The sliding frame 104 is horizontally slidably assembled on the lifting frame 103. One end of the sliding frame 104 is elastically inserted with a side pressure wheel 105, and the side pressure wheel 105 is arranged towards the tunnel wall surface.

[0030] In actual application of this embodiment, a plurality of side rollers 102 are rotatably arranged on the bottom plate 101 along the xoy plane. The side rollers 102 and the side pressure wheels 105 both roll along the wall surface of the tunnel. The lifting frame 103 is longitudinally slidably assembled on the bottom plate 101 along the third direction z, so that the position of the sliding frame 104 can be adjusted according to the curvature of the tunnel side wall, and the elastically inserted side pressure wheel 105 in the sliding frame 104 rolls and abuts against the tunnel side wall, so that the two base modules can move closely along the tunnel wall during the movement process.

[0031] Please refer to Figure 5 , in a preferred embodiment of the present invention, the telescopic assembly 2 includes telescopic beam frames 201, upper lifting frames 202, lateral grooves 203, lower lifting frames 204, guide rods 205, brackets 206, and linkage arms 207. The two telescopic beam frames 201 are respectively fixedly assembled on the two sliding frames 104.

[0032] In actual application of this embodiment, the two groups of telescopic beams 201 are respectively fixedly assembled on the two groups of sliding frames 104, and the telescopic beams 201 are fixedly assembled with an upper lifting frame 202, and lateral grooves 203 are provided on both sides of the lateral grooves 203. Several bottom support plates 401 are limitedly slidably assembled in the lateral grooves 203, and a lower lifting frame 204 is provided at the bottom of the lateral grooves 203. The lower lifting frame 204 is slidably arranged on the top of the transmission box 301 along the third direction z, and a guide rod 205 is further provided on the lower lifting frame 204 along the first direction x, and several brackets 206 are slidably arranged on the guide rod 205, and two groups of linkage arms 207 are also rotatably assembled on the bracket 206, and the two groups of linkage arms 207 are respectively The two sets of bottom support plates 401 on the adjacent sides are rotatably connected, and the bracket 206 located in the middle position is locked in the middle of the guide rod 205 along the third direction z. When the distance between the upper lifting frame 202 and the lower lifting frame 204 changes, since the bracket 206 at the middle position of the guide rod 205 is in a locked state, the multiple brackets 206 on both sides can slide in the first direction x, and the brackets 206 on both sides move in opposite directions, so that when the distance between the upper lifting frame 202 and the lower lifting frame 204 changes, the distance between the multiple brackets 206 changes synchronously, so that the bottom support plates 401 assembled between the multiple brackets 206 can adjust their distance synchronously, and thus the distance between the multiple detection modules changes synchronously.

[0033] Furthermore, the bracket assembly 1 also includes an inclined pressure wheel 106, an electric telescopic rod 107 and a locking plate 108. The inclined pressure wheel 106 is fixedly arranged on one side of the telescopic beam 201, and the inclined pressure wheel 106 is arranged toward the tunnel wall. The electric telescopic rod 107 is fixedly assembled on one end of the telescopic beam 201. The locking plate 108 is fixedly assembled on the movable axis of the electric telescopic rod 107.

[0035] In actual application of this embodiment, when the two telescopic beam frames 201 move away from each other, the first driving inclined surface 208 on the telescopic beam frame 201 slides and abuts against the first driven inclined surface 209. Since the first driven inclined surface 209 is disposed at the bottom of the lower lifting frame 204, the lower lifting frame 204 is driven to move in the third direction z at a speed a. At the same time, the second driving inclined surface 210 synchronously abuts against the second driven inclined surface 211, so that the upper lifting frame 202 moves in the third direction z at a speed b, and the value of the speed b is less than the value of the speed a, so that during the lifting process of the upper lifting frame 202, several detection modules thereon move towards the tunnel top wall direction, and at the same time the distance between the upper lifting frame 202 and the lower lifting frame 204 changes, thereby synchronously changing the distance between several brackets 206, so as to adjust the distribution positions of several detection modules on the tunnel top wall side.
