Contracting.
Steel truss train, as a part for automatic telescopic belt conveyer, is analyzed the dynamic of automatic telescopic belt conveyer and is just understood steel
Truss train dynamic.
Automatic telescopic belt conveyer can be generally used in second link in downhole crossheading transfer system, its head（Uninstalling portion）With
Subordinate's belt machine tail part overlap joint, afterbody and broken elevating conveyor or scraper blade elevating conveyor overlap joint, the unmanned steering mechanism steel at two ends end to end
Cord free end is connected with the central point of neighbouring device.There are two kinds of operating modes：One kind is driving operating mode, and automatic telescopic belt conveyer is stretched
Long, another kind is back to step on operating mode, and automatic telescopic belt conveyer shortens.Under both operating modes, its function is all to reprint, that is, driving
Or return the mixed coal stepped on and reprint on subordinate's belt feeder.During driving operating mode, flexible train is reduced to the shortest, with reprinting after unit to broken
Face, with driving unit（Including broken elevating conveyor）Drilling depth and extend, general extension elongation is the drilling depth of two digging classes（200
Rice）When efficiency highest.Elongation operating mode：Steel truss train firmly grasp ground motionless, afterbody unmanned steering mechanism steel wire rope freely short with
Broken elevating conveyor midpoint connects, and when driving unit advances, pulls the navigation steel wire rope being connected with broken elevating conveyor, touches speed and passes
Sensor, material feeding navigation tractor live axle starts after receiving this signal, rearwardly direction running, at this moment, conveyor belt tension
Increase, after conveyor belt tension is more than range of set value, constant tension winch inverts, and enters pump work state, discharges steel wire rope, moves about
Dolly is retracted by adhesive tape, travels to heading, adhesive tape discharges, flexible train is elongated.Until flexible train and driving
Unit is synchronous, and when flexible train is very fast, when exceeding driving unit speed, velocity sensor contact inverts, material feeding navigation tractor
Live axle slows down after receiving this signal, until flexible train is synchronous with driving unit.In storage cassette holder, adhesive tape all stretches out
When, first carrying roller car touches limit switch, and material feeding navigation tractor live axle power-off is stopped, brake locking.Conveyor belt tension
When being reduced to range of set value, constant tension winch stall.Now just enter maintenance crew, need flexible train to shorten to the shortest shape
State, enters next circulation.Shorten operating mode：Its afterbody（Material feeding navigation tractor）Locking is motionless, and steel truss train oil cylinder is packed up,
Enter walking operating mode, live axle is energized, rearwardly direction running, promote the flexible train of elongation to shorten successively, now, adhesive tape
Lax, conveyor belt tension is less than setting value, and in storage belt storehouse frame, constant tension winch rotates forward,（Enter motor condition）Draw travelling little successively
Car, carrying roller car, to tail direction running, are drawn in lax adhesive tape in storage belt storehouse frame and are stored, shorten to the most in short-term, adhesive tape is no longer
Lax, when conveyor belt tension reaches range of set value, constant tension winch stall, travelling dolly, carrying roller car stop, in storage cassette holder
A carrying roller car touches limit switch afterwards, and live axle power-off is stopped, brake locking.Stretch out oil cylinder and hold out against ground, wheel from
Ground, leveling steel truss.Extend subordinate's belt feeder to overlap therewith, enter elongation operating mode（Driving operating mode）.So far, automatic telescopic belt
Machine completes once automatically to extend and automatically restores to driving operating mode, goes round and begins again, until crossheading driving finishes.
This shortens operating mode and automatic telescopic belt conveyer is compressed to short status by long status, and whole machine moves to tail direction
Move a distance of stretch out and draw back.Following this shortening operating mode is summarized as：During driving, automatic telescopic belt conveyer automatically resets and oneself
Dynamic walking.
