Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of trolleys, and in particular to a closed intelligent maintenance trolley for tunnels. Background Art
[0002] With the development of concrete technology, concrete performance has been significantly improved. However, the harsh construction environment of tunnels leads to large early-stage autogenous shrinkage and high cracking sensitivity, making it prone to cracking. This damage becomes increasingly apparent during service, causing severe economic losses. This is primarily due to concrete's poor durability, the lack of scientific early-stage curing methods, improper curing, and low curing efficiency. Curing is a crucial step in achieving high-quality concrete and significantly impacts its performance development. After pouring, the concrete mixture must be cured in a suitable environment during the initial hardening phase to ensure the proper performance of the concrete.
[0003] Three key factors influence concrete curing: curing temperature, curing humidity, and curing time. These factors influence concrete performance, particularly near the surface. Tunnels are complex, with large concrete areas and caverns. Curing the vault and haunch is challenging, and maintaining the correct humidity and temperature is difficult, consuming significant labor and time. The enclosed intelligent curing trolley is a specialized tunnel curing device developed to address the challenges of tunnel secondary lining curing. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A closed intelligent maintenance trolley for a tunnel comprises a trolley body, the outer wall of the trolley body is provided with a plurality of temperature and humidity sensors, the outer wall of the trolley body is provided with a plurality of spray pipes, ultrasonic atomization pipes and high-pressure steam rubber hoses, the spray pipes, ultrasonic atomization pipes and high-pressure steam rubber hoses are used for maintaining the tunnel, the spray pipes, ultrasonic atomization pipes and high-pressure steam rubber hoses are provided with a plurality of nozzles, the interior of the trolley body is provided with a plurality of first longitudinal connecting beams and second longitudinal connecting beams, both sides of the bottom of the trolley body are provided with a moving mechanism for a moving device, the moving mechanism comprises a drive motor and moving wheels, the drive motor is used to control the movement of the moving wheels, and the interior of the trolley body is provided with a control component for controlling the maintenance process;
[0007] A heating mechanism is provided inside the trolley body, and the heating mechanism is used to heat water.
[0008] In one possible design, the control component includes an intelligent control box and a main distribution box, which are electrically connected. The intelligent control box and the main distribution box are both arranged inside the trolley body, and also include a hydraulic station, a moving mechanism and multiple steam generators, which are all electrically connected to the main distribution box.
[0009] In one possible design, the control component also includes a sensor mechanism, a high-pressure water pump, multiple heating mechanisms and multiple ultrasonic humidifiers, and the sensor mechanism, high-pressure water pump, multiple heating mechanisms and multiple ultrasonic humidifiers are all electrically connected to the main distribution box. It also includes multiple water buckets, and the water buckets are equipped with liquid level sensors electrically connected to the main distribution box.
[0010] In one possible design, the heating mechanism includes a constant temperature water tank, which is connected to the fog maker through a high-pressure steam rubber tube, and the constant temperature water tank is connected to the water bucket through a transparent steel wire hose.
[0011] In one possible design, a sewage outlet is provided on the constant temperature water tank, a constant temperature electric heater is provided inside the constant temperature water tank, a heating tube is fixedly connected to one end of the constant temperature water tank, the heating tube cooperates with the constant temperature electric heater, a sewage outlet is provided on the top of the constant temperature water tank, a protective cover is provided at one end of the constant temperature water tank, and the protective cover is used in conjunction with the heating tube.

[0014] In this application, an integrated information-based computer control system enables intelligent and automated maintenance. Multiple temperature and humidity sensors monitor maintenance conditions in real time, enabling full-process data collection, control, recording, storage, and transmission of parameters such as temperature, humidity, and time, with the ability to export these data into reports. Intelligent control and adjustment of temperature and humidity within the maintenance area is achieved through program settings.
[0015] 2. Constant temperature spray system, which consists of a heating device, a pressurizing device, a spray pipeline, etc. The heating device can heat the water to the set temperature, and automatically heat it if the temperature is too low to achieve a constant temperature spray effect.
[0016] 3. The spray pipe adopts quick connector, which is convenient for disassembly and assembly, saving installation time on the construction site and reducing installation difficulty.
[0017] 4. The spray pipeline is 12 meters long and has 23 nozzles in each row. The nozzle angle can be adjusted arbitrarily within the circumferential range of 180°.
[0018] 5. The equipment is equipped with 4 high-power steam systems with a maximum power of 216kW, which can quickly generate steam within 10 minutes, quickly increase the temperature in the curing area in a short time, and ensure the curing temperature in a low temperature environment.
[0019] 6. Intelligent temperature control: Through the intelligent control of the spray system and the steam system, the temperature of the maintenance area is kept within the set temperature range. Multiple temperature and humidity sensors are set on the trolley, so that the two systems can run alternately according to the set temperature range to achieve the temperature control effect. When the temperature is too low, the high-temperature water vapor generated by the steam system heats the ambient temperature; when the temperature is too high, the steam system stops running and the spray system starts working. The lower temperature of the spray water plays a cooling role.
[0020] 7. The ultrasonic atomization system uses an industrial-grade humidifier. Through the ultra-high frequency resonance of the atomizer, water is thrown off the surface to produce a naturally flowing mist. Without the need for heating or chemicals, 3-5μm water particles float in the air, achieving a humidifying effect. A single humidifier can produce up to 70kg / h of atomization.
[0021] 8. The humidification system has no mechanical drive, no noise, and high atomization efficiency (close to 100%).
[0022] 9. Humidity control: the humidification system automatically starts and stops according to the humidity on site to ensure the ambient humidity.
[0023] 9. Humidification with temperature; the heating water tank is connected to the humidifier to provide hot water source for the humidifier to prevent water mist from lowering the ambient temperature.
[0024] 10. Multi-point detection and automatic control eliminate the need for human supervision during the maintenance process. The equipment is equipped with 9 temperature and humidity sensors, 2 temperature sensors, and 1 liquid level gauge. It automatically coordinates and controls various systems based on the detection data, including water addition, heating / cooling, and humidification.
[0025] 11. A valve is installed at the water inlet of the water tank, which will be closed when the water is full and opened when water is used, so as to achieve the effect of continuous automatic water replenishment.
[0026] 12. Water shortage protection: a liquid level gauge is installed in the water tank. When the external water source is cut off and the water level in the tank is too low, all equipment will automatically stop.
[0027] Beneficial effects: 1. The gantry structure is designed with brackets on the columns, eliminating the ordinary gantry diagonal braces and increasing the space for equipment to pass under the gantry.
[0028] 2. The upper cross beam of the trolley is integrally welded with the bracket in a trapezoidal shape, thereby increasing the overall rigidity of the portal and reducing the installation workload.
[0029] 3. Multiple observation windows are arranged on the trolley, which, in combination with the walkway platform, facilitate personnel to observe the maintenance state, detect the concrete quality and maintain the pipeline.
[0030] 4. The trolley walking, translation and jacking are designed as a whole, compared with the traditional separated design, the design can make the front end positioning more flexible, realize the up-down, left-right and front-back overall adjustment, achieve zero lap joint with the secondary lining trolley, and solve the problems of difficult and slow connection of the maintenance and the secondary lining.
