When the steel structure passes by, the surface of the steel structure facing the shot outlet of the shot blasting machine is hit by the shot, and the rust on its surface is knocked off by the shot, achieving rust removal. Generally, each shot blasting machine is at a position with a different central angle, so that each surface of the steel structure can be rust-removed.

The vibrating plate assembly B shakes the screen plate to promote the forward movement of the shot and the iron filings. The shot falling into the shot collecting tank is conveyed to the shot distributing component under the action of the conveying device B, and then is dispersed into each shot storage box by the shot distributing component, so that the shot storage box is continuously replenished with shot, prolonging the operable time of the shot blasting machine.

Specific embodiments
[0027] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Embodiment:
[0029] As Figures 1 to 6As shown in the figure, this embodiment provides a shot blasting and rust removal device for a steel structure grid, including a shot blasting chamber 1. Symmetric openings 2 are respectively provided at the left and right ends of the shot blasting chamber 1. A conveying device A 3 is arranged in the shot blasting chamber 1 and passes through the two openings 2 in the left-right direction. A number of pairs of fixing plates 4 are evenly arranged above the conveying device A 3 along the material conveying direction of the conveying device A 3 in the shot blasting chamber 1. The shape of the fixing plate 4 is an upper semi-circular ring. The centers of the fixing plates 4 are on the same straight line in the left-right direction and this straight line coincides with the midline of the upper surface of the conveying device A 3. A moving component 5 that can move along the fixing plate 4 is arranged on each pair of fixing plates 4. A shot blasting machine is arranged on the moving component 5. When the shot blasting machine moves with the moving component 5, its shot blasting direction always points to the straight line where the centers of the fixing plates 4 are located. A shot storage box 7 corresponding to the shot blasting machine 6 is arranged at the top of the shot blasting chamber 1. The outlet of the shot storage box 7 is communicated with the inlet of the shot blasting machine 6 through a telescopic pipe 44. A material guiding plate 8 is arranged below the conveying device A 3 in the shot blasting chamber 1. The cross-sectional shape of the top of the material guiding plate 8 is an isosceles triangle. There are gaps between the left and right ends of the material guiding plate 8 and the inner wall of the shot blasting chamber 1. Sieve plates 9 that incline downward toward the middle are respectively arranged below the left and right ends of the material guiding plate 8 in the shot blasting chamber 1. A rust collection tank 10 is arranged below the sieve holes of the sieve plate 9 at the bottom of the shot blasting chamber 1, and a shot collection tank 11 is arranged below the lower end of the sieve plate 9. A vibration plate assembly A 12 is connected to the bottom of the material guiding plate 8, and a vibration plate assembly B 13 is connected to the bottom of the sieve plate 9. A conveying device B 14 is arranged behind the shot blasting chamber 1. The inlet of the conveying device B 14 is communicated with the bottom of the rear inner wall of the shot collection tank 11. The outlet of the conveying device B 14 is communicated with the inlet of the shot distribution component 45. Each outlet of the shot distribution component 45 is connected to the inlet of the shot storage box 7 one by one.
