Abstract

The invention discloses a method for processing a main cable saddle of a suspension bridge. A side span (1) and a midspan (2) of the main cable saddle are respectively processed, then a bolt (3) is used to connect the side span and the midspan, and a joint surface of the side span (1) and the midspan (2) is provided with a positioning pin hole (6). The method guarantees the consistency of the size of a rope groove after the side span (1) and the midspan (2) are butted, has no alternate edges, high butting accuracy and small error, unifies processing reference, has low requirement on processing equipment, is more convenient for clamping and calibration of workpieces, is easy to guarantee processing accuracy, and improves processing efficiency.

Description

technical field [0001] The invention relates to a processing method of mechanical parts, in particular to a processing method of a main cable saddle of a suspension bridge. Background technique [0002] The main cable saddle of the suspension bridge is arranged on the main tower of the bridge, and the main cable is embedded in the rope groove of the main cable saddle. The weight of the entire bridge body and vehicles is transmitted to the main bridge tower through the main cable saddle. The main cable saddle is a key part of the whole bridge. , its manufacturing quality directly affects the quality and safety of the bridge. like figure 1 As shown, the main cable saddle structure is generally divided into side span 1 and middle span 2, and the two parts are connected into a whole by high-strength bolts 3 in the middle. The existing processing method of the main cable saddle is to lock the two parts of the side span 1 and the middle span 2 with the bolt 3 before cutting. Th...
