Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, and more specifically, particularly relates to a steel plate splicing device for bridges. Background Art

[0002] Steel plates have the characteristics of large span, high bearing capacity, and fast construction speed. They are mainly used in bridge construction projects. With the increase in the size of bridges being built, the requirement for their bearing capacity is also getting higher and higher. Therefore, it is necessary to improve the bearing capacity to better meet our needs. Bridge steel plates are used more and more widely in bridge construction projects. Usually, during the production process of steel plates, it is necessary to splice the steel plates so that the steel plates can be applied to different occasions.

[0003] However, there are various types of splicing devices in the prior art. For example, the utility model patent CN217167182U relates to a steel plate splicing device for bridges. This utility model can adjust the distance between two groups of clamping plates through the cooperation of a connecting block, a servo motor, a nut, and a bidirectional lead screw, so that the clamping plates can clamp steel plates of different lengths. At the same time, through the cooperation of a pressing component, it can press and fix steel plates of different thicknesses again, which is convenient for the device to position the steel plates, make the positions of the steel plates square, and improve the splicing efficiency of the device.

[0004] Although this steel plate splicing device can position steel plates of different lengths and thicknesses for convenient splicing, this splicing device can only perform horizontal splicing on bridge steel plates. The splicing pattern of the steel plates is single, it cannot be applied to different occasions, it is not convenient to adjust the splicing angle of the steel plates, and position and fix them to change the splicing pattern. The usage limitations are large. In order to avoid this phenomenon, it is very necessary to design a steel plate splicing device for bridges. Summary of the Utility Model
