Description

Technical Field

[0001] This utility model relates to the field of tunnel maintenance technology, and in particular to a tunnel digital spray maintenance trolley. Background Technology

[0002] As is widely known, in tunnel construction, the curing of concrete lining is a crucial step in ensuring its final strength, durability, and overall quality. Currently, this field generally relies on traditional manual handheld spraying equipment for curing operations, which has several inherent drawbacks: First, the timeliness and continuity of maintenance are difficult to guarantee. The tunnel construction environment is complex and the tasks are heavy. Maintenance workers cannot strictly follow the established maintenance time nodes. Especially in large tunnel projects, the limited number of maintenance personnel are responsible for extremely long working faces. Often, the interval between spraying is too long, making it impossible to provide a continuous and stable water supply during the critical stage of early strength growth of concrete. Second, the uniformity of curing is poor and the quality cannot be controlled. Manual operation is subject to the personal habits, physical strength and skill of the workers, which leads to the extreme instability of the spraying range, water volume and pressure, resulting in uneven distribution of water on the lining surface and uncontrollable curing quality. Third, the level of intelligence is low, and the labor costs are high and the efficiency is low. The entire maintenance process requires a large amount of labor, which not only significantly increases the project cost, but also makes it easy for manual operation to lead to a decline in quality due to fatigue and oversight, further reducing the consistency of work efficiency and results.

[0003] In addition, the existing maintenance equipment has poor deployment flexibility, which affects the construction period; some large spraying equipment requires complex on-site installation and commissioning after arriving at the construction site, which often takes a long time and delays the timely commencement of maintenance work, thus affecting the overall project progress; therefore, there is an urgent need in this field for a tunnel lining maintenance equipment that can effectively solve the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology and solve the existing technical problems, this utility model discloses a tunnel digital spray curing trolley, which is not only easy to operate and debug, but also can achieve efficient and precise curing of tunnel lining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tunnel digital sprinkler maintenance trolley includes a mobile trolley and a maintenance longitudinal bar located longitudinally above one side of the mobile trolley. A water tank and a water pump are installed on the mobile trolley. Multiple vertical bars are arranged side-by-side on the other side of the trolley. The top of each vertical bar is rotatably connected to a horizontal bar via a first pivot parallel to the maintenance longitudinal bar. A diagonal brace is provided between the horizontal bar and the corresponding vertical bar. One end of the diagonal brace is rotatably connected to the middle section of the corresponding horizontal bar via a second pivot, and the other end of the diagonal brace is connected to the middle section of the corresponding vertical bar via a detachable pin. The maintenance longitudinal bar is erected and fixed to the outer end of the horizontal bar. Multiple rotating nozzles are evenly spaced along the axial direction on the maintenance longitudinal bar. The water tank supplies water to the rotating nozzles via the water pump.

[0006] Furthermore, the spray maintenance trolley also includes a control device. The mobile trolley is equipped with a temperature and humidity sensor and an infrared rangefinder for detecting obstacles. The water tank is equipped with a heating component, a water temperature sensor, and a water level sensor. The control device is connected to the corresponding signals of the mobile trolley, the temperature and humidity sensor, the infrared rangefinder, the heating component, the water temperature sensor, and the water level sensor.

[0007] Furthermore, the control device includes a central processing unit and a control panel, and the control device is connected to the remote monitoring center via a wireless communication module.

[0008] Furthermore, the mobile vehicle includes a lightweight shell, a steel chassis, and four drive wheels driven by high-torque DC motors, the drive wheels being equipped with shock-absorbing devices.

[0009] Furthermore, the rotating nozzle is mounted on the maintenance longitudinal rod via an angle adjustment mechanism.

[0010] Furthermore, the water tank is provided with an inlet and an outlet connected to a water pump via an inserted water pipe, and a water filtration device is installed at the inlet end of the water pipe.

[0011] Furthermore, the diagonal brace is fitted with an elastic protective sleeve, and the lower surface of the outer end of the crossbar is provided with a corresponding groove for the diagonal brace.

