Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a road bridge construction device for reinforcing bridge cracks. Background Technology

[0002] During the long-term use of roads and bridges, cracks are prone to appear in the bridge structure due to factors such as vehicle load, environmental erosion, and material aging.

[0003] The existing construction equipment only focuses on the crack filling process. After the material is poured in the pouring tank, no corresponding road surface leveling device is set up. Because the surface of the reinforcement material is uneven after pouring, the uneven parts of the road surface will bear greater local stress when vehicles pass by, causing the reinforcement material to break prematurely and greatly reducing the effect of crack repair. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing construction device only focuses on crack filling and lacks a road surface flattening device. After pouring, the material surface is uneven, and the local stress increases when vehicles pass, which leads to early material damage and affects the crack repair effect. Therefore, we propose a road and bridge construction device for reinforcing bridge cracks.

[0005] To achieve the above objectives, this application adopts the following technical solution: a road and bridge construction device for reinforcing bridge cracks, comprising a pusher, a pouring tank fixedly connected to the top of the pusher, a U-shaped frame fixedly connected to the top of the pusher, a through slot on the top of the pusher, a moving slot on the top of the U-shaped frame, a moving rod slidably connected inside the moving slot, a handle fixedly connected to the top of the moving rod, a cavity block fixedly connected to the bottom of the moving rod, a pressure roller rotatably connected to the internal shaft of the cavity block, a slot at one end of the U-shaped frame, a locking groove at one end of the inner cavity of the slot, and a movable slot at one end of the moving rod;

[0006] The movable slot is equipped with a fixing mechanism for fixing the position of the moving rod.

[0007] Preferably, the fixing mechanism includes a thrust spring installed inside the movable groove, and one end of the thrust spring is fixedly connected to a locking block.

[0008] Preferably, sliding grooves are provided on both sides of the inner cavity of the movable groove, and sliders are fixedly connected to both sides of the locking block.

[0009] Preferably, the bottom of the card block is provided with an arc-shaped surface.

[0010] Preferably, the external shape of the card block matches the internal shape of the card slot.

[0011] Preferably, limit grooves are provided on both sides of the inner cavity of the movable groove, and limit blocks are fixedly connected to both sides of the movable rod.

[0012] Preferably, the bottom of the handle is fixedly connected to two return springs, and the bottom of the return springs is fixedly connected to the top of the U-shaped frame.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the operator moves the handle downwards, which in turn moves the hollow block and pressure roller down via the moving rod to compact the cracks in the bridge. At the same time, the movable groove and the thrust spring also move downwards. After the locking block contacts the locking groove, it pushes the slider to slide in the groove, causing the thrust spring to deform. The locking block eventually engages in the locking groove, fixing the position of the moving rod and ensuring the stability of the hollow block and pressure roller, thus continuing to compact the cracks and preventing dust from entering.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figures 1-5As shown, this utility model provides a technical solution: a road bridge construction device for reinforcing bridge cracks, including a pusher 1, a pouring tank 2 fixedly connected to the top of the pusher 1, a U-shaped frame 3 fixedly connected to the top of the pusher 1, a through groove 4 opened on the top of the pusher 1, a moving groove 5 opened on the top of the U-shaped frame 3, a moving rod 6 slidably connected inside the moving groove 5, a fixed handle 7 fixedly connected to the top of the moving rod 6, a cavity block 8 fixedly connected to the bottom of the moving rod 6, a pressure roller 9 rotatably connected to the internal shaft of the cavity block 8, a slot 10 opened at one end of the U-shaped frame 3, a slot 11 opened at one end of the inner cavity of the slot 10, and a movable groove 12 opened at one end of the moving rod 6. The movable groove 12 is equipped with a fixing mechanism for fixing the position of the movable rod 6. The fixing mechanism includes a thrust spring 13 installed inside the movable groove 12. One end of the thrust spring 13 is fixedly connected to a locking block 14. When the operator moves the handle 7 downward, the handle 7 drives the movable rod 6 to slide downward inside the movable groove 5. The movable rod 6 drives the cavity block 8 and the pressure roller 9 to move downward. The pressure roller 9 compacts the surface of the bridge crack. At the same time, the movable rod 6 drives the movable groove 12 to move downward. The movable groove 12 drives the thrust spring 13 and the locking block 14 to move downward. When the bottom of the locking block 14 is in contact with the groove 1... When the internal contact of 1 is made, it is squeezed by the inner wall of the slot 11. The locking block 14 drives the slider 20 to slide towards the opposite end inside the slot 19. The locking block 14 squeezes the thrust spring 13, causing the thrust spring 13 to undergo elastic deformation. When the locking block 14 moves completely into the inside of the slot 11, the thrust spring 13 drives the locking block 14 to reset through its own elastic force. The locking block 14 is locked inside the slot 11, fixing the position of the moving rod 6, thereby fixing the position of the cavity block 8 and the pressure roller 9. At this time, the pressure roller 9 compacts the crack in the bridge to prevent dust from entering the crack.

