Referring to fig. 1-3, the present invention provides a technical solution: a supporting device for an iron ore mining and cutting process comprises an arc-shaped support 1 and supporting structures arranged on the left side and the right side of the arc-shaped support 1; the arc-shaped support 1 comprises an arc-shaped framework 2, a metal mesh grid 3 is arranged at the top end of the arc-shaped framework 2, a compression resistant layer 4 is arranged at the bottom of the arc-shaped framework 2, the compression resistant layer 4 comprises an upper supporting layer 5 and a lower supporting layer 6, and a compression resistant rod 7 with a hemispherical structure is connected between the upper supporting layer 5 and the lower supporting layer 6;

the supporting structure comprises a supporting anchor rod 8 connected with the lower surface of the arc-shaped support 1, a mounting groove 9 for the arc-shaped support 1 is formed in the top end of the supporting anchor rod 8, the bottom of the arc-shaped support 1 is sleeved inside the mounting groove 9, and telescopic buffer structures 10 are connected between the left side and the right side of the arc-shaped support 1 and the inner wall of the mounting groove 9; the bottom of supporting stock 8 is provided with pointed end 11, and the bottom of pointed end 11 is provided with fixed mounting 12, is provided with the constant head tank that is used for the installation to support stock 8 on the fixed mounting 12, and the bottom of constant head tank be provided with the tapered slot of 11 adaptations of pointed end.

Further, flexible buffer structure 10 includes connecting rod 14 of being connected with arc support 1 bottom, and the pot head that connecting rod 14 kept away from arc support 1 is equipped with flexible post 15, and the inside of flexible post 15 is provided with the cylindricality spout with the 14 radian adaptations of connecting rod, and the one end that connecting rod 14 is close to flexible post 15 is provided with limiting plate 17, and the cover is equipped with reset spring 16 on connecting rod 14.

Further, the fixed mounting seat 12 and the support anchor 8 are provided with mounting holes for connecting bolts 13.

Furthermore, a first permanent magnet block 20 is arranged inside the tip portion 11, a second permanent magnet block 18 is arranged inside the tapered slot, and the first permanent magnet block 20 and the second permanent magnet block 18 are magnetically attracted.

Further, a counterweight 19 is disposed at the bottom of the fixed mounting seat 12.

The working principle is as follows: when the supporting device is used, when the arc-shaped support 1 is subjected to pressure or impact force from the top end, the arc-shaped framework 2 plays a role in supporting and protecting the whole arc-shaped support 1, and the metal mesh grid 3 above the arc-shaped framework 2 plays a certain role in protecting the arc-shaped framework 2 through the self compressive strength and tensile strength of the metal mesh grid, so that the arc-shaped framework 2 is prevented from deforming; when the compression-resistant layer 4 at the bottom of the arc-shaped framework 2 receives the impact force from the arc-shaped framework 2, the compression-resistant rod 7 inside the compression-resistant layer plays a role in high-strength pressure bearing and buffering for the whole arc-shaped framework 2, particularly for the bottom of the arc-shaped framework 2, and the arc-shaped framework 2 is further broken or deformed.

When arc support 1 wholly receives to come from the great impact force in top, the outside expansion of the left and right sides of arc support 1 for connecting rod 14 and arc support 1 on the lateral wall of arc support 1 bottom are the syntropy displacement motion, and connecting rod 14 removes along the cylindricality spout direction in flexible post 15, under reset spring 16's effect, makes flexible buffer structure 10 reach the purpose that cushions and elasticity reset arc support 1, improves arc support 1's whole compressive strength.

Because the supporting anchor rod 8 is inserted into the fixed mounting seat 12 from the bottom and the tip end 11 of the bottom when being mounted, the bolt 13 sequentially penetrates through the mounting holes on the supporting anchor rod 8 and the fixed mounting seat 12 and is fixedly assembled by the nut, and the first permanent magnet block 20 inside the tip end 11 and the second permanent magnet block 18 inside the conical groove are magnetically attracted, the supporting anchor rod 8 is prevented from falling to a certain extent, and the stability of the supporting anchor rod 8 is effectively improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
