Description

Technical Field

[0001] This application relates to the field of material storage and formwork, and in particular to an automatic storage and formwork system for shield tunnel segment reinforcement cages. Background Technology

[0002] In the construction industry, rebar cages, as a crucial component of building structures, have a vital impact on the quality and progress of construction projects due to the efficiency and accuracy of their storage and placement. With the continuous development of the construction industry, the requirements for the production, storage, and use of rebar cages are also increasing. An efficient rebar cage storage and placement system can improve the automation level of construction, reduce the workload and errors of manual operations, thereby improving the overall efficiency and quality of construction.

[0003] For the storage of rebar cages, hoisting equipment is usually used to move the rebar cages to the designated location. During the conveying process of the rebar cages, the mechanical equipment is usually manually operated to move the rebar cages from one location to another. For the grabbing and placement of the rebar cages into the mold, grabbers are generally used, and multiple adjustments and calibrations are required by manpower before the rebar cages can be placed into the mold cavity.

[0004] This method relies heavily on manpower, resulting in low handling efficiency and a cumbersome process that can easily lead to inaccurate mold positioning. Therefore, it needs to be improved. Summary of the Invention

[0005] To address the issues of low handling efficiency and inaccurate positioning of steel cages after placement in the formwork during the steel cage placement process, this application provides an automatic storage and placement system for shield tunnel segment steel cages.

[0006] The automatic storage and formwork insertion system for shield tunnel segment reinforcement cages provided in this application adopts the following technical solution: An automatic storage and placement system for steel cages in tunnel lining segments includes a steel cage conveyor, multiple placement frames arranged on a conveying path, a positioning mechanism, and a steel cage placement machine. The steel cage conveyor includes a translation component and a support component. The positioning mechanism is located on one of the placement frames and includes a drive component and a positioning component. Both the drive component and the positioning component are located on the placement frame. The drive component is connected to the positioning component and is used to drive the positioning component to abut against the steel cage, thereby centering the steel cage on the placement frame.

[0007] By adopting the above technical solution, the rebar cage is placed on the placement rack furthest from the rebar cage placement machine. Then, the rebar cage conveyor is started, lifting the rebar cage from the placement rack and moving it towards the rebar cage placement machine, thereby sequentially transporting the rebar cage to the previous placement rack, achieving automatic movement of the rebar cage. When the rebar cage is placed on the placement rack closest to the rebar cage placement machine, the positioning mechanism is activated to center the rebar cage on the placement rack, ensuring that the position of the rebar cage is consistent with the center position of the rebar cage placement machine. This allows the rebar cage placement machine to stably grasp the rebar cage and place it into the mold cavity, achieving the effects of improving the efficiency and positioning accuracy of rebar cage storage and placement, reducing manual operation errors, and improving the production quality of tunnel segments.

[0008] Optionally, the translation assembly includes a translation plate and a plurality of rollers. The translation plate can be inserted into the placement frame, the rollers are rotatably connected to the bottom of the translation plate, and the plurality of rollers are distributed around the perimeter of the translation plate. The supporting assembly includes a supporting cylinder and a supporting rod. The supporting cylinder is disposed on the translation plate, and the output end of the supporting cylinder is connected to the supporting rod. The supporting rod is horizontally arranged, and the supporting cylinder is used to drive the supporting rod to move upward and abut against the reinforcing cage.

[0009] By adopting the above technical solution, the rollers enable the translation plate to move below the placement frame, allowing the support rod to move back and forth between multiple placement frames. When the support cylinder works, its output end extends, driving the support rod to move upward and abut against the rebar cage, thereby lifting the rebar cage and separating it from the placement frame. At this time, the rollers drive the translation plate to move, causing the support rod to move the rebar cage above the placement frame until the rebar cage reaches directly above the previous placement frame. Then, the support cylinder drives the support rod to move downward, making the height of the support rod lower than the placement frame, thereby placing the rebar cage on the placement frame and realizing the sequential transfer of the rebar cage towards the rebar cage placement machine.

