[0028] The utility model is further described below in conjunction with embodiments.

[0029] See also Figure 1-6 The utility model provides a scaffold for repairing a roadbed and pavement in a settlement section, comprising a scaffold body 1, wherein positioning components 4 are installed at the four corners of the scaffold body 1, wherein the positioning components 4 comprise a through hole 41 located on the scaffold body 1, wherein both ends of the through hole 41 are provided with countersunk grooves 42, wherein a hollow column 43 is slidably embedded in the middle of the through hole 41, wherein both upper and lower outer walls of the hollow column 43 are fixedly sleeved with limiting rings 44, wherein a return spring 45 is sleeved between the limiting ring 44 and the end wall of the adjacent countersunk groove 42 and located on the outer side of the hollow column 43;

[0030] Specifically, the scaffolding plate is located at the junction of the sunken road surface and the normal road surface. The anchor nails are inserted through the hollow columns 43 and embedded in the roadbed, which can play the role of positioning the scaffolding plate body 1. When vehicles pass, the return spring 45 can play a buffering role. After the vehicle passes, the return spring 45 can drive the scaffolding plate body 1 to return to its original position.

[0031] Furthermore, the hollow column 43 is embedded with an anchoring nail, and the bottom end of the anchoring nail is embedded in the roadbed;

[0032] Specifically, by effectively positioning the hollow column 43 , the position of the butt plate body 1 can be limited to prevent the butt plate body 1 from shifting.

[0033] Furthermore, the front and rear sides of the strap body 1 are both provided with a first groove 11, and the front strap 2 and the rear strap 3 are hinged in the two first grooves 11 respectively, the length of the front strap 2 is greater than the length of the rear strap 3, and the front strap 2 and the rear strap 3 are both gradually narrowed from the strap body 1 outwards;

[0034] Specifically, the front slat 2 is naturally tilted on the sunken road surface, and the rear slat 3 is naturally tilted on the normal road surface. Since the height difference between the sunken road surface and the normal road surface is large, by extending the length of the front slat 2, the slope can be effectively reduced to avoid violent ups and downs of the vehicle.

[0035] Further, a second groove 12 is provided on the lower side of the strap body 1, and an elastic component 5 is installed on the top wall of the second groove 12. The elastic component 5 includes two connecting plates 51 fixed on the top wall of the second groove 12, and one side of both ends of the connecting plates 51 is rotatably connected to an inclined plate 52, and one side of the bottom end of the inclined plate 52 is rotatably connected to a roller 53, wherein connecting rods 54 are fixedly connected between adjacent inclined plates 52, and a plurality of tension springs 55 are fixed between the two connecting rods 54;

[0036] Specifically, under the action of the vehicle's own weight and inertia, the front strap 2 and the rear strap 3 will be compressed to change their inclination angles, thereby driving the strap body 1 to descend, and the angle between the two inclined plates 52 will increase. The rollers 53 will roll along the normal road surface, and the connecting rods 54 will move away from each other, which can pull the tension spring 55 to extend, and can play the role of flexible support together with the return spring 45, and can buffer the impact force to prevent the vehicle from jumping off. After the vehicle passes, under the elastic force of the tension spring 55 and the return spring 45, the strap body 1 will drive the front strap 2 and the rear strap 3 to reset, so that other vehicles can continue to pass.

[0037] Furthermore, the two inclined plates 52 are distributed in an "eight" shape, and the inclined plates 52 are in contact with the pressure plate 62. A rubber pad 64 is fixedly bonded to the side of the pressure plate 62 away from the slide bar 61, and the surface of the rubber pad 64 is densely covered with anti-slip protrusions.

[0038] Specifically, the anti-skid protrusions can increase the friction between the rubber pad 64 and the inclined plate 52 , thereby increasing the movement resistance of the inclined plate 52 and achieving a good damping effect.

[0039] Further, resistance increasing components 6 are installed on both sides of the elastic component 5 and on the strap body 1, and the resistance increasing components 6 include two slide bars 61 slidably embedded in the side walls of the second groove 12, and a pressure plate 62 is fixedly connected between the ends of the two slide bars 61 located in the second groove 12, and a damping spring 63 is sleeved on the outer side of the slide bar 61 and between the pressure plate 62 and the inner side wall of the second groove 12, and the damping spring 63 is used to push the pressure plate 62 to contact the movable part in the elastic component 5;

[0040] Specifically, the damping spring 63 pushes the pressure plate 62 to fit tightly against the inclined plate 52, and can provide sufficient friction during the rotation of the inclined plate 52, so that the inclined plate 52 can rotate slowly, thereby preventing the strap body 1 from violently rising and falling and causing discomfort to the passengers.

[0041] Working principle: When in use, the scaffold is located at the junction of the subsided road surface and the normal road surface. The anchor nails are inserted through the hollow column 43 and embedded in the roadbed, which can play the role of the scaffold body 1. The front scaffold 2 is naturally tilted on the subsided road surface, and the rear scaffold 3 is naturally tilted on the normal road surface. When a vehicle passes, the front scaffold 2 and the rear scaffold 3 play a role of slowing down, avoiding the appearance of step difference and improving the stability of vehicle passage. Under the action of the vehicle's own weight and inertia, the front scaffold 2 and the rear scaffold 3 will be compressed to change the inclination angle, which can drive the scaffold body 1 to descend, and the angle between the two inclined plates 52 increases, and the roller 53 moves along the normal When the road surface rolls, the connecting rods 54 move away from each other, which can pull the tension spring 55 to extend, and can play the role of flexible support together with the return spring 45 to buffer the impact force to prevent the vehicle from jumping off. After the vehicle passes, under the elastic force of the tension spring 55 and the return spring 45, the main body 1 of the strap will drive the front strap 2 and the rear strap 3 to reset, so that the remaining vehicles can continue to pass. On the other hand, the damping spring 63 pushes the pressure plate 62 to fit tightly against the inclined plate 52, and can provide sufficient friction during the rotation of the inclined plate 52, so that the rotation movement of the inclined plate 52 can be carried out slowly, which can prevent the main body 1 of the strap from violently fluctuating and causing discomfort to the passengers.
