Adjustable guide wheel structure of sleeve frame

The invention discloses an adjustable guide wheel structure of a sleeve frame. The adjustable guide wheel structure comprises a sleeve frame main body, guide wheels and a mounting support, wherein the mounting support is detachably mounted on the sleeve frame main body; the guide wheels are detachably mounted on the mounting support; and the positions of the guide wheels can be adjusted through adjusting the mounting state of the mounting support, so that clearances between the guide wheels and a tower body during assembly meet the assembly requirement. According to the adjustable guide wheel structure, the guide wheels are mounted on the sleeve frame main body through the detachable mounting support, and the positions of the guide wheels can be adjusted through adjusting the mounting state of the mounting support according to the practical requirement, so that the clearances between the guide wheels and the tower body during assembly are controlled in a reasonable range, the clearances between the guide wheels and the tower body during assembly meet the assembly requirement, rectification caused by processing errors is reduced, and the qualification rate of a tower crane is increased.
