Abstract

The utility model relates to an integrated high-abrasion-resistance concrete pump piston. The integrated high-abrasion-resistance concrete pump piston comprises a piston body, wherein a step hole is formed in the middle of the piston body, a piston lip is arranged at one end of the piston body, a U-shaped groove is formed below the piston lip, three protruding strips are arranged outside the piston body, each protruding strip is divided into three equal sections, a gap exists between every two adjacent sections, the length of each gap is 5 mm, and an oil tank is arranged between every two adjacent protruding strips. The integrated high-abrasion-resistance concrete pump piston is of the integrated structure, the manufacturing cost is low, the service life is long, and the production efficiency is improved.

Description

Integral type high abrasion concrete pump piston
Technical field
The utility model relates to a kind of concrete pump piston, is specifically related to a kind of integral type concrete pump piston.
Background technique
The concrete pump piston using is now split type, comprises piston and guide ring.In actual use, it exists manufacture cost high, and the moving property of lubricant oil is bad, the in the situation that of conveying high-pressure; guide ring can be separated with concrete head assembly, causes obscission, will cause unexpected shutdown like this; concrete send and cannot normally carry out, and affects manufacturing efficiency, and line service amount is large.In addition, because it is split-type structural, the coaxality of carrying in carrying cylinder is not high, and impact is normally worked.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of integral structure is provided, low cost of manufacture, long service life, the high abrasion concrete pump piston of enhancing productivity.
Technological scheme: in order to solve the problems of the technologies described above, integral type high abrasion concrete pump piston described in the utility model, it comprises piston only, at described piston only middle part, is provided with step hole, in described piston only one end, be provided with piston lip, below described piston lip, be provided with U-shaped groove, in described piston only outside, be provided with raised line, described raised line has three, described raised line is evenly divided into three sections, between every section, be provided with gap, the distance in gap is 5mm, between adjacent two described raised lines, is oil groove.
Described step hole is divided into first step hole and second step hole, and they form staircase structural model, and the diameter in first step hole is less than the diameter in second step hole.
Described step hole runs through described piston only.
The setting that slopes inwardly of described piston lip.
The width of described raised line is 4mm, and the width of oil groove is 6mm, and the diameter in described second step hole is 71mm, is highly 35mm, and the diameter in described first step hole is 61mm.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model adopts integral structure, solved the problem with secondary piston and guide ring separate machined, reduced cost of production, and owing to being integral structure, guarantee piston good coaxality in the process of carrying, and before can not producing during split-type structural, the situation that guide ring comes off, manufacturing efficiency and working life have greatly been improved, first step hole and second step hole adopt staircase structural model, guarantee good associativity, described raised line is evenly divided into three sections, between every section, be provided with gap, the mobility that has guaranteed like this lubricant oil is better, the realistic usage requirement of this product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by drawings and Examples, the utility model is further described.
As shown in Figure 1, integral type high abrasion concrete pump piston described in the utility model, it comprises piston only 1, at described piston only 1 middle part, is provided with step hole 2, in described piston only 1 one end, be provided with piston lip 3, below described piston lip 3, be provided with U-shaped groove 4, in described piston only 1 outside, be provided with raised line 5, described raised line 5 has three, described raised line 5 is evenly divided into three sections, between every section, be provided with gap 6, the distance in gap 6 is 5mm, between adjacent two described raised lines 5, is oil groove 7; Described step hole 2 is divided into first step hole 8 and second step hole 9, and they form staircase structural model, and the diameter in first step hole 8 is less than the diameter in second step hole 9; Described step hole 2 runs through described piston only 1; The setting that slopes inwardly of described piston lip 3.The utility model adopts integral structure, solved the problem with secondary piston and guide ring separate machined, reduced cost of production, and owing to being integral structure, guarantee piston good coaxality in the process of carrying, and before can not producing during split-type structural, the situation that guide ring comes off, manufacturing efficiency and working life have greatly been improved, first step hole and second step hole adopt staircase structural model, guarantee good associativity, described raised line is evenly divided into three sections, between every section, be provided with gap, the mobility that has guaranteed like this lubricant oil is better, the realistic usage requirement of this product.
The utility model provides a kind of thinking and method; method and the approach of this technological scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection domain of the present utility model, in the present embodiment not clear and definite each constituent element all available prior art realized.