[0010] Optionally, the positioning component includes two positioning plates, which are arranged along the length of the placement frame and are symmetrical about the central axis of the placement frame. The side of the positioning plate away from the central axis of the placement frame is rotatably connected to the placement frame via a rotating shaft. The driving component is connected to one end of the rotating shaft to drive the positioning plate to rotate.

[0011] By adopting the above technical solution, the rebar cage conveyor can move between two positioning plates and place the rebar cage on the placement frame. At this time, both ends of the rebar cage are placed on the two positioning plates respectively. Then, the drive assembly is started to drive the rotating shaft to rotate, thereby causing the positioning plates to flip downward around the rotating shaft, so that the positioning plates are tilted downward. That is, the rebar cage overlaps on the tilted plate, thereby restricting the rebar cage in the groove formed by the two positioning plates. This restricts the two ends of the rebar cage, preventing it from moving along the width direction of the placement frame, thus quickly positioning the rebar cage on the central axis of the placement frame.

[0012] Optionally, the drive assembly includes two rotating gears and two rotating racks. The two rotating gears correspond one-to-one with the rotating shafts. The rotating gears are coaxially sleeved on the corresponding rotating shafts and fixed to the rotating shafts. The two rotating gears are located between the two rotating racks. The rotating racks are vertically arranged. The two rotating racks correspond one-to-one with the rotating gears and mesh with the corresponding rotating gears. The two rotating racks are connected by a connecting rod. The placement frame is placed on a worktable. A push cylinder is provided on the worktable. The output end of the push cylinder is connected to the connecting rod and is used to drive the connecting rod to move up and down.

[0013] By adopting the above technical solution, when the jacking cylinder is working, it pushes the connecting rod to move up and down. The connecting rod drives the rotating rack to move, and the rotating rack meshes with the rotating gear, thereby causing the rotating gear to rotate. This, in turn, drives the rotating shaft and the positioning plate to rotate. The connecting rod causes the two rotating racks to move synchronously, thereby causing the two rotating gears to rotate simultaneously. This causes the two positioning plates to flip at the same angle simultaneously, ensuring that the final tilt angle of the two positioning plates is consistent, making the limit of the steel cage symmetrical and improving the positioning accuracy.

[0014] Optionally, the positioning plate is provided with a limiting block, which is arranged along the length direction of the positioning plate.

[0015] By adopting the above technical solution, after the two ends of the rebar cage overlap the positioning plate, the two limiting blocks are located between the two ends of the rebar cage. When the positioning plate tilts downward, the limiting blocks play a restrictive role, preventing the ends of the rebar cage from moving along the width direction of the positioning plate. This avoids the rebar cage from tipping over in the groove formed by the two positioning plates. During this process, the tilted positioning plate and the limiting blocks work together to restrict the translation of the rebar cage while preventing the rebar cage from rotating and tipping over, ensuring that the rebar cage always maintains a positive orientation and improving the stability of the rebar cage positioning.

[0016] Optionally, the positioning plate is provided with an adjustment assembly, which includes an adjustment rod, an adjustment gear, and an adjustment rack. The adjustment rod is disposed in the positioning plate and is arranged along the width direction of the positioning plate. The end of the adjustment rod is rotatably connected to the positioning plate. The adjustment block is slidably connected to the positioning plate. The limiting block is sleeved on the adjustment rod and threadedly connected to the adjustment rod. The adjustment rod rotates to drive the adjustment block to move along the width direction of the positioning plate. The adjustment gear is coaxially sleeved on the adjustment rod and fixed to the adjustment rod. The adjustment rack is slidably connected to the positioning plate and is arranged along the length direction of the positioning plate. The adjustment rack meshes with the adjustment gear.

[0017] By adopting the above technical solution, the adjusting rack is driven to move on the positioning plate, causing the adjusting gear to rotate, which in turn drives the adjusting rod to rotate. When the adjusting rod rotates, the limiting block will move along the width direction of the positioning plate because it is threadedly connected to the adjusting rod. This allows for adjustment of the position of the limiting block, which is located between the two ends of steel cages of different sizes, thus enabling the limiting of steel cages of different sizes and improving applicability.

