Description

Technical Field

[0001] This invention belongs to the field of flipping platform technology, and specifically relates to a hydraulic flipping spraying platform. Background Technology

[0002] Before casting in a sandbox, a release solvent needs to be sprayed inside the sandbox; and after the sandbox has completed the demolding process, any excess solvent needs to be recycled.

[0003] In related technologies, by setting up lifting shafts on both sides of the sandbox and placing the lifting shafts at the center of gravity of the sandbox, the user can use steel wire ropes to suspend the lifting shafts and flip the sandbox to spray the inside of the sandbox. At the same time, this method can also be used to put the sandbox in a semi-inverted state to pour out the solvent inside the sandbox.

[0004] The above method requires manual operation, which is not only difficult to operate and has a low safety factor, but also takes a long time and reduces work efficiency. Summary of the Invention

[0014] In the above technical solution, the first connecting beam is T-shaped and the second connecting beam is T-shaped.

[0015] The hydraulic tilting spraying platform of the present invention has the following advantages compared with the prior art:

[0016] 1. By mounting the first and second tensioning rings onto the lifting shafts on both sides of the sand box, the sand box is fixed to the support plate, allowing the support plate and the sand box to rotate synchronously and thus tilting the sand box. Tilting the sand box puts it in a semi-inverted state, facilitating the spraying of release agent onto the interior of the sand box. It also allows excess solvent to be poured out and collected easily. Using this structure, tilting the sand box via the support plate is simpler, safer, and faster than manually lifting and tilting the sand box for spraying, thus improving work efficiency. Since the lifting shafts are located at the center of gravity of the sand box, the first and second tensioning rings tighten the shafts, ensuring that the tilted and fixed position of the sand box remains at its center of gravity when tilting sand boxes of different sizes, thus improving product applicability. By moving the first slider and the second tensioning cylinder with the sliding cylinder, the distance between the second tensioning ring and the first tensioning ring can be adjusted, enabling the product to flip sandboxes of different sizes, thus further improving the product's applicability. Simultaneously, by moving the first slider and the second tensioning cylinder with the sliding cylinder, the second tensioning ring can be fitted onto the outside of the lifting shaft, making it easier to clamp the sandbox and improving the user experience.

[0017] 2. By fixing two first guide rails to the bottom of the support plate and positioning them on both sides of the first slider, and simultaneously placing two first guide parts on both sides of the first slider and embedding them into the first guide grooves, the first slider can move along the first guide rails via the first guide parts, thereby preventing the first slider from deviating during movement and improving the stability of the first slider's movement. By setting the first guide grooves to be triangular and adapting them to the first guide parts, the first slider can be engaged with the first guide rails via the first guide parts, ensuring that the first slider can move along the first guide rails while preventing it from detaching from them, thus improving the user experience of the product.

[0018] 3. By attaching the limiting plate to the sandbox, the limiting plate supports the sandbox when the support plate causes the sandbox to flip, thereby preventing the sandbox from moving downward due to gravity. This allows the sandbox to flip 110 degrees, so that excess solvent can be poured out from the inside of the sandbox.

[0019] 4. By fixing two second guide rails to the bottom of the support plate and positioning them on both sides of the second slider, and simultaneously placing two second guide parts on both sides of the second slider and embedding them into the second guide grooves, the second slider can move along the second guide rails via the second guide parts, thus preventing the second slider from deviating during movement and improving the stability of the second slider's movement. By setting the second guide grooves to be triangular and adapting them to the second guide parts, the second slider can be engaged with the second guide rails via the second guide parts, ensuring that the second slider can move along the second guide rails while preventing it from detaching, thereby improving the user experience of the product.

[0020] 5. By fixing two rotating seats to the top of the support plate and rotatably connecting the two rotating seats to the second output shaft of the tilting cylinder, the tilting cylinder drives the upper part of the support plate to rotate through the rotating seats, thereby reducing the length of the first output shaft of the tilting cylinder to extend, thus increasing the thrust and reducing the power required by the tilting cylinder.

