Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 3, a bell mouth maintenance folding platform for an ocean well servicing rig comprises folding platforms 2 arranged on a deck 3 of the well servicing rig on two sides of a bell mouth 1, wherein each folding platform 2 is composed of a first steel plate 21 and a second steel plate 22 which can be folded; one end of the first steel plate 21 is rotatably connected with the workover rig deck 3, and the second steel plate 22 at the other end is abutted with the bell mouth 1; the bottom end of the second steel plate 22 is fixedly provided with angle steel 24, the bottom end of the first steel plate 21 is fixedly provided with H-shaped steel 25, the angle steel 24 close to one side of the first steel plate 21 is fixedly provided with a supporting steel plate 26 abutted against a web of the H-shaped steel 25, and the H-shaped steel 25 close to one side of the deck 3 is fixedly provided with a supporting steel plate 26 abutted against a web of a workover rig H-shaped steel 27 at the bottom side of the deck 3.
Wherein, first steel sheet 21 top surface one end is provided with connecting pin ear 23, and the other end is provided with fixing pin ear 4, and connecting pin ear 23 of first steel sheet 21 rotates with fixing pin ear 4 that sets up on the 3 top surfaces of deck to be connected, second steel sheet 22 top surface one end is provided with and rotates connecting pin ear 23 of being connected with fixing pin ear 4 of first steel sheet 21, supporting steel sheet 26 is right trapezoid, and supporting steel sheet 26's hypotenuse is towards the bottom of folding platform 2.
