Description

Technical Field

[0001] This invention specifically relates to a non-destructive descaling agent for tower crane wire ropes and a non-destructive descaling method thereof, belonging to the field of tower crane maintenance technology. Background Technology

[0002] Tower crane wire ropes accumulate a layer of oil during use. If not cleaned promptly, this oil will affect their service life and traction capacity. Oil alters the coefficient of friction, reducing traction and thus impacting the normal operation and safety of the tower crane. Therefore, tower crane wire ropes require regular maintenance, typically achieved by applying grease. The main reasons for using grease on tower crane wire ropes are: grease forms a lubricating film on the wire rope surface, reducing friction with pulleys, drums, and other components, thereby reducing wear and extending service life; grease also forms a protective layer, preventing corrosion caused by humid air and rain, and its adhesive properties prevent dust and dirt from adhering, reducing the risk of wear and corrosion. Furthermore, in the absence of dedicated wire rope lubricants, grease can be used as a temporary lubricant in emergencies.

[0003] However, using butter can produce sludge. During use, especially in high-temperature, humid, or dusty environments, the grease in butter gradually oxidizes and deteriorates, mixing with dust, impurities, and metal particles generated during equipment operation to form sludge. This sludge adheres to the surface of equipment, affecting lubrication and potentially causing equipment malfunction.

[0004] Therefore, in routine maintenance, not only should wire ropes be greased, but the grease on the surface of the wire rope should also be removed before greasing. However, in actual wire rope maintenance, the grease on the surface of the wire rope is usually not removed, and grease is directly applied to the surface of the wire rope, which will directly lead to the following drawbacks:

[0005] 1. The sludge prevents the newly applied grease from penetrating the inside of the wire rope, reducing its maintenance effect;

[0006] 2. The freshly applied butter mixes with the oil residue, affecting the butter's lubricating effect;

[0007] 3. Apply butter to the surface of the mud so that the butter can only adhere to the outer surface of the wire rope and is easier to remove. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, a non-destructive oil and sludge removal unit for tower crane wire ropes is provided to solve the above problems.

[0009] A non-destructive descaling unit for tower crane wire ropes includes a base support, a self-assembling rotating drum, and multiple self-adjusting steel brushes. The self-assembling rotating drum is slidably mounted on the base support, and multiple self-adjusting steel brushes are slidably mounted on the self-assembling rotating drum. Each self-adjusting steel brush includes a knob, a threaded rod, a slider, steel brush bristles, two positioning screws, and two side ears. One end of the knob has a threaded rod that passes through the slider and is threadedly connected to it. One end of the threaded rod has steel brush bristles. The slider is slidably mounted on the self-assembling rotating drum. A side ear is located on each side of the slider near the end of the knob, and a positioning screw passes through each side ear. Each positioning screw is threadedly connected to its corresponding side ear, and the tip of the positioning screw rests against the outer wall of the self-assembling rotating drum. When the steel brush bristles are in use, the threaded rod screws in, pushing the steel brush bristles inward along the radial direction of the self-assembling rotating drum. When the steel brush bristles are not in use, the threaded rod screws out, causing the steel brush bristles to move outward along the radial direction of the self-assembling rotating drum.

[0010] As a preferred embodiment: the self-assembling rotary drum includes two arc-shaped shells and four arc-shaped protruding flanges. Each arc-shaped shell has an arc-shaped protruding flange at both ends. The arc-shaped protruding flange is a semi-circular strip. The two arc-shaped shells are arranged side by side and opposite each other. When the two arc-shaped shells move relative to each other, the inner walls of the two arc-shaped shells form an inner through hole for the steel wire rope. Each arc-shaped protruding flange is detachably connected to the other arc-shaped protruding flange next to it to form an outer protruding ring. Each arc-shaped shell is machined with multiple arc-shaped grooves along its circumference. Each arc-shaped groove is provided with at least one self-adjusting steel brush. The slider in each self-adjusting steel brush slides back and forth along the length of the arc-shaped groove in which it is located. The tip of the positioning screw in each self-adjusting steel brush is attached to the outer wall of the arc-shaped shell in which it is located.

