Description

Technical Field

[0001] This utility model belongs to the field of engineering survey technology, and specifically relates to a hydraulic engineering survey drilling rig. Background Technology

[0002] With the continuous development of new energy mountain wind power projects, geological surveys of project sites are necessary. According to industry standards such as the "Code for Geological Investigation of Onshore Wind Farms" (NB / T31030-2022), the foundation types for buildings are typically natural foundations or pile foundations, depending on the bearing capacity of the foundation strata at different foundation levels. Different foundation types require different drilling depths. Statistics show that in Northwest China, the required drilling depth for loess overburden strata is generally 40-50m (undisturbed sample diameter ≥75mm); while the exploration depth for bedrock strata is controlled at 25-35m (rock sample diameter ≥65mm).

[0003] Geological exploration of the base involves drilling and in-situ testing using drilling rigs. While mainstream traditional drilling rigs (such as the XY-100 and XY-1A small vertical shaft drilling rigs) can meet basic exploration requirements, they have significant limitations in terms of weight, mobility, and functionality. In geological exploration for new energy projects in complex terrain, these rigs are often bulky, cumbersome to assemble and disassemble, and face transportation difficulties in complex conditions such as mountains, deserts, and forests, making it impossible to quickly reach the project site for operations. Mainstream traditional drilling rigs conduct in-situ tests after drilling operations. The in-situ test process is as follows: Authorization announcement number CN106050125B, name: a portable fully hydraulic engineering exploration drilling rig. During the in-situ test, the standard penetration test (SPT) assembly will be worn due to impact with the soil layer, or soil will stick to the SPT assembly. The main body weight of the SPT assembly is normally 63.5kg + / -0.5kg. If the main body weight is less than 63kg or greater than 64kg, the SPT assembly will change the hammering energy to the soil layer, resulting in inaccurate in-situ test data. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic engineering exploration drilling rig that facilitates the transportation and transfer of various modules of the exploration drilling rig, and allows for real-time monitoring of the status of standard penetration test components during in-situ experiments, thereby improving the accuracy of in-situ experimental data.

[0005] The purpose of this utility model is achieved through the following technical solution: a hydraulic engineering exploration drilling rig is provided, including a power module, a drilling tower module, an intelligent control module, a standard penetration test (SPT) component, a pulley assembly, and a weighing sensor. The power module is connected to the drilling tower module, the pulley assembly is installed on the top of the drilling tower module, the SPT component is suspended from the drilling tower module by the pulley assembly, and the weighing sensor is installed in the SPT component to monitor its weight. The power module and the weighing sensor are electrically connected to the intelligent control module. The power module, intelligent control module, and SPT component are all detachably mounted from the drilling tower module. The power module drives the drilling tower module to move up and down.

[0006] Preferably, the pulley assembly includes a pulley seat, a pulley, a support shaft, and a bearing. The pulley seat is installed on the top of the drilling rig module, the support shaft is located inside the pulley seat, the bearing is located on the outside of the support shaft, and the pulley is installed on the outside of the bearing.

[0007] Preferably, it further includes a first displacement sensor, which is disposed on the pulley assembly.

[0008] Preferably, the intelligent control module includes a control cabinet and a control panel, with the control panel connected to the standard penetration test assembly via a solenoid valve.

[0009] Preferably, the power module includes a gasoline engine, a hydraulic pump, a hydraulic motor, and a hydraulic oil tank. The gasoline engine is connected to the hydraulic pump, the hydraulic pump is connected to the hydraulic oil tank through a hydraulic pipeline, and the hydraulic pump is connected to the hydraulic motor through a hydraulic pipeline.

[0010] Preferably, the power module further includes an integrated battery, which is connected to the gasoline engine.

[0011] Preferably, the outer surface of the hydraulic oil tank is provided with a finned structure.

[0012] Preferably, it also includes a second displacement sensor, which is disposed at the bottom of the drilling rig module.

