Pipeline dredging device

Abstract

The invention provides a pipeline dredging device, and belongs to the structural field of urban sewer line dredging equipment. The pipeline dredging device comprises a tail bearing hydraulic locating seat and a front bearing hydraulic locating seat, a front central protrusion of the tail bearing hydraulic locating seat is connected with a rear central protrusion of the front bearing hydraulic locating seat through a single-acting linear hydraulic cylinder, and the annular face of the front end of the front bearing hydraulic locating seat is connected with the annular face of the rear end of a sealed box in a fastening mode. A single-acting hydraulic cylinder is arranged on a central axis of the sealed box, a base of the single-acting hydraulic cylinder is connected with the sealed box in a fastening mode, the piston end of the single-acting hydraulic cylinder is connected with a base of a servo motor in a fastening mode, the servo motor is arranged in the sealed box, the output end of the servo motor is connected with the rear end of a coupling, and connecting rods are evenly distributed on the outer annular face of the front end of the coupling. The front end of the sealed box is covered with an end cover, an opening is formed in the center of the end cover, a bearing is arranged on the inner ring face of the end cover, the outer ring face of the rear end of a tool rest is born on the inner ring face of the bearing, and cleaning blades are evenly distributed on the outer round face of the front end of the tool rest.

Description

technical field [0001] The invention relates to the structural technical field of dredging equipment for urban sewage pipelines, in particular to a pipeline dredging device. Background technique [0002] There are mainly two types of reasons for the problem of pipeline blockage. One is that domestic sewage contains a large amount of substances that are easy to scale, such as calcium salts and grease. The second reason is that these stains are mixed with sediment, urine or oil and other substances in the water, making domestic sewage easier to scale than domestic water. As a result, soon after the new building is used, the cross-section of the pipeline begins to decrease and the flow rate drops , Poor circulation and finally completely blocked. At this time, measures must be taken to clean up. [0003] The workload of sewer dredging projects is generally relatively large, and the construction area is wide, which is one of the main cleaning fields. The existing technology a...

The second reason is that these stains are mixed with sediment, urine or oil and other substances in the water, making domestic sewage easier to scale than domestic water. As a result, soon after the new building is used, the cross-section of the pipeline begins to decrease and the flow rate drops , Poor circulation and finally completely blocked

The existing technology adopts the method of workers entering the sewer, dredging with a hand-held machine or replacing all the pipes with new ones. This is not only time-consuming, labor-intensive, and material-intensive, but also the sewer will still be blocked after a cycle, causing the problem to reappear
