Description

Technical Field

[0001] The present invention relates to the technical field of shield machines, and specifically to an intelligent sensing tool system for shield machines in areas with high water pressure and strong karst development. Background Technique

[0002] The shield method is a method for tunnel excavation and lining construction using a shield machine. A shield machine is a special-purpose machine integrating functions such as excavation, soil retaining, soil discharging, transportation, and lining installation, with a powerful support capacity, and is suitable for tunnel projects with complex geological conditions, busy ground traffic, and high requirements for surface settlement control.

[0003] When shield construction is carried out in areas with high water pressure and strong karst development, highly viscous impurities such as mud and stone powder are extremely likely to adhere to the surface of the tools. These impurities will not only accelerate tool wear but may also block the detection holes of the tool sensors, resulting in distorted tool wear monitoring data, and further leading to tool overload damage or misjudgment of tunneling parameters. However, most of the cleaning devices in existing shield machine tools adopt fixed nozzles or one-way swing designs, and the spraying angle only covers a partial area of the tool, unable to fully cover key parts such as the cutting edge, back, and sensor installation holes of the tool, thus resulting in a small cleaning range and reducing the cleaning efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent sensing tool system for shield machines in areas with high water pressure and strong karst development, which has the advantage of a wide cleaning range and solves the problems raised in the above background technique.

The cleaning mechanism includes a rotating table, the top of the rotating table is fixedly connected with a bottom plate, a placement plate is arranged on the top of the bottom plate, a water tank is fixedly connected to the top of the placement plate, a water inlet pipe is communicated with the top of the water tank, a nozzle is communicated with the front side of the water tank, a first driving mechanism is arranged on the left side of the top of the bottom plate, a second driving mechanism is arranged on the right side of the top of the rotating table, and a connecting rod is fixedly connected to the bottom of the placement plate.

[0006] Further, as a preferred embodiment of the present invention, the first driving mechanism includes a first motor arranged on the left side of the top of the bottom plate, the output shaft of the first motor is fixedly connected with a short rod, the surface of the short rod is sleeved with a first fixing block, the bottom of the first fixing block is fixedly connected with the bottom plate, one end of the short rod is fixedly connected with a first connecting block, the top of the first connecting block is fixedly connected with a limiting plate, and the right side of the bottom of the limiting plate is fixedly connected with a second connecting block.

[0007] Further, as a preferred embodiment of the present invention, the second driving mechanism includes a second motor disposed on the right side of the top of the bottom plate. The output shaft of the second motor is fixedly connected to a long rod. One end of the long rod penetrates into the inner side of the second connecting block. A second fixing block is sleeved on the surface of the long rod. The bottom of the second fixing block is fixedly connected to the bottom plate. A first bevel gear is sleeved on the surface of the long rod. A second bevel gear is fixedly connected to the bottom of the connecting rod.

[0008] Further, as a preferred embodiment of the present invention, mounting seats are sleeved on the surfaces of the first motor and the second motor. Bolts are threadedly connected to the tops of the mounting seats. The first motor and the second motor are detachably connected to the bottom plate through the bolts.

[0009] Further, as a preferred embodiment of the present invention, one end of the long rod is rotatably connected to a support block. The bottom of the support block is fixedly connected to the bottom plate.

[0010] A shield machine intelligent sensing cutter system in a high water pressure karst strongly developed area, comprising:

[0011] S1: Install temperature sensors, pressure sensors and vibration sensors on the cutter head of the shield machine to monitor the working state of the cutters in real time. The sensors are installed at the cutter head positions of the cutters to ensure that relevant data of the cutters can be accurately obtained. Install data acquisition and transmission equipment to timely transmit the data collected by the sensors to the ground monitoring center to ensure its normal operation and accurate setting of various parameters. The alarm threshold of the temperature sensor is 80°C. When the cutter temperature exceeds this value, the system automatically issues an alarm.

