Description
Technical Field
The invention relates to the technical field of wind driven generator tower barrels, in particular to a fixed tower barrel transfer platform.
Background
With the increase of the generating efficiency of the wind turbine, the structural form of the wind power tower is developed towards a newer and more complex direction. The average height of tower structures developed by wind plants is increasing every year. The ultrahigh tower drum has the characteristics of high cost, complex structural form, long service life and the like, so that the requirements on error control during the construction of the structure and safety, applicability and durability during the operation of the structure are stricter. In order for a structure to operate properly, real-time tracking and maintenance of the structure, the performance and the state of equipment must be performed.
Due to the wind tower, the stress and deformation of the concrete-steel tower cylinder and the change of the wind load and the temperature are required to be subjected to long-term health detection from the construction to the use process, so that the evolution conditions of the parameters are accurately and timely recorded and mastered, and the structural durability of the concrete-steel tower cylinder can be judged. Therefore, the sensors inside the tower need to be maintained regularly.
And the collision and abrasion among the prestressed steel strands, the PE protective layer of the cable and the steel casing are often caused by the prior art, so that more serious friction problem and difficult maintenance problem are caused.
Because the sensor and the anchorage device are respectively arranged at different heights of the tower, after the construction hoisting of the tower is completed, the operation and maintenance worker can only reach the relevant height by means of the elevator or the ladder stand after the machine is stopped because the relevant construction hoisting platform is already removed. Not only causes great economic loss, but also has great potential safety hazard. In addition, the method can be used for producing a composite material
1) At present, the existing general construction platform is difficult to take out and inconvenient to detach after the hoisting is finished due to the designed process layout reasons after the tower drum ring piece is hoisted.
2) Because the tower drum adapter section is embedded and the process is complex, a safe and stable construction environment needs to be provided for construction workers in the hoisting process, and the existing general construction platform cannot meet the requirements of the adapter section.
3) The personnel of ascending a height not only at upper and lower in-process and cable discharge in-process, consider the maintenance of later stage fan moreover, the personnel of ascending a height need have a rest midway. However, the ladder stand is too large in distance from the inner wall of the tower, and potential safety hazards exist when the ladder stand leans against the inner wall of the tower for rest.
In order to solve the problem, the application provides a fixed tower section of thick bamboo switching platform.
