[0002] The cantilever casting method with hanging basket is a construction technology widely used in the construction of continuous rigid frame bridges. The hanging basket is the key point in the cantilever casting construction, and its construction safety has a direct impact on the overall safety of the project. During the cantilever casting construction process with hanging basket, the walking of the hanging basket is the process with the highest risk factor. At this time, the anchor rods behind the hanging basket are in a relaxed state, and the rear of the hanging basket is buckled to the flange plate on the walking track by the reverse wheel to bear the force, which is equivalent to a sliding support. During the walking process, under the action of gravity when the center of gravity of the hanging basket tilts forward and slides down, the reverse wheel is prone to derailment, causing the hanging basket to become unstable and overturn.

[0003] Most of the existing hanging basket anti-overturning technologies are to pre-embed anti-overturning embedded parts before pouring the box girder, and then cooperate with other connecting parts to prevent overturning after pouring. In this method, the anti-overturning device cannot be moved flexibly when the hanging basket is moving, and it is inconvenient to install and disassemble; therefore, it is necessary to design a hanging basket walking anti-overturning device to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a hanging basket anti-overturning device, which solves the problem of the hanging basket in the prior art that the reverse buckle wheels derail and become unstable and overturn during the walking process. It has the characteristics of not needing to pre-embed embedded parts in advance and not being fixed to the hanging basket, and can move flexibly with the walking of the hanging basket.

[0006] Preferably, the shoulder pole beam comprises a double-jointed channel steel, the top of which is connected to an upper cover plate, the bottom of which is connected to a lower cover plate, and the side surface of which is connected to a stiffening plate; holes are opened at the cantilevered ends of the upper cover plate and the lower cover plate and are threadedly connected to the threaded steel bar.

[0007] Preferably, the inverted hanging box includes a top plate, side plates are connected on both sides of the top plate, two partitions are connected between the side plates, and pull plates are connected to the opposite side surfaces of the bottom of the side plates. The pull plates are located below the flange plate on the walking track and are suspended.

[0008] Preferably, the upper end of the threaded steel bar passes through the middle of the double-piece channel steel at the cantilevered end of the shoulder pole beam and is connected to the shoulder pole beam through a first nut; the lower end of the threaded steel bar passes through the top plate of the inverted hanging box and is fastened to the lower surface of the top plate through a second nut; steel pads are installed between the first nut, the second nut and the upper cover plate of the shoulder pole beam and the lower surface of the top plate.

[0009] Furthermore, the upper cover plate, the lower cover plate, the stiffening plate of the shoulder beam, and the top plate, the side plate, the partition plate, and the pull plate of the inverted hanging box are all made of steel plates.

Two threaded steel bars 3 are cantilevered and threadedly connected on both sides of the shoulder pole beam 1. The bottom end of the threaded steel bars 3 is threadedly connected to the inverted hanging box 4 through a second nut 52; the pull plate 44 of the inverted hanging box 4 is located below the upper flange plate 61 of the walking track 6.

[0018] Preferably, the shoulder beam 1 includes a double-jointed channel steel 11, the top of which is connected to an upper cover plate 12, the bottom of which is connected to a lower cover plate 13, and the side surface of the double-jointed channel steel 11 is connected to a stiffening plate 14; the cantilevered ends of the upper cover plate 12 and the lower cover plate 13 are both opened with holes and threadedly connected to the threaded steel bars.
