Technical Field
[0001] This utility model belongs to the field of measuring tool technology, specifically a pressure balance piston position measuring tool. Background Technology
[0002] With the advancement of drilling technology and the increase in drilling depth, the requirements for the pressure resistance of drilling instruments are becoming increasingly stringent, and pressure balancing devices are being used more and more frequently. In practical applications, it is necessary to check whether the position of the piston in the pressure balancing device meets the requirements after each assembly. In the traditional way, it is cumbersome and inaccurate to estimate the piston position using simple means. Using a laser rangefinder with a steering head can quickly and conveniently measure the piston position.
[0003] When using a laser rangefinder, insert the steering head into the hole on the surface of the pressure balancing device. The laser rangefinder emits a laser through the laser sensor and is steered by the steering head so that the laser shines on the piston surface. The sensor then receives the reflected light from the laser reaching the object's surface and calculates the time taken for the laser to be emitted and the reflected light to return to measure the distance.
[0004] However, in actual use, after inserting one end of the steering head into the hole on the surface of the pressure balancing device, it is impossible to accurately observe the orientation of the steering head. Furthermore, the steering head is prone to accidental rotation during the measurement process, causing the laser position to deviate and affecting the accuracy of the measurement results.

[0007] As a further embodiment of this utility model: the diameter of the round rod is slightly smaller than the inner diameter of the spring, and the round rod is located inside the spring.
[0008] As a further embodiment of this utility model: a plurality of protrusions are fixedly connected to the outer surface of the ring, and the protrusions are distributed circumferentially on the outer surface of the ring.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a pressure balancing piston position measuring tool, including a body 1, a laser head 4 at one end of the body 1, a control button 5 on one side of the body 1, a display screen 6 at the top of the body 1, a charging slot on one side of the body 1, a steering head 7 rotatably connected to the outer surface of the body 1 near the laser head 4, a groove head 8 fixedly connected to the bottom end of the steering head 7, an inclined groove inside the groove head 8, and a silver-plated coating on the surface of the groove head 8. A convenient device 2 is provided on the outer surface of the body 1, the convenient device 2 including a ring 21, the inner wall of the ring 21 being rotatably connected to the outer surface of the body 1, and one side of the ring 21 being fixedly connected to... A rectangular rod 22 is attached, with one end of the rectangular rod 22 away from the ring 21 fixedly connected to the top of the steering head 7. A protruding rod 23 is fixedly connected to one side of the ring 21, with the protruding rod 23 facing the same direction as the inclined groove on the outer surface of the groove head 8. A rectangular block 24 is fixedly connected to the side of the ring 21 away from the protruding rod 23, and an L-shaped block 25 is fixedly connected to one side of the rectangular block 24. A round rod 26 is slidably connected to the inner walls of the L-shaped block 25 and the rectangular block 24. A pressure block 27 is fixedly connected to one end of the round rod 26, and a spring 28 is provided on the outer surface of the round rod 26. The two ends of the spring 28 are fixedly connected to one side of the round rod 26 and one side of the L-shaped block 25, respectively. By setting the protruding rod 23, when using the measuring tool... Insert the groove 8 at the bottom of the steering head 7 into the hole on the outer surface of the pressure balancing device. Pull the round rod 26 to control it to move away from the body 1 along the inner wall of the rectangular block 24 and the L-shaped block 25, compressing the spring 28. Then push the ring 21 to drive the steering head 7 and the groove 8 to rotate via the rectangular rod 22. Observe the orientation of the groove 8 through the protruding rod 23. After rotating to the specified angle, release the round rod 26. The spring 28 will push the round rod 26 to move, pressing the pressure block 27 at one end of the round rod 26 onto the outer surface of the body 1, limiting the angle between the ring 21 and the steering head 7 and the body 1. Then, control the laser sensor inside the body 1 via the control button 5 to emit laser light. The laser is irradiated onto the silver-plated inclined groove inside the groove head 8. The laser is deflected by the inclined groove and then directed vertically toward the piston surface inside the pressure balancing device. The laser sensor receives the reflected light and measures the distance to the piston based on the time of laser emission and the arrival of the reflected light, which is then displayed on the display screen 6. By setting up the convenient device 2, the steering head 7 can be more easily controlled to turn by pushing the ring 21. The position of the groove head 8 can be observed by the orientation of the protrusion 23. Pressing one side of the pressure block 27 against the outer surface of the body 1 can fix the angle between the ring 21 and the steering head 7, minimizing the possibility of the steering head 7 rotating during the measurement process and affecting the accuracy of the test results.
