Abstract

The anchor support washer with retainer belongs to the mining industry and can be used as part of anchor support for attaching mines and mines. The anchor support washer with retainer is a rectangular or square metal plate with a hemispherical bulge in the central part with a central hole for the anchor and bent end along one of the sides. A hole with slots is made in the bent end of the support washer for reliable fastening of the latch. The latch is made of rolled round profile and is a metal pin, flattened at one end and bent at a right angle from the other end.

Description

The technical field to which the utility model relates.

The utility model relates to the mining industry, in particular to anchor supports, and can be used as part of anchor support for attaching mining workings of mines and mines.

State of the art

Known support washers for anchor support (RU No. 98049 U1 05/07/2010, RU No. 158,225 U1 06/04/2015, RU No. 89612 U1 07/07/2009, RU 17566 U1 IPC E21D 21/00, US patent No. 4249835 1981, US patent No. 4112693 1978, US patent No. 4552174 1986, Austrian patent No. 355043 1980, UK patent No. 935778 1963).

Known support washer anchor support, closest in technical essence to the proposed model. The anchor support washer contains a metal flat plate of square or rectangular shape with a spherical protrusion and an anchor hole, a rib highlighted in a flat plate on the side of the spherical protrusion, characterized in that the rib planes are directed towards the spherical protrusion, it has a through, longitudinal groove directed to a flat plate, and an expansion wedge installed in a longitudinal groove (RU No. 158225 U1 06/04/2015).

The disadvantage of the prototype is that when installing the anchor lining, it is necessary to position the support washer so that the wedge pressing the mesh against the rock mass is located from top to bottom, otherwise there is a possibility of it falling onto the working soil. This is especially problematic when installing tubular friction supports, as when driven by a manual punch or a self-propelled drilling rig, the support washer will rotate relative to the starting position on the anchor. When “beating” the anchors, i.e. in a situation when the base plate of the anchor lining will not be pressed to the rock mass, the likelihood of a wedge falling on the excavation soil is also high. Wedges that have fallen from the support washer onto the soil with their sharp edges can disrupt the integrity of the wheels of self-propelled vehicles, which can lead to their downtime.

Disclosure of invention

The technical result, the achievement of which the proposed utility model is aimed at, is to increase the reliability of fixing a metal or plastic mesh to enclose a rock mass.

The technical result is achieved by the fact that the support washer of the anchor support with the lock is a rectangular or square metal plate with a hemispherical convexity in the central part with a central hole under the anchor and a bent end along one of the sides. A hole with slots is made in the bent end of the support washer for reliable fastening of the latch. The latch is made of rolled round profile and is a metal pin, flattened at one end, and bent at a right angle from the other end to shift the center of gravity and securely fix in the support washer.

The implementation of the invention

The supporting washer of the anchor support with a latch is a rectangular or square metal plate with a hemispherical bulge 1 in the central part with a central hole 2 under the anchor and a bent end 3 along one of the sides. An opening with slots 4 is made in the bent end of the support washer for reliable fastening of the latch. The latch 5 is made of rolled round profile and is a metal pin, flattened at one end and bent at a right angle from the other end to shift the center of gravity and securely fix in the support washer. The holder 6 is made of reinforcing bars welded together at right angles.

The use of a supporting washer with a lock on the example of a tubular friction lining is made as follows.

After drilling the boreholes, a boom with an adapter (punch) is installed instead of the drill rod on the boom of the feeder of the self-propelled drilling rig or on a manual punch. Next, the tail anchor is put on the punch and installed in the guide (rest). A support washer is installed on the anchor. The head end of the cone-shaped anchor is inserted into the borehole of a smaller diameter than the diameter of the anchor and by the impact of the perforator on the tail part, the anchor is sent to the moment when the rock mass is pressed by the support washer. Next, a guarding mesh 7 is put on the bent end 3 of the support washer 7, pressed by a retainer 6 made of welded reinforcing bars, which in turn is pressed by the clamp 5. The design of the clamp 5 is made in such a way, eliminates its spontaneous fall on the working soil, and therefore the support the washer does not require prior positioning. When using other types of anchoring, only the method of installing the anchor is changed, the method of installing the support washer of the anchor support with the lock does not change.

Claims (1)
