Description

Technical Field

[0001] This utility model relates to the field of oil drilling equipment testing technology, specifically a torque test bench for a mud pulse generator. Background Technology

[0002] The mud pulse generator is a key component in measurement while drilling (MWD) and logging while drilling (LWD) systems. It transmits downhole measurement data to the surface in real time by generating pressure pulses in the drilling mud. The mud pulse generator typically consists of a drive motor, transmission mechanism, and pulse valves, and its performance directly affects the reliability and accuracy of data transmission.

[0003] Currently, to ensure the working performance of the mud pulse generator, a torque tester is used to test the output torque of the mud pulse generator. By connecting the output end of the generator to the input end of the torque tester, the torque tester can convert the torsional force (torque) applied by the pulse generator into a measurable and displayable electrical signal during the test, and finally display the torque value in digital form on the instrument's display screen.

[0004] However, traditional torque testers suffer from cumbersome operation and low efficiency during use. When installing mud pulse generators, especially those of different diameters, operators must manually fix and align them with the tester's input shaft. Due to the lack of an effective adjustment mechanism, the mud pulse generator often requires repeated longitudinal adjustments to achieve precise alignment of the two shafts. This process relies on manual experience and external measuring tools, is time-consuming and labor-intensive, and severely impacts the convenience and efficiency of testing. Utility Model Content

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.

[0020] Example: Reference Figures 1-5 A torque testing bench for a mud pulse generator includes a torque tester 1 and a testing bench 2.

The first adjustment part is used to drive the two V-shaped clamps 5 to move closer and further apart. An anti-slip pad 8 is fixedly connected to the surface of the V-shaped clamps 5. The shape of the anti-slip pad 8 is adapted to the contour of the inner side of the V-shaped clamps 5 to improve the clamping and positioning effect. A second adjustment part is provided on the bracket 3. The second adjustment part is used to drive the adjustment box 4 to rise and fall.

[0021] Of course, in other embodiments, the first adjustment part includes a double-ended lead screw 51 rotatably connected to the adjustment box 4. The threads on both sides of the outer wall of the double-ended lead screw 51 are designed in opposite directions. A moving groove 53 is provided through the adjustment box 4. At least two drive plates 52 are slidably connected in the moving groove 53. The two drive plates 52 are respectively threaded to both sides of the outer wall of the double-ended lead screw 51. A V-shaped clamp 5 is fixedly connected to the drive plate 52. A telescopic dustproof curtain 9 is provided in the moving groove 53. When the drive plate 52 slides along the moving groove 53, the telescopic dustproof curtain 9 will extend and retract with the drive plate 52, which can block the moving groove 53 and prevent contamination of the inside of the adjustment box 4. The adjustment box 4 is provided with a drive component for driving the double-ended lead screw 51 to rotate. The drive component includes a worm gear 54 fixedly connected to the double-ended lead screw 51. A worm 55 that meshes with the worm gear 54 is rotatably connected to the adjustment box 4. One end of the worm 55 is fixedly connected to a first crank handle 56.

[0022] Specifically, during use, by rotating the first crank 56, the worm 55, worm wheel 54 and double-ended lead screw 51 are driven to rotate. Under the action of the opposite threads, the two drive plates 52 drive the two V-shaped clamps 5 to move closer or further apart, which can realize the rapid clamping and positioning of mud pulse generators of different diameters, so that their output shaft and the input shaft of the torque tester 1 are kept coplanar and parallel, improving the convenience and efficiency of the testing work.

[0023] The second adjustment part includes a lifting frame 6 fixedly connected to the adjustment box 4. A screw 61 is threadedly connected to the bracket 3. The screw 61 has a self-locking thread to prevent it from rotating due to external force. The bottom end of the screw 61 is rotatably connected to the lifting frame 6, and the top end of the screw 61 is fixedly connected to a second crank 62. The bracket 3 is provided with auxiliary control components for guiding and positioning the adjustment box 4. The auxiliary control components include guide blocks 7 fixedly connected to both sides of the adjustment box 4. Guide grooves 71 are opened on both sides of the inner wall of the bracket 3.

The stud 73 is slidably arranged in the sliding groove 72. A handwheel 74 is threadedly connected to the stud 73. A positioning ring 75 is fitted on the stud 73. The end face of the positioning ring 75 is provided with anti-slip texture, and the outer wall of the bracket 3 is a rough surface. The positioning ring 75 is fixedly connected to the handwheel 74. When the handwheel 74 is rotated, the positioning ring 75 abuts against the outer wall of the bracket 3.

[0024] Specifically, in use, by rotating the second crank 62, the screw 61 is driven to rotate. Under the action of the thread, the screw 61 drives the lifting frame 6, the adjusting box 4, the V-shaped clamp 5, and the mud pulse generator to move upward or downward. This enables the adjustment and positioning of the longitudinal position of mud pulse generators of different diameters, allowing its output shaft to be quickly and accurately aligned with the input shaft of the torque tester 1, saving time and effort and further improving the convenience and efficiency of the testing work. Furthermore, when the adjusting box 4 is raised or lowered, it also drives the guide block 7 to slide longitudinally along the guide groove 71, and the stud 73 slides along the guide groove 71. The groove 72 slides longitudinally. After the longitudinal position of the mud pulse generator is determined, the handwheel 74 can be threaded onto the stud 73, so that the positioning ring 75 abuts against the outer wall of the bracket 3. Through the setting of the guide block 7, stud 73, handwheel 74 and positioning ring 75, the adjustment box 4 and V-shaped clamp 5 can be guided, improving the stability of the longitudinal position adjustment process of the mud pulse generator. It can also provide locking positioning for the adjustment box 4 and V-shaped clamp 5, further preventing the screw 61 from rotating due to external force, and ensuring the stability of the mud pulse generator after adjustment and the reliability during the test process.

[0025] Finally, the testers fixedly connected the output shaft of the mud pulse generator to the input shaft of the torque tester 1 via a coupling, and then started the test. The torque tester 1 can convert the torsional force applied by the mud pulse generator into a measurable and displayable electrical signal, and finally display the torque value in digital form on the instrument's display screen. The testers then evaluated the test results.
