Technical Field
The invention relates to the technical field of elevator braking, in particular to an anti-corrosion safety tongs for an elevator.
Background
The elevator is a vertical elevator powered by an electric motor and is provided with a box-shaped nacelle for use in multi-story buildings for taking persons or carrying goods. 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 that travels between at least two vertical rows of rigid guide rails. 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 1 m/s), a quick elevator (1-2 m/s) and a high-speed elevator (above 2 m/s). Hydraulic elevators began to appear in the middle of the 19 th century and have been used in low-rise buildings to date. 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.
However, when the elevator is lifted too fast, potential safety hazards easily occur, so that the technical problem needs to be solved.
