Cleaning brush head

Abstract

This application relates to a cleaning brush head, comprising: a brush frame, which is U-shaped, with a connecting part in the middle for connection with a driving component; and a cleaning assembly including multiple cleaning components arranged along the outer periphery of the brush frame. The driving component rotates the brush frame, causing the multiple cleaning components on the brush frame to rotate with it, thereby cleaning channel steel or right-angle steel. Because the brush frame is U-shaped and the cleaning components are arranged along the outer periphery of the brush frame, the shape of the brush frame can be adapted to the shape of the channel steel or right-angle steel, allowing the cleaning components to clean the hard-to-reach areas of the channel steel or right-angle steel. Compared to existing cleaning brush heads, this method saves operators time and effort in completing rust removal and cleaning tasks.

Description

Technical Field

[0001] This application relates to the field of rust removal technology, and in particular to a cleaning brush head. Background Technology

[0002] Steel is widely used in bridge construction due to its high strength, uniform material properties, good plasticity and toughness, and good weldability. Steel truss bridges are composed of truss members and are classified into simply supported steel truss bridges, continuous steel truss bridges, and cantilever steel truss bridges according to the different support methods of the main truss. Before entering service, steel truss bridges undergo rust removal and prevention treatments such as silanization, phosphating, galvanizing, or applying heavy-duty anti-corrosion coatings to extend their service life.

[0003] During the service life of steel trusses, moisture, sunlight, oxides, and pollutants in the atmosphere can cause the protective coating of the steel trusses to deteriorate and fail, leading to rust and reduced structural strength and load-bearing capacity. Therefore, it is necessary to clean the rusted areas and reapply anti-corrosion coating to extend service life. Currently, rust removal is mainly carried out in two ways. First, sandblasting or shot blasting is used, which has good rust removal effect and high efficiency, but the disadvantages are that the equipment is large, generates a lot of dust, and the blasted sand is generally not recyclable, causing environmental pollution and resource waste. Second, manual grinding is performed on the surface of the steel trusses using a handheld angle grinder equipped with a wire brush head or a handheld wire brush.

[0004] However, conventional wire brush heads or handheld wire brushes are difficult to grind and remove rust from the dead corners of steel trusses. The dead corners are not only not cleaned properly, but the operation is also time-consuming and labor-intensive, and there is a possibility of repeated rusting after recoating the anti-corrosion coating. Utility Model Content

[0005] Based on this, this application provides a cleaning brush head to solve the problem that rust removal brush heads in related technologies cannot meet the usage requirements.

[0006] This application provides a cleaning brush head, which includes: a brush holder, which is a U-shaped frame, and a connecting part for connecting with a drive component is provided in the middle of the brush holder; and a cleaning assembly, which includes a plurality of cleaning components arranged along the outer periphery of the brush holder.

[0007] In one embodiment, the brush holder includes a mounting plate and an annular side plate connected to each other. The annular side plate surrounds the outer periphery of the mounting plate, and the mounting plate and the annular side plate together form a U-shaped frame structure. Both the mounting plate and the annular side plate are provided with cleaning components. A connecting part is provided on the mounting plate.

[0008] In one embodiment, the mounting plate includes a first support plate and a first pressure plate connected together, one end of the cleaning member is clamped between the first support plate and the first pressure plate, and the other end of the cleaning member extends out of the first pressure plate; and / or, the annular side plate includes a second support plate and a second pressure plate connected together, one end of the cleaning member is clamped between the second support plate and the second pressure plate, and the other end of the cleaning member extends out of the second pressure plate.

[0009] In one embodiment, when the mounting plate includes a first support plate and a first pressure plate, the connecting portion is a through hole that passes through the first support plate and the first pressure plate.

[0010] In one embodiment, the thickness of the first support plate, the second support plate, the first pressure plate, and the second pressure plate is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0011] In one embodiment, the cleaning assembly includes a plurality of first cleaning units, which are arranged radially spaced along the mounting plate, and each first cleaning unit includes a plurality of cleaning elements arranged circumferentially spaced along the mounting plate; and / or, the cleaning assembly includes a plurality of second cleaning units, which are arranged spaced along the height direction of the annular side plate, and each second cleaning unit includes a plurality of cleaning elements arranged circumferentially spaced along the annular side plate.

[0012] In one embodiment, when the cleaning component includes multiple first cleaning units, the number of cleaning components in each of the multiple first cleaning units is the same, and the cleaning components corresponding to the multiple first cleaning units are arranged linearly; and / or, when the cleaning component includes multiple second cleaning units, the number of cleaning components in each of the multiple second cleaning units is the same, and the cleaning components corresponding to the multiple second cleaning units are arranged linearly.

[0013] In one embodiment, the cleaning component includes a wire brush, the wire brush extending perpendicular to the plane containing the outer wall of the brush holder.

