Problems solved by technology

[0002] The elevator relies on the retraction and release of the rope to realize the longitudinal movement of the elevator car, but when the rope on the elevator car is disconnected, it will make the elevator car fall freely and land until the elevator car will land on the first floor. People inside the elevator car may be injured during the fall

Embodiment 1

[0020] see Figure 1-4 , a high-rise elevator broken rope safety protection device, comprising an elevator shaft 1, an elevator car 2 and a protection structure, the elevator shaft 1 is provided with an elevator car 2, and the elevator car 2 is provided with a protection structure, the protection structure Including an upper traction structure, a bottom buffer structure, a side buffer structure and a starting end support structure, the elevator shaft 1 is provided with an upper traction structure, the output end of the upper traction structure is provided with an elevator car 2, and the bottom of the elevator car 2 is provided. A bottom buffer structure is provided, the side of the bottom buffer structure is provided with a side buffer structure, and the bottom end of the elevator shaft 1 is provided with a starting end support structure. First, the elevator car 2 is pulled by the upper traction structure, and at the same time, the elevator car 2 is supported and protected by ...

Embodiment 2

[0027] Compared with Embodiment 1, the improvement of this embodiment is that a support groove is provided below the rotating groove, a push hydraulic cylinder 7 is fixed on the side of the support groove, and a push plate is fixed on the side of the push hydraulic cylinder 7 8. An intermediate hydraulic cylinder 9 is fixed on the push plate 8, and a support plate 6 is fixed at the end of the intermediate hydraulic cylinder 9. When the eccentric wheel 5 supports the elevator car 2, the pushing hydraulic cylinder 7 is used to push the pushing plate 8, and the intermediate hydraulic cylinder 9 is used to push the supporting plate 6, so that the supporting plate 6 moves upward, so that the bottom of the eccentric wheel 5 can be supported. , making the device more stable and safer.

[0028] The working principle of the present invention is as follows: the top driving roller 15 is driven by the first power device, while the middle driving roller 14 is driven by the second power dev...

Abstract

The high-rise elevator rope breakage safety protection device comprises an elevator shaft, an elevator car and a protection structure, and the protection structure comprises an upper traction structure, a bottom buffering structure, a side edge buffering structure and a starting end supporting structure. The upper traction structure comprises side edge fixing seats, side edge traction ropes, guide rollers, top driving rollers, middle driving rollers, middle protection ropes and middle fixing seats, and the side edge traction ropes and the middle protection ropes are arranged, so that when the side edge traction ropes are broken, the middle protection ropes can be used for protecting the elevator car; the device can stably fall, and damage caused by free falling motion is avoided; and a side edge buffering structure is arranged on the device, so that side edge buffering can be carried out when the power of the middle protection rope is unstable, and it is guaranteed that the elevator car descends more stably.

Description

technical field [0001] The invention relates to a protection device, in particular to a high-rise elevator broken rope safety protection device. Background technique [0002] The elevator relies on the retraction and retraction of the rope to realize the longitudinal movement of the elevator car, but when the rope on the elevator car is disconnected, it will make the elevator car free-fall motion to descend, until the elevator car will descend to the first floor, in free The fall may cause injury to persons inside the elevator car. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a high-rise elevator broken rope safety protection device to solve the above-mentioned problems in the background art. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A high-rise elevator broken rope safety protection device, comprising an elevator shaft, an elevator car and a protection structur...
