[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] like Figure 1-4 As shown, a track vehicle for a tracked tractor production line includes:

[0026] The support cylinder 1 is cylindrical; and the trolley 18 can support the support cylinder 1.

[0027] A rotating shaft 2 is coaxially disposed inside the support cylinder 1; and multiple bearings 3 are all sleeved on the rotating shaft 2 and fixedly connected to the inner ring of the support cylinder 1, configured to support the rotating shaft 2 and support the rotation of the rotating shaft 2. The bottom end of the rotating shaft 2 is connected to a drive component that can drive its rotation.

[0028] The support plate 5 is horizontally positioned and fixedly connected to the top of the rotating shaft 2; and multiple jacks 12 are detachably connected to the support plate 5.

[0029] Specifically, the support cylinder 1 stands upright on the trolley 18, multiple bearings 3 stably support the rotation of the shaft 2, and the jack 12 on the support plate 5 can lift the tractor. The position of the jack 12 can be easily changed through a detachable connection to adapt to the engine chassis.

[0030] Furthermore, the drive assembly includes: a motor 13, a drive shaft 14, a worm 15, and a worm wheel 16. The motor 13 is fixedly mounted on the trolley 18; the worm 15 is fixedly connected to the output shaft of the motor 13; the end of the drive shaft 14 is fixedly connected to the rotating shaft 2, and the end of the drive shaft 14 away from the rotating shaft 2 is fixedly connected to the worm wheel 16, and the worm wheel 16 meshes with the worm 15.

[0031] Specifically, the motor 13 is installed at the bottom of the trolley 18, and the drive shaft 14 passes through the trolley 18. The motor 13 drives the worm gear 15 to rotate, which in turn drives the worm wheel 16 to rotate through meshing. Then the drive shaft 14 follows the worm wheel 16 to rotate. Next, the drive shaft 14 drives the rotating shaft 2 to rotate, and the rotating shaft 2 synchronously drives the support plate 5 to rotate, causing the tractor to rotate and turn around.

[0032] Furthermore, the output end of the jack 12 is fixedly connected to a connecting plate 20, and a support seat 21 is detachably connected to the connecting plate 20. The support seat 21 can support the tractor chassis, making it easy to install the tractor chassis. The support seat 21 is fixed to the connecting plate 20 by bolts or other fasteners, making it easy to disassemble and replace, and adapting to different models of tractor chassis.

[0033] Furthermore, a reinforcing rib 4 is provided between the outer wall of the support cylinder 1 and the trolley 18 to enhance stability. By reinforcing the four sides of the support cylinder 1 with the reinforcing rib 4, the support cylinder 1 is prevented from tilting, which in turn ensures that the rotating shaft 2 stably supports the support plate 5 and prevents the tractor from tilting.

[0034] Furthermore, the bottom of the trolley 18 is equipped with rollers 19, which enable it to move within the track.

[0035] Furthermore, it also includes: insert post 6, limiting ear 7, and connecting block 8. There are multiple insert posts 6, which are fixedly connected to the surface of the support plate 5. The limiting ear 7 is set on both sides of the top of the insert post 6. The bottom of the connecting block 8 is provided with insertion holes 9 and slots 11 for inserting the insert post 6 and the limiting ear 7. The bottom of the insertion holes 9 and slots 11 is provided with annular limiting grooves 10, which can rotate the connecting block 8 after the insert post 6 and the limiting ear 7 are inserted, so that the connecting block 8 cannot fall off the insert post 6. The jack 12 is fixedly connected to the top of the connecting block 8.

[0036] Specifically, by rotating the connecting block 8 so that the slot 11 corresponds to the limiting ear 7, the connecting block 8 can be removed from the insert 6. By reversing the above steps, the insert 6 can be inserted into the insertion hole 9, and the connecting block 8 can be installed on the insert 6. Continue rotating, and the limiting ear 7 enters the limiting groove 10, which can prevent the connecting block 8 from falling off. Therefore, the position of the jack 12 can be changed to adapt to different models of tractors.

[0037] In the above structure, the trolley 18 is pushed under the tractor, and then multiple jacks 12 are used to lift the tractor. When it needs to move, the tractor can be moved by the support of the trolley 18. When it needs to turn, the roller 19 is pressed to start the motor 13 to drive the worm gear 15 to rotate, which in turn drives the worm wheel 16 to rotate through meshing. Then the drive shaft 14 rotates with the worm wheel 16. Next, the drive shaft 14 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the support plate 5 to rotate, so that the tractor can rotate and turn around. When it is necessary to adjust the position of the jack 12, the connecting block 8 is rotated so that the slot 11 corresponds to the limit ear 7, and the connecting block 8 can be removed from the insert 6. The connecting block 8 can be installed on the insert 6 by reversing the above steps. Therefore, the position of the jack 12 can be changed to adapt to different models of tractors.
