Urban underground pipeline rotary spraying repairing device

Abstract

The invention relates to the technical field of underground pipeline repairing equipment, in particular to an urban underground pipeline rotary spraying repairing device. Due to the long-time rolling or other reasons of vehicles, cracks or damage of the underground pipeline can occur, at present, the main maintenance method is that a roadbed is excavated and the pipeline is replaced, but the mode that the roadbed is excavated and the pipeline is replaced needs traffic control, the engineering quantity is large as well, so that the manpower and material resources consummation is huge, a discharging head is driven by a pneumatic motor to rotate at a high speed, the repairing coating conveyed by a feeding pipe is sprayed on the inner wall of the pipeline under the action of the centrifugal force of the discharging head, a supporting foot assembly can be used for fixing and supporting the pneumatic motor, so that the central axis of the discharging head on the pneumatic motor and the axis of the pipeline coincide, then the coating is more uniform in spraying, the supporting foot assembly can drive the discharging head to slide in the pipeline under dragging of a rope, the axial spraying of the inner wall of the pipeline is completed, the pipeline repairing efficiency is effectively improved, and the maintenance cost is reduced. The device is mainly used for rotary spraying repair of the urban underground pipeline.

Description

technical field [0001] The invention relates to the technical field of underground pipeline repairing equipment, in particular to a rotary spray repairing equipment for urban underground pipelines. Background technique [0002] Urban underground pipelines refer to the water supply, drainage and other pipelines buried underground within the city, which are the important infrastructure and lifeline to ensure the operation of the city. In some road sections, due to the long-term rolling of vehicles or other reasons, the pipelines buried in the ground may be cracked or damaged, resulting in water leakage and loss of pipeline transportation function. At present, the main maintenance method is to excavate the roadbed to replace the pipeline. However, the excavation of the roadbed to replace the pipeline requires traffic control, and the amount of work required to excavate the roadbed is large, resulting in traffic obstruction and huge human and material resources. SUMMARY OF THE...
