Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering investigation technology, specifically a geotechnical engineering investigation robot. Background Technology

[0002] Geotechnical engineering investigation involves conducting various investigations and studies on the geological conditions of a specific area, including rocks, stratigraphic structures, minerals, groundwater, and landforms. A geotechnical engineering investigation robot is an intelligent robot specifically designed for geotechnical engineering investigation tasks. It emits ultrasonic waves into the soil and rock mass through ultrasonic sensors and measures parameters such as the propagation time, speed, and attenuation of the ultrasonic waves in the soil and rock mass to obtain the physical properties of the soil and rock mass, such as density and elastic modulus. This allows it to determine the compactness and integrity of the soil and rock mass and to perform data collection, analysis, and transmission in various complex geotechnical environments.

[0003] In geotechnical engineering investigation, ultrasonic sensors are one of the key components of geotechnical engineering investigation robots. Before and after robot use, ultrasonic sensors must be reinstalled and secured with specific tools. This operation is crucial because if the ultrasonic sensors are not properly secured when the investigation robot is not in use, they are very likely to be damaged by external factors such as collisions and vibrations. Once the sensor is damaged, it will not only directly lead to equipment failure and affect subsequent investigation work, but also incur additional costs due to sensor replacement, resulting in unnecessary economic losses. However, currently, when using geotechnical engineering investigation robots, operators need to use specific tools and follow strict procedures for installation. This installation process greatly prolongs the preparation time, significantly reduces work efficiency, and to some extent restricts the progress of geotechnical engineering investigation projects. To address this, we propose a geotechnical engineering investigation robot. Utility Model Content

[0004] The purpose of this invention is to provide a geotechnical engineering exploration robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a geotechnical engineering exploration robot, comprising a harvesting device body and a connecting disc, two slide rails fixedly connected to the top of the harvesting device body, sliders slidably connected inside the slide rails, mounting plates fixedly connected to the top of the two sliders, a fixed column fixedly connected to the top of the mounting plate, multiple mounting blocks fixedly connected to the outside of the fixed column, a rotating shaft fixedly connected inside the mounting block, a gripper rotatably connected to the outside of the rotating shaft, a connecting column rotatably connected to the top of the connecting disc, and an ultrasonic sensor fixedly connected to the top of the connecting column.

[0006] The slide rail has two fixed blocks inside and a groove inside.

[0007] The fixed column has an external threaded connection with an external ring, and the external ring has two fixed handles fixedly connected to the outside. The fixed column also has a tapered ring slidingly connected to the outside.

[0008] The connecting disc is fixedly connected to a directional rotation mechanism at its top, a ratchet is fixedly connected to the outside of the connecting column, a connecting piece is fixedly connected inside the directional rotation mechanism, a limit rod is fixedly connected to the top of the connecting piece, and a pawl is rotatably connected to the outside of the limit rod.

[0009] The directional rotation mechanism is externally fixedly connected to a jacking mechanism, which is externally fixedly connected to a sleeve. A spring is installed inside the sleeve, and a cylindrical sleeve is slidably connected inside the sleeve.

[0010] The ratchet is externally connected to the inside of the directional rotation mechanism, and the outside of the pawl is in contact with the outside of the ratchet.

[0011] The fixed column has a threaded groove on its outside, and the top of the outer ring contacts the bottom of the conical ring.

[0012] This utility model has at least the following beneficial effects:

[0013] In use, the clamping and fixing of the connecting disc's outer edge by the gripper, along with the cooperation of the ratchet and pawl in the directional rotation mechanism, ensures the stability of the ultrasonic sensor after installation. The clamping force of the gripper prevents the sensor from loosening due to vibration during operation, while the limiting effect of the ratchet and pawl ensures stable operation of the sensor in the set direction, avoiding the impact of angle changes on the detection effect and improving the reliability of the sensor. When adjusting the angle of the ultrasonic sensor, simply hold the sensor and rotate it, causing the connecting column and ratchet to rotate within the directional rotation mechanism. Each rotation of the ratchet is limited by the pawl, achieving precise angle adjustment and allowing rotation only in one direction. This enables the sensor to be accurately adjusted to the required detection angle, meeting different working needs and improving the accuracy and specificity of the detection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a geotechnical engineering exploration robot, including a harvesting device body 1 and a connecting disc 6. Two slide rails 2 are fixedly connected to the top of the harvesting device body 1. Two stops 201 are fixedly connected inside the slide rails 2. A groove 202 is formed inside the slide rails 2. A slider 3 is slidably connected inside the slide rails 2. Pushing the slider 3 to slide within the groove 202 adjusts the position of the mounting plate 301, thereby changing the horizontal position of the ultrasonic sensor 7. The mounting plate 301 is fixedly connected to the top of the two sliders 3. A fixing post 4 is fixedly connected to the top of the mounting plate 301. An external ring 401 is threadedly connected to the outside of the fixing post 4. Two fixing handles 402 are fixedly connected to the outside of the external ring 401. A conical ring 403 is slidably connected to the outside of the fixing post 4. A threaded groove is formed on the outside of the fixing post 4. The top of the external ring 401 contacts the bottom of the conical ring 403. Multiple mounting handles are fixedly connected to the outside of the fixing post 4. Block 5 is mounted on a mounting block. A rotating shaft 501 is fixedly connected inside the mounting block 5. A gripper 502 is rotatably connected to the outside of the rotating shaft 501. A connecting post 602 is rotatably connected to the top of the connecting disc 6. An ultrasonic sensor 7 is fixedly connected to the top of the connecting post 602. The operator holds and rotates the fixing handle 402, which causes the outer ring 401 to rotate outside the fixing post 4. Since the outer ring 401 and the fixing post 4 are threaded together, the outer ring 401 moves upward as it rotates, thus pushing the conical ring 403 upward. As the conical ring 403 moves upward, it pushes the bottom of the gripper 502, causing the gripper 502 to rotate around the rotating shaft 501 inside the mounting block 5. During the rotation of the gripper 502, the gripper 502 gradually approaches the outer edge of the connecting disc 6 and eventually clamps and fixes the outer edge of the connecting disc 6, thereby stably mounting the ultrasonic sensor 7 on the fixing post 4.

