Abstract
A distribution valve for concrete pump comprises an arch feeding pipe fixed with an arrow-like conveying pipe, wherein the arch feeding pipe is provided with two material outlets, with the interval between the outlet centers is twice the interval T of every two matched concrete vats, i.e. 2T, the arrow-like conveying pipe is provided with a feeding mouth and two material outlets which are arranged symmetrically, wherein the center of the feeding mouth is positioned on the right center of the two material outlets of the arch feeding pipe, and the interval between the two material outlets is T. The utility model adopts the arch feeding pipe, the concrete moves inside the distribution valve pipe and the material is fed, the material is sent out through the arrow-like conveying pipe, and the distribution valve needs on movement in the concrete, which is needed by the S distribution valve. Therefore, the distribution valve provided by the utility model has the good feature of good performance of material absorption of the concrete conveying pump, no material deposit area, no contact between the driving components and the concrete, little abrasion, long life span, simplified structure and decreased cost.
Description
Technical field: the utility model belongs to construction machinery and equipment and uses the field, is specifically related to the structural development of concrete pump with distributing valve.
Background technology: 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 parts all to place concrete hopper, in cement concrete, moves, and quick abrasion, service life is short.In addition,, use concrete pump, need additional lubrication system, rabbling mechanism etc., make pump structure quite complicated owing to adopt S pipe distributing valve.
Summary of the invention: technical problem to be solved in the utility model 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 parts do not contact with cement concrete, can reduce wearing and tearing, long service life, and can simplify the concrete pump distributing valve of conventional concrete transmission pump structure.
The utility model solves the problems of the technologies described above and adopts following technical scheme: it is by bow type feed pipe and arrow type feed pipe fixed composition, bow type feed pipe has two discharging openings, its discharging center-to-center distance is that 2 times of supporting concrete cylinder spacing T are 2T, described arrow type feed pipe has an inlet point, two discharging openings are symmetrically distributed, its inlet point is centered close to the center position of bow type feed pipe two discharging openings, and the spacing of its two discharging opening is T.
As further improvement of the utility model, described bow type feed pipe is the circular arc bow shape tube, and the opening receiving hopper is arranged at its top, and it is vertical surface that two discharging openings of its underpart are bent into the discharging opening plane; Described bow type feed pipe and arrow type feed pipe are affixed by gusset piece to be whole.
The utility model adopts the charging of bow type feed pipe, the discharging of arrow type feed pipe, and cement concrete moves in the distributing valve pipe, distributing valve itself need not to resemble S pipe distributing valve and moves in cement concrete, therefore, adopt distributing valve of the present utility model, concrete pump suction performance is good, no buildup district, the transmission parts do not contact with cement concrete, and wearing and tearing are few, long service life, and simplified structure, reduced use cost.

The specific embodiment:
Shown in Fig. 1～4, the utility model is by bow type feed pipe 1 and 2 fixed compositions of arrow type feed pipe, bow type feed pipe 1 has two discharging opening 1-1,1-2, two discharging opening center-to-center distances are that 2 times of supporting concrete cylinder spacing T are 2T, described arrow type feed pipe has an inlet point 2-1, be symmetrically distributed two discharging opening 2-2,2-3,1-1, the 1-2 center position of the bow type that is centered close to feed pipe two discharging openings of its inlet point 2-1, the spacing of its two discharging opening 2-2,2-3 is T.Described bow type feed pipe 1 can be the circular arc bow shape tube, and opening receiving hopper 1-3 is arranged at its top, and it is vertical surface that two discharging opening 1-1, the 1-2 of its underpart is bent into the discharging opening plane.Described bow type feed pipe 1 and arrow type feed pipe 2 is affixed by gusset piece 3 be integral body.
Distributing valve of the present utility model is running condition and principle of work in concrete pump, 5～9 is described below in conjunction with the accompanying drawings:
Shown in Fig. 5～7, distributing valve of the present utility model 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 feed pipe has two charging holes, feeds cement concrete alternately for left and right concrete cylinder; Arrow type feed pipe is sent to discharging opening with the cement 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 end position, and the left side inlet point 1-1 of bow type feed pipe and left concrete cylinder 8 are coincide, and the piston rod of left concrete cylinder 8 retreats, and cement concrete sucks by left side inlet point.Simultaneously, the inlet point 2-1 of arrow type feed pipe and right concrete cylinder 9 coincide, and the piston rod of right concrete cylinder 9 advances, and cement concrete exports the discharge nozzle 10 that 2-3 outputs to pump by arrow type feed pipe, 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 end position, the right inlet point 1-2 of bow type feed pipe and right concrete cylinder 9 coincide, piston rod retreats, cement concrete sucks from right charging hole, and simultaneously, the inlet point 2-1 of arrow type feed pipe and left concrete cylinder 8 coincide, piston rod advances, and cement concrete is transported to the discharge nozzle 10 of pump by the discharging opening 2-2 (as shown in Figure 9) of arrow type feed pipe.Left and right hocketing reaches the purpose of continuous delivering concrete.
