Vertical pipeline splicing device and method

Abstract

The invention relates to a vertical pipeline splicing device and method. The vertical pipeline splicing device comprises a supporting assembly and a pipe fitting group, wherein the supporting assemblyis fixed at a shaft mouth; the pipe fitting group is positioned at the shaft mouth, is mounted on the supporting assembly in a vertical-downward manner, and comprises a telescopic pipe fitting and anextension pipe fitting; the telescopic pipe fitting is fixedly connected onto the supporting assembly; and the extension pipe fitting is detachably connected with the lower end of the telescopic pipefitting. During the work of the vertical pipeline splicing device, the telescopic pipe fitting extends; accordingly, the extension pipe fitting gradually moves down and the lower end of the extensionpipe fitting is detachably connected with a joint pipe fitting of downhole equipment; and the pipe diameters of the telescopic pipe fitting, the extension pipe fitting and the joint pipe fitting areall greater than 500 mm. The vertical pipeline splicing device has the beneficial effects that the occupied space is small; the extension pipe fitting on a clamping trolley runs on a track, the way tosplice the extension pipe fitting with the telescopic pipe fitting is convenient and fast, and the continuous splicing efficiency is high; the upper and lower ends of the extension pipe fitting are quickly connected with the telescopic pipe fitting and the joint pipe fitting through flanges correspondingly, so as to form a pipeline channel with the pipe diameter of 500 mm or above; and accordingly, the deslagging capacity of a deslagging system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of shaft shield machines, in particular to a vertical pipeline connection device and a method thereof. Background technique [0002] With the increasing market demand for large-diameter shaft shield machines, most of the existing shaft slag discharge systems use underground semi-flooded slag discharge, because the slurry pump of the slag discharge system needs to be used along with the shield machine, etc. The equipment goes downhole together, and the supporting equipment of the slag discharge system is relatively large and complex, so the size of the slurry pump is limited, so the diameter of the slag suction nozzle of the slurry pump is limited, resulting in only a small diameter The pipeline is connected to slag discharge, therefore, the slag discharge capacity is greatly limited. [0003] The above problems urgently need to be solved. Contents of the invention [0004] (1) Technical problems to be so...
