Manufacturing method of double-tube ring beam

Abstract

The invention discloses a method for manufacturing a double-tube ring beam, which belongs to the field of engineering equipment. The present invention draws a line on the platform first, then, according to the assembly line of the inner cylinder, vertically places the inner cylinder on the processing platform; then assembles the vertical plate and the ring rib, and divides the vertical plate into four groups; then , according to the assembly line of the outer cylinder, assemble the outer cylinder to each set of vertical plates; then, according to the assembly line of the pin seat, insert each pin seat between two adjacent sets of vertical plates; finally, weld the inner cylinder, vertical Plate, ring rib, outer cylinder and pin seat, thereby completing the positioning and installation of the pin seat, and the positioning of the pin seat can also ensure the positioning and installation of the pin seat in the follow-up process. The dimensions of the double-tube ring beam structural parts manufactured by the manufacturing method all meet the design requirements, and the double-tube ring beam structural parts whose quality meets the requirements can be manufactured.

Description

technical field [0001] The invention belongs to the field of engineering equipment, in particular to a method for manufacturing a double-tube ring beam. Background technique [0002] The hydraulic plug-type platform lifting system consists of three parts: the mechanical body, the hydraulic system and the electrical system. The mechanical part mainly includes pile fixing frame, ring beam, lifting cylinder and bolt cylinder, among which the ring beam is an important force-bearing and force-transmitting component of the lifting system. [0003] The double-tube ring beam is a kind of ring beam whose inner cylinder and outer cylinder are both cylindrical. By fixing the double-tube ring beam on the pile frame, the lifting cylinder and the bolt cylinder are fixed on the double-tube On the ring beam, the lifting and lowering functions of the entire lifting system are realized by using the alternate expansion and contraction of the bolts and the expansion and contraction of the lift...

AI Technical Summary

Problems solved by technology

[0004] However, the current double-tube ring beam structure is difficult to manufacture. Multiple pin seats and ring ribs need to be welded on the inner and outer cylinders, and the welding volume is large. Therefore, once the welding deformation of the double-tube ring beam is formed, it cannot be corrected. It is easy to lead to the scrapping of double-tube ring beams
