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 is a type of steel with a specific cross-section shape, such as I-beams and H-beams. Steel is an important material for building structures. It can serve as a skeleton to bear most of the load, improving the overall strength and seismic resistance of the building. At present, I-beams are often used as pillars of buildings. In order to prevent the I-beams from rusting, a layer of anti-rust paint is usually applied to the surface of the I-beams. As time goes by, the original paint on the surface of the I-beams will crack and peel off, exposing the surface of the I-beams directly to the air, causing the I-beams to rust. At this time, it is necessary to re-apply a layer of anti-rust paint on 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] The steel surface cleaning equipment is a device that uses high-pressure water flow to clean the surface of the steel. The steel surface cleaning equipment is mainly used to remove rust and paint on the surface of the steel. The steel surface cleaning equipment usually includes a nozzle and a driving device. The nozzle can spray high-pressure water flow, and the driving device can drive the nozzle to move in the up and down directions 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 web of the I-beam is removed, the operator needs to adjust the overall direction of the steel surface cleaning equipment so that the nozzle is facing the corner between the web and the wing plate of the I-beam. Only then can the nozzle flush the paint on the corner between the web and the wing plate. It takes a lot of time for the operator to adjust the overall direction of the steel surface cleaning equipment, which increases the downtime of the steel surface cleaning equipment, which is not conducive to improving the cleaning efficiency of the steel surface cleaning equipment.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. 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 hinged on the mounting block 230. The nozzle 210 is arranged on the swing block 220. The nozzle 210 is used to spray water. The driving device 400 is arranged 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 in the up-down direction and the horizontal direction, so that the water sprayed from the nozzle 210 can wash off the paint on the surface of the I-beam. The swing device 300 is arranged on the mounting block 230. The swing device 300 is used to drive the swing block 220 to swing left or right, so that the nozzle 210 can be directed to the left corner or right corner between the web and the wing of the I-beam.

[0037] It should be explained that the reference Figure 6I-beam is a long steel strip with an I-shaped cross section, which is composed of two parallel left and right wing plates and a middle web. The corner between the left wing plate and the web is the left corner, and the corner between the right wing plate and the web is the right corner. In the embodiment of the present invention, the horizontal direction is the left-right direction and the front-back direction.

[0038] In the prior art, the steel surface cleaning device can only flush the paint on one surface of the I-beam at a time. For example, after the steel surface cleaning device flushes the paint on the surface of the left wing plate of the I-beam, the operator needs to move the steel surface cleaning device to the right wing plate of the I-beam. Only then can the steel surface cleaning device clean the paint on the surface of the right wing plate 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 on 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 device so that the nozzle 210 extends into the area between the web and the two wing plates. Then the driving device 400 drives the nozzle 210 to move from top to bottom and reciprocate left and right, so that the water flow sprayed from the nozzle 210 can flush the paint on the surface of the web. On the one hand, in order to ensure the cleaning effect, the nozzle 210 needs to face the action surface, that is, the nozzle 210 needs to face the surface to be cleaned on the I-beam. On the other hand, the paint at the corner is at the intersection of two planes (wing plate and web plate), so the paint at the corner has strong adhesion and is not easy to fall off. As a result, the nozzle 210 cannot effectively wash off the paint at the corner during the process of cleaning the paint on the web plate surface, so the paint on the corner needs to be cleaned specifically in the future.

[0039] After the paint on the surface of the web 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, so that the nozzle 210 can be directed to the corner between the left wing and the web. After the nozzle 210 cleans the paint on the corner between the left wing 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, so that the nozzle 210 can be directed to the corner between the right wing and the web. It can be seen that adjusting the overall direction of the steel surface cleaning equipment takes 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 driving device 400 is arranged on the base 100, and the output end of the driving 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 driving device 400 is connected to the mounting block 230, the swing block 220 is hinged on the mounting block 230, and the nozzle 210 is arranged on the swing block 220, so that the swing block 220 and the nozzle 210 can swing relative to the mounting block 230. In the embodiment of the present invention, the cleaning device 200 is a high-pressure water jet cleaning device 200, and the water flow sprayed by the nozzle 210 is a high-pressure and high-speed water flow, so that the water flow can clean the paint and rust on the surface of the profile. The driving device 400 can drive the mounting block 230 to move in the up-down direction and the horizontal direction, so that the mounting block 230, the swing block 220 and the nozzle 210 can move along a preset path, so that the nozzle 210 can clean the paint on the surface of the steel. The swing device 300 is arranged on the mounting block 230, and 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, so that the nozzle 210 can be directed to the left corner or the right corner between the I-beam web and the wing plate.

