Background technology
As shown in Figure 1 and Figure 2, it is the welding support on boiler post and beam to the form of boiler body connecting pipe hanging at present,
Suspend spring support hanging frame in midair below support, spring support hanging frame connects support beam by suspension rod, and four gussets are supported in connecting tube
In support beam, because the medium in pipeline is high-temperature steam, corresponding displacement and thermal stress are had relative to fixing point, so adopting
With spring hanger, support beam and suspension rod pull the spring in spring hanger to absorb the swell increment of jet chimney, although this structure
Can extraction duct swell increment, but error can be produced when selecting spring hanger according to displacement and load, i.e. (work load-installation
Load)/work load≤25%, and when load it is too small, suitable spring hanger, spring hanger can not be selected when displacement is excessive
Also need to consider to conduct oneself with dignity, so spring hanger type selecting is cumbersome and more difficult, high-temperature medium is to material strips during boiler operatiopn
The thermal stress come is indefinite, is indefinite with change caused by boiler, spring hanger by displacement and load due to being influenceed, very
The free wxpansion of easy restriction conduit so that difficulty is brought during boiler operatiopn, because spring hanger profile is larger with respect to suspension rod, peace
Inconvenience is loaded, is limited by appearance and size, this structure very space-consuming, the length of suspension rod is limited, also limit heated
The length in face.
Utility model content
The utility model is not easy type selecting, easy restriction conduit to solve the spring hanger of existing boiler connecting pipe fixing device
Free wxpansion, easy to failure stuck after expanded by heating, installation is inconvenient, and space-consuming is big, and cost is high and support beam assembling, more
The problem of changing difficulty, and then a kind of fixing device for solving the expansion of boiler connecting pipe and being oriented to is provided.
The utility model is to solve the technical scheme that is proposed of above-mentioned technical problem：It is swollen that one kind solves boiler connecting pipe
Fixing device that is swollen and being oriented to includes suspension rod, bearing rib and support beam, and suspension rod upper end and support are detachably connected, lower end and branch
Support beam is detachably connected, and bearing rib is fixed on connecting pipe and is located at support beam top, and connecting pipe passes through support beam
Center, gap is provided with support beam, bearing rib is stuck on gap and can drive support beam horizontal movement.
The beneficial effects of the utility model are：The utility model eliminates spring hanger, reduces cost, saves space；Branch
Gap is provided with support beam skid beam, interface channel is not rocked, guide and limit effect is played, saves guider cost, enter one
Step reduces cost；Support beam is detachably assembled by bolt, and convenient positioning and assembling, it is convenient to change, and only need to change bolt and nut,
Need cutting support beam safer compared to original；When pipeline expands downwards, promote support beam front and rear in mounting hole length range
Mobile, kidney-shaped hole length can be equipped with displacement, effectively eliminate the influence of thermal expansion；Unlimited heating stress, all by propping up
Support beam and suspension rod absorbs, reduce weld pressure, and meet load.
