[0002] A metal 3D printer is an additive manufacturing technology device that uses metal materials for printing. Its principle is to stack metal powder layer by layer, and then use energy sources such as laser beams or electron beams to melt and sinter the metal powder to finally form a solid metal component. During the use of construction steel, due to the difference in temperature and humidity in the environment, it will inevitably suffer damage such as corrosion and wear. Steel corrosion will reduce its durability, affect its strength and rigidity, and even threaten the stability of the structure. Therefore, the use of metal 3D printing technology for additive repair of construction corroded steel has gradually been widely used.

[0003] In the prior art, rectangular steel is usually used to build building frames. When used for a long time, its surface is prone to corrosion.

[0048] Embodiment 1:

[0049] See also Figure 1-10The present invention provides a building corrosion steel additive processing device, comprising a mounting plate 1, and also comprising a positioning frame 2, wherein two positioning frames 2 are provided and one of the positioning frames 2 is fixed to the outer surface of the mounting plate 1, and a positioning frame 3 is fixed to the top opposite surfaces of the two positioning frames 2, and two arc grooves 4 are symmetrically distributed on the outer surface of one end of the positioning frame 3, and a rotating sleeve rod 5 rotatably connected to the outer surface of the end of the positioning frame 3 is provided on the outer side of each arc groove 4, and a rotating sleeve 6 rotatably connected to the inner wall of the rotating sleeve rod 5 is provided through the interior of the arc groove 4, and a magnetic rod 7 is inserted into the inner wall of the rotating sleeve 6;

[0050] It should be noted that a 3D scanner 21 is installed at one end of the mounting plate 1 close to the positioning frame 2, and a metal 3D printer is installed at the rear end thereof. The 3D printer is a portable 3D printer, which is installed on the mounting plate 1 in a detachable connection manner, not shown in the figure. The principle of repairing architectural corroded steel using 3D printing technology is as follows: the 3D scanner 21 creates a point cloud by laser scanning the geometric surface of the object, and interpolates the point cloud data into the surface shape of the object. The denser the point cloud, the more accurate the model can be created, thereby completing the 3D reconstruction process. The metal 3D printer uses the detection and analysis results of the cloud data obtained by the 3D scanner 21, designs a 3D model of the required repair part by calculation, and then discretizes the model. It is a series of ordered units, which are discretized according to a certain thickness, and the original three-dimensional model is converted into a series of layers. Then, according to the contour information of each layer, the processing parameters are input, and the system automatically generates a numerical control code. Finally, a series of layers are formed and automatically connected to finally obtain a three-dimensional physical entity, thereby completing the additive repair of the surface of the building steel. The additive repair of the building steel by the three-dimensional scanner 21 and the metal 3D printer is a conventional setting in the field, so it will not be described in detail here. This case aims to describe in detail the preparation operation of moving the mounting plate 1 equipped with the three-dimensional scanner 21 and the metal 3D printer to the corrosion area of ​​the building square steel for additive repair;

[0051] A fixing frame 8, the fixing frame 8 is arranged at the center above the two magnetic bars 7, and a pressing and positioning mechanism 9 is arranged on the periphery of the positioning frame 3 for the two magnetic bars 7 and the fixing frame 8 to move synchronously;

[0052] Traveling wheels 10, two of which are coaxially rotatably mounted on the outer surface of the fixed frame 8, a central push plate 11 is fixed on the outer surface of the positioning frame 2 away from the mounting plate 1, two symmetrically distributed push rods 12 are slidably penetrated through the bottom outer surface of the central push plate 11, and the outer ends of the two push rods 12 are detachably connected to a push block 13, and a forward mechanism 14 for synchronous movement of the two traveling wheels 10 and the push block 13 is arranged inside the positioning frame 3;

