Referring to Fig. 5, voice module 22 is connected with first intermediate relay 13, second intermediate relay 14, the 3rd intermediate relay 15 and contactless switch 16 respectively.When winch in a single day run to the upper end in advance between spacing zone, between the preparatory spacing zone in lower end, between the spacing zone of upper end, between the spacing zone of lower end, when any one of limit position, upper end and limit position, lower end, voice module 22 all can send the prompting of true man's audio alert.For simplifying the warning circuit design; The upper end in advance between spacing zone with the preparatory spacing zone in lower end between the voice suggestion language can be identical; The upper end spacing zone between with the lower end spacing zone between the voice suggestion language can be identical, the voice suggestion language of limit position, upper end and limit position, lower end also can be identical.
Reset switch 24 inserts in the power circuit with contactless switch 16 parallelly connected backs, and pressing reset switch 24 can reset, and connection terminal 23 is used for being connected with each device, and power circuit adopts 380V voltage.Referring to Fig. 7, reel 26 drives through drum shaft 27, and an end of drum shaft 27 is connected with coupler 28, and coupler 28 is connected with the utility model height limitator 29 through input shaft 1, and height limitator 29 is installed on the supporting seat 30.The utility model meets product and carries out Q/WQS009-2010, JB/T4315-97 standard, and meets relevant regulations and the TSG Q7014-2008 regulation of GB6067-85 " safety rules for lifting appliances ".
The principle of work and the process of the utility model are following:
When in the winch upstream or downstream are between the normal area of setting, moving, blue lamp 20 flickers, whether be used for the alert mode of operation normal.
When winch ran between the preparatory spacing zone in upper end, this moment, also between the spacing zone of no show upper end, winch still can normally move this moment.Rote memory cam 6 makes third trip switch 9 be activated; 15 work of the 3rd intermediate relay make its open contact closed, and green light 21 flickers buzzer phone 17 are simultaneously reported to the police; Blue lamp 20 still glimmers; Voice module 22 sends true man's voice suggestion simultaneously, is equivalent to early warning, and the alert winch has run near between the spacing zone of upper end.
When winch ran between the preparatory spacing zone in lower end, this moment, also between the spacing zone of no show lower end, winch still can normally move this moment.Rote memory cam 6 makes fourth line journey switch 10 be activated; 15 work of the 3rd intermediate relay; Green light 21 flickers buzzer phone 17 are simultaneously reported to the police, and blue lamp 20 still glimmers, and voice module 22 sends true man's voice suggestion simultaneously; The same early warning that also is equivalent to, the alert winch has run near between the spacing zone of lower end.
When winch ran between the spacing zone of upper end, under normal circumstances winch can not continue upwards to have moved, but reverse operating still can normally move.Rote memory cam 6 is activated the travel switch 7 of winning, and 13 work of first intermediate relay make de all break off; Blue lamp 20 extinguishes; And connect df, and cutting off the rising control loop shown in Fig. 5 simultaneously, early warning is carried out in amber light 19 flickers; And voice module 22 sends true man's voice suggestion, to reach warning function.
When winch ran between the spacing zone of lower end, under normal circumstances winch can not continue to have moved downwards, but reverse operating still can normally move.Rote memory cam 6 makes second travel switch 8 be activated, and 14 work of second intermediate relay make ac connect; Early warning is carried out in same amber light 19 flickers; Cut off the decline control loop, voice module 22 also sends true man's voice suggestion, to reach warning function.
When winch ran to limit position, upper end, this situation was to run to end position owing to the spacing control fails of fwd or equipment malfunction, and for example in electric control system, the contactless switch iron core is stuck, faults such as contact adhesion.Rote memory cam 6 makes fifth line journey switch 11 be activated at this moment, contactless switch 16 dead electricity, and auxiliary normally closed contact is closed, red light 18 flickers, and the true man's voice suggestion that has voice module 22 to send.
When winch ran to limit position, lower end, this situation also was because foregoing control fails or equipment run to end position owing to fault is malfunctioning.Rote memory cam 6 makes the 6th travel switch 12 be activated at this moment, contactless switch 16 dead electricity, and auxiliary normally closed contact is closed, red light 18 flickers, and the true man's voice suggestion that has voice module 22 to send.Guarantee to cut off automatically the winch main power source simultaneously, realize the spacing requirement of the limit, can prevent that steel rope from oppositely twining, the accident of breaking steel rope takes place.Reliability is high, and safety is good, has realized the acousto-optic warning function of multistage early warning.
