An elevator fall protection device

Abstract

An elevator anti-falling protection device comprises a hoistway, a landing door opening arranged in front of the hoistway and an elevator cage, wherein two supporting rods are vertically arranged on the front side of the inner wall of the hoistway, the lower ends of the supporting rods are hinged to the inner wall of the hoistway respectively through hinge seats, two cross rods are hinged to the inner side of each supporting frame, the cross rods on the two sides correspond to one another in position, vertical rods are arranged between the two cross rods on the same side, and the upper end andthe lower end of each vertical rod are respectively hinged to the ends, far away from the corresponding supporting rod, of the corresponding cross rods on the same side. The elevator anti-falling protection device has the function of preventing people and goods from falling into the hoistway from the landing door opening during normal operation of an elevator and can be used as an anti-falling device during construction and maintenance of the hoistway. The opening and closing function of the elevator anti-falling protection device does not need external power during operation of the elevator,and the elevator anti-falling protection device is suitable for being used as an anti-falling protection device of a construction elevator.

Description

technical field [0001] The invention belongs to the field of construction elevator safety protection, in particular to an elevator anti-fall protection device. Background technique [0002] Construction elevator is an indispensable vertical transportation tool during high-rise building construction. The car door and landing door of existing construction elevators mostly use sliding doors or fence doors with manual switches. If the anti-fall door is closed in time, there is a risk of falling from the opening of the anti-fall door. In addition, when maintenance and construction are required in the shaft, it is also necessary to set up anti-fall devices on the upper and lower sides of the work area for safety. An easy-to-use elevator anti-fall Fall protection device. Contents of the invention [0003] The invention provides an elevator fall protection device to solve the defects in the prior art. [0004] The present invention is achieved through the following technical sol...
