Description

Technical Field

[0001] This invention relates to the technical field of concrete components, specifically to an intelligent reinforcement binding and automatic skeleton forming system for concrete components. Background Technology

[0002] As the core component of building structure, the production quality and efficiency of concrete components directly determine the safety and progress of the project. As the "skeleton" of concrete components, the steel reinforcement cage plays a key role in load transfer and structural reinforcement. Its binding accuracy and forming efficiency have become the core bottlenecks restricting the standardization and large-scale production of components.

[0003] Traditional rebar mesh binding relies on manual operation, which has many unavoidable drawbacks: low efficiency, manual binding requires fixing the cross-sections of rebars point by point, and binding a single rebar can take several minutes. For complex mesh formation, multiple workers are often needed to work together, making it difficult to meet the mass production requirements of prefabricated buildings. To solve these problems, a binding robot and binding method for facade rebar mesh disclosed in Chinese Patent Application No. CN202310366647.5 (application date 2023-04-07) can be referenced. This binding mechanism can drive the binding wire through the rebar nodes of the facade rebar mesh and drive the binding... The system includes a wire-binding rebar node; a positioning mechanism connected to the binding mechanism, which can move the binding mechanism to any rebar node within the binding range corresponding to the vertical rebar mesh; and a walking mechanism connected to the positioning mechanism, which can be connected to the vertical rebar mesh and move up and down and left and right on the vertical rebar mesh. Reference can also be made to a prior art patent (Chinese Patent Application No. CN202211379914.4, filed on 2022-11-04) that discloses an intelligent rebar binding robot capable of moving on a rebar mesh. This intelligent rebar binding robot capable of moving on a rebar mesh has a simple structure, reliable operation, and autonomous... This device is mobile and can automatically identify the binding position and perform the binding operation, thereby automating the binding process. Refer to the prior art patent (Chinese patent application number CN202411198206.X, application date 2024-08-29) which discloses a rebar binding device and method. Through the operation of cylinder four, the limiting plate at one end is pushed to adjust its angle, thereby clamping the clamping blocks on both sides together to hold the rebar together. Simultaneously, the operation of cylinder three on one side pushes the pressing plate on one side to move, pushing the binding strap to the inside of the clamping blocks, causing the binding strap to fall into the inner side of the two clamping blocks. At the same time, the brake motor four on one side operates, driving the guide on one side... The wheel rotates, causing the binding strap to move inside the clamping block and come into contact with the surface of the rebar bundle. After the binding strap is in place, the upper cylinder two moves upward while the lower cylinder four retracts, causing the two clamping blocks to open outward, detaching them from the rebar and bringing the binding strap into contact with the outer side of the rebar. When the clamping blocks detach from the rebar as a whole, cylinder four pushes the two clamping blocks together again, clamping the binding strap together. After completion, the upper brake motor three rotates, clamping the binding strap connection point, thus automatically binding the rebar, reducing manual operation and effectively minimizing the risk of injury from manual operation.

[0004] Although the above-mentioned device can reduce manual operation, it still has some shortcomings in use. For example, when binding and shaping a square frame, the frame is placed vertically, and the high position makes it inconvenient for workers to bind it.

[0005] Therefore, we proposed an intelligent reinforcement binding and automatic skeleton forming system for concrete components to solve the problems mentioned above. Summary of the Invention

[0011] Preferably, the movable cylinder, the adjusting cylinder, and the receiving square cylinder are all hollow structures. The upper inner side of the movable cylinder is threadedly connected to the threaded rotating rod, and the other end of the threaded rotating rod is rotatably supported on the inner back wall of the adjusting cylinder.

[0012] Preferably, the crawling mechanism includes a rotating mechanism communicating with one side of the fixed cylinder and a telescopic mechanism connected to the outside of the fixed cylinder. The rotating mechanism acts on one side of the two sets of limiting blocks to drive them to open and close. The telescopic mechanism is symmetrically arranged in two sets about the transverse centerline of the moving frame.

[0013] Preferably, the rotating mechanism includes a square groove inside the fixed cylinder, a piston block slidably disposed within the square groove, one end of the piston block being connected to the side wall of the fixed cylinder via a return spring, the return spring being sleeved on the outside of the rotating worm, the inner side of the piston block away from the return spring having an internal thread that helically engages with one end of the rotating worm, a connecting worm wheel meshing with the outer side of the rotating worm, a rotating gear fixed at the center of the connecting worm wheel, a connecting tooth block meshing with the outer side of the rotating gear, one end of the connecting tooth block being fixed to one side of a limiting block, and the limiting block being slidably disposed within a slide rail on one side of the adjusting cylinder.

[0014] Preferably, both ends of the rotating worm, the connecting worm wheel, and the rotating gear are rotatably supported on the inner wall of the adjusting cylinder by bearings, the two sets of limiting blocks move in opposite directions, and one side of the limiting block is provided with a through hole for the connecting tooth block to be inserted and slid.

