Abstract
The invention relates to an integral high wear-resistant concrete pump piston comprising a piston body. A step hole is formed in the middle of the piston body; one end of the piston body is provided with a piston lip; a U-shaped groove is arranged under the piston lip; three protrude bars are arranged outside the piston body; each protruding bar is divided into three equal sections; a gap is formed between each two sections with the interval of 5mm; and an oil groove is formed between each two adjacent protruding bars. The integral structure requires low manufacturing cost, possesses long service life and can improve production efficiency.
Description
Technical field
The present invention relates to a kind of concrete pump piston, be specifically related to a kind of integral type concrete pump piston.
Background technique
The concrete pump piston of present use is split type, comprises piston and guide ring.In actual use, it is high to there is manufacture cost in it, and the lubricant oil property moved is bad, when 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 affect manufacturing efficiency, line service amount is large.In addition, because it is split-type structural, the coaxality of carrying in conveying cylinder is not high, and impact normally works.
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, to provide a kind of integral structure, 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 of the present invention, it comprises piston only, in the middle part of described piston only, be provided with step hole, piston lip is provided with in described piston only one end, below described piston lip, be provided with U-type groove, be provided with raised line in described piston only outside, described raised line has three, described raised line is evenly divided into three sections, be provided with gap between every section, the distance in gap is 5mm, is oil groove between adjacent two described raised lines.
Described step hole is divided into first step hole and second step hole, their forming station hierarchic structures, and the diameter in first step hole is less than the diameter in second step hole.
Described step hole runs through described piston only.
Described piston lip slopes inwardly setting.
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 present invention compared with prior art, its remarkable advantage is: the present invention adopts integral structure, solve the problem with secondary piston and guide ring separate machined, reduce cost of production, and owing to being integral structure, ensure the coaxality that piston is good in the process of conveying, and before can not producing during split-type structural, the situation that guide ring comes off, substantially increase manufacturing efficiency and working life, first step hole and second step hole adopt staircase structural model, ensure good associativity, described raised line is evenly divided into three sections, gap is provided with between every section, this ensure that the mobility of lubricant oil is better, the realistic usage requirement of this product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below by drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, integral type high abrasion concrete pump piston of the present invention, it comprises piston only 1, in the middle part of described piston only 1, be provided with step hole 2, piston lip 3 is provided with in described piston only 1 one end, below described piston lip 3, be provided with U-type groove 4, be provided with raised line 5 in described piston only 1 outside, described raised line 5 has three, described raised line 5 is evenly divided into three sections, be provided with gap 6 between every section, the distance in gap 6 is 5mm, is oil groove 7 between adjacent two described raised lines 5; Described step hole 2 is divided into first step hole 8 and second step hole 9, their forming station hierarchic structures, 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; Described piston lip 3 slopes inwardly setting.The present invention adopts integral structure, solve the problem with secondary piston and guide ring separate machined, reduce cost of production, and owing to being integral structure, ensure the coaxality that piston is good in the process of conveying, and before can not producing during split-type structural, the situation that guide ring comes off, substantially increase manufacturing efficiency and working life, first step hole and second step hole adopt staircase structural model, ensure good associativity, described raised line is evenly divided into three sections, gap is provided with between every section, this ensure that the mobility of lubricant oil is better, the realistic usage requirement of this product.
The invention provides a kind of thinking and method; the method and access of this technological scheme of specific implementation is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, some improvements and modifications can also be made; these improvements and modifications also should be considered as protection scope of the present invention, and all available prior art of each constituent element not clear and definite in the present embodiment is realized.
