Description

Technical Field

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

[0002] High-strength square steel pipe is a steel pipe with a square or rectangular cross-section. It is made of high-strength steel. This type of steel pipe is widely used due to its good mechanical properties, corrosion resistance and high dimensional accuracy. They are usually used in building structures, bridge construction, tower mast structures, machinery manufacturing and other applications that need to withstand large loads and withstand harsh environmental conditions. After the square steel pipe is produced, it needs to be stacked and then transferred.

[0003] Publication No. CN213833712U discloses a steerable steel pipe stacking device, relating to the technical field of steel pipe stacking. The utility model comprises a U-shaped frame and a movable base. A rectangular plate is fixed to the bottom end of one side of the U-shaped frame. A first motor is bolted to the top end of the rectangular plate. A first screw is clamped to the output end of the first motor, located inside the U-shaped frame. The first screw is connected to the U-shaped frame by rotation. A second screw is fixed to the other side of the first screw, and the first and second screws rotate in opposite directions. The second screw is connected to the U-shaped frame by rotation.

[0004] Although the above-mentioned application and the prior art can fix steel pipes of different lengths and diameters, and can quickly adjust steel pipes according to different directions, in the actual use process of the above-mentioned application and the prior art, in order to avoid collisions between steel pipes, partitions need to be used to isolate the steel pipes. However, as the steel pipes continue to accumulate, the partitions at high places need to be placed by the user with the help of lifting tools, and when the partitions are placed, the partitions will collide with the steel pipes, thereby causing damage to the steel pipes, thereby affecting the subsequent use of the steel pipes. Moreover, when the partitions are placed, gaps will be generated between the steel pipes during the process of stacking the steel pipes. Therefore, when the partitions are moved, one end of the partition will collide with the surface of the steel pipe, thereby causing damage to the steel pipe. Therefore, we propose a stacking device and method for the production of high-strength square steel pipes. Summary of the Invention

However, as the steel pipes continue to accumulate, the high-placed partitions need to be placed by the user with the help of lifting tools, and when the partitions are placed, the partitions will collide with the steel pipes, thereby causing damage to the steel pipes, thereby affecting the subsequent use of the steel pipes. Moreover, when the partitions are placed, gaps will be generated between the steel pipes during the process of stacking the steel pipes.

[0027] (3) Beneficial effects

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

[0029] 1. The stacking device and method for the production of high-strength square steel tubes, through the use of a plate-discharging assembly, when the pad is located on the top of the lifting screw plate, the second drive motor is started through the control panel, the second drive motor drives the active sprocket to rotate through the rotating column, the active sprocket drives the first driven sprocket to rotate through the chain, so that the first screw drives the pad to move to a suitable height through the lifting screw plate, and then the drive cylinder is started through the control panel, the drive cylinder drives the push plate to move through the telescopic column, so that the push plate pushes the pad to the top of the square steel tube, so that the square steel tube at a high place can be placed with the pad, thereby achieving the effect of high placement.

[0030] 2. The stacking device and method for the production of high-strength square steel tubes use a plate-out assembly in conjunction with an anti-pressure assembly. When the driving cylinder drives the push plate to move via the telescopic column, the pad located on the top of the lifting screw plate is not squeezed by other pads, so that the first spring located inside the fixed tube is no longer squeezed by the extension tube and returns to its original state, thereby causing the first spring to drive the extension tube to slide inside the fixed tube, and the extension tube drives the second roller to move out of the pad and the pad block via the movable frame. Therefore, when the push plate drives the pad to move, the second roller will contact the square steel tube, thereby preventing the pad block from contacting the square steel tube, thereby achieving the effect of preventing collision.

[0031] 3. The stacking device and method for the production of high-strength square steel tubes are used in conjunction with the plate-discharging assembly and the anti-gap assembly. When the second drive 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 to rotate through the worm wheel. During the rotation, the second screw drives the moving screw block 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 steel tube to move, thereby eliminating gaps between the multiple square steel tubes. Therefore, during the movement of the pad, one end of the pad will not contact the surface of the square steel tube due to the existence of the gap, thereby achieving the effect of preventing gaps.

[0032] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] In the embodiments of the present application, any device or element referred to or implied must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "plurality" is two or more, unless otherwise specifically specified.

[0050] For specific embodiment 1, please refer to Figures 1 to 8 A stacking device for producing high-strength square steel pipes includes a stacking platform 1 and a robotic arm 121 disposed on top of the stacking platform 1.

[0051] The limiting plate 12 is fixedly connected to the top of the stacking platform 1. The top of the limiting plate 12 is fixedly connected to the bottom of the robotic arm 121. The top of the stacking platform 1 is fixedly connected to the driving box 13, the moving box 14 and the board placing box 15. The board placing box 15 is provided with a plurality of pads 151 inside. The surface of the moving box 14 is fixedly connected to the control panel 141. One end of the stacking platform 1 is fixedly connected to the handle 11. The bottoms of the plurality of pads 151 are fixedly connected to two pads 152.