[0041] As an embodiment of the present invention, the swing device 300 includes a first waterproof cylinder and a second waterproof cylinder, the cylinder bodies of the first waterproof cylinder and the second waterproof cylinder are both arranged on the mounting block 230, and the cylinder bodies of the first waterproof cylinder and the second waterproof cylinder are respectively arranged on the left and right sides of the mounting block 230, the piston rod of the first waterproof cylinder is transmission-connected to the left side of the swing block 220, and the piston rod of the second waterproof cylinder is transmission-connected to the right side of the swing block 220. It can be understood that when it is necessary to clean the paint on the left corner between the web and the wing of the I-beam, the piston rod of the first waterproof cylinder is retracted, and the piston rod of the second waterproof cylinder is extended, and the piston rod of the second waterproof cylinder can push the swing block 220 to swing to the left, so that the nozzle 210 can swing to the left and face the left corner between the web and the wing of the I-beam. When it is necessary to clean the paint on the right corner between the web and the wing of the I-beam, the piston rod of the second waterproof cylinder contracts 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 face the right corner between the web and the wing of the I-beam.

[0042] It is understandable that when it is necessary to clean the surface of the web of the I-beam, the operator can move the entire steel surface cleaning device so that the nozzle 210 extends into the area between the web and the two wing plates and faces the web. Then the nozzle 210 starts to spray water, and the driving device 400 drives the mounting block 230 to move in the up-down direction and the horizontal direction, so that the nozzle 210 can move according to the preset path, and then the water flow sprayed from the nozzle 210 can wash off the paint on the surface of the web of the I-beam. After the surface cleaning of the web of the I-beam is completed, the steel surface cleaning device does not need to be stopped, and the swing device 300 can drive the swing block 220 to swing to the left, so that the nozzle 210 faces the left corner between the web of the I-beam and the wing plate. Then the driving device 400 first drives the mounting block 230 to rise and then drives the mounting block 230 to slowly descend, so that the water flow sprayed from the nozzle 210 can wash off the paint on the left corner between the web of the I-beam and the wing plate. After the paint on the left corner is cleaned, the steel surface cleaning device does not need to be shut down, and the swing device 300 can drive the swing block 220 to swing rightward, so that the nozzle 210 faces the right corner between the web and the wing of the I-beam. Then the driving device 400 first drives the mounting block 230 to rise and then drives the mounting block 230 to slowly descend, so that the water flow sprayed from the nozzle 210 can wash off the paint on the right corner between the web and the wing of the I-beam. The swing device 300 in the steel surface cleaning device can change the direction of the nozzle 210, so that the nozzle 210 can face the left corner or the right corner between the web and the wing of the I-beam, eliminating the steps for the operator to shut down the steel surface cleaning device and adjust the overall direction, shortening the downtime of the steel surface cleaning device, and thus helping to improve the cleaning efficiency of the 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 the 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 clean the corners of H-shaped steel, 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, the transmission assembly 330 is transmission-connected with the other ends of the first push rod 310 and the second push rod 320, 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. The mounting block 230 is provided with a third guide hole. 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 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 understandable that after the surface cleaning of the web of the I-beam is completed, the surface cleaning equipment of the steel section does not need to be shut down, and the driving device 400 drives the mounting block 230 to rise, so that the nozzle 210 can rise to the desired position. Then the driving device 400 drives the mounting block 230 to move to the left, so that the left end of the rack 331 begins to abut against the left wing plate of the I-beam. The driving device 400 continues to drive the mounting block 230 to move to the left, and at this time the rack 331 moves to the right relative to the mounting block 230. Since the rack 331 is meshed 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. After the swing arm 333 starts to rotate, the right end of the swing arm 333 can push the second push rod 320, so that the second push rod 320 starts to extend and push the right side of the swing block 220. At this time, the second spring member 321 starts to stretch, the first spring member 311 starts to compress, and the first push rod 310 starts to retract, so that the swing block 220 and the spray head 210 on the swing block 220 start to swing to the left. When the swing angle of the swing block 220 can make the spray head 210 face the left corner, the driving device 400 stops driving the mounting block 230 to move further to the left, so that the left end of the rack 331 can always keep against the left wing plate of the I-beam. Then the driving device 400 drives the mounting block 230 to move downward, so that the water flow sprayed from the spray head 210 can wash off the paint on the left corner.

