Description

Technical Field

[0001] This utility model relates to the field of segment manufacturing technology, and in particular to an arc-shaped main rib storage mechanism and trolley. Background Technology

[0002] With the rapid development of urban underground space development and tunnel engineering construction, shield tunneling technology has become an important means of modern urban infrastructure construction. As the main structural component of shield tunnels, the quality of the tunnel segments directly affects the safety and durability of the tunnel. The segment reinforcement cage is the core load-bearing structure of the segment, and the curved main reinforcement bars, as the main load-bearing components of the reinforcement cage, have undergone a development process in manufacturing and storage technology, evolving from manual production to semi-automation and then to intelligent manufacturing. Early manufacturing of curved main reinforcement bars relied mainly on manual bending and storage. With the expansion of project scale and the increase in quality requirements, mechanized bending and forming and standardized storage management technologies have gradually developed.

[0003] Currently, the manufacturing and storage technology for curved main reinforcement bars used in tunnel segment rebar cages mainly employs specialized bending equipment for mass production, and manages them through classification, labeling, and zoned storage. Existing storage systems typically include fixed storage racks, manual handling equipment, and simple sorting devices, which can meet the basic storage needs of curved main reinforcement bars to a certain extent. Some advanced production lines are also equipped with semi-automated feeding and transfer equipment, improving production efficiency and storage standardization.

[0004] However, in the manufacturing of steel cages for tunnel segments, the existing technology relies mainly on manual operation for storage and transfer, resulting in high labor intensity, low efficiency, and easy damage or deformation of the arc-shaped main reinforcement due to human factors. At the same time, the lack of effective automated control in the feeding and transfer process makes it impossible to achieve precise positioning and smooth transfer, which affects the automation level and production efficiency of the overall production line. Utility Model Content

[0005] The main purpose of this utility model is to propose an arc-shaped main reinforcement storage mechanism and trolley, which aims to solve the technical problems in the existing technology of manufacturing steel reinforcement cages for tunnel segments. Because the storage and transfer process mainly relies on manual operation, the labor intensity is high, the efficiency is low, and the arc-shaped main reinforcement is easily damaged or deformed due to human factors. At the same time, the feeding and transfer process lacks effective automated control, making it impossible to achieve precise positioning and smooth transfer, which affects the automation level and production efficiency of the overall production line.

[0006] To achieve the above objectives, in a first aspect, the present invention provides an arc-shaped main rib storage mechanism, comprising:

[0007] The base has a placement groove on its top that can fit the outer arc surface of the arc-shaped main rib. The two sides of the base are a feeding side and an installation side, respectively.

The sliding component can drive the clamping seat to move between the external loading station and the placement groove through the lifting motion component, so that the clamping seat can clamp and transfer the arc-shaped main rib into the placement groove.

[0018] In one embodiment, a first diagonal brace is also installed between the connecting beam and the support frame.

[0023] In one embodiment, the main reinforcement clamping mechanism further includes a support column, which is disposed opposite to the base on both sides of the external loading station. The connecting beam passes through the top of the external loading station and is rotatably connected to the top of the support column. The support column can drive the connecting beam to rotate relative to the support column and transfer the arc-shaped main reinforcement to the next external station.

[0024] In one embodiment, a rotating ring is provided on the support column, and a second diagonal brace is provided at one end of the connecting beam near the support column.

[0037] The applicant's research found that, in existing technologies, the storage and transfer of curved main reinforcement bars for segment steel cages mainly relies on manual operation, which results in high labor intensity and low efficiency. During manual handling, improper operation can easily cause surface damage or structural deformation of the curved main reinforcement bars, affecting product quality. Existing storage systems mostly use fixed storage racks, which cannot be adjusted according to production needs, leading to positioning deviations between the loading station and the storage mechanism, requiring repeated adjustments to complete material transfer.

[0038] To address the aforementioned issues, considering the bending characteristics of the curved main ribs necessitate a support structure with a specific shape, a placement groove adapted to its outer curved surface is designed to prevent stress concentration during storage. To address the low efficiency of manual handling, a movable base combined with a clamping mechanism is employed to automate material transfer. The support frame drives the entire base to move, allowing the storage mechanism to actively approach or move away from the loading station, eliminating the positional limitations of traditional fixed storage racks.

[0039] This utility model proposes an arc-shaped main rib storage mechanism and trolley.

