Description

Technical Field

[0001] This utility model relates to the field of steel bar technology, and in particular to a steel bar rust removal device. Background Technology

[0002] Steel bars refer to steel used in reinforced concrete and prestressed reinforced concrete, and are the core load-bearing materials in construction projects. Their cross-section is mostly circular, but some special specifications use a square design with rounded corners to adapt to the mechanical requirements of different construction scenarios.

[0003] In the building materials trade and logistics process, steel bars are usually stored centrally in warehouses. Due to factors such as humidity and dust in the warehouse environment, a loose layer of surface rust easily forms on the surface of the steel bars. If steel bars with surface rust are directly cut, bent, or processed and then used in the project, it may not only affect the bond strength between the steel bars and concrete, but also weaken their mechanical properties, thus posing a potential threat to the overall safety and durability of the building structure. Utility Model Content

[0004] To solve the above problems, this utility model provides a steel bar rust removal device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel bar rust removal device, including a frame and a workbench set on the frame, a hollow box set on the workbench, rotating holes opened on opposite sides of the hollow box, a rotating tube rotatably arranged in the two rotating holes, a driving assembly for driving the rotating tube to rotate on the hollow box, a plurality of brush plates arranged circumferentially at intervals on the inner wall of the rotating tube, a strip-shaped hole opened on the tube body between two adjacent brush plates, an air pump set at the lower part of the hollow box, and a collection assembly set inside the hollow box.

[0006] By adopting the above technical solution, a rotating tube, a brush plate, and a collection component are installed. The reinforcing steel passes through the rotating tube, and the drive component drives the rotating tube and the brush plate to rotate synchronously. The bristles on the brush plate can remove the floating rust and dust from the surface of the reinforcing steel, preventing the floating rust from affecting the bond strength between the reinforcing steel and the concrete, ensuring the mechanical properties of the reinforcing steel, and thus ensuring the overall safety of the building structure. At the same time, the operation of the air pump creates a negative pressure inside the hollow box. Outside air enters the hollow box through the slotted holes on the rotating tube, promptly sucking in the brushed-off floating rust and dust, which is then collected by the collection component. This prevents the floating rust and dust from spreading and polluting the environment, and also prevents them from adhering to subsequent equipment or reinforcing steel, thus affecting the quality of the reinforcing steel.

[0007] Furthermore, a square opening is provided on the workbench, a base plate is provided on the frame, the hollow box is placed in the square opening and fixedly connected to the workbench, the bottom of the hollow box is connected to the base plate, the bottom of the air pump is connected to the base plate, and the air extraction pipe is connected to the hollow box.

[0008] Furthermore, the hollow box is hinged to a door on the box body located below the workbench. The collection component includes an installation frame and support bars on the inner walls of opposite sides of the hollow box for supporting the installation frame. A collection net is provided inside the installation frame, and a rubber ring is provided at the bottom of the installation frame.

[0009] By adopting the above technical solution, the installation frame is supported in the hollow box by the support strip, and the collection net inside the installation frame can effectively intercept and collect the sucked-in floating rust and dust.

[0010] Furthermore, the drive assembly includes a mounting base disposed on the hollow box, a drive motor horizontally disposed on the mounting base, an active synchronous pulley fixedly sleeved on the output shaft of the drive motor, one end of the rotating tube located outside the hollow box and fixedly sleeved with a driven synchronous pulley, and the active synchronous pulley and the driven synchronous pulley connected by a synchronous belt.

[0011] By adopting the above technical solution, a drive motor, an active synchronous pulley, and a driven synchronous pulley are set up. The drive motor drives the active synchronous pulley, which in turn drives the driven synchronous pulley and the rotating tube to rotate through the synchronous belt transmission.

[0012] Furthermore, a horizontal shaft is provided outside the hollow box for horizontal rotation, and a tensioning wheel is sleeved on the horizontal shaft, with the tensioning wheel in contact with the outer side of the timing belt.

[0013] Furthermore, two C-shaped plates are vertically spaced on one side of the hollow box, and two straightening rollers are vertically rotatably arranged between the two C-shaped plates.

[0014] By adopting the above technical solution, C-shaped plates and straightening rollers are set up. Before the steel bars enter the rotating tube, the straightening rollers can play a preliminary straightening role on the steel bars, so that the position of the steel bars is relatively stable and will not collide with the rotating tube.

