The vibration sensor is a three-axis accelerometer, fixed to the joint of the mechanical arm of the water jet nozzle 31 with a magnetic base, and transmits vibration frequency and amplitude data via a digital interface.

[0036] Furthermore, the water jet system includes: a water jet nozzle 31, installed on the first working part; a laser auxiliary device 32, installed on the first working part, used to focus the laser beam and assist in demolition; a high-pressure water pump, installed in the frame 10, connected to the water jet nozzle 31 through a water pipe, and the high-pressure water pump is communicatively connected to the control unit 20.

[0037] In this embodiment, the water jet nozzle 31 is a hollow, rotating structure, mounted at the end of the robotic arm via a quick-change interface.

The laser-assisted device 32 comprises a fiber optic coupler and a focusing lens assembly. The fiber optic coupler is secured to the rear of the nozzle, with its input connected to a high-power laser within the power compartment of the chassis 10 via an armored optical fiber. The focusing lens assembly is driven by a servo motor and has adjustable focal length to accommodate varying demolition depths. The high-pressure water pump is a plunger-type multistage pump, mounted in the power compartment at the bottom of the chassis 10. Its water inlet is connected to an external water source or a water recovery tank, and its outlet is connected to the water jet nozzle 31 via a high-pressure rubber hose. A pressure sensor and solenoid valve are integrated into the pipeline, and the control unit 20 regulates the water pressure in real time.

[0038] Furthermore, the mechanical drill bit system includes: a demolition drill bit 33, installed on the second working part; a driving device, which is transmission-connected to the demolition drill bit 33 and communication-connected to the control unit 20; a feeding mechanism 34, installed on the frame 10, communication-connected to the control unit 20, and the driving device is installed on the feeding mechanism 34.

The hydraulic pipeline is connected to the hydraulic pump station of the frame 10, and the speed is controlled by a proportional valve. The feed mechanism 34 is a servo electric cylinder, fixed to the vertical guide rail in the middle of the frame 10. The cylinder body is connected to the frame 10 by bolts. The front end of the piston rod is mounted on the drive unit sliding seat, which is rigidly connected to the guide rail slider.

[0041] In this embodiment, the drive wheels 11 are off-road rubber track wheels. Each set of track wheels is equipped with an independent hydraulic motor, which drives the sprocket through a speed reducer. The track surface is equipped with anti-slip ridges to adapt to complex terrain such as mud and gravel. The control mechanism includes a steering hydraulic valve group and a speed controller.

[0043] In this embodiment, the wastewater recovery system consists of an annular collection tank, a filter box and a centrifugal pump. The collection tank is embedded below the demolition area at the front end of the frame 10. The edge of the tank is 50 mm above the ground. The inner wall is covered with an anti-wear coating and is connected to the filter box on the side of the frame 10 through a PVC pipe. The filter box is equipped with three-stage filter screens of 50 μm, 20 μm, and 5 μm, respectively, and an activated carbon adsorption layer. The centrifugal pump is installed at the outlet of the filter box to transport the treated water to the vehicle water tank or the external recovery pool. The spray device is an atomizing nozzle group, which is respectively installed on the edges of the protective cover of the water jet nozzle 31 and the demolition drill bit 33, and is connected to an independent micro water pump through a PE pipe. The water pump is controlled by the control unit 20 relay. The nozzle aperture is 0.5 mm and can form 50-100 μm water mist particles. The dust sensor is a laser dust detector, which is flange-mounted on both sides of the protective cover of the demolition area. The detection range is 0-2000 μg / m 3 , communicates with the control unit 20 via the 485 bus, when the dust concentration exceeds 800μg / m 3 The spray device is automatically triggered when

[0044] like Figure 2 As shown, a method for water-guided laser collaborative demolition of reinforced concrete pile heads based on artificial intelligence recognition includes the following steps:

[0045] Step S1, initial positioning, the control unit 20 sends a coordinate instruction to the speed controller of the mobile chassis, the driving wheel 11 moves the equipment to 1.5m in front of the pile head through differential steering, and then sends a signal to the electric push rod, and the telescopic support rod 12 extends downward until the support wheel is completely in contact with the ground and bears 20% of the weight of the equipment, forming a stable triangular support structure, and the driving wheel 11 and the support wheel form a four-point support.

[0046] Step S2, data acquisition: the laser scanner starts horizontal rotation scanning, and the robotic arm drives the water jet nozzle 31 to move around the pile head to complete the three-dimensional point cloud data acquisition with an accuracy of 0.5mm; the rangefinder synchronously measures the distance between the equipment and each feature point of the pile head to generate a spatial position coordinate system; the industrial camera takes a side image of the pile head and identifies the exposed end points of the steel bars through the edge detection algorithm; the pressure sensor and vibration sensor collect baseline data when the drill bit is idling, which is used for signal comparison during subsequent demolition.

[0047] Step S3, strategy generation: the control unit 20 imports the three-dimensional point cloud data into a pre-trained CNN model. The model is implemented by technicians using existing technologies to identify the strength distribution area of ​​the pile head concrete and generate an obstacle avoidance path based on the steel bar identification results. A genetic algorithm is used to optimize the demolition sequence, and water-guided laser cutting is prioritized for areas with dense steel bars. A spiral drill feed path is planned for the core layer with a hardness greater than C50. At the same time, initial parameters such as water jet pressure of 200 MPa, laser power of 300 W, and drill speed of 300 rpm are set.

[0048] In step S4, collaborative demolition, the robotic arm first drives the water jet nozzle 31 to spray at a 45° angle to peel off the floating slurry layer on the top of the pile head; then the nozzle switches to a vertical posture, the laser auxiliary device 32 is activated, and the focusing lens group adjusts the focal length of the laser beam to 200 mm, forming a high-energy beam with a diameter of 0.3 mm in the water jet, which is melted along the steel bar detection position; when the drill bit contacts the core layer concrete, the feed mechanism 34 advances at a speed of 50 mm / min, and the hydraulic motor feeds back torque data in real time. The control unit 20 dynamically adjusts the feed speed according to the pressure sensor signal. For example, if the torque exceeds 400 N·m, the feed is suspended and the water jet pre-impact is activated.

[0049] Step S5, environmental protection treatment, the wastewater generated by demolition is filtered through the collection tank, and the centrifugal pump delivers it to the vehicle-mounted water tank at a flow rate of 5L / min. When the water level in the water tank reaches 80%, it automatically switches to the external discharge mode; the dust sensor collects data every 2 seconds. When the detection value exceeds the threshold, the spray device is started at intervals of 10 seconds, spraying for 5 seconds each time to form continuous dust reduction protection.

[0050] Step S6, verification and optimization. After the demolition is completed, the robotic arm drives the laser scanner to perform a second scan of the demolition surface, and detects the remaining hard areas through the point cloud data comparison algorithm; the control unit 20 stores the steel bar position, concrete hardness distribution, parameter adjustment records, etc. of this demolition into the database for updating the demolition strategy model and improving the demolition efficiency of subsequent similar working conditions.

[0051] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
