An automatic measuring device for shafting bearing load of a ship main engine and its application method

Abstract

The invention discloses an automatic load measuring device for a shafting bearing of a marine main engine and a using method thereof. The automatic load measuring device comprises an intermediate bearing, an intermediate shaft, a cushion block, a supporting seat and an oil pump, wherein the intermediate bearing is fixed to the intermediate shaft; the intermediate bearing comprises an upper cover and a lower cover; the cushion block is arranged between the upper cover and the lower cover; the intermediate shaft is provided with a displacement sensor; the supporting seat is arranged below the intermediate shaft; a jack is arranged between the supporting seat and the intermediate shaft; the oil pump is connected with a high-pressure hose; the other end of the high-pressure hose is connected to the jack; and the high-pressure hose is provided with a pressure sensor. Through the adoption of the automatic load measuring device, the deviation between the pressure value on the jack and a design required value meets the requirement; the operation period is shortened; the labor intensity is lowered; and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the measurement of the shafting bearing load of a ship, in particular to an automatic measuring device for the shafting bearing load of a main engine of a ship and a method for using the same. Background technique [0002] With the increasing size of freight ships, it is becoming more and more difficult to align the propulsion shafting of the ship. The shafting adjustment period of the main engine restricts the important nodes of the wharf outfitting. The outage of ships has brought huge economic losses. The traditional way is to use manual "JACK-UP". [0003] The intermediate shaft used to transmit the power of the main engine of the ship is arranged on the intermediate bearing, and the intermediate bearing is supported on the auxiliary machine platform fixed on the hull through support bolts. The jack used to measure the load of the intermediate bearing is installed on the support to lift the intermediate shaft, and the jac...

AI Technical Summary

Problems solved by technology

[0004] At present, in the shipbuilding industry, it is difficult for domestic and foreign shipyards to install the shafting at one time to achieve a reasonable distribution of bearing loads. Usually, it is necessary to adjust the bearing displacement to make each bearing load meet the requirements of shafting alignment. Main engine shafting bearing load adjustment mainly uses the above The manual lifting measurement method, and has not yet applied systematic, automated, and intelligent measuring equipment, still remains at the level of manual work, the operation cycle is long, the labor intensity is high, and manual repeated visual reading increases the reading error
