Description

Technical Field

[0001] This application relates to the field of fuel tank structure technology, and more specifically, to a detachable inverted U-shaped fuel tank structure. Background Technology

[0002] China has abundant coal reserves, and the prevalence of fully mechanized coal mining is relatively high. This mechanized approach not only greatly improves coal mining efficiency but also significantly enhances the safety of coal mine workers. Fully mechanized coal mining, or "comprehensive mining" for short, refers to a highly efficient coal mining process that uses mechanical methods for coal breaking and loading, transports coal via flexible scraper conveyors, and utilizes self-propelled hydraulic supports to support the roof of the working face. Working faces using this equipment and process are typically referred to as "fully mechanized mining faces."

[0003] The main supporting equipment for a fully mechanized mining face includes: a coal mining machine, a flexible scraper conveyor, and a self-propelled hydraulic support, collectively referred to as the "three machines".

[0004] The scraper conveyor is the main transportation equipment in a coal mining face. Besides transporting coal, it also serves as the support and running track for the coal mining machine. The coal mining machine is mounted on the scraper conveyor and is supported by two support slippers on the coal face side and two guide slippers on the goaf side, respectively, resting on the conveyor's trough and rack rails. The guide slippers in the open travel box of the coal mining machine guide the machine along the rack rails. The travel wheels in the open travel box mesh with the rack rails, allowing the coal mining machine to move in the forward or reverse direction of the conveyor.

[0005] Because the lower part of the traveling gearbox is an open transmission and cannot store oil, without lubrication, the traveling wheels and gears will be in constant mesh, causing rapid wear. Therefore, it is essential to install an oil tank for drip lubrication on the upper part of the traveling gearbox. A common practice is manual lubrication, where workers periodically lubricate the traveling wheels and gears. While this method is simple and direct, it has significant limitations, including uneven lubrication, difficulty in maintaining the correct frequency, and inconvenience in operation. Especially in harsh working environments, manual lubrication may not be possible in a timely manner, leading to accelerated equipment wear. Some solutions may use simple drip lubrication devices to provide continuous lubrication, but these simple devices are not easily matched and installed according to the specific equipment of the coal mining machine. Summary of the Invention

[0006] A detachable inverted U-shaped oil tank structure according to an embodiment of this application includes an oil tank body assembly. The oil tank body assembly is welded and has an inverted "U" shape. Two sets of connecting sleeves are welded between the top and bottom of the oil tank body assembly. Each set of connecting sleeves is equipped with mounting screws. A positioning pin is provided at the bottom of the oil tank body assembly. The positioning pin has a central hole for lubricating oil to pass through. The oil tank body assembly is fixed to the traveling part of the coal mining machine by the positioning pin and the two sets of mounting screws.

[0007] Furthermore, an adjusting screw is threaded onto one side of the positioning pin, and the adjusting screw is used to adjust the flow rate of the lubricating oil.

[0008] Furthermore, a second screw plug is installed on the top of the oil tank assembly. The second screw plug has intersecting small holes and a rotating handle is welded to the upper part of the second screw plug.

[0009] Furthermore, three screw-in round oil level indicators are installed on the front panel of the oil tank assembly, and a sealing copper gasket is embedded on one side of each screw-in round oil level indicator.

[0010] Furthermore, a washer is provided at the contact point between the mounting screw and the connecting sleeve.

[0011] Furthermore, a screw plug is also installed on the top of the fuel tank assembly.

[0012] Furthermore, a support sleeve is fitted on the outer side of the positioning pin, and a pair of retaining plates slide on one side of the support sleeve, which fix the upper and lower sides of the adjusting screw.

[0013] Furthermore, a positioning sleeve is fixedly provided on the lower side of the support sleeve, the positioning sleeve is sleeved on the outside of the positioning pin, and an annular piece is provided on the lower side of the positioning sleeve.