[0012] S2: Reasonably set the propulsion speed of the shield machine according to the geological conditions and the cutter state. In the karst developed area, the propulsion speed is controlled at 20 - 40 mm / min. When encountering a karst cavity with a diameter greater than 3 meters, the propulsion speed should be appropriately reduced to 10 - 20 mm / min. When the surrounding rock of the cavity is stable, the rock integrity is strong and the strength is high, the cutter head speed is set at 1.8 - 2.2 r / min. When the surrounding rock of the cavity is unstable, there are broken zones, developed joints and fissures, etc., the cutter head speed is set at 1.2 - 1.6 r / min. Among them, the cutter head speed of the hob can be controlled at 1.5 - 2.5 r / min, and the cutter head speed of the scraper can be controlled at 2 - 3 r / min. At the same time, it is necessary to keep the soil chamber pressure stable and balanced with the groundwater pressure to prevent groundwater from flowing into the shield machine. The soil chamber pressure is controlled at 0.2 - 0.5 MPaa.

[0013] S3: Monitor parameters such as the temperature, pressure, and vibration of the cutter in real time, transmit the data to the ground monitoring center through the intelligent sensing system. The monitoring personnel should closely monitor the working state of the cutter, analyze the collected data using the data analyzer to judge the wear degree and health condition of the cutter. When the temperature of the cutter continues to rise or the vibration amplitude increases, adjust the tunneling parameters in a timely manner or replace the cutter. The wear limit of the hob is 10 - 15 mm, and the wear limit of the scraper is 5 - 10 mm.

[0014] S4: When the shield machine encounters a karst cavity, for a karst cavity with a diameter less than 1 m, use the method of grouting filling for treatment. The grouting material is selected as cement slurry or cement mortar, and the grouting pressure is controlled at 0.5 - 1 MPa. For a karst cavity with a diameter greater than 1 m, use the method of first backfilling with sand and gravel and then grouting for reinforcement. The particle size of the backfilled sand and gravel is controlled at 5 - 20 mm, and the grouting pressure can be appropriately increased and controlled at 1 - 2 MPa.

[0015] Further, as a preferred embodiment of the present invention, in the steps S2 - S3, the propulsion force increases by 10% - 15% compared to the normal state, and the torque increases by 15% - 20%, indicating that the cutter is severely worn.

[0016] Further, as a preferred embodiment of the present invention, in the step S2, during normal tunneling, the vibration acceleration amplitude of the cutter is in the range of 0.5 - 2 m / s 2 range.

[0017] The usage method of the intelligent sensing cutter and cleaning mechanism of the shield machine in the high - water - pressure and strongly karst - developed area includes the following steps:

[0018] Step 1: Transport the external water to the inner cavity of the water tank through the water inlet pipe and finally discharge it through the nozzle to complete the cleaning of the cutter surface;

[0019] Step 2: Start the second motor. The output shaft of the second motor drives the long rod to rotate. When the long rod rotates, it drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the connecting rod to rotate. The connecting rod drives the placement plate to swing left and right, and the placement plate drives the water tank to swing, thereby increasing the spraying range of the nozzle.

[0020] Step 3: Simultaneously start the second motor and the first motor. The output shaft of the first motor drives the short rod to rotate. The short rod drives the first connecting block to move in an arc. The first connecting block drives the limit plate to move. The limit plate drives the second bevel gear and the placement plate to move through the connecting rod. At the same time, the second motor drives the long rod to rotate. The long rod drives the first bevel gear to rotate, so that the second bevel gear will not rotate when moving. The connecting rod drives the placement plate to perform a pitching motion. The placement plate drives the water tank to move, thereby increasing the spraying range of the nozzle again. Start the rotating platform, and the rotating platform can drive the whole to rotate, making the spraying range more comprehensive.

[0021] Beneficial effects: The technical solution of this application has the following technical effects: This invention has the advantage of a wide cleaning range. In the actual use process, by starting the second motor, the placement plate can be driven to swing left and right. The placement plate drives the water tank to swing, so that the nozzle can swing left and right to spray, increasing the spraying range of the nozzle in the horizontal direction. At the same time, when the second motor and the first motor are started simultaneously, the water tank can perform a pitching motion, enabling the nozzle to spray in the pitching direction, and increasing the spraying range of the nozzle again. Starting the rotating platform can drive the entire cleaning mechanism to rotate, making the spraying range of the nozzle more comprehensive. During the rotation, the nozzle can clean the tool from different angles, further expanding the cleaning range, effectively avoiding cleaning blind spots, improving the cleaning effect, and adopting a multi-dimensional swinging cleaning method can cover all areas of the tool surface, ensuring that the tool is cleaned comprehensively and thoroughly.

