Description

Technical Field

A plurality of second bolts 221 pass through the corresponding second fixing holes 13, and the inner wall of the plurality of second nuts 222 is threaded to the outer wall of the corresponding second bolts 221. With the above arrangement, relevant personnel pass the plurality of second bolts 221 through the second fixing holes 13 on the corresponding fixing plates 220, and relevant personnel use tools to rotate the plurality of second nuts 222 on the corresponding second bolts 221, thereby fixing the corresponding fixing plates 220 on the two semi-arc housings 20 to each other, and further fixing the two semi-arc housings 20 to the two marine oil pipes 1.

[0035] In this embodiment, specifically, an arc-shaped rubber pad 12 is provided on the inner wall of the semi-arc shell 20. The side of the arc-shaped rubber pad 12 away from the semi-arc shell 20 is in contact with the outer wall of the marine oil pipe 1. The arc-shaped rubber pad 12 is provided to enhance the friction between the semi-arc shell 20 and the marine oil pipe 1.

[0036] When this utility model is in operation: relevant personnel pass several first bolts 31 through the corresponding first fixing holes 4 on the two flanges 30, and then relevant personnel use tools to rotate several first nuts 32 on the corresponding first bolts 31, so that the two flanges 30 are brought closer to each other and fixed, and the two marine oil pipes 1 are further fixed.

[0037] Subsequently, the relevant personnel attached the two semi-circular shells 20 to the two marine oil pipes 1. Then, the relevant personnel passed several second bolts 221 through the second fixing holes 13 on the corresponding fixing plates 220. The relevant personnel used tools to rotate several second nuts 222 on the corresponding second bolts 221, thereby fixing the corresponding fixing plates 220 on the two semi-circular shells 20 to each other, and further fixing the two semi-circular shells 20 to the two marine oil pipes 1.

[0038] When it is necessary to fix the positions of several first bolts 31 and several first nuts 32, the relevant personnel hold the handle 210 to drive the circular rod 212 to rotate. The circular rod 212 drives the external threaded block 211 to rotate out of the internal threaded groove 8. After the external threaded block 211 drives the polygonal groove 14 to fit against the outer wall of the corresponding first bolt 31 and first nut 32, the elastic potential energy of the spring 214 drives the ring plate 213 to move. The ring plate 213 drives the circular rod 212 to move. The circular rod 212 simultaneously drives the external threaded block 211 and two triangular locking blocks 11 to move. The two triangular locking blocks 11 move into the locking groove 10 on the ring 9, thereby fixing the positions of the circular rod 212 and the external threaded block 211.

[0039] When it is necessary to release the positions of the first bolt 31 and the first nut 32, simply reverse the above steps.
