Hoisting tool for cylinder unit of V-shaped diesel engine

Abstract

The invention discloses a hoisting tool for a cylinder unit of a V-shaped diesel engine. The hoisting tool comprises an arched hoisting tool main body and two shackles; the arched hoisting tool main body comprises a cross beam part, a left supporting leg, a right supporting leg, a left bottom plate and a right bottom plate; the cross beam part is provided with a row of lifting holes, the row of lifting holes comprises two lifting holes or more, and the two shackles are respectively and selectively arranged in the two lifting holes; the upper end of the left supporting leg is connected with theleft side of the cross beam part, and the lower end of the left supporting leg is connected with the left bottom plate; the upper end of the right supporting leg is connected with the right side of the cross beam part, and the lower end of the right supporting leg is connected with the right bottom plate; and bolt mounting through holes are formed in the left bottom plate and the right bottom plate. According to the hoisting tool for the cylinder unit of the V-shaped diesel engine, space height required for hoisting the cylinder unit is small, and the cylinder unit can be quickly switched between a vertical state and an inclined state conveniently.

Description

technical field [0001] The invention relates to diesel engine technology, in particular to a hoisting tool for a V-type diesel engine. Background technique [0002] Repairing the V-type diesel engine requires a short repair time and requires that all parts of the cylinder unit can be replaced in the cabin. For this reason, the cylinder unit of existing V-type diesel engine adopts modular design usually, mainly comprises components such as cylinder head, cylinder liner, water jacket, air valve, valve seat, rocker arm. When replacing the water jacket, cylinder liner, piston assembly, and connecting rod, the assembly of the cylinder unit, piston, and connecting rod shaft must be disassembled together. [0003] The spare parts of the cylinder unit of the V-type diesel engine are placed in a vertical state. At the same time, the gap between the cylinder head and the cylinder head bolts, the cylinder liner and the body is small. There is a certain angle in the direction. At pre...

AI Technical Summary

Problems solved by technology

In this way, there is interference between the chain hoist and the rocker arm seat, and the rocker arm mechanism needs to be removed to disassemble and install the cylinder unit. The space required for hoisting is relatively high, and the space in the cabin sometimes cannot meet the hoisting requirements.

In addition, the speed of adjusting the angle of the cylinder unit hoisted by a chain hoist is slow, which increases the time for maintenance and disassembly, and sometimes cannot meet the time limit for replacement

Furthermore, when adjusting the angle of the cylinder unit with a chain hoist, there is no angle measuring device, and it is easy to cause stagnation due to angle deviation
