Description

one

The invention of op issit to sudo1ro1.

There are methods with; methods and devices for ships} from ships from the stocks to the node, in which ships are transplanted from the berths to the skid carts, they are lowered over the slope) П {Ь1М rail: m stationary trunk 1 sobdochi system 1.

It is also known a device for launching a sea self-climbing standard form onto water containing a slipway. c: 1babbed with full-wave and curvilinear, m-ramming with pels and WAYS with trolleys located on the FIHX-11 Slipway, and also a section of curvilinear rails of the X ways located in the water zone of the southern space, and underwater rotary base installed at the 15 kV section, located at the water level of 15 kp and 14 underwater. the walls of the stocks in the center of the bend radius of the curve of the curve 2j.

The disadvantage of these devices is the number of planes, the railroad tracks and the big 2o cost of their maintenance. 1 takeover The goal of a Mjoopc ge.ch is C even one laborious: -; descent platform s collecting on the water and control (design.

The goal of the device is achieved by the fact that the device is equipped with underwater and coastal supports and watercrafts mounted on these supports, while the curved track section is located on the deck of the floating equipment for joining with the curved track rails in a horizontal plane.

The device contains a slipway, equipped with straight 2 and curvilinear 3 slipway railways, on which the slipways 4 and 5 are installed. The slipway 394 1 has a vertical wall 6 with a shore support 7. In addition, the device has a rotatable base 8 mounted on the ground E., located at the center of the bend radius of curvilinear tracks 3, the watercraft 9 with the curvilinear tracks 0 (which are a continuation of the curvilinear paths 3) and the underwater supports 11 of the watercraft 9. The floating equipment 9 has a ballast system ings (not shown in the drawing). The platform 12 of a triangular shape contains a lifting mechanism and support columns And, 15 and 16. The device operates as follows. The floating craft 9 leads up to the wall 6 of the stocks 1 and is installed on the banks on support 7 and underwater supports 11 so that the curved rail tracks 10 on the deck of the boats 9 constitute a continuation of the curvilinear paths 3 of the stocks 1 and have a common center of curvature on the swivel base 8. Thereafter Platform 12 assembled with triple pods / 12 with lifting mechanisms 13 and supporting columns 14, 15, and 16 on the slip carts 4 is moved along the axis of the slipway m 2 by means of an actuator (not shown) until it is combined in terms of the supporting column 14 with a rotating base 8. After that, the supporting column 14 is lowered onto the swivel base 8, the platform 12 of the itepe is placed on the berth heifers 5 (see Fig. 3) and the berth carts 4 are removed from under the platform 12. Then, the platform 12 on the heatpans 5 is rotated by means of a drive (not shown) relative to the rotary base 8 until the holes between the vertical wall 6 and the flange of the platform 12 form a gap (see FIG. 4), after which the supporting columns 15 and 16 are lowered lifting mechanisms 13 to rest on the ground (see fkg. 5) and lift platform 12 above the floating device 9. The freed building trolleys 5 are taken out to the building 1, and floating craft 9 is deballaster; the lot and output are out of the platform 12 (see Fig 6, 7). After this, the platform is lowered from V1 to Fizz; Thus, the proposed device provides the descent on the eugu of a fully constructed self-elevating gyatform), simpler in design due to the lack of underwater rail tracks and carts, which will reduce its cost during construction and reduce operating costs. The invention The device for the descent sea self-n; Atforms on water containing a slipway, sleep: “e) an iMoJH1inline and curvilinear railing with railways that are located on them, as well as a curvature section of 1J1 & installed at the vertical wall of the KV piles B of the center of the radus of curvature of the curve. -: her way, characterized in that, in order to reduce the complexity of the descent pl. The device is assembled for water and simplifies the design, the device is equipped with underwater and coastal supports and has been installed on these OFiopaxs, while the section of the cree to the rail track is located on a pair of strapping vessels with curvilinear 1) railing tracks mi s horizontal plane.
