Description
Technical field
The present invention relates to a kind of pipeline fixing device, and in particular to a kind of expansion of solution boiler connecting pipe and consolidating of being oriented to
Determine device.
Background technology
As shown in Figure 1 and Figure 2, it is the welding support on boiler post and beam to current boiler body connecting pipe hanging form,
Suspend spring support hanging frame in midair below support, spring support hanging frame connects four gussets in support beam, connecting tube by suspension rod and is supported on
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 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, and the change produced with boiler is indefinite, and 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 limits the length of suspension rod, also limit heated
The length in face.
The content of the invention
The present invention is difficult type selecting to solve the spring hanger of existing boiler connecting pipe fixing device, easy restriction conduit from
It is easy to failure stuck after expanded by heating by expanding, install inconvenient, space-consuming is big, cost is high and support beam assembles, changes tired
Difficult the problem of, and then a kind of fixing device for solving the expansion of boiler connecting pipe and being oriented to is provided.
The present invention is for the technical scheme that is proposed of solution above-mentioned technical problem：One kind solve the expansion of boiler connecting pipe and
The fixing device of guiding includes suspension rod, bearing rib and support beam, and suspension rod upper end and support are detachably connected, lower end and support beam
It is detachably connected, bearing rib is fixed on connecting pipe and positioned at support beam top, and connecting pipe passes through the center of support beam,
Gap is provided with support beam, bearing rib is stuck on gap and can drive support beam horizontal movement.
The beneficial effects of the invention are as follows：Present invention eliminates spring hanger, cost is reduced, space is saved；Support beam skid beam
On be provided with gap, interface channel is not rocked, play guide and limit effect, save guider cost, further reduce into
This；Support beam is detachably assembled by bolt, convenient positioning and assembling, is changed convenient, only bolt and nut need to be changed, compared to original
Need cutting support beam safer；When pipeline expands downwards, support beam is promoted to be moved forward and backward in mounting hole length range, kidney-shaped
Hole length can be equipped with displacement, effectively eliminate the influence of thermal expansion；Thermal stress is not limited, all by support beam and suspension rod
Absorb, reduce weld pressure, and meet load.