[0037] The intelligent sensing tool system of a shield machine in a high-water-pressure karst strongly developed area includes:

[0038] S1: Install temperature sensors, pressure sensors and vibration sensors on the cutter head of the shield machine to monitor the working state of the tools in real time. The sensors are installed at the cutter head positions of the tools to ensure that relevant data of the tools can be accurately obtained.

The alarm threshold of the temperature sensor is 80 °C. When the tool temperature exceeds this value, the system automatically issues an alarm.

[0039] S2: According to the geological conditions and tool status, reasonably set the propulsion speed of the shield machine. In the karst development area, the propulsion speed is controlled at 20 - 40 mm / min. When encountering a karst cavity with a diameter greater than 3 meters, the propulsion speed should be appropriately reduced and controlled at 10 - 20 mm / min. When the surrounding rock of the cavity has good stability, strong rock integrity and high strength, the cutter head speed is set at 1.8 - 2.2 r / min. When the surrounding rock of the cavity has poor stability, there are broken zones, developed joints and fissures, etc., the cutter head rotation speed is set at 1.2 - 1.6 r / min. Among them, the cutter head rotation speed of the hob can be controlled at 1.5 - 2.5 r / min, and the cutter head rotation speed of the scraper can be controlled at 2 - 3 r / min. At the same time, it is necessary to keep the soil chamber pressure stable and balanced with the groundwater pressure to prevent groundwater from flowing into the shield machine.

[0040] S3: Real-time monitor parameters such as the temperature, pressure, and vibration of the tools, and transmit the data to the ground monitoring center through the intelligent perception system. The monitoring personnel should closely pay attention to the working status of the tools, analyze the collected data using a data analyzer, and judge the wear degree and health status of the tools. When the temperature of the tools continues to rise or the vibration amplitude increases, adjust the tunneling parameters in a timely manner or replace the tools. The wear limit of the hob is 10 - 15 mm, and the wear limit of the scraper is 5 - 10 mm.

[0041] S4: When the shield machine encounters a karst cavity, for a karst cavity with a diameter less than 1 m, the method of grouting filling is adopted for treatment. The grouting material is selected as cement slurry or cement mortar, and the grouting pressure is controlled at 0.5 - 1 MPa. For a karst cavity with a diameter greater than 1 m, the method of first backfilling with sand and gravel and then grouting for reinforcement is adopted.

[0045] Step 1: Transport the external water through the water inlet pipe 5 to the inner cavity of the water tank 4, and finally discharge it through the nozzle 6 to complete the cleaning of the tool surface.

[0046] Step 2: Start the second motor 81. The output shaft of the second motor 81 drives the long rod 82 to rotate. When the long rod 82 rotates, it drives the first bevel gear 84 to rotate.

[0047] Step 3: Start the second motor 81 and the first motor 71 synchronously. The output shaft of the first motor 71 drives the short rod 72 to rotate. The short rod 72 drives the first connecting block 74 to move in an arc. The first connecting block 74 drives the limiting plate 75 to move.

The placement plate 3 drives the water tank 4 to move, thereby increasing the spraying range of the nozzle 6 again. Start the rotating table 1. The rotating table 1 can drive the whole to rotate, making the spraying range more comprehensive.

At the same time, the second motor (81) drives the long rod (82) to rotate. The long rod (82) drives the first bevel gear (84) to rotate, so that the second bevel gear (85) does not rotate when moving. The connecting rod (9) drives the placing plate (3) to perform a pitching motion. The placing plate (3) drives the water tank (4) to move, thereby further increasing the spraying range of the nozzle (6). Start the rotating platform (1). The rotating platform (1) can drive the whole to rotate, making the spraying range more comprehensive.
