Ladder stand safety protection device on top of tower of wind driven generator

Abstract

The invention discloses a ladder stand safety protection device on the top of a tower of a wind driven generator. The ladder stand safety protection device is arranged beside the upper part of a ladder stand in the top of the tower of the wind driven generator and is characterized by comprising a protection cage hinged to one of side beams of the ladder stand; the lower part of the protection cage is sealed, and the upper part of the protection cage is open; the protection cage comprises a base frame; a guardrail is arranged on the base frame; an opening is formed in one side of the guardrail; and one side, which is open, of the guardrail is fixed on the side beam of the ladder stand through a hinge. The safety protection device is arranged on the side beam, which is about 2m away from the lower part of a yaw platform, of the ladder stand, so that negligence and inertness of people are overcome, protection measures are forcibly taken when working personnel climb up and down a manhole door of the yaw platform on the top of the tower, and a phenomenon that the working personnel accidentally drop is avoided; and the safety protection device is simple in structure, convenient to mount and use and safe.

Description

【Technical field】 [0001] The invention relates to a safety protection device for a climbing ladder at the top of a tower tube of a wind power generator. 【Background technique】 [0002] The tower, the main supporting structure of the wind turbine, is usually more than 60 meters high. To operate and maintain the wind turbine, the staff need to climb up and down the tower from the bottom of the tower along the vertical ladder installed along the wall of the tower, so as to enter and exit the cabin on the top of the tower. Since the maintenance rest platform (i.e. yaw platform) on the top of the tower is usually 1.5 meters high from the top of the tower, the height of the straight climbing ladders on the upper and lower towers is usually less than 1 meter from the top of the platform (because the tower climbing ladder extends out of the platform Too high will interfere with the ladder entering the cabin during yaw rotation). Therefore, when the staff reach the top of the tower ...

AI Technical Summary

Problems solved by technology

Therefore, when the staff reach the top of the tower ladder and have not yet stepped onto the yaw platform, they need to untie the anti-fall safety rope or safety slide rail hanging on the body to climb onto the yaw platform, but at this time they have not climbed onto the yaw platform. The platform staff has untied the safety rope on the ladder. Due to negligence and inertia, there will be a danger of slipping or falling, and the consequences will be unimaginable.
