Description

Technical Field

[0001] This utility model relates to the field of concrete steam curing, and in particular to a mobile steam curing chamber for beams. Background Technology

[0002] After concrete is poured, it needs to be cured to ensure that its final strength meets design requirements. As the direct load-bearing structure, the beam structure in bridge engineering has extremely high requirements for concrete quality, making its curing process particularly important. Currently, common methods for curing bridge beam concrete include water spraying and covering, and steam curing. Water spraying and covering keeps the concrete moist by regularly sprinkling water, and the curing process is relatively simple and easy to operate; while steam curing rapidly increases the strength of the concrete by maintaining a constant temperature and humidity in a fixed, enclosed space. These two curing methods are widely used in bridge engineering and, to a certain extent, meet the requirements for concrete quality.

[0003] However, existing technologies also have significant drawbacks. While watering and covering for curing are simple, they are time-consuming, typically requiring 5-7 days, and necessitate frequent watering, resulting in low efficiency and difficulty in fully guaranteeing concrete quality. In contrast, steam curing can increase concrete strength to over 90% of its design strength within 8-10 hours, offering higher efficiency. However, steam curing requires a fixed, enclosed space, and transporting large beams to this area consumes considerable time and manpower. Furthermore, operation and inspection within a fixed location during steam curing are inconvenient, further impacting construction efficiency and operational flexibility. Utility Model Content

[0004] In view of the above-mentioned defects of the existing technical solutions, the main purpose of this utility model is to develop a mobile steam curing chamber for beams. By introducing a mobile design, the steam curing chamber can be moved along the track to the location of the beam for steam curing, without having to transport the beam to a fixed location.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A movable steam curing chamber for beams, used for steam curing of beams, includes a steam curing chamber structural support system, a drive system, and a steam curing system. The steam curing chamber structural support system includes a support frame, front and rear doors, and a lower connecting component. The lower connecting component is driven by an electric cylinder to rotate and connect with a fixed base to form an enclosed space. The drive system includes wheels and a drive motor located at the bottom of the support frame. The wheels include powered rollers and unpowered rollers, with the powered rollers driven by the drive motor. The steam curing system includes a steam generator, steam connection pipes, joints, pipes inside the steam curing chamber, and nozzles. The nozzles are evenly distributed inside the steam curing chamber.

[0007] Preferably, the steam curing system further includes a temperature and humidity monitor and an external display device for monitoring and controlling the temperature and humidity inside the steam curing room.

[0008] Preferably, the steam connection pipe includes a pre-embedded steam pipe, which is installed underground to guide steam to the side of the fixed platform opposite the steam generator.

[0009] Preferably, the powered roller is located on the side closer to the fixed base, and the unpowered roller is located on the side farther away from the fixed base.

[0010] Preferably, a groove is provided on the ground, and a track is fixedly installed in the groove. The track cooperates with the power roller, and the drive system guides the steam curing chamber to move along the production line through the track.

[0011] Preferably, it also includes a steering system, which employs a pulley steering device, a lateral transfer vehicle, a translation crane, a turnout switch, or a longitudinal and transverse wheel steering device to enable the curing chamber to be smoothly transferred from one longitudinal track to another.

[0012] Preferably, it also includes an intelligent system, which includes an obstacle avoidance system, a limit system, and a warning system. The obstacle avoidance system is used to detect obstacles and transmit obstacle information back to the control module; the limit system is used to ensure that the steam curing chamber stops moving when it reaches the predetermined area and to prevent derailment; the warning system is used to issue warning signals during the movement of the steam curing chamber and during the steam curing process.

[0013] Preferably, the warning system includes an audible and visual alarm device.

[0014] Preferably, the steam connection pipe is connected at the joint via a flexible joint.

[0015] Preferably, the nozzles are evenly arranged in an array at the top of the steam curing chamber.

