[0032] See also Figure 3 In order to reduce labor intensity, the moving mechanism 2 in this embodiment includes a mounting block 21, a driving member 22 and a universal wheel 23. The mounting block 21 is fixed to the bottom of the outer surface of the culvert body 1, the driving member 22 is arranged on the lower side of the mounting block 21, and the universal wheel 23 is arranged on the lower surface of the driving member 22.

[0033] The driving member 22 includes a connecting block 221, a bidirectional screw 222, two screw sleeves 223, two movable plates 224 and two insert blocks 225. The connecting block 221 is arranged on the lower side of the mounting block 21. Both ends of the bidirectional screw 222 are rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the connecting block 221 through bearings. The screw sleeve 223 is threadedly connected to the bidirectional screw 222. The movable plate 224 is fixed on the upper surface of the screw sleeve 223. The upper surface of the movable plate 224 passes through the connecting block 221 and extends to the upper side of the connecting block 221. The connecting block 221 is placed It is placed on the lower surface of the mounting block 21 so that the movable plate 224 enters the inner cavity of the fixed groove, and then the bidirectional screw 222 is rotated. The rotation of the bidirectional screw 222 causes the two screw sleeves 223 threadedly connected on its surface to move in opposite directions. The two plug blocks 225 are fixed on the top of the opposite sides of the two movable plates 224. The movement of the screw sleeve 223 causes the movable plate 224 fixed on its upper surface to drive the plug block 225 to move until the plug block 225 enters the inner cavity of the slot 226, so that the connecting block 221 can be fixed to the mounting block 21. At this time, the culvert body 1 can be moved by the universal wheel 23.

[0034] In addition, a fixing groove is provided on the lower surface of the mounting block 21 , the inner cavity of the fixing groove has a smaller size than that of the connecting block 221 , and slots 226 are provided on opposite sides of the left and right side walls of the inner cavity of the fixing groove, the inner cavity size of the slots 226 being adapted to the size of the insert block 225 .

[0035] In this embodiment, one end of the bidirectional screw 222 passes through the connecting block 221 and extends to the outside of the connecting block 221. The universal wheel 23 is rotatably installed on the lower surface of the connecting block 221. A sliding groove is provided on the inner bottom wall of the connecting block 221. A sliding rod is fixed to the lower surface of the screw sleeve 223. The sliding rod makes horizontal linear motion in the inner cavity of the sliding groove. A limiting strip is fixed on the inner top wall of the fixed groove. The top of the movable plate 224 makes horizontal linear motion in the inner cavity of the limiting strip. When the two screw sleeves 223 move, the sliding rod fixed on their lower surfaces moves in the inner cavity of the sliding groove, which can limit the movement of the screw sleeve 223 and make it move horizontally.

[0036] See also Figure 4 In order to facilitate assembly, the assembly mechanism 3 in this embodiment includes two parallel fixed rods 31, four clamping sleeves 32, four threaded rods 33 and two connecting rods 34. The clamping sleeves 32 are fixed on the outer surface of the fixed rod 31, and the threaded rod 33 is fixed on the opposite side of the clamping sleeves 32 at the upper and lower ends. The outer surfaces of the threaded rods 33 at the upper and lower ends are threadedly connected with the connecting rods 34.

[0037] In this embodiment, a magnet is fixed on the left side of the fixing rod 31, and a slot is opened on the right side of the fixing rod 31. The inner diameter of the slot is matched with the inner diameter of the insertion rod, and an iron block is fixed in the inner cavity of the slot. The threads on the outer surfaces of the threaded rods 33 at the upper and lower ends are in opposite structures, and limiting rings are fixed on the opposite sides of the threaded rods 33 at the upper and lower ends.

[0038] It can be understood that a square frame composed of four fixing rods 31 is formed by two assembly mechanisms 3, and the square frame composed of four fixing rods 31 is placed in the inner cavity of the culvert body 1. At this time, the connecting rod 34 on the opposite side of the two ferrules 32 is rotated. The movement of the connecting rod 34 can make the two threaded rods 33 in its inner cavity move back to back or back, and then the positions of the two threaded rods 33 can be adjusted, so that the distance between the two fixing rods 31 changes, which can be applicable to culvert bodies 1 of various sizes.

[0039] In addition, the magnet on the left side of the fixing rod 31 in the other culvert body 1 is inserted into the inner cavity of the slot and attracted by the iron block so that the fixing rods 31 of the two culvert bodies 1 are connected for assembly.

[0040] The working principle of the above embodiment is:

[0041] (1) When assembling two box culvert bodies 1, first place the connecting block 221 on the lower surface of the mounting block 21 so that the movable plate 224 enters the inner cavity of the fixed groove, and then rotate the bidirectional screw 222. The rotation of the bidirectional screw 222 causes the two screw sleeves 223 threadedly connected on its surface to move in opposite directions. When the two screw sleeves 223 move, the sliding rod fixed on the lower surface of the two screw sleeves moves in the inner cavity of the sliding groove, which can limit the movement of the screw sleeves 223 and make them move horizontally. The movement of the screw sleeves 223 causes the movable plate 224 fixed on the upper surface to drive the plug block 225 to move until the plug block 225 enters the inner cavity of the slot 226, so that the connecting block 221 can be fixed to the mounting block 21. At this time, the box culvert body 1 can be moved by the universal wheel 23.

[0042] (2) Then, a square frame consisting of four fixing rods 31 is placed into the inner cavity of the box culvert body 1. At this time, the connecting rod 34 on the opposite side of the two ferrules 32 is rotated. The movement of the connecting rod 34 can make the two threaded rods 33 in its inner cavity move away from each other or away from each other, and then the positions of the two threaded rods 33 can be adjusted, so that the distance between the two fixing rods 31 changes, which can be suitable for box culvert bodies 1 of various sizes. Then, the magnet on the left side of the fixing rod 31 in the other box culvert body 1 is inserted into the inner cavity of the card slot and attracted by the iron block, so that the fixing rods 31 of the two box culvert bodies 1 are connected, thereby assembling.
