Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1, the vertical moving tool for the marine turbocharger unit casing comprises a ratchet wrench 1, a hoisting stud 2, a bracket 3, a bearing support seat 4 and a scale 5. The ratchet wrench 1, the bracket 3 and the bearing support seat 4 are all arranged on the lifting stud 2; one end of the bracket 3 is provided with a round hole and sleeved on the lifting stud 2 through the round hole, and one end of the bracket 3 is provided with a casing fixed point; the bearing support seat 4 is arranged between the ratchet wrench 1 and the bracket 3; the ratchet wrench 1 is provided with a switch with a rotatable direction, and the wrench can be guaranteed to rotate in the same direction in the upward or downward moving process through the change-over switch on the ratchet wrench, so that the ratchet wrench is convenient and efficient. The bearing support seat 4 can be pushed by rotating the ratchet wrench 1, so that the bracket 3 is pushed to move up and down along the lifting stud 2; the scale 5 is arranged on the lifting stud 2, and the support 3 is positioned by observing the position of the upper edge of the support 3 on the scale 5.

When the four-group marine turbocharger unit casing vertical movement tool is used, the four groups of marine turbocharger unit casing vertical movement tools are symmetrically arranged at the positions of the 4 corners of the casing, the casing and the casing fixing points of the four groups of brackets 3 are on the same horizontal line, and the positions of the four corners of the casing are respectively fastened and connected by bolts. The four groups of lifting studs 2 are fixed on a machine set base by bolts, and the lifting studs 2 pass through round holes on the bracket 3; the bearing support seat 4 and the bracket 3 are matched through grooves and bosses, so that the bracket can stably and smoothly move up and down. The ratchet wrench 1 is matched with the lifting stud 2, and can move up and down on the lifting stud 2, and the movement of the ratchet wrench 1 can push the bearing support seat 4 to move up and down.
