Description
Technical field
The utility model is mainly concerned with the pumping mechanism field on concrete pump, concrete mixer and the Vehicle loaded pump, refers in particular to a kind of concrete pumping mechanism of fast changable concrete piston.
Background technique
At present, the concrete pumping mechanism on the concrete pump of domestic and international most producers, concrete mixer and the Vehicle loaded pump comprises concrete cylinder 101, concrete piston assembly 102, middle extension bar 103, piston rod flange 104, water tank 105, tank lid 106, pumping master cylinder 107, non-return valve combination 108 and oil cylinder piston bar 109.The oil cylinder afterbody is located in non-return valve combination 108, is used for being communicated with rod chamber and rodless cavity; Pumping master cylinder 107 links to each other with water tank 105 by bolt, the sponson of oil cylinder piston bar 109 links to each other with piston rod flange 104 by bolt, the two ends of middle extension bar 103 link to each other with piston flange 110 with piston rod flange 104 by screw respectively, piston flange 110 link to each other with concrete piston assembly 102 (referring to shown in Figure 1).Because the stroke of pumping oil cylinder is the stroke of concrete piston assembly 102, under the Placement of diagram 1, even oil cylinder piston bar 109 falls back on the end, concrete piston assembly 102 also still can have been guaranteed the reciprocal proper functioning of mechanism in the inside of concrete cylinder 101.But the motion contact segment of concrete piston assembly 102 generally is to be made of polyamine fat or rubber, and is therefore easy to wear, needs to change frequently.The method step of pumping mechanism shown in Figure 1 being changed concrete piston assembly 102 is as follows: 1) at first close non-return valve combination 108, oil cylinder piston bar 109 is fallen back on the end; 2) dismantle in the middle of the bolt that links to each other with piston flange 110 of extension bar 103 two ends and piston rod flange 104, take out centre extension bar 103; 3) pump oil cylinder piston rod 109 is stretched out slightly, piston rod flange 104 is connected with piston flange 110 by bolt; 4) once more oil cylinder piston bar 109 is fallen back on the end, make the concrete piston assembly 102 that links together with it withdraw from concrete cylinder 101, pull down the bolt of piston flange 110 and piston rod flange 104 then, take out concrete piston assembly 102, change rubber piston (referring to shown in Figure 2).When needs were installed new concrete piston assembly 102, its process was the inverse process of above-mentioned dismounting concrete piston assembly 102.Above-mentioned traditional pumping mechanism constructional device is adopted by numerous concrete pump producers, reliable operation, but dismounting need be taken time about one hour consuming time taking a lot of work.
As shown in Figure 3, in the prior art, it is the pumping mechanism that the able to quickly change of extension bar development changes piston in the middle of the cancellation that the researcher is arranged, it comprises concrete cylinder 201, concrete piston assembly 202, water tank 203, tank lid 204, pumping master cylinder 205, oil cylinder piston bar 206, small plunger 207, small oil tank 208 and garter spring 209, wherein small oil tank 208 is positioned at the tail end of pumping master cylinder 205, small plunger 207 links to each other with the tail end of oil cylinder piston bar 206, oil cylinder piston bar 206 links to each other with concrete piston assembly 202 by garter spring 209, and this garter spring 209 is fixing by bolt 210.This structure has been cancelled the design of middle extension bar, be characterized in making pumping master cylinder 205 afterbodys lengthening, the sealing small oil tank 208 that increases another small plunger 207 and isolate is by discharging the variation of fluid in the small oil tank 208, oil cylinder piston bar 206 is withdrawed from, saved the time of extension bar in the middle of the dismounting.But its concrete piston assembly 202 still adopts more bolt 210 when being connected by garter spring 209 with oil cylinder piston bar 206, needs dismounting one by one.In addition, because small oil tank 208 is to overlap independently choke-out chamber, need to discharge separately or repairing, have seal request (increase and leak link) between small oil tank 208 and the pumping master cylinder 205, and the small plunger 207 that oil cylinder piston bar 206 is installed later there is metal bump to make that this system oil-way complexity, oil cylinder are made complexity, seal request is high.
