[0045] The present utility model will be further described below in conjunction with the accompanying drawings.

[0046] The cantilever beam system is a key device for connecting the drilling rig structure and the platform of a jack-up drilling platform. During drilling, the cantilever beam system is driven by a sliding device to move on the main deck of the drilling platform to complete multi-well drilling operations. When the cantilever beam system slides, in order to ensure smooth sliding, lubrication is carried out on the track surface of the cantilever beam system to avoid dry friction. However, currently, the commonly used method is manual application of grease, which has low application efficiency, is time-consuming and laborious, and often results in difficult sliding of the cantilever beam due to untimely lubrication, leading to work stoppage. The existing patent CN214332268U discloses an intelligent lubrication system for a drilling rig on an offshore drilling platform. The grease injection system includes a grease storage tank, a grease plunger pump, a lubrication motor, a plunger pump oil pipe, a buffer distributor, an oil pipeline, and a grease point. The grease plunger pump is driven by the lubrication motor. Therefore, this patent requires electricity or hydraulic pressure as a power source, with high costs and a complex structure.

[0047] Embodiment 1

[0048] As Figure 1 、 Figure 4 shown, in order to solve the above technical problems, an embodiment of the present application provides a cantilever beam track lubrication structure, including a support seat 10, an oil tank 20, a lubricating wheel assembly 30, and an elastic member 40; the oil tank 20 is located above the support seat 10, and a lubrication groove for containing lubricant is provided at the top of the oil tank 20; the lubricating wheel assembly 30 is rotatably arranged in the lubrication groove, a lubricating surface part of the lubricating wheel assembly 30 is immersed in the lubricant in the lubrication groove, and the lubricating wheel assembly 30 extends out of the lubrication groove; the elastic member 40 is arranged between the support seat 10 and the oil tank 20; wherein, in the lubrication state, the moving track to be lubricated passes through the lubricating wheel assembly 30 and abuts against the lubricating surface of the lubricating wheel assembly 30, causing the elastic member 40 to undergo compressive deformation, and the lubricating wheel assembly 30 rotates and applies the lubricant to the track to be lubricated.

[0049] As can be seen from the above, by setting the rotatable lubricating wheel assembly 30, when the moving track to be lubricated abuts against the lubricating wheel assembly 30, the lubricating wheel assembly 30 is driven to rotate, and the lubricating wheel assembly 30 evenly applies the lubricant in the fuel tank 20 onto the grease, realizing the automatic lubrication of the cantilever beam track, greatly improving the lubrication effect and lubrication efficiency, avoiding the situation that the cantilever beam slips with difficulty due to untimely lubrication, resulting in shutdown, and the automatic lubrication process does not require electricity or hydraulic pressure as the power source, with low cost. In addition, by setting the elastic member 40 to provide a pre-pressure for the lubricating wheel assembly 30, it is ensured that the lubricating wheel assembly 30 can abut tightly against the track to be lubricated, preparing for lubrication.

[0050] It should be noted that the lubricant can be grease or lubricating oil.

[0051] It should also be noted that a plurality of sliding tables arranged at intervals can be provided on the main deck; the cantilever beam system includes a cantilever beam body and a drill floor and a derrick arranged on the cantilever beam body. The bottom of the cantilever beam body is provided with a track and is movably arranged on the sliding table, and the sliding device on the main deck drives the cantilever beam system to move, enabling the cantilever beam system to extend out of the main deck; when the cantilever beam body moves, the bottom of the track serves as a friction surface and needs to be lubricated; there is a distance of 300 - 400 mm between the bottom of the track and the main deck. Therefore, the cantilever beam track lubrication structure can be arranged here. In addition, the specific structure and working principle of the cantilever beam system are all prior arts and will not be elaborated in this application.

[0052] It should also be noted that the number of the elastic members 40 can be multiple, and the multiple elastic members 40 are arranged at intervals; for example, as Figure 1 、 Figure 4 shown, the number of the elastic members 40 is four, and the four elastic members 40 are respectively located at the corners of the fuel tank 20.

[0053] Embodiment 2

[0055] As can be seen from the above, by setting the rotatable lubricating wheel assembly 30, when the moving track to be lubricated abuts against the lubricating wheel assembly 30, the lubricating wheel assembly 30 is driven to rotate. The lubricating wheel assembly 30 evenly applies the lubricant in the fuel tank 20 onto the grease, realizing the automatic lubrication of the cantilever beam track, greatly improving the lubrication effect and lubrication efficiency, avoiding the situation that the cantilever beam slips difficultly due to untimely lubrication, resulting in shutdown, and the automatic lubrication process does not require electricity or hydraulic pressure as the power source, with low cost. In addition, by setting the elastic member 40, a pre-pressure is provided for the lubricating wheel assembly 30 to ensure that the lubricating wheel assembly 30 can abut tightly against the track to be lubricated and prepare for lubrication.

[0056] It should be noted that the lubricant can be grease or lubricating oil.

A track is provided at the bottom of the cantilever beam body and is movably arranged on the sliding table. The sliding device on the main deck drives the cantilever beam system to move, enabling the cantilever beam system to extend out of the main deck; when the cantilever beam body moves, the bottom of the track serves as a friction surface and needs to be lubricated; there is a distance of 300 - 400 mm between the bottom of the track and the main deck. Therefore, the cantilever beam track lubrication structure can be arranged here. In addition, the specific structure and working principle of the cantilever beam system are all prior arts and will not be elaborated in this application.

[0060] When the elastic member 40 is compressed and deformed under the action of the track to be lubricated, the fuel tank 20 moves downward. By setting the guide post 50, a guiding effect is provided for the movement of the fuel tank 20, ensuring that the fuel tank 20 always moves in the height direction, thereby ensuring the smooth movement of the fuel tank 20.

[0061] It should be noted that a guide hole is provided on the support plate 120, and the guide holes correspond to the guide posts 50 one by one.

[0070] It should also be noted that one end of the support rod 1301 is welded to the bottom plate 110.

[0071] It should also be noted that when adjusting the height of the support plate 120, the plurality of adjusting nuts 1302 should be rotated to the same height as much as possible, so as to ensure the horizontality of the support plate 120.
