The first locking bar is close to the first electromagnet after electricity.
Compared with the prior art, the utility model has the following beneficial effects:
When realizing rescue, carriage is locked in the position being aligned with a certain leveling, carriage is avoided to lead because of weight change
Carriage automatic lifting is caused, safety when personnel's discrepancy carriage in rescue operations is ensure that, improves reliability, while avoiding
The movement of the first locking bar is driven when carriage is aligned with leveling again and carriage itself shake and the first locking bar is caused to be difficult to lockhole on jam plate
The problem of alignment, improves the probability that the first locking bar is inserted into lockhole.
The further advantage, target and feature of the utility model will be partially reflected by the following instructions, and part will also pass through
Research and practice to the utility model and be understood by the person skilled in the art.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the locking device for elevator safety rescue system.
Appended drawing reference: jam plate 1, the first locking bar 2, mounting plate 3, the first spring 4, the first electromagnet 5, carriage 6, guide rail 7, limit
Position mechanism 8, guide plate 9.
Specific embodiment
In order to make technological means of the utility model, creation characteristic, reach purpose and effect is more clear and is easy to
Understand, the utility model be further elaborated with reference to the accompanying drawings and detailed description:
As shown in Figure 1, the present embodiment proposes a kind of locking device for elevator safety rescue system, comprising: jam plate
1, the first locking bar 2, mounting plate 3, the first spring 4 and the first electromagnet 5, offer installation cavity at the top of the carriage 6 of elevator,
First electromagnet 5 is installed, the first electromagnet 5 is connected to power supply unit, is provided with by the first electromagnet 5 and is located at installation in installation
Intracavitary mounting plate 3, the first locking bar 2 are made of iron material, and mounting plate 3 is fixed to 2 one end of the first locking bar, and the first locking bar 2 is another
For being inserted into jam plate 1 after being pierced by installation cavity, jam plate 1 is mounted between two sliding rails of elevator for one end, the first electromagnet 5 and lock
Determine device driving module to be connected；
The upper end of jam plate 1 and the lower end of jam plate 1 are separately installed with two guide plates 9, and guide plate 9 is connect backward with jam plate 1
Extend away from 5 direction of the first electromagnet, the first locking bar 2 is able to maintain under 4 elastic force of the first spring and is inserted into jam plate 1, guide plate 9
For the first locking bar 2 to be directed to jam plate 1, the first locking bar 2 is close to the first electromagnet 5 after the first electromagnet 5 is powered.Jam plate
1 and guide plate 9 can be an integral structure, or split type structure, as long as merging as the shape of such as figure.
The first electromagnet 5 is constantly in energized state and leads to waste of energy when working normally in order to avoid elevator, locks
Device further include: position-limit mechanism 8, the telescopic direction of 8 output section of position-limit mechanism is vertical with the telescopic direction of the first locking bar 2, limit
The output section of mechanism 8 is for keeping the first locking bar 2 close to the state of the first electromagnet 5.
Locking device control module includes first switch triode, and the first electromagnet 5 is connected by first switch triode
To the specific store power module of power supply unit, the base stage of first switch triode is the control terminal of locking device control module,
The control terminal of locking device control module is for being connected to safe rescue master control borad (being equivalent to a controller).
Position-limit mechanism 8 includes: the second electromagnet, the first locking bar 2 and second spring, is equipped with by the first electromagnet 5
Second electromagnet, be equipped with by the second electromagnet carriage 6 to lock with the second of 2 movement in vertical direction of the first locking bar relatively
Bar, the second locking bar are connected to second spring one end, the carriage 6 of second spring other end connection, and the second electromagnet is opened by second
It closes triode and is connected to specific store power module, the base stage of second switch triode is connected to safe rescue master control borad.
In rescue operations, before carriage 6 does not reach level position, it is disconnected that safe rescue master control borad just controls the first electromagnet 5
Electricity, the second electromagnet are powered, and the second locking bar does not stop mounting plate 3 to the position far from the first electromagnet 5 after the second electromagnet is powered
Movement is set, locking bar stretches out carriage 6 under 4 elastic force of the first spring, (the corresponding installation of every floor when the first locking bar 2 is close to jam plate 1
Have a jam plate 1), the beginning of the first locking bar 2 is contacted with guide plate 9, and the first locking bar 2 is slowly squeezed into sedan-chair under the guiding of guide plate 9
In compartment 6, lockhole is offered on jam plate 1, slowly the first locking bar 2 slides at jam plate 1, since the effect of guide plate 9 enables to
First locking bar 2 does not hinder the lifting of carriage 6, realizes and the first locking bar 2 is expressed in carriage 6, when the first locking bar 2 and lockhole pair
The first locking bar 2 is inserted into lockhole under 4 elastic force of the first spring on time, even if carriage 6 has the power of lifting also insufficient at this time
So that the first locking bar 2 is detached from lockhole, it ensure that carriage 6 is constantly in level position, after will not answering 6 Gravity changer of carriage,
Lead to 6 automatic lifting of carriage after operating condition variation and safety accident occurs.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
