Description

Technical Field

[0001] This invention relates to the field of PE pipe technology, specifically to a PE pipe weld joint cleaning device. Background Technology

[0002] PE is polyethylene plastic, the most basic type of plastic, with excellent resistance to most household and industrial chemicals. PE pipes are generally used for municipal sewage discharge pipelines. During the pipeline laying and connection process, capacitor welding is generally used to connect the ends of two PE pipes into a sleeve. Before welding, the surface of the PE pipe needs to be cleaned. However, the existing cleaning methods all involve manual cleaning with brushes, which not only increases the workload but also reduces the cleaning efficiency. Therefore, we propose a PE pipe weld joint cleaning device. Summary of the Invention

[0003] The purpose of this invention is to provide a PE pipe weld joint cleaning device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a PE pipe weld joint cleaning device, comprising a base, an electric telescopic rod fixedly connected to the right front end of the top of the base, and a second toothed plate fixedly connected to the telescopic end of the electric telescopic rod, a transmission tooth engaged with the back of the second toothed plate, and a transmission rod engaged with the back of the transmission tooth, a connecting plate fixedly connected to the right side of the transmission rod, a baffle fixedly connected to the right side of the connecting plate, and a sleeve fixedly connected to the middle of the right side of the baffle, a screw movably connected to the inner surface of the sleeve, and a threaded sleeve threadedly connected to the outer surface of the screw, and a plurality of equidistantly distributed first adjusting rods movably connected to the outer side of the threaded sleeve, and an adjusting frame movably connected to the end of the first adjusting rod.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes an external hexagonal wrench inserted into a hexagonal hole to tighten a screw, which moves a threaded sleeve. With the cooperation of the sleeve, third sliding groove, first adjusting rod, second adjusting rod, and adjusting frame, multiple second cleaning plates can simultaneously expand outwards or contract inwards, bringing the brushes on the surface of the second cleaning plates into contact with the inner wall of the pipe. Adjusting the first cleaning plate, with the cooperation of gears, a first slider, and a first sliding groove, allows two first toothed plates to move simultaneously inwards or outwards, bringing the brushes on the surface of the first cleaning plate into contact with the outer wall of the pipe. Then, screwing the screw into the corresponding pre-drilled hole fixes the position of the first toothed plate. Controlling the extension and retraction of the electric telescopic rod, with the cooperation of the second slider and second sliding groove, drives the second toothed plates to reciprocate. With the cooperation of transmission gears, a U-shaped frame, a roller, a limiting groove, and an auxiliary frame, the transmission rod can reciprocate and continuously rotate in one direction, allowing the brushes to simultaneously clean the inner and outer surfaces of the pipe. During this process, the fan blades blow away the dust generated during cleaning, further improving the welding effect. Attached Figure Description
