DETAILED DESCRIPTION

[0020] The utility model will be further explained in connection with the drawings and examples.

[0021] Among the existing discovered implementable technologies, the drilling device is a device for drilling holes in the ground, rock or other solid materials. It drives the drill rod and drill bit to rotate through a power device and applies axial pressure, so that the drill bit cuts into the material to form a hole. The drilling device is widely used in geological exploration, oil exploitation, building foundation construction, mine exploitation and many other fields.

[0022] Main components

[0023] Power system

[0024] Type: Common power sources include electric motors and hydraulic motors. Electric motors use electrical energy to convert into mechanical energy, which has the advantages of easy control of speed and torque, and convenient power supply. Hydraulic motors are driven by the pressure energy of hydraulic oil, which has the characteristics of large torque and stable work in harsh environments.

[0025] Application scenario example: In small drilling devices for geological exploration, since the working environment is relatively good and the equipment mobility is required, electric motors are often used as power systems; while in large mine exploitation drilling equipment, hydraulic motors are more commonly used because high torque is needed to deal with hard rock.

[0026] Drill rod

[0027] Structure and material: The drill rod is usually a hollow long rod, and its material is generally high-strength alloy steel. This material has high strength and toughness, and can withstand the torque and axial force during drilling. The two ends of the drill rod have connecting structures for connecting with other drill rods or drill bits, power devices.

[0028] Function and Role: Its main role is to transmit power and axial pressure, making the drill bit rotate and drill down. At the same time, the hollow structure can be used to discharge the cuttings generated during drilling or inject cooling liquid, etc. For example, in oil drilling, the drill pipe can deliver drilling fluid to the drill bit, playing a role in cooling the drill bit and carrying cuttings back to the ground.

[0029] Drill Bit

[0030] Classification and Characteristics: There are many types of drill bits, which can be divided into various types according to the drilling object. The twist drill bit is the most common one, which is suitable for soft rock and soil, and its spiral blade can effectively discharge cuttings. Diamond drill bits are mainly used for hard rock, and their cutting edges are embedded with diamond particles, which have extremely high hardness and can efficiently break rock.

[0031] Working Principle: The drill bit rotates under the power of the drive, and its cutting edge contacts the material being drilled, breaking the material through cutting, grinding, or impact. For example, when using an impact drill bit, the drill bit will produce axial impact force while rotating, which is very effective for breaking hard rock.

[0032] Feed Mechanism

[0033] Working Mode: The feed mechanism is used to control the axial feed speed of the drill pipe and drill bit, which can be manual, such as through a hand crank to control the screw feed device, or automatic, using a motor to drive a ball screw to achieve precise feed control.

[0034] Importance: Proper feed speed is crucial to drilling quality and efficiency. If the feed speed is too fast, it will cause excessive wear of the drill bit, reduce drilling accuracy, and even damage the drill bit; if the feed speed is too slow, it will affect drilling efficiency.

[0035] Cooling System

[0036] Cooling Method and Medium: During drilling, a large amount of heat is generated due to friction between the drill bit and the material, so a cooling system is needed to prevent the drill bit from overheating. The cooling method mainly includes liquid cooling and gas cooling. The commonly used medium for liquid cooling is water or special cooling liquid, which is delivered to the vicinity of the drill bit through pipes for cooling. Gas cooling generally uses compressed air, which not only cools the drill bit, but also helps to remove cuttings from the borehole.

[0037] Role and Effect: Effective cooling can prolong the service life of the drill bit and improve drilling efficiency. For example, when drilling hard rock in high temperature environments, the cooling system can control the drill bit temperature within a reasonable range, ensuring the cutting performance of the drill bit, thereby successfully completing the drilling task.

[0038] Chip Removal System

[0039] Debris removal method: The main function of the debris removal system is to remove the cuttings generated during drilling from the borehole. Common methods include using the hollow structure of the drill pipe to remove cuttings along with the cooling medium, or using a dedicated debris removal channel to remove cuttings from the borehole under the action of compressed air or flushing fluid.

[0040] Significance: Timely removal of cuttings can prevent cuttings from accumulating in the borehole, affecting the normal operation of the drill bit and the quality of the borehole. In deep drilling, good debris removal is particularly important, otherwise it may cause accidents such as sticking.

