SU1204845A2 - Coupling link of flexible element - Google Patents

Description

The invention relates to mechanical engineering and can be used in rigging equipment, in particular in mooring lines.

The aim of the invention is to increase reliability by eliminating the separation of half-links during operation of the device.

FIG. 1 shows the connecting link assembly; in fig. 2 is the same, view A in FIG. one; in fig. 3 - the same, section BB in FIG. one.

The connecting link of the flexible element contains two C-shaped half-cavities 1 and 2, connected together by means of a sleeve 3 installed between the ends of the half-branch 2 and the axis 4 and the stepped pin 5, 1 pivotally connected with it, and one end is installed mounting ring 6. The stepped pin 5 is made with two radial protrusions - 7 and 8 on the side surface, the radial 7 being located at the input end of the pin and the radial) W of the protrusion 8 is located at the greater step 9 of the pin 5.

On the inner surface of the sleeve 3 is made of a longitudinal groove 10 corresponding to the radial protrusion 8, on the surface of the hole under 5, made

ZiO L

At the end of the half-joint 2, there is a through longitudinal groove 11 under the radial protrusion 7, and on the surface of the hole for the pin at the end of the half-joint 1 there is also a through longitudinal groove 12 corresponding to the radial protrusion 7. In this case the longitudinal groove 12 of the half-joint 1 is angled longitudinal groove 11 half-joint 2.

The pin 5 is spring-loaded in the axial direction by the spring 13.

The device works as follows.

When connecting the connecting link to the mooring unit, half-sleeve 1 is rotated by an angle corresponding to the angle between the slots 11 and 12, and the radial protrusion 7 is aligned with the longitudinal groove 12 of half-member 1. Then the pin 5 is pulled, squeezing the spring 13, so that the protrusion 7 is placed in the groove II of the half-joint 2, after which the half-sleeve 1 is folded back, the plant is put into the mooring unit, and the hemi-nodal 11 and 12 half-links 2 and 1 are combined.

Then pin 5 is released, the protrusion 7 of which passes through the heads 11 and 12 and turns out outside the half-link 1. Half-link 1 is turned to the initial position and, pulling the flexible element, the link is fixed.
