Abstract
The invention relates to automatic paint spraying equipment for a sling of a suspension bridge. The equipment is used for automatic air spraying construction operation of paint on the surface of the zinc-coated wire sling of the suspension bridge.
Description
Technical field
The present invention relates to a kind of automatic paint spraying equipment for sling of suspension bridge, this equipment is used for the coating automatic air spraying application operation on suspension bridge zinc-coated wire hoist cable surface.
Background technology
The modernization suspension bridge partly is made up of cable, Sarasota, anchorage, suspension rod, bridge deck etc.The main supporting member of suspension bridge is a cable, comprises main push-towing rope, hoist cable and accessory structure.Cable mainly bears pulling force, generally uses the high galvanized steel of tensile strength (steel wire, steel strand wires, wirerope etc.) to make.The bridge cable system is the major bearing structures of suspension bridge, is the life rope of bridge.In case funicular system corrodes, consequence is with hardly imaginable.In order to ensure the safety of structure of suspension bridge, must protect cable.The main push-towing rope protection of suspension bridge has formed comparatively mature technique (Chinese invention patent ZL99119397.0), and is used widely.But the hoist cable resist technology of suspension bridge also is not very perfect.At present, using is to adopt the technology of manual brushing to brush anticorrosive paint on the surface of zinc-coated wire hoist cable to protect more widely.
Difference according to suspension cable spanning footpath, adopted and arrived tens of less, how to connect main push-towing rope and steel case beam to hundreds of hoist cables, the hoist cable of different length from several meters high until more than 200 meter high, adopt the technology of manual brushing coating to carry out the hoist cable construction, must carry out the high-altitude cradling, have defectives such as low, the dangerous height of efficiency of construction, construction cost height, the requirement of incompatibility modern chemical industry packing technique.
Summary of the invention
Purpose of the present invention is intended to overcome the deficiency of suspension bridge zinc-coated wire hoist cable manual brushing anticorrosive paint technology, a kind of sling of suspension bridge automatic air spraying equipment is provided, need not the cradling of artificial high-altitude, the application automation to reach, guarantee Safety Management, the purpose of increasing work efficiency.
The present invention is achieved through the following technical solutions:
A kind of automatic paint spraying equipment for sling comprises spray equipment, control device and cage device.
This paint spraying apparatus also comprises external equipment, as air compressor machine and motor hoist.Air compressor machine and motor hoist all are that the suspension bridge those skilled in the art are known.
Described spray equipment comprises tracheae snap joint and spray gun.Described spray equipment also further comprises flexible pipe, air inlet pipe, suction tube, charging basket and coating, acting as of spray equipment by external air compressor machine, the compressed air that air compressor machine provides is connected with whole automatic spraying equipment by tracheae snap joint through air inlet pipe, compressed air is transported to each air gun through flexible pipe again, in case there is compressed air to flow through, the suction tube of spray gun threeway is because the effect of negative pressure is siphoned into spray tip with the coating in the charging basket, and under action of air pressure, spray, coating is compressed air atomizing to the hoist cable surface, thus film-forming.
Described control device comprises magnetic valve, plug, power line, and preferably this control device also comprises limit switch.Magnetic valve is connected with tracheae snap joint, by power line opening/closing magnetic valve, can control compressed air air inlet/stop the supple of gas or steam, limit switch is installed in cage device top, when whole hoist cable automatic spray apparatus is risen to the hoist cable top by motor hoist, limit switch can automatically disconnected power down move the elevator power supply after touching the top, prevents that the hoist cable automatic spray apparatus from damaging.
In addition, described spray equipment can also comprise the air curtain that is connected with the plug of the described control device flexible pipe of giving vent to anger.Be that the compressed air that provides of air compressor machine is connected with whole automatic spraying equipment by tracheae snap joint through air inlet pipe, compressed air enters automatic spraying equipment through air inlet pipe, by multiple-pass joint, is diverted to air curtain give vent to anger flexible pipe and flexible pipe.Described air curtain is given vent to anger flexible pipe can be with compressed air through give vent to anger flexible pipe and by plug of this air curtain, and through spray orifice ejection back formation air curtain, this air curtain can prevent effectively that coating cloud from overflowing from the top of automatic paint spraying equipment for sling, prevents contaminated environment.
Described cage device comprises chassis and flexible pipe.Described chassis is positioned at the bottom of air gun.The cage device can be realized the load-bearing of whole hoist cable automatic spraying equipment and fix spray equipment and the function of control device.In order to guarantee that hoist cable vertically sprays, thereby realize best spraying effect, but the position that preferred described cage device contacts with hoist cable in the bottom that is positioned at the chassis can also comprise fairlead and reducing guide ring.But the diameter of reducing guide ring can be regulated according to the diameter of hoist cable.But the reducing guide ring is positioned on the fairlead, can be provided with one fully at the two ends up and down of fairlead, can slide along with moving up and down of cage device.
Described cage device also comprises dustproof cotton, pull rope, snap close, hanger and railing.
Difference according to the hoist cable diameter, but by selecting for use the reducing guide ring and the fairlead (can live hoist cable by the snap close retaining ring at each position on opened/closed fairlead and the chassis, thereby support whole device) that are fit to this hoist cable diameter that whole hoist cable automatic spraying equipment is vertically depended on hoist cable; It is cotton along railing tight seal parcel cage device to prevent dust again, preventing that in the coating aerial spraying process, the coating cloud of generation splashes to the pollution of environment, simultaneously ventilatively prevents to produce malleation; The external equipment motor hoist can start motor hoist like this through the hanger of pull rope by fixed pivot (being installed in the fixed pulley on the main push-towing rope) the connection cage device top on hoist cable top, controls the rising/decline of the automatic coating equipment of whole hoist cable.Because motor hoist can be controlled the gait of march of pull rope, thereby has controlled the automatic coating equipment rising/decrease speed of hoist cable.When automatic paint spraying equipment for sling carried out spraying operation, the direct of travel of equipment was for from top to down, and fall off rate is 8～12m/min, most preferably 10m/min.
Common one group of hoist cable is made up of the equidistant vertical hoist cables of 4 or 2, and different chassis (seeing Fig. 2 a, Fig. 2 b, Fig. 2 c) can adapt to the hoist cable of different spacing, different-diameter.Make automatic paint spraying equipment for sling with circular base plate, rectangle chassis four spray guns can be installed; With the automatic paint spraying equipment for sling that the triangle chassis makes three spray guns can be installed.Material guide hole on the chassis can compile the unnecessary paint vehicle in the spraying process, and flow back into again in the charging basket, to utilize again.
