DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] Referring to Figures 1-4 as shown, the present utility model provides a technical solution: a quickly adjustable, detachable and assembled swing sensor device for a water turbine guide bearing, including a mounting cylinder 1. A first plug 8 and a second plug 9 are respectively and fixedly installed at both ends of the mounting cylinder 1. A moving frame 2 is slidably connected inside the mounting cylinder 1. A fixing pin 15 is slidably connected to the outside of the moving frame 2. Two screw rods 6 are slidably inserted through the inside of the fixing pin 15. Nuts 7 are threadedly connected to the outside of the screw rods 6. Four mounting rings 4 are evenly and fixedly connected to the outside of the fixing pin 15 in pairs. A swing sensor body 3 is slidably installed inside two mounting rings 4.
[0024] The following specifically describes its overall specific settings and functions.
[0025] In this embodiment: Two bolts 5 are internally threadedly connected to the mounting ring 4. A lead screw 29 is rotatably connected inside the first plug 8 and the second plug 9. The lead screw 29 is internally threadedly connected to the inside of the moving frame 2. An internal hexagonal block 22 is fixedly connected to the end side of the lead screw 29. A number of card slots 20 are evenly formed on the side wall of the lead screw 29. A rectangular block 16 is fixedly connected to the surface of the first plug 8. A card frame 17 is slidably connected inside the rectangular block 16. The size of the card frame 17 is adapted to the size of the card slot 20. A first mounting seat 11 and a second mounting seat 12 are fixedly connected to the lower side of the mounting cylinder 1. Mounting holes are formed on the surfaces of the first mounting seat 11 and the second mounting seat 12. The setting of the detachable swing sensor device facilitates the flexibility of using the swing sensor device on the equipment. The lead screw 29 that can be twisted and locked avoids the phenomenon that the lead screw 29 becomes loose when the equipment vibrates during use, which in turn causes the position of the swing sensor body 3 to deviate. To a certain extent, the accuracy of the measurement result of the swing sensor body 3 is improved.
[0026] Specifically, a spring 19 is fixedly connected between the card frame 17 and the rectangular block 16. The card frame 17 is inserted into the inner side of the corresponding card slot 20 on the side wall of the lead screw 29 under the action of the elastic force of the spring 19. A support frame 18 is slidably connected inside the card frame 17. The cross section of the support frame 18 is in the shape of an "L". Slide the support frame 18 to the position facing the rectangular block 16. At this time, release the card frame 17 to realize the temporary support work of the lifted card frame 17. At this time, the lead screw 29 can be freed from the restraint of the card frame 17 stuck inside the card slot 20 and twist flexibly.
[0027] A number of scale lines 13 are evenly arranged on the side wall of the mounting cylinder 1. An indicating arrow 14 is arranged on the surface of the moving frame 2. By setting the indicating arrow 14 to point to the scale line 13, the accuracy of adjusting the position of the swing sensor body 3 is improved. A screw ring 21 is fixedly connected to the surface of the second plug 9. A threaded cover 10 is threadedly connected to the outside of the screw ring 21. A rotating pin 23 is rotatably connected to the inside of the threaded cover 10. A reserved hole 24 is formed on the surface of the rotating pin 23. A hexagonal prism bar 25 is inserted into the inside of the reserved hole 24 and the inner hexagonal block 22. The size of the hexagonal prism bar 25 is adapted to the size of the reserved hole 24. A rotating bar 26 is rotatably connected to the surface of the hexagonal prism bar 25. A fixing rod 27 is fixedly connected to the surface of the rotating bar 26. A rotating cylinder 28 is rotatably connected to the side wall of the fixing rod 27. After rotating the threaded cover 10 to the outside of the screw ring 21, insert the hexagonal prism bar 25 into the inside of the reserved hole 24 and the inner hexagonal block 22 in sequence. At this time, the twisting work of the hexagonal prism bar 25 can be realized by controlling the rotating cylinder 28, the fixing rod 27 and the rotating bar 26. The hexagonal prism bar 25 can realize the driving rotation work of the inner hexagonal block 22, and further realize the twisting work of the lead screw 29 inside the first plug 8 and the second plug 9.
[0028] Working principle: When it is necessary to adjust the position of the swing sensor, first slide the clamping frame 17 inside the rectangular block 16. After pulling out the clamping frame 17 from the inside of the clamping groove 20, the support frame 18 inside the clamping frame 17 can be slid, and the support frame 18 is slid to a position facing the rectangular block 16. At this time, release the clamping frame 17, and the temporary support work for the lifted clamping frame 17 can be realized. At this time, the lead screw 29 can be disengaged from the restraint of the clamping frame 17 stuck inside the clamping groove 20 and twist flexibly. After rotating the threaded cover 10 to the outside of the screw ring 21, insert the hexagonal prism bar 25 into the inside of the reserved hole 24 and the inner hexagonal angular block 22 in sequence. At this time, the twisting work of the hexagonal prism bar 25 can be realized by controlling the rotating cylinder 28, the fixed rod 27 and the rotating bar 26. The hexagonal prism bar 25 can realize the driving rotation work of the inner hexagonal angular block 22, and then the twisting work of the lead screw 29 inside the first plug 8 and the second plug 9 can be realized. At this time, the driving work of the moving frame 2 in the horizontal direction can be realized, and further the adjustment work of the horizontal direction of the position of the fixed pin 15 and the swing sensor body 3 can be realized. By setting the indicating arrow 14 pointing to the scale line 13, the accuracy of the position adjustment of the swing sensor body 3 is improved. After the adjustment is completed, the hexagonal prism bar 25 can be withdrawn, and then the support frame 18 inside the clamping frame 17 is slid out from the rectangular block 16. At this time, the clamping frame 17 will be inserted into the inside of the corresponding clamping groove 20 on the side wall of the lead screw 29 under the action of the elastic force of the spring 19, and the locking work of the position of the twisted lead screw 29 can be realized, which can avoid the phenomenon that the lead screw 29 twists due to equipment vibration in the later stage, and then easily leads to the deviation of the position of the swing sensor body 3, improving the accuracy of the subsequent use of the swing sensor body 3. By setting the bolts 5 inside the mounting ring 4, the flexible disassembly and assembly work of the swing sensor body 3 can be realized, facilitating the regular maintenance work of the swing sensor body 3. The fixed pin 15 can be installed on the moving frame 2 by means of the connection between the screw 6 and the nut 7, and the flexible adjustment of the use height of the swing sensor body 3 can be realized by moving up and down. By setting the first mounting seat 11, the second mounting seat 12 and the mounting holes on the mounting seats, the flexible disassembly and assembly work of the mounting cylinder 1 on the equipment is facilitated, improving the flexibility of the installation and use of the swing sensor body 3. By setting the above structure, a detachable swing sensor device is set, facilitating the flexibility of the use of the swing sensor device on the equipment. By setting the lead screw 29 that can be locked after twisting, the phenomenon that the lead screw 29 loosens due to equipment vibration during use and then leads to the deviation of the position of the swing sensor body 3 is avoided, improving the accuracy of the measurement result of the swing sensor body 3 to a certain extent.
