The invention relates to mountain promet, m. used in drilling rigs and reduces the time required to change the multiplicity of the pulley system. Tower 1 is equipped with crown-block 2 with pulleys (W). The latter are associated with those installed on the same axis W 6 of the traveling block 7 with the formation of a multi-string traveling attachment of variable multiplicity. On the edge of the working plate, adki 3, a hinge fixing unit 8 (П) 9 of a pulley rope 5 is installed, made in the form of a bracket mounted on wasps and Ш 10. The axis Ш 10 is located in a plane perpendicular to the plane Ш of the crown block 2, and Ш 10 - at the level of W 6. The fixing unit of the block 7 is a fixing surface (FP) in the form of linear depressions lying in the plane W of the block 7 and corresponding to the protrusions on the bearing elements of the block 7. On the latter there is an axis on which W 6 are mounted, however, the extreme ones are set console relative about the bearing elements. Unit 7 has protective covers, the end of which is made folding. To remove the P 9 of the rope 5, the block 7 is lowered to a convenient depth, the protective cover is folded back and the block 7 is pulled back into the OP area on the platform 3, aligning the protrusions and the OP recess. In this case, П 9 turns relative to extreme Ш 6, which ensures its exit from the stream. Then remove P 9 and transfer it to W 10 of node 8. 2 s. and 9 hp f-ly, 4 ill. so (L

The invention relates to the mining industry, in particular to devices for changing the multiplicity of the pulley system, and can be used in drilling rigs.

The purpose of the invention is to reduce the time spent on changing the multiplicity of the pulley system.

FIG. 1 shows a drill installation, general view; in fig. 2 - the traveling block mounted on the fixing surface; in fig. 3 is a top view of a suspended traveling block with a folded face protection cover; in fig. 4 - fixing surface on the working platform.

The drilling rig contains a tower 1 having crown blocks 2 with pulleys, a working platform 3 with a rotor 4 located in the center of it. Loops of a tallyan rope 5 connecting the shields of the crownblock 2 with pulleys 6 of a talley block 7 form a multi-jet traveling-block tooling. On the edge of the working platform 3 there is an assembly 8 for fixing the loop 9 of the pulley rope 5, made in the form of a bracket with an axle 10 installed on the axis. Moreover, the axis of the tongue 10 is located in a plane perpendicular to the pulleys of the crown block 2, and the pulley 10 is installed at the level of the shears 6 pulley block 7, fixed node 11 fixation pulley block.

The fixing unit 11 of the traveling block 7 is a fixed surface in the form of linear recesses corresponding to the protrusions 12 on the bearing elements 13 of the traveling block 7 located on its lateral surface. The linear depressions of the fixing surface are oriented in the plane of the tongs of the traveling block 7. In the bearing elements 13 of the traveling block 7, the axis 14 is fixed on which the slides 6 are mounted, and the outermost of them (shchivs 15) are mounted console relative to the carrying elements 13. The thrust block 7 has protective covers 16, among which the face covers 17 are made folding and mounted on hinges 18 with the possibility of lateral rotation relative to the suspended traveling block 7. The hook 19 is attached to the latter, and through the crown block 2 of the tower 1 t 21 of auxiliary winch 22. One end 5 wireline winch is fixed to the drill 23, the other - at node 24 of its attachment.

Changing the multiplicity of the pulley system on the rig is carried out in the following way.

To remove the hinge 9 of the pulley rope 5 from the console 15 mounted on the shchiva 15 axis, the traveling block 7 is lowered to a convenient height, the protective casing 17 is folded back by turning it on the hinges 18, then connecting the rope 21 to the hook 19, pulling the traveling block auxiliary winch 22 in the area of the locking surface on the working

platform 3 and lay it, combining the protrusions 12 and the linear grooves of the locking surface. When performing these operations, loop 9, in contrast to the loops on other shkivy, rotates freely relative to shkivya 15, thereby ensuring its free exit from the stream. The other loops, with a general weakening of the tension of the tackle rope, ensure that the corresponding pulleys fit the creeks due to the limited movement in the grooves of the protective covers 16,

Then, the loop 9 is removed from the pulley 15 and transferred to the knuckle 10 of the unit 8. When lifting the traveling block 7, the loop 9 pulls on the pulley 10 and is held while working with the traveling block.

The hinge 9 is mounted on the pulley 15 in reverse order.