[0014] In one embodiment, the wire brush includes a plurality of bristles, the spacing between adjacent bristles gradually increasing in the direction away from the brush holder.

[0015] In one embodiment, the brush holder is made of metal.

[0016] By applying the technical solution of this application, when cleaning steel trusses such as channel steel or right-angle steel, the cleaning brush head is installed to the drive component through the connecting part of the brush frame. The drive component drives the brush frame to rotate, and the multiple cleaning components on the brush frame can rotate with the brush frame, thereby cleaning the channel steel or right-angle steel. Because the brush frame is U-shaped, and the cleaning components are arranged along the outer periphery of the brush frame, the shape of the brush frame can be adapted to the shape of the channel steel and right-angle steel, allowing the cleaning components to clean the hard-to-reach areas of the channel steel or right-angle steel. Furthermore, the cleaning brush head of this application has a larger cleaning area than existing brush heads, improving cleaning efficiency. Compared to existing cleaning brush heads, this allows operators to complete rust removal and cleaning tasks more quickly and effortlessly. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] See Figure 1 , Figure 1 A schematic diagram of the structure of a cleaning brush head provided in an embodiment of this application is shown. Figure 2 A top view of the cleaning brush head provided in an embodiment of this application is shown. Figure 3 This diagram illustrates the working state of a cleaning brush head provided in an embodiment of this application. One embodiment of this application provides a cleaning brush head, which includes a brush holder 10 and a cleaning assembly 20. The brush holder 10 is a U-shaped frame, and a connecting portion 11 for connection with a drive member 30 is provided in the middle of the brush holder 10. The cleaning assembly 20 includes a plurality of cleaning elements 23 arranged along the outer periphery of the brush holder 10.

[0029] Applying the technical solution of this application, when it is necessary to clean steel trusses such as channel steel or right angle steel 40, the cleaning brush head is installed to the driving component 30 through the connecting part 11 of the brush holder 10. The driving component 30 drives the brush holder 10 to rotate, and the multiple cleaning components 23 on the brush holder 10 can rotate with the brush holder 10, thereby cleaning the channel steel or right angle steel 40. Since the brush holder 10 is a U-shaped frame, the cleaning components 23 are arranged along the outer periphery of the brush holder 10. The form of the brush holder 10 can be adapted to the shape of the channel steel and right angle steel 40, so that the cleaning components 23 can clean the dead corners of the channel steel or right angle steel 40.

[0030] By arranging the brush holder 10 into a U-shaped structure, the cleaning brush head of this application has a larger cleaning area compared to existing brush heads. This allows for faster cleaning speeds and improved cleaning efficiency when cleaning steel of the same area. Compared to existing cleaning brush heads, this design allows operators to complete rust removal and cleaning tasks more quickly and effortlessly.

[0031] The steel truss frame is mainly constructed using steel materials such as channel steel or angle steel. Channel steel or angle steel has the advantages of high structural strength, low cost, and easy availability.

[0032] In some embodiments, the driving component 30 refers to an angle grinder. The cleaning brush head provided in this application is installed on the angle grinder, and the high-speed rotation generated by the rotation of the angle grinder drives the cleaning brush head to rotate, thereby cleaning the steel. An angle grinder is a high-speed handheld power tool that can perform grinding, cutting, rust removal, and polishing operations through a rotating grinding wheel, cutting disc, and rust removal brush head. Using the cleaning brush head provided in this application installed on an angle grinder, rust removal and grinding can be completed, facilitating subsequent painting processes.

[0033] Existing cleaning brush heads are mostly bowl-shaped, with bristles arranged in a ring. During cleaning, the brushes primarily rely on the rim of the bowl to clean the steel. However, the rim has limited effectiveness in cleaning hard-to-reach areas, requiring repeated cleaning by the operator, which is time-consuming and labor-intensive. Furthermore, there is a possibility of repeated rusting after recoating with an anti-corrosion coating. The cleaning brush head of this application, however, provides excellent cleaning results in hard-to-reach areas, allowing operators to clean more efficiently and effectively.

[0034] The cleaning component 23 can be of various types. In some embodiments, the cleaning component 23 can adopt the existing manufacturing process of a bowl-shaped brush head, where multiple strands of steel wire are folded in half, and a galvanized iron wire or stainless steel wire is threaded through the middle as a "core rod," which is then twisted like a rope. The tightened root is inserted into the radial groove or central hole of the metal base, and then the core rod is flattened with hydraulic pliers to form a "T"-shaped tail end, which prevents both pulling and rotation. In some embodiments, the cleaning component 23 can also adopt a stamped riveting structure. A sufficient number of rivet holes are stamped on the base, and after the steel wire bundle passes through the holes, it is stamped once with a punch press to flatten the rivet feet, so that the steel wire bundle is mechanically locked in the holes.

