Description

Technical Field

[0001] This application relates to the technical field of steel structure rust removal devices, and in particular to a shot blasting rust removal device for steel components. Background Technology

[0002] Steel structural components are a common type of building component. After being left for a long time, the surface of steel structural components will be corroded, resulting in rust. This rust will affect the subsequent processing and service life of the steel structural components, so rust removal equipment is needed to remove the rust.

[0003] The existing announcement number CN222430433U, entitled "A Shot Blasting and Rust Removal Device for Steel Components," includes a shot blasting machine frame. Bottom support columns are welded to the four lower corners of the frame. Workpiece moving rollers are movably connected to the upper part of the frame. A shot blasting assembly is fixed to the upper middle position of the frame, and a shot blasting recovery structure is installed at the lower middle position. The key feature is that a movable lifting drive is installed on the left side of the frame, and a workpiece shot blasting lifter is installed inside the movable lifting drive. The beneficial effects of this invention are: through the arrangement of the L-shaped bottom support, limiting sleeve, hollow frame, threaded drive rod, and servo motor, it is beneficial to move the steel structure workpiece upwards without the need for hoisting equipment, thereby improving the feeding efficiency of the shot blasting machine.

[0004] Regarding the aforementioned technologies, the inventors discovered that in the shot blasting rust removal of steel components, the shot blasting assembly of the shot blasting machine is vertically set. When the steel components are placed into the shot blasting assembly, there is a lack of a component to pull the steel structure. Manual lifting and pulling of the steel components to insert and pull them out of the shot blasting assembly is required, which cannot quickly place and remove the steel components from the shot blasting assembly, thus reducing the efficiency of rust removal. Utility Model Content

[0005] To overcome the problem that existing shot blasting machines lack components to pull the steel structure when placing steel components into the shot blasting assembly, requiring manual lifting and pulling of the steel components to insert and remove them from the assembly, which cannot quickly place and remove steel components and reduces rust removal efficiency, this application provides a shot blasting and rust removal device for steel components.

[0006] The shot blasting and rust removal device for steel components provided in this application adopts the following technical solution:

[0007] A shot blasting and rust removal device for steel components includes a shot blasting machine body, a screening component, and a fixing component. The bottom end of the shot blasting machine body is provided with a shot blasting port, and multiple rollers are horizontally rotatably connected to the vertical end face inside the shot blasting port of the shot blasting machine body. The multiple rollers on the vertical end face inside the shot blasting port of the shot blasting machine body are horizontally symmetrically arranged in the vertical direction. The screening component is connected to the bottom surface of the shot blasting machine body, and a fixing component is installed inside the shot blasting port of the shot blasting machine body. The fixing component includes a push-pull clamping frame, which is horizontally slidably inserted between the symmetrically arranged multiple rollers. The bottom of the symmetrical vertical end faces on both sides of the push-pull clamping frame is horizontally fixed with a support plate. The top surface of the symmetrical vertical end faces on both sides of the push-pull clamping frame is horizontally and vertically fixed with multiple threaded strips, and a clamping screw is assembled through the vertical thread on the threaded strips. The bottom of the outer wall of the shot blasting machine body is vertically fixed with multiple support frames.

[0008] By adopting the above technical solution, the steel components requiring shot blasting are placed in the push-pull clamping frame of the fixing component. The bottom of the steel component presses against the support plate. The clamping screw on the screw hole bar is rotated, and the bottom end of the clamping screw presses against the top surface of the steel component, thus ensuring the stability of the steel component during shot blasting. The fixing component holding the steel component is inserted into the shot blasting port of the shot blasting machine body. The outer horizontal plate of the push-pull clamping frame is inserted between multiple rollers on the inner wall of the push-pull clamping frame. Then, the shot blasting machine body is started to launch shot to impact the steel component and remove the rust on the steel component. Therefore, it is not necessary to manually lift and pull the steel component to insert and pull it out of the shot blasting assembly of the shot blasting machine. The steel component can be quickly placed and removed from the shot blasting assembly of the shot blasting machine, and the rust removal efficiency is increased.

