[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1 to 2This utility model provides an embodiment of a sheet metal connection structure for a tracked machine, including a support plate 1 and a mounting belt 6. The support plate 1 serves as the basic load-bearing structure of the device, providing a rigid support platform, replacing the traditional screw installation method, and simplifying the assembly process. Multiple stabilizing components are rotatably connected to the center of the support plate 1. The stabilizing components enhance the stability of the support plate 1 during movement, disperse the lateral forces generated during track movement, and prevent deformation or deviation. The stabilizing components include multiple rotating shafts 2, which serve as the rotation center of the stabilizing components, supporting the rotational movement of stabilizing wheels 3. The external parts of the multiple rotating shafts 2 are rotatably connected to the outside of the support plate 1. This connection method allows the rotating shafts 2 to rotate freely, adapting to dynamic load changes during track movement. Stabilizing wheels 3 are fixedly connected to the outside of the multiple rotating shafts 2. The stabilizing wheels 3 support the support plate 1 through rolling contact, reducing motion friction and enhancing smooth operation. The external parts of the multiple stabilizing wheels 3 are in contact with the outside of the support plate 1. The contact structure forms a multi-point support system, evenly distributing the weight of the support plate 1 and avoiding fatigue from single-point stress. Both sides of the support plate 1 are equipped with drive components to provide power to the device. The function of the drive components is to provide power input to the entire connection structure, converting external power into linear motion of the mounting belt 6. A spur gear 5 is fixedly connected to the outside of the drive components. The spur gear 5 serves as the core component for power transmission, meshing with teeth 7 to achieve high torque transmission and ensure stable drive of the mounting belt 6. The drive components include two power shafts 4. The function of the power shafts 4 is to transmit the torque from the external power source to the spur gear 5, adapting to power transmission under harsh working conditions. The two power shafts 4 are rotatably connected to the left and right sides of the support plate 1, respectively. The rotatable connection allows the power shafts 4 to rotate freely, and the coaxiality of the power transmission is ensured by bearing seats.
[0035] The central part of the spur gear 5 is rotatably connected to the outside of the power shaft 4. This connection method rigidly fixes the spur gear 5 to the power shaft 4, ensuring reliable power transmission. The outside of the spur gear 5 contacts the outside of the support plate 1. The contact structure forms a support reference for gear meshing, ensuring correct meshing between the spur gear 5 and the teeth 7. The mounting belt 6 serves as the connecting carrier for the track, and the teeth 7 on it cooperate with the spur gear 5 to achieve motion transmission. The outside of the mounting belt 6 is equipped with anti-slip components. The anti-slip components enhance the friction between the mounting belt 6 and the ground, preventing slippage and improving the traction performance of the equipment. The anti-slip components include multiple anti-slip layers 8. The anti-slip layers 8 directly contact the ground, and their surface texture design increases the coefficient of friction to ensure anti-slip performance. Multiple anti-slip layers 8 are all located on the outside of the mounting belt 6, and their distributed arrangement forms a continuous anti-slip contact strip, covering the entire ground contact area and adapting to different load conditions. The anti-slip layer 8 is made of rubber. The rubber material's high elasticity and wear resistance enhance adhesion to the ground while absorbing some vibration energy. The mounting belt 6 has multiple teeth 7 internally fixed connections. These teeth 7 mesh with the spur gear 5 to transmit power, and their spur tooth design ensures wear resistance during high-frequency meshing. The spur gear 5 and the teeth 7 are meshing, converting the rotational motion of the spur gear 5 into the linear motion of the mounting belt 6, achieving efficient transmission.
[0036] Reference Figures 1 to 6 The support plate 1 has an internal cavity 9, which provides installation space for the energy-absorbing buffer structure, facilitating the installation and maintenance of the dampers 10 and springs 11. Multiple dampers 10 are fixedly connected to the inner wall of the cavity 9. The dampers 10 absorb the impact energy generated during track movement, reducing structural vibration. Springs 11 are fitted around the exterior of each damper 10, providing elastic restoring force and working with the dampers 10 to form a buffer system, optimizing the buffering effect. A sliding plate 12 is slidably connected inside the cavity 9, transmitting external pressure to the dampers 10 and springs 11, ensuring smooth and leak-free sliding. The inner wall of the sliding plate 12 is fixedly connected to the other end of the damper 10, ensuring that the damper 10 effectively absorbs impact energy under pressure. One end of the spring 11 is fixedly connected to one side of the inner wall of the cavity 9, anchoring the spring 11 to the structure of the cavity 9 and ensuring stable deformation. The other end of the spring 11 is fixedly connected to the outside of the sliding plate 12. The purpose of this fixed connection is to transmit the elastic force of the spring 11 to the sliding plate 12, achieving a double buffering effect. A force-bearing plate 13 is fixedly connected to the outside of the sliding plate 12. The force-bearing plate 13 directly bears the pressure transmitted by the mounting belt 6, ensuring no deformation under high loads. The outside of the force-bearing plate 13 is in contact with the inner wall of the mounting belt 6. The purpose of this contact structure is to transmit the pressure of the mounting belt 6 to the force-bearing plate 13, avoiding localized stress concentration.
[0037] Working Principle: The support plate 1 is hoisted to the preset position on the tracked vehicle chassis, and the positioning structure aligns it with the vehicle body to ensure the support surface is level. The stabilizing wheel 3 is pre-installed on the rotating shaft 2. After low-friction rotation via bearings, the stabilizing component is snapped into the mounting groove in the middle of the support plate 1, ensuring that the stabilizing wheel 3 is in close contact with the outer surface of the support plate 1. The power shaft 4 is connected to an external power source via a coupling. After startup, it drives the sprocket 5 to rotate and form initial meshing with the teeth 7 in the mounting belt 6, with the tooth backlash controlled within a reasonable range. The mounting belt 6 is manually pushed onto the outside of the support plate 1 to complete the meshing of the teeth 7 with the sprocket 5. The tensioning mechanism on both sides of the support plate 1 is adjusted to achieve the appropriate tension of the mounting belt 6 to ensure no significant sagging during operation. The anti-slip layer 8 is made of highly elastic wear-resistant material, and its surface texture design enhances the friction with the ground. When the tracked vehicle starts, the anti-slip layer 8 contacts the ground to generate static friction, preventing the mounting belt 6 from spinning and slipping. When the mounting belt 6 is driven forward, the anti-slip layer 8 transmits the ground reaction force to the mounting belt 6. The meshing of the teeth 7 and the spur gear 5 transmits torque to the drive shaft 4. At the same time, the stabilizing wheel 3 rolls on the outer surface of the support plate 1, distributing the weight of the entire machine into multiple support points. When the mounting belt 6 passes over an obstacle, the anti-slip layer 8 is compressed and deformed, transmitting the impact force to the force plate 13 through the mounting belt 6. The force plate 13 pushes the sliding plate 12 to compress the damper 10 and the spring 11, converting the impact energy into heat energy and elastic potential energy. When the sliding plate 12 reciprocates within the cavity 9, the damper 10 continuously provides resistance, controlling the vibration frequency within a safe range.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
