Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe stacking, and specifically to a stacking device and method for the production of high-strength square and rectangular steel pipes. Background Art

[0002] High-strength square and rectangular steel pipes are steel pipes with square or rectangular cross-sections, which are made of high-strength steel. These steel pipes are widely used due to their good mechanical properties, corrosion resistance, and high dimensional accuracy. They are usually used in building structures, bridge construction, tower mast structures, mechanical manufacturing, and other applications that require bearing large loads and resisting harsh environmental conditions. After the production of square and rectangular steel pipes is completed, they need to be stacked and then transferred.

[0003] Publication No. CN213833712U discloses a steerable steel pipe stacking device, which relates to the technical field of steel pipe stacking. The utility model includes a U-shaped frame and a moving base. A rectangular plate is fixed at the bottom end of one side of the U-shaped frame, and a first motor is bolted to the top end of the rectangular plate. The output end of the first motor and inside the U-shaped frame are clamped with a first screw rod. The first screw rod and the U-shaped frame are rotationally connected. The other side of the first screw rod is fixed with a second screw rod, and the first screw rod and the second screw rod have opposite helix directions. The second screw rod and the U-shaped frame are rotationally connected.

[0004] Although the above application and the prior art can fix steel pipes with different lengths and diameters and can quickly make adjustments according to steel pipes in different directions, in the actual use process of the above application and the prior art, in order to avoid collisions between steel pipes, it is necessary to use partitions to isolate the steel pipes. However, as the steel pipes are continuously stacked, the partitions at high positions need to be placed by the user with the help of lifting tools, and when placing the partitions, the partitions will collide with the steel pipes, thus causing damage to the steel pipes, so the subsequent use effect of the steel pipes is affected. Moreover, when placing the partitions, since gaps will be generated between the steel pipes during the stacking process, when the partitions move, one end of the partitions will hit the surface of the steel pipes, thus causing damage to the steel pipes. Therefore, we have proposed a stacking device and method for the production of high-strength square and rectangular steel pipes. Summary of the Invention

However, as the steel pipes are continuously stacked, the partitions at high positions need to be placed by users with the help of lifting tools, and when placing the partitions, the partitions will collide with the steel pipes, thus causing damage to the steel pipes, affecting the subsequent use effect of the steel pipes, and when placing the partitions, since gaps will be generated between the steel pipes during the stacking process of the steel pipes, when the partitions move, one end of the partitions will collide with the surface of the steel pipes, resulting in damage to the steel pipes.

[0027] (III) Beneficial effects

[0028] Compared with the prior art, the present invention provides a stacking device and method for the production of high-strength square and rectangular steel pipes, having the following beneficial effects:

[0029] 1. For the stacking device and method for the production of high-strength square and rectangular steel pipes, by using the plate discharging assembly, when the backing plate is located on top of the lifting screw plate, start the second driving motor through the control panel. The second driving motor drives the driving sprocket to rotate through the rotating column, and the driving sprocket drives the first driven sprocket to rotate through the chain, so that the first screw drives the backing plate to move to an appropriate height through the lifting screw plate. Then start the driving cylinder through the control panel, and the driving cylinder drives the push plate to move through the telescopic column, so that the push plate pushes the backing plate to move to the top of the square and rectangular steel pipe, thereby enabling the high-place square and rectangular steel pipes to be placed with backing plates, thus achieving the effect of placing at a high place.

[0030] 2. For the stacking device and method for the production of high-strength square and rectangular steel pipes, through the combined use of the plate discharging assembly and the anti-pressure assembly, when the driving cylinder drives the push plate to move through the telescopic column, the backing plate located on top of the lifting screw plate is not squeezed by other backing plates, so that the first spring located inside the fixed cylinder is no longer squeezed by the extension cylinder and returns to its original state. Furthermore, the first spring drives the extension cylinder to slide inside the fixed cylinder, and the extension cylinder drives the second roller to move out of the inside of the backing plate and the cushion block through the moving frame. Therefore, when the push plate drives the backing plate to move, the second roller will contact the square and rectangular steel pipe, thereby avoiding contact between the cushion block and the square and rectangular steel pipe, thus achieving the effect of preventing collision.