[0009] Optionally, a hole seat is horizontally fixed on the outer vertical end face of the push-pull clamp frame, and an insert post is vertically slidably assembled through the hole seat.

[0010] By adopting the above technical solution, the fixed hole seat on the outer vertical end face of the push-pull clamp frame slides through the inserted post. The inserted post is used to position the fixing part inside the shot blasting port of the shot blasting machine body, ensuring that the steel structure on the fixing part remains stable during rust removal.

[0011] Optionally, a plug spring is vertically sleeved on the outside of the plug, and the two ends of the plug spring are fixed to the bottom end of the plug and the bottom surface of the hole seat, respectively.

[0012] By adopting the above technical solution, in order to ensure the vertical sliding of the insertion post on the hole seat and the stability of the insertion post tip inserted into the front hole plate of the shot blasting machine body, the deformation force of the insertion spring is used to drive the insertion post upward into the front hole plate of the shot blasting machine body, keeping the positioning and fixing parts inside the shot blasting machine body's blasting port, and ensuring that the steel structure on the fixing parts remains stable during rust removal.

[0013] Optionally, a perforated plate is horizontally fixed on the upper side of the shot blasting port of the shot blasting machine body, and the perforated plate is slidably inserted into the insertion post.

[0014] By adopting the above technical solution, the perforated plate and the insert column on the shot blasting machine body are slidably inserted to position the fixing component inside the shot blasting machine body, ensuring that the steel structure on the fixing component remains stable during rust removal.

[0015] Optionally, a cloth frame is fixed through the bottom surface of the shot blasting machine body, and multiple support springs are vertically fixed at the bottom of the vertical ends on both sides of the shot blasting machine body.

[0016] By adopting the above technical solution, the bottom of the shot blasting machine body is connected to a fixed cloth frame, and the cloth frame is used to connect the screening component. At the same time, multiple support springs on the shot blasting machine body are used to connect and assemble the screening component and the shot blasting machine body.

[0017] Optionally, the screening component includes a screening box with an opening on its top surface, and the opening end of the screening box is fixedly connected to the bottom surface of the fabric frame. The screening box contains a mesh, and one end of the mesh is inclined downwards and extends through the vertical end face of the screening box.

[0018] By adopting the above technical solution, the top surface of the screening box is opened, and the opening of the top surface of the screening box is connected to the cloth frame. The shot blasting and rust powder enter the interior of the screening box through the cloth frame. The shot blasting and rust powder are screened by the mesh. The rust powder falls down into the lower interior of the screening box through the mesh. Then the shot blasting is discharged from the side end face of the screening box under the guidance of the mesh.

[0019] Optionally, a drawer slide is provided through the bottom of one vertical end face of the filter box, and a drawer box is horizontally slidably assembled in the drawer slide.

[0020] By adopting the above technical solution, a drawer box is slidably assembled in the drawer slide at the bottom of the screening box. The drawer box is used to receive rust powder, and pulling the drawer box will empty the collected rust powder.

[0021] Optionally, the top of the screening box is fixedly connected to the bottom of multiple support springs, and a vibration motor is horizontally fixed to the outside of the screening box.

