Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, a folding toe guard for an elevator comprises a toe guard 1, wherein the folding and the extension of the toe guard 1 are controlled by a hydraulic rod 2, the fixed end of the hydraulic rod 2 is installed on a ceiling board, and the telescopic end of the hydraulic rod 2 is fixedly connected to the toe guard 1.

In the above embodiment, the toe guard 1 is connected to the shift lever 5 in the extended state, and the movement of the toe guard 1 in the vertical direction is maintained by the shift lever 5.

In the above embodiment, the lever 5 is connected to the lever mechanism 4, the lever mechanism 4 is connected to the electromagnetic push rod A3, the electromagnetic push rod A3 is mounted on the ceiling plate, and the lever 5 and the electromagnetic push rod A3 are linked by the lever mechanism 4.

In the above embodiment, the upper end of the shift lever 5 is provided with the stopper mechanism 6 in the vertical direction, ensuring that the shift lever 5 can move only in the vertical direction under the influence of the stopper mechanism 6.

In the above embodiment, the toe guard 1 is held by the snap-in connection latch 8 when folded, the latch 8 is connected to the electromagnetic push rod B7, and the extension and contraction of the electromagnetic push rod B7 causes the latch 8 to separate from each other due to the influence of the weight of the toe guard 1.

The working principle is as follows: according to the folding foot protection plate for the elevator, when the elevator is powered off, the hydraulic rod 2 loses the holding force, the foot protection plate 1 is changed into an extension state from a folding state under the action of gravity, and at the moment, a stop rod 5 which can only move in the vertical direction falls along with the extension of the foot protection plate 1 under the action of gravity to bear the action force of the foot protection plate 1 in the horizontal direction, so that the function of protecting trapped people under the condition of power failure is achieved;

after the elevator is electrified, an electromagnetic push rod A3 (automatically retracts when power is off) drives the lever mechanism 4 to lift the stop lever 5 and keep the lifting state;

when the elevator needs to be rescued to the position of people at the bottom layer, the foot protection plate 1 needs to be restored to the folded state, at the moment, people enter a pit and then manually lift the stop rod 5, the foot protection plate 1 is manually folded in place, two locking hooks 8 on the foot protection plate 1 are mutually occluded, the other ends of the locking hooks 8 are propped against by an electromagnetic push rod B7 which automatically retracts due to power failure, and the folded state of the foot protection plate 1 is kept;

after the elevator is electrified again, the electromagnetic push rod B7 acts to enable the foot protection plate 1 to be capable of normally extending and retracting, the electromagnetic push rod B7 and the electromagnetic push rod A3 can achieve delayed retraction through modes of increasing capacitance and the like, and the foot protection plate 1 can be enabled to extend slowly under the action of gravity when power is lost.

In summary, the following steps: this folding toeguard of elevator, there are two kinds of states, divide into fold condition and extension state, two kinds of states change through the flexible of hydraulic stem 2, shelves pole 5 only can receive stop gear 6's influence only at the motion of vertical direction, and the operation of vertical direction is followed from lever mechanism 4 that the flexible action of electromagnetism push rod A3 drove, latch hook 8 can let toeguard 1 under the condition that hydraulic stem 2 became invalid, make toeguard 1 keep flexible state, latch hook 8's release action depends on the flexible action of electromagnetism push rod B7, thereby realize folding when the bottom, guarantee normal operating, all the other floors extend, play the purpose of guard action when the rescue.
