Description

Technical Field

[0001] The invention relates to the technical field of petroleum instrument disassembly, and in particular to a hydraulic integrated disassembly device for a rotary guide system. Background Art

[0002] The bearing inner sleeve and inner magnetic steel components of the rotary guide system are assembled at the outer circle installation position of the upper spindle by the hot-installation process. The instrument is affected by environmental factors such as high temperature, high pressure, and drilling fluid erosion during downhole operation, and the solid particles of the drilling fluid are deposited in the assembly gap between the upper spindle and the mounting parts, which makes the mounting parts and the outer wall of the upper spindle have a very large contact force, making it very difficult to disassemble the bearing inner sleeve and inner magnetic steel. Conventional disassembly technology is cumbersome, time-consuming, and has limited disassembly pressure. In special circumstances, it cannot be disassembled and can only be disassembled destructively, resulting in damage to the upper spindle, bearing inner sleeve and inner magnetic steel, causing serious economic losses.

The device meets the disassembly requirements of internal components, and is easy to operate, time-saving and efficient. However, after careful analysis, it was found that the device can only meet the disassembly needs of the internal components of the drill collar, and can only meet the installation needs of the components to be disassembled with a threaded structure. In addition, the mechanical intelligence level of the device is insufficient, and the disassembly force and disassembly stroke cannot be intuitively observed, resulting in it being unable to meet the effective disassembly and assembly of hot-mounted bearing inner sleeves, internal magnetic steel, etc. on the upper spindle.

[0034] Specifically, the hydraulic electromagnetic pump 25 provides driving force; the circuit controller 26 controls the lifting and lowering of the locking plate 15 on the auxiliary support seat 3 and the extension and retraction of the plunger of the main hydraulic cylinder 5; the operation button 27 makes the opening and closing of the locking plate 15 on the auxiliary support seat 3 and the extension and retraction of the plunger of the main hydraulic cylinder 5 operable, and realizes specific control through the button; the display screen 28 displays the disassembly size and disassembly stroke size, and the display screen 28 can display the pressure size and changes at the plunger in real time, and feedback the plunger stroke data; The present embodiment does not limit the structures of the main support seat 2 and the auxiliary support seat 3, and any existing conventional structure having the above functions may be adopted.

[0035] Taking the disassembly of the inner sleeve of the bearing that is heat-fitted on the upper spindle in the rotary guide system as an example, the disassembly principle of this embodiment is as follows: like Fig. 9As shown, when disassembling, first press the operation button 27, and control the locking plate 15 on the auxiliary support seat 3 to rise through the hydraulic controller 4 and the hydraulic assembly 16, so that the auxiliary support seat 3 is in an unlocked state, and the workpiece 30 to be disassembled can enter the auxiliary support seat 3. Place the upper spindle into the integrated base 1, with the male thread end facing the main hydraulic cylinder 5, and the slender shaft with a smaller outer diameter at the end of the upper spindle is placed on the auxiliary support seat 3 close to the main hydraulic cylinder 5, supported by the radial roller 14, and the end with a larger outer diameter is placed on the other auxiliary support seat 3, supported by the radial roller 14; press the operation button 27 to control the locking plate 15 on the auxiliary support seat 3 to move downward to lock the upper spindle to be disassembled. At the same time, use the main support seat 2 to fix the inner sleeve of the bearing to be disassembled on the upper spindle; install the replaceable top block 6 in the front mounting hole of the plunger of the main hydraulic cylinder 5, and install the force sensor 9 at the front end of the replaceable top block 6.

[0036] The main hydraulic cylinder 5 is connected to the hydraulic electromagnetic pump 25 through the high-pressure oil pipe 7, and the operation button 27 is pressed to control the hydraulic electromagnetic pump 25 to pump out the hydraulic oil, so that the plunger of the main hydraulic cylinder 5 extends out, and the hydraulic driving force is initiated by the hydraulic electromagnetic pump 25, and is transmitted to the inner sleeve of the bearing of the upper spindle to be disassembled through the high-pressure oil pipe 7, the main hydraulic cylinder 5, the replaceable top block 6, the force sensor 9, the integrated base 1, and the main support seat 2. The inner sleeve of the bearing to be disassembled and the upper spindle are relatively displaced; the display screen 28 on the hydraulic drive-control integrated platform 8 is observed to display the disassembly force and disassembly stroke, and the disassembly force is ensured to be within a controllable range during the operation; when the disassembly stroke is reached, the disassembly is completed; the operation button 27 is pressed to control the plunger of the main hydraulic cylinder 5 to be retracted, and the locking plate 15 on the auxiliary support seat 3 is controlled to move upward to release the lock, loosen the main support seat 2, take out the upper spindle and the disassembled inner sleeve of the bearing, and the disassembly process is completed.

[0037] The hydraulic integrated disassembly device for the rotary guide system provided in this embodiment integrates hydraulic and control technologies, can observe the disassembly stress and disassembly stroke, can set a self-use pressure relief threshold, and has extremely high safety and operability.

[0038] Example 2 As a preferred embodiment of the present invention, this embodiment further optimizes the structures of the auxiliary support seat 3 and the main support seat 2 based on the embodiment 1.
