Description

Technical Field

[0001] This utility model relates to the field of shock absorber locking technology, and in particular to a fully hydraulic shock absorber locking device to prevent accidental shocks. Background Technology

[0002] A fully hydraulic shock absorber is a device that generates impact force through hydraulic power. It uses changes in hydraulic oil pressure to drive the movement of its internal structure, thereby producing shock force. It is widely used in oil drilling, geological exploration, and other fields, primarily to handle stuck drill bit accidents. The powerful shock force it generates helps to release the drill string from the wellbore, ensuring the smooth progress of drilling operations.

[0003] Existing fully hydraulic shock absorber locking devices mostly employ a mechanical structure, typically controlling the flow and interruption of hydraulic oil through manually adjusted valves. This type of device is relatively simple in structure and lacks the ability for automatic adjustment and precise control.

[0004] Existing locking devices are not only inefficient in operation, but also in complex downhole working environments, they are unable to quickly and accurately control the hydraulic oil flow according to the actual working conditions, and cannot effectively avoid the phenomenon of false vibration caused by unstable hydraulic oil flow.

The flow control component includes a motor 5, which provides stable and adjustable power output to ensure the stability and accuracy of power transmission. The motor 5 is fixedly connected to the outside of the pipe 1. A rotating shaft 6 is fixedly connected to the output end of the motor 5, and a bevel gear 9 is fixedly connected to the other end of the rotating shaft 6. A bevel gear 10 is rotatably connected inside the protective box 7. The protective box 7 is a closed metal box, and the bevel gear 10 is rotatably connected inside it via bearings to ensure that the bevel gear 10 can rotate flexibly. The bevel gear 9 and the bevel gear 10 mesh with each other. A round rod 11 is fixedly connected inside the bevel gear 10, and a [missing information - likely a component or component] is fixedly connected to the bottom of the round rod 11. When the bevel gear 10 rotates, the semicircular plate 12 can drive the round rod 11 and the semicircular plate 12 to rotate synchronously. A locking block 13 is fixedly connected to the outside of the semicircular plate 12. The locking block 13 is made of wear-resistant material, which can reduce friction with the inner wall of the pipe. A fixing plate 14 is fixedly connected to the inside of the pipe 1. The locking block 13 is rotatably connected to the inner wall of the pipe 1. Multiple fixing brackets 8 are fixedly connected to the outside of the protective box 7. The other end of the multiple fixing brackets 8 is fixedly connected to the inner wall of the pipe 1. The multiple fixing brackets 8 are distributed around the protective box 7. This structure can firmly fix the protective box 7 to the pipe 1 and ensure the stability of the internal transmission structure of the protective box 7.

[0013] Reference Figure 4 , Figure 5 and Figure 6 The fixing component includes a pin 15, which is slidably connected inside the pipe 1. A spring 16 is sleeved on the outside of the pin 15. The spring 16 is a high-strength compression spring with good elastic restoring force. One end of the pin 15 is fixedly connected to a movable plate 17. An electric push rod 18 is fixedly connected to the outside of the pipe 1. The output end of the electric push rod 18 is fixedly connected to the bottom of the movable plate 17. The electric push rod 18 can drive the movable plate 17 to perform stable linear motion. A movable block 27 is slidably connected inside the pipe 1. A circular groove 19 is opened inside the movable block 27. The pin 15 and the circular groove 19 are engaged with each other.

[0014] Reference Figure 1 and Figure 4The outer side of pipe 1 is fixedly connected to protective boxes 2 and 3.

Two rings 26 are fixedly connected to the middle of the connecting rod 25. A movable chamber 24 is fixedly connected inside the pipe 1. The rings 26 are slidably connected inside the movable chamber 24, which limits the movement of the rings 26, thus ensuring the sliding direction of the connecting rod 25 and the conical head 20. Two fixed rings 23 are fixedly connected inside the pipe 1, which limits the movement of the spring 22, preventing it from shifting during compression and extension. A movable block 27 is fixedly connected to the bottom of the connecting rod 25, and a connector 28 is fixedly connected to the bottom of the movable block 27. The connector 28 is used to connect to external equipment, facilitating the installation and use of the device.

[0015] Working principle: First, when it is necessary to control the flow rate, start motor 5, drive shaft 6 to rotate, thereby driving bevel gear 9 and bevel gear 10 to rotate, and semicircular plate 12 to rotate, so that semicircular plate 12 and fixed plate 14 fit together, which can control the flow rate of hydraulic oil. After the vibration ends, close semicircular plate 12 and fixed plate 14 to prevent hydraulic oil from flowing in, reducing the possibility of false vibration from the source.

[0016] Secondly, when vibration is required, activate the electric push rod 18 to push out the movable plate 17, stretch the spring 16, and lift the pin 15. After the vibration is completed, retract the electric push rod 18, release the spring 16, and the pin 15 will quickly pop out and insert into the circular groove 19 to quickly complete the fixation and prevent accidental vibration.
