SU20541A1 - Floating device for rafting logs - Google Patents

Description

The device for rafting logs, without the use of wood-leaved wood for this purpose, consists of two pontoons, interconnected with a lattice structure, equipped with mobile racks for squeezing a raft assembled between non-rafts. After assembling the nlota and wrapping it with chains previously laid between the nonon, the mobile side posts are moved away and the pontoons filled with water are immersed in water, leaving the assembled raft afloat.

In FIG. 1 is a front view of a floating device; FIG. 2 is the same, top view; FIG. 3 is a front view of the device during its loading with logs; FIG. 4-part of a modified device mobile racks.

The floating device (Figs. 1 and 2) consists of two nononts 3-5, connected to each other along the bottom by means of transverse beams 1, interconnected by points with points 2. Racks 4 are attached to the pontoons, connected to each other along the top by beams 5, between which are installed longitudinal links 6. At a short distance from the pontoons 3-5, from the inner side of the chamber 1–2–4–3–6 there are racks 7, rotating on hinges 8, attached to beams 5, and held in the vertical position the appropriate fixtures 10 or connected with 25 hinged levers with t goy 26 (FIG. 4). In the lower part of one of the pontoons, a water inlet 12 is arranged, closed by a valve, controlled by a corresponding mechanism 13, and both pontoons are connected downstream by two pipes 11, as a result of which

they always maintain the same water level. If necessary, several such water openings can be arranged. For pumping out water, a pump 15 is used, which inundates water to a pipe 14, which reaches to the bottom of the ionon, and is driven by some engine, for example, an electric motor 16. But when pulled onto a log device, it is gradually immersed in water, and the depth The load can be adjusted by letting in water through the opening 12 or pumping out by means of the pump 15. After loading the fixture with the logs 8, (Fig. 3), the water is pumped out of the pontoons so that the fixture rises together with the logs and the logs are tight. pressed against each other. The logs are then connected with the help of a pre-laid on the nlatform and hung to the beams 6 chains or ropes 19, equipped with appropriate tensioning devices; To impart the rigidity to the whole system, the suspensions 21 serve. After fastened logs, the racks 7 are folded and water is let in the pontoons, as a result of which both pontoons are lowered and the finished raft of logs 18 remains afloat and can be removed. After installing racks 7 in the original vertical position and pumping water from the pontoons, you can nstupit to build a new raft.

The subject of the patent.

A nlowway device for rafting logs connected by chains or cables, equipped with water filled as ballast pontoons, characterized in that the pontoons 5-5, cb -. howling between each other with a lattice design of 1–2–4–5–6 (figs, 1 and 2), forming a camera loaded with logs, turning sleep & veins (figs. 1 and 2) or retractable racks 7,

the lateral log supports, which stands, on binding the logs to the Raft, fold or move away to allow the raft to float when the device is submerged to the proper depth by simply filling the pontoons with water.