[0023] Reference Figure 5 As shown in this embodiment: sliding grooves 19 are provided on both sides of the inner cavity of the movable groove 12, and sliders 20 are fixedly connected to both sides of the locking block 14. Through the sliding grooves 19 provided on both sides of the inner cavity of the movable groove 12, and the sliders 20 fixedly connected to both sides of the locking block 14, the sliders 20 can slide inside the sliding grooves 19, so that when the locking block 14 is squeezed by the inner wall of the locking groove 11, it can drive the sliders 20 to slide towards the opposite end inside the sliding grooves 19, thereby enabling the locking block 14 to smoothly enter the interior of the locking groove 11.

[0024] Reference Figure 5 As shown in this embodiment, the bottom of the card block 14 is provided with an arc-shaped surface 15. The arc-shaped surface 15 allows the card block 14 to slide more smoothly to the opposite end when it is squeezed by the inner wall of the card groove 11, thereby reducing the friction between the card block 14 and the inner wall of the card groove 11 and improving the smoothness of the card block 14 entering the card groove 11.

[0025] Reference Figure 4 and Figure 5 As shown, in this embodiment, the external shape of the card block 14 matches the internal shape of the card slot 11. This design ensures that the card block 14 can be accurately and securely inserted into the card slot 11, and is not prone to shaking or falling off, thereby enhancing the stability and reliability of the device.

[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: limiting grooves 16 are opened on both sides of the inner cavity of the moving groove 5, and limiting blocks 17 are fixedly connected to both sides of the moving rod 6. Through the limiting grooves 16 opened on both sides of the inner cavity of the moving groove 5, and the limiting blocks 17 fixedly connected to both sides of the moving rod 6, the limiting blocks 17 can slide inside the limiting grooves 16. This design can not only effectively prevent the moving rod 6 from deviating or shaking during the movement, thus ensuring that the moving rod 6 can move smoothly and accurately to the designated position, but also further improve the stability and reliability of the device.

[0027] Reference Figure 4 As shown in this embodiment, two return springs 18 are fixedly connected to the bottom of the handle 7. The bottom of the return springs 18 is fixedly connected to the top of the U-shaped frame 3. Through the two return springs 18 fixedly connected to the bottom of the handle 7 and the fixed connection between the bottom of the return springs 18 and the top of the U-shaped frame 3, this design allows the handle 7 to automatically reset under the elastic force of the return springs 18 after the operation is completed, without the need for manual repositioning of the handle 7, thereby greatly improving construction efficiency and reducing the labor intensity of operators.

[0028] Working principle: By moving handle 7 downwards, the operator causes the moving rod 6 to slide downwards inside the moving groove 5. The moving rod 6 moves the cavity block 8 and pressure roller 9 downwards, and the pressure roller 9 compacts the surface of the bridge crack. At the same time, the moving rod 6 moves the movable groove 12 downwards, which in turn moves the thrust spring 13 and the locking block 14 downwards. When the bottom of the locking block 14 contacts the inside of the locking groove 11, it is squeezed by the inner wall of the locking groove 11. The locking block 14 causes the slider 20 to slide away from each other inside the sliding groove 19. The locking block 14 squeezes the thrust spring 13, causing the thrust spring 13 to undergo elastic deformation. When the locking block 14 is fully depressed, the spring is fully depressed. When the block 14 is fully moved into the slot 11, the thrust spring 13 uses its own elasticity to reset the locking block 14. The locking block 14 engages inside the slot 11, fixing the position of the moving rod 6, thereby fixing the positions of the cavity block 8 and the pressure roller 9. At this time, the pressure roller 9 compacts the crack in the bridge to prevent dust from entering the crack. Through the sliding grooves 19 opened on both sides of the inner cavity of the movable groove 12, and the sliders 20 fixedly connected to both sides of the locking block 14, the sliders 20 can slide inside the sliding grooves 19. This allows the locking block 14 to be squeezed by the inner wall of the slot 11, causing the sliders 20 to slide towards one end of the sliding groove 19. The arc-shaped surface 15 allows the locking block 14 to smoothly enter the interior of the slot 11. This design enables the locking block 14 to slide more smoothly towards the opposite end when squeezed by the inner wall of the slot 11, reducing friction between the locking block 14 and the inner wall of the slot 11 and improving the smoothness of its entry into the slot 11. The external shape of the locking block 14 matches the internal shape of the slot 11, ensuring that the locking block 14 can be accurately and securely locked into the slot 11, preventing shaking or falling out, thus enhancing the stability and reliability of the device. This is achieved through the limiting grooves 16 on both sides of the inner cavity of the moving groove 5 and the limiting blocks 17 fixedly connected to both sides of the moving rod 6. The limiting block 17 can slide inside the limiting groove 16. This design can not only effectively prevent the moving rod 6 from deviating or shaking during the movement, thus ensuring that the moving rod 6 can move smoothly and accurately to the designated position, but also further improve the stability and reliability of the device. Through the two return springs 18 fixedly connected to the bottom of the handle 7, and the fixed connection between the bottom of the return spring 18 and the top of the U-shaped frame 3, this design allows the handle 7 to automatically reset under the elastic force of the return spring 18 after the operation is completed, without the need for manual return of the handle 7 to its original position, thereby greatly improving construction efficiency and reducing the labor intensity of operators.
