The real-time status of whole system is shown, makes system condition visual in image, equipment state is very clear, and integrated operation is simply easy
Learn, operational control is safe and reliable.
The integrated control computer of many hoist engines 10 is the main control computer for being assigned with large-scale LCDs, using desk-top or
Portable microcomputer.Main control computer is by EPA 11 and the multiple single hoist engine operating console 8 in system
It is connected, main control computer adopts graphical controlling interface, shows each hoist engine and the whole series in system under this interface in real time
The running status at each position of trailer system, here control environment under, main control computer both can Synchronization Control whole system whole
Hoist engine, each hoist engine that again can individually in control system, so as to before system wide synchronized is run, to system in per platform
Hoist engine carries out state setting so as to meet the conditions dictate of synchronous operation.
The work flow of various construction technologies：
1st, the reciprocating synchronous traction system control flow of single line：The reciprocating sync pulling construction technology of single line is general to adopt
Two hoist engines one between two anchorage of suspension bridge are received, a single haulage cable of drawing of being rivals in a contest is realized.Before starting traction, first
Two hoist engines, two haulage cables utilizations are pulled into device and connects into one, adjustment pulls device has trailed steel wire to storage
The hoist engine side of rope；Two rack winches positioned between two anchorages start simultaneously, and speed equidirectional is contrary.Single line is reciprocal
Formula sync pulling work flow is as follows：Device will be pulled and be adjusted to corresponding start position, and with installed in putting, rope is in-house to be led
Draw erection cat road track cable（Or main push-towing rope）Front end anchor head is connected → two rack winches of synchronous averaging temporarily（One receipts
Rope, another put rope）→ low speed goes upward to king-tower top across cable saddle door frame guide wheel group → sync plus white is dissipated to hauling speed is allowed
Preamble deceleration → low speed in portion's, is close to allowing hauling speed to cross over main span by door frame guide wheel group → sync plus white at the top of king-tower
Opposite king-tower front reduction gear → low speed, is come downwards to hauling speed is allowed by door frame guide wheel group → sync plus white at the top of the king-tower of opposite
Opposite dissipates cable saddle front reduction gear → low speed and is drawn by dissipating cable saddle door frame guide wheel group → stoppings, being led cat road track cable in place
（Or main push-towing rope）Front end anchor head is anchored with the connection of corresponding anchor system.Traction makes to pull device return original after terminating in reverse order
Traction starting point, completes next traction preparation.Generally the erection of cat road track cable, is led using the reciprocating synchronization of single line mostly
Draw system to be constructed.
2nd, Double line reciprocating type synchronous traction system control flow：Double line reciprocating type sync pulling construction technology is using positioned at outstanding
Two hoist engines one of the same anchorage of cable bridge are received, one be rivals in a contest drawing haulage cable realize.The reciprocal trailer system of two-wire is covered often by three
Root haulage cable is constituted, and before starting traction, two hoist engines is first arranged on the homonymy of same anchorage, and wherein 1# hoist engines contain
The 1# haulage cables not pulled out, the 2# haulage cables in 2# hoist engines are drawn out, and one end fag end is connected with 2# hoist engines
Connect, other end fag end is on the opposite bank at anchorage；Opposite bank anchorage homonymy arranges horizontal guide sheave and Fang Suo mechanisms；Set up the 3rd 3# to lead
Draw steel wire rope, its two ends fag end is respectively placed at the anchorage of two sides；Device is pulled respectively in two sides anchorage appropriate location using two
Three haulage cables are coupled together, wherein 1# pulls device in hoist engine bank by 1# haulage cables and 3# haulage cables
Connection, 2# are pulled device and are connected 2# haulage cables with the 3# haulage cables for bypassing horizontal guide sheave on the opposite bank, form two-wire
Reciprocating-type tractor system.Double line reciprocating type trailer system workflow is as follows：Installed in putting, rope is in-house to be set up cat by traction
Road track cable（Or main push-towing rope）The device that pulls before front end anchor head, with horizontal guide sheave is connected temporarily, while starting two tractions
Hoist engine（One rope closing, another Synchronous Radio rope）→ low speed is across dissipating cable saddle door frame guide wheel group → sync plus white to allowing traction
Speed, goes upward at the top of king-tower preamble deceleration → low speed by door frame guide wheel group → sync plus white at the top of king-tower to allowing traction
Speeds cross main span, is close to opposite king-tower front reduction gear → low speed by door frame guide wheel group → sync plus white at the top of the king-tower of opposite to permitting
Perhaps hauling speed, comes downwards to opposite and dissipates cable saddle front reduction gear → low speed by dissipating cable saddle door frame guide wheel group → stopping traction, will be led
Draw and led cat road track cable in place（Or main push-towing rope）Front end anchor head is anchored with the connection of corresponding anchor system, completes single hitch frame
If.At the same time, before original is arranged on pulling at rack winch anchorage device is placed to opposite bank horizontal guide sheave, with next quilt
The cat road track cable that traction sets up（Or main push-towing rope）Front end anchor head is connected temporarily, while start two hoist engines, with identical
Flow process and contrary direction of rotation traction next Gen Mao roads track cable（Or main push-towing rope）, form Double line reciprocating type circulation and set up.Two-wire
Reciprocating synchronous traction system construction configuration is than the reciprocating sync pulling complicated construction technique of single line, but this efficiency of construction is compared with single line
Reciprocating sync pulling is doubled, and energy consumption also reduces nearly half.The erection of main push-towing rope is larger because drawing quantity, generally adopts
Double line reciprocating type synchronous traction system is constructed.
In both trailer systems, the synchronization of two hoist engines must all pass through this Project-developing " hoist engine is integrated
Control system " realizing, in whole distraction procedure, it is to be ensured that two to drawing hoist engine in distraction procedure energy synchronous averaging, and
On the basis of a hoist engine, the synchronized folding and unfolding of another hoist engine of control.In order to ensure the peace of equipment and personnel in running
Entirely, the dynamic detection of cable tension and the dynamic adjustment to passive elevator motor speed during system is by running to haulage cable,
Ensure the tension force of the steel wire rope in whole distraction procedure in the safe range for allowing；Cable system ought particularly be put and led
Yin Mao roads rope（Main cable strand）When there is Carcel, trailer system emergent stopping can be controlled in time, safety occurs in prevention system
Accident.Meanwhile, in distraction procedure, by spiral encoder and computer, by the positional information calculation for pulling device operation out,
Computer according to hauling speed-position data set in advance, will control the hauling speed of two rack winches, it is ensured that whole
In individual distraction procedure, particular across at the top of king-tower during door frame guide wheel group system operation safety.
