Description

Technical Field

[0001] This utility model relates to the field of tunnels, and in particular to an intelligent steam curing trolley for tunnels. Background Technology

[0002] Traditional tunnel secondary lining concrete curing relies on natural conditions or simple water spraying, making it difficult to effectively control temperature and humidity. Especially in cold, dry, or environments with large temperature differences, concrete is prone to problems such as early freezing, drying shrinkage cracking, and incomplete hydration. Furthermore, in conventional construction, steam curing and spray curing of concrete are often carried out in stages by different equipment or manual labor. Limited space in tunnel construction makes equipment difficult to rotate, leading to poor workflow and increasing the risk of concrete cracking. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the prior art, such as early freezing, drying shrinkage cracking, and insufficient hydration of secondary lining concrete in tunnels in high-altitude or cold regions. At the same time, in conventional construction, steam curing and spray curing are often carried out in stages by different equipment or manual labor. Due to the limited space in tunnel construction and the difficulty in equipment turnover, the process is not smooth and the risk of concrete cracking is increased. The present invention provides a tunnel intelligent steam curing trolley.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tunnel intelligent steam curing trolley includes a trolley frame, a sealing system, a steam system, an atomization system, and several temperature and humidity sensors. The trolley frame includes a steel arch and supporting swing rods, with the supporting swing rods rotatably connected to both sides of the steel arch. The sealing system includes end-sealing airbags and a circumferential sealing curtain. The end-sealing airbags are located at the front and rear ends of the trolley frame, and the circumferential sealing curtain is laid along the circumferential surface of the steel arch and the outer side of the supporting swing rods. The front and rear ends of the circumferential sealing curtain are connected to the end-sealing airbags. The supporting swing rods can move the bottom end of the circumferential sealing curtain closer to or further away from the secondary lining, and the end-sealing airbags can expand and fit against the secondary lining. The steam system includes a steam generator and steam nozzles. The steam generator is mounted on the trolley frame, and the steam nozzles are connected to the steam generator. The steam nozzles are located between the circumferential sealing curtain and the secondary lining, with a plurality of steam nozzles spaced at intervals along the height direction of the supporting swing arm. The atomization system includes an atomizing generator and atomizing nozzles. The atomizing generator is mounted on the trolley frame, and the atomizing nozzles are connected to the atomizing generator. The atomizing nozzles are located between the circumferential sealing curtain and the secondary lining, with a plurality of atomizing nozzles spaced at intervals along the circumferential direction of the trolley frame. The temperature sensor and humidity sensor are connected to the trolley frame and located between the circumferential sealing curtain and the secondary lining.

[0005] The tunnel intelligent steam curing trolley described in this utility model utilizes a support swing rod that rotates around a steel arch frame to attach the bottom end of the circumferential sealing curtain to the secondary lining. The end sealing airbag is then inflated and attached to the secondary lining, forming a stable, sealed cavity. Temperature and humidity sensors detect the temperature and humidity within the sealed cavity. When the temperature is below a set level, steam is generated by the steam generator and sprayed into the sealed cavity through the steam nozzles to steam-cur the secondary lining concrete. When the temperature or humidity in the sealed cavity is too high or too low, the steam system is shut off, and spray curing is performed through the atomizer and atomizer nozzles to regulate the curing temperature and humidity. This tunnel intelligent steam curing trolley has a simple structure, with all functions integrated into the trolley frame. It allows for quick switching of curing modes, eliminates the need for equipment maneuvering, is easy to use, and ensures smooth workflow, effectively curing the secondary lining concrete.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This utility model discloses an intelligent steam curing trolley for tunnels. The trolley rotates around a steel arch frame via a supporting swing rod, allowing the bottom end of a circumferential sealing curtain to adhere to the secondary lining. An end-sealing airbag is then inflated and adhered to the secondary lining, forming a stable, sealed cavity.

