Description

Technical Field

[0001] This utility model relates to the field of oil drilling tool technology, and in particular to a fully hydraulic drilling shock absorber. Background Technology

[0002] Oil drilling tools are a series of specialized instruments that ensure the smooth operation of oil drilling operations. They encompass various types, each with its unique purpose. Drill bits, as the core component that directly breaks rock, have different designs and materials adapted to various formation conditions, responsible for opening the borehole path. In oil drilling operations, complex downhole conditions often lead to problems such as drill string sticking, severely impacting the operation progress. Because traditional slammers have limitations in response speed and precise control of impact force, they are ill-suited to the increasingly complex drilling environment. Therefore, a fully hydraulic slammer is needed.

[0003] The fully hydraulic drilling rig is a key downhole tool used in oil drilling engineering. In the past, matching threads were usually machined on the rig base and the bottom of the rig or other connecting parts to tighten them together. This method of installation and disassembly is difficult and time-consuming, and affects the maintenance of the internal components of the rig. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fully hydraulic drilling oscillator, which aims to improve the problem that machining matching threads on the oscillator base and the bottom of the oscillator and screwing them together is difficult and time-consuming.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Preferably, the limiting component includes a fixing block, the lower surface of which is fixedly connected to the inner wall of the sleeve, and the outer wall of which is slidably connected to the inner wall of the Z-shaped frame.

[0008] Preferably, the outer wall of the limiting sleeve is slidably connected to the inside of the sleeve, and the upper surface of the base is disposed on the lower surface of the sleeve.

[0009] Preferably, the outer wall of the sleeve is slidably connected with a first outer shell and a second outer shell, and the outer wall of the first outer shell is attached to the outer wall of the second outer shell.

[0010] Preferably, a fixing plate is fixedly connected to the outer wall of the first outer shell, and the outer wall of the fixing plate is slidably connected to the inside of the second outer shell.

[0011] Preferably, a T-shaped frame is slidably connected inside the second outer shell, and a fixed rod is rotatably connected inside the T-shaped frame. Both ends of the fixed rod are fixedly connected to U-shaped blocks, and the lower surface of the U-shaped blocks is disposed on the upper surface of the second outer shell.

At the same time, it is convenient for workers to remove the base and maintain the internal components of the sleeve.

[0016] 2. In this utility model, the outer shell 1 and outer shell 2 are quickly installed and disassembled through the cooperation between the fixing plate, T-shaped frame, fixing rod, U-shaped block, spring 2 and limiting plate, which reduces the impact of the shock absorber on the surrounding rocks during operation, thereby extending the service life of the shock absorber.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a fully hydraulic drilling breaker, comprising a sleeve 1, a hydraulic assembly 2 disposed inside the sleeve 1, a connecting sleeve 3 at the top of both the sleeve 1 and the hydraulic assembly 2, a limit sleeve 4 at the bottom of the hydraulic assembly 2, a base 5 fixedly connected inside the limit sleeve 4, a T-shaped rod 6 slidably connected inside the sleeve 1, a fixing seat 7 fixedly connected to the outer wall of the T-shaped rod 6, a spring 8 fixedly connected to the outer wall of the fixing seat 7, and the outer wall of the spring 8 fixedly connected to the inner wall of the sleeve 1. A slide rail 9 is fixedly connected to the upper surface. The outer wall of the slide rail 9 is slidably connected to the inside of the sleeve 1. An L-shaped frame 10 is rotatably connected to the outer wall of the fixed base 7. A Z-shaped frame 11 is rotatably connected to the outer wall of the L-shaped frame 10. The outer wall of the Z-shaped frame 11 is slidably connected to the inside of the sleeve 1. The outer wall of the Z-shaped frame 11 is slidably connected to the inside of the base 5. A limit component is provided on the inner wall of the sleeve 1. The limit component includes a fixing block 12. The lower surface of the fixing block 12 is fixedly connected to the inner wall of the sleeve 1. The outer wall of the fixing block 12 is slidably connected to the inner wall of the Z-shaped frame 11.

[0025] Specifically, the movement of the T-shaped rod 6 is initially limited by the inside of the sleeve 1. The T-shaped rod 6 drives the fixed seat 7 to move. The slide rail 9 supports and restricts the movement of the fixed seat 7, thereby further limiting the T-shaped rod 6. The elastic force of the spring 8 passes through the fixed seat 7 and the L-shaped frame 10, thereby pressing against the Z-shaped frame 11 inside the base 5, achieving the installation effect of the base 5. The base 5 is installed inside the sleeve 1, and the limiting sleeve 4 is set to be elastic, thereby pressing against the connection between the limiting sleeve 4 and the hydraulic assembly 2, reducing the vibration generated by the operation of the hydraulic assembly 2 and the connecting cylinder 3, thereby protecting the hydraulic assembly 2. The movement of the Z-shaped frame 11 is supported and restricted by the inside of the fixed block 12 and the sleeve 1.

