As shown in fig. 3, the direct-acting type travel switch 32 includes a protruding pin 32a contacting the pressing portion 31, a return spring 32b pushing the protruding pin 32a to move toward the pressing portion 31, and a switch housing 32c accommodating the protruding pin 32a and the return spring 32b, one end of the protruding pin 32a located in the switch housing 32c is connected to a double-headed switch, the double-headed switch includes a closing switch 32a1 enabling the locking assembly to lock the openable and closable door body 2 and an opening switch 32a2 enabling the locking assembly to unlock the openable and closable door body 2, and the switch housing 32c is provided with a first circuit terminal 32c2 for engaging with the opening switch 32a2 and a second circuit terminal 32c1 for engaging with the closing switch 32a 1. When the convex pin 32a is abutted against the pressing part, the opening switch 32a2 of the double-head switch is communicated to the first circuit end 32c2 matched with the opening switch 32a2, so that the driving piece of the locking assembly drives the pin shaft to be drawn out of the door body shaft sleeve and leave the door body shaft sleeve, and the openable door body can be opened in a closed state, so that the elevator door can be opened only when the position of the elevator car reaches the floor and is stable, and personnel or materials can enter the elevator to be conveyed.
When the lift car 5 of the lift elevator ascends or descends to enable the pressing part arranged on the lift car to be far away from the convex pin, the convex pin is ejected out by the reset spring 32b, the closing switch 32a1 of the double-end switch is communicated to the second circuit terminal 32c1 matched with the closing switch 32a1, so that the driving piece driving pin shaft of the locking assembly extends into the door body shaft sleeve to play a role in locking the openable and closable door body in a closed state, the openable and closable door body cannot be opened in the process of ascending or descending of the lift elevator, the safety accident caused by the fact that people or materials enter the lift when the lift car of the lift elevator does not reach the floor and is stable when the lift car of the lift elevator does not reach the floor is avoided, and the problem that the potential safety hazard is caused by the fact that the lift car of the lift elevator is opened.
As shown in fig. 3, two ends of the pressing portion 31 are provided with pushing inclined surfaces 31a for pushing the protruding pins 32a to make the protruding pins 32a slide on the pressing surface, so that the protruding pins 32a can be better connected with the pressing portion.
As shown in fig. 1, the locking assembly 4 includes a frame shaft sleeve 41 disposed on the door frame 1, a door shaft sleeve 42 disposed on the openable door 2, a pin 43 inserted into the frame shaft sleeve 11 and the door shaft sleeve 21 for locking the openable door 2 in a closed state, and a driving member 44 for driving the pin 43 to enter or leave the door shaft sleeve 21, where the driving member 44 is electrically connected to the position measuring mechanism 3.
The driving member 44 is an electromagnet disposed on the door frame 1, in this embodiment, the pin is made of metal such as iron, stainless steel, and the like, which has magnetic material, and the travel switch 32 of the position measuring mechanism 3 is communicated to the electromagnet through a connecting wire 6. The signal of the state of the openable door body in the closed state is locked by being electrically connected with the direct-acting travel switch, the electric signal is converted into a signal of the driving piece of the locking assembly for driving the pin shaft to stretch into or leave the door body shaft sleeve, and the driving pin shaft is driven to stretch into or leave the door body shaft sleeve by the on-off state of the electromagnet. When the electromagnet is electrified, the pin shaft is pulled out from the door body shaft sleeve under the action of the attraction force of the electromagnet, and the openable door body can be unlocked and opened. When the electromagnet is powered off, the pin shaft falls down from the unattractive electromagnet and extends into the door body shaft sleeve to prevent the openable door body from being opened, so that the openable door body in a closed state is locked.
Certainly, as an alternative technical scheme of driving piece, driving piece 44 is for locating drive actuating cylinder on the door body frame 1, drive the inflexible end of actuating cylinder and fix on the door body frame, and scalable end and round pin hub connection leave or stretch into in the door body axle sleeve from a body axle sleeve through cylinder drive round pin axle to realize the effect of the locking openable and closable door body. Specifically, when the telescopic end extends out, the pin shaft extends into the door body shaft sleeve to play a role in preventing the openable door body from being opened. When the telescopic end is contracted, the pin shaft is drawn out from the door body shaft sleeve to play a role in preventing the openable door body from being opened. The solution for driving the cylinders is not shown in the drawings.
In the elevator of the embodiment, the direct-acting travel switch of the position measuring mechanism of the security detection device of the elevator door corresponds to the touch part of the elevator car so as to detect whether the position of the elevator car reaches the floor and is stable, after the convex pin of the direct-acting travel switch is pushed back into the switch shell by the touch part, the direct-acting travel switch converts the position information of the elevator car into an electric signal which can be opened by the openable door body, the driving piece electrically connected with the direct-acting travel switch drives the pin shaft to be drawn out of the shaft sleeve of the door body so as to enable the openable door body to be in an openable state, and after the openable door body is manually opened by a worker or a production worker, the worker or materials can safely enter the elevator; when the elevator door is closed manually and the elevator is in the ascending or descending process, the contact part outside the elevator car leaves the direct-acting travel switch, the convex pin of the direct-acting travel switch is ejected outwards under the action of the reset spring to be in jacking connection with the contact part again, at the moment, the position information of the elevator car is converted into an electric signal for closing the openable door body, a driving piece electrically connected with the direct-acting travel switch drives the pin shaft to enter the door body sleeve to lock the openable and closable door body in a closed state, the elevator door can not be opened in the ascending or descending process of the elevator, so that the safety accidents possibly caused by the fact that the elevator door is opened when the elevator car does not reach the floor and is stopped stably and people or materials enter the elevator are avoided, and the problem that the potential safety hazard possibly caused by the fact that the elevator door of the existing elevator is opened when the elevator car does not reach the floor and is stopped stably is solved.
