This needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing bridge repair devices, which often involve simply pouring repair material into bridge cracks. However, due to varying crack sizes and insufficient filling pressure, the repair material is difficult to stably fill the bottom of the cracks, thus affecting the bridge repair effect. Therefore, this invention proposes a bridge construction repair device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bridge construction repair device, comprising a plate, a wheel mounted on the lower surface of the plate, a repair assembly disposed on the surface of the plate, the repair assembly including a material conveying box fixedly connected to the upper surface of the plate, a through hole opened on the upper surface of the plate, a positioning block fixedly connected to the inner wall of the through hole, a support rod slidably connected to the inner wall of the positioning block, a pressure plate fixedly connected to the lower end of the support rod, a guide pipe installed inside the material conveying box, and one end of the guide pipe fixedly connected to the pressure plate. Next, a flow channel is formed on the lower surface of the pressure plate, and the guide pipe is connected to the flow channel. A pressure roller is installed on the lower surface of the plate, and an auxiliary component is provided on the upper surface of the plate. By controlling the cylinder to push the pressure plate tightly against the bridge surface, the pressure plate can be accurately positioned on the damaged part of the bridge. The repair material in the material box enters the flow channel on the lower surface of the pressure plate through the guide pipe and is evenly applied to the damaged area, ensuring that the repair material can be accurately applied to the location that needs repair, avoiding waste of repair material and unnecessary expansion of the application area, and improving the accuracy of the repair work and the material utilization rate.

[0023] Please see Figures 1-5This utility model provides a technical solution: a bridge construction repair device, including a plate 1, a wheel 2 installed on the lower surface of the plate 1, and a repair component 3 provided on the surface of the plate 1. The repair component 3 includes a material conveying box 31, which is fixedly connected to the upper surface of the plate 1. A through hole 34 is opened on the upper surface of the plate 1, and a positioning block 36 is fixedly connected to the inner wall of the through hole 34. A support rod 37 is slidably connected to the inner wall of the positioning block 36, and a pressure plate 310 is fixedly connected to the lower end of the support rod 37. A guide pipe 35 is installed inside the material conveying box 31, and one end of the guide pipe 35 is fixedly connected to the pressure plate 310. The lower surface of the pressure plate 310... The plate 1 has a flow channel 311, and the guide pipe 35 is connected to the flow channel 311. The lower surface of the plate 1 is equipped with a pressure roller 312, and the upper surface of the plate 1 is equipped with an auxiliary component 4. By controlling the cylinder 42 to push the pressure plate 310 to fit tightly against the bridge surface, the pressure plate 310 can be accurately positioned at the damaged part of the bridge. The repair material in the material box 31 enters the flow channel 311 on the lower surface of the pressure plate 310 through the guide pipe 35 and is evenly applied to the damaged area, ensuring that the repair material can be accurately applied to the position that needs to be repaired, avoiding waste of repair material and unnecessary expansion of the application area, and improving the accuracy of the repair work and the material utilization rate.

[0024] In this embodiment: a lid 32 is installed on the material conveying box 31, and a handle 33 is fixedly connected to the upper surface of the lid 32. The lid 32 with the handle 33 makes it simple and convenient to open and close the material conveying box 31. Workers can quickly open the lid 32 to pour in the repair material and then quickly close it. The whole process is smooth and efficient, which improves the efficiency of the repair material preparation process.

[0025] Specifically, a stop block 38 is fixedly connected to the upper end of the support rod 37, and a spring 39 is fixedly connected to the lower surface of the stop block 38. The spring 39 is sleeved on the support rod 37, and the lower end of the spring 39 is fixedly connected to the surface of the positioning block 36.

[0026] Specifically, the auxiliary component 4 includes a positioning frame 41, which is fixedly connected to the upper surface of the plate 1. A cylinder 42 is fixedly connected to the lower surface of the positioning frame 41. The output end of the cylinder 42 is fixedly connected to the upper surface of the pressure plate 310, and the height of the pressure plate 310 is effectively controlled by the cylinder 42.

[0027] In this embodiment: a tie rod 43 is fixedly connected to the upper surface of the plate 1, and a pressure roller 312 installed on the lower surface of the plate 1 rolls the repair material after it is applied, which can make the repair material cover the bridge surface more evenly, and further compact the repair material so that it adheres tightly to the bridge structure. This not only improves the aesthetics of the repair area, but more importantly, it enhances the strength and durability of the repaired part and effectively extends the service life of the bridge.

[0028] Specifically, there are two levers 43, and the two levers 43 are mirror images of each other.

[0029] Specifically, there are four support rods 37 and four positioning blocks 36, which are mirrored to ensure stable operation of the equipment.

[0030] Working principle: By pulling the two mirror-mounted levers 43 on the plate 1, the plate 1 is moved. The wheels 2 installed on the lower surface of the plate 1 make the movement smoother, allowing the repair device to be conveniently transported to the location on the bridge that needs repair. Before starting the operation, open the cover 32 with handle 33 on the material conveying box 31 and pour the repair material into the material conveying box 31. The cover 32 can prevent the material from spilling and the impurities from getting in.

[0031] When the device moves above the area to be repaired, the control cylinder 42 pushes the pressure plate 310 downwards. The pressure plate 310 then presses firmly against the bridge surface. The repair material in the material delivery box 31 enters the flow channel 311 on the lower surface of the pressure plate 310 through the guide pipe 35. Because the pressure plate 310 is in close contact with the damaged part of the bridge, the repair material is evenly applied to the damaged area through the flow channel 311.

[0032] After the repair material is applied and initially compacted, the device is pushed forward. The pressure roller 312 installed on the lower surface of the plate 1 rolls the area where the repair material has been applied, making the repair material adhere more evenly and tightly to the bridge surface, improving the repair quality, and ensuring the uniformity and stability of the repair effect. The above steps are repeated to move the device to the next area that needs to be repaired, and the bridge repair work is continued until the entire bridge repair task is completed.
