(54) LIFTING AND RATING DEVICE FOR LOWERING DEVICES FOR GVD-ACCESS STATIONS WITH FLOATING STABILIZERS

one

The invention relates to marine engineering and relates to the design of lifting and lowering devices for oijycKHbix hydroacoustic instruments with float stabilizers.

A lifting and lowering device for hydroacoustic stations with float stabilizers is known, comprising a support body with a vertical shaft in which a winch with a cable wire stored in a guide pulley and a docking device 1j are placed.

A disadvantage of the known device is damage to the lowering device.

The purpose of the invention is to prevent damage to the lowering device.

To achieve this goal, the device is equipped with an additional winch with a rope and a guide roller, and the docking device is made up of a crossmember and a carriage, the crossbar is fixed in the shaft and made with an inner cone, and the carriage is made with an outer cone, a central hole and the niche, while the carriage with the outer cone is coupled with the inner cone of the cross member and attached to the rope of the additional winch stored in the guide roller located in the mine

10 above the crossbar, and the cable through the lowering device located in the carriage niche is passed through the central opening of the carriage.

The drawing schematically shows

IS the proposed device.

The device comprises a carrying case 1 with a vertical shaft a in which a loopback 2 with a cable 3 is placed, which is stored in the guide pulley x 4.

In the case there is a docking fixture containing a cross member 5 with an internal cone 6 and a carriage

7 with an outer cone 8, a central hole 9 and a niche 10 in which the lowering device 11 is located, connected to the cable-cable 3. The lowering device 11 is made with float stabilizers 12. The carriage 7 is attached with the rope 13 of the additional winch 14 supplied in the guide roller 15, located in the mine and above the crossbar 5,

Lebeca 2 is installed on the serving ship (not shown.

The device works as follows.

In the initial position, the extrusion carriage 7 is free (under the force of gravity} it rests on the lowering device P, simultaneously holding the float stabilizers 12 in the required position due to a specially made sealing surface.

When the winch 14 and 2 are put into water, the cable 13 and the cable 3 and the lowering device 11 together with the carriage 7 are switched on to bleed out smoothly: without mutual disconnection, they are lowered down to full immersion. At a certain depth, the winch 2 is put on the brake, the downward movement stops a. The cage 7 is raised with the help of the winch 14 on the rope 13 to its original position.

When disconnecting the carriage 7 with the lowering device I1, the float stabilizers 12 under the influence of the lifting force are set to the working position and after turning on the winch 2 to bleed. The starting device 11 continues to move down to the required operating depth.

When sampling the lowering device 11, the operations are carried out in the reverse order.

Docking-undocking operations are carried out in a submerged position, which increases the failure-free operation of these operations and protects the lowering device from damage.
