Description

Four-rail crossing structure of elevator and using method thereof

Technical Field

The invention relates to the technical field of elevators, in particular to an elevator four-rail crossing structure and a using method thereof.

Background

An elevator refers to a permanent transport device serving a number of specific floors within a building with its car running in at least two columns of rigid rails running perpendicular to the horizontal or inclined at an angle of less than 15 ° to the plumb line. There are also steps, where the tread is mounted on a track for continuous running, commonly known as an escalator or a travelator. A stationary lifting device serving a prescribed floor. The vertical lift elevator has a car running between at least two rows of rigid guide rails that are vertical or have an incline angle of less than 15. The size and the structural form of the lift car are convenient for passengers to get in and out or load and unload cargoes. Traditionally, elevators have been known as vertical transportation means within a building, regardless of the manner in which they are driven. The speed can be divided into a low-speed elevator (below 4 m/s), a quick elevator (4-12 m/s) and a high-speed elevator (above 12 m/s). Hydraulic elevators began to appear in the middle of the 19 th century and remain in use on low-rise buildings. In 1852, e.g. ottes in the united states developed a rope lift safety elevator. In the 80 s, the driving device is further improved, such as a motor drives a winding drum through worm transmission, a counterweight is adopted, and the like. At the end of the 19 th century, friction wheel transmission is adopted, so that the lifting height of the elevator is greatly increased.

The elevator car is generally arranged on a four-rail crossing structure to be fixed, however, when the conventional four-rail crossing structure is used, bolts are generally fixed, and the fixed installation of the elevator car applicable to different sizes cannot be adjusted, so that certain limitation is brought to the use of the four-rail crossing structure, and the applicability popularization cannot be carried out.