[0030] By using the fixed plate 4 and the moving component 5 in combination, the position of the shot blasting machine 6 on the moving component 5 is changed, so that the surfaces of the steel structure in different orientations can be fully subjected to shot blasting and rust removal treatment, improving the treatment effect; the steel structure moves from left to right under the action of the conveying device A3, and the started shot blasting machine 6 shoots shot at the upper surface of the conveying device A3. When the steel structure passes by, the surface of the steel structure facing the shot outlet of the shot blasting machine 6 is struck by the shot, and the rust on its surface is knocked off by the shot, achieving rust removal. Generally, each shot blasting machine 6 is located at different central angles so that each surface of the steel structure can be subjected to rust removal treatment. By using the material guiding plate 8 and the screen plate 9 in combination, the shot and the rust are separated from each other, facilitating the cleaning of iron filings and the recycling of shot. The vibrating plate assembly A12 and the vibrating plate assembly B13 are used to reduce the probability of iron filings and shot staying on the material guiding plate 8 and the screen plate 9. By using the conveying device B14 and the shot distributing component 45 in combination, the shot shot by the shot blasting machine 6 is helped to return to the shot storage box 7 for reuse, reducing the frequency of replenishing the shot in the shot storage box 7 and prolonging the running time of the device; the screen plate 9 is used to separate the shot and the iron filings, and the material guiding plate 8 is used to guide the iron filings and shot at different landing points to a position convenient for the screen plate 9 to screen. When the shot shot and the knocked-off iron filings leak through the conveying device and fall onto the material guiding plate 8, the shot and the iron filings slide down along the material guiding plate 8 to both sides and fall through the gaps between the left and right ends of the material guiding plate 8 and the inner wall of the shot blasting chamber 1 to the lower screen plate 9. The vibrating plate assembly A12 promotes the forward movement of the shot and the iron filings by vibrating the material guiding plate 8. The shot and the iron filings falling on the screen plate 9 slide down from both sides to the middle along the screen plate 9. When passing through the sieve holes on the screen plate 9, the small-sized iron filings leak through the sieve holes and fall into the lower rust collection tank 10, and the large-sized shot rolls over the sieve hole part and finally falls into the middle shot collection tank 11. The vibrating plate assembly B13 promotes the forward movement of the shot and the iron filings by vibrating the screen plate 9. The shot falling into the shot collection tank 11 is conveyed to the shot distributing component 45 under the action of the conveying device B14, and then is dispersed into each shot storage box 7 by the shot distributing component 45, so that the shot storage box 7 is continuously replenished with shot, and the operable time of the shot blasting machine 6 is prolonged.
[0031] Further, the vibration plate assembly A12 includes a rotating rod A15, a long rod A16, an arc-shaped groove A17, a motor A18, a spring telescopic rod A19, and a cross plate 20. Inside the shot blasting chamber 1, a rotating rod A15 is rotatably connected below the feeding plate 8. The rotating rod A15 extends in the front-rear direction. A motor A18 with a driving rod coaxially connected to the rotating shaft of the rotating rod A15 is provided on the front surface of the shot blasting chamber 1. Along the circumference of the middle part of the rotating rod A15, long rods A16 are evenly arranged in the radial direction. An arc-shaped groove A17 located above the long rods A16 is provided at the bottom of the feeding plate 8. A cross plate 20 is provided inside the shot blasting chamber 1 below the feeding plate 8. A vertically arranged spring telescopic rod A19 is connected between the cross plate 20 and the bottom of the feeding plate 8. When the long rod A16 inserted into the arc-shaped groove A17 rotates to the highest position, the spring telescopic rod A19 is stretched to the maximum length. When the arc-shaped groove A17 is not in contact with the long rod A16, the spring telescopic rod A19 contracts to the minimum length.
[0032] The motor A18 provides the power required for the rotation of the rotating rod A15. When the rotating rod A15 rotates, the long rod A16 rotates accordingly. During the process of the long rod A16 turning into the arc-shaped groove A17 and rotating to the highest position, the arc-shaped groove A17 and the feeding plate 8 connected to the arc-shaped groove A17 are lifted by the long rod A16, and the spring telescopic rod A19 undergoes elastic deformation due to stretching. During the process of the long rod A16 rotating past the highest position and turning out of the arc-shaped groove A17, the feeding plate 8 returns to its original position under the action of its own weight and the restored spring telescopic rod A19. The rotating rotating rod A15 causes the long rod A16 to repeatedly lift and lower the arc-shaped groove A17, achieving the effect of vibrating the feeding plate 8. In order to prevent the shot and iron filings on the feeding plate 8 from leaking past the feeding plate 8 from the front and rear sides, the front edge and the rear edge of the feeding plate 8 generally lean against the front and rear inner walls of the shot blasting chamber 1. The spring telescopic rod A19 restricts the vibration direction of the feeding plate 8 to the vertical direction, reducing the wear of the front edge and the rear edge of the feeding plate 8 on the inner wall of the shot blasting chamber 1. The cross plate 20 serves as an installation surface for the spring telescopic rod A19.
