Description

Technical Field

[0001] This application relates to the technical field of geological exploration equipment, and in particular to a drilling rig for geological exploration. Background Technology

[0002] In geological exploration, mineral resource exploration, and engineering geological surveys, exploration drilling rigs are essential mechanical equipment. They drive the drilling tools through a power system to drill holes below the ground, so that the borehole depth can reach the specified depth to complete geological exploration, mineral resource exploration, and other operations.

[0003] In actual geological exploration operations, due to significant differences in geological conditions, designed drilling depth, and sampling specifications at different sites, frequent disassembly and replacement of drill rods are required during drilling operations.

[0004] Meanwhile, to prevent the borehole wall from collapsing and becoming unstable, casing needs to be installed in the completed borehole section during construction. The casing provides radial support and protection for the borehole wall, ensuring that the borehole wall of the upper section remains stable during the continued drilling and sampling process. As the drilling depth increases, the casing installed in the borehole also needs to be extended section by section accordingly.

[0005] Regarding the aforementioned technologies, traditional geological exploration drilling rigs still primarily rely on manual operation for drill rod disassembly and replacement, as well as casing extension. However, due to the long length and heavy weight of the drill rods and casings, manual operation of drill rod disassembly and replacement, and casing extension is difficult and dangerous.

[0020] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0021] This application discloses a drilling rig for geological exploration.

[0022] Reference Figure 1 A geological exploration drilling rig includes a body 1, a tunneling component 2, and a placement component 3, both of which are mounted on the body 1. A controller is installed on the body 1 to control the tunneling component 2 and the placement component 3. Tracks are installed on the body 1 to allow the geological exploration drilling rig to move.

[0023] Reference Figure 1 The tunneling assembly 2 includes a tunneling section 21, a lateral movement section 22, a power head 23, and a tubular drill string 24. The tunneling section 21 is mounted on the machine body 1, and the lateral movement section 22 is mounted on the tunneling section 21. The tunneling section 21 can drive the lateral movement section 22 to move along the length direction of the tunneling section 21. The fixed end of the power head 23 is mounted on the lateral movement section 22, and the lateral movement section 22 can drive the power head 23 to move along the length direction of the lateral movement section 22. The power head 23 is electrically connected to a controller, and the working state of the power head 23 can be controlled by the controller.

[0024] Furthermore, the tunneling section 21 is a motor-screw-slide rail transmission module. The motor of the tunneling section 21 is electrically connected to the controller, which can control the tunneling section 21 to adjust the position of the lateral movement section 22 on the tunneling section 21.

[0025] Multiple tubular drill bits 24 are provided. The top of each tubular drill bit 24 is equipped with a standard connector to ensure that tubular drill bits 24 of different specifications and types can be detachably installed on the output end of the power head 23. The tubular drill bits 24 can be installed on the placement assembly 3 to achieve simultaneous storage of multiple tubular drill bits 24.

[0026] Furthermore, the tubular drill string 24 includes several drill pipes and casings, with threaded joints used between drill pipes and between casings.

[0027] The tubular drill bit 24 is placed on the machine body 1. When using a geological exploration drilling rig, the machine body 1 is first moved to the exploration site, and multiple tubular drill bits 24 are installed one by one on the placement assembly 3. Then, the controller controls the tunneling section 21 and the lateral movement section 22 so that the power head 23 is located on top of the tubular drill bit 24. The power head 23 is controlled to fix the tubular drill bit 24 to the output end of the power head 23 so that the power head 23 and the tubular drill bit 24 can work together for geological exploration. The replacement of the tubular drill bit 24 is achieved by the cooperation of the tunneling assembly 2 and the placement assembly 3. The replacement of the tubular drill bit 24 is carried out by machinery instead of manual labor, which reduces the difficulty of drill rod disassembly and replacement and casing extension operations, and improves the efficiency of drill rod disassembly and replacement and casing extension operations.

[0028] After the tubular drill string 24 is installed, geological exploration is carried out. The position of the power head 23 on the lateral section 22 is adjusted so that the position of the power head 23 is adjusted to the tunneling point. Then the power head 23 is started. The output end of the power head 23 rotates and drives the tubular drill string 24 to rotate synchronously. At the same time, the tunneling section 21 is controlled so that the lateral section 22 and the power head 23 move towards the ground to realize the geological exploration work.

