A multi-angle spraying device for high-speed railway prefabricated bridges

Abstract

The invention discloses a multi-angle spraying device for a prefabricated bridge of a high-speed train. The multi-angle spraying device comprises a cushion table, an external spraying system and an internal spraying system; the external spraying system and the internal spraying system are provided with spraying device bodies correspondingly; and each spraying device body comprises a first sprayingdevice main body, a second spraying device main body, a third spraying device main body, a fourth spraying device main body, a fifth spraying device main body, a sixth spraying device main body and aseventh spraying device main body. Through hinged combination of all sets of telescopic rods and the corresponding spray device main bodies, the spraying device adapts to different angles, thus all faces of the spraying device are closely attached to the bridge, the dead corner is avoided through multi-angle spraying, the hardening effect is ensured, the spraying effect is good, and water resources are saved; during sprinkling of curing liquid, a protective film covers evenly, and evaporation of moisture in concrete is effectively prevented; and through the design of combination of a water spraying vehicle and a track, the automation degree is high, and manpower is saved.

Description

technical field [0001] The invention relates to the technical field of high-speed rail construction equipment, in particular to a multi-angle spraying device for high-speed rail prefabricated bridges. Background technique [0002] Most of the high-speed rail prefabricated bridges are poured and hardened by concrete. In order to ensure that the concrete has suitable hardening conditions and its hardness, the concrete must be humidified and cured. The high-speed rail prefabricated bridges are generally box girder structures. Spray trolleys are used, and manual hand-held water spray pipes are used. Adjusting the angle of the nozzle to reduce the spraying on the bridge is labor-intensive and wastes water resources. When the curing solution is sprayed, the spraying effect is likely to be uneven, so that the protective film is incomplete and the curing effect is deteriorated, which needs to be improved.

[0002] Most of the high-speed rail prefabricated bridges are poured and hardened with concrete. In order to ensure that the concrete has suitable hardening conditions and its hardness, the concrete must be humidified and cured. The high-speed rail prefabricated bridges are generally box girder structures. Spraying trolleys and manual hand-held water spray pipes are used for high-speed rail prefabricated bridges. Adjusting the angle of the nozzle to reduce the spraying on the bridge is labor-intensive and wastes water resources. When spraying the curing solution, the spraying effect is likely to be uneven, so that the protective film is incomplete and the curing effect becomes poor. Improvements are needed
