Abstract
The utility model provides a kind of MC multi-cylinder circular cone hydraulic protection system, comprise a plurality of oil hydraulic cylinders that are cascaded, safety valve, accumulator, solenoid directional control valve, described oil hydraulic cylinder series connection accumulator, it is characterized in that described solenoid directional control valve series connection hydraulic lock connects in parallelly with oil hydraulic cylinder after relief valve again, then connect with accumulator and pressure transducer; A safety valve of two chamber serial connections of each oil hydraulic cylinder.During overload, by safety valve and accumulator, played a protective role, safety valve is superimposed upon on oil cylinder simultaneously, and oil circuit is shorter, and the reaction time is faster.
Description
Technical field
The utility model relates to a kind of hydraulic pressure installation, relates in particular to the hydraulic system of a kind of pressurize locking and overload protection, especially overload protection function good stability.
Background technique
At present, known pressurize locking and overload protection hydraulic system only realize by accumulator, during overload pressure surge larger, the frequent overload protection life-span of accumulator can shorten greatly, can increase the cost of operation maintenance.
Summary of the invention
Large problem and the short problem of accumulator life-span of frequently transshipping of pressure surge while transshipping for overcoming oil hydraulic cylinder; the utility model provides a kind of multi-cylinder circular cone hydraulic protection system; the main safety valve that adopts is realized overload protection, realizes pressurize locking with an accumulator simultaneously.
The utility model is achieved like this.A kind of multi-cylinder circular cone hydraulic protection system, comprise a plurality of oil hydraulic cylinders that are cascaded, safety valve, accumulator, solenoid directional control valve, described oil hydraulic cylinder series connection accumulator, it is characterized in that described solenoid directional control valve series connection hydraulic lock connects in parallelly with oil hydraulic cylinder after relief valve again, then connect with accumulator and pressure transducer; A safety valve of two chamber serial connections of each oil hydraulic cylinder.
Technique effect of the present utility model is: a plurality of oil hydraulic cylinders are serially connected; first to accumulator, inflate; oil-filled to accumulator by solenoid valve again; thereby make oil cylinder that a constant coupling mechanism force is provided to external world all the time; by accumulator and hydraulic lock, realize pressurize; signal by pressure transducer goes automatically to realize automatic compensation function; a safety valve of two chamber serial connections of each oil hydraulic cylinder; during overload, by safety valve and accumulator, played a protective role simultaneously; safety valve is superimposed upon on oil cylinder; oil circuit is shorter, and the reaction time is faster.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is oil hydraulic cylinder component diagram of the present utility model.
1. safety valves in the drawings; 2. oil hydraulic cylinder; 3. accumulator; 4. pressure transducer; 5. hydraulic lock; 6. relief valve; 7. solenoid directional control valve; 8. valve piece.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of MC multi-cylinder circular cone hydraulic protection system, comprise a plurality of oil hydraulic cylinders that are cascaded 2, safety valve 1, accumulator 3, solenoid directional control valve 7, described oil hydraulic cylinder 2 series connection accumulators 3, it is characterized in that described solenoid directional control valve 7 series connection hydraulic lock 5 connect in parallelly with oil hydraulic cylinder 2 after relief valve 6 again, then connect with accumulator 3 and pressure transducer 4; A safety valve 1 of two chamber serial connections of each oil hydraulic cylinder 2.
As shown in Figure 2, safety valve 3 is contained on valve piece 2, and valve piece 2 is added under the flange of oil inlet and outlet of oil hydraulic cylinder 1.
In Fig. 1, by solenoid directional control valve 7 commutations, change oil hydraulic cylinder 2 direction of action; the input pressure of relief valve 6 restriction oil hydraulic cylinder 6 rod chambers; hydraulic lock 5 is pinned the pressure oil of accumulator 3 and oil hydraulic cylinder 2 rod chambers; pressure transducer 4 is used for controlling the automatic repairing of accumulator 3; accumulator 3 provides constant pressure to oil hydraulic cylinder 2 rod chambers; oil hydraulic cylinder 2 provides constant stretching coupling mechanism force to the external world, and safety valve 1 is used for realizing overload protection.