[0015] Preferably, the telescopic mechanism includes a mating hose that communicates with one end of the fixed cylinder near the delivery hose.

[0019] 1. The position adjustment component allows for quick adjustment of the adjusting cylinder to fit the outer side of precast concrete components of different sizes, solving the problem of tedious manual fitting; the hydraulic conveying component drives the limiting block to achieve initial limiting fit, and the climbing mode of alternating relaxation, adjustment, clamping and retraction of the upper and lower limiting blocks can stably fit the surface of the component, providing stable support for multi-directional binding of rebar tying machines, avoiding deviations caused by manual support or moving of equipment, and improving the accuracy of binding position.

[0020] 2. Significantly improves operational safety and automation continuity. The hydraulic conveying component coordinates the clamping and movement of the crawling mechanism, eliminating the need for manual climbing to heights for binding operations and fundamentally avoiding the risks of working at heights. The position adjustment component is driven by a combination of electric push rod and threaded rotating rod to achieve automated adjustment from horizontal to vertical, eliminating the need for manual adjustment of the fitting components. The overall process reduces manual intervention, which not only reduces labor intensity but also avoids human error. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9 The present invention provides the following technical solution: intelligent reinforcement binding and automatic skeleton forming system for concrete components.

[0033] Example 1: To facilitate the binding of square or round frames, please refer to the attached document. Figure 1 -Appendix Figure 4 The system includes a movable frame 1, with two sets of rebar tying machines 6 movably connected to the top of the frame 1. The bottom of the rebar tying machines 6 is rotatably mounted on the top edge of a turntable 4, and the bottom of the turntable 4 is rotatably mounted inside the movable frame 1. A rotating mechanism is located below the rebar tying machines 6, and the top of the rotating mechanism is rotatably connected to the rebar tying machines 6 to enable multi-angle tying operations. Electric push rods 7 are installed at all four corners of the movable frame 1. The output end of the electric push rods 7 is connected to a position adjustment component to adapt to the initial fit of concrete components of different sizes. A hydraulic conveying component 12 is installed on the top of the device. The inlet and outlet of the hydraulic conveying component 12 are connected to the fixed cylinder 14 through the conveying hose 13. The rotating mechanism includes a drive motor 2 installed on the movable frame 1. The output end of the drive motor 2 is fixedly connected to the center of the contact roller 3. The outer side of the contact roller 3 is in frictional contact with the outer side of the turntable 4. Several sets of guide blocks 5 are fixed at the bottom of the turntable 4. The guide blocks 5 are slidably arranged in the top slide rail of the movable frame 1. Both ends of the movable frame 1 and the turntable 4 along the axial direction are through-type for placing concrete components.

[0034] The system is first placed on the outside of a square or round concrete component. Utilizing the through-type design of the moving frame 1 and the turntable 4 along the axial direction, the component is smoothly placed inside the equipment. The electric push rod 7 is activated, and its output end drives the position adjustment component to move, so that the adjustment cylinder 11 quickly fits against the outside of the component, adapting to the initial positioning requirements of components of different sizes. During the binding operation, the drive motor 2 starts and drives the fitting roller 3 to rotate. With the frictional cooperation between the fitting roller 3 and the turntable 4, the turntable 4 is driven to rotate inside the moving frame 1. The guide block 5 at the bottom of the turntable 4 slides along the top slide rail of the moving frame 1, constraining the movement trajectory of the turntable 4 to ensure stability. The two sets of rebar binding machines 6 at the top edge of the turntable 4 rotate with the turntable 4. At the same time, they can adjust their angle through the bottom rotating structure to achieve binding of components in different positions. During this process, the hydraulic conveying component 12 at the top of the moving frame 1 delivers hydraulic power to the fixed cylinder 14 through the conveying hose 13, providing a basis for the subsequent fitting and limiting of the limiting block 21, further ensuring the stability of the binding process.

