Problems solved by technology
Different from the installation method of the conventional slewing mechanism, the inverted slewing mechanism needs to open bolt holes from the lower opening of the steel structure from bottom to top, that is, according to a circle of mounting holes on the lower positioning plate itself, the bolt holes of the lower opening of the steel structure are inverted and drilled. , which leads to low precision of drill matching and low processing efficiency, which affects the overall work efficiency

The invention provides a rotation mechanism rowing mounting method. The rowing mounting method comprises the following steps that a process positioning plate is machined, the process positioning plate and a lower positioning plate is consistent in structure, the lower positioning plate is provided with first mounting holes, and the process positioning plate is provided with second mounting holes; the lower positioning plate is fixed to the bottom face of a main steel structure lower opening, the process positioning plate is fixed to the top face of the main steel structure lower opening; a rotation mechanism is assembled in place so as to penetrates through a through hole of the main steel structure lower opening, and a gear ring of the rotation mechanism is adjusted to be engaged with a gear ring of a pivotal bearing of a main steel structure; and at least two positioning holes are machined in the main steel structure lower opening according to the first mounting holes of the lower positioning plate. The rotation mechanism rowing mounting method provided by the invention can improve the matching drilling precision and machining efficiency, and thus the overall working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of cranes, in particular to a method for arranging and assembling a slewing mechanism. Background technique [0002] With the diversification of crane functions, the steel structure is becoming more and more complex, resulting in some structures unable to meet the arrangement of conventional mechanisms due to space reasons, so the inverted slewing mechanism has gradually been widely promoted and applied. [0003] The existing inverted slewing mechanism usually adopts the lower positioning plate to connect with the lower opening of the steel structure with bolts. Different from the installation method of the conventional slewing mechanism, the inverted slewing mechanism needs to open bolt holes from the lower opening of the steel structure from bottom to top, that is, according to a circle of mounting holes on the lower positioning plate itself, the bolt holes of the lower opening of the steel structure are i...
