During use, Closing Switch K, a grip that holds the housing tail end, make the left side of jaw assembly, right caliper body places two crossover sites both sides that wire lath is to be connected, with a left side, gangbar between right caliper body is pushed up mutually with crossover sites, make a left side, the right caliper body closure, scratch the spanner of moving grip with hand, what handle was interior responds to conducting near K switch 1, relay J 1 coil is instantaneous to be got, its constant open contact J1-1 adhesive forms self-locking, make relay J 1 keep electricity condition, its another constant open contact J1-2 adhesive simultaneously, two position two-way valve F1 gets electric connection, and source of the gas enters an into air motor by two position two-way valve F1 and two-position five-way valve F2 in turn, advancing an air motor realizes just changeing, and the active that drives the advance and retreat silk device advances a high-speed gear rotation, and iron wire is through the principal and subordinate and moves in the inlet wire groove of a gear into, moves the principal and subordinate under the traction of a gear into by what advance that fiber tube arrives that gib head assembly fixed support body walks fiber tube and advances silk mouthful; Advance an air motor and continue rotation, iron wire is walked fiber tube in the promotion lower edge of advancing a gear and is continued into silk.Pass the fiber tube of walking of gib head assembly when iron wire, its head inserts and the walking in the hook groove on the relative movable gib head of fiber tube of gib head assembly, the forward motion always of iron wire, the movable hook crown is opened, and become bifilar, enter the wire chamber of left and right caliper, move, be wrapped in wire lath and treat point of attachment along the directive wheel in the left and right caliper wire chamber; Simultaneously, when relay J 1 electric the time, counting relay JC1, JC2 also electric, export for next step counting and to prepare; When bifilar iron wire arrived the L shape dead man place at jaw assembly place, the iron wire of motion was stirred dead man and is moved downward, and the connecting rod that dead man one end is fixed with the magnetic iron block moves, and makes the magnetic iron block with relative near K switch 2, near K switch 2 induction conductings; Relay J 2 coils are instantaneous to be got, its constant open contact J2-1 adhesive, form self-locking, make relay J 2 keep electricity condition, its two constant open contact J2-3 and J2-2 adhesive in addition, the adhesive of J2-3, make two-position five-way valve F2 get electric commutation, advance an air motor reverse rotation, by advancing the counter-rotating draw of a gear, make to be bundled in wire lath and to treat that the iron wire of point of attachment retracts and take out tightly, take out tight the time bifilar iron wire hook on movable gib head; And the J2-2 adhesive time, time relay JT1 also must establish the beginning timing by cable, the time of control motor reverse rotation (this time is by the setting decision of time relay JT1), after timing time arrived, the constant close contact JT1-1 of time relay JT1 disconnected, constant open contact JT1-2 gets electric closure, constant close contact JT1-1 disconnects, and makes two position two-way valve F1 dead electricity, advances an air motor stall, make iron wire tightly be wrapped in two online, wholely advance the silk action and finish; Constant open contact JT1-2 gets electric closure, two position two-way valve F3 gets, source of the gas is connected, in turn by two position two-way valve F3 and two-position five-way valve F4, the clot air motor drives clot mechanism through shaft coupling and is rotated in the forward, and at this moment, rotary body rotates with respect to fixed support block, the fiber tube of walking that connects when each parts is in initial position on it staggers mutually, walks iron wire in the fiber tube and is squeezed and cuts off automatically.When the gib head assembly rotates a circle under the driving of clot air motor, the disk of shaft coupling also rotates a circle, magnetic iron block on it makes near K switch 3, the K4 induction is connected once, output signal to the instantaneous contacts JC1-2 of counting relay JC1 and JC2, JC2-2, instantaneous contacts JC1-2, the JC2-2 closure once, each counting of counting relay JC1 and JC2 once, when the gib head assembly rotates a few, iron wire will be reversed a few (suppose gib head assembly revolve turn around half), near K switch 3, K4 responds to respectively three times, counting relay JC1 and JC2 counting three times, count number full (set point number of supposing counting relay JC1 is 3 times), counting relay JC1 coil gets, its constant open contact JC1-1 adhesive, two-position five-way valve F4 gets electric commutation, clot air motor commutation reverse rotation, movable gib head is by deviating from the bifilar iron wire, and an iron wire that is embedded in the movable gib head hook groove will advance thread the time withdraws from; Clot air motor reverse rotation one circle half, continue induction three times near K switch 4, counting relay JC2 counting six times, count number full (set point number of supposing counting relay JC2 is 6 times), counting relay JC2 coil gets electric, and its constant close contact JC2-1 disconnects, time relay JT2 coil losing electricity, its constant open contact JT2-2 dead electricity disconnects, whole electric control circuit dead electricity, all pneumatic operated valves and relay all reset; The one-step bundling process finishes, and catches enforcement main frame handle to be pulled outwardly and can a little to recall the enforcement main frame from tying up.Simultaneously, since counting relay JC2 coil losing electricity, its constant close contact JC2-1 closed reduction, time relay JT2 coil is instantaneous again to be got, behind the time-delay 0.2s (this time is by the setting decision of time relay JT2), its constant open contact JT2-2 closure is tied up actuation cycle for the next one and is got ready.In addition, after the stall of clot air motor because inertia, make its can not be in time, stop apace, when motor continues the rotation of little moment of torsion under effect of inertia, under the effect of torsion spring, little cam applies certain resistance on heart-shaped big recessed wheel the on the clot mechanism rotary body, prevents big recessed the wheel to continue rotation, because big recessed the wheel is heart, make little cam be stopped at heart-shaped big recessed recess of taking turns exactly, finally make the gib head assembly in time, stop operating apace, and reset accurately.Compared with prior art, the mode that the utility model adopts electricity, gas control system to combine is implemented in the down-hole and connects wire lath fast, in high quality, for the down-hole bolting with wire mesh implements to provide condition.Described is existing known products one proximity Hall switch near switch.
The utility model is reasonable in design, and is simple in structure, easy to use, significantly reduced labor strength, improves networking speed and networking efficient, accelerates the fltting speed of fully-mechanized mining working.
