Description

The technical field to which the utility model belongs.

The utility model relates to the mining industry, in particular to anchor supports, and can be used to install tubular anchor supports in the mine workings of mines and mines.

The prior art.

Known devices for installing tubular anchors (RU 124736 U1, 02/10/2013. SU 1670144 A1, 08/15/1991. SU 1500785 A, 08/15/1989. SU 1739045 A1, 06/07/1992. RU 167221 A1, 07/28/2016).

The prototype is a well-known device for installing tubular anchors, the closest in technical essence to the proposed utility model (RU 167221 A1, 07.28.2016).

A known device for installing tubular anchors, including a base and coaxially mounted on it, with the possibility of free rotation around the longitudinal axis, a striker with a protrusion in contact with the base on mutually perpendicular surfaces, a cavity made in the striker in the form of part of a toroidal surface and connected to the protrusion, an axial hole for flushing fluid, made in the base, characterized in that the base has a cylindrical part passing through the hammer, and the protrusion is made in the form of a truncated cone, the base of which is directed to the toroidal surface.

The disadvantage of the technical solution adopted for the prototype is that the cylindrical part passing through the firing pin is not applicable for the installation of tubular friction anchors of the W-profile (RU 170365 U1, 06/07/2016) due to possible deformations bent into the edges of the longitudinal slot in the tail of the anchor.

Disclosure of a utility model.

The technical result, which the proposed utility model is aimed at, is the unification of the device for installing tubular anchors of various types.

The technical result is achieved in that the device for installing tubular anchors consists of a metal cylindrical base with a conical narrowing, in which a hole is made for installation on the shank or a segment of the drill rod of a self-propelled drilling rig or hand drill from one end, with a cylindrical shaft with a conical narrowing - with the other end, while its base is a truncated cone of a larger diameter than the diameter of the cylindrical rod, and the place of articulation of the truncated cone with the base in It is satisfied as part torroidalnoy surface to allow installation of the tubular tail section of the anchor into the hole.

The utility model is illustrated by images showing longitudinal sections of a device for installing a tubular anchor.

Implementation of a utility model.

диаметра, чем диаметр цилиндрического стержня 4, а место сочленения усеченного конуса с основанием выполнено в виде части тороидальной поверхности 7, в которую устанавливается хвостовая часть трубчатого анкера 15 при установке в шпур (скважину).A device for installing tubular anchors consists of a metal cylindrical base 1 with a conical narrowing 2, in which a hole 3 is made for installation on the shank or a segment of the drill rod of a self-propelled drilling rig or hand drill from one end, with a cylindrical rod 4 with a conical narrowing 5 from the other end , while its base is a truncated cone 6

diameter than the diameter of the cylindrical rod 4, and the junction of the truncated cone with the base is made in the form of a part of the toroidal surface 7, into which the tail part of the tubular anchor 15 is installed when installed in a hole (well).

The work of the proposed device for installing tubular anchors is as follows. After drilling the holes on the boom of the feeder of the self-propelled drilling rig 12 or on the manual puncher, instead of the drill rod, a rod 13 with a device for installing tubular anchors 14 is installed. Next, the anchor 15 with the tail part 16 is put on the device for installing tubular anchors 14 and installed in the guide (rest) 17 A supporting element 18 is installed on the anchor. The head end of the anchor in the form of a truncated cone 19 is inserted into a hole of a smaller diameter than the diameter of the anchor and by the impact of the perforator on the tail The anchor is sent to the moment of pressing the supporting element of the soil (rock mass). A device for installing tubular anchors performs the function of transferring the impact energy of a perforator to the body of the anchor.

Possible design of a device for installing tubular anchors:

- at the base there is a through hole 3 in the form of a cone for landing on a segment of the drill rod or the shank of a self-propelled drilling rig;

- at the base there is a through hole 3 in the form of a cylinder with a thread for landing on a segment of the drill rod 13 or the shank of a self-propelled drilling rig. The thread can be made in various ways;

- at the base there is a through hole 8 for the entire length of the device for supplying washing liquid;

- the device for installing tubular anchors is made of two parts - the base 1 and the striker 9, interconnected by means of a thread 10 so that the striker 9 and the base 1 can rotate relative to each other, while not twisting. The thread can be made in various ways. At the base, an additional channel 11 is provided for supplying washing liquid to the cavity of the junction with the base.

The technical result claimed when applying for a patent for a utility model is achieved by the combination of its essential features specified in the formula. The significance of all the features of the utility model is confirmed by a causal relationship between the features of the utility model formula and the technical result.

The utility model meets the conditions of patentability “novelty” and “industrial applicability”, which is confirmed during pilot tests in real conditions of mine workings of mines and mines.