[0026] Reference Figure 3 The outer wall of the limiting sleeve 4 is slidably connected to the inside of the sleeve 1, and the upper surface of the base 5 is set on the lower surface of the sleeve 1.

[0027] Specifically, the base 5 is convex and the limiting sleeve 4 is concave, which makes it easy to install the limiting sleeve 4 inside the sleeve 1 using the base 5. The limiting sleeve 4 and the base 5 are fixed by friction, which makes it easy to replace the limiting sleeve 4.

[0028] Reference Figure 1 The outer wall of sleeve 1 is slidably connected with outer shell 13 and outer shell 2 14, and the outer wall of outer shell 13 is attached to the outer wall of outer shell 2 14.

[0029] Specifically, the outer wall of the sleeve 1 is provided with protrusions to prevent shaking or positional displacement of the outer casing 13 and the outer casing 2 14 after installation, thereby improving the stability of the installation of the outer casing 13 and the outer casing 2 14.

[0030] Reference Figure 4 A fixing plate 15 is fixedly connected to the outer wall of outer shell 13, and the outer wall of fixing plate 15 is slidably connected to the inside of outer shell 14. A T-shaped frame 16 is slidably connected inside outer shell 14, and a fixing rod 17 is rotatably connected inside T-shaped frame 16. U-shaped blocks 18 are fixedly connected to both ends of fixing rod 17, and the lower surface of U-shaped blocks 18 is set on the upper surface of outer shell 14. A spring 19 is fixedly connected to the upper surface of T-shaped frame 16, and the outer wall of spring 19 is fixedly connected to the inner wall of outer shell 14. A limit plate 20 is fixedly connected to the lower surface of T-shaped frame 16, and the outer wall of limit plate 20 is slidably connected to the inside of fixing plate 15.

[0031] Specifically, a handle is provided on the outer wall of the U-shaped block 18 for easy manipulation. When the U-shaped block 18 is manipulated, the T-shaped frame 16 is driven through the fixing rod 17. The movement of the T-shaped frame 16 is restricted by the interior of the outer shell 14. Under the elastic force of the spring 19, the T-shaped frame 16 is held in place, thereby providing a downward force to the U-shaped block 18, causing the U-shaped block 18 to fit against the outer shell 14. The T-shaped frame 16 slides inside the outer shell 14, restricting the movement of the limiting plate 20. The fixing plate 15 slides inside the outer shell 14, achieving the positioning effect for the installation of the outer shell 13 and the outer shell 14.

[0032] Working principle: When using this shock absorber, the connecting sleeve 3 is connected to the drill bit. Through the hydraulic assembly 2 inside the sleeve 1, the drill bit is driven to perform drilling work. The outer shell 13 and the outer shell 2 14 wrap around the outer wall of the sleeve 1. At the same time, the outer shell 13 and the outer shell 2 14 are in contact. The U-shaped block 18 is moved to the vertical direction, which drives the T-shaped frame 16 to move upward through the fixing rod 17. This compresses the spring 2 19. The T-shaped frame 16 drives the limiting plate 20 to move upward, allowing the fixing plate 15 to slide into the inside of the sleeve 1. Then, the U-shaped block 18 is moved to the horizontal direction, which releases the T-shaped frame 16. Under the elastic force of the spring 2 19, the limiting plate 20 moves downward, which slides into the inside of the fixing plate 15 for limiting. The protrusions on the outer wall of the sleeve 1 prevent the outer shell 13 and the outer shell 2 14 from shifting, thus achieving the protective effect of the sleeve 1.

[0033] When it is necessary to inspect the internal components of sleeve 1, pull the T-shaped rod 6 to move the fixed seat 7 and slide rail 9 forward, compress the spring 8, and use the fixed seat 7 to drive the L-shaped frame 10 to rotate forward and move to the left. Under the action of the fixed block 12 and the inside of sleeve 1, the L-shaped frame 10 drives the Z-shaped frame 11 to move to the left. When it moves to the leftmost side inside the base 5, it is no longer limited. Pull the base 5 down to facilitate the maintenance of the internal components of sleeve 1. The limit sleeve 4 is used to reduce the vibration generated by the operation of the hydraulic assembly 2.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
