Embodiment Construction

[0021] Examples of self-climbing cranes, such as Figure 1-3 As shown, the self-climbing crane includes a self-climbing device and a lifting device 102 arranged on the self-climbing device. The self-climbing device includes a guide sleeve 12, a guide rod 13, a supporting platform 11 and an arm assembly.

[0022] The guide rod 13 is inserted in the guide sleeve 12 and guides and slides with the guide sleeve 12 . In this embodiment, both ends of the guide rod 13 extend outside the guide sleeve 12 . A telescopic driving device is arranged between the guide sleeve 12 and the guide rod 13. One end of the telescopic driving device is connected to the guide rod 13, and the other end is connected to the guide sleeve 12. The telescopic driving device can drive the guide rod 13 and the guide sleeve 12 along the axial direction. For relative movement, in this embodiment, the hydraulic cylinder 14 is specifically used as the telescopic drive device.

[0023] The arm assembly is provided ...

Abstract

The invention relates to the field of lifting devices, and in particular to a self-climbing crane. The self-climbing crane comprises a self-climbing device and a lifting device fixedly assembled on the self-climbing device. The self-climbing device comprises two or more holding arm assemblies. The crane further comprises a guide rod and a guide sleeve which are sleeved together in an inserted manner and are in guide coordination. The guide rod and the guide sleeve are each provided with at least one holding arm assembly, and a telescopic driving device is arranged between the guide sleeve and the guide rod. When the self-climbing crane is used, the holding arm assemblies on the guide rod and the guide sleeve can work alternately to stabilize devices to corresponding vertical rods; the guide rod and the guide sleeve are lifted alternately through the telescopic driving device to achieve the climbing purpose so that automatic climbing can be achieved; and in addition, mutual guiding between the single guide rod and the guide sleeve is more smooth, and the problems of clamping and deforming can be more not likely to happen. Thus, the problems that an existing climbing type wind power equipment overhauling crane is likely to be abraded and poor in reliability are solved.

Description

technical field [0001] The invention relates to the field of lifting equipment, in particular to a self-climbing crane. Background technique [0002] In the process of power maintenance, operators are often required to climb up poles such as utility poles. Especially in recent years, with the promotion and development of clean energy, wind power technology has made great progress. In the process of wind power construction, wind power hoisting is an extremely critical process. By the end of 2014, China's wind power grid-connected installed capacity has exceeded 90 million kilowatts, and the annual power generation is expected to be 150 billion kilowatt-hours. By the end of 2015, the scale of wind power will reach 100 million kilowatts. However, the failure rate of wind power equipment has always been an important issue plaguing the wind power industry. According to relevant statistics, China's wind power operation and maintenance market will exceed 100 billion yuan in 2020....
