Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a shot blasting machine for processing guardrail panel components. Background Technology

[0002] Guardrail panels are a continuous structure made of corrugated steel panels spliced ​​together and supported by posts. They are primarily used for road traffic safety protection. Guardrail panels are exposed to the outdoor environment for extended periods, needing to withstand sunlight, rain, and salt spray corrosion; therefore, their surface must have excellent corrosion resistance. Traditional processes such as pickling and manual grinding are difficult to meet the needs of large-scale production and suffer from low efficiency, high pollution, and uneven treatment. Shot blasting machines use high-speed shot to impact the surface of the guardrail panels, quickly removing oxide scale, rust, and old coatings, creating a uniformly rough surface. This significantly improves coating adhesion and extends the life of the anti-corrosion coating.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-3As shown, it illustrates a shot blasting machine for processing guardrail components in one embodiment of the present invention, including a transmission base 1, a shot blasting machine body 4 fixed on the top of the transmission base 1, an adjustment component 2 installed inside the shot blasting machine body 4, and a flipping component 3 installed on the side of the shot blasting machine body 4. The adjusting assembly 2 includes a shot storage box 21. A shot blaster 22 is sealed to the bottom of the shot storage box 21. A support plate 23 is fixed to the bottom of the shot blaster 22. A first motor 24 is fixed to the side of the support plate 23. A directional sleeve 25 is fixed to the output end of the first motor 24. A shot outlet 26 is fixed to the bottom of the directional sleeve 25. Both sides of the directional sleeve 25 have inlets, and one inlet communicates with the shot outlet 26. The shot blaster 22 is equipped with an independent power supply. The shot blaster 22 consists of a motor, a rotating rod, and blades, and can perform complete shot conveying. A negative pressure suction pump is installed inside the shot storage box 21, which can suck the shot conveyed from the conveying shell 210 into the shot storage box 21 for storage.

[0024] In some examples, the bottom of the shot blaster 22 is provided with a groove 27 near the shot outlet 26. The groove 27 is arc-shaped, which facilitates rotation adjustment in the groove 27 when the shot outlet 26 is adjusted in angle.

[0025] In some examples, laser sensors 28 are fixed on both sides of the shot blasting machine body 4. The laser sensors 28 are of the FD-L150T type and are used to detect the width of the guardrail. The PLC then controls other components to adjust the guardrail accordingly.

[0026] In some examples, the side of the shot storage box 21 is sealed with a conveying pipe 29, and the other end of the conveying pipe 29 is sealed with a conveying housing 210. The bottom of the conveying housing 210 is fixed with a connecting box 213, and a collection box 215 is installed at the bottom of the connecting box 213. The side of the connecting box 213 near the conveying base 1 is sealed with a recovery pipe 216, and the other end of the recovery pipe 216 is fixed with an inclined plate 217. The inclined plate 217 facilitates the recovery of used shot and prevents excessive accumulation in the conveying base 1, which could affect the conveying roller.

[0027] In some examples, an electric motor 211 is fixed to the top inside the conveying housing 210, and a spiral conveying rod 212 is fixed to the output end of the electric motor 211. The spiral conveying rod 212 is rotatably connected inside the connecting box 213, and a filter screen 214 is fixed to the bottom of the connecting box 213. The spiral conveying rod 212 is used to convey complete projectiles to the shot storage box 21. The aperture size of the filter screen 214 is smaller than the diameter of the complete projectile, and it is used to screen incomplete projectiles. The inclined plate 217 is fixed inside the transmission base 1, and a stop is fixed on the outside of the inclined plate 217. The stop prevents the projectile from falling into the inclined plate 217 and being ejected to the outside of the inclined plate 217 by gravity or elastic force.

[0028] For example, such as Figure 3 As shown, when surface cleaning of the guardrail panel is required, firstly, when the guardrail panel is conveyed to the shot blasting machine body 4 via the transmission base 1, the width of the guardrail panel is detected by the laser sensor 28, and the detection data is transmitted to the PLC. The PLC then controls the first motor 24 to drive the directional sleeve 25 to rotate, thereby causing the directional sleeve 25 to adjust the angle of the shot outlet 26 within the groove 27. This ensures that the exit of the shot outlet 26 matches the width of the guardrail panel, allowing the shot to be propelled from the shot outlet 26 by the shot blaster 22. 6. The guardrail surface is sprayed and cleaned. The cleaned shot falls into the inclined plate 217 and rolls into the connecting box 213 by gravity through the recovery pipe 216. Damaged shot falls into the collection box 215 through the filter screen 214 at the bottom of the connecting box 213. Intact shot is driven by the electric motor 211 controlled by PLC to rotate the screw conveyor 212, so that the screw conveyor 212 transports the shot back to the shot storage box 21, so that the shot can be reused to reduce the consumption of shot.

[0029] like Figures 4-5 As shown, this invention illustrates a shot blasting machine for processing guardrail components in another embodiment of the present invention. The flipping assembly 3 includes a lifting groove 31, with a hydraulic rod 32 fixed at the top of the lifting groove 31 and a connecting block 33 fixed at the bottom of the hydraulic rod 32. A second motor 34 is fixed to the side of the connecting block 33, and a rotating shaft 35 is fixed to the output end of the second motor 34. An electric telescopic rod 36 is fixed to the other end of the rotating shaft 35, and a pneumatic gripper 37 is rotatably connected to the other end of the electric telescopic rod 36. Both the pneumatic gripper 37 and the electric telescopic rod 36 are equipped with independent power supplies, and both are controlled by a PLC. The hydraulic rod 32 is equipped with a complete hydraulic transmission system, the specific structure of which includes a hydraulic pump, a hydraulic cylinder, a prime mover, a hydraulic motor, and a hydraulic valve, so that the hydraulic rod 32 can maintain a stable working state during transmission.

[0030] In some examples, pneumatic grippers 37 are provided on both sides of the transmission base 1, which allows for stable clamping of the guardrail.

[0031] For example, such as Figure 5As shown, when the guardrail enters the shot blasting machine body 4 through the transfer base 1, the surface of the guardrail is first cleaned by using the adjustment component 2. Then, the hydraulic rod 32 controlled by the PLC pushes the pneumatic gripper 37 to move to the side of the guardrail. Then, the electric telescopic rod 36 controlled by the PLC drives the pneumatic gripper 37 to approach the guardrail and clamp the guardrail. Then, the hydraulic rod 32 drives the pneumatic gripper 37 to move upward, so that the guardrail is separated from the top surface of the transfer base 1. Then, the second motor 34 controlled by the PLC drives the rotating shaft 35 to rotate, so that the guardrail is flipped over. The reverse side of the guardrail is then cleaned again by the adjustment component 2, so that the guardrail can be thoroughly cleaned and blind spots in the cleaning of the guardrail are prevented.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
