Problems solved by technology

[0003] However, in the above process, the loading and unloading, positioning, and pressing of the main chord are all done manually, so the workload is huge, and the labor intensity of the staff is extremely high due to the heavy weight of the main chord; In the process of positioning, deviations are prone to occur, and frequent positioning adjustments further increase the labor intensity; the milled main chord will produce deviations and deformations in the subsequent tailor welding, resulting in the flatness of the two ends of the standard section after welding. degree and parallelism are far greater than the machining accuracy of a single main chord

Abstract

The invention discloses a device for processing a standard joint of a tower crane. The device is used for milling two end faces of each main chord member of the welded standard joint. The processing device comprises two special milling machines, a processing platform and a positioning and clamping device, wherein the processing platform comprises a left side part and a right side part which are parallel to each other and are arranged opposite to each other; a mounting part is encircled between the left side part and the right side part; a standard joint to be processed is arranged in the mounting part; the special milling machines are arranged on the processing platform and are used for milling the two end faces of each main chord member; the special milling machines are arranged at two ends of the standard joint, respectively; the positioning and clamping device is arranged on the left side part and the right side part of the processing platform and faces the mounting part; the positioning and clamping device is used for positioning and clamping the standard joint arranged in the mounting part. The invention also provides a method for milling the two end faces of each main chord member of the standard joint by adopting the processing device.

Description

technical field [0001] The invention relates to the field of tower cranes, in particular to a processing device and a processing method for milling a standard section of a tower crane. Background technique [0002] The standard section is the basic unit of the tower crane body and the most basic and important component of the tower crane. The machining accuracy of the standard section directly affects the quality of the tower crane. The existing standard section is to take the four independent main chords that make up the standard section as a group, manually install them on the processing platform, position them and press them tightly, mill the two end faces of the main chords with a milling machine, and then place the The main chord is tailor-welded into a standard section on a special tooling. [0003] However, in the above process, the loading and unloading, positioning, and pressing of the main chord are all done manually, so the workload is huge, and the labor intensi...
