[0040] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In order to better understand the present invention, the above contents are described in detail below in conjunction with specific embodiments.

[0042] Please see attached Figure 1-Figure 19 The embodiment of the present invention provides a quick-detachable wheel hub structure of a track translation trolley in a tunnel, comprising: a steel wheel 1, a steel shaft 2 is passed through the middle of the steel wheel 1; a steel frame 1 4, a steel frame 2 5 is provided on the outside of the steel wheel 1, and the two are connected by two steel frames 4 6; and the steel wheel 1 is in a closed space formed by the steel frame 1 4, the steel frame 2 5 and the two steel frames 4 6; a steel frame 3 3 is provided with two steel frames 3, and the two steel frames 3 3 are respectively installed between the steel frame 1 4 and the steel frame 2 5, and the two sides of the steel shaft 2 are respectively between the steel frame 1 4 and the steel frame 3 3 and between the steel frame 2 5 and the steel frame 3 3.

[0043] In the present invention, the steel wheel 1 is supported by the steel shaft 2, and the steel shaft 2 is connected to the steel wheel 1 through a double-row tapered roller bearing, which ensures the smooth rotation of the steel wheel 1 on the shaft. The steel frame 1 4 and the steel frame 2 5 are respectively arranged on both sides of the steel wheel 1, and are connected through two steel frames 4 6 to form a closed structural space, fixing the steel wheel 1 in the middle, and providing sufficient supporting force. The two steel frames 3 3 are respectively installed between the steel frame 1 4 and the steel frame 2 5, which play a role in reinforcing and stabilizing the entire structure. The two sides of the steel shaft 2 are respectively between the steel frame 1 4 and the steel frame 3 3 and between the steel frame 2 5 and the steel frame 3 3, ensuring the stable operation of the steel wheel 1 and sharing the load.

[0044] The steel shaft 2 is connected to the steel wheel 1 using double-row tapered roller bearings. Cylinders are provided on both sides of the steel shaft 2, and a plane is provided on the outer wall of the cylinder on one side of the steel shaft 2. Both sides of the steel shaft 2 are locked by retaining springs to enable the steel shaft 2 to move left and right in the bearings.

[0045] In the present invention, the steel shaft 2 is connected to the steel wheel 1 through a double-row tapered roller bearing, so it can provide a larger load-bearing capacity, ensure stable operation under heavy loads and impact loads, and can automatically adjust the axis deviation to make the bearing force uniform and reduce wear and fatigue. Cylinders are provided on both sides of the steel shaft 2 to cooperate with the inside of the bearing to enhance stability. The outer wall of the cylinder on one side of the steel shaft 2 is provided with a plane design, which helps to dock and fix with other components, ensuring the accuracy and reliability of assembly. At the same time, both sides of the steel shaft 2 are locked by retaining springs to prevent the steel shaft 2 from moving left and right in the bearing, ensuring a stable connection between the steel shaft 2 and the steel wheel 1, and improving the stability and durability of the entire structure.

[0046] The steel frame 1 4 and the steel frame 3 3 as well as the steel frame 2 5 and the steel frame 3 3 are riveted by bolts 7, and the bolts 7 are hexagon socket bolts. Both sides of the two steel frames 4 6 are connected to the two sides of the side surfaces close to the steel frame 1 4 and the steel frame 2 5 by double-sided submerged arc welding.

[0047] In the present invention, the steel frame 1 4 and the steel frame 3 3, as well as the steel frame 2 5 and the steel frame 3 3 are riveted by bolts 7, and the bolts 7 are hexagon socket bolts. This connection method can provide high-strength and reliable fixation, ensuring that they will not loosen or fall off under heavy-load working environments. The use of hexagon socket bolts simplifies the installation process, while providing sufficient tightening force to facilitate rapid disassembly and maintenance of the equipment. In order to further enhance the stability of the connection, the two sides of the two steel frames 4 6 are firmly connected to the adjacent sides of the steel frame 1 4 and the steel frame 2 5 by double-sided submerged arc welding. Double-sided submerged arc welding has strong welding strength and durability, and can maintain the stability of the structure under high load conditions, ensuring that the entire hub structure will not deform or loosen during long-term use.

[0048] The steel frame 1 4 , the steel frame 2 5 and the two steel frames 3 are all provided with threaded holes 9 inside, and the bolts 7 are located in the threaded holes 9 .

[0049] In the present invention, the steel frame 1 4, the steel frame 2 5 and the two steel frames 3 are all provided with threaded holes 9 inside, and the bolts 7 are installed therein through the threaded holes 9. It is ensured that the bolts 7 can be accurately fixed at the predetermined position, and a more stable connection method is provided. The existence of the threaded holes 9 not only improves the reliability of the connection, but also facilitates subsequent maintenance and replacement operations. Through this structure, the bolts 7 can effectively withstand the force under high load conditions, and ensure the tightness between the connecting parts to avoid loosening or deformation. It also simplifies the overall assembly and disassembly process, improves the manufacturing and maintenance efficiency, and ensures the long-term stable operation of the hub structure.

[0050] A pin shaft 10 is provided inside the cylinder on the other side of the steel shaft 2 , and an oil nozzle 11 and an oil filling hole 12 are provided inside the pin shaft 10 for filling grease through the oil filling hole 12 and the grease nozzle 11 .

