Abstract

The invention relates to engineering machinery, and discloses a rolling wheel assembly of a climbing frame and a tower crane. The rolling wheel assembly of the climbing frame comprises a hinged arm (4), a rolling wheel (3) and a screw rod (6). The rolling wheel (3) is rotatably installed at the first end of the hinged arm (4) and can abut against a standard joint, the hinged arm (4) is rotatably hinged to the climbing frame (2), the screw rod (6) can be in screw joint to the climbing frame (2), the screw rod (6) can abut against the hinged arm (4), and the screw rod (6) can rotate relative to the climbing frame (2) so as to push the hinged arm (4) to rotate around a hinged shaft (9). Through the above technical scheme, the position of the hinged arm is adjusted through the screw rod, the distance between the rolling wheel and a main chord member can be adjusted more accurately, the distance between the rolling wheel and the main chord member is kept within a more accurate range, the adjustable rolling wheel structure can allow low production accuracy, and production cost is reduced.

Description

technical field [0001] The invention relates to engineering machinery, in particular to a roller assembly of a climbing frame, and to a tower crane. Background technique [0002] There are two types of rollers for the existing tower crane climbing frame: fixed rollers and adjustable rollers. Proper roller clearance needs to be maintained between the climbing frame rollers and the standard section. [0003] The roller gap affects the safety during the lifting process of the climbing frame, and the control of the roller gap is extremely important. Among them, the fixed roller type requires extremely high manufacturing precision. Once the gap does not meet the standard, it cannot be adjusted and controlled, and the rectification is time-consuming and laborious; the current adjustable roller type has a complex structure and high production cost. It is rarely used on small and medium-sized tower climbing frames. It is not easy to disassemble and assemble after the roller frame ...
