[0048] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0049] At present, the mining of thin coal seams is mainly based on the longwall mining method, and the scraper is an important conveying equipment for coal transportation in the longwall mining face. In order to meet the needs of mining, the head and tail of the scraper need to be laid with a chute to enter the thin coal seam working face. In the actual underground working face with a long length and complex geological environment, the height of the chute is fluctuating during the mining of thin coal seams due to the continuous changes in the coal seam, and the inclination angle of the head and tail of the scraper also changes accordingly. If the head and tail of the scraper are in a high position for a long time, it is easy to cause the transmission device of the scraper, especially the bearing, to be insufficiently supplied with lubricating oil, which will cause the bearing to be damaged due to lack of lubrication, and seriously affect the service life of the scraper.

[0050] In order to solve at least one of the technical problems existing in the prior art or related art, the utility model provides a lubricating device, which includes an oil tank, a height-adjustable mounting assembly and an oil filling pipeline, wherein the oil tank is used to store lubricating oil; the height-adjustable mounting assembly is connected to the guard plate of the scraper, and the oil tank is installed on the height-adjustable mounting assembly; the height-adjustable mounting assembly is used to adjust the installation height of the oil tank on the scraper; the oil filling pipeline is connected to the oil tank, and is used to transport the lubricating oil in the oil tank to the transmission device of the scraper. The utility model sets the oil tank height-adjustable on the scraper through the height-adjustable mounting assembly, so that the scraper equipped with the lubricating device can lubricate the transmission device under different working conditions, especially when it is located at a position with a large slope, thereby improving the adaptability of the lane of the scraper under different working conditions.

[0051] The lubrication device and the scraper according to some embodiments of the utility model are described below with reference to the accompanying drawings.

[0052] See also Figures 1 to 6 The utility model provides a lubrication device, which is applied to a scraper machine. The lubrication device includes an oil tank 1, a height-adjustable mounting assembly 2 and an oil filling pipeline 3. The oil tank 1 is used to store lubricating oil; the height-adjustable mounting assembly 2 is connected to a guard plate 4 of the scraper machine, and the oil tank 1 is installed on the height-adjustable mounting assembly 2; the height-adjustable mounting assembly 2 is used to adjust the installation height of the oil tank 1 on the scraper machine; the oil filling pipeline 3 is connected to the oil tank 1, and is used to transport the lubricating oil in the oil tank 1 to a transmission device 5 of the scraper machine.

[0053] Here, the guard plate 4 can be located at the head or tail of the scraper, and the height-adjustable mounting assembly 2 can be connected to the guard plate 4 near its top, so that the oil tank 1 connected to the height-adjustable mounting assembly 2 is located above the scraper.

[0054] It should be noted that the transmission device 5 includes a shell, and the components that need to be lubricated by the lubricating oil are located in the shell. One end of the oil filling line 3 can be connected to the bottom of the oil tank 1, and the other end of the oil filling line 3 can be connected to the shell, so that the lubricating oil in the oil tank 1 flows into the shell through the oil filling line 3, thereby lubricating the components in the shell that need to be lubricated by the lubricating oil.

[0055] In this embodiment, the oil tank 1 is height-adjustably mounted on the guard plate 4 of the scraper through the height-adjustable mounting assembly 2, so that the oil tank 1 can be installed at a high position through the height-adjustable mounting assembly 2, so that the oil tank 1 can adapt to the installation position of the scraper under different working conditions; and the lubricating oil in the oil tank 1 is transported to the transmission device 5 of the scraper through the oil filling pipeline 3 connected to the oil tank 1, so that the lubricating oil in the oil tank 1 can lubricate the transmission device 5. It can be seen that the oil tank 1 is height-adjustably mounted on the scraper through the height-adjustable mounting assembly 2, so that the scraper equipped with the lubricating device can lubricate the transmission device 5 under different working conditions, especially when it is located at a position with a large slope, thereby improving the adaptability of the lanes of the scraper under different working conditions.

[0056] In some possible implementations, see Figure 8 The transmission device 5 includes a reducer 501, a bearing 502 and an oil sealing cover 503, and the oil filling pipeline 3 is also connected to the oil sealing cover 503; accordingly, the lubrication device also includes a liquid level sensor 6, which is arranged on the oil sealing cover 503, and the liquid level sensor 6 is used to detect the oil level of the lubricating oil in the transmission device 5.

[0057] Here, one end of the bearing 502 is connected to the reducer 501, and the other end of the bearing 502 is connected to the bearing 502 seat, and then the oil sealing cover 503 is connected to the bearing 502 seat. One end of the oil filling pipeline 3 is connected to the oil tank 1, and the other end of the oil filling pipeline 3 is connected to the oil sealing cover 503. Here, after the lubricating oil in the oil tank 1 flows into the oil sealing cover 503 through the oil filling pipeline 3, the lubricating oil can flow to the surface of the bearing 502 to achieve lubrication of the bearing 502.

[0058] It should be noted that the liquid level sensor 6 is used to detect the oil level of the lubricating oil on the bearing 502 in real time, so as to detect whether the surface of the bearing 502 is lubricated with the lubricating oil.