[0021] 6. By connecting two limiting columns to the bottom of the support plate and making the limiting columns fit against the ground, the limiting columns support the support plate when it is in a horizontal state, thereby improving the stability of the support plate and the sandbox.

[0022] 7. By moving the first connecting beam with the first tensioning cylinder and the second connecting beam with the second tensioning cylinder, the sand box is fixed to the support plate when there are two or more lifting shafts on each side of the sand box.

[0023] 8. By setting the first connecting beam to a T-shape and the second connecting beam to a T-shape, the strength of the first connecting beam and the second connecting beam is increased, thereby preventing the first connecting beam and the second connecting beam from bending.

Detailed Implementation

[0034] The following are specific implementation cases and appendices. Figure 1-8 The present invention will be further described, but the present invention is not limited to these embodiments.

[0035] A hydraulic tilting spraying platform, such as Figures 1 to 8As shown, the hydraulic tilting spraying platform tilts the sandbox 10. At least one lifting shaft 11 is provided on both sides of the sandbox 10. The hydraulic tilting spraying platform includes: a support base 12, a support plate 13, a tilting cylinder 14, a first tensioning cylinder 15, a first tensioning ring 16, a first slide groove 17, a first slider 18, a sliding cylinder 19, a second tensioning cylinder 20, and a second tensioning ring 21. Two support bases 12 are fixed to the ground, and there is a gap between the two support bases 12. Both ends of the support plate 13 are rotatably connected to the two support bases 12, and the sandbox 10 is placed on the support plate 13. The tilting cylinder 14 is provided with a first output shaft. The two tilting cylinders 14 are fixed to the ground, and the first output shafts of the two tilting cylinders 14 are rotatably connected to the support plate 13. The first tensioning cylinder 15 is provided with a second output shaft. 15 is fixed to the bottom of support plate 13, and the second output shaft passes through support plate 13; the first tensioning ring 16 is rotatably connected to the second output shaft, and the first tensioning ring 16 is fitted on the outside of the hoisting shaft 11 on one side of sand box 10; the first slide groove 17 is provided on support plate 13, and the first slide groove 17 is located at the bottom of sand box 10; the first slider 18 is embedded in the first slide groove 17; the sliding cylinder 19 is provided with a third output shaft, the sliding cylinder 19 is fixed to the bottom of support plate 13, and the third output shaft is connected to the first slider 18; the second tensioning cylinder 20 is provided with a fourth output shaft, the second tensioning cylinder 20 is fixed to the bottom of the first slider 18, and the fourth output shaft passes through the first slider 18; the second tensioning ring 21 is rotatably connected to the fourth output shaft, and the second tensioning ring 21 is fitted on the outside of the hoisting shaft 11 on the other side of sand box 10.

[0036] By fixing two support bases 12 to the ground and rotatably connecting both ends of the support plate 13 to the two support bases 12 respectively, the two support bases 12 support the support plate 13, thereby enabling the support plate 13 to rotate between the two support bases 12. By fixing two tilting cylinders 14 to the ground and rotatably connecting the first output shaft of the two tilting cylinders 14 to the support plate 13, the two tilting cylinders 14 drive the support plate 13 to rotate around the connection between the support bases 12 and the support plate 13. By fixing the first tensioning cylinder 15 to the bottom of the support plate 13 and rotatably connecting the first tensioning ring 16 to the second output shaft of the first tensioning cylinder 15, and fitting the first tensioning ring 16 onto the outside of the hoisting shaft 11 on one side of the sandbox 10, the first tensioning cylinder 15 can drive the first tensioning ring 16 to move, thereby enabling the first tensioning ring 16 to tighten the hoisting shaft 11 on one side of the sandbox 10, thus improving the stability of the sandbox 10. By setting the first groove 17 on the support plate 13 and embedding the first slider 18 into the first groove 17, the first slider 18 can move within the first groove 17. By fixing the sliding cylinder 19 to the bottom of the support plate 13 and connecting the third output shaft of the sliding cylinder 19 to the slider, the sliding cylinder 19 drives the first slider 18 to move within the first groove 17. By fixing the second tensioning oil pipe to the bottom of the first slider 18 and passing the fourth output shaft of the second tensioning cylinder 20 through the first slider 18, the second tensioning cylinder 20 and the first slider 18 move synchronously. By rotating the second tensioning ring 21 and the fourth output shaft and fitting the second tensioning ring 21 onto the outside of the hoisting shaft 11 on the other side of the sandbox 10, the second tensioning cylinder 20 can drive the second tensioning ring 21 to move, thereby tightening the hoisting shaft 11 on the other side of the sandbox 10 and improving the stability of the sandbox 10.

