Technical Field

The invention relates to the technical field of coal mines, in particular to a skip bucket shaft well mouth sealing maintenance platform.

Background

Vertical hoisting of skip shafts is a common technological mode for pit mining mountains. With the development of the technology, the mining depth is continuously improved, and the running speed of the equipment is faster and faster to ensure the production efficiency. Because the ore lifting and conveying process is a key process in the whole production flow, the requirements on the maintenance of the skip in the main hopper door and the auxiliary hopper door are higher and higher, and the spot inspection per shift according to the safety management standard of mine equipment is indispensable. Close scrutiny and rapid replacement of parts are therefore essential conditions for ensuring safe production. However, because of the limited operating conditions of the skip, whether in the shaft or in the shaft tower, the skip must have a minimum safety distance of 300mm from the fixed platform or steel beam as a safety specification, and this distance is already above 500mm depending on the configuration of the skip. Such a distance is not intended to be a reliable support for close inspection, and is really unsafe for a deep pit several hundred meters below. At present, the inspection and maintenance of the skip which is close to the main and auxiliary hopper doors are generally realized by building a temporary platform by adopting a wood plate. The requirement for operators is high when the platform is built. Not only the technique but also the physical strength is required. The key is that the building is required to be immediately dismantled after use. Although the inspection and maintenance frequency is not high, each building and dismantling still needs 2-3 hours. Therefore, the working platform which can safely and quickly approach the skip is very beneficial to enterprises. At present, vertical shaft wellheads of a plurality of mines are not sealed, people or animals are basically prevented from entering the vertical shaft wellheads by adopting a fence, and other foreign matters cannot enter the vertical shaft wellheads in a protection capacity. At present, a plurality of cables and detection instruments are arranged in a shaft, and especially when a shaft bottom ore loading device needs to be overhauled and replaced, the shaft top is closed to ensure safety. Therefore, the wellhead sealing device capable of being opened and closed quickly is completely necessary for safe production of mine enterprises.
