Abstract
The invention discloses a hydraulic jack. The hydraulic jack is mainly composed of a hydraulic pump, a piston cylinder and an oil cylinder, wherein the hydraulic pump communicates with the piston cylinder through a pipeline A; the hydraulic pump communicates with the oil cylinder through a pipeline B; the piston cylinder communicates with the oil cylinder through a pipeline C; the pipeline A and the pipeline B are each provided with an oil sealing cavity, small balls are arranged in the oil sealing cavities, and the diameter of the small balls is larger than that of the pipeline A or the pipeline B; the pipeline C is provided with an oil release valve. Due to the design of the oil sealing cavities and the small balls, the hydraulic pump can only pump oil from the oil cylinder and only push the oil into the piston cylinder in work, so that the oil is continuously conveyed into the piston cylinder from the oil cylinder. After a hoisting task is completed, the oil release valve is opened, and then the oil can be released into the oil cylinder. Operation is simple, convenient, safe and reliable.
Description
Technical field
The present invention relates to a kind of jack.
Background technology
Jack plays very important effect in modern industry is applied, it can support the sizable object of weight, but due to some special circumstances, jack needs to support weight longer a period of time, and some special jack can complete such task, but due to support weight for a long time, piston extension spring is shaped, after withdrawing under weight, piston substantially cannot return, cause that jack is scrapped.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hydraulic jack.
In order to solve above-mentioned technical problem, the invention provides a kind of hydraulic jack, mainly it is made up of hydraulic pump, piston cylinder and oil cylinder, it is connected by pipeline A between hydraulic pump with piston cylinder, being connected by pipeline B between hydraulic pump with oil cylinder, be connected by pipeline C between piston cylinder with oil cylinder, described pipeline A and pipeline B is respectively equipped with oil sealing chamber, oil sealing intracavity is provided with bead, and the small ball's diameter is more than pipeline A(4) or the diameter of pipeline B.
As a further improvement on the present invention, described pipeline C is provided with gate gurgle valve.
Adopt said structure, it has the beneficial effects that: the present invention adopts the design of oil sealing chamber and bead, make hydraulic pump can only pump in oil cylinder and can only be pushed in piston cylinder by oil in the course of the work, thus oil is continuously sent in piston cylinder in oil cylinder, after completing lifting task, open gate gurgle valve and oil can be let out in oil return cylinder, easy and simple to handle, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic jack of the present invention.
In figure: 1-hydraulic pump, 2-piston cylinder, 3-oil cylinder, 4-pipeline A, 5-pipeline B, 6-pipeline C, 7-oil sealing chamber, 8-bead, 9-gate gurgle valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1, a kind of hydraulic jack, mainly it is made up of hydraulic pump 1, piston cylinder 2 and oil cylinder 3, it is connected by pipeline A4 between hydraulic pump 1 with piston cylinder 2, is connected by pipeline B5 between hydraulic pump 1 with oil cylinder 3, be connected by pipeline C6 between piston cylinder 2 with oil cylinder 3, described pipeline A4 and pipeline B5 is respectively equipped with oil sealing chamber 7, being provided with bead 8 in oil sealing chamber 7, bead 8 diameter diameter more than pipeline A4 or pipeline B5, described pipeline C6 is provided with gate gurgle valve 9.
During use, first gate gurgle valve 9 is locked, operation hydraulic pump is pumped and send oil, during oil pumping, in the oil sealing chamber 7 of pipeline B, bead 8 rises with hydraulic oil, open accent, hydraulic oil is made to enter in hydraulic pump 1, bead 8 in the oil sealing chamber 7 of pipeline A props up accent simultaneously, prevent leakage of oil, otherwise, during force feed, hydraulic oil can only enter piston cylinder 2 from hydraulic pump 1, constantly 1 pressure is taken out through hydraulic pump, oil constantly arrives piston cylinder 2 from oil cylinder 3 through pipeline B and pipeline A, so that piston rises, jack-up weight, after completing lifting task, open gate gurgle valve 9, make oil let out in piston cylinder 2 to be back in oil cylinder 3.
The similar hydraulic jack designed by technical characteristic of any employing and the present invention will fall within protection scope of the present invention.
