[0031] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without any creative work belong to the scope of protection of the present application.

[0032] Please refer to Figures 1-6 The present application provides an embodiment of a lubricating grease recovery device for a jack-up drilling platform sliding system, which comprises a deck 1 for a jack-up drilling platform;

[0033] A sliding box 2 is provided with four groups, and the four groups of sliding boxes 2 are fixedly installed on the deck 1;

[0034] A slide rail 3 is provided with two groups, and the two groups of slide rails 3 are movably installed in the four groups of suspension beam arms 4;

[0035] A suspension beam arm 4 is fixedly installed on the two groups of slide rails 3;

[0036] A lubricating grease recovery assembly is provided with four groups, and the four groups of lubricating grease recovery assemblies are movably installed on the left and right sides of the four groups of sliding boxes 2, respectively. The lubricating grease recovery assembly is used for recycling the excessive lubricating grease on the slide rail 3;

[0037] A fixing assembly is fixedly installed on the lubricating grease recovery assembly, movably inserted into the sliding box 2, and used for quick disassembly and fastening of the lubricating grease recovery assembly and the sliding box 2;

[0038] The smearing assembly is movably installed in the sliding box 2, and the smearing assembly is connected with the lower end of the grease recovery assembly. The smearing assembly is used for recycling the grease recovered by the grease recovery assembly and smearing on the slide rail 3. The device fixes the grease recovery assembly on the left and right sides of the sliding box 2 through the fixing assembly, and tightly connects the grease recovery assembly and the sliding box 2 through the fixing assembly. When the cantilever beam 4 slides on the sliding box 2 through the slide rail 3, the slide rail 3 slides out of the sliding box 2, and the excess grease on the slide rail 3 is scraped by the grease recovery assembly on the left and right ends of the sliding box 2, so as to avoid falling on the deck 1 or into the sea during the movement of the slide rail 3. Finally, the scraped and collected grease in the grease recovery assembly is recycled by the smearing assembly, and the scraped and collected grease is smeared on the slide rail 3, so as to keep the grease on the slide rail 3 to a certain thickness.

[0039] Further, the four groups of grease recovery assemblies each include two groups of collection discs 6 movably installed on the left and right sides of the sliding box 2. The opposite sides of the two groups of collection discs 6 are each provided with a scraper 13. The lower ends of the two groups of collection discs 6 are each fixedly installed with a first pipeline 14. The two groups of openings of the first pipeline 14 are each fixedly installed with a first valve 15 and a second valve 16. This structure is fixedly installed on the left and right sides of the sliding box 2 through the two groups of collection discs 6. When the slide rail 3 slides out of the sliding box 2, the scraper 13 on the collection disc 6 installed on the left and right sides of the sliding box 2 scrapes the excess grease on the slide rail 3, so as to avoid the excess grease on the slide rail 3 from dripping and causing waste of grease and pollution of the environment.

[0040] Further, the distance between the upper end of the scraper 13 and the lower side of the slide rail 3 is three millimeters, and the scraper 13 is inclined. According to the distance between the scraper 13 and the slide rail 3, the scraper 13 can scrape the excess grease on the slide rail 3 and keep the thickness of the grease smeared on the slide rail 3 to three millimeters. The scraped grease flows into the collection disc 6 through the inclined surface on the upper side of the scraper 13.

[0041] Furthermore, the fixing assembly includes four sets of first grooves 5 and two sets of protrusions 7. The four sets of first grooves 5 are opened on the left and right sides of the sliding box 2. The two sets of protrusions 7 are fixed on the side where the collection tray 6 fits with the sliding box 2. Each set of protrusions 7 has a threaded hole 8. Bolts 9 are inserted into the threaded holes 8. The upper and lower ends of the first grooves 5 are symmetrically provided with second grooves 10. The end of the protrusion 7 inserted into the first groove 5 is symmetrically and movably installed with a plug 12. The two sets of plugs 12 are movably inserted into the two sets of second grooves 10. After the two sets of collection trays 6 are inserted into the first grooves 5 through the protrusions 7, the bolts 9 are inserted into the threaded holes 8. When the bolts 9 are inserted into the threaded holes 8, the bolts 9 press the plugs 12 into the second grooves 10, so that the protrusions 7 can be tightly fixed in the first grooves 5, improving the connection and tightness between the collection tray 6 and the sliding box 2.

[0042] Furthermore, springs 11 are installed in both sets of second grooves 10. The two sets of springs 11 abut against the insert block 12. After the bolt 9 is pulled out from the threaded hole 8, the springs 11 in the second groove 10 launch the insert block 12, thereby sliding the insert block 12 into the protrusion 7, so that the collection tray 6 can be removed from the sliding box 2.

[0043] Furthermore, the bolt 9 is tapered at one end of the threaded hole 8, and the two sets of insert blocks 12 are attached to the upper and lower sides of the bolt 9 on opposite sides. This structure is based on the shape of the end of the bolt 9 that is rubbed back into the threaded hole 8, so that when the bolt 9 is inserted into the threaded hole 8, the two sets of insert blocks 12 are inserted on the side that is attached, and the insert blocks 12 can be pushed into the second groove 10.