[0012] By adopting the technical solution described above, this utility model has the following beneficial effects: The tunnel digital spraying maintenance trolley disclosed in this utility model can move multiple rotating nozzles on the maintenance longitudinal rod flexibly in the tunnel as needed by moving the trolley. Under the control of the water pump, water in the water tank is drawn and sprayed. Compared with manual spraying, it ensures the continuity, timeliness and uniformity of spraying maintenance, greatly reduces labor costs and improves efficiency and quality. More importantly, the spraying maintenance trolley is not only simple in structure and easy to debug and operate, but it can also be folded when not in operation to reduce its width, making it easy to maintain the rotating nozzles and move them.

[0016] Combined with appendix Figure 1-3 The aforementioned tunnel digital spray maintenance trolley includes a mobile trolley 1 and a maintenance longitudinal bar 4 longitudinally positioned above one side of the mobile trolley 1. Depending on the requirements, the mobile trolley 1 includes a lightweight outer shell, a steel chassis, and four drive wheels driven by high-torque DC motors. Each of the four drive wheels is equipped with a high-torque DC motor, capable of adjusting power according to control commands to adapt to different road conditions, such as increasing torque when climbing slopes. Furthermore, the four steering wheels are connected to steering motors via a high-precision universal joint steering mechanism, achieving precise and flexible steering with a very small turning radius, enabling agile movement within the tunnel. The chassis of the mobile trolley 1 is welded from high-strength steel, providing strong load-bearing capacity. The outer shell is made of lightweight, high-strength materials, such as aluminum alloy or high-strength alloy, offering excellent protective performance, preventing dust and moisture from entering and effectively protecting components such as the motor and electrical box. In addition, the drive wheels are equipped with shock-absorbing devices, further optimizing walking performance and equipment stability. The mobile trolley 1 is equipped with a water tank 12 and a water pump 2. Multiple vertical poles 8 are arranged side-by-side on the other side of the mobile trolley 1, as shown in the attached diagram. Figure 2As shown, two vertical rods 8 can be fixed at both ends of the mobile trolley 1. The top of each vertical rod 8 is rotatably connected to a horizontal rod 6 via a first pivot 7 parallel to the maintenance longitudinal rod 4. A diagonal brace 10 is provided between the horizontal rod 6 and the corresponding vertical rod 8. One end of the diagonal brace 10 is rotatably connected to the middle of the corresponding horizontal rod 6 via a second pivot 9. The other end of the diagonal brace 10 is connected to the middle of the corresponding vertical rod 8 via a detachable pin 11. The diagonal brace 10 can increase the connection and support strength of the horizontal rod 6. Moreover, if in the transportation or non-operation state, the pin 11 can be removed and the horizontal rod 6 can be folded to reduce the size of the equipment and facilitate transportation and storage. The maintenance longitudinal rod 4 is erected and fixed to the outer end of the horizontal rod 6. Multiple rotating nozzles 5 are evenly spaced along the axial direction of the maintenance longitudinal rod 4. The length of the maintenance longitudinal rod 4 can be set to 12m. Lightweight and high-strength materials, such as aluminum alloy or high-strength composite materials, are used. Rotary nozzles 5 are reserved at 2m intervals for installation. The rotating nozzle 5 is a pressure atomizing nozzle, which sprays water by impacting the rotating blades with high-pressure water flow. As needed, the rotating nozzle 5 is installed on the maintenance longitudinal rod 4 via an angle adjustment mechanism for easy adjustment of the spray angle. The water tank 12 supplies water to the rotating nozzle 5 via a water pump 2. The water pressure is adjusted by controlling the power of the water pump 2 to precisely control the water volume of the rotating nozzle 5. Specifically, the water tank 12 has an inlet and an outlet connected to the water pump 2 via an inserted water pipe. A water filtration device is installed at the inlet end of the water pipe to filter the water in the water tank 12, remove impurities, prevent clogging of the rotating nozzle 5, and ensure the spraying effect. Furthermore, the water tank 12 is made of welded steel plate with internal anti-corrosion treatment. The inlet is equipped with a sealing device. The capacity of the water tank 12 is designed according to the tunnel maintenance requirements. A high-precision water level sensor is installed inside. The water supply pipeline uses high-pressure and corrosion-resistant materials, such as stainless steel pipes or high-strength plastic pipes, and the connections use joints with good sealing performance.

