[0056] Example 1

[0057] This embodiment 1 provides a hydraulic tunnel lining trolley, such as Figures 1-11 As shown, the lining trolley includes an automatic rail-feeding traveling device 1, a main frame 2, and an intelligent grouting device 5. The main frame 2 is connected inside the trolley body, providing reliable support for the trolley body. A template device 3 is connected to the outside of the main frame 2. The template device 3 is equipped with a monitoring component for monitoring the real-time pressure of the side template. The monitoring component is electrically connected to an external intelligent control room 8. The intelligent grouting device 5 is connected to the upper part of the template device 3. The grouting port of the intelligent grouting device 5 is equipped with an intelligent flow and temperature monitoring device 403, as well as multiple sets of electrode terminals 502 and grounding terminals 503. When the concrete is filled, the electrode terminals 502 and grounding terminals 503 form a circuit, triggering the liquid level relay 504 to operate. The liquid level relay 504 transmits a signal to the intelligent control room 8, which issues a cavity alarm to the top, realizing precise monitoring of the grouting process and preventing top quality problems. The automatic rail-feeding traveling device 1 is connected to the lower end of the main frame 2, allowing the lining trolley to travel along the hydraulic tunnel.

[0058] Please refer to 1- Figure 5 As shown, the main frame 2 is placed inside the trolley body. The main frame 2 is composed of 6 steel structural members connected together. Every 2 steel structural members form a rigid structure to ensure the overall stability. Each steel structural member includes a bottom beam 201, a column 202, a longitudinal tie rod 203, a diagonal brace 204, a lower crossbeam 205, an upper crossbeam 206, an upper column 207, a platform beam 208, and a small column 209. The bottom beam 201 is located at the bottom and bears and transmits the weight of the entire trolley. The column 202 is vertically installed on the bottom beam 201 and serves to... The main vertical support is provided by the longitudinal tie rod 203, which connects the columns 202 laterally to enhance longitudinal stability. The diagonal brace 204 is connected to the structure at an angle to improve the structure's resistance to lateral forces. The lower crossbeam 205 and the upper crossbeam 206 connect the lower and upper parts of the columns 202 respectively, forming a stable frame together with the columns 202. The upper column 207 further strengthens the support of the upper structure. The platform beam 208 provides a working platform, and the small column 209 is rigidly connected to the top formwork 301 to ensure the stability of the top formwork 301 during construction.

[0059] Meanwhile, the template device 3 connected to the outside of the main frame 2 includes a top formwork 301, an upper side formwork 302, and a lower side formwork 303. The top formwork 301 is located at the top and directly determines the shape and size of the tunnel top lining. It is rigidly connected to the main frame 2 through small columns 209 to ensure stable position during construction. The upper side formwork 302 and the lower side formwork 303 are located on both sides respectively, cooperating with the top formwork 301 to outline the lining contour of the tunnel side. The side formwork through beam 306 serves to connect the upper side formwork 302 and the lower side formwork 303. The main frame 2 is bolted to the side formwork through beam 306 by means of threaded rod 304 and side formwork cylinder 30. This connection method not only makes the template device 3 firmly connected to the main frame 2, but also controls the opening and closing of the side formwork by the extension and retraction of the side formwork cylinder 305, which facilitates the erection and demolding operations during construction. In addition, the template device 3 is also equipped with a monitoring component for real-time monitoring of the side template pressure. The monitoring component converts the pressure signal into a 0-10V electrical signal and transmits it to the PLC signal receiver 801 in the intelligent control room 8. The PLC signal receiver 801 receives these electrical signals in real time and converts them into pressure values, thereby taking corresponding actions in real time and recording and storing the data to ensure construction safety and lining quality.

[0060] Please refer to 1- Figure 5As shown, the aforementioned automatic rail-feeding traveling device 1 includes two sets of traveling devices 11 and an automatic rail-feeding device 12. It is a guide rail structure made of steel and arranged in a counter-facing manner to adapt to the complex road conditions of the lining working face and meet the movement requirements of the lining trolley. The traveling device 11 is connected to the bottom beam 201 of the lining trolley and includes multiple sets of active traveling devices 111, multiple sets of passive traveling devices 112, and multiple sets of parking devices 113. The active traveling devices 111 are powered by electric motors, which drive the wheels to rotate and provide driving force for the movement of the lining trolley. The passive traveling devices 112 are not powered and rely on their subordinate relationship with the active traveling devices 111 to move in coordination and assist the trolley to move smoothly. The parking device 113 is located between the active and passive traveling devices and consists of 8 sets of foundation jacks. It is electrically connected to the PLC controller 13. When the trolley reaches the construction position, it will descend to the ground and lift the trolley to make the trolley parked stably and prevent displacement during construction.

