Description

Spring damper for elevator

Technical Field

The utility model relates to an elevator equipment correlation technique field specifically is a spring damper for elevator.

Background

An elevator is a motor-powered vertical lift equipped with a box-like car for use in multi-story buildings for carrying people or cargo. 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. Low-speed elevators, fast elevators and high-speed elevators can be divided according to speed. 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, and the lifting height of the elevator is greatly increased. The elevator adopts a permanent magnet synchronous traction machine as power at the end of the 20 th century. The machine room occupation is greatly reduced, the energy consumption is low, the energy is saved, the efficiency is high, the lifting speed is high, and the like, and the development of real estate to the direction of an ultra-high layer is greatly promoted.

With the rapid development of economy and the continuous promotion of urbanization process in China being the main driving force for increasing elevator demand, historical data regression analysis shows that the relevance of real estate investment and elevator demand is high. The commercial real estate investment acceleration is slowed down under the influence of the regulation and control of national policies, but the construction of 3600 thousands of security rooms in the 'twelve-five' period can increase the demand on the elevator, and meanwhile, the construction of a large number of public infrastructures, energy-saving modification replacement and export can promote the output of the elevator in China. By 2015, the output of the elevators in China is expected to break 75 thousands of elevators per year and is doubled, and the conservative prediction of the increase speed is about 20%. According to the forecast of the Chinese elevator association, the elevator output of China will continue to keep steadily increasing in the coming years, and the annual increase speed is between 15% and 20%. With the continuous development of the technology and the continuous implementation of the policy of energy conservation and emission reduction in China, the proportion of the output of the energy-saving elevator in the total output of the elevator in China is continuously increased.

At present, elevators are more and more commonly used in high-rise buildings, and convenience is provided for people to go upstairs and downstairs.

Along with the development of buildings, elevators are used more and more, and along with the increasing of cases of elevator faults, the elevators often fall down, so that human bodies cannot bear impact force generated by bottoming after the elevators fall down at high speed, and the elevators die.

Safety buffer provides last safety protection's elevator safety device, but its buffering shock attenuation effect of prior art's safety buffer is not good, has the unable condition of avoiding causing the upwards "pitch" phenomenon of lower pulling walking piece because of the vertical buffer spring of side is compressed back rebound fast, and the security of unable assurance equipment needs to design this problem.
