At this time, the worker The working platform 12 can be located below the ground of the bridge, and then the electric push rod 14 in the middle of the groove 13 can be operated, so that the extrusion plate 15 can be gradually moved toward the bridge deck guardrail. When the extrusion plate 15 moves toward the guardrail, the protective sheet 16 can be brought into contact with the guardrail. After the protective sheet 16 is in contact with the guardrail, the spring rod 18 can be used to protect the extrusion plate 15. When it is necessary to detect cracks at the bottom of the bridge, this step can be used to extrude the bridge deck guardrail between the extrusion plate 15 and the clamping block 11, and then the retaining block 1 can be fixed on the side of the guardrail, and then the working platform 12 can be fixed between the bridge deck. When detecting cracks at the bottom of the bridge, the need to drive the vehicle to the road surface can be reduced, and traffic pressure can be reduced during the detection of cracks at the bottom of the bridge.

[0024] like Figure 2-3As shown, a plurality of groups of elastic clips 2 are fixedly connected to the middle of the clamping block 11; an elastic support rod 21 is fixedly connected to the middle of the elastic clip 2; the elastic support rod 21 is fixedly connected to the clamping block 11; an arc-shaped clamping ring 22 is fixedly connected to the middle of the elastic clip 2; during operation, when the extrusion plate 15 and the clamping block 11 cooperate with each other to fix the retaining block 1 and the guardrail, the elastic clip 2 can be made to contact the outside of the guardrail, and during the extrusion process, the arc-shaped clamping ring 22 can increase the friction between the elastic clip 2 and the guardrail. This step can increase the friction between the clamping block 11 and the guardrail when the retaining block 1 needs to be fixed on the side of the guardrail, thereby improving the fixing effect of the clamping block 11 and reducing the shaking caused by unstable fixation during the detection of cracks on the bottom of the bridge.

[0025] like Figure 1-2 As shown, a servo motor 3 is fixedly connected to the middle part of the retaining block 1; a gear 31 is fixedly connected to the output end of the servo motor 3; a support rod 32 is rotatably connected to the middle part of the gear 31; the support rod 32 is fixedly connected to the retaining block 1; a tooth groove 33 is opened in the middle part of the slide bar 17; the gear 31 and the tooth groove 33 are meshed with each other; during operation, when detecting cracks at the bottom of the bridge, due to the different thicknesses of different bridge decks, the servo motor 3 can be operated, and the slide bar 17 can be driven to move up and down by the gear 31, and the support rod 32 can support the gear 31 when the gear 31 rotates. This step can be used when it is necessary to detect cracks at the bottom of the bridge of different thicknesses. By moving the slide bar 17 up and down, the height of the workbench 12 can be adjusted, thereby improving the applicability of the device and allowing detection of different bridges.

[0026] like Figure 1-4 As shown, the middle part of the workbench 12 is rotatably connected with a torsion spring 4; the middle part of the torsion spring 4 is fixedly connected with a hydraulic rod 41; the end of the hydraulic rod 41 is fixedly connected with a rubber sheet 42; during operation, when the staff is detecting cracks on the bottom of the bridge, the hydraulic rod 41 can be rotated by the torsion spring 4, and then the hydraulic rod 41 can be extended outward, and then the rubber sheet 42 can be used to contact the bottom of the bridge. In this step, when detecting cracks on the bottom of the bridge, the hydraulic rod 41 can be used to support the workbench 12, thereby reducing the possibility of dangerous situations caused by the workbench 12 moving upward due to accidental touch during the detection process.

[0027] like Figure 2 As shown, a slide groove 5 is opened in the middle of the slide rod 17; a card plate 51 is slidably connected to the middle of the slide groove 5; the card plate 51 is fixedly connected to the clamping block 11; during operation, when the gear 31 is used to move the slide rod 17 up and down, the card plate 51 can slide inside the slide groove 5. In this step, the card plate 51 can be used to support the side of the slide rod 17, thereby reducing the situation where the slide rod 17 and the gear 31 are separated from each other during the movement of the slide rod 17.

