Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coal loading car chain lubrication technology, specifically relating to a tamping coal loading car and its transmission chain lubrication device. Background Technology
[0002] The coal loading transmission chain is an indispensable core component of the tamping coal loading car. It bears a huge load and operates frequently during use. Due to this high-intensity and high-frequency use, the wear problem of the coal loading chain has become an urgent problem to be solved. In order to effectively extend the service life of the chain and prevent equipment failure and production interruption caused by excessive wear, it is particularly important to lubricate the chain scientifically and reasonably.
[0003] Existing lubrication methods mainly include drip lubrication and spray lubrication. Drip lubrication applies lubricating oil to the chain in the form of drops through a specific device. However, this method has obvious limitations, namely uneven lubrication. In actual operation, some areas often receive too much lubricating oil, causing unnecessary waste, while other areas do not receive sufficient lubrication due to insufficient oil, thus aggravating chain wear. Spray lubrication uses atomization of lubricating oil, spraying fine oil droplets evenly onto the chain surface through a spray device. Although this method improves the uniformity of lubrication to some extent, the strong diffusion of oil mist often leads to a large amount of lubricating oil being wasted in the air, which not only increases costs but also causes some environmental pollution. In summary, there is an urgent need for a lubrication device for a tamping coal loading car and its drive chain. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0020] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a tamping coal loading car and its transmission chain lubrication device.
[0021] On one hand, this utility model discloses a lubrication device for the transmission chain of a tamping coal loading car. The transmission chain 1 is disposed between two sprockets 2. The lubrication device for the transmission chain of the tamping coal loading car includes an oil tank 3, an oil pump 4 connected to the oil tank 3, and multiple lubrication components 6 disposed on the transmission chain 1. The lubrication components 6 are disposed near the sprockets 2 to effectively lubricate the transmission chain 1 during operation. The lubrication components 6 are connected to the oil pump 4 through a pipeline 5. The lubrication components 6 include a housing 61 and an oil-absorbing medium 62 disposed in the housing 61. The housing 61 has corresponding chain-passing holes at both ends. The chain 1 passes through two chain holes in sequence. The oil-absorbing medium 62 is placed between the box 61 and the transmission chain 1, so that the transmission chain 1 comes into contact with the oil-absorbing medium 62 during operation. The oil-absorbing medium 62 absorbs and stores lubricating oil. The box 61 is provided with an oil injection hole 63, which is matched with the connector at one end of the pipeline 5, so as to ensure that the lubricating oil can be easily injected into the box 61 and absorbed by the oil-absorbing medium 62. The pipeline 5 is connected to the oil injection hole 63. When the transmission chain 1 is running, the friction between it and the oil-absorbing medium 62 will cause the lubricating oil stored in the oil-absorbing medium 62 to be evenly coated on the surface of the chain, achieving effective lubrication.
[0022] Furthermore, in the transmission chain lubrication device for tamping coal loading car of this utility model, a coal support plate 7 is provided above the transmission chain 1, a coal cake 8 is loaded on the top of the coal support plate 7, a baffle 9 is provided at one end of the top of the coal support plate 7, and the coal cake 8 is placed between the coal support plate 7 and the baffle 9. This arrangement not only ensures the stable loading of the coal cake 8, but also avoids the coal cake 8 from scattering or shifting during operation.
[0023] As one specific implementation, in the transmission chain lubrication device for tamping coal loading cars of this utility model, the box 61 is designed to be detachable. More specifically, the box 61 is divided into an upper box and a lower box, which are connected by fastening bolts. Of course, the upper box and the lower box can also be connected by a snap-fit connection. With this configuration, when it is necessary to replace the oil absorption medium 62 or clean the box 61, the operator can easily disassemble the box 61 to perform the operation, thereby reducing maintenance costs and time.
[0024] In one specific embodiment, in the transmission chain lubrication device for tamping coal loading car of this utility model, the number of lubrication components 6 is 2 to 6. More specifically, the number of lubrication components 6 is 2, and the two lubrication components 6 are respectively set on the transmission chain 1 near the sprocket 2. Of course, in actual use, the number of lubrication components 6 needs to be set according to the specific working conditions such as the size of the transmission chain 1.
[0025] In one specific embodiment, in the lubrication device for the transmission chain of the tamping coal loading car of this utility model, the oil-absorbing medium 62 is an oil-absorbing sponge. Of course, the oil-absorbing medium 62 can also be made of other porous materials. With this setting, the oil-absorbing sponge has good oil absorption and oil retention properties, which can ensure the stable storage and uniform application of lubricating oil. At the same time, the oil-absorbing sponge also has certain wear resistance and corrosion resistance, which can maintain a long service life in harsh working environments.
[0026] On the other hand, this utility model also provides a tamping coal loading car, which includes the above-mentioned transmission chain lubrication device.
[0027] The working principle of the transmission chain lubrication device for a tamping coal loading car is as follows: The housing 61 is set at a designated position on the transmission chain 1. The lubricating oil stored in the oil tank 3 is transferred to the pipeline 5 by the oil pump 4. The lubricating oil flows through the pipeline 5 to the injection hole, where it is absorbed and stored by the oil absorption medium 62. When the tamping coal loading car is loading coal, the transmission chain 1 rotates counterclockwise around the sprocket 2 through the drive device, sending the coal cake 8 into the carbonization chamber. After loading is completed, the transmission chain 1 rotates clockwise around the sprocket 2 through the drive device, returning to the initial position. During this process, the transmission chain 1 reciprocates through each housing 61. As the chain passes through the housing 61 and comes into contact with the oil absorption medium 62, the lubricating oil absorbed in the oil absorption medium 62 can fully and evenly lubricate the transmission chain 1 without wasting lubricating oil.
[0028] In summary, compared with the prior art, the tamping coal loading car and its transmission chain lubrication device of this utility model have the following advantages and beneficial effects:
[0029] This device achieves effective lubrication of the transmission chain 1 during operation by setting multiple lubrication components 6 on the transmission chain 1 and using the oil-absorbing medium 62 to absorb and store lubricating oil. This ensures that the lubricating oil is evenly applied to the surface of the transmission chain 1, reducing friction and wear between the transmission chain 1 and the sprocket 2, extending the service life of the transmission chain 1. Moreover, the effective lubrication of the transmission chain 1 ensures its smooth and efficient operation, thereby improving the coal loading efficiency of the tamping coal loading car. Furthermore, the box 61 is designed to be detachable, making it easy for operators to replace the oil-absorbing medium 62 or clean the box 61, reducing maintenance and time costs, and demonstrating good practicality.
