In order to meet the need of work of tower crane, the structure of tower crane rood beam is except that can bear lifting power and hoisting moment
Outward, it is necessary to bear the whole tower crane whole load of itself.
The rood beam of usual middle or small tonnage tower crane is adopted the structure to undertake, transmit the whole of tower crane, it is ensured that tower crane is pacified
Entirely, efficiently work.Design when must take into consideration stress transition and transmission etc., while it is also contemplated that transport the need for, generally
Rood beam is designed as a limb is overall, another limb two halves, as shown in Figure 1, Figure 2 and Figure 3.
When in working order, linked into an integrated entity by bearing pin；, it is necessary to one of rood beam is entered during tower crane is transported
Row is disassembled.Be correct, the convenient installation for ensureing rood beam, while in the design of rood beam, should combine installation convenience,
It is quick to consider.
On the larger derrick crane of lifting tonnage, rood beam bears larger load when working.Now, tower machine upper
The load for passing over is relatively large.So, cross girder construction must more could be firmly the work that stabilization is provided in dynamic tower crane
Ensure；Otherwise, there will be the potential safety hazard of possibility whole machine unstability when tower crane works.
And in large-scale, ultra-large type tower crane, rood beam in addition to needing to meet above-mentioned requirements, the transport of rood beam, just
Position, adjustment are also the important performance that can not be ignored.
The content of the invention
For the problem that above-mentioned prior art is present, the utility model provides a kind of collapsible rood beam knot of derrick crane
Structure, in the case of ensureing enough bearing capacity, transfer can be realized when the convenience transported.
To achieve these goals, the technical solution adopted in the utility model is：A kind of collapsible cross of derrick crane
Girder construction, it includes：
Two are mutually intersected in beam of the carrier block in decussate texture；

Expansion forms bi-lug plate, and connecting hole is provided with each otic placode, is equally again provided with otic placode, connecting hole in the inner end of exopodite beam；
In a state of use, exopodite beam, interior limb beam form a unjointed beam by dual link hole；
In a non-operative state, exopodite beam, interior limb beam form collapsible beam by single connection hole.
Described connecting hole is pin shaft hole or bolt hole.
Described exopodite beam end is hydraulically extensible oil cylinder.
Described otic placode is circular otic placode.
Rood beam of the present utility model is folding beam, it is made up of both exopodite beam, interior limb beam；On the side of interior limb beam
Edge two ends are expanded to form bi-lug plate, and connecting hole is provided with each otic placode, are equally again provided with otic placode, company in the inner end of exopodite beam
Connect hole；In a state of use, exopodite beam, interior limb beam form a unjointed beam by dual link hole；In a non-operative state, exopodite
Beam, interior limb beam form collapsible beam by single connection hole, to lifted tower crane rood beam bearing capacity, facilitate building site to shift when
Transport, with effective important function；
It is the reduction of the cost of the utility model processing and manufacturing simultaneously, easy to maintenance and rational in infrastructure, safe and reliable, convenient real
With.