[0013] Due to the adoption of the above technical solution, this utility model has the following advantages:

[0014] The power module is detachably connected to the drilling rig module via hydraulic lines. The intelligent control module connects to each module via electrical wires or wirelessly. Therefore, the power module, intelligent control module, standard penetration test (SPT) assembly, and drilling rig module constitute independent modules, meaning they are designed separately. Each module can be rapidly deployed via drone lifting or manual transport, making it particularly suitable for exploration operations in complex terrains such as steep mountains, loose deserts, and densely vegetated forests. During in-situ testing, a weighing sensor monitors the weight of the SPT assembly in real time to ensure sufficient impact energy on the soil. The intelligent control module corrects experimental parameters based on the weight of the SPT assembly, thereby improving the accuracy of in-situ experimental data. Attached Figure Description

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] Please see Figures 1 to 3 A hydraulic engineering exploration drilling rig includes a power module 1, a drilling tower module 2, an intelligent control module 3, a standard penetration test (SPT) assembly 4, a pulley assembly 5, and a weighing sensor 6. The power module 1 is connected to the drilling tower module 2. The pulley assembly 5 is installed on the top of the drilling tower module 2. The SPT assembly 4 is suspended from the drilling tower module 2 via the pulley assembly 5. The weighing sensor 6 is installed in the SPT assembly 4 to monitor its weight. The power module 1 and the weighing sensor 6 are electrically connected to the intelligent control module 3. The power module 1, intelligent control module 3, and SPT assembly 4 are all detachably mounted to the drilling tower module 2. The power module 1 drives the drilling tower module 2 to move up and down. Specifically, the drilling tower module 2 includes a base frame 21 and a drilling tower body 22. The drilling tower body 22 includes a fixed square tube 221 and a telescopic square tube 222. The fixed square tube 221 is vertically mounted on the base frame 21. The power module 1 drives the telescopic square tube 222 to move axially along the fixed square tube 221. The standard penetration test assembly 4 adopts existing technology and mainly includes a standard penetration hammer 41, a wire rope 42, and a hydraulic winch 43. One end of the wire rope 42 is connected to the hydraulic winch 43, and the other end is connected to the standard penetration hammer 41 through a pulley assembly 5. A load cell 6 is installed at the end of the wire rope 42 near the standard penetration hammer 41 to monitor the weight of the standard penetration test assembly 4 in real time. The power module 1 is detachably connected to the drilling tower module 2 via hydraulic lines. The intelligent control module 3 is connected to each module via wires or wirelessly. Preferably, the load cell 6 is a wireless load cell, model WX1-BHSUK-A, or a wired load cell, with one end of the cable connected to the load cell and the other end connected to the intelligent control module 3.

[0029] This invention discloses a hydraulic engineering exploration drilling rig in which the power module 1, intelligent control module 3, and standard penetration test (SPT) component 4 are all detachably mounted from the drilling tower module 2, meaning they are designed to be separate from each other. The maximum weight of a single module does not exceed 100 kg. Each module can be quickly deployed via drone hoisting or manual transport, making it particularly suitable for exploration operations in complex terrains such as steep mountains, loose deserts, and densely vegetated forests. In use, the modules are first assembled, and the intelligent control module 3 is activated to check the working status of each module. Then, the power module 1 is activated, driving the drilling tower module 2 to rise and fall, thereby driving the drill rod to perform drilling operations or to drive the SPT component 4 to conduct in-situ tests. During the in-situ test, the weighing sensor 6 monitors the weight of the SPT component 4 in real time to ensure the SPT component 4 delivers sufficient impact energy to the soil. The intelligent control module 3 corrects the experimental parameters based on the weight of the SPT component 4, thereby improving the accuracy of the in-situ experimental data.

[0030] Further, please refer to Figure 1 , Figure 2 and Figure 4 The pulley assembly 5 includes a pulley seat 51, a pulley 52, a support shaft 53, and a bearing 54. The pulley seat 51 is installed at the top of the drilling tower module 2, the support shaft 53 is located inside the pulley seat 51, the bearing 54 is located on the outside of the support shaft 53, and the pulley 52 is installed on the outside of the bearing 54. Specifically, the two ends of the pulley seat 51 are fixed to the top of the telescopic square tube 222 by welding or bolts. The center of the pulley 52 is sleeved in the support shaft 53. The pulley assembly 5 also has pulley bearing retaining springs 55, with two pulley bearing retaining springs 55 fixed to both sides of the bearing 54, thereby fixing the pulley 52 to the support shaft 53. The pulley 52 has a groove 521 along its circumference. The shape of the groove 521 includes, but is not limited to, U-shaped, C-shaped, V-shaped, and trapezoidal shapes. The V-shaped or trapezoidal shape can accommodate steel wire ropes 42 with different outer diameters, improving application scenarios.

