In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0033] Example 1:

[0034] See also Figure 1-11 A complete set of oil drilling equipment includes a crawler 1, two crawlers 1 are symmetrically distributed, and a connecting beam is set between the two crawlers 1, and a first platform 2 and a second platform 3 are fixed on the connecting beam, wherein the crawler 1 can move under the action of a power system 7, and the crawler 1 is suitable for working environments with relatively soft texture such as deserts, and a plurality of connecting beams are generally provided for supporting the first platform 2 and the second platform 3. A derrick 4 is also provided on the first platform 2, and the second platform 3 is used to place drill pipes. The drill pipes are generally placed on the second platform 3 and transported to the derrick 4 when in use, and are transported through the moving mechanism on the derrick 4. The derrick 4 is also equipped with a lifting mechanism 5 and a driving mechanism 6, and the lifting mechanism 5 is connected to the driving mechanism 6. The driving mechanism 6 is mainly lifted by the lifting mechanism 5. The driving mechanism 6 mainly transmits the power transmitted by the power system 7 and drives the drill pipe to rotate and drill, and can be connected to the circulation system through an external water pump. It is convenient to pass high-pressure water into the well. The circulation system is generally installed on the periphery of this equipment. It is mainly used to collect waste liquid discharged from the drill pipe and clean it. The filtered water can be recycled. The clean water enters the drill bit through the water inlet pipe 692, and the impurities and other waste water generated by the drill bit are taken out of the drill pipe. The first platform 2 is also equipped with a power system 7 and a control room 8. A protective fence 10 is also provided on the first platform 2, and the protective fence 10 wraps the derrick 4. The protective fence 10 is mainly used for protection during the operation to prevent sand, dust or strong winds, and provide a comfortable working environment for the operator. A borehole 11 is also provided on the first platform 2. The borehole 11 is located directly below the drive mechanism 6, and a protective mechanism 9 is installed in the borehole 11. The power system 7 is used to drive the lifting mechanism 5, the drive mechanism 6 and the crawler 1. The general power system uses an engine to generate electricity or transmit power. The control room 8 is used to control the power system 7.

[0035] See Figure 1-3The hoisting mechanism 5 includes a winch 50, a wire rope 51, a brake mechanism 52, and a hook 53. The winch 50 is mounted on the upper portion of the derrick 4, and the wire rope 51 is wound around the winch 50. The wire rope 51 also passes through the brake mechanism 52, which is used to control the lifting speed of the wire rope 51. The wire rope 51 is also connected to the hook 53, which is used to suspend the drive mechanism 6. During operation, the control room 8 can be used to control the power system 7 to transmit the electrical energy generated by the power system 7 to the motor inside the winch 50, thereby controlling the rotation of the winch 50. The rotation drives the wire rope 51 upward or downward, so that the position of the drive mechanism 6 can be controlled at any time. When the drill pipe needs to be replaced, the winch 50 only needs to be started, so that the wire rope 51 drives the hook 53 to rise or fall, thereby driving the drive mechanism 6 to rise and fall. During the drilling process, the bottom of the drive mechanism 6 is connected to the drill pipe, which can drive the drill pipe for drilling.

[0036] See Figure 4-6 The driving mechanism 6 includes a connecting frame 60, a first sleeve seat 61, a coupling seat 62 and a second sleeve seat 63. The first sleeve seat 61 is fixed to the bottom of the connecting frame 60, and the connecting frame 60 is connected to the hook 53, so that the driving mechanism 6 can be lifted as a whole. A limiting sleeve 64 is provided in the middle of the bottom of the first sleeve seat 61, and the limiting sleeve 64 also extends into the coupling seat 62, so that the limiting sleeve 64 can connect the second sleeve seat 63, and the limiting sleeve 64 and the interior of the coupling seat 62 are movable and can rotate while playing a connecting role. The linkage seat 62 is located between the first sleeve seat 61 and the second sleeve seat 63, and a transmission gear ring 65 is also set on the coupling seat 62. When the transmission gear 65 rotates, it will drive the sleeve 66 inside the coupling seat 62 to rotate, and the bottom of the sleeve 66 is fixedly connected to the rotating shaft 690, so that when the transmission When the moving gear 65 rotates, it can drive the rotating shaft 690 to rotate. During the rotation of the rotating shaft 690, the coupling seat 62 will not rotate, and the transmission ring gear 65 is also fixedly connected to the sleeve 66. The sleeve 66 is also located in the coupling seat 62. The coupling seat 62 is also equipped with a ball screw 67, and the ball screw 67 is connected to the transmission system 7. A protective sleeve 68 is installed at the bottom of the second sleeve 63, and a drive head 69 is also installed at the bottom of the protective sleeve 68. The drive head 69 is used to connect with the drill rod and transmit power. The sleeve 66 is also connected to the rotating shaft 690. The rotating shaft 690 passes through the second sleeve 63 and the protective sleeve 68 and is connected to the drive head 69. The rotating shaft 690 is also equipped with an inner tube 691. The top of the inner tube 691 passes through the first sleeve 61 and is connected to the water inlet pipe 692.

