Description

Technical Field

[0001] The utility model relates to the technical field of climbing frames, in particular to a climbing frame for repairing wind power generation equipment with a safety protection function. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free renewable energy source that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity. Wind power generation equipment is equipment that uses wind energy to generate electricity. It is characterized by clean energy, green and unlimited natural resources. Wind is one of the pollution-free energy sources. And it is inexhaustible. For coastal islands, grassland pastoral areas, mountainous areas and plateau areas that lack water, fuel and transportation, it is very suitable to use wind power generation according to local conditions, and there is a lot of room for development. Offshore wind power is an important field for the development of renewable energy, an important force to promote the advancement of wind power technology and industrial upgrading, and an important measure to promote the adjustment of energy structure.

[0003] For example, the authorization announcement number CN218293469U discloses a climbing frame for repairing wind power generation equipment with a safety protection function, including a climbing ladder, the front and back of the climbing ladder are provided with track grooves, the inner wall of the track groove is respectively slidably connected with a first track block and a second track block, the front of the first track block is provided with a groove, the inner wall of the groove is rotatably connected with a baffle, and the upper surface of the first track block is fixedly connected with a connecting plate. The climbing frame for repairing wind power generation equipment with a safety protection function is fixedly connected with a connecting ring using an external safety rope. When the construction personnel are climbing, the safety rope can be used to pull the first track block to slide upward, and the first track block is set on both sides of the climbing ladder, thereby increasing the climbing space of the climbing ladder. When the construction personnel climb and fall, the pulling rope can drive the baffle to move downward, so that the baffle rotates and contacts with the pedal of the climbing ladder, thereby limiting the first track block from continuing to move downward, protecting the safety of the staff. However, it is not convenient for protection and buffering during use. For this reason, we propose a climbing frame for repairing wind power generation equipment with safety protection function.
