Description

The invention relates to the operation of the fleet and, in particular, to devices for lifting the floating grillage pier. .

A device for lifting 5 floating grillage pier, including columns, mounted on the ground water area, as well as pontoons with a ballast system, mating by means of hinge joints of locks with sides of the pier grout pier pier [1 ^.

A disadvantage of the known device is the low reliability and inconvenience in operation.

The purpose of the invention is to increase the reliability of operation and ease of use of the device.

This goal is achieved by the fact that the device is equipped with racks with locking elements, one ends 20 of which are attached to the pontoons, and each Lock hinge assembly contains a L-shaped bracket and a butt, while the L-shaped bracket is mounted on the lock, and each butt is fixed on 25 the other end of the rack and made mating with the L-shaped bracket, and the lock is made with the supporting element mating with the locking element of the racks. In addition, fix-30

The supporting element of the rack is made in the form of an additional butt, and each supporting element of the lock contains a groove mating with an additional butt.

FIG. 1 shows schematically a device for raising a floating grillage of a pier, general view; in fig. 2 — device before raising the floating grillage of the pier; in fig. 3 shows the moment of installation of the racks on the pier floating grillage of the pier; in fig. 4 - device-®stvo for raising the floating grillage of the pier.

A device for lifting a floating pier grillage 'contains pontoon buoyancy 1 with ballast systems for filling with water and blowing air. The support columns 2 and locks 3 mounted on them are fixed on board the floating grillage 4 of the pier for the duration of the ascent. Racks 2 have the top 5 butts of the hinged attachment point to the floating grillage and the bottom 6 have additional supporting butts of the fixing element. The top butts 5 are attached to the L-shaped brackets ’7 of the hinge assembly by inclining the device. Lower supporting additional butts 6 enter into vertical grooves 8 of the lock when blowing pontoons3

buoyancy 1 in order to raise the floating grillage 4 above the water surface for fixing on the columns 9.

The device works as follows.

'Locks 3 according to the number of pillars 2 are fixed in the right places on the sides of the floating grillage 4 installed afloat in the place where the pier was erected and previously fastened by the columns 9 sunk into the ground and passed through the holes in the. grillage 4. Pontoons-buoyancy 1 with the uprights afloat are fed to the floating grillage 4 and are tilted with the help of delays so that the upper ends of the uprights 2 are inserted between the L-shaped brackets 7 locks 3 and held there by upper supporting butt heads 5 · in engagement with Г -shaped brackets 7. After this, the compartments of the pontoons-buoyancy 1 are flooded with water, and they are immersed in water until they are hung in locks 3 on the upper butt-rests 5. Then the pontoons-buoyancy 1 are blown with air and they float, while the lower additional bearing poles soup 6 includes grooves 8 in the vertical support elements locks 3 and 4 floating grillage rises at columns 9 to the desired mark, respectively adjustment racks 2 and there fastened to the columns 9 by means of, for example, Snarky. After fixing the grillage 4 on the columns 9, the pillars 2 of the device are disengaged from the lock 3, and the device is retracted, and the locks 3 are removed.

The vertical loads from the weight of the floating grillage 4 during lifting are perceived by the lower additional butts 6. The upper butts 5 serve to wind down the device and perceive the moments of forces possible when lifting the grillage 4. The stability of the system — the floating grillage 4 on submerged pontoons-buoyancy — is provided by columns 9 submerged in the ground in advance, and its own underwater stability of the pontoons, part 1.

Filling of pontoons with buoyancy 1 with water (ballasting) and blowing them with air is carried out in the usual way with the help of compressors installed either on diving boats • (saddle), or directly on the raised floating grillage of the berth under construction.
