Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a reinforcement cage hanger positioning device used for bridge construction. Background Art

[0002] In the construction of the pile foundation of the bridge structure, the pile foundation has been drilled. The conventional construction process for lowering the steel cage is to divide the steel cage skeleton into multiple sections, hoist and lower them, and use straight threaded sleeves to connect or weld the steel cage sections one by one to form an overall steel cage skeleton. After the crane lifts a section of the steel cage and lowers it into the pile hole, the steel section is used as a support rod and placed on both sides of the pile hole to support the steel cage. The support rod crosses the steel cage to form a fulcrum, which bears the deadweight of the steel cage section and stabilizes the steel cage. Then the crane hoists the next section of the steel cage and connects it with the steel cage section.

[0003] However, firstly, when conventional construction techniques are used to connect the steel cage, the support rods must pass through the main body of the steel cage. When the main bars of the steel cage are densely packed and the spacing is small, the support rods often cannot pass through normally and the spacing between the main bars needs to be adjusted locally. The passing of the support rods needs to be done manually. Secondly, when the steel section of the support rod is large in size and heavy in weight, it is difficult to manually push the support rods to adjust the spacing normally. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0018] See also Figure 1-3 A steel cage hanger positioning device for bridge construction comprises a hanger 1, grooves 7 are provided on the four sides of the inner cavity of the hanger 1, and the hanger 1 is movably sleeved with pull rods 3 through the four grooves 7, and one end of the four pull rods 3 is fixedly installed with a clamping plate 2, and the four clamping plates 2 are located inside the hanger 1, and the middle of the side where the four clamping plates 2 are close to each other is fixedly installed with a support rod 6, and the inner cavity of the four grooves 7 is fixedly installed with three installation rods 8, and the outer side of the installation rod 8 is movably installed with a roller 9, and the roller 9 is located inside the groove 7, and the clamping plate 2 is fixed by one end of the four support rods 6, and the pull rod 3 is fixed at one end of the four clamping plates 2, and grooves 7 are provided on the four sides of the inner cavity of the hanger 1, and the four pull rods 3 are movably connected with the hanger 1 through the four grooves 7, and the installation rods 8 are fixed at equal distances in the inner cavity of the groove 7, and the roller 9 is movably installed on the outer side of the installation rod 8, Therefore, when the pull rods 3 around are pulled, the rolling friction force replaces the previous sliding friction force, thereby achieving the effect of facilitating the pushing of the support rods 6. Two hollow rods 10 are fixedly installed on the four sides of the inner cavity of the hanger 1, and a fastening spring 11 is fixedly installed at the bottom of the inner cavity of the hollow rod 10. A connecting rod 12 is fixedly installed at one end of the fastening spring 11, and the other end of the connecting rod 12 is fixed to the clamp plate 2. Two connecting rods 12 are fixed on the side close to the inner cavity of the hanger 1 through the four clamp plates 2, and the fastening spring 11 is fixed at one end of the connecting rod 12, and the hollow rod 10 is fixed on the outside of the fastening spring 11, and the hollow rod 10 is fixed to the inner cavity of the hanger 1. Therefore, when the four support rods 6 pass through the steel cage, the clamp plates 2 around it clamp the steel cage through the elastic action of the fastening spring 11, so that the clamping of the steel cage passing through the inner cavity of the hanger 1 is more stable.

[0019] Among them, one end of the four pull rods 3 is fixedly installed with a pull ring 4, and the four pull rings 4 are all located on the outside of the hanger 1. By pulling the pull ring 4 at one end of the pull rod 3, the pull rod 3 can be pulled, making the whole process more labor-saving and convenient.

[0020] Among them, the four outer sides of the hanger 1 are fixedly installed with limiting sleeves 5, and the four pull rods 3 are movably connected to the four limiting sleeves 5 respectively. By installing the limiting sleeves 5, the pull rods 3 are prevented from being misplaced when moving, thereby limiting the pull rods 3.

[0021] The four clamping plates 2 are all of the same shape and size and are all arc-shaped. The steel cage can be clamped more stably by four identical arc-shaped plates.

[0022] The limiting sleeve 5 is located between the two connecting rods 12 , so that the four clamping plates 2 are subjected to uniform force.

[0023] Working principle: When the steel cage hanger positioning device for bridge construction is used, the pull rods 3 on all sides are stretched to enlarge the area formed by the four support rods 6. When the crane lifts a section of steel cage and lowers it into the inner cavity of the hanger 1, at the same time, the pull rods 3 on all sides are loosened to allow the four support rods 6 to move internally, so that the four support rods 6 pass through the steel cage, thereby supporting the steel cage. At this time, after the end of the support rod 6 passes through the steel cage, it limits the transverse steel bars of the steel cage, and finally quickly connects the steel cage. Since the clamps 2 on all sides are reset by the tightening springs 11, the clamps 2 on all sides can stably clamp the steel cage, thereby ensuring that the steel cage can be more stable when connected.
