(5t) DEVICE FOR FORMING. DAYS

I

The invention relates to devices for forming rafts and can be used in water transport of the forest to mechanize the process of forming raft sections.

A device for forming rafts containing a floating base in the form of pontoons, connected by a bridge, to which a hydraulically driven reversing device is hinged, is known, and a forming mechanism with devices for rigging and a 1J drive is installed on the pontoons.

A disadvantage of the known device is considerable laboriousness.

The purpose of the invention is to reduce the labor intensity.

The goal is achieved by the fact that the device for forming rafts is equipped with a carrying cable and guides mounted on the bridge perpendicular to its longitudinal axis with moving

, in them a slider made with a roller interacting with a carrying cable, wherein the turning-feeding device is made in the form of a lever mounted on the pontoon with arc-shaped grippers, and additional guides are made on the bridge with an additional slider moving in them, in which the hydraulic cylinder rods are fixed pivot drive driver 10.

FIG. 1 shows the proposed device, side view (without section of the formed raft); in fig. 2 - the same

ts plan view; in fig. 3 swivel attachment, a plan view (without an ejector actuator drive); in fig. 4 - the same, side view.

A device for forming rafts consists of a forming mechanism and a turning-feeding device. 3 9 The shaping mechanism, a place to form the raft, includes four pontoons 1, connected by two longitudinal 2 and two transverse bridges 3. On the front transverse bridge there are cargo devices and under the longitudinal bridges there are devices for feeding the tailor. 5 There are also portable mechanical winches for ut rigging (not shown), views 6 for bay loops, winches for controlling sections during its formation. In addition, a support roller 1 is placed on the shaping mechanism, through which the carrier cable 8 passes. The roller 7 is fixed, on a slider 9, which can be moved by a hydraulic cylinder 10 in guides 11 mounted on a front transverse bridge. A non-existent rope 8 in a river stream is fixed by bottom supports 12 (screw cores, etc.) through intermediate tiles floating on the surface of the water 1 3. On the deck of the pontoons 1 four papilonazh winches with sheymi and bark (not shown) are fixed. At the lower end of the pontoons 1, an anvil 15 is fixed, on which the tile of the pre-adhered oplotnik 16 rests to form section 17. The turning-feeding device is mounted on the pontoon 18, at the downstream corner of which an axis 19 is fastened passing through a vertical hinge 20 welded to the corner of the upper transom of the pontoon 1 To turn the pontoon 18, a hydraulic actuator is used which consists of two hydraulic cylinders 21 fastened with rods on a slider 22 moving in guides 23. The guides and one hydraulic cylinder are coaxially fixed to pontoon 1 and the other cylinder is pivotally attached to pontoon 3 through lever 2. By means of By placing such hydraulic cylinders, the desired pivot angle of the pontoon 18 is achieved with a smaller stroke of the hydraulic cylinder.

At the ends of the pontoon 18 are pivotally attached levers 25, to which arc-shaped grippers 27 are fastened via dampers 26. On hinged supports, a shield 28 is suspended at the side of the pontoon, which by means of a hydraulic actuator

A device for forming rafts containing a floating base in the form of pontoons connected by a bridge. There is a series of beams 29 in the zone forming section (the hydraulic actuator is not shown). The device operates to form rafts as follows. The papilonazh winch 1C device is installed against the courtyard 30 with bundles from which the section is formed. The upper arm 25 is located along the pontoon 18, the lower one perpendicular to it. A series of tufts 29 with a length equal to the width of the raft section are fed by cable accelerators 31 along the pontoon 18. The tufts in the row are previously connected to each other. When reaching the lower arm 25, the row of beams is braked by the hydraulic cylinder 32, stops, and the residual energy of the row is extinguished by the damper 26. At this time, the upper arm 25, which fixes the row of beams along the pontoon 18, is locked, the Pontoon with the row of beams is rotated by coal. After turning, the arms 25 are consumed, a shield of 28 rows of beams is fed into the zone forming section, where a rigging is put on it and it is connected to the section being formed. Pontoon 18 is reset to its original position, and the cycle is repeated again until the full set of sections. The parapets on the raft section are superimposed by the loading devices and k, the side rails unwind from view 6 as the section is extended. Onboard kits are mounted with mechanisms suspended under bridge 2. A longitudinal and transverse oplot is supplied by devices 5 of tiles 1b fixed to stops 15. The device moves along the yards 30 along rope 8 through roller 7 by means of winch winches that keep the device from the effect of reactive moments when spreading p yes beams. The use of the proposed device for forming rafts makes it much easier to carry out the heavy manual labor of workers-formers, to increase labor productivity in the formation of a section of rafts twice.

to which a hydraulically driven reversing device is pivotally attached, and a forming mechanism is installed on the pontoons with rigging devices and a drive, characterized in that, in order to reduce labor intensity, it is equipped with a carrying cable and mounted on the bridge perpendicular to its longitudinal axis moving with a slider moving in them, made with a roller interacting with a carrying cable, while the turning-feeding device is made in the form of a lever mounted on the pontoon with an arc different grippers, and on the bridge additional guides are made with an additional slider moving in them, in which the rods of the hydraulic cylinders of the drive-turning device drive are fastened.
