Abstract
The utility model relates to a hydraulic lifting apparatus, comprising: a support plate which is in contact with a workpiece and remains horizontal, liftable hydraulic columns which are vertical to and fixedly connected with the support plate, a fixed hydraulic cylinder which is matched with the liftable hydraulic columns, an independent hydraulic station which controls a plurality of liftable hydraulic columns simultaneously, a base which is fixedly connected with the fixed hydraulic cylinder, and lead screw lifts positioned on the base, wherein the number of the liftable hydraulic columns isat least 3 and the distance between adjacent liftable hydraulic columns remains equal; and the number of the lead screw lifts is at least 3 and the distance between adjacent lead screw lifts remainsequal. Compared with the prior art, the hydraulic lifting apparatus has the advantages of: lifting large objects; enhancing load range and stability thereof; stabilizing the hydraulic cylinder better;and facilitating the movement of the hydraulic lifting apparatus.
Description
Technical field
The utility model relates to a kind of device with predetermined lift lifting load, particularly a kind of hydraulic jacking equipment.
Background technology
Because jack is with less by the area of contact of top workpiece, there is defective in jack when jacking large-sized object or heavy duty.
Summary of the invention
The utility model designed a kind of can jacking large-sized object or heavily stressed hydraulic jacking equipment.
The technical solution of the utility model is as follows:
Hydraulic jacking equipment, comprise: the supporting plate that contacts and keep horizontality with workpiece, Liftable hydraulic post vertical with supporting plate and that captive joint with supporting plate, the immobile liquid pressure cylinder that matches with the Liftable hydraulic post, control the independent hydraulically controlled station of some Liftable hydraulic posts simultaneously, with the base that the immobile liquid pressure cylinder is captiveed joint, be positioned at the silk jacking in vain on the base; Above-mentioned Liftable hydraulic post quantity is at least 3, and the distance between the adjacent Liftable hydraulic post keeps equating; Above-mentioned leading screw jacking quantity is at least 3, and the distance between the adjacent leading screw jacking keeps equating.
Said fixing ram pot and base can achieve a fixed connection by four foot rests.
Above-mentioned base can be a grid.
As preferred version, also comprise: be positioned at the cardan wheel on the base, above-mentioned cardan wheel quantity is at least 3, and the distance between the adjacent cardan wheel keeps equating.
Working process of the present utility model is as follows:
Under no-load condition, can realize moving by cardan wheel;
During work, at first the leading screw jacking on the base is adjusted to and treated lifting workpiece below, both made supporting plate keep horizontality, cardan wheel is not carried;
Under the control at an independent hydraulically controlled station, all Liftable hydraulic posts rise simultaneously, and workpiece rises thereupon, after lifting puts in place, and the self-locking of Liftable hydraulic post;
During decline, at first open Liftable hydraulic post self-locking mechanism, under the control of unified Hydraulic Station, the Liftable hydraulic post descends, and resets until workpiece;
Discharge the leading screw jacking, rely on cardan wheel to land mobile then hydraulic jacking equipment.
The present invention has following advantage with respect to prior art:
(1) design of supporting plate can make this equipment jacking large-sized object;
(2) install in parallel of Liftable hydraulic post and synchronization lifting can improve load range and stability thereof greatly;
(3) can make ram pot more stable by four foot rest immobile liquid pressure cylinders and base;
(4) design of cardan wheel can make this hydraulic jacking equipment conveniently moving.