[0037] Principle: When drilling is needed, the driving mechanism 6 is first lifted by the lifting mechanism 5, and then the drill rod is passed through the protective mechanism 9 so that the drill rod is extended into the well. Then the driving mechanism 6 is lowered along with the lifting mechanism 5. When it drops to the specified position, the driving head 69 is first installed together with the drill rod spiral. After the installation is completed, drilling is carried out. First, the control room 8 controls the power system 7 to transfer part of the power to the hydraulic oil pump in the form of hydraulic oil. The output end of the hydraulic oil pump is connected to the ball screw 67. The hydraulic oil pump rotates under the action of the hydraulic oil, and the ball screw 67 is driven to rotate during the rotation. The ball screw 67 drives the transmission during the rotation. The ring gear 65 rotates, which drives the sleeve 66 in the coupling seat 62 to rotate, and then drives the rotating shaft 690 and the drive head 69 to rotate, so that the drill pipe can be driven to drill. In this process, since the inner tube 691 is installed in the rotating shaft 690, the inner tube 691 will be movably connected to the top of the drill pipe during the installation of the drill pipe, so that water can be continuously introduced into the drill pipe during the rotation, and impurities are taken out of the well by the water. The driving mechanism 6 replaces the traditional power drive method and can reduce noise and vibration during the rotation drilling process, so that the first platform 2 greatly reduces the vibration, and the suspended operation setting can disperse the vibration of the drill pipe.

[0038] See Figure 5 , a base 693 is fixedly installed on one side of the second seat 63, and a movable rod 694 is provided at the bottom of the base 693. An ear plate 695 is mounted on the movable rod 694, and the ear plate 695 can rotate on the movable rod 694. The ear plate 695 is movably connected to the sliding seat 696, and the sliding seat 696 is slidably mounted on the derrick 4. In this way, under the action of the hook 53, the whole body will move vertically along the derrick 4 under the action of the sliding seat 696. A first hydraulic cylinder 69 is also installed on the sliding seat 696. 7. The telescopic end of the first hydraulic cylinder 697 is also movably connected to the end surface of the side plate 698. The side plate 698 is also provided on the movable rod 694. In this way, the overall angle can be controlled by the first hydraulic cylinder 697. When the angle is rotated, the lifting mechanism 5 is in a relaxed state. The two ends of the movable rod 694 are also movably connected to the bottom of the corresponding second hydraulic cylinder 699. There are no less than two second hydraulic cylinders 699. The telescopic end of each second hydraulic cylinder 699 is also movably connected to the drive head 69. The second hydraulic cylinder 699 is mainly used to reduce the impact of vibration of the drive head 69 during the rotation of the drill pipe.

[0039] See Figure 7-11The protective mechanism 9 includes a protective sleeve 90 and a linkage mechanism 91, wherein the protective sleeve 90 is always located in the borehole 11, and the inner wall of the protective sleeve 90 is provided with a first limiting circular groove 901 and a second limiting circular groove 902, and a movable ring 903 is movably provided in the first limiting circular groove 901 and the second limiting circular groove 902, and the movable ring 903 can rotate in the first limiting circular groove 901 and the second limiting circular groove 902, and an inner gear ring 904 is provided on the inner wall of the movable ring 903, and the inner gear ring 904 rotates under the action of the outer gear ring 905, and the inner gear ring 904 is engaged with the linkage mechanism 91, so that during the rotation of the linkage mechanism 91, the protective sleeve 90 always remains stationary. The protective sleeve 90 is mainly installed in the borehole 11 on the first platform 2. The linkage mechanism 91 can change according to the direct adaptation of the drill rod. During the operation, the stability of the drill rod can be improved. Secondly, there is no need to continuously take out or put the protective mechanism 9 into the borehole 11. It can adapt to drill rods of different diameters and ensure that the connection between the two drill rods will not get stuck when the drill rod is lowered and lifted. This is mainly because the drill rod becomes thinner as it goes down. During the process of lowering or rising of the traditional drill rod, each drill rod will cause wear or be difficult to remove at the borehole 11 due to the connection. The linkage mechanism 91 can ensure the stability of the drill rod. This is mainly because the upper and lower symmetrical settings further ensure that the drill rod will not shake. The protective sleeve 90 is a stepped structure, and handles 926 are also provided on both sides of the protective sleeve 90 to facilitate the overall removal of the protective mechanism 9.

