Description

Technical Field

[0001] The utility model relates to the technical field of aircraft refueling equipment, in particular to a quick disassembly and assembly device for a lateral bearing of a platform gantry of a pipeline refueling vehicle. Background Art

[0002] The pipeline aircraft refueling truck is one of the special equipment for refueling civil aviation aircraft. During the refueling process, the refueler needs to frequently use the pipeline refueling truck lifting platform to operate. Lateral bearings installed in the lateral channel steel are provided between adjacent gantries. Due to the frequent use of the lifting platform operation, the lateral bearings in the lateral channel steel not only play a role in reducing friction, but also offset the pressure on the side wall caused by the shaking of the lifting platform. Frequent and long-term use causes the lateral bearings in the lifting platform channel steel to wear seriously and lose too quickly.

[0003] In practice, damaged lateral bearings require replacement every one to two years on average. Because the platform mast is large and heavy, with multiple layers and bearings on both sides, existing systems require dismantling each mast structure from the outside of the platform. This is a highly risky operation, and each replacement process takes approximately four to five hours, with high labor costs.

[0004] For this purpose, a quick disassembly and assembly device for the lateral bearings of the platform mast of a pipeline refueling vehicle is proposed. Utility Model Content

[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0051] The embodiment of the utility model proposes a rapid disassembly and assembly device for the lateral bearing of the platform gantry of a pipeline refueling vehicle. Through the mounting hole 102, the bearing bracket assembly 200 can be quickly installed in the working position within the movable gap 101 between adjacent gantries 100. Compared with the existing replacement and installation operations of bearings, the present technical solution can realize rapid disassembly and installation, greatly improves the processing speed, and reduces maintenance costs, thereby achieving the purpose of reducing costs and increasing efficiency.

[0052] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0053] like Figures 1 to 4As shown, according to an embodiment of the present application, a quick disassembly and assembly device for the lateral bearing of the platform gantry of a pipeline refueling truck is proposed, including: parallel gantries 100, with a movable gap 101 formed between adjacent gantries 100, and a mounting hole 102 connected to the movable gap 101 formed on the gantries 100; a bearing support assembly 200, which can be detachably mounted in the movable gap 101 through the mounting hole 102, and is used to make the two gantries 100 slide relative to each other; a locking bolt 300, which can be detachably mounted in the mounting hole 102 and is connected to the bearing support assembly 200, and is used to make the bearing support assembly 200 be in the movable gap 101.

[0054] The pipeline refueling vehicle platform gantry lateral bearing quick disassembly and assembly device provided in the embodiment of the present application includes a gantry 100, a bearing support assembly 200 and a locking bolt 300, wherein an active gap 101 for installing the bearing support assembly 200 is formed between adjacent gantries 100, and adjacent gantries 100 slide with each other through the bearing support assembly 200. During long-term use, due to the wear of the bearing support assembly 200, when installing and replacing, the bearing support assembly 200 enters the active gap 101 through the mounting hole 102 set on the gantry 100, and is then installed in the mounting hole 102 through the locking bolt 300. The mounting hole 102 is closed by the locking bolt 300, so that the bearing support assembly 200 can be stably installed in the active gap 101 and will not fall out of the active gap 101 through the mounting hole 102, thereby ensuring that the adjacent gantries 100 slide with each other stably. At the same time, the locking bolt 300 is connected to the bearing support assembly 200, so that the bearing support assembly 200 is further stably installed in the active gap 101.

[0055] Exemplarily, a mounting hole 102 is formed on the side wall of a gantry 100, and the bearing support assembly 200 is installed on the gantry 100 having the mounting hole 102 through the mounting hole 102, thereby achieving the fixing of the bearing support assembly 200 relative to the gantry 100 having the mounting hole 102, and adjacent gantries 100 are in sliding contact with the bearing support assembly 200.

[0056] To sum up, when it is necessary to replace the bearing support assembly 200 in the gap space 101, the locking bolt 300 installed on the mounting hole 102 is removed. At this time, the movable gap 101 is connected to the external space through the mounting hole 102, and the bearing support assembly 200 can be moved to the external space through the mounting hole 102, thereby achieving quick disassembly. When installation is required, it is only necessary to install the qualified bearing support assembly 200 in the gap space 101 through the mounting hole 102, and then lock the mounting hole with the locking bolt 300 to achieve the installation of the bearing support assembly 200. Compared with the existing replacement and installation operations of bearings, this technical solution can achieve rapid disassembly and installation, greatly improve the processing rate, and at the same time reduce maintenance costs, thereby achieving the purpose of reducing costs and increasing efficiency.

