[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0018] Example like Figures 1-5 As shown, this embodiment provides a track for an inspection robot applied to a space frame, including: The track body 1 includes a mounting groove 11, a connecting frame 12, and a track beam 13. The connecting frame 12 is located between the mounting groove 11 and the track beam 13 and connects the mounting groove 11 and the track beam 13 together. The connecting component 2 includes a track connector 21, a vertical hanger 22, and a hanger connector 23. The track connector 21 is inserted into the mounting slots 11 of the two track bodies 1. The track connector 21 is connected to the two mounting slots 11 by bolts. The vertical hanger 22 is located on the side of the track connector 21 away from the track body 1. The hanger connector 23 is connected to the vertical hanger 22 and the track connector 21 respectively, thereby connecting the two together.

[0019] The working process and principle of the above structure are as follows: The track connector 21 and the mounting slot 11 are used to connect two adjacent track bodies 1. The vertical hanger 22 is connected to the track connector 21 through the hanger connector 23, so as to achieve stable aerial fixation of the track body 1. The track beam 13 and the connecting frame 12 bear the displacement of the inspection robot. The non-integrated structure of the connecting component 2 is used to compensate for the internal stress of the structure caused by thermal expansion or construction errors, so as to avoid the deviation or decrease in accuracy of the track system during long-term operation and ensure that the deformation of the structure is controlled under temperature difference. Through the setting of the mounting slot 11, the connecting frame 12 and the track beam 13, the upper and lower structures of the track body 1 have excellent torsional stiffness and redundant bearing capacity. The overall structure meets the high strength requirements while achieving lightweight design, adapting to the requirements of high-altitude erection and long-distance deployment, and significantly reducing the additional load on the main structure.

[0020] In another embodiment of this utility model, such as Figure 1 As shown, the cross-section of the connecting frame 12 is X-shaped.

[0021] The X-shaped connecting frame is more lightweight and forms a hollow space in the middle. The upper and lower structures have excellent torsional stiffness and redundant load-bearing capacity, which significantly reduces the load on the main structure.

[0022] In another embodiment of this utility model, such as Figure 1 and Figure 5 As shown, the cross-section of the track beam 13 is straight. An auxiliary connecting groove 131 is provided on the middle of the side of the track beam 13 away from the connecting frame 12 along the length of the track beam 13. The auxiliary connecting grooves 131 between two connected track bodies 1 are joined together. A connecting strip 132 is connected between two adjacent auxiliary connecting grooves 131. Each connecting strip 132 is provided with at least two countersunk holes 133 at the corresponding two auxiliary connecting grooves 131 and is connected by bolts passing through the countersunk holes 133.

[0023] The auxiliary connecting groove 131 is designed to facilitate the connection of the lower parts of the two track beams 13 together with the connecting strip 132, and then assists in connecting the two track bodies 1 together with the track connector 21, making the connection more secure. The countersunk hole 133 is designed to hide the end of the bolt and avoid affecting the displacement of the inspection robot.

[0024] In another embodiment of this utility model, such as Figures 1-3 As shown, the track connector 21 includes a groove 211, a first connecting plate 212, and a second connecting plate 213. The first connecting plate 212 and the second connecting plate 213 are respectively connected to the edge of the groove 211 in the width direction. The outer width of the groove 211 matches the inner width of the mounting groove 11. The first connecting plate 212 and the second connecting plate 213 are respectively provided with a first sliding hole 214 and a second sliding hole 215. The length direction of the first sliding hole 214 on the first connecting plate 212 and the length direction of the second sliding hole 215 on the second connecting plate 213 are perpendicular to each other. The hanger connector 23 is connected to the first sliding hole 214 on the first connecting plate 212 and the second sliding hole 215 on the second connecting plate 213 by bolts. At least four bolt holes 216 are respectively provided on the two groove walls of the groove 211. The four bolt holes 216 are paired up and correspond to the two mounting grooves 11 respectively, and are connected by bolts passing through the bolt holes 216.