[0031] Further, please refer to Figure 1 It also includes a first displacement sensor 7, which is mounted on the pulley assembly 5. Specifically, the first displacement sensor 7 is mounted on the pulley seat 51 and electrically connected to the intelligent control module 3. The first displacement sensor 7 measures the displacement of the wire rope 42 as the pulley 52 rotates, and feeds the displacement signal back to the intelligent control module 3. The intelligent control module 3 receives the command and converts it into a current signal. When the displacement signal received by the intelligent control module 3 is greater than the preset maximum displacement value of the wire rope 42 (the preset maximum displacement of the wire rope is 80cm), it indicates that the standard penetration hammer 41 is not falling off or the lifting claw cannot hook the hammer head. The intelligent control module 3 automatically alarms and implements automatic emergency stop, effectively preventing abnormal situations from occurring. Preferably, the first displacement sensor 7 is a laser rangefinder.

[0032] Further, please refer to Figure 1 and Figure 3 The intelligent control module 3 includes a control cabinet 31 and a control panel 32. The control panel 32 is connected to the standard penetration test assembly 4 via a solenoid valve. Specifically, the control panel 32 is connected to the hydraulic winch 43 via a solenoid valve. A display screen 321 is located on the upper surface of the control panel 32, and a controller is located inside the control cabinet 31. The working principle of the exploration drilling rig is as follows:

[0033] The load cell 6 collects the load parameters of the wire rope 42 in real time and transmits the dynamic weight signal to the controller. After logical processing, the controller converts the received command into a current signal, drives the solenoid valve to switch, and then controls the lifting and lowering of the hydraulic winch 43 to achieve the periodic vertical movement of the standard penetration test hammer 41. The controller presets the weight detection threshold.

[0034] Unloaded weight is 5-30kg; loaded weight is 45-70kg.

[0035] Specifically, the standard penetration test hammer 41 is connected to the wire rope 42, the controller is started, and the hydraulic winch 43 drives the standard penetration test hammer 41 to rise. When it rises 76cm, the automatic trip trigger is activated, and the standard penetration test hammer 41 automatically falls and undergoes free fall, impacting the bottom hammer pad to perform one standard penetration test. At this time, the load cell 6 detects that the tension of the wire rope 42 has suddenly decreased to the unloaded weight and immediately transmits a signal to the controller. The controller issues an instruction and executes the following sequence of actions: (i) close the solenoid valve, and the hydraulic winch 43 stops working; (ii) record the current number of hammer blows; (iii) the solenoid valve is reversed, and the hydraulic winch 43 is restarted to automatically reverse and descend. The wire rope 42 is reattached to the standard penetration test hammer 41, and the load cell 6 detects again that the tension of the wire rope 42 is at the loaded weight state. After transmitting the signal to the controller, the controller reopens the solenoid valve and starts the next cycle of hammer blows. A weighing sensor 6 is installed on the exploration drilling rig. The controller can close or open the hydraulic winch 43 through the solenoid valve according to the preset weight threshold, thereby limiting the lifting stroke of the standard penetration test hammer 41. This makes the test process independent of manual visual inspection, reduces human factors, and improves the degree of automation. In addition, the weighing sensor 6 monitors the weight of the standard penetration test component 4 in real time to ensure that the hammering energy of the standard penetration test component 4 on the soil layer is sufficient. The intelligent control module 3 corrects the experimental parameters according to the main weight of the standard penetration test component 4, thereby improving the accuracy of the in-situ experimental data.

