Description

Technical Field

[0001] This utility model relates to the field of manhole cover production technology, and in particular to a shot blasting device for producing cast manhole covers. Background Technology

[0002] The core function of shot blasting for cast manhole covers is to thoroughly remove residual oxide scale, sand particles, and burrs from the casting process by impacting the surface with high-speed steel shot. At the same time, it forms a uniform compressive stress layer on the surface, significantly improving the fatigue strength and impact resistance of the manhole cover. More importantly, the clean surface with controllable roughness formed after shot blasting increases the adhesion of subsequent anti-corrosion coatings by more than 50%, directly extending the service life of the manhole cover by 3-5 years in harsh environments such as dampness and salt corrosion. This fundamentally avoids the failure of the load-bearing structure due to rust and ensures road traffic safety.

[0003] Chinese invention patent CN220660489U discloses a shot blasting machine capable of batch cleaning and removing dirt from manhole covers. This device can process and clean multiple manhole covers. However, this device cannot change the orientation of the manhole covers during the processing, which cannot guarantee the uniformity of the surface treatment and reduces the processing efficiency of the manhole covers.

Detailed Implementation

[0018] refer to Figures 1 to 5 The shot blasting device shown includes a treatment box 1, which is equipped with multiple sets of shot blasting heads 12 to treat the manhole covers 14. A lifting frame 11 is slidably arranged inside the treatment box 1. The lifting frame 11 drives multiple sets of manhole covers 14 into the treatment box 1. While treating the manhole covers 14, the lifting frame 11 can drive the multiple sets of manhole covers 14 to rotate, thereby improving the uniformity and efficiency of the treatment on the surface of the manhole covers 14.

[0019] A recovery box 2 is located on the side of the processing box 1, and the processing box 1 is connected to the recovery box 2. A strainer 10 is located at the lower end of the processing box 1. The strainer 10 is used to filter steel shot and debris. Debris enters the bottom of the processing box 1 for recovery through the strainer 10. Steel shot does not pass through the strainer 10 and accumulates on the surface of the strainer 10. A auger 9 is rotatably installed inside the processing box 1. The auger 9 is driven by a motor to rotate on the processing box 1. The auger 9 is located inside the processing box 1 and the recovery box 2, and the auger 9 is in contact with the strainer 10. When the auger 9 is driven to rotate, the auger... 9 moves the steel shot on the sluice plate 10, transferring the steel shot in the processing box 1 into the recovery box 2, completing the steel shot recovery. A baffle 3 is slidably installed on the processing box 1. The baffle 3 slides on the processing box 1 via a linear motor, and the baffle 3 closes the processing box 1. A lifting frame 11 is slidably installed at the upper end of the processing box 1. The lifting frame 11 slides inside the processing box 1 via a linear motor. Multiple sets of hooks 13 are rotatably installed at the lower end of the lifting frame 11. The manhole cover 14 is hung on the hooks 13. A gear 1 is coaxially installed on the hooks 13. 7. A rack 16 is slidably installed inside the lifting frame 11. A connecting block 19 is installed on the rack 16. The rack 16 meshes with a gear 17. A cylinder 18 is installed inside the lifting frame 11. The movable end of the cylinder 18 is connected to the connecting block 19. When the cylinder 18 is activated, the cylinder 18 drives the connecting block 19 to move. The connecting block 19 drives the gear 17 to rotate. The gear 17 drives the hook 13 to rotate. The hook 13 drives the manhole cover 14 to rotate, thus completing the deflection of the manhole cover 14 and improving the uniformity of the surface treatment of the manhole cover 14. The treatment box 1 is equipped with multiple sets of shot peening heads 12, each with a conveying pipe 15. Multiple sets of recovery pipes 8 are installed on the outside of the treatment box 1, and the recovery pipes 8 are connected to the treatment box 1. The shot peening heads 12 are connected to the recovery pipes 8 through the conveying pipes 15 to realize the conveying of steel shot. The side of the treatment box 1 is equipped with a mounting frame 4, and an adjusting plate 5 is slidably installed on the mounting frame 4. Two sets of mounting plates 6 are slidably installed on the adjusting plate 5. Each of the two sets of mounting plates 6 is rotatably equipped with a set of wiping heads 7, which wipe the surface of the manhole cover 14.

[0020] Working principle: In the initial state, the hoisting frame 11 is located outside the processing box 1. The manhole cover 14 is hung on the hook 13, and the hoisting frame 11 is driven to slide on the processing box 1. The hoisting frame 11 drives multiple sets of manhole covers 14 into the processing box 1. After the manhole cover 14 enters the processing box 1, the baffle 3 is driven to slide on the processing box 1, and the baffle 3 closes the processing box 1. When the manhole cover 14 reaches the working position, the shot peening head 12 is driven to work. The shot peening head 12 sprays steel shot onto the manhole cover 14 to complete the processing of the manhole cover 14. During the processing of the manhole cover 14, the cylinder 18 is activated. The cylinder 18 pushes the connecting block 19 to move. The connecting block 19 drives the rack 16 to slide on the hoisting frame 11. The rack 16 drives the gear 17 to rotate. The gear 17 drives the hook 13 to rotate. The hook 13 causes the manhole cover 14 to deflect, completing the adjustment of the angle of the manhole cover 14 and improving the processing efficiency of the manhole cover 14.

[0021] During the processing, steel shot and debris fall simultaneously onto the sluice plate 10. The sluice plate 10 filters the steel shot, and the debris falls into the bottom of the processing box 1, driving the auger 9 to rotate. The auger 9 moves the steel shot on the sluice plate 10 and transports the steel shot on the sluice plate 10 into the recovery box 2, completing the recovery of the steel shot. Then, the steel shot in the recovery box 2 is transported to the recovery pipe 8, and then transported to the shot blasting head 12 through the recovery pipe 8 and the conveying pipe 15, completing the rapid utilization of the steel shot.

[0022] After the manhole cover 14 is processed, the drive baffle 3 slides on the processing box 1, the baffle 3 releases the seal on the processing box 1, and the drive hoist 11 slides inside the processing box 1. The hoist 11 removes multiple sets of manhole covers 14. When it is necessary to clean the dust or residue on the surface of the manhole cover 14, the drive adjustment plate 5 slides on the mounting frame 4. The adjustment plate 5 drives the mounting plate 6 and the wiping head 7 to approach the manhole cover 14. The two sets of mounting plates 6 slide on the adjustment plate 5. When the two sets of mounting plates 6 approach the adjustment plate 5, they drive the two sets of wiping heads 7 to approach each other. After the two sets of wiping heads 7 are in contact with the manhole cover 14, the drive wiping head 7 rotates and cleans the manhole cover 14, thus completing the cleaning of the manhole cover 14.
