Description

Aligning shearing-resistant anchorage device

Technical Field

The utility model belongs to the technical field of the anchor rope supporting technology and specifically relates to an aligning ground tackle that shears.

Background

The anchor cable has the characteristics of strong support with high strength and high pretightening force, and is widely applied to working conditions such as coal mines, deep foundation pits and the like. The anchor cable is tensioned and pre-tightened by an anchorage device, so that the active supporting function is exerted. The anchor structure that adopts at present is cylindrical, and the hole is toper and clamping piece cooperation, installs the anchor on the anchor rope through stretch-draw machines. When the mounting hole and the surface of the roadway form an included angle of 90 degrees, the defects of the anchorage device are not obviously reflected. The disadvantages of the anchorage device appear when the included angle between the mounting hole and the roadway surface is less than 90 degrees. The anchor cable support device has the concrete characteristics that the anchor cable is enabled to bear bending moment due to the fact that the anchor cable does not have the aligning function, and therefore damage is caused to the anchor cable body, and support performance is affected. Moreover, because do not possess anti-shear function, anchor disc displacement and then produce the shearing force to the anchor rope when the tunnel warp. Therefore, it is necessary to design a self-aligning shear anchor.

SUMMERY OF THE UTILITY MODEL

For solving the problem that the common mould does not have the shearing resistance, the utility model provides an aligning shearing-resistant anchorage device.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an aligning ground tackle that shears, includes anchor disc, anchor ring and flange, anchor disc bottom be equipped with the through-hole, through-hole below be the hemisphere groove, the anchor ring set up inside the flange, flange upper portion be the toper section, the flange lower part be the calabash section, hemisphere inslot be equipped with the spring that shears, the flange lower part set up in the hemisphere inslot.

As optimization, the spring that shears be equipped with a plurality of, spring one end evenly set up on the hemisphere inslot wall, toper section and calabash section link firmly, calabash section upper portion set up on the spring, calabash section lower part set up in the anchor plate outside.

Preferably, the outer coin wall of the anchor ring is attached to the inner wall of the flange, and an anchor cable is arranged in the anchor ring.

Preferably, the upper part of the through hole is a cylindrical groove, and the cylindrical groove is communicated with the hemispherical groove.

The whole beneficial effect of this scheme is: the utility model provides a self-aligning shearing ground tackle is equipped with the hemisphere groove with the bottom through-hole lower part of anchor disc, set up flange upper portion into the toper, the lower part sets up to the calabash type, and set up the spring in the hemisphere inslot, can have the bearing effect to the flange, make the askew of flange can the small range move, make the anchor disc have the ability of shearing, thereby avoid receiving great moment of flexure and being in complicated stress state because the anchor rope afterbody, can be simultaneously with even the applying on the anchor disc of anchor rope pretightning force, full play anchor disc bearing capacity, play the guard action to anchor rope or stock when the anchor disc takes place non-axial displacement, prevent that the body of rod from being destroyed.
