A special hydraulic trolley for marine engineering equipment modules and its usage method

Abstract

The invention discloses an ocean engineering equipment module special hydraulic trolley. The main body is a rail trolley and further comprises an lifting pump station, a lifting oil cylinder, an energy accumulator and a valve set, wherein the lifting oil cylinder, the energy accumulator and the valve set are fixedly arranged on the upper surface of a base of the trolley, the lifting pump station is arranged outside the rail trolley, and the lifting pump station, the lifting oil cylinder, the energy accumulator and the valve set are mutually communicated through a high-pressure hose. The ocean engineering equipment module special hydraulic trolley is automatically controlled by a set of synchronous control system. The lifting system has a horizontal synchronous function and a pressure balance function, and the pressure balance function can eliminate the lifting oil cylinder overpressure and the damage to a module steel structure which are caused by an uneven foundation. All lifting pump stations are centrally controlled by a set of system and installed on the corresponding special rail trolleys and pushed with horizontal moving speed. The special rail trolley is in displacement closed loop control during lifting, the special rail trolley is in pressure closed loop control during movement, and the configured energy accumulator can improve the pressure balancing accuracy in movement.

Description

technical field [0001] The invention relates to the field of ocean engineering equipment, in particular to a hydraulic trolley dedicated to an ocean engineering equipment module and a method for using it. Background technique [0002] Marine engineering refers to new construction, reconstruction and expansion projects aimed at the development, utilization, protection and restoration of marine resources, and the main body of the project is located on the seaward side of the coastline.

AI Technical Summary

Problems solved by technology

[0003] The module construction method in ocean engineering is a relatively advanced construction method, but the equipment involved in ocean engineering has a relatively large shape and weight. The traditional operation method consumes resources in terms of manpower and material resources, and the efficiency is relatively low.
