Embodiment 1

[0047] A non-excavation repairing device for small-diameter underground pipelines, comprising a first working mechanism located on one side of the internal collapse and deformation of the underground pipeline 1 to be repaired, and a second working mechanism located on the other side of the internal collapse and deformation of the underground pipeline 1 to be repaired. A working mechanism, a third working mechanism arranged between the first working mechanism and the second working mechanism, set on the first working mechanism and the second working mechanism for guiding and positioning the working process and monitoring the construction status The monitoring mechanism is respectively arranged on the right side of the first working mechanism and the cutting mechanism on the left side of the second working mechanism for circularly cutting the underground pipeline, and the first quick-drying cement nozzle 3 arranged on the cutting mechanism, The second quick-drying cement nozzle 4...

Embodiment 2

[0063] The difference from Embodiment 1 is that the third working mechanism includes three cylinders 20 with constricted openings arranged radially on the outer surface of the inner polygonal sleeve 19, and all the cylinders 20 are uniform in circumference. Distributed on the outer surface of the inner polygonal sleeve 19, a first automatic telescopic rod 21 is arranged in the axial direction in the cylinder body 20, and an insertion rod 22 is arranged at the end of the first automatic telescopic rod 21, and the insertion rod 22 The end portion protrudes from the constriction opening of the cylinder body 20 .

[0064] The third working mechanism also includes a second automatic telescopic rod 23 arranged radially on the outer surface of the inner polygonal sleeve 19, the end of the second automatic telescopic rod 23 is provided with a bearing plate 24, and the bearing plate 24, a drill bit 25, a third automatic telescopic rod 26 and a sixth automatic telescopic rod 27 are arra...

Embodiment 3

[0068] The difference between it and the second embodiment is that the cutting mechanism includes a low-speed motor 29 arranged on the side of the corresponding shaft seat, a driving gear 30 arranged on the output shaft of the low-speed motor 29, and a drive gear 30 arranged on the corresponding rotating shaft through a bearing sleeve and The driven gear 31 matched with the driving gear 30, the fourth automatic telescopic rod 32 arranged on the end face of the driven gear 31, and the end of the fourth automatic telescopic rod 32 are used to divide the parts to be repaired. The concrete cutting machine 33 of underground pipeline 1, described first quick-drying cement nozzle 3 is arranged on the shell bottom of described concrete cutting machine 33; The structure of the cutting mechanism on the described second working mechanism and described first working mechanism The structure of the cutting mechanism is the same, the difference is that: the low-speed motor on the first workin...

Abstract

The invention discloses small-diameter underground pipeline non-excavation type repair equipment. The small-diameter underground pipeline non-excavation type repair equipment comprises a first workingmechanism and a second working mechanism which are separately positioned at the two sides of a collapsed and deformed part inside a to-be-repaired underground pipeline, a third working mechanism positioned between the two working mechanisms, a monitoring mechanism arranged on the first working mechanism and/or the second working mechanism, cutting mechanisms which are separately arranged at the right side of the first working mechanism and the left side of the second working mechanism, a first quick-drying cement spray nozzle arranged on the cutting mechanisms, a second quick-drying cement spray nozzle arranged on the third working mechanism, water retaining mechanisms which are separately arranged at the left side of the first working mechanism and the right side of the second working mechanism, and a control mechanism. One section, which is collapsed and deformed, of an underground pipeline only needs to separate and cut out, the collapsed and deformed part is rotated to the side surface or the bottom, and the first quick-drying cement spray nozzle and the second quick-drying cement spray nozzle are finally utilized to perform cement filling repair on a cutting seam, a jack andthe collapsed and deformed part, so that a novel pipeline is not required.

Description

technical field [0001] The invention relates to the technical field of repairing municipal underground pipelines, in particular to non-excavation repairing equipment for small-diameter underground pipelines. Background technique [0002] Urban underground pipelines are one of the important infrastructures that support social development and ensure people's lives. Pipeline maintenance is a necessary means to ensure its normal mechanism and functions. Pipeline repair work is mainly carried out through two repair methods: excavation repair and trenchless repair. Among them, the excavation repair is to directly dig the pipeline, and then repair the pipeline to be repaired. The environmental problems and economic impact of the excavation and repair of the pipeline are relatively large, and it is easy to cause safety accidents such as damage to the remaining pipelines. Non-excavation restoration has gradually attracted more attention as a low-impact and low-maintenance restoratio...
