Example 1
The embodiment provides a door lock device for an elevator landing door, wherein the elevator landing door comprises a door head plate and a track transversely and horizontally arranged on the door head plate, and a left hanging plate and a right hanging plate which can be oppositely opened and closed between an opening station and a closing station are hung on the track; the door lock device comprises a fixed lock hook 1, a movable lock hook 2, a connection and disconnection switch 3 for transmitting on-off signals and a cleaning mechanism 4 for cleaning the connection and disconnection switch 3; the fixed latch hook 1 is arranged on the door head plate; the movable lock hook 2 can be arranged on the right hanging plate in a swinging and switching mode between an unlocking station and a locking station, and when the right hanging plate is positioned at a closing station, the movable lock hook 2 is swung to the locking station to be matched with the fixed lock hook 1 to realize transverse limiting buckling; the on-off switch 3 comprises a first contact block 31 linked with the movable locking hook 2 and a second contact block 32 arranged on a door head plate, and when the movable locking hook 2 is in limit buckling with the fixed locking hook 1, the first contact block 31 is in contact with the second contact block 32 to trigger the on-off switch 3 to be switched from an off state to an on state; the cleaning mechanism 4 comprises a fan 41 and a guide pipe 42, the fan 41 is mounted on the right hanging plate, one end of the guide pipe 42 is communicated with the fan 41, and the other end of the guide pipe 42 extends to the on-off switch 3 to clean the on-off switch 3.
In this embodiment, the flow guide tube 42 is connected to the movable hook to enable the flow guide tube 42 to be always opposite to the first contact block 31, the fan 41 is started when the movable hook 2 swings and switches between the unlocking station and the locking station, when the movable hook 2 switches from the locking station to the unlocking station, the flow guide tube 42 only cleans the first contact block 31, and when the movable hook 2 switches from the unlocking station to the locking station, the flow guide tube 42 simultaneously cleans the first contact block 21 and the second contact block 32, because the first contact block 31 is movable, and the second contact block 32 is always located in the dust cover, the probability that the first contact block 31 contacts dust is high, and by adopting the above design, the first contact block 31 is mainly cleaned, and the maintenance time can be more effectively prolonged.
Specifically, the right side of the movable locking hook 2 is rotatably connected to the right hanging plate through a fixed shaft 21, and one end of the movable locking hook 2, which is close to the fixed locking hook 1, is bent downwards to form a hook body 22 which can swing from top to bottom and is matched and buckled with the fixed locking hook 1.
The applicant finds that the existing door lock device uses a metal sheet as a contact point, and the elasticity of the metal sheet is used for ensuring the contact and then the connection is achieved, so that the contact life is not long, and in order to keep the first contact block 31 and the second contact block 32 to have good contact on the premise of prolonging the service life, in the embodiment, the second contact block 32 is installed on the door head plate through the spring frame 321, and when the first contact block 31 and the second contact block 32 are in contact, the spring frame 321 is compressed, so that the second contact block 32 is pressed upwards to keep good contact with the first contact block 31.
Meanwhile, by adopting the existing design, the arc phenomenon is also easily caused, and in order to avoid the arc phenomenon, in this embodiment, the door head plate is provided with the anti-interference arc extinguisher 6 for preventing the arc from occurring when the first contact block 31 and the second contact block 32 are connected, specifically, the anti-interference arc extinguisher is an MCR-P anti-interference arc extinguisher 0.1UF +120R/275v.
In order to reduce the dust source, in this embodiment, the first contact block 31 and the second contact block 32 are covered with a dust cover 5, and in order to facilitate the maintenance personnel to observe the dust deposition of the first contact block 31 and the second contact block 32, the dust cover 5 is preferably a transparent cover.
The principle that this device realized does: fix fixed latch hook 1 on the door head board, fix activity latch hook 2 on the board of right hanging (require the installation to guarantee its position degree simultaneously activity latch hook 2 can lift in a flexible way, receive the spacing of layer door link board downwards and can not the lower hem), when the layer door was closed, in the latch hook of fixed latch hook 1 was blocked to activity latch hook 2 front end, first touch multitouch 31 and second touch multitouch 32 switch-on, spring bracket 321 guarantees first touch multitouch 31 and second touch multitouch 32 in close contact with, switch-on anti-interference arc extinguisher 6 in contact process is in order to prevent that the electric arc from producing. When the layer door opens the door, at first will go up gyro wheel 7 and up push down under sedan-chair door sword effect, use the contact point disconnection, the fixed axle 21 that the fixed latch hook 2 of fixed latch hook 1 and movable latch hook 2 front end throw off in through gyro wheel 8 is fixed on right link plate (because of there is the spacing nail on layer door link plate, it can not the downswing, nevertheless guarantee that it can go up the activity earlier), switch on fan 41 simultaneously, the fan rotates, blow wind to the contact point department (open and close all switch on and blow under honeycomb duct 42's effect, make the contact clean.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