[0057] like Figures 1 to 4 As shown, in some examples, the locking bolt 300 includes a bolt body 310 threadedly mounted in the mounting hole 102 .

[0058] In this technical solution, locking bolt 300 includes a bolt body 310 threadedly mounted within mounting hole 102, ensuring that bearing support assembly 200 is stably mounted within movable gap 101. Its threaded connection with mounting hole 102 ensures a tight fit, preventing loosening or falling out. During installation, bolt body 310 is rotated to gradually screw into mounting hole 102, tightly connecting to bearing support assembly 200. This connection method is not only simple and convenient to operate, but also provides a reliable fixing effect.

[0059] For example, the length and diameter of the bolt body 310 are allocated according to the size of the mounting hole 102 and the installation requirements of the bearing support assembly 200. When the bolt body 310 is screwed into the mounting hole 102, its end can fully contact the bearing support assembly 200 to ensure the stability of the connection.

[0060] The bolt body 310 of the locking bolt 300 is installed in the mounting hole 102 through a thread, providing a reliable fixing method for the installation of the bearing bracket assembly 200. When the bearing bracket assembly 200 needs to be replaced, it is only necessary to unscrew the bolt body 310 to conveniently remove the bearing bracket assembly 200 from the movable gap 101, which not only improves the disassembly and assembly efficiency, but also reduces maintenance costs, providing a strong guarantee for the normal operation of the pipeline refueling truck platform gantry.

[0061] like Figures 1 to 4 As shown, in some examples, the bolt body 310 is away from the surface of the movable gap 101, and a locking groove 301 is formed between the bolt body 310 and the gantry 100; the locking bolt 300 also includes: a fixing screw 320, which is threadedly installed in the locking groove 301.

[0062] In this technical solution, the locking groove 301 formed between the bolt body 310 and the gantry 100 provides a specific position for the installation of the fixing screw 320, further enhancing the fixing effect of the locking bolt 300; wherein the locking bolt 300 also includes a fixing screw 320 threadedly installed in the locking groove 301. When the bolt body 310 is threadedly installed in the mounting hole 102, the fixing screw 320 is screwed into the locking groove 301. At this time, due to the obstruction of the fixing screw 320, the rotation between the bolt body 310 and the gantry 100 is restricted, so that the bolt body 310 is fixed relative to the gantry 100, which can effectively prevent the bolt body 310 from loosening or accidentally unscrewing during use.

[0063] Exemplarily, the length and diameter of the fixing screw 320 are adapted to the locking groove 301. When installing the fixing screw 320, it is necessary to ensure that it is screwed in to a moderate depth, which can provide sufficient fixing force without causing damage to the bolt body 310 or the gantry 100; the locking bolt 300 is composed of a bolt body 310 and a fixing screw 320. The bolt body 310 is threadedly installed in the mounting hole 102 to achieve preliminary fixation of the bearing support assembly 200, while the fixing screw 320 is threadedly installed in the locking groove 301, further enhancing the fixing effect of the locking bolt 300, ensuring that the bearing support assembly 200 is stably installed in the movable gap 101 and will not loosen or fall off due to external force or vibration. This structure not only improves the reliability and stability of the rapid disassembly and assembly device of the lateral bearing of the pipeline refueling vehicle platform gantry, but also provides convenience for the normal operation and maintenance of the equipment.

[0064] like Figures 1 to 4 As shown, in some examples, the locking groove 301 includes: a first locking semicircle 3011 formed on the surface of the locking bolt 300 ; and a second locking semicircle 3012 formed on the surface of the gantry 100 .

[0065] In this technical solution, the locking groove 301 includes a first locking semicircle 3011 and a second locking semicircle 3012, wherein the first locking semicircle 3011 is formed on the surface of the locking bolt 300, and the second locking semicircle 3012 is formed on the surface of the gantry 100. The curvature and size of the first locking semicircle 3011 on the surface of the locking bolt 300 are adapted to the curvature and size of the second locking semicircle 3012, thereby enabling the first locking semicircle 3011 and the second locking semicircle 3012 to be combined into the locking groove 301.

[0066] The second locking semicircle 3012 is formed on the surface of the gantry 100, and its position and size correspond to the first locking semicircle 3011. During the processing, the surface of the gantry 100 is finely processed to ensure the flatness and accuracy of the second locking semicircle 3012. This ensures that when the locking bolt 300 is installed on the gantry 100, the first locking semicircle 3011 and the second locking semicircle 3012 can fit tightly to form a stable locking groove 301.