[0040] Please see Figures 1 to 2For ease of understanding, this arc-shaped main rib storage mechanism includes a base 100, a support frame 300, and a main rib clamping mechanism 400. The top of the base 100 has a placement groove 110 that can adapt to the outer arc surface of the arc-shaped main rib. The two sides of the base 100 are a feeding side 120 and an installation side 130, respectively. The feeding side 120 is located close to the external feeding station 200, on which the arc-shaped main rib to be transferred is placed. The support frame 300 is installed on the installation side 130 and extends upward above the base 100. The support frame 300 can drive the base 100 to move so that the feeding side 120 moves closer to or further away from the external feeding station 200. The main rib clamping mechanism 400 is installed on the top of the support frame 300 and can clamp the arc-shaped main rib placed on the external feeding station 200 and transfer it to the placement groove 110.

[0041] In this embodiment, this application proposes a material storage scheme including a base 100, a support frame 300, and a main rib clamping mechanism 400. The top of the base 100 is provided with a placement groove 110 adapted to the outer arc surface of the curved main rib. The two sides of the base 100 are defined as a feeding side 120 near the external feeding station 200 and a mounting side 130 for mounting the support frame 300, respectively. The support frame 300 is mounted on the mounting side 130 of the base 100 and extends upwards above the base 100, enabling the base 100 to move as a whole to adjust the distance between the feeding side 120 and the feeding station. The main rib clamping mechanism 400 is mounted on top of the support frame 300 and performs the action of grabbing the curved main rib from the feeding station and transferring it to the placement groove 110.

[0042] The base 100 refers to the foundation structure that supports the arc-shaped main rib. It can be made of welded steel plates or cast metal parts. The placement groove 110 on its top matches the outer contour of the arc-shaped main rib, providing stable support. The support frame 300 refers to the frame structure that connects to the base 100 and provides motion functionality. Vertical displacement can be achieved using a hydraulic lifting column or an electric push rod, and horizontal displacement can be achieved through the guide rail 420 mechanism. The main rib clamping mechanism 400 refers to the mechanical device that performs gripping and transferring actions. Material gripping can be achieved using a pneumatic clamp or an electromagnetic chuck, and precise displacement control can be achieved through a servo motor drive.

[0043] Specifically, when material needs to be loaded, the support frame 300 drives the base 100 to move closer to the loading station, shortening the distance between them. After the main rib clamping mechanism 400 grabs the curved main rib from the station, the support frame 300 drives the base 100 back to its initial position, and the clamping mechanism simultaneously transfers the material into the placement groove 110. The curved support surface of the placement groove 110 keeps the main rib in a naturally curved state, avoiding plastic deformation during storage. The movable nature of the base 100 allows the storage mechanism to adapt to production lines with different layouts without the need to readjust the equipment position.

[0044] In this embodiment, the present application realizes automated material storage operation for the arc-shaped main ribs, eliminating surface damage caused by manual handling. The movable nature of the base 100 improves the flexibility of equipment layout, enabling the material storage mechanism to adapt to different loading stations. The arc-shaped support surface effectively maintains the geometry of the main ribs, avoiding structural deformation during storage. The coordinated control of the clamping mechanism and the support frame 300 ensures the smoothness and positioning accuracy of the material transfer process, improving overall production efficiency.

[0045] By setting up a base 100, a support frame 300, and a main rib clamping mechanism 400, during use, the support frame 300 is installed on the mounting side 130 of the base 100, and the feeding side 120 of the base 100 is positioned close to the external feeding station 200. The main rib clamping mechanism 400 is installed on the support frame 300. The main rib clamping mechanism 400 clamps and transfers the arc-shaped main ribs placed on the external feeding station 200 into the placement groove 110, thereby realizing the function of transferring and storing the arc-shaped main ribs. This improves the storage and transfer efficiency of the arc-shaped main ribs, eliminates the need for manual operation, and ensures the automation level and production efficiency of the production line.

[0046] In one embodiment, the main reinforcement clamping mechanism 400 includes a connecting beam 410, a guide rail 420, and a clamping assembly 430. The connecting beam 410 is installed on the top of the support frame 300, and one end of the connecting beam 410 extends above the external loading station 200. The guide rail 420 is installed on one side of the connecting beam 410, and the extension direction of the guide rail 420 is consistent with the extension direction of the connecting beam 410. The two ends of the guide rail 420 are respectively aligned with the two ends of the connecting beam 410. The clamping assembly 430 is installed on the guide rail 420, and the clamping assembly 430 can move relative to the connecting beam 410 along the guide rail 420. The clamping assembly 430 can clamp the arc-shaped main reinforcement placed on the external loading station 200 and transfer the arc-shaped main reinforcement into the placement groove 110.

