Protective device for construction hoist cage

Abstract

The invention discloses a protective device for a construction hoist cage. The protective device comprises a frame body, lifting doors are arranged on the two sides of the frame body, a bottom frame is fixedly mounted below the frame body, a bottom plate is fixedly mounted below the bottom frame, four safety airbags are symmetrically placed on the upper portion of the bottom plate, a first separation frame and a second separation frame are further fixedly mounted on the upper portion of the bottom plate, the first separation frame and the second separation frame intersect vertically, a threaded rod is arranged at the center of the intersection of the first separation frame and the second separation frame, a driving device is arranged at the bottom of the threaded rod, a sleeve is in threaded connection with the upper portion of the threaded rod, a supporting plate is arranged on the upper portion of the sleeve, the sleeve and the supporting plate are fixedly connected, and the supporting plate is connected with the frame body through a sliding device. According to the protective device, the supporting plate and a passenger on the supporting plate can be quickly jacked up within a short time of falling, so that the supporting plate and the passenger are not in direct contact with the safety air bags below the supporting plate, and more serious injury caused by impact force at the moment that the safety air bags are bounced up is avoided.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to a protective device for a construction elevator cage. Background technique [0002] Construction elevators are also called construction elevators for buildings, and they can also be used as outdoor elevators and hoisting cages on construction sites. Construction elevators are mainly used in various types of urban high-rise and super high-rise buildings, because it is very difficult for such building heights to use well-shaped frames and gantry frames to complete operations. It is a manned and cargo-carrying construction machine often used in construction, mainly used for interior and exterior decoration of high-rise buildings, construction of bridges, chimneys and other buildings. The construction hoist is a kind of dangerous equipment, which is easy to cause serious casualties. Even if there are multiple safety devices on the construction elevator, it is impossi...