[0033] Furthermore, the vibration plate assembly B13 includes a rotating rod B21, a long rod B22, an arc groove B23, a motor B24, a spring telescopic rod B25 and a fixed column 26. The inner wall of the shot blasting chamber 1 is provided with a rotating seat 27 near the upper end of the screen plate 9. The upper end of the screen plate 9 is rotatably connected to the rotating seat 27. The shot blasting chamber 1 is rotatably connected with a rotating rod B21 below the upper end of the screen plate 9. The rotating rod B21 is arranged along the front and rear directions. A motor B24 is provided on the front side of the shot blasting chamber 1. The middle of the rotating rod B21 is connected to the rotating shaft of the rotating rod B21. A long rod B22 is evenly arranged along the circumferential direction along the radial direction, and an arc groove B23 is arranged above the long rod B22 at the bottom of the screen plate 9. A fixed column 26 is arranged below the lower end of the screen plate 9 in the shot blasting chamber 1, and a spring telescopic rod B25 is arranged on the fixed column 26. The top end of the spring telescopic rod B25 is movably connected with the lower end of the screen plate 9. When the long rod B22 that is pressed into the arc groove B23 is rotated to the highest point, the spring telescopic rod B25 is stretched to the maximum length. When the arc groove B23 is not in contact with the long rod B22, the spring telescopic rod B25 is contracted to the minimum length.
[0034] The motor B24 provides the power required for the rotation of the rotating rod B21. When the rotating rod B21 rotates, the long rod B22 rotates accordingly. When the long rod B22 rotates into the arc groove B23 and rotates to the highest point, the arc groove B23 and the screen plate 9 connected to the arc groove B23 are lifted up by the long rod B22 and rotate upward. The spring telescopic rod B25 is elastically deformed due to stretching. When the long rod B22 rotates from the highest point to the arc groove B23, the screen plate 9 moves upward under the action of its own weight and the restoring spring telescopic rod B25. Rotate back to its original position, and the rotating rotating rod B21 causes the long rod B22 to repeatedly lift and lower the arc groove B23, thereby achieving the effect of shaking the screen plate 9. In order to prevent the shot blasting and iron filings on the screen plate 9 from leaking through the screen plate 9 from the front and rear sides, the front and rear edges of the screen plate 9 generally lean against the front and rear inner walls of the shot blasting cabin 1. The spring telescopic rod B25 limits the shaking direction of the screen plate 9 to the vertical direction, thereby reducing the wear of the front and rear edges of the screen plate 9 on the inner wall of the shot blasting cabin 1, and the fixed column 26 provides a mounting surface for the spring telescopic rod B25. Specifically, a through opening along the left-right direction is provided at the lower end of the screen plate 9, and an I-shaped block is provided at the top of the spring telescopic rod B25. The width of the middle part of the block is equivalent to the width of the through opening, and the widths of the upper and lower parts of the block are greater than the width of the through opening. The middle part of the block is placed in the through opening and the front and rear outer walls of the middle part of the block abut against the inner wall of the through opening. The combination of the block and the through opening realizes the active connection between the spring telescopic rod B25 and the lower end of the screen plate 9, and does not interfere with the rotation of the screen plate 9 while limiting the shaking direction of the screen plate 9.
[0035] Further, the moving component 5 includes a moving plate 28, a vertical plate 29, a motor C30, a gear 31, and a chute 32. A moving plate 28 is provided between each pair of fixed plates 4. A shot blasting machine 6 is provided at the bottom of the moving plate 28. A through hole 35 for the telescopic pipe 44 to pass through is provided on the moving plate 28. A pair of symmetrically arranged vertical plates 29 are provided at the top of the moving plate 28. A motor C30 is provided at the upper end of the vertical plate 29, and a chute 32 is provided at the lower end of the vertical plate 29. A gear 31 is provided on the driving rod of the motor C30. A rack 33 is provided along an arc at the top of the fixed plate 4. The rack 33 meshes with the gear 31. A slide rail 34 is provided along an arc at the bottom of the fixed plate 4. The slide rail 34 is slidably connected to the chute 32.
