Abstract
The invention relates to an umbrella type hole packer. The umbrella type hole packer is characterized in that a fixed sleeve and a sliding sleeve are fixedly sleeved in the middle of a drainage pipe, upper braces and lower braces are respectively uniformly distributed and hinged on the outer side of the fixed sleeve and the outer side of the sliding sleeve, the other ends of the upper braces are hinged with the other ends of the lower braces, and shield cloth is arranged at the other ends of the upper braces and the other ends of the lower braces; and branch ropes are fixed onto the sliding sleeve and are connected with a main rope after respectively entering the drainage pipe via guide holes, and the main rope is led out of the outer end of the drainage pipe. The umbrella type hole packer has the advantages that a support layer can be quickly arranged in a drilled hole and can be formed without curing time, so that cement can be quickly sprayed to form a fixing layer advantageously, and the work efficiency is improved; the umbrella type hole packer which is of a mechanical structure can be machined and assembled on a large scale, existing necessary mixing materials are saved, and accordingly the cost is saved; and the main rope can be broken after being used, so that materials are saved, and the umbrella type hole packer is reasonable in structural design and quite favorable for popularization and implementation, and can be used conveniently and effectively.
Description
Technical field
The present invention relates to the gas drainage under suction instrument that uses in the field, a kind of colliery, particularly the special-purpose umbrella formula in a kind of colliery hole packer.
Background technology
Because gas threatens the safety of coal mining, gas under the coal mine in the wall pump drainage coal seam, tunnel becomes one important step before the coal mining, the coal seam is in the underground high-voltage state, gas is closed in inside, coal seam usually and is not easy to discharge, but outstanding accident can take place, so also be accompanied by the gas exhaust operation in recovery process when changing the coal seam stress balance in recovery process.The mode of traditional pump drainage gas is to hole at rib, and releasing pipe of insertion is distributed with aspirating hole on the inner end of releasing pipe in boring.Releasing pipe need be sealed fixing in boring, the mode of taking is: at releasing pipe middle part or be provided with the material of two kinds of different materials near boring collar extension one side, when releasing pipe is placed into the appropriate location two kinds of materials being mixed generation expands, thereby make between releasing pipe and the boring inwall and form one deck supporting layer, after layer to be supported solidified, at supporting layer outside sprinkling irrigation cement, the back that thes cement solidifies formed sealant, then exhaust column is bled, the gas of rib inboard is released.There is the problem of inefficiency and support strength deficiency in above traditional approach, two kinds of materials are by mixed expanded formation supporting layer, need certain setting time, and this expansion does not in axial direction suffer restraints, shutoff imprecision problem can appear, thereby easy spillage when gunning concrete is wasted concrete and is caused aspirating hole shutoff problem easily, does not reach the effect of bleeding.And traditional mode needs to consume a large amount of mixed materials and could form supporting layer, has increased cost of winning.
