Description

Technical Field

[0001] This utility model belongs to the field of gantry crane technology, specifically a self-lubricating device for gantry crane base. Background Technology

[0002] Gantry cranes are often used in other sectors such as ports and shipping, railways and rail transit, steel and heavy machinery manufacturing, warehousing and logistics centers, and water conservancy and hydropower projects.

[0003] The gantry crane base serves as the core support and operating foundation for the gantry crane (gantry crane). As a large lifting equipment in ports and docks, the gantry crane base must withstand huge loads and frequent movement and vibration during operation. Therefore, it has extremely high requirements for the lubrication system. The self-lubricating device achieves automatic lubrication through special design, which can effectively solve the shortcomings of traditional manual lubrication.

[0004] In existing technologies, long-term observation has revealed that when existing self-lubricating devices are used below -50℃, the viscosity of the base oil in ordinary greases (such as lithium-based greases) increases sharply at low temperatures, and the soap-based structure shrinks, causing the grease to lose its fluidity and making it difficult to be delivered to friction parts (such as bearings and gear meshing surfaces) through the oil circuit of the self-lubricating device. This leads to lubrication failure, exacerbates mechanical wear, and increases the wear rate due to direct metal-to-metal dry friction between moving parts. This may cause serious failures such as journal scoring and gear tooth breakage, thereby shortening the equipment life. Therefore, a self-lubricating device for the base of a gantry crane is proposed to address the above problems. Utility Model Content

[0025] Please see Figures 1-4This utility model provides a self-lubricating device for a gantry crane base, including an oil storage tank 1; a base 10 is provided at the bottom of the oil storage tank 1; multiple sets of support legs 11 are fixedly connected to the bottom end of the base 10; a cover 12 is provided at the top of the oil storage tank 1; an oil guiding assembly 13 is provided on the side wall of the cover 12; an installation groove 14 is opened on the side wall of the oil storage tank 1; multiple sets of heating assemblies 15 are fixedly connected to the inner side of the installation groove 14; a fixing groove 16 is opened on the inner side of the base 10; fixing rods 17 are symmetrically fixedly connected to the side wall of the fixing groove 16; a servo motor 18 is fixedly connected to the side wall of the fixing rod 17; the servo... A rotating shaft 19 is fixedly connected to the output end of the servo motor 18; the rotating shaft 19 passes through the side wall of the oil storage tank 1 and is rotatably connected to it; multiple sets of stirring rods 110 are symmetrically fixed to the side wall of the rotating shaft 19; a temperature sensor 111 is fixedly connected to the inner wall of the oil storage tank 1; the temperature sensor 111 is electrically connected to the heating component 15; multiple sets of reinforcing ribs 112 are fixedly connected to the side wall of the oil storage tank 1; during operation, the support legs 11 can support the base 10, the base 10 can support the oil storage tank 1, the oil storage tank 1 can store lubricating oil, and the cover 12 can support the oil guiding component 13. The oil guiding assembly 13 delivers lubricating oil to the parts requiring lubrication. The mounting groove 14 supports the heating assembly 15. When the temperature sensor 111 detects a temperature below -50°C, the heating assembly 15 operates to heat the solidified lubricating oil in the oil storage tank 1. Simultaneously, the fixing groove 16 supports the fixing rod 17, which in turn supports the servo motor 18. The servo motor 18 rotates, driving the rotating shaft 19, which in turn drives the stirring rod 110, further agitating the lubricating oil in the oil storage tank 1. The heated lubricating oil is stirred and mixed to ensure uniform mixing within the oil storage tank 1. The reinforcing ribs 112 enhance the stability of the oil storage tank 1. This design not only simplifies and facilitates operation but also heats the lubricating oil when used in low-temperature environments, reducing the likelihood of solidification. Simultaneously, the heating process stirs and mixes the lubricating oil, ensuring uniform mixing of the molten oil. This facilitates self-lubrication of components, reduces direct metal-to-metal dry friction between moving parts, lowers wear, and extends the equipment's service life.

[0026] Furthermore, such as Figures 1-4As shown, a guide rail 2 is fixedly connected to the side wall of the oil storage tank 1; multiple sets of sliding rods 21 are slidably connected to the inner side of the guide rail 2; a connecting frame 22 is fixedly connected to the side wall of the sliding rod 21; insulation cotton 23 is fixedly connected to the side wall of the connecting frame 22; a first connecting strip 24 is fixedly connected to one end of the insulation cotton 23; a second connecting strip 25 is fixedly connected to the other end of the insulation cotton 23. The first connecting strip 24 and the second connecting strip 25 are connected by adhesive. During operation, the guide rail 2 supports the sliding rod 21, the sliding rod 21 supports the connecting frame 22, and the connecting frame 22 connects the insulation cotton 23. When the heating component 15 is heating... When the solidified lubricating oil in the oil storage tank 1 is heated, the operator pulls the slide bar 21 to move it along the guide rail 2, which causes the connecting frame 22 to move the insulation cotton 23 to wrap around the outer wall of the oil storage tank 1, thus achieving the function of heat preservation. Moreover, by connecting the first connecting belt 24 and the second connecting belt 25 together, the operator can ensure that the insulation cotton 23 completely wraps around the outer wall of the oil storage tank 1, improving the sealing performance. Through this design, when the solidified lubricating oil in the oil storage tank 1 is heated, it can achieve the function of heat preservation, thereby reducing heat loss, reducing resource consumption, and further improving the heating effect.

