[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0035] According to an embodiment of the present invention, Figure 1 and Figure 2 As shown, a universal threshold crossing device is provided, including a base 1, a platform panel 2 and a first ramp 3. A receiving space 101 is provided at the bottom of the base 1, and the receiving space 101 is suitable for being placed above an obstacle. The platform panel 2 is rotatably mounted on the top of the base 1, and one end of the first ramp 3 is movably connected to the edge of the platform panel 2, and the other end of the first ramp 3 has a supporting state abutting against the side of the obstacle to be crossed, and a storage state separated from the side to be crossed.

[0036] Specifically, the environment in which the universal threshold device is applied is not specifically limited in this embodiment. To conform to the actual situation, the universal threshold device in this embodiment is used during the construction and installation of the offshore platform and in the subsequent operation and maintenance work.

[0037] In this embodiment, the shape of the base 1 is not specifically limited. In this embodiment, a receiving space 101 is provided at the bottom of the base 1. The receiving space 101 is used to be placed above an obstacle, and the height of the receiving space 101 should not be less than the height of the obstacle.

[0038] In this embodiment, the top of the base 1 is a horizontal plane, and the platform panel 2 is a flat plate structure, and its bottom is rotatably connected to the top of the base 1. In this embodiment, the shape of the platform panel 2 is not specifically limited. In order to conform to the actual situation, in this embodiment, the platform panel 2 is a circular flat plate, and a protruding transition portion 202 is provided on the circular flat plate. One side of the first ramp 3 is movably connected to the transition portion 202. The platform panel 2 can rotate 360° relative to the base 1, so that the first ramp 3 can be rotated from one position to any angle and then located at another position.

[0039] In this embodiment, the first ramp 3 is hingedly connected to the edge of the platform panel 2. When the first ramp 3 is not in use, the first ramp 3 can be folded and stored at the top of the platform panel 2. When equipment or materials need to be transported, the first ramp 3 is unfolded and supported on the side to be crossed in front of the obstacle, and then the equipment or materials are transported to the platform panel 2 through the first ramp 3. After the first ramp 3 is lifted and the platform panel 2 is rotated a certain angle to a suitable position, the first ramp 3 is supported again at the position where the equipment or materials need to be unloaded. After the equipment or materials are moved and unloaded from the first ramp 3, the obstacle can be crossed.

[0040] The overall structure of the present invention occupies a small space and is suitable for setting up a compact space environment in an offshore platform. When the width of the corridor of the offshore platform is limited, there are obstacles such as thresholds, pipelines, and lines, and the obstacles are of different forms, when it is necessary to transport equipment or materials across obstacles set at corners, the equipment or materials are moved from the first ramp 3 to the platform panel 2, and the platform panel 2 is rotated to the angle at which it needs to be lowered, and then the equipment or materials are unloaded through the first ramp 3, thereby realizing the operation of the equipment or materials at the turning point with obstacles. The present invention has the advantages of simple structure, convenient operation, easy storage, and good practicality.

[0041] In one embodiment, Figure 3 and Figure 4 As shown, the universal threshold device also includes a second ramp 4, one end of which is movably connected to the top of the base 1, and the other end of the second ramp 4 has a supporting state abutting against the obstacle crossing side, and a storage state separated from the crossing side.

[0042] Specifically, in this embodiment, the second ramp 4 is hinged to the side position of the top of the base 1, and the second ramp 4 can be folded and stored to the top of the platform panel 2. After the first ramp 3 and the second ramp 4 are stored to the top of the platform panel 2, the space occupied by the universal threshold device can be reduced.

[0043] In this embodiment, two ramps are set up. When the universal threshold device is placed, the platform panel 2 can be rotated to a suitable position, and the first ramp 3 and the second ramp 4 can be unfolded at the same time. The equipment or materials to be operated can be transported in sequence by the first ramp 3, the platform panel 2 and the second ramp 4. There is no need to make a secondary adjustment to the universal threshold device, which is more convenient to use.

[0044] The present invention sets a second ramp 4. When equipment or materials are operated at a turning place with obstacles, the second ramp 4 can be set in the direction of moving out the equipment or materials, and the platform panel 2 is rotated to set the first ramp 3 in front of the obstacle. The equipment or materials can be sequentially passed through the first ramp 3, the platform panel 2 and the second ramp 4 to realize the operation of the equipment or materials at the turning place with obstacles, thereby reducing the adjustment of the device during the operation of the equipment or materials, simplifying the operation process of the equipment or materials, and improving the operation efficiency of the equipment or materials.