[0031] 3. The stacking device and method for the production of high-strength square and rectangular steel pipes, through the combined use of the plate output component and the anti-gap component, when the second driving motor drives the driving sprocket to rotate through the rotating column, the driving sprocket synchronously drives the second driven sprocket to rotate through the chain, so that the worm drives the second screw rod to rotate through the worm gear. During the rotation of the second screw rod, the moving screw block is driven to move, so that the moving screw block drives the gap plate to move through the receiving block and the extension block. As the gap plate moves, the gap plate pushes the square and rectangular steel pipes to move, so that there is no longer a gap between multiple square and rectangular steel pipes. Therefore, during the movement of the backing plate, the backing plate will not contact the surface of the square and rectangular steel pipes at one end due to the existence of the gap, thus achieving the effect of preventing gaps.

[0032] Other features and advantages of the present invention will be described in the following specification, and some of them will become obvious from the specification or be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained by the structures specifically pointed out in the written specification and the drawings.

Detailed implementation manners

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] In the embodiments of the present application, the devices or elements indicated by or implied must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically and precisely defined.

[0050] For the first specific embodiment, please refer to Figures 1 to 8 , a stacking device for the production of high-strength square and rectangular steel pipes, comprising: a stacking table 1 and a manipulator 121 arranged on the top of the stacking table 1,

[0051] The limiting plate 12 is fixedly connected to the top of the stacking table 1. The top of the limiting plate 12 is fixedly connected to the bottom of the robotic arm 121. The top of the stacking table 1 is fixedly and communicatively connected with a driving box 13, a moving box 14 and a plate placing box 15. A number of cushion plates 151 are arranged inside the plate placing box 15. The surface of the moving box 14 is fixedly connected with a control panel 141. One end of the stacking table 1 is fixedly connected with a handle 11. Two cushion blocks 152 are fixedly connected to the bottom of each of the number of cushion plates 151;

[0052] The plate feeding assembly 2 is arranged inside the stacking table 1 and is used for conveying the cushion plates 151 into the moving box 14. The plate feeding assembly 2 includes a first driving motor 21 fixedly connected inside the stacking table 1 and two frame toothed plates 22 slidably connected inside the stacking table 1. The output end of the first driving motor 21 is fixedly connected with a rotating rod 211. Two half gears 212 are fixedly connected to the surface of the rotating rod 211. The two half gears 212 are in meshing transmission with the two frame toothed plates 22. A pushing plate 221 is fixedly connected between the two frame toothed plates 22. The plate feeding assembly 2 further includes a support frame 23 fixedly connected to the backs of the two frame toothed plates 22. A number of first rollers 231 are rotatably connected to the top of the support frame 23;

[0053] The anti-pressure assembly 3 is arranged inside a number of cushion plates 151 and is used for preventing the cushion plates 151 from colliding with the square rectangular steel pipes;

[0054] The plate discharging assembly 4 is arranged inside the moving box 14 and is used for pushing the cushion plates 151;

[0055] The anti-gap assembly 5 is arranged inside the driving box 13 and is used for preventing gaps from occurring during the stacking process of the square rectangular steel pipes;

[0056] It should be noted that universal wheels are arranged at the bottom of the stacking table 1, and the universal wheels can be self-locked. One end of the rotating rod 211 away from the first driving motor 21 is rotatably connected inside the stacking table 1. Inclined platforms are fixedly connected to both ends of the frame toothed plate 22. The arrangement of the inclined platforms can prevent the cushion plates 151 from directly falling onto the top of the stacking table 1. The moving box 14 is fixedly and communicatively connected with the plate placing box 15;