[0061] Meanwhile, the automatic rail feeding device 12 is respectively set in front of the active walking device 111 and behind the passive walking device 112, and is electrically connected to the PLC controller 13. It automatically moves the track 14 to the designated area, realizes the automatic laying of the track, reduces manual operation, and improves construction efficiency. In this embodiment, the automatic rail feeding device 12 is the prior art, including 4 sets of rail lifting devices. The rail lifting device consists of a rail gripping device, a lifting cylinder, and a rail moving device, all of which are electrically connected to the PLC controller 13. In use, firstly, the rail gripping device on one side grips the track 14, the lifting cylinder lifts the rail gripping device, the rail moving device moves the track 14 to the next working position, the lifting cylinder lowers the rail gripping device, and the rail gripping device lowers the track 14 to the ground, completing the automatic rail feeding work on one side. The other side performs the automatic rail feeding work according to the same steps. The movement of the track 14 is realized when both sides complete the rail feeding process.

[0062] Please refer to Figures 1-9As shown, the intelligent grouting device 5 is connected to the upper part of the template device 3. The intelligent grouting device 5 is equipped with an intelligent flow and temperature monitoring device 403, installed at the top formwork grouting pipe 501. This device can monitor the flow rate and temperature of the concrete in real time during grouting. Flow monitoring allows for precise control of the grouting volume, preventing insufficient or excessive grouting. Temperature monitoring ensures the concrete is in the appropriate condition during construction, guaranteeing grouting quality. The intelligent grouting device 5 also has multiple sets of electrode terminals 502 and grounding terminals 503. When the top is filled with concrete, the electrode terminals 502 and grounding terminals 503 form a circuit, triggering the liquid level relay 504. The liquid level relay 504 transmits a signal to the intelligent control room 8, achieving precise monitoring of the grouting completion status. Furthermore, the intelligent grouting device 5 includes a top crack sensor 504, which constantly monitors the top condition. Once a crack is detected, the top crack sensor 504 forms a circuit with the grounding terminal 503, promptly feeding back to the intelligent control room so that construction personnel can quickly take remedial measures to prevent the quality problem from worsening.

[0063] In summary, the main frame 2 of this embodiment provides support for the trolley, the template device 3 is not only used for lining formation, but also monitors the pressure of the side templates through monitoring components to ensure construction safety and quality, and the intelligent grouting device 5, with its intelligent flow and temperature monitoring device, electrode terminals, etc., achieves precise monitoring of the grouting process to prevent top quality problems. In addition, the automatic rail-feeding walking device 1 ensures the stable movement of the trolley in the tunnel, improving the level of intelligence, construction efficiency and quality of hydraulic tunnel lining construction.

[0064] Example 2

[0065] To further improve intelligent construction management and construction management efficiency, this embodiment 2 provides a hydraulic tunnel lining trolley based on the structure of embodiment 1, such as... Figures 1-11 As shown, this embodiment also includes a fabric unloading device 4, an intelligent vibration device 6, and an intelligent monitoring device 7;

[0066] Please refer to Figures 7-8As shown, multiple sets of concrete placing and unloading devices 4 are installed and connected inside the main frame 2. Each set of concrete placing and unloading devices 4 is equipped with a concrete pump 401, which is located on the top platform 402 of the main frame 2 and connected to the concrete supply source through pipelines. It can provide strong power for the transportation of concrete, and quickly transport concrete from the mixing plant or storage equipment to the construction site. An intelligent flow and temperature monitoring device 403 is also installed at the inlet of the concrete placing and unloading device 4. It can monitor the flow and temperature of the incoming concrete in real time. Flow monitoring can ensure a uniform and stable supply of concrete and avoid insufficient or excessive supply. Temperature monitoring can help to grasp the performance status of the concrete in a timely manner. These data are transmitted to the intelligent control room 8, which allows the operators to adjust the construction parameters according to the actual situation, thereby improving the quality of concrete pouring and ensuring the smooth progress of the entire hydraulic tunnel lining construction.

[0067] In this embodiment, the intelligent flow and temperature monitoring device 402 monitors the real-time flow of concrete using a flow meter 403. Based on Faraday's law of electromagnetic induction, it works by measuring the induced electromotive force generated when concrete moves in a magnetic field and cuts magnetic lines of force. The induced electromotive force is proportional to the flow velocity, enabling the intelligent flow and temperature monitoring device to measure the flow of concrete in a closed pipe. The intelligent flow and temperature monitoring device 402 monitors the real-time temperature of concrete using a resistive sensor 404. When the temperature changes, the resistance of the element changes accordingly. Based on this principle, the temperature can be measured. When the temperature and humidity sensor is powered on, a 0-20mA current or a 0-10V voltage signal is obtained. These signals can be converted into actual temperature and humidity data by the PLC receiver 82 in the intelligent control room 8.

