Description

Technical Field

[0001] This invention belongs to the field of precast steel reinforcement cage technology, specifically a precast steel reinforcement cage device for concrete components. Background Technology

[0002] In building construction, the construction quality of core components such as concrete columns and beams directly determines the overall structural stability and service life of the building. As the core load-bearing structure of concrete components, the precision of prefabrication and the overall stability of the steel reinforcement cage are crucial to ensuring the construction quality of the components.

[0003] The reinforcement cages for most concrete components still rely on traditional manual splicing and tying methods, resulting in a relatively conventional work process. According to authorization announcement number CN113250066A, a reinforcement positioning device for precast box-type beam reinforcement cage fabrication includes a base and an internally threaded cylinder. A base is fixedly connected to the base, and a workbench is fixedly connected above the base. A template is fixedly connected above the internally threaded cylinder. A groove is formed in the workbench, and a bidirectional threaded rod is fixedly connected within the groove. A second pulley is sleeved inside the lower end of a conveyor belt. The internally threaded cylinder is threadedly connected to the bidirectional threaded rod. A first sliding plate is fixedly connected to one side of the internally threaded cylinder, and the first sliding plate is slidably connected within a first slide rail. The first slide rail is fixedly connected to the inner wall of the groove. This reinforcement positioning device for precast box-type beam reinforcement cage fabrication is equipped with a start-up drive motor. The drive motor rotates one end of the bidirectional threaded rod, causing the internally threaded cylinder to move within the groove following the bidirectional threaded rod, thereby adjusting the position of the two sets of templates and thus the position of the reinforcement, facilitating positioning.

[0004] Currently, the traditional construction methods for fabricating steel reinforcement cages for large concrete components such as columns and beams rely heavily on manual labor, making it impossible for a single person to complete the entire binding operation. The steel reinforcement cages for these components contain multiple long bars, which are heavy and long, making their placement and positioning difficult. The process of lapping and forming requires the cooperation of multiple people to complete the basic framework construction. Summary of the Invention

[0008] Preferably, a number of lifting components are arranged side by side on the upper end of the base platform. Each lifting component includes two symmetrically distributed servo hydraulic cylinders. The lower end of the servo hydraulic cylinder is fixed to the surface of the base platform. The servo hydraulic cylinder is provided with a piston rod for extension and retraction, and a lifting plate is fixedly installed at the end of the piston rod.

[0009] Preferably, the surface of the platform has a plurality of internal holes that penetrate through it, the surface of the lifting plate slides through the internal holes, and a roller frame is mounted on the upper end of the lifting plate, on which a conveying roller is rotatably mounted via a roller shaft.

[0010] Preferably, the slide has an E-shaped structure, with a threaded ring fixed through the lower end of the slide. A threaded knob is installed inside the threaded ring, and the inward end of the threaded knob is tightly abutted against the surface of the table.

[0011] Preferably, a wheel frame is symmetrically installed at the middle of the slide block along the upper and lower positions, and a guide wheel is rotatably installed on the wheel frame via a wheel axle. The surface of the guide wheel is slidably and tightly attached to the inner wall of the slide groove.

[0012] Preferably, a positioning frame is fixedly installed on the upper end of the two slide blocks, and threaded rods are symmetrically fixed on both sides of the positioning frame. A lifting sleeve is slidably sleeved on the surface of the threaded rod, and a threaded sleeve is tightly attached to the lower end of the lifting sleeve. The inner wall of the threaded sleeve and the surface of the threaded rod are threaded together.

[0013] Preferably, a square rod is fixedly installed between two lifting sleeves located at the same horizontal position. Several square sleeves are slidably fitted onto the surface of the square rod. A scale ruler is fixedly installed on the surface of the square rod. The inner wall of the square sleeve is slidably and tightly fitted to the surface of the scale ruler. A threaded sleeve is fixedly installed through the lower end of the square sleeve. A threaded knob is installed inside the threaded sleeve. The inward end of the threaded knob is tightly fitted against the surface of the square rod.

