Problems solved by technology

[0002] With the aging of elevators and the irresponsibility of many manufacturers, we often hear reports that elevators malfunction and fall freely, causing the death of people inside the elevator or opening the elevator door, but the elevator does not arrive, causing people to fall and die.
However, most manufacturers have done protection for the safety of the bottom of the elevator in advance, so it can be seen that those protections have no effect

Embodiment 1

[0035] A high-safety elevator, comprising a shaft 1 and a car 2, the inner bottom of the shaft is provided with an arched buffer plate 3 that arches upwards, and a buffer airbag 4 is placed on the upper surface of the arched buffer plate, and the car A plurality of buffer rubber strips 5 are evenly distributed on the bottom, and both ends of the arched buffer plate are connected to the bottom of the hoistway through arch plate expansion offset components.

[0036] The arch plate expansion counteracting part includes a slide track track plate 6 fixed at the bottom of the hoistway and having a track groove 61, and an arch plate integrally connected to the outer sides of both ends of the arch buffer plate and set in the track groove Shrink slide bar 31, the right-angle flap 32 that is fixedly connected on described arched buffer plate and slideway track groove plate and the buffer spring 7 that both ends are connected between the side of right-angle flap and hoistway inner wall. ...

Embodiment 2

[0040]The difference from the above embodiment is that the rail groove plate of the slideway is provided with a plurality of track grooves perpendicular to the two sides of the arched buffer plate, and the retractable slide bars of the arch plate are adapted to the track grooves. The two ends of the shrinking slide bar of the arch plate exceed the two sides of the arched buffer plate, and the right-angled folded plate and the inner wall surface of the well are correspondingly provided with two ends of the buffer spring. Limiting guide post 71.

[0041] The cooperation of the right-angle folding plate, the limit guide post and the buffer spring ensures the stable cooperation between the buffer spring and the arch plate, improves the effectiveness and order of the buffer, and ensures the stability of the structure.

Embodiment 3

[0043] The difference from the above-mentioned embodiment is that the buffer airbag includes a main bladder 41 at the top and several support leg bladders 42 connected to the bottom of the main bladder.

[0044] The foot capsules are divided into two groups symmetrically arranged on both sides of the symmetrical center on the top of the arched buffer plate, and each set of foot capsules includes at least two rows that gradually lengthen from the symmetrical center of the arched buffer plate top to the inner wall of the hoistway. Columns of leg capsules, each column has at least two leg capsules.

[0045] Through the setting of the foot capsule, it is ensured that the entire cushioning airbag is matched with the arch plate, and the force on the bottom of the cushion airbag is balanced, and the force surface at the bottom will not be too small due to the arch plate, and the pressure is strong and vulnerable, and the support foot capsule is in accordance with the corresponding arc...

Abstract

The invention belongs to the field of elevators and particularly relates to a high-safety lifting elevator. The high-safety lifting elevator comprises a shaft and an elevator car. An arch-shaped buffer plate is arranged at the bottom in the shaft. An upper buffer air bag is arranged on the upper surface of the arch-shaped buffer plate. Multiple buffer rubber strips are evenly distributed at the bottom of the elevator car. The two ends of the arch-shaped buffer plate are connected with the bottom of the shaft through arch plate unfolding offset components. Each arch plate unfolding offset component comprises a slideway track groove plate fixedly arranged at the bottom of the shaft and provided with track grooves, arch plate contracting sliding strips integrally connected to the outer sides of the two ends of the arch-shaped buffer plate and arranged in the track grooves, a right-angled folding plate fixedly connected to the arch-shaped buffer plate and the slideway track groove plate and a buffer spring with the two ends connected between the side portion of the right-angled folding plate and the inner side wall of the shaft. According to the high-safety lifting elevator, arch plates cannot move freely due to the arch plate unfolding offset components and only can contract in the two-end direction, it can be guaranteed that the arch plates are buffered to the best effect, the buffer capacity of the arch plates is improved due to the buffer springs, the buffer effect is improved, and the protection function on the arch plates is played.

Description

technical field [0001] The invention belongs to the field of elevators, and in particular relates to a high-safety elevator. Background technique [0002] With the aging of elevators and the irresponsibility of many manufacturers, we often hear some reports that the elevator malfunctions and falls freely, causing the death of people in the elevator or opening the elevator door, but the elevator does not arrive, causing people to fall and die. . However, the safety of the bottom of the elevator has been protected by most manufacturers in advance, so it can be seen that those protections have no effect. Contents of the invention [0003] The object of the present invention is to provide a high-safety elevator in order to solve the above problems. [0004] Above-mentioned technical purpose of the present invention is achieved through the following technical solutions: [0005] A high-safety elevator, including a shaft and a car, the inner bottom of the shaft is provided wi...
