Description

Technical Field

[0001] This utility model relates to the technical field of turbine installation and adjustment tools, and more specifically, to a centering bracket for a turbine gear ring coupling. Background Technology

[0002] When installing a steam turbine / gas turbine rotor with a gear ring, the center of the two gears needs to be adjusted during the installation process. The previous adjustment method was to make a measuring bracket, which was fixed by bolts passing through the entire coupling. Through multiple measurements and adjustments, the centers of the two gears were aligned before installation and fixation.

[0003] Existing centering adjustment methods have several drawbacks: They use coupling bolts or other types of large bolts to ensure stability. Both coupling bolts and other bolts require high tightening torques, making installation and disassembly inconvenient. The bracket requires large washers to mate with the bolts, ensuring stable installation, which is relatively complex to manufacture. Utility Model Content

[0033] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0034] See Figure 1 As shown, this embodiment provides a centering bracket for a turbine gear ring coupling, including a fixed support 100, an extension 200, and a measuring element 300. The fixed support 100 has a reference seat 110 that abuts against the gear ring 400. A locking element 120 is provided at one end of the fixed support 100 opposite to the reference seat 110, and the locking direction of the locking element 120 is perpendicular to the reference seat 110. The extension 200 is connected to the fixed support 100, and the measuring element 300, which can measure the opening and height difference of the coupled rotor 500, is installed on the extension 200.

[0035] Specifically, during use, the operator first fixes the fixed support 100 onto the gear ring 400. Specifically, the operator abuts the reference seat 110 of the fixed support 100 against the end face of the gear ring 400, and then uses the locking member 120 to abut against the other end face of the gear ring 400, thereby fixing the fixed support 100 onto the gear ring 400. Then, the measuring member 300 is installed on the extension seat 200. At this time, the reference for the horizontal and vertical directions measured by the measuring member 300 on the extension seat 200 is the end face of the gear ring 400. Therefore, the rotor of the coupling can be measured accurately and conveniently. The operator can adjust the position of the coupling rotor 500 according to the measurement.

[0036] The fixed support 100 is n-shaped. The reference base 110 and the locking member 120 are respectively disposed on both sides of the fixed support 100 structure. Under the action of the locking member 120, the reference base 110 can be tightly abutted against the side wall of the gear ring 400, so that the fixed support 100 is mounted on the gear ring 400. At the same time, the extension seat 200 is fixed on the fixed support 100. The extension seat 200 is set perpendicular to the fixed support 100, so that the reference of the extension seat 200 is based on the gear ring 400. This allows the measuring member 300 to perform direct measurement and the measurement data to be accurate.

[0037] It should be noted that coupling opening alignment refers to the process of determining the installation position of each coupling by measuring and calculating the opening of the coupling end faces during the installation of mechanical equipment. Coupling opening alignment is a crucial step in ensuring the normal operation and extending the service life of mechanical equipment, and it directly affects the smoothness of equipment operation, vibration, and noise levels.

[0038] See Figure 1 As shown, in the optional embodiment, the locking member 120 includes a locking bolt 121, and the fixed support 100 has a threaded hole adapted to the locking bolt 121. One end of the locking bolt 121 can abut against the end face of the gear ring 400.

[0039] The locking bolt 121 is provided with a locking nut 122, which is sleeved on the locking bolt 121 and can abut against the fixed support 100.

[0040] The locking nut 122 is located between the fixed support 100 and the gear ring 400.

[0041] Specifically, when the worker locks the fixed support 100 onto the gear ring 400, the worker screws the locking bolt 121 into the threaded hole of the fixed support 100. Then, after the locking bolt 121 abuts against the end face of the gear ring 400, the worker tightens the locking nut 122 sleeved on the locking bolt 121. The locking nut 122 is located between the fixed support 100 and the gear ring 400. The locking nut 122 can tightly abut against the fixed support 100, thereby locking the locking bolt 121 and preventing the locking bolt 121 from loosening from the fixed support 100 during subsequent use, thus ensuring the stability of the position of the fixed support 100 and the extension seat 200.

[0042] See Figure 1 As shown, in the optional embodiment, the extension seat 200 is L-shaped.

[0043] The extension seat 200 includes a long rod seat 210 and a short rod seat 220; one end of the long rod seat 210 is fixedly connected to the fixed support 100, and the other end is fixedly connected to the short rod seat 220.

[0044] Among them, the long rod seat 210 is perpendicular to the fixed support 100, and the short rod seat 220 is perpendicular to the long rod seat 210.

[0045] See Figure 1 As shown, in an optional embodiment, the measuring component 300 includes a height difference measuring dial indicator 310, which is mounted on a long rod base 210.

[0046] The measuring component 300 also includes an opening measuring dial indicator 320, which is mounted on the long rod base 210.

[0047] Specifically, the height difference measuring dial indicator 310 and the opening measuring dial indicator 320 are respectively mounted on the long rod seat 210 and the short rod seat 220 of the extension seat 200, so that the height difference measuring dial indicator 310 and the opening measuring dial indicator 320 are perpendicular to each other. This allows the height difference measuring dial indicator 310 to measure the height difference between the gear rotor 500 and the gear ring 400, and the opening measuring dial indicator 320 to measure the opening of the end face of the gear rotor 500, so that the staff can easily make adjustments.

[0048] The height difference measuring dial gauge 310 and the mouth opening measuring dial gauge 320 are both mounted on the extension seat 200 by locking screws.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
