Abstract

The invention relates to timber rafting, namely, devices for converting rafts from the pool to the pool. The purpose of the invention is to increase the convenience and reliability of operation. The device for transferring the floats 1 from the pool to the pool contains gable paths that include horizontal sections 3, 4, 5 connected by inclined sections 6, 7. On the routes there are sectional float carts 8. On sections 6, 7 in the pools additional ways are made, on which are equipped with skew platforms 10 with cantilever mating protrusions facing the watershed. The paths of the skid platforms 10 are reinforced on the basis of the paths below of the carts carrying carts on the outer side relative to them. Carts 8 are equipped with additional wheels. . The width of the track between the additional wheels is equal to the width of the track of the horizontal sections 3, 4 of the gable paths placed on the platform 10 and their cantilever protrusions. The upper along the cantilever mating protrusions are rounded along the mating radius with the plane of the bearing of the additional wheels of the carriage 8. 8 Il. § (L s

The invention relates to timber rafting, namely, devices for converting rafts from the pool to the pool.

The purpose of the invention is to increase the convenience and reliability of operation.

FIG. 1 shows a general view of the device; in fig. 2 is a plan view of the upstream and downstream, separated by a retaining structure; in fig. 3 is a cross section A-A in FIG. 1 braided platform and raft carts; in fig. 4 is a longitudinal section bb of FIG. 3 platform braids and floaters; in fig. 5 - scheme of approaching the flotilla carts on the skew platform; in fig. 6 is a top view of a skew platform; in fig. 7 is a scheme for introducing a raft to floaters; in fig. 8 - braid platform on inclined paths in isometric.

The device for transferring the rafts 1 from the bay to the bay through the supporting structure 2 contains gable paths including horizontal sections 3, 4 in the bay and 5 - on the watershed, interconnected by inclined sections 6, 7. Sectional float-carrying trolleys 8 are placed on the paths. Inclined sections 6, 7 in the pool are additional paths 9, on which slanting platforms 10 with cantilever mating protrusions 11 facing the watershed are installed. The paths of slanting platforms 10 are reinforced on the basis below sections 6 and 7 of the zhek, from the outside relative to their side.

The carrier trucks 8 are provided with additional wheels 12 (FIG. 3) for approaching the skidding platform along the cantilever projections 11 from track 6 or 7.

The track width (Excavation) (Fig. 3) between the additional wheels 12 is equal to the track width of the horizontal sections 3 and 4 (Fig. 6) of the gable paths placed on the braid of the platform 10 and their cantilever projections 11. Upper along the cantilevered mating the protrusions 11 are rounded along the radius 13 (FIG. 4) of the mating with the plane of supporting additional wheels 12 of the float carrier carriages 8 when the carts 8 move along inclined sections 6 and 7.

The device works as follows.

The platform 10, together with the float carriage 8 mounted on the horizontal section 3 on the platform 10, is in the initial position under water, in the pool, at the depth necessary for the passage of the tug and raft 1. The raft 1 is attached to the float carriage 8 with the help of tug 14 (Fig. 7) and secured to it (moored). After the departure of the tug 14, the platform 10, together with the float carrier 8 and the raft 1, moves up along

0

an additional inclined path 9 to the upper position, at which the tracks 3 on the platform 10 are located above the water level in the pool. Considering that extra

the track 9 of the skid platform 10 and the inclined tracks 6 are located at different levels, then for the exit (gathering) of the carriage carrier 8 from the horizontal section 3 on the skew platform 10 in the tail bay, cantilever bridging lugs 11 are provided, on which additional wheels 12 float the cart 8 and slides down the inclined path 6 (Fig. 5), and then moves to the horizontal section 5 at the watershed, which can serve as a traveling

a platform for two sets of carriages 8. Then, along inclined tracks 7 (Fig. 2), it moves downwards and enters the horizontal tracks 4 of the skid platform 10, which is located in a different bay. After that, the platform 10, along with the float carrier 8 and the raft 1, descend along the inclined path 9 under water. When the required depth has been reached, the raft 1 is hooked onto the tug, moored and taken out of the raft carrier. Then the float carriage 8 returns to the upstream of the next raft, and the cycle repeats.

In the event of the failure of one of the sections of the fleet bogie 8, it can be replaced by a backup section, after which the operation of the device continues.

0 With fluctuations in the water level in the pools, the skidding platform 10 can be moved higher or lower along inclined tracks 9 to ensure the normal entry of raft 1 into or with the raft carrier.