[0047] Specifically, the connecting beam 410 is a transverse support structure used to support the guide rail 420 and the clamping assembly 430. It can be made of welded I-beams or rectangular tubes, and its extension above the external loading station 200 serves to establish a cross-area transfer channel. The guide rail 420 is a linear guide device that provides a directional movement path for the clamping assembly 430. It can be implemented using a ball linear guide 420 or a gear and rack transmission structure. Its characteristic of extending in the same direction as the connecting beam 410 ensures that the movement trajectory of the clamping assembly 430 coincides with the main rib transfer path. The clamping assembly 430 is an execution unit with clamping and transfer functions. It can be implemented using a pneumatic clamp combined with a servo electric cylinder. Its characteristic of moving along the guide rail 420 ensures that the main rib transfer process forms a linear motion trajectory.

[0048] The connecting beam 410 extends to cover the space between the external loading station 200 and the base 100. The guide rail 420 is arranged along the length of the connecting beam 410 to form a standardized movement path. The sliding engagement of the clamping assembly 430 on the guide rail 420 allows it to reciprocate linearly between the external loading station 200 and the placement slot 110. After the lifting motion component 432 drives the clamping seat 433 to complete the main rib gripping action, the clamping assembly 430 moves along the guide rail 420 to directly above the placement slot 110 for precise placement. This structure eliminates the path deviation of traditional manual handling through the linear guidance of the guide rail 420, and ensures the positioning accuracy of the main rib transfer through mechanized linear motion.

[0049] In this embodiment, the combined design of guide rail 420 and clamping component 430 realizes the fully automated operation of main rib gripping, lifting, translation and lowering. Its linear motion mode has higher path controllability compared with the swing transfer of traditional hoisting equipment. At the same time, the extension structure of connecting beam 410 enables the equipment to adapt to production lines with different layouts.

[0050] In one embodiment, the clamping assembly 430 includes a slider 431, a lifting motion component 432, and a clamping seat 433. The slider 431 is slidably engaged with the guide rail 420 and can slide along the guide rail 420. The lifting motion component 432 is installed at the end of the slider 431 away from the slider. The clamping seat 433 is installed at the bottom of the lifting motion component 432. The lifting motion component 432 can drive the clamping seat 433 to descend and clamp the arc-shaped main rib placed on the external loading station 200. The slider 431 can drive the clamping seat 433 to move between the external loading station 200 and the placement groove 110 through the lifting motion component 432, so that the clamping seat 433 can clamp and transfer the arc-shaped main rib into the placement groove 110.

[0051] Specifically, the sliding component 431 refers to the part that forms a sliding engagement with the guide rail 420. It can be implemented using a sliding component with rollers or a linear bearing. The horizontal movement of the sliding component 431 drives the clamping seat 433 to move between workstations. The lifting motion component 432 refers to the device that drives the clamping seat 433 to move vertically. It can be implemented using a cylinder, electric push rod, or lead screw mechanism. The lifting motion realizes the opening and closing of the clamping action. The clamping seat 433 refers to the clamping component that directly contacts the arc-shaped main rib. It can be implemented using pneumatic grippers, electromagnetic chucks, or mechanical chucks. The shape of the clamping surface adapts to the contour of the arc-shaped main rib.

[0052] The working process of the clamping component 430 is divided into three stages: First, the sliding member 431 moves along the guide rail 420 to directly above the external loading station 200. At this time, the lifting motion component 432 drives the clamping seat 433 to descend until it contacts the arc-shaped main rib. Then, the clamping seat 433 performs a clamping action to fix the main rib, and the lifting motion component 432 drives the main rib to rise and leave the station. Finally, the sliding member 431 moves along the guide rail 420 to above the placement groove 110 of the base 100, and the lifting motion component 432 drives the clamping seat 433 to descend into the placement groove 110 to release the main rib. The entire process achieves precise control of the material transfer path through the combined motion trajectory of sliding and lifting.