[0016] The beneficial effects of this utility model are as follows: The steam curing chamber has been improved from a traditional fixed design to a mobile one, greatly enhancing the flexibility and efficiency of the equipment. In practical applications, the steam curing chamber can be moved directly along the track to the beam platform for steam curing, eliminating the need to transport large beams to a fixed steam curing area via hoisting or other complex equipment, thus significantly saving production time and construction costs. The mobile steam curing chamber design greatly improves equipment utilization, allowing for flexible scheduling. The same steam generator can serve multiple production lines, effectively reducing equipment investment and operating costs. Furthermore, the intelligent design simplifies the operation process. For example, the drive and steering systems enable automatic movement and precise positioning, while the temperature and humidity monitoring system ensures the stability of the steam curing environment, further improving the quality of beam steam curing. At the same time, operators do not need to frequently enter the steam curing area for inspection, effectively reducing labor intensity and improving work safety. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model belong to the present utility model.

[0024] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0025] Please see Figure 1-3 This embodiment discloses a movable steam curing chamber for beams, which is used for steam curing of beams, including a steam curing chamber structural support system, a drive system and a steam curing system.

[0026] The structural support system of the steam curing chamber includes a support frame 1, front and rear doors, and a lower connecting component 2. The lower connecting component 2 is driven to rotate by an electric cylinder 3 and is used to connect with the fixed platform 4 to form a closed space. Through precise fitting with the fixed platform 4, a completely sealed steam curing environment is formed to prevent steam leakage, thereby improving steam curing efficiency and saving energy.

[0027] The drive system includes traveling wheels and a drive motor 5 located at the bottom of the support frame 1. The traveling wheels include powered rollers 6 and unpowered rollers 7, with the powered rollers 6 driven by the drive motor 5. The drive system provides rotational power to the powered rollers 6 via the drive motor 5, enabling the curing chamber to move smoothly along the track and quickly and accurately reach the beam platform where curing operations are required. The unpowered rollers 7 provide balance and support, ensuring the curing chamber operates stably and without tilting during movement. The powered rollers 6 are located on the side closer to the fixed platform 4, while the unpowered rollers 7 are located on the side farther from the fixed platform 4. A groove 14 is provided in the ground, and a track 15 is fixedly installed within the groove 14. The track 15 cooperates with the powered rollers 6, and the drive system guides the curing chamber along the production line via the track 15. The combined design of the groove 14 and the track 15 not only ensures the straightness of the curing chamber's operation but also protects the track from external damage, further improving the operating efficiency and durability of the drive system. In addition, the non-powered roller 7 does not require additional tracks and can move directly on the ground. The non-powered roller 7 reduces the installation cost of tracks and further enhances the flexibility and stability of the steam curing chamber during operation, adapting to various working environments.

[0028] The steam curing system includes a steam generator 8, a steam connection pipe 9, a connector 10, pipes 11 inside the steam curing chamber, and nozzles 12. The steam generator 8 supplies steam to the steam curing chamber through the steam connection pipe 9. The connector 10 ensures the sealing and flexibility of the connection of the steam connection pipe 9, facilitating the movement and operation of the steam curing chamber. The steam connection pipe 9 can be connected at the connector 10 using a flexible joint, which can accommodate minor displacements or vibrations that may occur during the movement of the steam curing chamber, preventing loosening or damage at the connection point. The pipes 11 inside the steam curing chamber deliver steam to the nozzles 12, which are evenly distributed throughout the chamber. The nozzles 12 are evenly arranged in an array at the top of the steam curing chamber. This arrangement of the nozzles 12 ensures that the steam is evenly distributed inside the steam curing chamber, creating a constant temperature and humidity environment, effectively improving the steam curing quality of the beam and shortening the steam curing time.

[0029] Furthermore, the steam curing system also includes a temperature and humidity monitor and an external display device for monitoring and controlling the temperature and humidity inside the steam curing chamber. The temperature and humidity monitor collects real-time temperature and humidity data inside the steam curing chamber, and the external display device displays this data intuitively to the operator, facilitating real-time adjustment of steam volume and other parameters to ensure that the steam curing environment is always in optimal condition.

[0030] See Figure 3 Furthermore, the steam connection pipe 9 includes a pre-embedded steam pipe 13, which is installed underground and guides steam to the side of the fixed platform 4 opposite to the steam generator 8. The steam generator 8 is installed outside the production line, for example, between production lines. One steam generator 8 can simultaneously supply steam to two or four curing chambers. The underground design of the pre-embedded steam pipe 13 effectively reduces heat loss during transportation and avoids the risk of wear or external damage that might occur from exposed pipelines. This design makes full use of steam resources and achieves efficient collaborative work among multiple curing chambers, making it particularly suitable for the needs of large-scale production lines. By rationally arranging the positions of the transportation pipelines and the steam generator 8, it is ensured that each curing chamber can quickly and uniformly obtain the required steam, providing a reliable guarantee for the curing of the beam and reducing the overall operating cost of the steam system.

