The invention discloses a safety device for protecting a tower crane worker to get on and off a tower crane. The safety device comprises a bottom frame, a first clamping arm and a second clamping arm.The first clamping arm and the second clamping arm are arranged on the bottom frame and can enable a safety belt to be tied. The first clamping arm and the second clamping arm are arranged in pairs and configured into a steel frame for clamping the tower crane. A driving wheel abutting against the steel frame, a control board, a motor and an acceleration sensor are arranged on the bottom frame, the driving wheel is connected to an output shaft of the motor, and the acceleration sensor is configured to detect the vector direction of the acceleration of the safety device, control the motor to drive the driving wheel to rotate when the vector direction of the acceleration is upward in order to enable the safety device to climb along the steel frame and switch off motor drive or control the motor to reversely rotate when the vector direction of the acceleration is downward. By means of the safety device for protecting the tower crane worker to get on and off the tower crane, personal safety of the worker can be protected.

    本发明公开了一种保护塔吊作业人员上下塔吊的安全装置,包括底架和设置在所述底架上可供安全带系缚的第一夹臂和第二夹臂,所述第一夹臂和所述第二夹臂均成对设置且构造为夹持塔吊的钢架;所述底架上设置有与所述钢架抵接的主动轮,以及控制板、电机和加速度传感器,所述主动轮连接在所述电机的输出轴上,所述加速度传感器配置为检测所述安全装置的加速度的矢量方向,并在加速度的矢量方向向上时控制所述电机驱动所述主动轮转动以使所述安全装置沿所述钢架爬升,而在所述加速度的矢量方向向下时关闭电机驱动或控制所述电机反转。本发明的一种保护塔吊作业人员上下塔吊的安全装置,可以保护作业人员的人身安全。
