The specific embodiment
In order to describe the technology contents, structural attitude of the utility model protection door for construction elevator in detail, below in conjunction with embodiment and coordinate accompanying drawing to be described further.
As shown in Figure 1, 2, the utility model protection door for construction elevator, comprise several layers of construction elevator protection cervical orifice of uterus, the construction elevator protection cervical orifice of uterus of described every layer is all controlled the opening and closing of cervical orifice of uterus by control circuit, the pass gate signal of the construction elevator protection cervical orifice of uterus of every layer is controlled intermediate relay with construction elevator again after connecting successively and connected (as shown in Figure 6); Thereby in the situation that the protective door that has guaranteed to occur one deck does not shut, construction elevator all can not carry out descending operation, has guaranteed the safe in operation of construction elevator.The construction elevator protection cervical orifice of uterus of described every layer includes doorframe 3, door leaf 4 and door leaf grid 1; Described door leaf 4 is connected with doorframe 3 by auto-closing Positioning hinge 2, and the upper end of doorframe 3 is provided with electromagnetic lock 5 and approach switch 6, and door leaf 4 is provided with door open button switch 7.Described door open button switch 7 is all located at the back side of door leaf 4, and electromagnetic lock 5 and approach switch 6 are all located at the upper end at doorframe 3 back sides.
The electromagnetic lock that is illustrated in figure 3 the utility model protection door for construction elevator is installed section-drawing; In figure, the direction of arrow is the direction of opening the door, and electromagnetic lock 5 is located at the upper end at doorframe 3 back sides by mounting bracket 9, is provided with electromagnetic lock and inhales iron 8 between electromagnetic lock 5 and door leaf 4.When needs open the door while transporting material for a long time, only protective door need to be opened to maximum rating can position, and protective door can stay open state and not affect and transport material.When needs at closing time, with have gentle hands, gently protective door is pushed away to protective door can automatic door-closing lock (inhaling at electromagnetic lock under the effect of iron) toward the direction of closing the door.
The approach switch that is illustrated in figure 4 the utility model protection door for construction elevator is installed section-drawing; In figure, the direction of arrow is the direction of opening the door, and approach switch 6 is located at the upper end at the doorframe back side by mounting bracket 9.
As shown in Figure 5, the control circuit of the construction elevator of described every layer protection cervical orifice of uterus composes in parallel by the first circuit series and the second circuit series; Described the first circuit series is composed in series by approach switch and relay; The second circuit series is composed in series successively by relay contact, electromagnetic lock and door open button switch.In figure, A is the control circuit principle assumption diagram of ground floor protective door; B is the control circuit principle assumption diagram of the monolateral door of ground floor protective door; The monolateral door of ground floor protective door is composed in parallel by the first circuit series and the second circuit series; Described the first circuit series is composed in series by approach switch SP1 and relay K A1; The second circuit series is composed in series successively by relay contact KA1 ', electromagnetic lock YL1 and door open button switch S B1.
When workmen will enter building from construction elevator bridge case, first open the interior cage door of construction elevator, at this moment protection door for construction elevator electromagnetic lock energising, all protective doors are in the state of locking a door.Press door open button switch, electromagnetic lock power-off, protective door can be opened.If this time, protective door did not open to maximum rating, protective door can be subject to the effect of automatic close door hinge, can automatically close.After protective door is closed completely, approach switch detects pass gate signal, and passes the signal to relay, and relay closes electromagnetic lock obtains electric, and protective door recovers the state of locking a door.
Be below the utility model protection door for construction elevator circuit specific works process:
One, the process of closing the door:
1, after protective door closure, approach switch action, open contact is closed, and approach switch open contact transfers closure to by disconnection.
2, after approach switch open contact closure, relay power is connected, relay energized action, relay normally open contact transfers closure to by disconnection.
3, after relay contact closure, by electromagnetic lock power connection, electromagnetic lock obtains electric, produces superpower magnetic force, in locking state, protective door is pinned, and cannot open.
Two, the process of opening the door:
1, when needs open the door, press door open button switch, door open button switch normally closed contact transfers disconnection to by closure, and electromagnetic lock negative power supply disconnects, electromagnetic lock dead electricity, magnetic force disappears, in unlocking condition.
2, after protective door is opened, approach switch loses pass gate signal, and open contact transfers disconnection to by closure, relay electric-loss.
3, after relay electric-loss, often opening gets an electric shock transfers disconnection to by closure, and electromagnetic lock positive source disconnects, and electromagnetic lock magnetic force disappears, in unlocking condition.
4,, after Dang Men is opened, even if unclamp door open button switch, electromagnetic lock can not switched on (because positive pole has also been disconnected) yet, produces, in unlocking condition without magnetic force.When protective door is finished using, after auto-closing, 1～3 step that repeats the process of closing the door is locked and closed the door.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
