It is electrically connected with the contactor of lifter motor electric power loop；When opening protective door 2-1, the first keeper 2-1-1 and travel switch
22 phase separations, at this time, travel switch 22 is in off-state, so that lifter motor electric power loop is disconnected, in this way, even if having behaviour
Make personnel's manipulation elevator by mistake, can not cause elevator normal operation；Conversely, when closing protective door 2-1, the first keeper 2-
The direct acting piston 3-3-1 of 1-1 and travel switch 22 offset, and at this time, travel switch 22 is in conducting state, so that lifting is electromechanical
Electromechanical resource loop is also in conducting state, so, it is allowed to which operating personnel's normal operating is run, and is realized and is only closed in protective door 2-1
It just can turn on lifter motor electric power loop when closing, open protective door 2-1 and be just disconnected lifter motor electric power loop, in this way,
Not only effectively prevent maloperation, but also improve the safe to use of elevator, be not susceptible to personnel casualty accidents.It is if certainly anti-
Protect the door that door 2-1 is single open-type to design, the first keeper 2-1-1 is on protective door 2-1, and the first keeper set 2-1-2 and stroke
Switch 22 is installed on the doorframe or fixed wall of protective door 2-1.
It is shown in Figure 9, in order to which more firmly, the top of the protective door 2-1 is equipped with second after closing protective door 2-1
Keeper 2-1-3, the position corresponding with the second keeper 2-1-3 on protection well 2 are equipped with the second keeper set 2-1-4.
During present invention installation, protection well 2 is installed in workshop, and protection well 2 is built to highest floor from bottom building, often
The protective door 2-1 of door structure is respectively provided with one layer of protection well 2, and two groups of connection are equipped with the protective door 2-1 per floor
Locking device 3, interlock 3 are respectively provided at the both sides of protection well 2, or other suitable positions, the driving lever 4 of interlock 3
It is hinged with corresponding protective door 2-1, must when the stop layers platform that lifting carrier 1 is risen or fallen to some floor loads and unloads material
The second keeper 2-1-3 must be first opened, the second keeper 2-1-3 and the second keeper is covered 2-1-4 phase separations, then open the first keeper 2-
1-1, makes the first keeper 2-1-1 and the first keeper cover 2-1-2 phase separations, when then opening the protective door 2-1 of door structure, two
A door 21 drives driving lever 4, driving lever 4 to drive oscillating rod 5 to swing successively at the same time, and oscillating rod 5 drives follower lever 6 to move, driven
Bar 6 drives pin 7 to be slided in sliding sleeve 8, and drives in the insertion lifting carrier 1 of pin 7, and lifting carrier 1 is generally frame-type and sets
Meter, if lifting carrier 1 designs for confined space, then needs to be provided with insertion hole, facilitates pin 7 to be inserted into.When protective door 2-1 is closed
When closing, the extraction out of lifting carrier 1 of pin 7, is then shut off the second keeper 2-1-3, the second keeper 2-1-3 is inserted into the second keeper
Cover on 2-1-4, turn off the first keeper 2-1-1, the first keeper 2-1-1 is inserted on the first keeper set 2-1-2, the first keeper 2-
The direct acting piston 3-3-1 of 1-1 and travel switch 22 offset, and at this time, travel switch 22 is in conducting state, so that lifting is electromechanical
Electromechanical resource loop is also in conducting state, so, it is allowed to which operating personnel's normal operating is run, and has reached that " door expense enters, Men Guanxiao
Go out " effect, avoid operating personnel because neglect will lifting carrier 1 do not fix just unload, pin 7 is not extracted out after unloading and is just opened
Adverse consequences caused by dynamic button, ensures personal safety, and avoids that security incident occurs, and improves degree of safety, and structure letter
It is single reliable.