[0011] As a preferred embodiment: two convex rings are arranged side by side on the bottom support base, and each convex ring is slidably engaged with the end of the bottom support base. The bottom support base includes a connecting block, a top seat, an elastic washer, an elastic pad, a support plate, and two clamping screws. The top seat is provided at the upper end of the connecting block, and the two ends of the top seat are respectively machined with arc-shaped grooves that are slidably engaged with the convex rings. An elastic washer is provided on the inner wall of the connecting block, and an adjustment screw hole is machined on each side of the connecting block. A clamping screw is connected to each adjustment screw hole. Each clamping screw passes through the support plate and is detachably connected to its corresponding adjustment screw hole. An elastic pad is provided on the side of the support plate near the elastic washer, and the outer wall shape of the elastic pad is matched with the inner wall shape of the elastic washer.

[0012] As a preferred embodiment: one side of the connecting block is machined with multiple extrusion screw holes along its thickness direction. When the bottom support is in the vertical clamping state, the clamping screws are in the vertical use state, and each clamping screw passes through the support plate and connects to its corresponding adjustment screw hole. When the bottom support is in the horizontal clamping state, the clamping screws are in the horizontal use state, and each clamping screw passes through its nearest extrusion screw hole.

[0013] As a preferred option: each of the two ends of the arc-shaped convex flange is machined with bolt holes, and the bolts are inserted into the two bolt holes to form an outer convex ring body by the two arc-shaped convex flanges.

[0014] As a preferred option: the connecting block is replaced with a sleeve, the inner wall of which is machined with a strip groove along its thickness direction, the sleeve is fitted onto the shaft bracket, the shaft bracket is provided with a strip protrusion, and the strip protrusion is slidably disposed in the strip groove.

[0015] As a preferred embodiment: a support leg is provided at each end of the shaft bracket, and the two support legs face the same direction. A disc is provided at the lower end of each support leg, and multiple positioning holes are machined on the upper surface of the disc along its circumference. Each support leg includes an upper cylinder, a connecting bottom column, a telescopic column, and an elastic element. A disc is provided at the lower end of the connecting bottom column, and a telescopic column is provided at the upper end of the connecting bottom column. The telescopic column passes through the cavity of the upper cylinder, and an elastic element is provided in the cavity of the upper cylinder. One end of the elastic element contacts the upper surface of the telescopic column, and the other end of the elastic element contacts the inner wall of the cavity of the upper cylinder.

[0016] A non-destructive method for removing oil and sludge from tower crane wire ropes utilizes a single non-destructive oil and sludge removal unit. This unit is fixed to the iron frame structure below the tower crane wire rope. A self-assembling drum is split into two halves. One half of the self-assembling drum has its arc-shaped outer protrusion sliding edge installed within an arc-shaped groove, with the cross-section of the arc-shaped outer protrusion facing upwards. The wire rope is then arranged within the cavity of the self-assembling drum. The other half of the self-assembling drum is then bolted on to form a complete drum body. A knob is then rotated, causing a threaded rod to rotate. The threaded rod is threadedly connected to the slider, at which point the threaded rod moves towards the self-assembling... The self-adjusting steel brush moves within the rotating drum, completing the process of the threaded rod pushing the steel brush bristles to adhere to the wire rope. Using positioning screws, the position of each self-adjusting steel brush is adjusted one by one to ensure tight contact between the bristles and the outer wall of the wire rope, with the ends of the bristles in a bent state. This causes multiple self-adjusting steel brushes to form a spiral trajectory, thus creating a spiral motion trajectory within the self-joining rotating drum that matches the spiral line of the wire rope. The tower crane operator operates the wire rope at a uniform speed of 0.05–0.2 m / s for the wire rope release operation. As the wire rope moves, it passes over the steel brush bristles, which clean the oil and sludge along the spiral line of the wire rope.

[0017] The beneficial effects of this invention are as follows:

[0018] The non-destructive degreasing unit of this invention can be positioned as needed at the location of the tower crane wire rope. Through the cooperation of a bottom support, a self-assembling rotating drum, and multiple self-adjusting steel brushes, it achieves real-time cleaning of the oil sludge on the wire rope surface. The bottom support structure allows it to be installed on the tower crane near the output position of the wire rope, following its direction. The bottom support and the self-assembling rotating drum work together to allow the self-adjusting steel brushes to move along the spiral line of the wire rope during the cleaning process. By utilizing the extended state of the wire rope, it achieves a simultaneous and comprehensive cleaning and removal of the oil sludge. This improves the uniformity of cleaning across the circumference of the wire rope and reduces wear on the wire rope during cleaning, achieving a standardized and non-destructive cleaning process for residual oil stains. The non-destructive degreasing unit can be installed in various positions on the tower crane, clamping onto the crane as needed for oil sludge removal. The non-destructive degreasing method of this invention is simple, its placement is adjustable, and it effectively and systematically standardizes the degreasing process for wire ropes.

