Description

Technical Field

[0001] The utility model belongs to the technical field of ships, and particularly relates to a device for simulating ship shaft alignment teaching. Background Art

[0002] During the shipbuilding process, the main engine shaft system needs to be installed and aligned. The quality of the shaft system installation and alignment is directly related to the reliability of the main engine propulsion system and the safety of the ship's navigation. The installation and alignment of the shaft system are based on the theoretical center line of the shaft system.

[0003] Shaft alignment is to install the shaft system into a certain state according to certain requirements and methods, in which the stress in each shaft section of the shaft system and the load on all bearings are within the allowable range or have reasonable values, so that the shaft system can operate reliably. The essence of shaft alignment is to accurately determine the position of the main engine bearing. Whether the ship's shaft system can operate reliably depends not only on the structural design, material and manufacturing of the shaft system, but more importantly on the quality of the shaft system installation. Poor quality of shaft alignment installation will cause bearing heating, excessive wear of the tail bearing, damage to the sealing device and shaft system vibration. Therefore, shaft alignment is to arrange the shaft system into a certain axis state according to certain principles and methods, so that the load on each bearing, the stress, bending moment, and rotation angle in each shaft section are as close to the allowable value as possible or obtain reasonable values, so as to ensure the safe and reliable operation of the shaft system. At present, after the main engine shaft system of the ship is aligned and installed, it will be measured and accepted. However, during the acceptance process, it is inconvenient to measure the alignment data of the ship's main engine shaft system on site. When the supervisor has questions, it is impossible to explain clearly on site. If the ship's main engine shaft system is aligned and reinstalled to obtain the alignment installation data, it will be time-consuming and labor-intensive, which will increase the production cost of the ship and is not conducive to enterprise production and improving economic benefits.

[0028] Next, the working principle of the embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0029] The first angle steel and the second angle steel play a supporting role, and are used to support the rotating shaft, the first flange and the second flange; the adjustment frame is used to adjust the position of the second flange; the first flange and the second flange are on the same axis, and the second flange can rotate around the rotating shaft; when the second flange rotates, the dial indicator rotates with the second flange, and the measuring head of the dial indicator rests on the first flange. By reading the reading of the dial indicator, the offset between the first flange and the second flange can be known.

[0030] When using the device to teach the alignment of a simulated ship shaft system, the second flange is rotated; the second flange is rotated from 0° to 90°, then from 90° to 180°, then from 180° to 270°, and then from 270° to 360° (back to the starting point) to measure whether the position between the second flange and the first flange is concentric and vertical (i.e., offset and twist); in addition, by changing the vertical or horizontal position of the adjustment frame to adjust the relative position of the second flange, the twist offset value set for the alignment of the simulated ship shaft system can be achieved.

[0037] The transverse lead screw and the transverse threaded rod are used to adjust the transverse position of the second flange, and the longitudinal lead screw and the longitudinal threaded rod are used to adjust the longitudinal position of the second flange. A mounting groove is provided in the middle of the sliding base, and the transverse threaded rod is horizontally installed in the mounting groove in the middle of the sliding base; when the transverse threaded rod rotates, the transverse lead screw moves on the transverse threaded rod, and drives the slider to move along the sliding guide rail through the second connecting rod.

The L-shaped plate is installed on the outside of the four corners of the support plate. The L-shaped plate is provided with a through hole, and a nut is provided on the outside of the through hole; the adjustment bolt is screwed into the nut and passes through the through hole on the L-shaped plate to press against the side of the support plate, fixing the support plate on the inside of the L-shaped plate.

[0046] The working principle of this embodiment is the same as that of Embodiment 1.

[0047] Example 6

[0048] The difference between this embodiment and Embodiment 5 is that the dial indicator stand is U-shaped; the left end of the dial indicator stand is connected to the second flange, the middle part is located on the outside of the first flange, and the right end is located on the right side of the first flange; dial indicators are respectively installed in the middle and right end of the dial indicator stand, the measuring head of the dial indicator installed in the middle of the dial indicator stand rests on the circumferential edge of the first flange, and the measuring head of the dial indicator installed on the right side of the dial indicator stand rests on the side of the first flange.

[0050] The middle and side of the dial indicator stand can be equipped with dial indicators to monitor the outer circle and the plane at the same time. For some bearings with larger movement, two dial indicator stands can be symmetrically installed on the second flange, and dial indicators can be installed in the middle and side of the dial indicator stand at the same time. This can balance the left and right ends of the second flange in the horizontal direction and will not rotate due to gravity, making it convenient for staff to take measurements and readings.

[0051] The working principle of this embodiment is the same as that of Embodiment 1.
