Description

Technical Field

[0001] The utility model relates to the technical field of petroleum drilling machinery, in particular to a high-frequency vibration type oil well drill bit. Background Art

[0002] Oil drilling first requires drilling operations on the surface above the oil layer. In the process, oil well drill bits are needed, which mainly include pear-shaped milling cone drill bits, bottom three-cone drill bits, single-cone drill bits, eye-point drill bits, triangular drill bits, etc. During the drilling process, the drill bit is in direct contact with the rock and soil layer, and the rock and soil structure on the surface is broken by the rotation force. Therefore, the oil well drill bit is usually severely worn, and the cost of drilling is very high.

[0003] During the drilling process, the vibration state of the drill bit may change due to changes in geological conditions and increased drilling depth. The drill bit in the existing technology cannot maintain a stable vibration effect, and the life of the drill bit will be reduced. At the same time, during the drilling process, dust and impurities will enter the mechanical structure, affecting the cleanliness and stable operation of the device. Utility Model Content

[0004] The purpose of the utility model is to provide a high-frequency vibration oil well drill bit to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an installation body, wherein the installation body is fixedly connected to a motor on the outside, a sliding rod is provided at the output end of the motor, the sliding rod is fixedly connected to a second threaded rod on the outside, the sliding rod is rotatably connected to the installation body, the installation body is fixedly connected to a first hanging ear on the outside, the first hanging ear is rotatably connected to a gear on the outside, the gear and the second threaded rod are meshingly connected, the sliding rod is fixedly connected to a spring on the outside, the sliding rod is rotatably connected to a second crank on the outside, the gear is fixedly connected to a cam on the outside, the cam and the second crank are rotatably connected, and the second crank is rotatably connected to the installation body; the sliding rod is slidably connected to a connecting rod on the outside, a drill bit is fixedly connected to the connecting rod on the outside, a protective disc is slidably connected to the drill bit on the outside, the protective disc is fixedly connected to the installation body, and the installation body is threadedly connected to a drill rod on the outside.

[0006] Preferably, a second hanging ear is fixedly connected to the outside of the installation body, a sliding rod is rotatably connected to the outside of the second hanging ear, and the sliding rod is rotatably connected to the installation body via the second hanging ear.

[0007] Preferably, a rotating disk is fixedly connected to the outside of the connecting rod, a second crank is rotatably connected to the outside of the rotating disk, and the second crank is rotatably connected to the connecting rod via the rotating disk.

[0008] Preferably, a first threaded rod is fixedly connected to the outside of the drill rod, a mounting body is threadedly connected to the outside of the first threaded rod, and the mounting body and the drill rod are threadedly connected via the first threaded rod.

[0009] Preferably, a cable is fixedly connected to the outside of the motor.

[0010] Preferably, a first crank is fixedly connected to the outside of the cam, a second crank is rotatably connected to the outside of the first crank, and the second crank is rotatably connected to the cam through the first crank.

[0011] Compared with the prior art, the utility model has the following beneficial effects: when in use, because a sliding rod is provided at the output end of the motor, the staff first threadedly connects the drill rod to the installation body, and then controls the rotation of the motor to rotate the sliding rod. Since the second threaded rod is meshed with the gear, the first crank drives the cam to rotate, thereby driving the second crank to rotate, causing the connecting rod slidably connected to the sliding rod to vibrate. Since the rotation of the gear is stable, the vibration state of the connecting rod remains stable, thereby ensuring that the drilling effect can be controlled and the life of the drill bit can be extended. At the same time, since the protective disc is slidably connected to the connecting rod, dust and impurities will not enter the interior of the device during the drilling process, so that the device can work stably.

[0024] Because the motor 7 is fixedly connected to the mounting body 3, a sliding rod 18 is provided at the output end of the motor 7, the sliding rod 18 is fixedly connected to the second threaded rod 8, and the second threaded rod 8 is meshedly connected to the gear 9, the gear 9 is fixedly connected to the cam 11, and the cam 11 is rotationally connected to the second crank 13 through the first crank 10. The staff starts the motor 7, so that the second crank 13 drives the connecting rod 6 to move up and down, thereby driving the drill bit 5 to rotate and vibrate at the same time, so that the vibration effect can be guaranteed.

[0025] Embodiment 2

[0026] On the basis of Example 1, the sliding rod 18 is externally slidably connected to the connecting rod 6, the connecting rod 6 is externally fixedly connected to the drill bit 5, the drill bit 5 is externally slidably connected to the protective disc 15, the protective disc 15 is fixedly connected to the installation body 3, the installation body 3 is externally threadedly connected to the drill rod 1; the drill rod 1 is externally fixedly connected to the first threaded rod 2, the first threaded rod 2 is externally threadedly connected to the installation body 3, and the installation body 3 and the drill rod 1 are threadedly connected via the first threaded rod 2; the motor 7 is externally fixedly connected to the cable 4; the cam 11 is externally fixedly connected to the first crank 10, the first crank 10 is externally rotatably connected to the second crank 13, and the second crank 13 and the cam 11 are rotationally connected via the first crank 10.

[0027] Because the connecting rod 6 is slidably connected to the sliding rod 18, the protective disc 15 is slidably connected to the connecting rod 6, and the connecting rod 6 is fixedly connected to the drill bit 5, during the drilling process, the sliding connection between the protective disc 15 and the connecting rod 6 refers to the interface design between two key components in the drilling device. This design allows the two components to move relative to each other during the drilling process while maintaining close contact and sealing, which can prevent pollutants from the external environment from entering, and prevent dust and impurities from entering the interior of the device, so that the device can work stably.

[0028] When the utility model is in use, since the output end of the motor 7 is provided with a sliding rod 18, the staff firstly threadedly connects the drill rod 1 with the mounting body 3, and then controls the rotation of the motor 7 to rotate the sliding rod 18. Since the second threaded rod 8 is meshedly connected with the gear 9, the first crank 10 drives the cam 11 to rotate, thereby driving the second crank 13 to rotate, so that the connecting rod 6 slidably connected with the sliding rod 18 vibrates. Since the rotation of the gear 9 is stable, the vibration state of the connecting rod 6 remains stable, thereby ensuring that the drilling effect can be controlled and the service life of the drill bit can be extended. At the same time, since the protective disc 15 is slidably connected with the connecting rod 6, dust and impurities will not enter the interior of the device during the drilling process, so that the device can work stably.
