[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] like Figures 1-4 The automatic grinding device for stiffening ribs before welding is shown. In this embodiment, the stiffening rib 2 is specifically described using a U-rib as an example: Automatic polishing device includes A base 1, which is a rectangular plate.

[0017] The conveying unit installed on the base 1 includes conveying rollers, a conveying motor 12, and support rollers 13. There is a pair of support rollers 13, which are distributed on both sides of the bottom end of the base 1 along the long axis of the stiffening ribs 2. An annular groove for the stiffening ribs 2 to be embedded is also opened in the middle of the outer circumference of the support rollers 13. The two sides of the support rollers 13 are installed on the bottom end of the base 1 through the cooperation of a pair of support plates 131. The top of the support plates 131 is welded and fixed to the base 1. The two sides of the support rollers 13 are movably connected to the support plates 131 through the cooperation of bearings.

[0018] There is a pair of conveying rollers, distributed on both sides of the stiffening rib 2, and the outer circumferential wall of the conveying rollers is in contact with the side wall of the stiffening rib 2. The conveying rollers are driven to rotate by the conveying motor 12 mounted on the base 1, and drive the entire base 1 to reciprocate along the stiffening rib 2. The conveying motor 12 is connected to the conveying rollers through the cooperation of the first connecting rod, and drives the first connecting rod to rotate synchronously with the conveying rollers.

[0019] A grinding unit mounted on the base 1 includes a grinding wheel 17 and a grinding motor 11. The grinding wheel 17 is disposed between two supporting rollers 13 and is distributed on both sides of the stiffening rib 2. The outer circumferential wall of the grinding wheel 17 is in contact with the side wall of the stiffening rib 2. The grinding wheel 17 is driven to rotate by the grinding motor 11 mounted on the base 1 to grind the surface of the stiffening rib 2. The grinding motor 11 is connected to the grinding wheel 17 through the cooperation of the second connecting rod 19 and drives the second connecting rod 19 to rotate synchronously with the grinding wheel 17.

[0020] A guide assembly is also provided on the base 1. The guide assembly includes guide plates distributed on both sides of the stiffening rib 2, and guide wheels 14 are also installed on the guide plates.

[0021] The guide plate includes an inclined plate 16 and a first flat plate 18 and a second flat plate 15 connected to the inclined plate 16 and distributed vertically. The top of the inclined plate 16 is connected to the base 1, and the inclined direction of the inclined plate 16 gradually tilts away from the conveyor roller from the connection point between the inclined plate 16 and the base 1. The inclined plates 16 of the two guide plates are arranged in a V-shape, and the guide wheel 14 is mounted on the second flat plate. The guide assembly is designed to provide guidance and support between the grinding device and the rib plate when the entire grinding device reciprocates along the rib plate 2, preventing the grinding device from shaking on the rib plate 2 and ensuring stable movement of the grinding device. The V-shaped arrangement of the inclined plates 16 of the two guide plates, combined with the horizontally arranged first flat plate 18 and second flat plate 15, forms a triangular structure, making the overall structure more stable.

[0022] The first plate 18 also has through holes for the first connecting rod and the second connecting rod 19 to pass through. The first plate 18 cooperates with the first connecting rod and the second connecting rod 19 to ensure that the conveying motor 12 and the grinding motor 11 can stably drive the rotation of the conveying roller and the grinding wheel 17, and to avoid the conveying roller and the grinding wheel 17 from shaking during operation, which would lead to unstable conveying or unstable grinding.

[0023] Working principle: When grinding the stiffening rib 2, firstly, the entire grinding device is placed on the rib plate of the stiffening rib 2, so that the support roller is supported on the top of the rib plate of the stiffening rib 2. The grinding wheel 17, the conveying roller and the guide roller 14 are respectively located on both sides of the rib plate of the stiffening rib 2. Then, the conveying motor 12 drives the conveying roller to rotate, thereby driving the base 1 to move along the rib plate of the stiffening rib 2. Then, the grinding motor 11 drives the grinding wheel 17 to rotate. During the movement of the base 1, the two sides of the rib plate of the stiffening rib 2 are automatically ground, eliminating the need for manual grinding.

[0024] In this embodiment, a controller can be added to the base 1 to cooperate with the conveying motor 12 and the grinding motor 11. A position sensor can also be added to the base 1 to detect the position of the base 1 on the rib plate of the stiffening rib 2. The detection signal can be used to control the forward and reverse rotation of the conveying motor 12 and the start and stop of the grinding motor 11, thereby realizing fully automatic processing.

[0025] This invention eliminates the traditional method of manual grinding and rust removal using hand-held grinding wheels and other tools in the grinding process before stiffening rib assembly and welding, greatly improving grinding efficiency. In the past, manual grinding was inefficient and consumed a lot of time and labor costs, while this invention can complete the grinding task quickly and efficiently, greatly shortening the entire production cycle of stiffening rib assembly and welding.

[0026] Secondly, it effectively ensures uniformity in rust removal. Manual grinding, due to the subjectivity and variability of operation, often results in inconsistent rust removal, affecting subsequent welding quality and the overall performance of the bridge. This invention, through precise technical means, achieves a high degree of consistency in rust removal on the stiffening rib surface, providing a reliable foundation for high-quality welding operations.

[0027] Furthermore, it significantly improves operational safety. Manually using hand-held grinding wheels and other tools for rust removal poses certain safety risks, such as wheel breakage and operator injury. This invention avoids direct contact with dangerous grinding tools, reducing the probability of accidents and providing a safer working environment for workers.

[0028] Finally, it has promoted technological progress in the railway and highway bridge construction industry as a whole. This utility model's innovative improvement to the stiffening rib grinding process not only enhances the efficiency and quality of bridge construction but also sets a new technological benchmark for the industry, promoting the continuous development and improvement of related technologies.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