[0037] When using the product, ensure the support plate 13 is horizontal, place the sandbox 10 on the support plate 13, positioning the sandbox 10 between the first tensioning ring 16 and the second tensioning ring 21, and position the lifting shaft 11 on one side of the sandbox 10 on one side of the first tensioning rod, with the first tensioning ring 16 and the second tensioning ring 21 in a horizontal position. Then, rotate the first tensioning ring 16 so that it fits onto the outside of the lifting shaft 11. Simultaneously, activate the sliding cylinder 19, causing it to drive the third output shaft to move the first slider 18 toward the sandbox 10. When the fourth output shaft of the second tensioning cylinder 20 is below the lifting shaft 11 on the other side of the sandbox 10, stop the sliding cylinder 19. The first slider 18 is stopped from moving; then, the second tension ring 21 is rotated so that it is fitted onto the outside of the lifting shaft 11; then, the first tension cylinder 15 and the second tension cylinder 20 are activated simultaneously, so that the first tension cylinder 15 and the second tension cylinder 20 respectively drive the first tension ring 16 and the second tension ring 21 to move, so that the first tension ring 16 and the second tension ring 21 respectively come into contact with the two lifting shafts 11, thereby fixing the sand box 10 on the support plate 13 and improving the stability of the sand box 10; then, the tilting cylinder 14 is activated so that the tilting cylinder 14 pushes the support plate 13 to rotate around the connection between the support base 12 and the support plate 13, thereby tilting the sand box 10.

[0038] By mounting the first tensioning ring 16 and the second tensioning ring 21 onto the lifting shafts 11 on both sides of the sandbox 10, the sandbox 10 is fixed to the support plate 13, thereby enabling the support plate 13 and the sandbox 10 to rotate synchronously and thus flip the sandbox 10. By flipping the sandbox 10, it is placed in a semi-inverted state, facilitating the spraying of release agent onto the interior of the sandbox 10. Simultaneously, it allows excess solvent to be poured out from the interior of the sandbox 10, facilitating its collection. Using this structure, with the support plate 13 driving the sandbox 10 to flip, the operation is simpler, safer, and faster than manually lifting and flipping the sandbox 10 for spraying. This also improves work efficiency. Since the lifting shaft 11 is located at the center of gravity of the sandbox 10, the first tensioning ring 16 and the second tensioning ring 21 are used to tighten the lifting shaft 11. This ensures that when flipping sandboxes 10 of different sizes, the position where the sandbox 10 is flipped and fixed is always at the center of gravity, thus improving the product's applicability. By moving the first slider 18 and the second tensioning cylinder 20 driven by the sliding cylinder 19, the distance between the second tensioning ring 21 and the first tensioning ring 16 is adjusted, enabling the product to flip sandboxes 10 of different sizes, further improving its applicability. Simultaneously, by moving the first slider 18 and the second tensioning cylinder 20 driven by the sliding cylinder 19, the second tensioning ring 21 can be fitted onto the outside of the lifting shaft 11, making it easier to clamp the sandbox 10 and improving the user experience.

[0039] Specifically, the connection point between the support base 12 and the support plate 13 is 750-800mm above the ground, and the horizontal distance between the connection point and the lifting shaft 11 is 0-200mm. By setting the height of the connection point between the support base 12 and the support plate 13 above the ground to 750-800mm, the support plate 13 and the sandbox 10 can rotate around a position 750-800mm above the ground, facilitating the user's spraying operation inside the sandbox 10. By setting the horizontal distance between the connection point between the support base 12 and the support plate 13 and the lifting shaft 11 to 0-200mm, the work required for the tilting cylinder 14 is reduced, thus saving energy.