[0059] In this embodiment, the oil filling pipeline 3 is connected to the oil sealing cover 503, so that the lubricating oil in the oil tank 1 flows to the bearing 502 through the oil filling pipeline 3 and the oil sealing cover 503 in sequence, so as to achieve lubrication of the bearing 502 by the lubricating oil. At the same time, a liquid level sensor 6 is arranged on the oil sealing cover 503, so as to detect the oil level of the lubricating oil in the transmission device 5, especially the oil level of the bearing 502, so that the staff can control the oil filling pipeline 3 to deliver the lubricating oil to the transmission device 5 according to the detection result of the liquid level sensor 6.

[0060] In some possible implementations, the lubrication device also includes a solenoid valve and a control module. The solenoid valve is arranged on the oil filling pipeline 3, and the solenoid valve is used to control the on-off of the oil filling pipeline 3; the control module is electrically connected to the liquid level sensor 6 and the solenoid valve respectively, and the control module is used to receive the oil level information collected by the liquid level sensor 6, and control the opening or closing action of the solenoid valve according to the received oil level information.

[0061] It should be noted that after the control module receives the oil level information collected by the liquid level sensor 6, the control module can compare the oil level information with the highest preset oil level value or the lowest preset oil level value. When the oil level information collected by the liquid level sensor 6 is greater than the highest preset oil level value, the control module controls the solenoid valve to close to stop the lubrication device from injecting oil into the transmission device 5; when the oil level information collected by the liquid level sensor 6 is less than the lowest preset oil level value, the control module controls the solenoid valve to open to start the lubrication device from injecting oil into the transmission device 5.

[0062] In this embodiment, the control module is electrically connected to the liquid level sensor 6 and the solenoid valve respectively, and after the control module receives the oil level information collected by the liquid level sensor 6, the control module controls the opening or closing action of the solenoid valve according to the received oil level information, so as to realize automatic control of the lubrication device to inject oil into the transmission device 5.

[0063] Furthermore, a liquid level display module 7 is provided on the oil sealing cover 503 , and the liquid level display module 7 is used to display the oil level information of the lubricating oil in the transmission device 5 .

[0064] In this embodiment, by providing a liquid level display module 7 on the oil sealing cover 503, the staff can intuitively obtain the oil level information of the lubricating oil through the liquid level display module 7, which is convenient for the staff to read the oil level of the lubricating oil.

[0065] Furthermore, a protective cover 8 is provided on the upper cover of the oil sealing cover 503 , and the protective cover 8 is used to protect the transmission device 5 and the oil filling pipeline 3 .

[0066] It should be noted that the reducer 501 of the transmission device 5 is located on the side of the scraper away from the coal shearer 9 , and therefore, the oil sealing cover 503 is located on the side of the scraper close to the coal shearer 9 .

[0067] In this embodiment, by covering the oil sealing cover 503 with a protective cover 8, the transmission device 5 and the oil injection pipeline 3 located on the side of the scraper close to the coal mining machine 9 can be protected by the protective cover 8 to avoid collision with the coal blocks mined by the coal mining machine 9, thereby improving the service life of the scraper and the oil injection pipeline 3.

[0068] In some possible implementations, the lubrication device also includes a guide tube 10, which is located between the transmission device 5 and the connecting frame 11 of the scraper, and the guide tube 10 is arranged along the width direction of the scraper; the end of the oil filling pipeline 3 away from the oil tank 1 passes through the guide tube 10 and is connected to the transmission device 5.

[0069] It should be noted that the connecting frame 11 is used to connect the transmission device 5 and the frame 12 of the scraper; the two ends of the guide tube 10 are respectively located on the two side parts of the scraper.

[0070] In this embodiment, a guide tube 10 is provided between the connecting frame 11 and the transmission device 5, and the end of the oil filling pipeline 3 away from the oil tank 1 passes through the guide tube 10 and is connected to the transmission device 5. This not only provides an installation position for the oil filling pipeline 3, but also protects the oil filling pipeline 3 located in the guide tube 10 to prevent external objects from colliding with the oil filling pipeline 3.

[0071] Furthermore, the height-adjustable mounting assembly 2 includes a fixed plate 201 and a height-adjusting portion 202, wherein the fixed plate 201 is connected to the guard plate 4 of the scraper; the height-adjusting portion 202 is connected to the oil tank 1; see Figure 7 The height adjustment part 202 is provided with a connection hole group 203, and the connection hole group 203 includes at least two rows of connection holes opened along the height direction. The height adjustment part 202 can be detachably connected to the fixing plate 201 through the cooperation of each row of connection holes in the connection hole group 203 and bolts.

[0072] Here, when connecting the height adjustment part 202 and the fixing plate 201, a connecting hole matching the target height can be selected according to the target height of the oil tank 1, and then the oil tank 1 can be fixed at the position of the target height by matching the bolts with the connecting holes matching the target height.

[0073] In this embodiment, by opening a connection hole group 203 on the height adjustment part 202, and making the connection hole group 203 include at least two rows of connection holes opened along the height direction, and then utilizing the cooperation between the bolts and the connection holes to achieve a height-adjustable connection between the height adjustment part 202 and the fixed plate 201, the oil tank 1 connected to the height adjustment part 202 can be installed at the target height.

[0074] In some possible implementations, the oil tank 1 is connected to a guard plate 4 on a side of the scraper away from the coal mining machine 9 .

[0075] Here, by connecting the oil tank 1 to the guard plate 4 on the scraper away from the coal mining machine 9, it is possible to avoid the oil tank 1 being damaged due to a collision between the oil tank 1 and the coal mining machine 9.
