[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0033] See Figures 1 to 4 This utility model discloses a movable base structure suitable for a traction machine, including a fixed base 1, a first translation base 2, a first commutator 3, a universal joint 4, a drive shaft 5, a drive motor 6, a second commutator 7, a second translation base 8, a linear guide rail 9, a ball screw 10, and a crossbeam 11.

[0034] Two fixed bases 1 are respectively arranged on the left and right sides of the equipment, and linear guide rail structures 9 are installed on them. The first translation base 2 and the second translation base 8 can move along the linear guide rail structure 9 to ensure the accuracy and stability of forward and backward movement. The connecting beam 11 connects the first translation base 2 and the second translation base 8 into a whole to ensure the rigidity and stability of the equipment during movement.

[0035] The translation drive is provided by the drive motor 6 located in the middle of the equipment. The power is split into two by the second commutator 7 and transmitted to both sides. It is then transmitted to the universal joint 4 via two drive shafts 5. The universal joint 4 can adapt to the coaxiality deviation of the equipment, which is convenient for on-site installation. The first commutator 3 is connected to the universal joint 4 and transmits the power to the ball screw 10. The ball screw 10 drives the first translation base 2 and the second translation base 8 to move back and forth.

[0036] More specifically, two fixed bases 1 are respectively arranged on the left and right sides of the equipment; each fixed base 1 is provided with a set of linear guide rail structures 9, the extension directions of the two sets of linear guide rails are parallel to each other, the linear guide rail structure 9 includes a first guide rail and a second guide rail that are parallel to each other, and the translation base slides with the first guide rail and the second guide rail.

[0037] Two translation bases are provided, including a first translation base 2 and a second translation base 8. Each translation base is correspondingly provided with a set of linear guide rail structures 9, and the two translation bases are fixedly connected by a crossbeam.

[0038] The moving mechanism is connected between the linear guide structure 9 and the translation base; the moving mechanism includes a ball screw 10, which is connected between the linear guide structure 9 and the translation base. The drive motor 6 is mounted on the crossbeam 11, and the transmission assembly is connected between the drive motor 6 and the ball screw 10. The drive motor 6 drives the ball screw 10 through the transmission assembly, thereby causing the two translation bases to move relative to the two sets of linear guide structures 9.

[0039] Furthermore, the transmission assembly includes a first commutator 3, a second commutator 7, a drive shaft 5, and two universal joints 4; each translation base is provided with one first commutator 3 and one universal joint 4, and the universal joint 4, the first commutator 3, and the ball screw 10 are sequentially connected; the drive motor 6 is a servo motor, located at the center between the first translation base 2 and the second translation base 8, and is connected to the second commutator 7; two drive shafts 5 are provided, and the two drive shafts 5 are of equal length.

[0040] One end of each of the two drive shafts 5 is connected to the second commutator 7, and the other end of each of the two drive shafts 5 extends to the side where the first translation base 2 and the second translation base 8 are located. The other end of each of the two drive shafts 5 is connected to the two universal joints 4.

[0041] As can be seen, a single motor is used as the power source in this embodiment; the servo motor is reduced in speed by a reducer and then the power is transmitted to both sides by a commutator; the power is transmitted to the left and right sides by couplings, drive shafts, and bearing seats on both sides of the commutator; to accommodate the axial dimensions, universal joints are used on both sides to transmit the power to the commutator; the translation bases on both sides are driven by ball screws to ensure synchronization; the translation bases on both sides are each supported by two linear guides to ensure translation accuracy and stability; the translation bases on both sides are connected by a crossbeam to ensure the rigidity and stability of the overall structure.

[0042] The translation bases are arranged on both sides of the equipment, and linear guides are installed on them to ensure translation accuracy and stability. The connecting beams firmly connect the translation bases to ensure the overall rigidity of the equipment. The translation driving force is provided by the motor arranged in the middle, and the power is distributed to the left and right sides by the commutator. Universal joints are set on both sides to accommodate the coaxiality deviation of the equipment and facilitate on-site installation. The universal joints are connected to the commutator to transmit power to the ball screws and ensure that the screws on both sides rotate in the same direction. The movement of the translation bases on both sides is achieved by the internal ball screws to ensure synchronization.

[0043] Therefore, this structure is suitable for the forward and backward translational motion of long-span traction machines, solving not only the problem of translational stability of long-span structures, but also the problem of translational synchronization of long-span structures.

[0044] In summary, the movable base structure for traction machines provided by this utility model can flexibly adjust the distance to the main functional equipment in front and behind according to the process conditions in the actual production line, thereby improving the adaptability of the equipment. The design of connecting the crossbeam and the translation base solves the translation stability problem of long span structures. The single motor provides power, which is distributed by the commutator and driven simultaneously by the ball screws on both sides, thus solving the translation synchronization problem of long span structures.

[0045] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