[0040] Specifically, a water tank is provided below the support plate 13 to collect the poured solvent.

[0041] In embodiments of the present invention, such as Figures 1 to 8As shown, the hydraulic flip-over spraying platform also includes: a first guide rail 22 and a first guide part 23; the first guide rail 22 is provided with a first guide groove, the two first guide rails 22 are fixed to the bottom of the support plate 13, and the two first guide rails 22 are located on both sides of the first slider 18; the two first guide parts 23 are provided on both sides of the first slider 18, and the first guide parts 23 are embedded in the first guide groove; wherein, the first guide groove is triangular, and the first guide groove is adapted to the first guide part 23.

[0042] By fixing two first guide rails 22 to the bottom of the support plate 13 and positioning them on both sides of the first slider 18, and simultaneously placing two first guide portions 23 on both sides of the first slider 18 and embedding them into the first guide grooves, the first slider 18 can move along the first guide rails 22 via the first guide portions 23, thereby preventing the first slider 18 from deviating during movement and improving the stability of the first slider 18's movement. By setting the first guide groove as a triangle and adapting it to the first guide portion 23, the first slider 18 can be engaged with the first guide rail 22 via the first guide portion 23, ensuring that the first slider 18 can move along the first guide rail 22 while preventing it from detaching from the first guide rail 22, thus improving the user experience of the product.

[0043] In embodiments of the present invention, such as Figures 1 to 8 As shown, the hydraulic tilting spraying platform also includes: a second slide groove 24, a second slider 25, a limiting cylinder 26, and a limiting plate 27; the two second slide grooves 24 are set on the support plate 13, and the second slide grooves 24 are perpendicular to the first slide groove 17; the two second sliders 25 are respectively embedded in the two second slide grooves 24; the limiting cylinder 26 is provided with a fifth output shaft, the two limiting cylinders 26 are fixed to the bottom of the support plate 13, and the fifth output shaft of the limiting cylinder 26 is connected to the second slider 25; the limiting plate 27 is connected to the second slider 25, and the limiting plate 27 is in contact with the sand box 10.

[0044] Two second slides 24 are mounted on the support plate 13, and two second sliders 25 are respectively embedded in the two second slides 24 to enable the second sliders 25 to move within the second slides 24. Two limiting cylinders 26 are fixed to the bottom of the support plate 13, and the fifth output shaft of the limiting cylinders 26 is connected to the second sliders 25 to enable the limiting cylinders 26 to drive the fifth output shaft to move the second sliders 25 within the second slides 24. By connecting the limiting plate 27 to the second sliders 25 and fitting the limiting plate 27 against the sandbox 10, the limiting plate 27 and the second sliders 25 move synchronously, thereby enabling the limiting plate 27 to limit and support the sandbox 10, thus improving the stability of the sandbox 10.

[0045] With the above structure, by attaching the limiting plate 27 to the sand box 10, the limiting plate 27 supports the sand box 10 when the support plate 13 drives the sand box 10 to flip, thereby preventing the sand box 10 from moving downward due to gravity, and thus enabling the sand box 10 to flip 110 degrees so that excess solvent can be poured out from the inside of the sand box 10.

[0046] Specifically, the two limiting plates 27 are located at one-quarter and one-half of the support plate 13, respectively, so that the two limiting plates 27 can support sandboxes 10 of different sizes.

[0047] Specifically, the two limit cylinders 26 are controlled to move, thereby enabling the two limit plates 27 to clamp the uneven outer wall of the sand box 10.

[0049] By fixing two second guide rails 28 to the bottom of the support plate 13 and positioning them on both sides of the second slider 25, and simultaneously placing two second guide portions 29 on both sides of the second slider 25 and embedding them into the second guide grooves, the second slider 25 can move along the second guide rails 28 via the second guide portions 29, thereby preventing the second slider 25 from deviating during movement and improving the stability of the movement of the second slider 25. By setting the second guide grooves to be triangular and adapting them to the second guide portions 29, the second slider 25 can be engaged with the second guide rails 28 via the second guide portions 29, ensuring that the second slider 25 can move along the second guide rails 28 while preventing it from disengaging from the second guide rails 28, thereby improving the user experience of the product.

