| description | The invention discloses an electric triggering device for a torsion spring type safety tongs lifting device. The electric triggering device comprises a transmission shaft and an action torsion spring. The transmission shaft is provided with a left lifting arm, a spring side transmission shaft supporting frame, a right lifting arm and a non-spring side transmission shaft supporting frame. The left lifting arm and the right lifting arm are respectively connected with the safety tongs; the transmission shaft penetrates through the action torsion spring; one end of the action torsion spring is fixed on the spring side transmission shaft support frame, and the other end is limited by a spring limiting device; a driving device is mounted on the spring side transmission shaft support frame; an upper limiting piece and a lower limiting piece are respectively arranged on the spring side transmission shaft support frame; a friction coupling device is arranged in the middle of the transmission shaft; an electric telesco |
