However, with the continuous increase in the use of steel pipes, the problem of their recycling management has gradually become prominent, becoming a major problem that the industry needs to solve urgently.

[0003] In actual construction sites, steel pipes are mostly used in a rental manner. Although this method saves costs, it also brings new challenges to the maintenance and management of steel pipes. Steel pipes are exposed to wind, rain and sun for a long time on the construction site, which will inevitably produce rust. Rust will not only reduce the strength and stability of the steel pipe and affect the safety of subsequent use, but also excessive rust will affect the appearance of the steel pipe and reduce its market value. In addition, the steel pipe will inevitably be contaminated with impurities such as dirt and cement during use, which not only increases the weight of the steel pipe, but also creates obstacles to the reuse of the steel pipe. Therefore, a surface cleaning device for steel pipe recycling is urgently needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-3 As shown, the utility model provides a surface cleaning device for recycling steel pipes, including a shell 10, wherein a steel pipe introduction component 20 and a steel pipe cleaning component 30 are respectively arranged inside the shell 10. Before recycling the steel pipe, the staff only needs to put the steel pipe into the entrance of the shell 10, and the steel pipe guide component inside it will guide the steel pipe to pass through the entire device. When the steel pipe passes through the steel pipe cleaning component 30, the roller brush 32 will brush off stubborn impurities such as rust, soil and cement on the surface of the steel pipe. The through hole 322 thereon allows the brushed impurities to fall smoothly to the bottom of the steel pipe cleaning component 30, and finally be discharged from the device through the dust removal port 312, so as to keep the inside of the device clean. This design not only improves the efficiency of steel pipe cleaning, but also greatly enhances the safety and market value of steel pipe recycling.

[0029] In this embodiment, a bracket 11 is provided at the bottom of the outer shell 10, and an inlet and an outlet are respectively provided on the front and rear sides of the outer shell 10. The inlet is funnel-shaped, which is convenient for guiding the inserted steel pipe, and at the same time can constrain the steel pipe to pass just between the driving wheel 21 and the driven wheel 23, so that the steel pipe introduction component 20 can apply force to it to move it. A sewage outlet 12 is opened at the bottom of the outer shell 10.

[0030] like Figure 2 As shown, the steel pipe introduction assembly 20 has two groups, which are respectively arranged on the bottom wall of the shell 10 near the front and rear outlets.

[0031] Specifically, the steel pipe introduction assembly 20 includes a driving wheel 21, a driven wheel 23 and a stepper motor 22. The driving wheel 21 and the driven wheel 23 are arranged on the bottom wall along the central axis of the shell 10 as a symmetrical axis. The stepper motor 22 is arranged at the bottom of the shell 10, and its output shaft passes through the bottom wall of the shell 10 and is connected to the driving wheel 21. When the steel pipe is placed between the driving wheel 21 and the driven wheel 23, the stepper motor 22 drives the driving wheel 21 to rotate, and the friction between the driving wheel 21 and the steel pipe drives the steel pipe to move backward. The driven wheel 23 plays a role of cooperating clamping, so that the steel pipe moves backward stably.

[0032] As a preferred embodiment, the side surface of the driving wheel 21 is a concave surface, and an anti-skid layer is arranged on the concave surface. The driven wheel 23 has the same concave surface and anti-skid layer. The anti-skid layer can be provided with cross-shaped anti-skid patterns, or a number of rubber strips can be pasted. The concave surface can make the steel pipe clamping more stable, avoiding the situation where the steel pipe moves in the up and down directions of the steel pipe introduction assembly 20, which is inconvenient for the steel pipe to move. The anti-skid layer is used to increase the friction between the driving wheel 21 and the driven wheel 23 and the steel pipe, so as to facilitate better force to move it backward.

[0033] like Figure 3 As shown, the steel pipe cleaning assembly 30 includes a mounting seat 31 and a roller brush 32. The mounting seat 31 is arranged at the top of the sewage outlet 12. A dust removal port 312 is arranged at the bottom of the mounting seat 31. The dust removal port 312 penetrates the sewage outlet 12 and extends to the outside of the dust removal port 312. The roller brush 32 is rotatably arranged on the top of the mounting seat 31. A through hole 322 is arranged on the roller brush 32. When the steel pipe passes through the roller brush 32, the roller brush 32 fully brushes off the impurities on the surface of the steel pipe. The brushed impurities fall to the dust removal port 312 through the through hole 322 and finally flow to the ground.

[0034] As a preferred embodiment, a storage rack formed by welding a number of beams is provided at the bottom of the bracket 11, and a recovery trough is placed on the storage rack. The opening size of the recovery trough is larger than the size of the dust removal port 312. Since rusty iron filings will seriously pollute the environment, the brushed impurities are collected through the recovery trough and finally processed in a centralized manner to avoid polluting the environment.

