Abstract: A modular lifting apparatus includes a vehicle body assembly and a drive control assembly. The vehicle body assembly includes a vehicle body and a pedal component, and the pedal component is connected to the vehicle body. The drive control assembly is disposed on the vehicle body, and includes a control component, a drive component and an auxiliary guide component. The control component is connected to the drive component. The drive component and the auxiliary guide component are used to cooperate with a guide body to allow the vehicle body to move in an extension direction of the guide body.

Abstract: A lifting equipment includes a guide rail; a climbing assistant, suitable for ascending and descending along the rail, said climbing assistant having a carriage and a first anti-fall device installed between the said carriage and the said guide rail, and the said first anti-fall device being capable of locking onto the said guide rail when the said carriage experiences weightlessness; a second anti-fall device for installation between the said guide rail and the personnel working on the said carriage, and the said second anti-fall device being capable of locking onto the same guide rail as the said climbing assistant when the personnel on the said carriage become weightless. The first anti-fall device used for the climbing assistant and the second anti-fall device for the personnel are installed on the same guide rail, and allowing the guide rail to be installed in the most optimal position.

Abstract: A cover plate assembly, a wind power tower tube, and a wind turbine. The cover plate assembly comprises: a drive component, comprising a swing rod (6) provided with a first limiting component (3); and a cover plate (8), suitable for rotating between a first position and a second position along with rotation of the swing rod (6), the cover plate (8) being provided with a guide component (4), and the guide component (4) moving along the swing rod (6) in a swinging process of the swing rod (6). At the second position, the guide component (4) is in limiting fit with the first limiting component (3), so as to limit the swing rod (6) to drive the cover plate (8) to move back towards the first position; and when the cover plate (8) rotates towards the second position, matching between the first limiting component (3) and the guide component (4) can prevent the cover plate (8) from continuing rotating.
