Specific implementation mode
The application is described further in the following with reference to the drawings and specific embodiments, so that those skilled in the art can be with
It more fully understands the application and can be practiced, but illustrated embodiment is not as the restriction to the application.
As shown, this application provides a kind of automation jacking apparatus, the jacking apparatus includes supporting table 2, position
Lifting platform 1 in 2 upside of supporting table, passes through multiple lifting columns 3 between the supporting table 2 and the lifting platform 1
It is connected, the lower surface of the lifting platform 1 is provided with pulley 12, and the jacking apparatus further includes hydraulic cylinder 5, by described
The push rod 51 of the driving of hydraulic cylinder 5, the wedge block 4 driven by the push rod 51, the push rod 51 is in the hydraulic cylinder 5
It is moved along X-direction under driving, the one side far from the push rod 51 of the wedge block 4 is an inclined-plane 41 upward.
The lifting platform 1 has the first height and the second height, when the lifting platform 1 is located at the first height, the wedge shape
Block 4 does not have active force to the pulley 12, and when the lifting platform 1 is located at the second height, the pulley 12 is described
Wedge block 4 under the action of the upper surface of the wedge block 4 is slid into along the inclined-plane 41.The pulley 12 passes through one
12 mounting base 11 of pulley is mounted on the lower surface of the lifting platform 1.12 mounting base 11 of pulley in the Y-axis direction with institute
The distance for 1 lower surface of lifting platform stated is adjustable.It is additionally provided in 12 mounting base 11 of pulley for by the pulley
12 are locked in the locking device of the second height.The lifting column 3 includes what upper end was fixedly connected with 1 phase of lifting platform
The lower beam that upper boom, lower end are fixedly connected with 2 phase of supporting table, the lower end of the upper boom, which can slide up and down, to be arranged
In the lower beam.A slideway being arranged along X-direction is provided on the inclined-plane 41, when the wedge block 4 jacks
When the described pulley 12, the pulley 12 is slided along the slideway.The hydraulic cylinder 5 is fixedly mounted on the support
On platform 2.
A kind of automation jacking apparatus of the application has used the cooperation of wedge block 4 and pulley 12 to jack lifting platform 1, will
When lifting platform 1 maintains certain height, the weight of lifting platform 1 is fallen on wedge block 4, will not be caused stress, be prolonged to hydraulic press
The service life of hydraulic press is grown.In addition, the power being horizontally oriented that hydraulic press applies wedge block 4, it will be able to lifting platform 1
Play the role of jacking.
In this application, X-direction is left and right directions as shown in Figure 1, and Y-direction is upper and lower directions as shown in Figure 1.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the application, the protection model of the application
It encloses without being limited thereto.Those skilled in the art on the basis of the application made by equivalent substitute or transformation, in the application
