As Fig. 1, Fig. 2, shown in Figure 3, an auxiliary girder 5 that detachably is spliced by two sections of d, f also is housed in a side of a girder 4 of former hoisting crane, detachable splicing is formed at one side two ends of auxiliary girder 5 and side two ends of a girder 4, two secondary trolley tracks 10,11 that are parallel to girder two main carriage tracks 8,9 are respectively arranged on auxiliary girder 5 and the adjacent girder 4 thereof, a secondary dolly 3 that can move on two secondary trolley tracks 10,11 forms crane in bridge type.
As Fig. 4, shown in Figure 5, if will be assembled into transfer crane, then between the two ends of two girders 4,7 and cart roller 6, supporting leg is housed respectively.
As shown in Figure 3, intersegmental at a, the c two of two girders 4,7, splicing has two main carriage tracks and a secondary trolley track detouchable b section respectively; D, f two at an auxiliary girder 5 are intersegmental, and splicing has a secondary trolley track detouchable e section respectively, forms three beams, three dolly bridge-types, the transfer crane of variable span.
As Fig. 6, shown in Figure 7, base frame face 19 at main carriage and secondary dolly is equipped with respectively by left-hand door 20 and right door 23 dodge gates of forming, and foot guard plate 17 is equipped with in the left side of its left-hand door 20, and railing 21 is equipped with on the right side, connecting rod 15 is equipped with in the bottom, and diagonal angle of left-hand door supports with connecting rod 16; Foot guard plate 13 is equipped with on right side of its right door 23, and the junction g of left side and right door 23 is equipped with pivotally attached railing 22, and the other end that blocks bar 22 is hinged with the junction h of railing 21 1 ends of left-hand door, and diagonal angle of right door is with connecting rod 14 supports.Pulling left-hand door handle 25 and right door handle technology 26, the left-hand door 20 of dodge gate and right door 23 are opened above the base frame face of dolly around left-hand door hinge 18 and right door hinge 24 respectively, as shown in Figure 8, just form a guardrail all around this moment naturally, so that guarantee maintainer's personal safety.
As shown in Figure 9, three phase frequency changing power AC contactor K1 in parallel, K2, the K3 that comprises the mouth of three-phase voltage source frequency converter B in electric box connects the operation motor M 1 of main carriage 1, the operation motor M 2 of main carriage 2, the operation motor M 3 of secondary dolly 3 respectively; The input termination three phase worker power of three-phase voltage source frequency converter B and AC contactor K4 in parallel with three phase worker power, K5, K6 meet the electromotor brake Y2 of main carriage 1 electromotor brake Y1, main carriage 2, the electromotor brake Y3 of secondary dolly 3 respectively, the low-voltage circuit breaker on QF1 among the figure～QF7 difference circuit.
Three beams, three dolly hoisting cranes adopt PLC as the control core, and big trolley body adopts frequency control, and lifting mechanism adopts the eddy-current brake speed governing.The lifting of these hoisting crane three dollies and translation can single movements, can link in twos, also can three interlocks together.During interlock, each dolly keeps synchronously, and when stopping even there being a dolly to hinder for some reason, other dollies also stop automatically at once.
Owing to used voltage source frequency converter, frequency converter output can drag multiple electric motors.Therefore 3 vehicle motors of native system translation frequency converter traction just have seven kinds of operating modes.The selection of operating mode realizes that by the change-over swith on the operator's station these seven kinds of operating modes are respectively: 1) No. 1 main carriage action; 2) No. 2 main carriage actions; 3) No. 3 secondary dolly actions; 4) No. 1, No. 2 main carriage interlocks; 5) No. 1 main carriage, No. 3 secondary dolly interlocks; 6) No. 2 main carriages, No. 3 secondary dolly interlocks; 7) No. 1, No. 2 main carriages, No. 3 secondary dollies link together.The principle of work of these seven kinds of operating modes is tiltedly stated as follows:
(1) No. 1 main carriage action
When the change-over swith on the operator's station was got to this operating mode, contactless switch K1 connected among Fig. 9, and K2, K3 disconnect.A frequency converter B output drive motor M1.
(2) No. 2 main carriage actions
When the change-over swith on the operator's station was got to this operating mode, contactless switch K2 connected among Fig. 9, and K1, K3 disconnect.A frequency converter B output drive motor M2.
(3) No. 3 secondary dolly actions
When the change-over swith on the operator's station was got to this operating mode, contactless switch K3 connected among Fig. 9, and K1, K2 disconnect.A frequency converter B output drive motor M3.
(4) No. 1, No. 2 main carriage interlocks
When the change-over swith on the operator's station was got to this operating mode, contactless switch K1, K2 connected among 9 figure, and K3 disconnects.Frequency converter B output drive motor M1 and M2.
(5) No. 1 main carriages, No. 3 secondary dolly interlocks
When the change-over swith on the operator's station was got to this operating mode, contactless switch K1, K3 connected among Fig. 9, and K2 disconnects.Frequency converter B output drive motor M1 and M3.
(6) No. 2 main carriages, No. 3 secondary dolly interlocks
When the change-over swith on the operator's station was got to this operating mode, contactless switch K2, K3 connected among Fig. 9, and K1 disconnects.Frequency converter B output drive motor M2 and M3.
(7) No. 1, No. 2 main carriages, No. 3 countermark dollies link together
When the change-over swith on the operator's station was got to this operating mode, contactless switch K1, K2, K3 all connected among Fig. 9.Frequency converter B output drive motor M1, M2 and M3.
Because the motor speed and the reduction ratio of three dollies are identical, take from same frequency conversion voltage source signal again, so keep synchronously during interlock.If in the coordinated operation process, there is a dolly to detect fault and stops, frequency converter B output is blocked at once so, and other dollies also stop at once.
The utility model is compared with background technology, and the useful effect that has is:
1) adopt two main carriages and secondary dolly with the change-over switch of electric box can with the separate unit trolley travelling or Many the heavy and overlength parts of the various composite sync operation of dolly hoisting weight;
2) adopt the detachable crane that splices span, can satisfy the requirement of construction site width and size;
3) crane of the detachable span of employing and leg is adapted at the inside and outside needs of constructing of Tunnel, both can Make the variable span bridge crane, can make again to become the span gantry crane and use, accomplish a tractor serves several purposes;
4) dodge gate of dolly base frame face is opened rear natural form guardrail all around, during maintenance trolley, guarantees Maintenance personal's personal safety.
