[0030] A rigging lubrication device provided in this embodiment, refer to Figures 1 - 5As shown in the figure, it includes a first rotating shaft 1. A fixed pulley 11 is rotatably connected to the first rotating shaft 1. The first rotating shaft 1 is connected to the supporting columns 2 on both sides. Above the first rotating shaft 1, there is a second rotating shaft 3. A lubricating wheel 31 is rotatably connected to the second rotating shaft 3. The second rotating shaft 3 is movably connected to the supporting columns 2 on both sides. Above the lubricating wheel 31, there is a lubricating box 4. A long slot 41 is opened at the bottom of the lubricating box 4. The upper part of the lubricating wheel 31 extends into the lubricating box 4 through the long slot 41. The bottom end of the outer circumferential surface of the lubricating wheel 31 is in contact with the steel wire rope 5 wound around the fixed pulley 11. A cover plate 42 is provided on the upper part of the lubricating box 4. The lubricating box 4 is filled with lubricating grease.

[0031] In the above embodiment, the lubricating box 4 is filled with lubricating grease, and a cover plate 42 is provided on the upper part of the lubricating box 4. The cover plate 42 is used to block external dust and impurities from entering the lubricating box 4, avoiding dust and impurities from mixing into the lubricating grease and thus affecting the lubricating effect of the lubricating grease. A fixed pulley 11 is rotatably connected to the first rotating shaft 1. A steel wire rope 5 is wound around the fixed pulley 11. The first rotating shaft 1 is connected to the supporting columns 2 on both sides. A lubricating wheel 31 is rotatably connected to the second rotating shaft 3. The lubricating wheel 31 extends into the lubricating box 4 through the long slot 41 at the bottom of the lubricating box 4. The bottom end of the outer circumferential surface of the lubricating wheel 31 is in contact with the steel wire rope 5 wound around the fixed pulley 11. When the steel wire rope 5 is driven to rotate on the fixed pulley 11, the rotation of the steel wire rope 5 will drive the lubricating wheel 31 to rotate. The extending end of the lubricating wheel 31 in the lubricating box 4 rotates, that is, the lubricating wheel 31 rotates to wind out the lubricating grease in the lubricating box 4, and then through the contact between the outer circumferential surface of the lubricating wheel 31 and the steel wire rope 5, the lubricating grease is smeared on the steel wire rope 5, realizing the lubrication and maintenance of the steel wire rope 5 during the traction and sliding process of the steel wire rope 5 on the fixed pulley 11, which is beneficial to improving the service life of the rigging, reducing the operation cost of the rigging equipment. Compared with manually applying grease on the surface of the steel wire rope 5, it improves the lubrication and maintenance efficiency, reduces the manual participation, and is also beneficial to improving the safety factor of production operations. Further, the outer width of the lubricating wheel 31 is smaller than the outer width of the fixed pulley 11 to ensure that the lubricating grease wound out by the outer circle of the lubricating wheel 31 can completely contact the steel wire rope 5 on the fixed pulley 11, avoiding waste of lubricating grease due to vacancies when the fixed pulley 11 contacts the steel wire rope 5.

[0032] In an embodiment of the present application, refer to Figure 2 , Figure 3 As shown in the figure, a slot hole 21 is provided on the supporting column 2. The second rotating shaft 3 is movably connected to the supporting column 2 through the slot hole 21. Counterweight blocks 6 are sleeved at both ends of the second rotating shaft 3.

[0033] In the above embodiment, in order to prevent the contact surface between the lubricating wheel 31 and the steel wire rope 5 from slipping, counterweight blocks 6 are sleeved at both ends of the second rotating shaft 3. The downward fall of the counterweight blocks 6 pulls the second rotating shaft 3 to move downward in the slot hole 21, so that the contact surface between the lubricating wheel 31 and the steel wire rope 5 is tightened, thereby increasing the smoothness of the rotation of the steel wire rope 5 driving the lubricating wheel 31, which is beneficial to improving the lubrication efficiency of the steel wire rope 5. Further, the counterweight blocks 6 are sleeved at both ends of the second rotating shaft 3 through collar rings. When the second rotating shaft 3 rotates, the collar rings do not rotate with the rotating shaft, preventing the counterweight blocks 6 from interfering with the rotation of the second rotating shaft 3, which is beneficial to improving the smoothness of the rotation of the second rotating shaft 3.

