TECHNICAL FIELD

[0001] The utility model relates to the technical field of underground pipeline construction, and particularly relates to a sliding guide device for lowering a pipeline. BACKGROUND

[0002] A well shaft drainage facility is an important component of a mine main drainage system, and the safety of a well shaft drainage pipeline will affect the safety of the entire mine. During mine production, because the underground water quality contains a large amount of minerals, scale is easily formed inside the pipeline, which leads to a decrease in the use efficiency of the well shaft pipeline, and replacement construction is required. How to replace the pipeline in a narrow well shaft and ensure the safety of construction personnel and equipment is a problem that must be considered first by construction personnel.

[0003] A conventional construction method is to cut the pipeline and then transport it using a cage. Because the well shaft that is being constructed has been used for more than 20 years, the space in the well shaft is narrow, and various pipelines, cables, and components are distributed throughout the well shaft, so it is not possible to transport all of them using a cage. It is necessary to transport them using the original pipeline installation space.

[0004] After multiple site surveys and scheme discussions, the construction personnel decided to use a well mouth stabilizer to hoist the pipeline and install guide rails and a matching guide device in the well shaft to limit the movement trajectory of the hoisted pipeline in the well shaft, so as to avoid shaking during the process of disassembling and transporting the pipeline and causing damage to other facilities in the well shaft. In order to solve the above problems, a sliding guide device for lowering a pipeline is provided. SUMMARY

[0007] A shell is provided with a sliding groove that penetrates through both ends, an open slot is arranged in the middle of the upper end of the shell, a bottom groove is arranged in the middle of the lower end of the sliding groove, a bottom roller is arranged in the bottom groove, and the bottom roller is in rotating connection with the shell. A plurality of top rollers are symmetrically arranged on the shell on both sides of the open slot, the top rollers are in rotating connection with the shell, and the top rollers penetrate in and out of the sliding groove.

[0008] Further, the binding part comprises:

[0009] A connecting ring is symmetrically welded on both sides of the bottom of the shell.

[0010] The tensioning rope is used for binding the pipeline and is fixed by the hooks and the connecting rings on both sides.

[0011] Further, the bottom roller and the top roller are bearings, the inner ring of the bearings is sleeved with a mandrel, and the mandrel is threadedly connected with the shell at both ends.

[0012] Further, the outer ring of the bearing is sleeved with a nylon layer.

[0013] Further, the shell is welded by angle steel and round steel, and the guide rail is an I-beam.

[0014] The utility model has the following beneficial effects: in the use process, through the rolling connection of the guide support and the guide rail, the pipeline to be transported is fixed on the guide support through the binding part, so that the pipeline does not shake during the lowering or lifting process of the stable vehicle, and the pipeline is transported through the preset track, so as to ensure the safety of pipeline construction.
