Technical Field
[0001] This utility model relates to the field of wind turbine tower platform technology, specifically a wind turbine tower platform with a concealed handrail. Background Technology
[0002] As an important component of clean energy, wind power generation has been widely used globally in recent years. Wind power generation technology mainly relies on horizontal axis wind turbines, whose basic structure includes components such as blades, hubs, gearboxes, generators, and towers. To facilitate subsequent maintenance, tower platforms are often installed on the surface of the tower. Existing tower platforms mostly consist of a base and handrails. The base is located above the load-bearing frame on the outer surface of the tower, and the handrails prevent people from falling. For convenient transportation, the handrails of the tower platform are often divided into folding or detachable types. Folding handrails can be directly stacked inside the base to form a whole. Detachable handrails can be connected to the base through external connectors and are often removed and transported separately from the base during transportation. In traditional folding handrail tower platforms, the stacked handrails are prone to bending and deformation under pressure during transportation. Detachable handrail tower platforms require the handrails to be transported separately from the base, which is inconvenient for transportation and also prone to parts loss. Therefore, we propose a wind power tower platform with concealed handrails. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a wind turbine tower platform with a hidden handrail. The handrail can be quickly disassembled and stored. When stored, the handrail is located inside the base, so it will not be deformed by pressure and is also easy to transport. This can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower platform with a concealed handrail, including a tower, a base is provided at the center of the front side of the outer surface of the tower, sleeves are provided around the upper end of the base, handrails are provided at the upper end of the sleeves, and a disassembly and assembly mechanism is also included.

The working principle of the wind turbine tower platform with concealed handrail provided by this utility model is as follows: When transporting the wind turbine tower platform, in order to avoid damage to the handrail 4 affecting the transportation, it needs to be stored first. Reverse the connecting bolt 564 to separate the connecting bolt 564 from the connecting hole 563. At this time, the connecting piece 562 is not restricted and separates from the handrail 4 located on the left and right sides. Reverse the limiting bolt 59 to separate the limiting bolt 59 from the limiting hole 58. At this time, the rotating ring 53 is not restricted. Rotate the rotating ring 53 180 degrees so that the limiting piece 54 forms a vertically adjacent protrusion 52. When misaligned, the protruding piece 52 is no longer under force, and the spring 8 expands, causing the sliding rod 51 to move towards the side closer to the middle of the sleeve 3. The sliding rod 51 is pulled out from the corresponding insertion hole 55 and retracted into the sleeve 3, separating the entire handrail 4 from the base 2. Then, the connecting bracket 561 is deflected, causing the connecting piece 562 to fit against the corresponding fixing post 565. The connecting bolt 564 is rotated forward, causing the connecting bolt 564 to be threaded into the inner wall of the corresponding connecting hole 563. The connecting bracket 561 is fixed to the handrails 4 located on the front and rear sides. Then, the handrail 4 located on the front side is slid into the two upper partitions 5. Between 72, slide the rear handrail 4 between the two lower partitions 572, slide the left handrail 4 between the two partitions 574 on the left side, and slide the right handrail 4 between the two partitions 574 on the right side, until the sliding rods 51 on both the front and rear sides are aligned with the first fixing groove 571, and the sliding rods 51 on both the left and right sides are aligned with the second fixing groove 573. At this time, push the protrusion 52 outward, the spring 8 is compressed, and the sliding rod 51 that is laterally adjacent to the first fixing groove 571 is inserted into the interior of the first fixing groove 571 and the second fixing groove 573. 3. The longitudinally adjacent sliding rods 51 are inserted into the fixed groove 573. Then, the rotating ring 53 is rotated 180 degrees, and the limiting piece 54 also rotates and fits together with the corresponding protrusion 52 to ensure that the sliding rods 51 will not retract into the sleeve 3. Then, the limiting bolt 59 is rotated forward so that the limiting bolt 59 is threadedly connected to the inner wall of the corresponding limiting hole 58. At this time, the four handrails 4 are all hidden and fixed inside the base 2. During transportation, the handrails 4 are located inside the base 2 and will not be squeezed. The base 2 and the handrails 4 form a whole, which facilitates the transportation of the wind power tower platform.
