[0023] The technical solutions of the present invention will be further described in detail below with reference to the drawings.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0025] Embodiment 1

[0026] Refer to Figure 1 And Figure 4, which is the first embodiment of the present invention. This embodiment provides a rust removal device for civil engineering plates. The rust removal device for civil engineering plates includes a rust removal component 100 and a flipping component 200. The rust removal component 100 is used to perform rust removal operations on steel plates. During the rust removal process, the steel plate can be flipped through the flipping component 200, enabling automatic rust removal operations on both sides without manual flipping, greatly improving the rust removal efficiency.

[0027] Specifically, the rust removal component 100 includes a workbench 101, support columns 102, a laser rust remover 103, a placement member 104, and a feeding member 105. The support columns 102 are fixed at the four corners of the bottom of the workbench 101. A work hole S is provided on the workbench 101. The laser rust remover 103 is fixed on the top of the workbench 101 and is located above the work hole S. The placement member 104 is fixed inside the support columns 102, and the feeding member 105 is fixed at the bottom of the placement member 104.

[0028] The laser rust remover 103 is fixed above the work hole S through a bracket. A driving mechanism is provided on the bracket, which can drive the laser rust remover 103 to move, facilitating rust removal operations on various positions of the steel plate. Both of them are prior arts, and those skilled in the art can clearly understand them and will not be elaborated here. A plurality of cleaning holes are provided on the inner wall of the work hole S, and its outside is connected to an external blower to clean impurities during the rust removal process and keep the working space clean. The placement member 104 is used to store the steel plate, and the feeding member 105 is used to push the steel plate under the laser rust remover 103 for rust removal operations.

[0029] The flipping component 200 is arranged on the top of the placement member 104 and includes side plates 201, a flipping member 202, a clamping member 203, a driving member 204, and a limiting member 205. The side plates 201 are fixed on the top of the placement member 104. The flipping member 202 is arranged on one side of the side plates 201. The clamping member 203 is fixed on one side of the flipping member 202. The driving member 204 is arranged on the top of the side plates 201, and the limiting member 205 is arranged on the clamping member 203.

[0030] The side plates 201 are rectangular. A rectangular hole is provided on the side wall of the work hole S. The top of the side plates 201 extends through the rectangular hole to the upper part of the work hole S for installing and supporting other components. The flipping member 202 is used to drive the clamping member 203 to rotate. The clamping member 203 holds the steel plate at its end. By driving the rotation of the clamping member 203 by the flipping member 202, the steel plate can be flipped, facilitating rust removal operations on both sides. The driving member 204 drives the flipping member 202 to move up and down on the side of the side plates 201, driving the steel plate into the work hole S for rust removal operations. The limiting member 205 is used to limit the steel plate to prevent it from falling during the flipping process.

[0031] Embodiment 2

[0032] Refer toFigures 1 to 4 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0033] Specifically, the placing member 104 includes a support plate 104a and a placing box 104b. The support plate 104a is fixed to the inner side of the support column 102, and the placing box 104b is fixed to the top of the support plate 104a.

[0034] The support plate 104a is fixed between the four support columns 102. The side plate 201 is fixed to the top of the support plate 104a. The placing box 104b is rectangular, and a plurality of steel plates can be stored inside it. An outlet channel is also opened at the bottom, and the steel plates can be pushed out from this outlet channel to below the working hole S through the feeding member 105.

[0035] The feeding member 105 includes a fixed frame 105a, a sliding plate 105b, a limiting plate 105c, and an electric push rod 105d. The fixed frame 105a is fixed to the bottom of the support plate 104a. The sliding plate 105b slides on the top of the fixed frame 105a. The limiting plate 105c is fixed to the bottom of the sliding plate 105b and slides inside the fixed frame 105a. The electric push rod 105d is fixed inside the fixed frame 105a, and its end is fixed to the limiting plate 105c.

[0036] The fixed frame 105a is rectangular, and a rectangular chamber is provided inside it. A rectangular hole for communicating the placing box 104b and the fixed frame 105a is opened on the support plate 104a. The sliding plate 105b slides in this rectangular hole, and its cross-section is T-shaped to prevent deviation during movement. The limiting plate 105c is rectangular and fits against the inner wall of the fixed frame 105a. There are two of them located at the outer end and the middle of the sliding plate 105b respectively, used to limit the sliding plate 105b and prevent it from deviating during left and right movement. The end of the electric push rod 105d is fixed to the limiting plate 105c in the middle of the sliding plate 105b. When it expands and contracts, it can drive the limiting plate 105c and the sliding plate 105b to move left and right.

[0037] The feeding member 105 further includes a pushing plate 105e, a fixing block 105f, and a first spring 105g. A sliding hole K is opened at the end of the sliding plate 105b. The pushing plate 105e slides in the sliding hole K. The fixing block 105f is fixed to one side of the limiting plate 105c and is located below the pushing plate 105e. Both ends of the first spring 105g are fixed to the pushing plate 105e and the fixing block 105f respectively.

