Detailed Implementation

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] like Figure 1-12As shown, this invention provides a road surface crack detection and repair device for recycled concrete. The components of the device are made of pressure-resistant, corrosion-resistant, and wear-resistant materials. It includes a frame 1, a lifting plate 19 connected to the frame 1 via a lifting mechanism, and a detection mechanism on the lifting plate 19 for detecting road surface cracks. The detection mechanism includes a hollow rod 20 rotatably connected to the lifting plate 19. The hollow rod 20 is hollow inside, and an annular box 61 is fixedly connected to its lower end. An annular rack 66 is rotatably connected inside the annular box 61, meshing with a drive gear 67. The drive gear 67 is fixedly installed on one end of a gear shaft 68, and the other end of the gear shaft 68 is fixedly connected to the power output shaft of a motor 69. The motor 69 is fixedly installed inside the annular box 61. A driven gear 70 is symmetrically meshed with the lower part of the annular rack 66. A detection screw 71 is fixedly installed at the end of the detection screw 71, which is rotatably mounted on the annular box 61. The detection screw 71 extends into the fixed tube 64, which is symmetrically fixed on the annular box 61. The detection screw 71 is threadedly connected to the nut sleeve 83, which is slidably connected to the fixed tube 64. A connecting ring 79 is slidably connected to the end of the nut sleeve 83. A detection frame 81 is fixedly connected to the end of the connecting ring 79 away from the nut sleeve 83. A roller 82 is hinged on the detection frame 81. A pressure sensor 80 is connected between the detection frame 81 and the nut sleeve 83. A detection slide rod 65 is slidably connected inside the hollow rod 20. A connecting rod 62 is fixedly connected to the lower part of the detection slide rod 65. A conical head 63 is fixedly connected to the lower end of the connecting rod 62. A tension sensor 78 is connected to the upper part of the detection slide rod 65, and a rope 77 is connected to the tension sensor 78.

[0045] During operation, the hollow rod 20 moves downwards to be flush with the road surface, and the rope 77 moves downwards, thereby driving the tension sensor 78 downwards, which in turn drives the connecting rod 62 downwards, and thus the conical head 63 downwards to contact the bottom of the crack. After contact, the tension sensor 78 senses the change in tension. By measuring the release length of the rope 77 when the tension sensor 78 senses the change in tension, the depth of the crack is calculated. When detecting the crack width, the hollow rod 20 moves downwards, thereby driving the annular box 61 downwards into the crack. The motor 69 is then activated, driving the gear shaft 68 to rotate, which in turn drives the drive gear 67 to rotate. The drive gear 67 meshes with the annular rack 66, thereby driving the annular rack 66 to rotate. The detection screw 71 rotates by meshing with the driven gear 70. The detection screw 71 is threadedly connected to the nut cylinder 83, which in turn moves the nut cylinder 83, thereby moving the connecting ring 79, which in turn moves the detection frame 81, which in turn moves the roller 82 to contact the edge of the crack. Upon contact, the roller pushes the detection frame 81 to move, which in turn moves the connecting ring 79, thereby squeezing the pressure sensor 80. When the pressure sensor 80 senses the pressure change, it calculates the width of the crack by the distance between the two rollers 82. The hollow rod 20 rotates, which in turn moves the annular box 61, which in turn moves the fixed tube 64, which in turn moves the roller 82. The crack width is measured by the pressure change of the pressure sensor 80.
