Technical Field

Background

The main vertical shaft has the disadvantages that the junction between the shaft and the roadway is constructed at four places, the loading chamber is constructed at two places, the shifting frequency of the cross line is more, the traditional method of lowering two side lines is used for shifting the cross center line, and the wire rope is used for pulling the wire rope along the two side lines to be led to the well wall, so that the method is inconvenient to operate on site, and the shifting precision requirement and the use are not easy to achieve due to the swinging of the side lines.

When the main vertical shaft equipment is installed and constructed, in order to accurately install irrigation channel beams, pipelines and the like, a wire is required to be amplified to a lower shaft mouth of the shaft from a ground sealing disc by a wire car according to design requirements before construction, and the wire is fixed on a wire stabilizing beam at the lower shaft mouth to be used as a vertical datum line for installing the shaft equipment. In the traditional wire releasing process, 4 large wires need to be released, constructors stably release the large wires one by one, and then the large wires are fixed on a shaft wire stabilizing beam by using a wire stabilizing clamp. Because the shaft is influenced by wind flow and water spraying, the large line can swing back and forth endlessly in a certain range, and the deeper the shaft, the larger the swing is, the stillness cannot be realized.
