Description
Technical field
The utility model relates to the air feeder structures that technical field of bridge engineering more particularly to a kind of dry air dehumidify.
Background technique
Cable-stayed bridge is the modern carrying of large span cable one of bridge structure design and the important form of application, and drag-line is this
The core component of structure, load-bearing, transmitting load-carrying ability are the key that bridge security operations.Master of the high-tensile steel wires as drag-line
Body often leads to the performance degradation of cable until failure in military service load bearing process due to corrosion.Dry air dehumidifying technology is logical
Main push-towing rope steel wire can be effectively prevent for the main push-towing rope of dry air input suspension bridge with the humidity reduced in main push-towing rope by crossing Roots blower
Corrosion, has been used successfully to the humid control of more main rope of suspension bridge, and have become the important anti-corrosion method of main rope of suspension bridge, but
The dry air dehumidifying technology application of cable-stayed bridge cable is not yet found at present.
For the dry air dehumidifying technology of drag-line, Authorization Notice No. CN103174092A(Patent No.:
ZL201310072105.3 utility model patent) discloses a kind of stayed structure and its implementation that can be filled with dry air,
Air inlet and outlet stainless-steel pipe is respectively set in stayed structure upper and lower ends in it, and dry air can be inputted by steel pipe in cable body
Portion dehumidifies, but when inputting dry air by air inlet pipe, due to originals such as the friction losses of cable body bulk and gas
It is sharply lost because causing to enter the intracorporal gas pressure intensity of rope, especially length is longer, the biggish drag-line of specification.In general, Cable
Internal humidity is top is small, lower part is big, and gas pressure intensity loss very greatly, is unfavorable for rope when dry air reaches cable body lower part
The exclusion of internal humidity, this causes drag-line dehumidification efficiency and effect low.Therefore, a kind of raising drag-line dry air dehumidifying effect is needed
The structure or method of fruit.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of air feeder structures of dry air dehumidifying, can mention
High cable body dehumidification efficiency and reduction intake air pressure, it is energy saving.
Purpose of the utility model is realized as follows:
A kind of air feeder structure of dry air dehumidifying, it includes air inlet tube body, and the air inlet pipe fills anchor face in upper anchorage
Several gas outlets are set, and the gas outlet diameter is less than air inlet bore, and the length of the air inlet pipe is more than cable body length
Half.
A kind of air feeder structure of dry air dehumidifying, the gas outlet quantity is 2 ~ 8.
A kind of air feeder structure of dry air dehumidifying, the gas outlet diameter is 0.1 ~ 0.5 times of air inlet bore.
A kind of air feeder structure of dry air dehumidifying, the air inlet pipe end is air outlet, and air outlet distance is casted anchor
Tool fills anchor identity distance from for 0.001m ~ 3m.
Compared with prior art, the utility model has the beneficial effects that
Air inlet pipe is substituted cable body steel wire by the utility model, and anchorage fills setting gas outlet at anchor face in air inlet pipe, together
When air inlet pipe air outlet extended close under cable body anchorage fill at anchor face, on the one hand due to air inlet pipe extend dry air is straight
It connects to be sent to close to lower anchorage and fill at anchor face, on the other hand air inlet pipe setting gas outlet can remove rope at the filling anchor face of upper anchorage
The humidity on body top, and eliminate air inlet pipe air outlet and fill the turbulent flow generated at anchor face in lower anchorage.With existing drag-line dry air
Dehumanization method is compared, and cable body dehumidification efficiency can be improved and reduce intake air pressure, and then is energy saving, the industry with height utilizes
Value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the air inlet pipe of the utility model dry air dehumidifying.
Fig. 2 is the utility model air inlet pipe, escape pipe in the intracorporal arrangement schematic diagram of rope.
Fig. 3 is that the utility model escape pipe is located at lower anchorage wire sub-panel schematic diagram.
Wherein:
Gas outlet 1, air inlet pipe 3, escape pipe 4, fills anchor face 5 at air outlet 2.
Specific embodiment
Referring to Fig. 1-3, the utility model relates to a kind of dehumidifying of dry air air feeder structure, it includes air inlet pipe 3
Body.
The air inlet pipe 3 is filled in upper anchorage is arranged gas outlet 1 at anchor face 5, and 3 air outlet 2 of air inlet pipe is close under cable body
Anchorage fills 5 position of anchor face, i.e. the top setting gas outlet 1 of air inlet pipe 3 is to dry Cable using 3 part dry air of air inlet pipe
Body top, and the dry air of 3 air outlet 2 of air inlet pipe then dries the part cable body close to lower anchorage position.
In said structure, cable body length is 11m, and specification is 109 × 5.Air inlet pipe 3 uses stainless steel tube, surface and rope
Body wire galvanization aluminum alloy coating is identical, and 3 outer diameter of air inlet pipe is 5mm, pipe thickness 0.5mm；Air inlet pipe gas outlet 1 away from
For less than 2m with a distance from upper anchorage, it is preferred that gas outlet is 0 ~ 1m apart from upper anchorage distance, such as this embodiment gas outlet distance
Upper anchorage distance is 10cm；Meanwhile 1 quantity of gas outlet is greater than 1, preferred gas outlet quantity is 2 ~ 8, outlet in this example
Mouth is 4；1 diameter of gas outlet is less than 3 internal diameter of air inlet pipe, it is preferred that 1 diameter of gas outlet is the 0.1 ~ 0.5 of 3 internal diameter of air inlet pipe
Times, it is 0.2 times of 3 internal diameter of air inlet pipe that 1 diameter of gas outlet, which is 1mm, in this example；2 position of air inlet pipe air outlet is greater than
The half of cable body length, it is preferred that under 2 positional distance of air inlet pipe air outlet anchorage fill anchor face 5 apart from be 0.001m ~ 3m,
Intake manifold length is 10m in example, i.e., fills anchor face 5 apart from for 1m apart from lower anchorage.Charge air conditioning uses nitrogen in cable body.
The above is only the specific application examples of the utility model, do not constitute any limit to the protection scope of the utility model
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
