ANCHOR-BEARING BOAT Russian patent published in 2024 - IPC E01D15/14 B63B21/50 

FIELD: construction of bridges.

SUBSTANCE: invention relates to bridge construction and can be used in a system of transverse fastening when guiding a floating railway bridge with single or coupled anchors-suction cups. Anchor-bearing boat includes a pontoon boat consisting of pontoons, fore and aft beams rigidly connected to each other by means of bottom locks and deck devices, a pair of hinged towing beams connected to the fore and aft beams by a pin connection and a fixing stop plank, rolling path with a unit for cable deflection, resting on supports fixed by clamps, a carriage, a boom with a block cage with two blocks and a roller for the cable of the swingwinch with a crab, electrical unit, rain shed, cargo winch with cable, swingwinchs with cable and anchors, tackle consisting of fixed and movable cages enveloped by cables, working platforms, buoys, crabs, guard rail fixed on railing posts. Boom base is mounted on fore beams on boom position fixing pins and fixed by hinged bolts and clamping plates. Pedestal with a horizontal deflecting tackle block is installed on the fore beams; a roller is fixed to deflect the cable of the swingwinch with a crab during trawling of the submerged cable. On the aft beams there are couplers for fastening of cables of anchor winches of the held pontoons of the bridge, support brackets and frames for fastening of swingwinchs. Each pontoon is assembled from two sections of pontoon of floating railway bridge. In longitudinal direction external and internal pontoons relative to axis of symmetry of pontoon boat are combined with each other by means of platforms of sidewalk flooring with stops on height of bulwark of pontoons. Inner pontoons of pontoon boat are interconnected by means of fore and aft beams and supports for rolling path. Between the aft beams from above there is a connecting bridge fixed with the help of hinged bolts, on which there are two pedestals with horizontal deflecting blocks of the tackle, lugs for fastening the rolling path and for fastening the thimble with the cargo winch cable. Fore and aft beams are made in the form of hinged cantilever bridges with sledge-like contours on both sides, at each swingwinch there is a hawse for passage of an anchor cable, there are places for arrangement of anchor cranes. Block cage with two blocks, pedestal with horizontal deflecting block are fixed through flange connections. Rolling path is made of at least three sections connected to each other; at that, each section is made of H-beams. Block cage with two blocks is made hinged relative to the rolling path. Railing posts are fixed to bulwark of pontoon by means of clamping plates, on fore and aft beams railing posts are installed in inner bushings.

EFFECT: higher reliability of an anchor-bearing boat, reduced time of its installation.