Detailed Implementation

[0031] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11This embodiment describes a non-destructive sludge removal unit comprising a base support 2, a self-assembling rotating drum 3, and multiple self-adjusting steel brushes 4. The self-assembling rotating drum 3 is slidably mounted on the base support 2, and multiple self-adjusting steel brushes 4 are slidably mounted on the self-assembling rotating drum 3. Each self-adjusting steel brush 4 includes a knob 4-1, a threaded rod 4-2, a slider 4-3, steel brush bristles 4-4, two positioning screws 4-5, and two side lugs 4-6. One end of the knob 4-1 has a threaded rod 4-2, which passes through the slider 4-3 and is threadedly connected to the slider 4-3. One end of the threaded rod 4-2 has steel brush bristles 4-4. The slider 4-1... 3. The slider 4-3 is mounted on the self-assembly rotating cylinder 3. A side lug 4-6 is provided on each side of the slider 4-3 near the end of the knob 4-1. A positioning screw 4-5 is provided on each side lug 4-6. Each positioning screw 4-5 is threadedly connected to its corresponding side lug 4-6. The tip of the positioning screw 4-5 is attached to the outer wall of the self-assembly rotating cylinder 3. When the steel brush bristles 4-4 are in use, the threaded rod 4-2 is screwed in to push the steel brush bristles 4-4 to move inward along the radial direction of the self-assembly rotating cylinder 3. When the steel brush bristles 4-4 are not in use, the threaded rod 4-2 is screwed out to drive the steel brush bristles 4-4 to move outward along the radial direction of the self-assembly rotating cylinder 3.

[0033] Rotate the knob 4-1, which drives the threaded rod 4-2 to rotate. The threaded rod 4-2 is threadedly connected to the slider 4-3. At this time, the threaded rod 4-2 moves into the self-assembling rotating drum 3, so that the threaded rod 4-2 pushes the steel brush bristles 4-4 to stick to the steel wire rope 5, thereby adjusting the cleaning force of the steel brush bristles 4-4 on the steel wire rope 5. When the threaded rod 4-2 drives the steel brush bristles 4-4 away from the steel wire rope 5, the actual number of steel brush bristles 4-4 used is controlled.

[0034] Loosen the positioning screw 4-5. At this time, the slider 4-3 can slide freely in the adjusting arc groove 3-1-1 to adjust the position of the steel brush bristles 4-4. By adjusting the position of each self-adjusting steel brush 4 one by one through the positioning screw 4-5, the multiple self-adjusting steel brushes 4 form a spiral trajectory, and then the multiple steel brush bristles 4-4 form a spiral trajectory in the self-splitting rotating drum 3 that is the same as the spiral line of the steel wire rope 5. When the steel wire rope 5 moves, the multiple steel brush bristles 4-4 will clean the oil sludge along the spiral line of the steel wire rope 5, improving the cleaning effect. At this time, the arc-shaped outer protrusion 3-2 will rotate in the bottom support 2. The rotation generated by the multiple steel brush bristles 4-4 moving along the spiral line of the steel wire rope 5 improves the smoothness of cleaning oil sludge.

[0035] After the steel brush bristles 4-4 have been used for a period of time, the contact end between the steel brush bristles 4-4 and the wire rope 5 will be bent. At this time, the threaded rod 4-2 can be rotated by the knob 4-1, thereby changing the direction of the end of the steel brush bristles 4-4, so that the tip of the steel brush bristles 4-4 can re-contact the surface of the wire rope 5, thus improving the utilization rate of the steel brush bristles 4-4.

[0036] This invention enables the installation of the wire rope 5 on the tower crane near the output position of the wire rope 5, according to the direction of the wire rope 5. The configuration position is within the range of the moving trajectory of the wire rope 5 on the tower crane, ensuring that the invention can be easily installed coaxially with the wire rope 5.