The present invention arranges multiple lifting components with servo hydraulic cylinders side by side on the upper part of the base platform, and slides the lifting plate and conveying roller through the built-in hole of the platform. After the steel reinforcement skeleton is tied or welded, the servo hydraulic cylinder pushes the conveying roller upward through the built-in hole and lifts the steel reinforcement skeleton smoothly, thereby using the rolling characteristics of the conveying roller to easily move the heavy skeleton out of the working area. 3. This invention sets a shaft in the center frame and processes two external threads with opposite directions on the shaft surface. With the help of a servo motor drive and the guide constraint of the limiting block by the strip hole, the two limiting plates can move synchronously closer or further away from each other, thereby uniformly clamping or loosening the side of the steel reinforcement skeleton from both sides, and realizing the limiting control of the lateral displacement of the skeleton.

Detailed Implementation

[0020] Example 1 like Figures 1 to 10As shown, the specific embodiment adopts the following technical solution: a prefabrication device for a concrete component steel reinforcement cage, including a prefabrication support mechanism 1, on which erection mechanisms 2 for supporting the two ends of the steel reinforcement are symmetrically distributed, and on the surface of the prefabrication support mechanism 1, a limiting mechanism 3 for preventing the side of the steel reinforcement cage from deviating is also provided. The erection mechanism 2 is used to support the two ends of the main reinforcement of the steel reinforcement cage, and the limiting mechanism 3 is used to limit the side of the steel reinforcement cage to prevent deviating. The prefabricated support mechanism 1 includes a platform 10, which is a flat metal bearing plate that serves as the direct working surface. The erection mechanism 2 includes a slide 20 and a slide block 21. The slide 20 is symmetrically opened on both sides of the platform 10. The slide 20 is a long strip-shaped concave track with precise straightness. The slide block 21 is slidably mounted on the slide 20. The inner side of the slide block 21 is slidably and tightly attached to the surface of the platform 10. The inner side attachment structure can use the surface of the platform 10 as an auxiliary support surface to share the vertical load on the slide block 21 and reduce the unidirectional pressure on the side wall of the slide 20. A scale 22 is symmetrically mounted on the upper end of the platform 10. The slide block 21 and the scale 22 are slidably attached. When the operator moves the slide block 21, the corresponding value of the edge or pointer of the slide block 21 and the scale 22 can be directly read, thereby realizing the precise quantitative adjustment of the distance between the two symmetrical erection mechanisms 2. The limiting mechanism 3 includes a side platform 30 and a central frame 31. The side platform 30 is fixed in the middle of the inner wall of the slide groove 20. The upper ends of the two side platforms 30 are jointly installed with the same central frame 31. A limiting sleeve 3008 is fixed through the side wall of the central frame 31. A limiting rod 3009 is slidably sleeved inside the limiting sleeve 3008. The limiting rod 3009 is a smooth, hard round rod that can slide freely axially within the limiting sleeve 3008. The limiting sleeve 3008 provides it with a precise linear motion trajectory and restricts its radial sway. A limiting plate 3007 is fixedly installed at the inward end of the limiting rod 3009. The limiting plate 3007 is a metal plate with a certain length and thickness, and its working surface is flat and perpendicular to the table surface 10.

[0021] The platform 10 has several symmetrically distributed legs 11 at its lower end. The legs 11 are L-shaped, which increases the contact area with the ground and provides better anti-overturning ability. The bottom of the legs 11 has horizontally opened mounting holes 12 that penetrate through them. The entire device can be firmly anchored to the working ground using anchor bolts through the mounting holes 12, ensuring the overall stability of the device during binding or welding operations and avoiding the impact of shaking on the stability of the frame formation. A base platform 13 is fixedly installed between the legs 11 distributed on both sides. The base platform 13 has a T-shaped cross-section and angle steel 19 is provided on both sides of the base platform 13. The base platform 13 is reinforced and installed with the legs 11 through the angle steel 19. The angle steel 19 serves as a diagonal brace or connector, further connecting the base platform 13 with the legs 11 on both sides to form an integral frame.

