Description

Technical Field

[0001] The present invention relates to the field of concrete beam construction, and in particular to a high-speed railway beam yard annular production line and a production method. Background Art

[0002] Due to their structural importance, bridge beams are typically produced in a centralized manner to ensure efficiency and product quality. To fully utilize production space and ensure the smooth production of beams, existing beam production lines are typically divided into six areas: the casting area, the steaming and curing area, the diaphragm casting area, and the tensioning, grouting, and end-capping area. In the casting area, the beam pedestal and formwork are used to cast the concrete for the beam body; the steaming and curing area is used to steam-cure the cast beam body; the diaphragm casting area is responsible for casting the diaphragms after the main beam body is cast and cured; and the tensioning, grouting, and end-capping area performs tensioning, grouting, and end-capping on the beam body, thereby creating prestress within the beam. Furthermore, two auxiliary areas are included: the rebar tying area, used for tying and storing the beam rebar cradles, and the beam storage area, used to store the beam body after production. This division, to a certain extent, meets the requirements for centralized and standardized production of bridge beams.

[0003] However, the existing technology still has many shortcomings. In traditional production, beams are usually moved between production areas by gantry cranes, which are slow and other processes cannot be carried out during the movement, resulting in low production efficiency, high labor intensity, and difficulty in ensuring product quality. To improve the above problems, the existing technology has introduced movable pedestals, fixed outer molds with integral hydraulic mold closing and demolding, and fixed steaming areas, which greatly improved production efficiency and the speed of increasing beam strength. However, this method of moving the pedestal on rails is only suitable for the production of lighter beams such as highways and municipal projects. For high-speed railway beams, due to their large size and high weight (for example, the commonly used 32-meter beams weigh thousands of tons), the mobile pedestal is difficult to push and is easily damaged, which not only delays the construction period but also makes it difficult to ensure the quality of the beam. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention proposes a high-speed railway beam yard circular production line and production method, which forms an efficient and automated production process by setting up a fixed pedestal, a hydraulic integral template, a mobile steaming room and a circular track system.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A high-speed railway beam yard circular production line includes a fixed pedestal, a hydraulic integral formwork, a mobile steaming and curing room and a track system. The fixed pedestals include multiple fixed pedestals, and the track system includes a longitudinal track and a transverse track. The longitudinal track is arranged in parallel on both sides of the fixed pedestal, and the transverse track connects the ends of the longitudinal track. The longitudinal track and the transverse track form a circular track; the hydraulic integral formwork is arranged on the circular track and circulates between the fixed pedestals through the track system to complete the casting of the beam body and the opening and closing of the formwork on the fixed pedestals; the mobile steaming and curing room is arranged on the circular track and moves to the fixed pedestal where the casting and demolding of the beam body have been completed through the track system to steam the beam body.

[0007] Preferably, there are four fixed seats.

[0008] Preferably, the outer formwork support frame of the hydraulic integral formwork is provided with rollers, which cooperate with the track system.

[0009] Preferably, the mobile steaming room includes a steaming room structure support assembly, a driving assembly and a steaming assembly. The steaming room structure support assembly includes a supporting frame, front and rear doors and a lower connecting member. The lower connecting member is driven by an electric cylinder to rotate and is used to connect with a fixed base to form a closed space; the driving assembly includes walking wheels and a driving motor arranged at the bottom of the supporting frame. The walking wheels include powered rollers and unpowered rollers. The powered rollers are driven by the driving motor; the steaming assembly includes a steam generator, a steam connecting pipe, a joint, pipes in the steaming room and a nozzle.

[0010] Preferably, the nozzles are evenly arranged inside the steaming room.

[0011] Preferably, the powered roller is located on a side close to the fixed base, and the unpowered roller is located on a side away from the fixed base.

[0012] Preferably, a groove is provided on the ground, and the track system is fixedly arranged in the groove to cooperate with the power roller, and the driving assembly guides the mobile steaming room to move along the production line through the track system.

[0013] Preferably, a steering system is also included, which adopts a pulley steering device, a transverse ferry, a translation crane, a switch switch or a longitudinal and transverse wheel steering device to realize the movement of the hydraulic integral template and the mobile steaming room between the longitudinal track and the transverse track.