[0053] In this embodiment, the combination of linear movement and lifting motion guided by the guide rail 420 forms a repeatable standardized transfer path, eliminating the positional deviation of manual operation, thereby realizing the automated clamping and transfer of the arc-shaped main rib during the material storage process, avoiding surface scratches or deformation caused by manual handling, and ensuring the precise alignment of the main rib in the placement slot 110 through mechanical positioning, thus solving the problems of material damage and positional displacement caused by manual operation in the traditional material storage process.

[0054] In one embodiment, a first diagonal brace 434 is also installed between the connecting beam 410 and the support frame 300.

[0055] Specifically, when the clamping assembly 430 moves along the guide rail 420, the connecting beam 410 is prone to bending vibration under lateral load. The first diagonal brace 434 forms a rigid support through its inclined arrangement, transferring the force on the connecting beam 410 to the vertical frame structure of the support frame 300. For example, during the transfer of the arc-shaped main rib by the clamping seat 433, the diagonal brace can effectively suppress the elastic deformation of the connecting beam 410, ensuring the straightness of the moving trajectory of the clamping assembly 430 and preventing the arc-shaped main rib from shifting or slipping during the transfer due to structural deformation. Ultimately, this effectively solves the problem of the connecting beam 410 being prone to deformation during dynamic operation, ensuring the stability of the clamping mechanism's movement process and avoiding positioning deviations of the arc-shaped main rib due to structural deformation. At the same time, the reinforced design of the diagonal brace extends the service life of key connecting components and reduces the frequency of equipment maintenance.

[0056] In one embodiment, the base 100 includes a base body 140 and a plurality of blocking rods 150. A feeding side 120 and a connecting side are respectively formed on both sides of the base body 140. The connecting side is detachably connected to the support frame 300. A downwardly recessed placement groove 110 is formed on the base body 140. The plurality of blocking rods 150 are distributed circumferentially at intervals on the outer periphery of the placement groove 110, and all blocking rods 150 extend vertically upward.

[0057] Specifically, when the support frame 300 moves the base 100 to the external loading station 200, the arc-shaped contour of the placement groove 110 matches the outer arc surface of the main reinforcement bar to be transferred. Multiple vertically arranged blocking rods 150 surround the placement groove 110 to form a fence structure, which restricts the lateral displacement of the main reinforcement bar during the clamping mechanism's placement of it into the groove 110. The base body 140 and the support frame 300 are connected by a detachable structure for quick assembly and disassembly, facilitating the replacement of the appropriate base 100 component according to different specifications of main reinforcement bars.

[0058] In this embodiment, precise positioning is achieved by setting a placement groove 110 that matches the outer arc surface of the main reinforcement, and a double limit is formed by the circumferentially distributed blocking rods 150, which effectively solves the positioning deviation problem caused by manual operation.

[0059] In one embodiment, the base 100 further includes a plurality of casters 160, which are spaced apart and mounted on the bottom of the base body 140.

[0060] Specifically, the casters 160 are configured to allow the base 100 to be adjusted in position on a horizontal plane. When the base 100 needs to be transferred from the storage position to the processing position, the casters 160 can be unlocked and the base 100 can be pushed to achieve smooth movement. When the base 100 reaches the target position, the casters 160 lock to keep the base 100 stable. The spaced installation method ensures that the base 100 is subjected to uniform force during movement, avoiding displacement or tipping of the arc-shaped main rib within the placement groove 110 due to a shift in the center of gravity. In this embodiment, the spaced arrangement of the casters 160 achieves both flexible movement of the base 100 and ensures stability in both moving and stationary states through multi-point support, reducing manual intervention and reliance on equipment.

[0061] In one embodiment, the main reinforcement clamping mechanism 400 further includes a support column 440, which is disposed opposite to the base 100 on both sides of the external loading station 200. The connecting beam 410 passes through the top of the external loading station 200 and is rotatably connected to the top of the support column 440. The support column can drive the connecting beam 410 to rotate relative to the support column 440 and transfer the arc-shaped main reinforcement to the next external station.

[0062] Specifically, after the clamping seat 433 completes the clamping of the arc-shaped main rib at the external loading station 200, the support column drives the connecting beam 410 to rotate around the axis of the support column 440, causing the clamping seat 433 and the clamped main rib to rotate synchronously to the next station. During this process, the rotation trajectory of the connecting beam 410 covers the working area of ​​the adjacent station, and the lifting motion component 432 drives the clamping seat 433 to descend and complete the placement of the main rib. This rotational transfer method replaces the traditional linear reciprocating motion path, enabling multiple stations to form a circular layout and shortening the travel distance of material transfer.

