[0002] Track robots are robots that travel along a set track and are usually used for inspections. They are increasingly used in modern industry. Track robots usually travel along a specific path determined by an I-shaped track and complete tasks such as inspections during the movement. Track robots need to be equipped with a drive device, which cooperates with the I-shaped track to realize the travel drive of the track robot.

[0003] In order to enable the rail robot to move continuously and stably along the I-shaped track, the travel drive device should maintain appropriate contact with the I-shaped track, and during the movement, when the I-shaped track changes in curvature and slope, the travel drive capability can still be guaranteed, and the travel drive effect should be as unaffected as possible by factors such as deformation, depression and protrusion of the I-shaped track, to ensure that the rail robot can move continuously and stably along the I-shaped track. The drive device of the existing rail robot does not have the above characteristics and needs to be developed and designed according to needs. Utility Model Content

[0004] The purpose of the utility model is to provide a driving device for a rail robot, which maintains continuous and reliable contact with the I-rail when the rail robot moves along the I-rail, improves the continuity and reliability of the rail robot's walking drive, and ensures that the walking drive effect is not affected by factors such as deformation, depression and protrusion of the I-rail.

[0011] The advantages and positive effects of the utility model are:

[0012] The utility model provides a driving device of a rail robot with a reasonable structural design. Compared with the existing driving devices applied to rail robots, the walking driving device in the utility model installs the driving shaft seat on the rail block moving along the slide rail and uses a tension spring to provide a pulling force for the driving shaft seat in the length direction of the slide rail, so that the driving wheel installed on the driving shaft seat can maintain a continuous and stable combination relationship with the middle plate of the I-shaped rail, and can provide a continuous and reliable walking driving effect for the rail robot. By setting an adjusting bolt for adjusting the tension of the tension spring, the adjustment setting of the tension of the tension spring is realized. After adjustment, the rim of the driving wheel is pressed on the I-shaped rail with a suitable pressure, further ensuring the continuity and reliability of the walking drive, so that the walking drive effect is not affected by factors such as deformation, depression and protrusion of the I-shaped rail.

[0013] By using a telescopic structure and a key connection to transmit the input shaft of the drive shaft seat and the drive shaft of the transmission assembly, a technical effect is achieved by allowing the drive shaft seat and its drive wheel to move translationally along the slide rail while maintaining transmission.

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0019] See also Figure 1 and Figure 2 The driving device of the rail robot of the utility model includes a slide rail assembly and a track block installed on the slide rail assembly.

A driving wheel 1 is installed on the output shaft of the driving shaft seat 2, and the rim of the driving wheel 1 is pressed on the middle plate of the I-rail.

[0020] As shown in the figure, the driving wheel 1 is located above the driving shaft seat 2. The driving shaft seat 2 includes a shaft seat shell. An input shaft 8 is installed on the side of the shaft seat shell and an output shaft is installed on the top. The driving wheel 1 is installed on the output shaft. Therefore, a transmission mechanism is arranged inside the shaft seat shell. In this embodiment, a bevel gear set is arranged inside the shaft seat shell, and the input shaft 8 and the output shaft are connected by the bevel gear set.

[0021] In this embodiment, the slide rail assembly includes a first slide rail 3 and a second slide rail 14 arranged opposite to each other, a first track block 4 is mounted on the first slide rail 3, a second track block 13 is mounted on the second slide rail 14, and the drive shaft seat 2 is mounted and fixed between the first track block 4 and the second track block 13. As shown in the figure, mounting plates are provided on both sides of the drive shaft seat 2, and the two mounting plates are respectively fixedly connected to the first track block 4 and the second track block 13 by bolts, and the main body of the drive shaft seat 2 is located between the first track block 4 and the second track block 13.

[0022] It also includes a light bar assembly and a slider installed on the light bar assembly. A tension spring is installed between the track block and the slider on this side. The tension spring is used to provide tension to the drive shaft seat 2 in the moving direction, so that the rim of the drive wheel 1 is pressed against the middle plate of the I-shaped track with appropriate pressure. The length direction of the light bar assembly is parallel to the length direction of the slide rail assembly. It also includes an adjustment bolt for adjusting the tension of the tension spring. The tension spring is adjusted by adjusting the bolt to have different tensions and different tensions, thereby realizing the adjustment and setting of the pressure between the drive wheel 1 and the I-shaped track.

