Description
Technical field:
The present invention relates to construction implement, be specifically related to improvement concrete pump.
Background technology:
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, conveyor, door machine or tower machine to add construction machinery 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 plant limitation reason uses above-mentioned construction machinery 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.
Summary of the invention:
Technical problem to be solved by this invention is how to carry three-graded concrete by concrete pump, but its delivery 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 invention is that technical 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 element of controlling above-mentioned each driving member 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 shafts that are arranged in parallel and drive rotated by stirring motor in the described hopper, two shaft direction of rotation are opposite, are respectively equipped with stirring vane on it, and this stirring vane can be helical mixing blade.Transmission and concrete transmission cylinder diameter of the present invention requires to be designed to 200mm～350mm according to aggregate, and the concrete charging aperture 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 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.

The specific embodiment;
The present invention is the improvement of being done on the existing concrete pump, it be primarily aimed at present existing concrete pump because of the problems referred to above can't the pumping three-graded concrete the design carried out of defective.As Fig. 1, shown in Figure 2, the present invention includes diesel engine 1, hydraulic oil container 2, gate valve 3, hopper 4, stirring motor 5, underframe 6, vehicle bridge 7, main valve piece 9, main oil pump 10, transmission and concrete transmission cylinder 11, pumping system 14 and the control device 8 of controlling above-mentioned each actuated element action, wherein diesel engine 1 and hydraulic oil container 2 are placed on plane on the vehicle frame 6, diesel engine 1 is positioned at back location, hydraulic oil container 2 is positioned at the forward position, hopper 4 is positioned at vehicle frame 6 anterior locations, its below is connected with carries cylinder 11, gate valve 3 is located at and is carried between cylinder 11 and the hopper 4, pumping system 14 is positioned at below the vehicle frame 6, switch board 8 is established in vehicle frame 6 sides, each control element signal lamp and switch can be loaded in it, directive wheel 12 is positioned at vehicle frame 6 afterbodys, and this vehicle frame 6 is fixed on the vehicle bridge 5.The present invention is characterised in that described diesel engine 1 sets up two separately, is loaded on rear portion, plane on the underframe 6 side by side.Setting has two benefits like this, and first can solve the problem of a diesel powered deficiency, strengthens pumping power, can avoid adopting the diesel engine of a big power to cause the larger-size defective of complete machine simultaneously; The use of the second, two diesel engine 1 can make it have complementarity.When wherein a certain diesel engine broke down, another diesel engine still can work on, and can guarantee carrying out continuously of pumping, to avoid causing the not smooth of pipeline or obstruction owing to the diesel engine Halfway Stopping makes to the cement solidifies in the conveyance conduit.The present invention is provided with two main oil pumps 10 according to the correspondence that is provided with of diesel engine 1, connects with two diesel engines 1 respectively, and two main oil pumps 10 join with main valve piece 9 again, and the action of pumping system 14 is by 9 controls of main valve piece.
As Fig. 2, Fig. 3, shown in Figure 4, for realizing the forced feed function, the present invention is provided with two shafts 13 that are arranged in parallel in hopper 4, is driven by two stirring motors 5 respectively and rotates, and two shafts, 13 rotation directions can be identical or opposite.Adopt two shafts 13 of relative reverse rotation can force feeding to be carried in the cylinder 11 concrete in the concrete pump hopper 4, help improving the suction efficiency of concrete pump from the rotation of two side direction centers.On two shafts 13, stirring vane 15 is housed respectively, the shape of this blade can be helical mixing blade.
For adapting to three graded aggregate requirements, transmission and concrete transmission cylinder 11 diameters of the present invention are designed to 200mm～350mm, and 4 times charging apertures of its hopper are rectangle, and length is 300mm～400mm, and width is 250mm～350mm.Can strengthen the handling capacity of concrete pump like this, more help the big concrete of aggregate diameter by charging aperture, and make transmission and concrete transmission cylinder 11 finish concrete suction and pumping.
In sum, but the present invention's big forced feed that is a kind of mixing power and concrete pump that can the uninterrupted pumping three-graded concrete simple in structure, easy to use.
