Amphibian four-pedrail piling machine

Abstract

The invention discloses an amphibian four-caterpillar pile engine, which comprises a working device, a special chassis and a float aiding device, wherein the working device comprises a pile snatching clamp, a pile driver, a pile follower, a gin pole, an inclined strut, a retractable device and a winding. The special chassis comprises a floating box chassis, a supporting leg board, a balance weight, a power device, a transmission device and a control device. The amphibian four-caterpillar pile engine also comprises at least two walking devices, and each of the walking devices comprises a retractable oil cylinder or a supporting leg sleeve capable of controlling the lifting independently, an upright post and a caterpillar mechanism; the retractable oil cylinder or the supporting leg sleeve is fixedly and vertically arranged on the supporting leg board, a piston rod of the retractable oil cylinder is fixedly arranged on the upright post; and under the control of the control device, the power device outputs power to the transmission device, and the power is output by the transmission device to the walking device and the winding. The amphibian four-caterpillar pile engine is used for realizing the piling construction in inshore shoals quickly, safely and reliably.

Description

technical field [0001] The invention relates to pile driving equipment, in particular to an amphibious four-crawler pile driver. Background technique [0002] With the increasingly severe energy situation, the wind power industry has maintained rapid development in recent years, and the wind resources in coastal tidal flats have been effectively utilized, but it is still in the initial development stage. One of the difficulties is the lack of maneuverability in the construction of wind farms in coastal tidal flats. There are two types of existing pile drivers: land pile drivers and offshore pile drivers. [0003] Among them, for land-based piling equipment, such as crawler pile drivers and static pile drivers, although they have good maneuverability and simple construction, they require high ground bearing capacity (MPa level) when driving and piling. When the tidal flat area is at low tide, it is not possible to construct directly on the tidal flat (<50KPa level), and t...

Problems solved by technology

[0003] Among them, for land-based piling equipment, such as crawler pile drivers and static pile drivers, although they have good maneuverability and simple construction, they require high ground bearing capacity (MPa level) when driving and piling. When the tidal flat area is at low tide, it is not possible to construct directly on the tidal flats (<50KPa level), and the equipment is prone to subsidence and overturning; for piling equipment at sea, if construction platforms or special piling ships are used for foundation construction during construction, although they have strong mobility , and can realize rapid sea transportation, but its tonnage is large, the draft is deep, and it cannot be grounded, and it is not suitable for the intertidal zone

In addition, coastal tidal flats have a vast area, complex geology, low bearing capacity and uneven distribution, shallow water level, two tides a day, and unpredictable sea weather. The above two kinds of lifting and piling equipment cannot be used well, so piling construction is carried out. It is a major problem in the construction work in coastal tidal flat areas