[0053] It should be noted that the positioning frame 2 is U-shaped with one end open, and in the initial state, through the action of the clamping positioning mechanism 9, the two rotating sleeves 6 are located at the bottom of the arc groove 4, and the two rotating sleeves 6 can form a certain magnetic adsorption effect through the magnetic rods 7 inside them, which effectively improves the stability of the rotating sleeve 6 on the bottom surface of the building square steel. At the same time, the fixed frame 8 is located at the highest position at the top of the positioning frame 3. At this time, the distance between its traveling wheel 10 and the rotating sleeve 6 is significantly greater than the thickness of the building square steel, so that it is convenient to feed the mounting plate 1 into the opening of the positioning frame 3. Subsequently, through the adjustment processing of the clamping positioning mechanism 9, the traveling wheel 10 and the two rotating sleeves 6 move synchronously toward the top and bottom surfaces of the building square steel respectively, so that the two traveling wheels 10 and the two rotating sleeves 6 are in the vertical direction. An isosceles triangle shape is formed, and the traveling wheel 10 is pressed and installed on the top surface of the building square steel, and the two rotating sleeves 6 are in contact with the bottom surface of the building square steel, so that the mounting plate 1 equipped with the three-dimensional scanner 21 and the metal 3D printer is stably placed on the top surface of the building square steel, and then the traveling wheel 10 is driven by the forward mechanism 14 to move on the surface of the building square steel, so that the mounting plate 1 equipped with the three-dimensional scanner 21 and the metal 3D printer is smoothly transferred to the corrosion area of ​​the building square steel. It does not require the staff to carry the three-dimensional scanner 21 and the mounting plate 1 of the metal 3D printer to the corrosion area of ​​the building square steel, which simplifies the preparation steps for additive processing of the building square steel, avoids the occurrence of safety accidents to a certain extent, and greatly improves the safety performance of additive repair of the building square steel;

[0054] Positioning rods 15, four positioning rods 15 are arranged and the four positioning rods 15 are arranged in a rectangular shape and slidably mounted on the inner walls of the two positioning frames 2, rollers 16 are installed at the opposite ends of the two positioning rods 15 on the same side, and a veneer positioning mechanism 17 for the four rollers 16 to move synchronously is arranged between the two positioning frames 2;

[0055] It should be noted that when the fixed frame 8 and the rotating sleeve 6 are at the maximum distance, since the roller 16 is located below the traveling wheel 10 and is always at the same height in the vertical direction, it is necessary to ensure that the distance between the roller 16 and the rotating sleeve 6 is greater than the thickness of the building square steel, so that the positioning frame 3 can be easily fitted with the top surface of the building square steel through the roller 16 until the four rollers 16 are respectively located on the outer surface of the building square steel, and the traveling wheel 10 is placed on the top surface of the building square steel;

[0056] The veneer positioning mechanism 17 is set to move synchronously with the clamping positioning mechanism 9, so that the four rollers 16 synchronously move toward the center of the outer surfaces at both ends of the building square steel, forming the four rollers 16 in contact with the side surfaces of the building square steel. Then the rollers 16 move synchronously through the forward mechanism 14, so that the two traveling wheels 10 move on the top surface of the building square steel and the four rollers 16 move on the outer surfaces at both ends of the building square steel, further improving the stability of the mounting plate 1 equipped with the three-dimensional scanner 21 and the metal 3D printer when it moves to the target area.

[0057] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Fig.10 As shown, it is worth specifically explaining that the clamping and positioning mechanism 9 includes a lifting ring 91, which is sleeved on the outer surfaces of the ends of the two rotating sleeves 6, and two symmetrically distributed lifting rack rods 92 are fixed on the top surface of the lifting ring 91, and a fixing rod 93 is commonly fixed to the top ends of the two lifting rack rods 92, and a guide sleeve 94 fixed to the outer surface of the end of the positioning frame 3 is arranged above the fixing rod 93, and a clamping rod 95 is slidably penetrated through the inner wall of the guide sleeve 94, and the bottom end of the clamping rod 95 is fixed to the top surface of the fixing rod 93, and the outer surface of the clamping rod 95 is provided with a compression spring 96 fixed to the opposite surface of the guide sleeve 94 and the fixing rod 93;

[0058] The mounting frame 97 is fixed to the top surface of the positioning frame 3. An electric push rod 98 is fixed to the top inner wall of the mounting frame 97. A T-block 99 is fixed to the output end of the electric push rod 98. A connecting piece 910 is slidably penetrated through the top surface of the positioning frame 3. The top and bottom of the connecting piece 910 are fixed to the opposite surfaces of the T-block 99 and the fixing frame 8 respectively.

