[0049] The following is combined Figures 1 to 12 The following describes embodiments of the present invention.

[0050] According to an embodiment of the present invention, a well drilling rig is provided, comprising: a transport vehicle assembly 1; a main unit assembly 5, which is detachably connected to the transport vehicle assembly 1 via a rotating shaft assembly 2; the main unit assembly 5 having a transport state in which it is driven to be horizontally placed on the transport vehicle assembly 1 under the action of the rotating shaft assembly 2, and an installation state in which it is driven to be vertically placed under the action of the rotating shaft assembly 2; and a pump station assembly 7 having a drive wheel assembly for movement, which is detachably connected to the transport vehicle assembly 1 and is used to provide driving force for the main unit assembly 5.

[0051] In this embodiment, the main unit assembly 5 is detachably connected to the transport vehicle assembly 1 via the pivot assembly 2. During transportation, the pivot assembly 2 drives the main unit assembly 5 to be placed horizontally on the transport vehicle assembly 1 for easy transport. The transport vehicle assembly 1 simultaneously transports the main unit assembly 5 and the pump station assembly 7. After the transport vehicle assembly 1 adjusts the main unit assembly 5 to the predetermined working position, the pivot assembly 2 drives the main unit assembly 5 to be placed vertically, so that the bottom of the main unit assembly 5 contacts the ground at the predetermined working position. Then, the main unit assembly 5 is disassembled from the pivot assembly 2 to achieve rapid installation of the main unit assembly 5. Next, the pump station assembly 7 is disassembled and moved to the predetermined position via the drive wheel assembly to provide driving force for the main unit assembly 5 for rapid deployment. No other auxiliary equipment is required, making it simple, fast, efficient, and safe. The transport vehicle assembly 1, the main unit assembly 5, and the pump station assembly 7 are independent of each other. After installation, the transport vehicle assembly 1 can be moved to another location to continue operation, reducing the space requirements of the main unit assembly 5 at the working location, improving work efficiency, and providing strong terrain adaptability.

[0052] In one embodiment, such as Figures 2 to 5As shown, the rotating shaft assembly 2 includes a first frame 201, a second frame 202, a first telescopic member 203, and a second telescopic member 204. The first frame 201 can be rotatably connected to the transport vehicle assembly 1 in a horizontal direction. One end of the second frame 202 is rotatably connected to the end of the first frame 201 away from the transport vehicle assembly 1, and the other end is a free end. One end of the first telescopic member 203 is hinged to the transport vehicle assembly 1, and the other end is hinged to the end of the first frame 201 close to the transport vehicle assembly 1. One end of the second telescopic member 204 is hinged to the transport vehicle assembly 1, and the other end is hinged to the second frame 202. The main unit assembly 5 is detachably connected to the second frame 202.

[0053] It should be noted that the second frame 202 has the ability to rotate to a horizontally placed conveying state under the action of the first telescopic member 203 and the second telescopic member 204, and to rotate to a vertically placed installation state; the rotation center of the first frame 201 and the transport vehicle assembly 1 is at a preset distance from its end; the rotation axis of the second frame 202 is parallel to the rotation axis of the first frame 201.

[0054] In this embodiment, the main unit assembly 5 is detachably connected to the second frame 202 via the first frame 201 and the second frame 202. When transporting the main unit assembly 5, the first telescopic member 203 is shortened, causing the end of the first frame 201 connected to the second frame 202 to rotate upward around the horizontal direction, thereby raising the second frame 202 and the main unit assembly 5. At the same time, the second telescopic member 204 is retracted, causing the free end of the second frame 202 to rotate towards the first frame 201, thereby causing the main unit assembly 5 to change to a horizontal position. The main unit assembly 5 is adjusted to the transport state. When installation is required, the first telescopic component 203 is extended, causing the end connecting the first frame 201 and the second frame 202 to rotate downwards, thereby lowering the second frame 202 and the main unit assembly 5. Simultaneously, the second telescopic component 204 is extended, causing the free end of the second frame 202 to rotate away from the first frame 201, thus changing the main unit assembly 5 to a vertical position. This adjusts the main unit assembly 5 to the installation state, places it on the ground, and then disassembles it to complete the installation, which is convenient and quick. The adjustment using the first frame 201 and the second frame 202, in conjunction with the first telescopic component 203 and the second telescopic component 204, improves stability and convenience.