[0014] The present invention also discloses a production method based on the above-mentioned high-speed railway beam yard ring production line, comprising the following steps:

[0015] S1: After the hydraulic integral formwork is positioned in the transverse area, it is moved to the first fixed pedestal area. After the formwork is closed, the beam reinforcement is hoisted in as a whole to complete the pouring of the beam concrete.

[0016] S2, after the concrete pouring of the beam body in the first fixed pedestal area is completed, the formwork is removed and the hydraulic integral formwork is moved to the second fixed pedestal area to start the prefabrication of the beam body;

[0017] S3, after the beams in the second fixed pedestal area are completed, the hydraulic integral formwork is moved to the transverse movement area, and then moved to the longitudinal movement tracks of the third and fourth fixed pedestals via the transverse movement tracks;

[0018] S4, moving longitudinally to the third fixed pedestal area in sequence to cast the beam body and open and close the formwork, and then moving to the fourth fixed pedestal area to complete the corresponding process;

[0019] S5, moving the hydraulic integral template from the fourth fixed pedestal area back to the transverse movement area, and moving it to the first fixed pedestal area through the transverse movement track, forming a circulation process of the ring production line.

[0020] Preferably, the method further includes the following steps: after the hydraulic integral formwork moves from the transverse movement area to the first fixed pedestal area, a mobile steaming-curing room is assembled in the transverse movement area; after the hydraulic integral formwork moves from the first fixed pedestal area to the second fixed pedestal area, the mobile steaming-curing room is moved to the first fixed pedestal area to steam-cure the beam body that has just been demolded; the above steps are repeated so that the mobile steaming-curing room steams the beam body that has just been demolded as the hydraulic integral formwork moves.

[0021] The present invention has the following beneficial effects: The fixed pedestal design provides a strong and stable base structure with excellent load-bearing capacity, effectively ensuring the quality of large beam casting. Since both the pedestal and beam remain in a fixed position and do not need to be moved, the risk of collision, tilting, or falling during the production process is reduced, thereby improving production safety and stability. Furthermore, the design of a movable hydraulic integral formwork makes the mold closing and disassembly process more efficient and convenient, conserving formwork. The hydraulic operation not only reduces labor intensity but also avoids the misalignment and joint problems that can occur with traditional assembled formwork, significantly improving the appearance quality and production consistency of the beam concrete. The present invention utilizes a circular track system to streamline the pouring, steaming, and tensioning and grouting processes, seamlessly connecting each step and significantly improving production efficiency. Furthermore, the mobile steaming room design makes the steaming process more convenient and efficient, rapidly improving the strength of the beam concrete and effectively shortening the production cycle. Overall, the present invention's circular production line and production method for high-speed rail beam yards combine high efficiency, high quality, and low labor intensity, providing a highly practical solution for the large-scale production of high-speed rail beams.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the present invention.

[0029] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0030] See also Figure 1-3, this embodiment provides a high-speed railway beam yard circular production line, including a fixed pedestal 1, a hydraulic integral formwork 2, a mobile steaming room 3 and a track system 4. Among them, the fixed pedestal 1 includes multiple ones, which are arranged along the track system 4 and evenly distributed in different areas of the production line. Specifically, there can be four fixed pedestals 1, namely a first fixed pedestal 101, a second fixed pedestal 102, a third fixed pedestal 103 and a fourth fixed pedestal 104. According to the pouring, steaming, tensioning and grouting processes of the concrete of the beam body 5, it is most economical and reasonable to equip a set of hydraulic integral formwork 2 with four fixed pedestals 1, thereby forming a circular beam yard production line. Through such an arrangement, the circulation efficiency of the formwork can be maximized, ensuring a high degree of coordination of each process in time and space, reducing the situation where the formwork is waiting or idle during the production process, and optimizing the overall resource allocation.

[0031] The track system 4 comprises longitudinal tracks 41 and transverse tracks 42. The longitudinal tracks 41 are arranged parallel to the fixed base 1, supporting and guiding the longitudinal movement of the hydraulic integral formwork 2 and the mobile steam-curing chamber 3. The transverse tracks 42 connect the ends of the longitudinal tracks 41, forming a closed-loop track layout. This layout ensures continuity and cyclical operation between production line processes, effectively improving production efficiency.