[0029] Reference Figure 1 Furthermore, the lateral movement section 22 includes a lateral movement member 221 and a base plate 222. The lateral movement member 221 is mounted on the base plate 222, and the base plate 222 is mounted on the tunneling section 21. The guiding direction of the lateral movement member 221 is perpendicular to the guiding direction of the tunneling section 21. The fixed end of the power head 23 is slidably mounted on the lateral movement member 221.

[0030] In this embodiment, the transverse component 221 adopts a motor-screw-slide rail transmission module, and the motor of the transverse component 221 is electrically connected to the controller. The controller can control the transverse component 221 to adjust the position of the power head 23 on the transverse component 221.

[0031] When replacing the tubular drill string 24, the position of the power head 23 along the length of the tunneling section 21 is adjusted so that the power head 23 is positioned at the top of the tubular drill string 24 to be replaced. Then, the position of the power head 23 along the length of the lateral movement component 221 is adjusted so that the output end of the power head 23 is coaxial with the tubular drill string 24 to be replaced. The replacement of the tubular drill string 24 is achieved by controlling the power head 23. The precise control of the position of the power head 23 through the cooperation of the tunneling section 21 and the lateral movement component 221 ensures that the output end of the power head 23 can precisely align with the tubular drill string 24 to be replaced, thus improving the operational reliability of the geological exploration drilling rig during the replacement of the tubular drill string 24.

[0032] Reference Figure 1Furthermore, the tunneling unit 21 includes a frame, on which the motor-screw-slide rail transmission module of the tunneling unit 21 is mounted. The frame is hinged to the machine body 1. The tunneling assembly 2 also includes a first driving hydraulic cylinder 25. The fixed end of the first driving hydraulic cylinder 25 is hinged to the machine body 1, and the movable end of the first driving hydraulic cylinder 25 is hinged to the tunneling unit 21. The first driving hydraulic cylinder 25 is electrically connected to a controller, which allows the length of the first driving hydraulic cylinder 25 to be controlled.

[0033] By adjusting the length of the first drive hydraulic cylinder 25, the tunneling section 21 can rotate relative to the machine body 1, thereby adjusting the angle of the tunneling section 21. During geological exploration tunneling, the guiding direction of the tunneling section 21 can be adjusted to a suitable angle to meet the tunneling operations with different angle requirements; when it is necessary to move the geological exploration drilling rig, the tunneling section 21 can be adjusted to an inclined state, reducing the overall height of the geological exploration drilling rig, so that the geological exploration drilling rig can be moved flexibly.

[0034] Reference Figure 1 and Figure 2 The placement component 3 includes a first mounting plate 31 and a fixing member 32. The first mounting plate 31 is mounted on the machine body 1. Multiple mounting bases 311 are slidably mounted on the first mounting plate 31. A clearance groove is provided between the first mounting plate 31 and the machine body 1 so that the tubular drill 24 can dig downwards. The fixing member 32 is mounted on the mounting base 311.

[0035] Each mounting base 311 is provided with multiple sets of fasteners 32. The fasteners 32 have identical structures but different specifications. The largest fastener 32 is installed on the mounting base 311. The size of the fasteners 32 gradually decreases from the direction closer to the mounting base 311 to the direction farther away from the mounting base 311. Each set of fasteners 32 includes a fixed base 321 and a fixed sleeve 322. The fixed base 321 has a coaxial placement groove 3211. The fixed sleeve 322 is coaxially and fixedly installed in the placement groove 3211, and the tubular drill bit 24 can be sleeved on the fixed sleeve 322.

[0036] The largest fixed base 321 is fixedly installed on the mounting base 311. In the two adjacent sets of fixed parts 32, the fixed sleeve 322 of the larger fixed part 32 is fixedly connected to the fixed base 321 of the smaller fixed part 32.

[0037] When placing the tubular drill bit 24, the bottom of the tubular drill bit 24 is fitted onto the fixed sleeve 322. The fixed sleeve 322 provides positioning and support for the tubular drill bit 24, allowing it to be placed on the fixed base 321. This facilitates the subsequent installation of the tubular drill bit 24 onto the power head 23, thus completing the installation of the tubular drill bit 24.