[0031] In this embodiment, the beam-moving curing chamber also includes a steering system. This system employs a pulley steering device, a lateral transfer trolley, a translation crane, a turnout switch, or a longitudinal and transverse wheel steering device to smoothly transfer the curing chamber from one longitudinal track to another. The steering system design makes switching between multiple production lines more flexible and efficient. The use of multiple steering methods, such as pulley steering devices and translation cranes, allows for the selection of the most suitable transfer method based on the actual work site and requirements, thereby improving equipment adaptability and reducing time consumption and operational complexity during the steering process.

[0032] In this embodiment, the movable steam curing chamber also includes an intelligent system. This intelligent system comprises an obstacle avoidance system, a limit system, and a warning system. The obstacle avoidance system detects obstacles and transmits obstacle information back to the control module. The limit system ensures the steam curing chamber stops moving when it reaches a predetermined area and prevents derailment. The warning system issues warning signals during the movement and curing process. The addition of the intelligent system makes the operation of the steam curing chamber more automated and safer. The obstacle avoidance system can monitor obstacles in the movement path in real time and send data to the control module in advance to adjust the movement path and prevent collisions. The limit system ensures the steam curing chamber stops precisely when it reaches the preset position, avoiding excessive movement or derailment. The warning system includes an audible and visual alarm device that issues warning signals to the surrounding environment during the movement and curing process, alerting staff and improving operational safety.

[0033] The process of using the steam curing chamber in this embodiment is as follows: After the steam curing chamber is assembled, the lower connecting component 2 is connected to the fixed base 4, and then the front and rear doors are closed to form a closed space. The lower connecting component 2 is driven by the electric cylinder 3 to achieve a tight fit with the fixed base 4, ensuring a completely sealed curing environment and preventing steam leakage. After connecting multiple steam connection pipes 9 through the connector 10, the steam generator 8 is turned on, allowing steam to be delivered into the steam curing chamber through the steam connection pipes 9. The steam is rapidly diffused throughout the steam curing chamber through the pipes 11 and the evenly arranged nozzles 12, filling the steam curing chamber with steam. Real-time monitoring by the temperature and humidity monitor and the external display device ensures that the temperature and humidity in the steam curing chamber are always maintained within the specified range, usually controlled at the specified curing temperature and humidity levels, and maintained for 8-10 hours of steam curing time. The monitoring data of the sensor system can be displayed intuitively on the external display device, allowing operators to adjust the steam supply in real time to ensure that the beam concrete quickly reaches the design strength. Once the designated time has elapsed, the steam generator 8 is shut off, the front and rear doors are opened, and simultaneously, the connection between the lower connecting component 2 and the fixed base 4 is disconnected via the electric cylinder 3, releasing the seal of the curing chamber. Subsequently, the drive system is activated, and the curing chamber is moved along the track 15 via the power rollers 6, transferring it from the current workstation to the next workstation, preparing for the curing of the next beam. This process simplifies the operation of the curing chamber, improves work efficiency, and avoids the cumbersome operations associated with transporting beams using traditional fixed curing chambers.

[0034] In summary, this utility model discloses a mobile steam curing chamber for bridge beams, comprising a steam curing chamber structural support system, a drive system, and a steam curing system. It forms a closed space by connecting to a fixed platform via a lower connecting component. Steam is evenly delivered into the steam curing chamber using a steam generator and steam connection pipes, achieving rapid steam curing of the bridge beams. The steam curing chamber moves via powered rollers and tracks, and can be flexibly switched to different working positions using a steering system. Simultaneously, an intelligent system is employed to implement obstacle avoidance, limit, and warning functions, improving operational safety and automation. Through its mobile design and uniform steam distribution, this utility model improves the efficiency and quality of bridge beam steam curing, simplifies the operation process, and is applicable to various bridge engineering scenarios, possessing significant practical value.