[0024] In related technologies, secondary lining concrete in tunnels located in high-altitude or frigid regions is prone to problems such as early freezing, drying shrinkage cracking, and insufficient hydration. Furthermore, in conventional construction, steam curing and spray curing are often performed in stages by different equipment or manually. Limited space in tunnel construction makes equipment difficult to maneuver, leading to poor workflow and increasing the risk of concrete cracking. Therefore, the technical solution of this application was developed. The following section combines... Figures 1 to 4 To elaborate.

[0025] Example 1 like Figures 1 to 4 As shown, the intelligent steam curing trolley for tunnels of this utility model includes a trolley frame 1, a walking system 3, a sealing system 4, a steam system 5, an atomization system 6, a water tank 8, a main control system, and several temperature sensors and humidity sensors 7.

[0026] like Figure 1 As shown, the trolley frame 1 includes a steel arch frame 11, a support swing rod 12, a hydraulic rod 13, a platform 14, and a ventilation pipe frame 15. The support swing rod 12 is rotatably connected to both sides of the steel arch frame 11. Optionally, the upper end of the support swing rod 12 is rotatably connected to the waist of the steel arch frame 11. One end of the hydraulic rod 13 is rotatably connected to the lower end of the steel arch frame 11, and the other end is rotatably connected to the lower end of the support swing rod 12. The hydraulic rod 13 is connected to a hydraulic oil tank, which is located on the steel arch frame 11. The platform 14 is located at the middle of the height direction of the steel arch frame 11, and both ends of the platform 14 are connected to the steel arch frame 11. The ventilation pipe frame 15 is connected to the lower part of the top of the steel arch frame 11, and a ventilation pipe 2 is installed on the ventilation pipe frame 15. The steel arch frame 11 is composed of multiple standard units, and the curvature of the steel arch frame 11 is adapted to the curvature of the inner surface of the secondary lining of the tunnel.

[0027] like Figure 1 and Figure 2As shown, the sealing system 4 includes an end sealing airbag 41, a circumferential sealing curtain 42, an inflation pump, and a deflation valve. The end sealing airbag 41 is located at both ends of the trolley frame 1. The inflation pump and the deflation valve are both located on the steel arch frame 11 and are connected to the end sealing airbag 41. The circumferential sealing curtain 42 is laid along the circumferential surface of the steel arch frame 11 and the outer side of the support swing rod 12. The front and rear ends of the circumferential sealing curtain 42 are connected to the end sealing airbag 41. The support swing rod 12 can move the bottom end of the circumferential sealing curtain 42 closer to or further away from the secondary lining, and the end sealing airbag 41 can expand and fit against the secondary lining. In an optional embodiment, the sealing system 4 also includes a pressure sensor located inside the end sealing airbag 41 to detect the internal pressure of the end sealing airbag 41. In an optional embodiment, the circumferential sealing curtain 42 can be made of rubber or airtight sponge material.

[0028] During maintenance, the hydraulic rods 13 on both sides of the trolley frame 1 extend and drive the support swing rod 12 to rotate and unfold around the steel arch frame 11. The support swing rod 12 drives the bottom end of the circumferential sealing curtain 42 to fit into the secondary lining. The air pump inflates the end sealing airbag 41, causing the end sealing airbag 41 to expand and fit into the secondary lining. A stable sealed cavity is formed between the end sealing airbag 41, the circumferential sealing curtain 42, and the secondary lining.

[0029] After maintenance, the end sealing airbag 41 is vented through the vent valve. The end sealing airbag 41 contracts, and the hydraulic rods 13 on both sides of the trolley frame 1 retract, driving the support swing rod 12 to rotate around the steel arch frame 11 and move closer. The support swing rod 12 drives the bottom end of the circumferential sealing curtain 42 away from the secondary lining, avoiding damage caused by the sealing system 4 rubbing against the secondary lining when the trolley frame 1 moves.

[0030] like Figure 1 As shown, the water tank 8 is installed on the steel arch frame 11, and the water tank 8 is equipped with a filter. Water is sent into the water tank 8 through the filter, which can adapt to the complex water source conditions at the construction site.