[0038] The top of the outer side of the push plate 105e is beveled. It can move up and down in the sliding hole K. A rectangular hole is opened at its bottom. The fixing block 105f is located in the rectangular hole to limit the push plate 105e and prevent it from disengaging downward from the sliding hole K. The first spring 105g applies an upward force to the push plate 105e to disengage it. In the initial state, the top end of the push plate 105e is above the support plate 104a. When the electric push rod 105d drives the sliding plate 105b to move to the right, the push plate 105e will drive the bottommost steel plate to move. When it moves leftward to reset, due to the beveled surface of the push plate 105e, it will be pushed downward by the steel plate, preventing it from hindering the reset of the sliding plate 105b.

[0039] Embodiment 3

[0040] Referring to Figures 4 to 8 , this is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, the flipping member 202 includes a moving plate 202a, a rotating rod 202b, a driving tube 202c, a gear 202d, and a toothed plate 202e. The moving plate 202a slides on one side of the side plate 201. A moving groove M is opened inside it. The rotating rod 202b is rotatably connected in the moving groove M. The driving tube 202c slides in the moving groove M and cooperates with the rotating rod 202b. The gear 202d is fixed to the end of the driving tube 202c. The toothed plate 202e is fixed to one side of the side plate 201 and cooperates with the gear 202d.

[0042] The moving plate 202a is rectangular. The rotating rod 202b is rotatably connected in the moving groove M through a bearing. One end of it is inside the moving groove M, and the other end extends to the outside of it. The driving tube 202c slides on the surface of the rotating rod 202b. Limiting strips are fixed around the rotating rod 202b. Limiting grooves for its sliding are opened on the inner wall of the driving tube 202c. Thus, when the driving tube 202c rotates, it can drive the rotating rod 202b to rotate. The toothed plate 202e is located in the middle of the side plate 201. When the gear 202d slides on the toothed plate 202e, both the gear 202d and the driving tube 202c will rotate 180 degrees to achieve the purpose of flipping. When the gear 202d and the driving tube 202c move outward, the gear 202d will separate from the toothed plate 202e. At this time, when the moving plate 202a moves downward, they will not mesh and rotate.

[0043] The flipping member 202 further includes a fixing ring 202f, a pulling plate 202g, and a convex rod 202h. The fixing ring 202f is fixed to the surface of the driving tube 202c. A limiting groove P is opened in the moving plate 202a. The pulling plate 202g slides in the limiting groove P and cooperates with the fixing ring 202f. The convex rod 202h is fixed to the outside of the pulling plate 202g.

[0044] The pull plate 202g is L-shaped and is divided into two parts. One part is an arc-shaped frame that slides on the surface of the fixed ring 202f, and the other part is rectangular and extends into the limit groove P. When it moves, it can drive the drive tube 202c to move through the fixed ring 202f. The end of the convex rod 202h extends outside the limit groove P, and a groove for its sliding is provided on the side of the moving plate 202a, enabling it to move.

[0045] The flipping member 202 further includes a trigger plate 202i, which is fixed to the top and bottom of one side of the side plate 201. An inclined groove V is provided on its inner side and cooperates with the convex rod 202h.

[0046] There are two trigger plates 202i, which are L-shaped. When the moving plate 202a moves to the top trigger plate 202i, the convex rod 202h slides in the top inclined groove V and drives the fixed ring 202f and the drive tube 202c to move outward, thus preventing the gear 202d from engaging with the toothed plate 202e when the moving plate 202a moves downward. When the moving plate 202a moves downward, the convex rod 202h slides in the bottom inclined groove V, causing the drive tube 202c to move inward. At this time, when the moving plate 202a moves upward, the gear 202d will engage with the toothed plate 202e, driving the steel plate to flip.

[0047] A guide rod is also fixed in the middle of the trigger plate 202i, and a guide groove for cooperation is provided in the middle of the rotating rod 202b. That is, when the gear 202d is separated from the toothed plate 202e, the guide rod will be inserted into the guide groove correspondingly, which can limit the rotating rod 202b and the steel plate to prevent the steel plate from shifting or falling during the up and down movement and rust removal process.

[0048] The clamping member 203 includes a clamping plate 203a and an extension rod 203b. The clamping plate 203a is fixed to the end of the rotating rod 202b, and the extension rod 203b is fixed to one side of the clamping plate 203a.

[0049] The clamping plate 203a is U-shaped, and the side close to the working hole S is used to place the steel plate. There are four extension rods 203b, which are symmetrically fixed at the four corners of the opening side of the clamping plate 203a to further fasten the steel plate and prevent it from shifting during the flipping and rust removal process.

[0050] The driving member 204 includes a driving block 204a, a motor 204b, and a threaded rod 204c. A limit hole U is provided on the side plate 201. The driving block 204a is fixed to the side of the moving plate 202a and slides in the limit hole U. The motor 204b is fixed to the top of the side plate 201, and the threaded rod 204c is fixed to the output end of the motor 204b and is threadedly connected to the driving block 204a.