[0018] Optionally, the two adjusting racks are connected by a linkage plate, one end of the adjusting rack extends out of the positioning plate and is slidably connected to the linkage plate, and a moving cylinder is provided on the worktable. The output end of the moving cylinder is fixed to the linkage plate and is used to drive the linkage plate to move along the length direction of the positioning plate.

[0019] By adopting the above technical solution, when the moving cylinder works, it drives the linkage plate to move along the length of the positioning plate. The linkage plate drives the two adjusting racks to move simultaneously. The adjusting racks mesh with the adjusting gear, thereby causing the adjusting rod to rotate. This causes the two limiting blocks to move the same distance simultaneously, ensuring that the two limiting blocks are symmetrical about the central axis of the placement frame. This achieves symmetrical positioning of the two limiting blocks on the rebar cage, thereby improving the accuracy of positioning.

[0020] Optionally, the positioning assembly further includes a rotating assembly and two arc plates. The rotating assembly is rotatably connected to the worktable, and the two arc plates are arranged symmetrically about the center of the placement frame. The rotating assembly is connected to the arc plates, and the rotating assembly is used to drive the two arc plates to make circular motion about the center of the placement frame. The side of the arc plate closest to the center of the placement frame can abut against the reinforcing cage.

[0021] By adopting the above technical solution, in the initial state, the two arc plates are located on both sides of the placement frame. When the positioning plate tilts and positions the rebar cage on the central axis of the placement frame, the rotating component is activated, driving the two arc plates to make circular motion around the center of the placement frame. This causes the two arc plates to move simultaneously to the area above the placement frame, so that the two arc plates gradually abut against the two opposite corners of the rebar cage. At this time, the two ends and the two opposite corners of the rebar cage are restricted, thereby positioning the rebar cage in the center of the rebar cage. The restriction around the rebar cage prevents the rebar cage from moving, thus achieving the stability of the positioning.

[0022] Optionally, the rotating assembly includes a worm gear, a worm, a transmission gear, and a transmission rack. The worm gear is rotatably connected to the worktable and coaxial with the placement frame. The arc plate is fixed to the worm gear. The end of the worm is rotatably connected to the worktable and meshes with the worm gear. The transmission gear is coaxially sleeved on the worm and fixed to the worm. The transmission rack is vertically arranged, and one end of the transmission rack is fixed to one of the rotating racks. The transmission sleeve meshes with the transmission gear.

[0023] By adopting the above technical solution, when the rotating rack moves, it drives the transmission rack to move. The transmission rack meshes with the transmission gear, causing the transmission gear to rotate. The transmission gear drives the worm to rotate, and the worm meshes with the worm wheel, causing the worm wheel to rotate. This, in turn, drives the arc plate to make a circular motion, so that the rotation of the positioning plate and the movement of the arc plate are synchronized. That is, the two ends of the steel cage are limited at the same time as the two opposite corners of the steel cage, and the four sides of the steel cage are limited at the same time, so as to realize the rapid center positioning of the steel cage on the placement frame.

[0024] Optionally, the rebar cage placement machine includes a truss, a moving assembly, a lifting assembly, and a gripping assembly. The truss is arranged along the direction of the conveying path. The moving assembly is mounted on the truss and connected to the lifting assembly. The moving assembly is used to drive the lifting assembly to move along the length of the truss. The lifting assembly includes a rotating motor, a lifting wheel, a chain, and a lifting rod. The rotating motor and the lifting wheel are both mounted on the moving assembly. The output shaft of the rotating motor is connected to the lifting wheel via a conveyor belt to drive the lifting wheel to rotate. The lifting rod is vertically arranged. The chain is fixed to the lifting rod and arranged along the length of the lifting rod. The lifting wheel meshes with the chain. The rotation of the lifting wheel drives the chain to move up and down. The gripping assembly is located at the bottom end of the lifting rod and is used to grip the rebar cage.