[0024] Specifically, such as Figure 2-4As shown, the diameter of the round rod 26 is slightly smaller than the inner diameter of the spring 28. The round rod 26 is located inside the spring 28. When the round rod 26 is pulled to move and the spring 28 is deformed, the spring 28 will move outside the round rod 26. The round rod 26 can reinforce the internal shape of the spring 28 and prevent the spring 28 from twisting laterally, which would affect normal use. Several protrusions 29 are fixedly connected to the outer surface of the ring 21. The protrusions 29 are distributed circumferentially on the outer surface of the ring 21. By pressing the protrusions 29 on the outer surface of the ring 21 with your hand, you can more easily push the ring 21 to rotate and it is less likely to slip.
[0025] Specifically, such as Figure 2-4 As shown, a number of protrusions 210 are fixedly connected to one side of the pressure block 27. The protrusions 210 are rubber strips made of rubber. By pressing the side of the pressure block 27 with the rubber protrusions 210 against the outer surface of the body 1, the position between the ring 21 and the body 1 is fixed more stably and less prone to slippage.
[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a protective device 3 is provided on the outer surface of the device 1 near the control button 5. The protective device 3 includes a cover plate 34, with two L-shaped rods 33 fixedly connected to one side of the cover plate 34. Two L-shaped grooves 31 are formed on one side of the device 1, and a rectangular groove 32 is formed on one side of the device 1. The two L-shaped rods 33 slide on the inner walls of the two L-shaped grooves 31 respectively, and the cover plate 34 slides on the inner wall of the rectangular groove 32. A groove block 35 is fixedly connected to one side of the cover plate 34, and an insert block is fixedly connected to one side of the groove block 35. The device has a slot 37. When not using measuring tools, the cover plate 34 can be pushed to control the cover plate 34 to slide on the inner wall of the L-shaped groove 31 via two L-shaped rods 33. The position of the cover plate 34 is adjusted so that the cover plate 34 covers the outside of the control button 5. The insertion rod 36 on one side of the slot block 35 is inserted into the slot 37. The cover plate 34 covers one side of the control button 5, which avoids the control button 5 being pressed when carrying measuring tools, which could cause the laser sensor to operate unexpectedly, resulting in wasted power resources and insufficient power when using measuring tools.
[0027] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, a positioning block 38 is fixedly connected to one end of the insertion rod 36. The positioning block 38 is made of rubber and its width is slightly larger than that of the insertion rod 36. When the insertion rod 36 is inserted into the slot 37, the rubber positioning block 38 will fit tightly against the inner wall of the slot 37, further restricting the position of the insertion rod 36 inside the slot 37 and the position of the cover plate 34 on the side of the control button 5, so as to avoid the cover plate 34 from sliding accidentally. Two grooves are opened on the outer surface of the slot block 35. The two grooves are located on the left and right sides of the slot block 35 respectively. Pinching the two grooves on the outer surface of the slot block 35 can more easily push the slot block 35 to control the movement of the cover plate 34.
[0028] The working principle of this utility model is as follows: S1. When using the measuring tool, insert the groove head 8 at the bottom of the steering head 7 into the hole on the outer surface of the pressure balancing device. Pull the round rod 26 to control the round rod 26 to move away from the body 1 on the inner wall of the rectangular block 24 and the L-shaped block 25 and compress the spring 28. Then push the ring 21 to drive the steering head 7 and the groove head 8 to rotate through the rectangular rod 22. Observe the orientation of the groove head 8 through the protruding rod 23. After rotating to the specified angle, release the round rod 26 and push the round rod 26 to move through the spring 28 to press the pressure block 27 at one end of the round rod 26 onto the outer surface of the body 1, limiting the angle between the ring 21 and the steering head 7 and the body 1. Then, control the laser sensor inside the control body 1 to emit a laser through the control button 5. Irradiate the silver-plated inclined groove inside the groove head 8. The laser is deflected through the inclined groove and then vertically shot to the piston surface inside the pressure balancing device. The laser sensor receives the arrival of the reflected light. Measure the distance of the piston based on the time of laser emission and the arrival of the reflected light and display it on the display screen 6.
[0029] S2. When not using measuring tools, the cover plate 34 can be pushed to control the cover plate 34 to slide on the inner wall of the L-shaped groove 31 via two L-shaped rods 33. The position of the cover plate 34 is adjusted so that the cover plate 34 covers the outside of the control button 5, and the insertion rod 36 on one side of the groove block 35 is inserted into the slot 37. The cover plate 34 covers one side of the control button 5, so as to avoid the control button 5 being pressed when carrying measuring tools, which may cause the laser sensor to operate unexpectedly.
