Description

Technical Field

[0001] The invention relates to the technical field of section steel surface treatment, in particular to section steel surface cleaning equipment. Background Art

[0002] Steel sections are a type of steel with a specific cross-section shape, such as I-beams and H-beams. Steel sections are an important material for building structures. They can act as a skeleton to bear most of the load, improving the overall strength and seismic resistance of the building. Currently, I-beams are often used as pillars in buildings. To prevent I-beams from rusting, a layer of anti-rust paint is usually applied to the surface of the I-beams. Over time, the original paint on the surface of the I-beams will crack and peel, exposing the surface of the I-beams directly to the air, causing the I-beams to rust. At this time, a layer of anti-rust paint needs to be applied to the surface of the I-beams. Before repainting, it is necessary to use steel surface cleaning equipment to remove the original paint on the surface of the I-beams.

[0003] Steel section surface cleaning equipment is a device that uses high-pressure water flow to clean the surface of steel sections. Steel section surface cleaning equipment is mainly used to remove rust and paint on the surface of steel sections. Steel section surface cleaning equipment generally includes a nozzle and a drive device. The nozzle can spray high-pressure water flow, and the drive device can drive the nozzle to move in the vertical direction and horizontally, so that the nozzle can remove the paint on the surface of the I-beam along a predetermined path. In the prior art, after the paint on the surface of the I-beam web is removed, the operator needs to adjust the overall direction of the steel section surface cleaning equipment so that the nozzle is facing the corner between the I-beam web and the wing plate. Only then can the nozzle flush the paint on the corner between the I-beam web and the wing plate. The operator needs to spend a lot of time adjusting the overall direction of the steel section surface cleaning equipment, which increases the downtime of the steel section surface cleaning equipment, which is not conducive to improving the cleaning efficiency of the steel section surface cleaning equipment. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides a section steel surface cleaning device, which is conducive to improving the cleaning efficiency of the section steel surface cleaning device.

[0005] According to an embodiment of the present invention, the surface cleaning equipment of the steel section includes a base; a cleaning device, the cleaning device including a mounting block, a swing block and a nozzle, the swing block is hinged on the mounting block, the nozzle is arranged on the swing block, and the nozzle is used to spray water; a driving device, the driving device is arranged on the base, the output end of the driving device is connected to the mounting block, the driving device is used to drive the mounting block to move in the up and down directions and the horizontal direction, so that the water flow sprayed from the nozzle can wash off the paint on the surface of the I-beam; the swing device, the swing device is arranged on the mounting block, and the swing device is used to drive the swing block to swing left or right, so that the nozzle can be directed to the left corner or right corner between the web and the wing of the I-beam.

[0006] It has at least the following beneficial effects:

[0007] To clean the I-beam web, the operator moves the entire steel cleaning machine so that the nozzle extends into the area between the web and the two flanges, facing the web. The nozzle then begins spraying water. A drive mechanism moves the mounting block vertically and horizontally, allowing the nozzle to follow a pre-set path. This allows the water jet from the nozzle to wash away paint from the I-beam web. Once the I-beam web is cleaned, the machine remains operational. The swing mechanism swings the swing block to the left, directing the nozzle toward the left corner between the I-beam web and flanges. The drive mechanism then raises the mounting block and then slowly lowers it, allowing the water jet from the nozzle to wash away paint from the left corner between the I-beam web and flanges. Once the paint on the left corner is cleaned, the machine remains operational. The swing mechanism swings the swing block to the right, directing the nozzle toward the right corner between the I-beam web and flanges. The drive unit then first raises the mounting block and then slowly lowers it, allowing the water jet from the nozzle to wash away the paint on the right corner between the I-beam web and flange. The swing mechanism in this section steel surface cleaning device can change the direction of the nozzle, allowing it to be directed toward either the left or right corner between the I-beam web and flange.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] refer to Figures 1 to 5 The steel section surface cleaning device according to an embodiment of the present invention includes a base 100, a cleaning device 200, a driving device 400 and a swinging device 300.

