[0040] Please refer to Figures 1-8 An embodiment of this utility model provides a flexible wheel assembly, including a mounting plate assembly 1, a first rotating shaft 2, a wheel assembly 3, a drive assembly 4, and a connecting seat 5, wherein...

[0041] The mounting plate assembly 1 includes an active mounting plate 11 and a driven mounting plate 12 arranged symmetrically;

[0042] The first rotating shaft 2 is fixedly disposed between the active mounting plate 11 and the driven mounting plate 12. The active mounting plate 11 is rotatably connected to one end of the first rotating shaft 2, and the driven mounting plate 12 is rotatably connected to the other end of the first rotating shaft 11. Specifically, the first rotating shaft 2 is located below the wheel assembly 3. The planes on which the active mounting plate 11 and the driven mounting plate 12 are located are perpendicular to the axis of the first rotating shaft 2. One end of the first rotating shaft 2 passes through the active mounting plate 11, and the other end passes through the driven mounting plate 12. Both ends of the first rotating shaft 2 are fixedly provided with shaft end baffles 21 by anti-loosening washers and hexagonal bolts. The first rotating shaft 2 is fixedly sleeved with a shaft ring 22 on the inner side of the active mounting plate 11 and the driven mounting plate 12 to limit the active mounting plate 11 and the driven mounting plate 12 and prevent the active mounting plate 11 and the driven mounting plate 12 from deviating when rotating.

[0043] The wheel assembly 3 includes an active wheel assembly 31 disposed on the active mounting plate 11 and a driven wheel assembly 32 disposed on the driven mounting plate 12. Both the active wheel assembly 31 and the driven wheel assembly 32 are symmetrically arranged about the axis of the first rotating shaft 2.

[0044] The drive assembly 4 is connected to the active wheel assembly 31 and is used to drive the wheel assembly 3 to travel along the guide surface of the track.

[0045] When the wheel assembly 3 passes over an uneven area, both the active mounting plate 11 and the driven mounting plate 12 rotate around the rotatable connection along the longitudinal plane, so that the active wheel assembly 31 and the driven wheel assembly 32 swing up and down along the longitudinal direction around the rotatable connection.

[0046] Specifically, the main beam rail of the gantry crane is set horizontally, the wheel assembly 3 presses on the guide surface of the main beam rail, the first rotating shaft 2 is located below the main beam rail and is fixed by the connecting seat 5. The first rotating shaft 2 does not rotate, and the connecting seat 5 is fixedly connected to the hoisting mechanism.

[0047] In use, the drive assembly 4 drives the active wheel assembly 31 to rotate, thereby causing the wheel assembly 3 to travel along the guide surface of the track. As the wheel assembly 3 travels, it drives the hoisting mechanism to move synchronously, completing the hoisting operation. When the wheel assembly 3 travels to an uneven position, the active mounting plate 11 can rotate around its rotational connection with the first rotating shaft 2 along the longitudinal plane, thereby causing the front and rear parts of the active wheel assembly 31 mounted on the active mounting plate 11 to swing up and down longitudinally around the rotational connection. Similarly, the driven mounting plate 12 can rotate around its rotational connection with the first rotating shaft 2. Rotating along the longitudinal plane, the front and rear parts of the driven wheel set 32 ​​mounted on the driven mounting plate 12 swing up and down longitudinally around the rotation connection. According to the theory that three points determine a plane, when traveling in an uneven position, three sets of wheels in the front and rear parts of the driving wheel set 31 and the driven wheel set 32 ​​are in contact with the guide surface of the track, while only one set of wheels is suspended in the air. This ensures that there are support points on both sides of the wheel assembly 3, avoiding tilting where only one side of the wheel is in contact with the track, and improving the stability of the wheel set operation.

[0048] Preferred, such as Figure 1 and Figure 2 As shown, both ends of the active mounting plate 11 and the driven mounting plate 12 along their length direction are provided with end plates 13. The two end plates 13 located at the same end are symmetrically provided with U-shaped grooves 131 for the track to pass through. The openings of the U-shaped grooves 131 are arranged opposite to each other, and the opening height of the U-shaped grooves 131 is greater than the thickness of the track.

[0049] Specifically, the track passes through the U-shaped groove 131, which limits the two longitudinal sides of the track to prevent the wheel assembly of this application from slipping off the track when traveling along the track; and the opening height of the U-shaped groove 131 is greater than the thickness of the track, and there are gaps between the top and bottom of the track and the inner wall of the U-shaped groove, so that the active hanging plate 11 and the driven hanging plate 12 can rotate around the rotating connection point along the longitudinal plane.

[0050] Preferred, such as Figure 1 and Figure 2 As shown, the connecting seat 5 is located below the first rotating shaft 2 and is used to connect with the hoisting mechanism. The second rotating shaft 6 is fixedly installed on the connecting seat 5 through the clamping plate 7, and the second rotating shaft 6 is fixedly connected to the first rotating shaft 2.

