Extract latch, fixed link breaks away from adapter plate under the effect of spring restoring force, and the flange on the fixed link separates with electric switch simultaneously.
The present invention adopts the catch gear form of double insurance: when fixed link be horizontally through anti-fall support and adapter plate and by the latch location after, car can not move up and down, this locks for mechanical type; Simultaneously, the flange on the fixed link contacts with electric switch, allots the electric switch button, cuts off safety return circuit, can't up-and-down movement with the electrical control car, and this locks for electric switch.Double insurance combined action has thus guaranteed that home lift action when running is accurate, guarantees maintenance safety, perfectly safe.
In order to guarantee car locking back stress balance, on the basis of such scheme, described anti-drop device has two, is installed in respectively on two opposed beams and the guide rail, guarantees the steady safety of car mechanical positioning.
On the basis of such scheme, described adapter plate is installed on the guide rail by the guide rail folder that makes things convenient for the position up-down adjustment, and the knock hole on the adapter plate is alignd with through hole on the anti-fall support.
On the basis of such scheme, described fixed link is for supporting the round steel of car weight.
On the basis of such scheme, the bottom of described fixed link is provided with a groove, the inside bottom of described anti-fall rack ventilating hole is provided with the screens point that matches, fixed link is led and prevents that it from rotating, with avoid on the fixed link flange since external force rotate and separate with electric switch.
The installation method of anti-drop device of the present invention is:
Earlier install and fix seat at Li Liangshang, constitute jointly at the leading flank of leading flank and upright beam again and fix anti-fall support on the mounting plane, then, the fixed link that is with spring is from inside to outside inserted two through holes of anti-fall support and the end is stretched out outside the through hole, plug latch in the fixed link end it is not moved;
Electric switch support and electric switch are installed in anti-fall support inboard, at last adapter plate are fixed on the guide rail and wiring, but make car be in normal operating condition, wherein, fixing means as, be fixed on the guide rail adapter plate and wiring with the guide rail folder;
When will be with sedan-chair top during as inspection platform, to the needs position, the upper-lower position of adjustment adapter plate makes the knock hole on the adapter plate align with through hole on the anti-fall support with cage operation; Extract latch, fixed link further is extrapolated in the knock hole that inserts adapter plate, flange on the fixed link contacts with electric switch simultaneously, this moment, the safety return circuit of elevator disconnected, elevator does not respond any signal, fixed link is located with latch in the adapter plate outside again, thus with anti-fall support and adapter plate mechanical caging;
When maintenance finishes need resume work state the time, latch to be extracted, fixed link withdraws from from the knock hole of adapter plate under action of the spring, and flange separates with electric switch simultaneously, and the safety return circuit of elevator recloses.
The invention has the beneficial effects as follows:
1, anti-drop device of the present invention adopts mechanical positioning and electrical control double action, and car can accident not fall when guaranteeing to overhaul, and improves job security, and anti-drop device is located at the position of car near the sedan-chair top, and is easy to install and use;
2, when the adapter plate of anti-drop device adopts guide rail to grip, be convenient to the stand distance of safety of staff, the fixed mode of change traditional design, and be convenient to adjust up and down adapter plate, corresponding with anti-fall support;
3, extract latch after hours at anti-drop device, with the fixed link pushed home, the car state of resuming work changes the collision risk that carelessness may cause that resets of manpower in the past by spring.