[0036] The cleaning device 200 includes a mounting block 230, a swing block 220, and a nozzle 210. The swing block 220 is hingedly connected to the mounting block 230. The nozzle 210 is mounted on the swing block 220 and is used to spray water. A driving device 400 is mounted on the base 100. The output end of the driving device 400 is connected to the mounting block 230. The driving device 400 is used to drive the mounting block 230 to move vertically and horizontally so that the water sprayed from the nozzle 210 can wash away the paint on the surface of the I-beam. The swing device 300 is mounted on the mounting block 230 and is used to drive the swing block 220 to swing left or right so that the nozzle 210 is directed toward the left corner or right corner between the web and flange of the I-beam.

[0037] It should be explained that the reference Figure 6An I-beam is a long steel bar with an I-shaped cross-section. It consists of two parallel left and right flanges and a central web. The corner between the left flange and the web is the left corner, and the corner between the right flange and the web is the right corner. In the embodiments of the present invention, the horizontal direction refers to the left-right direction and the front-back direction.

[0038] In the prior art, the steel surface cleaning equipment can only flush the paint off one surface of the I-beam at a time. For example, after the steel surface cleaning equipment flushes the paint off the surface of the left wing of the I-beam, the operator needs to move the steel surface cleaning equipment to the right wing of the I-beam. Only then can the steel surface cleaning equipment clean the paint off the surface of the right wing of the I-beam. The driving device 400 can drive the nozzle 210 to move along a predetermined path, so that the nozzle 210 can gradually flush the paint off the surface of the I-beam. When it is necessary to clean the surface of the web of the I-beam, the operator needs to move the entire steel surface cleaning equipment so that the nozzle 210 extends into the area between the web and the two wings. Then the driving device 400 drives the nozzle 210 to move from top to bottom and back and forth left and right, so that the water flow sprayed from the nozzle 210 can flush the paint off the surface of the web. On the one hand, to ensure effective cleaning, the nozzle 210 needs to be facing the active surface, that is, the nozzle 210 needs to be facing the surface to be cleaned on the I-beam. On the other hand, the paint at the corners is located at the intersection of two planes (the wing and the web), making the paint at the corners more adherent and less likely to fall off. As a result, the nozzle 210 cannot effectively remove the paint at the corners during the process of cleaning the paint on the web surface, so the paint on the corners needs to be cleaned specifically later.

[0039] After the paint skin on the web surface is cleaned, the operator needs to stop the steel surface cleaning equipment and adjust the overall direction of the steel surface cleaning equipment so that the overall direction of the steel surface cleaning equipment is biased to the left, thereby allowing the nozzle 210 to be directed toward the corner between the left wing plate and the web. After the nozzle 210 has cleaned the paint skin on the corner between the left wing plate and the web, the operator needs to stop the steel surface cleaning equipment and adjust the overall direction of the steel surface cleaning equipment so that the overall direction of the steel surface cleaning equipment is biased to the right, thereby allowing the nozzle 210 to be directed toward the corner between the right wing plate and the web. It can be seen that adjusting the overall direction of the steel surface cleaning equipment requires a lot of time, resulting in an increase in the downtime of the steel surface cleaning equipment, which is not conducive to improving the cleaning efficiency of the steel surface cleaning equipment.

