Abstract
The utility model discloses an improved hydraulic cylinder structure and belongs to the technical field of hydraulic machinery. A hydraulic cylinder product, in which the prior hydraulic cylinder structure is changed, is mainly composed of a cylinder barrel, a piston tube, a locating tube or column, a base and a sealing element so that the hydraulic cylinder is suitable for being installed and used in hydraulic machinery equipment with a lower load and a large stroke. The pressure active area required for a given load is calculated under the conditions such as load, pressure, etc., and the sizes of the locating tube or column inside the hydraulic cylinder body are designed to ensure that the active areas of a hydraulic piston and a piston tube end are matched with the pressure active area required for load performance. Compared with a regular hydraulic cylinder, the improved hydraulic cylinder structure has the advantages of reducing the oil quantity stored inside the cylinder body, decreasing the size of the a oil tank assorted with a hydraulic system, reducing flow rate of a hydraulic pump, reducing power configuration of an electric motor, reducing costs, saving energy, and improving the application range of the hydraulic cylinder. The utility model is particularly applied in the field of low-load, large-stroke hydraulic elevators, and has the characteristics of simple operation, energy conservation, novelty, practicality and feasibility.
Description
Technical field:
The utility model provides a kind of hydraulic cylinder structure that has improved, and belongs to the hydraulic machinery technical field.
Background technique:
Existing hydraulic cylinder structure is formed approved product by major parts such as cylinder barrel, piston, piston rod, sealing guide sleeves, is applied in the every profession and trade widely.But in the hydraulic machinery equipment of little load, big stroke, use and obvious defects occurred, its cylinder barrel oil pocket is big, piston rod is thick, make the configurations such as fuel tank, flow, oil hydraulic pump, motor of hydraulic system big, power consumption is high, the manufacture cost height, the result has limited application and the development at the hydraulic machinery equipment of low load, big stroke.
Summary of the invention:
The utility model provides a kind of hydraulic cylinder structure that has improved, and belongs to the hydraulic machinery technical field.Product by cylinder barrel, piston tube, positioning pipe or location are lived, major parts such as base, Sealing are formed is applicable to low load, the hydraulic machinery equipment of stroke is installed and used greatly.
Technical solution of the present utility model is as follows: be center fixation connection positioning pipe or the locating column at hydraulic cylinder base, fixedly connected hydraulic cylinder on the hydraulic cylinder base, between hydraulic cylinder and positioning pipe or the locating column piston tube is installed, the hydraulic pressure assembling has the hydraulic piston of sealing function between hydraulic cylinder and the hydraulic piston pipe, be equipped with Sealing between positioning pipe or locating column and the hydraulic piston pipe, between the side of the lower end of positioning pipe or bottom and cylinder barrel or base, fixedly connected oil guide pipe, the position of the corresponding oil guide pipe of piston tube is provided with U type mouth, and hydraulic oil enters in the oil hydraulic cylinder body cavity by oil inlet and outlet and promotes hydraulic piston, hydraulic piston pipe lifting operation.
The present invention compares its good effect with existing like product and is: changed existing hydraulic cylinder structure, by cylinder barrel, piston tube, positioning pipe or location live, major parts such as base, Sealing form the oil hydraulic cylinder product, make that oil hydraulic cylinder is applicable to low load, the hydraulic machinery equipment of stroke is installed and used greatly.Pass through load, conditions such as pressure are calculated and are set the pressure effective area that load needs, the positioning pipe in the design hydraulic cylinder or the size of locating column, make hydraulic piston, the pressure effective area coupling that the useful area of piston pipe end and load operation need, result and common oil hydraulic cylinder comparison, trapped fuel amount in the body reduces, the supporting fuel tank of hydraulic system is reduced, the oil hydraulic pump flow reduces, the power of motor configuration reduces, reduced cost, saved energy, improved the application area of oil hydraulic cylinder, particularly in low load, the hudraulic lift field of big stroke is used simply energy-conservation, Nover practical has real feasibility.
Description of drawings:
Fig. 1 is a structure principle chart of the present utility model.
1-hydraulic cylinder base, 2-positioning pipe or locating column, 3-hydraulic cylinder, 4-piston tube, 5-piston, 6-Sealing, 7-Sealing, 8-Sealing, 9-oil inlet and outlet, 10-positioning pipe tube chamber, 11-oil guide pipe.
Embodiment:
Shown in figure, center fixation at hydraulic cylinder base 1 connects positioning pipe 2, fixedly connected hydraulic cylinder 3 on the hydraulic cylinder base 1, piston tube 4 is installed between hydraulic cylinder 3 and the positioning pipe 2, the hydraulic pressure assembling has the hydraulic piston 5 of sealing function between hydraulic cylinder 3 and the piston tube 4, be equipped with Sealing 6 between positioning pipe 2 and the hydraulic piston pipe 4,7,8, between the downside tube chamber 10 of positioning pipe 2 and cylinder barrel 3, fixedly connected oil guide pipe 11, the position of piston tube 4 corresponding oil guide pipes 11 is provided with U type mouth, and hydraulic oil enters by oil inlet and outlet 9 and promotes hydraulic piston 5 in the oil hydraulic cylinder body cavity, hydraulic piston pipe 4 liftings operation.