[0057] When the backing plate 151 needs to be moved inside the moving box 14, the first driving motor 21 is started through the control panel 141. The first driving motor 21 drives the half gear 212 to rotate through the rotating rod 211, so that the half gear 212 drives the frame toothed plate 22 to move. When the frame toothed plate 22 moves, it synchronously drives the pushing plate 221 and the support frame 23 to move, so that the pushing plate 221 pushes the backing plate 151 to move inside the moving box 14. When the pushing plate 221 pushes the backing plate 151 to move, the support frame 23 moves to the bottom of another backing plate 151, so that the first roller 231 supports the other backing plate 151. When the frame toothed plate 22 returns to the initial state, the other backing plate 151 falls on the top of the stacking table 1;

[0058] Specific Embodiment Two. Please refer to Figures 1 to 8 , a stacking device for high-strength square and rectangular steel pipe production provided according to Specific Embodiment One. The present embodiment provides a further technical solution:

[0059] The plate discharging assembly 4 includes a second driving motor 41 fixedly connected inside the stacking table 1 and a first screw rod 42 rotatably connected between the moving box 14 and the stacking table 1. The output end of the second driving motor 41 is fixedly connected with a rotating column 411. The surface of the rotating column 411 is fixedly connected with a driving sprocket 412. The surface of the first screw rod 42 is fixedly connected with a first driven sprocket 421. The driving sprocket 412 and the first driven sprocket 421 are driven by a chain. The surface of the first screw rod 42 is threadedly connected with a lifting screw plate 43. The plate discharging assembly 4 further includes a guide rod 44 fixedly connected between the moving box 14 and the stacking table 1. The lifting screw plate 43 is slidably connected to the surface of the guide rod 44. The top of the lifting screw plate 43 is fixedly connected with a driving cylinder 431. The output end of the driving cylinder 431 is differentially connected with a telescopic column 432. One end of the telescopic column 432 away from the driving cylinder 431 is fixedly connected with a pushing plate 433;

[0060] It should be noted that one end of the rotating column 411 away from the second driving motor 41 is rotatably connected to the inner wall of the stacking table 1. The lifting screw plate 43 is slidably connected inside the moving box 14. When the first screw rod 42 drives the lifting screw plate 43 and the backing plate 151 to move, the lifting screw plate 43 can smoothly slide inside the moving box 14;

[0061] When the backing plate 151 needs to be placed at a high position, when the backing plate 151 enters the moving box 14, the backing plate 151 is located on top of the lifting screw plate 43. The second driving motor 41 is started through the control panel 141. The second driving motor 41 drives the driving sprocket 412 to rotate through the rotating column 411. The driving sprocket 412 drives the first driven sprocket 421 to rotate through the chain, so that the first screw rod 42 drives the backing plate 151 to move to an appropriate height through the lifting screw plate 43. Then, the driving cylinder 431 is started through the control panel 141. The driving cylinder 431 drives the push plate 433 to move through the telescopic column 432, so that the push plate 433 pushes the backing plate 151 to move to the top of the square rectangular steel pipe, so that the square rectangular steel pipe at a high position can be placed on the backing plate 151;

[0062] Specific embodiment three, please refer to Figures 1 to 11 , according to a stacking device for the production of high-strength square rectangular steel pipes provided by the second specific embodiment, the present embodiment provides a further technical solution:

[0063] The anti-pressure component 3 includes a fixed cylinder 31 fixedly connected inside a plurality of backing plates 151. A first spring 311 is fixedly connected inside the fixed cylinder 31. An extension cylinder 312 is slidably connected inside the fixed cylinder 31. The extension cylinder 312 is fixedly connected to one end of the first spring 311. A moving frame 32 is fixedly connected to the end of the extension cylinder 312 away from the first spring 311. A second roller 321 is rotatably connected inside the moving frame 32;

[0064] It should be noted that the force generated by the deformation of the first spring 311 is less than the weight of the backing plate 151 and the cushion block 152, and the force generated by the deformation of the first spring 311 is also less than the weight of the square rectangular steel pipe;

