Embodiment Construction
[0067] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings. Among them, the directional nouns such as "upper", "lower", "front" and "back" mentioned in this article are based on figure 1 orientation as a reference. The side where the frame 12 is connected to the slag suction pipe assembly 20 is used as the front end.
[0068]On the one hand, a vertical pipeline connection device proposed by the embodiment of the present invention can be used in the slag discharge system of the vertical shaft. Among them, the slag discharge system adopts the form of fully flooded ground slag discharge. That is to say, the slurry pump of the slag discharge system is arranged on the ground of the wellhead, and the slurry pump sucks the sludge in the vertical shaft through the vertical pipeline connection device provided by the present inve...

The invention relates to a vertical pipeline connection device and a method thereof, in particular, a vertical pipeline connection device. It includes a support assembly and a pipe fitting set fixed at the wellhead of the shaft, and the pipe fitting set is located at the wellhead of the shaft and is installed vertically downward on the support assembly. The pipe fitting set includes telescopic pipe fittings fixedly connected to the support assembly and extension pipes detachably connected to the lower end of the telescopic pipe fittings. When the vertical pipeline connection device is working, the telescopic pipe is extended to move the extended pipe downward in turn, and the lower end of the extended pipe is detachably connected to the joint pipe of the downhole equipment. The pipe diameters of telescopic pipe fittings, extension pipe fittings and joint pipe fittings are all greater than 500mm. The device occupies a small space, and the extended pipe fitting on the clamping trolley runs on the track to connect with the telescopic pipe fitting conveniently. The connection efficiency is high. The pipeline channel with a diameter of more than 500mm greatly improves the slag discharge capacity of the slag discharge system.
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...
