Abstract

The invention discloses a balance beam for lifting a platform truss and a lifting method thereof. The balance beam comprises a main beam (1), an operation platform (2) and a counterbalanced carriage (3), wherein the operation platform (2) is arranged above the main beam (1); the counterbalanced carriage (3) is hung on the main beam (1); and lifting lug plates (4) are arranged on the main beam. The platform truss can be lifted at one side; and the platform truss is adjusted to a horizontal state by using the main beam and a counterweight, and then is lifted. In the lifting, the platform truss is not blocked by a tower component blocking object, and can be directly mounted at the part, needed to be mounted, of a tower without needing operators to perform suspended operation, so that the safety of working at heights is improved, and the mounting efficiency is enhanced; the lifting method is safe and efficient; meanwhile, for components originally mounted from bottom to top in sequence, upper components can be mounted firstly when a perfecting scheme is not made for lower attachments or measures; and then the lifting of lower blocked components is performed by using the lifting method, so that the construction period is shortened, and the efficiency is improved.

Description

The equalizing bar of hoisting platform truss and hanging method thereof
Technical field
The present invention relates to a kind of building operation equalizing bar, especially the equalizing bar of hoisting platform truss.
Background technology
In television mast construction, after turret structure (more than 100 meters superaltitude) installs, need to decorations platform be installed to high building member shelter downside, as shown in Figure 1, original installation method need to be at side mounting jack under shelter, or leading sheave utilizes winch to change the method that hanging device carries out relay lifting, its tower crane suspension centre position namely stress point of platform truss 9 is positioned at the middle part of platform truss 9, crane hook 7 sling platform truss 9 to high building near time, because making the front end of platform truss 9 and position that high building need to be installed, the obstruction of high building member shelter produces certain distance, cause platform truss 9 directly not install, also need manually with chain block 8, platform truss 9 to be furthered, and the unsettled operation of fitting operation personnel, high-altitude safe has a big risk, and installation effectiveness is lower because need too many levels to coordinate.
Summary of the invention
The technical problem to be solved in the present invention be in prior art when television mast high building member shelter downside is installed to decorations platform, when tower crane sling platform truss middle part to high building near time, because making the front end of platform truss and position that high building need to be installed, the obstruction of high building member shelter produces certain distance, cause platform truss directly not install, also need manually with chain block, platform truss to be furthered, and the unsettled operation of fitting operation personnel, high-altitude safe has a big risk, and installation effectiveness is lower because need too many levels to coordinate.
For solving the problems of the technologies described above, the present invention adopts technical scheme as follows:
The equalizing bar of hoisting platform truss of the present invention, comprises girder, service platform and counter-balanced carriage; Described service platform is arranged on girder top, and counter-balanced carriage is hung on girder; On girder, be provided with lifting otic placode.On girder and the counter-balanced carriage platform truss that together colligation lifts at needs.Two lifting ropes are arranged on lifting otic placode, the balance weight of counter-balanced carriage calculates configuration according to the lifting eccentric moment of lifting components platform truss and equilibrium arm, and can according to platform truss vary in weight regulate, when keeping lifting components and equalizing bar, additional weight hoisting in horizontality.
As preferred version of the present invention, lifting otic placode is arranged on girder and between service platform and counter-balanced carriage.Suspension hook is sling by being arranged on the platform truss of the lifting rope needs lifting on equalizing bar by equalizing bar and colligation on lifting otic placode.
As preferred version of the present invention, lifting otic placode number has four, is evenly distributed on the girder between service platform and counter-balanced carriage, in counter-balanced carriage one side, be provided with ears plate, the ears plate of counter-balanced carriage one side fastens and fixes by bearing pin with the lifting otic placode that is positioned at girder end, and counter-balanced carriage is hung on to girder end.By the ears plate of counter-balanced carriage and the lifting otic placode that is positioned at girder end are fastened and fix this structure by bearing pin, to counter-balanced carriage is fixed on girder, prevents from getting loose and drop.
As preferred version of the present invention, lifting otic placode number has three, is evenly distributed on the girder between service platform and counter-balanced carriage, on counter-balanced carriage, be provided with slot with the contact component of girder, counter-balanced carriage one side is provided with ears plate, counter-balanced carriage is hung on girder afterbody by slot, the ears plate of counter-balanced carriage one side fastens and fixes by bearing pin with the lifting otic placode that is positioned at girder end, to counter-balanced carriage is inserted and is hung on girder end.。Counter-balanced carriage hangs on girder by slot, by the ears plate of counter-balanced carriage and the lifting otic placode that is positioned at girder end are fastened and fix this structure by bearing pin, has further improved the stability of counter-balanced carriage on girder again, prevents from that counter-balanced carriage from getting loose to drop.
As preferred version of the present invention, girder is pipe girder or square tube girder.
As preferred version of the present invention, service platform is board-like platform, is positioned at girder front upper, in service platform surrounding, is provided with fence.As upper air installing operating personal dismounting equalizing bar and the operation of truss tie string, use.
The equalizing bar of hoisting platform truss of the present invention, hanging method is as follows:
A, counter-balanced carriage is hung on girder, and with bearing pin, the lifting otic placode of the ears plate on counter-balanced carriage and girder end is fixed togather;
B, by girder and counter-balanced carriage together colligation in the outboard end of the platform truss of needs lifting;
Lifting rope is installed on c, the lifting otic placode on girder;
D, assisted suspension cable is installed on counter-balanced carriage, assisted suspension cable and lifting rope are together hung on crane hook, lift;
After e, lifting finish, lifting rope and the assisted suspension cable of dismounting girder and counter-balanced carriage and platform truss.
As preferred version of the present invention, the balance weight of counter-balanced carriage is to calculate configuration according to the lifting eccentric moment of platform truss and girder.Counter-balanced carriage can regulate according to the rear amount difference of platform truss, to keep equalizing bar when lifting of platform truss and hoisting platform truss in horizontality.
As preferred version of the present invention, the length of assisted suspension cable is 1.25 times of lifting rope lengths.
In sum, the advantage of the equalizing bar of hoisting platform truss of the present invention is can one-sided hoisting platform truss, utilizes girder and counterweight that platform truss is adjusted to horizontality, and recycling tower crane lifts.And during lifting, platform truss can not be subject to the obstruction of high building member shelter, can directly be installed to the position that high building need to be installed, and does not need the unsettled operation of fitting operation personnel, has improved the safety of aloft work, and has improved installation effectiveness.Adopt this hanging method safety, efficient, and can the member that order is installed from low to high will be pressed originally, when attached or measure row is worked out perfect scheme in bottom, upper component can be first installed, recycling this method is carried out the bottom lifting component that is blocked, and the reduction of erection time raises the efficiency.