[0023] In this embodiment, the optical bar assembly includes a first optical bar 7 and a second optical bar 17 that are arranged opposite to each other. A first slider 6 is installed on the first optical bar 7, and a second slider 16 is installed on the second optical bar 17. As shown in the figure, the first optical bar 7 and the second optical bar 17 have the same structure. A first tension spring 5 is installed between the first track block 4 and the first slider 6, and a second tension spring 15 is installed between the second track block 13 and the second slider 16. Specifically, the front end of the tension spring is fixed to the side of the track block 4 on this side by bolts, and the rear end of the tension spring is fixed to the side of the slider on this side by bolts. The tension of the tension spring is adjusted and set by adjusting the position of the slider on the optical bar.

[0024] A first adjusting bolt 18 for adjusting the tension of the first tension spring 5 is installed on the first optical bar 7, a threaded hole is provided in the middle of the first slider 6 and the first adjusting bolt 18 is located in the threaded hole; a second adjusting bolt 19 for adjusting the tension of the second tension spring 15 is installed on the second optical bar 17, a threaded hole is provided in the middle of the second slider 16 and the second adjusting bolt 19 is located in the threaded hole. When adjusting, a tool is used to combine with the outer ends of the first adjusting bolt 18 and the second adjusting bolt 19 and drive the adjusting bolts to rotate forward or reverse, and accordingly, the slider moves forward or backward.

[0025] Specifically, Figure 1 As shown in , the first optical bar 7 and the second optical bar 17 each include a support located at both ends and two upper and lower cross bars located between the two supports. The first slider 6 and the second slider 16 are each provided with two upper and lower guide holes, and the two cross bars are respectively located in the two guide holes, so that the slider can move axially along the cross bar of the optical bar. The adjusting bolt is a long bolt, and its two ends are respectively mounted on the two supports of the optical bar through bearings, and the middle of the adjusting bolt is located between the two cross bars, and the nut of the adjusting bolt is located at the rear end, so that the adjusting bolt can only rotate in a rotation direction, but cannot move in the axial direction. When the nut of the adjusting bolt is driven to rotate by a tool, the adjusting bolt rotates in a rotation direction, so the adjusting bolt and the slider on this side constitute a "screw-nut" structure, the adjusting bolt is equivalent to the screw, and the slider is equivalent to the nut. When the adjusting bolt as the screw rotates in a rotation direction, the slider as the nut correspondingly moves in a translation direction in the axial direction.

[0026] It also includes a transmission assembly for transmitting the driving action of the driving machine to the drive shaft seat 2. An axial hole is provided at the center of the drive shaft 10 of the transmission assembly. The rear end of the input shaft 8 of the drive shaft seat 2 is located in the axial hole of the drive shaft 10 and is connected by a key. In this way, the input shaft 8 and the drive shaft 10 form a retractable shaft structure. The input shaft 8 can be inserted more into the axial hole on the drive shaft 10, or extended more, and the length of the shaft structure changes accordingly. The aforementioned telescopic input shaft 8 and drive shaft 10 allow the drive shaft seat 2 and its drive wheel 1 to move forward and backward along the length direction of the slide rail on the basis of ensuring the transmission effect.

[0027] In this embodiment, the transmission assembly includes a transmission box 12 and a transmission gear set 11 located in the transmission box 12 , and the rear end of the drive shaft 10 is fixedly connected to the center of the output gear of the transmission gear set 11 .

[0028] In this embodiment, an oil seal end cover 9 is also installed at the front end of the drive shaft 10, an axial hole is provided in the center of the oil seal end cover 9 and the input shaft 8 is located in the axial hole, and oil seal gaskets are also installed between the oil seal end cover 9 and the input shaft 8 and between the oil seal end cover 9 and the drive shaft 10, and lubricating oil is injected into the joint position of the input shaft 8 and the drive shaft 10.