[0067] Exemplarily, there are multiple first locking semicircles 3011, and the multiple first locking semicircles 3011 are arranged in a circular shape with equal distances on the locking bolt 300 with the axis of the locking bolt 300 as the center. When the locking bolt 300 is rotated to different angles, the second locking semicircle 3012 can be closed with the nearest first locking semicircle 3011 to form a locking groove 301.

[0068] For example, when installing the locking bolt 300, it is necessary to ensure that the first locking semicircle 3011 and the second locking semicircle 3012 are accurately aligned so that the fixing screw 320 can be smoothly installed in the locking groove 301. At the same time, in order to improve the sealing and stability of the locking groove 301, a sealing gasket or coating can be added to the contact surface of the first locking semicircle 3011 and the second locking semicircle 3012.

[0069] To sum up, the locking groove 301 includes a first locking semicircle 3011 and a second locking semicircle 3012. These two semicircles are respectively formed on the surfaces of the locking bolt 300 and the gantry 100. Through tight fit, a stable locking groove 301 is formed, which provides a reliable position for the installation of the fixing screw 320. This structure not only improves the fixing effect of the locking bolt 300, but also enhances the overall stability and reliability of the pipeline refueling truck platform gantry lateral bearing quick disassembly and assembly device.

[0070] like Figure 1 As shown, in some examples, the pipeline refueling vehicle platform gantry lateral bearing quick disassembly and assembly device further includes: a fixed shell 400, which is arranged in the above-mentioned movable gap 101, and one end of the above-mentioned fixed shell 400 is fixedly installed on one of the above-mentioned gantry 100.

[0071] In this technical solution, the rapid disassembly and assembly device of the lateral bearing of the pipeline refueling vehicle platform gantry also includes a fixed shell 400 arranged in the movable gap 101. Its external size and structure match the shape and size of the movable gap 101, and can be tightly installed in the movable gap 101 without loosening or shaking. One end of the fixed shell 400 is fixedly installed on a gantry 100. For example, during the installation process, by adopting reliable connection methods such as welding, bolt connection, etc., it is ensured that the connection between the fixed shell 400 and the gantry 100 is firm and reliable. The fixed installation method can withstand large external forces and vibrations, ensuring that the fixed shell 400 will not separate from the gantry 100 during use.

[0072] Exemplarily, the fixed shell 400 is a cylindrical fixed shell, whose axis is perpendicular to the moving direction of the gantry 100, and the large bearing is coaxially installed on the outside of the fixed shell 400. The shape and length of the internal space of the fixed shell 400 are adapted to the bearing support assembly 200 to ensure that the bearing support assembly 200 will not rotate about its own axis.

[0073] For example, the length and width of the fixed shell 400 can be set according to the size of the movable gap 101 and actual usage requirements, and its surface can be treated, such as spraying an anti-corrosion coating, adding anti-slip textures, etc., to improve the performance and service life of the fixed shell 400. At the same time, a sealing gasket or rubber strip can be set at the connection between the fixed shell 400 and the gantry 100 to enhance the sealing of the connection and prevent impurities such as dust and moisture from entering the movable gap 101 and affecting the normal operation of the bearing support assembly 200.

[0074] The fixed shell 400 in the quick disassembly and assembly device of the lateral bearing of the pipeline refueling vehicle platform gantry is set in the movable gap 101, and one end is fixedly installed on a gantry 100. The installation of the fixed shell 400 can provide additional protection and support for the bearing bracket assembly 200, thereby improving the overall stability and reliability of the device.

[0075] like Figures 1 to 4 As shown, in some examples, the above-mentioned bearing support assembly 200 includes: a side bearing support 210, which is slidably installed in the above-mentioned fixed shell 400 along the axis of the above-mentioned fixed shell 210, and a mounting groove 201 is formed at the end of the above-mentioned side bearing support 210 away from the above-mentioned locking bolt 300; a rolling bearing 220, which is rotatably installed in the above-mentioned mounting groove 201 and is used for rolling contact with the adjacent above-mentioned gantry 100.

