AI Technical Summary
In shaft construction, traditional methods of laying pipelines can easily lead to pipeline entanglement, occupy shaft space, and increase safety hazards.
The system employs a combination structure of wellhead support, winch assembly, towing wheel assembly, chain, and tube sheet. The chain and tube sheet are moved on a semi-circular frame by the roller, which enables the orderly deployment and retraction of the pipeline and avoids tangling.
This enabled the orderly placement and removal of pipelines within the shaft, reduced safety hazards, and optimized the utilization of shaft space.

Abstract
Claims
1. A pipeline deployment and take-up device for vertical shaft excavation, comprising: A wellhead support, comprising a rectangular frame located below and a semi-circular frame connected above the rectangular frame, the rectangular frame being positioned close to the wellhead of the vertical shaft, and the two ends of the semi-circular frame being suspended. A hoisting assembly, comprising a drum and a drive unit, wherein the drum is rotatably disposed at the middle position of the arc surface of the semi-circular frame, and the drive unit is used to drive the drum to rotate; A tow wheel assembly is disposed on the arc surface of the semi-circular frame, and the tow wheel assembly includes a plurality of rotatable tow wheels symmetrically distributed on both sides of the winch assembly; Its features are: The vertical shaft excavation pipeline deployment and retraction device also includes a chain wound around the arc surface of the semi-circular frame and a tube plate connected to the chain. The tube plate is provided with a fixing structure for fixing each pipeline. The hoisting assembly also includes a chain disc sleeved on the drum and matched with the chain. The outer circumference of the tug wheel is provided with an annular guide groove. The chain is engaged with the chain disc and placed in the guide groove. When the drum rotates, it can drive the chain and the tube plate to move from one side of the rectangular frame to the other side along the arc surface of the semi-circular frame, so as to realize the orderly deployment and retraction of each pipeline in the vertical shaft.
2. A pipe launch and retrieval device for use in shaft sinking according to claim 1, characterised in that: There are multiple tube sheets, which are equidistantly spaced on the chain, and the length of the pipeline between adjacent tube sheets is greater than the distance between adjacent tube sheets.
3. The pipe launch and retrieval device for use in shaft sinking according to claim 1, characterized in that: The chain has two sets and is spaced apart along the axial direction of the roller. The tube plate is transversely overlapped between the two sets of chains. The chain disc and the drag wheel assembly each have two sets and are respectively arranged corresponding to the two sets of chains.
4. A pipe launch and retrieval device for use in shaft sinking according to claim 3, characterised in that: The chain is positioned near the end face of the roller.
5. The pipe launch and retrieval device for use in shaft sinking according to claim 1, characterized in that: The suspended length of the semi-circular frame on the side closest to the shaft opening is greater than the suspended length on the other side.
6. The pipe launch and retrieval device for use in shaft sinking according to claim 1, characterized in that: The semi-circular frame is composed of an upper frame and a middle frame stacked together. The upper frame and the middle frame are locked together by bolts. The middle frame and the rectangular frame are locked together by bolts. The rectangular frame is fixed to the ground by bolts.
7. A pipe launch and retrieval device for use in shaft sinking according to claim 6, characterised in that: The height of the upper frame is equal to the height of the middle frame, and both are half the radius of the semi-circular frame.
8. The pipe launch and retrieval device for use in shaft sinking according to claim 1, characterized in that: The drive unit includes a drive motor connected to one side of the semi-circular frame and a reducer disposed inside the roller. The output shaft of the drive motor is connected to the input shaft of the reducer via a spline.
9. A pipe launch and retrieval device for use in shaft sinking according to claim 8, characterised in that: The reducer is provided with a grease injection port at its end. The grease injection port is connected to the interior of the reducer through a grease injection channel. A sealing plug is threaded onto the grease injection port.
10. A pipe launch and retrieval device for use in shaft sinking according to claim 8, characterised in that: The reducer is equipped with a preload spring and multiple combined seals to ensure axial preload and prevent grease leakage.