[0017] As needed, the spray curing trolley also includes a control device 3. The mobile trolley 1 is equipped with a temperature and humidity sensor and an infrared rangefinder for obstacle detection. Specifically, an infrared sensor can be installed under the chassis to detect the distance between the trolley and obstacles on the tunnel wall and ground in real time. When the distance is too close, the deceleration or braking function is automatically triggered to avoid collisions. When the trolley turns or approaches the workers, it automatically switches to warning light mode to improve operational safety. The water tank 12 is equipped with a heating element, a water temperature sensor, and a water level sensor, which are used to heat, measure the temperature, and monitor the water level in the water tank 12, respectively. The control device 3 is connected to the mobile trolley 1, the temperature and humidity sensor, the infrared rangefinder, the heating element, the water temperature sensor, and the water level sensor, respectively. In addition, the control device 3 includes a central processing unit and a control panel. The control device 3 is connected to the remote monitoring center via a wireless communication module. The spray curing trolley has a timed automatic curing function. Users can input parameters such as curing time and spraying duration on the control panel. The central processing unit controls the solenoid valves installed on the water pipes according to the set time. The water tank 12 has temperature detection and automatic heating control functions. The water temperature sensor in the water tank 12 provides real-time feedback on the water temperature. When the water temperature is lower than the appropriate range, the central processing unit starts the heating component. The temperature and humidity sensor collects temperature and humidity data in the tunnel in real time, providing a basis for adjusting the curing strategy. At the same time, the water tank 12 has water level detection, water shortage alarm, and automatic stop curing function when water shortage occurs. The water level sensor provides feedback on the water level. When the water level is lower than the lower limit, the system alarms and automatically stops curing. The control device 3 uses intelligent algorithms to automatically adjust parameters such as spraying water volume and spraying interval time based on information such as tunnel temperature and humidity, water level in water tank 12, and concrete curing time. The control device 3 supports 4G / 5G or Wi-Fi communication and can transmit data with the remote monitoring center to realize remote real-time monitoring of equipment operation status, curing parameters, fault alarms, and other information.

[0018] As needed, the diagonal brace 10 is fitted with an elastic protective sleeve, and the lower surface of the outer end of the crossbar 6 is provided with a corresponding groove for the diagonal brace 10, as shown in the attached figure. Figure 3 As shown, when folding, the end of the diagonal brace 10 that is removed from the pin 11 can rotate and be locked into the slot to prevent it from swinging wildly; the elastic protective sleeve can play a protective role and prevent the moving trolley 1 from being scratched.

[0019] When assembling the tunnel digital sprinkler maintenance trolley described in this utility model on the construction site, the mobile trolley 1 is first positioned as a whole, and the crossbar 6 and diagonal brace 10 are fixed. Then, the sprinkler system pipeline is connected, and the rotating nozzle 5, water pump 2, and water pipes are connected to ensure that the water circuit is unobstructed and sealed. Then, the control system circuit is connected, and various sensors and detection instruments are installed. The entire process can be completed by technicians according to the instructions and with a few common tools, which is simple and quick, shortens the equipment installation time, and reduces the impact on the construction period. When the sprinkler maintenance trolley is debugged and tunnel maintenance is carried out, the operator first positions the mobile trolley 1 to the place that needs to be maintained, ensuring that the rotating nozzle 5 is located at the center line of the tunnel. After setting the maintenance parameters, maintenance can begin, and various parameters are automatically adjusted according to the tunnel environment and its own condition to ensure the quality of maintenance.