[0052] The feed plate assembly 2 is arranged inside the stacking platform 1 and is used to transport the pad 151 to the inside of the mobile box 14. The feed plate assembly 2 includes a first drive motor 21 fixedly connected to the inside of the stacking platform 1 and two frame tooth plates 22 slidably connected to the inside of the stacking platform 1. The output end of the first drive motor 21 is fixedly connected to a rotating rod 211. The surface of the rotating rod 211 is fixedly connected to two half gears 212. The two half gears 212 are engaged with the two frame tooth plates 22 for transmission. A pusher plate 221 is fixedly connected between the two frame tooth plates 22. The feed plate assembly 2 also includes a support frame 23 fixedly connected to the back of the two frame tooth plates 22. The top of the support frame 23 is rotatably connected to a plurality of first rollers 231;

[0053] The anti-pressure component 3 is arranged inside the plurality of pads 151 to prevent the pads 151 from colliding with the square steel tubes;

[0054] The plate-out assembly 4 is provided inside the moving box 14 and is used to push the pad 151;

[0055] The anti-gap component 5 is arranged inside the driving box 13 and is used to prevent the square steel pipes from generating gaps during the stacking process;

[0056] It should be noted that a universal wheel is provided at the bottom of the stacking platform 1, and the universal wheel can be self-locking. The end of the rotating rod 211 away from the first drive motor 21 is rotatably connected to the inside of the stacking platform 1, and both ends of the frame tooth plate 22 are fixedly connected to the inclined platform. The setting of the inclined platform can prevent the pad 151 from falling directly to the top of the stacking platform 1, and the mobile box 14 is fixedly connected to the board box 15;

[0057] When it is necessary to move the pad 151 to the inside of the mobile box 14, the first drive motor 21 is started through the control panel 141. The first drive motor 21 drives the half gear 212 to rotate through the rotating rod 211, so that the half gear 212 drives the frame tooth plate 22 to move. When the frame tooth plate 22 moves, the push plate 221 and the support frame 23 are synchronously driven to move, so that the push plate 221 pushes the pad 151 to move to the inside of the mobile box 14. When the push plate 221 pushes the pad 151 to move, the support frame 23 moves to the bottom of the other pad 151, so that the first roller 231 supports the other pad 151. When the frame tooth plate 22 returns to its initial state, the other pad 151 falls on the top of the stacking platform 1.

[0058] For specific embodiment 2, please refer to Figures 1 to 8 According to the stacking device for producing high-strength square steel pipes provided in the first embodiment, this embodiment provides a further technical solution:

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

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

[0061] When the pad 151 needs to be placed at a high place, when the pad 151 enters the moving box 14, the pad 151 is located at the top of the lifting screw plate 43, and 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, and the driving sprocket 412 drives the first driven sprocket 421 to rotate through the chain, so that the first screw 42 drives the pad 151 to move to a suitable height through the lifting screw plate 43, and 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 pad 151 to the top of the square steel pipe, so that the square steel pipe at a high place can be placed with the pad 151;

[0062] For specific example three, please refer to Figures 1 to 11 According to the stacking device for producing high-strength square steel pipes provided in the second specific embodiment, this embodiment provides a further technical solution:

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

[0064] It should be noted that the deformation force generated by the first spring 311 is smaller than the weight of the pad 151 and the pad 152, and the deformation force generated by the first spring 311 is also smaller than the weight of the square steel tube;

[0065] When the driving cylinder 431 drives the push plate 433 to move via the telescopic column 432, the pad 151 located on the top of the lifting screw plate 43 is not squeezed by other pads 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 shape, thereby causing the first spring 311 to drive 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 pad 151 and the pad 152 through the moving frame 32. Therefore, when the push plate 433 drives the pad 151 to move, the second roller 321 will contact the top of the square steel tube, thereby preventing the pad 151 and the pad 152 from directly contacting the surface of the square steel tube.

[0066] For specific example 4, please refer to Figures 1 to 14 According to the stacking device for producing high-strength square steel pipes provided in the third embodiment, this embodiment provides a further technical solution:

[0067] The anti-backlash component 5 includes a worm 51 rotatably connected between the drive box 13 and the stacking platform 1, and a second driven sprocket 511 is fixedly connected to the surface of the worm 51 and located inside the stacking platform 1. The second driven sprocket 511 and the driving sprocket 412 are driven by a chain. The anti-backlash component 5 also includes a second screw 52 rotatably connected to the inside of the drive box 13, and a worm wheel 521 is fixedly connected to the surface of the second screw 52. The worm 51 and the worm wheel 521 are meshed for transmission. The surface of the second screw 52 is threadedly connected to the The movable screw block 522 is slidably connected to the interior of the driving box 13. The surface and back of the movable screw block 522 are fixedly connected to the storage block 53. The interior of the storage block 53 is fixedly connected to the second spring 531. The interior of the storage block 53 is slidably connected to the extension block 532. One end of the extension block 532 is fixedly connected to one end of the second spring 531. The end of the extension block 532 away from the second spring 531 is fixedly connected to the gap plate 533. The gap plate 533 is slidably connected to the interior of the limiting plate 12.