[0035] like Figure 4-6 As shown, the mounting seat 31 includes enclosures 311 arranged on the left and right sides, a dust removal port 312 is arranged at the bottom of the mounting seat 31, two pairs of first guide rollers 314 are arranged on the left and right sides of the mounting seat 31 at the front and rear ends of the enclosures 311, a servo motor 316 is arranged on the front right side of the mounting seat 31, and roller brackets 313 are symmetrically arranged on the top of the mounting seat 31 near the servo motor 316 along the central axis direction of the mounting seat 31, and second guide rollers 315 are arranged on the opposite sides of the two roller brackets 313 near the top side, and a transmission gear 317 is arranged on the rotating shaft of the first guide roller 314 near the servo motor 316, and the transmission gear 317 is connected to the servo motor 316 through a chain.

[0036] like Figure 3 and Figure 7 As shown, four groups of bristles 321 are equally divided on the inner side of the roller brush 32, and a plurality of through holes 322 are provided between any two groups of bristles 321. The outer surface of the roller brush 32 is provided with a first track 333 and a second track 334 along the front and rear ends of the through holes 322, respectively, and a circle of flange 335 is provided on the front side of the first track 333.

[0037] It should be noted that the bristles 321 are steel wire bristles 321. The rust, solidified cement and mud on the surface of the steel pipe are very firmly attached. The cleaning effect of a conventional hard-bristle brush is poor, while the steel wire brush has a suitable hardness and can effectively remove the above-mentioned stubborn impurities.

[0038] Further, when the roller brush 32 is disposed on the top of the mounting seat 31 , the first guide roller 314 is engaged with the first track 333 and the second track 334 respectively, and the second guide roller 315 is in contact with the front side of the flange 335 .

[0039] Specifically, when the servo motor 316 is started, the adjacent first guide roller 314 is driven by the chain to start rotating, and the first guide roller 314 contacts the first track 333 on the outer side of the roller brush 32, and the roller brush 32 is caused to move relative to each other through friction. At the same time, the four first guide rollers 314 work together to provide rolling support for the roller brush 32 to ensure smooth and unobstructed operation. The second guide roller 315 arranged on the front side of the mounting seat 31 conflicts with the flange 335 on the front side of the roller brush 32, thereby preventing the four first guide rollers 314 from rolling on the first track 333. The roller brush 32 moves forward and backward on the second track 334, thereby increasing the rolling stability of the roller brush 32. During the cleaning process, the wire brush on the roller brush 32 effectively brushes away impurities on the surface of the steel pipe. These impurities flow into the dust removal port 312 through the through hole 322 on the roller brush 32, and finally flow into the recovery tank, thereby realizing the centralized collection and treatment of impurities. In addition, the enclosures 311 on the left and right sides of the mounting seat 31 prevent the brushed impurities from flowing out from both sides of the roller brush 32, thereby preventing the accumulation of impurities inside the outer shell 10 and maintaining the cleanliness and efficiency of the entire cleaning device.

[0040] Specifically, the working principle of the surface cleaning device for recycling steel pipes is as follows: when in use, first put the steel pipe to be cleaned into the entrance of the shell 10 to ensure that the steel pipe is exactly located between the driving wheel 21 and the driven wheel 23. Then, the stepper motor 22 rotates to drive the driving wheel 21 to rotate, thereby driving the steel pipe to move toward the steel pipe cleaning component 30. At the same time, the servo motor 316 drives the adjacent first guide roller 314 to start rotating through the chain. The first guide roller 314 conflicts with the first track 333 on the outer side of the roller brush 32, causing it to produce relative rotational motion. During this process, the other three first guide rollers 314 work together to provide stable support for the roller brush 32. At the same time, the mounting base 3 The second guide roller 315 on the front side contacts with the flange 335 on the front side of the roller brush 32, ensuring the stability of the roller brush 32 in the front-to-back direction, making its rotation smoother. As the roller brush 32 rotates, the bristles 321 thereon rotate and rub against the outer surface of the steel pipe, effectively brushing away impurities attached to the surface of the steel pipe. These impurities then fall through the through holes 322 on the roller brush 32 to the dust removal port 312, and finally flow into the recovery tank, realizing the centralized collection and treatment of impurities. Through the above structure, the problem that the prior art does not provide effective removal of impurities such as rust, soil and cement on the steel pipe when recycling the steel pipe, resulting in poor strength and stability, increased weight and thus affecting the reuse of the steel pipe is solved.

[0041] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
