Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, in particular to an elevator ascending and descending buffer device installed without a foundation pit. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. There are also step-type elevators, with treads installed on crawlers and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment serving specified floors. A vertical elevator has a car that runs between at least two rows of rigid rails that are perpendicular or inclined at an angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use electric escalators regardless of their driving mode. Elevator is a general term for vertical transportation tools in buildings. It can be divided into low-speed elevators (below 4 m / s), fast elevators (4-12 m / s) and high-speed elevators (above 12 m / s) according to speed. Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings. In 1852, EG Otis of the United States developed a safety elevator for wire rope lifting. In the 1980s, the driving device was further improved, such as the electric motor driving the winding drum through a worm gear transmission and the use of a counterweight. At the end of the 19th century, friction wheel transmission was used to greatly increase the lifting height of the elevator.

[0003] With the development of social economy, the use of elevators installed without foundation pits is becoming more and more widespread. However, the elevators installed without foundation pits commonly found on the market often have a certain degree of shaking during operation, which can easily cause the internal personnel to lose their footing and cause injuries. Therefore, in order to solve this series of problems, we have proposed an upward and downward buffer device for elevators installed without foundation pits to solve the problem. Summary of the invention

[0010] Preferably, the distance between the upper electromagnetic pins and the distance between the lower electromagnetic pins on both sides of the derrick track are greater than the width of the car and smaller than the distance between the electromagnets on both sides of the car.
