[0002] The oil loading arm used at the 300,000-ton ultra-large oil tanker terminal plays an important role in connecting the ship's side and the crude oil pipeline of the terminal. The oil loading arm includes an inner arm, an outer arm, a three-dimensional joint, a rotating platform, a column, etc. When a typhoon is about to pass by, it is necessary to anchor the oil loading arm. During the anchoring process, technicians need to climb up the fixed vertical ladder to the rotating platform and manually fix the anchor plate with bolts. To release the anchoring, the bolts are removed and the anchor plate is lowered, thus completing the operations of anchoring and releasing the anchoring of the oil loading arm.

[0003] However, when the staff anchors and releases the anchoring of the oil loading arm, technicians need to perform high-altitude operations, which brings safety risks.

The third gear 302 is rotatably connected to the inside of the support box 1 below and to the right of the first gear 301. The fourth gear 304 is rotatably connected to the inside of the support box 1 on the right side of the third gear 303.

[0030] The electromagnetic anchoring system includes a movable anchoring plate 401, a rack 402, a roller 403, a stop plate 1 404, a stop plate 2 405, an anchoring box 406, and an electromagnetic expander 407. The movable anchoring plate 401 is installed on the right side inside the support box 1. The rack 402 is fixedly installed at the upper and lower ends on the left side of the movable anchoring plate 401. The roller 403 is fixedly installed on the sides of the movable anchoring plate 401 and the rack 402. A chute is provided on the inner wall of the support box 1, and the roller 403 is connected to roll inside the chute.