[0040] The drive device 400 is disposed on the base 100, and the output end of the drive device 400 is connected to the cleaning device 200. The cleaning device 200 includes a mounting block 230, a swing block 220, and a nozzle 210. The output end of the drive device 400 is connected to the mounting block 230. The swing block 220 is hingedly connected to the mounting block 230, and the nozzle 210 is disposed on the swing block 220, allowing the swing block 220 and the nozzle 210 to swing relative to the mounting block 230. In this embodiment of the present invention, the cleaning device 200 is a high-pressure water jet cleaning device 200. The water jetted by the nozzle 210 is a high-pressure and high-speed water flow, which enables the water flow to completely remove paint and rust from the surface of the profile. The drive device 400 is capable of driving the mounting block 230 to move vertically and horizontally, allowing the mounting block 230, the swing block 220, and the nozzle 210 to move along a predetermined path, so that the nozzle 210 can completely remove paint from the surface of the steel profile. The swing device 300 is set on the mounting block 230. The swing device 300 can drive the swing block 220 to swing left or right, that is, the swing device 300 can drive the nozzle 210 to swing left or right, thereby enabling the nozzle 210 to face the left corner or right corner between the I-beam web and the wing plate.

[0041] As one embodiment of the present invention, the swinging device 300 includes a first waterproof cylinder and a second waterproof cylinder. The cylinder bodies of the first and second waterproof cylinders are both mounted on the mounting block 230, with the cylinder bodies of the first and second waterproof cylinders being located on the left and right sides of the mounting block 230, respectively. The piston rod of the first waterproof cylinder is in transmission connection with the left side of the swinging block 220, while the piston rod of the second waterproof cylinder is in transmission connection with the right side of the swinging block 220. It is understood that when it is necessary to clean the paint film on the left corner between the web and wing of the I-beam, the piston rod of the first waterproof cylinder retracts, while the piston rod of the second waterproof cylinder extends. The piston rod of the second waterproof cylinder can push the swinging block 220 to swing leftward, thereby causing the spray head 210 to swing leftward and toward the left corner between the web and wing of the I-beam. When it is necessary to clean the paint on the right corner between the I-beam web and the wing plate, the piston rod of the second waterproof cylinder retracts and the piston rod of the first waterproof cylinder extends. The piston rod of the first waterproof cylinder can push the swing block 220 to swing to the right, so that the nozzle 210 can swing to the right and toward the right corner between the I-beam web and the wing plate.

[0042] It will be appreciated that when the surface of the I-beam web needs to be cleaned, the operator can move the entire steel surface cleaning apparatus so that the nozzle 210 extends into the area between the web and the two wing panels, facing the web. The nozzle 210 then begins spraying water, and the drive unit 400 drives the mounting block 230 to move vertically and horizontally, allowing the nozzle 210 to move along a predetermined path. This allows the water jet from the nozzle 210 to wash away the paint on the surface of the I-beam web. After the surface of the I-beam web is cleaned, the apparatus does not need to be shut down. The swing unit 300 drives the swing block 220 to swing leftward, directing the nozzle 210 toward the left corner between the I-beam web and the wing panels. The drive unit 400 then first raises the mounting block 230 and then slowly lowers it, allowing the water jet from the nozzle 210 to wash away the paint on the left corner between the I-beam web and the wing panels. After the paint coating on the left corner is cleaned, the section steel surface cleaning device does not need to be shut down. The swinging device 300 can drive the swing block 220 to swing rightward, so that the nozzle 210 is directed toward the right corner between the I-beam web and the wing plate. Then, the driving device 400 first causes the mounting block 230 to rise and then drives the mounting block 230 to slowly descend, so that the water flow ejected from the nozzle 210 can wash away the paint coating on the right corner between the I-beam web and the wing plate. The swinging device 300 in the section steel surface cleaning device can change the direction of the nozzle 210 so that the nozzle 210 can be directed toward the left corner or the right corner between the I-beam web and the wing plate, eliminating the need for the operator to shut down the section steel surface cleaning device and adjust the overall direction, thereby shortening the downtime of the section steel surface cleaning device and thereby improving the cleaning efficiency of the section steel surface cleaning device.

[0043] In the embodiment of the present invention, the steel surface cleaning device can not only remove the paint on the steel surface, but also remove rust and impurities on the steel surface. On the other hand, the steel surface cleaning device of the embodiment of the present invention can also be used to clean the corners of H-beams, which will not be further described here.

