[0030] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0031] Example 1: like Figures 1-5 As shown, this is a preferred embodiment of the present invention, a heavy-duty laterally movable ball wheel, including a spherical wheel 1, a support wheel set 2, a power wheel set 3, a rotary motor 4, a lifting component and a traveling bracket 6; The walking support 6 is divided into a bottom compartment 61, a middle compartment 62 and an upper compartment 63 from bottom to top; the support wheel group 2 is provided on the inner wall of the bottom compartment 61, and the spherical wheel 1 is provided in the bottom compartment 61 and abuts against the support wheel group 2; the support wheel group 2 is evenly arranged in several groups around the axial direction of the walking support 6 and along the circumference of the bottom compartment 61. The power wheel set 3 is connected to the rotary motor 4 and is located in the middle compartment 62. The rotation of the power wheel set 3 is controlled by the rotary motor 4. The lifting assembly is installed inside the upper compartment 63. The output end of the lifting assembly is connected to the rotary motor 4. The lifting assembly controls the power wheel set 3 to contact or separate from the spherical wheel 1.

[0032] This invention controls the steering of the power wheel set 3 by rotating the motor 4, thereby controlling the walking direction of the spherical wheel 1, thus achieving zero-radius turning and flexible operation to adapt to various terrains.

[0033] The support wheel assembly 2 includes a roller, a support column 21, a roller shaft 22, a sliding block 23, and a spring 24; the support column 21 is provided on both sides of the roller, and a support wheel assembly base 64 is provided in the bottom compartment. The support column 21 is connected to the support wheel assembly base 64. The support column 21 is provided with a sliding groove, and the sliding block 23 is provided in the sliding groove; the roller shaft 22 is provided in the roller, and both ends of the roller shaft 22 are respectively connected to the sliding block 23. One end of the spring 24 is connected to the inner wall of the groove near the support wheel base 64, and the other end is connected to the sliding block 23.

[0034] The roller is preferably a spindle-shaped cylindrical roller. By setting a spring 24, the roller can slide along the groove and can maintain rolling even when the direction of movement of the spherical wheel 1 is not perpendicular to the roller shaft 22.

[0035] The power wheel set 3 includes a rubber wheel 32 and a power base 31. The rubber wheel 32 is connected to the bottom of the power base 31 by a bearing.

[0036] The power wheel set 3 uses a high-friction rubber wheel set to transmit power to the spherical wheel 1. The rubber wheel 32 is drum-shaped and tangent to the spherical wheel 1 to increase the contact area. Every two rubber wheels 32 form a power wheel set 3. In some embodiments, the power base 31 may also be equipped with a drive motor connected to the rubber wheels 32 as a forward power source.

[0037] The rubber wheel 32 is in the shape of a waist drum, and the surface of the rubber wheel 32 is provided with anti-slip patterns.

[0038] The rotary motor 4 is located on the top of the power base 31. The rotary motor 4 is connected to the lifting assembly. Multiple metal blocks 41 are arranged on the outer wall of the rotary motor 4 along the circumference of the rotary motor 4.

[0039] The direction of the drive wheel set 3 is adjusted by rotating the motor 4. The metal block 41 outside the rotating motor 4 is used as the base when the car platform is lifted.

[0040] The middle compartment 62 is provided with a support ring 65, the rotary motor 4 passes through the support ring 64 and is connected to the lifting assembly, and the support ring 64 is provided with a notch 66 to facilitate the passage of the metal block 41.

[0041] The lifting assembly uses a hydraulic cylinder 5. The piston rod of the hydraulic cylinder 5 is connected to the rotary motor 4, and the cylinder barrel of the hydraulic cylinder 5 extends out of the upper compartment 63 and is connected to external equipment.

[0042] The main purpose of this structure is to prevent the power wheel set 3 from being used as the support base for the hydraulic cylinder, which would cause damage. When the heavy-duty, laterally movable ball wheel supports a heavy object, the metal block 41 on the rotary motor 4 can be made to pass through the notch 66 on the support ring 65 by retracting the hydraulic cylinder 5. Then, the rotary motor 4 rotates synchronously, causing the metal shell 41 on its outer wall to be misaligned with the notch 66 and supported on the support ring 65.

[0043] The spherical wheel 100 has a lightweight alloy interior and a rigid polyurethane rubber coating on its outer surface. The lightweight alloy is not easily deformed; the rigid polyurethane rubber coating on the outer surface gives the spherical wheel 100 high strength, high friction, and low elasticity.

[0044] Example 2 Combination Figure 6 As shown, a heavy-duty, laterally movable pipe transport vehicle adopts the aforementioned heavy-duty, laterally movable ball wheels and also includes a vehicle platform 200; the heavy-duty, laterally movable ball wheels 100 are respectively provided at the four bottom corners of the vehicle platform 200, and the ball wheels 100 are connected to the vehicle platform 200 through the cylinder of the hydraulic cylinder 5. The top of the flatbed 200 is also provided with detachable wing plates 300 on both sides, and the wing plates 300 are arranged in a U-shape.

[0045] The flatbed 200 serves as the main part for transporting pipe sections. Removable wing plates 300 are installed on both sides to prevent the round pipe from shaking and rolling off. The four corners below the flatbed 200 are connected to the cylinders of the hydraulic cylinders 5, and transportation is achieved through ball wheels 100.

[0046] The transport vehicle is equipped with ultrasonic transmitting and receiving devices on both the front and rear sides.

[0047] When transporting extra-long pipes, multiple pallet trucks can be used in conjunction. Ultrasonic transmitting and receiving devices are installed on the front and rear side panels of the pipe transport pallet trucks to precisely control distance and axis alignment, preventing the pipes from slipping and bending due to misalignment of the transport pallet trucks.

[0048] The specific operation and management process of this implementation is as follows: Before transporting the pipeline, the pipeline is placed on concrete piers on both sides. The spherical flatbed truck lowers its height using hydraulic cylinder 5, so that the highest point of the wing plate 300 on the flatbed truck surface 200 is lower than the lowest point of the pipeline. The flatbed truck moves forward to directly under the pipeline, and the hydraulic cylinder 5 restores the height, so that the pipeline is on the flatbed truck.

[0049] During operation, the hydraulic cylinder 5 is lifted, and under the pressure of the upper flatbed 200, the power wheel set 3 is pressed against the spherical wheel 1, so that the spherical wheel 1 moves along the rotation direction of the power wheel set 3; when braking is required, the power wheel set 3 is adjusted to the opposite direction.

[0050] When turning, the hydraulic cylinder 5 retracts, the power wheel set 3 separates from the spherical wheel 1, the rotary motor 4 above the power wheel set 3 rotates to the required angle, the hydraulic cylinder 5 rises again, the power wheel set 3 contacts the spherical wheel 1, and the spherical wheel 100 moves forward in the new direction.

[0051] When the pipeline is placed, the hydraulic cylinder 5 retracts, and the rotary motor 4 rotates simultaneously until the metal block 41 on the outside of the rotary motor 4 passes through the reserved notch 66; the rotary motor 4 rotates again, the hydraulic cylinder 5 extends, and the metal block 41 falls onto the support ring 65, placing the pipeline onto the concrete pier of the new site. This avoids the problem of the power wheel set 3 being easily damaged when used as the support foundation for the hydraulic cylinder.

[0052] After placement, reverse the steps described above to remove the pallet truck from the bottom of the pipeline, thus completing the pipeline transport.

[0053] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
