Transverse sewer dredging system and dredging method

Abstract

The invention discloses a transverse sewer dredging system and dredging method. The transverse sewer dredging system comprises a dredging device, a guiding device and a hoisting device, wherein the dredging device comprises a shell, a twisting head, a power structure and a walking structure. The shell comprises a shell body, an upper cover plate and a mud fending lateral plate; the walking structure comprises two sets of chain wheels, two sets of chains, antiskid teeth and two rotary shafts, the power structure comprises a double-head hydraulic motor, a reduction gear and a hydraulic pipe connector, the guiding device is used for guiding the dredging device in entering or exiting from a transverse sewer, and the hoisting device is used for hoisting the dredging device into or out of an inspection well. By means of the transverse sewer dredging system, manually descending the well to conduct operation is not needed anymore, and the transverse sewer dredging system and dredging method have the advantages that dismantling is convenient, carrying is safe, the service life is long, the installation and maintenance are convenient, and the system is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of pipeline dredging machinery, in particular to a horizontal sewer dredging system and a dredging method. Background technique [0002] At present, the dredging of sewer pipes is mainly done manually. It is cleaned by wearing scrapers or spraying water guns. The construction environment is not only dirty, but also dangerous. In the case of blockage, these two methods cannot be realized. Of course, there is also a trolley-type pipeline cleaning device. The patent with the authorized announcement number of CN 103352513 B discloses a sewer dredging machine, which solves the problem of manual downhole operation, but its walking device is a wheel-shaped walking device, and it is difficult to walk once it gets stuck in the mud. , the reamer blade that it is provided with is easily damaged when running into stones or construction waste in addition. The patent with the authorized announcement number of CN 20108997...

Problems solved by technology

[0002] At present, the dredging of sewer pipes is mainly done manually. It is cleaned by wearing a scraper or spraying with a water gun. The construction environment is not only dirty, but also dangerous. In the case of blockage, these two methods cannot be realized.

Of course, there is also a trolley-type pipeline cleaning device. The patent with the authorized announcement number of CN 103352513 B discloses a sewer dredging machine, which solves the problem of manual downhole operation, but its walking device is a wheel-shaped walking device, and it is difficult to walk once it gets stuck in the mud. , in addition, the reamer blade is easily damaged when encountering stones or construction waste

The patent with authorized notification number CN 201089976Y discloses an automatic sewer dredging machine, which solves the problem of subsidence through crawler belts, and has a large power, but it still needs to be manually descended into the horizontal pipe through the vertical inspection shaft and retrieved. operation, there is still a certain risk
