Description
Technical field
This utility model relates to a kind of derrick crane underframe being arranged on furnace roof, it particularly relates to one is supported on
Common building derrick crane bottom support basis above power plant boiler room steel construction, i.e. furnace roof derrick crane is removable
Undercarriage structure.
Background technology
Early construction, generally a common building tower with a ultra-large type self-raising tower crane are being installed by thermal power plant
Formula crane carries out Steel Structure Installation, and such two tower crane amplitudes just can cover whole boiler room；And arrived power plant boiler
Room build later stage, i.e. the main girder steel (large girder) of boiler room install in place after, now, the tower lifting of building having reached common
The lifting altitude limit of machine, in order to work normally, at this moment or with a crawler crane coordinates lifting, or installs one again
Platform ultra-large type self-raising tower crane, but the cost of both approaches is the highest, and the input of equipment is the biggest, and at fire
In the later stage that Boiler House is built, the weight of the one piece apparatus of required lifting is all little, and the somewhat the biggest material of both schemes is little
With.
In this case, if it is possible to the building tower crane that a Daepori is logical is installed at the top of main girder steel, can
Meeting job requirement, cost is the highest；And the component that bigger load can be born in top, boiler room has main girder steel and four steel
Beam, four times girder steel is distributed in main girder steel both sides two-by-two, and upper table and the main girder steel upper surface of secondary girder steel have certain difference in height, as
Shown in Fig. 1, main girder steel and time girder steel broadly fall into the internal main stress component of power plant, do not allow external component to weld with it；And it is tower
Crane is when normally working, and tower crane underframe part stress is complicated, i.e. wants to bear the pressure of alternation, also wants to bear alternation
Pulling force.So according to the distinctive operating mode in boiler top, developing one and both need not be welded on main girder steel and time girder steel, the most just
In the furnace roof derrick crane Undercarriage structure of dismounting, there is the biggest practical value and economic worth.
Summary of the invention
The purpose of this utility model provides one to install for the special structure in power plant boiler roof portion just
It is being positioned at main girder steel and the tower lifting of dismountable common building at two, left and right longitudinal direction time girder steel top at top, boiler room
Machine Undercarriage structure.
The purpose of this utility model can be realized by following technique measures:
The removable Undercarriage structure of furnace roof derrick crane of the present utility model includes the main girder steel being positioned at top, boiler room, with
Two, the left and right longitudinal direction that the parallel mode traversing main girder steel facade is arranged on main girder steel time girder steel；Before being positioned at main girder steel facade
In the way of parallel with main girder steel, a support leg beam it is separately installed with on two, the left and right at rear longitudinal direction time girder steel；At two supporting legs
On beam, in the way of riding main girder steel, parallel left and right two foundation that are provided with are set a roof beam in place；Described undercarriage bea top flange plate and tower body main chord
Connect.
Supporting leg depth of beam described in this utility model is equal to the difference in height of main girder steel upper surface with time girder steel upper surface, long
Degree is more than or equal to the distance between two, left and right longitudinal direction time girder steel outer side edges.
This utility model is respectively and fixedly connected with lower end at described support leg beam two ends and is provided with the box-shaped supporting leg of mounting flange, if
Put the box-shaped supporting leg at support leg beam two ends by connecting bolt and backing plate girder steel Joint secondary with two, left and right longitudinal direction respectively；Described
Supporting leg depth of beam is adjusted by connecting bolt and backing plate according to the difference in height of main girder steel and time girder steel.
Support leg beam described in this utility model is I-shaped cross-section, is just being provided with undercarriage bea connecting portion even at support leg beam
Acting flange, is connected by bolt and undercarriage bea, is being provided with reinforcement with corresponding position, adpting flange position；Described undercarriage bea is
Box section, is just welded with cross gusset, undercarriage bea lower flange at link position to tower body main chord inside undercarriage bea
Plate two ends are welded with box-shaped flange seat, for being connected with support leg beam；Undercarriage bea length is more than tower body sectional dimension.
Operation principle of the present utility model is as follows:
When tower crane tower body main chord bears pressure, the pressure of main chord directly passes to main girder steel by undercarriage bea
And support leg beam, that a part of pressure passing to support leg beam passes to time girder steel still further below；When tower crane tower body main chord bears
During pulling force, the pulling force of main chord passes to undercarriage bea, and pulling force is passed to support leg beam by flange bolt by undercarriage bea, and support leg beam is again
By backing plate and stay bolt, pulling force is passed to time girder steel again.Therefore this underframe can either meet tower crane main chord tension operating mode,
Also main chord pressurized operating mode can be met.
Useful benefit of the present utility model is as follows:
This utility model solves the problem that common building tower crane " is taken root " nowhere at top, boiler room, and this underframe is
Demountable structure, reusable；Meanwhile, crawler crane or ultra-large type are substituted from rising tower with a tower crane being arranged on furnace roof
Formula crane works, it is possible to saves substantial amounts of fund, greatly reduces the construction cost of power plant.
