[0002] Bailey frames are steel frames that form certain units and can be used to assemble into many components and equipment. Generally, when constructing a building, Bailey frames are used to assemble into Bailey beams, and construction is carried out on the Bailey beams to facilitate the construction of the building.

[0003] Bailey frames used in some construction processes, including transversely arranged Bailey frames and longitudinally arranged Bailey frames, are likely to be hit by various construction operations near the ground. For example, the Bailey frames on both sides above the bridge and the bottom of the Bailey frames used as longitudinal supports of various buildings are more susceptible to collisions. In order to prevent the Bailey frames close to the ground from being accidentally collided, resulting in deformation of the Bailey frames and causing the entire Bailey beam structure connected by the Bailey frames to become unstable, creating a safety hazard, a protective structure needs to be set on the Bailey frames for safety reasons. In order to provide good protection for the Bailey frames, a Bailey frame protection device is required. Utility Model Content

The technical solution is as follows:

[0005] A Bailey frame protection device includes a main board and a plurality of support plates hinged to the two ends of the main board in sequence, wherein slots are provided on one side surface of the support plates, the support plates at the two ends of the main board correspond to each other, and an insertion rod is inserted between the corresponding support plates at the two ends of the main board, and limiting grooves are symmetrically provided on both side surfaces of the two ends of the insertion rod, two limiting rods are slidably connected inside the slot, and the limiting rods can be clamped in the limiting grooves, and a driving mechanism for driving the limiting rod in and out of the limiting groove is provided on the side of the support plate away from the slot.

[0006] Furthermore, the driving mechanism includes a screw rod rotatably arranged on the side away from the slot and a slider slidably arranged inside the support plate, the slider is threadedly connected to the inner end of the screw rod, "L"-shaped connecting rods are symmetrically fixed at both ends of the slider, and the limit rod is provided with an inclined groove on a side close to the connecting rod, and one end of the connecting rod is slidably arranged in the inclined groove.

[0007] Furthermore, a spring is fixed between one end of the limiting rod and the inner wall of the supporting plate.

[0009] Furthermore, the support plate is provided with a chamber, and the connecting rod is slidably arranged in the chamber.

[0010] Furthermore, the main board and the support board are connected via a hinge.

[0011] The beneficial effects of the technical solution provided by the embodiment of the utility model are: the device can be conveniently set up on the Bailey frame, providing protection for the Bailey frame close to the ground, avoiding deformation of the Bailey frame due to collision, thereby making the Bailey beam unstable and causing safety hazards;

[0012] The device is placed around the Bailey frame for protection through the main board and the support plates hinged on both sides, and the device is fixed on the Bailey frame through the insertion rod. Once a collision occurs, the collision force will be applied to the support plates on both sides, and the steel bars on the Bailey frame will be subjected to less pressure and are not easily deformed.
