Technical Field

The invention relates to the technical field of mine hoisting equipment, in particular to a split type flat tail rope swing control device and method suitable for a vertical shaft elevator.

Background

The vertical shaft hoist as mine hoisting equipment consists of motor, main shaft unit, steel cable, hoisting container, tail rope and guide track, is used in hoisting ore, lowering material, raising and lowering personnel and equipment and is the connection junction between mine shaft and ground. The tail rope is installed in two promotion container bottoms through linkage as the counter weight of vertical elevator, its both ends, plays key counter weight balanced action at the endless promotion of vertical with transfer in-process.

The tail rope is divided into a round tail rope and a flat tail rope. The two flat tail ropes are generally arranged, and the suspension points of the two flat tail ropes can freely swing along the axis of the pin shaft of the suspension device. When a heavy-load lifting container runs at a high speed in a narrow and long shaft, the container body can easily swing transversely in the shaft, the flat tail rope is used as a balance weight arranged at the bottom of the lifting container and can swing transversely along with the lifting container, the two tail ropes are easy to rub and kink in the lifting and placing process of the container body, and therefore the flat tail rope is worn, broken and stranded or even broken, and the safety of a balance weight system is seriously threatened. The coal mine safety regulation stipulates that the tail rope must be checked 1 time per week, the broken wire is scrapped for more than 10 percent, or the tail rope must be replaced immediately when the number of broken wires is suddenly increased or the elongation is suddenly accelerated, and the scrapping standard is 4 years. In order to ensure the safety of the counterweight tail rope and prolong the service life of the counterweight tail rope, aiming at the swing control of the flat tail rope, at present, a single-layer or double-layer frame limiting device consisting of transverse and longitudinal rollers is mainly arranged at the bottom of a shaft to control the swing of the tail rope, such as tail rope isolation protection devices with patent authorization numbers of ZL201820982001.4 and ZL 200920306269.7. However, the following problems still exist in the existing research: firstly, installing a frame limiting device at the bottom of a shaft, avoiding kinking of a bent section of a flat tail rope by mainly utilizing a rope separating principle, and not limiting the swing of the flat tail rope from the root, particularly along with the continuous increase of mining depth, the large swing of the flat tail rope is caused by high-speed heavy-load lifting, so that the collision and friction problem exists among the hanging section of the flat tail rope occupying a large proportion, and the service life of the flat tail rope is reduced; secondly, the weaving form of the flattail rope also determines that the flattail rope is difficult to adopt a guide wheel for synchronous guiding and tensioning. Therefore, there is a need to research a flattail rope swing control device, which performs multi-point guiding control on the swing of a suspension section flattail rope occupying a large proportion, fundamentally limits the swing of the flattail rope to a large extent, is suitable for a narrow and long shaft, does not interfere with the normal operation of a counterweight system, and can allow the difference of the elongation deformation and the longitudinal movement of the flattail rope, so as to ensure the safe operation of a shaft lifting counterweight balance system, and the prior art lacks a corresponding control device.
