Lower end jacks up annulus, with the relative movement of bolt and ring set, is fallen behind the inside that annulus enters ring set by Safety detent catch for door
Firmly;When opening safety door, ring set is inwardly pulled, bolt is removed from ring set, and the lower end of ring set jacks up annulus, with ring set
Mobile, annulus is removed from the inside of ring set and is fallen, and safety door is opened.
Scheme is further: the loop chain is three, and three loop chain upper, middle and lower layouts link together fence post, grid
The interval of column column is 100mm to 120mm, and folding net metal net is equipped in the fence post of the safety door.
Scheme is further: the ring set is to stand after being bent by the round steel that diameter is 6mm to 8mm with safe doorjamb fence
Column welds to be formed, and the diameter of the annulus is not less than 50mm.
Scheme is further: the sliding self-locking device is safety door for cage second safety lock, and the safety door for cage is also
It is provided with the first safety lock, the first safety lock includes tapered end and latch post with lockhole, and tapered end is arranged in cage doorway frame
On, latch post be arranged in safe doorjamb fence post, when closed safe behind the door, latch post be inserted into tapered end lockhole will be safe
Door lock is lived, and when needing to open safety door, the lockhole post-tensioning moving ring sleeve for pulling latch post that latch post is made to be detached from tapered end beats safety door
It opens.
The beneficial effect of the utility model compared with prior art is: improving the peace of coal mine shaft lining elevator personnel transport
The labor intensity of worker is effectively reduced in Quan Xing, easy to operate;It effectively prevent catching on safety door for cage because of external force, safety door is lifted
It rises;Unreliable because vibrating, sliding the safe door latch apparatus of reason when safety door is closed, personnel caused by safety door is opened fall well
Casualty accident is avoided due to accident generation and bring life and property loss.
The utility model is described in detail with reference to the accompanying drawings and examples.
