and S34, after the frame body moves upwards to the lifting system, the lifting height of the lifting system is higher than the height of the installed steel tower column segment, repeating the steps S31-S33, and completing the lifting and installation of the rest steel tower column segment until the installation of the steel tower column is completed.
5. The steel tower construction process using construction equipment according to claim 4, further comprising step S4, after the steel tower is installed, removing the construction equipment applied to the steel tower, and hoisting down the component by a tower crane.
6. The steel tower construction process using construction equipment according to claim 4, further comprising step S4, after the steel tower is installed, controlling the frame body to move down, specifically comprising the steps of:
s41, the shell of the second box body is released from the second box body, and then the shell is fixed with the second box body after being turned for 180 degrees, so that the upper surface and the lower surface of the head of the hanging claw are changed in position, namely the curved surface of the head of the hanging claw faces upwards;
s42, controlling the driving device to retract synchronously, so that the hanging claw of the first box body pushes the slideway to move downwards;
s43, turning the shell of the second box body by 180 degrees, and enabling the horizontal surface of the corresponding head to face upwards; turning the shell of the first box body by 180 degrees, and enabling the curved surface of the head correspondingly hung and grabbed to face upwards; controlling the driving device to lift the first box body;
s44, turning the shell of the second box body by 180 degrees, and enabling the curved surface of the head correspondingly hung and grabbed to face upwards; and (4) turning the shell of the first box body by 180 degrees, namely, enabling the horizontal surface of the corresponding hanging head to face upwards, so as to reach the state after the step S41, and thus, reciprocating to realize the downward movement of the rack body.
7. The steel tower construction process using construction equipment according to claim 4, wherein an auxiliary wale is connected between the steel towers as the installation height of the steel tower rises.