[0032] The hydraulic integral formwork 2 is set on a circular track and can be circulated between the fixed pedestals 1 through the track system 4, and is used to complete the casting of the beam body 5 and the opening and closing of the formwork on the fixed pedestal 1. The hydraulic integral formwork 2 adopts a hydraulic drive method to perform the mold closing and demolding operations of the formwork, which reduces the complexity of manual operation and significantly reduces labor intensity. At the same time, the integral formwork design effectively avoids the misalignment and joint problems that may occur during the assembly of traditional formwork, ensuring the appearance quality and structural consistency of the beam body 5. In addition, the outer mold support frame of the hydraulic integral formwork 2 is provided with rollers, which cooperate with the track system 4 to achieve smooth movement of the hydraulic integral formwork 2 on the track system 4.

[0033] Mobile steam-curing room 3 is also mounted on a circular track. It can be moved via track system 4 to fixed pedestal 1, where beam 5 has been cast and demolded, to steam-cur the beam 5. The mobile steam-curing room 3 is designed to move freely on track system 4, enabling rapid steam curing of the beam 5. This significantly improves the strength and hardening speed of the concrete, thereby accelerating overall production. This circular production line boasts a rational structure and efficient operation, making it suitable for large-scale production of high-speed rail beams.

[0034] Furthermore, the mobile steaming room 3 includes a steaming room structural support assembly, a drive assembly, and a steaming assembly. The steaming room structural support assembly includes a support frame 6, front and rear doors, and a lower connecting member 7. The support frame 6 provides overall structural support for the steaming room 3, ensuring sufficient stability during movement and use. The front and rear doors are used to enclose the interior space of the steaming room 3 and facilitate the entry and exit of the beam 5. The lower connecting member 7 is driven by an electric cylinder 8 to rotate and is used to connect with the fixed base 1 to form a closed steaming space, thereby achieving a completely sealed curing environment for the beam 5. The closed steaming space of the steaming room 3 is compatible with the structure of the beam. The design of the lower connecting member 7 can ensure a close fit with the fixed base 1, prevent steam leakage, effectively improve steaming efficiency, and save energy. The drive assembly includes running wheels and a drive motor 9 arranged at the bottom of the support frame 6.

[0035] The running wheels include a powered roller 10 and an unpowered roller 11. The powered roller 10 is driven by the drive motor 9 to enable the steaming room 3 to move on the track system 4. The powered roller 10 is located on the side close to the fixed base 1, and the unpowered roller 11 is located on the side away from the fixed base 1. The setting of the powered roller 10 ensures the precise movement of the steaming room 3, while the unpowered roller 11 serves as an auxiliary support to ensure stability during the movement. The powered roller 10 can be connected to the same support frame as the lower connecting member 7. The steaming assembly includes a steam generator 12, a steam connecting pipe 13, a joint 14, a pipe 15 in the steaming room, and a nozzle 16. The steam generator 12 transports steam to the steaming room 3 through the steam connecting pipe 13. The design of the joint 14 ensures the sealing and flexibility of the connection, and adapts to the slight displacement or vibration of the steaming room 3 during movement. The pipe 15 in the steaming room is used to transport steam to the nozzle 16. The nozzle 16 is evenly arranged inside the steaming room 3. Through uniform steam injection, it is ensured that the beam body 5 can obtain a uniform temperature and humidity environment during the steaming process, thereby accelerating the improvement of concrete strength and optimizing the production cycle of the beam body 5.

[0036] The track system 4 is fixedly mounted in a groove 17 on the floor, cooperating with the power roller 10. This groove 17 not only secures and protects the track system 4, but also prevents wear and contamination from exposed tracks, extending the service life of the track system 4. The drive assembly guides the mobile steaming room 3 along the production line via the track system 4, enabling efficient transitions from one fixed pedestal 1 to another, ensuring smooth operation of the assembly line.

[0037] In this embodiment, the high-speed rail beam yard circular production line also includes a steering system. The steering system uses a pulley steering device, a transverse shuttle bus, a translation crane, a switch switch, or a longitudinal and transverse wheel steering device to enable the hydraulic integral formwork 2 and the mobile steam-curing room 3 to move between the longitudinal track 41 and the transverse track 42. The diverse design of the steering system can adapt to different site layouts and production requirements. For example, the pulley steering device is suitable for smaller sites, while the translation crane is suitable for large-span site structures. This flexible steering method ensures that the hydraulic integral formwork 2 and the mobile steam-curing room 3 can quickly and smoothly complete the track change, effectively reducing production time and improving the efficiency of the entire production line.

