The A preparatory stage

The development machine transportation puts in place, and hydraulic system 2.6, electric-control system 2.5 all start and carry out self check, and detection, monitoring and warning device are all opened.

By tunnel interior orientation laser is detected, and the detection computations result fed back to the Industrial Personal Computer (IPC) of electric-control system 2.5, manually-operated running part 1, support portion 2, back, shovel board portion 7 adjust then, guarantee that the development machine stand aligns with the tunnel center line.At this moment, body horizontal support 4.6, back support level support 2.1, shovel board portion 7 and support portion, back ground supports 2.4 support to place, and guarantee when development machine breaks rock work steady.

Section checkout gear in the electric-control system carries out comprehensive scanning to the tunnel work plane, Industrial Personal Computer (IPC) is according to whole shapes of detected tunnel work plane and positional information, automatically write down the size and the shape in tunnel, major parameter according to operator's input calculates boring distribution form (as shown in Figure 6) again, and the planning of the track of holing, the course of work, and describe to the operator by display unit; The operator judges that track is reasonable, automatically calculate in the course of work attitude information in each each joint of the arm of rock drilling constantly and corresponding with it hydraulic system, the controlling parameter of electric-control system by the operation Industrial Personal Computer (IPC) again, preserve all information and form operational order, wait pending.

The operator moves to the front end extreme position by the slide unit 4.1 on the operating desk 4.2 control bodies 4, Industrial Personal Computer (IPC) calculates brokenly the home of rock arm 6.2 according to the attitude information of rock drilling track and rock drilling arm, interfere with rock drilling arm 5.2 in the boring procedure preventing, preservation information, be converted into control instruction and carry out, electricly move to the home that calculates with the broken rock arm 6.2 of hydraulic means control.The display interface of operating desk as shown in Figure 7 during boring.

The B rock drilling stage

Industrial Personal Computer (IPC) accesses control instruction and passes to PLC from control module, PLC control rock drilling arm 5.2 is carried out boring work, boring procedure full automatic working.The pressure of the drill of propeller 5.4 advances the oil cylinder working-pressure transmitter to detect by propeller, regulates by hydraulic system.The ballistic work height of hydraulic gate 5.3 is regulated by hydraulic system pressure and is realized.Water is cooled off and chip removal drill steel.

The antecedent condition that Industrial Personal Computer (IPC) calculates drilling track automatically is to avoid three rock drilling arms 5.2 to run foul of each other; but still to monitor the locus of each arm in the boring procedure in real time; in case the possibility of collision occurs; automatically protect at once; stop current boring work, seek next suitable bore position and recomputate drilling track.

Can prop up crag in order to ensure rock drilling arm 5.2 propellers 5.4 holes smoothly, setting pressure transmitter monitor force changes on the propeller compensating cylinder, and pass to controller and judge whether to prop up crag, if unusual rock drilling arm 5.2 shrinks immediately, seek bore position feeding once more, boring again;

Boring work can be divided into perforate and two stages of boring, hydraulic gate 5.3 is with low-power, low frequency of impact constant speed perforate when carrying out perforate work, propeller 5.4 advances with low the pressure of the drill, can judge whether the perforate success by the radial pressure transmitter that propeller front end clamper place is provided with.If the perforate success enters the boring stage, control system is regulated parameter automatically makes hydraulic gate 5.3 with total power, HI high impact frequency, the boring of permanent drilling speed.If the guard process that pre-sets is carried out in boring failure, control system propeller 5.4 is recalled, reorientated, perforate.Each component locations of boring procedure and attitude are as shown in Figure 9.

Because operating mode and condition during hydraulic gate 5.3 borings are disliked slightly very much, a large amount of dusts of generation and rubble are often owing to chip removal does not make freely that " card pricker " phenomenon appears in hammer drill 5.3.Equally, can judge whether occur " card pricker " in the boring procedure by pressure transmitter.If " card pricker " is serious, then propeller 5.4 bounces back automatically, and hydraulic gate 5.3 stops automatically impacting but continues revolution, until unfreezing; If " card pricker " phenomenon is slight, can suitably reduce the pressure of the drill of propeller 5.4.

After each boring finished, Industrial Personal Computer (IPC) was by the PF cylinder pressure fast return of PLC control propeller 5.4, and hydraulic gate 5.3 stops to impact, and revolution and cooling water continue to retreat to extreme position until propeller 5.4.After the fast return, seek next boring point and repeat above boring procedure, finish until all drillman according to predefined track.Whether boring work is finished can be judged that the operator also can artificially monitor by monitoring, the logging program of control system.After boring work was all finished, Industrial Personal Computer (IPC) accessed and calculates good rock drilling arm 5.2 safe placement locations in advance, and control system drives hydraulic actuator moves into place rock drilling arm 5.2.

