Description

Technical Field

[0001] The present application relates to the technical field of elevator buffer piles, and in particular to an elevator installation buffer pile. Background Art

[0002] Buffer piles are pile structures used to act as buffers during elevator installation. Buffer piles, also known as elevator buffers, are safety devices that can reduce the impact and stop the elevator car or counterweight safely when the elevator car or counterweight exceeds the lowest floor and descends to the bottom pit of the shaft due to some abnormal reason. An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line.

[0003] At present, a Chinese patent announcement with announcement number CN220115996U discloses an elevator installation buffer pile, which includes a buffer body, an insertion rod assembly and an adjusting screw.
