Description

TECHNICAL FIELD

[0001] The present application is a transportation or storage device, and relates to the field of stereoscopic storage technology, and more particularly to an angle steel tower angle steel intelligent storage system. BACKGROUND

[0002] The angle steel tower angle steel is a core steel component for manufacturing an angle steel tower, also commonly known as angle iron, belongs to the category of hot-rolled steel, is mainly made of low-carbon steel or low-alloy steel through rolling processing, has an L-shaped cross section, and is divided into two specifications of equilateral angle steel and unequal angle steel. The angle steel tower angle steel is combined through welding, bolt connection and other processes to form key structural parts of the tower body, cross arm and inclined brace of the angle steel tower, has excellent bending, shearing and compressive mechanical properties, can effectively bear various forces such as wind load, ice and snow load, equipment dead weight and external construction load, and has the characteristics of light weight, convenient processing and installation, and relatively low material cost, thereby becoming the core material of angle steel tower structures such as power transmission line towers, communication base station towers, radio and television towers and lightning protection towers, and is widely used in the field of infrastructure construction of power, communication, radio and television and other fields.

[0003] At present, there are mainly two ways for the storage of angle steel. The first way is to directly place the angle steel on the ground of the factory building. Although this operation is simple, the angle steel is prone to rust due to ground moisture erosion, and a large area of the ground needs to be leveled, resulting in low space utilization. The second way is to use a special angle steel shelf or a stackable steel rack. The angle steel is classified by specifications and horizontally stacked. The stacked angle steel is placed by using a forklift or a crane. This way significantly improves the space utilization and effectively prevents moisture and rust, and is the mainstream choice of modern storage.

[0004] However, for long angle steel (length ≥ 6 meters), during the process of moving the stacked long angle steel to the storage steel rack, if a forklift is used for transfer, the effective support length of the forklift fork is much smaller than the length of the long angle steel, and only the local area of the long angle steel can be supported, which is prone to permanent bending deformation of the long angle steel due to its own weight. In addition, when the forklift is operating, the two ends of the long angle steel will swing greatly with the movement of the vehicle body, which not only easily causes damage to the surface of the angle steel by colliding with surrounding facilities such as storage steel racks and walls, but also poses a safety risk of hitting the operator. If a crane or gantry crane is used for transfer, although the vertical lifting and large-scale moving of the long angle steel can be achieved, the operation range of such equipment is strictly limited by the lifting track in the factory building, and cannot cover all the steel rack points in the storage area, which has poor flexibility. In addition, the long angle steel is prone to swinging like a pendulum during lifting, which may cause collision and damage, and it is difficult to accurately align with the support slots of the storage steel rack, which prolongs the operation time of the transfer and increases the risk of imbalance and sliding of the stacked body. SUMMARY

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention realizes automated loading and unloading operations for pallet racks with long angle steel by setting a fixed slot steel frame, a moving slot steel frame, a limit frame, a first reinforcing rib, a first screw rod, a first nut seat, a connecting block, a second screw rod, a second nut seat, a slide, a connecting piece, a locking bolt, a first motor, a universal self-locking wheel, a cylinder, a first direction conveying mechanism and a second direction conveying mechanism. By utilizing the cooperation between the moving frame, the conveying roller, the lifting frame and the conveying wheel, it effectively avoids collision damage and personnel safety hazards caused by the downward deformation of the middle part of the long angle steel and the swinging of both ends due to insufficient support length of the forks during forklift transfer. At the same time, it prevents the problem of plastic deformation of the angle steel caused by local support, and ensures that the long angle steel remains stable and does not swing during the transfer process, eliminating collision and safety risks. To address the issues of limited operating range of gantry cranes / gantry cranes due to rail limitations, angle steel twisting caused by lifting point positioning deviations, difficulty in precise alignment during lifting and swaying, and complex dual-machine lifting operations, this application utilizes a folding conveyor mechanism with a precise docking design with the storage rack. It eliminates the need for lifting rails and achieves precise displacement of the pallet rack through screw drive and hydraulic pushing, avoiding the risk of angle steel twisting and stack imbalance and slippage caused by uneven lifting points. This ensures the structural integrity of the long angle steel while improving the safety and efficiency of loading and unloading operations.