[0035] Of course, the cleaning brush head provided in this application is only for channel steel and right angle steel 40. For other shapes of steel, other cleaning brush heads with suitable structures can be used. For example, for angle steel with an included angle of less than 90°, a triangular cleaning brush head can be used, and in order to facilitate the connection between the cleaning brush head and the angle grinder, the form of the connecting part 11 needs to be reasonably designed.

[0036] In certain situations, the cleaning brush head of this application can also be used to clean rust from bolts and other components. Of course, besides rust removal, the cleaning brush head can also be used to clean other contaminants such as grease.

[0037] Combination Figure 1As shown, the brush holder 10 includes a mounting plate 12 and an annular side plate 13 connected to each other. The annular side plate 13 surrounds the outer periphery of the mounting plate 12, and the mounting plate 12 and the annular side plate 13 together form a U-shaped frame structure. Both the mounting plate 12 and the annular side plate 13 are provided with cleaning components 23. A connecting part 11 is provided on the mounting plate 12. Using the above-described brush holder 10 structure, with the mounting plate 12 and the annular side plate 13 forming a U-shaped frame structure, and cleaning components 23 provided on both the mounting plate 12 and the annular side plate 13, it has the advantages of simple structure and easy processing.

[0038] In some embodiments, the mounting plate 12 has a circular plate structure, and the annular side plate 13 has a circular cylindrical structure. The brush holder 10 can be manufactured by separately processing the mounting plate 12 and the annular side plate 13 and then assembling them. Alternatively, it can be manufactured using a one-piece molding process. For example, the brush holder 10 can be processed using bending or stamping.

[0039] It should be noted that, in order to further enhance the cleaning effect, a cleaning component 23 is also provided at the junction of the mounting plate 12 and the annular side plate 13, and the cleaning component 23 extends toward the outside of the brush holder 10.

[0040] In some embodiments, the connection between the mounting plate 12 and the annular side plate 13 is rounded, in which case the mounting plate 12 and the annular side plate 13 can be integrally formed. Holes are pre-fabricated to avoid the cleaning component 23. Using the above manufacturing process avoids welding the mounting plate 12 and the annular side plate 13, simplifies the processing, and improves the structural strength of the brush holder 10.

[0041] Combination Figure 1 As shown, the mounting plate 12 includes a first support plate 121 and a first pressure plate 122 connected to each other. One end of the cleaning component 23 is clamped between the first support plate 121 and the first pressure plate 122, and the other end of the cleaning component 23 extends out of the first pressure plate 122. Using the mounting plate 12 described above, the cleaning component 23 is supported and fixed by the first support plate 121 and the first pressure plate 122, which has the advantages of simple structure and ease of processing.

[0042] Combination Figure 1 As shown, the annular side plate 13 includes a second support plate 131 and a second pressure plate 132 connected together. One end of the cleaning member 23 is clamped between the second support plate 131 and the second pressure plate 132, and the other end of the cleaning member 23 protrudes through the second pressure plate 132. Using the aforementioned annular side plate 13, and utilizing the second support plate 131 and the second pressure plate 132 to support and fix the cleaning member 23, has the advantages of simple structure and ease of processing.

[0043] The first support plate 121, the first pressure plate 122, the second support plate 131, and the second pressure plate 132 all have the same structure. Both are metal plates with a certain structural strength, used to fix the cleaning component 23.

[0044] It should be noted that the structure of the mounting plate 12 and the annular side plate 13 described above, by being configured as two connected support plates and pressure plates, makes the space between the support plates and pressure plates hollow, which can reduce the weight of the brush holder 10 and thus reduce the energy consumption of the angle grinder. In other embodiments, the mounting plate 12 and the annular side plate 13 can also be configured as solid plate structures, and the cleaning component 23 can be installed by designing mounting holes on the plate structure.

[0045] In some embodiments, the connecting portion 11 is a through hole that passes through the first support plate 121 and the first pressure plate 122. By passing the rotating shaft of the drive member 30 through the through hole, the cleaning brush head is fixed to the drive member 30, which facilitates the assembly and disassembly of the cleaning brush head.

[0046] It should be noted that the angle grinder and brush head are generally fastened together by a threaded connection. The angle grinder's shaft usually has external threads, and the brush head is clamped onto the shaft using a specific type of nut to secure the brush head.

[0047] Because the angle grinder and cleaning brush head are fixed by a rotating shaft passing through a through hole and secured by a nut and threaded connection, the cleaning component 23 cannot be arranged in the middle of the first support plate 121 and the first pressure plate 122 due to the through hole. Furthermore, since the rotating shaft needs to pass through the through hole, the edge of the through hole must also avoid the rotating shaft, making it impossible to install the cleaning component 23. The distance between the edge of the through hole and the cleaning component 23 needs to be determined based on the actual situation.

