Description

Multifunctional hook box system for offshore floating crane

Technical Field

The utility model relates to a hook case system especially relates to a multi-functional hook case system for marine floating crane.

Background

The demand for floating cranes is becoming higher and higher due to the development of ocean engineering. Besides offshore salvage and construction of ocean engineering, requirements for assembling offshore wind power and large structures are increasing. These new requirements make the functions of the floating crane more diversified, and the form and composition of the hook are therefore more complicated.

The traditional floating crane has a single function. The floating crane mainly comprising salvaging and hoisting is usually accompanied with a four-claw main hook, so that the hoisting capacity is high; the floating crane mainly used for construction and installation is usually provided with two side-by-side two-claw main hooks so as to facilitate turning over and position adjustment. In this case, one hook magazine is provided for each hook. The hook boxes are all built-in (as shown in fig. 12), the hook enters the hook boxes from the upper part, and an operator cannot enter the hook boxes. When the floating crane is in the process of deployment, as shown in fig. 16, each hook must be placed in its own hook box. The hook box can prevent the lifting hook from shaking under the action of sea waves, so that the load acting on the crane is reduced while the lifting hook is protected, the lifting hook is prevented from shaking and striking other parts, and the safety of the whole floating crane can be protected.

In order to enrich the use function of the floating crane and fully exert the economic performance of the floating crane, a combined type lifting hook form appears, as shown in figure 1, the lifting hook is arranged on two parallel claws: the lower part of the first upper lifting hook (2) and the second upper lifting hook (3) is connected with a lower lifting hook cross beam (5) through an upper lifting hook connecting shaft (4) and a lower lifting hook connecting shaft (4), and a lower lifting hook (6) is hung below the lower lifting hook cross beam. This neotype lifting hook form makes the floating crane can be according to the demand, selects suitable lifting hook to carry out the operation. But therefore new requirements are placed on the hook box. The hook box must not only provide support for the hook, but also provide space for the hook to be converted for operation. As shown in fig. 17, a state of storing the combination hook using the conventional hook box is schematically shown, and it can be seen that the conventional hook box does not satisfy the requirements of the hook box of the combination hook.

4. Detailed description of the multifunctional hook box system

The combined lifting hook enters the hook box: when the upper and lower lifting hooks are combined together, the lifting hooks must enter the hook box from the stern to the bow. The lifting hook lifting steel wire rope is lowered downwards, the auxiliary winch on the ship is used for pulling the lifting hook to control the lifting lug 7 to be slowly lowered, the lower lifting hook cross beam 5 can avoid the middle extending beam 1030 of the upper lifting hook, and the combined lifting hook enters the hook box.

The combined lifting hook leaves the hook box: when the upper and lower lifting hooks are combined together, the hook box must be separated from the bow to the stern. The lifting hook lifting steel wire rope is lifted upwards, the lifting hook is pulled by an auxiliary winch on the ship to control the lifting lug 7 to retract towards the stern, so that the lower lifting hook cross beam 5 can avoid the middle extension beam 1030 of the upper lifting hook, and the combined lifting hook leaves the hook box.

Separating the combined lifting hook: when the combined lifting hook needs to be separated, the lifting hook is arranged on the hook box, and the weight of all the lifting hooks is borne by the hook box, so that no load exists on the upper lifting hook connecting shaft 4 and the lower lifting hook connecting shaft 4. An operator stands on a platform of the lower hook overhanging beam 1027, the upper hook connecting shaft 4 and the lower hook connecting shaft 4 are drawn out and detached by using the shaft detaching device, and the upper hook and the lower hook are separated, so that the operation is very easy.

Assembling the combined lifting hook: when the modular hook is to be assembled, only the lower hook 6 is on the hook box and the upper hook enters the hook box from above, as shown in fig. 15. When the upper hook is placed on the hook box, the shaft holes of the upper and lower hook connecting shafts 4 are automatically aligned. An operator stands on a platform of the lower hook overhanging beam 1027, and the upper hook connecting shaft 4 and the lower hook connecting shaft 4 are installed by using the shaft dismounting device, so that the operation is simple and convenient.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
