Coal mining machine can move back and forth on the coal mining working face through the drive of traveling axle, and complete a series of complex operations such as coal mining, loading and transportation. The performance of traveling axle directly affects the stability and operation efficiency of coal mining machine. Therefore, in the process of coal mining, the design and maintenance of traveling axle are particularly important. Traveling axle is widely used in various types of coal mining machines, including continuous coal mining machine, hydraulic support coal mining machine, etc., suitable for different mine environments and mining conditions.

Over-lubrication not only wastes lubricating grease, but also may cause the lubricating grease to accumulate inside the travel axle, increasing the difficulty of cleaning and maintenance, and affecting the normal operation of the equipment. On the contrary, insufficient lubrication will increase the friction between the travel axle and the bearing, accelerate wear, and in severe cases may cause equipment failure or even shutdown, affecting the continuity and efficiency of coal mining work.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: an automatic lubrication device for a walking wheel shaft of a coal mining machine, comprising a shaft body 1, an outer wall of the shaft body 1 is provided with a mounting assembly, the mounting assembly is used to mount the shaft body 1 as a whole, an oil guide groove 3 is opened inside the shaft body 1, an oil pot 4 is slidably connected inside the shaft body 1, a fixed pipe 5 is slidably connected inside the shaft body 1, a fixed sleeve 6 is fixedly connected inside the fixed pipe 5, a limiting sleeve 7 is fixedly connected inside the fixed sleeve 6, a fixed flange 8 is fixedly connected to the outer wall of the fixed pipe 5, the outer wall of the fixed flange 8 is fixedly connected to the inside of the shaft body 1, and the fixed flange 8 is threadedly connected inside An adjusting bolt 9, one end of which is fixedly connected to a rotary handle 10, and the other end of which is rotatably connected to a sealing plug 11. A spring 12 is sleeved on the outer wall of the adjusting bolt 9, and the outer wall of the sealing plug 11 is slidably connected to the inside of the limiting sleeve 7. A sealing ring 13 is fixedly connected to the outer wall of the sealing plug 11, and a limiting ball 14 is fixedly connected to the outer wall of the sealing plug 11; the mounting assembly comprises a mounting flange 2, the inside of which is fixedly connected to the outer wall of the shaft body 1; one end of the spring 12 is fixedly connected to the inside of the fixing flange 8, and the other end of the spring 12 is fixedly connected to the outer wall of the sealing plug 11;

[0024] Specifically, the adjusting bolt 9 is rotated by turning the handle 10, and the contact between the adjusting bolt 9 and the inside of the fixed flange 8 is thereby driven to drive the sealing plug 11 to slide outward. This action compresses the spring 12 and gradually increases the distance between the sealing plug 11 and the limiting sleeve 7. During the adjustment process, the sealing ring 13 and the limiting ball 14 ensure that the sealing plug 11 can maintain good sealing during the sliding process. The sealing ring 13 can effectively prevent the leakage of the lubricant, while the limiting ball 14 limits the depth of the sealing plug 11 sliding out of the limiting sleeve 7 to ensure precise lubricant flow control. When the sealing plug 11 slides out of the limiting sleeve 7, the lubricant begins to flow out of the oil pot 4, and the outflow amount can be controlled by further adjustment of the handle 10. This not only improves the adjustability of the device, allowing the operator to adjust the amount of lubricant used according to specific needs, but also expands the scope of application of the device in different working environments and application scenarios.

[0025] Reference Figure 1 , Figure 2 and Figure 4 The outer wall of the oil pot 4 is fixedly connected with a fixing plate 15, and the interior of the fixing plate 15 is fixedly connected with a base 16; the interior of the base 16 is rotatably connected with a rotating shaft 17, and the outer wall of the rotating shaft 17 is fixedly connected with a clamping block 18; the interior of the shaft body 1 is fixedly connected with a mounting sleeve 20, and a spring 2 19 is arranged inside the mounting sleeve 20, and both ends of the spring 2 19 are fixedly connected to the outer wall of the clamping block 18; the interior of the mounting sleeve 20 is slidably connected with a push plate 21, and the outer wall of the push plate 21 is fixedly connected with a top plate 22; the interior of the mounting sleeve 20 is provided with a spring 3 23, one end of the spring 3 23 is fixedly connected to the interior of the mounting sleeve 20, and the other end of the spring 3 23 is fixedly connected to the outer wall of the top plate 22;

[0026] Specifically, by pressing both sides of the push plate 21 at the same time, the top plate 22 is driven to compress the spring three 23. At the same time, the push plate 21 can push the block 18, so that the two blocks 18 can rotate around the rotating shaft 17, thereby compressing the spring two 19 between the blocks 18. As the spring two 19 is compressed, the block 18 can eventually slide completely out from the inside of the mounting sleeve 20, and then slide the fixing plate 15 outward, which allows the oil pot 4 to easily slide out from the inside of the shaft body 1, which not only improves the convenience of operation, but also significantly extends the service life of the device, ensures the safety and reliability of the oil pot 4 replacement process, and improves the maintenance efficiency of the device.

[0027] Working principle: when the amount of oil flowing out of the oil pot 4 needs to be regulated, the adjusting bolt 9 is driven to rotate inside the fixed flange 8 by turning the rotary handle 10, and the sealing plug 11 is driven to slide outward, thereby compressing the spring 12 and continuously increasing the distance between the sealing plug 11 and the limiting sleeve 7, wherein the sealing ring 13 and the limiting ball 14 can assist the sealing plug 11 to perform better sealing until the sealing plug 11 slides out of the limiting sleeve 7, thereby achieving the effect of regulating the outflow of the lubricant, improving the adjustability of the device, and expanding the scope of application of the device. When the oil pot 4 is to be disassembled, the push plates 21 on both sides are pressed simultaneously to drive the top plate 22 to compress the spring three 23. At the same time, the push plate 21 can push the block 18, so that the two blocks 18 can rotate around the rotating shaft 17, and then compress the spring two 19 therebetween, until the block 18 can completely slide out of the interior of the mounting sleeve 20, and then the fixing plate 15 is slid outward, so that the oil pot 4 can slide out from the interior of the shaft body 1, thereby achieving the effect of quickly disassembling and replacing the oil pot 4, improving the convenience of the device and extending the service life of the device.