[0046] After the paint skin on the corner between the web and the left wing of the I-beam is cleaned, the surface cleaning equipment of the steel section does not need to be stopped. The driving device 400 drives the mounting block 230 to move to the right. At this time, the left end of the rack 331 is separated from the contact with the left wing, the first spring member 311 begins to stretch, the second spring member 321 begins to compress, and the swing block 220 and the nozzle 210 on the swing block 220 begin to swing to the right. Under the action of the first spring member 311 and the second spring member 321, the other end of the second push rod 320 can push the right end of the swing arm 333, so that the swing arm 333 and the gear 332 start to rotate. The rotating gear 332 can drive the rack 331 to move to the left and reset, and at this time, the swing block 220 and the nozzle 210 on the swing block 220 also swing to the right synchronously. After the nozzle 210 returns to the right, the driving device 400 drives the mounting block 230 to rise, so that the nozzle 210 can rise to the desired position. Then the driving device 400 drives the mounting block 230 to move rightward, so that the right end of the rack 331 begins to abut against the right wing plate of the I-beam. The driving device 400 continues to drive the mounting block 230 to move rightward, and at this time the rack 331 moves leftward relative to the mounting block 230, so that the rack 331 can drive the gear 332 and the swing arm 333 to rotate. After the swing arm 333 starts to rotate, the left end of the swing arm 333 can push the first push rod 310 to extend, so that the first push rod 310 begins 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, so that the swing block 220 and the nozzle 210 on the swing block 220 begin to swing to the right. When the swing angle of the swing block 220 can make the nozzle 210 face the right corner, the driving device 400 stops driving the mounting block 230 to continue to move to the right, so that the right end of the rack 331 can always keep against the right wing plate of the I-beam. Then the driving device 400 drives the mounting block 230 to move downward, so that the water flow sprayed from the nozzle 210 can wash off the paint on the right corner. After the paint on the right corner is cleaned, the driving device 400 drives the mounting block 230 to move to the left, so that the right end of the rack 331 is separated from the abutment with the right wing plate. At this time, the swing block 220 and the nozzle 210 on the swing block 220 can swing back to the left, and the specific process will not be further described.

[0047] refer to Figure 3 , Figure 5 , Figure 6 and Figure 7The transmission assembly 330 further 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, and the two ends of the third spring member 334 are respectively connected to the left end of the rack 331 and the mounting block 230, and the third spring member 334 is used to drive the rack 331 to move to the left, and the two ends of the fourth spring member 335 are respectively connected to the right end of the rack 331 and the mounting block 230, and the fourth spring member 335 is used to drive the rack 331 to move to the right. It can be understood that the left end of the rack 331 is against the left wing plate, and in the process of the rack 331 moving to the right 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 spring member 334 and the fourth spring member 335, the left end of the rack 331 can always be in contact with the left wing plate of the I-beam, ensuring that the nozzle 210 will not swing during the process of cleaning the paint on the left corner, so that the nozzle 210 can always face the left corner. After the paint on the left corner is cleaned, the drive device 400 drives the mounting block 230 to move to the right, so that the left end of the rack 331 is separated from the contact with the left wing plate, at which time the third spring member 334 extends and the fourth spring member 335 retracts. Under the action of the third spring member 334 and the fourth spring member 335, the rack 331 can move quickly to the left, so that the swing block 220 and the nozzle 210 on the swing block 220 can quickly swing back to the right. The right end of the rack 331 is against the right wing plate, and in the process of the rack 331 moving to the left relative to the mounting block 230, the third spring member 334 is stretched and the fourth spring member 335 is compressed. Under the action of the third spring member 334 and the fourth spring member 335, the right end of the rack 331 can always keep contact with the right wing plate of the I-beam, ensuring that the nozzle 210 will not swing during the process of cleaning the paint on the right corner, so that the nozzle 210 can always face the right corner. After the paint on the right corner is cleaned, the drive device 400 drives the mounting block 230 to move to the left, so that the right end of the rack 331 is separated from the contact with the right wing plate, and the third spring member 334 retracts and the fourth spring member 335 extends. Under the action of the third spring member 334 and the fourth spring member 335, the rack 331 can quickly move to the right, so that the swing block 220 and the nozzle 210 on the swing block 220 can quickly swing to the left and return to normal.

[0048] In the 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 specifications of the first spring member 311 and the second spring member 321 are exactly the same, and the specifications of the first push rod 310 and the second push rod 320 are also exactly the same. The first spring member 311 and the second spring member 321 can respectively drive one end of the first push rod 310 and the second push rod 320 to always press against the swing block 220, so that when the swing arm 333 does not rotate, 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, that is, the swing block 220 and the nozzle 210 are returned to the center. Similarly, the specifications of the third spring member 334 and the fourth spring member 335 are exactly the same. 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, that is, the swing block 220 and the nozzle 210 are returned to the center. It needs to be explained that, during 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 keep against the left wing plate or the right wing plate, thereby avoiding the swing block 220 and the nozzle 210 from swinging during 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, both upper and lower sides of the swing block 220 are hinged on the mounting block 230. Specifically, the steel surface cleaning device also includes a fastener, a stud is provided on the upper side of the mounting block 230, a hinge hole is provided on the upper side of the swing block 220, and the stud is inserted into the hinge hole. At this time, the stud is equivalent to a hinge shaft, and the swing block 220 can swing around the axis of the stud. The fastener is threadedly connected to the stud, and the fastener can be against the swing block 220, so that the swing block 220 can be fixed on the mounting block 230. It is understandable that the fastener can be a nut. When the corner of the I-beam does not need to be cleaned, the operator can tighten the nut so that the nut is pressed on the swing block 220, so that the swing block 220 can be fixed on the mounting block 230, thereby avoiding the nozzle 210 from swinging during the cleaning process. As an embodiment of the present invention, a gripping portion is provided on the fastener, and the operator can drive the nut to rotate through the gripping portion, which is convenient for the operator to tighten the fastener.