[0022] The upper end of the base 13 is provided with several lifting components arranged side by side. Each lifting component contains two symmetrically distributed servo hydraulic cylinders 15. The lower end of the servo hydraulic cylinder 15 is fixed to the surface of the base 13, which provides a stable mounting base for it. The servo hydraulic cylinder 15 is provided with a piston rod for extension and retraction, and the end of the piston rod is fixedly installed with a lifting plate 16. The servo hydraulic cylinder 15 can perform extension and retraction actions in a controlled and precise manner, thereby pushing the lifting plate 16 to rise and fall smoothly.

[0023] The platform 10 has several internal holes 14 that penetrate through it. The surface of the lifting plate 16 slides through the internal holes 14. A roller frame 17 is mounted on the upper end of the lifting plate 16. A conveying roller 18 is mounted on the roller frame 17 via a roller shaft. When the steel reinforcement skeleton is tied or welded, the control system commands the piston rod of the servo hydraulic cylinder 15 to extend synchronously, pushing the lifting plate 16 and the conveying roller 18 upward through the internal holes 14. The top surface of the conveying roller 18 is higher than the platform 10 and contacts the bottom of the steel reinforcement skeleton, lifting it smoothly. At this time, the operator can easily push or use an external traction device to move the heavy steel reinforcement skeleton out of the work area along the length of the platform 10 using the rolling characteristics of the conveying roller 18.

[0024] The slide block 21 has an E-shaped structure with three horizontally extending wing plates. The middle wing plate is embedded in the slide groove 20, while the upper and lower wing plates are located above and below the table surface 10, respectively. This structure can constrain the slide block 21 in multiple directions, preventing it from tilting or derailing, and ensuring smooth sliding and load-bearing capacity. A threaded ring 23 is fixed through the lower end of the slide block 21. A threaded knob 24 is installed inside the threaded ring 23. The inward end of the threaded knob 24 is tightly pressed against the surface of the table surface 10. When the slide block 21 moves to the predetermined position along the slide groove 20, the operator tightens the threaded knob 24 clockwise. Its end presses tightly against the bottom surface of the table surface 10. The self-locking characteristic of the threaded pair generates a huge positive pressure, thereby generating sufficient static friction to firmly lock the slide block 21 onto the table surface 10, preventing it from being accidentally displaced due to vibration or force during subsequent operations.

[0025] Among them, wheel frames 25 are symmetrically installed in the middle of the slide block 21 at the upper and lower positions. Guide wheels 26 are rotatably installed on the wheel frames 25 through wheel axles. The surface of the guide wheels 26 is slidably and tightly attached to the inner wall of the slide groove 20, which transforms the original sliding friction into rolling friction, greatly reducing the resistance when the slide block 21 moves, making the adjustment operation easier and less laborious, and at the same time avoiding wear on the inner wall of the slide groove 20.

[0026] The upper ends of the two slide blocks 21 are fixedly mounted with positioning frames 2001. Threaded rods 2002 are symmetrically fixed on both sides of the positioning frames 2001. A lifting sleeve 2003 is slidably sleeved onto the surface of the threaded rod 2002. A threaded sleeve 2004 is tightly fitted to the lower end of the lifting sleeve 2003. The inner wall of the threaded sleeve 2004 is threaded to the surface of the threaded rod 2002. The inner hole of the lifting sleeve 2003 is clearance-fitted with the outer diameter of the threaded rod 2002, allowing it to slide freely up and down along the threaded rod 2002. When the operator rotates the threaded sleeve 2004, since the threaded rod 2002 is fixed, the threaded sleeve 2004 will move up and down along the axis of the threaded rod 2002, thereby pushing the lifting sleeve 2003 above it to rise and fall synchronously. By precisely controlling the number of rotations of the threaded sleeve 2004, the height position of the lifting sleeve 2003 can be adjusted. Combined with the self-locking characteristics of the thread, the set height can be stably maintained without slipping. At the same time, with the support of the conveyor roller 18, the threaded sleeve 2004 can avoid being subjected to a large downward force.

