Description
Technical field
The present invention relates to coal excavation apparatus to use technical field, particularly belongs to a kind of soft bottom fully-mechanized mining working of float coal and tears frame work open
Skill.
Background technology
With the application of the high-power coal excavation apparatus of mine, fully-mechanized mining working stoping work is gradually improved, and causes underground fully mechanized mining
The equipment installation of working face is taken over frequently with recovery.
Number of patent application discloses a kind of recovery method of common combined mining working face hydraulic support for 201010285209.9
Technical scheme, in the technical scheme, improvement in thinking is carried out for the frame method of removing of two traditional frame supportings, has been further added by
One hydraulic support thus has three hydraulic supports to carry out alternately shielding, in the technical scheme as shield support, it is indicated that
What is used is one, two, No. three support reciprocal as cover frame, and how the position adjustment of three supports is and tunnel by Special attention will be given to
Side by side.
Number of patent application discloses a kind of modified fully-mechanized mining working surface hydraulic support withdrawing technique for 201210331892.4.
Solve the technical problem that fully-mechanized mining working whole hydraulic support quickly reclaims, entered first with the winch that withdraws of working face in working face
Row support withdraws work, using removing after force piece withdraws out original position by frame winch, then utilizes the winch at 50 framves
Progress entrucking is shelved at platform with dragging it to, is transported support with track with shelving flatcar again using the winch of shelving of working face
Defeated mode is transported, and so circulation three times can withdraw from support.The program mainly be to number of patent application
201010285209.9 a kind of technical scheme of recovery method of common combined mining working face hydraulic support is disclosed further to improve, it is main
Improve utilization rate of equipment and installations.But after fully-mechanized mining working pushes to adopt, if recovery lane bottom plate float coal is more or bottom plate dirt band is relatively thin softer
It is soft, during rack restoring, necessarily dirt band is destroyed when being consigned directly up along recovery eye, causes support to penetrate in recovery intraocular float coal
It can not withdraw, while the support for being pulled to recovery eye upper end reluctantly necessarily carries a large amount of float coal, after support pulls out, it is necessary to which cleaning is big
Float coal is measured, causes support recovery operation at this to become extremely difficult, and is stretched the meaning, easily winch cable is broken and caused
Casualty accident, so the purpose that whole working surface hydraulic support quickly reclaims can not be realized
The content of the invention
It is an object of the invention to provide a kind of soft bottom fully-mechanized mining working of float coal to tear frame technique open, overcomes prior art not
Foot, it effectively prevent direct drag bracket and cause recovery eye float coal to accumulate the problem for hindering frame, after support is fallen out, by small
Loading platform easily first-class slide plate, is then directly pulled to upper end along track, and technique is simple, and safety coefficient is high, operates
It is time saving and energy saving to come, and in support and upper crossheading entrucking position does not have float coal substantially, eliminates the cumbersome process of the clear float coal of per tour, significantly
Reduce the labor intensity of worker, hence it is evident that improve work task efficiency.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of soft bottom fully-mechanized mining working of float coal tears frame technique open, comprises the following steps：(1) preparation before recovery support：
Working face recovery lays track in lane, and in track lower ends, one piece of chain-wales for installing slide plate, chain-wales are overlapped with screw
Rectangular triangular pyramidal, while make that one slide-plate is standby, postive stop baffle is welded with below described slide plate, described slide plate is spacing
Baffle plate coordinates with railway, is stuck in railway and freely slides up and down；
(2) rack restoring：After support is fallen out, support is pulled on by chain-wales by winch, after tilting support seat-box front end,
Slide plate is connected by timberer with seat-box before support by two screws, the first-class slide plate of support, it is ensured that after stable, starting winch will
Support is drawn forward, and after slide plate postive stop baffle blocks railway, support is pulled into working face upper end along track by the slide plate,
Then personnel lay down screw and slide plate, by support tuning and are pulled at loading platform；
(3) support reclaims：Described loading platform both sides are welded with platen support, push down platen support by monomer column to fix dress
Car platform, described loading platform one end are welded with short railway, and described short railway is connected by road clamping plate with railway, and described is short
Be provided with flat car and attachment means above railway, described flat car put off till along short railway with loading platform together with after, connection dress
Put and docked with flat car link slot, be plugged pin, flat car is connected together with loading platform, described loading platform upper table
Face and flat car upper surface flush, support pull on loading platform by winch, then pull on flat car by loading platform.
Further, the track is withdrawn with rack restoring.
Further, described chain-wales both sides platen support position is equipped with a hydraulic prop.
Compared with prior art, implementation result of the invention is as follows by the present invention：
The soft bottom fully-mechanized mining working of a kind of float coal of the present invention tears frame technique open, effectively prevent direct drag bracket and causes
Recovery eye float coal accumulation hinders the problem of frame, after support is fallen out, passes through small loading platform easily first-class slide plate, Ran Houzhi
Connect along track and be pulled to upper end, technique is simple, and safety coefficient is high, and it is time saving and energy saving to operate, in support and upper crossheading entrucking position
Put does not have float coal substantially, eliminates the cumbersome process of the clear float coal of per tour, greatly reduces the labor intensity of worker, hence it is evident that improve
Work task efficiency.
