Specific implementation manner:

[0011] Refer to Figure 1 Figure 2 Figure 3 Figure 4 The described bridge guardrail with a protection function is characterized in that it includes two fixed vertical columns 1 and connecting devices 2 respectively connected to the middle of the upper surface of the outer side surface of each fixed vertical column 1. A connecting cross plate 3 is inserted in the middle of the outer side surface of each connecting device 2. A corrugated vertical plate 4 is connected to the middle of the outer side surface of each connecting cross plate 3. Track chutes 5 are provided in the middle of the inner side surfaces of the two fixed vertical columns 1. A protection device 6 is symmetrically inserted up and down in the middle of the two track chutes 5. An embedded device 7 is connected to the middle of the lower surface of each fixed vertical column 1. The connecting device 2 includes a support block 2-1, a groove 2-2, a clamping block 2-3, and a spring shaft 2-4. A groove 2-2 is provided in the middle of the outer edge of the upper surface of the support block 2-1. A clamping block 2-3 is inserted in the front edge above the groove 2-2. The clamping block 2-3 and the left and right side surfaces inside the groove 2-2 are connected to each other by a spring shaft 2-4. The inner side surface of the support block 2-1 is connected to the outer side surface of the fixed vertical column 1. The clamping block 2-3 is trapezoidal in shape. The protection device 6 includes a spring 6-1, a top plate 6-2, a rotating plate 6-3, and a slider 6-4. The left and right side surfaces of the spring 6-1 are each connected to a top plate 6-2 at the center of the circle. A rotating plate 6-3 is connected to the center of the circle of the outer side surface of each top plate 6-2. The outer end of the rotating plate 6-3 is inserted into the inner side surface of the slider 6-4. The slider 6-4 is T-shaped. The slider 6-4 is inserted into the track chute 5. A set screw is inserted above the front surface of the fixed vertical column 1. The set screw penetrates the side surface of the fixed vertical column 1 and contacts the slider 6-4. The embedded device 7 includes a backing plate 7-1, a sleeve 7-2, an embedded hook 7-3, and a through hole 7-4. The sleeve 7-2 is symmetrically connected to the front and back at the left and right of the lower surface of the backing plate 7-1. An embedded hook 7-3 is inserted into the center of the lower surface of each sleeve 7-2. Through holes 7-4 are provided at the four corners of the lower surface of the backing plate 7-1. The fixed vertical column 1 is connected to the middle of the upper surface of the backing plate 7-1.

[0012] When in use, the staff first places the pad 7-1 on the embedded device 7 in the embedded pit, makes the lower surface of the pad 7-1 consistent with the height of the embedded pit and injects concrete into the embedded pit, buries the embedded hook 7-3 and the sleeve 7-2 separates the embedded hook 7-3 from the pad 7-1 when the concrete is dry, and then after the concrete is dry, the bolt penetrates the through hole 7-4 and is tightened on the concrete, and then the staff inserts the connecting cross plate 3 into the outer end of the support block 2-1 on the connecting device 2, and at the same time, squeezes the block 2-3 into the groove 2-2 during the process of inserting the connecting cross plate 3 on the support block 2-1, and when the block 2-3 is separated from the connecting cross plate 3, the spring shaft 2-4 rotates the block 2-3 to rotate the block 2-3 out of the groove 2-2, and the block 2-3 is stuck on the inner surface of the connecting cross plate 3 for use.

[0013] When the vehicle only damages the corrugated vertical plate 4, the staff inserts their hand into the inner surface of the connecting cross plate 3, then places their thumb on the block 2-3 and presses it to insert the block 2-3 into the groove 2-2, and finally pushes the connecting cross plate 3 with their arm to remove the connecting cross plate 3 and the corrugated vertical plate 4 for replacement.

[0014] When the impact force is large, the spring 6-1 on the protective device 6 prevents the two fixed columns 1 from squeezing each other, and when storing, the staff rotates the spring 6-1 and the top plate 6-2 drives the rotating plate 6-3 to rotate in the slider 6-4 to merge the two fixed columns 1 to reduce the volume. The length of the spring 6-1 is half the length of the fixed column 1.

[0015] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
