Optionally, above-mentioned left approach switch and right approach switch are the total closed type electronic proximity switch.
Above-described embodiment of the present utility model has been realized following beneficial effect:
1, change former travel switch into the total closed type electronic proximity switch, approach switch can protection against the tide, anti-vibration, induction action (noncontact), has solved that site environment is moist, the impact of vibration and collision impact;
2, because there is the problem in useful life in approach switch electronics integration member, damaging also likely appears in approach switch, in order to prevent after approach switch from damaging not causing push rod, gearbox, motor to damage, approach switch adopts the normal opened contact formula, when push rod arrives left end, right approach switch action connection point disconnects, and motor stops; When push rod arrives right-hand member, left approach switch action connection point disconnects, and motor stops; When approach switch damages, node remains open state, and motor does not start, and protection push rod, gearbox, motor can not damage by exertin.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is that in correlation technique, controlled plant moves to left end motor automatic stop schematic diagram;
Fig. 2 is that in correlation technique, controlled plant moves to right-hand member motor automatic stop schematic diagram;
The electric pushrod device schematic diagram that electric pushrod and motor damage that prevents that Fig. 3 is an embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not paying under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
