Description

one

The invention relates to the logging industry and can be used to form river and lake bundles of logs on sorting and rafting raids.

Known rafting device, including raft chambers and mechanisms perepasovki raft chains with locks mounted on a movable bridge.

In order to simplify the release of the beam from the machine, in the proposed device, locks are installed on both sides of the bridge, each of which has vertical and horizontal guides with clamps of the position of the raft chains.

FIG. 1 schematically shows a rafting device; in fig. 2 - the mechanism of perepasovka raft chains with locks.

The rafting device consists of two rafting chambers A and B with a movable bridge 1, on which a repacking mechanism (grip) 2 with locks 3 mounted on both sides of the bridge is installed, and rafting chains 4 and 5 with spherical weights 6 and 7 at the ends.

The device works as follows.

In the initial position (see Fig. 1, a), the storage of raft chains 4 with a load occurs. B. To do this for a free-hanging end

the chain 4, the movable bridge 1 advances until the chain 4 enters the vertical guides 8 and the load 6 stops the clamp 9. With a further rise, the load 6

pushes the retainer 9, which rotates with the axis 10. Through the lever system consisting of the eyelet E connected to the axis 10, the pulley 12 and the lever 13, the rotation of the retainer 9 is transferred to the pusher 14. The latter, moving in the supports 15, compresses the spring 16. As soon as the weight 6 passes the latch 9 (see FIG. 2), the spring, uncoupling through the lever system, will turn the latch 9 to the initial position. In this case, the end of the chain 4 with a load of 6

it will not be able to go down because the latch 9 overlaps the vertical guides.

Upon further movement of bridge 1 (see Fig. 1.6) towards the raft chamber A, the load

6 moves along horizontal guides 17 and abuts against a lock located on the other side of the bridge (not shown in Fig. 2). Driving further, the bridge hits the second chain 5 with a load of 7 and stops

(see Fig. 1.6). The chain 4 is vented and logs are dropped on it. When the dumping of the forest is completed, the chain 5 with the load 7 rises and stores similarly to the chain 4 (see Fig. 2), but the load 7 does not move along horizontal guides, but is locked and remains in this position. Next, bridge 1 moves into chamber B (Fig. 1, b), while chain 6 is released. When the bridge 1 is moved to the raft chamber B, the wood is compressed and a beam 18 is formed. During compression and wrapping of the beam, the end of the chain 4 is throttled. load 5 falls out of the vertical guides, freeing the beam. Chain 4 rises and reorder occurs. After the beam has been set up in chain 5, bridge 1 moves to the raft chamber A.

beam 21 is formed and tied up (Fig. 1, d). Next, the raft cycle is repeated.

Subject invention

A rafting device for a raft of a log, including raft chambers and rafting chains with locks, mounted on a movable bridge, characterized in that, in order to simplify the release of the beam from the car, the device’s locks are installed on both sides of the bridge, each of them has vertical and horizontal guides with ratchet clamps.
