Description
Technical field
The present invention relates to a kind of joint, particularly a kind of for synchronous macadam seal paver can locate mode Multi-path rotary joint.
Background technique
Synchronous pavement surface dressing is in order to reduce construction cost, improves operation quality and efficiency, based on aggregate chips spread and pitch sprinkling, utilizes the new features of Current Highway construction material, and the highway maintenance technology of new generation producing.The road surface that utilizes this technology to lay has the characteristics such as highly abrasion-resistant, anti-skidding, waterproof.U.S.'s data shows, carries out synchronous surface dressing maintenance in basic unit, can prolonging service life of pavement more than 10 years; Meanwhile, the research of Australian appropriate authority shows, Synchronous pavement surface dressing can make the serious road life of damage comparison increase by 10～15 years.
On traditional synchronous macadam seal paver, its asphalt-spraying Placement is straight-through type swivel joint; An i.e. import and an outlet, thus in the time realizing the complete alternation of pitch in spray line, need to increase a lot of pipes, very complicated and install very inconvenient; And owing to there is no the design of locating function, can easily not make swivel joint be fixed on the work of a certain position.Therefore,, for the joint of this kind of asphalt-spraying, also require further improvement.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide the one can locate mode Multi-path rotary joint, and simple in structure, can realize the pitch complete alternation of every section of spreading tube and there is locating function.
The technical solution used in the present invention is such: one can locate mode Multi-path rotary joint, comprise major joint pipe, on described major joint pipe, be socketed solid of rotation and by positioning device being set on major joint pipe, solid of rotation fixed, left section of upper secondary spray line being communicated in major joint pipe that arranges of this solid of rotation, secondary feed back pipe is set on right section, major joint pipe right-hand member arranges main feed back pipe, the feed back chamber being communicated with main feed back pipe and secondary feed back pipe is set in right section of corresponding major joint tube wall of solid of rotation, and this feed back chamber also connects a total feed back pipe.
Six via design schemes of the present invention, make pitch after the import of major joint pipe right-hand member enters, be divided into two branch roads: a branch road is connected to main spraying pipeline from left end outlet, finally by main feed back pipe feed back; Another branch road is exported from secondary spray line, finally by secondary feed back pipe feed back.After pitch feed back on these two branch roads has converged, then pass back into asphalt tank by total feed back pipe together.
As preferably, the positioning hole on described solid of rotation end face has four, and every 90 degree distribute one, and correspondingly, main feed back pipe and the interval of secondary feed back pipe on circumference are also 90 degree.
This preferred structure just can be located after realizing every rotation 90 degree of solid of rotation, meets practice of construction requirement.
Certainly, positioning hole also can be arranged to other number according to actual conditions.
A kind of preferred structure of positioning device noted earlier, on described solid of rotation one end face, some positioning holes are set, on described positioning device, also correspondence arranges a positioning hole, and through one of them positioning hole on positioning hole and the solid of rotation end face of positioning device, the relative position of positioning device and solid of rotation is fixed with pin.
As preferably, between described solid of rotation and major joint pipe, form cavity, cavity two ends seal with end casing, between left section and right section of cavity, spacer ring are set.After arranging like this, also respectively on the wall of solid of rotation with secondary spray line, main feed back pipe, secondary feed back pipe corresponding position perforate, and, open hole in the corresponding position of the secondary spray line of major joint Guan Shangyu, the main feed back pipe of major joint Guan Shangyu, the corresponding position of secondary feed back pipe respectively perforate make main feed back pipe, secondary feed back pipe be communicated with feed back chamber.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: can rotate by 360 deg, and can locate; Multi-path design, compact structure is simple, manufactures and installs all very convenient.