[0038] By setting multiple fixed sleeves 322 of different diameters, tubular drill bits 24 of different diameters can be placed on the first mounting plate 31, improving the usability of the placement component 3, enhancing the compatibility of the geological exploration drilling rig with multiple specifications of tubular drill bits 24, and expanding the applicable range of working conditions for the geological exploration drilling rig.

[0039] Reference Figure 2 and Figure 4 The first mounting plate 31 has a mounting cavity, and a switching component 33 is mounted on the first mounting plate 31. Multiple sets of fixing components 32 are mounted on the switching component 33. The switching component 33 includes a conversion groove 331, a chain 332, a switching gear 333, and a switching motor 334.

[0040] A conversion slot 331 is formed on the first mounting plate 31. The guide direction of the conversion slot 331 is connected end to end. The conversion slot 331 communicates with the mounting cavity. The mounting base 311 is slidably mounted on the conversion slot 331. The chain 332 is disposed in the conversion slot 331. Multiple mounting bases 311 are evenly fixedly mounted on the chain 332. Multiple switching gears 333 are disposed and rotatably mounted in the mounting cavity. The switching gears 333 are meshed with the chain 332. The fixed end of the switching motor 334 is fixedly mounted on the first mounting plate 31. The output end of the switching motor 334 is coaxial with and fixedly connected to one of the switching gears 333. The switching motor 334 is electrically connected to the controller, which can control the start and stop of the switching motor 334.

[0041] The tubular drill bit 24 is placed on the first mounting plate 31 by the fixing member 32. When the tubular drill bit 24 needs to be replaced, the switching motor 334 is controlled by the controller to work. The output end of the switching motor 334 rotates and drives the switching gear 333 to rotate coaxially. The rotation of the switching gear 333 drives the chain 332 to move in the conversion groove 331. The movement of the chain 332 drives the mounting base 311 to slide along the conversion groove 331, and then drives the tubular drill bit 24 to slide on the first mounting plate 31 until the tubular drill bit 24 to be replaced moves to be coaxial with the output end of the power head 23. Then the switching motor 334 is controlled to stop working, waiting for the power head 23 to connect with the tubular drill bit 24 to be replaced. Multiple tubular drill bits 24 are integrated and placed on the first mounting plate 31, and the switching member 33 realizes the switching and installation operation of different tubular drill bits 24, which facilitates the installation of the power head 23 and the tubular drill bit 24.

[0042] When the tubular drill bit 24 is fitted onto the fixed sleeve 322, there is a gap between the tubular drill bit 24 and the fixed sleeve 322. When the fixing part 32 moves, the tubular drill bit 24 will shake.

[0043] Reference Figure 2 and Figure 3Furthermore, each set of fixing components 32 also includes a guide plate 323, a sliding block 324, and an abutment rod 325. Multiple guide plates 323 are provided, evenly distributed circumferentially in pairs and fixedly installed on the side wall of the placement groove 3211. Guide grooves 3231 are formed on the guide plates 323. The sliding block 324 is slidably installed within the guide grooves 3231, and the abutment rod 325 is fixedly installed on the sliding block 324. Under the guidance of the guide grooves 3231, the sliding block 324 can gradually approach the tubular drill bit 24 in the horizontal direction and eventually maintain a constant horizontal distance from the tubular drill bit 24.

[0044] Specifically, the guide groove 3231 is composed of a first guide section and a second guide section connected together. The guiding directions of the first guide section and the second guide section are both straight lines, and the guiding direction of the first guide section is inclined to the axis of the placement groove 3211. As the sliding block 324 slides from the end of the first guide section away from the mounting base 311 to the end closer to the mounting base 311, the sliding block 324 gradually approaches the tubular drill bit 24.

[0045] The guiding direction of the second guide section of the guide groove 3231 is parallel to the axial direction of the placement groove 3211. During the process of the sliding block 324 sliding from the first guide section into the second guide section and sliding within the second guide section, the distance between the sliding block 324 and the tubular drill bit 24 remains unchanged, and the abutment rod 325 can abut against the outer wall of the tubular drill bit 24 and form a radial limit.