[0027] A square rod 2006 is fixedly installed between two lifting sleeves 2003 located at the same horizontal position. The cross-section of the square rod 2006 is square. Several square sleeves 2008 are slidably sleeved on the surface of the square rod 2006. The square sleeves 2008 can be moved horizontally along the surface of the square rod 2006. A scale ruler 2007 is fixedly installed on the surface of the square rod 2006. The scale ruler 2007 is arranged along the length of the square rod 2006, and its zero position is usually set at the center or end of the square rod 2006. When sliding the square sleeve 2008, the operator can directly observe the alignment of the side or indicator mark of the square sleeve 2008 with the scale line of the ruler 2007, thereby accurately adjusting the spacing between adjacent square sleeves 2008 and eliminating measurement errors. The ruler 2007 is arranged along the length of the square rod 2006, and its zero position can be set at the center or end of the square rod 2006 according to actual usage requirements. When sliding the square sleeve 2008 along the square rod 2006, the operator can directly read and accurately control the spacing between adjacent square sleeves 2008 by observing the alignment of the side or indicator mark of the square sleeve 2008 with the scale line of the ruler 2007, without the need for additional external measuring tools. The scale structure of this solution integrates scale markings during manufacturing, making the adjustment process of the rebar spacing more intuitive and convenient for workers to pre-set. The inner wall of the square sleeve 2008 slides tightly against the surface of the ruler 2007. The square sleeve 2008 is fixedly connected to a threaded sleeve 2010 at its lower end. A threaded knob 2005 is installed inside the threaded sleeve 2010. The inward end of the threaded knob 2005 is tightly pressed against the surface of the square rod 2006. When the square sleeve 2008 moves to the preset scale position, the operator tightens the threaded knob 2005, causing its end to press against the side of the square rod 2006. Friction force firmly fixes the square sleeve 2008 to the square rod 2006, ensuring that the rebar sleeve 2009 will not move during the binding process. A rebar sleeve 2009 for rebar insertion is also fixedly installed at the upper end of the square sleeve 2008. The rebar sleeve 2009 has a cylindrical structure with an inner diameter slightly larger than the nominal diameter of the main rebar used, facilitating smooth insertion of the rebar end. The rebar sleeve 2009 has a certain height, providing sufficient radial support and guidance for the inserted main rebar end, preventing bending or tilting of the main rebar end under stress.

[0028] The side platform 30 has an internal sleeve 32 fixedly installed inside, and the lower end of the center frame 31 is fixedly installed with a threaded post 33. The surface of the threaded post 33 is slidably fitted with the inside of the internal sleeve 32. The end of the threaded post 33 is threadedly installed with a threaded cap 34. One end of the threaded cap 34 is tightly fitted with the end face of the internal sleeve 32. The center frame 31 spans across the middle of the platform 10 and connects the left and right side platforms 30 to form a gantry structure with a span of the entire width of the platform 10. When it is necessary to install the side platform 30 and the center frame 31, the center frame 31 and the side platform 30 are erected. At this time, the threaded post 33 and the internal sleeve 32 are connected through each other. The threaded cap 34 and the threaded post 33 are threadedly installed to each other, so that the side platform 30 and the center frame 31 can be stably connected.

[0029] The central frame 31 has an inner cavity 3001. The inner walls of the inner cavity 3001 are symmetrically fitted with bushings 3002. The two bushings 3002 are rotatably mounted with shafts 3003. The outer end of the central frame 31 is fixedly mounted with a servo motor 3004 by a bracket. The servo motor 3004 has a rotating shaft for driving. The end of the rotating shaft is connected to the shaft 3003 by a coupling. The servo motor 3004 is externally connected to a forward and reverse switch. After the servo motor 3004 is powered on, it can make the rotating shaft rotate and drive the shaft 3003 to rotate. The shaft 3003 has symmetrically distributed external threads 3010 on its surface. The left half of the shaft 3003 is machined with a right-hand thread, and the right half is machined with a left-hand thread. The two threads have the same lead but opposite directions of rotation. A threaded sleeve 3005 is threaded onto the surface of the external threads 3010. A limit block 3006 is fixedly installed on the outer ring wall of the threaded sleeve 3005. The lower end of the limit block 3006 is fixedly installed with the end of the limit plate 3007. A slotted hole 3011 is formed through the lower end of the inner wall of the inner cavity 3001. The surface of the limit block 3006 slides tightly against the inner wall of the slotted hole 3011. The configuration is as follows: when the shaft 3003 rotates, the limiting block 3006 is stuck in the slotted hole 3011 and cannot rotate with it. This forces the threaded sleeve 3005 to move in a straight line along the external thread 3010. Since the two threads rotate in opposite directions, when the servo motor 3004 drives the shaft 3003 to rotate in one direction, the two threaded sleeves 3005 will drive the limiting block 3006 and the limiting plate 3007 to move closer to each other synchronously along the slotted hole 3011, thereby clamping the side of the steel reinforcement cage. When the shaft 3003 rotates in the opposite direction, the two limiting plates 3007 will move further away from each other synchronously, releasing the cage.

