Abstract

The invention relates to the forest industry, mainly to float raids and timber-handling bases engaged in unloading wood from water. To implement the method, the following technological equipment and facilities are necessary: forest 1 and auxiliary 2 trolleys, winch 3 with a cable-blocking system 4, basic 5 and intermediate 6 excavations, courtyard 7, slopes 8 and a rail track 9. At bundle 11, located in courtyard 7 , put on the slings 12, which zaproplivayu for logging truck 1, previously lowered into the water. The timber truck is pulled out of the water by a winch 3, the lines 12, tensioning, begin to move the beam along the rolls 8 to the intermediate overpass 6. Under the action of the force of the draw of the winch, the beam rises to the intermediate overpass. When the beam is on an intermediate overpass, the timber carrying truck is stopped, after which it is necessary to spawn, remove the sling from the raised beam and transfer them back to the yard 7.

Description

The invention relates to the forest industry, mainly to raid raids and timber transshipment bases engaged in unloading wood from water.

The aim of the invention is to increase the productivity of unloading timber.

FIG. 1 shows a diagram of the discharge of beams from the water according to the proposed method; figure 2 - stages of unloading beams; on fig.Z - the subsequent stages of unloading.

The implementation scheme of the proposed method shows a forest 1 and an auxiliary .2 trolley, a winch 3 with a cable system 4, a main 5 and an intermediate 6 trestle, a courtyard 7, slopes 8 and a rail track 9.

The timber logging truck should be equipped with a double-shouldered support 10, which can be rotated in a vertical plane on an axis fixed to the frame of the timber truck. The end of the long arm of the support is connected with a flexible thread to the frame of the trolley; a counterweight is placed on the short shoulder of the support. The proposed design of the stop allows it to always take a vertical position and rotate in the direction of the trolley surface.

Intermediate overpass should be installed near the water edge on an inclined section of the track. Moreover, the surface of the racks should be higher than the surface of the timber truck.

Slopes 8 are installed all the way from bridge 6 to a depth that provides a smooth entry of the beam.

The proposed method of unloading timber bundles from water is carried out as follows.

The bundle 11, located in the courtyard 7, is equipped with slings 12, which are placed behind the timber carrying cart 1 previously lowered into the water. The timber truck is pulled out of the water by a winch 3, the lines 12, tension, begin to move the beam along the rolls 8 to the intermediate overpass 6 (figure 2 a). Under the action of the force of the winch, the beam rises to an intermediate overpass. When the beam is on an intermediate overpass, the timber carrying truck is stopped (Fig. 2b), after which it is detached, the lines are removed from the newly raised beam and transferred back to the yard 7. The timber carrying truck is again lowered into the water. The pivot stop 10, meeting the beam on its way, is lowered onto the timber carrying truck and the latter freely passes under the beam just raised onto the intermediate overpass (Fig. 2 and).

After the passage of the intermediate overpass by the timber carrying cart, the swivel support 10 takes up ver5 under the action of the counterweight

ticking position, and the cart continues to be lowered into the water after the next m beam.

A bundle 13, next bound with slings, is grazed behind a timber carrying cart and the timber carrying cart is lifted out of the water with a winch. When the beam moves along the slopes, the pivot stop 10 contacts the previously raised beam 1 1 (Fig. 2 g) and begins to move it along the intermediate bridge until it is lowered onto the timber carrying truck (Fig. 3 d ). Simultaneously with the loading of the truck, the bundle 13, which is laid with slings over the truck, is dragged to the vacant place of the intermediate overpass. After the beam has been raised to the intermediate overpass, the cart is again stopped and the lines are removed and removed (Fig. 3e). The slings are transported to the courtyard, and the timber trolley loaded with a bundle of 0 is shifted to the main ramp 5.

The bundle is raised to the main overpass, simultaneously unloading the logging truck. The auxiliary carriage 2 is moved by a winch along the horizontal section 5 of the rail track 9 by means of the cable-block system 4, which in turn begins to move the unloaded logging cart 1 to the inclined section of the rail track. Then the auxiliary trolley is braked and the timber carrying trolley is moved to the intermediate overpass 6. The swivel support 10, meeting on its own way, the beam is lowered to the timber carrying trolley, and the latter passes freely under the beam previously left on the intermediate overpass (Fig. 2c). After the passage of the intermediate trestle bogie, the pivoting stop 10 under the action of the counterweight again takes up a vertical position, and the cart is lowered into the water after the next beam.

0 Hereinafter, the sequence of operations is repeated.
