Abstract
The utility model relates to a concrete pump truck conveying cylinder piston which comprises a piston body, a piston connecting rod and sealing rings. The piston is arranged in a conveying cylinder, two sealing rings are arranged between the piston and the conveying cylinder, the distance D between the two sealing rings is 350-450mm, the sealing rings are O-shaped sealing rings, and the piston connecting rod and the piston are of an integrated structure. The concrete pump truck conveying cylinder piston has the advantages that the structure is simple, using is convenient, piston replacing frequency is greatly lowered, the sealing effect is good due to the two sealing rings, repair time is saved, labor productivity is improved, and cost is lowered.
Description
Technical field
The utility model relates to a kind of concrete mixer piston of conveying cylinder.
Background technique
In the concrete pump truck pumping system, piston of conveying cylinder plays very main reusing, and it is the vitals to building concrete conveyance.The piston that pump truck carries is aluminum alloy material, and only is provided with a seal ring on piston, and piston, through work after a while, will damage because aluminum alloy material is hard not, and the phenomenon of leakage of oil often appears in one seal ring.2 pistons of each pump truck, our mixing plant has 5 pump trucks, totally 10 pistons, 8000 yuan, each piston, replacing in every 6 months once needs 400000 yuan.Not only consume the part expense and affect production waste of manpower, material resources between the stage of replacement.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of concrete mixer piston of conveying cylinder, extends the working life of piston.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of concrete mixer piston of conveying cylinder, comprise piston, piston rod, seal ring, described piston is arranged on to be carried in cylinder, be provided with two seal rings between piston and conveying cylinder, two seal ring spacings are D=350-450mm, described seal ring is the O RunddichtringO, and piston rod and piston are the integral type structure.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, easy to use, greatly reduce piston and change number of times, seal ring is the two seals circle, obturation effect is good.Not only saved the repair time, raised labour productivity, but also played the effect reduced costs.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-carries cylinder 2-piston 3-piston rod 4-seal ring.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 1, a kind of concrete mixer piston of conveying cylinder, comprise piston 2, piston rod 3, seal ring 4, described piston 2 is arranged on to be carried in cylinder 1, be provided with two seal rings 4 between piston 2 and conveying cylinder 1, two seal ring 4 spacings are D=350-450mm, and described seal ring 4 is the O RunddichtringO, and piston rod 3 is the integral type structure with piston 2.
Embodiment:
Piston 2 is made into integral structure with piston rod 3, by No. 45 modified materials of steel, is made, and piston 2 is provided with the twice parallel groove, and an O RunddichtringO respectively is installed in the twice groove, and flute pitch is D=400 ± 20mm.Replace original aluminum alloy material by No. 45 modified materials of steel, strengthen piston 2 intensity, adopt two seals circle 4 to strengthen sealing effect, prevent leakage of oil.
The utility model is simple in structure, easy to use, greatly reduces piston and changes number of times, and seal ring is the two seals circle, and obturation effect is good.Not only saved the repair time, raised labour productivity, but also played the effect reduced costs.
