Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and more specifically, to a geotechnical engineering drilling device. Background Technology

[0002] Geotechnical engineering is a branch of civil engineering that studies the mechanical properties and engineering behavior of rocks and soils, and uses this knowledge to solve engineering problems related to foundations, underground spaces, and slopes in construction projects. In short, it deals with all engineering work involving soil and rock. The core task of geotechnical drilling equipment is to drill holes from the surface into the ground to obtain soil and rock samples, conduct in-situ tests, and explore geological structures and groundwater conditions.

[0003] For existing geotechnical drilling equipment, if a spray dust suppression system can be implemented during use, the cleanliness of the surrounding working environment can be greatly improved, preventing workers from inhaling dust for extended periods and thus ensuring their physical and mental health. A spray dust suppression system can be installed to spray water mist during drilling to reduce the dust concentration in the surrounding air. Therefore, improving the existing technology is one of the necessary technical means.

[0004] In view of this, we have studied and improved the existing problems to provide a geotechnical engineering drilling device, aiming to solve the problems and improve its practical value through this technology. Utility Model Content

[0008] As a further optimization of this technical solution, the water tank of this utility model has a drain pipe connected to the lower side of one side, a water inlet hopper connected to the top side of one side, support legs fixedly connected to both sides of the bottom of the base plate, and a controller electrically connected to the water pump and the second servo motor fixedly connected to the top of the base plate.

[0027] Please see Figures 1 to 5 This utility model provides a specific technical implementation scheme for a geotechnical engineering drilling device:

[0028] A geotechnical drilling device includes: a base plate 1, a support 2, a first screw 3, a locking block 4, a first servo motor 5, a crossbeam 6, a second servo motor 7, a drill rod 8, a reinforcing frame 9, a support leg 10, a water tank 11, a second screw 12, a limiting block 13, a water pump 14, a first guide pipe 15, a second guide pipe 16, an atomizing nozzle 17, a slide rail 18, a ball bearing 19, a controller 20, a drain pipe 21, and a water inlet hopper 22. A water tank 11 is fixedly connected to the top of the base plate 1, and a water pump 14 is fixedly connected to the bottom of the inner wall of the water tank 11. The output end of the water pump 14 is connected to the first guide pipe 15, and the top two sides of the first guide pipe 15 are connected to second guide pipes. 16. The outer walls of the two second conduits 16 penetrate the inner wall of the water tank 11. The inner walls of the two second conduits 16 are connected to multiple atomizing nozzles 17. A drill rod 8 is installed above the base plate 1. A second servo motor 7 is fixedly connected to the top of the drill rod 8. The models of the water pump 14 and the second servo motor 7 are not limited, as long as they meet the usage requirements. The water pump 14 can draw water from the inside of the water tank 11, and then transport it through the first conduit 15 and the second conduit 16. Finally, it is atomized and sprayed out through the atomizing nozzles 17, thereby realizing the function of spray dust suppression. The second servo motor 7 can drive the drill rod 8 to rotate so that drilling work can be carried out through the drill rod 8.

[0029] A drain pipe 21 is connected to the lower side of one side of the water tank 11, and a water inlet 22 is connected to the top side of the water tank 11. Support legs 10 are fixedly connected to both sides of the bottom of the base plate 1, and a controller 20 that is electrically connected to the water pump 14 and the second servo motor 7 is fixedly connected to the top of the base plate 1. The model of the controller 20 is not limited, as long as it meets the usage requirements. The staff can use the controller 20 to control the various electrical devices in this case for coordinated operation.

[0030] A bracket 2 is fixedly connected to both sides of the top of the base plate 1. A first servo motor 5 is fixedly connected to the top of each bracket 2, and both first servo motors 5 are electrically connected to the controller 20. A first screw 3 is rotatably connected to the inner wall of each bracket 2 through a sealed bearing. The two first screws 3 are rotatably connected to the inner wall of each bracket 2 through sealed bearings. A locking block 4 is threadedly connected to the outer wall of each first screw 3, and the outer wall of each locking block 4 is slidably engaged with the inner wall of each bracket 2. A crossbeam 6 is fixedly connected to the outer wall of each locking block 4, and the top of the crossbeam 6 is fixedly connected to the outer wall of a second servo motor 7. The output end of the second servo motor 7 is rotatably connected to the inner wall of the crossbeam 6 through a sealed bearing. The model of the first servo motor 5 is not limited, as long as it meets the usage requirements. The first servo motor 5 can drive the first screw 3 to rotate, thereby changing the position of the locking block 4 through the first screw 3, so as to adjust the position height of the crossbeam 6 through the locking block 4, and thus change the position height of the drill rod 8.