[0025] By adopting the above technical solution, after the steel cage is centered on the placement frame, the moving component is activated, driving the lifting component to move on the truss towards the placement frame. When the grabbing component reaches directly above the steel cage, the rotating motor is activated, driving the lifting wheel to rotate via the conveyor belt. The lifting wheel engages with the chain, causing the chain to move up and down, thereby driving the lifting rod to move downward, driving the grabbing component to reach the steel cage. The grabbing component then hooks up the steel cage, separating it from the placement frame and moving it into the mold cavity.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. The rebar cage conveyor can move between two positioning plates and place the rebar cage on the placement frame. At this time, the two ends of the rebar cage are respectively placed on the two positioning plates. Then, the drive assembly is started to drive the rotating shaft to rotate, thereby causing the positioning plates to flip downward around the rotating shaft, so that the positioning plates are tilted downward. That is, the rebar cage overlaps on the inclined plate, thereby restricting the rebar cage in the groove formed by the two positioning plates, so that the two ends of the rebar cage are restricted and cannot move along the width direction of the placement frame, thereby quickly positioning the rebar cage on the central axis of the placement frame. 2. In the initial state, the two arc plates are located on both sides of the placement frame. When the positioning plate is tilted and the rebar cage is positioned on the central axis of the placement frame, the rotating component is activated to drive the two arc plates to make circular motion around the center of the placement frame. This causes the two arc plates to move simultaneously to the area above the placement frame, so that the two arc plates gradually abut against the two opposite corners of the rebar cage. At this time, the two ends and the two opposite corners of the rebar cage are restricted, thereby positioning the rebar cage in the center of the rebar cage. The restriction around the rebar cage prevents the rebar cage from moving, thus achieving the stability of the positioning. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses an automatic storage and formwork system for the reinforcing cage of tunnel lining segments. (Refer to...) Figure 1 and Figure 2 The automatic storage and placement system for shield tunnel segment reinforcement cages includes a reinforcement cage conveyor 80, multiple placement racks 20 set on the conveying path, a positioning mechanism 30, and a reinforcement cage placement machine 90. The placement racks 20 are mounted on a workbench 10, and the reinforcement cage conveyor 80 moves on the workbench 10 to sequentially transport the reinforcement cages between the multiple placement racks 20. During operation, a reinforcement cage forklift is used to move one reinforcement cage from the reinforcement cage storage to the placement rack 20 at the beginning of the conveying path, and then the reinforcement cage conveyor 80 is activated.

[0031] Reference Figure 1 and Figure 2 The positioning mechanism 30 is installed on the placement frame 20 at the end of the conveying path. The positioning mechanism 30 is used to center the rebar cage on the placement frame 20. The rebar cage placement machine 90 is used to grab the positioned rebar cage and place it into the mold cavity. This improves the efficiency and positioning accuracy of rebar cage storage and placement, reduces human error, and enhances the production quality of tunnel segments. The entire process, through automated equipment and mechanisms, reduces manual intervention, improves operational accuracy and efficiency, and thus enhances overall production quality.

[0032] Reference Figure 1 and Figure 2Specifically, the translation component 81 of the steel cage conveyor 80 includes a translation plate 811 and several rollers 812. The translation plate 811 is typically made of high-strength metal and is a rectangular flat plate that can be inserted into the placement rack 20. The rollers 812 are rotatably connected to the bottom of the translation plate 811, and several rollers 812 are distributed around the perimeter of the translation plate 811. The translation plate 811 and the rollers 812 are connected by bearings, allowing the rollers 812 to rotate flexibly, driving the translation plate 811 to move, thus enabling the support component 82 to move back and forth between the multiple placement racks 20.

