Above-mentioned a kind of powershift mechanism for electric actuator, comprises handwheel, manual shaft and body; Wherein, the top of described body is provided with limit switch, substrate and motor, and described motor is positioned on substrate; The inside of described body is from being disposed with Compress Spring, guide rod, cylindrical compression spring, positioning bead, bevel gear near one end of handwheel to the one end away from handwheel and exporting screw mandrel, described output screw mandrel is fixed on body, described substrate is secured by bolts in the upper surface of body, described motor is connected with output screw mandrel by gear, and described handwheel manually axle is connected with bevel gear.
In said mechanism, described handwheel is provided with handle.
In said mechanism, described limit switch is positioned at bodies top and one end of close handwheel.
In said mechanism, described motor is positioned at bodies top and away from one end of handwheel.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of powershift mechanism for electric actuator, operate under can being directly switch to the drive of armrest power under having possessed the state driving final controlling element work at electric power, and when needing to be switched to motoring condition under manual mode, switching can be completed instantaneously, thus possessed convenience, fast, practical, Safety performance is high, high efficiency, reduce the advantages such as cost of labor, and avoid the damage causing electric actuator, finally reach and increase work efficiency, safeguard work is stable and reduce the objects such as cost of production.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model medium power switching mechanism.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the utility model describes a kind of powershift mechanism for electric actuator, comprises handwheel 1, manual shaft 2 and body 11; Be provided with limit switch 7, substrate 10 and motor 12 at the top of body 11, and motor 12 is positioned on substrate 10;
Meanwhile, Compress Spring 3, guide rod 4, cylindrical compression spring 5, positioning bead 6, bevel gear 8 and output screw mandrel 9 is disposed with in the inside of body 11 to the one end away from handwheel 1 near one end of handwheel 1; And output screw mandrel 9 is fixed on body 11, substrate 10 is then fixed on the upper surface of body 11 by bolt (not marking in the drawings), and motor 12 is connected with output screw mandrel 9 by gear simultaneously, and in addition, handwheel 1 manually axle 2 is connected with bevel gear 8.
Preferably, conveniently manually-operable, so handwheel 1 is provided with handle 11, is arranged on body 11 top by limit switch 7 and near one end of handwheel 1 simultaneously, and motor 12 is then arranged on body 11 top and away from one end of handwheel 1.
Further, by being fixed on body 11 by output leading screw 9, and substrate 10 is bolted on body 11, so just forms the body shell parts of execution device.And fixed electrical machinery 12 on the substrate 10, motor 12 is driven by gear transmission and exports screw mandrel 9 and rotate, open or close valve with this; Simultaneously, limit switch 7 be drive guide rod 4 and manual shaft 2 by cylindrical compression spring 5 coordinate the disconnection reaching limit switch 7 with closed, under the control of automation, make motor 12 normal with quit work, thus reach electric actuator manual and electronic between the effect that switches.
The working principle of the utility model medium power switching mechanism is:
When final controlling element is electronic, namely motor 12 works to drive and exports screw mandrel 9 switch valve; Now, handwheel 1 does not stress, and Compress Spring 3 plays the effect of axial restraint, handwheel 1 can not be moved forward and engage with bevel gear 8, and cause handwheel 1 to rotate, and causes final controlling element to stop or personal injury;
When final controlling element needs manual under motoring condition, only need in handwheel 1 axial direction applying thrust forward, handwheel 1 is advanced about 5mm on home position, and hear the sound of " click ", now precalculated position shifted onto by handwheel 1, guide rod 4 arrives in the groove of manual shaft 2 under the effect of cylindrical compression spring 5, limit switch 7 is made to transfer off state to by original closed state, pass through Automated condtrol, motor 12 quits work, again handwheel 1 is pushed away 5mm forward, gear now in manual shaft 2 and bevel gear 8 engage each other, positioning bead 6 sticks into draw-in groove simultaneously, manual shaft 2 axial position is fixed, driven by rotation handwheel 1 again and export screw mandrel 9 switch valve.
When final controlling element is under manual mode and when needing to recover electronic: only need apply pulling force backward on handwheel 1 axial direction, handwheel 1 is made to retreat 5mm in manual position, and hear the sound of " click ", positioning bead 6 leaves the draw-in groove of manual shaft 2, now handwheel 1 falls back on precalculated position, and gear in manual shaft 2 and bevel gear 8 disconnect; Then handwheel 1 is pulled back 5mm again, guide rod 4 leaves the groove of manual shaft 2, limit switch 7 is made to transfer closed state to by original off state, pass through Automated condtrol, motor 12 is resumed work, driven by motor 12 and export screw mandrel 9 switch valve, this mechanism prevents people when hot-line work, occurs the personal injury caused because of misoperation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
