Description
Technical field:
The utility model belongs to technical field of engineering machinery, especially relates to a kind of gantry type subterranean continuous wall hydraulic grab machine.
Background technology:
In water conservancy, the construction of water power underground impervious wall, urban skyscraper, deep foundation construction of diaphragm wall, in the subway construction of diaphragm wall, all need the continuous geosyncline of elder generation in 0.4 meter to 1.2 meters wide of mine working, 50 to 80 meters dark cast-in-place usefulness of diaphragm wall, subterranean continuous wall hydraulic grab machine grooving technology has become now one of state-of-the-art means in the world.But domestic existing subterranean continuous wall hydraulic grab machine all is at high-end hydraulic pressure crawler crane, revolves to dig to bore on the basis and be designed and manufactured into the crawler crane type, and complete machine is in a side of underground wall chase, by the revolution blanking of getting on the bus during construction.Because type is big, complex structure, the hydraulic grab weight that grooving is used is also big, generally at the 15-25 ton, often closely descends the grounding pressure height of wall chase place crawler belt, causes wall chase to cave in easily during construction.
Summary of the invention:
The purpose of this utility model is: the both sides that provide a kind of chassis to be supported on diaphragm wall, can reduce grounding pressure, the reliable gantry type subterranean continuous wall hydraulic grab machine of construction safety.
The technical solution of the utility model is: gantry type subterranean continuous wall hydraulic grab machine comprises chassis, suspension bracket, hydraulic grab, device for discharging, Hydraulic Station, driver's cabin, hoist engine, the chassis comprises the crawler type chassis and is connected platform, suspension bracket, driver's cabin and Hydraulic Station are arranged on the platform, suspension bracket is a planer type structure, gallows frame contains column and the upper beam that is connected column, the platform on column bottom and chassis is hinged, column top is hinged with upper beam, is provided with in the bottom of gallows frame to have device for discharging flexible, turn over function.
The beneficial effects of the utility model are: complete machine structure is simplified, and complete machine weight and manufacturing cost reduce, and have improved construction quality; Because two groups of crawler bogies are supported on the both sides of diaphragm wall, hydraulic grab is arranged on the centre of gantry support, and the stressed of chassis two crawler bogies is tending towards evenly, and the lifting of hydraulic grab is more stable, significantly reduced the grounding pressure on chassis, made work more safe and reliable.
