Tool and method for removing thrust block of marine low-speed diesel engine

Abstract

The invention discloses a tool for taking out thrust blocks of a marine low-speed diesel engine. The tool comprises a base plate and a pair of connecting blocks. The base plate comprises a straight plate and inclined wing plates, wherein the inclined wing plates extend from the upper end of the straight plate to the two sides. The shapes of the connecting blocks are matched with the shapes of theouter ends of the inclined wing plates, the connecting blocks are fixed to the outer ends of the inclined wing plates, and radial through holes and axial through holes are further formed in the connecting blocks. The lower side faces of the two connecting blocks which are inclined are splayed and supported on the disc-shaped periphery surface of a crankshaft thrust disc. A method of using the toolfor taking out the thrust blocks of the marine low-speed diesel engine comprises the different steps that the obverse running face thrust blocks are taken out, the reverse running face thrust blocksare taken out, wherein the tool is fixed to the crankshaft thrust disc and a crankshaft chain wheel, a crankshaft is rotated, and the tool pushes the thrust blocks to rotate to the positions with thefeatures that the arc-shaped surfaces of the large ends of the thrust blocks are upward, and hoisting is convenient. The tool for taking out the thrust blocks of the marine low-speed diesel engine issimple in structure, the method is simple and convenient to use, and the disassembly efficiency and the disassembly safety of the thrust blocks are improved.

Description

technical field [0001] The invention relates to a maintenance and disassembly tool for a low-speed marine diesel engine, in particular to a tool and a method for taking out a thrust block of a low-speed marine diesel engine, and belongs to the technical field of diesel engine maintenance. Background technique [0002] The marine low-speed diesel engine is the power plant of the 10,000-ton ship, and the marine diesel engine with a speed of 90-200r.p.m is defined as the marine low-speed diesel engine. The thrust end of the marine low-speed diesel engine is connected to the marine gearbox, and the marine gearbox is connected to the marine propeller through the shaft system. After the power output by the marine low-speed diesel engine is changed, it drives the rotation of the marine propeller to provide power for the ship to sail. Such as image 3 Shown, it is the crankshaft thrust plate 30 on the crankshaft of the marine diesel engine and the thrust block of the machine base th...

AI Technical Summary

Problems solved by technology

The existing thrust block adopts the method of installing lifting screws on the side and directly lifting it out of the installation groove 101. The open space at the top of the installation groove 101 is small, and it is difficult to lift the thrust block and there are potential safety hazards
