Abstract
Disclosed is a three-graded concrete pump, which comprises two diesel engines, a hopper and a stirring motor. The utility model is characterized in that the two diesel engines are arranged in parallel on a pedestal and respectively connected with two correspondingly arranged main oil pumps that are connected with main valve blocks; two stirring shafts are arranged in parallel and driven for rotation by the stirring motor in the hopper; the two stirring shafts rotate in opposite directions; a stirring blade which can be helix-shaped is arranged on each stirring shaft. The diameter of the feeding cylinder of the concrete pump is from 200mm to 350mm; the inlet orifice of concrete is rectangle, with the length from 300mm to 400mm and the width from 250mm to 350mm. The adoption of two diesel engines in the utility model solves the problem of insufficient power supplied by the existing one diesel engine, the pumping power is largely strengthened, and the pumping process can be ensured to be consecutive. The adopted double-shaft stirring enables the pumping stirring force to be enhanced and the evenness degree to be improved, so that the problem of high resistance of concrete pump stirring and the concrete in the hopper of the concrete pump can be forced into the feeding cylinder, therefore the indrawing efficiency of the concrete pump can be improved.
Description
Technical field:
The utility model relates to construction implement, is specifically related to the improvement to concrete pump.
Background technique:
Use three-graded concretes at present in the large hydraulic engineering in a large number, its construction is main to be relied on tower belt crane, belt conveyer, door machine or tower machine to add construction plant such as cage to carry three-graded concrete, but some construction point (as tunnel, tower, post, bridge and water project etc.) is because the construction site limitation reason uses above-mentioned construction plant to be difficult to finish concrete conveying.Current domestic and international concrete pump can only be carried two gratings (concrete maximum aggregate diameter is 40mm) concrete, because three gratings (concrete maximum aggregate diameter is 80mm) concrete aggregate diameter is big, concrete flowability is poor, thereby can't finish pumping.
The model utility content:
Technical problem to be solved in the utility model is how to carry three-graded concrete by concrete pump, but its transfer pump is answered that mixing power is big, the high forced feed of mixing evenness and can realize uninterrupted pumping.
Technical problem of the present utility model is that technological scheme solves below adopting.It comprises diesel engine, hydraulic oil container, gate valve, hopper, stirring motor, underframe, main valve piece, main oil pump, transmission and concrete transmission cylinder and the control unit of controlling above-mentioned each driving component action, it is characterized in that described diesel engine establishes two, be divided on the underframe side by side, connect with two main oil pumps of corresponding setting respectively, two main oil pumps and main valve piece join; Be provided with two stirring shafts that are arranged in parallel and drive rotated by stirring motor in the described hopper, two stirring shaft sense of rotation are opposite, are respectively equipped with mixing blade on it, and this mixing blade can be helical mixing blade.The utility model transmission and concrete transmission cylinder diameter requires to be designed to 200mm～350mm according to aggregate, and the concrete material feeding mouth is designed to rectangle, and length is 300mm～400mm, and width is 250mm～350mm.
Adopt the concrete pump of technique scheme, owing to adopt two diesel engines, solved the difficult problem of a diesel powered deficiency, pumping power strengthens greatly, and can guarantee carrying out continuously of pumping process.Adopt twin shaft to stir the pumping mixing power is strengthened, concrete in the hopper rotates in opposite directions by two stirring shafts, the uniformity improves, can solve the big problem of stirring resistance of concrete pump, can force feeding to be carried in the cylinder concrete in the concrete pump hopper simultaneously, help improving the suction efficiency of concrete pump.
