the seventh clause of the first clause stipulates that the lifting device must be provided with safety protection as follows: (seventhly) rope loosening protection: the winding type hoisting machine should be provided with a rope loosening protection device and connected into a safety loop or an alarm loop. When the skip bucket is lifted, the slack rope protection device is not allowed to release coal in the coal bunker after the slack rope protection device acts. The execution description is as follows: the rope loosening protection refers to a protection measure when a steel wire rope of the winding type lifting system is loosened. When a rope is loosened in a shaft, a rope loosening protection signal is connected to a pre-alarm loop and a safety loop of a hoist electric control system; when the rope is loosened in the parking lot at the upper part of the inclined shaft, the rope loosening protection signal is connected to an alarm loop of the electric control system of the hoist.
So far, the rope loosening protection of most of the hoisting machines is realized by using a travel switch, namely, the travel switch is fixed on a wall body at a rope outlet of a steel wire rope of a hoisting machine room by using a fixing support, and the travel switch is positioned below the steel wire rope and can be pressed when the steel wire rope sags. And the steel wire rope is spaced from the travel switch according to the operation experience. When the steel wire rope is loosened, the travel switch is pressed, and the normally closed contact of the travel switch breaks a safety loop, so that the elevator performs safety braking.
The above-mentioned devices have the following disadvantages: 1) the distance between the steel wire rope and the travel switch is not well adjusted, and frequent parking can be caused if the distance is too small; when the distance is too large, it is difficult to operate the stroke switch even if the rope is loosened, and thus the protection effect is not achieved. When the hoister stops in the material lifting process, the rope shaking phenomenon can occur, and false operation can occur when the hoister touches a travel switch; 2) the travel switch is of a mechanical structure, is easy to cause mechanical abrasion and has short service life; 3) the response is not sensitive.
therefore, in view of the above current situation, there is an urgent need to develop a rope loosening protection system for a steel wire rope of a mine hoist, so as to overcome the shortcomings in the current practical application.