[0014] Furthermore, each of the pair of card plates is provided with a slider on one side, and a turntable is provided on one side of the support sleeve. A pair of rotating grooves are provided on the turntable, and the two sliders slide in the pair of rotating grooves respectively. Limiting grooves are symmetrically provided on the inner side of the support sleeve, and the sliders provided on both sides of the card plate slide in the limiting grooves.

[0015] Furthermore, a rod is inserted into one side of the turntable, and a hole is opened on the rod. A sliding hole is opened on one side of the support sleeve. The fixing rod passes through the wall of the sliding hole from top to bottom. When the rod is inserted into the sliding hole, the fixing rod and the hole are engaged.

[0016] 1. The beneficial effects of this application are as follows: The oil tank assembly can be installed on the upper part of the coal mining machine's traveling gearbox using a positioning pin and two mounting screws, making the oil tank assembly easy to assemble and disassemble. Because a connecting sleeve structure is welded between the top and bottom plates of the oil tank, the oil in the tank will not leak out or get on the mounting screws during the assembly and disassembly process. The inverted U-shaped oil tank assembly structure avoids the long lead screw on the upper part of the coal mining machine, facilitating side installation of the long lead screw. The positioning pin at the bottom of the oil tank assembly also functions as an oil dripper, and the flow rate of the lubricating oil is adjusted by the adjusting screw inside the positioning pin, slowly dripping onto the gears of the open traveling gearbox to complete the lubrication of the open gear transmission. This design not only improves the maintenance convenience and work efficiency of the oil tank assembly but also enhances the safety and reliability of equipment operation, while playing a positive role in maintaining the equipment in good working condition.

[0037] Example 1

[0038] The following description, with reference to the accompanying drawings, depicts a detachable inverted U-shaped fuel tank structure according to an embodiment of this application.

[0039] like Figures 1-5As shown, a detachable inverted U-shaped oil tank structure according to an embodiment of this application includes an oil tank body assembly 1. The oil tank body assembly 1 is made by welding and has an inverted "U" shaped design. This unique shape can not only effectively avoid the long screw at the top of the coal mining machine, but also facilitate the installation of the long screw from the side.

[0040] Two sets of connecting sleeves 10 are cleverly welded between the top and bottom of the fuel tank assembly 1. Each set of connecting sleeves 10 is equipped with an M16x240 mounting screw 8. In order to enhance the sealing and stability of the connection, a washer 9 is specially provided at the contact point between the mounting screw 8 and the connecting sleeve 10. In addition, a positioning pin 6 is fitted at the bottom of the fuel tank assembly 1. The positioning pin 6 is precisely installed in the positioning hole on the upper part of the traveling part to ensure the stable installation of the fuel tank assembly 1.

[0041] By using two sets of mounting screws 8 and locating pins 6, the installation and disassembly of the oil tank assembly 1 can be easily completed. This design greatly simplifies the maintenance process and improves work efficiency. It is worth mentioning that, due to the design of the welded connecting sleeve 10, the oil inside the oil tank assembly 1 will not accidentally leak out during the installation and disassembly of the oil tank assembly 1 using the mounting screws 8, and oil contamination of the mounting screws 8 is also avoided, thus maintaining the cleanliness and good working condition of the equipment. This design not only reflects structural simplicity and practicality, but also enhances the safety and reliability of equipment operation, which is of positive significance for extending the service life of the equipment.

[0042] In addition, a small central hole is provided in the positioning pin 6 at the bottom of the oil tank assembly 1. The small central hole has an oil dripping function, so that the lubricating oil in the oil tank assembly 1 can slowly drip onto the gears of the open travel gearbox to complete the lubrication of the open gear transmission.

