Fig. 2 is the structural representation of the secondary of shearing type lifter of the present utility model near device;
Fig. 3 is the circuit block diagram of the secondary of shearing type lifter of the present utility model near device.
The specific embodiment
As shown in Figures 1 to 3, the secondary of a kind of shearing type lifter of the present utility model is near device, be arranged on the shearing type lifter, this shearing type lifter comprises platform 2, base 1, have the oil cylinder 4 of electromagnetic valve and two groups intersect articulate cut arm 3, cut arm 3 articulated platform 2 and base 1 respectively, comprise: at least one pair of infrared inductor 5, this is above the ground level to infrared inductor 5 and is oppositely arranged on described base 1 both sides, and the infrared ray between two described infrared inductors 5 passes the described descending stroke of cutting arm 3; One receives described infrared inductor 5 signals and controls the control unit of described oil cylinder 4 liftings, connects described infrared inductor 5 and oil cylinder 4 respectively; And the secondary of described oil cylinder 4 liftings of control is near switch.
Described infrared inductor 5 is arranged on the described base of cutting in arm 3 descending strokes 1.
Described infrared inductor 5 is arranged on base 1 top and close described position of cutting the pivoting point of arm 3 and described base 1.
Infrared ray between the described infrared inductor 5 is perpendicular to described plane of cutting arm 3 places.
The terrain clearance of described infrared inductor 5 is 500mm.
Described control unit comprises: one accepts the relay of described infrared inductor 5 signals, connects the electromagnetic valve of described infrared inductor 5 and described oil cylinder 4 respectively;
Described secondary connects the electromagnetic valve of described oil cylinder 4 near switch.
Use of the present utility model is as follows:
Oil cylinder 4 at shearing type lifter shrinks, and cuts that arm 3 constantly descends, and this moment, secondary was in open mode near switch, and relay is in the state with the solenoid valve conduction of oil cylinder 4, the electromagnetic valve of oil cylinder 4 be in electricity condition, oil cylinder 4 continues to shrink.
Drop to liftoff 500mm up to cutting arm 3, at this moment, cut arm 3 and cut off infrared ray between the infrared inductor 5, at this moment, infrared inductor 5 issues a signal to relay, relay gets electric saltus step, disconnect and being connected of the electromagnetic valve of oil cylinder 4, the electromagnetic valve of oil cylinder 4 is in off state, and oil cylinder 4 stops contraction, shearing type lifter keeps this height. and at this moment, the staff around the shearing type lifter has time enough to leave around the shearing type lifter.
After not having the staff around the shearing type lifter, open secondary near switch, the electromagnetic valve of conducting oil cylinder 4 once more, oil cylinder 4 continues to shrink, and cuts arm 3 and continues to descend, up to ground.
If the lifting machine does not drop to the bottom when not adding secondary near switch always, if but added secondary near switch so the lifting machine just be declined by less than the bottom, but drop to certain height just do not descend (generally drop to apart from ground 500mm and stop to descend) this mainly be because secondary is sensed near the inductive head of switch cuts arm and stop decline, at this moment as long as just can drop to the bottom by the switch lifting machine that once descends again, thereby the people around having avoided is not because of noting being pressed onto the pin of oneself.
In summary, the utility model of the present utility model has strengthened safety, avoids the artificial origin and causes safety hazard, has increased the safety of equipment greatly, has reduced the generation of accident.
Above-described embodiment only is used to illustrate technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, can not only limit claim of the present utility model with present embodiment, be all equal variation or modifications of doing according to the spirit that the utility model disclosed, still drop in the claim of the present utility model.
