Abstract
The utility model relates to a float balance oil-way using hydraulic pressure on spreading out board in spreading machine, comprising a stander(1) and two adjusting arms(7) which are fixed with the spreading out board; two oil cylinders(2) and(5) are respectively arranged between the stander(1) and the two adjusting arms(7), and the two oil cylinders(2) and(5) are connected in parallel, thus the two oil cylinders(2) and(5) share one fuel outlet. The balance oil-way using hydraulic pressure disclosed in the utility model is simple in structure and convenient in operation, favoring for immediately fitting for the change of transverse slope of spreading out board.
Description
The utility model relates to the hydraulic floating balance oil circuit of spreading plate in a kind of paver.
A kind of paver that China Patent No. 99115835.0 grades propose, lower plane and the ground for keeping V-type spreading plate scraping mechanism wherein mentioned keep opposing parallel or angled, need to extend forward by the spreading plate both sides, spreading plate is fixed together with the adjustment arm, adjust between arm front end and the frame regulating mechanism is arranged, the adjustment of this mechanism realizes by leading screw or by oil cylinder, but this regulating mechanism is independent regulation separately, change when being the spreading plate lateral inclination when the spreading plate horizontal wall inscription like this, the regulating mechanism of adjusting the arm front end can not adapt to the variation of spreading plate in time, and the result is easy to generate following defective: 1, the spreading plate horizontal wall inscription can't be regulated on request; 2, adjust arm and very easily twist damage; 3, complex structure, operation inconvenience.
The purpose of this utility model provides the hydraulic floating balance oil circuit of spreading plate in a kind of paver, and it can in time automatically adapt to the variation of the horizontal wall inscription of spreading plate, and have simple and reliable for structure, the advantage that cost is low.
The purpose of this utility model is achieved in that between spreading plate both sides adjustment arm front end and frame and respectively is provided with an oil cylinder that for being connected in parallel, promptly two oil cylinders are owned an oil inlet and outlet together between two oil cylinders.Like this, when the height of need adjustment adjustment arm front end, when promptly adjusting the thickness of paving layer, the stroke of adjusting two oil cylinders by the oil mass of regulating oil inlet and outlet just can.When the spreading plate horizontal wall inscription changed, both sides were adjusted between the arm front end and are certainly led to height difference, and according to the hydro-cushion principle, this height difference can be come automatic leveling by its oil circuit in parallel by two oil cylinders.
This oil cylinder can be two-way cylinder, adopts between two oil cylinders to be connected in parallel, and wherein big chamber communicates with big chamber, and loculus communicates with loculus.
Two oil cylinders also can be one-way cylinder, and its parallel form is to be linked to each other by oil pipe between the pressure chamber.
The position of this oil cylinder is being adjusted between arm and the frame, can be that the upper end links to each other with the adjustment arm, and the lower end links to each other with frame.
The position of this oil cylinder is being adjusted between arm and the frame, can be that the upper end links to each other with frame, and the lower end links to each other with the adjustment arm.
The hydraulic floating balance oil circuit of spreading plate in the utility model paver has only several parts to form, and is simple in structure, with low cost.Because of its two oil cylinder for being connected in parallel, when the spreading plate horizontal wall inscription changed, the height difference that produces between the arm was adjusted in both sides, can make two oil cylinders in parallel in time automatically adapt to the variation of horizontal wall inscription.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
Fig. 1 is the schematic representation of the hydraulic floating balance oil circuit of spreading plate in the basis a kind of paver that the utility model proposes.
Fig. 2 is the schematic representation of the another kind of hydraulic floating balance oil circuit of spreading plate in the basis a kind of paver that the utility model proposes.
As shown in Figure 1, the hydraulic floating balance oil circuit of spreading plate has a frame (1) in the utility model paver, and there are two two-way cylinders (2) and (5) in the below of this frame (1), and the other end of oil cylinder (2) and (5) links to each other with adjustment arm (7).The big chamber of two oil cylinders (2) and (5) communicates by oil pipe (3) with big chamber, and loculus communicates by oil pipe (4) with loculus, and oil cylinder (2) and (5) are owned an oil inlet and outlet together, and link to each other with valve (6).When the horizontal wall inscription of spreading plate changes, produce height difference between the adjustment arm (7) of both sides, produce pressure difference and the variation of leveling adaptation horizontal wall inscription automatically by oil cylinder (2) and (5) that link to each other with adjustment arm (7).
Second embodiment of the present utility model has been shown among Fig. 2, and outside removing oil cylinder and the oil pipe that links to each other with oil inlet and outlet being different from first embodiment, other structure of this hydro-cushion oil circuit all is identical.Oil cylinder in this embodiment (2) and (5) are one-way cylinder, are linked to each other by oil pipe (3) between the pressure chamber of oil cylinder (2) and oil cylinder (5).This embodiment can automatically adapt to the variation of spreading plate horizontal wall inscription and simple in structure, easy to operate.
