Connecting and fixing device for repairing water supply and drainage pipe and operation method of connecting and fixing device

Abstract

The connecting and fixing device comprises a mounting frame and a containing cylinder, the containing cylinder is transversely fixed to one side of the mounting frame, a guide cylinder is arranged at the end, away from the mounting frame, of the containing cylinder, and a wheel shaft is rotationally arranged below the mounting frame; wheels are fixed to the outer sides of the wheel shafts, a rotating seat is fixed to the front face of the containing cylinder, a belt wheel is rotationally arranged in front of the rotating seat, a driving belt is in transmission connection between the belt wheel and the wheel shafts, a transmission gear ring is coaxially fixed to the rear side of the belt wheel, and the guide cylinder is matched with the containing cylinder in a rotating mode. The spraying repair equipment has the beneficial effects that the winch is used for pulling the spraying repair equipment to move, meanwhile, traction power of the winch is used as spraying power of a cement mortar coating, the spraying speed of the cement mortar coating can be adjusted according to the repairing states of the water supply and drainage pipelines in different areas, and then the water supply and drainage pipelines can be repaired according to the actual situation; the practicability is high.

Description

technical field [0001] The invention relates to the field of equipment for repairing water supply and drainage pipes, in particular to a connection and fixing device for repairing water supply and drainage pipes and an operation method thereof. Background technique [0002] Municipal underground water supply and drainage facilities are the basic guarantee for urban economic development and daily life. According to the statistics of the Ministry of Construction, nearly half of the domestic drainage pipes were laid before 2000, accounting for 44.97%. The proportion of drainage pipes before the 1980s also reached 6.93 %, due to the difficult access and invisible characteristics of the pipeline system below the surface, it is difficult to detect, maintain and repair the pipeline system. When the pipeline is damaged, it needs to be repaired to maintain the normal use of the water supply and drainage function. The spraying method is often used as The repair process of the water su...

AI Technical Summary

Problems solved by technology

[0003] The applicant found that there are at least the following technical problems in the prior art: the existing water supply and drainage pipeline spraying repair equipment needs to be connected to electricity, and due to the complex terrain of the underground water supply and drainage pipeline network, long-distance cables are required to connect to the mains, and the wiring operation is difficult , while using a rechargeable battery for power supply has a shorter battery life, and the use of power supply equipment inside the water supply and drainage pipes has a greater safety hazard and poor practicability