[0036] Further, please refer to Figure 1 and Figure 3The power module 1 includes a gasoline engine 11, a hydraulic pump 12, a hydraulic motor 13, and a hydraulic oil tank 14. The gasoline engine 11 is connected to the hydraulic pump 12, which is connected to the hydraulic oil tank 14 via hydraulic lines. The hydraulic pump 12 is also connected to the hydraulic motor 13 via hydraulic lines. Specifically, the power module 1 has a mounting frame 15, in which both the gasoline engine 11 and the hydraulic pump 12 are mounted. In use, the gasoline engine 11 drives the hydraulic pump 12 to deliver hydraulic oil from the hydraulic oil tank 14 to the hydraulic pump 12. The high-pressure hydraulic oil output by the hydraulic pump 12 drives the hydraulic motor 13 to rotate, thereby driving the telescopic square tube 222 to move axially along the fixed square tube 221. Preferably, there are two sets of gasoline engines 11 and hydraulic pumps 12, located in different mounting frames 15. When drilling in bedrock boreholes, if the geological requirements dictate a borehole diameter greater than Φ130mm and a drilling depth greater than 40m, the two sets of gasoline engines 11 and hydraulic pumps 12 are connected in parallel to increase power and enhance drilling capability. When drilling into a borehole with a diameter of Φ94mm-Φ110mm and a depth of less than 50m, a gasoline engine 11 and a hydraulic pump 12 are used. Preferably, a speed sensor is installed at the output shaft of the hydraulic motor 13. The intelligent control module 3 collects data from the speed sensor in real time and displays the real-time speed parameters on the display screen 321, which is convenient for the driller to read and control.

[0037] Further, please refer to Figure 1 and Figure 3 The power module 1 also includes an integrated battery 111, which is connected to the gasoline engine 11. Specifically, the integrated battery 111 is detachably mounted in the mounting frame 15 using screws. The integrated battery 111 drives the gasoline engine 11 to rotate, thereby driving the hydraulic pump 12. The detachable design of the integrated battery 111 further reduces the weight of the power module 1, and the mounting frame 15 further facilitates carrying and transporting the power module 1.

[0038] Furthermore, the outer surface of the hydraulic oil tank 14 is provided with a finned structure. Specifically, the outer surface of the hydraulic oil tank 14 is provided with a finned structure, and a temperature sensor is installed inside the hydraulic oil tank 14. The temperature sensor is electrically connected to the intelligent control module 3 to monitor the temperature of the hydraulic oil. The use of a finned heat dissipation structure increases the heat dissipation area, ensures heat dissipation effect, reduces the need for additional heat dissipation devices, helps to reduce the weight of the hydraulic oil tank 14, and is more suitable for mountainous areas with complex terrain.

[0039] Further, please refer to Figure 2 It also includes a second displacement sensor 8, which is located at the bottom of the drilling tower module 2. When the exploration drilling rig performs drilling operations, the intelligent control module 3 obtains the borehole entry data in real time and simultaneously displays real-time parameters such as drilling depth on the display screen 321 of the control panel 32, which is convenient for the driller to read and control. Preferably, the second displacement sensor 8 is a laser rangefinder.

[0040] This utility model discloses a hydraulic engineering exploration drilling rig. The hydraulic oil tank 14, gasoline engine 11, hydraulic pump 12, control cabinet 31, control panel 32, standard penetration test (SPT) assembly 4, and drilling tower module 2 constitute independent modules, meaning they are designed separately. The maximum weight of a single module does not exceed 100 kg. Each module can be quickly deployed via drone hoisting or manual transport, making it particularly suitable for exploration operations in complex terrains such as steep mountains, loose deserts, and densely vegetated forests. During in-situ testing, the weighing sensor 6 monitors the weight of the SPT assembly 4 in real time to ensure sufficient impact energy on the soil. The intelligent control module 3 corrects experimental parameters based on the weight of the SPT assembly 4, thereby improving the accuracy of in-situ experimental data. The first displacement sensor 7 monitors the rising state of the SPT assembly 4, effectively preventing abnormal situations. The power module is equipped with a display screen 321, a second displacement sensor 8, and a speed sensor at the output shaft of the hydraulic motor 13. The intelligent control module 3 collects real-time data from the speed sensor and displacement, and simultaneously displays real-time parameters such as rotational speed and drilling depth on the display screen 321 for easy reading and control by the driller. A finned structure is provided on the surface of the hydraulic oil tank 14 to reduce its weight while ensuring effective heat dissipation.

It should be understood that the above description is only a specific implementation method of this utility model and is not intended to limit this utility model.