[0055] Specifically, both the first telescopic member 203 and the second telescopic member 204 can be selected as hydraulic telescopic rods.

[0056] In one embodiment, such as Figure 3 and Figure 5 As shown, a pin hole 4 is provided at the connection between the second frame 202 and the first frame 201, and the bottom end of the main unit assembly 5 is detachably connected to the pin hole 4 through a pin shaft 3.

[0057] In this embodiment, by installing the bottom end of the main unit assembly 5 at the connection between the second frame 202 and the first frame 201 through the engagement of the pin 3 and the pin hole 4, it is convenient to lower the bottom end of the main unit assembly 5 to the ground when the first telescopic member 203 drives the end of the first frame 201 connected to the second frame 202 to descend. The engagement of the pin 3 and the pin hole 4 improves the efficiency of installation and disassembly, thereby improving work efficiency.

[0058] In one embodiment, such as Figures 6 to 11 As shown, the main unit assembly 5 includes: a base 501, which is detachably connected to the rotating shaft assembly 2; multiple guide columns 502, which are vertically arranged on the base 501; a drive assembly, which is slidably connected to the guide columns 502 through a guide sleeve 506, for driving the drill pipe to rotate; and multiple propulsion cylinders 503, which are connected at both ends to the drive assembly and the base 501 respectively, and are drivenly connected to the pump station assembly 7, for driving the drive assembly to rise and fall in the vertical direction.

[0059] In this embodiment, after the base 501 is installed in the working position, the drill pipe can be driven to rotate by the drive assembly to carry out the operation. At the same time, the pump station assembly 7 provides driving force, and the drive assembly is driven by the propulsion cylinder 503 to slide and adjust the lifting and lowering along the guide column 502 to facilitate the completion of drilling operations.

[0060] In one embodiment, such as Figures 6 to 11 As shown, there are four propulsion cylinders 503, which are arranged in a rectangular shape.

[0061] In this embodiment, four propulsion cylinders 503 are arranged in a rectangular shape to improve the stability of the lifting process and ensure the driving force during the lifting process.

[0062] In one embodiment, such as Figures 6 to 11 As shown, the drive assembly includes a gearbox 504 and a motor 505. The gearbox 504 is slidably connected to the guide post 502 via a guide sleeve 506. The output end of the motor 505 is connected to the input end of the gearbox 504.

[0063] In this embodiment, the motor 505 provides driving force to the reduction gearbox 504, which in turn drives the drill rod to rotate for operation.

[0064] In one embodiment, such as Figures 6 to 8 As shown, there are two motors 505, and the two motors 505 are symmetrically arranged on the gearbox 504.

[0065] In this embodiment, two motors 505 are provided to drive the gearbox 504, increasing output performance and facilitating large-diameter well operations.

[0066] As a possible implementation method, it can also be, for example... Figures 9 to 11 As shown, four motors 505 are provided, and the four motors 505 are arranged in a rectangular shape on the gearbox 504. By providing four motors 505, the gearbox 504 is further driven, the output performance is increased, and large-diameter well operations are realized.

[0067] In one embodiment, such as Figure 6 and Figure 9 As shown, the main unit assembly 5 also includes a robotic arm assembly 6, which is mounted on the base 501 and is used to clamp and move the drill rod.

[0068] In this embodiment, a robotic arm assembly 6 is added to facilitate the clamping and movement of the drill rod, making disassembly and installation easier.

[0069] In one embodiment, such as Figure 12 As shown, the pump station assembly 7 includes a pump station body 701 and a connecting rod 702; one end of the connecting rod 702 is foldable and connected to the pump station body 701, and the other end is provided with a connecting hole 703 for detachable connection with the transport vehicle assembly 1.