[0043] Furthermore, a threaded adjusting screw 7 is designed on one side of the locating pin 6, with its end precisely positioned within the center hole of the locating pin 6. By rotating the adjusting screw 7, its position within the center hole can be adjusted, thereby changing the spatial area through which the lubricating oil flows and thus precisely controlling the flow rate of the lubricating oil. This design not only ensures that the lubricating oil can drip onto the gears of the open travel gearbox at an appropriate rate to achieve optimal lubrication, but also facilitates flexible adjustments by maintenance personnel based on actual usage conditions.

[0044] In addition, a second screw plug 5 is installed on the top of the fuel tank assembly 1. The design of the second screw plug 5 is ingenious. Small cross-shaped holes are drilled inside to give it a venting function, effectively preventing inconvenience or oil leakage caused by internal and external pressure differences. To improve the ease of operation, a rotating handle is also welded to the upper part of the second screw plug 5, allowing maintenance personnel to manually and quickly install and remove the second screw plug 5 without the aid of any tools, which greatly improves work efficiency and convenience. At the same time, a first screw plug 4 is also installed on the top of the fuel tank assembly 1, providing additional sealing protection for the fuel tank.

[0045] On the front panel of the oil tank assembly 1, three screw-in circular oil level gauges 3 are carefully installed. Each screw-in circular oil level gauge 3 has a sealing copper gasket 2 embedded on one side, which not only ensures the good sealing performance of the observation window, but also makes it convenient for operators to check the oil level inside the oil tank assembly 1 at any time. This setting not only enhances the safety and reliability of the equipment, but also helps to detect and deal with potential problems in a timely manner, ensuring that the oil tank assembly 1 is always kept in the best working condition.

[0046] Example 2

[0047] Considering that the adjusting screw 7 may loosen or even fall off due to equipment vibration during long-term operation of the coal mining machine, the design based on the above embodiment has been optimized and improved to ensure higher stability and reliability. (Refer to...) Figures 6 to 9 As shown.

[0048] Specifically, a support sleeve 11 is added to the outside of the positioning pin 6. The support sleeve 11 has a ring structure design. One side of the support sleeve 11 is equipped with a pair of sliding clamping plates 14. These two clamping plates 14 are respectively clamped on the upper and lower sides of the adjusting screw 7, thereby effectively enhancing the stability of the adjusting screw 7 and preventing it from shifting or accidentally falling off due to long-term vibration of the equipment. This design not only improves the stability of the adjusting screw 7, but also ensures the long-term effectiveness of the lubricating oil flow rate adjustment function.

[0049] To further improve the stability of the support sleeve 11, a positioning sleeve 12 is fixedly installed on the lower side of the support sleeve 11. The positioning sleeve 12 also adopts a ring design and is fitted on the outside of the positioning pin 6. The positioning sleeve 12 and the positioning pin 6 can be firmly connected by an appropriate fixing method. In addition, an annular piece 13 is provided at the bottom of the positioning sleeve 12. The function of this annular piece 13 is to seal the contact area between the positioning pin 6 and the positioning hole on the travel box, effectively preventing dust and other impurities from entering and ensuring the cleanliness and tightness of the connection.

[0050] By firmly fixing the positioning sleeve 12 to the traveling box with bolts, the overall installation stability of the oil tank assembly 1 is greatly improved, and the adjusting screw 7 is effectively positioned, preventing accidental movement during machine operation. This design optimization not only enhances the safety and reliability of the equipment but also provides convenient conditions for subsequent maintenance, making the overall structure more reasonable and compact, adapting to the requirements of complex and changing working environments, and extending the service life of the equipment.

[0051] To ensure that the pair of locking plates 14 can quickly and accurately position the adjusting screw 7, a slider 15 is provided on one side of each locking plate 14. These sliders 15 cooperate with the rotating grooves 17 on the turntable 16 mounted on one side of the support sleeve 11. Specifically, a pair of rotating grooves 17 are opened on the turntable 16, and the two sliders 15 slide in the corresponding rotating grooves 17 respectively. The ingenious design of the sliders 15 is that their ends have specific dimensions, which not only ensures that the sliders 15 can slide freely in the rotating grooves 17, but also prevents accidental separation between the turntable 16 and the sliders 15.