Return when stepping on operating mode, flexible train is elongated to the longest, and head is reprinted with broken with subordinate's belt machine tail part overlap joint, afterbody
Machine overlaps, and steps on work surface drilling depth and shortens with returning.As the same in collapsing length, typically 12 to 20 meters of daily drilling depth, after about ten days,
Flexible train is reduced to the shortest, entrance maintenance crew.Shorten operating mode：Steel truss train oil cylinder holds out against ground and maintains static, and afterbody is unmanned
The steel wire rope free end of steering mechanism is connected with automatic pulverizing elevating conveyor midpoint, when automatic pulverizing elevating conveyor moves forward, steel wire
Rope is lax to be shortened automatically, after velocity sensor perceives this signal, controls material feeding navigation tractor driving means to heading
Travel, until synchronous with automatic pulverizing elevating conveyor, promote flexible train to shorten simultaneously,（Flexible train itself has guide function）,
Now adhesive tape relaxes, and conveyor belt tension is less than setting value, and constant tension winch rotates forward（Operation status of motor）, the travelling car of traction is to tail
Direction running, is stored in adhesive tape in cassette holder；When flexible train is very fast, when exceeding automatic pulverizing reprinting motor speed, speed passes
Sensor contact inverts, and material feeding navigation tractor driving means receive slows down after this signal, until with automatic pulverizing elevating conveyor
Synchronous.When in storage cassette holder, adhesive tape storage is full, limit switch touched by last carrying roller car, and material feeding navigation tractor driving means are disconnected
Electric parking locking, conveyor belt tension increases to setting value, constant tension winch stall.Now complete all to shorten operating mode, enter maintenance
Class, needs automatic telescopic belt conveyer to be adjusted to the longest operating mode, enters next circulation.Elongation operating mode：First by subordinate's belt feeder
Shorten, ground grading.Automatic telescopic belt conveyer afterbody is motionless, and steel truss train oil cylinder is packed up, unmanned steering mechanism steel wire rope connection
Connect subordinate's belt machine tail part midpoint, enter walking operating mode, to subordinate's belt feeder direction running, stretch the flexible train shortening, this
When conveyor belt tension be more than setting value, constant tension winch inverts, and enters pump work state, travelling car pulled to heading by adhesive tape,
Carrying roller car is drawn close automatically, storage cassette holder release adhesive tape, moves to the longest, spacing driving touched by first carrying roller car when adhesive tape all discharges
Close, steel truss train power-off, parking locking, in storage cassette holder, adhesive tape all discharges, and conveyor belt tension is reduced to setting therewith
Value, constant tension winch stall.Its head and subordinate's belt feeder tail overlap joint, steel truss train stops, stretches out oil cylinder and holds out against ground
Face, wheel lift, leveling steel truss, enter and shorten operating mode.So far automatic telescopic belt conveyer completes once automatically to shorten and automatic
Return to back and step on operating mode.Go round and begin again, until exploiting field completion.
This elongation operating mode elongates long status automatic telescopic belt conveyer by short status, and whole machine moves to heading
Move a distance of stretch out and draw back.Following this elongation operating mode is summarized as：Return automatic telescopic belt conveyer when stepping on automatically reset and from
Dynamic walking.
Steel truss train operating mode：1st, steel truss train driving is adopted on road surface in machine, and its irregularity degree is that three meter rulers are maximum high
Differ from 100 millimeters；When the 2nd, tunneling operating mode, steel truss train travels to tail, is guided it is ensured that its straight-line travelling by flexible train, makes
Automatic telescopic belt conveyer returns to the shortest（Driving operating mode）, and travel a distance of stretch out and draw back to tail direction；3rd, return and step on operating mode
When, steel truss train travels to subordinate's belt feeder, is navigated it is ensured that its straight-line travelling by unmanned steering mechanism, makes Expansion belt conveyor
Return to the longest（Return and step on operating mode）, and heading travels a distance of stretch out and draw back；4th, UNICOM's oil pipe hangs all oil cylinders
Compensating cylinder UNICOM, after the corresponding steel truss gun carriage load adjustment of compensating cylinder cylinder diameter, in the case of pavement roughness, steel truss is one
It is ensured that travelling dolly and carrying roller car normally travel on individual nearly horizontal plane.
In sum, although having navigation before steel truss train, after have guiding, under the influence of pavement roughness, row
Car still crawls error, and this error is due to steel truss gun carriage unbalance loading, and two resistance wheels are unequal to be caused.In this work
Under condition, it is relatively difficult that this error is completely eliminated, but reduce this error reach application target be easier realize.Therefore steel