[0070] It should be noted that the connecting rod 702 is rotatably mounted on the pump station body 701, and has a first state of rotating to a horizontal position, and a second state of rotating and folding to fit against the pump station body 701.

[0071] In this embodiment, during connection, the pump station body 701 is placed horizontally via the connecting rod 702 and connected to the transport vehicle assembly 1 via the connecting hole 703 using bolts or pins 3, which facilitates installation and disassembly. After disassembly, it can be folded back to avoid affecting the use of the pump station body 701.

[0072] In one embodiment, such as Figure 12 and Figure 13 As shown, a limiting ring 704 is hinged on the connecting rod 702, and a hook 705 is provided on the pump station body 701 corresponding to the limiting ring 704, which is used to fit and engage the connecting rod 702 with the hook 705 through the limiting ring 704 when the connecting rod 702 is folded.

[0073] In this embodiment, when the connecting rod 702 is folded, the limiting ring 704 is engaged with the hook 705 to limit the connection rod 702 and prevent it from becoming loose and affecting its use. When it needs to be connected to the transport vehicle assembly 1, the limiting ring 704 can be disengaged from the hook 705, which is convenient and quick.

[0074] Specifically, such as Figure 5As shown, the transport vehicle assembly 1 includes a support frame, a track assembly, and an operating cabin mounted on the support frame; a pivot assembly 2 is mounted on the support frame; the track assembly is mounted on the support frame to facilitate movement; both the track assembly and the pivot assembly 2 are communicatively connected to the operating cabin to control the movement of the track assembly and to control the mounting of the main unit assembly 5 on the pivot assembly 2 via the operating cabin.

[0075] Specifically, the support frame has an installation port in the vertical direction corresponding to the first frame 201, so as to provide space for the first frame 201 to drive the main unit assembly 5 to lift and adjust at the end away from the transport vehicle assembly 1.

[0076] The specific working principle of the well drilling rig provided in this embodiment is as follows: During transportation, by shortening the first telescopic member 203 and the second telescopic member 204, the end connecting the first frame 201 and the second frame 202 rotates upward around the horizontal direction, thereby lifting the second frame 202 and the main assembly 5. At the same time, the free end of the second frame 202 rotates towards the first frame 201, thereby driving the main assembly 5 to change to a horizontal position, thus adjusting the main assembly 5 to the transportation state. Meanwhile, the pump station body 701 is connected to the transport vehicle assembly 1 through the leveling connecting rod 702. The transport vehicle assembly 1 simultaneously transports the main assembly 5 and the pump station assembly 7. After the transport vehicle assembly 1 moves the main assembly 5 to the predetermined working position, it controls the extension of the first telescopic member 203 and the second telescopic member 204, causing the end connecting the first frame 201 and the second frame 202 to rotate downward, thereby... The second frame 202 and the main assembly 5 are lowered. Simultaneously, the free end of the second frame 202 rotates away from the first frame 201, causing the main assembly 5 to change to a vertical position. This adjusts the main assembly 5 to the installation position and places it on the ground. After removing the pin 3, installation is complete. Simultaneously, the pump station assembly 7 is disassembled and moved to a predetermined position via the drive wheel assembly, providing driving force to the main assembly 5. The motor 505 provides torque to the reduction gearbox 504 to rotate the drill pipe. The drilling depth is adjusted in conjunction with the propulsion cylinder 503 for rapid deployment. No other auxiliary equipment is required; the process is simple, fast, efficient, and safe. The transport vehicle assembly 1, the main assembly 5, and the pump station assembly 7 are independent. After installation, the transport vehicle assembly 1 can be moved to another location to continue operation, reducing the space requirements of the main assembly 5 at the work site, improving work efficiency, and providing strong terrain adaptability. This solves the problems of existing well drilling rigs, which have high integration, cannot operate independently, occupy a large overall space, have large space requirements at the work site, and have poor terrain adaptability.
