SE468316B - Floating slipway and jetty - Google Patents

Abstract

The invention relates to a slipway which is made up of two pieces of load-bearing I-beams 1, reinforced with transverse I-beams, and U-beams, both longitudinal- running and transverse-running, are additionally arranged as support for timber 4, and at the start of the slipway a winch 17 is fitted and from the winch 17 wires run along the two I-beams 1 and over a cable wheel 19 mounted on the end extremity down to a respective block of concrete 16, which blocks of concrete are situated on the bottom, which means that the slope of the slipway in an underwater position is adjustable using the winch 17. <IMAGE>

Description

10 15 20 25 30 35 40 l Û i 2 A number of brackets 7 are the I-beams 1 for Slirstocken 8 holds the wood attached to attachment of a slip stick 8. in place.

Furthermore, an end stop 9 is mounted on the end of the grinding track.

Steel pipe overhead lines 10 have been installed along I- the beams 1 one to each tank 11. The air tanks 11 are open at the bottom to either top up or drop off water. To inflate the track's air tanks of 3 cubic meters (3000 liters) is recommended a compressor that gives at least 500 minute liters. The lifting capacity is 2.5 tonnes in addition to the track's own weight of 5 tons and a length of 20 meters.

The anchorage consists of 2 joints 13 of round steel.

The space that remains between the sanding track and the land is bridged with an articulated reinforced drive plate 14.

The air tanks 11 are regulated with ball valves 15, one for each tank, the ball valves are mounted at the beginning of the grinding path. With with the help of a compressor you can fill the tanks 11 with air for to raise the grinding path..To lower the grinding path is connected the air hose away from the ball valve 15 and the air is released the tank 11 whereupon the air tank 11 is filled with water and the web sinks ner.

A permanent winch 17 is mounted on each side of the I-beam 1 at the beginning of the grinding path. From the winch 17 a wire runs along with both I-beams 1 and at the end end is a pulley 19 mounted as the wires run over and continue down to var its concrete block 16 to be laid on. bottom.Slipbanans slope in underwater position is thus adjustable by means of 2 pcs wires attached to each its concrete lump. The wires adjusted from the shore with winch as. is placed. on each side at the beginning of the grinding wheel. Using the winch 17 you can thus raise and lower the grinding path. On shallower water you can instead of winches 17 with wires and concrete blocks 16 make two support legs 18 one on each side (see Fig. 7). The object of the invention is that but independent of water depth and bottom conditions can use it as a grinding wheel to pull up boats boats. When not in use as a grinding wheel, it can raised to a floating position and then used as a bridge 468 516 3 is thus insensitive to the ground condition, easy to service and repair.

The invention is not limited to the embodiments shown. len, but can be varied in a fertile way within the framework of the inventive concept, as defined by the following patent claims.

Claims (1)

468 316 10 15 20 25 30 35 4 PATENT CLAIMS A movable grinding track which at its inner end is pivotally attached to shore and intended for receiving and launching boat markers thereof, that is made up of two supporting I-beams (1) which are reinforced with transverse I-beams and further are U-beams arranged, both longitudinally and transversely, as support for timber (4) and at the beginning of the grinding path a winch is mounted (17) and from the winch (17) wires run along both I-beams (19) (16) which are located on the seabed (1) and over a rope wheel mounted at the end end to each more concrete block, which means that the slope of the track in the underwater position can be adjusted with the winch (17).
