and a reinforced longitudinal small toggle plate is arranged at the included angle between the front side surface of the reinforced transverse toggle plate and the bottom plate of the bracket.
The area of the reinforced large longitudinal toggle plate is larger than that of the reinforced small longitudinal toggle plate.
Two reinforcing large longitudinal toggle plates are arranged.
One reinforcing longitudinal small toggle plate is arranged.
The reinforced longitudinal big toggle plate and the reinforced longitudinal small toggle plate are triangular plates.
The top surface of the reinforced transverse toggle plate is an arc surface formed by rotating around the first horizontal rotating shaft.
The top surface of the flange supporting arc bottom plate is an arc surface formed by rotating around the second horizontal rotating shaft.
The arc line formed by the arrangement of the bolt holes is positioned on the arc surface formed around the second horizontal rotating shaft.
The first horizontal rotating shaft, the second horizontal rotating shaft and the third horizontal rotating shaft are all overlapped.
Compared with the prior art, the invention has the advantages of simple structure, convenient construction and convenient maintenance of the pipe bracket by a crew; according to the invention, the polyethylene pad is arranged, so that the pipeline and the bracket are effectively protected, and the service life of the pipe bracket is prolonged; the triangular toggle plate adopted by the invention has stable structure and high structural strength; the invention adopts the bolt for fixed connection, which is convenient for maintenance and maintenance of the crew to replace the pipe bracket; the pipeline flange is used for arranging the pipe bracket, so that the material use cost is reduced, and compared with the traditional pipe, the pipeline flange avoids damage to the pipeline; the invention improves the integral performance of the pipe bracket and the construction quality of the FPSO ship.