[0048] In some embodiments, the thicknesses of the first support plate 121, the second support plate 131, the first pressure plate 122, and the second pressure plate 132 are all greater than or equal to 0.5 mm and less than or equal to 5 mm. By using the above-mentioned thickness range, it is possible to ensure that the brush holder 10 has a large structural strength while ensuring that the thickness of the brush holder 10 is not too large and will not affect the installation of the cleaning component 23.

[0049] The thickness of the first support plate 121, the second support plate 131, the first pressure plate 122, and the second pressure plate 132 can all be 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, or any value greater than or equal to 0.5mm and less than or equal to 5mm.

[0050] In some embodiments, the first support plate 121 and the second support plate 131 have the same thickness, as do the first pressure plate 122 and the second pressure plate 132. In some embodiments, the thicknesses of the first support plate 121, the second support plate 131, the first pressure plate 122, and the second pressure plate 132 are all different. Of course, the thicknesses of the first support plate 121, the second support plate 131, the first pressure plate 122, and the second pressure plate 132 can also be the same. The specific thickness needs to be determined according to the actual situation.

[0051] Combination Figure 1 and Figure 2 As shown, the cleaning assembly 20 includes a plurality of first cleaning units 21, which are arranged radially at intervals along the mounting plate 12. Each first cleaning unit 21 includes a plurality of cleaning components 23 arranged circumferentially at intervals along the mounting plate 12. This design allows for the arrangement of a sufficient number of cleaning components 23 in the radial direction of the mounting plate 12, offering advantages such as simple structure and ease of processing.

[0052] In the first cleaning unit 21, the cleaning components 23 are arranged in a circular structure. The innermost cleaning unit surrounds the outer periphery of the through hole, and the remaining cleaning units are arranged sequentially along the radial direction of the mounting plate 12.

[0053] Combination Figure 1 and Figure 2 As shown, the cleaning assembly 20 includes multiple second cleaning units 22, which are spaced apart along the height direction of the annular side plate 13. Each second cleaning unit 22 includes multiple cleaning components 23 spaced apart along the circumference of the annular side plate 13. This design allows for the arrangement of a sufficient number of cleaning components 23 along the height direction of the annular side plate 13, offering advantages such as simple structure and ease of processing.

[0054] In this unit, the cleaning components 23 of the second cleaning unit 22 are arranged in a circular structure. Furthermore, the number of cleaning components 23 in the first cleaning unit 21 is the same as the number of cleaning components 23 in the second cleaning unit 22.

[0055] Combination Figure 1 and Figure 2 As shown, when the cleaning assembly 20 includes multiple first cleaning units 21, the number of cleaning components 23 in each of the multiple first cleaning units 21 is the same, and the cleaning components 23 corresponding to the multiple first cleaning units 21 are arranged linearly. This design allows the cleaning brush head to have a reasonable layout, facilitating its processing.

[0056] Combination Figure 1 and Figure 2As shown, when the cleaning assembly 20 includes multiple second cleaning units 22, the number of cleaning components 23 in each of the multiple second cleaning units 22 is the same, and the cleaning components 23 corresponding to the multiple second cleaning units 22 are arranged linearly. This design allows the cleaning brush head to have a reasonable layout, facilitating its processing.

[0057] It should be noted that since the number of cleaning elements 23 in each first cleaning unit 21 is the same in the direction away from the through hole, the distance between two adjacent cleaning elements 23 is greater the first cleaning unit 21 is further away from the through hole. At this time, the cleaning elements 23 can adopt a design with more bristles 231, so that the cleaning effect of the cleaning brush head is better.

[0058] Of course, in other embodiments, other arrangements can be used to increase the number of cleaning components 23. For example, the number of cleaning components 23 in the first cleaning unit 21 can be gradually increased in the direction away from the through hole. As long as a good cleaning effect can be achieved, it is acceptable.

[0059] In some embodiments, the cleaning component 23 includes a wire brush, the extension direction of which is perpendicular to the plane containing the outer wall of the brush holder 10. The wire brush design provides high structural strength, resulting in a better cleaning effect.

[0060] The wire brush includes multiple bristles 231, with the spacing between adjacent bristles 231 gradually increasing in the direction away from the brush holder 10. This design, through the arrangement of multiple bristles 231 and their spacing, allows each wire brush to have a larger cleaning area, while reducing the spacing between adjacent bristles to enhance the cleaning effect.

[0061] The bristles of the cleaning brush head are primarily made of high-carbon steel, supplemented by stainless steel and alloy steel. Different grades of material can be used for different application scenarios. To ensure a long service life for the cleaning brush head, the selected material should have high hardness, high wear resistance, fatigue resistance, and rust resistance.

[0062] In some embodiments, the brush holder 10 is made of metal. The use of metal provides high structural strength, resulting in a longer service life for the cleaning brush head.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
