This hinged connection allows the other end of the ramp plate 5 to contact the ground, allowing vehicles to drive onto the top of the second concave plate 2 along the passage created by the ramp plate 5. The transition plate 4 is fixed to the top of the second concave plate 2, with its ends fixedly connected to the ends of the notch in the second trough plate, forming a passage for vehicles to pass through. The spring assembly 3 is arranged between the first concave plate 1 and the second concave plate 2 to play a buffering role and ensure the stable passage of vehicles. The protective device of the utility model is easy to install, has strong toughness and resistance to rolling pressure, protects the safe passage of vehicles such as water carts and hydraulic trucks, and speeds up the construction progress.

[0026] like Figure 1-2 As shown, in the embodiment of the present invention, the first concave plate 1 is embedded in the expansion joint to prevent construction waste from entering the expansion joint, and includes a first trough plate and a first wing plate 13. The first trough plate includes a first bottom plate 11, and first vertical plates 12 fixedly connected vertically to the top of both ends of the first bottom plate 11. The width of the first bottom plate 11 is consistent with the width of the expansion joint, and its top is fixedly connected to the bottom of the spring assembly 3 to support the spring assembly 3. A first wing plate 13 is fixedly provided vertically on the top of the outer side of the first vertical plate 1. Two groups of the first wing plates 13 are respectively overlapped on both sides of the expansion joint to prevent the first concave plate 1 from falling.

[0027] like Figure 1 、 3As shown, in the embodiment of the present invention, the second concave plate 2 is embedded in the first concave plate 1, and a spring assembly 3 is connected between the two. The second concave plate 2 can be stretched and retracted downward and buffered when subjected to force, so that the protective device has strong toughness and anti-rollover pressure, which can offset the vehicle's intended impact force and protect the vehicle's safe passage. The second concave plate 2 includes a second trough plate and a second wing plate 23, wherein the second trough plate includes a second bottom plate 21 and a second vertical plate 22 respectively fixedly connected to the top of the two ends of the second bottom plate 21; the bottom of the second bottom plate 21 is connected to the top of the spring assembly 3, transferring the impact load to the spring assembly 3 and converting it into elastic potential energy for buffering and vibration reduction; the second wing plate 23 is fixedly fixedly provided on the outer top of the second vertical plate 22.

[0028] The transition plate 4 is used to close the notch of the second concave plate 2 to form a channel, and its two ends are fixedly connected to the two ends of the notch of the second trough plate by welding; by closing the notch of the second concave plate 2 by the transition plate 4, a channel can be formed for vehicles to pass through, while preventing construction waste from entering the second concave plate 2 to exert pressure on the spring assembly 3, thereby avoiding the degradation of the buffering performance of the spring assembly 3.

[0029] The inclined plate 5 is hinged to the second wing plate 23 by a hinge 6, and its outer end contacts the ground under the action of gravity, thereby forming an upward channel for vehicles to drive onto the top of the transition plate 4. Preferably, the outer end of the inclined plate 5 is further provided with an inclined portion 501, which forms a slope to make it easier for vehicles to pass.

[0030] The spring assembly 4 is arranged between the first concave plate 1 and the second concave plate 2 to buffer the impact load so that the protective device has higher toughness and anti-crushing pressure. It includes multiple springs arranged in an array, and the spring type is a disc spring or a compression spring.

[0035] S300: Adjust the width of the first base plate 11 according to the width of the expansion joint, slide the sliding plate 112 out of the sliding cavity until the width of the first base plate 11 is the same as the width of the expansion joint, and insert the positioning pin 114 into the pin hole 113 and the corresponding positioning hole in sequence to lock it; after the adjustment is completed, insert the first concave plate 1 into the expansion joint;

Through the first concave plate 1 adapted to the width of the expansion joint and the second concave plate 2 adapted to the first concave plate 1, the first concave plate 1 can be quickly embedded in the expansion joint, and the second concave plate 2 can be embedded in the first concave plate 1, thereby completing the rapid installation of the protective device and reducing construction time and manpower requirements.

[0042] The protective device of the present invention is provided with a spring assembly 4 between the first concave plate 1 and the second concave plate 2, which transfers the impact load to the spring assembly 3 and converts it into elastic potential energy for buffering and vibration reduction, so that the protective device has higher toughness and anti-crushing pressure, and reduces the direct pressure on the expansion joint.