[0038] Furthermore, the steaming component also includes a temperature and humidity monitor and an external display device for monitoring and controlling the temperature and humidity within the steaming room. The temperature and humidity monitor collects real-time temperature and humidity data from the steaming room, and the external display device intuitively displays this data to the operator, facilitating real-time adjustment of steam volume and other parameters to ensure the steaming environment is always in optimal condition. The mobile steaming room 3 also includes an intelligent system, which includes an obstacle avoidance system, a position limiting system, and a warning system. The obstacle avoidance system detects obstacles and transmits obstacle information back to the control module; the position limiting system ensures that the steaming room stops when it reaches a predetermined area and prevents derailment; and the warning system issues warning signals during the movement and steaming process of the steaming room. The addition of the intelligent system makes the operation of the steaming room more automated and safer. The obstacle avoidance system can monitor obstacles in the moving path in real time and send data to the control module in advance to adjust the moving path and prevent collisions. The position limiting system ensures that the steaming room stops precisely when it moves to a preset position, preventing excessive movement or derailment. The warning system includes sound and light alarm devices, which send warning signals to the surrounding environment during the movement and steaming process in the steaming room to remind staff to pay attention and improve operational safety.

[0039] Another embodiment of the present invention describes a production method based on the above-mentioned high-speed railway beam yard ring production line, comprising the following steps:

[0040] S1: After the hydraulic integral formwork 2 is positioned in the transverse zone, it is moved to the area of ​​the first fixed pedestal 101. After the formwork is closed, the beam reinforcement is hoisted in, completing the concrete pouring of the beam 5. The hydraulic integral formwork 2 smoothly transitions from the transverse track 42 to the longitudinal track 41 via the track system 4 and is accurately positioned above the first fixed pedestal 101. The hydraulic drive system of the hydraulic integral formwork 2 ensures precise closing of the formwork, providing a reliable operating environment for pouring the reinforcement of the beam 5.

[0041] S2: After the concrete pouring of the beam 5 in the area of ​​the first fixed pedestal 101 is completed, the formwork is removed and the hydraulic integral formwork 2 is moved to the area of ​​the second fixed pedestal 102 to begin prefabrication of the beam 5. The formwork removal operation is performed quickly and reliably by the hydraulic system. The hydraulic integral formwork 2 is smoothly moved to the second fixed pedestal 102 via the track system 4, enabling efficient transition to the next production step.

[0042] S3: After the beam 5 in the area of ​​the second fixed pedestal 102 is completed, the hydraulic integral formwork 2 is moved to the transverse movement area and moved via the transverse movement track 42 to the longitudinal movement track 41 of the third fixed pedestal 103 and the fourth fixed pedestal 104. The transverse movement area, through the coordination of the steering system, ensures that the hydraulic integral formwork 2 can smoothly complete track switching, adapting to track movement requirements in different directions, and avoiding time loss caused by poor steering.

[0043] S4: The hydraulic formwork 2 moves longitudinally to the third fixed pedestal 103 to cast the beam 5 and disassemble the formwork, and then moves to the fourth fixed pedestal 104 to complete the corresponding process. During the formwork assembly and disassembly process, the precise coordination of the track system 4 and the rollers ensures that the hydraulic integral formwork 2 maintains stable operation, preventing deviation or tilt from affecting production.

[0044] In step S5, the hydraulic integral formwork 2 is moved from the fourth fixed pedestal 104 area back to the transverse movement area and then, via transverse movement track 42, to the first fixed pedestal 101 area, forming a circular production line. After completing the last process, the hydraulic integral formwork 2 quickly returns to its initial position, preparing for the next production cycle. The closed-loop design of the track system 4 efficiently connects the entire production process, ensuring continuous production of the beam 5 and improving overall production efficiency.

