Background technology
Hydraulic support is the works for controlling coal-face mine pressure.Adopt the form effect carried beyond the ore deposit pressure of face
On hydraulic support.In hydraulic support and adopt in the mechanical system of face country rock interaction, if each supporting member of hydraulic support is closed
The outer load that power and top plate are acted on hydraulic support is made a concerted effort just same straight line, then that face country rock is adopted to this is very suitable for the hydraulic support
Should.Hydraulic support, is a kind of a kind of proper noun of metallurgy subject.Hydraulic support is for controlling coal-face mine to press
The works of power.The form carried beyond the ore deposit pressure of face is adopted to act on hydraulic support.Interacted in hydraulic support with face country rock is adopted
Mechanical system in, if each supporting member of hydraulic support is made a concerted effort, the outer load that is acted on top plate on hydraulic support is made a concerted effort just same
Straight line, then the hydraulic support face country rock is adopted to this and is extremely adapted to.The development of China's hydraulic support since early 1970s
Work, basic condition is very poor, and all are all started from scratch, and required sheet material, tubing and hydraulic tube glue etc. are required for developing and tried
Test.70 type step type automatic shifting stands were designed by Taiyuan branch and Zhengzhou Mei Ji factories in 1964, from that point on the state of hydraulic support
Productionization road.Under the dint of hard work of numerous scientific workers, pile formula, Jie Shi and shield successively have developed.Although
The Performance And Reliability of these supports is all poor, but is laid a good foundation for the development of China's hydraulic support, have accumulated experience.From upper
The mid-90 in century, China's hydraulic support enters the stage of fast development.This period fully mechanized mining technology is promoted, entirely
The fully-mechanized mining working quantity of state has increased significantly, while the performance of hydraulic support, technical parameter, stability and can
Obvious raising is there has also been by property, the frame type of support constantly enriches.The particularly successful application of caving Mining Technology, significantly
Ground has promoted the fast development of caving roof coal hydraulic support.The frame type of caving roof coal hydraulic support by put coal position point have a high position, middle position,
Low caving coal hydraulic support；There are positive double leval jib and reverse-four-link-bar sublevel caving hydrau lic support etc. by four company directions to divide.Liquid of the prior art
Support is pressed during coal mining, it is difficult to the spoil being collected into is taken to filling position from low to high, if introducing single container
And lowering or hoisting gear takes the spoil being collected into filling position from low to high, the increase of cost, operating efficiency are not only resulted in
It is not high, moreover, the bad adaptability of the container and elevating mechanism and hydraulic support of the prior art introduced, in addition it is also necessary to expend more
Human resources.In Patent No. CN201410257551 patent document, a kind of hydraulic support is disclosed.The hydraulic support
Scratch board conveyor including the main part with base, the afterbody for being connected to base, scratch board conveyor include top plate, bottom plate,
And be connected to the side wall between top plate and bottom plate, formed between top plate, side wall and bottom plate offered on storage tank, top plate it is some
The individual waste coal hole passed through for the spoil caused to fall and break, scratch board conveyor is driven by chain-drive mechanism, in addition to material-receiving system, feeding
Device and ramming mechanism, material-receiving system are contained in storage tank, feeding device have be installed on material-receiving system afterbody low side and
Relative with low side is high-end, for the spoil that low side is delivered to by material-receiving system to be delivered into high-end, ramming mechanism by low side
It is connected to the afterbody of material-receiving system.The main part integration of the material-receiving system and feeding device and hydraulic support is good.
Above-mentioned patent document can be collected to be fallen on scratch board conveyor bottom plate by waste coal hole on scratch board conveyor top plate
Spoil, and it is fallen near the low side of feeding device, feeding device will be delivered to the spoil of low side by material-receiving system by low side

Beam, if during F.F. or work are entered, pressing and retracting button SB2, slide unit will be retracted quickly to be stopped behind original position, is being grasped manually
Make under mode, change-over switch SA is closed to " manual " position, if pin start button SB1, working slider feed motion；If
Press and retract button SB2, slide unit, which will be returned to quickly behind original position, to be stopped.
6. the multifunctional intellectual mine hydraulic support according to claim 1, it is characterised in that：The communication interface circuit is adopted
It is in order to eliminate the interference from zero line, so as to ensure the reliability of data communication with the purpose of optical coupling isolation circuit；RS-485
Bus driver use 65ALA1176 models driving chip, 12Mbps transmission rate can be met, its side by optocoupler with
SPC3 is connected, and opposite side is connected with 9 pin D connectors, and is connected by 9 pin D connectors with PROFIBUS-DP networks,
SPC3 and M, 2M in RS-485 interface circuit are different power supplys, and P5,2P5 are 2 groups of not+5V power supplys on ground altogether.
7. the multifunctional intellectual mine hydraulic support according to claim 1, it is characterised in that：Including break alarm circuit,
The break alarm circuit is used to judge hydraulic support with the presence or absence of the wrong or antitheft of excessively elongation or position, when touching is disconnected
Alarm signal can be produced when line.
8. the multifunctional intellectual mine hydraulic support according to claim 7, it is characterised in that：In the break alarm circuit
Bias voltage is provided for BG1 b poles by R1, under the state of alert, b poles bias voltage is through warning line S shorted to earths, BG1 not works
Make, S is disconnected, BG1 immediately electric work, BG1 emitter currents turn on through R2 triggerings SCR, and indicator lamp LED is bright, and IC outputs are alarmed
Signal, after the compound amplification of BG2, BG3, drive the speaker playback, even at this moment S is reclosed, is not also missed, only according to report
Alarm could be released by turning off the power switch, so with tamper-proof effect.
