Vertical shaft hoist split type flat tail rope swing control device and method

Abstract

The invention discloses a split-type flat-tail rope swing control device for a shaft hoist, which includes a support motor, a support, a splint, a bolt, a support shaft support, a support shaft, a limit motor, an interference swing suppression bracket, a torsion spring, a longitudinal Gears, gear shafts, transverse gears, limit shafts, idler rollers with pads, retaining wheels, retaining wheel pads and counterweights, use a flat swing control device for 90° rotation, which can align the flat shaft radially along the wellbore during deployment. The tail rope is limited, and can be returned to the side of the tank beam when it is retracted. The split arrangement can solve the problem of cutting the space of the rigid tank to the side of the tank beam. The gear set right-angle transmission is used to make the limit shaft rotate 180°. The limit shaft is gradually clamped and limited from both sides of the flat tail rope, so that the swing of the hanging section of the flat tail rope can be safely and reliably controlled by multi-point guidance, and the swing of the flat tail rope is limited to a large extent from the root. The structure is novel, simple and practical , which can ensure the safe operation of the flat tail rope counterweight balance system of the shaft hoist.

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
