Automatic bolt dismounting and mounting device for flange plate connection

The invention discloses an automatic bolt dismounting device for flange connection, which comprises clamping sleeves symmetrically arranged on the outer surface of a flange and used for mounting the dismounting device, a driving motor used for providing power for bolt dismounting is arranged on the outer surface of one of the clamping sleeves, and a rotating disc used for matched transmission is arranged in the clamping sleeve. The pipe body is sleeved with the oppositely-opened clamping sleeve, the oppositely-opened clamping sleeve is moved to enable the bolt sleeve heads to be matched with the bolts, the motor is controlled to rotate forwards and backwards through the switch, power is transmitted to the bolt sleeve heads, the clamping sleeve is arranged in the pipe body, the clamping sleeve is arranged in the pipe body in a sleeving mode, and the clamping sleeve is arranged in the pipe body in a sleeving mode. The quick bolt mounting and dismounting device has the advantages of being compact in structure, e
