Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of elevator emergency rescue, and particularly relates to an elevator emergency rescue system. Background Art
[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car moves on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. There are also step-type ones, where the tread plates are installed on the tracks and run continuously, commonly known as escalators or moving sidewalks. It is a fixed lifting device that serves the specified floors. A vertical lift elevator has a car that moves between at least two vertical or inclined rigid guide rails with an inclination angle less than 15°. The car size and structural form facilitate passengers to enter and exit or load and unload goods. Conventionally, regardless of its driving method, an elevator is generally referred to as a vertical transportation tool in a building. It can be divided into low-speed elevators (below 4 m / s), fast elevators (4 - 12 m / s), and high-speed elevators (above 12 m / s) according to speed. Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings today. In 1852, E.G. Otis in the United States developed a safety lift with wire rope hoisting. In the 1980s, the drive device was further improved, such as the motor driving the winding drum through worm drive and using a counterweight, etc. At the end of the 19th century, friction wheel drive was adopted, greatly increasing the lifting height of the elevator. Although the power technology of the elevator is constantly improving and developing, its safety performance has never been perfectly guaranteed.

The plurality of protective structures 8 are distributed in an equidistant array inside the mounting frame 9. The mounting frame 9 is provided with lighting lamps 10. The plurality of lighting lamps 10 are respectively arranged between the plurality of protective structures 8. The protective structure 8 includes a mounting cover 11. A baffle 12 is placed at the bottom end of the mounting cover 11. A hinge 13 is provided at one end of the baffle 12. The baffle 12 is hinged to the inner side of the mounting cover 11 through the hinge 13. A controller 16 is provided inside the mounting cover 11. , and the bottom side of the controller 16 adsorbs the end of the baffle 12 away from the hinge 13, a handle 14 is placed on the upward working surface of the baffle 12, a connecting rope 15 is provided on the handle 14, and the end of the connecting rope 15 away from the handle 14 extends out of the top of the mounting cover 11, a buffer structure 4 is provided at the top of the car 1, the buffer structure 4 includes a mounting frame 5, the mounting frame 5 is fixed to the top of the car 1, and the bottom end of the mounting frame 5 is covered on the outside of the mounting frame 9, a buffer spring 6 is provided inside the mounting frame 5, and the buffer spring 6 is connected and fixed to the end of the connecting rope 15 away from the handle 14, the number of multiple buffer springs 6 is the same as the number of protective structures 8, and the multiple buffer springs 6 are all arranged above the multiple protective structures 8, a traction rod 2 is provided at the top of the car 1, and multiple traction rods 2 are equidistantly arrayed at the top of the car 1, and a traction ring 3 is provided at the top of the traction rod 2.
[0025] The working principle and use process of the present invention:
[0026] When in use: when the elevator car 1 falls out of control during operation, the controller 16 in the protective structure 8 provided at the top of the elevator car 1 can sense the abnormal acceleration of the elevator. When it is detected that the elevator is in a dangerous state, the protective mechanism is triggered quickly. The controller 16 cancels the adsorption of the baffle 12 and opens one end of the baffle 12 downward with the hinge 13 as a fulcrum, so that the handle 14 and the connecting rope 15 inside the mounting cover 11 fall. In an emergency, the passengers can hold the handle 14 and pull their bodies upward to leave the ground. When the elevator car 1 contacts the ground, the passengers buffer the falling force through the buffer spring 6 connected to the connecting rope 15 to eliminate the descending potential energy. When the elevator car 1 collides with the ground, the passengers are suspended in the air, and the rapidly descending body does not contact the ground, which plays a certain safety protection role and effectively protects the passengers.
