Description
Technical field
The invention belongs to high-speed rail Construction of Precast Box Beam technical fields, and in particular to one kind is removed for box girder formwork automatically grinding
The integrated device of dirt and spraying.
Background technique
With the continuous development that China's high-speed rail is built, large scale prefabricated box beam has become the important component of engineering construction,
Box beam is by the way that after beam making field completion is prefabricated, using bridge entrucking on lifting beam machine bale handle, beam car, which transports, sets up position, last benefit
The overall process of paving frame will be completed on box beam erection to the bridge pier finished of having constructed with Bridge Erector.It can not only using prestress box beam
It accelerates construction progress, and can realize standardized production, substantially increase the controllability of bridge quality.But with prestress box beam
The continuous increase of structure, often punching block plate surface remains the dirts such as concrete residue even iron rust unavoidably after one moulding box beam of prefabricated completion
Object is contaminated, needs to be cleaned out before the secondary use of template.Manual operation is relied primarily on for the cleaning of steel form at present,
Since the punching block board size of high-speed rail prefabricated case beam is big or even length can be 40 meters big, so that entire polishing operation is extremely complex, cleaning
Difficulty is big；Importantly, also needing the spraying operation for carrying out release agent to template surface after the completion of cleaning, it can be seen that template is clear
The work load of reason maintenance and spraying operation personnel are heavy, it is often more important that fully rely on manually-operated constructor for it is subjective because
Element is more obvious, the situation not in place cleared up and sprayed easily occurs, leading to later period prefabricated box -beam, there are the different degrees of flaws
Defect influences the presentation quality of prefabricated case beam.
Application No. is 201710559812.3 patents of invention to disclose a kind of box girder formwork surface automatically grinding equipment, energy
It is enough to realize that substitution manual operation removes box girder formwork side wall iron rust, the effect improved labor efficiency.But the invention equipment is very multiple
Miscellaneous, various rod pieces, lead screw interlaced arrangement bring larger difficulty to the maintenance in use process；Importantly, this sets
The standby cleaning polishing function of only having template, and it is helpless for next needing the release agent carried out to spray, it is seen that in fact
It is lower with property, it can not effectively meet the allegro construction speed in precast beam field.