[0046] When the tubular drill bit 24 is fitted onto the fixed sleeve 322, the position of the sliding block 324 on the guide groove 3231 is adjusted so that the sliding block 324 slides from the first guide section of the guide groove 3231 into the second guide section, thereby enabling the abutment rod 325 to abut against the outer wall of the tubular drill bit 24 and form a radial limit on the tubular drill bit 24, improving the stability of the tubular drill bit 24 on the fixing member 32, and thus improving the stability of the tubular drill bit 24 on the geological exploration drilling rig.

[0047] Reference Figure 2 and Figure 3 Furthermore, each set of fixing components 32 also includes an abutment plate 326, a fixing rod 327, and a return spring 328. The abutment plate 326 is slidably installed in the placement groove 3211 and can abut against the tubular drill bit 24. One end of the fixing rod 327 is fixedly installed on the abutment plate 326, and the other end of the fixing rod 327 is sleeved on the abutment rod 325.

[0048] The reset spring 328 is disposed in the placement groove 3211. One end of the reset spring 328 is fixedly connected to the abutment plate 326, and the other end of the reset spring 328 is fixedly connected to the bottom wall of the placement groove 3211. The reset spring 328 always applies a force to the abutment plate 326 in a direction away from the bottom wall of the placement groove 3211.

[0049] When the tubular drill bit 24 is fitted onto the fixed sleeve 322, the bottom of the tubular drill bit 24 contacts the abutment plate 326. Under the action of gravity, the bottom of the tubular drill bit 24 moves towards the bottom of the placement groove 3211, thereby driving the abutment plate 326 to move synchronously. While the abutment plate 326 moves, it drives the abutment rod 325 and the sliding block 324 to move towards the bottom of the placement groove 3211 through the fixed rod 327. During the process of the sliding block 324 moving towards the bottom of the placement groove 3211, under the guidance of the guide groove 3231, the abutment rod 325 moves towards the fixed sleeve 322 until the sliding block 324 slides into the second guide section of the guide groove 3231. The abutment rod 325 abuts against the outer wall of the tubular drill bit 24, so that the tubular drill bit 24 is stably fitted onto the fixed sleeve 322.

[0050] After the abutting rod 325 is pressed against the outer wall of the tubular drill bit 24, under the action of gravity, the tubular drill bit 24 continues to drive the sliding block 324, the abutting rod 325 and the fixing rod 327 to move towards the bottom of the placement groove 3211 in a synchronous manner through the abutting plate 326 until the return spring 328 is compressed to the limit state and the abutting plate 326 stops sliding.

[0051] As the tubular drill bit 24 moves the abutment plate 326 toward the bottom of the placement groove 3211, the length of the return spring 328 is compressed. Therefore, after the tubular drill bit 24 is removed from the abutment plate 326, the return spring 328 returns to its original length. Under the action of the return spring 328, the abutment plate 326 moves away from the bottom of the placement groove 3211. At the same time as the abutment plate 326 moves, it drives the sliding block 324 and the abutment rod 325 to move synchronously through the fixed rod 327. Under the action of the return spring 328, the sliding block 324 and the abutment rod 325 are reset so that they can be used again later.

[0052] Reference Figure 1 The placement assembly 3 also includes a connecting hydraulic cylinder 34 and a second mounting plate 35. The fixed end of the connecting hydraulic cylinder 34 is fixedly mounted on the first mounting plate 31. The connecting hydraulic cylinder 34 is electrically connected to a controller, which can control the length of the connecting hydraulic cylinder 34. The second mounting plate 35 is fixedly mounted on the movable end of the connecting hydraulic cylinder 34. To ensure the connection stability between the first mounting plate 31 and the second mounting plate 35, multiple connecting hydraulic cylinders 34 can be provided, and the multiple connecting hydraulic cylinders 34 are evenly installed between the first mounting plate 31 and the second mounting plate 35. The second mounting plate 35 can abut against the tubular drill bit 24. The second mounting plate 35 has a rod-taking groove 351. Under the action of the switching component 33, the tubular drill bit 24 can be moved directly below the rod-taking groove 351 to connect the power head 23 and the tubular drill bit 24.

