Abstract

The invention relates to the forest industry, in particular to timber rafting, and can be used for coastal rafting and launching rafting units. The purpose of the invention is to provide the possibility of adjusting the dimensions of the rafting unit. The device comprises a trolley with racks 2 and 3 located on it. River racks 2 are installed with the possibility of tilting in one of the known methods. The shore posts are mounted on platform 4 and are connected to it by hinges 5 and 6. Platform 4 is mounted for movement along the direction of the longitudinal axis of the carriage. A rack 3 is articulated on a platform, with one of its hinges connected to the first rack by means of a cable block system with a lanyard 8 for simultaneous tilting of both racks. 1 il.

ways 11 (fig. 1). In this case, the pillars 2 and 3 are in the closed position, and the platform 4 is fixed on the base 1 in a position that provides the necessary distance B between the racks. The formed rafting unit together with the device is lowered into the water on an inclined track 11 by means of a drive 12 and a cable 13. When the rafting unit is immersed to a certain depth in the water, a 2 nd rack is used. The invention relates to the timber industry, and can be used for coastal rafts and rafting units rafting.

The purpose of the invention is to make it possible to adjust the dimensions of the rafting unit.

FIG. Figure 1 shows the proposed device, side view in the working position (racks are closed), the dotted lines indicate the possibility of moving some 10 are given by one of the known methods. When racks along the axis of the undercarriage; in fig. 2 - opening of the uprights 2, the tension in the cable 7 is sharply the same, but the stands in the open position. the folds 5 are reduced,

The device consists of a base 1 with the racks 3 under the action of the poles 2 and 3 placed on it. The river weights around the axis of the hinge 6 fold the racks 2 mounted with the possibility of simultaneously with the opening of the racks 2. When throwing one of the known methods . Further descent of the device into the water, the coastal posts 3 are installed on the wedge unit, which emerges and goes beyond the shape 4 and the barites of the device are connected to it with hinges. The device returns 5 and 6. The platform is located on the ground in its original position on the land driven

1 with the ability to move along its 12, with the pillars 2 rising in the longitudinal axis. In the working (closed) JQ position, the cable 7 is pulled, which by the hinge of the rack 3 is held back by the hinge returns the hinge 5, and consequently, 5, fixed by the cable 7 with the lanyard

8. Cable 7 through guide block 9 is connected to rack 2. Lanyard 8 provides the ability to adjust the length of cable 7 when the distance B between racks 25 is changed

2 and 3. The distance B between pillars 2 and 3 is changed by moving the platform 4 with coastal pillars 3 on it along the axis of the carriage at the base 1 and fixing it in the desired position,

for example, bolted. The position of the hinge 5, 30 of which are installed with the possibility of folding, with closed racks, adjusts with a lanyard 8, which is characterized in that

rack 3 in working position. Then the cycle repeats.

Claims (1)

Claims. A device for forming and launching rafting units, comprising inclined guides, on which a carriage mounted on its frame, is mounted with the possibility of reciprocating movement, one of so that when the tension of the cable 7 is relaxed (opening of the uprights 2), the hinge 5 folds down under the action of its own weight of the uprights 3. The base 1 is provided with wheel pairs 10, and the device as a whole moves along an inclined track 11 with the drive 12 and the cable 13 . The device works as follows. Shaping the rafting unit in 35 providing the possibility of adjusting the dimensions of the rafting unit, it is equipped with a platform located on the trolley frame mounted for movement in the direction of the trolley's longitudinal axis, and a friend of the pillars is hingedly mounted on this platform, one of its hinges is connected The device between the pillars 2 and 3 is manufactured by a lanyard for simultaneous folding of the land on the land in the upper part of the rail of both racks. ways 11 (fig. 1). In this case, the pillars 2 and 3 are in the closed position, and the platform 4 is fixed on the base 1 in a position that provides the necessary distance B between the racks. The formed rafting unit together with the device is lowered into the water along an inclined track 11 by means of an actuator 12 and a cable 13. When the rafting unit is immersed to a certain depth in the water, the pillars 2 fold in one of the known methods. When the racks 2 are opened, the tension in the cable 7 decreases sharply and the hinges 5 fold,  12, while the struts 2 are raised to work, the cable 7 is pulled, which returns the hinge 5, and hence  which is installed with the possibility of opening, characterized in that, with the aim of rack 3 in working position. Then the cycle repeats. Claims. A device for forming and launching rafting units, comprising inclined guides, on which a carriage mounted on its frame, is mounted with the possibility of reciprocating movement, one of which is installed with the possibility of opening, characterized in that, with the aim of providing the possibility of adjusting the dimensions of the rafting unit, it is equipped with a platform located on the trolley frame mounted for movement in the direction of the trolley's longitudinal axis, and a friend of the pillars is hingedly mounted on this platform, one of its hinges is connected
