Description

Technical Field

[0001] The invention relates to the technical field of elevator component processing, in particular to an automatic cleaning machine for an elevator buffer cylinder. Background Art

[0002] Elevator buffers are critical safety devices installed at the bottom of the elevator shaft, forming the elevator system's final physical barrier. Their primary function is to absorb the kinetic energy of the car or counterweight in extreme situations, such as wire rope breakage or insufficient traction. By decelerating and cushioning the car, they prevent it from directly impacting the bottom or top of the shaft.

[0003] The elevator buffer is mainly composed of a cylinder body, a reset pressure block, a lower pressure column, a reset spring, a ring, a first connecting block, a second connecting block, an upper contact and a lower contact. Its core structure is the cylinder body, which serves as the main structure of the buffer. A spring is set on the top outside, and an oil seal is set on the top inside. During the processing, the inner wall of the cylinder body needs to be cleaned. At present, the main cleaning method is semi-manual and semi-automatic. Loading and unloading need to be completed manually, while the cleaning process can be completed by cleaning equipment. This operation is inefficient. In addition, it is difficult to ensure the precise positioning of the cylinder body in the cleaning equipment during manual loading. Deviations in the placement of the cylinder body will cause the cleaning equipment (such as nozzles, brushes, etc.) to be unable to accurately align with the target area on the inner wall of the cylinder body.
