Problems solved by technology

[0004] Existing products such as laser alignment instruments and dial indicators cannot monitor the alignment of the propulsion engine and the attitude of the raft on-line
CN101813152 discloses an intelligent airbag vibration isolation device, which realizes centering monitoring of propulsion motor rotating machinery with relatively small structural dimensions through 7 displacement sensors, but this device cannot solve the centering measurement caused by the elastic deformation of large raft structures Due to the lack of measurement points, it is impossible to monitor the attitude of large-scale rafts, so it is not suitable for centering monitoring of large-scale vibration isolation systems for propulsion and power equipment

Abstract

The invention relates to a ship propulsion and power equipment large-scale vibration isolation system centering monitoring device. 7 vertical displacement sensors, 3 horizontal displacement sensors, 2 longitudinal displacement sensors and rotation speed and temperature sensors are arranged between a propulsion and power equipment large-scale vibration isolation device raft frame and a hull; a programmable controller, an A / D module, a communication module and a power supply module and the like are integrated in a controller unit; and the communication module has a PC communication interface. A touch display screen, indicating lamps and a switch and the like are integrated on a panel. All of the sensors are connected with the A / D module; the A / D module converts analog signals output by the sensors into digital signals; and the programmable controller calculates the centering state of a propulsion engine under a running status and pose of the raft frame, and the state data is displayed on a touch display screen. The ship propulsion and power equipment large-scale vibration isolation system centering monitoring device is good in real-time performance, high in measurement accuracy, convenient to use and high in intelligent degree, and can realize real-time high-precision monitoring of the ship propulsion and power equipment large-scale vibration isolation device centering state and raft frame pose.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a centering monitoring device for large-scale vibration isolation systems of ship propulsion and power equipment. Background technique [0002] The large-scale vibration isolation system for ship propulsion and power equipment can implement integrated high-efficiency vibration isolation for the propulsion main engine and other multiple power equipment, which can reduce the weight and space occupation of vibration isolation devices while obtaining high-efficiency vibration isolation effects, and overcome the scattered isolation of traditional ships. The vibration isolation effect of the vibration system is not balanced, which is likely to cause the problem of "short plate of vibration isolation effect". The load capacity of large-scale vibration isolation systems for ship propulsion and power equipment can be as high as hundreds of tons. At present, this technology has become...