[0051] The driving block 204a is T-shaped, and its outer side contacts the inner wall of the limiting hole U. It is used to fix and limit the moving plate 202a, drive it to move up and down, and prevent it from falling during the moving process. Installation rods are fixed on both sides of the motor 204b to fix the motor 204b and make it more stable. The threaded rod 204c is threadedly connected to the driving block 204a. The motor 204b drives the threaded rod 204c to rotate, thereby driving the driving block 204a and the moving plate 202a to move up and down. The driving principle and program of the motor are both prior arts, and those skilled in the art can set them as needed, which will not be elaborated here.

[0052] The limiting member 205 includes a plug rod 205a, a top plate 205b, a second spring 205c and a magnet 205d. A jack T is formed on the clamping plate 203a. The plug rod 205a slides in the jack T. The top plate 205b is fixed to the top end of the plug rod 205a. Both ends of the second spring 205c are fixed to the top plate 205b and the clamping plate 203a respectively. The magnet 205d is fixed to the top of the support plate 104a and is located below the clamping plate 203a.

[0053] There are two plug rods 205a, which are symmetrically arranged on the clamping plate 203a. The top plate 205b is fixed to the top ends of the two plug rods 205a. The second spring 205c applies a force to the plug rod 205a and the top plate 205b to move in the direction of the clamping plate 203a, thereby preventing the steel plate from falling or shifting after being flipped. A convex plate can be fixed to the side of the steel plate by welding or threaded connection, etc. Two holes are formed on it to facilitate the fixing of the steel plate by the plug rod 205a. Magnetic sheets with the same magnetic poles as the magnet 205d are provided on the surfaces of the plug rod 205a and the top plate 205b. The magnet 205d applies a repulsive force to the plug rod 205a and the top plate 205b. When the top plate 205b moves upward and the moving plate 202a moves downward to the lowest position, the magnet 205d pushes the plug rod 205a and the top plate 205b upward, so that the plug rod 205a disengages from the hole, and at this time the steel plate can be pushed out. When the top plate 205b moves downward and the moving plate 202a moves downward to the lowest position, the magnet 205d still pushes the plug rod 205a and the top plate 205b upward, so that the plug rod 205a can be more firmly inserted into the hole, improving the installation stability of the steel plate.

[0054] An electrode ring is fixed on the top of the clamping plate 203a and outside the plug rod 205a, and an electrode piece is also fixed to the end of the plug rod 205a. When the plug rod 205a moves outward from the jack T, the two come into contact to start the electric push rod 105d, and the steel plate can be pushed into the clamping plate 203a through it, and the steel plate in the clamping plate 203a can be pushed out to continue the rust removal operation on the subsequent steel plates. Its working principle is a prior art and will not be elaborated here.

[0055] During use, first place the steel plate to be processed in the clamping plate 203a, then place the subsequent steel plates to be processed in the placement box 104b. Then start the motor 204b, drive the threaded rod 204c to rotate through the motor 204b, drive the driving block 204a and the moving plate 202a to move upward. At this time, the gear 202d is in a position where it can mesh with the toothed plate 202e. During the upward movement of the moving plate 202a, the two mesh to drive the driving tube 202c and the clamping plate 203a to flip, and then continue to move upward to the topmost position. At this time, the inclined groove V on the trigger plate 202i drives the convex rod 202h and the pulling plate 202g to pull the driving tube 202c outward, and then use the laser rust remover 103 to perform rust removal operation on one surface of the steel plate.

[0056] After one surface is processed, drive the steel plate to move downward through the motor 204b. At this time, since the gear 202d is in a position where it cannot mesh with the toothed plate 202e, it can directly move downward to the bottommost position. And because the top plate 205b is in the downward position, the magnet 205d exerts a repulsive force on the plug rod 205a and the top plate 205b, so that the plug rod 205a can be more firmly inserted into the jack T. When the moving plate 202a moves to the bottommost position, the inclined groove V on the bottom trigger plate 202i drives the convex rod 202h and the pulling plate 202g to push the driving tube 202c inward, so that the gear 202d is in a position where it can mesh with the toothed plate 202e. At this time, when the steel plate continues to move upward, it will flip again to perform rust removal operation on the other surface.

[0057] After the rust removal operation on the other surface is completed as described above, the steel plate continues to move downward. Since the top plate 205b is in the upward position at this time, when the steel plate moves to the bottommost position, the magnet 205d exerts a repulsive force on the plug rod 205a and the top plate 205b, so that the plug rod 205a moves upward from the jack T to release the limit on the steel plate. At the same time, start the electric push rod 105d, drive the slide plate 105b to move to the right through the electric push rod 105d, and the push plate 105e drives the bottommost steel plate to move, push out the steel plate in the clamping plate 203a at this time, and push the new steel plate to be rust removed into the clamping plate 203a, and then continue the above operation. There is no need for manual flipping of the steel plate, which greatly improves the rust removal efficiency of the steel plate.