[0037] Specific Implementation Method Two: This implementation method further defines Specific Implementation Method One. The self-assembling rotary drum 3 includes two arc-shaped shells 3-1 and four arc-shaped outwardly protruding flanges 3-2. Each arc-shaped shell 3-1 has an arc-shaped outwardly protruding flange 3-2 at both ends. The arc-shaped outwardly protruding flanges 3-2 are semi-circular strips. The two arc-shaped shells 3-1 are arranged side by side and opposite to each other. When the two arc-shaped shells 3-1 move towards each other, the inner walls of the two arc-shaped shells 3-1 form an inner through hole 7 for the steel wire rope 5. Each arc-shaped convex flange 3-2 is detachably connected to another adjacent arc-shaped convex flange 3-2 to form an convex ring body 8. Each arc-shaped housing 3-1 has multiple arc-shaped grooves 3-1-1 machined along its circumference. Each arc-shaped groove 3-1-1 is provided with at least one self-adjusting steel brush 4. The slider 4-3 in each self-adjusting steel brush 4 slides back and forth along the length of the arc-shaped groove 3-1-1 in which it is located. The tip of the positioning screw 4-5 in each self-adjusting steel brush 4 abuts against the outer wall of the arc-shaped housing 3-1 in which it is located.

[0038] An arc-shaped shell 3-1 and two arc-shaped protruding edges 3-2 form half of the protruding ring 8, which can realize the quick installation and disassembly of the protruding ring 8. It helps to open the protruding ring 8 to clean the oil sludge scattered in the inner through hole 7, and also makes it easier to clean the oil sludge adhering to the steel brush bristles 4-4. During the cleaning process, some oil sludge will also fall off from the arc-shaped groove 3-1-1.

[0039] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. Two convex ring bodies 8 are arranged side by side on the bottom support base 2. Each convex ring body 8 is slidably engaged with the end of the bottom support base 2. The bottom support base 2 includes a connecting block 2-1, a top seat 2-2, an elastic washer 2-3, an elastic pad 2-4, a support plate 2-5, and two clamping screws 2-6. The top seat 2-2 is provided at the upper end of the connecting block 2-1. The two ends of the top seat 2-2 are respectively machined with arc-shaped grooves 2 that are slidably engaged with the convex ring bodies 8. -2-1, An elastic washer 2-3 is provided on the inner wall of the connecting block 2-1. An adjustment screw hole 2-1-2 is machined on each side of the connecting block 2-1. A clamping screw 2-6 is connected to each adjustment screw hole 2-1-2. Each clamping screw 2-6 passes through the support plate 2-5 and is detachably connected to its corresponding adjustment screw hole 2-1-2. An elastic pad 2-4 is provided on the side of the support plate 2-5 near the elastic washer 2-3. The outer wall shape of the elastic pad 2-4 is matched with the inner wall shape of the elastic washer 2-3.

[0040] Place the connecting block 2-1 on the tower crane's rod, so that the elastic pad 2-3 contacts it. At this time, thread the clamping screw 2-6 into the adjusting screw hole 2-1-2, so that the support plate 2-5 moves towards the elastic pad 2-3, thereby causing the elastic pad 2-4 to press against the tower crane's rod, thus clamping and fixing the non-destructive oil sludge unit onto the tower crane's rod.

[0041] Specific Implementation Method Four: This implementation method further defines Specific Implementation Method One, Two, or Three. One side of the connecting block 2-1 is machined with multiple extrusion screw holes 2-1-1 along its thickness direction. When the bottom support 2 is in the vertical clamping state, the clamping screws 2-6 are in the vertical use state, and each clamping screw 2-6 passes through the support plate 2-5 and is connected to its corresponding adjustment screw hole 2-1-2. When the bottom support 2 is in the horizontal clamping state, the clamping screws 2-6 are in the horizontal use state, and each clamping screw 2-6 passes through its nearest extrusion screw hole 2-1-1.

