Technical Field
[0001] This utility model relates to the field of forming tool technology, specifically to an integrated forming device for rounding and leveling the top corners of a railway box girder protective wall. Background Technology
[0002] The construction of precast box girder bridge deck mainly includes the construction of bridge deck ancillary facilities, bridge deck paving and related ancillary structures. The construction of the protective wall of the precast box girder bridge deck usually includes the following steps: surveying and setting out, roughening the concrete at the bottom of the wall, tying the reinforcing bars and pouring concrete. The construction of the protective wall needs to be carried out in accordance with the specific project conditions, and the appropriate construction method should be selected. The operation should be carried out in strict accordance with the design and specification requirements to ensure the construction quality and structural safety.
[0003] However, in the existing technology, the finishing quality of the protective wall in the construction of precast box girder bridge deck has a significant impact on the appearance and durability of the entire bridge deck. Traditional leveling tools will form right angles when finishing the wall surface. However, in actual use scenarios, right angles are prone to collision damage. In addition, right angles are also lacking in aesthetics. To address these issues, we propose an integrated forming device for rounding and leveling the top corners of the protective wall of railway box girders. Utility Model Content

[0006] The grip base connects the handle to the blade plane, and the connecting block connects the protective cover to the top of the flat chamfering assembly.
[0007] Preferably, the grip base includes a connecting plate and a limiting baffle, the connecting plate is fixed at the center line of the blade plane, and the limiting baffle is vertically disposed at one end of the connecting plate.
[0008] Preferably, the grip base further includes a locking protrusion, which is disposed on the inner side of the connecting plate.
[0009] Preferably, the handle includes a support leg, a locking groove, and a handle, with a groove formed on the bottom edge of the support leg, and the bottom of the support leg is connected to the pivot of the connecting plate.
[0010] Preferably, a locking groove is provided on the outer side of the support leg, and the locking groove corresponds to the position of the locking protrusion.
[0011] Preferably, the handle is located on the top inner side of the two support legs, and the outer side of the handle is provided with an anti-slip groove.
[0012] Preferably, the protective cover plate includes a cover plate body, a connecting groove and a connecting shaft. The cover plate body is located on the side of the blade plane and is arc-shaped.

[0013] Preferably, the connecting groove is formed inside the cover plate body, the connecting groove is connected to the connecting block, and the connecting shaft passes through the connecting block and the connecting groove to connect the connecting block and the connecting groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. In this utility model, the flattening and chamfering work area of the integrated forming device is formed by the blade plane and the flattening and chamfering component. When in use, align the rounded corner of the flattening and chamfering component with the starting position of the edge of the top surface of the protective wall, so that the blade and the wall surface are at an appropriate tilt angle. Then, push the device along the edge of the top surface of the protective wall at a uniform speed and force. The arc structure of the flattening and chamfering component is used to gradually round the wall surface. At the same time, the blade plane of the blade performs a flattening operation on the wall surface to make the flatness of the wall surface meet the requirements. During the operation, the construction personnel can adjust the pushing force and direction in a timely manner according to the actual situation to ensure the uniformity and consistency of the rounded corner and flattening effect. By gradually rounding the wall surface, the corners of the wall are less likely to be damaged by collision.
[0016] 2. In this utility model, the handle can rotate on the grip base by the pivot of the support leg and the connecting plate, and the handle can be folded when stored for easy carrying. The support leg and the connecting plate are fixed by the locking protrusion and the locking groove to prevent the handle and the grip base from loosening during use. The protective cover can be rotated on the connecting block by the connecting groove and the connecting shaft, so that the protective cover can be opened. The two ends of the protective cover are provided with end plate structures that wrap around the edge of the flat chamfering component. The protective cover protects the flat chamfering component and prevents it from being bumped when carried. Attached Figure Description
