[0014] The utility model is described in detail in connection with specific implementation manners below:
[0015] As Figures 1 to 3 The expansion shaft pay-off machine anti-drop limiting mechanism shown in the utility model discloses a expansion shaft pay-off machine anti-drop limiting mechanism, including rotating table 1, middle shaft 2, sliding sleeve 3, flange 4, limiting body 5, telescopic guide cylinder 6 and electric push rod 7, middle shaft 2 is fixedly installed on rotating table 1, the sliding sleeve 3 is fixedly sleeved and installed at the top of middle shaft 2, a plurality of limiting body 5 is arranged in rectangular distribution with middle shaft 2 as the center, the inner end of limiting body 5 is hingedly installed on sliding sleeve 3, the cylinder body of telescopic guide cylinder 6 is hinged with flange 4 and forms first hinged point, the piston rod of telescopic guide cylinder 6 is hinged with limiting body 5, electric push rod 7 is fixedly installed in middle shaft 2, the execution rod of electric push rod 7 is hinged with the bottom surface center position of flange 4 and forms second hinged point, second hinged point is located on the outside of first hinged point, and there is 10-15cm spacing between second hinged point and first hinged point.
[0016] The limiting body 5 top is provided with the accommodating groove 51 that cooperates with telescopic guide cylinder 6, when limiting body 5 is in the contraction state, the cylinder body of telescopic guide cylinder 6 is located in the accommodating groove 51 of limiting body 5, further improves the contraction degree of limiting body 5.