[0031] like Figure 3As shown, the steam system 5 includes a steam generator 51, a steam pipeline 52, and steam nozzles 53. The steam generator 51 is mounted on the trolley frame 1 and connected to the water tank 8. The steam nozzles 53 are connected to the steam generator 51 through the steam pipeline 52 and are located between the circumferential sealing curtain 42 and the secondary lining. Several steam nozzles 53 are spaced apart along the height direction of the support swing rod 12. In an optional embodiment, the steam generator 51 is an industrial steam generator with automatic water supply and temperature self-regulation functions. The steam system 5 can be used without manual intervention throughout the entire process. When the temperature inside the sealed cavity is lower than the set temperature, the steam system 5 starts and injects steam into the sealed cavity to regulate the curing temperature and humidity.

[0032] like Figure 4 As shown, the atomization system 6 includes an atomizer 61, an atomization pipe 62, and atomizing nozzles 63. The atomizer 61 is mounted on the platform 14. The atomizing nozzles 63 are connected to the atomizer 61 through the atomization pipe 62. The atomizer 61 is connected to the water tank 8. The atomizing nozzles 63 are located between the circumferential sealing curtain 42 and the secondary lining, with a plurality of atomizing nozzles 63 spaced circumferentially along the trolley frame 1. The temperature sensor and humidity sensor 7 are connected to the trolley frame 1 and located between the circumferential sealing curtain 42 and the secondary lining. In an optional embodiment, the atomizer 61 uses an industrial-grade ultrasonic atomizing product, with a water droplet diameter of no more than 5 micrometers, providing wide atomization coverage and uniform spraying. When the temperature inside the sealed cavity is too high or the humidity is too low, the atomization system 6 will activate to spray atomized water into the sealed cavity, adjusting the curing temperature and humidity to ensure that the temperature difference between the sprayed atomized water and the surface temperature of the secondary lining concrete is within a controlled range. In an optional embodiment, the circumferential sealing curtain 42 is provided with at least one observation window 9 for observing the curing condition inside the sealed cavity.

[0033] like Figure 1 As shown, the walking system 3 is connected to the bottom of the steel arch frame 11. Figure 2 As shown, the walking system 3 includes a front walking wheel mechanism 31, a rear walking wheel mechanism 32, and a steering mechanism 33. The steering mechanism 33 connects to and drives the wheels of the front walking wheel mechanism 31 to turn. Figure 2 The direction of the middle arrow indicates the forward direction of the trolley. The walking system 3 uses all-wheel drive, where the two front wheels are both drive wheels and steering wheels.

[0034] The main control system includes a main control console and a monitor. The main control console is electrically connected to the monitor, the hydraulic rod 13, the air pump, the air release valve, the steam generator 51, the atomizing generator 61, and the temperature sensor and humidity sensor 7. The main control console is an industrial computer or a PLC, and the monitor includes a video monitor.

[0035] This embodiment describes a tunnel intelligent steam curing trolley. The supporting swing rod 12 rotates around the steel arch frame 11, causing the bottom end of the circumferential sealing curtain 42 to adhere to the secondary lining. The end sealing airbag 41 is inflated and adheres to the secondary lining, forming a stable, sealed cavity. Temperature and humidity sensors 7 detect the temperature and humidity within the sealed cavity. When the temperature is lower than the set temperature, steam is generated by the steam generator 51 and sprayed into the sealed cavity through the steam nozzle 53 for steam curing of the secondary lining concrete. When the temperature or humidity in the sealed cavity is too high or too low, the steam system 5 is shut off, and spray curing is performed through the atomizing generator 61 and the atomizing nozzle 63 to regulate the curing temperature and humidity. This tunnel intelligent steam curing trolley has a simple structure, with all functions integrated into the trolley frame 1. It allows for quick switching of curing modes, eliminates the need for equipment maneuvering, is easy to use, and ensures smooth process connections, effectively curing the secondary lining concrete.
