Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel pipe cleaning technology, and more specifically, it relates to a surface cleaning device for building steel pipes. Background Technology
[0002] After the outer wall of straight seam steel pipes used in construction is covered with dirt such as oxide scale, rust, cement lumps, and oil stains, it is mostly necessary to clean the dirt with a wire brush type outer wall cleaning device. During cleaning, the active V-shaped conveyor roller will drive the steel pipe forward at a constant speed while rotating around its own axis. After the steel pipe enters the rust removal unit, the high-speed rotating wire brush polishes the outer wall of the steel pipe in multiple directions at the same time, removing rust and oxide scale. The cleaned steel pipe is sent out from the discharge port and falls into the collection area through the buffer frame.
[0003] For example, CN220127082U discloses a rust removal device for building steel pipes, relating to the field of steel pipe rust removal technology. It includes a working box, with a first hydraulic cylinder at the bottom of the working box's inner cavity. A placement platform is provided at the piston end of the first hydraulic cylinder. Storage cylinders are fixedly connected to both sides of the working box's inner cavity. Second servo motors are provided on both sides of the working box, with their output ends extending into the storage cylinders and equipped with rotating disks. Two first electric telescopic rods are fixedly connected to one side of each rotating disk. This rust removal device for building steel pipes, by incorporating a support plate, a fixed column, and a second hydraulic cylinder, can limit the movement of the building steel pipe without obstructing the areas on the pipe surface that need cleaning. Simultaneously, a third hydraulic cylinder and a clamping plate can fix the outer side of the building steel pipe, allowing the brush head to clean the inside of the pipe and remove rust.
[0004] Based on the above, in order to reduce the wear of cement lumps on the wire brush, it is necessary to clean the large cement lumps attached to the surface of the steel pipe in advance before sending the steel pipe into the cleaning device, which takes a long time and affects the cleaning efficiency of the steel pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention can simultaneously complete the scraping of large cement lumps, rust and scale removal, dust and debris sweeping, and dust and debris collection during steel pipe conveying. It eliminates the need for manual pre-cleaning of cement lumps required in traditional cleaning methods, significantly simplifying the operation process, shortening overall cleaning time, and significantly improving the efficiency of continuous steel pipe cleaning. The conical wear-resistant cleaning plate can be adjusted at an adjustable angle to flexibly adjust the fit according to different pipe diameters, stably achieving efficient pre-cleaning of stubborn cement lumps and hard dirt on the outer wall of the steel pipe. This effectively avoids problems such as increased wear on the wire brush, equipment jamming, or reduced cleaning effect caused by large impurities entering the subsequent rust removal stage. It also improves the versatility and adaptability of the device, extends the service life of core cleaning components, and reduces equipment maintenance costs and consumable costs. By changing the frequency and tightening the elastic element, the powder cleaning brush can always maintain a stable fit with the outer wall of the steel pipe, achieving self-adaptive clamping of the powder cleaning brush. This ensures effective cleaning of fine rust powder, debris, and dust remaining after grinding. The dustproof mounting box provides sealed protection for the electric push rod and cylinder, effectively preventing dust and rust from entering the internal components of the power unit, reducing the probability of failure, improving the stability and durability of equipment operation, and extending the overall service life of the equipment. It can collect scraped clumps, rust debris generated during grinding, and swept dust in real time throughout the cleaning operation. Through negative pressure suction and filtration separation, dust is effectively suppressed, preventing dust from spreading and polluting the working environment. The debris collection trough adopts an inclined bottom design with a sealing plug structure, which facilitates quick and convenient discharge of collected impurities and reduces cleaning difficulty.

[0025] The specific usage and function of this embodiment are as follows: When cleaning the surface dirt of building steel pipes, the steel pipe is placed above the active V-shaped conveying roller set in the main body 1 of the device. The active V-shaped conveying roller will continuously convey the steel pipe. The angle of the wear-resistant cleaning plate 4 is adjusted according to the diameter of the steel pipe, so that the wear-resistant cleaning plate 4 swings along the limiting connecting seat 3 until it is in contact with the surface of the steel pipe.
