Description

one

The invention relates to shipbuilding, in particular, to devices, for automatically maintaining the equality of the lengths of the warp wires of two autonomous wire winch.

The known devices for automatically maintaining equal lengths of the warp of two autonomous rolling winchs include erasing, depositing and reading magnetic heads, which are sensors of synchronizing signals associated with high-frequency generators and a mechanism comparing the latter that acts on the drive of one of the winches.

A disadvantage of existing devices for automatically maintaining equal lengths of warps of two autonomous wire winchs is that they have a low accuracy of maintaining equality of warp lengths.

The purpose of the invention is to eliminate this drawback.

For this, erasing, depositing and reading magnetic heads are mounted in blocks located along the Waer Passage line. At the same time the erasing and spreading magnetic heads are connected to high-frequency generators, and the reading heads are connected to a matching mechanism.

The drawing schematically shows the proposed device.

Drum / winch 2 starboard and

The drum 3 of the left-side winch 4 is positioned on the flange 5. On the vanishing path 5 of the warp 5, there are blocks 6 containing an erasable magnetic head 7, a recording magnetic head 8 and a read magnetic head 9. The distances between the magnetic heads S and P are in blocks 6 of the right and left sides are the same. The read heads 9 are attached to the comparison mechanism / 6,

which acts on the governor // of the rotational speed of the engine 12 of one of the winches (for example, winch 4 of the left-hand side). The speed of rotation of the engine 13 of the winch 2 of the opposite side is set by the regulator

14. The type of regulators // and 14 depends on the type of drive of the winches 2 and 4. For the electric drive, the regulators //, 14 - controllers, for the hydraulic actuator - the performance regulators of hydraulic pumps (not shown in the fig.). Regulators are connected by channels 15 to the source of electricity or working fluid. High-frequency generators 16 and 17 are connected to erasing and applying magnetic heads.

Works the proposed device as follows. When bleeding from the drums /, 3, the warser 5 passes by the erase heads 7, which erase all previous marks, then past the recording heads 8, which simultaneously apply new

tags. Upon further movement of the warders 5, the tags are read by the heads 9. The pulses arising in the heads of the 9 reading marks enter the comparing mechanism 10. At the same time, the pulse from the reading head 9 of that side, the winch of which is controlled by the i4 adjuster, starts the generator 17 and on the 5% The heads 8 put the following marks. Comparison mechanism 10 accumulates the difference in arrival times of tags from heads 9. When the difference exceeds a predetermined amount, the mechanism generates and issues a control signal acting on the regulator 11, which changes the speed of rotation of the drum 3, thereby automatically maintaining equality of lengths waer. When sampling warders 5, the marks applied during etching are read by heads 9 and also arrive in mechanism 10, as in the etching of warders.

The proposed device at the same time can also serve as a counter for the length of the etched warp. To do this, it must be supplemented with elements that convert (taking into account the base of blocks 6) the number of counted marks into the length of etched or selected warders and with an indicator that allows visually determining this length.
