RU2285653C2 - Log holding boom - Google Patents

Abstract

FIELD: wood floating.

SUBSTANCE: invention can be used in gathering and storing of wood lost at floating on water reservoirs. Proposed log holding boom is made up of assembly sections, each section consisting of box-section body with two pairs of rigidly secured crossmembers between which cylindrical pontoons are arranged on rotating axles. Connecting members are installed on free ends of extreme crossmembers, being made in form of cylindrical rings. Ends of crossmembers are arranged at equal distance from body at both sides of body. Connecting members made in form of rings are connected with rings of other sections by means of flexible ties for interconnecting sections in traveling position on the shore and in operating position in water to form cross holding boom.

EFFECT: simplified mounting of holding boom, reduced cost of its operation.

Description

The invention relates to the logging industry, in particular to timber rafting, and can also be used to collect emergency wood from reservoirs.

Known technical solutions (No. 201341, No. 1253917, No. 572416, No. 9662159) containing transverse and longitudinal floating parts of the sand, supports, shems.

Their main disadvantage is the high complexity during installation.

The closest in technical essence and the achieved effect is A. with. No. 1244070, selected by the author as a prototype and containing sections, lying and supports connected in series to each other.

The main disadvantage of this technical solution is the high complexity when installing zani on the reservoir.

The problem solved by the applicant is to reduce the complexity of the work during the installation of the company and in the process of its operation.

In the proposed technical solution, the pan is performed sectionally, and each section consists of a box-shaped body with two pairs of cross-members rigidly fixed on it, the ends of which are equally spaced from the body on both sides of it and between which cylindrical pontoons are placed on rotating axles, while on free the ends of the housing and the extreme cross members are installed connecting elements made in the form of cylindrical rings connected to the rings of other sections by means of flexible connections and with the possibility of connecting tions between a transport position on the shore relative to the long sides of the pontoons, and water - relatively short sides of the pontoons to form a transverse log boom.

Such a solution is proposed to be used for large reservoirs with low flow rates for collecting emergency wood in small volumes.

The combination of features set forth in the technical solution, allows to reduce the labor costs for installation and operation of the company. These signs have significant novelty and analogues that discredit the essence of the invention, we have not identified.

The invention is illustrated by drawings, where Fig. 1 shows a sectional view from above, Fig. 2 is a side view of a section, Fig. 3 is a front view of a section, Fig. 4 is a general view of connected sections in a transport position, Fig. 5 - a General view of the connected sections in working condition, Fig.6 is a General view of the harbor installed on the reservoir.

The present invention contains prefabricated sections, each of which consists of a box-shaped body 1 with two pairs of cross members 2 rigidly fixed on it, between which cylindrical pontoons 4 are placed on the rotating axles 3, connecting elements 5 are installed on the free ends of the housing 1 and extreme cross-pieces 2, made in the form of cylindrical rings, and the ends themselves are transverse equally spaced from the body on both sides of it.

The device operates as follows. Metal sections using connecting elements 5, through flexible connections (rope, chain) 6 connect the sections together relative to their long sides one after another on the shore, thus forming a transport structure (figure 4). In this case, the rotation of the cylindrical pontoons 4 can be carried out in the direction of the assembly structure. After that, this design is moved to the water area of the reservoir. On the water, by means of the connecting elements, the pontoons are again connected already to their relatively short sides, forming a transverse span (Fig. 5). Zapan connected to the coastal supports 7, is ready for operation (Fig.6).

In order to dismantle the harbor, it must be disconnected from the shore supports 7, and the pontoons should be connected to each other with respect to the long sides of their hulls. Using the traction body ashore, the structure is moved to land by means of rotating pontoons.

Using such a rebuild, it is possible to carry out the installation of sand in the water area of the reservoir. In addition, there is no need for ropes of large length and cross-section, as well as additional auxiliary equipment for installation work on the water.

This zanje, unlike the prototype, is intended for the collection of timber at large reservoirs, where timber and emergency timber enter it irregularly and in smaller volumes, and therefore, in this case, their long-term storage is not required.

Claims (1)

A forest holding pan containing prefabricated sections connected to shore supports, characterized in that each section consists of a box section body with two pairs of cross members rigidly fixed on it, the ends of which are equally spaced from the body on both sides of it and between which are placed on rotating axes cylindrical pontoons, with connecting elements made in the form of cylindrical rings connected to the rings of other sections by bending at the free ends of the housing and the extreme cross members x connections with the possibility of connecting the sections to each other in a transport position on the shore of the relatively long sides of the pontoons, and on the water, the relatively short sides of the pontoons with the formation of a transverse sand.
