Description

The invention relates to the mechanization of timber rafting and can be used in the forest industry.

Known formati- cally the main rafts of rafts, including a self-propelled truck and a lifting device and a winch.

However, the well-known raft forwarder does not ensure the vypoleni forms of rotary heelings with any length of assortments and increase the reliability and safety of work.

In order to (carry out shaping operations at any length of assortments and improve: reliability and safety of work, the proposed raft maker is made with rousses and with four pairs of positioning pendulum rollers that form a window closed from iBicex for direction and control; "Aiata, while two vertical and lower horizontal rollers are installed: on fixed axles in the body of the roller, and the upper horizontal roller is mounted on the axis, fixed non-movably on the bracket. Not hinged om on the same case with pamoshyo eye lu n fingers.

FIG. 1 shows the proposed raft maker; in fig. 2 rolls with folding top roller, view in lay; in fig. 3 - rolls with otkid1ny upper roller (cuts but A - A n B - B).

Formal rafts consists of 113 self-propelled floating base 1, load-lifting device 2 in the form of a hydraulic rotary crane, two remote beams 3, designed for mounting a chassis-on-the-spot, out-1, two one-drum-like winches of 5 n Guide systems and |

The system of guide tracks consists of eight installed ino both sides of the rolls with zerpnmnn folding rolnokMN. The rails are tired; at such a distance from each other, that provide a weighting of logs with a length of 4, 5; 5.5 n 6.5 meters.

A roller wheel consists of a body 7, two vertically mounted rollers 8, freely rotating on vertical axes 9, n two horizontally installed rollers, the lower 10 of which freely sit 4ia axis 11, and the upper flap 12 freely sits on axis 13, fixed at the hinge bracket 14. The latter, with the help of the hub 15 and 16 of the hinge, with nominal 17 and 18 mounted on the housing 7 and with the necessary}, can be folded for free; bookmarks on top of trash aiata. At the end of the finger 18 is installed a handle 19, which serves to turn it. With the vertical position of the handle 19, the 1nggein 14 with a folding blister 12 is closed, i.e. it is in the horizontal and on the right and cannot be

tilted, with the handle positioned horizontally (turned 1 to 90 °), the bracket 14 with the folding roller 12 can be manually turned (Around ifflapHHpiHoro finger 18, i.e. it is in the open 1 position.

When the horizontal folding roller is closed horizontally, all four vertical and horizontal rollers form a window that is closed on all sides. A rope missed into this window cannot arbitrarily be released from the train. If it is necessary to quickly release the rope from the rouls or when skipping through the window of the rools attached to the rope of elements of the tailgate, whose dimensions exceed the dimensions of the window, 1 upper roller folds. For this, the handle 19 of the vertical (closed) position is turned to the horizontal (open) position.

Formovshik. Blots works as follows.

With coastal rigging 5Y with lifting devices. 2, the rigging is carried out in the cargo hold of the self-propelled floating base 1. Then the mold is transported by the rigging to the raft being formed and set parallel to the raft section. The remote beam 3 is turned into (working position and fixed. The lid is removed from view 4. By means of the load lifting device 2, the bay of the bay is put on the drum of view four. One end of the bay is fixed with a thin wire on the view 4, and the second is passed through the rollers of the remote beam 3 and zakrg -: l from pa raft.

After completely unwinding from view 4, the clamp fastens the end of the wire and breaks the thin wire and places it on the raft.

Two winches 5 are waggled on two non-riflend bridges, onboard kits, and longitudinal rigs are weighed and the parapets are drained: they are fed by one stern winch. Before the weaving is completed, the working ropes are rolled into the appropriate lengths of the assortment rolls 6. To do this, the handle 19 of the rolls is turned from the closed (vertical) position by 90 ° to the open (horizontal) position.

Subject and use of ip et te

A raft former, including self-propelled floating aircraft, a lifting device and a winch, characterized in that, in order to form a world. operations at any length of sports and increase the reliability and safety of work, he

made with rousses and with four pairs of pvppandic p1 arranged in pairs with each other rollers, forming a window on all sides for passing and guiding the rope, and this is two vertical and lower

horizontal horizontal rollers are mounted on non-movable axles x in the rousls body, and the upper horizontal roller is mounted on an axis fixed fixedly on a bracket hingedly mounted on the same body using protrusions and fingers.
