Low-speed Diesel Engine Crankshaft Complex Adjustment and Balance Device

Abstract

The invention provides a re-sleeving balance adjustment device for a low-speed diesel engine crankshaft. The re-sleeving balance adjustment device for the low-speed diesel engine crankshaft comprises a balance cross beam. The right side of the balance cross beam is connected with a centering mechanism. The lower end of the centering mechanism is connected with a hoisting rod. The two sides of the hoisting rod are connected with a hoisting machine through hoisting mechanisms. The left side of the balance cross beam is connected with a counterweight. The counterweight is connected with a fine adjustment mechanism. The fine adjustment mechanism drives the counterweight to move left and right on the balance cross beam. After the re-sleeving balance adjustment device is installed, the position of the counterweight is adjusted through the fine adjustment mechanism, and longitudinal leveling is carried out on a single-sleeve component. The single-sleeve component is leveled in the left-right direction through an adjustment bolt on a steel wire hoisting rope, and the gravity center of the overall structure coincides with the center of a round hole in the upper portion of the single-sleeve component after leveling. Through the re-sleeving balance adjustment device for the low-speed diesel engine crankshaft, rapid leveling of the single-sleeve component can be realized, the leveling accuracy is high, hoisting of the single-sleeve component is stable, and the single-sleeve component is not prone to turn over or tumble.

Description

technical field [0001] The invention relates to the field of crankshaft multiple sleeves, in particular to a low-speed diesel engine crankshaft multiple sleeve adjustment and balance device. Background technique [0002] In the existing shipbuilding industry, when the semi-assembled crankshaft and crank of the high-horsepower low-speed diesel engine are re-set, it is necessary to adjust the single set of components to the following figure 1 As shown in the state, and then carry out lifting assembly. because figure 1 The shape of the single set of components is irregular, and the center of gravity of the single set of components is located at the crank pin, so it cannot be lifted directly with a sling. Therefore, additional loading equipment is required on the single set of components to adjust the balance. Most of the existing crankshaft resetting and balancing devices use counterweight equipment with a single structure. When resetting different types of crankshafts, diffe...
