Abstract
The utility model discloses a kind of guide ring of concrete pump piston, comprise oriented loop, it is characterized in that, the sidepiece of described oriented loop has some oil guide slot, and every bar oil guide slot is provided with oil drain out, makes to form the Oil Guide passage communicated with each other between oil guide slot.The utility model structure is simple, and Oil Guide is more smooth and easy.
Description
Technical field
The utility model relates to concrete pump accessory technical field, specifically relates to a kind of guide ring of concrete pump piston.
Background technique
Concrete pump is the to-and-fro motion utilizing piston in cylinder body, concrete batching system is sent to continuously the machinery of building working surface by pipeline.Guide ring has on concrete piston and main oil cylinder piston, because piston (metal) and the inside wall of cylinder (metal) can not directly contact frictions, must there be soft article that piston " is set up ", so guide ring is generally as this support in the inside wall of cylinder of piston.At present, concrete pump piston often there will be Oil Guide and has some setbacks in pumping procedure, and then makes lack of lubrication, finally causes high temperature to make whole pumping system premature wear.For this reason, be necessary to develop a kind of guide ring that can solve described problem.
Summary of the invention
The one that the purpose of this utility model is exactly deficiency in order to solve prior art and provides not only structure is simple, the guide ring of Oil Guide concrete pump piston smoothly.
The utility model adopts following technical solution to realize above-mentioned purpose: a kind of guide ring of concrete pump piston, comprise oriented loop, it is characterized in that, the sidepiece of described oriented loop has some oil guide slot, every bar oil guide slot is provided with oil drain out, for lubricant oil turnover, make between oil guide slot, to form the Oil Guide passage communicated with each other, thus make Oil Guide more smooth and easy.
Further illustrating as such scheme, oil guide slot is arranged along the circumference of oriented loop, forms annular oil guide groove.
Described some annular oil guide grooves are parallel to each other, and the axial direction along oriented loop sets gradually.
Leave interval between described adjacent two annular oil guide grooves and form stalk, every bar is provided with at least three Oil Guide passages vertical with annular oil guide groove on obstructing.
Preferably, the quantity of described annular oil guide groove is 4, and the quantity of stalk is 5, and every bar stalk is provided with 3 Oil Guide passages, and along the circumference of oriented loop, center of circle angle a corresponding between adjacent two Oil Guide passages is 24 °.
The radius of described Oil Guide passage is 2-4mm.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts and open many oil guide slot on existing guide ring, and has Oil Guide passage on every bar stalk, makes oil guide slot communicating together by Oil Guide passage, thus makes Oil Guide more smooth and easy.

Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is plan view of the present utility model.
Description of reference numerals: 1, oriented loop 2, oil guide slot 3, oil drain out 4, stalk.
Embodiment
Below in conjunction with specific embodiment, the technical program is explained in detail.
Embodiment 1
As depicted in figs. 1 and 2, the utility model is a kind of guide ring of concrete pump piston, comprises oriented loop 1, the sidepiece of oriented loop 1 has some oil guide slot 2, every bar oil guide slot 2 is provided with oil drain out 3, for lubricant oil turnover, makes to form the Oil Guide passage communicated with each other between oil guide slot; Oil guide slot is arranged along the circumference of oriented loop, forms annular oil guide groove.Some annular oil guide groove is parallel to each other, and the axial direction along oriented loop sets gradually.Leave interval between adjacent two annular oil guide grooves and form stalk 4, every bar is provided with at least three Oil Guide passages vertical with annular oil guide groove on obstructing.
In the present embodiment, the quantity of described annular oil guide groove is 4, and the quantity of stalk is 5, and every bar stalk is provided with 3 Oil Guide passages, and the radius of Oil Guide passage is 3mm.Along the circumference of oriented loop, center of circle angle a corresponding between adjacent two Oil Guide passages is 24 °.
Embodiment 2
In the present embodiment, the quantity of annular oil guide groove is 3, and the quantity of stalk is 4, and every bar stalk is provided with 5 Oil Guide passages, and the radius of Oil Guide passage is 2mm, and along the circumference of oriented loop, center of circle angle corresponding between adjacent two Oil Guide passages is 24 °.
The technical program adopts and open many oil guide slot on existing guide ring, and has Oil Guide passage on every bar stalk, makes oil guide slot communicating together by Oil Guide passage, thus makes Oil Guide more smooth and easy.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
