[0003] In the existing wind turbine concrete tower, the main types of cables laid are high-voltage cables, control cables, power cables, etc., but the ladder system, high-voltage cable support, control cable support, power cable support, lamp support, etc. are usually separate structures, which not only makes the installation and maintenance process extremely complicated and cumbersome, increases the workload of the staff, but also occupies a large amount of space inside the wind turbine concrete tower, affecting the heat dissipation of various cables; the separated structure also requires more embedded holes to be reserved on the inner wall of the wind turbine concrete tower, increasing the initial construction period and technical difficulty, and affecting the overall strength and stability of the wind turbine concrete tower; the cable part of the support structure design is too complicated, and it is inconvenient to transport, construct and install on site; the cable part of the support structure is located close to the inner wall of the wind turbine concrete tower, and there is a risk of interference with the prestressed steel strands. In addition, if a lift is set up in the wind turbine concrete tower, it is necessary to install a guide rail to assist the operation of the lift. Summary of the invention
