Description
Technical Field
[0001] This invention relates to the field of bearing assembly tooling technology, and is a rotary guide bearing assembly tooling for petroleum equipment. Background Technology
[0002] In oil drilling engineering, rotary steerable systems are commonly used to guide drilling tools. Currently, rotary steerable drilling technology is the world's most advanced drilling technology and is widely used in the drilling field. Rotary steerable tools can automatically, continuously, and in real-time adjust well inclination and azimuth according to a pre-set wellbore trajectory while the drill string is rotating. It offers high-precision wellbore trajectory control, enabling high-precision closed-loop automated steerable control. Furthermore, rotary steerable systems offer advantages such as low friction, smooth wellbore formation, high drilling speed, fewer drilling accidents, and low drilling costs. Therefore, they can meet the steerable drilling requirements of challenging and specialized wells, including extended reach wells, horizontal wells, highly deviated wells, branch wells, and three-dimensional multi-objective wells.
[0003] Existing rotary guide bearings are characterized by large diameters and tight fits, often requiring hammering to install them. This process involves significant resistance and difficulty in proper alignment. Using forced assembly or hammering methods can easily damage the bearing and its housing. Furthermore, assembling the bearing is time-consuming and labor-intensive, impacting assembly efficiency and effectiveness. Summary of the Invention

[0021] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.
[0022] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.
[0023] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1-8As shown, the rotary guide bearing assembly fixture for oil equipment includes a positioning and clamping assembly 1, a pressing assembly 2, and a bearing positioning assembly 3. The positioning and clamping assembly 1 includes a mounting base plate 101 and a positioning frame 105. A lower clamping seat 102 is installed on the upper rear part of the mounting base plate 101. A transition block 103 is provided on the upper right side of the lower clamping seat 102, and a positioning block 104 is provided on the upper left side of the lower clamping seat 102. The positioning frame 105 is U-shaped with its opening facing downwards. The lower part of the positioning frame 105 is connected to the transition block 103 and the positioning block 104 respectively by fixing pins. The positioning frame 105 has a threaded hole that runs vertically through the middle. The adjusting screw 106 is installed in the threaded hole. The lower end of the adjusting screw 106 is rotatably connected to a guide plate 107. The lower end of the guide plate 107 is equipped with an upper clamping seat 108. The upper clamping seat 108 and the lower clamping seat 102 are provided with clamping grooves with opposite openings. The upper front side of the positioning clamping assembly 1 is equipped with a top pressure assembly 2. The top pressure assembly 2 is equipped with a bearing positioning assembly 3 that can clamp the bearing. The top pressure assembly 2 can drive the bearing positioning assembly 3 to move back and forth.
[0024] Rotating the adjusting screw 106 moves the upper clamping seat 108 upward, locking the bearing spindle in the clamping groove between the upper clamping seat 108 and the lower clamping seat 102. Then, rotating the adjusting screw 106 in the opposite direction moves the upper clamping seat 108 downward, clamping the bearing spindle. The bearing is held by the bearing positioning assembly 3, and the bearing positioning assembly 2 pushes the bearing positioning assembly 3 to achieve top-pressure installation of the bearing. This ensures high stability of the bearing during top-pressure installation, resulting in high installation efficiency and quality, and avoiding damage to the bearing and spindle caused by knocking.
[0025] The assembly tooling for the rotary guide bearing of the above-mentioned oil equipment can be further optimized and / or improved according to actual needs: Example 2: As shown in the attached document Figure 3-4 As shown, both the lower clamping seat 102 and the upper clamping seat 108 are provided with V-shaped clamping grooves, and the bottom of the clamping grooves is provided with anti-slip teeth. By providing anti-slip teeth, the clamping effect of the lower clamping seat 102 and the upper clamping seat 108 is enhanced, and unstable clamping is avoided.
[0026] Example 3: As shown in the attached document Figure 4 As shown, the guide plate 107 has grooves at both its left and right ends, and the left and right ends of the guide plate 107 are slidably connected to the inner side of the positioning frame 105. The guide plate 107 limits the movement of the adjusting screw 106, keeping the upper clamping seat 108 moving stably up and down.
[0027] Example 4: As shown in the appendix Figure 3-4 As shown, a positioning plate 109 is rotatably mounted on the left side of the positioning frame 105, and the lower end of the positioning plate 109 is engaged with the lower clamping seat 102. The positioning plate 109 further fixes the positioning frame 105 and the lower clamping seat 102, and the engagement is convenient and quick.
[0028] Example 5: As shown in the attached document Figure 5-6 As shown, the top-pressure assembly 2 includes a loading plate 201 mounted on a mounting base plate 101 at the rear. Two bearing seats 202 are provided on the loading plate 201 at a distance from front to back. An adjusting screw 203 is installed between the two bearing seats 202. Guide rods 204 are installed on the loading plate 201 at the left and right sides corresponding to the adjusting screw 203. An adjusting block 205 is threaded onto the adjusting screw 203. The adjusting block 205 can move back and forth along the guide rod 204. A mounting seat 206 is installed on the upper side of the adjusting block 205. A servo motor 207 that is drivenly connected to the adjusting screw 203 is installed at the front end of the loading plate 201.
[0029] The servo motor 207 in the top pressure assembly component 2 drives and controls the control screw 203, so that the control block 205 can slide between the guide rods 204, and the bearing seat 206 can drive the bearing positioning component 3 to slide, so that the bearing is sleeved on the main shaft.
[0030] Example 6: As shown in the appendix Figure 7-8 As shown, the bearing positioning assembly 3 includes a transition plate 301 mounted on the mounting base 206. A positioning disk 302 is mounted on the transition plate 301. The positioning disk 302 has a through hole running through the center. Three sets of bearing clamping assemblies with the same structure are evenly distributed along the circumference of the positioning disk 302. The bearing clamping assembly includes an extension plate 303 integrally formed with the outer side of the positioning disk 302. A connecting plate 304 is mounted on the rear side of the extension plate 303. An electric hydraulic cylinder 305 is mounted on the connecting plate 304. A transition seat 306 is mounted on the rear side of the positioning disk 302 corresponding to the position of the extension plate 303. A fixing plate 307 is rotatably mounted on the transition seat 306. The fixing plate 307 is L-shaped. A connecting plate 308 is mounted on the rear side of the fixing plate 307. The extended end of the electric hydraulic cylinder 305 is hinged to the connecting plate 308.
[0031] By placing the bearing on the positioning plate 302, and then pushing the three sets of fixing plates 307 by the electric hydraulic cylinder 305, the fixing plates 307 position and fix the bearing placed on the positioning plate 302. After the fixing plates 307 fix the bearing, the bearing positioning assembly 3 is pushed by the top pressure assembly assembly 2 to realize the top pressure installation of the bearing.
[0032] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