[0076] In this technical solution, the bearing support assembly 200 includes a side bearing support 210 and a rolling bearing 220. The side bearing support 210 is slidably installed in the fixed shell 400 along the axis of the fixed shell 210. The side bearing support 210 can be made of high-strength and wear-resistant materials, and its external structure is consistent with the internal structure of the fixed shell 400 to ensure that it can slide smoothly in the fixed shell 400; an installation groove 201 is formed at the end of the side bearing support 210 away from the locking bolt 300, and the rolling bearing 220 is installed in the installation groove 201. The inner wall of the installation groove 201 is smooth and flat, which provides good support and positioning for the installation of the rolling bearing 220.

[0077] The rolling bearing 220 is rotatably installed in the mounting groove 201 and is used for rolling contact with the adjacent gantry 100, which can effectively reduce friction and wear and improve the operating efficiency and reliability of the device. For example, the rolling bearing 220 can be installed by interference fit or press fit to ensure that it is firm and reliable in the mounting groove 201 and will not loosen or fall off.

[0078] When the platform gantry of the pipeline refueling truck is in operation, the side bearing bracket 210 is fixed in the fixed shell 400 along with the gantry 100, and the rolling bearing 220 is in rolling contact with the adjacent gantry 100, reducing friction resistance and making the movement of the gantry more stable and smooth. At the same time, the rotation of the rolling bearing 220 can also withstand a certain lateral force, ensuring the stability and safety of the gantry.

[0079] For example, the depth and width of the mounting groove 201 should match the size of the rolling bearing 220 to ensure the firmness and stability of the installation. The model and specifications of the rolling bearing 220 can be selected according to factors such as the load-bearing capacity and movement speed of the gantry 100 to meet the usage requirements under different working conditions.

[0080] The bearing support assembly 200 includes a side bearing support 210 and a rolling bearing 220. The side bearing support 210 is slidably installed in the fixed shell 400, so that the bearing support assembly 200 can be quickly installed in the working position of the gap space 101. At the same time, the side bearing support 210 provides installation and support for the rolling bearing 220. The rolling bearing 220 is rotatably installed in the installation groove 201 and is in rolling contact with the adjacent gantry 100, reducing friction resistance and improving the movement performance and reliability of the gantry.

[0081] like Figure 1 As shown, in some examples, the pipeline refueling truck platform gantry lateral bearing quick disassembly and assembly device also includes: a limiter 500, which is fixedly installed on the inner wall of the above-mentioned fixed shell 400 and inserted into the above-mentioned mounting groove 201, and is used to limit the above-mentioned side bearing bracket 210 from rotating about the axis of the above-mentioned fixed shell 400.

[0082] In this technical solution, the pipeline refueling truck platform gantry lateral bearing quick disassembly and assembly device also includes a limiter 500 fixedly installed on the inner wall of the fixed shell 400. When the side bearing bracket 210 is installed in the fixed shell 400, the limiter 500 is inserted into the installation groove 201. For example, the size and shape of the installation groove 201 match the limiter 500, so that the limiter 500 can be smoothly inserted therein. At the same time, when the limiter 500 is inserted into the installation groove 201, it can be in close contact with the side bearing bracket 210 to form a stable limiter structure to limit the rotation of the side bearing bracket 210.

[0083] The limiter 500 is used to limit the side bearing bracket 210 from rotating about the axis of the fixed shell 400. During the operation of the pipeline refueling truck platform gantry, the side bearing bracket 210 needs to slide in the fixed shell 400, but should not rotate. The presence of the limiter 500 effectively prevents the side bearing bracket 210 from rotating, ensuring the normal operation of the device. The limiter 500 limits the rotational freedom of the side bearing bracket 210 by cooperating with the mounting groove 201, so that it can only slide along the axis of the fixed shell 400, thereby ensuring stable rolling contact between the rolling bearing 220 and its adjacent gantry.

[0084] For example, the shape of the limiting member 500 can be set according to actual conditions, for example, it can be square, round or other special shapes, and the depth and angle of its insertion into the mounting groove 201 can also be adjusted to achieve the best limiting effect. At the same time, in order to improve the wear resistance and service life of the limiting member 500, its surface can be specially treated, such as quenching, chrome plating, etc.

[0085] To sum up, the limiter 500 in the quick disassembly and assembly device of the lateral bearing of the pipeline refueling vehicle platform gantry is fixedly installed on the inner wall of the fixed shell 400 and inserted into the installation groove 201. The limiter 500 can effectively limit the side bearing bracket 210 from rotating about the axis of the above-mentioned fixed shell 400, thereby ensuring the normal operation and stability of the device.

