[0028] As shown in Figure 1 The present embodiment provides a ship knuckle bearing lifting deck ear plate boring method, which comprises the following steps:

[0029] Step one: the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 are arranged correspondingly in front and back, and the hole centers of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 are adjusted to be on the same straight line;

[0030] Step two: the pile leg ear plate 3 is installed in the middle of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2, and the hole center of the pile leg ear plate 3 is adjusted to be on the same straight line with the hole centers of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2;

[0031] Step three: the knuckle bearing 4 is installed on the pile leg ear plate 3 through the adjusting mechanism, the relative position of the knuckle bearing 4 and the pile leg ear plate 3 is adjusted through the adjusting mechanism, so that the hole center point of the knuckle bearing 4 corresponds to the hole center of the pile leg ear plate 3, and then the hole center point of the knuckle bearing 4 is on the same straight line with the hole centers of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2;

[0032] Step four: after the hole center adjustment is completed, the boring bar 8 and the boring cutter 9 are used to bore the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 respectively;

[0033] Step five: after boring, pull out the boring bar 8, install the dummy shaft and the limiting sleeve in the knuckle bearing 4, put the pile leg into the middle of the lifting deck, use the connecting shaft to push the dummy shaft from the side, so that the connecting shaft is connected together through the center of the front and rear lifting deck ear plates 2 and the knuckle bearing 4.

[0034] Based on the above scheme, because the knuckle bearing 4 of the ship special equipment pile leg is installed, because of the rolling characteristics of the knuckle bearing 4, the center point of the knuckle bearing 4 cannot be fixed, so the adjustment and fixation of the knuckle bearing 4 are realized through the adjusting mechanism. First, the position of the knuckle bearing 4 is adjusted through the adjusting mechanism, so that the hole centers of the knuckle bearing 4 and the pile leg ear plate 3 are consistent in the vertical direction. Simply put, the horizontal coordinate point of the hole center of the knuckle bearing 4 is the same as that of the pile leg ear plate 3. After the position of the knuckle bearing 4 is adjusted, the position of the knuckle bearing 4 can be further fixed through the adjusting mechanism, so that the knuckle bearing 4 will not deviate and will not roll. Before adjusting the knuckle bearing 4, the positions of the front and rear lifting deck ear plates 1 and 2 need to be adjusted and fixed, and the hole centers of the front and rear lifting deck ear plates 1 and 2 need to be ensured to be on the same straight line. Then, the position of the pile leg ear plate 3 is adjusted so that the hole center of the pile leg ear plate 3 is also on the straight line. As long as the position of the knuckle bearing 4 on the pile leg ear plate 3 is adjusted and fixed, the hole center of the knuckle bearing 4 can also be ensured to be on the straight line. At this time, the accurate boring operation can be directly started, and the boring can be completed at one time, effectively improving the work efficiency. After the boring is completed, the connecting shaft can be accurately installed in place, avoiding rework.

[0035] Further, in order to effectively detect whether the hole centers are on the same straight line, a concentricity measuring instrument is used for detection and judgment. When it is judged that the hole centers are on the same straight line, the next step can be performed. When the hole centers deviate, the hole center positions are readjusted. The working principle of the concentricity measuring instrument belongs to the prior art, which will not be described here.

[0036] In order to improve the overall work efficiency and assembly process, the position information when the hole centers of the front and rear lifting deck ear plates 2 and the pile leg ear plate 3 are on the same straight line is measured in advance, and the corresponding installation position is marked according to the measurement result. The front and rear lifting deck ear plates 1 and 2 and the pile leg ear plate 3 are installed according to the marks. This scheme can be understood as that the installation positions of the front and rear lifting deck ear plates 1 and 2 are divided in advance. When the two components are installed in the corresponding positions respectively, it can be ensured that the hole centers of the front and rear lifting deck ear plates 1 and 2 are on the same straight line. This can effectively save the positioning and installation time, and can directly reach the target in one step. In addition, the installation positions need to be adjusted adaptively according to the front and rear lifting deck ear plates 1 and 2 of different sizes or shapes.

[0037] It should be particularly pointed out that the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 are the same structure or the same component, only the setting positions are different.

[0038] In some embodiments, the joint bearing 4 is adjusted in the four positions of front, back, left and right on the leg ear plate 3 through the adjusting mechanism. First, the front and back positions of the joint bearing 4 are adjusted through the adjusting mechanism, so that the joint bearing 4 corresponds to the front and back positions of the leg ear plate 3. Then, the left and right positions of the joint bearing 4 are adjusted through the adjusting mechanism, so that the joint bearing 4 corresponds to the left and right positions of the leg ear plate 3, and then the center position of the joint bearing 4 corresponds to the center position of the leg ear plate 3.

[0039] Optionally, the horizontal height of the boring bar 8 is adjusted through the lifting mechanism, so that the center axis of the boring bar 8 coincides with or is parallel to the straight line of the hole center.