[0033] Reference Figure 1 and Figure 2 The support assembly 82 includes a support cylinder 821 and a support rod 822. The support cylinder 821 is mounted on the translation plate 811, and its output end is connected to the support rod 822, which is horizontally positioned. The support cylinder 821 is generally a double-acting cylinder capable of telescopic movement. The support rod 822 is typically made of solid metal with a smooth surface to reduce friction with the reinforcing cage. When the supporting cylinder 821 is working, its output end extends, driving the supporting rod 822 to move upward and abut against the reinforcing cage, thereby lifting the reinforcing cage and separating it from the placement frame 20. At this time, the roller 812 drives the translation plate 811 to move, causing the supporting rod 822 to move the reinforcing cage above the placement frame 20 until the reinforcing cage reaches directly above the previous placement frame 20. At this time, the supporting cylinder 821 drives the supporting rod 822 to move downward, so that the height of the supporting rod 822 is lower than the placement frame 20, thereby placing the reinforcing cage on the placement frame 20, realizing the sequential transfer of the reinforcing cage towards the direction of the reinforcing cage feeding machine 90.

[0034] Reference Figure 3 and Figure 4 The positioning component 32 of the positioning mechanism 30 includes two positioning plates 321. The positioning plates 321 are arranged along the length of the placement frame 20 and are symmetrical about the central axis of the placement frame 20. The side of the positioning plate 321 away from the central axis of the placement frame 20 is rotatably connected to the placement frame 20 via a rotating shaft 3211. The drive component 31 is connected to one end of the rotating shaft 3211 and is used to drive the positioning plates 321 to rotate.

[0035] After the rebar cage conveyor 80 places the rebar cage on the placement frame 20, the two ends of the rebar cage are respectively placed on the two positioning plates 321. Then, the drive assembly 31 is started, which drives the rotating shaft 3211 to rotate, thereby causing the positioning plates 321 to flip downward around the rotating shaft 3211. This causes the positioning plates 321 to be laid out at a downward tilt, that is, the rebar cage overlaps on the tilted plate, thereby restricting the rebar cage in the groove formed by the two positioning plates 321. This restricts the two ends of the rebar cage, preventing it from moving along the width direction of the placement frame 20, thereby quickly positioning the rebar cage on the central axis of the placement frame 20.

[0036] Reference Figure 3 and Figure 4 The drive assembly 31 includes two rotating gears 311 and two rotating racks 312. The rotating gears 311 and racks 312 are typically made of alloy steel, possessing high strength and wear resistance. Each rotating gear 311 corresponds to a rotating shaft 3211, and the gears 311 are coaxially mounted on and fixed to the corresponding shafts 3211. The two rotating gears 311 are located between the two rotating racks 312, which are vertically arranged. Each rack 312 corresponds to a rotating gear 311, and the racks 312 mesh with their corresponding gears 311. The two racks 312 are connected by a connecting rod 40. The placement frame 20 is placed on the worktable 10, on which a push cylinder 41 is mounted. The output end of the push cylinder 41 is connected to the connecting rod 40. When the jacking cylinder 41 is working, it pushes the connecting rod 40 to move up and down. The connecting rod 40 drives the rotating rack 312 to move. The rotating rack 312 meshes with the rotating gear 311, thereby causing the rotating gear 311 to rotate. This, in turn, drives the rotating shaft 3211 and the positioning plate 321 to rotate. The connecting rod 40 causes the two rotating racks 312 to move synchronously, thereby causing the two rotating gears 311 to rotate simultaneously. This causes the two positioning plates 321 to rotate simultaneously by the same angle, ensuring that the final tilt angle of the two positioning plates 321 is consistent, making the limiting of the steel cage symmetrical and improving the positioning accuracy.

[0037] Reference Figure 3 and Figure 4 The positioning plate 321 is provided with limiting blocks 50, which are arranged along the length of the positioning plate 321. When the two ends of the reinforcing cage overlap the positioning plate 321, the two limiting blocks 50 are located between the two ends of the reinforcing cage. When the positioning plate 321 tilts downward, the limiting blocks 50 play a restrictive role, preventing the ends of the reinforcing cage from moving along the width of the positioning plate 321, thereby preventing the reinforcing cage from tipping over in the groove formed by the two positioning plates 321. During this process, the tilted positioning plate 321 and the limiting blocks 50 cooperate to restrict the translation of the reinforcing cage while preventing the reinforcing cage from rotating and tipping over, ensuring that the reinforcing cage always maintains a positive orientation and improving the stability of the positioning of the reinforcing cage.