[0042] When the installation location is a plate structure, after removing the elastic pad 2-4 and the support plate 2-5, install the connecting block 2-1 on the upper end of the plate. The clamping screw 2-6 passes through the extrusion screw hole 2-1-1, and the clamping screw 2-6 is threaded into the extrusion screw hole 2-1-1, causing the end of the clamping screw 2-6 to press against the plate, achieving non-destructive clamping and fixing of the entire oil sludge unit. Figure 2As shown, there are multiple extrusion screw holes 2-1-1. When there are four extrusion screw holes 2-1-1, the four extrusion screw holes 2-1-1 are arranged in a matrix, that is, the four extrusion screw holes 2-1-1 are respectively arranged at the four corners of the square matrix. The two clamping screws 2-6 are installed on the two extrusion screw holes 2-1-1 that are diagonally related. This arrangement can help improve the stability of the two clamping screws 2-6 in positioning the bottom support 2, and can also increase the number of the two clamping screws 2-6 to further increase the clamping stability.

[0043] Specific Implementation Method 5: This implementation method further defines Specific Implementation Methods 1, 2, 3, or 4. Each arc-shaped convex retaining edge 3-2 has bolt holes 3-2-1 machined at both ends. Bolts 9 are inserted into the two bolt holes 3-2-1 to form an outer convex ring 8 around the two arc-shaped convex retaining edges 3-2. The two arc-shaped convex retaining edges 3-2 are connected by bolts 9, which can meet the requirements for quick assembly and disassembly of the arc-shaped convex retaining edges 3-2.

[0044] The working principle of this implementation method is as follows:

[0045] The non-destructive sludge removal unit is fixed to the iron frame structure below the tower crane wire rope 5. The self-assembling drum 3 is split into two halves. One half of the self-assembling drum 3 is slidably installed in the arc-shaped groove 2-2-1 along the arc-shaped outer protrusion 3-2, with the cross-section of the arc-shaped outer protrusion 3-2 facing upwards. Then, the wire rope 5 is placed in the cavity of the self-assembling drum 3. The other half of the self-assembling drum 3 is then installed with bolts 9 to form a complete cylindrical shape. Then, the knob 4-1 is rotated, which drives the threaded rod 4-2 to rotate. The threaded rod 4-2 is threadedly connected to the slider 4-3. At this time, the threaded rod 4-2 moves towards the self-assembling... The rotating drum 3 moves, causing the threaded rod 4-2 to push the steel brush bristles 4-4 against the wire rope 5. Using the positioning screws 4-5, the position of each self-adjusting steel brush 4 is adjusted one by one, causing multiple self-adjusting steel brushes 4 to form a spiral trajectory. This, in turn, causes multiple steel brush bristles 4-4 to form a spiral trajectory within the self-joining rotating drum 3 that is identical to the spiral line of the wire rope 5. When the tower crane operator operates the wire rope 5 to lay the line, the wire rope 5 passes over the steel brush bristles 4-4 during its movement. The multiple steel brush bristles 4-4 clean the oil and sludge along the spiral line of the wire rope 5, improving the cleaning effect and ultimately achieving the purpose of removing the oil and sludge from the wire rope 5.

[0046] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four or Five. The connecting block 2-1 is replaced with a sleeve 21. The inner wall of the sleeve 21 is machined with a strip groove 21-1 along its thickness direction. The sleeve 21 is fitted onto the shaft bracket 1. The shaft bracket 1 is provided with a strip protrusion 1-1. The strip protrusion 1-1 is slidably disposed in the strip groove 21-1.

[0047] The working principle of the shaft bracket 1 in this embodiment, in conjunction with the non-destructive sludge removal unit:

[0048] The shaft frame 1 is installed in front of the drum of the tower crane wire rope 5. As the wire rope 5 is unloaded or retracted, and as the wire rope 5 undergoes lateral displacement, the sleeve 21 can also move laterally on the shaft frame 1.

