Title: Pin-connecting device in construction machine
Inventor: NAGURA AKIHIRO
IPC: B66C23/687
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent a pin from breaking by eliminating stress concentration caused by local contact between the pin and a pin hole, and remove a vertically adjusting mechanism for positioning the pin and the pin hole when the pin is passed through the pin hole. SOLUTION: This device pierces a pin hole 13 in the side of an inner boom 6a when an outer boom 5 and the inner boom 6a in a construction machine are connected to each other through a pin. The pin hole 13 is formed as an oblong hole where a large-diameter circular hole 14 and a small-diameter circular hole 15 are superposed on each other, and the diameter of the small-diameter circular hole 15 is set equal to the outer diameter of a pin 7. When the pin 7 is protruded toward the large-diameter circular hole 14 from the side of the outer boom 5, the pin 7 can be passed through the pin hole 13 easily because the diameter of the large-diameter circular hole 4 is larger enough than the outer diameter of the pin 7.  Furthermore, when the pin hole 13 is moved slightly by shrinking the inner boom 6a, and the center of the small- diameter circular hole 15 is made to coincide with that of the diameter of the pin 7, the outside of the pin 7 uniformly contacts with the small-diameter circular hole 15 over substantially half circumference of the pin 7, and the stress concentration can be prevented from occurring.
