Problems solved by technology

It is often difficult for land-based lifting equipment and underwater floating cranes to enter the site, especially due to the influence of high tides and low tides and strong winds and waves. Ordinary lifting machinery will encounter more difficulties, and offshore floating cranes cannot For some construction operations on water, it is sometimes required that the hook cannot swing arbitrarily, and it is difficult to meet this requirement by using floating cranes in water; on the other hand, the cost of floating cranes is relatively high, which is not conducive to controlling construction costs

Embodiment Construction

[0028] Referring to Fig. 1-Fig. 15, a crane for beach sea operation includes main buoyancy tank, stable buoyancy tank, pile legs, lifting hydraulic jack, jacking hydraulic jack and lifting crane. The combined structure of automobile transportation, its main pontoon 1 is a closed hull structure, a crane 10 is installed in the upper middle part, and a connecting beam 8 is installed in the front and rear parts respectively, and the end of the connecting beam is installed with a stable Floating box 2, pile legs 3 and lifting hydraulic jack 5 are installed on this stable floating box, and jacking hydraulic jack 9 is installed at the main pontoon rear end.

[0029] The stable buoyancy tank 2 is a circular, oval, square, rectangular or diamond-shaped structure, and a hole is arranged in the middle, and a pile leg 3, a lifting hydraulic jack 5, and an annular sleeve 6 are installed in the hole, and a bearing is installed at the lower end of the pile leg. The pressing plate 4 is evenly...

Abstract

The offshore operation sinker wheel machine comprises the main floating box, stable floating box, leg well, lift hydraulic jack, push hydraulic jack, crane, with each part detachable. The main floating box is in enclosed boat structure, with the middle installed with crane, fore and back installed with linking beam, with the end installed with stabilizing floating box that installs with leg well and lift hydraulic jack and push hydraulic jack at the rear of the main floating box. Due to the tow jacks, it can solve the displacement of the sinker wheel machine. The crane can meet the needs for construction and goods unloading. It mainly applies to offshore hoisting operation or loading alike jobs.

Description

1. Technical field [0001] The invention relates to hoisting equipment used in tidal flats, coastal intertidal zones, shallow waters and rivers and lakes for lifting construction operations and loading and unloading goods, in particular to a crane for beach operations. 2. Background technology [0002] There are various types of cranes for land construction and lifting of goods, and there are various floating cranes for rivers and sea areas with normal water depths. However, there is currently a shortage of construction and lifting goods in various mud flats, coastal intertidal zones and shallow waters. An ideal lifting device. It is often difficult for land-based lifting equipment and underwater floating cranes to enter the site, especially due to the influence of high tides and low tides and strong winds and waves. Ordinary lifting machinery will encounter more difficulties, and offshore floating cranes cannot For some construction operations on water, it is sometimes requ...
