Problems solved by technology
[0002] When installing and dismantling the tail shaft of a ship, due to the lack of a fulcrum, it is necessary to carry out lifting operations through lifting lugs, slings and chain hoists on the hull structure. However, because it is an aerial operation, the tail shaft will still shake during the process of pumping and plugging phenomenon, it is very easy to cause the shaft center to deviate from the axis, thus damaging the surface of the stern shaft and the stern tube bearing, and causing quality problems

Embodiment Construction
[0015] Such as figure 1 As shown, a tail shaft installation and removal method includes the following steps:
[0016] Step 1: Place the support tooling at the fulcrum position, the bottom support 1 is an H-shaped structure, and it is properly spot-welded with the hull structure to ensure stability;
[0017] Step 2: By turning the lateral displacement bolt 3 on the wedge-shaped structure 2, adjust the vertical height of the roller support 4 to realize the change of the axis position of the tail shaft, so that the center of the tail shaft is consistent with the axis position;
[0018] Step 3: Tighten the vertical fastening bolt 5 to ensure the fastening of the roller support 4 and the bottom support;
[0019] Step 4: Under the action of other hoisting tools, the tail shaft is installed and disassembled. The tail shaft can travel without wear on the double-row deep groove ball bearings on the supporting tool.
[0020] The support tooling includes a bottom support 1, a wedge str...

The invention discloses a method for mounting and dismounting a tail shaft. The method for mounting and dismounting the tail shaft comprises the following steps that 1, a supporting tool is placed ata fulcrum position, a bottom support is a H-shaped structure, spot-welding is properly conducted on the bottom support and a ship body structure to ensure the stability; 2, the vertical height of a pin roller support is adjusted by screwing a transverse displacement bolt on a wedge-shaped structure, so that the axis position of the tail shaft is changed, and the center of the tail shaft is consistent with the axis in position; 3, a vertical fastening bolt is tightened to ensure the fastening of the roller support and the bottom support; and 4, the tail shaft is mounted and dismounted under theaction of other hoisting tools, and the tail shaft can advance on a double-row deep groove ball bearing on the supporting tool without abrasion. According to the method for mounting and dismounting the tail shaft, through the fulcrum for placing the tail shaft, fine adjustment of the height is achieved by adjusting bolts on the supporting tool, focusing of the axis of the tail shaft is guaranteed, meanwhile, it is guaranteed that the tail shaft is in a stable state in the mounting and dismounting process, and the technical problem that the tail shaft shakes in air and deviates from the axis in traditional mounting is solved.
Description
technical field [0001] The invention relates to an installation and disassembly method, in particular to a tail shaft installation and disassembly method. Background technique [0002] When installing and dismantling the tail shaft of a ship, due to the lack of a fulcrum, it is necessary to carry out lifting operations through lifting lugs, slings and chain hoists on the hull structure. However, because it is an aerial operation, the tail shaft will still shake during the process of pumping and plugging Phenomenon, it is very easy to cause the shaft center to deviate from the axis, thereby damaging the surface of the tail shaft and the stern tube bearing, and causing quality problems. Contents of the invention [0003] The purpose of the present invention is to provide a method for installing and dismounting the tail shaft. [0004] The technical scheme adopted in the present invention is: [0005] A tail shaft installation and removal method, characterized in that: comp...
