[0031] A circulating track, wherein the circulating track comprises a plurality of groups of linear guide rails 100 and arc guide rails 200, wherein the linear guide rails 100 form two groups of parallel tracks of equal length, and the arc guide rails 200 are connected at both ends of the parallel tracks; the circulating track is arranged around the pier of the viaduct to be tested;

[0032] The measuring assembly 300 includes a roller distance meter 310, an elastic rod 320 and a base 330. The base 330 rolls along the circulating track. One end of the elastic rod 320 is connected to the base 330, and the other end is connected to the roller distance meter 310. The elastic rod 320 holds the roller distance meter 310 against the peripheral side of the viaduct pier.

[0033] The linear guide rail 100 is provided with a sliding groove 110, the base 330 is provided with a front guide wheel 341 and a rear guide wheel 342, the sliding groove 110 is provided with a first roller rail 111 and a second roller rail 112, the front guide wheel 341 and the rear guide wheel 342 move along the first roller rail 111 and the second roller rail 112,

[0034] The end surface of the linear guide 100 is provided with a first connecting plate 120, and the linear guide 100 uses the first connecting plate 120 to achieve connection with other linear guides 100 or arc guides 200. The structure of the arc guide 200 is basically the same as that of the linear guide 100. The arc guide 200 is equivalent to being formed by bending the linear guide 100. The arc guide 200 is provided with a second connecting plate 210; the second connecting plate 210 and the first connecting plate 120 can be connected on site by bolting;

[0035] The plurality of groups of linear guide rails 100 and arc guide rails 200 are assembled to form a circulating track, which helps the measuring assembly 300 to form a running track. The arc guide rails 200 have various specifications of curvature. The linear guide rails 100 and arc guide rails 200 can be freely matched and assembled according to the peripheral shape of the viaduct piers, thereby improving the adaptability to viaduct piers of different structures.

[0036] The elastic structure adopted by the measuring assembly 300 can help the roller distance meter 310 adapt to the change of the distance between the linear guide rail 100 and the peripheral side of the viaduct pier. Therefore, even if the constructed circular track cannot completely match the peripheral side shape structure of the viaduct pier, the distance difference in measurement can be compensated by the deformation of the elastic rod 320.

[0037] As a preferred implementation in this embodiment, the front guide wheel 341 provided on the base 330 is driven by a motor, and the motor is arranged inside the base 330. The front guide wheel 341 will serve as a power wheel to drive the measuring component 300 to move.

[0039] The base 330 is further provided with a first accommodating cavity and a second accommodating cavity, and a partition is provided between the first accommodating cavity and the second accommodating cavity; the first accommodating cavity is located on the side of the base 330 close to the roller rangefinder 310;

[0040] As a preferred implementation in this embodiment, the elastic rod 320 includes a limit plate 321, a spring 322, a telescopic rod body 323 and a front rod body 324. The telescopic rod body 323 and the front rod body 324 are connected by the limit plate 321. The spring 322 is nested on one side of the telescopic rod body 323. The telescopic rod body 323 extends from the first accommodating cavity through the partition to the inside of the second accommodating cavity. The front rod body 324 extends out of the first accommodating cavity from one end of the first accommodating cavity away from the partition. The spring 322 is located between the limit plate 321 and the partition.

[0041] In this embodiment, when one end of the front rod 324 is subjected to force, the limit plate 321 will move toward the side of the partition and apply pressure to the spring 322. When the force on the front rod 324 disappears, the spring 322 will again hold the limit plate 321 against the end surface of the first accommodating cavity away from the partition.

[0042] In a further preferred embodiment of the present invention, the linear guide rail 100 is provided with a mounting assembly 400 and a locking bolt 500; the mounting assembly 400 is provided with a screw hole for assembling the locking bolt 500.

[0043] The installation assembly 400 is a triangular structure. When the circulating track is constructed, the locking bolts 500 are tightened from different sides to allow the installation assemblies 400 on different sides to generate corresponding supporting forces, thereby completing the fixed connection with the peripheral side of the viaduct pier. The installation assembly 400 is mainly used to provide supporting points for the linear guide rail 100. The spacing formed by the installation assembly 400 is used to facilitate the arrangement of the measurement assembly 300. The installation assemblies 400 on different sides respectively apply a holding force to the viaduct pier through the locking bolts 500 to complete the fixing needs.

[0044] During the assembly process, the track is assembled on the ground in advance, and after the track is lifted to a specified height, the locking bolt 500 is used to complete the contact with the outer wall of the viaduct pier. After the above assembly task is completed, the roller distance meter 310 moves around the outer side of the viaduct pier under the traction of the base 330 to analyze and measure the outer periphery of the viaduct pier.

[0045] The roller distance meter 310 is a prior art device, which mainly uses the rolling distance of the roller to obtain the length information of the curved surface; the base 330 can also be loaded with a camera to collect image data around the viaduct pier for later comparison and analysis;
