Description

one

The invention relates to shipbuilding, in particular to devices for fastening and quick release of ropes.

A rope stopper is known, comprising a stationary housing with two drums having grooves 1 on the outer surface.

The disadvantage of this device is the design complexity and low reliability.

The closest technical solution to the invention is a rope securing and quick release device comprising a base and a holding member 2 mounted thereon.

The disadvantage of this device is the complexity of the design and the unsafe handling.

The purpose of the invention is to simplify the fixing of the end of the rope and its recoil and increase the safety of work.

This goal is achieved by the fact that the device is equipped with a conical chuck mounted on a rope, the retaining element being designed as hingedly interconnected bodies and caps, the mating surfaces of which form a conical nest cooperating with the conical chuck, while a swivel lever is mounted on the basis of the hingedly mounted with a cam and figurnu a lath.

FIG. 1 shows the device for fastening and quick recoil of the rope, general view; in fig. 2 shows section A-A in FIG. 1 (the dot-dotted line shows the initial position of the rope); in fig. 3 shows a section BB in FIG. one.

The fixing and recoil device of the rope consists of a body 1 and a hinged latch 2 connected with it, the mating surfaces of which are made in steps, in the form of a ledge 3 and form a conical socket 4, the axis of which is parallel to the plane of the mating surfaces. The taper of the socket 4 corresponds to the taper of the cartridge 5, fixed at the end of the rope 6. The transitions from the conical surface of the socket 4 to the end walls of the housing 1 and the cover 2 are made 20 rounded. The vertical portion of the ledge 3 is made with a tilt in the direction of the force. A handle 7 is mounted on the lid 2. On the casing 1 there is a hinged figurna strap 8 and a pivot arm 9 made with the cam 10 on the hinge side. In the closed position of the figurnal device, the strap 8 adjoins one cover 2 inclined to the inclined surface 11, and the cutout 12 on the other hand contacts the cam 10 of the lever 9. The fixing and quick recoil device of the rope works as follows. The end of the rope 6 attached to another vessel or a buried object, such as a bark, is passed through the conical socket 4 of the device. To do this, the lever 9 is folded up, the cam 10 of which comes out and § contacts with the notch 12 of the figured bar 8, then the lid 2 rises by the handle 7 and the rope 6 is placed in the socket 4 6. After the rope 6 is laid, the lid 2 lowers and enters with its surface 3 contact with the mating surface of the housing 1. The figured bar 8 is turned, pressed against the surface 11 of the cover 2 and fixed in this position by the cam 10 by turning the lever 9. The remaining part of the rope 6 with the cartridge 5 is stored on the vessel, for example, a view. When recovered, the core of the rope 6, under the influence of its weight, winds up from the view and passes through the conical nest 4, fulfilled ush, its function as a clouse. The rounded edges of the conical nest 4 prevent damage to the rope 6. After the rope 6 leaves the view, the conical cartridge 5 is wedged in the nest 4. The axial force transmitted by the cable 6 through the cartridge 5 is perceived by the conical nest 4 and the ledge 3. The bar 8 fixed by the cam 10 of the lever 9 , does not allow the cover 2 to open under the pressure of the cartridge 5 on the conical surface of the socket 4. To release the fixed cable 6, it is necessary to turn the lever 9 so that the cam 10 comes out of contact with the figured strip 8, after which it is not Jet prevent the disclosure of the cover 2 under the action of pressure of the cartridge 5. The lid 2 is opened and the rope 6 is released from the fastening. The inclination of the vertical portion of the ledge 3 prevents the cover 2 from jamming on the body 1 as a result of the axial tension force of the rope 6. When the end of the rope 6 is recovered with an increase in the angle of rotation of the lever 9, the force on the handle of the lever 2 increases dramatically, transmitted to the cam 10 by the figured bar 8. In order to limit the forces on the lever 9 lever, the length of the notch 12 of the figure bar 8 is chosen such that the cam 10 comes out of contact with the plate 8 before the start of a sharp increase in the reaction force shoulder of the cover 2. Surface 11 Made with a tilt relative to the vertical plane, reducing the force transmitted by the lid 2 through the figured bar 8 to the cam 10 of the lever 9. The use of the proposed fixing device and quick recoil of the rope, compared with the similar devices used, simplifies fixing the end of the rope and its quick return, improves safety when working. This device makes it possible not to secure in advance the end of the tow or root cable as in conventional towing or main devices, which allows for the compact storage of the rope passed through this device. Combining in this device the functions of a lock and a device for securing and releasing the rope reduces the space occupied by the device on the ship's deck. This device allows the use of remote control recoil rope. Claims Anchoring device and quick recoil of a rope, comprising a base and a holding member mounted thereon, characterized in that, in order to simplify fixing of the end of the rope and its recoil and to improve work safety, it is provided with a conical cartridge mounted on the rope, the holding member being in the form of a body and cover pivotally interconnected, the mating surfaces of which form a conical socket interacting with a conical cartridge, while at the base of an articulated cm ntirovan pivoting lever with a cam, and curly bracket.
