Abstract
The invention relates to a safe electromagnet device for lifting of an elevator car. The safe electromagnet device for lifting of the elevator car, provided by the invention, comprises an elevator car body 1, an electromagnet 2 and iron posts 3, and is characterized in that the electromagnet 2 is arranged on the side of a door of the elevator car body 1; one iron post 3 is arranged on a doorframe at the entrance/exit of an elevator at each floor; the height from the electromagnet 2 to the ground of the elevator car body 1 is equal to the height from each iron post 3 to the ground of the corresponding floor; the electromagnet 2 is connected with a power supply and an elevator control system. The safe electromagnet device is simple in structure and relatively low in production cost and has the function of guaranteeing the safety of passengers, and personal casualty caused when the elevator car is accidentally out of control in lifting is prevented.
Description
Technical field
The present invention relates to a kind of lift car elevating safety electromagnet apparatus, especially a kind of electromagnet apparatus with protection lift car passenger security function.
Background technology
Existing lift car does not arrange the elevating safety electromagnet apparatus of protection passenger security function, causes injures and deaths as car is surprisingly elevated not stop passenger to be blocked.Restaurant, shaba District one, 02 month Chongqing on the 08th in 2009 baggage elevator has an accident suddenly, and car lands vertically to negative second floor from flat street floor, so that restaurant one room attendant unfortunately falls dead, and accident causation is caused by baggage elevator lifting cable breaks.In morning on October 7th, 2012, the elevator burst on building ground, agglomerate town one, Pudong New District is unexpected, and the Anhui nationality woman of 48 years old is stuck in 6 upstairs, causes that it is dead then and there.On September 14th, 2014, at dusk, in an elevator of school district, Huaqiao University Xiamen Main Teaching Building C4, boy student did not surprisingly stop to be died in car by mounting board due to car.
The utility model being 02816712.0 as number of patent application relates to a kind of safety guard from car top maintenance of elevator systems, this patent is on car top region, be fixed with a vertical column: in one embodiment, and the clamp load that cylinder can bear is greater than the disengaging load of car drive mechanism; In another embodiment, a safety is girdled the waist and is connected to the near top of cylinder by a hawser; The vertical column of this application is arranged on car top region, and object protects the staff stood on traction drive elevators top, instead of protect the safety of passenger in lift car; And this application does not solve the problem that the unexpected lifting out of control of lift car can cause casualties.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of lift car elevating safety electromagnet apparatus, can prevent the unexpected lifting out of control of lift car from can cause casualties, there is protection passenger security function.
Its technical scheme is: a kind of lift car elevating safety electromagnet apparatus, comprise car 1, electromagnet 2, iron prop 3, it is characterized in that: described electromagnet 2 is arranged on car 1 limit, described iron prop 3 is arranged on the doorframe of each floor elevator gangway, described electromagnet 2 is identical apart from the floor level of each floor with iron prop 3 apart from the height on car 1 ground, and electromagnet 2 connects power supply and apparatus for controlling elevator.
As optimization, a kind of lift car elevating safety of the present invention electromagnet apparatus, is characterized in that: when elevator lifting is to each floor, and the described electromagnet 2 generation magnetic field that switches on power contacts with the iron prop 3 of each floor elevator gangway.
As optimization, a kind of lift car elevating safety of the present invention electromagnet apparatus, is characterized in that: described iron prop 3 makes the doorframe of floor elevator gangway.
As optimization, a kind of lift car elevating safety of the present invention electromagnet apparatus, is characterized in that: doorframe and the floor building of described floor elevator gangway link together; Electromagnet 2 switches on power and produces magnetic field when contacting with the iron prop 3 of each floor elevator gangway, and the doorframe of floor elevator gangway can bear elevator and surprisingly be elevated produced load.
Principle of work of the present invention: when lift car be elevated to each floor open elevator door time, electromagnet 2 switches on power and produces magnetic field and contact with the iron prop 3 of each floor elevator gangway and inhale surely, can prevent the unexpected lifting out of control of lift car, such people just can pass in and out safely elevator (car); Solve the problem that the unexpected lifting out of control of existing lift car can cause casualties.
Advantage of the present invention: 1, have protection passenger security function, can solve the problem that the unexpected lifting out of control of lift car can cause casualties.2, simple structure, productive costs is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: car 1, electromagnet 2, iron prop 3.
Detailed description of the invention
Below embodiments of the invention are described in detail by reference to the accompanying drawings.
Embodiment 1: as shown in Figure 1, a kind of lift car elevating safety electromagnet apparatus, comprise car 1, electromagnet 2, iron prop 3, it is characterized in that: described electromagnet 2 is arranged on car 1 limit, described iron prop 3 is arranged on the doorframe of each floor elevator gangway, described electromagnet 2 is identical apart from the floor level of each floor with iron prop 3 apart from the height on car 1 ground, and electromagnet 2 connects power supply and apparatus for controlling elevator.
