Description

Submitted 16 oct br

The proposed rafting machine for forming rafts of the “Ruff” type refers to double-acting machines with a movable bridge and is equipped with a floater.

The peculiarity of the machine is that the side faces of the bridge are made stepped, with the upper step designed to push the brush onto the flooded ends of the raft until the bottom step stops against the ends of the flooded ends of the previous brush.

The flooder is a bar moved by the front ends of the brush logs along inclined guides and submerging the rear ends of the brush logs with its own weight. Endless chains closed in a vertical plane are used to feed the binding material.

FIG. 1 shows a machine in plan, FIG. 2 is a longitudinal section of the machine along AB, FIG. 1 and FIG. 3 is a view along arrow B in FIG. one.

The machine is mounted on three bombs installed parallel to the flow, fastened by two cross-pieces 2. Below the longitudinal edges34

NOV at a distance of about 7 m is installed transverse bon 3, connected with one of the crossbars 2 by two trusses 4.

Along the boom 3 and across the boom 7, guides 14 are laid, along which the floating bridge 5 moves, pulling one or the other side over the flooded end of the raft.

The bridge is moved by a J8 winch mounted on it using ropes 79, which envelop the revolving blocks 20 installed on the trusses 4.

Parallel to the trusses 4 in the inclined guides 77 (Fig. 2), heavy shanks 7, which serve as floods for the tail brush of the raft, are mounted. The rods 7, under the action of their own weight, slipping or rolling in the guides 77, lie on the ends of the last brush, flooding them with their own weight.

The next brush, supplied by the bridge 5 and abutting with one end to the upper step 75 of the lateral face of the bridge, pushes the second end of the rod 7 to force it to rise along the guide and pass the front end of the brush over

previous brush constituting the tail of the raft.

The bridge is brought all the way down to the lower step 16 of its lateral face in the tail section of the already formed raft, after which the bridge returns back and rod 7, lowering, floods the end of the laid brush.

Further, the operation is repeated on the same or the other side.

The tie of the raft (Fig. 3) is produced by a wire coiled from the tails 11. The end of the wire is attached to an endless chain 13, the envelope of the blocks 72 installed at the exit point of the raft. Chains 13 traverse the wire around the raft, which makes it easier to pull.

At the place of release of the raft, rigid booms 8 (Fig. I) are installed on the cells 9 and core 10 in order to direct it across the flow.

Claims (3)

I. Double-acting railing machine for rafts of the type “Ruff, provided with flooding and movable bridge to form a raft, characterized in that the side faces of the bridge are stepped, the upper step 15 being designed to push the brush onto the flooded ends of the raft until it stops at the bottom step 16 into the ends of the flooded ends of the previous brush. 2. The machine according to claim 1, wherein the floater is a rod 7 moved by the front ends of the brush logs along inclined guides 17 and submerging the rear ends of the brush logs in water by its own weight during its reverse movement. 3. The machine according to claim I, characterized by the use of endlessly closed chains 13 in the vertical plane, located at the output end of the machine and intended to supply binding material.