[0044] refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 7The swing device 300 includes a transmission assembly 330, a first push rod 310, a second push rod 320, a first spring member 311 and a second spring member 321. The mounting block 230 is provided with a first guide hole and a second guide hole. The first push rod 310 and the second push rod 320 are respectively inserted into the first guide hole and the second guide hole. The first spring member 311 and the second spring member 321 are respectively sleeved on the first push rod 310 and the second push rod 320. The two ends of the first spring member 311 are respectively connected to the first push rod 310 and the mounting block 230. The first spring member 311 is used to drive one end of the first push rod 310 to always keep against the left side of the swing block 220. The two ends of the second spring member 321 are respectively connected to the second push rod 320 and the mounting block 2 30 is connected, the second spring member 321 is used to drive one end of the second push rod 320 to always keep against the right side of the swing block 220, the transmission assembly 330 is arranged on the mounting block 230, and the transmission assembly 330 is transmission-connected with the other end of the first push rod 310 and the second push rod 320, and the driving device 400 can drive the transmission assembly 330 to press against the left wing plate of the I-beam, so that the transmission assembly 330 drives the second push rod 320 to push the right end of the swing block 220 and make the swing block 220 swing to the left, and the driving device 400 can drive the transmission assembly 330 to press against the right wing plate of the I-beam, so that the transmission assembly 330 drives the first push rod 310 to push the left end of the swing block 220 and make the swing block 220 swing to the right. The transmission assembly 330 includes a rack 331, a gear 332 and a swing arm 333. The rack 331 is parallel to the left and right directions. A third guide hole is provided on the mounting block 230. The rack 331 can be slidably inserted into the third guide hole along the left and right directions. The gear 332 is meshed with the rack 331 and can be rotatably connected to the mounting block 230. The middle part of the swing arm 333 is connected to the gear 332. The left and right ends of the swing arm 333 are respectively connected to the first push rod 310 and the second push rod The other end of 320 is abutted against the left wing plate of the I-beam, and the driving device 400 can drive the left end of the rack 331 to abut against the left wing plate of the I-beam, so that the rack 331 moves to the right relative to the mounting block 230, and the right end of the swing arm 333 pushes the second push rod 320. The driving device 400 can drive the right end of the rack 331 to abut against the right wing plate of the I-beam, so that the rack 331 moves to the left relative to the mounting block 230, and the left end of the swing arm 333 pushes the first push rod 310.

[0045] It is understood that after the surface cleaning of the I-beam web is completed, the steel surface cleaning equipment does not need to be shut down. The drive device 400 drives the mounting block 230 to rise, allowing the nozzle 210 to rise to the desired position. The drive device 400 then drives the mounting block 230 to move leftward, causing the left end of the rack 331 to begin to abut against the left wing of the I-beam. The drive device 400 continues to drive the mounting block 230 to move leftward. At this time, the rack 331 moves rightward relative to the mounting block 230. Since the rack 331 is engaged with the gear 332, and the gear 332 is connected to the middle part of the swing arm 333, the rack 331 can drive the gear 332 to rotate, and the rotating gear 332 can drive the swing arm 333 to rotate. As the swing arm 333 begins to rotate, its right end pushes against the second push rod 320, causing it to extend and push against the right side of the swing block 220. This causes the second spring member 321 to stretch, the first spring member 311 to compress, and the first push rod 310 to retract, causing the swing block 220 and the spray head 210 on it to begin to swing leftward. When the swing block 220 has swung to an angle that positions the spray head 210 toward the left corner, the drive unit 400 stops driving the mounting block 230 leftward, ensuring that the left end of the rack 331 remains in contact with the left wing of the I-beam. The drive unit 400 then drives the mounting block 230 downward, allowing the water jet from the spray head 210 to wash away the paint on the left corner.