[0015] Furthermore, the two straightening rollers are arranged symmetrically along the center line of the rotating tube.

[0016] Furthermore, two connecting rods are provided on the side of the C-shaped plate away from the hollow box, and a horn tube is provided at one end of all four connecting rods.

[0017] By adopting the above technical solution, a connecting rod and a horn tube are set up. The horn tube guides the incoming steel bars, which can guide the steel bars smoothly and accurately into the space between the two straightening rollers and into the subsequent rotating tube, reducing the deviation and jamming phenomenon during steel bar feeding and improving the smoothness and stability of equipment operation.

[0018] In summary, this utility model has the following beneficial effects: In this application, a rotating tube, a brush plate, and a collection component are provided. The reinforcing bar passes through the rotating tube, and the driving component drives the rotating tube and the brush plate to rotate synchronously. The bristles on the brush plate can remove surface rust and dust from the reinforcing bar, preventing the rust from affecting the bond between the reinforcing bar and concrete, ensuring the mechanical properties of the reinforcing bar, and thus ensuring the overall safety of the building structure. Simultaneously, the operation of the air pump creates negative pressure inside the hollow box. Outside air enters the hollow box through the slotted holes on the rotating tube, promptly drawing the brushed-off rust and dust into the hollow box and collecting it with the collection component. This prevents the rust and dust from spreading and polluting the environment, and also prevents them from adhering to subsequent equipment or the reinforcing bar, affecting its quality.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] like Figure 1-6As shown in the figure, this application discloses a rebar rust removal device, including a frame 10 and a workbench 11. The workbench 11 is mounted on the frame 10, and a hollow box 20 is mounted on the workbench 11. Rotating holes are opened on opposite sides of the hollow box 20, and the two rotating holes are arranged concentrically. A rotating tube 30 is rotatably mounted in both rotating holes. A driving assembly 40 is mounted on the hollow box 20 to drive the rotating tube 30 to rotate. A plurality of brush plates 31 are circumferentially spaced on the inner wall of the rotating tube 30. The brush plates 31 are steel wire brush plates 31, which are composed of a base plate and a plurality of steel wire bristles mounted on the base plate. After passing through the rotating tube 30, the reinforcing bars pass through subsequent processing equipment, such as a reinforcing bar straightening machine or a fully automatic CNC reinforcing bar bending machine. During processing, the reinforcing bars are continuously pulled and moved. The drive assembly 40 drives the rotating tube 30 and the brush plate 31 to rotate synchronously. The bristles on the brush plate 31 can remove the surface rust and dust of the reinforcing bars, preventing the rust from affecting the bond between the reinforcing bars and concrete, ensuring the mechanical properties of the reinforcing bars, and thus ensuring the overall safety of the building structure. The rotating tube 30 has a strip-shaped hole 32 on its body between two adjacent brush plates 31. An air pump 21 is installed at the bottom of the hollow box 20. The operation of the air pump 21 creates a negative pressure inside the hollow box 20, allowing outside air to enter the hollow box 20 through the strip-shaped hole 32 on the rotating tube 30, and promptly sucking in the brushed-off rust and dust. A collection assembly 50 is installed inside the hollow box 20 to collect the rust and dust sucked in. To prevent rust and dust from spreading and polluting the environment, and to prevent them from adhering to subsequent equipment or reinforcing bars and affecting the quality of the reinforcing bars.

[0023] Specifically, a square opening is provided on the workbench 11, and a base plate 12 is provided on the frame 10. The hollow box 20 is placed inside the square opening and fixedly connected to the workbench 11. The bottom of the hollow box 20 is connected to the base plate 12. Placing the hollow box 20 inside the square opening of the workbench 11 and fixing it to the workbench 11 and the base plate 12 ensures that the hollow box 20 is installed stably. The bottom of the air pump 21 is connected to the base plate 12, and the air extraction pipe is connected to the bottom of the hollow box 20, with the internal space of the air extraction pipe communicating with the internal space of the hollow box 20. The air pump 21 is connected to the base plate 12 and communicates with the hollow box 20 through the air extraction pipe, ensuring that the air pump 21 can stably extract air from the hollow box 20 when it is working, ensuring the formation of a negative pressure environment inside the hollow box 20, improving the extraction and collection effect of floating rust and dust, and facilitating the overall installation and maintenance of the equipment.

