Elevator supporting column

Abstract

The invention relates to an elevator supporting column. The supporting column comprises a metal column and elastic rubber columns. A plurality of circular through holes penetrating through the metal column are formed in the metal column, each circular through hole is internally provided with the corresponding elastic rubber column, and the heights of the elastic rubber columns are larger than the height of the metal column. Each elastic rubber column comprises the following components of, by weight, 100 parts of styrene butadiene rubber, 10-30 parts of polyvinyl chloride, 5-15 parts of an aging proof agent, 3-6 parts of an accelerant, 5-15 parts of a flame retardant, 10-30 parts of gel amorphous silica, 10-15 parts of carbon black and 10-30 parts of glass fibers. The supporting column is used for supporting an elevator car body. According to the elevator supporting column, the elastic rubber columns are arranged in the metal column so that when the elevator car body falls to the supporting column, the elastic rubber columns can achieve buffering and damping effects to rapidly decrease the falling speed of the elevator car body, and thus the situation that the elevator car body makes direct and physical contact with the metal column under the high-speed operation state is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a support column of an elevator. Background technique [0002] Van elevators are often used in mid-to-high-rise buildings such as office buildings and residences. When the elevator falls to the bottom, if the elevator car body directly contacts the metal support member, it will generate strong vibration and easily cause damage to the elevator car body. . In order to avoid direct contact between the elevator car body and the metal base, improve the safety of the van elevator and prolong the service life of the van elevator. Therefore, how to design a support column of an elevator with cushioning properties is an urgent problem to be solved in the industry. Contents of the invention [0003] The object of the present invention is to provide a support column of an elevator by avoiding the deficiencies in the prior art. [0004] The object of the present invention is ...
