Description

Elevator wire rope strength test detection device

Technical Field

The utility model relates to a detection device, in particular to an elevator steel wire rope strength detection device.

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. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. 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 access 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, the elevator can be divided into a low-speed elevator (below 4 m/s), a high-speed elevator (4-12 m/s) and a high-speed elevator (above 12 m/s). The hydraulic elevator begins to appear in the middle of the 19 th century and is still applied to low-rise buildings until now. In 1852, e.g. austs 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, the lifting height of an elevator is greatly increased, elevator steel wire ropes are used as steel wire ropes on the elevator as the name suggests, the most used small manned elevators are small-sized residential buildings, and the specification and the model of the elevator steel wire ropes are generally 8 × 19S + FC-8mm and 8 × 19S + FC-10mm in residential districts.

Elevator wire rope need examine elevator wire rope intensity after production and detect, but current elevator wire rope examines test device and does not do not by protect function, can appear stretching out the phenomenon of breaking when examining thinner elevator wire rope, has the risk that causes the injury to the staff.
