Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipeline dredging, in particular to a drainage pipeline dredging auxiliary device. Background Art

[0002] Due to construction quality, design planning, operation and maintenance management, and environmental factors, urban drainage pipe networks produce functional defects such as sedimentation during long-term operation. In response to this situation, municipal pipeline maintenance units usually use dredging equipment to dredge pipeline deposits. The commonly used dredging method for pipeline deposits is high-pressure water jet dredging. Specifically, a high-pressure water pipe is placed into the target pipeline by a dredging vehicle, and the high-pressure water flow of the nozzle is used to clean and disturb the sediment at the bottom of the pipeline. Then, the sediment accumulated in the well chamber is cleaned in combination with the sewage suction function of the dredging vehicle or a long-handled tool, thereby achieving the purpose of cleaning and maintenance of urban drainage pipes. However, when the high-pressure water pipe of the dredging vehicle is working, it often rubs against the edge of the well ring of the municipal manhole, causing serious wear of the high-pressure water pipe, which not only reduces the working life of the high-pressure water pipe, but also poses a great safety hazard. Therefore, it is very necessary to take corresponding auxiliary measures to solve such problems, so the utility model is proposed. Utility Model Content

[0027] The positioning assembly includes a square tube 7 and an adjustment assembly. The square tube 7 is slidably connected to the crossbar 2. Through holes are provided on the two opposite side walls of the square tube 7. One end of the crossbar 2 passes through the two through holes. An adjustment assembly is provided on the side of the square tube 7 close to the pulley 4. The adjustment assembly includes a circular positioning plate 8. A through hole is provided at the center of the positioning plate 8. A sleeve 9 is welded on the side wall of the through hole close to the square tube 7. The sleeve 9 is threadedly connected to the crossbar 2. A thread groove is provided inside the sleeve 9. The crossbar 2 is provided with a thread 10 corresponding to the thread groove, which is convenient for adjusting the distance between the square tube 7 and the support rod 1. A handle 11 is welded on the other side wall of the positioning plate 8 to facilitate the rotation of the positioning plate 8.

[0028] The top of the vertical rod 3 is welded to the bottom of the support rod 1, the vertical rod 3 is perpendicular to the cross rod 2, a fixed connecting rod 12 is provided between the cross rod 2 and the vertical rod 3, and the two ends of the fixed connecting rod 12 are respectively welded to the cross rod 2 and the vertical rod 3. The lengths of the support rod 1 and the cross rod 2 are both greater than the wellhead diameter of the manhole, and the vertical distance between the two cross rods 2 is less than the wellhead radius of the manhole.

[0029] The support rod 1, cross bar 2, vertical rod 3 and fixed connecting rod 12 in this embodiment are all made of HRB400 steel bars. The diameter of the support rod 1 is 16mm and the length is 950mm; the diameter of the cross bar 2 is 16mm and the length is 750mm; the diameter of the vertical rod 3 is 10mm and the length is 250mm; the diameter of the fixed connecting rod 12 is 10mm and the length is 100mm.