[0051] Specifically, the clamping plate 7 is fixed to the connecting seat 5 by bolts, and a recessed groove is provided on the circumferential surface of the second rotating shaft 6. The clamping plate 7 engages with the recessed groove to keep the second rotating shaft 6 fixed.

[0052] Preferred, such as Figure 1 and Figure 2As shown, the connecting seat 5 includes a base plate and a fixing plate symmetrically arranged on the base plate. The first rotating shaft 2 is arranged between the fixing plates. The second rotating shaft 6 is fixedly connected to the fixing plate and passes through the first rotating shaft 2. The circumferential surface of the first rotating shaft 2 is symmetrically recessed inward to form a recessed plane 22. The recessed plane 22 is in contact with the inner side of the fixing plate.

[0053] Specifically, the recessed plane 22 fits against the inner side of the fixed plate, so that the first rotating shaft 2 is fixed between the two fixed plates, keeping the first rotating shaft 2 fixed and preventing it from rotating; and the bottom plate is provided with mounting holes, through which it is connected to the hoisting mechanism.

[0054] Preferred, such as Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, the active wheel assembly 31 includes two sets of active wheels 311 arranged side by side along the length of the active mounting plate 11. The active wheels 311 are rotatably connected to the active mounting plate 11 through bearings. The driven wheel assembly 32 includes two sets of driven wheels 321 that correspond one-to-one with the active wheels 311 and are arranged coaxially. The driven wheels 321 are rotatably connected to the driven mounting plate 12 through bearings.

[0055] Specifically, the two driving wheels 311 and the two driven wheels 321 have the same structure and size, and are symmetrically arranged about the axis of the first rotating shaft 2, so that the two driving wheels 311 and the two driven wheels 321 can swing up and down longitudinally around the first rotating shaft 2.

[0056] Preferred, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the drive assembly 4 includes a drive motor 41, a drive gear 42, and a driven gear 43. The drive motor 41 is fixedly mounted on the drive mounting plate 11. The drive gear 42 is coaxial with and fixedly connected to the output end of the drive motor 41. The driven gear 43 is correspondingly mounted to the drive wheel 311 and is coaxial with and fixedly connected to the drive wheel 311 by bolts. The drive gear 42 and the driven gear 43 mesh.

[0057] Specifically, two fixed shafts are arranged side by side along the length of the active mounting plate 11. Each fixed shaft is fitted with an active wheel 311 and a driven gear 43. The active wheel 311 is rotatably connected to the fixed shaft through bearings, and the driven gear 43 is fixedly connected to the active wheel 311 through bolts. When the drive motor 41 drives the active gear 42 to rotate, the active gear 42 drives the two driven gears 43 meshing with it to rotate. The rotation of the driven gears 43 in turn drives the two active wheels 311 to rotate synchronously, driving the wheel set to travel along the guide surface of the track. The drive structure is simple and stable.

[0058] Preferred, such asFigure 1 and Figure 2 As shown, a dust cover 8 is provided on the top of the active mounting plate 11. The dust cover 8 is located above the active gear 42 and the driven gear 43 to prevent a large amount of dust from accumulating on the gears and affecting the normal driving operation of the wheel assembly.

[0059] Preferred, such as Figure 1 and Figure 2 As shown, an oil collection tray 9 is provided on the active mounting plate 11 below the drive motor 41. Specifically, the drive motor 41 is prone to oil leakage during operation. The oil collection tray 9 can collect the leaked oil from the drive motor 41, preventing the oil from falling onto the ground.

[0060] Working principle:

[0061] In use, the circumferential surfaces of the two driving wheels 311 and the two driven wheels 321 are pressed against the guide surface of the track. Then, the driving motor 41 drives the driving gear 42 to rotate, and the driven gear 43 drives the two driving wheels 311 to rotate, thereby driving the wheel assembly 3 to travel along the guide surface of the track. When the wheel assembly 3 travels, it drives the hoisting mechanism to travel synchronously to complete the hoisting work.

[0062] When the wheel assembly 3 travels to an uneven position, the active mounting plate 11 can rotate along the longitudinal plane around its rotational connection with the first rotating shaft 2, thereby causing the two active wheels 311 mounted on the active mounting plate 11 to swing up and down along the longitudinal direction around the rotational connection. Similarly, the driven mounting plate 12 can rotate along the longitudinal plane around its rotational connection with the first rotating shaft 2, thereby causing the two driven wheels 321 mounted on the driven mounting plate 12 to swing up and down along the longitudinal direction around the rotational connection. According to the theory that three points determine a plane, at each moment when traveling in an uneven position, three sets of wheels of the two active wheels 311 and the two driven wheels 321 are always in contact with the guide surface of the track, and one set of wheels is suspended in the air. This ensures that there are support points on both sides of the wheel assembly 3, avoiding tilting where only one side of the wheel is in contact with the track, and improving the stability of the wheel assembly operation.