C breaks the rock stage

Break rock arm 6.2 work tracks and adopt zoning plans, Industrial Personal Computer (IPC) can take into full account the anticollision problem when the rock track is broken in calculating automatically, make the track that obtains reasonable as far as possible.Industrial Personal Computer (IPC) accesses from control module and calculates good broken rock arm 6.2 movement locus in advance, each degree of freedom increment of motion of broken rock arm 6.2 each moment attitude correspondence is changed into control instruction and passes to PLC, and PLC controls brokenly rock arm 6.2 by electric-control system 2.5, hydraulic system 2.6 and carries out work.Broken rock process is similarly full automatic working, judges brokenly the various operating modes of rock according to the state of quartering hammer PF cylinder pressure pressure transmitter, thereby implements different operations.Hydraulic breaking hammer 6.3 can not be above 10 seconds at the impact duration of same position.The ballistic work height of hydraulic breaking hammer 6.3 can be regulated the adjusting nut of hydraulic breaking hammer 6.3 sidepieces and realize.In the broken rock process water spray dust suppression device 6.5 constantly water spray to drill steel cool off, dedusting.

After broken rock arm 6.2 put in place, telescopic oil cylinder was overhanging, and hydraulic breaking hammer 6.3 compresses crag.Can compress crag in order to ensure broken rock arm 6.2 and break rock work smoothly, advance setting pressure transmitter monitor force variation on the oil cylinder, judge according to detected force value whether quartering hammer 6.3 compresses crag at broken rock arm 6.2.The pressure judgment value must be considered the component that 6.3 body weight of quartering hammer produce in the advancing hydraulic pressure direction.Computational process is finished by Industrial Personal Computer (IPC), and angle is measured by inclinator.If unusual, broken rock arm 6.2 shrinks immediately, seeks rational position again and compresses crag once more.Broken each component locations of rock process and attitude are as shown in figure 10.

Hydraulic breaking hammer 6.3 circulation impacts break rock, and broken rock arm 6.2 advances oil cylinder to keep constant pressure.Hydraulic breaking hammer 6.3 begins to carry out the work of impact cutting rock after compressing crag, utilizes timer to determine that single-point impacts duration, by judging brokenly that rock arm 6.2 advances the stroke of oil cylinder whether to reach capacity definite this time broken rock to impact and whether finishes.If broken rock duration reaches capacity greater than 10 seconds, PF cylinder pressure stroke, decidable impact cutting rock success this time, the hydraulic cylinder retraction is sought next impact position according to setting track; If broken rock arm 6.2 each joint freedom degrees amplitude of variation are excessive, can think and produce big slippage between tup and the crag, this moment, hydraulic cylinder bounced back immediately, repeat the location of this location point, broken rock work, if produce slippage once more, control program automatically with this location point deletion, jump to the next position point and carry out the impact cutting rock.

Broken rock arm 6.2 is according to track and the broken rock of control program repeated stock, and laser detector is monitored in real time to the broken rock degree of depth.If the broken rock degree of depth of whole tunnel work plane reaches 800mm, Industrial Personal Computer (IPC) judges that automatically this impact cutting rock circulation finishes, and body slide unit 4.1 retractions prepare to carry out rewinding work.

The D rewinding stage

Industrial Personal Computer (IPC) control electric-control system 2.5, hydraulic system 2.6 make body horizontal support 4.6, back support level support 2.1 and all regain, and a fortune portion 3 motors and shovel board portion 7 star-wheel motor runnings begin to carry out rewinding, haul work.Can utilize brokenly recovering hopper 6.4 on the rock arm 6.2 to assist rewinding in the rewinding process, improve rewinding efficient.Rewinding is carried out in 7 liftings of shovel board portion, running part 1 reach.The operator judges whether rewinding work finishes, and the manually-operated Industrial Personal Computer (IPC) jumps to step (2) if rewinding finishes then, carries out next working cycles.By tape deck and checkout gear, the broken rock cycle-index of record and total broken rock footage drilled if the broken rock degree of depth of accumulative total reaches 3300mm, stop brokenly the rock circulation, go on foot work once.Each component locations of rewinding process and attitude are as shown in figure 11.

E back chipping, bolt support stage

When the broken rock degree of depth of accumulative total reaches 3300mm, body 4 slide unit cylinder pushes slide units 4.1 retractions, body horizontal support 4.6, back support level support 2.1 and all regain, the broken 6.2 pairs of tunnel work planes of rock arm of Industrial Personal Computer (IPC) control carry out finishing process, guarantee cross section, tunnel quality, for next working cycles is prepared.The operator judges back chipping after hours, and Industrial Personal Computer (IPC) accesses the bolt support program, finishes to assist according to three rock drilling arms of track use and plays anchor pole work, and the course of work is consistent with broken rock process.After finishing, all processes enters next work systemic circulation.Each component locations of bolt support process and attitude are as shown in figure 12.

The entire work process flow process as shown in Figure 8.