[0017] (2) The present invention achieves an integrated design of folding conveyor mechanism and storage rack by setting storage rack, fixed slot steel frame, limiting slot, moving slot steel frame, limiting frame, first reinforcing rib, universal self-locking wheel and cylinder, which greatly improves the utilization rate of space. The cylinder drives the moving slot steel frame and fixed slot steel frame to separate and unfold to achieve the switching of operation state. When not in operation, the moving slot steel frame can be closed and retracted with the fixed slot steel frame. With the cooperation of connecting block, slide, connecting piece, threaded hole and locking bolt, the bidirectional conveyor can be rotated from horizontal state to vertical state and stored synchronously. Combined with the movement and locking function of universal self-locking wheel at the lower end of moving slot steel frame, the entire folding conveyor mechanism can be retracted from the warehouse aisle area, avoiding the problem of traditional transfer equipment occupying aisle space for a long time. Simultaneously, under the action of the first direction conveying mechanism, the second direction conveying mechanism, the first motor, the first lead screw, the second lead screw, the mounting frame, the fifth motor, the third lead screw, and the hydraulic cylinder, the pallet rack can be stored in layers in the vertical space of the storage rack. Compared with the traditional ground stacking or simple steel frame storage mode, it greatly improves the vertical utilization rate of the storage space and solves the space waste problem caused by the large area and insufficient layer height utilization of long angle steel storage.

[0018] (3) The present invention realizes a bidirectional transmission design for receiving and transferring by the first direction transmission mechanism for transmitting along the width direction of the angle steel and the second direction transmission mechanism for transmitting along the length direction of the angle steel. This greatly improves the adaptability to subsequent production lines and transfer equipment. The transmission mode can be flexibly switched according to the transportation direction of the subsequent transfer equipment. There is no need to add additional turning equipment or manually adjust the angle steel placement direction, which reduces the operation steps and equipment investment in the transfer process. On the other hand, the height of the mobile frame can be adjusted by the first motor driving the first lead screw and the second lead screw, so that the pallet frame can be horizontally connected with the assembly line and transfer equipment at different heights, so as to seamlessly connect the long angle steel storage and transfer with the subsequent processing and transportation links, effectively improving the overall operation efficiency of long angle steel from storage to transfer, and enhancing the versatility and adaptability of the equipment.

[0022] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Example 1, please refer to the appendix for details. Figures 1-15As shown, an intelligent storage system for angle steel towers includes multiple sets of linearly arranged intelligent storage devices at equal intervals. Each set of intelligent storage devices includes a mounting frame 1 and storage shelves 2 located on both sides of the mounting frame 1. Each storage shelf 2 has a folding conveyor mechanism 3 on one side. Each folding conveyor mechanism 3 includes four channel steel frames. The four channel steel frames are movably connected to a bidirectional conveyor platform, which can drive a pallet frame 4 containing angle steel to move up and down within the channel steel frames. The bidirectional conveyor platform includes a first-direction conveyor mechanism 5 and a second-direction conveyor mechanism 6. The first-direction conveyor mechanism 5 includes a moving frame 51 and two cover plates 53. The upper side of the moving frame 51 is provided with two mounting slots 511, and the cover plate 53 covers the mounting slots 511. The inner side of the moving frame 51 is provided with multiple conveying rollers 52, and the conveying rollers 52 are divided into two groups. The second direction conveying mechanism 6 is located between the two groups of conveying rollers 52. The second direction conveying mechanism 6 includes a lifting frame 61. Both ends of the lifting frame 61 are provided with guide blocks 611 with rollers. The guide blocks 611 slide up and down in the notch of the lifting frame 61. Multiple rotating shafts 62 are linearly arranged at equal intervals inside the lifting frame 61, and each pair of adjacent rotating shafts 62 are connected by a pulley and a belt. Each rotating shaft 62 is provided with two conveying wheels 621.

[0026] The above structure enables automated loading and unloading of pallet racks containing long angle steel. This avoids the problems of angle steel deformation and collision caused by forklift transportation, and solves the defects of gantry crane / gantry crane operation restrictions and positioning difficulties. It ensures the integrity of the angle steel structure and improves operation safety and efficiency. Its folding design can be folded up and stored to reduce aisle occupation, and it can also be stored in layers to improve the utilization rate of warehouse space. The bidirectional transmission and height adjustment functions can be flexibly adapted to subsequent transfer equipment, seamlessly connected, and improve overall operation efficiency and equipment versatility.