[0065] When it is necessary to avoid contact between the cushion block 152 at the bottom of the backing plate 151 and the top of the square rectangular steel pipe, when the driving cylinder 431 drives the push plate 433 to move through the telescopic column 432, the backing plate 151 located on top of the lifting screw plate 43 is not squeezed by other backing plates 151, so that the first spring 311 located inside the fixed cylinder 31 is no longer squeezed by the extension cylinder 312 and returns to its original state. Furthermore, the first spring 311 drives the extension cylinder 312 to slide inside the fixed cylinder 31. The extension cylinder 312 drives the second roller 321 to move out of the inside of the backing plate 151 and the cushion block 152 through the moving frame 32. Therefore, when the push plate 433 drives the backing plate 151 to move, the second roller 321 will contact the top of the square rectangular steel pipe, thereby avoiding direct contact between the backing plate 151 and the cushion block 152 and the surface of the square rectangular steel pipe;

[0066] Specific embodiment four, please refer to Figures 1 to 14 , according to a stacking device for the production of high-strength square rectangular steel pipes provided by the third specific embodiment, the present embodiment provides a further technical solution:

[0067] The anti-gap component 5 includes a worm 51 rotatably connected between the drive box 13 and the stacking table 1. A second driven sprocket 511 is fixedly connected to the surface of the worm 51 and inside the stacking table 1. The second driven sprocket 511 and the driving sprocket 412 are driven by a chain. The anti-gap component 5 further includes a second screw rod 52 rotatably connected inside the drive box 13. A worm gear 521 is fixedly connected to the surface of the second screw rod 52. The worm 51 and the worm gear 521 are in meshing transmission. A moving screw block 522 is threadedly connected to the surface of the second screw rod 52. The moving screw block 522 is slidably connected inside the drive box 13. Receiving blocks 53 are fixedly connected to both the surface and the back of the moving screw block 522. A second spring 531 is fixedly connected inside the receiving block 53. An extending block 532 is slidably connected inside the receiving block 53. One end of the extending block 532 is fixedly connected to one end of the second spring 531. The end of the extending block 532 away from the second spring 531 is fixedly connected to a gap plate 533. The gap plate 533 is slidably connected inside the limiting plate 12;

[0068] It should be noted that the force generated by the deformation of the second spring 531 is greater than the frictional force of the movement of the square rectangular steel pipe and less than the force generated by the deformation of the square rectangular steel pipe. The control panel 141 is electrically connected to the robotic arm 121, the first driving motor 21, the second driving motor 41, and the driving cylinder 431. The opening and closing of the robotic arm 121, the first driving motor 21, the second driving motor 41, and the driving cylinder 431 are controlled by pressing the operation buttons on the surface of the control panel 141;

[0069] When it is necessary to prevent gaps from generating between the square rectangular steel pipes, during the process that the second driving motor 41 drives the driving sprocket 412 to rotate through the rotating column 411, the driving sprocket 412 synchronously drives the second driven sprocket 511 to rotate through the chain, so that the worm 51 drives the second screw rod 52 to rotate through the worm gear 521. During the rotation of the second screw rod 52, the moving screw block 522 is driven to move. The moving screw block 522 drives the gap plate 533 to move through the receiving block 53 and the extending block 532. As the gap plate 533 moves, the gap plate 533 pushes the square rectangular steel pipe to move, so that there are no longer gaps between multiple square rectangular steel pipes. Therefore, during the movement of the cushion plate 151, one end of the cushion plate 151 will not come into contact with the surface of the square rectangular steel pipe due to the existence of the gap;

[0070] Specific Embodiment Five, the present invention also provides a stacking method for the production of high-strength square rectangular steel pipes. The stacking method specifically includes the following steps:

[0071] Step 1: Place the cushion plate 151 inside the plate placing box 15, and then place the square rectangular steel pipe between the two limiting plates 12 through the robotic arm 121;

[0072] Step 2: When the backing plate 151 needs to be placed on the top of the square rectangular steel pipe, by using the plate feeding assembly 2 and the plate discharging assembly 4, the backing plate 151 is placed on the top of the square rectangular steel pipe;

[0073] Step 3: When the backing plate 151 moves to the top of the square rectangular steel pipe, the anti-pressure assembly 3 is no longer extruded by other backing plates 151 and extends, so that the backing plate 151 does not collide with the top of the square rectangular steel pipe;

[0074] Step 4: When the plate discharging assembly 4 starts to operate, the plate discharging assembly 4 drives the anti-gap assembly 5 to operate, so that the anti-gap assembly 5 extrudes multiple square rectangular steel pipes, thereby ensuring that the backing plate 151 does not collide with the square rectangular steel pipe due to gaps during the moving process.

