Embodiment 1

[0044] A non-excavation repairing device for a drainage pipeline, comprising a first working mechanism located on one side of the internal collapse and deformation of the drainage pipeline 1 to be repaired, and a second working mechanism located on the other side of the internal collapse and deformation of the drainage pipeline 1 to be repaired 2 , a third working mechanism arranged between the first working mechanism and the second working mechanism, which is arranged on the first working mechanism and the second working mechanism for guiding and positioning the operation process and monitoring the construction status Mechanisms, which are respectively arranged on the right side of the first working mechanism and the left side of the second working mechanism are used to circularly cut the drainage pipe. The first quick-drying cement nozzle 3 arranged on the cutting mechanism is arranged on the The second quick-drying cement nozzle 4 on the third working mechanism, and the cont...

Embodiment 2

[0058] 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 .

[0059]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 arran...

Embodiment 3

[0063] 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 drainage 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 is the same, the difference is that: the low-speed motor on the first working mechanism is set on the right side of the first shaft seat, and its driven gear is sleeved on the first rotating shaft t...

Abstract

The invention discloses a drainage pipeline non-excavation repairing device. The drainage pipeline non-excavation repairing device comprises a first working mechanism which is located on one side of the collapsing deformation position of the interior of a to-be-repaired drainage pipeline, a second working mechanism located on the other side of the collapsing deformation position of the interior ofthe to-be-repaired drainage pipeline, a third working mechanism arranged between the first working mechanism and the second working mechanism, monitoring mechanisms arranged on the first working mechanism and / or the second working mechanism, cutting mechanisms which are arranged on the right side of the first working mechanism and the left side of the second working mechanism correspondingly, first quick-setting cement nozzles arranged on the cutting mechanisms, a second quick-setting cement nozzle arranged on the third working mechanism, and a control mechanism which is located on the groundand used for controlling the whole repairing device to concertedly work. According to the drainage pipeline non-excavation repairing device, only the collapsing deformation position of the drainage pipeline needs to be separated and cut out at first and then is rotated to the side or the bottom, finally, a cut seam, an inserting hole and the collapsing deformation position are subjected to cementfilling repairing through the first quick-setting cement nozzles and the second quick-setting cement nozzles, and repairing is achieved without a new pipeline.

Description

technical field [0001] The invention relates to the technical field of repairing municipal drainage pipes, in particular to a non-excavation repairing device for drainage pipes. Background technique [0002] Urban drainage pipes 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 restoration method for infrastructure. [0003...
