Description

Technical Field

[0001] This utility model relates to the field of slope grooving construction, and in particular to a slope grooving device. Background Technology

[0002] Slope grooving refers to the engineering practice of excavating trenches or grooves of specific shapes and sizes on the surface of a slope using mechanical or manual methods. This enhances the stability of the slope structure or provides a foundation for subsequent reinforcement measures. Typical slope grooving construction offers three main benefits: 1. Preventing surface soil and rock slippage, ensuring the safety of roadbeds or buildings; 2. Providing an installation base for reinforcement structures such as anchor bolts and lattice beams; 3. Improving slope drainage conditions and reducing the risk of water erosion.

[0003] Existing slope grooving solutions suffer from problems such as uneven groove depth, poor contour accuracy, and rapid tool wear in practical applications. Especially in heterogeneous rock formations, precise grooving control is difficult to achieve, and construction efficiency is low while costs are high. The root cause is that existing slope grooving devices lack the ability to sense rock hardness in real time when dealing with heterogeneous rock formations, and different rock hardnesses require different drilling strategies. If a constant drilling strategy is used, it is difficult to effectively drill under varying rock hardness conditions, thus compromising the effectiveness of the grooving. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a slope grooving device that can detect the hardness of the slope rock mass in real time during slope grooving construction in heterogeneous rock strata, and then dynamically adjust the drilling strategy.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a slope grooving device, including a hydraulic driver, a baffle frame and a drill bit. The output end of the hydraulic driver is fixedly connected to the baffle frame. The drill bit is set inside the baffle frame. The hydraulic driver drives the drill bit to drill through the baffle frame. The device includes a drilling control system. The drilling control system includes an ultrasonic probe, a vibration sensor and a pressure sensor. The drilling control system is electrically connected to the hydraulic driver and the drill bit.

[0006] Furthermore, the drilling control system includes a lidar and a spray nozzle, which are mounted on the baffle frame.

[0007] Furthermore, the lidar and spray nozzle are positioned between the drill bit and the hydraulic actuator.

[0008] Furthermore, there are four drill bits, and the baffle frame is used to set four cavities for the drill bits. The four cavities are arranged in a grid-like structure, and the drill bits are set in each cavity in a corresponding manner.

[0009] Furthermore, it includes sub-drill bits, which are evenly distributed on the outer periphery of the bottom of the baffle frame.

[0010] Furthermore, the drill bit is a protruding structure that is perpendicular to the bottom of the baffle frame and extends downwards.

[0011] Furthermore, the drill bit is made of polycrystalline diamond composite sheet.

[0012] The beneficial effects of this utility model are:

[0013] I. Dynamic Control of Drilling Strategy: During drilling, ultrasonic probes acquire information on the hardness of the rock mass in front of the drill bit and the presence of obstacles, while vibration and pressure sensors acquire vibration spectrum characteristic data of the drill bit. Subsequently, the drilling control system integrates the rock hardness information and the drill bit vibration spectrum characteristic data to obtain slope rock hardness data and a subsequent optimized drilling strategy. By adjusting parameters such as the drill bit rotation speed and the hydraulic actuator's advance speed, the drilling strategy is dynamically controlled, ultimately achieving uniform trench depth and high profile accuracy. II. Effective Protection of Drill Bit Cutting Tools: When the drilling control system detects an increase in rock hardness in front of the drill bit, it reduces the drill bit rotation speed and increases the pressure applied to the drill bit by the hydraulic actuator, thereby protecting the cutting tools and effectively reducing the problem of rapid tool wear. III. Effective Reduction of Dust Interference During Drilling, Improving Data Acquisition Accuracy: LiDAR uses laser light to irradiate dust and other particulate matter generated during drilling, obtaining scattered light. The drilling control system then calculates the concentration and particle size of the particulate matter based on the changes in the intensity of the scattered light. When the concentration and size of particulate matter may interfere with the acquisition of rock hardness information and drill bit vibration spectrum characteristic data, the drilling control system activates the spray nozzle to reduce dust, effectively reducing the concentration of surrounding particulate matter, thereby improving the accuracy of acquiring rock hardness information and drill bit vibration spectrum characteristic data.

[0014] This invention is particularly applicable to the construction of slope grooving. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the present invention.

[0016] Figure 2 This is a schematic diagram of the baffle frame and drill bit of this utility model.

[0017] The components in the diagram are labeled as follows: hydraulic actuator 1, baffle frame 2, lidar 21, spray nozzle 22, drill bit 3, and sub-drill bit 31. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 2 The slope grooving device shown includes a hydraulic actuator 1, the output end of which is fixedly connected to the top of a baffle frame 2. A drill bit 3 and a sub-drill bit 31 are disposed at the bottom of the baffle frame 2. A laser radar 21 and a spray nozzle 22 are disposed on the baffle frame 2. Specifically, the laser radar 21 and the spray nozzle 22 are disposed between the drill bit 3 and the output end of the hydraulic actuator 1. The ultrasonic probe, vibration sensor, and pressure sensor of the drilling control system can be disposed on the baffle frame 2. The drilling control system is electrically connected to the hydraulic actuator 1 and the drill bit 3.

[0020] The bottom of the baffle frame 2 is square, and there are four cavities at the bottom of the baffle frame 2 for mounting the drill bits 3. The four cavities are arranged in a grid pattern, and each drill bit 3 is mounted in a corresponding cavity. The drill bits 3 are made of polycrystalline diamond composite sheet, and a gradient density layout of 3-4 teeth / cm2 can be selected. During drilling, the output end of the hydraulic actuator 1 applies a downward driving force to the baffle frame 2. This driving force is transmitted to the drill bits 3 through the baffle frame 2 and drives the four drill bits 3 to drill downward. A sub-drill bit 31 is provided on the outer periphery of the bottom of the baffle frame 2. The sub-drill bit 31 is a protruding structure perpendicular to the bottom of the baffle frame 2 and protruding downward. The front end of the protruding structure is a sharp point. The sub-drill bit 31 plays a role in guiding the drill bits 3 to drill smoothly along the drilling direction during the downward drilling process. In addition, during the drilling process, the true three-dimensional coordinate information of the drill bits 3 is determined based on the Beidou positioning coordinate information and laser pulse data information. By comparing the actual three-dimensional coordinate information of drill bit 3 with the design model, the elevation deviation of drill bit 3 is calculated in real time.

[0021] In practical application, the steps are as follows: Step 1: Obtain ultrasonic testing data and vibration spectrum characteristic data of the slope rock mass. Step 2: Process the data obtained in Step 1 to obtain slope rock hardness data. Specifically, an LSTM neural network model can be selected to process the data obtained in Step 1. Step 3: Based on the slope rock hardness data obtained in Step 2, the drilling control system generates optimal operating parameters and controls the drilling pressure parameters of drill bit 3, the rotational speed parameters of drill bit 3, and the propulsion speed parameters of hydraulic drive 1.
