Large-span efficient multifunctional concrete sloping surface masonry machine

Abstract

The invention relates to a large-span efficient multifunctional concrete sloping surface masonry machine, comprising a main girder, a running mechanism arranged at two ends of the main girder, a mainreceiving hopper, a feeding belt, a transporting system arranged on an upper discharging car and a lower discharging car and a molding system arranged on the lower discharging car. The molding systemcomprises six or more vibrating bars that is arranged at the lower end of a horizontal reaming cage in a bin and horizontally arranged with a bin outlet, and a slip module arranged at the rear end ofthe vibrating bar, wherein the slip module is internally provided with a panel vibrating motor. The invention increases surface vibration during internal deep-layer vibration, has high concrete compactness and favorable surface pulping effect and is easy to press polish. The invention solves the problems of difficult vibration compact of the concrete and poor surface pulping effect at long intervals in hot and dry climate caused by that the steps of material distribution and vibration used widely in present are carried out in two ways.

Description

technical field [0001] The invention relates to a large-span high-efficiency multifunctional concrete slope masonry machine. technical background [0002] In the world-renowned South-to-North Water Diversion Project started in my country, most of the channel cross-sections are open channel projects, and the surface is made of cast-in-place concrete. Whether it is the east line or the middle line, the amount of canal slope masonry is very large. In order to ensure the construction quality and construction period requirements of the concrete masonry on the slope, each construction unit can only use mechanized construction. [0003] At present, foreign channel lining equipment manufacturers mainly include GOMACO in the United States, Massenza in Italy, G & Z in the United States, Racho Hasson in the United States and Germany. Wirtgen Company; the only channel lining equipment developed by Shandong Water Diversion Engineering Technology Research Center during the construction o...

AI Technical Summary

Problems solved by technology

However, the above equipment has problems such as high cost, heavy weight, difficulty in disassembly and assembly across buildings, high cost of use, and large operation and maintenance costs.

[0004] Currently widely used masonry machines, the vibrating device of the forming system cannot carry out internal deep vibrating and additional surface vibrating, which will affect the compactness of concrete, the effect of surface slurry is not good, and it is not easy to calender

And its cloth, vibrating, and leveling are not one-time forming. Some masonry machines are divided into two steps for cloth and vibrating. In hot and dry climates, if the interval is too long, the concrete is not easy to vibrate and compact, and the surface slurry effect is not good.
