Description
Technical field
The present invention relates to a kind of curing system, especially relate to the curing system of a kind of high ferro precast bridge.
Background technology
Why high ferro precast bridge prefabricated employing C50 high performance concrete, after concreting, can gradually condense hard
Change, be primarily due to the result of concrete hydrating effect.Hydration then needs suitable temperature and humidity condition, therefore
In order to ensure that concrete has suitable curing condition so that it is intensity constantly strengthens, it is necessary to carry out concrete spraying maintenance.Mixed
After solidifying soil cast, as hot climate, air are dried, carrying out not in time spraying maintenance, in concrete, moisture can evaporate too fast, shape
Becoming dehydrating phenomena, the cement granules that can make to have been formed gelinite can not abundant aquation, it is impossible to is converted into stable crystallization, lacks enough
Enough cohesive forces, thus can occur that lamellar or powdery come off at concrete surface.Additionally, not yet possess enough at concrete
During intensity, the too early evaporation of moisture also can produce bigger contraction distortion, cup shake occurs, affect concrete durability and
Globality.So the maintenance of initial stage is extremely important after concreting, maintenance after concrete final set, should be carried out immediately.
At present, the fixing device used in the curing means of high ferro precast bridge, nozzle is immovable, sprays region solid
Fixed.All spraying region to cover, the quantity arranging nozzle is many；Must there is cross-operation in each nozzles spray region, right
The consumption of water is big, wastes resource；Existing and spray dead angle, spray maintenance effect is the best.Although using manual method maintenance to solve
The problem certainly spraying dead angle, but needs to climb up to climb down, and the height of precast bridge is liftoff typically at 4-5 rice, extremely dangerous, time-consuming takes
Power, inefficient, cost is greatly increased.
Chinese patent notification number 204450828 U application number 201520108524.2 discloses a kind of high ferro precast bridge
Curing system, as it is shown in figure 1, spray equipment in including in the case to sections bridge the case of spray, for sections bridge
The case outer left side spray equipment that the outer left side of the case of beam sprays and the case external right side for spraying the case external right side of sections bridge spray
Shower device, described case outer left side spray equipment and case external right side spray equipment be symmetrical arranged, described case outer left side spray equipment and
The structure of case external right side spray equipment identical and all include the outer shower of walking mechanism, case and for the outer shower of driving box along
The outer shower driving means of the case that walking mechanism top is slided, the outer shower of described case is arranged on the top of walking mechanism, described
Being provided with the outer spray head of multiple case on the outer shower of case, the outer shower of described case drives and is arranged in walking mechanism.Although solving
The problem of mobile spray, but water source is fixed, relies on the water source of flexible pipe and maintenance water to connect, certainly will cannot meet distance many
The maintenance of Duan Qiaoliang, its operating distance is limited by the length of flexible pipe；The maintenance of the inner space of precast bridge and the maintenance of flank
Temperature and humidity requires difference, and flank is thin to be opened wide exposed many completely, needs many frequencys moistening and lowering temperature, inner space then almost without
Needing humidification, this patent but cannot be distinguished from treating；The upper surface of bridge cannot be carried out moistening and lowering temperature maintenance, and upper surface directly connects
By insolation, it is especially desirable to maintenance；Additionally there are the problems such as structure is loaded down with trivial details, fault rate is high, intelligence degree is low.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency of the prior art, it is provided that the two-sided spray of a kind of high ferro precast bridge

Time, enabling signal passed to switch board 8 by sensor, and switch board controls power-driven system 6 and starts working, according to predetermined track
Stop after covering whole impulse stroke, it is achieved fully-automatic sprinkling maintenance work.
Described walking mechanism arranges warning lamp 10 and blows a whistle, and warning crosses the staff of track and takes care.
In order to lift by crane conveniently, the sectional portraitlandscape of precast bridge is that matrix arrangement is laid, and one section of bridge is with another
One section of bridge has one section of relatively wide distance in the vertical, as passageway, can pass through for operator；One section of bridge and another section
Bridge has a narrower gap in the horizontal, takes up room to save, and the flank of two sections of bridges is relative the most in the horizontal, phase
To flank between have a gap, this gap is the space worn in this device VERTICAL TUBE, walking mechanism along orbital drive to moving ahead, perpendicular
Straight tube 311 also moves ahead in this gap therewith, will not meet with obstruction.
The device of this patent passes through in the middle of the flank of adjacent two bridges, two-sided moistening and lowering temperature maintenance, once sprays radiation
The part of each half of two bridges, sprays second half during backhaul.
Fixing induction point 43 is arranged on track 41 original position and end position needing to spray bridge, terminates one section of bridge
Spray through the described passageway passed through for operator, device keeps only moving ahead the state not sprayed, and through passageway, arrives
During the position that another section of bridge need to spray, odd-times senses fixing induction point 43, starts again at spray.
Described power-driven system 6 includes that electromotor connects distribution box, and distribution box connects reductor and water pump 2, reductor
Running wheel is connected by gear.During use, first 1) electromotor oiling and water tank are added water；2) starter-generator is powered；3)
Start reductor driven gear and rotate driving walking mechanism walking；4) power-driven system 6 starts water pump, opens Water supply switch valve,
Wet curing beam body；5) maintenance terminates, and closes electromotor.
