SU1257013A2 - Follow-up system for automatic casting of ship towing hook - Google Patents

Description

The invention relates to shipbuilding, in particular, to the following systems of automatic recoil of a towing hook of ships.

According to the main author. St. No. 380095 is known for the following system of automatic recoil of a towing hook of ships, which contains a roll-type contactor, which supplies a signal to an actuator stop, kinematically connected with a cable-blocking system with an automatic recoil mechanism of a tow hook, while the system is equipped with a power breaker that carries out a double a closure, made in the form of a lever, hingedly connected with a towing hook, and a spring-loaded plunger, kinematically interacting with the lever when the towing hook is deflected from ametralnoy plane of the ship.

The disadvantages of the known system are its large dimensions, insufficiently good conditions for its placement on the vessel and insufficient manufacturability of the assembly.

The aim of the invention is to reduce the size of the system, to improve the conditions of its placement on the vessel and the manufacturability of the assembly.

To achieve this goal, the follower system is provided with a waterproof case m, mounted on the hull structure under the towing hook, with the possibility of sliding the latter over the upper part of the waterproof case, and

11 of the spring-loaded plunger 12. The lever 9 is made in the form of a vertically located shaft 13, on which the upper arm 14 and the lower arm 15 are fixed one below the other. The hook 16 is pivotally attached to the upper arm 14, and the lower arm 15 acts on the sensitive elements 11 plunger 12. The lower part of the shaft 13, the lower shoulder 15, the sensing elements 11 and additional limit switches 5 and 6, are mounted in a single waterproof case 17, the upper part 18 of which simultaneously serves as a strap 19 for sliding the hook 16 along it relaying on board. A vertical shaft 13 is fixed to rotate in the upper support 20 mounted above the upper shoulder 14 and in the lower support 21 located between the shoulders 14 and 15 in the area of the upper part 18 of the housing 17. Access is provided to the inside of the housing 17 on its upper part 18 lid (not shown). Screws 22 and 23, which serve to adjust the sensitive elements 11 of the plunger 12, are brought out of the housing 17 to the outside.

The system works as follows.

When putting the hook 16 on board, the force in the towing cable creates a lateral component, which is dangerous in terms of tipping the vessel or flooding it. This force is constantly monitored by sensitive

the lever is a vertically razolo elements 11, to which it is transmitted from

hook 16 through the upper shoulder 14, the vertical shaft 13 and the lower shoulder 15. When the lateral force reaches a critical value and rolls the vessel at the limiting angle, the sensitive element and the end

spring-loaded plunger and end switches 35 or switch 5 or 6 will close the section of the electric shaft with one above the other upper and lower shoulders attached, with the upper arm being pivotally attached to the hook and the lower arm being installed with the possibility of acting on the followers with a trace The shoring system, wherein the lower part of the shaft, the lower shoulder, the spring-loaded plunger and the end ejectors are mounted in said waterproof housing.

circuit 8, while the roll sensor 1 also works and the limit switch 2 or 3 will close its part of the electrical circuit 8.

The dangerous situation for the vessel is characterized by a critical angle of heel and a critical lateral force acting in the direction of the heel, therefore the electrical circuit 8 is closed by limit switches 2 and 5 or 3 and 6, depending on which

The system contains a sensor 1 roll, vy-45 board simultaneously acts force and roll.

When the circuit is closed, the actuating element 7 is triggered, the hook 16 is opened, dropping the rope, thereby removing the lateral tilting force, and the vessel is leveled. The proposed tracking system, compared with the known one, has smaller dimensions, improved conditions for its placement on the vessel and improved assembly technology.

Complete in the form of a tandem, interacting with one of the limit switches 2 and 3, force sensor 4, closing one of the additional limit switches 5 and 6, actuator 7 and electrical circuit 8. Force sensor 4 consists of a lever 9, the swing axis 10 located in the ship's DP, and sensitive elements

11 of the spring-loaded plunger 12. The lever 9 is made in the form of a vertically located shaft 13, on which the upper arm 14 and the lower arm 15 are fixed one below the other. The hook 16 is pivotally attached to the upper arm 14, and the lower arm 15 acts on the sensitive elements 11 plunger 12. The lower part of the shaft 13, the lower shoulder 15, the sensing elements 11 and additional limit switches 5 and 6, are mounted in a single waterproof case 17, the upper part 18 of which simultaneously serves as a strap 19 for sliding the hook 16 along it relaying on board. A vertical shaft 13 is fixed to rotate in the upper support 20 mounted above the upper shoulder 14 and in the lower support 21 located between the shoulders 14 and 15 in the area of the upper part 18 of the housing 17. Access is provided to the inside of the housing 17 on its upper part 18 lid (not shown). Screws 22 and 23, which serve to adjust the sensitive elements 11 of the plunger 12, are brought out of the housing 17 to the outside.