[0053] Before placing the tubular drill bit 24, the length of the connecting hydraulic cylinder 34 is extended by the controller so that the first mounting plate 31 and the second mounting plate 35 are far apart, so that the tubular drill bit 24 can be placed on the fixing member 32.

[0054] After all the tubular drill bits 24 are placed on the fixing member 32, the length of the connecting hydraulic cylinder 34 is shortened by the controller, so that the first mounting plate 31 and the second mounting plate 35 move closer to each other. The second mounting plate 35 abuts against the top of the tubular drill bit 24. The fixing member 32 and the second mounting plate 35 clamp the tubular drill bit 24, so that the tubular drill bit 24 can be installed more stably on the placement assembly 3, further improving the installation stability of the tubular drill bit 24.

[0055] Reference Figure 1 and Figure 5 Furthermore, several clamping end caps 36 are evenly and fixedly installed on the second mounting plate 35. The number of clamping end caps 36 is the same as the number of mounting bases 311. The top of the tubular drill bit 24 can pass through the clamping end cap 36. A clamping plate 38 is slidably installed inside the clamping end cap 36. The clamping plate 38 can abut against the top of the tubular drill bit 24. A clamping spring 39 is provided inside the clamping end cap 36. One end of the clamping spring 39 is fixedly connected to the clamping end cap 36, and the other end of the clamping spring 39 is fixedly connected to the clamping plate 38. The clamping spring 39 always applies a force to the clamping plate 38 in a direction away from the second mounting plate 35.

[0056] After all the tubular drill bits 24 are placed on the fixing member 32, the switching member 33 is controlled by the controller to ensure that each tubular drill bit 24 and the clamping end cap 36 are coaxially aligned. Then, the length of the connecting hydraulic cylinder 34 is shortened so that the top of the tubular drill bit 24 passes through the clamping end cap 36 and abuts against the clamping plate 38, compressing the clamping spring 39. Under the combined action of the clamping spring 39, the clamping plate 38, and the fixing member 32, all the tubular drill bits 24 are stably subjected to the clamping force from the clamping spring 39 and the fixing member 32, while avoiding excessive shortening of the connecting hydraulic cylinder 34, which could damage the fixing member 32 and the tubular drill bit 24.

[0057] Reference Figure 1 Furthermore, the first mounting plate 31 is hinged to the machine body 1. The placement assembly 3 also includes a second driving hydraulic cylinder 37. The fixed end of the second driving hydraulic cylinder 37 is hinged to the machine body 1, and the movable end of the second driving hydraulic cylinder 37 is hinged to the first mounting plate 31. The second driving hydraulic cylinder 37 is electrically connected to the controller, and the length of the second driving hydraulic cylinder 37 can be controlled by the controller.

[0058] The length of the second drive hydraulic cylinder 37 is controlled by the controller, allowing the first mounting plate 31 to rotate relative to the machine body 1, thereby adjusting the angle of the first mounting plate 31 and ultimately adjusting the overall angle of the placement assembly 3. Before the operator places the tubular drill bit 24 onto the placement assembly 3, the length of the second drive hydraulic cylinder 37 is adjusted to tilt the placement assembly 3, reducing the height of the second mounting plate 35 relative to the ground. This allows the operator to place the tubular drill bit 24 at an angle onto the fixing member 32, reducing the difficulty of placing the tubular drill bit 24 and improving the ease of placement.

[0059] After the tubular drill string 24 is placed, the angle of the tubular drill string 24 is adjusted by adjusting the length of the second drive hydraulic cylinder 37 so that the tubular drill string 24 can be installed on the tunneling assembly 2.

[0060] The implementation principle of a geological exploration drilling rig in this application embodiment is as follows: the tubular drill bit 24 is placed on the machine body 1. Before using the geological exploration drilling rig for geological exploration and excavation, the machine body 1 is moved to the exploration site, and then the tubular drill bit 24 is installed on the placement component 3. The replacement of the tubular drill bit 24 and the geological exploration work are realized through the cooperation of the excavation component 2 and the placement component 3. The replacement of the tubular drill bit 24 is carried out by machinery instead of manual labor, which reduces the difficulty of drill rod disassembly and replacement and casing extension operations, and improves the efficiency of drill rod disassembly and replacement and casing extension operations.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