[0028] like Figure 1-2 As shown, the bottom of the retaining block 1 is fixedly connected to a limiting plate 6; the middle of the limiting plate 6 is slidably connected to a telescopic pad 61; during operation, when the retaining block 1 is clamped and fixed with the clamping block 11 and the guardrail, the telescopic pad 61 can be pulled out from the inside of the limiting plate 6, and then a counterweight block can be placed in the middle of the telescopic pad 61. This step can reduce the occurrence of tipping over of the retaining block 1 when detecting cracks in the bottom of the bridge.

[0029] like Figure 1 As shown, a warning reed 7 is fixedly connected to the middle of the workbench 12; during operation, after the staff completes the detection of cracks on the bottom of the bridge, the warning reed 7 can be vibrated. This step can make a sound through the vibration of the warning reed 7 to remind the staff above, thereby improving the detection efficiency of cracks on the bottom of the bridge.

[0030] Working principle: during operation, when it is necessary to detect cracks on the bottom of the bridge, the retaining block 1 can be placed on the side of the bridge, and then the clamping block 11 can be placed on the outside of the bridge guardrail. At this time, the workbench 12 can be located below the ground of the bridge, and then the electric push rod 14 in the middle of the groove 13 can be operated, so that the extrusion plate 15 can be gradually moved toward the bridge deck guardrail. When the extrusion plate 15 moves toward the guardrail, the protective sheet 16 can be made to contact the guardrail. After the protective sheet 16 contacts the guardrail, the spring rod 18 can be used to protect the extrusion plate 15. In this step, when it is necessary to detect cracks on the bottom of the bridge, the bridge deck guardrail can be squeezed between the extrusion plate 15 and the clamping block 11, so that the retaining block 1 can be fixed on the side of the guardrail, and then the workbench can be moved. 12 is fixed between the bridge deck, which can reduce the need to drive the vehicle to the road surface when detecting cracks at the bottom of the bridge, thereby reducing traffic pressure in the detection of cracks at the bottom of the bridge. When the extrusion plate 15 and the clamping block 11 cooperate with each other to fix the retaining block 1 and the guardrail, the elastic clip 2 can be made to contact the outside of the guardrail. During the extrusion process, the arc-shaped clamping ring 22 can increase the friction between the elastic clip 2 and the guardrail. This step can increase the friction between the clamping block 11 and the guardrail when the retaining block 1 needs to be fixed to the side of the guardrail, thereby improving the fixing effect of the clamping block 11, reducing the shaking caused by unstable fixation during the detection of cracks at the bottom of the bridge, and when detecting cracks at the bottom of the bridge, due to the instability The thickness of the bridge deck is different, so the servo motor 3 can be operated, and the slide bar 17 can be driven to move up and down through the gear 31. The support rod 32 can support the gear 31 when the gear 31 rotates. This step can be used to detect cracks on the bottom of the bridge of different thicknesses. The height of the workbench 12 can be adjusted by moving the slide bar 17 up and down, thereby improving the applicability of the device and allowing different bridges to be inspected. When the staff detects cracks on the bottom of the bridge, the hydraulic rod 41 can be rotated by the torsion spring 4, and then the hydraulic rod 41 can be extended outward, and then the rubber sheet 42 can be used to contact the bottom of the bridge. This step can be used to support the workbench 12 when detecting cracks on the bottom of the bridge, thereby The danger of the workbench 12 moving upward due to accidental touch during the detection process can be reduced. When the gear 31 is used to move the slide bar 17 up and down, the card plate 51 can slide inside the slide groove 5. In this step, the card plate 51 can be used to support the side of the slide bar 17, so as to reduce the separation of the slide bar 17 and the gear 31 during the movement of the slide bar 17. When the retaining block 1 is used, the clamping block 11 and the guardrail are clamped and fixed, the telescopic pad 61 can be pulled out from the inside of the limit plate 6, and then a counterweight block can be placed in the middle of the telescopic pad 61. This step can reduce the rollover of the retaining block 1 when detecting cracks in the bottom of the bridge. After the staff has completed the detection of cracks in the bottom of the bridge, the warning spring 7 can be vibrated.In this step, the warning reed 7 can vibrate and make a sound to remind the staff above, thereby improving the detection efficiency of cracks on the bottom of the bridge.
