Description

Elevator suspension device with protection effect

Technical Field

The invention relates to the technical field of suspension protection, in particular to an elevator suspension device with a protection effect.

Background

An elevator is a permanent transport device serving a number of specific floors in a building, the cars of which travel in at least two rigid tracks perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical. And the step type escalator also has the step type, and a step plate is arranged on a track to continuously run, and is commonly called as an escalator or a moving sidewalk. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to get in or get out or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. According to the speed, a low-speed elevator, a high-speed elevator and a high-speed elevator can be separated. Hydraulic elevators began to appear in the middle of the 19 th century and were still used in low-rise buildings. In 1852, e.g. otis in the united states developed a safety hoist for wire rope hoisting. In the 80 s, further improvements were made to the drive means, such as motors driving the winding drum via a worm drive, the use of counterweights, etc. At the end of the 19 th century, friction wheel transmission is adopted, and the lifting height of the elevator is greatly increased. At present elevator in-process that uses, in order to prevent that the elevator that the outage arouses from falling, elevator linkage is rotatory through worm drive turbine at the in-process that uses, and when equipment outage, the turbine can receive blockking of worm this moment to can prevent that sheave and turbine from rotating, and then can prevent that the sheave is rotatory to drive wire rope, and then can improve equipment's security.

However, the worm and worm wheel can receive the influence of temperature and dust at driven in-process, at present in order to prevent dust and heat influence worm and worm's normal use, the user can usually add the fan in the protecting box inside and dispel the heat to it, block the dust through the filter layer simultaneously, nevertheless the filter layer can lead to its surface to pile up a large amount of dust at the in-process that keeps off the ash for a long time, and then influences the ventilation efficiency in wind gap, and then lead to worm and worm's heat dissipation to receive the influence, and then lead to equipment life to reduce.
