A kind of elevator structure with multi-stage bottom connection buffer function

Abstract

The invention relates to the technical field of elevators, and discloses an elevator structure with a multi-stage bottom connection buffer function, which includes a bottom plate, an underframe installed on the outer side of the upper end of the bottom plate, and a top plate installed on the top of the bottom frame, and a car is connected to the upper end of the bottom plate through several buffer mechanisms , the top of the car is equipped with a protective frame, the top of the protective frame is fixedly connected with a top plate, the protective airbag is installed inside the protective frame, a number of buffer tubes are installed at the top of the car, the buffer plate is installed inside the buffer tube, and the buffer column is installed at the bottom of the buffer plate , an air guide tube is communicated between the inside of the buffer cylinder at the lower end of the buffer plate and the protective air bag. The present invention realizes the effective buffering effect on the bottom of the elevator, and at the same time sets a protective airbag and a buffering cylinder on the top of the car to realize the linkage buffering effect of the elevator car and the passengers inside the elevator, and the whole elevator structure can realize multi-stage buffering, which is practical Strong, high security.

Description

Technical field [0001] The present invention relates to the field of elevator technologies, in particular a elevator structure having a multi-stage underwater buffer. Background technique [0002] The elevator refers to a permanent transportation device that serves several specific floors serving in the building. There are also steps, step panels are running continuously on the track, commonly known as escalator or automatic sidewalk. Serve the fixed lifting equipment for the predetermined floor. The vertically liter elevator has a car that operates between the at least two columns perpendicular or the tilt angle is less than 15 °. The car size and structural form facilitates passengers into or loading and unloading. Regardless of its driving mode, the elevator is used as the general story of vertical transportation tools in the building. Press the speed of low speed elevator (4 m / s), fast elevator 4 to 12 m / s) and high speed elevators (12 m / sec or more). [0003] In genera...

Problems solved by technology

[0003] General building all can be equipped with at least one elevator, and there will be the danger of falling when the elevator is running. In the prior art, an elastic buffer device is generally arranged at the bottom of the elevator shaft. When the elevator falls, it will be buffered by the elastic buffer device of the elevator shaft. This buffer mechanism is generally buffered by a spring, a high-performance elastic telescopic rod or an air bag. The manufacturing precision of the above-mentioned buffer mechanism is very high, which increases the manufacturing cost, and the buffer effect is not ideal at the same time.

[0004] Chinese patent (publication number: CN210064822U) discloses a kind of elevator buffer device with safe shock absorbing function, including buffer device body and first fixed thread column, the bottom of the buffer device body is provided with a shock absorbing mechanism, the buffer device The main body and the shock absorbing mechanism are fixedly connected through the first fixed threaded column. The shock absorbing mechanism includes a fixed seat, an elastic sheet and a mounting base. The bottom of the fixed seat is fixed with an elastic sheet, and the elastic sheet is far away from There is an installation base on the side. Although this device can effectively buffer the passengers inside the elevator within a certain range, in actual use, the effect is not ideal only by relying on the shock absorption at the bottom to achieve independent buffering. Therefore, further research is still needed. improvement of
