Intelligent segmental box girder spraying maintenance system

Abstract

The invention provides an intelligent segmental box girder spraying maintenance system which comprises a liquid storage tank, a transverse bottom plate, moving wheels, a telescopic air cylinder, a water suction pump, a water suction pipe, a telescopic corrugated pipe, a water liquid collection frame structure, a rotary water outlet frame structure, an auxiliary positioning frame structure, a transverse water guide pipe, an electromagnetic valve, a mounting frame, a controller and a power switch. The transverse bottom plate is mounted at the lower part of the liquid storage tank through bolts;the water suction pump is mounted at the lower middle part of the front side of the liquid storage tank through bolts, and meanwhile, a water inlet is communicated with the liquid storage tank; and the water suction pipe is in threaded connection with a water outlet of the water suction pump. A fixed pipe is inserted into the upper middle part of a U-shaped mounting frame and is in interference fit with an inner ring of a ball bearing, so that the ball bearing can better rotate a connecting disc and a top spraying pipe on the fixed pipe by a certain angle; and a jacking spring is connected tothe outer side of the positioning rod in a sleeving mode and arranged on the inner sides of a limiting plate and a limiting ring at the same time, and fixing of the connecting disc after angle adjustment is facilitated.

Description

technical field [0001] The invention belongs to the technical field of spray maintenance systems, and in particular relates to an intelligent spray maintenance system for segmental box girders. Background technique [0002] The segmental box girder is prefabricated with C50 high-performance concrete. After the concrete is poured, the reason why it can gradually solidify and harden is mainly due to the hydration of the concrete. Hydration requires proper temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions and its strength is continuously enhanced, the concrete must be cured by spraying. After the concrete is poured, if the climate is hot and the air is dry, the water in the concrete will evaporate too quickly if it is not sprayed and cured in time, resulting in dehydration, which will cause the cement particles that have formed a gel to be unable to fully hydrate and cannot be transformed into a stable cement....

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an intelligent spray maintenance system for segmental box girder to solve the problem that the existing spray maintenance system for segmental box girder does not have the ability to adjust the angle of the top spray rack according to the demand, adjust It is inconvenient to fix after the angle is completed, it is inconvenient to collect the dripping water and it is inconvenient to spray the box girder on one side
