Abstract
The invention relates to a hydraulic lifting device for machinery. A support cylinder is disposed at the bottom of a to-be-supported object. A support block is disposed between the to-be-supported object and the support cylinder. The support block is formed by integrating an upper half cone and a lower half cone. The upper half cone is embedded into the bottom of the to-be-supported object. The lower half cone extends into the top end of the support cylinder. The support cylinder includes an upper half cylinder and a lower half cylinder. The inner diameter of the lower half cylinder is smaller than the inner diameter of the upper half cylinder. A slider column and an I-shaped adjusting block are respectively slidably mounted in the lower half cylinder and the upper half cylinder. The top end of the I-shaped adjusting block is embedded into the bottom of the slider column. A seal ring is disposed between the upper half cylinder and the lower half cylinder. The bottom end of the lower half cylinder is communicated with a hydraulic oil injection system. The hydraulic lifting device is simple in structure, stable and reliable in adjusting and extremely high in practical value, the split structure is adopted, indirect lifting of the to-be-supported object is achieved through injection pressure of hydraulic oil, and large load can be borne by each structural point.
Description
Technical field
The present invention relates to a kind of machinery hydraulic lift.
Background technology
In known technical field, in machine manufacture processing, often need to treat the adjusting that processing object is carried out upright position, general on bench board or fixture, adopt manually, driving or directly the height of jacking fixture regulate, for general weight, can also deal with like this, when precisely regulating in the face of overweight or needs, just seem more difficult.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provide a kind of degree of regulation control ability good, can adapt to heavy weight machinery hydraulic lift.
The technical solution adopted for the present invention to solve the technical problems is: a kind of machinery hydraulic lift, comprise object to be supported, bottom at described object to be supported is provided with support tube, between described object to be supported and support tube, be provided with back-up block, described back-up block is connected as a single entity and is formed by upper semi-circle cone and lower half circle cone, and described upper semi-circle cone is embedded in the bottom of object to be supported, described lower half circle cone is inserted in the top of support tube, described support tube is divided into first cylinder and second two parts, and described second interior is all less than first interior all, in described second cylinder and second cylinder, be slidably fitted with respectively slide block post and I-shaped adjustment block, and the top of described I-shaped adjustment block is embedded in the bottom of slide block post, between described first cylinder and second cylinder, be provided with seal ring, described second bottom is connected with hydraulic oil injecting systems.
Further, as a kind of concrete embodiment, the present invention is provided with arc groove in the bottom of described I-shaped adjustment block.
The invention has the beneficial effects as follows: the present invention is simple in structure, adopt split type structure, by the injection pressure of hydraulic oil, indirectly treat support object and carry out jacking action, control process is solid and reliable, and each system point can bear larger load, has practical value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
In figure: 1. object to be supported, 2. support tube, 21. first cylinders, 22. second cylinders, 3. back-up block, 31. upper semi-circle cones, 32. lower half circle cones, 4. slide block post, 5. I-shaped adjustment block, 51. arc grooves, 6. seal ring.
