Abstract
The present invention relates to a hoistway door separation preventing device for a lift (elevator). The mounting plate, connector plate or hanger plate of a hoistway door locking device is additionally provided with a separation preventing means in such a way that the separation preventing means can prevent bending of the connector plate and thereby prevent separation of the landing door when the connecting plate might otherwise bend due to an impact to the hoistway door.
Description
Technical field
The present invention relates to a kind of hoistway door separation preventing device for elevator, and relate more specifically to a kind of like this hoistway door separation preventing device for elevator: when hoistway door is during in closed condition, this hoistway door separation preventing device prevents that by the reinforced door power of closing hoistway door is because external force is opened, and prevent because of hoistway door such open the accident causing.
Background technology
Conventionally, elevator shaft door is arranged on such place: passenger can directly contact any other place of door instead of contact elevator, and elevator shaft door is easily subject to passenger's infringement and the impact of accident.
In elevator accident, the percentum that falls into because of user the accident causing in elevator in the time applying intense impact to hoistway door increases greatly.
Although elevator manufacturer take such as the measure such as intensity of strengthening hoistway door, such measure not and cause the burden of manufacturing cost larger.
Fig. 1 is the door that the elevator in correlation technique is shown, Fig. 2 is the enlarged drawing of a part for the structure of cut-away view 1 only.Fig. 3 is the lateral plan that the normal engagement state of elevator door in correlation technique is shown, Fig. 4 is the lateral plan that the engagement state in the time that elevator door in correlation technique separates is shown.
Referring to figs. 1 through 3, elevator generally includes two to four doors, and the top of corresponding door 1a and 1b is connected to connecting panel 2a and 2b.Connecting panel 2a and 2b link together by the wire rod in hoistway door device etc., and if a door moves, another door that receives the power of transmitting by wire rod also moves, and therefore hoistway door 1a and 1b can be opened or closed.And in the time that corresponding connecting panel 2a and 2b are driven, hoistway door 1a and 1b can be opened or closed.In this case, between connecting panel 2a and 2b and track 24, pulley 3a and 3b are set.
As shown in Figure 4, if apply intense impact to hoistway door 1a in this structure, hoistway door may be bending, and the connecting panel 2a that is therefore fixed to the upper end of door may rupture.Thereby the pulley 3a that therefore arrives connecting panel 2a may separate with track 42, therefore the upper end of hoistway door 1a also may separate and cause the generation of falling accident.
Summary of the invention
Therefore, make the present invention to solve the problems referred to above that occur in correlative technology field, keep the advantage that realized by correlative technology field unaffected simultaneously.
The theme that the present invention will realize is to provide a kind of hoistway door separation preventing device for elevator, and this hoistway door separation preventing device that is used for elevator has the anti-separating effect of larger hoistway door, or novelly stops hoistway door to separate with low cost.
In one aspect of the invention, a kind of hoistway door separation preventing device for elevator is provided, this hoistway door separation preventing device that is used for elevator also comprises separation preventing device except adapter plate, connecting panel and boatswain chair, wherein, in the time that described connecting panel impacts bending because applying to described hoistway door, described separation preventing device prevents described connecting panel bending, to prevent that described hoistway door from separating.
According to the present invention, the intensity having reduced for strengthening described hoistway door makes the unnecessary cost of this separation to prevent the abnormal impact because applying to it, and prevents abnormal impact of user or resident's reason and the separation of the hoistway door occurring repeatedly that causes and falling in elevator.