[0041] Classification of drilling devices

[0042] Classification by use

[0043] Geological drilling device: mainly used for geological exploration, obtaining underground core samples to understand stratum structure, rock properties, etc. This device usually needs to have high drilling accuracy, can adapt to different geological conditions, and the drilled borehole diameter is relatively small, generally between a few centimeters to several tens of centimeters.

[0044] Oil drilling device: used for oil and gas exploration and exploitation. Such devices are very large and complex, with drilling depths of several kilometers. It needs to be equipped with a powerful power system, efficient cooling and debris removal system, and complex wellhead equipment such as blowout preventers to ensure the safety and stability of the drilling process.

[0045] Building drilling device: applied to building foundation construction, such as bored pile construction, etc. Its characteristics are large borehole diameter, generally tens of centimeters to several meters, and drilling depth is determined according to the requirements of building foundation, mainly used for underground foundation pile construction or foundation treatment.

[0046] Mine drilling device: used for detecting ore vein direction and mining ore during mining. It needs to be able to adapt to the complex terrain and hard ore of the mine, usually has high mobility and strong power, and the borehole diameter and depth are determined according to the specific needs of the mine.

[0047] Classification by drilling method

[0048] Rotary drilling device: this is the most common drilling method, which drives the drill pipe and drill bit to rotate through a power device, and uses the cutting edge of the drill bit to break the material for drilling. Rotary drilling devices are suitable for various hardness of rock and soil layers, and can achieve efficient drilling operation according to the adjustment of drill bit and drilling parameters.

[0049] Impact drilling rig: This type of rig produces axial impact force while the drill bit is rotating, mainly used for breaking hard rock. The impact force of impact drilling rig can be generated by mechanical, hydraulic or pneumatic means, and it is widely used in mining and some hard strata drilling.

[0050] Vibration drilling rig: The drill bit is vibrated by a vibrator, so that the drilled material is broken or loosened under the action of vibration, and then the material is discharged by the rotation of the drill bit or other ways to form a borehole. Vibration drilling rig is suitable for some loose soil or soft rock, and its advantage is that it has less disturbance to the stratum, and the drilled hole wall is relatively smooth.

[0051] Development trend of drilling rig

[0052] Intelligentization: With the development of technology, drilling rig gradually develops towards intelligentization. Through sensor technology, various parameters in the drilling process can be monitored in real time, such as the speed of the drill bit, torque, drilling depth, stratum pressure, etc. Then use the control system to automatically adjust the drilling strategy according to these parameters, improve the drilling efficiency and quality. For example, when the sensor detects that the drill bit encounters hard stratum and the torque increases, the control system can automatically reduce the feed speed and appropriately increase the power to avoid damage to the drill bit.

[0053] Environmental protection: In the drilling process, reducing pollution to the environment is an important development trend. On the one hand, optimize the cooling system and chip removal system to reduce the pollution of cooling liquid and rock debris to soil and water; on the other hand, develop low-noise drilling rig to reduce noise pollution in the drilling process. For example, some new drilling rigs use a closed cooling and chip removal system to concentrate the cooling liquid and rock debris for processing to prevent them from leaking into the environment.

[0054] Miniaturization and portability: In some small-scale geological exploration projects or building detection fields, there is an increasing demand for small and portable drilling rigs. These devices are small in size and light in weight, easy to transport and operate, and can meet the basic drilling requirements. For example, handheld drilling rigs can be used by geologists in the field for simple stratum sampling, and their weight may be only a few kilograms, powered by batteries and easy to operate.

[0055] A detailed introduction to an angle-adjustable drilling rig is as follows:

[0056] I. Device structure

[0057] Base

[0058] It is the base part of the entire drilling device, usually made of thick and heavy metal materials (such as cast iron or high-strength alloy steel) to ensure the stability of the device. The shape of the base can be rectangular or circular, and the bottom may have non-slip pads or fixing bolt holes for firmly fixing the device to the ground or working platform.