[0075] Working principle: When in use, move the stacking table 1 to a suitable position through the handle 11 and fix it. Then, place multiple backing plates 151 in the plate storage box 15. Next, start the robotic arm 121 through the control panel 141, and place multiple square and rectangular steel pipes between the two limiting plates 12 by the robotic arm 121. When it is necessary to move the backing plate 151 into the interior of the moving box 14, start the first driving motor 21 through the control panel 141. The first driving motor 21 drives the semi-gear 212 to rotate through the rotating rod 211, causing the semi-gear 212 to drive the frame toothed plate 22 to move. When the frame toothed plate 22 moves, it synchronously drives the pushing plate 221 and the support frame 23 to move, so that the pushing plate 221 pushes the backing plate 151 into the interior of the moving box 14. When the pushing plate 221 pushes the backing plate 151 to move, the support frame 23 moves to the bottom of another backing plate 151, so that the first roller 231 supports another backing plate 151. When the frame toothed plate 22 returns to its initial state, another backing plate 151 falls onto the top of the stacking table 1. When it is necessary to place the backing plate 151 at a high position, when the backing plate 151 enters the moving box 14, the backing plate 151 is located on the top of the lifting screw plate 43. Start the second driving motor 41 through the control panel 141. The second driving motor 41 drives the driving sprocket 412 to rotate through the rotating column 411. The driving sprocket 412 drives the first driven sprocket 421 to rotate through the chain, so that the first screw rod 42 drives the backing plate 151 to move to a suitable height through the lifting screw plate 43. Then, start the driving cylinder 431 through the control panel 141. The driving cylinder 431 drives the pushing plate 433 to move through the telescopic column 432, so that the pushing plate 433 pushes the backing plate 151 to move to the top of the square and rectangular steel pipe, so that the square and rectangular steel pipe at a high position can be placed on the backing plate 151. When it is necessary to prevent the contact between the cushion block 152 at the bottom of the backing plate 151 and the top of the square and rectangular steel pipe, when the driving cylinder 431 drives the pushing plate 433 to move through the telescopic column 432, the backing plate 151 located on the top of the lifting screw plate 43 is not squeezed by other backing plates 151, so that the first spring 311 located inside the fixed cylinder 31 is no longer squeezed by the extension cylinder 312 and returns to its original state. Furthermore, the first spring 311 drives the extension cylinder 312 to slide inside the fixed cylinder 31, and the extension cylinder 312 drives the second roller 321 to move out of the interior of the backing plate 151 and the cushion block 152 through the moving frame 32. Therefore, when the pushing plate 433 drives the backing plate 151 to move, the second roller 321 will contact the top of the square and rectangular steel pipe, thus preventing the backing plate 151 and the cushion block 152 from directly contacting the surface of the square and rectangular steel pipe. When it is necessary to prevent gaps from generating between the square and rectangular steel pipes, when the second driving motor 41 drives the driving sprocket 412 to rotate through the rotating column 411, the driving sprocket 412 synchronously drives the second driven sprocket 511 to rotate through the chain, so that the worm 51 drives the second screw rod 52 to rotate through the worm gear 521. During the rotation of the second screw rod 52, it drives the moving screw block 522 to move.The moving screw block 522 drives the void plate 533 to move through the receiving block 53 and the extension block 532. As the void plate 533 moves, the void plate 533 pushes the square rectangular steel pipe to move, so that there is no longer a void between multiple square rectangular steel pipes. Therefore, during the movement of the backing plate 151, one end of the backing plate 151 will not come into contact with the surface of the square rectangular steel pipe due to the existence of the void.
