Description

Hydraulic supporting device for fully-mechanized coal driving workface
Technical field
Suspension device when the present invention relates to the colliery underworkings and carrying out excavation operation is specially a kind of hydraulic supporting device for fully-mechanized coal driving workface.
Background technology
In recent years, along with the heavy-duty of mining equipment under the coal mine and the equipment upgrading of coal-face, many mines have been realized the exploitation of " well one side " coal, and production efficiency has obtained promoting significantly; But because it is not in place to combine not matching of pick equipment, it is lower to cause combining pick efficient, and nearly all mine all in various degree the digging that faces is connected nervous contradiction, and most of mines have to take the measure of " bull protects face " at present.
Under coal mine in the recovery process, the excavation operation in tunnel is the prerequisite of every other operation, along with day by day popularizing of fully-mechanized digging machine, the tunnel of fully mechanized workface flat more traditional " big gun pick " operating type of single water inlet is greatly improved, but, because the tunnel is subjected to the balkstone conditionality, combine tunneling process generally in the following way at present: shut down after the fully-mechanized digging machine driving 0.8-1.2 rice, begin the supporting operation then, carry out artificial supporting with anchor pole, anchor cable or capplce etc.; This desultory cyclic mode of operation speed is slow, labour intensity is big and operating efficiency is low, can not bring into play fully-mechanized digging machine usefulness to greatest extent, therefore driving and the supporting parallel operations that solve fully mechanized workface under the coal mine, achieving synchronously almost is the great technical barrier that all collieries all face continuously.
In recent years, the home and abroad colliery industry has been done a large amount of research and trial in this respect, but still does not have a kind of suspension device that is used to realize fully mechanized workface driving and supporting parallel operations effectively.
Summary of the invention
The present invention does not have a kind of problem that is used to realize the suspension device that fully mechanized workface driving and supporting operation are carried out synchronously continuously at present in order to solve, and a kind of hydraulic supporting device for fully-mechanized coal driving workface is provided.
The present invention adopts following technical scheme to realize: hydraulic supporting device for fully-mechanized coal driving workface, comprise the some supporting top beams that distribute along tunnel fore-and-aft direction (the fully-mechanized digging machine tunneling direction is the place ahead), the inner left and right sides of each supporting top beam all is with the oil cylinder of left and right directions placement and an adjacent end of left and right sides oil cylinder is all fixed with supporting top beam, the other end of oil cylinder all is fixed with extensible canopy, the side that extensible canopy is positioned at the supporting top beam outside all vertically is fixed with the hydraulic prop that is positioned at the supporting top beam left and right sides, the left and right sides of supporting top beam upper surface all has groove, all be connected with slide mass by iron chains in each groove and on the supporting top beam lower surface corresponding with each groove location, the last leg that is equipped with i iron and i iron on the slide mass of the left and right sides, supporting top beam lower surface slides on the slide mass.When excavation operation is carried out in the tunnel, fully-mechanized digging machine is after digging out certain space on the work plane, hydraulic supporting device for fully-mechanized coal driving workface is moved in this space, the oil cylinder that drives in each supporting top beam by hydraulic mechanism extends then, extensible canopy is extrapolated, hydraulic prop is helped near tunnel two, each supporting top beam is raised to back connect the top, temporary lining is realized in this space thereby then drive hydraulic prop elongation; When fully-mechanized digging machine is constantly pushed ahead, pass i iron at first forward, slide mass on the supporting top beam lower surface, rear end slides from i iron, drive the hydraulic prop contraction by hydraulic mechanism then and make supporting top beam landing certain altitude, then the slide mass in this supporting top beam groove is taken out and hang on the following leg of i iron, at this moment oil cylinder and the hydraulic prop that drives on this supporting top beam by hydraulic mechanism shortens, thereby extensible canopy withdrawal, the supporting top beam that then promotes the rear end is to front end, to move to the hydraulic prop and the oil cylinder elongation of the supporting top beam of front end then by hydraulic mechanism, thereby extensible canopy stretches out, supporting is in the tunnel, the supporting top beam of rear end constantly moves to front end and carries out supporting in the process of constantly pushing ahead along with fully-mechanized digging machine, this process constantly circulates, and has realized the purpose that fully mechanized workface excavation operation and supporting operation are carried out synchronously continuously.
Slide mass comprises the pulley base of channel-section steel shape, be installed with the pulley of two axis on same straight line on two legs of pulley base, inboard leg is positioned at pulley on the i iron upper end and two pulleys are positioned at i iron waist both sides, and are when the supporting top beam that promotes the rear end, tunnel during to front slide, convenient laborsaving.
The groove of the supporting top beam left and right sides is two grooves that distribute along fore-and-aft direction, the hydraulic prop that extensible canopy is positioned at a side in the supporting top beam outside is two hydraulic props that distribute along fore-and-aft direction, makes that the structure design of hydraulic supporting device for fully-mechanized coal driving workface is reasonable more, stable.
The outer end of left and right sides extensible canopy is hinged with the face guard near hydraulic prop cylinder body upper outside, when fully-mechanized digging machine carries out excavation operation, can avoid coal petrography stone on the lateral wall of tunnel to drop by face guard and the workman in the tunnel be caused the problem of personal injury.
Have some perforatings hole on the face guard, and have some perforatings hole between the upper and lower end face of supporting top beam and extensible canopy, can realize permanent support to the tunnel, if when taking the hand-holing mode to finish the follow-up permanent support operation in tunnel, can utilize these holes to beat armature boring, and the operation simultaneously of convenient many bench drills is to improve supporting efficient; In addition, the fully-mechanized digging machine rear portion also can supporting fortune anchor all-in-one, follows closely in the position of rear end supporting top beam and carries out the supporting operation; Fortune anchor all-in-one can bore perforating simultaneously, supporting efficient height more; During the hand-holing supporting, operating personnel carry out armature boring fully under hydraulic supporting device for fully-mechanized coal driving workface shielding, for the workman provides safe and reliable bad border of operation.
Be inlaid with the plurality of magnetic iron block on the supporting top beam upper surface, be convenient to roadway support the time, carry out in advance linked network and place the chain beam of anchor pole by the suction-operated of magnet piece.
The present invention has filled up the blank that does not have a kind of suspension device that is used to realize that fully mechanized workface excavation operation and supporting operation are carried out synchronously continuously at present by rational design, original stress and the rock stratum that can not only keep the tunnel at short notice do not change behind excavation, for follow-up permanent support provides condition, and can provide reliable security context for fully mechanized workface operating personnel and equipment, increase substantially supporting efficient when reducing labor intensity, have the advantage that processing is simple, cost is low.
