Abstract

The invention relates to the mining industry and is intended for use in oil and gas wells using cable engineering. The goal is to increase the reliability of the device while at the same time simplifying the fastening of the rope. In case 1, at an angle to its axis, an inclined channel 4 is made. The latter is connected at one end with an axial channel 2, and the other with an annular cavity (CS) formed by the housing 1 and the sleeve 3 in working position. On the side surface of the latter, a longitudinal groove 5 is made, connected in working position with gearbox. Both channels 2, 4 (O (L 2 o with with o o to oo

The invention relates to the mining industry and is intended for use in oil and gas wells using cable engineering.

The aim of the invention is to increase the reliability of the device while at the same time simplifying the rope anchorage.

FIG. 1 shows the device before fixing the rope, general view; in fig. 2 - the same, after fixing the rope.

The device includes a housing 1 with an axial channel 2 and a sleeve 3. In the housing 1 at an angle to its axis there is an inclined channel 4 connected at one end with an axial channel 2 and the other with an annular cavity formed in the working position by the housing 1 and the sleeve 3. A longitudinal groove 5 is made on the lateral surface of the latter, which is connected in its working position with the annular cavity. Moreover, both channels (2 and 4) are made with the same diameter equal to the width of the annular cavity. The latter is made at least twice its width.

The device works as follows.

First, body 1 is screwed into sleeve 3, leaving the current thread un-wrapped so that the remaining end of the thread is not greater than the number of turns of rope 6, which is 5

Then, the rope 6 is passed through the axial channel 2 and the inclined channel 4 into the longitudinal groove 5 for the length of the winding part, screw the case -1 into the sleeve 3 until it stops. At the same time, the end of the rope 6 is wound on the lower end of the body 1 and clamped between the ends a and b (figure 2) of the case 1 and the sleeve 3 with the force necessary to securely fasten the rope 6. For additional insurance of the fastener, a lock nut 7 is provided (Figure 2) .