[0086] In some examples, the locking bolt 300 is threadedly connected to the bearing support assembly 200 .

[0087] In this technical solution, the locking bolt 300 is threadedly connected to the bearing support assembly 200, and a threaded hole matching the locking bolt 300 is formed on the bearing support assembly 200. When the locking bolt 300 is screwed into the threaded hole of the bearing support assembly 200, the threads between the two engage with each other to form a firm connection. The threaded connection has the following advantages: first, the connection is reliable and can withstand large axial forces and shear forces, ensuring that the bearing support assembly 200 will not loosen or fall off during operation. Second, it is easy to install and disassemble. When the bearing support assembly 200 needs to be repaired or replaced, it can be easily removed by screwing the locking bolt 300. In addition, the threaded connection also has a certain adjustment function. The position and tightness of the bearing support assembly 200 can be adjusted by screwing the locking bolt 300 to meet different working requirements.

[0088] Illustratively, the threaded hole is formed on an end surface of the side bearing bracket 210 adjacent to the bolt body 310 .

[0089] For example, when installing the locking bolt 300 , it should be screwed according to the specified torque to ensure that the tightness of the connection is moderate, neither too loose to cause loosening nor too tight to damage the threads or parts.

[0090] In summary, the locking bolt 300 and the bearing bracket assembly 200 are connected by a threaded connection, which has the advantages of being reliable and easy to install and disassemble, and provides a strong guarantee for the normal operation of the pipeline refueling vehicle platform gantry lateral bearing quick disassembly and assembly device.

[0091] like Figure 1 and Figure 4 As shown, in some examples, the pipeline refueling truck platform gantry lateral bearing quick disassembly and assembly device also includes: an oil delivery circuit 600, which is arranged in the above-mentioned locking bolt 300 and the above-mentioned bearing support assembly 200. When the above-mentioned locking bolt 300 is connected to the above-mentioned bearing support assembly 200, the input end of the above-mentioned oil circuit 600 is formed on the end face of the above-mentioned locking bolt 300 away from the above-mentioned bearing support assembly 200, and the output end of the above-mentioned oil circuit 600 is connected to the above-mentioned rolling bearing 220, and is used for delivering lubricating substances to the above-mentioned rolling bearing 220 through the above-mentioned oil circuit 600.

[0092] In this technical solution, the pipeline refueling truck platform gantry lateral bearing quick disassembly and assembly device also includes a delivery oil circuit 600 arranged in the locking bolt 300 and the bearing bracket assembly 200. The delivery oil circuit 600 can ensure that the lubricating material can be accurately and efficiently delivered to the rolling bearing 220.

[0093] For example, the rolling bearing 220 may be selected but is limited to a needle roller type rolling bearing 220 .

[0094] When the locking bolt 300 is connected to the bearing support assembly 200, the input end of the oil circuit 600 is formed on the end face of the locking bolt 300 away from the bearing support assembly 200. The position of the input end of the oil circuit 600 is convenient for connection with an external lubricating material supply source; the output end of the oil circuit 600 is connected to the rolling bearing 220, and the position of the output end is precisely aligned with the rolling bearing 220, ensuring that the lubricating material can be directly delivered to the key parts of the bearing. The oil circuit 600 has two output ends, which correspond to the two ends of the bearing pin of the rolling bearing 220. When the rolling bearing 220 rotates, the lubricating material is evenly distributed on the axis of the rolling bearing 220 as it rotates, providing a lubricating effect for the rolling bearing 220.

[0095] For example, the lubricant may be lubricating oil, grease, or other suitable lubricants. These lubricants can effectively reduce friction and wear of the rolling bearing 220 during operation, reduce energy loss, and extend the service life of the bearing. At the same time, the lubricant can also cool the bearing to prevent damage due to overheating.

[0096] For example, in order to ensure that the oil delivery circuit 600 is unobstructed, a filter can be set in the oil circuit to prevent impurities from entering the rolling bearing 220. At the same time, according to different working conditions and requirements, different types of lubricants can be selected, and the delivery amount and delivery frequency of the lubricant can be adjusted to achieve the best lubrication effect.

[0097] Exemplarily, the input end of the oil circuit 600 is formed on the bolt body 310, wherein the portion of the oil circuit 600 located on the bolt body 310 is arranged in the screw of the bolt body 310, wherein the screw is threadedly connected to the screw hole on the side bearing bracket 210, and the screw is a hollow structure. Lubricating oil can be used to enter the screw hole through the oil circuit 600 in the screw. At the same time, the oil circuit 600 located in the side bearing bracket 210 is connected to the screw hole. When the bolt body 310 and the side bearing bracket 210 are threadedly connected together, the oil circuit 600 is unobstructed.