[0049] Specific Implementation Method Seven: This implementation method further defines Specific Implementation Methods One, Two, Three, Four, Five, or Six. A support leg 1-2 is provided at each end of the shaft bracket 1, with both support legs 1-2 facing the same direction. A disc body 1-3 is provided at the lower end of each support leg 1-2, and multiple positioning holes 1-3-1 are machined along the circumference of the upper surface of the disc body 1-3. Each support leg 1-2 includes an upper cylinder 1-2-1, a connecting bottom column 1-2-2, and a telescopic column 1-2-3. The lower end of the connecting base column 1-2-2 is provided with a disc body 1-3 and the upper end of the connecting base column 1-2-2 is provided with a telescopic column 1-2-3. The telescopic column 1-2-3 passes through the cavity of the upper cylinder 1-2-1. The elastic element 1-2-4 is provided in the cavity of the upper cylinder 1-2-1. One end of the elastic element 1-2-4 is in contact with the upper end face of the telescopic column 1-2-3, and the other end of the elastic element 1-2-4 is in contact with the inner wall of the cavity of the upper cylinder 1-2-1.

[0050] During the wire rope 5 release or reeling operations, the vertical position of the wire rope 5 will change accordingly, rising or falling. When the wire rope 5 descends, it applies pressure to the shaft frame 1. At this time, the upper cylinder 1-2-1 squeezes the elastic element 1-2-4, thereby shortening the support leg 1-2, achieving the purpose of lowering the vertical position of the self-splitting drum 3, and thus reducing the friction between the wire rope 5 and the drum 3.

[0051] Specific implementation method eight: Combination Figures 1 to 11This embodiment describes a non-destructive sludge removal method specifically implemented using a single non-destructive sludge removal unit. The unit is fixed to the iron frame structure below the tower crane wire rope 5. The self-assembly drum 3 is split into two halves. One half of the self-assembly drum 3 is slidably installed in the arc-shaped groove 2-2-1 with the arc-shaped protrusion along 3-2 facing upwards. The wire rope 5 is then placed inside the cavity of the self-assembly drum 3. The other half of the self-assembly drum 3 is then installed using bolts 9 to form a complete drum. The knob 4-1 is then rotated, causing the threaded rod 4-2 to rotate. The threaded rod 4-2 is threadedly connected to the slider 4-3. The threaded rod 4-2 moves into the self-assembling drum 3, completing the process of the threaded rod 4-2 pushing the steel brush bristles 4-4 to adhere to the wire rope 5. Using the positioning screws 4-5, the position of each self-adjusting steel brush 4 is adjusted one by one to ensure that the steel brush bristles 4-4 are tightly attached to the outer wall of the wire rope 5, with the ends of the steel brush bristles 4-4 in a bent state. This causes multiple self-adjusting steel brushes 4-4 to form a spiral trajectory, thus creating a spiral motion trajectory within the self-assembling drum 3 that is identical to the spiral line of the wire rope 5. The tower crane operator operates the wire rope 5 at a uniform speed of 0.05–0.2 m / s to lay the wire. As the wire rope 5 moves, it passes over the steel brush bristles 4-4, and the multiple steel brush bristles 4-4 clean the sludge along the spiral line of the wire rope 5.

[0052] The non-destructive sludge removal unit in this embodiment includes a bottom support 2, a self-assembling rotating drum 3, and multiple self-adjusting steel brushes 4. The self-assembling rotating drum 3 is slidably mounted on the bottom support 2, and multiple self-adjusting steel brushes 4 are slidably mounted on the self-assembling rotating drum 3. Each self-adjusting steel brush 4 includes a knob 4-1, a threaded rod 4-2, a slider 4-3, steel brush bristles 4-4, two positioning screws 4-5, and two side lugs 4-6. One end of the knob 4-1 is provided with a threaded rod 4-2, which passes through the slider 4-3 and is threadedly connected to the slider 4-3. One end of the threaded rod 4-2 is provided with steel brush bristles 4-4. The slider 4-3 is slidably mounted on the bottom support 2. The slider 4-3, placed on the self-assembling rotating drum 3, has a side lug 4-6 on each side near the end of the knob 4-1. Each side lug 4-6 has a corresponding positioning screw 4-5 threaded through it. Each positioning screw 4-5 is threadedly connected to its corresponding side lug 4-6, with the tip of the positioning screw 4-5 resting against the outer wall of the self-assembling rotating drum 3. When the steel brush bristles 4-4 are in use, the threaded rod 4-2 screws in, pushing the steel brush bristles 4-4 inward along the radial direction of the self-assembling rotating drum 3. When the steel brush bristles 4-4 are not in use, the threaded rod 4-2 screws out, causing the steel brush bristles 4-4 to move outward along the radial direction of the self-assembling rotating drum 3.
