Claims (1)

[Claims for Utility Model Registration] 1. An insertion hole 2 is formed in the center of the support frame 1, and a lifting peak 3 and a dropping valley 4 are formed on the upper surface of the circumferential portion of the support frame 1 so as to be aligned in the circumferential direction. A locking shaft 5 is slidably and rotatably passed through the insertion hole 2 of the support frame 1, and a locking pawl 6 and a spring receiver 7 are integrally formed in the lower part of the locking shaft 5 in order from the bottom. A riding part 8 and a lifting/rotating operation part 9 are provided in order from the bottom on the upper part of the locking shaft 5, and a compression spring 10 is stretched between the lower surface of the support frame 1 and the spring receiving part 7 of the locking shaft 5. In the locking state A in which the raised portion 8 has fallen into the drop-down trough 4, the locking pawl 6 is held pressed down to the locking position X by the tension of the compression spring 10. On the other hand, in the unlocked state B in which the climbing part 8 has climbed onto the lifting peak part 3 by the pulling up/rotation operation of the pulling up/rotation operation part 9, the locking claw 6 resists the tension of the compression spring 10. In a device for positioning and fixing a fork of a cargo handling machine on a support rail, the fork is held pulled up to the unlocking position Y. A pair of left and right legs 11, 11 of the lifting/rotating operation section 9 are formed as parts in an inverted U shape.
A pair of left and right raised parts 8, 8 are formed on the lower surface of the
Each engagement pin 12,
12 are integrally provided inwardly protruding, the engagement hole 13 is passed through the upper part of the locking shaft 5, and each engagement pin 1 is inserted from both ends of the engagement hole 13 toward the inside of the hole.
1. A positioning and fixing device for a fork of a cargo handling machine on a support rail, characterized in that 2 and 12 are fitted and engaged. 2 A lifting/rotating operation part 9 is provided on the lifting mountain part 3.
recess 1 for positioning the legs 11, 11 of the
7. The positioning and fixing device according to claim 1, further comprising: 7. 3. The positioning and fixing device according to claim 1, wherein the pulling/rotating operation section 9 is swingably provided on the locking shaft 5.
