The slots 65 cooperate with the plug-in blocks 63. Four bolts 66 are provided, and the insert block 63 and the slot 65 are fixed to each other by the bolts 66; when the two fixing blocks 61 of the movable seat 51 are respectively placed into the two fixing slots 62, the movable seat 51 can be moved downward, and the L-shaped end of the fixing block 61 is driven to reach the bottom of the fixing slot 62, so that the movable seat 51 and the sliding block 5 can be initially fixed, and then the fixing frame 64 is placed on the movable seat 51 and moved toward the sliding block 5 until the four insert blocks 63 are respectively entered into the four slots 65, and then four bolts 66 are set, which can not only further strengthen the fixation of the limit frame and the movable seat 51, but also limit the movable seat 51.
[0022] The support plate 14 is provided with a lifting mechanism 7 for driving the sliding block 5 and the movable seat 51 to rise and fall. The lifting mechanism 7 includes a second motor 71 fixedly mounted on the top of the support plate 14. A lifting slot 72 is provided on one side of the support plate 14. The sliding block 5 is slidably connected to the inside of the lifting slot 72. The output shaft of the second motor 71 passes through the top of the support plate 14 and a lifting rod 73 is fixed on the output shaft. The bottom end of the lifting rod 73 is rotatably connected to the bottom end of the lifting slot 72 and the outer wall is provided with an external thread. The lifting rod 73 is threadedly connected to the sliding block 5; the lifting rod 73 can be driven to rotate by starting the second motor 71. Since the lifting rod 73 is threadedly connected to the sliding block 5, when the lifting rod 73 rotates, the sliding block 5 can be driven to slide up and down inside the lifting slot 72, and the sliding of the sliding block 5 can drive the movable seat 51 to move together.
[0023] The top of the movable seat 51 is penetrated by a circular groove 52, and a hollow rod 53 is provided inside the circular groove 52. The hollow rod 53 cooperates with the through groove 17. The movable seat 51 is provided with a clamping mechanism 8 for clamping the hollow rod 53. The clamping mechanism 8 includes two clamping blocks 81 that are symmetrical and both are arranged in an arc shape. A motor 3 82 is fixed on one side of the outer wall of the movable seat 51. The output shaft of the motor 3 82 passes through the outer wall of the movable seat 51 and a rotating rod 83 is fixed on the output shaft. A cavity is opened inside the movable seat 51. The end of the rotating rod 83 away from the motor 3 82 is rotatably connected to the inner wall of the chamber 84 and two worms 85 are fixed on the rotating rod 83. The bottom ends of the two worms 85 are meshed with worm wheels 86. The two worm wheels 86 are fixed with positive thread rods 87. One end of the two positive thread rods 87 is fixed with a reverse thread rod 871. One end of the two positive thread rods 87 and the reverse thread rod 871 is rotatably connected to the inner wall of the chamber 84. The two positive thread rods 87 and the two reverse thread rods 871 are connected to each other. The two clamping blocks 81 are fixed to the two moving blocks 89 respectively; by starting the motor three 82, the rotating rod 83 and the two worm gears 85 can be driven to rotate respectively. When the two worm gears 85 rotate, the two worm gears 86 can be driven to rotate together respectively. The rotation of the two worm gears 86 can drive the two positive threaded rods 87 and the reverse threaded rod 871 to rotate together respectively. Since the spirals of the positive threaded rod 87 and the reverse threaded rod 871 are opposite, when both rotate, the two moving plates 88 can be driven to approach each other respectively. When the two moving plates 88 approach each other, the two moving blocks 89 and the two clamping blocks 81 can be driven to move toward the hollow rod 53 until the two clamping blocks 81 play the role of clamping the hollow rod 53, wherein the hollow rods 53 of different specifications can be clamped by changing the distance between the two clamping blocks 81.
[0024] The grouting pump 15 is respectively connected to a grouting pipe 151 and a grouting pipe 152, and a flange 153 is provided between the grouting pipe 152 and the hollow rod 53. Through the setting of the flange 153, the hollow rod 53 and the grouting pipe 152 can be connected. The grouting pipe 151 and the grouting pipe 152 are both hoses, which can facilitate the grouting pipe 152 to move up and down together during the lifting of the hollow rod 53. A limit plate 154 is fixed to the top of the support plate 14, and a limit plate 154 is passed through one end of the grouting pipe 152. All the mechanisms of the above-mentioned device and the grouting pump 15 are connected to the external power supply through existing electric wires, and the slurry in the grouting pipe 151 is connected to the external cement mortar storage tank; by starting the grouting pump 15, the slurry inside the cement mortar storage tank can pass through the slurry inlet pipe 151 and the grouting pipe 152 respectively, thereby entering the interior of the hollow rod 53.
[0025] When highway personnel detect hollow drums and cracks on the highway foundation and find hollow drums and cracks, they can start the drive motor 21 and drive the rotating shaft 23 to rotate inside the bearing seat 22. When the rotating shaft 23 rotates, it can drive the driving wheel 24 to rotate. When the driving wheel 24 rotates, it can drive the belt 27 and the driven wheel 26 to rotate respectively. The rotation of the driven wheel 26 can drive the drive shaft 25 and the two pulleys 11 to rotate respectively. When the two pulleys 11 rotate forward, not only can the entire device be driven forward, but also the two pulleys 12 can be driven forward. When the drill bit 131 moves to the specified position, the motor 34 can be started to drive the drill bit 131 to rotate, and then the cylinder 31 can be started again. The driving block 32 can slide downward in the slide groove 33 through the extension of its piston rod. When the driving block 32 slides downward, it can drive the motor 34 and the drill bit 131 to slide downward together. Then the rotating drill bit 131 can pass through the drill groove 16, and the drill bit 131 can break the soil and drill into the soil. When the drilling depth reaches the expected measured hollow or crack position, the drill bit 131 can be reset.
[0026] Then repeat the operation of the above-mentioned driving mechanism 2 to move the hollow rod 53 to the broken groove. The lifting rod 73 can be driven to rotate by starting the motor 2 71. Since the lifting rod 73 is threadedly connected to the sliding block 5, when the lifting rod 73 rotates, it can drive the sliding block 5 to slide up and down inside the lifting groove 72. The sliding of the sliding block 5 can drive the moving seat 51 and the hollow rod 53 to move downward together. The hollow rod 53 can pass through the through groove 17 and be inserted into the interior of the above-mentioned groove. When the hollow rod 53 reaches the bottom of the groove, the grouting pump 15 is started, and the slurry inside the cement mortar storage tank can pass through the slurry inlet pipe 151, the grouting pipe 152 and the hollow rod 53 respectively, and finally play a filling role. The whole process is simpler and faster than manually inserting the hollow rod 53, saving time and effort.

It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