[0022] A directional rotation mechanism 601 is fixedly connected to the top of the connecting disc 6. A ratchet 603 is fixedly connected to the outside of the connecting column 602. A connecting piece 604 is fixedly connected inside the directional rotation mechanism 601. A limit rod 605 is fixedly connected to the top of the connecting piece 604. A pawl 606 is rotatably connected to the outside of the limit rod 605. The ratchet 603 is rotatably connected to the inside of the directional rotation mechanism 601. The outside of the pawl 606 is in contact with the outside of the ratchet 603. Each time the ratchet 603 rotates, it pushes the pawl 606, causing the pawl 606 to rotate around the limit rod 605 and engage in one of the grooves of the ratchet 603, thus limiting the ratchet 603 to rotate only in this one direction. The operator can precisely adjust the detection angle of the ultrasonic sensor 7, and the adjusted angle can be stably maintained.

[0023] The directional rotation mechanism 601 is externally fixedly connected to a jacking mechanism 8, and the jacking mechanism 8 is externally fixedly connected to a sleeve 801. A spring 802 is installed inside the sleeve 801, and a cylindrical sleeve 803 is slidably connected inside the sleeve 801. The jacking and resetting method makes the engagement between the pawl 606 and the ratchet 603 more tight, further improving the stability and accuracy of the angle adjustment of the ultrasonic sensor 7, ensuring that the angle of the ultrasonic sensor 7 will not easily change during use, and guaranteeing the accuracy of geotechnical engineering investigation work.

[0024] The working principle of this utility model is as follows: A slide rail 2 is installed on the top of the main body 1 of the picking device, and a stop block 201 is installed at both ends of the slide groove 202 to limit the movement range of the slider 3 in the slide groove 202. The slider 3 can slide freely in the slide groove 202. An mounting plate 301 is connected to the slider 3 to provide an installation plane for the subsequent installation of the ultrasonic sensor 7. The mounting plate 301 is connected to the fixing column 4, and the outer ring 401 can be fixed to the fixing column 4 by bolt connection.

[0025] Then, when installing the ultrasonic sensor 7, the ultrasonic sensor 7 is fitted with the connecting disc 6, so that the bottom of the connecting disc 6 contacts the top of the fixing post 4. Then, the fixing handle 402 is held and rotated, so that the fixing handle 402 rotates outside the fixing post 4, pushing the conical ring 403 upward, so that the conical ring 403 pushes the bottom of the clamp 502, so that the clamp 502 rotates inside the mounting block 5, and at the same time, the clamp 502 clamps and fixes the outer edge of the connecting disc 6. Then, when adjusting the angle of the ultrasonic sensor 7, simply hold the ultrasonic sensor 7 and rotate it, so that the ultrasonic sensor 7 drives the connecting post 602 and the ratchet 603 to rotate and connect inside the directional rotation mechanism 601. Then, each rotation of the ratchet 603 will push the pawl 606, so that the pawl 606 is engaged in one of the grooves of the ratchet 603, limiting the ratchet 603 to rotate only in this direction.

[0026] Example 2

[0027] Please see Figures 3 to 4 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that after the ratchet 603 pushes the pawl 606, the sleeve 801 on the pushing mechanism 8 outside the directional rotation mechanism 601, together with the spring 802 and the cylindrical sleeve 803, pushes the pawl 606 to reset, making the engagement between the pawl 606 and the ratchet 603 more tight.