[0059] Support column

[0060] Vertically mounted on the base, serving as a support for other components. The support column is generally hollow cylindrical structure, inside which some reinforcing ribs can be arranged to improve its bending strength. Its height is determined according to the maximum depth of drilling and the requirements of the working range, and the material can be steel, with surface rust prevention treatment such as galvanizing or painting.

[0061] Rotary platform

[0062] Fitted on the support column, it can rotate around the support column. The rotary platform is connected with the support column through high-precision bearings to reduce the friction during rotation and can withstand large axial and radial loads. The upper surface of the rotary platform is usually flat, used to install other components of the drilling equipment. Angle scales may be provided on the edge to facilitate the operator to accurately adjust the drilling angle.

[0063] Angle adjustment mechanism

[0064] Mainly includes hydraulic jack or electric push rod. If it is a hydraulic jack, it rotates the rotary platform around the support column by the pressure of hydraulic oil to adjust the angle. The electric push rod changes the angle of the rotary platform by using the power of the motor through screw transmission and other ways. The angle adjustment mechanism is also equipped with corresponding control devices, and the operator can input the desired angle value through the control panel, and the system automatically adjusts to the specified angle.

[0065] Drilling equipment main body

[0066] Including power unit (such as motor or hydraulic motor), drill pipe and drill bit. The power unit provides power for drilling, which can transmit power to the drill pipe through belt drive, gear drive or direct drive. The drill pipe is usually a hollow rod body made of high-strength alloy steel, and the length can be spliced according to the drilling requirements. The drill bit is installed at the lower end of the drill pipe, and its type is selected according to the geological conditions and purpose of drilling, such as twist drill for soft rock or soil, diamond drill for hard rock, etc.

[0067] II. Working principle

[0068] Angle adjustment process

[0069] When the drilling angle needs to be adjusted, the operator changes the angle of the rotating platform by controlling the angle adjustment mechanism. For example, if a hydraulic jack is used, starting the hydraulic pump makes hydraulic oil enter the working chamber of the jack, and the piston rod of the jack extends or retracts, pushing the rotating platform to rotate around the support column. During rotation, whether the desired angle has been reached can be determined by observing the angle scale. When the set angle is reached, the hydraulic pump is turned off, and the hydraulic jack remains in the current position, locking the angle of the rotating platform.

[0070] Drilling process

[0071] The power unit of the drilling equipment body is started, and power is transmitted to the drill rod through the transmission device, making the drill rod rotate with the drill bit. Then, the drill rod and drill bit are gradually drilled down through the feed mechanism (which can be a manual or automatic screw feed device). During drilling, depending on different geological conditions, drilling parameters such as rotation speed, feed speed, etc. may need to be adjusted. If a harder formation is encountered, the feed speed may need to be reduced, while the power unit's power may need to be appropriately increased to ensure that the drill bit can smoothly drill in.

[0072] Three, advantages

[0073] High flexibility

[0074] It can be used for drilling operations in different complex terrains such as mountains with different slopes, building walls, etc., and the drilling angle can be easily adjusted to obtain more accurate geological samples or complete the drilling task.

[0075] High precision

[0076] With the help of the angle scale and precise angle adjustment mechanism, the drilling angle can be accurately controlled within a small error range, which is beneficial for precise drilling in scientific research and engineering construction.

[0077] Wide range of applications

[0078] Whether in geological exploration, building foundation construction, or mining, this angle-adjustable drilling device can be used in various drilling environments and requirements.

[0079] Four, application scenarios

[0080] Geological exploration

[0081] When conducting geological exploration in the field, it is necessary to drill for core samples under different terrain and formation angles. This device can adjust the drilling angle according to the slope of the mountain, the inclination angle of the formation, etc., to more effectively obtain representative samples and provide accurate data for geological research.

[0082] Construction engineering

[0083] In the construction of buildings, for example, when building on a slope or reinforcing an old building that is tilted, it is necessary to drill at an angle to install anchor rods or to reinforce the foundation. An angle-adjustable drilling device can meet this special construction requirement and ensure that the drilling angle meets the engineering design standard.

[0084] Mining

[0085] During mining, it may be necessary to drill at different angles to detect the direction and distribution of ore veins. This device can flexibly adapt to the complex terrain of the mine and the angle of the ore vein, improving the efficiency and accuracy of mineral exploration.
