Problems solved by technology

The steps of the self-shifting operation of the crane are cumbersome, and there is a problem of poor maneuverability. Especially for the equipment steering operation, the above steps need to be repeated many times to complete; and further affect the construction efficiency of the offshore wind field

Embodiment Construction

[0034] The present invention provides an amphibious crawler crane aiming at the characteristics of coastal beaches or extremely shallow seas, so as to safely and reliably realize the hoisting construction of materials. There is a column telescopic mechanism; in this way, during the construction process, it is easy to complete the displacement and steering operations of the whole machine, thereby improving the construction efficiency of the coastal wind field; in addition, the height of the chassis can also be adjusted according to the height of the sea water, so that it can be exposed when the tide rises The water surface avoids the impact of waves, so that the amphibious crawler crane can be normally hoisted and constructed in tidal flat areas, greatly improving its operating performance and safety.

[0035] The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0036] See figure 1 , which is a three-dimensional schematic di...

Abstract

The invention discloses an amphibious crawler crane, which comprises a loading turntable, a chassis, a floating-assisted device and a running device. The loading turntable comprises a lifting device, a turning device, a power device, a transmission device and a control device; the chassis is used for bearing the loading turntable; the floating-assisted device is connected with the chassis, wherein power of the power device is output to the transmission device and output to actuating mechanisms through the transmission device, namely the running device and the lifting device; and the running device comprises a crawler mechanism and an upright post telescoping mechanism, and the upright post telescoping mechanism is arranged between the chassis and the crawler mechanism so as to adjust the height of the chassis. By adopting the crawler running mechanism, the amphibious crawler crane is easy to complete displacement and steering operation of the whole crane, and has low ground pressure so as to improve the construction efficiency of offshore beach wind fields; in addition, the upright post telescoping mechanism is arranged between the chassis and the crawler mechanism, so the amphibious crawler crane can adjust the height of the chassis according to the depth of seawater so as to avoid shock of ocean waves, and has the advantage of safe and reliable operation.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an amphibious crawler crane. Background technique [0002] With the increasingly severe energy situation, the wind power industry has developed rapidly in recent years, and wind resources in coastal tidal flats have been effectively utilized. In the construction of coastal tidal flat wind farms, mobile, safe and reliable lifting equipment is required. And existing hoisting equipment has two types: land crane and offshore crane. [0003] Among them, for land-based hoisting and hoisting equipment, such as crawler cranes and all-terrain cranes, although they have good maneuverability in land transfers, they require a high ground bearing capacity (MPa level) when driving and hoisting, and cannot be used directly when the tide is low. Construction in tidal flats (KPa level); for offshore lifting equipment, such as large crane ships, although they have strong lifting cap...