[0098] To sum up, the oil delivery circuit 600 in the quick disassembly and assembly device of the lateral bearing of the pipeline refueling truck platform gantry is arranged in the locking bolt 300 and the bearing bracket assembly 200. The oil delivery circuit 600 can effectively deliver lubricating substances to the rolling bearing 220, thereby improving the working performance and service life of the bearing, and providing reliable guarantee for the normal operation of the pipeline refueling truck platform gantry.

[0099] like Figures 1 to 4As shown, in some examples, the port diameter of the input end of the above-mentioned oil circuit 600 is a first diameter, the cross-sectional diameter in the above-mentioned oil circuit 600 is a second diameter, and the above-mentioned first diameter is smaller than the above-mentioned second diameter; the pipeline refueling vehicle platform gantry lateral bearing quick disassembly and assembly device also includes: a blocking ball 700, which is slidably installed in the above-mentioned oil circuit 600 and close to the side of the input end of the above-mentioned oil circuit 600, and the diameter of the above-mentioned blocking ball 700 is between the above-mentioned first diameter and the above-mentioned second diameter; an elastic member 800, which is arranged in the above-mentioned oil circuit 600 and is connected to the above-mentioned blocking ball 700, and is used to make the above-mentioned blocking ball 700 fit tightly with the input end of the above-mentioned oil circuit 600.

[0100] In this technical solution, the port diameter of the input end of the oil circuit 600 is a first diameter, and the cross-sectional diameter in the oil circuit 600 is a second diameter, and the first diameter is smaller than the second diameter; the pipeline refueling vehicle platform gantry lateral bearing quick disassembly and assembly device also includes a sealing ball 700 slidably installed in the oil circuit 600 and close to one side of the input end of the oil circuit 600. The installation position of the sealing ball 700 is close to the input end, and can respond to the pressure change of the external lubricating material supply source in time to achieve rapid sealing and opening of the oil circuit, and the diameter of the sealing ball 700 is between the first diameter and the second diameter. The diameter of the sealing ball 700 cannot be too large, so as to avoid the lubricating material being unable to flow normally through the oil circuit 600, nor can it be too small, otherwise the input end of the oil circuit 600 cannot be effectively sealed, resulting in leakage of the lubricating material. By setting the diameter of the sealing ball 700 between the first diameter and the second diameter, it can be ensured that it plays the best role in the oil circuit.

[0101] The quick disassembly and assembly device of the lateral bearing of the platform mast of the pipeline refueling truck also includes an elastic part 800, which is arranged in the oil circuit 600 and connected to the blocking ball 700. For example, the elastic part 800 can be selected but not limited to a spring. Its function is to provide a continuous pressure for the blocking ball 700 so that the blocking ball 700 fits tightly with the input end of the oil circuit 600. The elastic coefficient of the elastic part 800 needs to be selected according to specific working conditions and requirements to ensure that a good sealing effect can be maintained under different pressures.

[0102] When an external lubricating material supply source inputs lubricating material into the oil circuit 600, the pressure overcomes the elastic force of the elastic part 800, pushing the blocking ball 700 to slide inside the oil circuit 600, opening the input end, and allowing the lubricating material to smoothly enter the oil circuit 600. When the lubricating material supply stops, the elastic force of the elastic part 800 pushes the blocking ball 700 back to the input end, thereby blocking the oil circuit 600 and preventing the lubricating material from leaking.

[0103] At the same time, the installation position and preload of the elastic member 800 can be adjusted according to actual conditions to optimize the blocking effect of the blocking ball 700. In addition, for example, a filter device can be provided at the input end of the oil circuit 600 to prevent impurities from entering the oil circuit and affecting the normal operation of the blocking ball 700 and the elastic member 800.

[0104] In summary, the input port diameter and internal cross-sectional diameter of oil passage 600 in the quick assembly and disassembly device for the lateral bearing of the pipeline refueling vehicle platform mast, as well as the structure of the sealing ball 700 and elastic member 800, together form an efficient and reliable lubricant delivery system. This system ensures that lubricant is accurately delivered to rolling bearing 220 when needed, while effectively preventing lubricant leakage, providing a strong guarantee for the normal operation of the pipeline refueling vehicle platform mast.
