Description

Technical Field

[0001] This utility model relates to the field of municipal pipeline engineering construction technology, specifically to a pipeline dredging tool for working in a limited space. Background Technology

[0002] In existing municipal engineering projects, the trend of old pipeline clogging is becoming increasingly serious, especially in pipelines located in old urban areas or rural villages, where the work routes are long and the working width is narrow. Traditional pipeline dredging usually involves professional dredging teams equipped with specialized vacuum pump trucks and high-pressure water guns. However, the equipment is bulky and clearly insufficient in limited working spaces. While some simple hand tools can enter the pipes, their dredging efficiency is extremely low, and it is difficult to remove silt deep within the pipes. To complete pipeline dredging work smoothly and efficiently, it is necessary to research a pipeline dredging tool suitable for use in limited working spaces. Utility Model Content

[0003] To address the problem of limited working space in pipeline dredging, this utility model provides a pipeline dredging tool for limited working space. This tool is simple in composition, easy to use, and has a fast construction efficiency.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is: a pipeline dredging tool for limited working space, characterized in that: it includes a spindle-shaped structure composed of a main rib, a stabilizing rib, a circular steel plate, and end steel plates. The circular steel plate is located between the two end steel plates, serving as the contact surface for pipeline dredging, and has water passage holes on it to reduce dredging resistance. The main rib passes through the circular steel plate and the end steel plates, and the main ribs at both ends are ring-shaped and serve as tension supports. The stabilizing rib consists of multiple ribs, evenly distributed around the central main rib, with both ends connected to the end steel plates and the circular steel plate, respectively.

[0005] The main reinforcement is made of φ10 round steel, and the stabilizing reinforcement is made of φ8 round steel. Eight stabilizing reinforcements are evenly arranged along the circumference on each side.

[0006] Both the circular steel plate and the end steel plate are made of 5mm thick steel plate. The diameter of the circular steel plate is slightly smaller than that of the pipe being dredged, and the diameter of the end steel plate is 1 / 10 to 1 / 8 of the diameter of the circular steel plate.

[0007] The diameter of the water passage is 3 to 5 cm.

[0008] This utility model provides a pipeline dredging tool for limited working space, which can effectively carry out pipeline dredging work in situations where the working space is limited, reduce operating costs, improve construction efficiency, and is easy to operate.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] Example 1

[0014] like Figure 1 The illustrated pipeline dredging tool for limited working space includes a spindle-shaped structure composed of a main rib 1, a stabilizing rib 2, a circular steel plate 3, and end steel plates 5. The circular steel plate 3 is located between the two end steel plates 5, serving as the contact surface for pipeline dredging, and has water passage holes 4 for reducing dredging resistance. The main rib 1 passes through the circular steel plate 3 and the end steel plates 5, and the main rib 1 at both ends is a pull ring shape that provides tension. The stabilizing rib 2 consists of multiple ribs evenly distributed around the central main rib 1, with both ends connected to the end steel plates 5 and the circular steel plate 3, respectively.

[0015] The main rib 1 is made of φ10 round steel, and the stabilizing rib 2 is made of φ8 round steel. Eight stabilizing ribs 2 are evenly arranged along the circumference on each side.

[0016] Both the circular steel plate 3 and the end steel plate 5 are made of 5mm thick steel plates. The diameter of the circular steel plate 3 is slightly smaller than that of the pipe being dredged, and the diameter of the end steel plate 5 is 1 / 9 of the diameter of the circular steel plate 3.

[0017] The diameter of the water passage 4 is 4cm.

[0018] like Figure 2 As shown, the specific operating steps of this utility model are as follows:

[0019] First, according to the tool design drawings and technical parameters, the main rib 1, the stabilizing rib 2, the circular steel plate 3, and the end steel plate 5 are connected to form the tool.

[0020] Secondly, place a winch 6 at each end of the wellhead of the section to be dredged, and connect the two ends of the dredging tool 7 of this utility model to the winches 6 at both ends by hooks and wire ropes.

[0021] Next, start the power unit 8, and use the winches 6 at both ends as follows: Figure 2 The middle arrow indicates the direction of the back-and-forth dragging motion to unclog and clear the silt and debris from the pipe, moving it into the inspection wells at both ends. Figure 2 As shown.

[0022] Finally, the silt and debris inside the inspection well were removed and discharged.