[0059] The reversing gear 911 is provided with two reversing gears 911 and is coaxially rotatably mounted on the outer surface of the end of the positioning frame 3. Two symmetrically distributed pressing rack rods 912 are provided on the outer side of the reversing gear 911. The top ends of the two pressing rack rods 912 are fixed to the bottom surface of the T-block 99. The reversing gear 911 is meshedly connected with the pressing rack rod 912 and the lifting rack rod 92 located on the same side.

[0060] It should be noted that when the positioning frame 3 and the mounting plate 1 are placed on the building square steel, the positioning frame 3 is delivered from the outer surface of the end of the building square steel to the periphery of the building square steel, and the bottom surface of the positioning frame 3 is supported. At this time, the electric push rod 98 drives the T-block 99 to move downward at the mounting frame 97, and the transmission action of the connecting piece 910 drives the fixed frame 8 and the traveling wheel 10 to gradually move toward the top surface of the building square steel. At the same time, the rack rod 912 is pressed to move downward synchronously. The meshing transmission action of the rack rod 912, the reversing gear 911 and the lifting rack rod 92 is used to make the two lifting rack rods 92 drive the lifting ring 91 to move upward synchronously, and the fixing rod 93 and the clamping rod 95 are used to limit the position. The compression spring 96 is compressed on the guide sleeve 94, and as the lifting ring 91 gradually moves upward, the rotating sleeve 6 and the internal magnetic rod 7 are driven by the limiting action of the rotating sleeve rod 5, so that the two rotating sleeves 6 are synchronously rotated upward in the arc groove 4, so that the two rotating sleeves 6 are rotated upward in an arc shape while the two traveling wheels 10 are synchronously moved downward, thereby completing the compression and positioning installation of the two traveling wheels 10 and the two rotating sleeves 6 on the top and bottom surfaces of the building square steel, and preparing for the installation plate 1 equipped with a three-dimensional scanner 21 and a metal 3D printer to be smoothly moved to the corrosion area through the forward mechanism 14, so as to ensure the accuracy of the subsequent additive repair of the corrosion area of ​​the building square steel by the 3D printer.

[0061] Further as Figure 2 and Figure 7 As shown, it is worth to explain in detail that the connecting member 910 includes a fixed sleeve 9101, which is located inside the positioning frame 3 and fixed to the top surface of the fixing frame 8, and the inner wall of the fixed sleeve 9101 is slidably connected with a pressing rod 9102, which slides through the top surface of the positioning frame 3 and is fixed to the bottom surface of the T-block 99;

[0062] A pressing spring 9103, which is disposed inside the fixed sleeve 9101, and two ends of the pressing spring 9103 are respectively fixed to the opposite surfaces of the fixed sleeve 9101 and the pressing rod 9102;

[0063] It should be noted that the fixed frame 8 can perform telescopic movement in the positioning frame 3 through the fixed sleeve 9101 and the pressing rod 9102. Since the movement of the two rotating sleeves 6 in the arc groove 4 is a fixed trajectory, the fixed frame 8 can perform reverse compression movement through the connecting piece 910, thereby providing more possibilities for the traveling wheel 10 and the rotating sleeve 6 to compress and position the building square steel, and thus can be used for compressing and positioning building square steels of different thicknesses.

[0064] Further as Figure 1 , Figure 7 and Fig. 9As shown, it is worth specifically explaining that the forward mechanism 14 includes a transmission bevel gear 141, which is coaxially fixed with the two traveling wheels 10, and the inner wall of the fixed frame 8 is rotatably connected with a driving bevel gear 142, and the driving bevel gear 142 is meshedly connected with the transmission bevel gear 141, and the periphery of the fixed frame 8 is provided with a driving motor 143 coaxially connected with the driving bevel gear 142;

[0065] Incomplete gears 144, two incomplete gears 144 are provided and are coaxially fixed with the transmission bevel gear 141, the inner wall of the fixed frame 8 is slidably penetrated by two symmetrically distributed U-shaped rack rods 145, the U-shaped rack rods 145 are meshingly connected with the incomplete gears 144 close to each other, and the outer surface of the U-shaped rack rods 145 is fixed with the propulsion rods 12 close to each other;