[0034] In one embodiment of the present application, referring to Figure 4 As shown, a sliding groove 22 is provided on the outer wall of the support column 2, and the counterweight block 6 is slidably connected to the sliding groove 22 along the setting direction of the sliding groove 22.

[0035] In the above embodiment, the counterweight block 6 is slidably connected to the sliding groove 22 along the vertical setting direction of the sliding groove 22. The sliding groove 22 is used to limit the downward fall direction of the counterweight block 6, preventing the counterweight block 6 from rotating with the second rotating shaft 3 and also preventing the counterweight block 6 from falling and injuring the staff, which is beneficial to improving the safety of the device.

[0036] In one embodiment of the present application, referring to Figure 4 As shown, scraping plates 311 are provided on both sides of the lubricating wheel 31.

[0037] In the above embodiment, the scraping plates 311 are connected to the bottom surface of the lubricating box 4, and the tip ends of the scraping plates 311 are close to the sides of the lubricating wheel 31. When the lubricating wheel 31 rotates, the scraping plates 311 are used to prevent the lubricating grease in the lubricating box 4 from being carried out from the long strip holes 41 at the bottom of the lubricating box 4 by the rotation of the side surface of the lubricating wheel 31. The scraping plates 311 are used to scrape off the excess lubricating grease on the sides of the lubricating wheel 31, avoiding waste of lubricating grease, which is beneficial to improving the use efficiency of the lubricating grease.

[0038] In one embodiment of the present application, referring to Figure 2 As shown, fine grooves are provided on the outer circumferential surface of the lubricating wheel 31.

[0039] In the above embodiment, the fine grooves provided on the outer circumferential surface of the lubricating wheel 31 can, on the one hand, increase the friction force between the lubricating wheel 31 and the steel wire rope 5, which is beneficial to improving the smoothness of the rotation of the lubricating wheel 31. On the other hand, the fine grooves can store a part of the lubricating grease. When the lubricating wheel 31 is in contact with the steel wire rope 5, the lubricating grease is smeared on the surface of the steel wire rope 5, improving the lubrication efficiency of the steel wire rope 5.

[0040] In one embodiment of the present application, referring to Figure 5 As shown, the outside of the lubricating box 4 is coated with a heat insulation layer.

[0041] In the above embodiments, the performance of the grease is greatly affected by temperature. In a cold environment, the grease may become too viscous, affecting the lubrication effect; in a high-temperature environment, the grease will decompose or fail prematurely. The heat-insulating layer is used to keep the grease in the lubricating tank 4 within an appropriate working temperature range, ensuring the lubricity and stability of the grease.

[0042] In an embodiment of the present application, referring to Figure 5 As shown, a filler port 421 is provided on the upper end surface of the cover plate 42 of the lubricating tank 4, and a flip cover 422 is installed above the filler port 421.

[0043] In the above embodiment, opening the flip cover 422 can be used to add grease to the lubricating tank 4, which is more convenient than opening the cover plate 42, and the state of the grease in the lubricating tank 4 can also be observed through the filler port 421.

[0044] During the actual use of the present application: a fixed pulley 11 is connected to the first rotating shaft 1, a steel wire rope 5 is wound around the fixed pulley 11, and the first rotating shaft 1 is connected to the support columns 2 on both sides. A lubricating wheel 31 is rotatably connected to the second rotating shaft 3. The lubricating wheel 31 extends into the lubricating tank 4 through the long hole 41 at the bottom of the lubricating tank 4, and the bottom end of the outer circumferential surface of the lubricating wheel 31 is in contact with the steel wire rope 5 wound around the fixed pulley 11. When the steel wire rope 5 is driven to rotate on the fixed pulley 11, the rotation of the steel wire rope 5 will drive the lubricating wheel 31 to rotate. The extending end of the lubricating wheel 31 rotates in the lubricating tank 4, that is, the lubricating wheel 31 rotates to roll out the semi-solid paste-like grease in the lubricating tank 4, and then the grease is applied to the steel wire rope 5 through the contact between the outer circumferential surface of the lubricating wheel 31 and the steel wire rope 5, realizing the lubrication and maintenance of the steel wire rope 5 during the traction and sliding of the steel wire rope 5 on the fixed pulley 11. In addition, lithium-based grease, yellow glycerin, etc. can be selected as the grease.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
