Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance equipment, in particular to a bridge pier maintenance device. Background Art

[0002] Bridge pier maintenance is a critical step in ensuring the durability and safety of the pier structure. Common methods include watering and wrapping with plastic film. Watering is the most basic maintenance method. By regularly watering the pier surface, the concrete surface is kept moist, allowing the cement in the concrete to fully hydrate. This water replenishes the water lost due to evaporation during the hardening process, preventing shrinkage cracks caused by water loss. Plastic film has excellent sealing properties and can prevent the evaporation of water from the concrete. The water in the concrete forms a relatively stable humidity environment within the film, which is conducive to the hydration reaction of the cement.

[0003] The current use of high-pressure water guns for watering is associated with high equipment costs and significant water waste. Furthermore, some piers are located in locations that are not suitable for trucks carrying high-pressure water guns. While the use of film curing is cost-effective, it presents numerous practical challenges, such as air trapping due to loose adhesion, the risk of film damage, and the difficulty in observing the concrete surface during curing due to the film covering the concrete pier surface. To address these issues, a bridge pier curing device was proposed to meet practical needs. Utility Model Content

DETAILED DESCRIPTION

[0018] Embodiment 1, by Figure 1-4 It is given that the utility model includes a pier column fixing frame 1 fixedly installed on the surface of the pier column body 100, a walking track 3 located above the pier column fixing frame 1 and a walking trolley 5 that runs on the top of the walking track 3. The pier column fixing frame 1 and the walking track 3 are fixedly installed by a connecting rod 4. A connecting seat tube 9 is fixedly installed on the top of the walking trolley 5. One end of the connecting seat tube 9 is fixedly connected to a water outlet pipe 6. The end of the water outlet pipe 6 is provided with a water outlet nozzle 7. The other end of the connecting seat tube 9 is fixedly connected to a water inlet pipe 8. The water inlet pipe 8 is connected to a high-pressure water source.

[0019] In this embodiment, the trolley 5 moves at a constant speed on the track 3, delivering water through the water inlet pipe 8. The water then flows through the connecting seat tube 9 and, through the water outlet pipe 6, sprays the pier shaft through the water nozzle 7 for maintenance. This achieves 360-degree maintenance of the pier, ensuring the quality of the pier. The water inlet pipe 8 is flexible, allowing for appropriate movement during the movement of the trolley 5. The water outlet pipe 6 is rigid, ensuring that the water outlet nozzle 7 is directed toward the pier column body 100.

[0020] The cross-section of the walking track 3 is I-shaped, and the walking trolley 5 includes a moving seat 51. A mounting cover 52 is fixedly installed on the top of the moving seat 51, and mounting legs 53 are fixedly installed at the four corners of the bottom of the moving seat 51. Auxiliary wheels 54 are rotatably installed on the sides of the mounting legs 53. The surface of the auxiliary wheel 54 fits with the side of the walking track 3. A bearing seat 55 is fixedly installed on the top of the moving seat 51, and a roller 56 is rotatably installed on the side of the bearing seat 55. A groove for the rotation of the roller 56 is provided on the top of the moving seat 51, and the bottom of the roller 56 fits with the top of the walking track 3. There are two rollers 56, which are symmetrically installed above the moving seat 51.

[0021] In this embodiment, the walking track 3 is a standard track. The four auxiliary wheels 54 are respectively located on both sides of the walking track 3, which can maintain the balance of the walking trolley 5 and lower the center of gravity of the walking trolley 5 to further enhance stability. The two rollers 56 symmetrically installed on the top are used to reduce the friction between the walking trolley 5 and the walking track 3, and can further maintain balance.

[0022] A driving servo 57 is fixedly mounted on the top of the movable seat 51 , and a synchronous pulley 58 is fixedly mounted on the output end of the driving servo 57 . The output end of the driving servo 57 drives one of the rollers 56 to rotate via the synchronous pulley 58 .

[0023] In this embodiment, the driving servo 57 also includes necessary devices such as its drive, remote control circuit board and power supply. By driving the servo 57 and the synchronous pulley 58, any roller 56 can be driven to rotate, thereby driving the walking trolley 5 to move at a constant speed on the walking track 3.

[0024] Example 2: Based on Example 1, the pier column fixing frame 1 includes a circular rod and a straight rod. There are two circular rods, which are fixedly mounted on the surface of the pier column body 100. A straight rod is mounted between the two circular rods via a socket structure. The socket structure includes an insert 11 and a slot 12. The insert 11 is fixedly mounted on one end of the pier column fixing frame 1, and the slot 12 is provided at the other end of the pier column fixing frame 1. The insert 11 is provided with a first mounting groove 111. The openings at both ends of the first mounting groove 111 are movably connected to cylindrical protrusions 112. A first spring 113 is provided between the two cylindrical protrusions 112. Second mounting grooves 121 are provided on the upper and lower sides of the slot 12. A second spring 123 is movably connected to the surface of the second mounting groove 121, and one end of the second spring 123 is pressed against the interior of the second mounting groove 121.

[0025] In this embodiment, when installing the ring rod and the straight rod, the installation can be completed by inserting the plug block 11 into the slot 12. The installation is simple and quick. After installation, by pressing the two 122 at the same time, the round head end of the cylindrical protrusion 112 can be squeezed by 122, so that it is retracted into the pressing column 122, and the ring rod and the straight rod can be separated, thereby realizing quick disassembly and assembly and increasing convenience.

[0026] A tension screw rod 2 is fixedly installed between the two straight rods.

[0027] In this embodiment, the tension screw rods 2 are provided to increase the installation strength of the pier column fixing frame 1 and improve the stability.

[0028] Working principle: The walking trolley 5 moves at a constant speed on the walking track 3, and water is transported through the water inlet pipe 8. After passing through the connecting seat pipe 9, the water outlet pipe 6 sprays water onto the pier body through the water outlet nozzle 7 for maintenance, thereby achieving 360-degree maintenance of the bridge pier and ensuring the quality of the pier body. The water outlet nozzle 7 is close to the pier body 100, which can reduce the waste of water resources and is more convenient to use. In addition, the pier column fixing frame 1 can be quickly disassembled and assembled. While the equipment has a low cost, it can also be recycled, further reducing the cost of use.