[0022] By adopting the above technical solution, in order to accelerate the screening effect of shot blasting and rust powder, the vibration motor is started to drive the screening box to vibrate, which causes multiple support springs to deform. The deformation force of the multiple support springs causes the screening box to vibrate, thus accelerating the screening of shot blasting and rust powder by the screen.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, the steel component requiring shot blasting is placed in the push-pull clamping frame of the fixing component, with the bottom of the steel component pressing against the support plate. Rotating the clamping screw on the screw hole strip causes the bottom end of the clamping screw to press against the top surface of the steel component, thus ensuring the stability of the steel component during shot blasting. The fixing component holding the steel component is inserted into the blasting port of the shot blasting machine body. The outer horizontal plate of the push-pull clamping frame is inserted between multiple rollers on the inner wall of the push-pull clamping frame. Then, the shot blasting machine body is started to launch shot to impact the steel component, removing the rust from the steel component. This eliminates the need for manual lifting and pulling of the steel component into and out of the shot blasting assembly, allowing for rapid placement and removal of the steel component within the shot blasting assembly, thus increasing the efficiency of the rust removal process.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a shot blasting and rust removal device for steel components. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A shot blasting and rust removal device for steel components includes a shot blasting machine body 1, a screening component 2, and a fixing component 3. The bottom end of the shot blasting machine body 1 is provided with a blasting port, and multiple rollers 11 are horizontally rotatably connected to the vertical end face inside the blasting port of the shot blasting machine body 1. The multiple rollers 11 on the vertical end face inside the blasting port of the shot blasting machine body 1 are horizontally symmetrically arranged along the vertical direction. The screening component 2 is connected to the bottom surface of the shot blasting machine body 1, and a fixing component 3 is installed inside the blasting port of the shot blasting machine body 1. The fixing component 3 includes a push-pull clamping frame 31, which is horizontally slidably inserted between multiple symmetrically arranged rollers 11. The bottom of the symmetrical vertical end faces on both sides of the push-pull clamping frame 31 is horizontally fixed with a support plate 32. Multiple screw hole strips 33 are horizontally and vertically fixed on the top surface of the symmetrical vertical end faces on both sides of the push-pull clamping frame 31. A clamping screw 34 is vertically threaded through the screw hole strips 33. Multiple support frames 14 are vertically fixed at the bottom of the outer wall of the shot blasting machine body 1.

[0032] By adopting the above technical solution, the steel components that need shot blasting are placed in the push-pull clamping frame 31 of the fixing part 3 during use. The bottom of the steel component is pressed against the support plate 32. The clamping screw 34 on the screw hole bar 33 is rotated, and the bottom end of the clamping screw 34 is pressed against the top surface of the steel component, thereby ensuring the stability of the steel component during shot blasting. The fixing part 3 holding the steel component is inserted into the blasting port of the shot blasting machine body 1. The outer horizontal plate of the push-pull clamping frame 31 is inserted between the multiple rollers 11 on the inner wall of the push-pull clamping frame 31. Then, the shot blasting machine body 1 is started to launch shot to impact the steel component and remove the rust on the steel component. Therefore, it is not necessary to manually lift and pull the steel component to insert and pull it out of the shot blasting machine assembly. The steel component can be quickly put and taken out of the shot blasting machine assembly, and the rust removal efficiency is increased.

[0033] Reference Figure 2 , Figure 3 and Figure 4A hole seat 35 is horizontally fixed on the outer vertical end face of the push-pull clamp frame 31, and a vertically sliding insertion post 36 is assembled through the hole seat 35. The insertion post 36 is slidably inserted through the fixed hole seat 35 on the outer vertical end face of the push-pull clamp frame 31. The insertion post 36 is used to position the fixing member 3 inside the shot blasting port of the shot blasting machine body 1, ensuring that the steel structure on the fixing member 3 remains stable during rust removal. A insertion spring 37 is vertically sleeved on the outside of the insertion post 36, and the two ends of the insertion spring 37 are respectively fixed to the bottom end of the insertion post 36 and the bottom surface of the hole seat 35. In order to ensure the stability of the insertion post 36 sliding vertically on the hole seat 35 and driving the top end of the insertion post 36 to insert into the front hole plate 15 of the shot blasting machine body 1, the deformation force of the insertion spring 37 is used to drive the insertion post 36 upward into the front hole plate 15 of the shot blasting machine body 1, keeping the fixing member 3 inside the shot blasting port of the shot blasting machine body 1, and ensuring that the steel structure on the fixing member 3 remains stable during rust removal. A perforated plate 15 is horizontally fixed on the upper side of the shot blasting port of the shot blasting machine body 1, and the perforated plate 15 is slidably inserted into the insert post 36. The perforated plate 15 and the insert post 36 on the shot blasting port of the shot blasting machine body 1 are slidably inserted into each other to position the fixing part 3 inside the shot blasting port of the shot blasting machine body 1, so as to ensure that the steel structure on the fixing part 3 remains stable during rust removal.

