Abstract

Usage: for fastening and extending ropes connecting movable objects with supports or objects between themselves. SUMMARY OF THE INVENTION: a device for fastening and releasing a carrier cable comprises a receiving unit having a body with a uncoupling drive, an axially spring-loaded stop and a spring-loaded sleeve with a groove for balls and a transmission unit located in it, on which on one side a conductor is fixed through the eye, and on the other hand, a rope is sealed, as well as equipped with a housing in which a ball lock is integrated in the form of an axially spring-loaded sleeve. New in the device for securing and extending the carrier cable is the implementation of a spring-loaded sleeve with a groove for balls in the receiving unit. 1 ill.

Description

The device relates to techniques for securing and extending ropes connecting movable objects to supports or objects to each other, for example, a ship with a ship, a ship with a berth, etc.

The purpose of the invention is to increase ease of use by providing automatic recoil of the rope when exceeding the permissible load on the latter.

The drawing shows the device in docked position.

The device for fastening and extending the carrier cable consists of two connecting nodes. The transmitted assembly with the supporting cable 1 attached thereto comprises a housing 2, in which an axially movable sleeve 4 having an outer groove for balls 5 and a cable conductor 6 is placed, which is spring-loaded with a spring 3.

The receiving unit includes a hollow body 7, which serves for directing and securing

a transmission connecting unit, and a spring-loaded stop 8 of a stop 9 connected to the handles 10 and designed to actuate the locking mechanism of the transmitting connecting unit, a sleeve 11. a spring-loaded spring 12 in which an annular groove for balls 5 is made.

The connection of the nodes is as follows.

A pull conductor 6 is passed into the receiving connector assembly. Upon subsequent tightening of the transmitted assembly to the receiving assembly, the shank of the sleeve 4 abuts against the spring-loaded stop 9, compressing the spring 8. As soon as the balls 5 of the transmitted assembly are opposite the annular groove of the receiving assembly, they will be pushed into this groove by the coupling assembly 4, which will move under action of a spring-loaded stop 9 of the receiving unit. There will be a docking of the receiving and transmitting nodes.

The nodes are disconnected as follows.

Handles 10. which are connected to the stop 9, move the latter, compressing the spring. The sleeve 4 of the transmitted assembly under the action of the spring 3 moves until the balls 5 penetrate into its outer groove. Balls 5 come out of the annular groove of the receiving unit and the nodes are disconnected.

The stiffness of the spring 3 of the transmitted node must be such that the sleeve 4 can be moved in the axial direction. The stiffness of the spring 8 of the receiving node must be such as to move the stop 9 and overcome the force of the spring 3 of the transmitted node.

When exceeding the allowable force in the carrier rope, the device operates as follows.

If there is a force in the carrier cable 1 of a more permissible housing 2 of the transmitted unit, it will begin to move, moving the sleeve 11, which compresses the spring 12 of the receiving unit (the stiffness of the spring 12 must be designed for the permissible load) Until the balls 5 are lowered into the groove of the transmitted node, exit the groove of the receiving node, as a result of which the device nodes will be disconnected.

The technical and economic efficiency of the proposed technical solution consists in providing automatic undocking of the receiving and transmitting nodes when the allowable force in the carrier cable is exceeded.

If the allowable force is exceeded in the carrier rope, it may break

or destruction of the receiving and transmitting units, which will entail the loss of the transferred cargo at sea, as well as the long-term repair of these units and other equipment working together with these units.