[0038] Reference Figure 3 and Figure 4The positioning plate 321 is equipped with an adjustment assembly 60, which includes an adjustment rod 61, an adjustment gear 62, and an adjustment rack 63. The adjustment rod 61 is arranged along the width direction of the positioning plate 321, and its end is rotatably connected to the positioning plate 321. An adjustment block is slidably connected to the positioning plate 321, and a limiting block 50 is sleeved on the adjustment rod 61 and threadedly connected to the adjustment rod 61. The adjustment gear 62 is coaxially sleeved on the adjustment rod 61 and fixed to the adjustment rod 61. The adjustment rack 63 is slidably connected to the positioning plate 321 and is arranged along the length direction of the positioning plate 321. The adjustment rack 63 meshes with the adjustment gear 62. Here, the adjustment rod 61 can be a lead screw, which has the characteristics of high precision.

[0039] When the adjusting rack 63 is driven to move on the positioning plate 321, the adjusting gear 62 rotates, thereby driving the adjusting rod 61 to rotate. When the adjusting rod 61 rotates, the limiting block 50 moves along the width direction of the positioning plate 321 because it is threadedly connected to the adjusting rod 61. This allows for adjustment of the position of the limiting block 50, which is positioned between the two ends of different sized steel cages, thus limiting the steel cages of different sizes and improving applicability.

[0040] Reference Figure 3 and Figure 4 Two adjusting racks 63 are connected by a linkage plate 70. One end of the adjusting rack 63 extends out of the positioning plate 321 and is slidably connected to the linkage plate 70. A moving cylinder 71 is provided on the worktable 10. The moving cylinder 71 is generally a double-acting cylinder, and its output end is fixed to the linkage plate 70. When the moving cylinder 71 works, it drives the linkage plate 70 to move along the length of the positioning plate 321. The linkage plate 70 drives the two adjusting racks 63 to move simultaneously. The adjusting racks 63 mesh with the adjusting gear 62, thereby causing the adjusting rod 61 to rotate. This causes the two limiting blocks 50 to move the same distance simultaneously, ensuring that the two limiting blocks 50 are symmetrical about the central axis of the placement frame 20. This achieves symmetrical limiting of the two limiting blocks 50 on the rebar cage, thereby improving the positioning accuracy.

[0041] Reference Figure 3 and Figure 4The positioning component 32 also includes a rotating component 33 and two arc plates 34. The arc plates 34 are generally made of bent steel plates and are arranged symmetrically around the center of the placement frame 20. The rotating component 33 is rotatably connected to the worktable 10 and connected to the arc plates 34, used to drive the two arc plates 34 to perform circular motion around the center of the placement frame 20. Initially, the two arc plates 34 are located on both sides of the placement frame 20. After the positioning plate 321 tilts and positions the rebar cage on the central axis of the placement frame 20, the rotating component 33 is activated, driving the two arc plates 34 to perform circular motion around the center of the placement frame 20. This causes the two arc plates 34 to move simultaneously to the area above the placement frame 20, gradually bringing them into contact with the opposite corners of the rebar cage. At this point, the two ends and opposite corners of the rebar cage are restricted, thus positioning the rebar cage at its center. The restriction around the rebar cage prevents it from moving, achieving stable positioning.

[0042] Reference Figure 3 and Figure 4 The rotating assembly 33 includes a worm gear 331, a worm 332, a transmission gear 333, and a transmission rack 334. The worm gear 331 and worm 332 are typically made of bronze, which has good wear resistance and transmission efficiency. The worm gear 331 is rotatably connected to the worktable 10 and coaxial with the placement frame 20. The arc plate 34 is fixed to the worm gear 331 by a connecting rod.

