Description

Technical Field

[0001] This invention relates to the field of PCCP pipe production equipment technology, and in particular to an automatic slag removal device for PCCP pipe spigot rings. Background Technology

[0002] PCCP (Prestressed Concrete Cylinder Pipe) is a high-performance water transmission pipeline widely used in water conservancy projects, municipal water supply and drainage, and other fields. PCCP pipe is a composite structure pipeline composed of a steel cylinder, concrete, and prestressed steel wire. It combines the compressive strength of concrete with the tensile strength of steel, and enhances the overall strength and durability of the pipeline through prestressing technology. One end of the PCCP pipe has an exposed spigot, and the other end has a spigot for insertion into adjacent PCCP pipes. PCCP pipes require continuous spigot connection during installation. Laying down and cleaning the pipeline are crucial steps in the production and maintenance of PCCP pipes. During factory production or repair, PCCP pipes are usually in an upright position; they need to be turned to a horizontal position for subsequent installation or repair operations. Furthermore, to ensure the sealing and reliability of the pipeline connection, the exposed outer wall of the PCCP pipe spigot needs to be thoroughly cleaned to remove surface impurities, dust, and residues. Traditional PCCP pipe placement and cleaning methods have the following problems: 1. Complexity and inefficiency of manual cleaning: The traditional method involves using a tilting device to turn the vertical PCCP pipe into a horizontal position, and then manually cleaning the exposed outer wall of the spigot. Since PCCP pipes typically have diameters ranging from 500 mm to 3200 mm, manual cleaning is complex and tedious, requiring work at a higher position, resulting in lower safety and efficiency. 2. Inconsistent cleaning quality: Manual cleaning makes it difficult to guarantee consistent cleaning quality. Operator fatigue or negligence can easily lead to missed areas, resulting in impurities remaining on the outer wall of the spigot and affecting the sealing of the pipe connection. 3. High labor intensity: Manual cleaning requires a significant amount of physical strength and time, especially when handling large-diameter PCCP pipes, where labor intensity increases significantly, easily leading to worker fatigue and further reducing work efficiency and quality.

[0003] In view of the above problems, existing methods for placing and cleaning PCCP pipes can no longer meet the high requirements of modern water conservancy projects and municipal water supply and drainage projects for pipeline quality and construction efficiency. Therefore, it is necessary to invent a device that facilitates the automatic laying of PCCP pipes and simultaneously achieves slag removal from the PCCP pipe spigot ring, in order to solve the problems existing in the prior art. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cleaning device for PCCP pipe spigot rings, addressing the aforementioned problems and resolving the technical issues of low efficiency, high labor intensity, and low safety associated with manual cleaning during the process of laying down PCCP pipes and cleaning spigot rings in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic slag removal device for PCCP pipe spigot rings, characterized in that: it includes...

The first driving device drives the reverse double-ended lead screw to rotate, and causes the two rolling wheel sets to move towards or away from each other.

[0009] Furthermore, the lower part of the roller assembly is provided with a longitudinal slide rail, which is slidably mounted on the transverse slide rail via a dovetail connector.

[0012] Furthermore, the stacking device includes a jack and a top plate. The jack is embedded in the bottom support frame, and the top plate is installed at the extended end of the jack. The jack pushes the PCCP pipe to separate from the bottom support frame through the top plate and then retracts.

The lower part of the rolling frame device is provided with a spacing adjustment device. Through the reverse double-headed screw assembly and the first driving device, the spacing between the rolling wheel group can be flexibly adjusted to adapt to PCCP pipes of different diameters.

[0029] In this embodiment, the roller assembly 21 includes a slide block 211, which is slidably mounted on a longitudinal slide rail 23. A plurality of coaxially arranged rollers 212 are alternately arranged on the slide block 211, and the rollers 212 are linked through a rotating shaft 213. The roller assembly 21 is equipped with a second driving device 214, which can drive the rotating shaft 213 to rotate.

The movable housing 32 is slidably mounted on the composite slide rail 31. The third drive device 33 is mounted on the movable housing 32, and a gear that meshes with the rack is provided at the output end of the third drive device 33. The fourth drive device 34 is mounted outside the movable housing 32, and the output end of the fourth drive device 34 drives the brush body 35 to rotate.

[0033] The working principle of this embodiment can be referred to the following steps: 1. Initially, depending on the size of the PCCP pipe 5, the first drive device 222 drives the reverse double-headed screw 223 to rotate, so that the two rolling wheel groups 21 move towards or away from each other to the appropriate position, and then the first drive device 222 stops and locks; then the laying device 1 is in the upright state. At this time, the rolling frame device 2 slides down due to gravity and stops when the middle of the connecting slide rod 24 abuts against the upper end surface of the top plate 42. 2. The PCCP pipe 5 is placed on the bottom support 111 by hoisting, with the spigot ring 51 facing upward and the side wall of the PCCP pipe 5 in contact with the two rollers 212; by retracting the push rod 13, the folding frame 11 is folded down, so that the side support 112 is placed horizontally, and at this time the weight of the PCCP pipe 5 presses on the roller group 21. 3. When the stacking device 3 is working, the jack 41 stacks out, so that the top plate 42 abuts against the end of the PCCP pipe 5 and the middle of the connecting slide rod 24, so that the end of the PCCP pipe 5 is separated from the bottom support frame 111; then the jack 41 is retracted, and the roller 212 can be driven to rotate through the second drive device 214. At the same time, the roller 212 also drives the PCCP pipe 5 to rotate in the circumferential direction. 4. The slag-cleaning brush device 4 operates. The third drive device 33 drives the movable housing 32 to move closer to the PCCP pipe 5, and the fourth drive device 34 drives the brush body 35. When the brush body 35 can brush the outer circumference of the insertion ring 51 of the PCCP pipe 5, the third drive device 33 stops and locks its position, so that the brush body 35 can brush the outer circumference of the rotating insertion ring 51. At this time, due to the heavy pressure of the PCCP pipe 5, the friction between the longitudinal slide rail 23 and the slide seat 211 will not cause relative sliding. Then the PCCP pipe 5 is lifted away. Repeating the above actions can achieve efficient PCCP pipe 5 laying down and slag cleaning of the insertion ring 51.

[0034] The above description is a detailed description of the preferred embodiments of the present invention. However, the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications made under the technical spirit of the present invention should fall within the patent scope covered by the present invention.
