Safe electromagnet device for lifting of elevator car

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 [0001] The invention relates to an elevator car lifting safety electromagnet device, in particular to an electromagnet device with the function of protecting the safety of elevator car occupants. Background technique [0002] The existing elevator car is not equipped with a lifting safety electromagnet device for protecting the safety function of the occupants. If the car is accidentally lifted and lowered, the occupants will be stuck and cause casualties. On February 08, 2009, a freight elevator in a restaurant in Shapingba District, Chongqing suddenly had an accident. Sincerely. On the morning of October 7, 2012, a 48-year-old Anhui woman was stuck on the 6th floor of a construction site in Datuan Town, Pudong New District, and died on the spot. On the evening of September 14, 2014, in an elevator in C4 of the comprehensive teaching building of Huaqiao University Xiamen Campus, a boy died because the car accidentally failed to stop and was trapped in the...

Problems solved by technology

[0003] For example, the utility model with the patent application No. 02816712.0 relates to a safety protection device for maintaining the elevator system from the top of the car. The patent is that a vertical column is fixed on the top area of ​​the car: in one embodiment, the column can withstand The compression load is greater than the disengagement load of the car drive mechanism; in another embodiment, a safety waist is connected by a cable near the top of the column; the vertical column of this application is set on the car top area, The purpose is to protect the staff standing on the top of the traction elevator, not to protect the safety of the occupants in the elevator car; and the application does not solve the problem of accidental uncontrolled lifting of the elevator car that will cause casualties