[0025] The groove 211 of the track connector 21 is mainly used to mate with the mounting groove 11. The first connecting plate 212 and the second connecting plate 213 are mainly used to connect with the hanger connector 23. The first sliding hole 214 and the second sliding hole 215 form an expansion joint or flexible connection structure through gap displacement, which compensates for the internal stress of the structure caused by thermal expansion or construction errors, avoids the deviation or decrease in accuracy of the track system during long-term operation, and ensures that the deformation of the structure is controlled under temperature difference changes. The length direction of the first sliding hole 214 and the second sliding hole 215 is set perpendicularly to facilitate adaptation to internal stress deformation in different directions. The four bolt holes 216 on the groove 211 are paired up and respectively connect to the two mounting grooves 11 to realize the connection between the two mounting grooves 11, that is, to connect the two track bodies 1 together.

[0026] In another embodiment of this utility model, such as Figure 1 and Figure 2 As shown, there are two rod connectors 23. The rod connectors 23 are angle steel structures. The two rod connectors 23 are located on both sides of the vertical rod 22. The two rod connectors 23 are respectively connected to the first connecting plate 212 and the second connecting plate 213 by bolts passing through the first sliding hole 214 and the second sliding hole 215.

[0027] The first connecting plate 212 and the second connecting plate 213 are connected by two connecting rods 23 respectively, and then connected to the vertical connecting rod 22 to realize the hoisting and fixing of the track body 1 by the vertical connecting rod 22.

[0028] In another embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a reinforcing rib plate 24 is provided at the included angle of the rod connector 23.

[0029] The addition of the reinforcing rib 24 improves the strength of the hanger connector 23. The welding of the hanger connector 23 to the reinforcing rib 24 ensures the connection and fixation performance of the hanger connector 23 to the vertical hanger 22 and the track connector 21.

[0030] In another embodiment of this utility model, such as Figure 1 As shown, a number of limiting strips 134 are provided on the upper surface of the track beam 13 along its length direction, and the limiting strips 134 are provided on both sides of the connecting frame 12.

[0031] The setting of limit bar 134 effectively prevents the robot from derailing during operation.

[0032] In another embodiment of this utility model, such as Figure 5 As shown, a mounting groove 135 is provided on the lower surface of the track beam 13, and a Hall magnetic array 136 is provided in the mounting groove 135. The mounting groove 135 is arranged along the length direction of the track beam 13.

[0033] The bottom of the track beam 13 has a pre-set mounting slot 135 for installing the Hall magnetic array 136 to ensure that the magnet is firmly installed and improve the stability of the positioning system.

[0034] In another embodiment of this utility model, such as Figure 6 As shown, the inspection route formed by the combination and arrangement of multiple track bodies 1 adopts a U-shaped turnaround track layout.

[0035] Seamless connection of inspection tracks is achieved through a continuous U-shaped zigzag track path, effectively reducing the risk of track interruption and enabling bidirectional phase synchronization control. This ensures complementary distribution of inspection areas on the outbound and return journeys, effectively reducing path overlap. While reducing the number of robots required, it significantly improves overall inspection efficiency; enhances the coverage efficiency of the track inspection system, reduces ineffective robot operation, and avoids material fatigue and long-term stress accumulation issues caused by thermal expansion and contraction of aluminum alloy tracks.

[0036] In another embodiment of this utility model, such as Figure 2 As shown, a reinforcing plate 14 is provided on the outer side surface of the two opposite side walls of the mounting groove 11 and is connected to the mounting groove 11 and the groove body 211 by bolts.

[0037] The reinforcing plate 14 is a long strip-shaped structure with round holes corresponding to the positions of each bolt hole 216. It is used to improve the overall fixing strength of the mounting groove 11 and also plays an auxiliary role in reinforcing the connection between the two mounting grooves 11. It is connected by multiple combined components to achieve a flexible connection, reduce stress concentration, and ensure that the deformation of the structure is controlled under temperature difference changes.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