[0046] After the paint film on the corner between the I-beam web and the left wing is cleaned, the steel surface cleaning equipment does not need to be shut down. The drive unit 400 drives the mounting block 230 to the right. At this time, the left end of the rack 331 disengages from the left wing, the first spring member 311 begins to extend, and the second spring member 321 begins to compress, causing the swing block 220 and the spray head 210 on it to swing to the right. Under the action of the first and second spring members 311 and 321, the other end of the second push rod 320 pushes against the right end of the swing arm 333, causing the swing arm 333 and the gear 332 to rotate. The rotating gear 332 drives the rack 331 to move leftward and reset, and the swing block 220 and the spray head 210 on it also swing rightward and return to the normal position. After the spray head 210 returns to the normal position, the drive unit 400 drives the mounting block 230 to rise, allowing the spray head 210 to rise to the desired position. The drive unit 400 then drives the mounting block 230 to the right, causing the right end of the rack 331 to come into contact with the right wing of the I-beam. The drive unit 400 continues to drive the mounting block 230 to the right, causing the rack 331 to move leftward relative to the mounting block 230, allowing the rack 331 to rotate the gear 332 and the swing arm 333. As the swing arm 333 begins to rotate, the left end of the swing arm 333 pushes the first push rod 310 outward, causing the first push rod 310 to begin to extend and push the left side of the swing block 220. At this time, the first spring member 311 begins to stretch, the second spring member 321 begins to compress, and the second push rod 320 begins to retract, causing the swing block 220 and the nozzle 210 on it to begin to swing to the right. When the swing block 220 has swung to an angle that allows the nozzle 210 to face the right corner, the drive unit 400 stops driving the mounting block 230 to continue moving rightward, allowing the right end of the rack 331 to remain in contact with the right wing of the I-beam. The drive unit 400 then drives the mounting block 230 downward, allowing the water jet from the nozzle 210 to wash away the paint on the right corner. After the paint on the right corner is cleaned, the drive unit 400 drives the mounting block 230 to move leftward, disengaging the right end of the rack 331 from contact with the right wing. At this point, the swing block 220 and the nozzle 210 mounted on it can swing back to the left. The specific process will not be further described.

[0047] refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 7The transmission assembly 330 also includes a third spring member 334 and a fourth spring member 335, which are respectively mounted on the left and right ends of the rack 331. The ends of the third spring member 334 are connected to the left end of the rack 331 and the mounting block 230, respectively. The third spring member 334 is used to drive the rack 331 to the left. The ends of the fourth spring member 335 are connected to the right end of the rack 331 and the mounting block 230, respectively. The fourth spring member 335 is used to drive the rack 331 to the right. It can be understood that the left end of the rack 331 abuts the left wing plate, and when the rack 331 moves rightward relative to the mounting block 230, the third spring member 334 is compressed and the fourth spring member 335 is stretched. Under the action of the third and fourth spring members 334, 335, the left end of the rack 331 is able to maintain contact with the left wing of the I-beam, ensuring that the spray head 210 does not swing during the process of cleaning the paint on the left corner, allowing the spray head 210 to remain oriented toward the left corner. After the paint on the left corner is cleaned, the drive device 400 drives the mounting block 230 to move rightward, causing the left end of the rack 331 to disengage from the left wing. At this time, the third spring member 334 extends and the fourth spring member 335 retracts. Under the action of the third and fourth spring members 334, 335, the rack 331 can quickly move to the left, allowing the swing block 220 and the spray head 210 on the swing block 220 to quickly swing back to the right. The right end of the rack 331 is against the right wing. As the rack 331 moves leftward relative to the mounting block 230, the third spring member 334 stretches and contracts, while the fourth spring member 335 compresses. Under the action of the third and fourth spring members 334, 335, the right end of the rack 331 can always maintain contact with the right wing of the I-beam, ensuring that the nozzle 210 does not swing during the process of cleaning the paint on the right corner, so that the nozzle 210 can always be oriented toward the right corner. After the paint on the right corner is cleaned, the drive device 400 drives the mounting block 230 to move leftward, causing the right end of the rack 331 to disengage from the right wing. At this time, the third spring member 334 retracts and the fourth spring member 335 extends. Under the action of the third and fourth spring members 334, 335, the rack 331 can quickly move to the right, allowing the swing block 220 and the nozzle 210 on the swing block 220 to quickly swing back to the left.

