Abstract

The invention relates to a floating structure and can be used to create floating cranes. The device allows to increase efficiency in operation. On the pontoon 1 of the floating crane in the nasal mid-section, a crane 2 with an arrow 3 is installed. The nose tip noHTot; a is made with a supporting trough-shaped console 4. The crane has a column 5 with a skid trolley 6. The skid trolley is equipped with rollers 7 and similar rollers 8 mounted in the side sloping niches 9, 10. 4 Il.

The invention relates to floating construction and can be used to create floating cranes for hydraulic engineering works and servicing high-breasted craft.

The purpose of the invention is to increase efficiency in operation.

FIG. 1 shows the floating in the traditional conditions of work, a general view; in fig. 2- the same, when working with unequipped

It is not only maximally forward along the nose beyond the nasal perpendicular of P, but also upwards. As a result, the crane 2 with its boom 3 is able to serve a significant part of the coastal strip, keeping the underwater parts of the pontoon 1 intact. Due to the fact that the crane 2 rises along the inclined plane of the support console 4 during movement towards the nose, favorable conditions are created saving; in fig. 3 - the same, during the work of 10 serving high-toned ships C (Fig. 3). in a high-breasted ship; in fig. 4 - view A for moving to another place of work. 2. With the removal larger than that allowed on the pontoon 1 of the floating crane in the area of the noso-register, the crane 2 is transferred to the traveling mid-section, the crane position is set. For this purpose, for example, polysp2 with boom 3. The nosal end of the mechanism (not shown) of the oblique pontoon is made from the supporting cortex-shaped carriage 6 with crane 2 and is diverted from

4. The crane has a column 5 with a skid carriage 6. The braid carriage has rollers 7 and similar rollers 8 mounted in side inclined recesses 9, 10. Rollers interact with guides 11 on deck 12 on the support console. The console itself is made folding on the hinge 13.

It is more expedient to carry out the movement of the scythe trolley carriage in the form of a well-known tackle (not shown), although 25 may be screw or hydraulic.

In the current position, the boom 3 of the crane 2 is laid on a support in the superstructure H (not shown). The braid 6 is fixed to the rails 11. In the working position, when maintenance is not required

If the supporting console 4 is not needed according to the conditions of the present work, then it is pivoted at the hinge 13 to the stowed position.

The differential of the pontoon in the case where the crane 2 is located on the support bracket 4 is produced by known means, i.e. in the pontoon there is an appropriate ballast system with tanks for liquid ballast in the bow and stern. In this case, the nasal tanks are drained and the feeding tanks are filled. As a result, due to the redistribution of the masses (ballast water and crane 2), the pontoon 1 remains in position either on an even keel, or with a small trim at the stern. It should be borne in mind that in working condition on the console.4, the crane 2 is located behind the nose perpendicular P, i.e.

During the shore protection works, the construction of moorings, etc. due to the small depth of water near the unequipped shore, the pontoon 1 of the floating crane, having a large draft, cannot get close to the shore. In this case, the support console 4

Invention Formula deployed on the ptrnir 13 towards the shore. In this position, the support console A floating crane, comprising a housing and a lifting device, located on a supporting carriage with rollers on which this carriage is mounted so as to 4 is fixed by known means. Further, the 45 movements along the deck-guiding corpora-pulp mechanism (not shown) the crane 2 is moved on the skidding trolley 6 rollers 7 along the guide rails 11 until the meeting of the rollers 8, located in holes 9 and 10, with the rails 12 on the support console. At the same time, the central part of the skid carriage 6 is placed in a trough-shaped niche of the support console 4, and the rollers 8 change along the guides 12 installed on the sides of the support console 4, the crane hollow and the surface support consoles attached to the end of the crane body, differing from that, in order to increase efficiency in operation, in a certain support arm is located above the deck at an angle to it, and the support cart is provided with lateral projections, the lower surfaces of which are made with bevels corresponding to the slope of the upper slopes consoles, and are equipped with additional katnennoy with lift. Thus, the crane 2 to mate with the aforementioned top with the help of the trolley carriage 6, moving surfaces of consoles. With this mechanism (not shown), the skid carriage 6 with crane 2 is retracted with supporting console 4 to its original position (Fig. 1). If necessary, the boom 3 is lowered onto the aft superstructure, where it is attached in a traveling manner. If the supporting console 4 is not needed according to the conditions of the present work, then it is pivoted at the hinge 13 to the stowed position.