[0066] It should be noted that the driving motor 143 drives the driving bevel gear 142 to rotate synchronously, and the meshing transmission of the driving bevel gear 142 and the transmission bevel gear 141 causes the two traveling wheels 10 and the two incomplete gears 144 to rotate in the fixed frame 8. Since the traveling wheels 10 and the rotating sleeve rod 5 are pressed by the pressing and positioning mechanism 9, the traveling wheels 10 are rolled on the surface of the building square steel through the friction between the traveling wheels 10 and the surface of the building square steel, so that the mounting plate 1 equipped with the three-dimensional scanner 21 and the metal 3D printer is smoothly moved above the building square steel. At this time, the setting of the magnetic rod 7 in the rotating sleeve 6 can further increase the surface friction between the traveling wheels 10 and the building square steel, and further ensure the stability of the movement of the traveling wheels 10 on the surface of the building square steel.

[0067] When the incomplete gear 144 is continuously rotating, the meshing transmission between the incomplete gear 144 and the U-shaped rack rod 145 causes the U-shaped rack rod 145 to reciprocate on the fixed frame 8, thereby driving the push block 13 to reciprocate and scrape the surface of the building square steel through the connection of the propulsion rod 12. At this time, the spacing value between the push block 13 and the fixed frame 8 is reciprocated. Compared with the push block 13 moving synchronously with the fixed frame 8 without changing the spacing value, it can better scrape the debris or corroded rust residue on the surface of the building square steel, which can effectively improve the stability of the traveling wheel 10 walking on the surface of the building square steel, and can also clean the corroded area of ​​the square steel to a certain extent, thereby providing convenience for subsequent additive repair.

[0068] Further as Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, it is worth specifically explaining that a wiping wheel 18 is provided below the mounting plate 1, and the bottom end of the U-shaped rack rod 145 is detachably connected to the frame of the wiping wheel 18;

[0069] It should be noted that the wiping wheel 18 is configured to perform synchronous reciprocating motion with the U-shaped rack rod 145, so as to further remove or homogenize the scraped rust or debris, thereby improving the surface flatness and cleanliness of the corroded area of ​​the building square steel, thereby providing accuracy for the three-dimensional scanning and 3D printing additive processing of the three-dimensional scanner 21 and the metal 3D printer on the mounting plate 1, and improving its additive repair effect;

[0070] It should be noted that the wiping wheel 18 is detachable, which can be easily replaced or cleaned, thereby improving the surface flatness and cleanliness of the corroded area of ​​the building square steel, and providing technical support for additive repair by 3D printers.

[0071] Further as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, it is worth to explain in detail that the veneer positioning mechanism 17 includes a limit block 171, which is arranged inside the positioning frame 2, and a vertical rod 172 is fixed to the top surface of the limit block 171, and the vertical rod 172 slides through the top surface of the positioning frame 2 and is fixed to the bottom surface of the T-block 99;

[0072] Sliding frames 173, two sliding frames 173 are provided and both sliding frames 173 are slidably sleeved on the outer surface of the end of the limit block 171, one outer surface of the sliding frame 173 is hinged to the outer surface of the positioning frame 2 by a first connecting rod 174, and the other outer surface of the sliding frame 173 is hinged to the outer surface of the positioning rod 15 by a second connecting rod 175;

[0073] It should be noted that when the T-block 99 moves downward, the vertical rod 172 drives the limit block 171 to move downward synchronously in the positioning frame 2. At this time, through the connecting action of the first connecting rod 174, the sliding frame 173 moves toward the center of the limit block 171 in the limit frame, and through the connecting action of the second connecting rod 175, the positioning rod 15 slides in the positioning frame 2 toward the center of the positioning frame 2, so that the four rollers 16 synchronously move toward the end surface of the building square steel, so that the four rollers 16 are distributed in a rectangular shape and contact the outer surfaces of both ends of the building square steel. The positioning and clamping mechanism cooperates with the rotating sleeve 6 and the traveling wheel 10 to perform compression and positioning processing, thereby further improving the positioning stability of the positioning frame 3 and the mounting plate 1 on the building square steel, and greatly ensuring the stability of the subsequent traveling wheel 10 and the roller 16 in the traveling processing on the surface of the building square steel.

