The hawser airbag heating device comprises a heating layer with heating wires, and a heating and pressurizing cushion, wherein the heating and pressurizing cushion is composed of the heating layer, a heat insulation layer and an air bag, and the heat insulation layer and the air bag are sequentially stacked on one side of the heating layer. A plurality of annular tightening strips are arranged on the air bag at intervals, each annular fastening strip fastens from one side edge of the air bag to the other side edge, one end of each annular fastening strip is connected with a tension buckle, and the other end is provided with a fastening strip extending portion extending out of the side of the air bag to be fastened with the tension buckle. The heating and pressurizing cushion is provided with a sensor unit electrically connected with a controller. Compared with the prior art, the heating surface is stressed uniformly, and the problem that an existing heating device is easy to cause non-uniform stress on overlapped positions and loose adhesion to influence sealing effect and increase reworking rate when heating hog-press self-bonding adhesive tape winding on a hawser is solved.
Description
Technical field
The present invention relates to and belong to bridge construction field of engineering technology, especially a kind of instrument for carrying out thermal welding to the adhesive tape that main rope of suspension bridge is wound around.
Background technology
Main push-towing rope is one of most important primary structure member of suspension bridge, is called as " lifeline ", and it is chronically exposed in atmospheric environment, undergos the erosion of various adverse environmental factors.And main push-towing rope is non-exchange component, therefore the life-span of main push-towing rope directly affects the service life of suspension bridge.The anti-corrosion mode of most of main rope of suspension bridge is for case to be: steel wire carries out zinc-plated process, and coating putty after main push-towing rope is shaped also is wound around round wire, finally at its external coating composite coating.Carry out anticorrosion, but under harsh environments, be especially used in the structure of stressed complexity, these composite coatings are easy to cracking, once cracking, the impurity such as moisture will invade its internal corrosion main push-towing rope.Therefore, it is most important that the anticorrosion sheath of outermost layer is set, extraneous rugged environment can be completely cut off, effectively prevent the intrusion of moisture.Usual use hot pressing self-adhesive tape is wrapped on main push-towing rope, then by the mode of heating, hot pressing self-adhesive tape is bonded on main push-towing rope as anticorrosion sheath.At present the overlap joint mouth of heater to hot pressing self-adhesive tape adopting air-heater or heater strip is housed easily heats more, easily there is overlap joint mouth unbalance stress in this mode of heating, bonding not labor affects sealing effectiveness, adhesive tape easily gets loose phenomenon, rework rate is high, not only reduce construction quality, also incur loss through delay the construction period.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cable air bag heater, easily occurs overlap joint mouth unbalance stress to solve existing heater to the hot pressing self-adhesive tape heating be wrapped on main push-towing rope, bonding not labor and the high problem of rework rate.
The technical scheme that technical solution problem of the present invention adopts is: this cable air bag heater comprises the zone of heating being provided with heater strip, by described zone of heating and successively folded be located at described zone of heating one side heat-insulation layer and the heating that forms of air bag to pressurize liner; Described air bag is interval with many annular tightenings; Annular tightening described in every bar from described air bag one lateral edges to opposite side edge, one end of described annular tightening is connected with pulling force latch closure, and the other end of described annular tightening is provided with the tightening extension stretching out described air bag side and described pulling force latch closure and be interlockingly connected; Described heating pressurization liner is provided with the sensor unit be electrically connected with controller.
In above-mentioned cable air bag heater technical scheme, technical scheme can also be more specifically: when described heating pressurization liner is buckled on main push-towing rope cylindrical around cover, form the axially open that a width s is 9 millimeters ~ 11 millimeters between described heating pressurization liner one side and another side.
Further: described air bag is provided with the air inlet pipe be communicated with source of the gas and the blast pipe being provided with relief valve, and described air bag is provided with Pressure gauge.
Further: described heating pressurization liner is equipped with airbag restraint liner plate in dual-side edge, is provided with handle at described airbag restraint liner plate.
Further: described sensor unit has temperature sensor and humidity sensor, the control end of described temperature sensor and the control end of described humidity sensor are electrically connected with described controller respectively by wire.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: during heating, first heating pressurization insert is contained in and is wound with on the main push-towing rope cylindrical of hot pressing self-adhesive tape, and the tightening extension on pulling force latch closure and annular tightening is interlocked, the gas of band pressure is passed into by the air inlet of air inlet pipe, air bag is made to be full of air pressure, pressurize when heating hot pressing self-adhesive tape simultaneously, the hot pressing self-adhesive tape on main push-towing rope is made to be subject to the normal pressure of air bag applying, thus it is even at the effect lower stress of high temperature, pressure to reach multi hot press self-adhesive tape, and effective thermal welding, simultaneously by controller setting heating-up temperature and heat time, when heating, heat time reaches design temperature and after the time, open relief valve releasing compressed gas, again heating pressurization insert is rotated an angle, heated again by the main push-towing rope of heating pressurization liner to same sections, pressurization, its objective is and thermal welding is carried out to the hot pressing self-adhesive tape at axially open place, relief valve releasing compressed gas pine is opened when acid extraction reaches setting value, open pulling force latch closure, take off the thermal welding that heating pressurization liner then completes main push-towing rope first sections, heating pressurization liner now can be used to carry out the thermal welding of a lower main push-towing rope sections, circulate successively, adhesive tape overlap joint mouth uniform force, firmly bonding, there will not be the phenomenon that gets loose, guarantee sealing property, without the need to doing over again, not only improving construction quality, also shortening the construction period.
