Abstract

FIELD: forestry.

SUBSTANCE: invention relates to forest industry, in particular, at initial rafting on rivers with small and medium depths of round timber to consumers from hard-to-reach redundant regions of the country. Proposed flat ridge unit is made in the form of levelled round timber, tightened by two straps in the form of flexible threads, on free ends of which cargo hinges are rigidly fixed. Straps are furnished with rectangular steel cases with three through holes to accommodate plastic clamps-braces equipped with locking devices and covering each timber individually.

EFFECT: invention simplifies the process of forming a flat raft unit, as well as improves its transport characteristics at initial alloy along rivers with low depths.

Description

The present invention relates to the forest industry, in particular with the initial rafting along rivers with small and medium depths of round timber to consumers from hard-to-reach forest regions of the country.

Known technical solutions (Patent No. 2187442, Patent No. 2177436, Patent No. 2164467, Patent No. 21191949), containing rows of round timber, arranged in tiers perpendicular to each other, united by frames for rows made of logs with holes for connecting timber, as well as frames with flexible ties provided with lower harnesses and vertical ties. In addition, the invention is known (patent No. 2043255), containing round timber of limited buoyancy, stacked in several rows, packages of round timber of increased buoyancy, equipped with strapping, while the timber of the inner rows abut in the package of timber, which are interconnected by flexible strapping, covering the outside round timber of limited buoyancy.

The closest in technical essence is the device selected by the authors as an analogue (patent No. 2520655 B63B 35/62) containing an aligned row of round timber pulled together by two flexible strapping and vertical ties, and the strapping is made in the form of a flexible thread, characterized in that cargo loops with clamps are installed on the middle part of the flexible thread and at its free ends, while vertical ties made of a rectangular steel housing, which is made with a lower through hole, through which a vertical screed is movably mounted on the lower branch of the flexible thread, with an upper hole, a vertical groove and two lateral horizontal grooves made on opposite sides of the body plates, for winding and fixing the upper branch of the flexible thread in this case, both branches of the flexible thread cover piecewise round timber, which are locked at the ends of the thread with a latch. The disadvantages of this device are: the complexity of the design of a flat raft unit, high technical and economic costs, due to the use of a large amount of fixing material, a significant length of time for its disbanding on the raids of the float.

The technical result is an improvement in the transport characteristics of the raft unit, simplification of the design, and expansion of technological capabilities when rafting on rafts of the float.

The technical result is achieved by the fact that the proposed flat raft unit consists of aligned round timber pulled together by two strands made in the form of flexible threads on the free ends of which cargo loops are rigidly fixed, while sleeves in the form of a rectangular steel body with three through holes are installed on the strands in which plastic tie clamps are mounted, equipped with locking devices and covering each timber individually.

The proposed device is illustrated by drawings, where figure 1 shows a flat raft unit - side view; in FIG. 2 shows a method of fastening round timber - side view; in FIG. 3 - the same, top view; in FIG. 4 shows a tape of flat raft units.

The proposed flat raft unit consists of aligned round timber 1, tightened by two strands 2, made in the form of flexible threads, on the free ends of which cargo loops 3 are rigidly fixed, while sleeves 4 in the form of a rectangular steel case with three through holes 5 are installed on the strands 6,7, in which are mounted plastic clamps ties 8, equipped with locking devices 9 and covering each timber individually.

A flat raft unit is formed on the shore of a riverine forestry warehouse as follows. Along the gaskets laid on the ground, two strands 2 are laid parallel to each other, with pre-mounted sleeves 4 with a length of a smaller diameter of the logs. Moreover, plastic clamps-ties are installed in the sleeve 8. With a tower crane, a bundle of round timber is laid on gaskets, which loaders roll into a single-row brush of logs to cargo loops 3. Then each log laid on the bindings is manually pulled together with plastic clamps and secured with locking devices. With this method of strapping, the possibility of falling of logs from a flat raft unit is excluded, due to the fact that each log is rigidly fixed. Flat raft unit ready for rafting.

With a tower crane, the raft unit is reloaded from the riverine warehouse to the water-alloy river. On the water, raft units can be combined into ribbons or river rafts for towing by the alloy fleet to consumers (Fig. 4).

As a result of the use of this device, the process of forming a flat raft unit is simplified, and its transport characteristics are improved during initial alloying along rivers with shallow depths.

Claims (1)

A flat raft unit having a leveled row of round timber containing two strands made in the form of flexible threads, the cargo ends are rigidly fixed to the free ends, and sleeves in the form of a rectangular steel case, characterized in that the said sleeves are made with three through holes, into which plastic tie clamps are mounted, equipped with locking devices and covering each timber individually.