[0052] When the turntable 16 is rotated, the slider 15 is restricted to slide within the rotating groove 17. This mechanism drives the clamping plate 14 to move along a predetermined trajectory, thereby achieving rapid and accurate positioning of the adjusting screw 7. This design not only improves operating efficiency but also enhances the stability and reliability of the system.

[0053] To further enhance the stability of the clamping plate 14, symmetrical limiting grooves 20 are formed on the inner side of the support sleeve 11. The sliding strips 21 on both sides of the clamping plate 14 slide precisely within these limiting grooves 20. This structure not only precisely limits the sliding direction of the clamping plate 14, ensuring that it moves along the expected path, but also effectively prevents accidental separation between the clamping plate 14 and the support sleeve 11, increasing the durability and safety of the entire device.

[0054] In summary, through the synergistic effect of components such as slider 15, turntable 16 and limiting groove 20, this design significantly improves the efficiency and accuracy of the clamping plate 14 in positioning the adjusting screw 7, while greatly enhancing the stability and reliability of the overall structure.

[0055] To further improve the fixing effect of the card plate 14 on the adjusting screw 7 and to ensure the stability and reliability of the entire system, a plug rod 18 is designed on one side of the turntable 16. The plug rod 18 has a plug hole 19, while a sliding hole 22 is provided on one side of the support sleeve 11. In addition, a fixing rod 23 is also provided, which can penetrate the wall of the sliding hole 22 from top to bottom.

[0056] When it is necessary to use the rotating turntable 16 to fix the adjusting screw 7 in place by the clamping plate 14, the operation procedure is as follows: First, rotate the turntable 16 to accurately position and fix the adjusting screw 7 in place by the clamping plate 14. Next, rotate the insert rod 18 to the position corresponding to the sliding hole 22 and insert it into the sliding hole 22. At this point, the key step is to insert the fixing rod 23 from above the sliding hole 22 and make it pass through the insertion hole 19 on the insert rod 18. This design not only ensures that the turntable 16 will not rotate or loosen accidentally after positioning, but also greatly enhances the fixing effect of the clamping plate 14 on the adjusting screw 7.

[0057] In summary, the working principle of a detachable inverted U-shaped oil tank structure is as follows: the oil tank assembly 1 is installed on the upper part of the traveling box of the coal mining machine using mounting screws 8 and positioning pins 6. Lubricating oil inside the oil tank assembly 1 drips into the gear section of the traveling box through the central hole of the positioning pins 6. The flow rate of the lubricating oil is adjusted by rotating the adjusting screws 7. After the adjusting screws 7 are adjusted to the correct position, the turntable 16 is rotated. Since the slider 15 is connected to the clamping plate 14 and the slider 15 is located in the rotating groove 17 on the turntable 16, when the turntable 16 is rotated, the slider... Block 15 slides in the rotating groove 17. As the turntable 16 rotates, the movement of the slider 15 in the rotating groove 17 will drive the clamping plate 14 to move along a predetermined path. When the clamping plate 14 is slid to the designated position, it will engage with the upper and lower sides of the adjusting screw 7, thereby forming a stable clamping of the adjusting screw 7 and preventing it from loosening or shifting due to equipment vibration or other reasons. Insert the insertion rod 18 into one side of the turntable 16 and rotate the insertion rod 18 to the position corresponding to the sliding hole 22 on the support sleeve 11, and then insert the insertion rod 18 into the sliding hole 22. Next, insert the fixing rod 23 from above, so that it passes through the insertion hole 19 on the insertion rod 18. This ensures that the turntable 16 will not rotate or loosen accidentally, thereby maintaining the stable clamping of the adjusting screw 7 by the clamping plate 14. Furthermore, the positioning sleeve 12 is fixed to the traveling box by bolts to enhance the stability of the oil tank assembly 1.
