Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building hoisting machinery, and in particular to an adjustable outer sleeve frame guide wheel system. BACKGROUND

[0002] The guide wheel system is a component of the outer sleeve frame of a tower crane. The outer sleeve frame is raised or lowered along the tower body under the action of the hydraulic lifting system, and the guide wheel system rolls with the tower body branch during the movement of the outer sleeve frame, thereby supporting and reducing friction to ensure smooth completion of the tower crane lifting operation.

[0003] The conventional outer sleeve frame adopts a pin shaft matched with a guide wheel, and the guide wheel is fixed and cannot be adjusted. During the lifting operation of the tower crane, the guide wheel on the outer sleeve frame rolls along the outer surface of the standard section main limb. The conventional outer sleeve frame adopts a fixed mode of pin shaft matched with guide wheel, and the distance of the guide wheel to the standard section main limb cannot be adjusted. However, in actual production and installation, due to the size deviation in production and installation or the deformation of the outer sleeve frame caused by transportation and handling, there may be a large gap between the guide wheel of the outer sleeve frame and the outer surface of the standard section main limb or the guide wheel may not be easily installed. When the gap between the guide wheel and the outer surface of the standard section main limb is too small, it is difficult to install the tower crane and the efficiency is low. When the gap is too large, the outer sleeve frame may be deviated and cannot be normally lifted, and even the tower crane may be overturned.

[0004] Therefore, the design of an adjustable outer sleeve frame guide wheel system is beneficial to improve the installation efficiency of the outer sleeve frame and reduce the safety risk that the outer sleeve frame cannot be normally lifted due to the large gap during the lifting process.

[0018] (2) The installation difficulty is reduced. The gap between the guide wheel of the outer sleeve frame and the outer surface of the standard section main limb is adjustable, which can prevent the problem of installation difficulty caused by too small gap, or appropriately increase the gap to reduce the installation difficulty.

[0019] (3) The jacking safety performance is improved. By fine-tuning the guide wheel, the gap between the guide wheel and the standard section main limb surface is uniform, which ensures that the outer sleeve frame is uniformly stressed during jacking, avoids single limb unbalanced load or local stress problems, and improves the jacking safety performance.
