Abstract

BACKGROUND OF THE INVENTION The invention relates to mechanized fasteners, improves performance, and improves maintainability. The device includes an overlap 1, a supra-rack mount 2 connected to it with a spherical surface and a strut with a rod 5 cooperating with the latter. In the opening of the overlap 1 a rotatable sleeve 6 is installed with protrusions 7 resting on the protrusions 8. A two-stage cylindrical groove is made on the rod 5. A cylindrical groove (P) 9 (a step of smaller diameter) is made with a groove 10 for an annular lock 11. Between P 9 and 12 (a step of a larger diameter) there is a tapered surface 13 and a protrusion 14 for a remote ring (DC) 15. Between the annular lock 11 and DK 15 is mounted for movement along P 9 supporting ring head 16. It is made with face cylindrical bore 17 for fixing ring lock 11. The depth of bore 17 is equal to the height of DK 15. When assembling, a rotary sleeve 6 is installed on the rod 5 of the stand, DK 15, and on P 9 - to oltsev head 16. An annular lock 11 is inserted into the groove 10, and the head 16 rises along the П 9 against the stop into the lock 11, closing it with a bore 17. Then the DC 15 moves into the gap between the annular head 16 and the protrusion 14. The sleeve 6 is inserted into the apertures 1 until its projections 7 align with the projections 8. The device is disassembled in reverse order. 2 Il.

Description

Rie.1

The invention relates to the fastening of a slaughter for the extraction of minerals by an underground method, namely to mechanized crepes and cleansing faces.

The aim of the invention is to improve performance and improve maintainability.

FIG. 1 shows a device for connecting a ceiling with a support of a shaft support section; in fig. 2 is a section A-A in FIG. one.

The device consists of a 1c overlap with an uprights support 2 having a spherical surface 3 rigidly attached to the floor below and in contact with the spherical recess 4 of the rod 5 of the support stand. In the opening 1, a sleeve 6 is installed with segment protrusions 7 resting on the projections 8 of the overlap I. On the rod 5 there is a two-stage cylindrical groove comprising a cylindrical groove 9 (smaller diameter stage) with a groove 10 under the ring lock 11 and a cylindrical groove 12 (a step of larger diameter). Between the grooves 9 and 12 are placed a conical surface 13 and a protrusion 14 for the remote ring 15. The conical surface 13 and a cylindrical groove 12 are designed to displace the remote ring 15 during installation work. On the cylindrical bore 9 of the rod 5 between the ring lock 11 and the ring 15, a supporting ring head 16 is mounted for movement along it, in which an end cylindrical bore 17 is made from the side of the overlap for fixing the ring lock 11. In the overlap 1, the supporting ring head 16 can contact the surface 18 with the surface 19 of the sleeve 6 (in Fig. 1, the contact is not shown).

The depth of the bore 17 is equal to the height of the remote ring 15.

When assembling the device, a rotary sleeve 6 is installed on the rod 5 of the stand, a distance ring 15 is placed on the cylindrical groove 12 of the stem, and an annular head 6 is placed on the cylindrical groove 9. An annular lock 11 is placed in the groove 10, then the ring head 16 rises along a cylindrical groove 9 up to the stop in the ring lock 11, while closing it with the bore 17. From the cylindrical groove 12, the distance ring 15 moves into the resulting gap between the supporting annular head 16 and the protrusion 14. In the openings of the overlap 1, elementwise protrusions pivot sleeve 6, the surface 19 of the sleeve 6 can contact the surface 18 of the annular head 16. The sleeve 6 is inserted into the openings to align its projections with the projection 7

8 m overlap 1 and fixed in this position in a known manner.

When disassembling, the sleeve 6 is unlocked, segmenting protrusions 7 are rotated with overlapping cutouts and removed from the opening of overlap 1, after which the distance ring 15 moves along the conical surface 13 to the cylindrical groove 12. The ring head 16 is lowered along the cylindrical groove 9 until it stops the protrusion 14, opening up access for dismounting the ring lock 11, after which the rotary sleeve 6 and the ring head 16 are removed from the rod 5.

Making the rod of a stand with a spherical notch interacting with the spherical surface of an overslip support and providing the stand with an annular head mounted for movement along the cylindrical bore of the rod and provided with a bore fixing the ring lock improves the performance of the stand, simplifies the design of the rod and its manufacturing technology, provide convenient access to the ring lock, increase the reliability of the device in operation and improve the maintainability of the rack during installation of dismantling operations.
