Abstract
The present invention relates to a distribution valve for concrete conveying pumps, which is formed by the consolidation of a bow-shaped concrete feeding pipe and an arrow-shaped concrete conveying pipe, wherein the bow-shaped concrete feeding pipe is provided with two concrete discharging ports, and the concrete discharging center distance is two times, namely 2T, of the distance of matched concrete cylinders; the arrow-shaped concrete feeding pipe is provided with a concrete feeding port, two concrete discharging ports are symmetrically distributed, the center of each concrete feeding port is positioned at the right center of the respective concrete discharging port of the bow-shaped concrete feeding pipe, and the distance of the concrete discharging ports is T. The present invention adopts the bow-shaped concrete feeding pipe, and concrete moves in a pipe of the distribution valve; concrete is fed, and concrete is discharged from the arrow-shaped concrete conveying pipe; the distribution valve does not need to move in the concrete like an S pipe distribution valve. Therefore, the distribution valve of the present invention has the advantages that concrete conveying pumps have good concrete sucking performance, transmission components do not contact concrete, and also has the advantages of no concrete gathering zones, little abrasion, long service life, structural simplification and low use cost.
Description
Technical field: the invention belongs to engineering machinery and use the field, be specifically related to the architecture advances of concrete pump with distributing valve.
Background technique: at present, what two concrete cylinder formula concrete pumps used morely is S pipe distributing valve, and its greatest weakness is the suction poor performance, and the S pipe waits the transmission component all to place concrete hopper, in concrete, moves, and quick abrasion, working life is short.In addition,, use concrete pump, need additional lubrication system, stirring mechanism etc., make pump structure quite complicated owing to adopt S pipe distributing valve.
Summary of the invention: technical problem to be solved by this invention is the shortcoming that overcomes existing S pipe distributing valve, provide a kind of and can eliminate the buildup district fully, the suction performance is good, the transmission component do not contact with concrete, can reduce wearing and tearing, long service life, and can simplify the concrete pump distributing valve of conventional concrete transfer pump structure.
The present invention solves the problems of the technologies described above and adopts following technological scheme: it is by bow type supply pipe and arrow type feeding tube fixed composition, bow type supply pipe has two discharge ports, its discharging center distance is that 2 times of supporting concrete cylinder spacing T are 2T, described arrow type feeding tube has a material feeding mouth, two discharge ports are symmetrically distributed, its material feeding mouth is centered close to the center position of bow type supply pipe two discharge ports, and the spacing of its two discharge port is T.
As a further improvement on the present invention, described bow type supply pipe is the circular arc bow shape tube, and the opening material-receiving bucket is arranged at its top, and it is vertical surface that two discharge ports of its underpart are bent into the discharge port plane; Described bow type supply pipe and arrow type feeding tube are affixed by joining plate to be whole.
The present invention adopts the charging of bow type supply pipe, the discharging of arrow type feeding tube, and concrete moves in the distributing valve pipe, distributing valve itself need not to resemble S pipe distributing valve and moves in concrete, therefore, adopt distributing valve of the present invention, concrete pump suction performance is good, no buildup district, the transmission component do not contact with concrete, and wearing and tearing are few, long service life, and simplified structure, reduced user cost.

Embodiment:
Shown in Fig. 1～4, the present invention is by bow type supply pipe 1 and 2 fixed compositions of arrow type feeding tube, bow type supply pipe 1 has two discharge port 1-1,1-2, two discharge port center distance are that 2 times of supporting concrete cylinder spacing T are 2T, described arrow type feeding tube has a material feeding mouth 2-1, be symmetrically distributed two discharge port 2-2,2-3,1-1, the 1-2 center position of the bow type that is centered close to supply pipe two discharge ports of its material feeding mouth 2-1, the spacing of its two discharge port 2-2,2-3 is T.Described bow type supply pipe 1 can be the circular arc bow shape tube, and opening material-receiving bucket 1-3 is arranged at its top, and it is vertical surface that two discharge port 1-1, the 1-2 of its underpart is bent into the discharge port plane.Described bow type supply pipe 1 and arrow type feeding tube 2 is affixed by joining plate 3 be integral body.
Distributing valve of the present invention is user mode and working principle in concrete pump, 5～9 is described below in conjunction with the accompanying drawings:
Shown in Fig. 5～7, distributing valve of the present invention is loaded between the forward and backward plate washer 4,5 of concrete pump, links to each other with left and right push oil cylinder 6,7, and during the transmission and concrete transmission pump work, the concrete cylinder piston rod retreats to sucking, and advancing is output.Bow type supply pipe has two intake ports, feeds concrete alternately for left and right concrete cylinder; Arrow type feeding tube is sent to discharge port with the concrete of concrete cylinder output, reaches the purpose of output.Position shown in Fig. 5～8 is under the effect of left push oil cylinder 6, shifts distributing valve onto the right limit position, and the left side material feeding mouth 1-1 of bow type supply pipe and left concrete cylinder 8 are coincide, and the piston rod of left concrete cylinder 8 retreats, and concrete sucks by left side material feeding mouth.Simultaneously, the material feeding mouth 2-1 of arrow type feeding tube and right concrete cylinder 9 coincide, and the piston rod of right concrete cylinder 9 advances, and concrete exports the discharge nozzle 10 that 2-3 outputs to pump by arrow type feeding tube, finishes when right concrete cylinder pushes, and left side concrete cylinder suction also finishes.At this moment, right push oil cylinder 7 is shifted distributing valve onto left side limit position, the right material feeding mouth 1-2 of bow type supply pipe and right concrete cylinder 9 coincide, piston rod retreats, concrete sucks from right intake port, and simultaneously, the material feeding mouth 2-1 of arrow type feeding tube and left concrete cylinder 8 coincide, piston rod advances, and concrete is transported to the discharge nozzle 10 of pump by the discharge port 2-2 (as shown in Figure 9) of arrow type feeding tube.Left and right hocketing reaches the purpose of continuous delivering concrete.
