Description

In the proposed adaptation to the vessel for catching sunken logs, a rigid swiveling frame is installed on the bow of the vessel, the lower end of which is let into the water and the grab of the logs is equipped with levers with teeth.

In another form of implementation, in order to change the depth of immersion of the arms, the frame is made sliding between vertical guides attached to the vessel.

In FIG. 1 is a side view of a wreck logging vessel; FIG. 2 - view from above; FIG. 3-side view of the device in a different form; FIG. 4 - view it from above. ,

A rivet frame / is installed in the forward part of the vessel, rotatable about axis 2 (Figs. 1, 2). On the lower end of water, lowered on the hinge 9 with limited rotation, are attached levers 5 equipped with teeth to grip logs 8. Lifting is carried out from the steam swan 4 through the cable 6 rotating the frame / about the axis 2 and setting it from position B i position A shown in FIG. 1 dotted line. To keep the levers 5 in the horizontal position, the latter are connected to the cable 7 supporting them using the drum 5i. The fixture can work at the maximum depth depending on the length of the frame / and in the smallest places, as indicated on the drawing in position A and above .

In another form, in order to change the depths of the dives of the levers 5, the frame 7 slides in the vertical direction along the JO guides mounted on the frame JJ fixedly fixed on the bow of the vessel. The lifting of the levers 5, together with the caught log 8, is carried out with the help of a cable 6, thrown over the block 72 ,, and the winch 4.

The subject of the invention 1. The adaptation to the vessel for catching sunken logs, characterized by the use of a rigid frame 7 installed in the bow of the vessel and siabny at the lower end, lowered entry
