The clamping mechanism clamps the deep well pump, and the lower end of the deep well pump together with the clamping mechanism and the fixing mechanism is lowered into the cabin.

[0036] Step 1: Determine the layout of the deep well pump. In civilian ships, the main lubricating oil pump generally adopts a deep well pump. According to the layout of the main lubricating oil circulation tank, the position of the deep well pump can be quickly determined;

[0037] Step 2: Determine the installation position of the lower part of the deep well pump. According to the height of the lower cabin and the deep well pump equipment information, the total height of the deep well pump and the length of the lower part need to be selected. The lower part of the deep well pump can be accurately positioned, and then the bottom lateral support of the deep well pump can be designed. After the size design is completed, the fixed platform 1 is installed to the position where the deep well pump needs to be installed, and the bottom end of the guide rod 61 contacts the bottom of the cabin;

[0038] The specifications of the arc-shaped clamping plate 52 are determined according to the size of the deep-well pump. The initial position of the moving block 73 is in contact with the lower surface of the fixed platform 1. The first motor 33 is started. The first motor 33 drives the reel 32 to rotate. The reel 32 winds the traction rope 34 onto the surface of the reel 32. The lower end of the traction rope 34 pulls the bracket 41 upward. The movement of the bracket 41 drives the support arm 42 to move. The support arm 42 drives the clamping mechanism 5 to move upward, so that the clamping mechanism 5 rises to the fixed platform 1. The bottom end of the deep-well pump is docked with the clamping mechanism 5, and the bottom end of the deep-well pump is placed between the two arc-shaped clamping plates 52. The waist-shaped groove 54 reserves adjustment space for the angle steel 53. When there is a gap between the arc-shaped clamping plate 52 and the bottom surface of the deep-well pump, the nut 56 is loosened to move the angle steel 53, thereby making the arc-shaped clamping plate 52 fit with the surface of the deep-well pump, and then tighten the bolt 55 and the nut 56 to maintain stable clamping of the deep-well pump.

[0039] Step 3: The deep well pump is put in place in advance, the first motor 33 is started, the reel 32 is reversed, the traction rope 34 is released, and the deep well pump is lowered at the same time so that the bottom end of the deep well pump enters the cabin, and the bracket 41 descends, driving the reset mechanism 9 and the fixed rod 43 to descend. When the bracket 41 descends, it drives the guide block 62 to descend, and the guide block 62 drives the position of the linear bearing 63 to descend. The linear bearing 63 slides on the surface of the guide rod 61, and then guides and limits the position of the bracket 41, so that the bracket 41 descends stably, thereby the clamping mechanism 5 and the bottom end of the deep well pump descend stably until the deep well pump is placed on the pump and the deep well pump is installed.

[0040] The fourth step is to drive the second motor 71, which drives the adjusting screw 72 to rotate. The adjusting screw 72 pushes the position of the moving block 73 to drop. The moving block 73 pushes the position of the limiting frame 74 to drop. The limiting frame 74 drives the position of the positioning block 75 to drop. The slope of the positioning block 75 contacts the inclined surface of the triangular pushing block 44. The positioning block 75 continues to drop and pushes the two triangular pushing blocks 44 to move to both sides. The triangular pushing block 44 drives the fixing rod 43 to move. The fixing rod 43 drives the fixing plate 10 to move. The fixing plate 10 drives the anti-slip pad 11 to move until the anti-slip pad 11 contacts the interior wall of the cabin, supporting the cabin wall, and then fixing the position of the bracket 41. The position of the further fixing plate frame 51 is fixed, thereby fixing the position of the arc clamping plate 52 by the angle steel 53, so that the lower end of the deep well pump remains stable during operation. There is no need to perform installation operations between the bulkhead and the deep well pump, which is convenient for installation and support.