[0034] Reference Figure 3 and Figure 5A cloth frame 12 is fixedly fixed to the bottom surface of the shot blasting machine body 1, and multiple support springs 13 are vertically fixed to the bottom of the vertical ends on both sides of the shot blasting machine body 1. The cloth frame 12 is connected to the bottom end of the shot blasting machine body 1, and the screen component 2 is connected to it later. At the same time, the multiple support springs 13 on the shot blasting machine body 1 are used to connect and assemble the screen component 2 and the shot blasting machine body 1. The screen component 2 includes a screen box 21, which has an opening on its top surface. The opening end of the screen box 21 is fixedly connected to the bottom surface of the cloth frame 12. A mesh 22 is provided inside the screen box 21, and one end of the mesh 22 is inclined downward and extends through the vertical end of the screen box 21. The top surface of the screening box 21 has an opening that connects to the cloth frame 12. Shot blasting and rust powder enter the screening box 21 through the cloth frame 12. The shot blasting and rust powder are separated by the mesh 22. The rust powder falls downwards through the mesh 22 into the lower part of the screening box 21, while the shot blasting is discharged from the side end face of the screening box 21 under the guidance of the mesh 22. A drawer slide 23 is provided through the bottom of one vertical end face of the screening box 21, and a drawer box 24 is horizontally slidably assembled in the drawer slide 23. The drawer box 24, slidably assembled in the drawer slide 23 at the bottom of the screening box 21, is used to receive rust powder. Pulling the drawer box 24 will empty the collected rust powder. The top of the screening box 21 is fixedly connected to the bottom of multiple support springs 13, and a vibration motor 25 is horizontally fixed to the outside of the screening box 21. To accelerate the screening effect of shot blasting and rust powder, the vibration motor 25 is started to drive the screening box 21 to vibrate, which causes multiple support springs 13 to deform. The deformation force of the multiple support springs 13 causes the screening box 21 to vibrate, which accelerates the screening of shot blasting and rust powder by the screen 22.

[0035] The implementation principle of the shot blasting and rust removal device for steel components in this application embodiment is as follows: During use, the steel component requiring shot blasting and rust removal is placed in the push-pull clamping frame 31 of the fixing member 3. To ensure the vertical sliding of the insertion post 36 on the hole seat 35, and to maintain the stability of the insertion post 36's top end inserting into the front hole plate 15 of the shot blasting machine body 1, the deformation force of the insertion spring 37 drives the insertion post 36 upward into the front hole plate 15 of the shot blasting machine body 1. The positioning fixing member 3 remains inside the shot blasting port of the shot blasting machine body 1, with the bottom of the steel component pressing against the support plate 32. Rotating the clamping screw 34 on the screw hole strip 33 causes the bottom end of the clamping screw 34 to press against the top surface of the steel component, thus ensuring the stability of the steel component during shot blasting and rust removal. The fixing member 3 holding the steel component is inserted into the shot blasting port of the shot blasting machine body 1, and the push-pull clamping frame 31 is closed. The side cross plate is inserted between multiple rollers 11 on the inner wall of the push-pull clamp frame 31. Then, the shot blasting machine body 1 is started to launch shot to impact the steel components and remove the rust on the steel components. The top surface of the screening box 21 is set with an opening, which is connected to the cloth frame 12. The shot and rust powder enter the interior of the screening box 21 through the cloth frame 12. The shot and rust powder are screened by the mesh 22. The rust powder falls down into the lower interior of the screening box 21 through the mesh 22. Then, the shot is discharged from the side end face of the screening box 21 under the guidance of the mesh 22. In order to accelerate the screening effect of shot and rust powder, the vibration motor 25 is started to drive the screening box 21 to vibrate, causing multiple support springs 13 to deform. The deformation force of the multiple support springs 13 causes the screening box 21 to vibrate, accelerating the screening of shot and rust powder by the mesh 22.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
