Abstract
The invention discloses a kind of construction method transporting beam on heavy grade, include following operating procedure: 1) flat car for transport of sills dress beam fix box beam with zipper calabash, steel wire rope of windlass is linked with flat car for transport of sills traction and connects, startup hoist engine makes the slight stress of steel wire rope；2) flat car for transport of sills operator is in place, releasing of brake, starts flat car for transport of sills and hoist engine simultaneously, and flat car for transport of sills starts climbing, and operator adjust flatcar travel direction；3) after flat car for transport of sills sails out of top, slope, stop, remove haulage cable, flat car for transport of sills drive from dynamic offer.By improving the pull strength of flat car for transport of sills or imposing external force traction, in the case of great slope, flat car for transport of sills can normally work, and box beam is transported to installation site.
Description
Technical field
The present invention relates to box girder transport field, particularly belong to a kind of construction method transporting beam on heavy grade.
Background technology
Flat car for transport of sills is to set up custom-designed transporting precast beams machinery for highway bridge.By two operations independently
Mechanism's (actively car, by motor-car) composition.Main car arranges four cylinders or six-cylinder diesel engine and slows down as car load offer driving force through level Four.End
Level is driven to take turns limit gear wheel or Planetary Gear Transmission.Fluid-link steering is set and gas is stopped function.It is generally provided with multiple drive shift
And reverse drive gear.Secondary car sets single cylinder diesel provides power as fluid-link steering.Flat car for transport of sills has fortune beam concurrently and to Bridge Erector feeding beam
Function, is primarily adapted for use in bridge formation building site, precast beam field etc..Existing flat car for transport of sills longitudinal direction climbing capacity is less, typically requires the gradient
It is not more than 5%.Being restricted by field condition during practice of construction, longitudinal gradient is often difficult to meet flat car for transport of sills requirement, it is necessary to give
Improve.
Summary of the invention
It is an object of the invention to provide a kind of construction method transporting beam on heavy grade, by improving the traction of flat car for transport of sills
Power or impose external force traction, in the case of great slope, flat car for transport of sills can normally work, and box beam is transported to installation site.
Technical scheme is as follows:
A kind of construction method transporting beam on heavy grade, includes following operating procedure:
1) flat car for transport of sills fills beam and fixes box beam with zipper calabash, is linked with flat car for transport of sills traction by steel wire rope of windlass and connects, opens
Dynamic hoist engine makes the slight stress of steel wire rope；
2) flat car for transport of sills operator is in place, releasing of brake, starts flat car for transport of sills and hoist engine simultaneously, and flat car for transport of sills starts climbing,
Operator adjust flatcar travel direction；
3) after flat car for transport of sills sails out of top, slope, stop, remove haulage cable, flat car for transport of sills drive from dynamic offer.
Flat car for transport of sills climbing capacity of the present invention is limited by power configuration, when actual grade is more than the specified gradient, it is necessary to provide
Extra pull strength, it is ensured that flatcar can normally travel.Employing hoist engine draws, and technology maturation puts into little, it is easy to operation, safety
Highly reliable.One-level lock 88 small box girder in Nanling use the method to transport, and work progress all goes well, and any safe matter does not occurs
Amount accident, it is ensured that what precast beam was installed is smoothed out.
Accompanying drawing explanation
Fig. 1 is the fortune beam schematic diagram of the present invention.
Beam body stress exploded view when Fig. 2 is for going up a slope.
Detailed description of the invention
See accompanying drawing, a kind of construction method transporting beam on heavy grade, include following operating procedure:
1) flat car for transport of sills 1 fills beam and fixes box beam with zipper calabash, is linked with flat car for transport of sills 1 traction by steel wire rope of windlass 2 and connects,
Start hoist engine 3 and make the slight stress of steel wire rope 2；
2) flat car for transport of sills 1 operator is in place, releasing of brake, starts flat car for transport of sills 1 and hoist engine 3 simultaneously, and flat car for transport of sills 1 starts to climb
Slope, operator adjust flatcar travel direction；
3) after flat car for transport of sills 1 sails out of top, slope 4, stop, remove haulage cable 2, flat car for transport of sills 1 drive from dynamic offer.
G beam and beam car gross weight in Fig. 2, G=80(beam weight)+12.5(beam car weight)=92.5(t)
G1 is perpendicular to domatic component
F is parallel to domatic component, i.e. needs pull strength F=92.5*8.5/100.4=7.83 (t) provided
Flat car for transport of sills self climbing is considered by 4% gradient, then its pull strength F1 provided is calculated as follows:
F1=92.5*4/100.1=3.70(t)
Pull strength F2=7.83-3.7=4.13 (t) provided by hoist engine
Use 5T hoist engine, its pull strength maximum 5T provided, flat car for transport of sills climbing power demand can be met.
