Abstract
The invention relates to an elevator safety braking device, in particular to a hydraulic buffer. The buffer comprises a fixing base plate, the bottom of the fixing base plate is provided with a support column, the fixing base plate is provided with a hydraulic column, the top of the hydraulic column is provided with a support body in a retractable mode, and the fixing base plate is further provided with a drive motor. According to the hydraulic buffer, the fixing base plate is arranged on a buffer body, the bottom of the fixing base plate is provided with the support column, the fixing base plate is provided with the hydraulic column which is driven by the drive motor, the buffer action is achieved through the retractable support body arranged on the hydraulic column, and compared with a simple buffer of a hydraulic cylinder, the support force can be precisely controlled and the buffer effect can be regulated by regulating the revolving speed of the motor on the shortening forming condition.
Description
Technical field
The present invention relates to a kind of elevator safety brake device, especially a kind of hydraulic cushion phase.
Background technology
Hydraulic bjuffer is mainly realized buffering and the two kinds of functions that reset, in the time that the object of high-speed cruising impacts buffer suddenly,By the effect of its throttling and accumulation of energy, control object and slow down, stop object moving gradually, rear realization resets.
Current hydraulic bjuffer, as China Patent No. ZL01207454.3 discloses a kind of oil buffer,ZL02281860.X discloses a kind of hydraulic buffer of elevator, is divided into two cavitys by the plunger base of plunger end opening, two cavitysThrottle orifice by plunger base is communicated with. Because of the cavity of plunger upper part mixing air (even if check valve is set, in its plunger not yetThe evitable air that exists), in buffering course, the oil in the oil pocket of bottom presses in plunger by throttle orifice, enters in plungerOil and already present air produce air-fuel mixture phenomenon, produce high pressure in moment, impact comparatively obviously, shock-absorbing capacity is unstable,Shock-absorbing capacity poor repeatability, service life is low; In addition, existing hydraulic bjuffer height is higher, and like this, it occupies largerSpace.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides one highly low, enabling capabilities is strong, the hydraulic pressure of good buffer effect is slowRush device.
Hydraulic bjuffer of the present invention comprises a fixed base plate, is provided with a support column in the bottom of described fixed base plate, in instituteThe fixed base plate of stating is provided with a hydraulic column, and at the top of described hydraulic column, telescopically is provided with a supporter, described consolidatingDetermine to be also provided with on base plate a drive motors.
Preferably, described drive motors is AC induction motor.
Preferably, between described drive motors and hydraulic column for tooth bar is connected.
Because hydraulic bjuffer of the present invention is provided with a fixed base plate on body, be provided with one in the bottom of fixed base plateIndividual support column, is provided with a hydraulic column on fixed base plate, hydraulic column is driven by a drive motors, by stretching on hydraulic columnContracting supporter completes cushioning effect, and the buffer of the simple hydraulic cylinder of comparing can be by regulating in the situation that shortening formationThe rotating speed of motor is accurately controlled support force and is regulated buffering effect.
Brief description of the drawings
Fig. 1 is perspective view of the present invention;
Fig. 2 is the perspective view at another visual angle of the present invention.
Detailed description of the invention
As Figure 1-Figure 2, hydraulic bjuffer 1 of the present invention comprises a fixed base plate 2, at described fixed base plate 2Bottom is provided with a support column 3, is provided with a hydraulic column 4 on described fixed base plate 2, can stretch at the top of described hydraulic column 4Be provided with a supporter 5 to contracting, on described fixed base plate, be also provided with a drive motors 6.
In the present embodiment, described drive motors 6 is AC induction motor.
In the present embodiment, between described drive motors 6 and hydraulic column for tooth bar is connected.
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, everyly utilize thisThe equivalent structure that bright description and accompanying drawing content are done or the conversion of equivalent flow process, or be directly or indirectly used in other relevant technologyField, is all in like manner included in scope of patent protection of the present invention.