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

[0069] When it is necessary to prevent gaps from being generated between the square and rectangular steel tubes, 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 52 to rotate through the worm wheel 521, and the second screw 52 drives the moving screw block 522 to move during the rotation process, so that 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 and rectangular steel tubes to move, thereby eliminating gaps between the multiple square and rectangular steel tubes. Therefore, during the movement of the pad 151, the pad 151 will not cause one end of the pad 151 to come into contact with the surface of the square and rectangular steel tube due to the existence of the gap.

[0070] Specific embodiment 5, the present invention also provides a stacking method for producing high-strength square steel pipes, the stacking method specifically comprising the following steps:

[0071] Step 1: Place the pad 151 inside the board box 15, and then use the robotic arm 121 to place the square steel pipe between the two limit plates 12;

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

[0073] Step 3: When the pad 151 moves to the top of the square steel tube, the anti-pressure component 3 is no longer squeezed by other pads 151 and extends, so that the pad 151 does not collide with the top of the square steel tube;

[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 squeezes the multiple square steel pipes, thereby ensuring that the pad 151 will not collide with the square steel pipes due to gaps during movement.

[0075] Working principle: When in use, the stacking platform 1 is moved to a suitable position and fixed through the handle 11, and then multiple pads 151 are placed in the board box 15, and then the mechanical arm 121 is started through the control panel 141. Multiple square steel pipes are placed between the two limit plates 12 through the mechanical arm 121. When it is necessary to move the pad 151 to the inside of the mobile box 14, the first drive motor 21 is started through the control panel 141. The first drive motor 21 drives the half gear 212 to rotate through the rotating rod 211, so that the half gear 212 drives the frame tooth plate 22 to move. When the frame tooth plate 22 moves, it simultaneously drives the push plate 221 and the support frame 23 to move, so that the push plate 221 pushes the pad 151 to move to the inside of the mobile box 14 When the push plate 221 pushes the pad 151 to move, the support frame 23 moves to the bottom of the other pad 151, so that the first roller 231 supports the other pad 151. When the frame tooth plate 22 returns to its initial state, the other pad 151 falls on the top of the stacking platform 1. When the pad 151 needs to be placed at a high place, when the pad 151 enters the moving box 14, the pad 151 is located on the top of the lifting screw plate 43, and the second drive motor 41 is started through the control panel 141. The second drive motor 41 drives the active sprocket 412 to rotate through the rotating column 411, and the active sprocket 412 drives the first driven sprocket 421 to rotate through the chain, so that the first screw 42 drives the pad 151 to move to the lifting screw plate 43. When the driving cylinder 431 drives the push plate 433 to move through the telescopic column 432, the push plate 433 pushes the pad 151 to the top of the square steel pipe, so that the square steel pipe at a high position can be placed on the pad 151. It is necessary to avoid the pad 152 at the bottom of the pad 151 from contacting the top of the square steel pipe. When the driving cylinder 431 drives the push plate 433 to move through the telescopic column 432, the pad 151 located on the top of the lifting screw plate 43 is not squeezed by other pads 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, thereby causing the first spring 311 to drive the extension cylinder 312 to the fixed position. The inner portion of the cylinder 31 slides, and the extension cylinder 312 drives the second roller 321 to move out of the interior of the pad 151 and the pad 152 through the moving frame 32. Therefore, when the push plate 433 drives the pad 151 to move, the second roller 321 will contact the top of the square steel pipe, thereby preventing the pad 151 and the pad 152 from directly contacting the surface of the square steel pipe. It is necessary to prevent gaps from being generated between the square 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 52 to rotate through the worm gear 521, and the second screw 52 drives the moving screw block 522 to move during the rotation.The moving screw block 522 drives the gap plate 533 to move via the receiving block 53 and the extending block 532. As the gap plate 533 moves, the gap plate 533 pushes the square steel tube to move, thereby eliminating the gaps between the multiple square steel tubes. Therefore, during the movement of the backing plate 151, the backing plate 151 will not come into contact with the surface of the square steel tube due to the existence of the gap.

[0077] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0078] Parallel: The parallel defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, allowing for situations where the two sides are not absolutely parallel due to factors such as assembly tolerance, design tolerance, and the influence of structural flatness. Small angle errors are allowed. For example, within an assembly error range of 10 degrees, it can be understood as a parallel relationship.

[0079] Vertical: The vertical defined in this application is not limited to an absolute vertical intersection relationship (angle of 90 degrees). It allows for non-absolute vertical intersection relationships caused by factors such as assembly tolerance, design tolerance, and structural flatness. It allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.