[0027] The specific operation is as follows: When it is necessary to remove the pallet rack 4 containing long angle steel from the storage rack 2, first open the cylinder 39, and then push the corresponding moving slot steel frame 32 to move, so that the moving slot steel frame 32 separates and unfolds from the fixed slot steel frame 31 until one end of the limit frame 321 slides to the top of the limit slot 311. At this time, the limit frame 321 is in a horizontal state, and the bidirectional conveyor also rotates from the vertical direction to the horizontal direction. The connecting piece 361 of the bidirectional conveyor is just moved to the top of the corresponding slide 36. Then tighten the locking bolt 363 on the slide 36 so that the locking bolt 363 passes through the round hole on the inner shaft of the connecting piece 361, thereby achieving the positioning of the height and rotation range of the connecting piece 361. Then, lock the universal self-locking wheel 38 at the lower end of each moving slot steel frame 32. Then, the fifth motor 11 is turned on, driving the third lead screw 12 to rotate. Subsequently, the fourth nut seat 121 on the third lead screw 12 moves the hydraulic cylinder 13 to the corresponding shelf height of the storage shelf 2 through the bracket. Then, the output end of the hydraulic cylinder 13 pushes the pallet rack 4 in the corresponding shelf height, causing the pallet rack 4 to move towards the folding conveyor mechanism 3. The pallet rack 4 gradually approaches the moving frame 51. Then, the second motor 54 in the mounting slot 511 of the moving frame 51 starts, driving the first gear 541 to drive the second gear 542 to rotate. Since the second gear 542 is mounted on a conveyor roller 52, and the conveyor rollers 52 are connected by the mutual cooperation between the pulley and the belt, multiple conveyor rollers 52 rotate simultaneously to move the pallet rack 4 to the middle position of the moving frame 51. Then the first motor 37 is turned on. With the cooperation of the pulley and belt, the first lead screw 33 and the second lead screw 35 rotate, and drive the moving frame 51 through the first nut seat 331 and the second nut seat 351, changing the height of the moving frame 51 so that the pallet frame 4 on the moving frame 51 can be consistent with the height of the assembly line or other transportation equipment, which facilitates subsequent transfer. After determining the height, depending on the transport direction of the assembly line or other equipment, the pallet frame 4 can be moved by the conveyor roller 52 (i.e., along the width direction of the angle steel), or the transport direction of the pallet frame 4 can be changed by the second direction conveyor mechanism 6 (i.e., along the length direction of the angle steel). If it is necessary to move it out along the length direction of the angle steel, the fourth motor 65 drives the positive and negative double threaded screw 66 to rotate. As a result, the third nut seats 661 in the two different thread sections on the positive and negative double threaded screw 66 approach each other, and the push block 662 contacts and squeezes the rollers in the guide blocks 611 at both ends of the lifting frame 61. The pressure causes the lifting frame 61 to move upward, so that the upper edge of the conveyor wheel 621 on the lifting frame 61 is slightly higher than the upper edge of the conveyor roller 52 (at this time, the conveyor roller 52 does not contact the lower side of the pallet frame 4). The upper edge of the conveyor wheel 621 contacts the lower side of the pallet frame 4. Then the fourth motor 65 starts, and through the cooperation between the third gear 641, the fourth gear 642, the corresponding pulleys and belts, it drives multiple rotating shafts 62 to rotate synchronously. Subsequently, the rotating shafts 62 drive the conveyor wheel 621 to rotate, and the pallet frame 4 can be moved to move the long angle steel on the pallet frame 4 to the subsequent transfer equipment. In addition, when receiving the long angle steel on the storage pallet rack 4, the operation can be reversed. By using the folding conveyor mechanism 3, the pallet rack 4 can be moved to the corresponding shelf height of the storage shelf 2 for storage.