[0036] By using the chute 32 and the slide rail 34 in combination, the movement track of the moving plate 28 is restricted. Through the motor C30, the gear 31, and the rack 33, the power required for the movement of the moving plate 28 is given. After the motor C30 is started, it drives the gear 31 to rotate. The rotating gear 31 moves along the meshing rack 33, thereby driving the moving plate 28 indirectly connected to the gear 31 to move together. By changing the position of the moving plate 28 on the fixed plate 4, the position of the shot blasting machine 6 installed at the bottom of the moving plate 28 is changed, achieving the effect of adjusting the shot blasting direction.
[0037] Further, the shot distributing component 45 includes a shot distributing plate 36 and a connecting pipe 37. A number of radially distributed channels 38 are provided in the shot distributing plate 36. The connecting pipe 37 is composed of a main box 39 and a number of branch pipes 40 connected to the main box 39. The outlet of the conveying device B14 is communicated with the port at the converging part of the channels 38 of the shot distributing plate 36. The port at the diverging part of the channels 38 of the shot distributing plate 36 is communicated with the upper end port of the main box 39. The channels 38 are evenly distributed to each branch pipe 40. The parabola of the channel 38 extends into the upper end port of the corresponding branch pipe 40. The lower end port of the branch pipe 40 is communicated with the inlet of the corresponding shot storage box 7.
[0038] The shot is guided by the channels 38 on the shot distributing plate 36, and the shot sent into the shot distributing plate 36 by the conveying device B14 is evenly thrown into each branch pipe 40. The shot enters the shot storage box 7 communicated with the branch pipe 40 along the branch pipe 40, avoiding the problem that the shot blasting process ends prematurely due to a small amount of shot recovered by some shot storage boxes 7.
[0039] Further, the shape of the bottom of the shot collecting groove 11 is an inclined plane that slopes downward from front to back. The inclined plane at the bottom of the shot collecting groove 11 can help the shot enter the conveying device B14 more easily.
[0040] Further, a supplementary shot blasting inlet 41 aligned with the bottom of the shot collecting tank 11 and a waste removing opening 42 aligned with the bottom of the rust collecting tank 10 are provided on the front of the shot blasting chamber 1. Sealing doors 43 are respectively hinged on the supplementary shot blasting inlet 41 and the waste removing opening 42. Through the supplementary shot blasting inlet 41 and the waste removing opening 42, it is convenient for the staff to supplement new shot blasting into the shot collecting tank 11 and clean the accumulated rust, deformed and broken damaged shot blasting in the rust collecting tank 10 afterwards. When operating, the corresponding sealing door 43 can be lifted up.
[0041] Further, the number of shot blasting machines 6 is 3.
[0042] Further, the conveying device A3 is a roller conveyor.
[0043] Further, the conveying device B14 is a screw feeder.
[0044] The working principle and usage process of the present utility model are as follows:
[0045] Before rust removal treatment, according to the rust removal requirements of the steel structure, adjust the positions of the shot blasting machines 6 so that each surface to be rust removed can be covered by shot blasting. After the adjustment of the shot blasting machines 6 is completed, the staff place the steel structure to be rust removed at the left end of the conveying device A3, and start the conveying device A3, the conveying device B14, the shot blasting machines 6, the motor A18 and the motor B24. The steel structure moves from left to right under the action of the conveying device A3. The shot blasting shot out by the shot blasting machines 6 knocks off the rust on the surface of the passing steel structure. The dropped shot blasting and rust are respectively screened into the shot collecting tank 11 and the rust collecting tank 10 by the screen plate 9 under the guidance of the material guiding plate 8. The shot blasting in the shot collecting tank 11 moves to the shot distributing assembly 45 under the action of the conveying device B14 and is evenly dispersed into each shot storage box 7 for the shot blasting machines 6 to shoot out again. The steel structure that has completed the rust removal treatment moves to the right end of the conveying device A3 and is taken down by the staff. During after - maintenance, the staff can take away the accumulated sundries in the rust collecting tank 10 from the waste removing opening 42 and supplement new shot blasting into the shot collecting tank 11 from the supplementary shot blasting inlet 41.
