Problems solved by technology

In the traditional airbag control system, the operator observes the airbag height and airbag pressure, manually opens the air pressure valve, and controls the inflation and deflation of the airbag. The control accuracy is low and the operation is cumbersome.
Intelligent airbag height control adopts PLC or embedded PC as controller, high-speed solenoid valve as actuator, displacement sensor and pressure sensor as feedback signal, and different pipelines are used for airbag inflation and deflation. When the number of airbags is large, the whole The system is very complex, which increases the probability of failure and the difficulty of maintenance

Embodiment Construction

[0012] Referring to the accompanying drawings, the airbag control device for ships based on the altitude valve includes: a shock-absorbing airbag 1, an altitude valve 2, a high-pressure gas cylinder 3 and a support mechanism 4;

[0013] The upper and lower ends of the shock-isolation airbag 3 are installed between the equipment foot 7 and the bottom plate 8 to be isolated through the base 5; the height of the support mechanism 4 is adjustable, and it is also installed between the equipment foot 7 and the bottom plate 8 ;

[0014] The height valve 2 is installed on the equipment foot 7 through the mounting plate 6, its air inlet 2-1 communicates with the high-pressure gas cylinder 3, its airbag interface 2-2 communicates with the shock-absorbing airbag 3 through the connecting hose 9, and its exhaust Port 2-3 communicates with the atmosphere, and its main shaft 2-4 is hinged with one end of control rod 10; the other end of control rod 10 is movably connected with pull rod 11 hi...

Abstract

The invention belongs to the field of vibration isolation of ships and particularly relates to an air bag control system for a ship. An altitude valve-based air bag control device for a ship comprises a vibration isolation air bag, an altitude valve, a high pressure gas cylinder and a supporting device; when the total weight of equipment is increased, the height of the vibration isolation air bag is decreased to drive the altitude valve to descend, the rotating angel of a main shaft is increased, the air inlet of the altitude valve is opened, and gas in the high pressure gas cylinder enters the vibration isolation air bag through the altitude valve, so that the vibration isolation air bag is raised; when the total weight of the equipment is decreased, the height of the vibration isolation air bag is increased to drive the altitude valve to ascend, the rotating angle of the main shaft is decreased, the exhaust port of the altitude valve is opened, and gas in the vibration isolation air bag enters the air from the exhaust port. The composition of the control system is simplified to satisfy different control precision requirements. The supporting device of the control system has a height adjusting function, is used for arranging the initial operational height of the altitude valve, and plays a protective role after the air bag works normally.

Description

technical field [0001] The invention belongs to the field of ship vibration isolation, in particular to an air bag control device for ships. Background technique [0002] In the field of ship vibration isolation, compared with the commonly used rubber vibration isolators, the airbag shock absorber has a lower natural frequency, and the vibration isolation effect is more significant, so it is widely used. In order to meet the centering requirements and levelness requirements of the airbag support equipment, the airbag height control system is used to control the inflation and deflation of the airbag. In the traditional airbag control system, the operator observes the airbag height and airbag pressure, manually opens the air pressure valve, and controls the inflation and deflation of the airbag. The control accuracy is low and the operation is cumbersome. Intelligent airbag height control adopts PLC or embedded PC as controller, high-speed solenoid valve as actuator, displace...