[0048] In this embodiment of the present invention, the first spring member 311, the second spring member 321, the third spring member 334, and the fourth spring member 335 can all be compression springs. The first spring member 311 and the second spring member 321 have identical specifications, and the first and second push rods 310 and 320 also have identical specifications. The first and second spring members 311 and 321 are capable of respectively driving one end of the first and second push rods 310 and 320 to constantly press against the swing block 220, so that when the swing arm 333 is not rotating, the length of the first push rod 310 extending from the first guide hole is the same as the length of the second push rod 320 extending from the second guide hole, thereby returning the swing block 220 and the spray head 210 to their original position. Similarly, the third spring member 334 and the fourth spring member 335 have identical specifications. When the rack 331 is not subjected to external force, the length of the left end of the rack 331 extending from the third guide hole is the same as the length of the right end of the rack 331 extending from the third guide hole, thereby returning the swing block 220 and the spray head 210 to their original position. It needs to be explained that in the process of the nozzle 210 cleaning the paint on the corner from top to bottom, under the action of the driving device 400, the third spring member 334 and the fourth spring member 335, the left end or the right end of the rack 331 can always be kept in contact with the left wing plate or the right wing plate, thereby avoiding the swing block 220 and the nozzle 210 from swinging in the process of the nozzle 210 cleaning the corner, so that the nozzle 210 can smoothly clean the paint on the corner.

[0049] In an embodiment of the present invention, the upper and lower sides of the swing block 220 are hinged to the mounting block 230. Specifically, the steel section surface cleaning device further includes a fastener. The mounting block 230 is provided with a stud on its upper side. A hinge hole is formed on its upper side, and the stud is inserted into the hinge hole. The stud acts as a hinge axis, allowing the swing block 220 to swing about the axis of the stud. The fastener is threadedly connected to the stud and can rest against the swing block 220, securing the swing block 220 to the mounting block 230. It is understood that the fastener can be a nut. When cleaning the corners of the I-beam is not necessary, the operator can tighten the nut so that it presses against the swing block 220, securing the swing block 220 to the mounting block 230 and preventing the nozzle 210 from swinging during the cleaning process. As one embodiment of the present invention, the fastener is provided with a grip, which allows the operator to rotate the nut, making it easier to tighten the fastener.

[0050] refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 7The swing mechanism 300 further includes a first roller 312 and a second roller 322. The first roller 312 is rotatably connected to one end of the first push rod 310, and the first push rod 310 abuts against the swing block 220 via the first roller 312. The second roller 322 is rotatably connected to one end of the second push rod 320, and the second push rod 320 abuts against the swing block 220 via the second roller 322. It is understood that the first push rod 310 abuts against the swing block 220 via the first roller 312. When the first push rod 310 pushes the left side of the swing block 220, the first roller 312 rotates, thereby reducing the friction between the first push rod 310 and the swing block 220. The second push rod 320 abuts against the swing block 220 via the second roller 322. When the second push rod 320 pushes the right side of the swing block 220, the second roller 322 rotates, thereby reducing the friction between the second push rod 320 and the swing block 220.

