Compared with prior art, the present invention has technique effect beneficial below：
Hydraulic support of the present invention moves frame method and adapts to the soft condition of floor undulation automatically, unlike existing skill
Art first carries out the action of lift bottom and carries out shifting frame action again like that, but lift bottom and the action of shifting frame are carried out parallel, i.e., in the same of lift bottom
Shi Jinhang moves frame, carries out the action of lift bottom during moving frame in other words always, frame is moved while lifting bottom, enhances lift bottom and moves
The cooperation of frame, makes entire hydraulic moving stand form the process gone up a slope, and this method makes hydraulic support height gradually increase, makes
Obtain the phenomenon that hydraulic support frames foot does not reach bottom plate during moving frame, reduces coal piling during moving frame.
Further, due to move frame action quickly, for avoid due to move frame action fulfil ahead of schedule reduce lift bottom action and
The mutually matched effect of frame action is moved, during moving the total travel of frame, frame action at least pause will be moved once, it is temporary to move frame action
The action of lift bottom continues during stopping, and bottom action is lifted at the end of moving frame stroke with guarantee can carry out time enough, can make liquid
Pressure holder rises to enough height, and entire holder is made to move the process that frame forms ladder, reduces showing for coal piling during moving frame
As.
Further, since bottom plate situation is not quite identical, the speed for moving frame every time is also just not quite identical, in order to ensure
Other production processes can be normally carried out, and preset a shifting frame actuation time, at the end of moving frame actuation time, no matter it is dynamic to move frame
Work is covered either with or without by total travel, will stop moving frame action, to ensure that subsequent process can be normally carried out, in order to avoid delay whole
Body progress.
Further, whether drop column reaches the pressure i.e. column pressure of column and top plate that drop column effect is detected by pressure gauge
Judge, the default drop column time for the first time drops the column time, drops column time and expecting pressure value again for the first time, is dropped column for the first time, head
At the end of the secondary drop column time, if the pressure value that pressure gauge is shown is more than expecting pressure value, then is dropped column action, until reaching
Column effect drops to expected, and when ensureing the action of lift bottom, hydraulic support can be raised to certain altitude, and heap is reduced when in order to move frame
Coal phenomenon.
Description of the drawings
Attached drawing 1 is that the present invention moves frame process control flow figure.
Specific implementation mode
With reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
A kind of hydraulic support for broken bottom plate moves frame method automatically, by increase during moving frame " frame is moved to suspend,
Bottom is lifted to keep " function, repeatedly pause shifting frame acts during moving frame, and suspends lift bottom holding during moving frame action, makes hydraulic pressure
The phenomenon that holder shifting frame forms step process, reduces coal piling during moving frame.
Referring to attached drawing 1, the present invention executes the automatic frame that moves using bracket controller and controls operation sequence, is as follows：
The first step is drop column step：Bracket controller executes the automatic drop column step moved in frame program；It is default to drop column for the first time
Column time and removable frame pressure drop in the time again, drop column action for the first time are carried out, at the end of dropping the column time for the first time, if column pressure
Power is less than or equal to removable frame pressure, then drops column action and terminate, column action is otherwise dropped again, at the end of dropping the column time again
Drop column action terminates；The preset drop column time for the first time is T1, T1=0.5-5s, it is T to drop the column time again2, T2=0.5-5s, can
Shifting frame pressure is P1, P1=0-20MPa；
Second step is to move frame step：After dropping column action, hydraulic support, which executes, moves frame；It is default to move frame actuation time and temporarily
Stop stroke, while carrying out the action of lift bottom and shifting frame action parallel, is i.e. the lift bottom action time started and shifting frame acts time started phase
Together, the lift bottom action end time is identical with the frame action end time is moved；When hydraulic moving stand reaches pause stroke, it is dynamic to move frame
Make pause a period of time, lift bottom function is always maintained at so that support height gradually increases so that support foot connects in shifting frame process
It touches less than bottom plate；At the end of moving frame actuation time, the action of lift bottom and shifting frame action terminate；Preset shifting frame actuation time is
T3, T3=5-120s；It is T to move the time that frame action suspends every time4, T4=0.5-2s；
Third step is setting prop step：After lifting bottom action and moving frame action, start to execute setting prop action, setting prop is completed
Afterwards, entire automatic frame process of moving terminates.
In preferred embodiment of the present invention, T1=3s, T2=2s, P1=8MPa, T3=10s.
Drop column in the first step of the present invention whether reach the pressure of column and top plate that drop column effect is detected by pressure gauge come
Judge, if the not up to expected drop column action effect of drop column, makes drop column not reach the scheduled drop column amplitude of program；Program starts reality
Row drops column process again until drop column achieves the desired results.In practical situations, once expected drop column effect may be not achieved in drop column,
Therefore the drop pillar height degree by " dropping column again " function reduction hydraulic support is needed so that hydraulic support can be by hydraulic support when lifting bottom
The higher of lift reaches expected drop column action effect.
In second step of the present invention, the pause stroke for moving frame action is controlled by parameter suspending count, if suspending count is N
It is secondary, then it will move frame total travel and be equally divided into N+1 sections of strokes, when hydraulic moving stand to position between every adjacent two sections of strokes
Move frame pause in action for a period of time.This example, hydraulic moving stand total travel is 960mm, if suspending count is set as primary, temporarily
It is 480mm to stop stroke, i.e. hydraulic support moves frame to 480mm time shift framves pause in action for a period of time from 960mm；If suspending count
It is set as twice, then it is respectively 640mm and 320mm to suspend stroke.In preferred embodiment of the present invention, suspending count is that three times, will move frame
Total travel is equally divided into four sections of strokes, hydraulic moving stand to the position time shift frame pause in action one between every adjacent two sections of strokes
The section time, that is, it is respectively 720mm, 480mm and 240mm, each time out T to suspend stroke4=1s.
In second step of the present invention at the end of preset shifting frame actuation time, walked either with or without by total travel no matter moving frame action
It is complete, it will stop moving frame action, 960mm total travels are not covered into the action of lift bottom and must be stopped if moving frame action even if moving frame
Only, it just can guarantee that subsequent process can be normally carried out, and will not delay overall progress in this way.
The present invention will lift bottom and move the parallel progress of frame action, i.e., carry out shifting frame while lifting bottom, move the mistake of frame in other words
The action of lift bottom is carried out in journey always, frame is moved while lifting bottom, enhance lift bottom and moves the cooperation of frame, meanwhile, moving frame action
Increase in the process and move frame pause in action process, bottom action is lifted during moving frame pause in action and is continued, to ensure to move frame stroke knot
Bottom action is lifted when beam can carry out time enough, entire to move frame process knot to ensure that hydraulic support is made to rise to enough height
Shu Hou, makes entire hydraulic moving stand form the process of ladder, and this method makes hydraulic support height gradually increase so that
Hydraulic support frames foot does not reach bottom plate during moving frame, hydraulic moving stand mistake in the case of effective solution bottom is broken
In journey before frame the problem of coal piling, the requirement that working face in the pit uses can be met.
The above, the preferable specific implementation mode of patent only of the present invention, but the protection domain of patent of the present invention is not