[0035] Example 2: To address the issue that current binding machines on the market, when binding square frames, present a problem where the vertically placed frame is inconvenient for workers to perform binding operations at a high position, the following solution can be referenced. Figure 1 Appendix Figure 2 and attached Figure 5 -Appendix Figure 9The position adjustment component includes a slider 8 fixedly connected to the output end of the electric push rod 7. The slider 8 is slidably disposed in a horizontal groove at the top of the movable frame 1. A receiving square tube 9 is fixed to both the upper and lower ends of the slider 8. A movable tube 10 is slidably fitted onto the outer side of the receiving square tube 9. The upper end of the movable tube 10 is slidably disposed inside the adjusting tube 11. The movable tube 10, adjusting tube 11, and receiving square tube 9 are all hollow structures. The inner side of the upper end of the movable tube 10 is threadedly connected to a threaded rotating rod 25. The other end of the threaded rotating rod 25 is rotatably supported on the inner wall of the back of the adjusting tube 11. A crawling mechanism is connected to the inner side of the fixed tube 14. The outer side of the mechanism acts on the surface of the concrete component to achieve overall crawling; the crawling mechanism includes a rotating mechanism connected to one side of the fixed cylinder 14 and a telescopic mechanism connected to the outer side of the fixed cylinder 14. The rotating mechanism acts on one side of two sets of limiting blocks 21 to drive them to open and close. Two sets of telescopic mechanisms are symmetrically arranged about the transverse centerline of the moving frame 1. The rotating mechanism includes a square groove opened inside the fixed cylinder 14. A piston block 16 is slidably arranged in the square groove. One end of the piston block 16 is connected to the side wall of the fixed cylinder 14 through a return spring 15. The return spring 15 is sleeved on the outer side of the rotating worm gear 17. The inner side of the end of the plug block 16 away from the return spring 15 has an internal thread that screws into one end of the rotating worm 17. A connecting worm wheel 18 is meshed with the outer side of the rotating worm 17. A rotating gear 19 is fixed at the center of the connecting worm wheel 18. A connecting tooth block 20 is meshed with the outer side of the rotating gear 19. One end of the connecting tooth block 20 is fixed to one side of the limiting block 21. The limiting block 21 is slidably disposed in a slide rail on one side of the adjusting cylinder 11. Both ends of the rotating worm 17, the connecting worm wheel 18, and the rotating gear 19 are rotatably supported on the inner wall of the adjusting cylinder 11 by bearings. The two sets of limiting blocks 21 move in the direction of... On the opposite side, a through hole is provided on one side of the limiting block 21 for the connecting tooth block 20 to be inserted and slid; the telescopic mechanism includes a mating hose 22 that is connected to one end of the fixed cylinder 14 near the conveying hose 13. The two ends of the mating hose 22 are respectively sealed to the bottom side of the fixed cylinder 14 and the receiving square cylinder 9. The inside of the receiving square cylinder 9 is connected to the bottom surface of the piston disc 23 through the connecting spring 24; a rubber ring is also nested on the outside of the piston disc 23, and the outside of the rubber ring is fitted against the inner wall of the receiving square cylinder 9; a two-way pressure valve is provided inside the mating hose 22, and the pressure threshold of the two-way pressure valve is greater than the elastic force of the return spring 15.

[0036] In the initial positioning stage, the electric push rod 7 is activated, and its output end drives the slider 8 to slide along the horizontal groove at the top of the moving frame 1, causing the receiving square cylinder 9, the moving cylinder 10, and the adjusting cylinder 11 to move horizontally. The threaded rotating rod 25 is rotated, and because the inner side of the upper end of the moving cylinder 10 is threaded into it, the moving cylinder 10 slides vertically along the outer side of the receiving square cylinder 9 and the inside of the adjusting cylinder 11, ultimately allowing the adjusting cylinder 11 to precisely fit the outer side of the square frame, adapting to components of different sizes. During the limiting and fixing stage, the hydraulic conveying component 12 delivers hydraulic oil to the fixed cylinder 14 through the conveying hose 13, pushing the piston block 16 in the square groove to compress the return spring 15 and slide. Because the piston block 16 is helically engaged with the rotating worm gear 17, it drives the rotating worm gear 17 to rotate, thereby meshing and driving the connecting worm wheel 18 and the coaxial rotating gear 19 to rotate. The rotating gear 19 drives the connecting tooth blocks 20 on both sides to slide along the through holes of the limiting blocks 21, causing the two sets of opposing moving limiting blocks 21 to move closer along the slide rail of the adjusting cylinder 11, clamping the frame and realizing the equipment... When the device is fixed, the pressure threshold of the two-way pressure valve inside the hose 22 is greater than the elastic force of the return spring 15, ensuring that the rotating mechanism operates first. During the binding operation, after the rebar binding machine 6 completes the binding at the current height, it starts the crawling process. First, the upper fixed cylinder 14 is depressurized, and the return spring 15 rebounds, causing the piston block 16 and the rotating worm gear 17 to move in the opposite direction, and the limit block 21 is released. The hydraulic oil enters the receiving cylinder 9 through the hose 22, pushing the piston disc 23 with the rubber ring to compress the connecting spring 24, causing the moving cylinder 10 and the adjusting cylinder 11 to rise to a new height, and the upper limit block 21 clamps again. Then, the lower fixed cylinder 14 is depressurized, the lower limit block 21 is released, and the hydraulic oil flows back, causing the lower adjusting cylinder 11 to contract, and then clamps the lower end. By alternately releasing, raising, lowering, clamping, and moving the upper and lower limit blocks 21, the equipment can climb along the skeleton autonomously. In conjunction with the rebar binding machine 6 (which is existing technology and will not be described in detail), the high-altitude binding is completed.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
