Abstract
The invention relates to the technical field of automation, in particular to the technical field of concrete wet spraying, and particularly relates to a concrete wet spraying trolley. According to the concrete wet spraying trolley, a pair of sliding rails which are laid in parallel are arranged, a mechanical arm bearing mechanism can move along the sliding rails, and therefore the work range of a spraying gun mechanism of the wet spraying trolley is widened to the largest extent. Meanwhile, when a mechanical arm retracts, the mechanical arm bearing mechanism can be slid to one end of an entire machine frame, and therefore the length of the entire wet spraying trolley can be reduced. Furthermore, the entire machine frame is arranged on a crawler-type walking chassis so that the wet spraying trolley can work in places with complex environments which are muddy, or uneven or narrow in space and the like, and the overall stability of the wet spraying trolley is increased.
Description
Technical field
The present invention relates to building automation technical field, particularly concrete spraying technical field, is specifically related to a kind of concrete spraying chassis.
Background technology
Concrete sprays and is mainly divided into dry spray, tide spray and wet shot etc.Dry spray is by even the dry mixing by a certain percentage of concrete, cement and accelerating admixture, then pack spraying machine into, make dry gathering materials in flexible pipe, be suspended state and be sent to spray gun with compressed air, mix with water under high pressure at nozzle place again, be ejected at a relatively high speed on scar, it easily produces larger dust, and springback capacity is large, be the valve control by nozzle place owing to adding water, the control ratio of water/binder ratio is more difficult and relevant with the qualification of operator simultaneously.Tide spray is that concrete is added to a small amount of water in advance, makes it to be moist shape, then adds cement and mix and stir, thereby reduce material loading, dust when mixing and stirring and spraying, but a large amount of water is still and adds at shower nozzle place and spray.Wet shot be by concrete, cement and water by design proportion uniform mixing, be sent to shower nozzle place with wet spraying machine, then spray add accelerating admixture on shower nozzle after; Than dry spray and tide spray, the precise control of wet shotcreting water/binder ratio, hydrated cementitious is abundant, quality is easily controlled, dust and springback capacity in course of injection are little, because a dry spray of jetting thickness ratio increases substantially, easily reach the requirement of design jetting thickness, be the current spray technology being widely used simultaneously.
Concrete spraying chassis is a kind of mechanical execution equipment that the fields such as tunnel, road bank protection, building foundation pit, geotechnical engineering, underground construction complete spray technology.Concrete spraying chassis uses hydraulic coupling to be transported to spray gun mechanism by pipeline through the aggregate stirring, and uses compressed air that concrete high velocity jet is gone out, thereby is being subject to spray plane setting and harden, forms concrete supporting.Owing to using concrete spraying chassis to there is the material of saving, save labour, improve construction quality and efficiency, the guarantee constructor advantage such as safely, the application of concrete spraying chassis is more and more general.
In prior art, concrete spraying chassis all adopts automobile chassis or other chassis specials, is running on wheels mode, will often occur being like this difficult to enter more muddy construction plant, or mobile difficulty in muddy place, or move the problems such as difficulty in rugged construction plant; And Wheel type travelling chassis controlling organization more complicated, takes up room large, be difficult to arrange longer stroke jib track, limit once the boundary of works area of the wet shot chassis after in place.
Meanwhile, the mechanical arm of concrete spraying chassis of the prior art is fixed on the top of complete machine vehicle frame conventionally, can not before and after or move left and right; Will cause like this mechanical arm working range not reach capacity or mechanical arm revolution after exceed the problem of complete machine length.
