Abstract
The utility model relates to a tray for mining engineering support, in particular to a strong refined tray. The technical scheme includes that the strong refined tray is provided with a protruding surface, a center hole is formed in the middle of the protruding surface, and a concave and convex surface which is capable of being connected with an anchor rod in a butt joint mode is formed in the inner surface of the center hole. By adopting the technical scheme, the strong refined tray has the advantages of being capable of being not prone to deforming when the strong refined tray bears force below 700KN due to the fact that the strong refined tray is made of ZG45 precision casting materials and the arch-shaped design matches with 14# cast steel, recyclable, simple in structure, capable of greatly enhancing bearing capacity and being used for both the anchor rod and an anchor cable, and recyclable.
Description
Technical field
The utility model relates to the pallet that the mining engineering supporting is used, and is specially a kind of powerful essence casting pallet.
Background technology
The support technology in weak seam tunnel is perplexing the development of mine always.In recent years, aspect the supporting of coal road and alternate heading, the mining area progressively changes the girder steel supporting into anchor pole, anchor cable, the supporting of complexed metal net steel band.According to mode of occupation, weak seam tunnel roof and floor, section of side, supporting intensity or less than normal, often be in instability status, along with appearance and the use of new material, the tensile strength of anchor pole and anchor cable is increasing, the common pallet that uses in the past, more and more can not satisfy the requirement of intensity, distortion often occur, cause the coal rock layer overall offset, cause the roadway deformation amount large, can't satisfy instructions for use.
Summary of the invention
The purpose of invention: in order to strengthen the supporting intensity of tender road, guarantee the space that stope is enough, satisfy the needs of safety in production, avoiding in use being adopted dynamic pressure affects pallet and is out of shape.
In order to reach as above purpose, the present invention takes following technical scheme: it has the surface of projection, described convex surfaces middle part have mesopore, described middle internal surface of hole have can with the male and fomale(M﹠F) of anchor pole docking.
The further technical scheme of the utility model is, the cross section on the surface of described projection is that radian is the arc of r165.
The further technical scheme of the utility model is, described pallet material is ZG45.
The further technical scheme of the utility model is, described median pore diameter is φ 20mm～φ 32mm.
Adopt as above the utility model of technical scheme, have following beneficial effect: adopting the hot investment casting material is ZG45, adopts arc design and 14# cast steel to be used in conjunction with, and is subjected to as indeformable below 700KN recyclable reusing.Simple in structure, bearing capacity strengthens greatly, and anchor pole, anchor cable all can use, and be reusable.
Description of drawings
Accompanying drawing is the structural representation of invention;
Wherein: 1. disk body; 2. mesopore.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described, embodiment is not construed as limiting the invention:
It has the surface of projection, and mesopore 2 is arranged in the middle part of described convex surfaces.
The contact area on the surface of projection is larger, and greatly increased by force intensity.
The shape of two kinds of convex surfaces below is provided, and described shape does not cause restriction to concrete enforcement of the present utility model.
The cross section on the surface of described projection is arc.
By reference to the accompanying drawings; The surface of described projection be by the class sphere of plane cutting.
Described mesopore 2 is positioned at the center on the surface of projection.
Two kinds of docking concepts below are provided, and described docking concept does not cause restriction to concrete enforcement of the present utility model.
Described mesopore 2 has internal thread, also comprises to revolve insertion anchor pole wherein.
Described mesopore 2 inner surfaces have can with the male and fomale(M﹠F) of anchor pole docking.
A kind of preferred size below is provided, and described size does not cause restriction to concrete enforcement of the present utility model.
Adopt bow-shaped structural, increase the bearing capacity that holder is pulled, adopt ZG45, length is 300mm, is highly 60mm, and width is 110mm, and mesopore is φ 20mm～φ 32mm.
Powerful essence casting pallet, the following statement of structure: adopt hot investment casting, material is ZG45, adopts arc design and 14# cast steel to be used in conjunction with.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that describes in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