[0063] In this embodiment, multiple workstations are arranged in a circular direction using a rotary transfer path, allowing for workstation switching to be completed with a single rotation, significantly reducing the equipment's idle travel time. Simultaneously, the trajectory accuracy of the rotational motion is controlled by a servo system, avoiding positioning deviations caused by manual handling.

[0064] In one embodiment, a rotating ring 450 is provided on the support column 440, and a second diagonal brace 460 is provided at one end of the connecting beam 410 near the support column 440. The second diagonal brace 460 is connected to the rotating ring 450, and the connecting beam 410 can rotate around the support column 440 through the rotating ring 450.

[0065] Specifically, when the curved main rib needs to be transferred to the next external workstation, the support column 440 drives the connecting beam 410 to rotate via the rotating ring 450. The second diagonal brace 460 converts the rotational motion of the connecting beam 410 into a stable circular motion around the support column 440. During the rotation, the connecting beam 410 drives the clamping assembly 430 to move synchronously via the guide rail 420. The clamping seat 433, driven by the lifting motion component 432, smoothly transfers the curved main rib from the placement slot 110 to the target workstation. The cooperation between the rotating ring 450 and the support column 440 reduces frictional resistance during rotation, while the second diagonal brace 460, through rigid connection, restricts the radial displacement of the connecting beam 410, ensuring the accuracy of the transfer path.

[0066] In this embodiment, the coordinated action of the rotating ring 450 and the second diagonal brace 460 not only enables the flexible rotation of the connecting beam 410, but also suppresses vibration and offset during rotation through the rigid support of the diagonal brace, thus solving the problem of deformation of the arc-shaped main reinforcement caused by instability in the transfer process in the prior art.

[0067] In one embodiment, the connecting beam 410 includes a connecting section 411 and a telescopic section 412. The connecting section 411 and the telescopic section 412 are slidably engaged, and the connecting section 411 can be accommodated within the telescopic section 412. The end of the connecting section 411 away from the telescopic section 412 is connected to the support column 440, and the end of the telescopic section 412 away from the connecting section 411 is connected to the support frame 300. The guide rail 420 is installed on the outer side wall of the telescopic section 412, and the guide rail 420 is arranged along the extension direction of the telescopic section 412.

[0068] Specifically, when the working range of the storage mechanism needs to be adjusted, the telescopic section 412 can extend and retract along the slide groove of the connecting section 411. During the transfer of the arc-shaped main rib, the clamping assembly 430 moves along the guide rail 420 installed on the outside of the telescopic section 412, and cross-station transfer is achieved through the rotational connection between the connecting section 411 and the support column 440. The extension direction of the telescopic section 412 is consistent with the arrangement direction of the guide rail 420, ensuring that the movement trajectory of the clamping assembly 430 is coordinated with the telescopic adjustment direction of the storage mechanism.

[0069] In this embodiment, the retractable connecting beam 410 structure allows for flexible adjustment of the working range according to actual working conditions, solving the problem of poor versatility of existing equipment. Simultaneously, the guide rail 420 is directly installed on the outside of the telescopic section 412, avoiding track misalignment caused by beam expansion and contraction, and ensuring the stability of the clamping assembly 430's movement trajectory.

[0070] Based on the same technical concept, in a second aspect, this utility model also proposes an arc-shaped main rib storage trolley, which applies the arc-shaped main rib storage mechanism of the first aspect.

[0071] Specifically, the storage trolley adapts to the shape of the curved main rib via the placement slot 110 of the base 100, ensuring storage stability. The support frame 300 moves the base 100 closer to or further away from the external loading station 200, cooperating with the main rib clamping mechanism 400 to move along the guide rail 420 and complete the clamping action, realizing the automatic transfer of the curved main rib from the external station to the placement slot 110. The casters 160 at the bottom of the base 100 enable the trolley to move, and the rotating connection structure between the support column 440 and the connecting beam 410 allows the connecting beam 410 to rotate around the support column 440, thereby transferring the curved main rib to the next station. The extension section 412 makes the length of the connecting beam 410 adjustable to adapt to different station spacing requirements.

[0072] In this embodiment, the automated transfer of the arc-shaped main rib is achieved by integrating a mobile trolley with an automated clamping mechanism. In the prior art, manual operation is prone to deformation of the main rib. This solution avoids the risk of collision during manual handling by using mechanical clamping and guide rail 420 for guidance control.
