Abstract
Description
Technical Field
[0001] This utility model relates to the field of meter holder technology, and in particular to a fixed meter holder for aligning the back wheel of a steam-driven feedwater pump. Background Technology
[0002] Traditional dial indicator stands rely on magnets to fix one end of the stand. While this facilitates position adjustment, over time, the hollow connecting rod of the magnetic stand, secured by connectors, becomes unstable. Because the same measuring point must be in the same position during measurement, the dial indicator itself has weight, leading to inconsistent measuring point positions and the left and right dial indicators not being on the same horizontal plane. This significantly reduces the stability of the measurement results. Furthermore, when multiple such stands are used simultaneously in a limited space, the ability to move the stands makes adjustments extremely cumbersome, requiring careful handling to avoid touching or altering the position of other stands.

Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.
[0025] Example 1, referring to Figures 1-4 This embodiment provides a fixed bracket for centering the back wheel of a steam-driven feedwater pump, including:
[0026] Support assembly 1 includes a support frame 11, a dial indicator rod 15 connected to the side of the support frame 11, a lower dial indicator hole 14 provided on the surface of the dial indicator rod 15, a support rod 17 connected to one end of the support frame 11, and a fixing hole 12 provided on the surface of the support rod 17; and,
[0027] The lower locking post 2 is provided on the surface of the lower hole 14; and,
[0028] The fixing component 3 includes a bolt 31 and a lock nut 32 connected to the surface of the bolt 31.
[0029] Usage: Install the dial indicator in the lower dial hole 14, fix the dial indicator in the lower dial hole 14 by the lower locking pin 2, insert the bolt 31 into the hole of the fixed end, fix the support rod 17 to the surface of the fixed end by the locking nut 32, and find the center of the backrest wheel by moving the two dial indicators on the surface of the backrest wheel.
[0030] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention, which differs from the previous embodiment in that it also includes,
[0031] A locking hole 13 is provided on the side of the dial rod 15. The lower locking pin 2 is connected to the locking hole 13 by a threaded rotation. The locking hole 13 is connected to the lower dial hole 14.
[0032] The locking hole 13 has a thread inside, which engages with the thread on the surface of the lower locking pin 2, so that the lower locking pin 2 can move inside the locking hole 13 by rotation, pressing the dial indicator inside the lower gauge hole 14, thereby fixing the dial indicator in the lower gauge hole 14.
[0033] Bolt 31 is located inside fixing hole 12, and mounting hole 16 is provided on the surface of support frame 11.
[0034] Bolt 31 is set in the fixing hole 12. The support rod 17 is fixed in the hole of the fixing end by bolt 31 and fixed on the surface of the fixing end, thus completing the fixing of the support assembly. At the same time, the support frame 11 is aligned with the center position of the backrest wheel. The dial indicator fixed inside the lower dial hole 14 and the upper dial hole 46 is used to achieve precise centering.
[0035] The mounting hole 16 is internally connected to a lifting component 4, which includes a screw 43. The surface of the screw 43 is rotatably connected to an upper nut 42 and a lower nut 44 via threads.
[0036] The upper nut 42 and the lower nut 44 are set on the surface of the screw 43. By rotating the position of the upper nut 42 and the lower nut 44, the part of the screw 43 located in the mounting hole 16 is changed, thereby adjusting the height of the mounting plate 47 so that the dial indicator inside the upper dial hole 46 can be set on the outer edge of the backrest wheel, thereby achieving the centering of the backrest wheel.
[0037] One end of the screw 43 is fixed with a lifting rod 41, and the other end of the lifting rod 41 is fixed with a mounting plate 47.
[0038] Mounting plate 47 is positioned at the highest point of lifting rod 41, thereby allowing the dial indicator inside upper gauge hole 46 to be positioned at a higher level for measuring the outer edge of backrest wheel.
[0039] The surface of the mounting plate 47 is provided with an upper surface hole 46, and the side of the mounting plate 47 is connected to an upper locking post 45 by a threaded rotation.
[0040] The upper locking pin 45 is rotatably connected to the mounting plate 47 via a thread on its surface. Rotating the upper locking pin 45 can fix the dial indicator inside the upper dial hole 46.
[0041] The upper nut 42 and the lower nut 44 are respectively located at both ends of the support frame 11.
[0042] The upper nut 42 and the lower nut 44 move on the surface of the screw 43 through the threads on their surfaces, thereby pressing the support frame 11 from both ends and fixing the screw 43 inside the mounting hole 16.
[0043] Usage: Insert the dial indicator into the lower dial hole 14, align the lower locking pin 2 with the locking hole 13, rotate the lower locking pin 2, and the lower locking pin 2 moves inside the locking hole 13 through the surface thread. The lower locking pin 2 presses against the dial indicator, fixing the dial indicator inside the lower dial hole 14. Insert the dial indicator into the upper dial hole 46, rotate the upper locking pin 45 to press against the dial indicator, and the dial indicator is fixed inside the upper dial hole 46. Rotate the upper nut 42 and the lower nut 44 to move the upper nut 42 and the lower nut 44 away from the support frame 11, adjust the position of the lifting rod 41, and thus adjust the height of the mounting plate 47. After adjustment, rotate the upper nut 42 and the lower nut 44 to press against the surface of the support frame 11, completing the fixation of the height of the mounting plate 47. Use one dial indicator in the upper dial hole 46 and two dial indicators in the lower dial hole 14 to center the backrest wheels.
[0044] Example 3, referring to Figures 1-4 This is the third embodiment of the present invention, which differs from the previous embodiment in that it also includes,
[0045] A sleeve 33 and a positioning plate 34 are fitted onto the surface of the bolt 31, with one end of the sleeve 33 and the positioning plate 34 in contact.
[0046] The sleeve 33 can increase the outer diameter of the bolt 31, making the range of motion of the bolt after it is inserted into the hole at the fixed end smaller, thereby making the support rod 17 more stable.
[0047] Locking nut 32 and sleeve 33 are respectively installed at both ends of support rod 17.
[0048] The locking nut 32 can press the support rod 17 against the surface of the sleeve 33 to prevent the support rod 17 from moving.
[0049] The positioning plate 34 is located at the bottom of the sleeve 33.
[0050] The positioning plate 34 can fit against the surface of the fixed end, thereby increasing the contact area and further stabilizing the support rod 17.
[0051] Usage process: Place the positioning plate 34 on the surface of the screw 43, then place the sleeve 33 on the surface of the screw 43. Insert the bolt 31, which is equipped with the positioning plate 34 and the sleeve 33, into the hole at the fixed end. Move the support rod 17 so that the fixing hole 12 is aligned with the bolt 31. Insert the bolt 31 into the fixing hole 12. Fix the bolt 31 to the surface of the support rod 17 by tightening the lock nut 32 to ensure that the support rod 17 is stably fixed on the fixed end.
[0052] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
