Description
Technical field
Stepping movable type Track device, belongs to and connects beam car technical field.
Background technology
Advanced 20 meters of supporting states in China's coal-mine down-hole combined mining working air way road, major part is that hydraulic prop supports π section steel beam, workman's hands pickaback lift, and physical labor intensity is bigger, poor stability, has a long way to go with the modern state mined of comprehensive mechanization automatization.
Summary of the invention
The technical problem to be solved is to provide a kind of Simple transportation device and can be automatically moved by the advance timbering of advanced 20 meters of supportings in air way road.
For solving above-mentioned technical problem, the technical solution adopted in the present invention: stepping movable type Track device, including stepping moving device, passage oil cylinder, winch, track, connect beam dolly and movable pulley, described stepping moving device, passage oil cylinder and winch are arranged at one end of track, described movable pulley is arranged on the other end of track, is provided with and can connect beam dolly along what track was walked on described track；
Described stepping moving device includes two pack supports that interval is arranged, structure is identical, the structure of described support is: two columns and the crossbeam of two columns of connection, and two equal tops of column are provided with support oil cylinder, setting ground, a bottom oil cylinder, described two pack support middle beams are connected by passage oil cylinder, and fix another pack support being connected with passage cylinder piston rod with the pack support that is connected at the bottom of passage oil cylinder with track and pass through roller and be connected with track rolling.
The piston rod head of described cradle top support oil cylinder is provided with the bulb being easy to support, and described column bottom is propped up the piston rod head of ground oil cylinder and is provided with the bulb being easy to support.
Compared to the prior art the present invention has the advantages that.
One, the present invention realizes the fixing support to track by stepping moving device, movable pulley, pull the beam dolly that connects being arranged on track to walk along track further through winch, connect above the Jie Liang mechanism of beam dolly owing to advance timbering is arranged on, therefore winch pulls and connects beam dolly, makes advance timbering, connects beam carriage walking to specifying position；
nullWhen track moves，Need the support oil cylinder first by two columns with passage cylinder piston rod connection、Prop up ground oil cylinder to retract respectively，Then the piston rod of elongation passage oil cylinder，Due to the support oil cylinder with two columns connected at the bottom of passage oil cylinder、Prop up ground oil cylinder and be sky, top、Stationary state on the spot，So two columns connected with passage cylinder piston rod are just passed oil cylinder and promote forward the segment distance stroke of oil cylinder (segment distance i.e. elapse)，It is passed two columns after oil cylinder pushing one segment distance again by support oil cylinder、Prop up ground oil cylinder to revert to push up sky、Stationary state on the spot，The most again by the support oil cylinder with two columns connected at the bottom of passage oil cylinder、Prop up ground oil cylinder to retract respectively，Then the piston rod shrinking passage oil cylinder will also be pulled along a segment distance with two columns connected at the bottom of passage oil cylinder，Meanwhile，Track moves forward a segment distance the most therewith，The most again by the support oil cylinder with two columns connected at the bottom of passage oil cylinder after having pulled、Prop up ground oil cylinder and recover sky, top、Stationary state on the spot，At this moment，Can be pulled by winch again and connect beam dolly and start new circulation transport along track walking；
In sum, the present invention is not only simple in structure, with low cost, and also has the advantage that track mobility is strong, conevying efficiency is high, safety is good.
Two, the present invention is by being respectively provided with bulb at the piston rod of the support oil cylinder of column, a ground oil cylinder so that support oil cylinder, a ground oil cylinder are when pushing up sky, on the spot state, even if also being able to when back, pucking are the most smooth realize stable support.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
In figure, 1 is stepping moving device, and 2 is passage oil cylinder, and 3 is winch, and 4 is track, and 5 for connecing beam dolly, and 6 is movable pulley.
Detailed description of the invention
As shown in Figure 1 and Figure 2, stepping movable type Track device, including stepping moving device 1, passage oil cylinder 2, winch 3, track 4, connect beam dolly 5 and movable pulley 6, described stepping moving device 1, passage oil cylinder 2 and winch 3 are arranged at one end of track 4, described movable pulley 6 is arranged on the other end of track 4, is provided with and can connect beam dolly 5 along what track 4 was walked on described track 4；
Described stepping moving device 1 includes two pack supports that interval is arranged, structure is identical, the structure of described support is: two columns and the crossbeam of two columns of connection, and two equal tops of column are provided with support oil cylinder, setting ground, a bottom oil cylinder, described two pack support middle beams connect by elapsing oil cylinder 2, and a pack support another pack support that with passage oil cylinder 2 piston rod be connected fixing with track 4 being connected with passage oil cylinder 2 cylinder bottom is connected with track 4 rolling by roller.
The piston rod head of described cradle top support oil cylinder is provided with the bulb being easy to support, and described column bottom is propped up the piston rod head of ground oil cylinder and is provided with the bulb being easy to support.
Described winch 3, passage oil cylinder 2, connect beam dolly 5 and be prior art.
The work process of the present invention is: one, advanced hydraulic support is first arranged on 20 meters of positions inside air way, by connecing the centre position that beam dolly 5 reaches need immediately below the advance timbering of movement, connects high-pressure emulsification liquid pipeline afterwards.
Two, rise and meet the Jie Liang mechanism of beam dolly 5 and catch the beam of advance timbering and beam is clamped.
Three, by advance timbering pressure release, setting position is dropped to.
Four, by connecing the rotary oil cylinder of beam dolly 5 by advance timbering rotation 50 degree so that advance timbering two heel post is separately fixed at and connects beam dolly 5 both sides.
