[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a civil engineering road bridge crack survey device through improvement. The technical solution of the utility model is:

[0024] like Figure 1-Figure 5 As shown, a civil engineering road bridge crack survey device includes two carts 1, and a first box body 2 and a second box body 3 are fixedly connected to the two carts 1 respectively. A survey component 4 is commonly arranged inside the first box body 2 and the second box body 3. The survey component 4 includes a rotating shaft 41, a pull rope 43, a fixing ring 47 and a camera 48. The two rotating shafts 41 are rotatably connected to the inside of the first box body 2 and the second box body 3 respectively, and the two pull ropes 43 are respectively wound around the two rotating shafts 41. The fixing ring 47 is fixedly connected to the pull rope 43. The camera 48 is fixedly connected to the fixing ring 47. An adjustment component 5 is arranged on the first box body 2. The pull rope 43 will contact the bridge surface during use. Therefore, the pull rope 43 uses wear-resistant material to avoid wear of the pull rope 43 during use.

[0025] Furthermore, the survey component 4 also includes a baffle 42 and a magnet 44. The four baffles 42 are respectively fixedly connected to the two rotating shafts 41. The two pull ropes 43 are respectively located between the four baffles 42. The two magnets 44 are respectively buried in the ends of the two pull ropes 43. The magnet 44 is made of nepidium magnet material, which can improve the magnetic attraction and make it easier for the two sections of the pull rope 43 to fit together when they are close.

[0026] Furthermore, the surveying assembly 4 further comprises a threaded sleeve 45 and a screw rod 46 . The threaded sleeve 45 and the screw rod 46 are respectively fixedly connected to the ends of the two pull ropes 43 , and the threaded sleeve 45 is matched with the screw rod 46 .

[0027] Furthermore, the surveying component 4 also includes a weight ball 49 , and the weight ball 49 is fixedly connected to the fixing ring 47 .

[0028] Furthermore, the adjusting assembly 5 includes a worm wheel 51, a worm 52 and a rotating rod 53. The rotating rod 53 is rotatably connected to the first box body 2. The worm 52 is fixedly connected to the rotating rod 53. The worm wheel 51 is fixedly connected to the rotating shaft 41 in the first box body 2. The worm wheel 51 is meshed with the worm 52. The rotating rod 53 is mainly used for hand cranking to drive the rotating shaft 41 to rotate and control the retraction and extension of the pull rope 43 on the rotating shaft 41. The self-locking effect of the worm wheel 51 and the worm 52 can also prevent the pull rope 43 from shaking.

[0029] Furthermore, the adjustment component 5 also includes a clockwork spring 54, one end of which is fixedly connected to the inner wall of the second box body 3, and the other end of the clockwork spring 54 is fixedly connected to the rotating shaft 41 in the second box body 3. The clockwork spring 54 has a large number of turns so that the pull rope 43 in the second box body 3 can be pulled out to a longer length.

[0030] The specific working method is as follows: first, push the two carts 1 to the sidewalks on both sides above the bridge, throw the two pull ropes 43 from both sides of the bridge to the bottom of the bridge, and then swing the two pull ropes 43 to make them swing closer. Since magnets 44 are embedded at the ends of the two pull ropes 43, when the ends of the two pull ropes 43 are close, the two magnets 44 will be attracted together, so that the two pull ropes 43 are connected together. At this time, grab the pull rope 43 on the second box 3, rotate the rotating rod 53, and move the first box 2 The pull rope 43 in the second box 3 is extended outward, and the pull rope 43 on the second box 3 is pulled upward until the connection between the two pull ropes 43 is pulled above the bridge. At this time, the screw rod 46 can be screwed into the threaded sleeve 45 to firmly connect the two pull ropes 43 together. Then, the pull rope 43 is thrown under the bridge again, and the rotating rod 53 is rotated to move the two pull ropes 43 together toward the first box 2 until the pull rope 43 on the second box 3 is pulled under the bridge, so that the fixing ring 47 and the camera 48 are located under the bridge. At this time, under the action of the gravity of the counterweight ball 49, the counterweight ball 49 will always be downward, while the camera 48 is facing upward, so that the bottom of the bridge can be photographed to observe whether there are cracks at the bottom of the bridge. At this time, the two carts 1 can be moved synchronously so that the camera 48 can move accordingly to observe different positions of the bottom of the bridge. While the camera 48 moves along the direction of travel of the cart 1, the rotating rod 53 can also be rotated to retract the pull rope 43 into the first box body 2, thereby pulling the pull rope 43 in the second box body 3 toward the first box body 2. At this time, the fixing ring 47 and the camera 48 on the pull rope 43 will also move toward the first box body 2. Therefore, the camera 48 can move longitudinally with the cart 1, and by rotating the rotating rod 53, the camera 48 can be moved horizontally, so that any position at the bottom of the bridge can be surveyed. The elastic force of the clockwork spring 54 will keep the two sections of the pull rope 43 in a relatively tight state at all times, thereby preventing the pull rope 43 and the camera 48 from shaking, and also allowing the camera 48 to be closer to the bottom of the bridge.

Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