[0040] In order to realize full-automatic operation in the boring process, processing marks are pasted on the positions of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 that need to be bored. A sensor for identifying the processing marks is arranged on the boring bar 8. When the sensor detects the processing marks, the boring bar 8 rotates to drive the boring cutter 9 to rotate to bore the front lifting deck ear plate 1 and the rear lifting deck ear plate 2, respectively. In this scheme, the sensor adaptively senses the processing marks and drives the boring cutter 9 to move to the corresponding position for boring. In the whole process, no manual operation intervention is needed, intelligent automatic processing is realized, and the processing efficiency and accuracy are higher.

[0041] It is worth mentioning that when the boring cutter 9 is used for boring, two boring cutters 9 can be correspondingly arranged according to the distance between the front lifting deck ear plate 1 and the rear lifting deck ear plate 2. In this way, the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 can be bored at the same time, and the processing efficiency is higher. When the boring cutter 9 is used for boring, the boring cutter 9 needs to leave a certain space allowance between the front lifting deck ear plate 1 and the rear lifting deck ear plate 2, so as to facilitate the boring cutter 9 to retreat.

[0042] In addition, as another optional embodiment, a boring device for a ship joint bearing lifting deck ear plate is also provided, as shown in Figure 2As shown, it comprises: a front lifting deck ear plate 1, a rear lifting deck ear plate 2, a pile leg ear plate 3, an articulation bearing 4 and an adjusting mechanism, the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 are arranged horizontally and spaced apart, the pile leg ear plate 3 is installed between the front lifting deck ear plate 1 and the rear lifting deck ear plate 2, the articulation bearing 4 is movably installed on the pile leg ear plate 3 through the adjusting mechanism, the adjusting mechanism can drive the articulation bearing 4 to move relative to the pile leg ear plate 3, so that the hole center position of the articulation bearing 4 is relatively consistent with the pile leg ear plate 3, and then the hole center of the articulation bearing 4 is on the same straight line with the hole center of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2.

[0043] Based on the above scheme, the boring method of the boring device is as follows: the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 are arranged correspondingly in front and back, and the hole centers of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 are adjusted to be on the same straight line; the pile leg ear plate 3 is located between the front lifting deck ear plate 1 and the rear lifting deck ear plate 2, and the hole center of the pile leg ear plate 3 is adjusted to be on the same straight line with the hole centers of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2; the articulation bearing 4 is installed on the pile leg ear plate 3 through the adjusting mechanism, the relative position of the articulation bearing 4 and the pile leg ear plate 3 is adjusted through the adjusting mechanism, so that the hole center point of the articulation bearing 4 corresponds to the hole center of the pile leg ear plate 3, and then the hole center point of the articulation bearing 4 is on the same straight line with the hole centers of the front lifting deck ear plate 1 and the rear lifting deck ear plate 2; after the hole center adjustment is completed, the boring bar 8 and the boring cutter 9 are used to perform boring operation on the front lifting deck ear plate 1 and the rear lifting deck ear plate 2 respectively; after boring is completed, the boring bar 8 is pulled out, the false shaft and the limiting sleeve are installed in the articulation bearing 4, the pile leg is put into the middle of the lifting deck, the false shaft is pushed out from the side using the connecting shaft, and the connecting shaft is connected together through the centers of the front and rear lifting deck ear plates 2 and the articulation bearing 4. Through the corresponding boring method of the device, accurate boring operation can be realized, the connecting shaft can be accurately installed in place, repeated rework is avoided, material cost and labor cost are greatly saved, and labor intensity of workers is reduced.

[0044] Further, the adjusting mechanism comprises a fixing plate 5, a fixing member 6 and an adjusting member 7, the fixing plate 5 is locked on the leg ear plate 3 through the fixing member 6, the adjusting member 7 is movably installed on the fixing plate 5 and connected with the joint bearing 4, the adjusting member 7 can drive the joint bearing 4 to move relative to the fixing plate 5, specifically, the fixing member 6 is a fixing bolt, and the adjusting member 7 is an adjusting bolt. One end of the fixing bolt is fixedly connected with the fixing plate 5, and the other end is fixedly connected with the leg ear plate 3, so that the fixing plate 5 is fixed on the leg ear plate 3, then the installation position of the joint bearing 4 is adjusted through the adjusting bolt, so that the joint bearing 4 and the hole center of the leg ear plate 3 are in the same straight line, and then the joint bearing 4 is locked to prevent it from rolling.

[0045] Optionally, at least two front lifting deck ear plates 1 and two rear lifting deck ear plates 2 are included, the two front lifting deck ear plates 1 are connected through a front fixing frame 10, the two rear lifting deck ear plates 2 are connected through a rear fixing frame 11, so as to form a boring channel, a boring bar 8 is arranged in the boring channel, and a boring cutter 9 is fixed on the boring bar 8.

[0049] (3) Node delay loss cost: delay node for 17 days, 10000 yuan / day X 17 days = 170000 yuan, and 3000 yuan is invested to manufacture a new joint bearing adjusting tool.
