Abstract
The utility model discloses an elevator door safety device. The device is characterized by comprising an inverted Y-shaped nylon transmission belt installed on a door machine driving wheel and a door lock mechanism installed on a door. The device prevents the elevator door from automatically opening by installing the door lock mechanism on the elevator door, and achieves the purpose of preventing the transmission belt from slipping by using the inverted Y-shaped nylon transmission belt to replace a normal transmission belt, thereby effectively improving safety performance of an elevator.
Description
Technical field
The utility model relates to the gate safety device of a kind of safety device, particularly a kind of elevator.
Background technology
At present, in elevator, the problem that elevator cage door is opened automatically is the important safety hidden danger of elevator always, threatens passenger's life security to a certain extent.And elevator cage door door machine drives used driving band and is easy to skid, and has influence on the normal switch of gate.So the safety performance of elevator can not satisfy user's demand.
The utility model content
The purpose of this utility model is, a kind of elevator cage door safety device is provided.It can prevent drive belt slip, prevents that elevator cage door from opening automatically, therefore effectively raises the safety performance of elevator.
The technical solution of the utility model: a kind of elevator cage door safety device is characterized in that: comprise chevron pointing nylon driving band that is installed on the machine drive wheel and the door lock mechanism that is installed on the elevator cage door.
In the above-mentioned elevator cage door safety device, described door lock mechanism comprises quiet latch hook and the moveable lock hook on the two fan translation door that are installed in elevator cage door respectively, moveable lock hook and hook arm are connected as a single entity, the hook arm is connected on the translation door by axle, nearly moveable lock hook one side of hook arm rest is connected with spring, the spring other end is fixed on the translation door, and hook arm end is equipped with unlocking apparatus.
In the aforesaid elevator cage door safety device, described chevron pointing nylon driving band comprises the herringbone grooves on nylon belt body and the nylon belt body.
In the aforesaid elevator cage door safety device, the unlocking apparatus of described door lock mechanism is connected with apparatus for controlling elevator.
Compared with prior art, the utility model prevents that by door lock mechanism has been installed elevator cage door from opening automatically on elevator cage door, and used the transmission of chevron pointing nylon to bring the common driving band of replacement to have reached the purpose that prevents drive belt slip, effectively raise the safety performance of elevator.
Description of drawings
Fig. 1 is the structural representation of the utility model door lock mechanism;
Fig. 2 is the utility model chevron pointing nylon driving band structural representation.
The quiet latch hook of being labeled as in the accompanying drawing: 1-, 2-moveable lock hook, 3-spring, 4-axle, 5-unlocking apparatus, 6-hook arm, 7-nylon belt body, 8-herringbone grooves.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of elevator cage door with safety device, comprise the driving band of installing on a machine, sedan-chair wall, gate, door machine drive wheel and the door machine drive wheel, it is characterized in that: also comprise the door lock mechanism that is installed on the elevator cage door, the driving band that is installed on the machine drive wheel is a chevron pointing nylon driving band.As shown in Figure 1, door lock mechanism comprises quiet latch hook 1 and the moveable lock hook 2 on the two fan translation door that are installed in gate respectively, moveable lock hook 2 is connected as a single entity with hook arm 6, hook arm 6 is connected on the translation door by axle 4, hook arm 6 is connected with spring 3 near moveable lock hook 2 one sides, the spring other end is fixed on the translation door, and hook arm 6 ends are equipped with unlocking apparatus 5.As shown in Figure 2, chevron pointing nylon driving band comprises the herringbone grooves 8 on nylon belt body 7 and the nylon belt body 7.The unlocking apparatus 5 of door lock mechanism is connected with apparatus for controlling elevator.
When elevator door is shut, the squeese pressure that is subjected to lifting behind the quiet latch hook 1 of moveable lock hook 2 contact of door lock mechanism, the pressure that this makes every effort to overcome clothes spring 3, make moveable lock hook around axle 4 rotate and on lift and quiet latch hook 1 interlock, this moment, two fan translation door of elevator were pinned mutually, can not open the door automatically.When elevator need open the door, the control system of elevator can be controlled 5 times pressure hook arms 6 of unlocking apparatus with lifting moveable lock hook 2, reaches the effect of unblanking.This unlocking apparatus 5 can be common drive motor.
The utility model prevents that by door lock mechanism has been installed elevator cage door from opening automatically on elevator cage door, and used the transmission of chevron pointing nylon to bring the common driving band of replacement to have reached the purpose that prevents drive belt slip, effectively raise the safety performance of elevator.
