Split type flat tail rope swing control devices for vertical shaft hoister and method thereof

Abstract

The invention discloses split type flat tail rope swing control devices for a vertical shaft hoister. The split type flat tail rope swing control devices comprise support motors, support bases, clamping plates, bolts, support shaft support bases, support shafts, limiting motors, interference suppression swing holders, torsion springs, longitudinal gears, gear shafts, transverse gears, limiting shafts, carrier rollers with pads, blocking wheels, blocking wheel pads and counterweights; the flattened swing control devices are adopted for carrying out 90-degree rotation, so that the flat tail ropes can be limited in the radial direction of a shaft during unfolded, and the flattened swing control devices can be ascribed to the side surface of a shaft guide beam during retraction, by adopting the split type arrangement, the cutting problem of a rigid shaft guide to the side space of the shaft guide beam can be solved, the gear set right-angle transmission is adopted to make the limiting shafts rotate 180 degrees, so that the limiting shafts are enabled to gradually clamp and limit from the two sides of the flat tail ropes, the swing of the flat tail ropes of the overhanging section is subjected to safe and reliable multi-point guide control, the swing of the flat tail ropes is limited to a large degree from the root cause. According to the split type flat tail rope swing control device for the vertical shaft hoister, the structure is novel, simple and practical, and the safe operation of the flat tail rope counterweight balance system of the vertical shaft hoister can be guaranteed.

Description

technical field [0001] 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 shaft hoists. 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. The flat tail rope is generally set...

Problems solved by technology

However, the existing 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 bending section, and does not fundamentally limit the swing of the flat tail rope, especially with the As the mining depth continues to increase, high-speed and heavy-load lifting leads to large swings of the flat-tail ropes, causing rubbing problems between the flat-tail ropes that account for a large proportion of the suspension section, resulting in a reduction in the life of the flat-tail ropes; secondly, the flat-tail ropes The weaving 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
