Embodiment

[0041] The embodiment of the present invention provides a method for processing the rope groove of the drum, which is especially suitable for processing the rope groove of the drum of the ultra-large offshore crane. The method can be realized by using a numerical control machine tool, see figure 1 , the method includes:

[0042] Step 101: The operator determines the size of the designed rope groove, and the designed size of the rope groove includes the radius of the designed rope groove.

[0043] In this embodiment, the designed rope groove is an ideal rope groove with a surface roughness of 0. The section of the ideal rope groove is a standard arc shape, and the surface roughness is the maximum distance between the non-coincident points of the rope groove section and the standard arc surface of the same radius when the center of the circle coincides. The size of the designed rope groove also includes the depth of the designed rope groove and / or the included angle of the arc ...

Abstract

The invention discloses a method for processing a coiling block rope race and belongs to the field of machinery. The method includes acquiring the size of the designed rope race and the radius of a selected arc cutter, wherein the size of the designed rope race includes the radius and the depth of the designed rope race and an angle formed by arch surfaces between a starting point and an end point of a cross surface of the designed rope race, and the radius of the selected arc cutter is smaller than that of the designed rope race; acquiring starting coordinates of n-time processes when the selected arc cutter processes the rope race which meets surface roughness requirements, wherein n>=2, and n is an integer; rotating a coiling block, moving the selected arc cutter according to a predetermined track, and performing n-time processing to obtain the rope race, wherein the i processing is performed, the selected arc cutter begins to move from the obtained starting coordinate of the i processing, 1<=i<=n, and i is an integer. According to the method for the method for processing the coiling block rope race, conditions of messing and clamping of ropes can be avoided, and processing efficiency is high.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a processing method for a drum rope groove. Background technique [0002] At present, in the field of construction machinery, hoisting machinery (such as cranes, winches) generally realizes the lifting of heavy objects by winding or releasing steel wire ropes on the drum. The higher the hoisting height of the hoisting machinery, the more coils the wire rope is wound on the drum, and the easier it is to cause disordered ropes and rope jams during the lifting of heavy objects, which will affect the service life of the wire rope in the slightest and cause security incident. [0003] In order to avoid the occurrence of messy ropes and rope jams, the drum rope grooves are usually designed and processed according to the lifting height of the hoisting machinery. The existing processing method of the drum rope groove includes: according to the lifting height of the hoisting machine, design the...
