Description

one

The invention relates to industrial fisheries, is intended for laying cables on the winch drum during winding and can be applied, in particular, to fishing vessels in trawl winches designed for winding wafers, flexible distance tools, cables and net part of the trawl to the foot.

Devices of a similar purpose are known, comprising a carriage movably mounted on guides and movable parallel to the axis of the drum by means of a two-way screw, and two guide rollers mounted on the carriage.

However, such devices cannot be used for trawl winches, which are designed not only for winding wafers and cables, but also for flexible expansion means and the net part of the trawl to the bottom.

In the proposed device, the carriage is provided with two C-shaped brackets fixed on the common joint with the possibility of turning around it, and the guide rollers are mounted on the brackets.

Inside the carriage there is a traction body, for example, a hydraulic cylinder, and each bracket is connected by rods with its rod.

This embodiment of the device provides the possibility of winding on the drum also flexible distributing means and the net part of the trawl.

FIG. 1 schematically shows the proposed device for laying cables on the winch drum, front view; in fig. 2 - the same, side view, section and view along arrow L; in fig. 3 - the same, kinematic and electrical circuit.

The device contains a carriage /, with the help of rollers 2, planted on guides 3 and connected through basmak 4 fixed on it and cracker 5 with a two-way screw 6. The drive of the latter is equipped with a coupling 7 (see Fig. 3) ensuring its rotation in two modes - normal (when laying) and accelerated (when moving the carriage to the middle position).

On the carriage / common joint 8, two C-brackets 9 facing each other with an open part are fixed, each of which has a guide roller 10. The upper end of the roller 10 is fixed on the fixed hinge And, and the lower one on the spring-loaded pusher 12. С the back of each bracket is mounted microswitch 13, the button of which is installed in the zone of action of the pusher 12.

Inside the carriage 1 there is installed a traction organ-hydraulic cylinder 14, the shank 15 of which is connected with brackets 9 by means of t g 16. There is a rod at the junction of the rod with the rods

P, its ends are placed in the guide notches 18, 19 in the wall of the carriage 1.

Microswitches 13 are included in the control circuit of the device (see Fig. 3), which also contains the first latching relay 20, the latching pause relay between the lugs, hydro-electric mountains 22 and 23, roller dilution relay 24, microswitch 25, relay 26 the drive is turned off, the electromagnetic clutch 27 and the device 25. the account turns, laid "step by step.

To control the operation of the device in each fan, in front of the expansion boards, at equal distance from the boards, and one from the other, two bosses are secured.

The device works as follows.

Before starting the hauling of the trawl, it is in position I. The first boss, with the passage of the rollers 10, presses them, and the rollers diverge for some distance, and the pushers 12 act on the microswitches 13. A signal is applied to the relay 20, which closes the contacts of the relay and turns on the hydroelectric manipulator 22. The latter switches the clutch 7 with the help of a hydraulic cylinder, and the two-way screw 6 switches to an accelerated rotation mode. The carriage moves quickly until microswitch 25 is installed, set exactly in the center of the winch drum. In this case, through the relay 26, the electromagnetic clutch 27 is disconnected, and the carriage is stopped.

At the same time, the turn-counting device 28 is turned on, laid "step by step. Relay 21 has prepared relay 24. Then, when the second lug passes, relay 24 is given a second signal, the circuit opens, hydraulic manipulator 25 acts on the hydraulic cylinder 14. Rod 15 of the latter, moving up, pulls the brackets 9, thereby dissolving rollers 10 on a certain angle (see position P in Fig. 2). Simultaneously arrives

signal pa off device 28 counting turns, laid “step by step.

Flexible spacing boards are laid on the flanges of the 29 drums of the winch, forming a single surface on which the cables and the net part of the trawl are then wound. Before returning the trawl, the rollers 10 are in the diluted position. The drums are disinhibited, the drive is activated, and a sweep occurs from the drum of the netting part of the trawl, cables and flexible distance tools. After the latter have come off, the pressure in the hydraulic cylinder 14 is relieved, and the rollers 10 converge. After that, between the rollers passes

5 is the boss closest to the boards, which turns off the turn counting device 28. This device counts exactly as many turns as was wound during the hauling of the trawl. Then between the rollers 10 passes a friend.

0 boss, as a result of which the screw 6 is switched from the accelerated to the normal mode of rotation through the hydroelectric manipulator 22; at the same time, an electromagnetic clutch 27 is turned on.

5 warping for required length.
