Embodiment Construction

[0013] The specific structure of the present invention will be further described below in conjunction with the drawings.

[0014] Such as figure 1 As shown, the elevator fall protection device of the present invention includes an array of detection devices 5 and 6 placed in the elevator shaft, a protection device placed at a certain distance below the detection device, and a car buffer 4 placed at the bottom of the shaft . among them:

[0015] The detection device is composed of a transmitting end and a receiving end or a reflecting end, and two or more pairs form a group. According to the height of the elevator hoistway and the distribution of the number of floors, several groups of detecting devices are arranged in the hoistway . In the present invention, a set of detection devices are arranged at the same height of the elevator shaft, of which at least one pair of detection devices 5 is installed on the side of the hall door 2 close to the shaft for detecting falling objects; ...

Abstract

The invention discloses an elevator fall protective device, which comprises a detecting device for detecting a falling object and a protective device, wherein the detecting device is distributed and arranged in a hoistway of an elevator; and the protective device is arranged on side of the hoistway and ejects a protective net to stop and receive the falling object when the detecting device detects that the falling object exists. Compared with the prior art, the elevator fall protective device has more safe and effective protective measures and can effectively reduce accidents caused by fall of people into the hoistway during the operation of the elevator and improve the safety control during the operation of the elevator.

Description

Technical field [0001] The invention relates to the technical field of elevator safety, in particular to a detection and protection device for persons or objects falling in an elevator shaft. Background technique [0002] At present, during the operation of the elevator, when the hall door is opened and the car is not on the current floor, the protection of passengers and nearby operators is to prevent personnel from falling down the shaft by setting up warning signs and simple protective fences by maintenance personnel. The maintenance personnel's own protection is only an improvement in safety awareness, and does not provide substantial protection for people or objects falling into the shaft. When the maintenance personnel are negligent, it is easy to cause themselves or nearby operators to fall down the shaft from the opened hall door, causing casualties. In the elevator industry, there have been many accidents where people accidentally fell into the hoistway from the entrance...
