[0034] Embodiment two

[0035] As Figure 4As shown, based on the same concept as the above embodiment, this embodiment further proposes: a supporting mechanism, the supporting mechanism is installed on one side of the mounting plate 3, the supporting mechanism includes a second slide groove 13, the surface of the mounting plate 3 is provided with a second slide groove 13, and the second slide groove 13 is provided with two groups, the interior of the second slide groove 13 is embedded with a fixing seat 14, and the fixing seat 14 is fixedly installed on one side of the main bridge body 1 by screws, the outer side of the fixing seat 14 is fixedly installed with a first connecting shaft 15, and the interior of the first connecting shaft 15 is hingedly connected to an electric telescopic rod 16, and the bottom of one side of the connecting plate 5 is fixedly installed with a second connecting shaft 17, and the second connecting shaft 17 is provided with two groups on the left and right, and the output end of the electric telescopic rod 16 is hingedly connected to the interior of the second connecting shaft 17, the second connecting shaft 17 is a rod-shaped device driven by an electric motor and capable of automatically extending and retracting within a certain range.

[0036] The width of the second sliding groove 13 is the same as that of the fixing seat 14 , thereby achieving a positioning function for the fixing seat 14 so that the installation position of the fixing seat 14 will not be vertically offset.

[0037] Special Note: The widening section shares the same structural form, span, and cross-sectional height as the main bridge section. The widening section has corresponding piers and abutments in the longitudinal direction. This means both the main bridge section and the widening section can independently bear their respective deck loads. The widening connector serves to connect the bridge superstructure and coordinate deformation.

[0038] The widening connector is a steel structure, with component dimensions calculated based on the bridge width and span. Once the connector and widening body are installed, additional bridge deck concrete is laid on top to smoothly connect with the main bridge deck, increasing the bridge width, improving traffic capacity, and driving comfort.

[0039] Working principle: First, determine the expected distance between the main bridge body 1 and the widening body 2, and then install the two sets of fixing seats 14 in the second slide groove 13 at the same time, determine the position of the fixing seat 14 according to the distance, and use screws to fix the fixing seat 14 on the main bridge body 1, and then start the electric telescopic rod 16. The output end of the electric telescopic rod 16 can drive the connecting plate 5 to move outward, and at the same time make the slider 8 slide in the first slide groove 9. The slide rod 10 will also slide in the limit groove 11 at the same time, and the connecting plate 5 will pull the spring 12. After the connecting plate 5 is moved to one side of the widening body 2 by the electric telescopic rod 16, the connecting plate 5 is combined with the bottom of one side of the widening body 2. The bolt 7 can be used to penetrate the fixing block 6 and inserted into the widening body 2 through the thread to complete the installation of the connecting device. The above is the entire working principle of the present utility model.