[0043] Reference Figure 3 and Figure 4 The end of the worm 332 is rotatably connected to the worktable 10 and meshes with the worm wheel 331. The transmission gear 333 is coaxially sleeved on the worm 332 and fixed to it. The transmission rack 334 is vertically arranged and one end is fixed to one of the rotating racks 312. The transmission rack sleeve meshes with the transmission gear 333. When the rotating rack 312 moves, it drives the transmission rack 334 to move. The transmission rack 334 meshes with the transmission gear 333, causing the transmission gear 333 to rotate. The transmission gear 333 drives the worm 332 to rotate. The worm 332 meshes with the worm wheel 331, causing the worm wheel 331 to rotate. This, in turn, drives the arc plate 34 to perform a circular motion. This allows the rotation of the positioning plate 321 and the movement of the arc plate 34 to be synchronized. That is, the two ends of the rebar cage are limited at the same time as the two opposite corners of the rebar cage, and the four sides of the rebar cage are limited at the same time, realizing the rapid center positioning of the rebar cage on the placement frame 20.

[0044] Reference Figure 1 and Figure 5The rebar cage placement machine 90 includes a truss 91, a moving assembly 92, a lifting assembly 93, and a gripping assembly 94. The truss 91 is typically welded from steel beams and is arranged along the direction of the conveying path. The moving assembly 92 is generally an electric slider, mounted on the truss 91 and connected to the lifting assembly 93, used to drive the lifting assembly 93 to move along the length of the truss 91.

[0045] Reference Figure 1 and Figure 5 The lifting assembly 93 includes a rotary motor 931, a lifting wheel 932, a chain 933, and a lifting rod 934. The rotary motor 931 is generally a servo motor, possessing high-precision control performance. Both the rotary motor 931 and the lifting wheel 932 are mounted on the slider of the moving assembly 92. The output shaft of the rotary motor 931 is connected to the lifting wheel 932 via a conveyor belt, driving the lifting wheel 932 to rotate. The lifting rod 934 is vertically positioned, and the chain 933 is fixed to the lifting rod 934 and arranged along the length of the lifting rod 934. The lifting wheel 932 meshes with the chain 933; the rotation of the lifting wheel 932 drives the chain 933 to move up and down. The gripping component 94 is located at the bottom of the lifting rod 934. The gripping component 94 is equipped with a cylinder, which is connected to a gripping hook. When the gripping component 94 is inserted into the rebar cage, the cylinder retracts and the gripping hook catches and holds the rebar cage hoop. This process does not clamp the rebar cage. This method is less likely to cause the rebar cage to shift or the hoop to deform. At the same time, the position of the gripping hook can be adjusted according to different specifications of rebar cages.

[0046] Once the rebar cage is centered on the placement frame 20, the moving component 92 is activated, driving the lifting component 93 to move along the truss 91 toward the placement frame 20. When the grabbing component 94 reaches directly above the rebar cage, the rotating motor 931 is activated, driving the lifting wheel 932 to rotate via the conveyor belt. The lifting wheel 932 engages with the chain 933, causing the chain 933 to move up and down, thereby driving the lifting rod 934 to move downward, driving the grabbing component 94 to reach the rebar cage. The grabbing component 94 then hooks the rebar cage, separating it from the placement frame 20 and moving it into the mold cavity.

[0047] The implementation principle of the automatic storage and placement system for shield tunnel segment reinforcement cages in this embodiment is as follows: Through the coordinated operation of the reinforcement cage conveyor 80, the positioning mechanism 30, and the reinforcement cage placement machine 90, automatic conveying, positioning, and placement of the reinforcement cages into the mold are achieved. The translation component 81 and the support component 82 of the reinforcement cage conveyor 80 can efficiently transport the reinforcement cages sequentially between multiple placement frames 20. The positioning component 32 and the drive component 31 of the positioning mechanism 30 can accurately center the reinforcement cages on the placement frames 20, enabling the reinforcement cage placement machine 90 to align with the reinforcement cages and grasp and move them into the mold cavity. The entire system reduces manual operation, improves the efficiency and positioning accuracy of reinforcement cage storage and placement, reduces human error, and enhances the production quality of shield tunnel segments.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