[0074] This embodiment has the following working process: when performing additive processing on the corrosion area of ​​the building square steel, firstly, the portable 3D printer and the 3D scanner 21 are installed on the mounting plate 1, and then the positioning frame 3 is inserted into the surface of the building square steel from the two rollers 16 on the positioning frame 2 until the center position of the two traveling wheels 10 is aligned with the center position of the building square steel, and the positioning frame 3 is auxiliary supported. At this time, the traveling wheel 10 and the rotating sleeve 6 are synchronously adjusted by the pressing positioning mechanism 9, that is, the two traveling wheels are aligned. 10 synchronously moves toward the top surface of the building square steel and the two rotating sleeves 6 rotate upward in an arc shape, so that the two traveling wheels 10 and the two rotating sleeves 6 are distributed in an isosceles triangle in the vertical direction, and the traveling wheels 10 and the rotating sleeves 6 are respectively pressed and positioned and installed on the top surface and the bottom surface of the building square steel, thereby preliminarily completing the pressing positioning treatment of the positioning frame 3 and the mounting plate 1. In addition, the magnetic rod 7 arranged in the rotating sleeve 6 produces a certain magnetic adsorption effect with the bottom surface of the building square steel, further improving the pressing effect of its pressing positioning treatment;

[0075] The veneer positioning mechanism 17 moves synchronously with the pressing positioning mechanism 9. At this time, the four rollers 16 move toward the center on the two positioning frames 2 through the four positioning rods 15, so that the four rollers 16 are in contact with the outer surfaces of both ends of the building square steel for veneer processing, and the pressing positioning of the traveling wheel 10 and the rotating sleeve rod 5 and the adsorption positioning of the magnetic rod 7 are combined, thereby greatly improving the stability of the positioning frame 3, the positioning frame 2 and the mounting plate 1 in the installation processing on the surface of the building square steel;

[0076] By setting the forward mechanism 14, the positioning frame 3, the positioning frame 2 and the mounting plate 1 that have been positioned are moved on the surface of the building square steel with the rolling action of the traveling wheel 10 and the roller 16, and at the same time, the push block 13 and the wiping wheel 18 reciprocate with the fixed frame 8. Through the reciprocating movement of the push block 13, the top surface of the building square steel is scraped back and forth, which can not only effectively improve the stability of the traveling wheel 10 walking on the surface of the building square steel, but also clean the corroded area of ​​the square steel to a certain extent, thereby providing convenience for subsequent additive repair. Through the reciprocating motion of the wiping wheel 18, the surface of the building square steel is further cleaned or homogenized, and the surface flatness and cleanliness of the corroded area of ​​the building square steel are improved, thereby providing accuracy for the three-dimensional scanning and 3D printing additive processing of the three-dimensional scanner 21 and the metal 3D printer on the mounting plate 1, and improving its additive repair effect.

[0077] Embodiment 2:

[0078] Based on the first embodiment, Figure 3 , Figure 6 and Fig. 9As shown, it is worth specifically explaining that a diverter block 19 is fixed to the bottom outer surface of the central push plate 11, and swing mechanisms 20 cooperating with two rollers 16 are arranged on both sides of the diverter block 19. The swing mechanism 20 includes a swing scraper rod 201, which is arranged at two and both are rotatably mounted on the outer surface of the central push plate 11 away from the diverter block 19. A rotating disk 202 is coaxially fixed above the roller 16, and a rotating rod 203 is fixed to the top surface of the rotating disk 202;

[0079] A track groove 204, the track groove 204 is opened at the end of the swing scraper rod 201, and the top end of the rotating rod 203 is located inside the adjacent track groove 204;

[0080] The cross-section of the two swing scraper rods 201 is set in an eight-shaped configuration, and the outer surface of the end of the swing scraper rod 201 and the outer surface of the top of the push block 13 are both set in an inclined slope;

[0081] It should be noted that the debris and corrosion rust residue on the surface of the building square steel are scraped off by the reciprocating motion of the push block 13, and a small amount of debris and corrosion rust residue reaches the diverter block 19. The diverter block 19 is pushed forward along with the forward mechanism 14, and the debris and corrosion rust residue can be diverted and pushed to the swing scraper rod 201 for scraping.

