[0002] The 3rd bid section of Shiwu North is located at the E and G ramps of Baoxia Interchange, spanning the Shibai Expressway. The width of the box girder top plate is 12.75m. The hanging basket cantilever casting process is adopted. There are 4 suspenders on the front cross beam of the hanging basket for load bearing, and 1 high-strength steel bar is equipped at each end for use when the hanging basket walks. The material of the suspender is Q345, with a size of 180*20mm (width * thickness), an opening spacing of 15cm, and a φ50 pin is equipped. In the prior art, the adjustment of the suspender adopts a distribution beam combined with a jack. An adjustment beam is installed on the top surface of the distribution beam. After the hole positions are aligned with the steel hanging hole positions of the suspender, the pins are inserted. Finally, thin steel plates need to be repeatedly padded for fine adjustment, resulting in inconsistent stress levels of each suspender. Content of the Utility Model

[0003] The purpose of the utility model is to provide a tightening device for hanging basket suspenders, which can be used to adjust the position of the hanging basket suspenders and ensure that each suspender is stressed uniformly during the construction of the hanging basket.

One of the steel hanging holes of the hanging basket suspender is fixed to one of the through holes of the steel plate through a pin shaft.

[0005] As a further scheme of the utility model: it further includes a backing plate, which is arranged on the top surface of the distribution beam, and the large steel pipe is placed on the backing plate.

[0006] As a further scheme of the utility model: the bottom of the steel plate is of a convex structure, and the two ends of the bottom of the steel plate are welded and fixed to the top of the small steel pipe, and the convex part of the bottom of the steel plate penetrates into the small steel pipe.

[0007] As a further scheme of the utility model: it further includes stiffening plates, which are symmetrically arranged on both sides of the convex part of the bottom of the steel plate. One end of the stiffening plate is welded and fixed to the steel plate, and the other end of the stiffening plate is welded and fixed to the inner wall of the small steel pipe.

[0008] As a further scheme of the utility model: the backing plate has a groove at the place where the large steel pipe is placed, and the diameter of the groove is larger than the diameter of the large steel pipe.

[0009] As a further solution of the present utility model: a polytetrafluoroethylene plate is laid on the backing plate.

[0010] The present utility model has at least the following beneficial effects: when it is necessary to finely adjust the position of the hanging basket sling, in the hanging basket sling tightening device, by rotating the large steel pipe, the small steel pipe can move up and down, so as to adjust the position of the hanging basket sling, ensuring that the forces on each sling are consistent during the construction of the hanging basket.

[0011] 1. The profiled steel seat realizes the total length expansion and contraction by rotating between two circular steel pipes with matching sizes and threaded ends, and uses the threaded connection to bear the weight, so it is not easy to slip.

[0012] 2. This device solves the problems existing in the traditional method of padding steel plates, such as the padding being too high and uneven, resulting in inconsistent and unstable bearing of each sling.

[0013] 3. This device is convenient for installation and use, and does not affect the overall force of the sling.