[0050] In embodiments of the present invention, such as Figures 1 to 8 As shown, the hydraulic tilting spraying platform also includes: a rotating seat 30; two rotating seats 30 are fixed on the top of the support plate 13, and the two rotating seats 30 are respectively rotatably connected to the second output shaft of the tilting cylinder 14.

[0051] By fixing two rotating seats 30 to the top of the support plate 13 and rotatably connecting the two rotating seats 30 to the second output shaft of the tilting cylinder 14, the tilting cylinder 14 drives the upper part of the support plate 13 to rotate through the rotating seats 30, thereby reducing the length of the first output shaft of the tilting cylinder 14 to extend, thereby increasing the thrust and reducing the power required by the tilting cylinder 14.

[0052] In embodiments of the present invention, such as Figures 1 to 8 As shown, the hydraulic tilting spraying platform also includes: limiting columns 31; the two limiting columns 31 are connected to the bottom of the support plate 13, and the limiting columns 31 are in contact with the ground.

[0053] By connecting the two limiting columns 31 to the bottom of the support plate 13 and making the limiting columns 31 fit against the ground, the limiting columns 31 support the support plate 13 when it is in a horizontal state, thereby improving the stability of the support plate 13 and the sandbox 10.

[0054] In embodiments of the present invention, such as Figures 1 to 8 As shown, the hydraulic tilting spraying platform further includes: a first connecting seat 32, a first connecting shaft, a first connecting beam 33, a second connecting seat 34, a second connecting shaft, and a second connecting beam 35; the first connecting seat 32 is a hollow cavity with an opening at one end, and a first tensioning ring 16 is embedded in the first connecting seat 32; the first connecting shaft passes through the first connecting seat 32 and the first tensioning ring 16 in sequence; the first connecting beam 33 is connected to the other end of the first connecting seat 32; the second connecting seat 34 is a hollow cavity with an opening at one end, and a second tensioning ring 21 is embedded in the second connecting seat 34; the second connecting shaft passes through the second connecting seat 34 and the second tensioning ring 21 in sequence; the second connecting beam 35 is connected to the other end of the second connecting seat 34.

[0055] By embedding the first tensioning ring 16 into the first connecting seat 32 and passing the first connecting shaft through the first connecting seat 32 and the first tensioning ring 16 in sequence, the first connecting seat 32 and the first tensioning ring 16 are connected together. Simultaneously, the first connecting beam 33 is connected to the first connecting seat 32 by welding, so that the first tensioning cylinder drives the first tensioning ring 16, the first connecting seat 32, and the first connecting beam 33 to move synchronously. Similarly, by embedding the second tensioning ring 21 into the second connecting seat 34 and passing the second connecting shaft through the second connecting seat 34 and the second tensioning ring 21 in sequence, the second connecting seat 34 and the second tensioning ring 21 are connected together. Simultaneously, the second connecting beam 35 is connected to the second connecting seat 34 by welding, so that the second tensioning cylinder drives the second tensioning ring 21, the second connecting seat 34, and the second connecting beam 35 to move synchronously.

[0056] With the above structure, by moving the first connecting beam 33 with the first tensioning cylinder and moving the second connecting beam 35 with the second tensioning cylinder, the sand box 10 is fixed on the support plate 13 when there are two or more lifting shafts 11 on each side of the sand box 10.

[0057] In embodiments of the present invention, such as Figures 1 to 8 As shown, the first connecting beam 33 is T-shaped, and the second connecting beam 35 is T-shaped.

[0058] By setting the first connecting beam 33 and the second connecting beam 35 to a T-shape, the strength of the first connecting beam 33 and the second connecting beam 35 is increased, thereby preventing the first connecting beam 33 and the second connecting beam 35 from bending.