[0082] On the basis of the first embodiment, the present embodiment also has the following working process: when the roller 16 rolls on the outer end surface of the building square steel, its turntable 202 and the rotating rod 203 rotate accordingly. Since the rotating rod 203 is always inside the track groove 204, the swinging scraper rod 201 performs a swinging scraping process on the top surface of the building square steel, and cooperates with the reciprocating swinging scraping of the push block 13 to further improve the surface flatness and cleanliness of the top surface of the building square steel. At the same time, the reciprocating wiping process of the wiping wheel 18 on the surface of the building square steel can be cooperated to further ensure the surface cleanliness of the corrosion area of ​​the building square steel, thereby providing accuracy for the three-dimensional scanning and 3D printing additive processing of the three-dimensional scanner 21 and the metal 3D printer on the mounting plate 1, and further improving its additive repair effect.

[0083] In summary, in combination with the two embodiments, it can be known that: through the mutual cooperation of the clamping positioning mechanism 9 and the veneer positioning mechanism 17, the two walking wheels and the two rotating sleeves 6 move in opposite directions, that is, the traveling wheel 10 and the rotating sleeve 6 are respectively clamped and positioned and installed on the top and bottom surfaces of the building square steel, completing the clamping positioning treatment of the positioning frame 3 and the mounting plate 1. In addition, the magnetic rod 7 arranged in the rotating sleeve 6 produces a certain magnetic adsorption effect with the bottom surface of the building square steel, further improving the clamping effect of its clamping positioning treatment. At the same time, the four rollers 16 are respectively moved toward the center on the two positioning frames 2 through the four positioning rods 15, so that the four rollers 16 are in contact with the outer surfaces of the two ends of the building square steel for veneer treatment, and the clamping positioning of the traveling wheel 10 and the rotating sleeve rod 5 and the adsorption positioning effect of the magnetic rod 7 are cooperated, thereby greatly improving the stability of the positioning frame 3, the positioning frame 2 and the mounting plate 1 in the installation treatment on the surface of the building square steel.

[0084] By setting the advancing mechanism 14, the traveling wheel 10 and the roller 16 are advanced on the surface of the building square steel, and at the same time, the push block 13 and the wiping wheel 18 are reciprocated between the fixing frame 8. The reciprocating movement of the push block 13 can effectively improve the stability of the traveling wheel 10 on the surface of the building square steel, and can also clean the corroded area of ​​the square steel to a certain extent, thereby providing convenience for subsequent additive repair. The reciprocating movement of the wiping wheel 18 improves the surface flatness and cleanliness of the corroded area of ​​the building square steel, thereby cleaning the three-dimensional structure of the installation plate 1. The three-dimensional scanner 21 and the metal 3D printer provide accuracy for three-dimensional scanning and 3D printing additive processing, thereby improving the additive repair effect. In addition, the mounting plate 1 equipped with the three-dimensional scanner 21 and the metal 3D printer is smoothly transferred to the corrosion area of ​​the building square steel. It is unnecessary for the staff to carry the three-dimensional scanner 21 and the mounting plate 1 of the metal 3D printer to the corrosion area of ​​the building square steel, thereby simplifying the preparation steps for additive processing of the building square steel, avoiding the occurrence of safety accidents to a certain extent, and greatly improving the safety performance of additive repair of the building square steel.

[0085] The setting of the swing mechanism 20 moves synchronously with the roller 16, so that the swing scraper rod 201 performs swing-type scraping treatment on the top surface of the building square steel, and cooperates with the reciprocating swing scraping of the push block 13 to further improve the surface flatness and cleanliness of the top surface of the building square steel. At the same time, it can cooperate with the wiping wheel 18 to perform reciprocating wiping treatment on the surface of the building square steel, further ensuring the surface cleanliness of the corrosion area of ​​the building square steel, thereby providing accuracy for the three-dimensional scanning and 3D printing additive processing of the three-dimensional scanner 21 on the mounting plate 1 and the metal 3D printer, and further improving its additive repair effect.
