Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described in detail:
Such as Fig. 1, it is positioned at the start pin of automatic homing pilot operated valve device center, the most protruding cavity.Open
Leave certain gap about untie-sell, it is allowed to move around, promote cylindrical piston connection oil circuit, it is achieved draining purpose.Open
The front end plush copper of untie-sell is designed to half round saw dentation, just injects in the recess on para-position arresting disc top, when para-position arresting disc just
When turning (upper button), the zigzag plush copper inclined-plane of start pin front end makes start pin compress backward just, is i.e. just ensureing para-position arresting disc
When turning unrestricted, thus pull and smoothly complete on ensureing.When, after upper buckle, hydraulic tongs need to recess oil pipe, return to former
Come position.At this moment, solenoid directional control valve changes the oil circuit of hydraulic tongs, makes gear wheel invert, and para-position arresting disc inverts the most together.
When start pin plush copper sticks into the recess of para-position arresting disc, block mutually owing to para-position arresting disc is faced directly with start pin, then promote startup
Pin cylindrical piston in a side shifting, automatic homing control valve is forced to draw back, the oil leak hole connection on piston, makes hydraulic pressure
The oil supply system of pincers motor forms short circuit, has cut off power, and at this moment gear wheel opening is just consistent with hydraulic tongs opening, hydraulic tongs
Can exit smoothly and return.When shackle (gear wheel rotates counterclockwise), first turnback, i.e. sawtooth are adjusted in the direction of start pin
The inclined-plane of shape plush copper is towards rightabout.Contrary with upper button program, shackle can be completed.
Above in conjunction with accompanying drawing, embodiments of the invention are described, but the invention is not limited in above-mentioned concrete
Embodiment, above-mentioned detailed description of the invention is only schematic rather than restrictive, those of ordinary skill in the art
Under the enlightenment of the present invention, in the case of without departing from present inventive concept and scope of the claimed protection, it may also be made that a lot
Form, within these belong to the protection of the present invention.
