Embodiment 4
The detailed process of the method for the present invention is provided below, flow chart is as shown in figure 14.
One, process
1, one suspender of gantry crane is changed to rotary type suspender.
2, beam gun carriage pose adjustment is transported
1) fortune beam gun carriage specifies the installation region Yun Liang close to precasting yard, and smooth compacting is answered in place.Pay special attention to gate-type lifting
The unimpeded of the access way for guaranteeing fortune beam gun carriage is had in the position of machine.
2) angles and positions of beam gun carriage front truck, rear car are transported in adjustment, guarantee vehicle body and track oblique, drive into specified fortune Liang An
Region is filled, is parked in gantry crane across interior.
3) the fortune beam bracket for transporting beam gun carriage rear car is adjusted to be adjusted to and vehicle body with parallel track direction, front truck fortune beam bracket
Vertical direction.
3, gantry crane bale handle moves forward
1) vehicle and irrelevant personnel for evacuating bale handle area complete the inspection of Operational Zone track, cleaning sundries.Preparation is in place
Afterwards, each care provider has drawn warning line, staff under evacuation machine.It checks each position situation of equipment, is opened after having service condition
Beginning operation.
2) from beam making bench bale handle: gantry crane mule carriage in place, to good sunpender, falls suspender, tying up bar fills nut.It hangs
Bar contraposition will just, conducive to penetrating, and beam body is shaken when also can avoid demoulding.Will uniformly with beam body gap when nut is installed, sunpender dew
Screw thread is consistent out, adjusts 4 groups of sunpender uniform stresseds.
3) fine motion divides end gradually lifting trolley suspension centre, until beam body stops when being detached from 3cm with die body, checks whether braking is clever
It is quick, reliable, while it is connectionless to check that beam body and die body have, and starts raising after verifying demoulding completely.Gradually accelerate, promotion exceeds fortune
Line direction area barrier 0.5m or more.
4) bale handle in place before, pre-decelerating, low speed contraposition avoids beam body large-amplitude sloshing, and confirmation beam body is stable, position is quasi-
After really, it can command and fall beam.Pre-decelerating before falling beam in place, low speed is close and aligns.
4, gantry crane fixed spreader end falls beam
1) Luo Liangqian puts hardwood or rubber support pad well in advance between beam body and car body bracket, and position is accurate, protects beam
Piece and anti-sliding stop.
2) precast beam promotion is transported to the specified installation region Yun Liang and stops, and slowly declines beam body to the fortune for transporting beam gun carriage rear car
On beam bracket, each fulcrum wants accurate contraposition.Using the support of dedicated steel construction fixed frame or binding wirerope being fixed on car body
And beam body is connect tightening with fortune beam gun carriage by chain block, to ensure that precast beam and beam car have balance, stable reinforcing.
3) the upright bar screw for dismantling hanging beam special implement, slowly promotes hanging beam utensil, is detached from beam body and gantry crane.Sunpender
After nut disassembly, after confirmation is without card resistance when hooking up, raising suspender to safe bridge height.
5, gantry crane continues Forward, rotary type suspender end falls beam
1) gantry crane continues bale handle Forward, and the fortune beam bracket for transporting beam gun carriage rear car in the process is synchronous with Rotatable sling
Rotation, trolley, which synchronizes, to come closer, until stopping advancing when beam body is consistent with fortune beam gun carriage direction.
2) slowly in decline beam body to the fortune beam bracket of fortune beam gun carriage front truck, each fulcrum wants accurate contraposition.Using being fixed on
Beam body is connect tightening with fortune beam gun carriage by the support of dedicated steel construction fixed frame or binding wirerope and chain block on car body, with
Ensure that precast beam and beam car have balance, stable reinforcing.
3) the upright bar screw for dismantling hanging beam special implement, slowly promotes hanging beam utensil, is detached from beam body and gantry crane.Sunpender
After nut disassembly, after confirmation is without card resistance when hooking up, raising suspender to safe bridge height.
6, dress beam is completed, and gantry crane sails out of the installation region Yun Liang, fortune beam gun carriage starting fortune beam.
Two, equipment requirement
Gantry crane: Ying Peibei two-electron atom (trolley), and have the ability for singly slinging weight precast beam.
Fortune beam gun carriage: it is divided into front truck and rear car.Respectively by bodywork assembly, bogie assembly, brake apparatus, driving device,
Support and fix device (fixed frame or diagonal brace) composition.
Rotary type suspender: one suspender of gantry crane is changed to rotary type suspender, has 360 degree of rotations after transformation
Rotating function, the speed of rotation are slowly controllable.
Three, points for attention
1) gantry crane workplace away from
It at work, should there are certain space rulers between gantry crane external dimensions and precast beam and fortune beam gun carriage
It is very little, in favor of handling operation.When general fortune beam gun carriage loads and unloads in span, the spacing for having 0.7m or more with door leg should be kept, is hung
Has the spacing that the Ying Yuyun beam gun carriage when not working has 0.5m or more.
2) bale handle Forward should be slow, synchronous
It transports the fortune beam bracket of beam gun carriage rear car and precast beam is carried out after fixing, gantry crane should slowly move forward, and should ensure that
The slow rotation synchronous with the fortune beam bracket of rear car of rotary type suspender, trolley, which synchronizes, to come closer, and operational process is not obstructed,
It avoids precast beam that internal force occurs to destroy.
3) routine inspection before large scale equipment operation
Precast beam is before the operations such as lifting, entrucking, it is necessary to first check the equipment used, and if it is in shape, it is not inconsistent
Closing job requirements should be overhauled in time.As gantry crane is every lifted a hole beam piece after should conscientiously check wirerope, suspender
The key positions such as sunpender, hoist engine and braked wheel brake；Tire type beam conveying vehicle is before use, should conscientiously check tire pressure, draw
Hold up cistern water level, the flexibility of steering wheel rotation, sensitivity, the integrality of direction adjustment device of brake apparatus etc..
The above embodiment make single-door crane of the present invention across interior oblique angles fall beam construction technology have it is versatile,
Have a wide range of application, the advantages that process flow is simple.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
