Principle of operation
Placing the guide plate device at the joint of the slope and the flat road, turning down the slope support 19 to enable the guide plate device to be attached to the slope under the up-down sliding of the slope height adjusting block 30 and the rotating action of the slope support rotating shaft 20, placing the bottom shell 10 at the flat road, and withdrawing the sealing plate 11 after the placement is finished;
when a vehicle or a heavy object passes through the guide plate, the guide plate 16 is deformed due to downward pressure generated on the surface of the guide plate 16, but the guide plate 16 pushes the slide column 14 to move outwards to form a gentle slope due to the fact that the slope support 19 is fixed and the guide plate 16 is fixedly connected with the guide plate rotating shaft 17;
in the deformation process of the guide plate 16, the guide plate support columns 36 gradually contact with a plurality of guide plate support columns 36 below, the guide plate support columns 36 do not sink after sinking to a certain extent under the action of corresponding support column springs 38, so that a supporting force is generated on the guide plate 16, the guide plate 16 is prevented from being permanently deformed to cause the equipment to fail, and meanwhile, a certain gap is formed between the slope support rotating shaft 20 and a slope under the action of a slope support spring 39 on the bottom surface to prevent the equipment from being excessively crushed by vehicles;
in the process of outward movement of the slide column 14, the deformation linkage block 34 fixedly connected with the slide column is moved together, so that the part of the deformation linkage block 34 extending into the hydraulic channel 41 is moved outwards to extract internal hydraulic oil, therefore, the first hydraulic column 42 arranged at the other end of the hydraulic channel 41 is pulled back under the action of hydraulic pressure, meanwhile, the bottom ends of the first hydraulic column 42 and the second hydraulic column 32 are not closed, the second hydraulic column 32 and the press block connecting rod 31 are pulled back at the same time, the press block 29 fixedly connected with the press block connecting rod 31 is pulled back due to the fact that the press block connecting rod 31 is pulled back, so that the press column 26 moves horizontally, in the process of moving the press column 26, the press column 26 always generates a downward force to act on the upper surface of the deformation mud 24 due to the acting force of the press column spring 27, and the deformation mud 24 is gradually attached to the ground depression under the action of the press column 26 when the support of the sealing plate 11 below the deformation mud 24 is lost;
when the vehicle or the heavy object leaves the surface of the guide plate 16, the deformation linkage block 34 is pulled back under the action of the linkage block reset spring 35, so that the guide plate 16 is restored to the original state, the deformation linkage block 34 returns to the original position, so that the hydraulic oil in the first hydraulic column 42 and the second hydraulic column 32 loses tension to become thrust, and returns to the original position under the combined action of the first hydraulic column spring 43 and the second hydraulic column spring 33, and the pressing block connecting rod 31 is pushed out, so that the pressing block 29 returns to the original position, and the pressing column 26 presses the deformation mud 24 for the second time under the driving of the pressing block 29 to make the deformation mud more fit the ground;
after the repeated pressure action of the pressing column 26, the adhesion between the deformed mud 24 and the ground tends to be stable, deformation is reduced, and at the moment, the deformation sensor 45 arranged on one side of the deformed mud 24 sends a signal to the terminal to report the deformation degree of the deformed mud 24, so that the material quantity required for filling the recess at the position is analyzed and is convenient to repair.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
