Description
Technical field
The present invention relates to elevator toe guard technical field, specially a kind of elevator folds toeguard.
Background technique
With the quickening of urbanization process, the demand that elevator is installed in old residential area transformation additional is also more and more, but due to certain
Reason, the pit for installing elevator additional do not reach requirement.In order to cope with such case, come into being for the elevator of shallow pit, still
Common toe guard of elevator car due to length issue, the case where when being unable to satisfy shallow pit, if toeguard is done it is short if meet not
Standard.
Summary of the invention
The purpose of the present invention is to provide a kind of elevators to fold toeguard, foldable in bottom, guarantees to operate normally,
Remaining floor stretching, extension, shields, to solve the problems mentioned in the above background technology in rescue.
To achieve the above object, the invention provides the following technical scheme: a kind of elevator folds toeguard, including toeguard,
The folding and stretching, extension of the toeguard are controlled by hydraulic stem, and the fixing end of hydraulic stem is mounted on ceiling board, and hydraulic stem stretches
End is fixedly connected on toeguard.
Preferably, the toeguard connects lever in extended state, and keeps toeguard in vertical direction by lever
Movement.
Preferably, the lever connects lever mechanism, and lever mechanism connects electromagnetism push rod A, and electromagnetism push rod A is mounted on furred ceiling
On plate, the lever and electromagnetism push rod A are linked by lever mechanism.
Preferably, limited position mechanism is arranged in vertical direction in the upper end of the lever.
Preferably, the toeguard is kept in folded state by the latch hook that is connected, and latch hook connects electromagnetism push rod B,
The flexible of electromagnetism push rod B keeps the latch hook disconnected from each other because of the influence of the toeguard gravity.
Compared with prior art, beneficial effects of the present invention are as follows:
This elevator folds toeguard, and there are two types of states, is divided into folded state and extended state, two states pass through hydraulic stem
It is flexible be changed, lever is only capable of being influenced by position-limit mechanism only in movement in vertical direction, and the operation of vertical direction is driven
In the lever mechanism that electromagnetism push rod A expanding-contracting action drives, latch hook can allow toeguard in the case where hydraulic stem failure, make toeguard
Retracted position is kept, the release movement of latch hook depends on the expanding-contracting action of electromagnetism push rod B, so that realization is foldable in bottom,
Guarantee to operate normally, the stretching, extension of remaining floor, the purpose to shield in rescue.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-7, a kind of elevator folding toeguard, including toeguard 1, folding and the stretching, extension of toeguard 1 is please referred to be controlled by
The fixing end of hydraulic stem 2, hydraulic stem 2 is mounted on ceiling board, and the telescopic end of hydraulic stem 2 is fixedly connected on toeguard 1.
In the above-described embodiments, toeguard 1 connects lever 5 in extended state, and keeps toeguard 1 hanging down by lever 5
Histogram to movement.
In the above-described embodiments, lever 5 connects lever mechanism 4, and lever mechanism 4 connects electromagnetism push rod A3, electromagnetism push rod A3
It is mounted on ceiling board, the lever 5 is linked with electromagnetism push rod A3 by lever mechanism 4.
In the above-described embodiments, limited position mechanism 6 is arranged in vertical direction in the upper end of lever 5, it is ensured that lever 5 is only capable of being limited
The influence of position mechanism 6 is only in movement in vertical direction.
In the above-described embodiments, toeguard 1 is kept in folded state by the latch hook 8 that is connected, and latch hook 8 connects electromagnetism
The flexible of push rod B7, electromagnetism push rod B7 keeps the latch hook 8 disconnected from each other because of the influence of 1 gravity of toeguard.
Working principle: this elevator folds toeguard, and when elevator power failure, hydraulic stem 2 loses retentivity, and toeguard 1 is in weight
Become extended state from folded state under the action of power, at this time one can only movement in vertical direction lever 5 in gravity
Under with toeguard 1 stretch and fall, to bear the active force in the horizontal direction of toeguard 1, play and protect quilt under power-off condition
The effect of oppressive member；
Drive lever mechanism 4 by lever 5 by an electromagnetism push rod A3 (retracting automatically when power loss) after elevator Power resumption
Mention and keeps lifting state；
When elevator, which need to be rescued, puts people position to bottom, toeguard 1 need to be reverted to folded state, personnel enter bottom at this time
Lever 5 is lifted manually behind hole, in place by 1 hand foldable of toeguard, two latch hooks 8 are engaged on toeguard 1, and latch hook 8 is another
One end, because the electromagnetism push rod B7 that power loss retracts automatically is resisted, keeps 1 folded state of toeguard by one；
Electromagnetism push rod B7 movement makes toeguard 1 that can be normally carried out flexible and fold, electromagnetism push rod B7 after elevator Power resumption
It can realize that delay is retracted by increasing the modes such as capacitor with electromagnetism push rod A3, guarantee that toeguard 1 can be due to gravity in power loss
Slow stretching, extension.
In summary: this elevator folds toeguard, and there are two types of states, is divided into folded state and extended state, two states
Flexible by hydraulic stem 2 is changed, and lever 5 is only capable of being influenced by position-limit mechanism 6 only in movement in vertical direction, and Vertical Square
To operation be driven in electromagnetism push rod A3 expanding-contracting action drive lever mechanism 4, latch hook 8 can allow toeguard 1 hydraulic stem 2 fail
In the case where, so that toeguard 1 is kept retracted position, the release movement of latch hook 8 depends on the expanding-contracting action of electromagnetism push rod B7, thus
Realize, guarantee normal operation foldable in bottom, the stretching, extension of remaining floor, the purpose to shield in rescue.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
In any actual relationship or order or sequence.Moreover, the terms "include", "comprise" or its any other variant are intended to
