Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The described electric hydaulic of the utility model device that warps, when push-rod piston rose to top or lowermost end, it is big that the motor resistance becomes, and it is big that electric current becomes, and makes over temperature protection system cut off the electricity supply automatically, motor stall, thereby protection motor and inner member in-use performance; Lifting/the falling head of the outboard engine of the utility model control has certain qualification, thereby safe; Has overload self-protection function simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Cutaway view when accompanying drawing 1 warps first state of device for the electric hydaulic of the utility model;
Cutaway view when accompanying drawing 2 warps second state of device for the electric hydaulic of the utility model;
Wherein: 1, cylinder; 2, free piston; 3, reservoir; 4, gear type pump; 5, cylinder body; 6, main valve; 7, shuttle piston; 8, motor; 9, piston rod; 10, push-rod piston.
The specific embodiment
Like accompanying drawing 1, the described a kind of electric hydaulic of the utility model shown in 2 device that warps, comprise cylinder 1, free piston 2, reservoir 3, gear type pump 4, cylinder body 5, main valve 6, shuttle piston 7, motor 8, piston rod 9, push-rod piston 10; Said reservoir 3, main valve 6 are separately positioned on cylinder body 5 inside; Said gear type pump 4 is arranged in the reservoir 3; The output shaft of said motor 8 links to each other with gear type pump 4; Said free piston 2 is arranged on the inside of cylinder 1; One end of said piston rod 9 is arranged on the push-rod piston 10, and the other end stretches out cylinder 1 and links to each other with outboard engine; Said free piston 2 is arranged on the below of push-rod piston 10; The top of the internal cavity of said cylinder 1, bottom all are connected through the pipeline of pipeline with the two ends of main valve 6; Said shuttle piston 7 is arranged between the pipeline at two ends of main valve; Said gear type pump 4 is connected with the pipeline at the two ends of main valve 6 respectively through pipeline; When control motor 8 anticlockwise motions, motor 8 driven gear pumps 4 make flow of pressurized flow towards main valve 6, when flow of pressurized arrives main valve 6, the shuttle piston 7 of main valve 6 are slided to the right, open fluid pipe and make flow of pressurized flow into the bottom of cylinder 1; Along with the bottom of flow of pressurized entering cylinder 1, it will upwards promote free piston 2, and free piston 2 drives push-rod pistons 10 and rises, and causes that then piston rod 9 moves up, and make outboard motor tilt to rise; Flow of pressurized in said cylinder 1 top flows through pipeline, is back to main valve 6, arrives gear type pump 4 then; When the rotation of motor 8 clockwise directions, motor 8 driven gear pumps 4 make flow of pressurized flow towards main valve 6; When flow of pressurized arrived main valve 6, it can cause that the shuttle piston 7 of main valve 6 is moved to the left, and opened fluid pipe and made flow of pressurized flow into cylinder 1 upper portion; When flow of pressurized gets into the top of cylinder 1, then can promote push-rod piston 10 downwards, then piston rod 9 can be along with push-rod piston 10 moves down; Reduce outboard motor, the pipeline of flowing through of the flow of pressurized in cylinder 1 bottom is back to main valve 6; Arrive gear type pump 4 then, arrive reservoir 3 at last.
The described electric hydaulic of the utility model device that warps has following characteristics:
1, the electric hydaulic device stop condition that warps