[0045] This embodiment also includes the following steps: After the hydraulic integral formwork 2 moves from the transverse zone to the first fixed pedestal 101, a mobile steaming and curing chamber 3 is assembled in the transverse zone. The mobile steaming and curing chamber 3 is guided by a track system 4. Relying on the precise track design, the mobile steaming and curing chamber 3 allows for rapid assembly and positioning of components in the transverse zone, ensuring stability for subsequent operations. After the hydraulic integral formwork 2 moves from the first fixed pedestal 101 to the second fixed pedestal 102, the mobile steaming and curing chamber 3 is moved to the first fixed pedestal 101 to steam-cure the newly removed beam 5. The steaming and curing system of the mobile steaming and curing chamber 3 sprays steam onto the beam 5 through evenly spaced nozzles 16, creating a constant temperature and humidity environment and rapidly increasing the strength of the concrete. The movement of the steaming and curing chamber 3 is coordinated with the movement of the hydraulic integral formwork 2, ensuring that the steaming and curing process is synchronized with the cyclic movement of the formwork. These steps are repeated, allowing the mobile steaming and curing chamber 3 to steam-cure the newly removed beam 5 as the hydraulic integral formwork 2 moves. During this process, the mobile steaming room 3 can be flexibly moved on the track system 4, eliminating the need for additional manual operation and increasing the degree of automation. This coordinated approach enables efficient, streamlined steaming of the beams 5, significantly improving production efficiency while ensuring consistent quality across each beam and seamless process integration. This dynamic, synchronized steaming mode not only saves production time but also reduces energy consumption, providing a reliable guarantee for the efficient operation of the beam yard.

[0046] In this production method, the rational connection of each step enables streamlined production of the beam 5. The ring track system, combined with the automated operation of the hydraulic integral formwork 2, significantly reduces manual intervention and improves production efficiency, while ensuring the quality of the beam 5 and process stability. This provides an efficient and reliable production solution for modern high-speed rail beam yards.

[0047] See also Figure 4 In order to further expand production capacity and make full use of the site, another production line can be connected to the back of a circular production line. The two production lines share the transverse movement area and transverse movement track 42, thereby saving space for site layout and reducing the infrastructure costs required for the new production line. For example, the second circular production line can be arranged in parallel with the first production line to form a more efficient multi-line production model. Depending on the size of the site, the number of circular production lines can also be extended, and the length of the production line can be flexibly adjusted to meet different production needs by adding fixed bases 1 and track systems 4. Similarly, if site conditions permit, production lines can be added horizontally to further expand the scale of production. This scalable design can not only meet current production needs, but also leave enough room for development for future capacity increases, providing a flexible and reliable solution for the efficient operation of the beam yard.

[0048] See also Figure 5Furthermore, the steam connecting pipe 13 includes a pre-buried steam pipe, which is set underground and guides steam to the other side of the fixed base 1 facing away from the steam generator 12. The steam generator 12 is set outside the production line, for example, a steam generator 12 is set between the production lines. One steam generator 12 can provide steam supply for two or four steam curing rooms at the same time.

[0049] In summary, the present invention proposes a circular production line and production method for a high-speed rail beam yard, comprising a fixed pedestal 1, a hydraulic integral formwork 2, a mobile steaming room 3, and a track system 4. The circular track design enables efficient movement of the beam 5 between various production processes. Combined with the rapid mold closing and unmolding of the hydraulic integral formwork 2 and the flexible steaming operation of the mobile steaming room 3, this forms an efficient and automated production process. To address the problems of low production efficiency, high labor intensity, and difficulty in ensuring product quality in traditional beam yards, the fixed pedestal and circular track layout improves the consistency and safety of the production line. The hydraulic integral formwork significantly reduces the burden of manual operation, and the mobile steaming room accelerates the improvement of beam strength. The present invention optimizes the connection between multiple processes, including beam casting, steaming, and tensioning and grouting, reducing production time and improving production efficiency, while ensuring the quality and appearance consistency of the beam. Furthermore, the present invention has excellent scalability. Production capacity can be expanded by increasing the number of circular production lines or extending their length, or by further increasing production capacity by horizontally stacking production lines, fully adapting to site conditions and production needs. The present invention is suitable for large-scale production in high-speed railway beam yards, and has important application value, especially in scenarios with high production capacity requirements and strict quality standards. It provides a modern beam yard with an efficient, energy-saving and safe production solution, and has broad prospects for promotion and application.
