Put.
Background technology
Executor is a kind of driving means providing straight line or rotary motion, and it utilizes certain drive energy and controls letter at certain
Working under number, it is divided into electronic, pneumatic according to the energy form used and surges or other energy executor.The most electronic hold
Row utensil takes the advantages such as convenient easily, transmission fast, the long distance of signal transmission of signal speed of the energy, and its degree of accuracy, spirit
Sensitivity is of a relatively high, coordinates with other motorized adjustment instrument conveniently, easily operates；Anti-inclined ability is preferable, the moment that exported or
Thrust substantially constant, can accomplish preferably to overcome the out-of-balance force of medium, it is ensured that reach the accurate control of related process parameters,
Its control accuracy wants height compared to the controller of other form.
General YE all adds the mode of manually performing, it is ensured that the seriality that under blackout condition, executor uses, at electricity
Under dynamic state, worm drive worm gear drives output shaft rotation, when there is the situation needing manually regulation, rotates handwheel and controls
Worm screw is to realize Non-follow control output shaft.If fixing, with worm screw, the mode being connected according to traditional handwheel to install handwheel, running
During handwheel quickly can rotate along with worm screw, the personal safety to operator threatens.
Summary of the invention
The present invention solves that technical problem present in known technology provides a kind of simple and reasonable, easy to use, safe
The YE manual safety transmitting device that property is high.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of YE is manual
Safe transmission device, including casing, is provided with worm component in casing, and one end of the worm screw of described worm component passes case
The end face of body；Also including the end cap being set on worm screw, the outer face of described end cap and casing is fixed；Also include through end cap
And axially displaceable short axle, short axle is provided with strong magnet, in casing, is installed with the Hall matched with strong magnet
Sensor, is provided with detachable and that short axle can carry out top pressure closure, is provided with auxiliary short in casing in the outside of end cap
The spring that axle ejects.
Advantages of the present invention and good effect be: the present invention controls moving axially of short axle by closure and spring, thus changes
The relative position of strong magnet and Hall element；Closure is arranged on end cap, and strong magnet realizes electronic with Hall element Guan Bi
Control；Pulling down closure, short axle ejects, and strong magnet departs from Hall element, can install manual components at worm end, real
Existing Non-follow control.Manually divide clear with electronic two kinds of executive modes, improve executor's safety in utilization, be substantially reduced operation
During accident rate.
Preferably: described end cap is "convex" shaped, described closure uses with "convex" shaped top and threadeds.
Preferably: described short axle passes vertically through "convex" shaped edge, described closure is the hat-shaped structure being provided with limit eaves, institute
State limit eaves to be correspondingly arranged with short axle.
Preferably: described spring housing is located at the tail end of short axle, the axial location of described spring tail end is fixed, head end and short axle
Position relatively is fixed.
Preferably: in the junction of end cap with casing, " O " shape sealing ring is set.

Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example and describe in detail as follows:
Seeing Fig. 1, the present invention includes casing 2, is provided with worm component 10 in casing 2, described worm component 10
One end of worm screw is through the end face of casing 2；Also include the end cap 7 being set on worm screw, described end cap 7 by screw 8 with
The outer face of casing 2 is fixed；Also include through end cap 7 and axially displaceable short axle 6, short axle 6 is provided with strong
Magnet 4, is installed with the Hall element 3 matched with strong magnet 4 in casing 2, and being provided with in the outside of end cap 7 can
Dismantling and can carry out short axle 6 closure 11 of top pressure, see Fig. 2, under motoring condition, worm screw external part is covered in envelope
In stifled 11, in casing 2, it is provided with the spring 5 assisting short axle 6 to eject.
In the present embodiment, described end cap 7 outer face is "convex" shaped, and described closure 11 uses with "convex" shaped top
Threaded；Described short axle 6 passes vertically through "convex" shaped one side portion, and described closure 11 is that the hat with limit eaves is tied
Structure, described limit eaves is correspondingly arranged with short axle 6.
Seeing Fig. 1 and Fig. 2, described spring 5 is set in the tail end of short axle 6, the axial location of described spring 5 tail end fixes,
Head end is fixed with the relative position of short axle 6, and described strong magnet 4 is positioned on the left of spring 5.
The junction of end cap 7 with casing 2 is provided with " O " shape sealing ring 9, prevents leakage of oil.
The use process of the present invention is:
Seeing Fig. 2, under electric control state, closure 11 rotation is tightened in fixing end cap 7 outer face, now blocks 11
Limit eaves withstand short axle 6 to casing 2 internal motion, spring 5 end-position is fixed, head end moves inward jointly with short axle 6,
Making spring 5 be in compressive state, the strong magnet 4 on short axle 6 coordinates with Hall element 3, it is achieved the electronic control of executor
System.
Seeing Fig. 1, under Non-follow control state, pull down closure 11, the distress resolves of short axle 6 end, at the work of spring 5
Under with, short axle 6 flicks naturally, makes strong magnet 4 disengage with Hall element 3, and Electronic control stops.Pacify at worm end
Dress handle 1, it is achieved the Non-follow control of executor.
The structure of this kind of YE can ensure that safety during manual operation, cannot install when not unloading closure 11
Manual components, it is impossible to realize manual operation, cannot realize electric operating, manually when unloading closure 11 and being operated manually
Electronic two kinds of executive modes divide clear, without potential safety hazard, the invention provides a kind of YE manual safety transmission dress
Put.
