Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine bracket adjustment, in particular to a diesel engine bracket adjustment device and a diesel engine bracket. Background Art

[0002] In the prior art, the exciter of the emergency diesel generator set is prone to the defect of high vibration. During the full-power re-identification of the diesel engine, the vibration is greater than the standard value of 18 mm / s. After the operator conducts an online vibration spectrum analysis, it is concluded that there is no abnormal wear on the diesel engine and the generator. The direct reason for the high vibration is the uneven force on the diesel engine bracket, resulting in the vibration exceeding the standard. Multiple grid-connected online adjustments are required. The diesel engine bracket itself is heavy (about 30 kg), the position is narrow, the bottom layer is 1.6 meters from the ground, and the upper layer is 2.2 meters from the ground. The existing adjustment method is for two people to lift the lower layer of the bracket together, and one person stands on a folding ladder to tighten the connecting bolts. The on-site operation is very unstable. The operator cannot continue to hold on after applying force for five minutes. Moreover, working beside the rotating unit for a long time poses a potential risk of mechanical injury. This work needs to be carried out repeatedly to adjust the vibration repeatedly.

[0003] Based on this defect analysis, the relative position of the diesel engine bracket affects the force on the exciter by the diesel engine bracket. During the operation of the diesel engine, there are vibrations in all directions.

It should be noted that the connecting hole can also be provided on the bracket of the connecting flange, as long as it can ensure that when adjusting the first nut or the third nut, the connecting flange can move correspondingly. Such an arrangement can adjust the relative position between the connecting flange and the diesel engine bracket. Because the actual distance to be adjusted is very small, and the connecting flange and the diesel engine bracket are relatively heavy, there will be no displacement of the third nut and the first nut, ensuring the stability during the adjustment process.

[0040] To optimize the above technical solution, the fixing member includes a U-shaped groove 300 and an extension plate 301. The first groove wall and the second groove wall of the U-shaped groove 300 are respectively arranged at the top and bottom of the rib plate 101, and the groove bottom of the U-shaped groove 300 is arranged in the thickness direction of the rib plate 101, so that the U-shaped groove 300 is clamped in the thickness direction of the rib plate 101. The extension plate 301 and the first groove wall are integrally designed, and the extension plate 301 is tightly abutted against the top of the rib plate 101. Specifically, the extension plate 301 functions as a positioning spacer, and the U-shaped groove 300 is used to connect the fixing member and the rib plate 101. During use, the opening of the U-shaped groove 300 clamps the rib plate 101 from the thickness direction of the rib plate 101 to achieve preliminary fixation. The extension plate 301 is arranged at the bottom of the adjusting member for positioning and supporting the adjusting member. During the adjustment process, the total height of the adjusting member changes to lift or lower the connecting flange, so as to achieve the purpose of adjusting the distance between the connecting flange and the diesel engine bracket. It should be noted that the fixing member and the adjusting member are of a split structure. Such an arrangement can achieve the detachable connection between the fixing member and the rib plate 101, which is convenient for maintaining and replacing the fixing member and improves the service life of the second adjustment assembly 200.

[0041] To optimize the above technical solution, the adjusting member includes an adjusting support plate 302, a fourth bolt 304 and a fourth nut 305.

The extension plate 301 is arranged at the bottom of the adjusting support plate 302, and the fourth bolt 304 passes through the through-threaded hole 303 and abuts against the extension plate 301. Specifically, the number of the through-threaded holes 303 is two or more and is evenly arranged around the connecting flange. The number of the fourth bolts 304 and the fourth nuts 305 corresponds to the number of the through-threaded holes 303. During use, the fourth bolt 304 passes through the through-threaded hole 303 and abuts against the extension plate 301, and the fourth nut 305 cooperates with the fourth bolt 304. The operator rotates the fourth bolt 304 to make the adjusting support plate 302 connected to the fourth bolt 304 move up or down to adjust the position of the connecting flange, so as to achieve the purpose of adjusting the relative position between the diesel engine bracket and the connecting flange and finding an optimal position to reduce the exciter vibration to an excellent value.

[0042] To optimize the above technical solution, two counterbores 306 are provided on the extension plate 301, and the counterbores 306 abut against the fourth bolts 304. During use, the fourth bolts 304 pass through the through-threaded holes 303 and abut against the counterbores 306. When the operator rotates the fourth bolts 304, the counterbores 306 will limit the fourth bolts 304, thereby preventing the fourth bolts 304 from shifting and ensuring the adjustment accuracy of the second adjustment assembly 200.

[0043] To optimize the above technical solution, a clamping threaded hole is provided at the bottom of the second groove wall. The fixing member further includes a fifth bolt and a fifth nut 307, which are matched with each other. The fifth bolt passes through the clamping threaded hole to abut against the rib plate 101. During use, when the opening of the U-shaped groove 300 clamps the rib plate 101 from the thickness direction of the rib plate 101 to achieve the preliminary fixation of the fixing member and the rib plate 101, the operator passes the fifth bolt through the clamping threaded hole and adjusts the position of the fifth bolt so that it abuts against the bottom of the rib plate 101. Such an arrangement enables the fixing member to stably support the connecting flange, and maintain balance and improve the adjustment accuracy when adjusting the relative position between the connecting flange and the diesel engine bracket.
