On, girder and folded beam are lifted up by tower crane or electric block, when two hoisting wireropes are just tightened, make girder to
The right side moves horizontally, and girder left end is detached from reserved opening, is further continued for promoting girder and folded beam, folds until the height of promotion is greater than
Stop tower crane or electric block after the length of beam, then remove upper pin, folded beam is downward in door opening by shaft of lower bearing pin
Fold, folded beam is vertically arranged at this time, girder and folded beam in elevator, then start tower crane or electric block continue to
Upper promotion girder and folded beam,
Stop tower crane or electronic calabash after folded beam is corresponding with door opening on one or more layers upper elevator right side wall or so
Reed, girder is higher than one or more layers reserved opening on elevator left side wall at this time；Then folded beam is rotated to upper right, is folded
Beam is extend into door opening, supports that end plate is corresponding to be contacted until the first of the second support end plate and girder right end of folded beam left end
Afterwards, upper pin is plugged between two pieces of upper mobile boards and two pieces of upper mounted plates；
Restart tower crane or electric block, fall girder and folded beam, when the reserved opening on girder and elevator left side wall is high
Stop tower crane or electric block when spending consistent, girder and folded beam is moved horizontally to the left, girder left end extend into reserved opening
Interior stopping restarts tower crane or electric block, further falls girder and folded beam, makes girder left end bottom and folded beam right end
Bottom, which is respectively supported on the bottom plate of reserved opening and door opening, stops tower crane or electric block, removes two lifting wirerope, together
When using expansion bolt by folded beam right end be fixed to door opening bottom plate on；
Then it is tensioned traction rope, disassembly is previously used for the steel label and metal binding wire rope of temporary fixed weight, after items regulate,
Promotion operation is increased in completion.
By adopting the above technical scheme, the present invention is novel in design, easy to use, quick, easily operated, and this method is through reality
Test application, it is faster, more convenient, more energy efficient, more environmentally friendly than conventional installation method.It is that the present invention is whole without linear type fastly
Inclination hanging when body beam operation, without weight 80kg, the manpower of high 1500mm split heads pickaback, saves 5 repeatedlyφ
The sheave of 400mm diameter eliminates extra wirerope and passes around while reducing labor intensity；Conveniently it is that the method can be with
Segmentation folds, and balance lifting eliminates passing around for wirerope；Energy conservation is that the method can save 2/3 wirerope dosage, one
It is always that walk 6 ropes be exactly 1800m to 100m*3 with rope amount, the method can save 1200m rope using the building hoist of height 100m
Amount,φWire Rope theory weight 34.6kg*1200m=415kg of 10mm, saves 5φThe sheave of 400mm diameter, each
Sheave presses 25kg*5=125kg, and such building hoist integrally mitigates weight 540kg, and alleviating weight also just reduces work
Function reduces work done, and saving on the energy reduces discharge, has reached energy-saving and environment-friendly purpose.In short, the present invention provides one
Kind is simple, quick, at low cost, energy-saving and environmental protection efficient " a kind of folding day beam traction-type construction lifting machine " are also expanded simultaneously

Two lifting wirerope used in step (4) hang two balance lifting lugs in two the balances lifting lugs and right side in left side respectively
On, girder and folded beam are lifted up by tower crane or electric block, when two hoisting wireropes are just tightened, make girder to
The right side moves horizontally, and girder left end is detached from reserved opening, is further continued for promoting girder and folded beam, folds until the height of promotion is greater than
Stop tower crane or electric block after the length of beam, then remove upper pin, folded beam is downward in door opening by shaft of lower bearing pin
Fold, folded beam is vertically arranged at this time, girder and folded beam in elevator, then start tower crane or electric block continue to
Upper promotion girder and folded beam,
Stop tower crane or electronic calabash after folded beam is corresponding with door opening on one or more layers upper elevator right side wall or so
Reed, girder is higher than one or more layers reserved opening on elevator left side wall at this time；Then folded beam is rotated to upper right, is folded
Beam is extend into door opening, supports that end plate is corresponding to be contacted until the first of the second support end plate and girder right end of folded beam left end
Afterwards, upper pin is plugged between two pieces of upper mobile boards and two pieces of upper mounted plates；
Restart tower crane or electric block, fall girder and folded beam, when the reserved opening on girder and elevator left side wall is high
Stop tower crane or electric block when spending consistent, girder and folded beam is moved horizontally to the left, girder left end extend into reserved opening
Interior stopping restarts tower crane or electric block, further falls girder and folded beam, makes girder left end bottom and folded beam right end
Bottom, which is respectively supported on the bottom plate of reserved opening and door opening, stops tower crane or electric block, removes two lifting wirerope, together
When using expansion bolt by folded beam right end be fixed to door opening bottom plate on；
Then it is tensioned traction rope, disassembly is previously used for the steel label and metal binding wire rope of temporary fixed weight, after items regulate,
Promotion operation is increased in completion.
