Block 9, the bottom ends of the front-to-back symmetrical telescopic rods 7 are commonly fixedly connected with a mounting plate 10, the two mounting plates 10 are slidably connected with symmetrically arranged connecting rods 12, the side ends of the front-to-back symmetrical connecting rods 12 are commonly fixedly connected with baffles 13, the side walls of the two baffles 13 are fixedly connected with first springs 14, the other side ends of the plurality of connecting rods 12 are fixedly connected with connecting frames 15, the plurality of connecting frames 15 are rotatably connected with stabilizing wheels 16, the plurality of moving rods 5 are fixedly connected with first support rods 17, and the plurality of first support rods 17 are rotatably connected with first pulling rods 18; The mounting frame 1 is provided with symmetrically arranged mounting grooves 19, and square blocks 20 are slidably connected inside the two mounting grooves 19, and the two square blocks 20 are fixedly connected to the limiting racks 21, and the side walls of the two square blocks 20 are fixedly connected to the second springs 22, and the two square blocks 20 are fixedly connected to the positions corresponding to the second springs 22, and the blocking blocks 24 are slidably connected to the top positions corresponding to the mounting grooves 19 on the mounting frame 1, and the second support rods 25 are rotatably connected to the positions corresponding to the mounting grooves 19 on the side of the mounting frame 1, and the plurality of second support rods 25 are fixedly connected to the limiting gears 26, and the plurality of second support rods 25 are fixedly connected to the positions close to the limiting gears 26, and the front-rear symmetrical second pull rods 27 are fixedly connected to the power rod 28.

[0019] Specifically, one end of the linkage rod 8 slides through the guide groove 6 and is fixedly connected to the lifting block 9, and the screw rod 11 is threadedly connected to the lifting block 9, so that the screw rod 11 can drive the linkage rod 8 to move through the lifting block 9.

[0020] Specifically, the top of the screw rod 11 is fixedly connected with a rotating handle 29, and the bottom end of the mounting frame 1 is provided with a plurality of symmetrically arranged universal wheels 30. The rotating handle 29 is convenient for rotating the screw rod 11, and the universal wheels 30 are convenient for supporting the movement of the mounting frame 1.

[0021] Specifically, the first springs 14 are located at the middle position between the baffle 13 and the mounting plate 10 , and the side ends of the first springs 14 are fixedly connected to the side walls of the mounting plate 10 , so that the first springs 14 can easily drive the baffle 13 to move and reset.

[0022] Specifically, the specific row shape of the connecting frame 15 is an L-shaped setting, and a movable groove 31 is opened at the position corresponding to the sliding groove 4 on the mounting frame 1. The front and rear symmetrical movable grooves 31 are slidably connected with movable plates 32, and the movable plates 32 are fixedly connected to the movable rod 5. The screw rods 11 are rotatably connected to the top of the movable plates 32. The connection between the movable plates 32 and the movable grooves 31 facilitates limiting the moving trajectory of the movable rod 5 to the inside of the sliding groove 4.

[0023] Specifically, the interior of the mounting groove 19 is fixedly connected with a vertical block 33, one end of the round rod 23 slides through the vertical block 33, the round rod 23 is located in the hollow position of the second spring 22, and the side ends of the second spring 22 are fixedly connected to the side walls of the vertical block 33.

[0025] Specifically, the power rods 28 are rotatably connected to the top end of the oblique side of the first pulling rod 18 , and the limiting gears 26 are meshingly connected to the limiting racks 21 .

[0026] When in use, when the mounting frame 1 moves on the elevation belt through the universal wheel 30, the screw rod 11 can be directly rotated by turning the handle 29, and the rotation of the screw rod 11 will drive the lifting block 9 and the connecting rod 8 to move downward together, and the downward movement of the connecting rod 8 will drive the telescopic rod 7 to move downward, and the telescopic rod 7 will slide downward inside the moving rod 5 and drive the mounting plate 10 to move downward together, and the movement of the mounting plate 10 will drive the connecting rod 12, the baffle 13, the first spring 14, the connecting frame 15 and the stabilizing wheel 16 to move downward together, and then the stabilizing wheel 16 is adjusted downward. When the screw rod 11 reaches the position corresponding to the two walls of the bridge deck, the rotation of the screw rod 11 can be stopped. At this time, the staff will lift the corresponding blocking block 24 upwards. At this time, the blocking block 24 is separated from the mounting frame 1, and the round rod 23 is no longer in contact with the blocking block 24. Then the staff can directly pull the power rod 28 on one side. At this time, the power rod 28 will drive the second support rod 25 to rotate through the two second pulling rods 27. The two second support rods 25 will drive the limit gear 26 to rotate. The rotation of the limit gear 26 will continuously squeeze the limit rack 21, and the limit rack 21 is The squeezing will drive the square block 20 to slide inside the installation groove 19 toward the vertical block 33. At the same time, the square block 20 will drive the round rod 23 to move, and the square block 20 will also squeeze and contract the second spring 22. The second spring 22 will also drive the square block 20 and the limit rack 21 to reset and move toward the limit gear 26 during the rotation of the limit gear 26. As the limit gear 26 continues to rotate, the limit rack 21 will continue to bounce back and forth. At the same time, the rotation of the power rod 28 will pull the two first pulling rods 18, and the two second pulling rods 18 will be pulled back and forth. When the pulling rod 18 is pulled, it will pull the moving rod 5 through the first support rod 17. At this time, the moving rod 5 will move toward the power rod 28. The two moving rods 5 will jointly drive the moving plate 32 to slide inside the moving groove 31. The sliding of the moving plate 32 can guide the movement of the moving rod 5. At the same time, the movement of the moving rod 5 will drive the mounting plate 10 to move together through the telescopic rod 7. The mounting plate 10 will drive the connecting rod 12, the connecting frame 15 and the stabilizing wheel 16 to move toward the power rod 28 until the stabilizing wheel 16 abuts against the side wall of the bridge deck. Figure 6The position of the two stabilizing wheels 16 on the other side is fixed. After the adjustment is completed, the mounting frame 1 is moved. The stabilizing wheels 16 of the mounting frame 1 will also be passively rotated due to the abutment of the side walls of the bridge deck. When the side walls of the bridge deck are uneven, the stabilizing wheels 16 will be squeezed by the uneven side walls of the bridge deck during the movement. The squeezed stabilizing wheels 16 will cause the connecting rod 12 and the baffle plate 13 to move toward the middle direction of the mounting frame 1. The movement of the baffle plate 13 will stretch the first spring 14. The movement of the baffle plate 13 and the connecting rod 12 can make the stabilizing wheel 16 more adaptable to the uneven side walls of the bridge deck. Then, the positioning vertical plate 3 is rotated by the articulated seat 2, and the steel bars on the bridge deck are controlled and positioned by the positioning vertical plate 3.
