Embedded type multistage elevator buffer and working method thereof

Abstract

The invention provides an embedded type multistage elevator buffer and a working method thereof. The embedded type multistage elevator buffer and the working method thereof are characterized in that the embedded type multistage elevator buffer comprises a hydraulic oil cylinder bottom plate and a hydraulic oil cylinder arranged on the hydraulic oil cylinder bottom plate, and a second stage plungerwhich can slide in a rise and fall mode along the interior of a hydraulic oil cylinder body and a second stage reset spring located below the second stage plunger are arranged in the hydraulic oil cylinder body in a sealing mode; a first stage plunger which can slide in a rise and fall mode along the interior of a second stage plunger body and a first stage reset spring located below the first stage plunger are arranged in the second stage plunger body in a sealing mode; and inner cavities of the hydraulic oil cylinder, the second stage plunger and the first stage plunger communicate with oneanother, and hydraulic oil is poured into the inner cavities of the hydraulic oil cylinder, the second stage plunger and the first stage plunger. The embedded type multistage elevator buffer has a simple structure and reasonable design, and the technical bottleneck problems of increasing capacity, increasing speeds and achieving high capacity of a passenger elevator are solved without changing abuilding structure of an original shaft bottom pit.

Description

[0001] Technical field: [0002] The invention relates to an embedded multi-stage elevator buffer and its working method. [0003] Background technique: [0004] At present, a large number of buildings waste a lot of time waiting for elevators during the peak period of personnel flow, which greatly reduces the value of the property; capacity-increasing and high-capacity passenger elevators are installed without changing the original shaft building structure, and the number of passengers is more , Faster elevator products, and added new functions to improve the carrying efficiency and reduce the capacity drop caused by misoperation, so that the original vertical transportation capacity was increased by 2-3 times, effectively alleviating the traffic situation in the original building, Increased property value. [0005] The elevator buffer is one of the most important safety components of the elevator. According to the GB7588 "Safety Code for Elevator Manufacturing and Installati...

AI Technical Summary

Problems solved by technology

[0005] The elevator buffer is one of the most important safety components of the elevator. According to the GB7588 "Safety Code for Elevator Manufacturing and Installation", when the elevator running speed ν≥2.0 m / s, it must be equipped with an energy-consuming buffer; The pressure buffer requires that the height of the pit is usually greater than 1.8 meters, and the height of the pit in the original hoistway building structure cannot be changed