[0024] In setup, the drive assembly 40 includes a mounting base 41 mounted on the hollow box 20. A drive motor 42 is horizontally mounted on the mounting base 41. A drive synchronous pulley 43 is fixedly sleeved on the output shaft of the drive motor 42. One end of the rotating tube 30 is located outside the hollow box 20 and is fixedly sleeved with a driven synchronous pulley 44. The drive synchronous pulley 43 and the driven synchronous pulley 44 are connected by a synchronous belt 45. The drive motor 42 drives the drive synchronous pulley 43, which in turn drives the driven synchronous pulley 44 and the rotating tube 30 to rotate via the synchronous belt 45. This ensures that the rotating tube 30 and the brush plate 31 rotate at a stable speed, ensuring a uniform and consistent brushing effect on the surface rust and dust of the reinforcing bars. It also facilitates the control of the rotation speed of the rotating tube 30 to meet the cleaning needs of reinforcing bars of different specifications. A horizontal shaft 60 is horizontally rotatably mounted outside the hollow box 20. A tensioning wheel 61 is sleeved on the horizontal shaft 60, and the tensioning wheel 61 contacts the outer surface of the synchronous belt 45. It can tighten the timing belt 45, prevent the timing belt 45 from loosening, ensure the transmission efficiency and stability between the driving timing pulley 43 and the driven timing pulley 44, and avoid the unstable speed of the rotating tube 30 due to the loosening of the timing belt 45, which would affect the brushing effect.

[0025] In the specific setup, to ensure that the reinforcing bars do not collide with the rotating tube 30 before entering it, two C-shaped plates 70 are vertically spaced in the hollow box 20, and two straightening rollers 71 are vertically rotated between the two C-shaped plates 70. The two straightening rollers 71 are symmetrically arranged along the center line of the rotating tube 30. Before the reinforcing bars enter the rotating tube 30, the straightening rollers 71 can play a preliminary straightening role, making the position of the reinforcing bars relatively stable and preventing them from colliding with the rotating tube 30. Two connecting rods 72 are set on the side of the C-shaped plates 70 away from the hollow box 20, and a horn tube 73 is set at the end of the four connecting rods 72 away from the hollow box 20. The small opening of the horn tube 73 is close to the hollow box 20, and the large opening is away from the hollow box 20. The horn tube 73 guides the entering reinforcing bars, guiding them smoothly and accurately into the space between the two straightening rollers 71 and into the subsequent rotating tube 30, reducing deviation and jamming during reinforcing bar feeding, and improving the smoothness and stability of equipment operation.

[0026] The collection component 50 includes a mounting frame 52 and support bars 51 on the inner walls of opposite sides of the hollow box 20 to support the mounting frame 52. A collection net 53 is installed inside the mounting frame 52, which is supported within the hollow box 20 by the support bars 51. The collection net 53 inside the mounting frame 52 effectively intercepts and collects sucked-in rust and dust. A door 22 is hinged to the hollow box 20 located below the workbench 11, allowing operators to easily open the hollow box 20 and replace or clean the collection net 53. A rubber ring 54 is installed at the bottom of the mounting frame 52. When the door 22 is closed, the edges of the rubber ring 54 contact the inner walls of the hollow box 20 and the inner side of the door 22, respectively. This enhances the seal between the mounting frame 52 and the hollow box 20, preventing rust and dust from leaking out, improving collection efficiency, and simplifying the cleaning or replacement of the collection net 53.

[0027] The working principle of the rebar rust removal device in this embodiment is as follows: The rebar is first guided by the trumpet tube 73 and enters the straightening roller 71 for preliminary straightening, ensuring that it enters the rotating tube 30 in a stable posture and will not collide with the rotating tube 30. After passing through the rotating tube 30, it passes through the subsequent processing equipment. During the processing of the subsequent processing equipment, the rebar is continuously pulled to make it move. At the same time, the drive motor 42 drives the active synchronous pulley 43, which is driven by the synchronous belt 45 and the driven synchronous pulley 44 to rotate the rotating tube 30. The steel wire brushes on the inner wall of the rotating tube 30 rotate synchronously to brush away the surface rust and dust of the rebar. At the same time, the air pump 21 works to create a negative pressure in the hollow box 20. Outside air enters through the strip hole 32 on the rotating tube 30 and sucks the brushed-off surface rust and dust into the hollow box 20, where it is intercepted and collected by the collection net 53 in the mounting frame 52 supported by the support bar 51.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
