[0014] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0015] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] like Figures 1 to 3 As shown, this utility model provides a socket structure for the lifeline of an oil drilling and repair equipment platform, including: a plug rod 4, a socket 2, and a fixing plate 3 disposed on the platform 1; the top surface of the platform 1 is provided with an opening, the fixing plate 3 is fixedly connected to the inner wall of the opening, the socket 2 is fixedly disposed on the fixing plate 3, and the socket 2 and the fixing plate 3 are coaxially provided with a through hole through which the plug rod 4 can pass; the lower end of the plug rod 4 is detachably connected to the socket 2; the upper end of the plug rod 4 is provided with a plurality of vertically arranged ear plates 6, and the top surface of the socket 2 is provided with a slot 21 corresponding to each ear plate 6; when the ear plate 6 of the plug rod 4 is inserted into the slot 21, the lower part of the plug rod 4 extends into the interior of the platform 1.

[0017] In this technical solution, refer to Figure 1 This is a bottom view of the platform 1. The fixing plate 3 is fixed to the inner wall of the opening of the platform 1 so that the insertion rod 4 can extend upward from the opening to meet the lifeline installation requirements. In use, the bottom of the insertion rod 4 is connected to the socket 2, and then the steel wire rope of the lifeline system is connected to the ear plate 6 at the upper end of the insertion rod 4. After the lifeline is installed, the connection between the insertion rod 4 and the socket 2 is released, and the insertion rod 4 is lowered until the ear plate 6 is inserted into the corresponding slot 21. At this time, the insertion rod 4 is hung on the socket 2 through the ear plate 6, and the lower part of the insertion rod 4 is hidden inside the platform 1. The socket structure avoids the problems of existing technologies where, after each installation and removal of the lifeline, the plug needs to be transported to the ground for separate storage, and then hoisted back onto the platform for installation the next time. The socket structure can be hidden when not in use, and the storage process is simple and quick, which can save time and improve work efficiency. The plug 4 is stored inside the platform 1, which can save well site space and eliminate the need for separate storage of toolboxes; it also saves the use of crane equipment.

[0018] In another technical solution, at the upper end of the insertion rod 4, each of the ear plates 6 is at the same height, and the included angle between two adjacent ear plates 6 is 90°; the installation requirements of the lifeline are met by the ear plates 6 at different positions.

[0019] In another technical solution, the detachable connection between the socket 2 and the plug rod 4 is achieved through the cooperation of a pin and a socket. The lower end of the plug rod 4 and the socket 2 are respectively provided with multiple sockets 7 for the pin to be inserted.

[0020] Specifically, the socket 2 is provided with two socket holes 7, which are symmetrically arranged about the center of the socket 2; an even number of socket holes 7 are arranged at the same height at the lower end of the plug rod 4, and every two socket holes 7 form a group, with the two socket holes 7 in the same group being symmetrically arranged about the center of the plug rod 4. The socket holes in each group are evenly distributed on the plug rod 4. The plugs in different groups on the plug rod 4 are connected to the corresponding socket holes on the socket 2 using the pins, and the orientation of the ear plate 6 is adjusted. In actual use, the pins can be further fixed to the socket using a fixing structure to prevent the pins from being lost and to achieve simultaneous storage of the pins. The fixing structure is configured in two sets corresponding to the two sockets 7 on the socket 2. The fixing structure includes a limiting plate, an L-shaped connecting plate, and a spring. The horizontal part of the connecting plate is fixedly connected to the socket 2, and the vertical part is parallel to the socket 2 and has a through hole facing the socket 7. The limiting plate is fixedly sleeved on the pin, with one end of the pin extending out of the through hole of the vertical part and the other end inserted into the socket 7. The spring is sleeved on the pin, with one end fixedly connected to the vertical part of the connecting plate and the other end fixedly connected to the limiting plate. Simultaneously pulling one end of the pin extending out of the vertical part on both fixing structures causes the limiting plate to compress the spring, causing the other end of the pin to disengage from the socket 2. After aligning the plug rod 4 with the socket 2, the pulling of the pin is released, and under the action of the spring, the pin is reinserted into the corresponding socket, realizing the connection between the plug rod 4 and the socket 2.

[0021] Furthermore, the detachable connection between the socket 2 and the plug rod 4 can also be achieved through a threaded connection. The inner wall of the socket 2 is provided with an internal thread section, and the lower outer wall of the plug rod 4 is provided with an external thread section that mates with the internal thread section.

[0022] In another technical solution, the fixing plate 3 is further provided with two reinforcing plates 5, which are respectively disposed on both sides of the socket 2. One end of each reinforcing plate 5 is fixedly connected to the auxiliary platform 1, and the other end is fixedly connected to the socket 2. The reinforcing plates 5 further fix the socket 2, increasing the stability of the socket structure.

[0023] In another technical solution, the top of the socket 2 does not extend out of the platform 1; when the ear plate 6 of the plug 4 is located in the slot 21 of the socket 2, the top of the plug 4 does not extend out of the platform 1; that is, when the plug 4 is hung on the socket 2, the plug 4 is also located below the top surface of the platform 1.

[0024] Furthermore, a cover plate is movably installed on the platform 1. In the folded state, the cover plate covers the platform 1, completely concealing the socket structure. Operators can walk freely on the cover plate without affecting the work of other processes.

[0025] In another technical solution, an annular buffer pad is fixedly provided on the inner wall of the socket 2 or on the bottom of the fixing plate 3 corresponding to the through hole. The buffer pad prevents the plug rod 4 from rigidly colliding with the socket 2 or slot 21 when it falls freely, thus avoiding damage and noise and increasing the service life of the socket structure.

[0026] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
