Abstract

The invention provides an electric hydraulic grab bucket for a dredge boat. The electric hydraulic bucket comprises a bearing structure, a dual-flap bucket body, a synchronous structure, a connectingstructure and a hydraulic power system; one end of the bearing structure is connected with one end of the connecting structure, the other end of the connecting structure is used for being connected with a lifting device, two bucket bodies of the dual-flap bucket body are rotatably connected to the bearing structure, the hydraulic power system is used for driving the two bucket bodies of the dual-flap bucket body to be opened and closed, and the synchronous structure is used for synchronizing opening and closing of the dual-flap bucket body. The hydraulic power system is arranged in the bearingstructure, a long-distance hydraulic pipeline is avoided, deep ocean work capacity is improved, the dual-flap bucket body can achieve synchronous opening and closing, grabbing controllability is good, and the bucket has the beneficial effects of being large in bucket capacity, simple in structure, convenient to assemble and simple in manufacturing process.

Description

technical field [0001] The invention relates to the technical field of dredging equipment for engineering ships, in particular to an electro-hydraulic grab bucket for dredging ships. Background technique [0002] The dredger grab is mainly used to dig out various silt, mud, sand, gravel, gravel, boulders and other materials from the seabed. It can also be used for channel dredging, wharf construction and seabed engineering. Waterway port facilities such as ponds, anchorage wharves are inseparable from dredger grabs. [0003] In recent years, with the rapid development of dredging equipment technology and social economy, the development of marine resources has gradually advanced from offshore shallow water areas to far sea deep water areas. Occupying a very high proportion, it provides a broad market for the construction of large grab dredgers. The 4m currently used in the market 3 、8m 3 and 13m 3 For grab dredgers, the capacity of the grab bucket is generally small, and...
