Construction hoist cage with automatic opening and closing doors

Abstract

The invention discloses a construction lift cage with an automatically opened-closed door, which has the advantages that the door of the lift cage is opened and closed rapidly and is easy to lock, and the energy consumption is less. The construction lift cage comprises a lift cage body, an upwards-going door and a downward-going door, wherein the upwards-going door and the downwards-going door are arranged on the lift cage body; the lift cage also comprises a driving motor, a winding drum, an upwards-going door lifting rope for opening and closing the upwards-going door, and a downwards-going door lifting rope for opening and closing the downwards-going door; the driving motor is mounted on the lift cage body; the winding drum is mounted on the driving motor; the upwards-going door lifting rope is arranged at one end of the winding drum in a winding manner, and the free end of the upwards-going door lifting rope is connected with the upwards-going door; the downwards-going door lifting rope is arranged at the other end of the winding drum in a winding manner, and the free end of the downwards-going door lifting rope is connected with the downwards-going door; the winding direction of downwards-going door lifting rope on the winding drum is opposite to that of the upwards-going door lifting rope on the winding drum. The upwards-going door and the downwards-going door are arranged, so that the lifting stroke or the declining stroke of the lift cage is shorter, the lift cage can be rapidly opened and closed, and the energy consumption is less. The lifting ropes are arranged oppositely, so that torque parts are offset; the upwards-going door and the downwards-going door are interlocked, so that the driving energy consumption is less.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to a construction hoist cage with an automatic opening and closing door. Background technique [0002] The construction hoist cage is one of the important components of the construction hoist, which is used to transport goods and materials in the construction site to the corresponding floors. The cage doors of the construction hoist used in the field of construction machinery are opened and closed up and down, and are usually divided into double-door cages with uplink doors and downlink doors and single-door cages with only a single row of cage doors. . In the existing construction hoist cage with uplink doors and downlink doors, the opening and closing of the uplink doors and downlink doors are manually controlled, and the uplink doors and downlink doors in the open and closed state cannot be locked. The upper door or lower door may open the cage, resulting in th...

AI Technical Summary

Problems solved by technology

In the existing construction hoist cage with uplink doors and downlink doors, the opening and closing of the uplink doors and downlink doors are manually controlled, and the uplink doors and downlink doors in the open and closed state cannot be locked. The upper or lower door may open the cage, causing people or objects in the cage to fall

And the existing construction hoist cage with single row cage door controls the opening and closing of the cage door through the hoist, but the cage door of the single door cage has a long lifting stroke, it takes a long time to open the cage door and it is not easy after lifting lock; in addition, the winch consumes more energy when the single-row cage is opened and closed