[0040] An outer gear ring 905 is fixedly provided at both the upper and lower ends of the linkage mechanism 91, and the outer gear ring 905 is engaged with the corresponding inner gear ring 904. Through the cooperation between the outer gear ring 905 and the inner gear ring 904, during operation, the drill rod can rotate with the drive head 69, and at the same time, the linkage mechanism 91 can clamp the drill rod for rotation, thereby reducing the wear of the drill hole and improving stability.

[0041] The linkage mechanism 91 includes a first disc 910 and a second disc 911, and the first disc 910 and the second disc 911 are fixedly connected by a plurality of support rods 912, so as to form a symmetrical distribution. A first fixed disc 913 and a second fixed disc 914 are respectively arranged between the first disc 910 and the second disc 911, and the first fixed disc 913 and the second fixed disc 914 both pass through the support rod 912. A plurality of driving rods 915 are circumferentially arranged inside the first disc 910 and the second disc 911, and one end of the driving rod 915 can contact the surface of the drill pipe, and the other end is movably connected to one end of the connecting arm 918, so that the driving rod 915 It can continuously reciprocate and extend along the horizontal direction of the first disc 910 and the second disc 911. A number of grooves 916 are provided on the first fixed disc 913 and the second fixed disc 914. A push rod 917 is provided in each groove 916. A connecting arm 918 is movably equipped on the push rod 917, wherein the push rod 917 mainly plays a connecting role. One end of the connecting arm 918 is movably connected to one end of the driving rod 915, and the other end of the connecting arm 918 is movably connected to one end of the corresponding connecting arm 918 through a hinge rod 919. In this way, the connecting parts of the upper and lower connecting arms 918 can continuously approach or move away from the axis center under the action of the driving rod 915.

[0042] Linkage principle:

[0043] When two drill rods of different diameters are connected, they will extend into the protective mechanism 6 from top to bottom. First, the drill rod will contact the pulley 925. Due to the action of gravity, the drill rod will compress the pulley 925 and drive the driving rod 915 to move from the inside to the outside, that is, compress the driving rod 915. During this process, the pulley 925 is always in contact with the surface of the drill rod. A plurality of circular holes 920 are opened inside the first disc 910 and the second disc 911. The driving rod 915 is fitted in the circular holes 920. A limiting ring 921 is also provided in the circular hole 920, and a collar 922 is fixed on the driving rod 915. A spring 923 is also fitted in the circular hole 920. During the compression process, the spring 923 is in a compressed state. One end of the spring 923 is also fixedly connected to the collar 922, and the spring 923 is seated on the driving rod 915. The limiting ring 921 mainly plays a limiting role to prevent the collar 922 from extending out of the circular hole 920. When the drill pipe connection (a sudden change or a diameter greater than the connection between the upper and lower drill pipes) passes through, the drive rod 915 begins to interact. During the compression of the drive rod 915, the area where the middle connecting arm 918 connects approaches the surface of the drill pipe below. This interaction causes the lower drive rod 915 to extend outward from the circular hole 920 without contacting the drill pipe surface below. The lower drive rod 915 primarily functions during the lifting process. That is, during the upward lifting process, if a sudden change or drill pipe connection is encountered, the drill pipe lowering principle described above is repeated without getting stuck. Furthermore, when the drill pipe is stopped for drilling, the upper or lower portion maintains contact with the drill pipe and rotates as a whole with the drill pipe.

[0044] A rotating sleeve 924 is movably provided at the other end of the driving rod 915, and a pulley 925 is movably provided on the rotating sleeve 924, wherein the pulley 925 is mainly in rolling contact with the drill rod during the process of lowering or lifting, which can reduce the wear on the drill rod, and the number of the driving rods 915 is not less than four. During the rotation operation, the drill rod drives the rotating sleeve 924 to rotate, thereby reducing radial wear and tear, and the pulley is equivalent to reducing axial wear.

[0045] The upper part of the derrick 4 is also fixedly connected to multiple turntables, on which traction ropes 12 are wound. The traction ropes 12 can be stretched as needed. The other end of each traction rope 12 is detachably connected to the first platform 2 and the second platform 3 respectively, and adjacent traction ropes 12 can be arranged with sand-proof nets 13. This can reduce the impact of sand and dust in deserts or dusty environments with frequent sand and dust, protect equipment and provide a comfortable working environment.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
