Description

Technical Field

[0001] The invention relates to a steel pipe surface cleaning device, in particular to a steel pipe surface cleaning device for construction engineering, and belongs to the technical field of steel pipe surface cleaning. Background Art

[0002] Scaffolding steel pipes are a common support structure used in construction projects. They are often used to construct temporary support structures to provide a safe working platform for construction workers. They also serve as material handling channels, facilitating the vertical and horizontal transportation of construction materials and improving construction efficiency. During use, scaffolding steel pipes inevitably become contaminated with various dirt, such as rust, sand, and concrete debris. This dirt not only increases the overall weight of the steel pipes and makes scaffolding assembly more difficult, but also accelerates corrosion, reducing their strength and service life, and even affecting construction safety.

[0003] The Chinese patent, entitled "Equipment for Removing Concrete from Steel Pipe Surfaces" (patent number ZL202310693819.X), discloses a technology for removing concrete from steel pipe surfaces. The technology utilizes the rotation of the rotating inner ring inside the striking chassis to allow the striking swing arms distributed in the internal ring array to rotate. During rotation, when the striking swing arm rotates and moves to the top position, the gravity of the bottom jogging roller causes the jogging roller and the striking swing arm to drop as a whole, producing a striking effect on the surface of the passing steel pipe, and causing the concrete on the surface to fall off through continuous striking. However, although the device can achieve a cleaning effect on the surface of the steel pipe, it mainly uses striking to remove the concrete attached to the surface of the steel pipe. Not only is the striking range limited and the cleaning effect poor, but also, when in use, the steel pipes need to be placed one by one according to the holes on the feed disc, resulting in low operating efficiency.

[0004] The Chinese patent, entitled "Equipment for Removing Concrete from the Surface of a Steel Pipe" (publication number CN222306726U), discloses a surface cleaning technology for steel pipes. Through the coordinated work of a stepper motor and a servo motor, automatic feeding and surface cleaning of the steel pipe are achieved. The rotational friction of the bristles on the outer surface of the steel pipe can effectively remove stubborn impurities such as rust, cement, and mud, greatly improving the cleaning efficiency. However, although the equipment can automatically load materials, it still has the problem of low loading operation efficiency, that is, it can only load and clean one steel pipe at a time. For this reason, a surface cleaning equipment for steel pipes for construction projects is proposed. Summary of the Invention

[0076] When the present invention is working: the whole device is installed to the designated position according to actual needs. When the surface of the scaffolding steel pipe needs to be cleaned, first, the piston rod of the second cylinder 83 drives the connecting bracket 84 to move, and the moving connecting bracket 84 drives the annular door body 81 to move.

When the steel pipe moves to a high place, gravity is used to make it fall, so that the steel pipe rolls, collides and rubs in the outer support tube 101, and then the mutual collision and friction between the steel pipes can be used to grind and remove the dirt attached to its surface, and then the ground dirt is filtered out by the filter inner tube 103, and the dirt is discharged to the outside of the outer support tube 101 through the provided discharge port 86.

[0078] When the surface of the steel pipe needs to be further cleaned, the external water source is pumped out through the spray pump 602 using the water pumping pipe 605 and injected into the spray rack 603. Then, the water in the spray rack 603 is sprayed into the interior of the outer support tube 101 through the spray head 604, so that the surface of the steel pipe can be rinsed with the sprayed water to remove the dust attached to its surface. The sprayed water can also be used to suppress the dust generated during the friction process to avoid environmental pollution.

[0079] When it is necessary to clean the inner wall of the steel pipe, first use the connecting ear 708 to install the inner wall cleaning component 7 to one side of the outer support tube 101, and then use the piston rod of the first cylinder 303 to push the connecting plate 302 to move, and the moving connecting plate 302 drives the central axis 301 to move. The moving central axis 301 slides in the inner bracket 305 and drives the second connecting arm 402 to move. The moving second connecting arm 402 cooperates with the second connecting arm 402 to drive the inner support plate 403 to move. At the same time, the other end of the second connecting arm 402 can slide by using the slide groove 405 through the set slide 404; then use the moving inner support plate 403 to drive the support airbag 504 to expand, so that the expanded support airbag 504 can be used to squeeze the steel pipe, and then cooperate with the rotating bundle tube ring frame 102 to press the steel pipes one by one into the groove of the bundle tube ring frame 102, so that the steel pipes are distributed in a ring shape in the outer support tube 101. When the air pressure in the supporting airbag 504 is insufficient, air can be injected into the supporting airbag 504 via the air pipe 503 through the small air pump 502 to increase the air pressure in the supporting airbag 504 and enhance the squeezing effect on the steel pipe.

[0080] After the steel pipes are pressed into the grooves of the tube ring frame 102 one by one, the output shaft of the second reduction motor 772 drives the active sprocket 773 to rotate, and the rotating active sprocket 773 drives the transmission chain 775 to rotate. The rotating transmission chain 775 drives the driving screw 702 to rotate by the driven sprocket 774, and the rotating driving screw 702 drives the threaded slider 703 to move by the thread. The moving threaded slider 703 slides in the floor bracket 701 and drives the mounting bracket 704 to move. The moving mounting bracket 704 cooperates with the first reduction motor 705 to drive the cleaning shaft 706 to penetrate the outer support tube 101 and the tube ring frame 102, and insert it into the steel pipe at the bottom of the outer support tube 101, and then drives the cleaning shaft 706 to penetrate the outer support tube 101 and the tube ring frame 102, and insert it into the steel pipe at the bottom of the outer support tube 101, and then drives the cleaning shaft 706 to penetrate the outer support tube 101 and the tube ring frame 102, and insert it into the steel pipe at the bottom of the outer support tube 101, and then drives the cleaning shaft 706 to penetrate the outer support tube 101 and the tube ring frame 102, and then inserts it into the steel pipe at the bottom of the outer support tube 101, and then drives the cleaning shaft 706 to penetrate the outer support tube 101 and the tube ring frame 102 ... 6 rotates, and the rotating cleaning shaft 706 drives the bristles 709 to rotate, so that the bristles 709 can be used to brush the inner wall of the steel pipe, and then the inner wall of the steel pipe can be brushed while the cleaning shaft 706 is inserted into the steel pipe, and the debris that falls off by brushing can be discharged through the provided through hole 85; when the inner wall of a single steel pipe is brushed and cleaned, the threaded slider 703, the mounting bracket 704, the first reduction motor 705 and the cleaning shaft 706 are driven by the second reduction motor 772 to reset as a whole, and then the tumbling drive mechanism 2 drives the filter inner cylinder 103 to drive the bundle tube ring frame 102 to rotate, and the rotating bundle tube ring frame 102 drives the annularly distributed steel pipes to move, so as to replace the steel pipe at the bottom, and then the inner wall of the steel pipes can be brushed and cleaned one by one.

[0081] When it is necessary to unload the cleaned steel pipes, the inner support skeleton mechanism 4 is driven by the inner support driving mechanism 3 to drive the airbag support mechanism 5 to gradually reset. At the same time, the rolling driving mechanism 2 cooperates with the filter inner tube 103 to drive the bundle tube ring frame 102 to rotate, and the steel pipes distributed in a ring shape are gradually gathered to the bottom of the outer support tube 101 for unloading operations.

[0082] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
