Abstract
The utility model relates to an ultralow thin type hydraulic jack which comprises a cylinder body, a cylinder cap and a piston rod. A high pressure connector communicated with a cylinder body inner cavity is arranged at a side wall of the bottom of the cylinder body. The piston rod is in sealed arrangement in the cylinder body inner cavity in a sliding mode. The top portion of the piston rod extends out of the top portion of the cylinder body. The bottom of the piston rod is in sliding fit with a side of the cylinder body inner cavity. The ultralow thin type hydraulic jack is simple in structure, convenient to use and capable of satisfying the low requirement of lifting hydraulic pressure and the requirement of lifting in an ultralow and super-narrow space.
Description
Technical field
The utility model relates to a kind of jack, is a kind of ultralow slim hydraulic jack specifically, is widely used in power plant, Ship Building and Repairing, building, mining, steel plant, oil field etc.
Background technology
In the prior art, increase accurately and lifting in very narrow space, its closed height and maximum form primary factor, therefore need to adopt ultralow slim hydraulic jack.Be the disclosed single-action super-thin hydraulic jack of 02150959.X such as the patent No., the push rod that uses the more piece piston rod to consist of, carry out that hydraulic pressure increases and lifting, the compression area of such jack more piece piston rod reduces gradually, when lifting was stressed, inlet hydraulic required greatly to require high for the feed liquor under ultralow, the super narrow space in the cylinder body, usage condition requires high, and great majority can't satisfy operating needs.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model provides a kind of simple in structure, and is easy to use, can take into account the ultralow slim hydraulic jack of lifting requirement under less demanding and ultralow, the super narrow space of lifting hydraulic pressure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of ultralow slim hydraulic jack, comprise gray iron and piston rod, it is characterized in that: described cylinder base sidewall is provided with the high pressure connection that is communicated with inner chamber of cylinder block, piston rod packing is slided and is arranged at inner chamber of cylinder block, and piston rod part stretches out the cylinder body top.
Be dynamically connected through the sealing member sealed sliding between described piston rod and inner chamber of cylinder block sidewall.
Be provided with the stay-supported type displacement sensor of band signal data line between described piston rod top and the cylinder body bottom.
Described piston rod basal sliding cooperates the inner chamber of cylinder block side.
Compared with prior art, the utility model has the advantages that: high pressure connection is to the inner chamber of cylinder block feed liquor, fluid pressure acts on the piston rod bottom, piston rod is ejected cylinder body to be acted on and increases or the lifting object, the piston rod basal sliding cooperates the inner chamber of cylinder block side, bearing surface is large, can take into account lifting requirement under less demanding and ultralow, the super narrow space of lifting hydraulic pressure, is fit to the various super ends, the use of super narrow working space.