[0050] refer to Figure 3 , Figure 5 , Figure 6 and Figure 7The swing device 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. The first push rod 310 abuts against the swing block 220 through the first roller 312. The second roller 322 is rotatably connected to one end of the second push rod 320. The second push rod 320 abuts against the swing block 220 through the second roller 322. It can be understood that the first push rod 310 abuts against the swing block 220 through the first roller 312. When the first push rod 310 pushes the left side of the swing block 220, the first roller 312 can rotate, 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 through the second roller 322. When the second push rod 320 pushes the right side of the swing block 220, the second roller 322 can rotate, 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 also includes a first universal ball 336 and a second universal ball 337, which are respectively arranged on the left and right ends of the rack 331. The left end of the rack 331 is against the left wing plate of the I-beam through the first universal ball 336, and the right end of the rack 331 is against the right wing plate of the I-beam through the second universal ball 337. It can be understood that when the nozzle 210 cleans the paint on the left corner from top to bottom, the left end of the rack 331 needs to always keep against the left wing plate, and the left end of the rack 331 is against the left wing plate of the I-beam through the first universal ball 336, so that when the nozzle 210 moves downward, the balls in the first universal ball 336 can roll, thereby reducing the friction between the left end of the rack 331 and the left wing plate. When the nozzle 210 cleans the paint on the right corner from top to bottom, the right end of the rack 331 needs to always be against the right wing plate, and the right end of the rack 331 is against the right wing plate of the I-beam through the second universal ball 337, so that when the nozzle 210 moves downward, the balls in the second universal ball 337 can roll, thereby reducing the friction between the right end of the rack 331 and the right wing plate. In the embodiment of the present invention, the two ends of the third spring member 334 are respectively connected to the first universal ball 336 and the mounting block 230, and the two ends of the fourth spring member 335 are respectively connected to the second universal ball 337 and the mounting block 230.

[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 profile steel surface cleaning device 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 profile steel surface cleaning device 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.

Specifically, the steel surface cleaning device includes four support assemblies 120, and the four support assemblies 120 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, avoiding 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, 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 side wall of the base 100, 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, and the foot pad 123 is connected to the lower end of the second support rod 122. It is understandable that after the profile steel surface cleaning device is moved into place, 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. Then the second support rod 122 is driven down so that the foot pad 123 on the lower end of the second support rod 122 can be against the ground, so that the foot pad 123 can support the base 100. When the profile 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, and the profile 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 arranged on the base 100, and the second magnetic member is arranged on the other end of the first support rod 121, and the first magnetic member and the second magnetic member can be mutually attracted to each other, so that the first support rod 121 is stored and fixed on the base 100. The first magnetic member and the second magnetic member can be respectively a first magnet and a second magnet, the first magnet is arranged on the base 100, and the second magnet is arranged on the other end of the first support rod 121. When the profile steel surface cleaning equipment is not needed, 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, so that the first support rod 121 can be stored. 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 is threadedly connected with 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 an operator can drive the second support rod 122 to rotate by the handle.

It is understandable that after the water pump is started, the water in the water tank passes through the filter and flows into the high-pressure water pipe 260, and then the water in the high-pressure water pipe 260 flows into the high-pressure rubber tube 250, and finally the water in the high-pressure rubber tube 250 flows into the nozzle 210 and is ejected from the nozzle 210 to form a high-pressure and high-speed jet water flow, so that the water flow can flush and clean impurities such as rust and paint on the surface of the steel. In the 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 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 the embodiment of the present invention, the driving device 400 includes a lifting driving mechanism 410, a first linear driving mechanism 420 and a second linear driving mechanism 430.

The second linear drive mechanism 430 is used to drive the support plate 240 to move in the front-to-back direction, that is, the support plate 240 and the mounting block 230 can move in the front-to-back direction together. It can be seen that under the joint action of the lifting drive mechanism 410, the first linear drive mechanism 420 and the second linear drive mechanism 430, the mounting block 230, the swing block 220 and the nozzle 210 can move in the up-down direction and the horizontal direction.
