[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a bridge construction hoisting auxiliary device, including a base 1, a support rod 2, and a top rod 3. The support rod 2 is symmetrically fixedly connected to both sides of the base 1, and the top rod 3 is fixedly connected to the top of the support rod 2. Two crossbeams 4 are fixedly connected between the two top rods 3. Steel wire ropes 5 are symmetrically fixedly connected to both ends of the crossbeams 4. A set of steel wire ropes 5 is fixedly connected to a counterweight box 7 through a connecting assembly 6. The counterweight box 7 is fixed to one side of the top rod 3 through the connecting assembly 6 and the steel wire ropes 5. The bridge construction hoisting device is installed on the side of the top rod 3 away from the counterweight box 7, so that the two sides of the top rod 3 are balanced by gravity with the support rod 2 as the center point, avoiding tilting or swaying due to uneven force. Frequent adjustments to the posture are required to maintain balance, which not only increases the difficulty of operation but also reduces the hoisting efficiency.

[0020] The connecting assembly 6 includes an assembly plate 8, a hinge rod 9, a connecting seat 10, a fixing rod 11, and connecting bolts 12. The assembly plate 8 is located on the top of the counterweight box 7. The hinge rod 9 is fixedly connected to one side of the assembly plate 8, and the connecting seat 10 is located at the top of the hinge rod 9. The bottom end of the steel wire rope 5 is fixedly connected to the inner side of the connecting seat 10. The fixing rod 11 is fixedly connected to the other side of the assembly plate 8. Connecting bolts 12 are located at the top of the fixing rod 11 and the hinge rod 9. The bottom sides of the connecting seat 10 extend through the tops of the fixing rod 11 and the hinge rod 9, respectively. The top of bolt 12 passes through the bottom of connecting seat 10 and is threaded with a nut. The two sides of the bottom of connecting seat 10 are inserted into the top of fixing rod 11 and hinge rod 9 respectively. The two connecting bolts 12 are inserted into the top of fixing rod 11 and hinge rod 9 respectively. The connecting bolts 12 also pass through the two sides of the bottom of connecting seat 10. The nut is tightened on one end of the connecting bolt 12. The nut clamps the fixing rod 11, hinge rod 9 and the two sides of the bottom of connecting seat 10 to connect the mounting plate 8 to the bottom of connecting seat 10 as one unit, and fix the counterweight box 7 to one side of top rod 3.

[0021] The assembly plate 8 has symmetrical mounting holes on both sides. Fixing bolts are inserted into the mounting holes. The assembly plate 8 is fixedly connected to the counterweight box 7 by fixing bolts. The mounting holes are inserted into the mounting holes, and the fixing bolts are screwed into the counterweight box 7. The assembly plate 8 and the counterweight box 7 are fixed together by fixing bolts.

[0022] A door 13 is hinged to one side of the counterweight box 7, and a rotating pin 14 is hinged to one side of the door 13. A limiting frame 15 is fixedly connected to the side of the counterweight box 7 adjacent to the rotating pin 14. One end of the rotating pin 14 is inserted into the interior of the limiting frame 15, but the interior of the limiting frame 15 is not in contact with the inserted end of the rotating pin 14. Rotating the rotating pin 14 upwards will pull one end of the rotating pin 14 out of the interior of the limiting frame 15, thus terminating the connection between the door 13 and the counterweight box 7. At this time, the door 13 can be opened to increase or decrease the weight of the counterweight box 7. After that, the door 13 is closed, and the rotating pin 14 is rotated back to reset so that one end is reinserted into the interior of the limiting frame 15.

[0023] The counterweight box 7 has threaded rods 16 symmetrically fixedly connected to both sides inside. The counterweight box 7 has multiple counterweight blocks 17 inside. The counterweight blocks 17 have symmetrical slots 18 on both sides. The two sides of the counterweight blocks 17 are engaged with the outer sides of the two threaded rods 16 through the slots 18. Nuts are threaded to the top of the threaded rods 16. The multiple counterweight blocks 17 are engaged with the outer sides of the threaded rods 16 through the slots 18. The nuts are tightened on the top of the threaded rods 16 to press the counterweight blocks 17 and fix them inside the counterweight box 7. Loosening the nuts can pull the counterweight blocks 17 out from the outer sides of the threaded rods 16, increasing or decreasing the weight of the counterweight box 7 to maintain balance according to the weight of the hoisted materials.

[0024] The top and bottom ends of the support rod 2 are symmetrically fixed with reinforcing rods. One end of each reinforcing rod is fixedly connected to the top rod 3 and the bottom end of the base 1, respectively. The top and bottom ends of the support rod 2 form a triangular structure with the top rod 3 and the base 1 through the two reinforcing rods. The triangular structure is stable, making the structure of the base 1, support rod 2 and top rod 3 more stable.

[0025] The bridge construction hoisting auxiliary device involves inserting the two sides of the bottom end of the connecting seat 10 into the top of the fixed rod 11 and the hinge rod 9, respectively. Two connecting bolts 12 are then inserted into the top of the fixed rod 11 and the hinge rod 9, respectively. The connecting bolts 12 also pass through the two sides of the bottom of the connecting seat 10. Nuts are tightened at one end of the connecting bolts 12, clamping the fixed rod 11, the hinge rod 9, and the two sides of the bottom of the connecting seat 10. This connects the assembly plate 8 to the bottom of the connecting seat 10 as a whole. The counterweight box 7 is fixed to one side of the top rod 3, so that the two sides of the top rod 3 are balanced by gravity with the support rod 2 as the center point. This avoids tilting or swaying due to uneven force, which would require frequent adjustments to maintain balance. This not only increases the difficulty of operation but also reduces the hoisting efficiency.