[0051] refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 7 The transmission assembly 330 further includes a first universal ball 336 and a second universal ball 337, which are respectively disposed on the left and right ends of the rack 331. The left end of the rack 331 abuts against the left wing of the I-beam via the first universal ball 336, while the right end of the rack 331 abuts against the right wing of the I-beam via the second universal ball 337. It is understood that during the process of the spray head 210 cleaning the paint on the left corner from top to bottom, the left end of the rack 331 must always remain in abutment with the left wing. The left end of the rack 331 abuts against the left wing of the I-beam via the first universal ball 336, allowing the balls in the first universal ball 336 to roll as the spray head 210 moves downward, thereby reducing the friction between the left end of the rack 331 and the left wing. As the spray head 210 cleans the paint on the right corner from top to bottom, the right end of the rack 331 must always remain in contact with the right wing plate. This contact is achieved via the second universal ball transfer 337, allowing the balls in the second universal ball transfer 337 to roll as the spray head 210 moves downward, thereby reducing friction between the right end of the rack 331 and the right wing plate. In this embodiment of the present invention, the ends of the third spring member 334 are connected to the first universal ball transfer 336 and the mounting block 230, respectively. The ends of the fourth spring member 335 are connected to the second universal ball transfer 337 and the mounting block 230, respectively.

[0052] refer to Figure 1 、 Figure 2 and Figure 4, a plurality of self-locking universal wheels 110 are provided at the bottom of the base 100, and the base 100 can move on the ground through the plurality of self-locking universal wheels 110. It is understandable that when the steel surface cleaning equipment is moved, the plurality of self-locking universal wheels 110 on the base 100 can be unlocked, so that the base 100 can move on the ground through the plurality of self-locking universal wheels 110. After the steel surface cleaning equipment is moved into place, the plurality of self-locking universal wheels 110 can be locked to prevent the base 100 from moving on the ground, so that the cleaning process can proceed smoothly. The self-locking universal wheel 110 is a common wheel component and will not be further described here.

[0053] refer to Figure 1 、 Figure 2 and Figure 4 The steel surface cleaning device also includes a plurality of support assemblies 120, which are evenly distributed on the outer wall of the base 100. The base 100 can be supported against the ground through the plurality of support assemblies 120. Specifically, the steel surface cleaning device includes four support assemblies 120, which are respectively arranged on the four corners of the base 100. It can be understood that the plurality of support assemblies 120 play a supporting role on the base 100, preventing the base 100 from shaking during the cleaning process. The support assembly 120 includes a first support rod 121, a second support rod 122 and a foot pad 123. The length direction of the first support rod 121 is perpendicular to the up and down direction, and the second support rod 122 is parallel to the up and down direction. One end of the first support rod 121 is hinged on the outer wall of the base 100, and the second support rod 122 is arranged on the other end of the first support rod 121 so as to be movable up and down. The foot pad 123 is connected to the lower end of the second support rod 122. It is understood that after the section steel surface cleaning device is moved into position, the operator can swing the first support rod 121 so that the other end of the first support rod 121 is away from the base 100. The second support rod 122 is then driven down so that the foot pad 123 on the lower end of the second support rod 122 can rest against the ground, thereby enabling the foot pad 123 to support the base 100. When the section steel surface cleaning device needs to be moved, the operator can raise the second support rod 122 so that the foot pad 123 is out of contact with the ground, and then swing the first support rod 121 so that the other end of the first support rod 121 is close to the base 100. At this time, the section steel surface cleaning device can be moved.

[0054] As an embodiment of the present invention, the support assembly 120 further includes a first magnetic member and a second magnetic member. The first magnetic member is disposed on the base 100, and the second magnetic member is disposed on the other end of the first support rod 121. The first magnetic member and the second magnetic member are capable of magnetically attracting each other, thereby securing the first support rod 121 to the base 100. The first magnetic member and the second magnetic member can be a first magnet and a second magnet, respectively. The first magnet is disposed on the base 100, and the second magnet is disposed on the other end of the first support rod 121. When the steel surface cleaning device is not required, the second magnet on the other end of the first support rod 121 can be magnetically attracted to the first magnet on the base 100 to complete the storage of the first support rod 121. A threaded hole is provided on the other end of the first support rod 121, and an external thread is provided on the outer wall of the second support rod 122. The second support rod 122 is inserted into the threaded hole and threadedly connected to the inner wall of the threaded hole. By rotating the second support rod 122, the second support rod 122 can be raised or lowered. The second support rod 122 is provided with a handle, and the operator can drive the second support rod 122 to rotate through the handle.

