Hydraulic drive type steel wire rope guide flat tail rope swing controlling device and method

Abstract

The invention discloses a hydraulic drive type steel wire rope guide flat tail rope swing controlling device and method which are suitable for steel wire rope guides. A flat interference swing restraining device is adopted to rotate at 90 degrees, the flat interference swing restraining device can limit a tail rope in the radial direction when being extended, and the flat interference swing restraining device can retract to the side face of a guide beam when being withdrawn. Hydraulic drive is adopted to enable limiting shafts to horizontally rotate and gradually clamp and limit the tail ropefrom the two sides of the rope tail. Limiting hydraulic cylinders are provided with tension springs, the top ends of the limiting shafts are provided with counter weights, under the power failure emergency working condition, the limiting shafts are made to recover to the release state under the action of pull force of the tension springs, a supporting shaft rotates to the side face of the guide beam under the gravity action of the counterweights, interference in operation of a hoisting container is avoided, then multi-point guide and control of swing of the overhung section flat tail rope areconducted, and swing of the tail rope is fundamentally limited to a great extent. The hydraulic drive type steel wire rope guide flat tail rope swing controlling device is novel in structure, reliablein performance and guarantees safe operation of a vertical shaft lifting flat tail rope counterweight balance system.

Description

technical field [0001] The invention relates to a mine hoisting equipment technology, in particular to a hydraulically driven steel wire rope tank road flat tail rope swing control device and method suitable for a vertical shaft hoist. Background technique [0002] As a mine hoisting equipment, the vertical shaft hoist is mainly composed of a motor, a main shaft device, a wire rope, a hoisting container, a tail rope and a guide rail. It is responsible for the important tasks of lifting ore, lowering materials, and lifting personnel and equipment. It is the connection hub between the mine underground and the ground. . The tail rope is used as the counterweight of the shaft hoist, and its two ends are installed on the bottom of the two hoisting containers through the suspension device, which plays a key role in balancing the counterweight during the hoisting and lowering of the shaft circulation. [0003] There are two types of tail ropes: round tail rope and flat tail rope. ...

AI Technical Summary

Problems solved by technology

However, the above research still has the following problems: First, the installation of the frame limiter at the bottom of the wellbore mainly uses the principle of splitting the rope to avoid the kink of the flat tail rope in the curved section, and does not limit the swing of the flat tail rope from the root, especially with the mining As the depth continues to increase, the high-speed and heavy-duty lifting causes the flat-tail rope to swing greatly, causing friction problems between the flat-tail ropes that account for the vast majority of the suspension section, resulting in a reduction in the life of the flat-tail rope; second, the weaving of the flat-tail rope The form also determines that it is difficult to use guide wheels for synchronous guiding and tensioning

Therefore, it is necessary to study a flat-tail rope swing control device, which can control the swing of the flat-tail rope in the overhanging section by multi-point guidance, and limit the swing of the flat-tail rope to a large extent from the root, which is suitable for narrow and long shafts and does not require Interfere with the normal operation of the counterweight system, and can tolerate the difference in the elongation and deformation of the flat tail rope and the longitudinal movement, so as to ensure the safe operation of the shaft lifting counterweight balance system, but there is currently a lack of corresponding control devices
