Description
Technical field
The invention belongs to a kind of coal mine machinery, particularly a kind of support removing platform withdrawn applied to force piece.
Background technology
When coal mine work area is removed, the order of equipment returning is generally bunching, elevating conveyor, transporter, coalcutter, stent.
Stent is the emphasis in the equipment finally withdrawn in working face demolishing process, and working face demolishing process.Withdrew stent in the past
When need using shield support, three kinds of equipment mate-assists of support removing platform and winch.Wherein shield support uses 4000/
17/35 type stent is usually placed in rolling back and rationalizing on triangulation point for working face, with branch in the rack restoring course of work, it is necessary to 3 groups
Withdrawing for frame and move, the pan frontward end of shield support and need to be withdrawn the outer end alignment of stent, during the work time mainly
Support action is played, prevents top plate chip off-falling from hurting sb.'s feelings.Existing support removing platform using the steering for for many years, being mainly responsible for stent and on
Flatcar works, and is connected by connector with shield support.Winch is mainly responsible for the traction work during rack restoring, is arranged in
Fortune is along on triangulation point.
Stent to withdraw process as follows：By the push-and-pull head for being withdrawn stent and removed solid on platform first by 26 round-link chains
Fixed card chain device is connected, and shifting, the card chain device by selecting diverse location certainly that the flexible completion stent of cylinder is pushed and pulled by stent are complete
Into by the steering of removing supporters, by winch towing bracket, the height of 400mm is improved along the inclined-plane for removing platform, by flatcar and
Remove platform to fix, continue towing bracket, stent is pulled on flatcar, stent peace lock jail will be equipped with using winch
The flatcar of stent is drawn between the lifting for decomposing stent, then withdraws railway, operates the push-and-pull cylinder of shield support, and adjustment is removed flat
The position of platform and shield support, after adjusting, carry out next pack support withdraws work.
Colliery withdraws stent using which always for many years, with continuously improving for operation technique, underground coal mine machinery
The popularization of change, work efficiency are continuously improved, and trouble free service requirement constantly lifting, it is found that above-mentioned dismounting platform is deposited in use
In problems with：
1st, stent, which is moved to, removes on platform, and the steering work of first half is by withdrawing branch on platform is removed
Frame push-and-pull is from moving what is completed, and the work redirecting between flatcar of latter half is led by drawing hoist on platform is removed
Draw completion, in distraction procedure, in order to ensure that stent can upper flatcar, the latter half for removing platform be smoothly to go up a slope, this
Sample adds the tractive force of drawing hoist, reduces the service life of drawing hoist and steel wire rope.
2nd, stent is moved to the mode used on flatcar first to fix flatcar from platform is removed, and is then led using drawing hoist
Draw stent, stent is drawn on flatcar, in distraction procedure, swipe phenomenon occur, be easy to cause wire cable rupture；Stent exists
When being laid particular stress on flatcar, it be easy to cause flatcar and slides down；It is hazardous area by towing bracket to the region between drawing hoist during traction
Domain, all operations must stop, and influence job scheduling.
3rd, work efficiency is low.When withdrawing stent, after can only a pack support be withdrawn from, by two groups of shield supports and platform is removed
After being moved to designated position, the work that withdraws of next pack support can be carried out, work efficiency is low.
Therefore a kind of new support removing platform is urgently provided at present, to meet that the rack restoring of production work works.
The content of the invention
The object of the present invention is to provide the device that a kind of underground coal mine working face withdraws stent, the work of rack restoring can be improved
Make efficiency, be especially greatly improved in the secure context for withdrawing stent work.
The purpose of the present invention is what is be achieved through the following technical solutions：It includes connector, pushes and pulls thick stick, raised platform, turns
To platform I, platform II, card chain device I, diversion baffle, contiguous block I, contiguous block II, entrucking seat, card chain device II, a davit are turned to,
It is characterized in that：The one end for turning to platform I is hinged raised platform by connecting lug and axis pin；Turn to the connection of platform I and turn to platform
II, it is respectively provided with card chain device I in the one end for turning to I one end of platform and steering platform II；Fix and turn in the other end for turning to platform II
To plate washer；
Entrucking seat is set in the other end of the present apparatus, lifting column is set respectively on four angles of entrucking seat, in entrucking seat
Tail end assembling card chain device II；
Telescopic component is connected between platform II and entrucking seat turning to, sets push-and-pull cylinder to stretch group in the both sides of telescopic component
Part sets outer sliding sleeve, and inserting inner slide, the connection lug and pin and entrucking seat that outer sliding sleeve passes through one end are slided in outer sliding sleeve
Connection, inner slide are connected by the connection lug and pin of one end with turning to platform II；Push-and-pull cylinder one end lug of both sides passes through
Contiguous block is connected with pin turns to platform II, and other end lug by contiguous block by connecting entrucking seat with pin.
Above-mentioned lifting column sets the lifting column overcoat being fixedly connected on entrucking seat, and being assembled in lifting column overcoat can be up and down
The sliding inner sleeve of slip, sliding inner sleeve upper end connection upper binding head, sets lifting hydraulic cylinder, lifting hydraulic cylinder in sliding inner sleeve
Lower connection lug with lift column housing base attaching clamp be connected by axis pin, the upper connection lug of lifting hydraulic cylinder with it is upper
Connector is connected by axis pin.
Longitudinal boss is set on the inner wall of above-mentioned outer sliding sleeve, opens up longitudinal notch on inner slide, on outer sliding sleeve inner wall
Longitudinal boss slides in the longitudinal notch on inner slide.
The positive effect of the present invention is as follows：
1st, it is safe.Compare, drawn by flatcar on removing supporters using lifting hydraulic cylinder, hydraulic cylinder with conventional platform of removing
Parameter be shown in Table one, the thrust of single lift cylinders is 48.5T, and making a concerted effort for four lift cylinders is 194T, and crane capacity can fully expire
Foot requires.
Table one：Lift cylinders technical parameter
2nd, work efficiency is high.The support removing platform used in the past, can only once withdraw a pack support, and the present apparatus can return
The second pack support is carried out while removing the first pack support withdraws work, and the work for withdrawing railway is also withdrawn from pervious 1.5 meters
Once, it is changed to 3 meters to withdraw once, work efficiency is greatly improved.
3rd, service life of steel wire rope is improved.The structure of platform, in rope traction stent to go up a slope, traction were removed in the past
Power is big, and rope service-life is shorter, and using the present apparatus, steel wire rope only draws the stent for installing flatcar, and tractive force is smaller than in the past
Very much, therefore the service life of steel wire rope is greatly improved.