[0044] Furthermore, the coating assembly includes two sets of second pipes 17, which are fixedly connected to the first pipe 14 at one end where the first valve 15 is installed. The two sets of second pipes 17 are movably inserted into the left and right ends of the sliding box 2. The sliding box 2 has a movable groove 18, the opening of which fits against the slide rail 3. A base plate 19 is movably installed on the lower side of the movable groove 18, and a sponge pad 20 is fixedly installed on the base plate 19. The left and right sides of the sponge pad 20 fit against the second pipes 17. Screws 21 are rotatably installed in both the front and rear ends of the movable groove 18. A first bevel gear 22 is fixedly installed at the lower end of the two sets of screws 21. The lower end of the sliding box 2 contains... A rotating shaft 23 is rotatably mounted, with second bevel gears 24 fixedly mounted on both ends of the shaft 23. The two sets of second bevel gears 24 mesh with the first bevel gear 22. A rotating handle 25 is fixedly mounted on the front end of the rotating shaft 23. The grease collected in the collection tray 6 flows into the sponge pad 20 in the movable groove 18 through the second pipe 17 after the first valve 15 is opened. Then, the rotating shaft 23 drives the two sets of screws 21 to rotate. The rotation of the screws 21 causes the base plate 19 and the sponge pad 20 to rise, so that the grease in the sponge pad 20 is coated on the slide rail 3, which allows the grease to be recycled and improves the utilization rate of the grease.

[0045] Furthermore, the inner wall of the movable groove 18 is U-shaped, and the sponge pad 20 is U-shaped. The sponge pad 20 can slide up and down in the movable groove 18. According to the shape of the inner wall of the movable groove 18 and the sponge pad 20, when the base plate 19 drives the sponge pad 20 to slide upward in the movable groove 18, the movable groove 18 squeezes and applies the grease on the inner wall to the surface of the slide rail 3.

[0046] Furthermore, the lower inner wall of the collection tray 6 is funnel-shaped. This structure, based on the shape of the lower inner wall of the collection tray 6, allows the grease scraped by the scraper 13 to flow and concentrate in one place through the lower inner wall of the collection tray 6 when it enters the collection tray 6. This facilitates the removal and recycling of the grease in the collection tray 6 through the first pipe 14.

[0047] Working principle: When using cantilever arm 4, as Figure 3 , Figure 5 and Figure 6As shown, two groups of collecting trays 6 are attached on the left and right sides of the sliding box 2, and when the two groups of collecting trays 6 are attached on the sliding box 2, the two groups of protrusions 7 attached on one side of the collecting tray 6 are inserted into the first grooves 5, after the protrusions 7 are inserted into the first grooves 5, the bolts 9 are inserted into the threaded holes 8, when the bolts 9 are inserted into the threaded holes 8, one end of the bolt 9 inserted into the threaded hole 8 extrudes the two groups of insertion blocks 12 in the protrusion 7, the two groups of insertion blocks 12 are extruded and slide out, after the insertion block 12 slides out, it is inserted into the second groove 10, that is, the collecting tray 6 is fixed on the sliding box 2, when the collecting tray 6 is taken off, only the bolt 9 is taken out, the insertion block 12 inserted into the second groove 10 is ejected under the elastic force of the spring 11, that is, the collecting tray 6 is taken off from the sliding box 2, when the excessive lubricating grease on the sliding rail 3 is recycled, the sliding rail 3 is driven by the cantilever arm 4 to slide on the sliding box 2, when the sliding rail 3 slides out of the sliding box 2, the scraper 13 on the collecting tray 6 scrapes the excessive lubricating grease on the surface of the sliding rail 3, the lubricating grease scraped by the scraper 13 slides along the upper surface of the scraper 13 and flows into the collecting tray 6, when the lubricating grease needs to be recycled, the first valve 15 or the second valve 16 is opened, so that the lubricating grease entering the collecting tray 6 flows out through the first pipeline 14 connected at the lower end, the lubricating grease flowing in the first pipeline 14 flows out through the two openings of the first valve 15 or the second valve 16 opened, and the lubricating grease flowing out through the opening of the second valve 16 is taken out and recycled, the lubricating grease flowing out through the opening of the first valve 15 enters the second pipeline 17, after flowing into the second pipeline 17, as Figure 4 As shown, the lubricating grease flows out through the second pipeline 17 and enters the movable groove 18, the lubricating grease entering the movable groove 18 penetrates into the sponge pad 20, then the rotating handle 25 is rotated to drive the rotating shaft 23 to rotate, the rotating shaft 23 drives the two groups of second bevel gears 24 to rotate, the two groups of second bevel gears 24 drive the two groups of first bevel gears 22 meshing at the upper end to rotate, the two groups of first bevel gears 22 drive the two groups of screw rods 21 to rotate, the two groups of screw rods 21 drive the bottom plate 19 and the sponge pad 20 to slide upward in the movable groove 18, the upward sliding of the bottom plate 19 and the sponge pad 20 applies the lubricating grease in the sponge pad 20 to the surface of the sliding rail 3, so that the surface of the sliding rail 3 can be kept with a certain amount of lubricating grease, the above is the whole working principle of the present application.