[0030] Example 2 Robotic welding can be adapted for welding steel mesh, as detailed below: In this embodiment, the sliding grooves 20 symmetrically opened on both sides of the platform 10 and the sliding block 21 with scale 22 are used to achieve precise adjustment of the distance between the erection mechanisms 2, ensuring the precise alignment of the support positions at both ends of the steel reinforcement skeleton. This precise alignment mechanism provides a stable positioning foundation for subsequent robot welding, enabling the welding robot to perform automated operations on the predetermined welding nodes without additional adjustment of the workpiece position. A sliding square sleeve 2008 is provided on the square rod 2006, and a scale ruler 2007 is provided. The operator can use this to precisely control the spacing between adjacent steel sleeves 2009, thereby ensuring that the distribution position of the main reinforcement has a high degree of consistency and repeatability. This standardized arrangement method is conducive to the welding robot to identify and weld the intersection of the stirrups and the main reinforcement according to the preset program, reducing manual intervention and improving welding efficiency and quality. The limiting mechanism 3 is driven by the servo motor 3004 to rotate the shaft 3003, which drives the two limiting plates 3007 to clamp the side of the steel reinforcement skeleton in the middle at the same time. This can effectively constrain the positional displacement of the skeleton in the width direction. This limiting action is repeatable and controllable, which can provide a fixed working boundary for the welding robot, avoid welding deviation caused by skeleton movement, and further ensure the feasibility of automated welding. The lifting assembly installed on the upper end of the base platform 13 can push the conveying roller 18 through the built-in hole 14 to smoothly lift the finished frame after the frame is tied or welded. The rolling characteristics of the conveying roller 18 are used to move the frame out of the working area. This unloading method is easy to connect with subsequent automated conveyor lines or robot unloading systems.

[0031] Example 3 The material handling process after the steel reinforcement cage is bound is as follows: The servo hydraulic cylinder 15 on the base is activated, and the piston rod extends synchronously, pushing the lifting plate 16 and the conveying roller 18 through the built-in hole 14 of the platform 10 to lift them upward and support the steel reinforcement skeleton smoothly. Loosen the threaded knob 24 to release the lock between the slide 21 and the table 10. Slide the two slides 21 outward along the slide groove 20 to remove them, so that the frame and the erection mechanism 2 at both ends are completely removed, so as to avoid the erection mechanism 2 from obstructing the horizontal pushing of the frame. With no obstruction at both ends of the frame, the operator can push the frame horizontally along the length of the table 10 and use the rolling characteristics of the conveying roller 18 to easily move the frame out of the working area to complete the material picking. At this time, the limiting mechanism 3 can ensure the protection against excessive deviation on both sides during the frame conveying process.

