Abstract

A novel anchor bolt consists of a steel pipe and a triangle steel wire. The triangle steel wire is fixed on the steel pipe by high-strength adhesives. When the anchor bolt is screwed in a coal bed, the coal bed is pressed to deform and the triangle steel wire produces anchorage force to form full-length of anchorage. The invention of the utility model helps improve the coefficient of recovery of the anchor bolt by 20 per cent and reduce the production and use cost of bolting by one-third, with good recovery and cutting performance; the utility model extends time for coal mining, speeds construction progress of coal mining enterprises and increases benefit for service units as an economic and practical novel anchor bolt.

Description

Novel anchor " bar

The utility model relates to the coal road Anchor Care, specifically a kind of bonding profile wire anchor pole.

Existing bolt support is compared with traditional shed ding support, has significant Technological Economy superiority.But used anchor pole is generally disposable use in the bolt support, has improved use cost relatively.Recoverable anchor rod also can only reclaim the body of rod, and the inside and outside plastic casing on the body of rod is stayed in the coal seam, has increased use cost.Though there is a kind of welding to reclaim anchor pole, because steel wire welded is connected on the body of rod, a large amount of solder joints are arranged, not only increased cost of production, and the working resistance that produces because of solder joint reduces the rate of recovery.

The purpose of this utility model just provides a kind of rate of recovery that improves anchor pole, increase substantially labor productivity, reduce bolt support the production use cost, can be the novel anchor rod that coal system brings better economic benefit.

The utility model is to realize like this, the novel anchor rod of forming by steel pipe, triangle steel wire, by the high strength bonding agent the triangle fixation with steel wire to steel pipe, screw-thread steel one end and steel pipe welding, the other end is connected with the pallet that has drive nut, and in the time of in anchor pole screws in the coal seam, the coal seam produces pressure distortion, the triangle steel wire has just produced anchored force in the coal seam, form full length fastening.

Be described in detail the utility model below in conjunction with drawings and Examples.

Accompanying drawing is the utility model general structure schematic diagram.

As shown in drawings, anchor pole is by steel pipe 1, triangle steel wire 3 is formed, on the steel pipe 1 during coiling triangle steel wire 3, extrude high-strength structureal adhesives (its adhesive is the modification acrylate of selling on the market) by two gear oil pumps, with the spout of adhesive by the gear oil pump tubule, be sprayed onto the bottom surface of triangle steel wire 3, and be blended on the bonding surface of steel wire 3 and steel pipe 1, steel wire 3 by high-strength structureal adhesives 2 with steel pipe 1 strong bonded together, again with screw-thread steel 4 welding, the other end of screw-thread steel 4 is connected with the pallet 5 that has drive nut 6, and pallet 5 is installed on road, the coal seam rib, plays support action.During use, get out the boring that is about 2 meters with pneumatic drilling machine earlier, anchor pole is revolved in the coal inlet with pneumatic drilling machine again, tray 5, drive nut 6 can be realized full length fastening again.After seam mining is intact, with pneumatic drilling machine anchor pole is screwed out recovery, reuse with realization, this anchor pole uses three times at least.

Adopt the beneficial effects of the utility model:

1. save producing cost, if steel wire is welded on the body of rod, artificial 0.45 yuan of welding cost, the electricity charge 0.3 unit, 0.25 yuan of welding rod amounts to 0.96 yuan. And adopt the utility model to only have 0.1 yuan of fee of material, Every production cost reduces by 0.86 yuan.

2. improve anchor pole productivity ratio, because there not being this procedure of welding wire, productivity ratio is doubled More than, under same working condition, make the profit of manufacturing enterprise improve nearly twice.

3. improved the rate of recovery,, can make the rate of recovery improve about 20%, so applying unit has reduced production costs significantly owing to do not have solder joint on the body of rod.

4. because anchor pole rate of recovery height, but and recycled in its entirety, but therefore cutting is good, reduces tool damage in the time of can avoiding the coal-winning machine coal cutting significantly.

5. accelerated the construction speed of producing coal enterprise, because without the anchoring agent, when skyhook, there is not the mixing process of setting of anchoring agent in the utility model, anchor pole can directly be screwed in the coal seam by pneumatic drilling machine, just can play anchorage effect.Therefore, can increase substantially construction speed, improve the production efficiency of producing coal enterprise.
