Description

An anti-seismic connection device for installing an elevator without a foundation pit

technical field

The invention relates to the technical field of an elevator without a foundation pit, in particular to an anti-seismic connection device for an elevator without a foundation pit.

Background technique

Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. According to the speed, 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). Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings today. In 1852, E.G. Otis of the United States developed a safety elevator for wire rope lifting. In the 1980s, the driving device was further improved, such as the motor driving the winding reel through the worm drive, and the use of a balance weight. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator.

The non-pit elevator is an elevator without a pit. It is usually installed in villas and some small high-rise family elevators. As the elevator running speed increases, the vibration and jitter of the overall elevator will become more serious. In order to ensure the safety of the elevator and the comfort of the car, and to prevent natural earthquake disasters, it is very necessary for the shockproof of the elevator. The stability of the internal installation parts of the elevator shaft is the basis of the entire elevator when it is used. Therefore, in order to solve For this series of problems, we have proposed a non-foundation pit to install an elevator anti-seismic connection device to solve the problem.