[0032] The operation of this invention is as follows: First, the operator determines the length of the reinforcing steel cage and the spacing of the main reinforcing bars according to the design drawings. Then, the operator moves the slide block 21 along the symmetrically opened grooves 20 on both sides of the platform 10. The slide block 21 adopts an E-shaped structure, with the middle wing plate embedded inside the groove 20. The upper and lower wing plates are located above and below the platform 10, respectively. Simultaneously, the guide wheel 26 rolls against the inner wall of the groove 20, converting sliding friction into rolling friction, making the movement easy and effortless. During the movement, the operator directly reads the corresponding value between the edge of the slide block 21 and the scale 22 fixed at the upper end of the platform 10, achieving precise quantitative adjustment of the distance between the two symmetrical support mechanisms 2. After reaching the predetermined position, the operator tightens the threaded knob 24 inside the threaded ring 23, causing its end... The part is pressed tightly against the bottom surface of the platform 10. The static friction generated by the self-locking property of the thread pair will firmly lock the slide block 21. Then, the operator rotates the threaded sleeve 2004 on the threaded rod 2002. Since the threaded rod 2002 is fixed, the threaded sleeve 2004 will move up and down along the axis, pushing the lifting sleeve 2003 to rise and fall synchronously, thereby adjusting the erection height of the square rod 2006. Next, the square sleeve 2008 is slid along the square rod 2006. At the same time, the scale line of the second scale 2007 is observed to control the spacing between adjacent steel bar sleeves 2009. The threaded knob 2005 is tightened to fix the square sleeve 2008. Finally, the end of the main bar is inserted into the cylindrical steel bar sleeve 2009 to obtain radial support and guidance, and to prevent the end from bending or tilting. After the two ends of the main rib are fixed by the erection mechanism 2, the operator starts the servo motor 3004 fixed on the outer end bracket of the center frame 31. After the servo motor 3004 is powered on, its rotating shaft drives the shaft 3003 inside the bushing 3002 to rotate through the coupling. The surface of the shaft 3003 is provided with symmetrically distributed external threads 3010. The left half is a right-hand thread and the right half is a left-hand thread. The two sections have the same lead but opposite directions of rotation. When the shaft 3003 rotates, the limiting block 3006 fixed on the outer ring wall of the threaded sleeve 3005 is stuck by the strip hole 3011 opened at the lower end of the inner cavity 3001 and cannot rotate with it. This forces the two threaded sleeves 3005 to move in a straight line along the external threads 3010. With the two threads rotating in opposite directions, the two threaded sleeves 3005 drive the limiting block 3006 and the limiting plate 3007 to move closer to each other along the strip hole 3011, clamping the side of the steel reinforcement skeleton from both sides to the middle. At this time, the limiting rod 3009 slides axially in the limiting sleeve 3008, providing the limiting plate 3007 with a precise linear motion trajectory and limiting radial sway, ensuring that the working surface of the limiting plate 3007 is always perpendicular to the table 10. The entire limiting mechanism 3 is fixed to the inner wall of the slide groove 20 through the side platform 30. The central frame 31 spans the middle of the table 10 to form a gantry structure. When disassembly is required, the threaded cap 34 at the end of the threaded column 33 can be unscrewed to separate the central frame 31 from the side platform 30. After the main reinforcement bar is inserted into the reinforcement sleeve 2009, the limiting plate 3007 clamps the side, and the operator completes the stirrup binding or welding work, the finished reinforcement cage needs to be moved out of the work area. At this time, the control system commands the lifting components arranged side by side on the upper end of the base platform 13 to move. Each lifting component contains two symmetrically distributed servo hydraulic cylinders 15. The lower end of the servo hydraulic cylinder 15 is fixed to the surface of the base platform 13, and the piston rod inside it extends synchronously under control. The lifting plate 16 fixedly installed at the end of the piston rod moves upward. The surface of the lifting plate 16 slides through the built-in hole 14 opened on the surface of the platform 10. The upper end of the lifting plate 16 is equipped with... The roller frame 17 drives the conveyor roller 18 to pass through the built-in hole 14 and lift it upward, so that the top surface of the conveyor roller 18 is higher than the working plane of the platform 10 and contacts the bottom of the steel reinforcement skeleton. Since the threaded sleeve 2004 in the erection mechanism 2 bears the downward force of the skeleton, and with the support of the conveyor roller 18, the impact during the lifting process is avoided. The conveyor roller 18 is rotatably connected to the roller frame 17 through the roller shaft. After the skeleton is smoothly lifted off the platform 10, the operator can easily push the skeleton along the length of the platform 10. The rolling characteristics of the conveyor roller 18 are used to move the heavy concrete component steel reinforcement skeleton out of the working area, completing the unloading process of the prefabrication operation.
