Abstract
The present invention relates to an elevator hoistway door structure which prevents separation of a hoistway door, wherein shoes are respectively installed in right and left doors, and a sill with a groove guiding the shoe is prepared. The bottom of the shoe is bent and slightly protrudes. Inside the groove on the sill, a slit corresponding to the protrusion is formed. According to the present invention, the structures of the shoe and sill prevent separation of the door, and reinforces the entire strength of the door, reducing unnecessary expenses for preventing separation of the door. Furthermore, when abnormal impact or power is applied to the hoistway door and the hoistway door is accidentally opened, this invention prevents a user from falling into the shaft.
Description
Technical field
The present invention relates to the Anti-isenagage structure of elevator shaft door, more specifically, relate to the Anti-isenagage structure of such elevator shaft door, this structure, by strengthening the binding force of hoistway door of closed condition, to prevent the accident because external force is opened and causes thus.
Background technology
Usually, hoistway door is arranged on the place that passenger can directly touch compared with any part of elevator, easily causes mischief and the abnormal accident of passenger.
As shown in Figure 1, be provided with offside door LD and offside door RD in the hoistway of elevator, offside door LD is connected with the respective connecting panel 400 of hoistway door device respectively with the top of offside door RD.
In addition, formed in the bottom of offside door LD and offside door RD and lead boots (shoe) 100, and form sill 200 in hoistway bottom, embed wherein to make above-mentioned boots 100 of leading and guide.
Therefore, during opening and closing offside door LD and offside door RD, by the driving of connecting panel 400 with lead boots 100 and drive with the guiding of sill 200 on-off action having carried out door.
Be following structure: connecting panel 400 is mutually connected by lead-in wire 300 in hoistway door device, as a mobile side door LD, receive power by the lead-in wire 300 connecting another side door RD and open or close, or each connecting panel is carried out action by driving respectively, and top is fixed by door connecting panel 400 when closing, although this connecting panel 400 is connected with lead-in wire 300, but it is only interconnected dynamic in sway phase, when applying to impact before a side door LD lower end, another side door RD resists the intensity of thrust and the hoisting force caused by such impact for support door or quality can not bring any impact.
Therefore, as shown in Figure 2, there are the following problems: due to unavoidable accident, when door LD or RD occurs extremely to impact (being represented by arrow), when the door impacted does not have enough intensity, larger distortion can occur, and the boots 100 of leading playing guiding function in bottom can disengaging from the groove 210 of sill 200.
Summary of the invention
The present invention researches and develops to solve the aforementioned problems in the prior, the object of the invention is to, a kind of Anti-isenagage structure of elevator shaft door is provided, it is not when needing the intensity greatly improving hoistway door, add the function avoided as the sill of basic reason and the disengaging of hoistway door, thus not only fundamentally prevent from departing from and guarantee the safety of user, also developed structure with low cost, help to manufacturer's band.
In order to achieve the above object, the Anti-isenagage structure of elevator shaft door of the present invention is included in bottom and is respectively equipped with the offside door and offside door of leading boots and has for guiding above-mentioned sill of leading the groove of boots, and lead the lower ends bent of boots by above-mentioned and form short projection, form the otch corresponding with above-mentioned short projection at the medial surface of the groove of above-mentioned sill.
According to the present invention, such effect can be obtained: even if abnormal impact or power are applied in hoistway door, because application stops the structure leading boots and sill departing from or fundamentally suppress the door departed from, therefore reinforced door entirety intensity and make it not depart from, reducing unnecessary expense simultaneously, preventing from impacting and recurrent, door to be made by departing from user or resident crash into accident in hoistway due to such exception.
