Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The present invention aims at the problems of low installation accuracy, high labor load and high work difficulty of the existing dredger cutter shaft alignment method, and provides a dredger cutter shaft alignment method, which can solve the problems existing in the prior art. The installation accuracy is low, the work is difficult and the labor load is large, and the installation cycle is long.

[0032] The determination of the theoretical center line of the ship's shafting system and the alignment and installation of the shafting system are key processes in the shipbuilding process. The quality of alignment and installation will directly affect the reliability and durability of the ship's main engine, shafting and other equipment. sex. The present invention promptly passes to 4000m 3 / h Discussion on reasonable alignment m...

Abstract

The invention provides a method for centering the shafting of a reamer of a dredger, solving the problems in the prior art, such as low installation accuracy, high working difficulty, high workload and longer installation period. According to the technical scheme, the method comprises the following steps: a. looking for a shafting theoretical center line; b. mounting a laser transmission device; c. placing a plurality of fulcrum bearing blocks, and regulating each fulcrum bearing block according to the laser line; and d. mounting a reamer shaft and an intermediate shaft, and connecting the whole shafting. All data after the mounting of the reamer shafting is within the calculation requirement range and the reamer shafting also passes an austere dredging test trial; the shafting and each device are in a good working condition without abnormal vibration or noise, no bearing has an obvious heating phenomenon, and the design requirement is reached.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and relates to the alignment and installation of the shafting of a ship, in particular to a method for aligning the shafting of a dredger cutter. Background technique [0002] Usually, the alignment and installation of the shaft system adopts the flat axis method, that is, the positional relationship of the flange planes connecting the two shaft systems is adjusted by adding temporary supports (measurement offset value, tortuous value), so that it can reach the calibration calculation book The school requirements in China are sufficient. 4000m 3 / h The weight of each shaft of the dredger is about 2 tons. If the shaft system is aligned by the horizontal shaft method, it will undoubtedly increase the difficulty of the work and the labor load, and also increase the installation cycle and installation accuracy. Low. [0003] Considering the analysis of the characteristics of the entire reamer...
