The utility model is installed on the translation rolling plate clamp, when the translation rolling plate clamp is worked, driving driver remote control is opened, by the direct motor drive reductor moment of torsion is passed to torque limiter, torque limiter connects the transmission shaft that small spiral bevel gear is housed, pass to the king bolt bevel gear for 90 ° by small spiral bevel gear, the king bolt bevel gear is realized the switching of tong arm again by the gear on the gear wheel shaft and the engagement of two tooth bars up and down.Brake ratchet is equipped with in end at gear wheel shaft, and the braking ratchet links to each other with electromagnet.Reductor stops operating after the clamp clamping puts in place, clamps to stop thereupon, and at this moment electromagnet gets electric elongation, and electromagnet drives ratchet and rotates the tooth root portion that snaps into ratchet, plays the purpose of braking.When tong arm clamp or open put in place after, the motor braking of reductor, the tong arm stop motion begins to carry out next job procedure.

Actuating device of the present utility model operates steadily, and noise is little; Electromagnetic braking accurately and reliably; Self-aligning roller bearing can reduce to add the manufacturing deficiency that man-hour, crossbeam two side holes decentraction was brought by actv., makes the gear wheel shaft running light, efficient.Reductor possesses braking function, can adjust according to the width range of suspended object.Torque limiter can reduce to clamp impact, and torque limiting plays the effect of protection suspended object.The utility model compact conformation, from heavy and light, safety factor height, the intensity height, cost is low; Can realize automatic, semi-automatic operation, high efficiency alleviates labor strength.
