A reversible channel connection structure and crawler crane

Abstract

The invention relates to a reversible channel connection structure and a crawler crane, wherein the reversible channel connection structure comprises a support and a channel; the middle position at one side of the channel is suspended with the lateral wall of a mechanical structural member through at least one support; a support through hole is formed in the support; a gap structure is formed in the edge position of the support; a first channel through hole is formed in the channel; the support through hole is matched with the first channel through hole and connected through a first pin shaft; a second channel through hole is also formed in the channel; the channel is in a transportation state of reversing upwards; the second channel through hole is matched with the gap structure, and connected through a second pin shaft. The support is arranged at the middle position at one side of the channel, a gap between the two adjacent channels can be reduced as possible, the phenomena such as dropping of a foreign matter are avoided, the connection points correspond to a same component, the distance is small, the problem that the size is difficultly ensured in production and processing processes is solved, and the overall beautiful degree is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a reversible channel connection structure and a crawler crane. Background technique [0002] The platform / channel is the aisle suspended on the side of the lifting machinery structure to meet the requirements of personnel passing, maintenance standing, passing, etc. On crawler crane products, the platforms / passages are generally removed during transshipment and transported separately. Each channel weighs more than 30 kilograms, and each disassembly and assembly requires the cooperation of at least 2 people. Moreover, it needs to be placed separately during transportation after being dismantled, and it needs to be re-confirmed during installation, and it needs to be transported and installed, which requires a lot of manpower and time. [0003] The platform / channel is a very frequently used part on the crane. Almost all medium and large-tonnage lifting machinery products are ...
