Abstract

SUMMARY OF THE INVENTION: In the through grooves of the housing, branches of two rope loops are fixed, fixed by a jamming element. Through grooves are made with a jumper between them. One of the grooves is made conical and with an ellipsoidal cross-section along the height of the bar. The jamming element is made in the form of a tear with a taper equal to the taper of the conical hole. The jamming element is placed in said hole with the same taper direction between the branches of the additional rope loop. The jamming element is made with a latch. The latch is made in the form of a flexible element with loops at both ends. One loop is located with the coverage of the main loop of the rope. Another loop is located with the coverage of the jamming element. 1 s.p. f-ly, 4 ill.

Description

The invention relates to general mechanical engineering, in particular devices and can be used in various load-lifting devices, rigging, as well as for fastening machine elements, and equipment where it is necessary to seal the fastening of the end of the rope.

The aim of the invention is to ensure high reliability of the fastening of the end of the rope, both in static and in working order, reducing the complexity of the end) operations on the termination of the loop of the rope due to the ease of assembly and disassembly of the connection.

This goal is achieved by the fact that the end-of-termination of the fastening of the loop- or of the rope contains a body in the form of a bar with through grooves for accommodating two counter loops of the rope in them, a wedge element made in the form of a tear and a latch. Moreover, one groove in the plank is made cylindrical, and the other groove is made conical and with an ellipsoidal cross-section along the height of the plank, a tear-shaped jamming element is made with a taper equal to the taper of the conical groove, and placed in it in the same taper direction and with a gap for placing between them a loop of the rope facing toward the extension of the cone. The latch is made in the form of a flexible element with a loop at one end for gripping a branch of a rope loop over a cylindrical groove and with a loop at the other end of the flexible element fixed in the hole of the jamming element.

Thus, the claimed design of the end termination of the rope loop has the following essential features:

: - the body is made in the form of a strip with through grooves to accommodate two oncoming loops of the rope, one of which

the groove is cylindrical (for introducing a long branch of the rope), and the second groove is tapered with an ellipsoidal cross-section along the height of the strip (to accommodate the loop of the rope with the jamming element). This allows for a compact design; .

- a long branch of the loop is introduced into the cylindrical groove, which makes it possible to fix the strap on the rope and, in combination with the conical groove, form a loop with regulation of its dimensions by moving the strap along the long branch of the rope;

- a conical groove with an ellipsoidal cross-section is made with a slope along the major axis of the ellipse with parallel walls along the minor axis, which in combination with. a tear-shaped jamming element provides reliable locking of the rope loop by self-hardening under tension of a long branch of the rope and eliminates the possibility of this loop slipping through a narrow part of the groove;

- the latch is made in the form of a flexible element with a loop at one end to capture the long branch of the rope loop above the cylindrical groove and with a loop at the other end of the flexible element fixed in the hole of the jamming element, which prevents the jamming element from falling out and the loop from the conical groove of the strip when loosening stretching the long branch. This prevents accidents by re-tensioning the long branch of the rope.

In FIG. 1 shows the end closure of a rope loop; in FIG. 2 and 3 - bar; in FIG. 4-jamming element.

The end closure of the rope loop comprises a strip 1 with a cylindrical groove 2 for introducing the long branch of the loop 3 and a conical groove 4 with an ellipsoid cross-section to accommodate the oncoming loop 7, the short branch 5 of the rope and the jamming element 6. To prevent the jamming element 6 and loop 7 from falling out groove 4 and, accordingly, to open the end seal, there is a latch 8 made in the form of a flexible element with a loop 9 for gripping a long branch 3 and a loop 10 for fixing in the hole 11 of the jamming element 6..

When terminating the loop of the rope, for example, to secure the rope to the equipment, the long branch 3 of the rope is inserted into the cylindrical groove 2 of the strap 1. The short branch 5 of the rope covers the element 12 and is inserted into the conical groove 4 from the narrow part thereof. Derived from the wide part of the conical groove is short

branch 5 is bent and its end is inserted back into the wide part of the conical groove 4 and is led out through its narrow part, thereby forming the oncoming loop 7. In this loop

the jamming element 6 is inserted. By pulling up the length of the branch 3 and moving the strip 1 along it, the counter loop 7 with the jamming element 6 is tightened into the conical groove 4, and the whole end seal

pulled to the element of equipment 12,

The latch 8 is fixed by its loop 10

on loop 7 and jamming element 6

through the hole 11, and loop 9 is fixed

- on a long branch of 3 ropes near strap 1.

5 In this way, the end seal of the mount is ready for use. Moreover, the greater the tension force of the rope, the stronger the tightening of the jamming element and, accordingly, the friction force in the conical groove between

0 rope, groove walls and jamming element. A narrow part 7 does not jump out of the loop 7 and the jamming element 6 from the groove 4. This achieves high reliability of the end closure of the rope loop.

5 If it is necessary to disassemble, the long branch 3 is loosened, the bar is withdrawn from the equipment element 12 and the short branch 5 is fed into the conical groove 4 of the bar 1 until the loop 7 and the jammed
