specific Embodiment approach 1

[0052] An energy-absorbing buffer structure for an elevator, comprising several curved shrapnels 1, the several curved shrapnels 1 are evenly distributed and fixedly arranged around the bottom surface of an elevator car, and the central axis of each said curved shrapnel 1 starts from the bottom edge of the car. The edge to the edge of the curved elastic piece 1 away from the bottom edge of the car is in an 'S' shape, and the several curved elastic pieces 1 extend downward from the bottom edge of the car to the central axis of the car and gather together.

[0053] Further, the curved shrapnel 1 includes an arc surface I11 and an arc surface II12, the arc surface I11 is fixedly connected to the bottom edge of the elevator car, the arc surface I11 protrudes toward the central axis of the elevator car, and the arc surface II12 Contrary to the convex direction of the arc surface I11, the arc surface II12 is integrally formed with the arc surface I11.

[0054] Further, the model for...

specific Embodiment approach 2

[0066] An elevator car cage frame includes an elevator car frame 2 and an elevator energy-absorbing buffer structure as described in Embodiment 1, and the elevator energy-absorbing buffer structure is fixedly arranged at the bottom edge of the elevator car frame 2 .

specific Embodiment approach 3

[0067] A method for preparing the elevator car cage described in Embodiment 2, comprising the following steps:

[0068] Step 1, making the elevator car frame blank: the elevator car frame tooling inner mold 2 is a cube frame, and the cross-section of each prism forming the cube frame is the shape of three steps. Wrap several layers of continuous fiber narrow strips on the surface and plane to obtain the elevator car frame blank. The cross-section of each prism that makes up the elevator car frame blank is 'L'-shaped. The advantages of the 'L'-shaped prism are strength. The second is to facilitate the subsequent placement of the wall panels of the elevator car;

[0069] Step 2. Making the lifting bracket blank: the upper surface, the lower surface and the middle part of the two side walls of the elevator car frame tooling inner mold 2 are fixedly provided with two mutually parallel baffles 31, forming two groups of mutually parallel lifting brackets. The inner mold 3 of the br...

Abstract

The invention relates to an elevator energy-absorbing and buffering structure, an integrated elevator car cage frame and a preparation method thereof, and belongs to the technical field of elevator manufacturing, and the elevator energy-absorbing and buffering structure is characterized by comprising a plurality of curved-surface elastic pieces which are evenly distributed and fixedly arranged on the periphery of the bottom face of an elevator car, and the curved-surface elastic pieces are arranged on the periphery of the bottom face of the elevator car. The cross section of each curved-surface elastic piece is in an S shape from the bottom edge of the elevator car to the longitudinal axis of the edge, away from the bottom edge of the elevator car, of the curved-surface elastic piece, and the multiple curved-surface elastic pieces extend downwards from the bottom edge of the elevator car to the central axis of the lift car and are gathered together. Compared with a traditional elevator buffer, the elevator energy-absorbing buffer structural structure with the damage-resistant and non-rebounding car bottom has the advantages that the manufacturing is free of pollution, and electric energy is saved; the installation is simple, and weather resistance is high; the effective buffering distance is long, and the occupied distance is saved by 70%; when the elevator car falls to the bottom, no vibration or rebound exists; and the whole energy-absorbing and buffering structural member plays a role of a flow guide cover.

Description

technical field [0001] The invention belongs to the technical field of elevator manufacturing, and in particular relates to an elevator energy-absorbing buffer structure, an integrated elevator car cage and a preparation method thereof. Background technique [0002] Elevators have become necessary facilities in civil buildings, shopping malls, stations, airports and other places, bringing convenience to people's travel. However, the existing elevator cars and buffers mainly have the following problems: the weight of the metal car, high failure rate, high energy consumption, and high maintenance costs; large size errors in on-site assembly, resulting in large vibration and noise; poor energy absorption effect of the buffer , the installation and construction conditions are complicated, the price is high, and there are many hidden dangers of water return from the bottom pit; it cannot meet the needs of adding elevators to old buildings, and the construction is slow, resulting ...
