Step S32, when the height of the installed steel tower column section is higher than the hoisting height of the hoisting system, controlling the driving device of the moving device to synchronously push the slideway to move upwards, and ensuring that the driving devices of all the moving devices on at least one section of steel tower column are not pushed; wherein, the pushing length of the driving device is set as follows: the hanging gripper of the non-pushing moving device moves relatively from the current cross rod of the pushing slideway to the cross rod below the current cross rod, so that the non-pushing moving device bears the slideway, and the driving devices of the rest moving devices retract to finish the upward movement of the frame body;
s33, removing the moving device and the supporting anchors which are positioned at the lowest part of the steel column section, and installing the moving device and the supporting anchors on the newly installed steel column section above;
and step S34, after the frame body is moved up to the lifting height of the lifting system to be higher than the height of the steel column section which is completely installed, repeating the steps S31-S33, and completing the lifting and the installation of the rest steel column sections until the installation of the steel column is completed.
5. The steel column construction process using the construction equipment according to claim 4, further comprising the step of removing the construction equipment applied to the steel column after the steel column is installed, and hoisting the components by a tower crane.
6. The steel column construction process using construction equipment according to claim 4, further comprising the step of controlling the frame body to move down after the steel column is installed, specifically comprising the steps of:
s41, the shell of the second box body is unfixed with the second box body, then the shell is turned 180 degrees and then fixed with the second box body, so that the positions of the upper surface and the lower surface of the hanging head are changed, namely the curved surface of the hanging head faces upwards;
s42, controlling the driving device to retract synchronously, so that the first box body is hung and grabbed to move downwards against the slideway;
S43, turning the shell of the second box body by 180 degrees to enable the horizontal surface of the head part of the corresponding hanging gripper to face upwards; turning the shell of the first box body by 180 degrees to enable the curved surface of the head part corresponding to the hanging grip 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 to enable the curved surface of the head part corresponding to the hanging grip to face upwards; the shell of the first box body is turned 180 degrees, the horizontal surface of the head corresponding to the hanging and grabbing is upwards, so that the state after the step S41 is achieved, and the frame body is moved downwards in a reciprocating mode.
7. The steel column construction process using the construction equipment according to claim 4, wherein the auxiliary cross braces are connected between the steel columns as the installation height of the steel columns increases.