[0031] Two reinforcing frames 9 are fixedly connected to the outer walls of both brackets 2, and the bottoms of the multiple reinforcing frames 9 are fixedly connected to the top of the base plate 1; the reinforcing frames 9 can improve the strength of the brackets 2.

[0032] Two slide rails 18 are fixedly connected to the top of the base plate 1. The outer walls of both slide rails 18 are slidably engaged with limit blocks 13. Multiple balls 19 are rotatably connected to the inner walls of both limit blocks 13. The outer walls of the balls 19 are in contact with the outer wall of the drill rod 8. Second screws 12 are rotatably connected to the inner walls of both limit blocks 13 via sealed bearings, and the outer walls of the two second screws 12 are threadedly connected to the inner walls of the two brackets 2 respectively. The slide rails 18 can limit the position of the limit blocks 13. The design of the balls 19 ensures that the movement of the drill rod 8 is not affected. In the event of dynamic interference, to ensure that the limit block 13 can limit the drill rod 8, a locking structure for the second screw 12 needs to be set to ensure the stability of the limit block 13 during use. The specific locking structure can be achieved by using a double nut locking method, that is, a locking nut is set on both sides of the connection between the second screw 12 and the bracket 2, and the second screw 12 is firmly locked to the inner wall of the bracket 2 by the two locking nuts. Of course, other self-locking methods can also be used. The specific self-locking method is not limited and can be selected according to the actual use.

[0033] Specifically, it is important to note that a synchronizer should be installed between the two first servo motors 5 to ensure synchronized movement. Each motor is equipped with a high-precision encoder, capable of real-time monitoring of its operating status (such as current speed and actual position) and feeding this data back to the synchronizer. When a difference is detected between the two motors, the synchronizer will fine-tune the control signal of one or both motors according to a preset synchronization algorithm (such as proportional-integral-derivative control, i.e., PID algorithm). For example, if motor B is slightly slower, the synchronizer will send an "acceleration" signal to the driver of motor B and may also fine-tune the speed of motor A to quickly bring the two motors into sync. Furthermore, during operation, personnel should take appropriate protective measures for all electrical equipment in this case. To avoid damage during prolonged use due to the complex operating conditions, specific protective measures are not limited and can be selected according to the actual usage situation, based on meeting the technical characteristics of this case. During use, since the first screw 3 and the second screw 12 are exposed, staff need to clean and maintain them regularly to avoid long-term exposure and dust accumulation. The specific cleaning and maintenance cycle is not limited and can be selected according to the actual usage situation. During use, since the position of the second servo motor 7 is not fixed, a certain amount of wire slack needs to be reserved during installation to avoid wire pulling during movement. The specific length of the reserved slack is not limited and can be selected according to the actual usage situation.

[0034] Specific implementation steps:

[0035] When in use, the operator first twists the second screw 12, which changes the position of the limit block 13 on the outer wall of the slide rail 18. When the ball bearing 19 is in contact with the outer wall of the drill rod 8, the twisting of the second screw 12 can be stopped, and drilling can then begin. At the same time, the first servo motor 5 and the second servo motor 7 are turned on. The second servo motor 7 drives the drill rod 8 to rotate, and the first servo motor 5 drives the first screw 3 to rotate. Then, the position and height of the drill rod 8 are changed by the clamping block 4 and the crossbeam 6 to carry out drilling work. At the same time, the water pump 14 is turned on, which draws water from the water tank 11 into the first conduit 15 and the second conduit 16. Finally, the water is atomized and sprayed out through the atomizing nozzle 17 to achieve dust suppression.

[0036] In summary, this geotechnical engineering drilling device, through the arrangement of a base plate, water tank, water pump, first conduit, second conduit, and atomizing nozzle, can spray water mist during operation, thereby reducing the dust concentration in the surrounding working environment. This prevents workers from inhaling large amounts of dust, ensuring their safety and improving their comfort. The limiting block, slide rail, ball bearings, and second screw provide auxiliary restraint on the drill rod during use. Furthermore, the ball bearings' contact with the drill rod surface prevent interference with its movement, effectively ensuring the drill rod's operational safety and preventing positional deviation. The limiting block, slide rail, ball bearings, and second screw of this invention provide auxiliary restraint on the drill rod during use, and the ball bearings' contact with the drill rod surface prevent interference with its movement, effectively ensuring the drill rod's operational safety and preventing positional deviation.