[0055] refer to Figure 3 and Figure 7 In an embodiment of the present invention, the cleaning device 200 further includes a water tank, a water pump, a high-pressure water pipe 260, a filter element, and a high-pressure rubber tube 250. The water tank is mounted on the base 100 and is used to store water. The filter element is used to filter impurities in the water. The water tank is connected to one end of the high-pressure water pipe 260 through the filter element. The other end of the high-pressure water pipe 260 is connected to the mounting block 230. One end of the high-pressure rubber tube 250 is connected to the other end of the high-pressure water pipe 260. The other end of the high-pressure rubber tube 250 is connected to the nozzle 210. The high-pressure rubber tube 250 is mounted between the mounting block 230 and the swing block 220. The high-pressure rubber tube 250 can be bent and deformed. The water pump is mounted on the high-pressure water pipe 260. It is understood that after the water pump is activated, the water in the water tank passes through the filter and flows into the high-pressure water pipe 260. The water in the high-pressure water pipe 260 then flows into the high-pressure rubber tube 250. Finally, the water in the high-pressure rubber tube 250 flows into the nozzle 210 and is ejected from the nozzle 210, forming a high-pressure, high-speed jet of water, which can clean impurities such as rust and paint from the surface of the steel section. In this embodiment of the present invention, the high-pressure rubber tube 250 can bend with the swing of the swing block 220. The high-pressure rubber tube 250 is a common pipe component in the high-pressure water jet cleaning device 200 and will not be further described here. The nozzle 210 can be a fan-shaped nozzle 210.

[0056] refer to Figure 2In an embodiment of the present invention, the drive device 400 includes a lifting drive mechanism 410, a first linear drive mechanism 420, and a second linear drive mechanism 430. The lifting drive mechanism 410 is disposed on the base 100. The output end of the lifting drive mechanism 410 is connected to the first linear drive mechanism 420, which in turn is connected to the second linear drive mechanism 430. The output end of the second linear drive mechanism 430 is connected to the support plate 240, and the mounting block 230 is connected to the support plate 240. The lifting drive mechanism 410 is used to drive the first linear drive mechanism 420 to move in the vertical direction, that is, to cause the first linear drive mechanism 420, the second linear drive mechanism 430, the support plate 240, and the mounting block 230 to move in the vertical direction together. The first linear drive mechanism 420 is used to drive the second linear drive mechanism 430 to move in the left-right direction, that is, to cause the second linear drive mechanism 430, the support plate 240, and the mounting block 230 to move in the left-right direction together. The second linear drive mechanism 430 is used to drive the support plate 240 to move in the front-to-back direction, that is, to move the support plate 240 and the mounting block 230 together in the front-to-back direction. Thus, it can be seen that the combined action of the lifting drive mechanism 410, the first linear drive mechanism 420, and the second linear drive mechanism 430 enables the mounting block 230, the swing block 220, and the nozzle 210 to move in the vertical and horizontal directions. The lifting drive mechanism 410, the first linear drive mechanism 420, and the second linear drive mechanism 430 are all common power mechanisms and will not be further described here.

[0057] refer to Figure 2 In an embodiment of the present invention, the steel section surface cleaning device further includes an angle adjustment mechanism 440. The output end of the first linear drive mechanism 420 is connected to the angle adjustment mechanism 440, and the output end of the angle adjustment mechanism 440 is connected to the second linear drive mechanism 430. The angle adjustment mechanism 440 is used to adjust the up and down swing angle of the second linear drive mechanism 430, so that the support plate 240, the mounting block 230, and the swing block 220 can swing up and down to achieve the purpose of adjusting the up and down direction of the nozzle 210. In an embodiment of the present invention, the spray direction of the nozzle 210 is obliquely downward, that is, the water flow ejected from the nozzle 210 acts obliquely downward on the surface of the steel section, so that impurities such as rust and paint on the surface of the steel section can be washed off more effectively.
