Description
Technical field
The utility model relates to a kind of reverse direction actuation positioning hydraulic cylinders with no pressure, belongs to oil hydraulic cylinder apparatus field.
Background technique
Its main drive of machinery numerous at present source is realized by oil hydraulic cylinder, current hydraulic cylinder works mainly relies on oil hydraulic cylinder two hydraulic fluid ports to be connected with high pressure oil pump, enter or eject from different hydraulic fluid port the flexible rod realizing oil hydraulic cylinder by hydraulic oil to stretch out, retraction or keep, therefore no matter oil hydraulic cylinder is stretching out or bouncing back and all needing to be driven by high pressure liquid force feed of flexible rod in running, thus cause larger energy consumption, simultaneously, when the reason such as oil hydraulic pump and oil supply system failure cannot effectively to oil hydraulic cylinder fuel feeding time, the flexible rod difficulty that cannot effectively bounce back or bounce back then can be caused larger, thus cause overhaul of the equipments and maintenance difficulties increase, therefore need exploitation one to meet and reduce oil hydraulic cylinder energy consumption, can be bounced back voluntarily again the novel hydraulic cylinder of flexible rod under driving without exterior power.
Model utility content
For the deficiency that prior art exists, the utility model provides a kind of reverse direction actuation positioning hydraulic cylinders with no pressure, this new structure is simple, reasonable in design, reset operation can be reclaimed without outside retraction for realizing piston rod under kinetic pressure voluntarily at oil hydraulic cylinder, thus contribute to reducing hydraulic system energy consumption on the one hand, also contribute to after hydraulic pipe line etc. breaks down, realize oil hydraulic cylinder retraction on the other hand and reset, be convenient to plant maintenance and maintenance.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of reverse direction actuation positioning hydraulic cylinders with no pressure, comprise cylinder body, piston, flexible rod, positioning block, master reset spring and spring-assisted reduction, piston is positioned at cylinder body and is slidably connected with cylinder body, flexible rod end is connected with piston, front end is positioned at outside cylinder body, and cylinder body and flexible rod junction surface place establish at least one circle seal ring, flexible rod is positioned at cylinder interior and divides outer surface to establish connecting thread, and be connected with positioning block by connecting thread, positioning block is looped around outside flexible rod, and coaxially distribute with flexible rod, master reset spring housing on the piston rod, its one end is arranged on positioning block, the other end and cylinder body front inner surface offset, spring-assisted reduction at least two, and be distributed on positioning block around flexible rod, and another and cylinder body front inner surface offsets.
Further, another uniform oil-through hole on described positioning block, and positioning block and inboard wall of cylinder block spacing are not less than 1 millimeter.
Further, another uniform at least 4 slide blocks on described positioning block, its slide block and inboard wall of cylinder block are slidably connected.
This new structure is simple, reasonable in design, reset operation can be reclaimed without outside retraction for realizing piston rod under kinetic pressure voluntarily at oil hydraulic cylinder, thus contribute to reducing hydraulic system energy consumption on the one hand, also contribute to after hydraulic pipe line etc. breaks down, realize oil hydraulic cylinder retraction on the other hand to reset, be convenient to plant maintenance and maintenance.