[0028] Example 2, please refer to the appendix for details. Figures 4-7As shown, the four channel steel frames are divided into two fixed channel steel frames 31 and two movable channel steel frames 32. The fixed channel steel frames 31 are connected to the storage rack 2 by bolts. Two first reinforcing ribs 322 are welded between the two movable channel steel frames 32, and the two first reinforcing ribs 322 are located on the upper and lower sides of the movable channel steel frames 32 respectively. Each of the two fixed channel steel frames 31 is provided with a first lead screw 33 and a first nut seat 331 on the first lead screw 33. The upper and lower ends of the two first lead screws 33 are connected to a belt by pulleys. Each first nut seat 331 is provided with a connecting block 34. Each of the two movable channel steel frames 32 is provided with a second lead screw 35 and a second nut seat on the second lead screw 35. 351, the upper and lower ends of the two second lead screws 35 are also connected to the belt through pulleys. Each second nut seat 351 is provided with a sliding groove 36 and a connecting piece 361 that slides through the sliding groove 36. The two connecting pieces 361 and the two connecting blocks 34 are hinged to the moving frame 51. Through the mutual cooperation between the first lead screw 33, the first nut seat 331, the second lead screw 35, the second nut seat 351, the connecting block 34 and the connecting piece 361, the moving frame 51 can be driven to rise and fall. It also satisfies the requirement that the moving frame 51 can deflect around the shaft on the connecting block 34 as the center during the unfolding or closing of the fixed slot steel frame 31 and the moving slot steel frame 32. Each of the moving slot steel frames 32 has multiple limit frames 321 hinged at equal intervals on one side of its outer wall. The front end of each limit frame 321 is movably connected to a limit groove 311, which is located on the outer wall of the corresponding fixed slot steel frame 31. The cooperation between the limit groove 311 and the limit frame 321 improves stability during the unfolding or retraction of the slot steel frame. Each moving slot steel frame 32 has a universal self-locking wheel 38 at its bottom. Each fixed slot steel frame 31 has a cylinder 39 mounted on its lower outer wall via a bracket, with the output end of the cylinder 39 connected to one side of the outer wall of the moving slot steel frame 32. The cylinder 39 provides the driving force for the movement of the moving slot steel frame 32. A single moving slot steel frame 32 and... Each of the top ends of the fixed-slot steel frame 31 is equipped with a first motor 37. The output ends of the two first motors 37 are connected to the upper ends of the first lead screw 33 and the second lead screw 35, respectively. The first motors 37 provide driving force for the rotation of the first lead screw 33. A threaded hole 362 is provided on one side of the outer wall of the slide groove 36. A locking bolt 363 is threadedly connected to the threaded hole 362. The front end of the locking bolt 363 passes through the shaft on the connector 361 and positions the connector 361. The locking bolt 363 positions the height of the connector 361 in the slide groove 36. At the same time, since the locking bolt 363 passes through the shaft in the connector 361, it positions the rotation amplitude and ensures the stability of the connection.

[0029] Example 3, please refer to the appendix for details. Figure 3 and attachedFigures 9-15 As shown, both ends of each conveyor roller 52 pass through corresponding circular holes on the inner wall of the movable frame 51 and extend into the mounting groove 511. The ends of every two adjacent conveyor rollers 52 within the mounting groove 511 are connected by pulleys and belt drives to achieve synchronous rotation of each conveyor roller 52. A second motor 54 is installed in one of the mounting grooves 511. A first gear 541 is installed at the output end of the second motor 54. The first gear 541 meshes with a second gear 542, and the second gear 542 is fitted onto one end of the corresponding conveyor roller 52. Two positioning frames 512 are installed in each mounting groove 511, and the two positioning frames 512 are positioned along... The mounting slots 511 are arranged linearly along their length. Multiple second reinforcing ribs 63 are provided on the inner wall of the lifting frame 61 along its length, and the second reinforcing ribs 63 are linearly distributed at equal intervals. One of the second reinforcing ribs 63 is bolted to a U-shaped frame 631. A third motor 64 is provided on the U-shaped frame 631. A third gear 641 is provided at the output end of the third motor 64. The third gear 641 is meshed with a fourth gear 642. The fourth gear 642 is provided on the corresponding rotating shaft 62. Through the mutual cooperation between the third motor 64, the third gear 641 and the fourth gear 642, the driving force for the rotation of the rotating shaft 62 is realized. Each of the mounting slots 511 is equipped with a fourth motor 65, and each of the fourth motors 65 has a double-threaded screw 66 at its output end. The double-threaded screw 66 is mounted on the corresponding positioning frame 512. Each of the two threaded sections on the double-threaded screw 66 has a third nut seat 661. Each third nut seat 661 is bolted to a push block 662. The push block 662 is movably connected to the roller on the corresponding guide block 611. Through the cooperation between the fourth motor 65, the double-threaded screw 66, the third nut seat 661 and the push block 662, the inclined surface on the push block 662 provides an upward component force to the guide block 611, thereby raising the lifting frame 61. The upper side of the mounting frame 1 is bolted to a fifth motor 11. The output end of the fifth motor 11 is provided with a third lead screw 12 and a fourth nut seat 121 on the third lead screw 12. The lower end of the third lead screw 12 is movably connected to a round hole on the lower side of the mounting frame 1. The fourth nut seat 121 is bolted to a hydraulic cylinder 13. The hydraulic cylinder 13 is an alternating telescopic double-rod cylinder that can alternately extend to push the pallet racks 4 in the two storage shelves 2. When the piston in the hydraulic cylinder 13 is centered, the two output ends move in the vertical direction without interfering with the storage shelves 2. Through the cooperation between the fifth motor 11, the third lead screw 12, the fourth nut seat 121 and the hydraulic cylinder 13, the pallet racks 4 in the storage shelves 2 are pushed to one side of the folding conveyor mechanism 3.
