Description

Technical Field

[0001] This utility model relates to the field of wind turbine hoisting technology, and in particular to a safety protection device for wind turbine hoisting. Background Technology

[0002] A fan is typically a driven fluid machine that uses input mechanical energy to increase gas pressure and discharge gas. Fans have a wide range of applications, and they convert mechanical energy into gas kinetic energy and pressure energy through components such as impellers to achieve gas transportation or pressure increase.

[0003] When large wind turbines are in use, they are usually installed at a designated height, which requires hoisting operations. During hoisting, a hook is usually attached to the hoisting ring on the wind turbine, and then a lifting device is used to lift the hook to hoist the wind turbine.

[0004] However, when hoisting a wind turbine, simply using a hoisting ring to lift it is usually not convenient to protect the wind turbine from falling. If the hoisting ring is damaged and falls off, the wind turbine will fall directly to the ground, affecting the safety of the wind turbine hoisting. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This utility model provides, for example Figures 1-4 The image shows a safety protection device for hoisting a wind turbine.

[0040] Example 1: Includes a fan 1, a lifting rope 2, and a protective mechanism 3. The bottom of the lifting rope 2 is connected to a hook, which hooks onto a lifting ring to allow for lifting operations on the fan 1. The lifting rope 2 is connected to the lifting equipment. A lifting ring is fixedly connected to the top of the fan 1. The lifting rope 2 is located above the fan 1. The protective mechanism 3 is located on the fan 1 and is used to prevent the fan 1 from falling. The protective mechanism 3 includes a protective belt 31 and a connecting component. The protective belt 31 is conveniently fitted over the outside of the fan 1, thus providing suspension protection for the fan 1's body. When the lifting ring is not detached from the fan 1, the protective belt 31 rests only on the fan 1's body and is not subject to lifting force. If the lifting ring detaches from the fan 1, and the fan 1 falls, the protective belt 31 directly supports and protects the fan 1 to prevent it from falling. The protective belt 31 is fitted over the outside of the fan 1. The connecting component is located on the lifting rope 2 and is used to connect the protective belt 31 to the lifting rope 2.

[0041] Furthermore, the protective mechanism 3 also includes a connecting plate 33 and a limiting plate 312. The connecting plate 33 facilitates the connection of the two ends of the protective belt 31, making it easy to install and use the protective belt 31. The limiting plate 312 helps to keep the protective belt 31 between the two limiting plates 312, so as to prevent the protective belt 31 from sliding freely on the body of the fan 1. The connecting plate 33 is fixedly connected to the end of the protective belt 31, and the limiting plate 312 is fixedly connected to the outside of the fan 1. The protective belt 31 is located between adjacent limiting plates 312.

[0042] Specifically, the connecting components include a connecting rope 32, a connecting post 34, and an assembly post 35. The connecting rope 32 is convenient to connect with the suspension rope 2 to support the connecting post 34. The connecting post 34 is convenient to connect with the connecting plate 33. The assembly post 35 is convenient to allow the right-side connecting plate 33 to be inserted into the connecting post 34 to connect and position the connecting plate 33 for installation and use of the protective belt 31. The connecting rope 32 is fixedly connected to the suspension rope 2. The connecting post 34 is fixedly connected to the bottom of the connecting rope 32. The connecting post 34 is located between adjacent connecting plates 33. The assembly post 35 is fixedly connected to the side of one of the connecting plates 33. The side of the connecting post 34 has an installation groove that mates with the assembly post 35.

[0043] More specifically, the connecting assembly also includes a fixing post 37 and a positioning element. The fixing post 37 facilitates the connection of the left connecting plate 33 to the left connecting plate 33 for connection and fixation. The fixing post 37 is fixedly connected to the other side of the connecting post 34. The outer wall of the fixing post 37 is slidably inserted into another connecting plate 33. The positioning element is located on the connecting post 34 and is used to fix the assembly post 35 to the connecting post 34.

[0044] Specifically, the positioning components include a plug-in post 36, a bearing seat 38, and an anti-detachment rod 39. The plug-in post 36 helps to define the relative position of the assembly post 35 and the connecting post 34, facilitating the assembly of the connecting plate 33. The bearing seat 38 facilitates the sliding of the anti-detachment rod 39, providing sliding support for the anti-detachment rod 39. The anti-detachment rod 39 helps to define the relative position of the bearing seat 38 and the plug-in post 36, thus protecting the plug-in post 36 from detachment. The plug-in post 36 is inserted through the connecting post 34 and the assembly post 35. The bearing seat 38 is fixedly connected to the side of the connecting post 34. The anti-detachment rod 39 is slidably inserted into the interior of the bearing seat 38. The outside of the plug-in post 36 has a circular groove that mates with the anti-detachment rod 39.

[0045] Example 2: Based on Example 1, the positioning component further includes an operating plate 310 and an elastic rope 311. The operating plate 310 facilitates pulling the anti-detachment rod 39 to perform traction operation on the anti-detachment rod 39. The tension of the elastic rope 311 facilitates the operation plate 310 to move the anti-detachment rod 39 and then return it to its original position, making it easy to repeat the operation of the anti-detachment rod 39. The elastic rope 311 can also be checked regularly. The tension of the elastic rope 311 is sufficient to keep the operating plate 310 and the anti-detachment rod 39 stationary. The operating plate 310 is fixedly connected to the end of the anti-detachment rod 39, and the end of the elastic rope 311 is fixedly connected to the operating plate 310. The other end of the elastic rope 311 is embedded in the top of the bearing seat 38.