[0068] Please refer to Figure 1 and Figure 10 As shown, the intelligent vibration device 6 is placed inside the formwork device 3 and consists of an attached vibrator 601, a PLC controller 13, and an elevation measuring device 602. The PLC controller 13 is placed to the left of the attached vibrator 601 and is configured to collect the concrete elevation signal measured by the elevation measuring device. It issues control vibration commands in a timely manner according to different elevation signals. The elevation measuring device 602 is placed inside the sealing formwork of the formwork device 3 and is configured to measure the concrete elevation. During use, the vibration process is carried out layer by layer according to the pouring progress. As the concrete in the formwork gradually rises, the concrete elevation measuring device 602 converts the signal into a DC24V signal and transmits the signal to the PLC signal receiver 801 in the intelligent control room 8. The PLC signal receiver 801 in the intelligent control room 8 adjusts the vibration parameters according to the status and records the start and end times of each vibration on the intelligent control room 8 to archive and retain the data. The records can be retrieved at any time when needed.

[0069] Please refer to Figure 1As shown, the intelligent monitoring device 7 is placed inside the upper mold 302 and the main frame 2. It consists of a monitor, a 5G signal receiver, and a safety warning light. It is electrically connected to the intelligent control room 8 through the 5G signal transceiver 802. It is used to monitor the working conditions of the lining working face. The monitor intelligently analyzes the working conditions and safety of each process through the video screen monitored by the monitor. If a violation is detected, the signal receiver will control the safety warning light to emit a safety warning light and transmit the violation image to the intelligent control room 8.

[0070] In summary, each device interacts with the intelligent control room 8 via electrical connection. The PLC signal receiver 801 in the intelligent control room 8 receives data from each device, enabling intelligent construction management and improving construction management efficiency.

[0071] Usage process description:

[0072] The automatic track-feeding traveling device 1 is activated. The active traveling device 111, driven by a motor, drives the passive traveling device 112, causing the lining trolley to move along the track to the designated construction position. During the movement, the intelligent monitoring device 7 observes the trolley's movement in real time to ensure smooth and deviation-free movement.

[0073] Upon reaching the construction location, the parking device 113 lowers, lifting and securing the trolley to prevent displacement during construction. Simultaneously, under the control of the PLC controller 13, the automatic rail feeding device 12 moves the rail 14 required for subsequent construction to a suitable position, preparing for the trolley's next movement.

[0074] The concrete pump 401 of the placing and unloading device 4 is turned on, and the concrete is transported to the formwork device 3 through the pipeline. The intelligent flow and temperature monitoring device 403 at the inlet monitors the concrete flow and temperature in real time, and the data is transmitted to the intelligent control room 8. If the flow or temperature is abnormal, the operator will adjust the concrete supply in time.

[0075] During the concrete pouring process, the concrete elevation measuring device 602 of the intelligent vibration device 6 measures the concrete elevation in real time, and the data is transmitted to the PLC controller 13. The PLC controller 13 controls the attached vibrator 601 to work according to the elevation signal. Different vibration frequencies and times are used in the early stage of concrete pouring and at different heights to ensure that the concrete is vibrated evenly and densely, and to avoid quality problems such as honeycomb and pitted surface.

[0076] The monitoring components in template device 3 monitor the side template pressure in real time, and the data is continuously transmitted to the intelligent control room. Once the pressure approaches or exceeds the set threshold, the intelligent control room 8 issues an alarm, and the operator adjusts the side template cylinder pressure according to the instructions to change the template support force and prevent the side template from deforming or bursting.

[0077] The intelligent grouting device 5 is activated when the concrete pouring is close to the top. The intelligent flow and temperature monitoring device 403 at the grouting port monitors the grouting flow and temperature to ensure grouting quality. When the top concrete is full, the electrode terminal 502 and the grounding terminal 503 form a circuit, triggering the liquid level relay to send a top full signal to the intelligent control room 8. The top crack sensor 505 continuously monitors the top lining condition. If a crack is detected, it forms a circuit with the grounding terminal 503. After receiving the signal, the intelligent control room 8 issues an alarm, and the construction personnel take timely repair measures, such as local grouting reinforcement.

[0078] The intelligent monitoring device 7 collects real-time images of the construction area and transmits them to the intelligent control room 8 via the 5G signal transceiver 802. Operators in the intelligent control room 8 can monitor the construction progress in real time. If any unauthorized operation or equipment malfunction is detected, an alarm will be triggered by controlling the safety warning lights to alert on-site personnel.