[0027] Furthermore, such as Figures 1-4 As shown, a first mixing plate 3 is symmetrically fixed to the side wall of the rotating shaft 19; a rotating rod 31 is symmetrically rotatably mounted on the side wall of the oil storage tank 1; a second mixing plate 32 is symmetrically fixed to the side wall of the rotating rod 31. During operation, when the rotating shaft 19 rotates, it can drive the first mixing plate 3 to rotate. When the first mixing plate 3 rotates to the position of the second mixing plate 32, it can move the second mixing plate 32 to rotate. The second mixing plate 32 can be connected through the rotating rod 31. With this design, when the stirring rod 110 stirs and mixes, it can drive the first mixing plate 3 and the second mixing plate 32 to stir and mix the lubricating oil solidified at the bottom of the oil storage tank 1. With this design, when stirring the solidified lubricating oil in the oil storage tank 1, it can stir and mix the lubricating oil at the bottom of the oil storage tank 1, thereby improving the mixing effect of the lubricating oil and improving the quality of the lubricating oil.

[0028] Furthermore, such as Figures 1-4As shown, the top of the oil storage tank 1 is symmetrically provided with positioning grooves 4; a first magnetic block 41 is fixedly connected to the inner side of the positioning groove 4; a second magnetic block 42 is symmetrically fixedly connected to the bottom of the cover 12; the second magnetic block 42 and the first magnetic block 41 are connected by magnetic connection; during operation, the operator pulls the cover 12, thereby pulling the second magnetic block 42 out of the positioning groove 4, so that the cover 12 can be disassembled. When the cover 12 is installed, the operator inserts the second magnetic block 42 into the positioning groove 4. When the second magnetic block 42 is close to the first magnetic block 41, it can automatically connect, thereby achieving a quick positioning function. This design facilitates the operator's installation and disassembly of the cover 12, and when the cover 12 is installed, it can achieve a quick positioning function, thereby facilitating the operator's cleaning of the inside of the oil storage tank 1.

[0029] Furthermore, such as Figures 1-4 As shown, an observation window 5 is fixed to the side wall of the oil storage tank 1; the observation window 5 is made of transparent material; during operation, the observation window 5 allows the staff to easily observe the internal condition of the oil storage tank 1, and this design facilitates the staff to observe the state of the lubricating oil inside the oil storage tank 1, thus improving its practicality.

[0030] Furthermore, such as Figures 1-4 As shown, a rubber pad 6 is provided at the bottom of the support leg 11; the rubber pad 6 is connected to the support leg 11 by adhesive bonding; during operation, the rubber pad 6 can increase the friction with the ground, and this design can increase the friction with the ground, thereby improving the stability of the base 10.

[0031] Working principle: The support leg 11 supports the base 10, which in turn supports the oil storage tank 1, which stores lubricating oil. The cover 12 supports the oil guiding assembly 13, which guides the lubricating oil to the parts requiring lubrication. The mounting groove 14 supports the heating assembly 15. When the temperature sensor 111 detects a temperature below -50℃, the heating assembly 15 operates, heating the solidified lubricating oil in the oil storage tank 1. Simultaneously, the fixing groove 16 supports the fixing rod 17. The fixed rod 17 supports the servo motor 18. The servo motor 18 rotates, driving the rotating shaft 19 to rotate. The rotating shaft 19 then drives the stirring rod 110 to rotate, further stirring and mixing the heated lubricating oil in the oil storage tank 1, ensuring uniform mixing. The reinforcing rib 112 improves the stability of the oil storage tank 1. The guide rail 2 supports the sliding rod 21, which in turn supports the connecting frame 22. The connecting frame 22 connects to the insulation cotton 23. When the heating component 15 is heating... When the solidified lubricating oil inside the oil storage tank 1 is heated, the operator pulls the slide bar 21 to move it along the guide rail 2, causing the connecting frame 22 to move the insulation cotton 23 to wrap around the outer wall of the oil storage tank 1, thus providing insulation. Furthermore, by connecting the first connecting strap 24 and the second connecting strap 25 together, the operator ensures that the insulation cotton 23 completely wraps around the outer wall of the oil storage tank 1, improving the sealing. When the rotating shaft 19 rotates, it drives the first mixing plate 3 to rotate. When the first mixing plate 3 rotates to the position of the second mixing plate 32, it can actuate the second mixing plate. The composite plate 32 rotates, and the second mixing plate 32 can be connected via the rotating rod 31. By pulling the cover 12, the second magnetic block 42 can be pulled out of the positioning groove 4, allowing the cover 12 to be disassembled. When installing the cover 12, the second magnetic block 42 is inserted into the positioning groove 4. When the second magnetic block 42 is close to the first magnetic block 41, they automatically connect, achieving rapid positioning. The observation window 5 allows the operator to observe the inside of the oil storage tank 1, and the rubber pad 6 increases friction with the ground.