[0051] In the present invention, a pin shaft 10 is provided inside the cylinder on the other side of the steel shaft 2, and an oil nozzle 11 and an oil filling hole 12 are provided inside the pin shaft 10. This structure is used to add butter through the oil filling hole 12 and the butter nozzle 11 to ensure the lubrication of the double-row tapered roller bearing between the steel shaft 2 and the steel wheel 1 under high load and long-term operation. Through the oil nozzle 11 and the oil filling hole 12, lubricating oil can be easily injected into the bearing part to reduce friction and wear, thereby extending the service life of the bearing and improving the working efficiency and reliability of the overall structure. It effectively solves the problem of difficult lubrication, reduces the occurrence of mechanical failures, and is also convenient for daily maintenance and maintenance, further improving the operating stability of the track translation trolley in the tunnel.

[0052] The steel frame 1 4 has the same size as the steel frame 2 5 , and the two steel frames 3 3 and the two steel frames 4 6 have the same size.

[0053] In the present invention, the size of steel frame 1 4 is the same as that of steel frame 2 5, and the size of two steel frames 3 3 and two steel frames 4 6 is the same. This design ensures the dimensional consistency of the components of the track translation trolley in the tunnel, so that the components can be standardized and unified during installation and later maintenance, thereby improving assembly accuracy and work efficiency. Through unified dimensions, manufacturing errors and mismatch problems are reduced, and the fit between components is tighter, ensuring the stability and reliability of the structure. In addition, the standardized design simplifies the production process, facilitates rapid disassembly and assembly during mass production and component replacement, improves the maintenance efficiency of the entire device, and reduces maintenance costs. This enables the equipment to operate stably for a long time, while improving interchangeability and ease of maintenance during use.

[0054] The top surfaces of steel frame 1 4 and steel frame 2 5 are both provided with mounting holes 8 , and the mounting holes 8 on the top surface of steel frame 2 5 are circular, and the mounting holes 8 on the top surface of steel frame 1 4 are provided with flat surfaces for matching the cylinders provided on both sides of the steel shaft 2 .

[0055] In the present invention, the top surface of steel frame 1 4 and the top surface of steel frame 2 5 are both provided with mounting holes 8, and the mounting holes 8 on the top surface of steel frame 2 5 are circular, and the mounting holes 8 on the top surface of steel frame 1 4 are provided with planes for matching the cylinders provided on both sides of the steel shaft 2. Through this design, the shape and position of the mounting holes accurately match the cylinders on both sides of the steel shaft 2, ensuring the accurate positioning and stable support of the steel shaft 2 between steel frame 1 4 and steel frame 2 5. The circular mounting holes 8 on the top surface of steel frame 2 5 are tightly matched with the cylinders of the steel shaft 2, which can effectively prevent the deviation or instability of the steel shaft 2, thereby improving the working performance and bearing capacity of the steel shaft and the steel wheel. At the same time, the matching of the plane mounting holes 8 on the top surface of steel frame 1 4 with the cylinders enhances the installation accuracy, ensures the tightness and stability of the entire structure, and avoids the deviation or looseness caused by installation errors. Not only does it optimize the assembly process, but it also improves the overall stability and service life of the trolley.

[0056] The steel wheel 1, the steel shaft 2, the steel frame three 3, the steel frame one 4, the steel frame two 5 and the steel frame four 6 are made of materials including one of Q235 steel or Q345 steel.

[0057] In the present invention, Q235 steel has good plasticity and welding properties, and is suitable for manufacturing structural components that bear lighter loads, while Q345 steel has higher strength and wear resistance, and is suitable for components that bear larger mechanical loads. Selecting these two types of steel as the main materials can not only meet the strength and durability required by the steel wheel 1, steel shaft 1 and various steel frame components in the track translation trolley in the tunnel, but also effectively ensure the bearing capacity and long-term stable operation of the entire structure. The use of Q235 or Q345 steel can ensure the stability of the components under high-strength and long-term working conditions, and also has good processing performance, which helps to improve efficiency during production and installation. Choosing one of these two materials can make an appropriate choice based on actual load requirements and cost considerations, thereby providing excellent performance in different working environments.

[0058] Working principle: When in use, the double-row tapered roller bearings can make the steel wheel 1 and the steel shaft 2 rotate with each other, thereby realizing the movement of the rail trolley in the tunnel. When the trolley steel wheel 1 is damaged and needs to be removed and replaced with a new steel wheel 1, first use the hydraulic jack to lift the entire translation trolley to a certain height, then remove the hexagon socket bolts 7 riveted between the steel frame 1 4 and the steel frame 3 3, remove the hexagon socket bolts 7 riveted between the steel frame 2 5 and the steel frame 3 3, remove the damaged steel shaft 2 and steel wheel 1 again, replace the new steel shaft 2 and wheel hub steel wheel 1, finally tighten the hexagon socket bolts 7 riveted between the steel frame 1 4 and the steel frame 3 3, tighten the hexagon socket bolts 7 riveted between the steel frame 2 5 and the steel frame 3 3, and remove the hydraulic jack. Then the steel wheel 1 can be quickly loaded and unloaded.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
