Abstract
The invention discloses a hydraulic device. The hydraulic device comprises a base, a hydraulic cylinder, a spring, a hydraulic cover, a piston and a piston rod which are respectively fixedly connected, and is also provided with a seal ring. The hydraulic device is applicable to brakes, hydraulic positioning and the like, and has the characteristics of simple structure, small size, stability, reliability, convenient maintenance and the like.
Description
Technical field
The present invention relates to a kind of hydraulic pressure installation.
Background technique
The braking force source of break mainly adopts pusher to realize at present, pusher thrust requires larger, its pusher volume is larger, be not suitable for applying in the space of limitation, so progressively adopt hydraulic pressure installation to substitute pusher, to break, provide power source, it is large that its hydraulic pressure installation has Driving force, the characteristics such as power source is stable, simple in structure, and volume is little.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hydraulic pressure installation, its have simple in structure, volume is little, the characteristics such as reliable and stable, easy to maintenance.
For solving the problems of the technologies described above, a kind of hydraulic pressure installation of the present invention comprises base, and base is provided with positioning hole and oil inlet and outlet, and positioning hole is connected with break brake arm or pedestal, between base and oil hydraulic cylinder, establishes seal ring, and is bolted connection; Be provided with seal ring between oil hydraulic cylinder inwall and piston, piston is fixedly connected with by set screw nut with piston rod, prevents that piston rod is loosening; Hydraulic cover is fixedly connected with oil hydraulic cylinder by bolt, is provided with a spring between hydraulic cover and piston, between hydraulic cover and piston rod, is provided with seal ring, and piston rod fixedly screw mandrel is connected with break brake arm or pedestal.
As a modification of the present invention, establish built-in spring structure at hydraulic pressure installation, under the effect of spring force, can make piston rod automatically reset.
As a modification of the present invention, only on base, establish an oil inlet and outlet in hydraulic pressure installation.
The accompanying drawing explanation
Fig. 1 is the structural representation that partly cuts open of the present invention.
Fig. 2 is the left surface structural representation of Fig. 1 of the present invention.
Embodiment
As shown in Figure 1, the present invention includes base 2, base 2 is provided with positioning hole 1 and oil inlet and outlet 2, positioning hole 1 is connected with brake arm or the pedestal of break, piston rod 8 fixedly screw mandrel is connected with brake arm or the pedestal of break, base 2, oil hydraulic cylinder 9, spring 10, hydraulic cover 11, piston 5, piston rod 8 are fixedly connected with respectively, and are provided with seal ring 4,6,13; When the hydraulic station energising, hydraulic oil enters oil hydraulic cylinder 9 by oil inlet and outlet 3, promotes piston 5 and moves axially, and drive piston rod 8 and move axially, thereby the brake arm of drive break inwardly relatively moves, and Brake drum is implemented to braking, and equipment quits work.
When hydraulic station cuts off the power supply, piston 5, under the effect of spring 10 elastic force, resets piston 5, and hydraulic oil flows back to hydraulic station from oil inlet and outlet 3, drives piston rod 8 and resets, and brake arm and Brake drum are broken away from, and equipment can work.
The left surface configuration diagram that Fig. 2 is Fig. 1.
