[0001] This utility model belongs to the field of bridge construction and maintenance technology, and in particular relates to a bridge high pier climbing formwork maintenance device. Background Technology

[0002] In modern bridge construction, high pier construction has become a common type of bridge pier. With technological advancements, spray curing methods for high pier construction have been widely adopted. Spray curing is characterized by flexible installation and ease of use. By converting water jets into spray forms, the contact area between the concrete surface and water is increased. This not only avoids the uneven curing surface and water loss caused by traditional manual watering curing, but also significantly improves water use efficiency.

[0003] A search revealed an existing patent (authorization announcement number: CN222796210U) disclosing a high-pier climbing formwork construction and maintenance device. This device includes a support unit mounted on a climbing formwork frame. The upper and lower sides of the support unit are respectively equipped with a covering unit and a spray nozzle assembly. The climbing formwork frame is detachably mounted on a cured structure, and a structure to be cured is placed on the cured structure. The covering unit includes a mounting frame containing a waterproof cloth, which is detachably attached to the outside of the structure to be cured. The spray nozzle assembly includes a spray nozzle, which sprays water onto the waterproof cloth to complete the curing of the structure to be cured. This invention has a compact structure, is simple to operate, and significantly improves the effectiveness of pier column spray curing, ensuring construction quality.

[0004] However, the above structure still has shortcomings. The position of its nozzle assembly is fixed, making it difficult to spray water continuously and evenly on the work area, which can easily lead to insufficient moisture in the concrete in the area and affect the curing quality.

[0005] Therefore, it is necessary to provide a new bridge high pier climbing formwork maintenance device to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a bridge pier climbing formwork maintenance device that can continuously and uniformly spray water to maintain the working area.

[0007] To solve the above-mentioned technical problems, the bridge high pier climbing formwork maintenance device provided by this utility model includes: a bridge high pier body, a plurality of climbing rails fixedly installed on the bridge high pier body, a climbing formwork body set on two corresponding climbing rails, and a water spraying maintenance mechanism set on the climbing formwork body.

[0008] The water spraying maintenance mechanism includes a fixed frame, which is fixedly installed on the climbing formwork body. A mounting plate is fixedly connected to the top surface of the fixed frame, and a drive motor is fixedly installed on the mounting plate. A lead screw is fixedly connected to the output end of the drive motor. A bottom support plate is fixedly connected to the inner surface of the fixed frame. The bottom end of the lead screw is rotatably connected to the top surface of the bottom support plate. A movable plate is threaded onto the outer wall of the lead screw. Three cross support plates are fixedly connected to one side surface of the movable plate. Water spray pipes are fixedly installed on the corresponding three cross support plates. Multiple atomizing nozzles are threaded onto the water spray pipes, and hoses are fixedly connected to the water spray pipes.

[0009] As a further embodiment of this utility model, a limiting ring is fitted onto the hose, and the other end of the limiting ring is fixedly connected to one side surface of the fixing frame.

[0010] As a further embodiment of this utility model, two T-shaped grooves are provided on the fixed frame, and sliding plates that are adapted to the T-shaped grooves are fixedly connected to both ends of the movable plate.

[0011] As a further embodiment of this utility model, two diagonal braces are fixedly installed on the climbing formwork body, and the two diagonal braces are symmetrically distributed on the climbing formwork body.

[0012] As a further embodiment of this utility model, the inclined support includes two hinge seats, both of which are fixedly installed on the climbing formwork body. Each of the two hinge seats is fixedly connected with a threaded rod, and a threaded sleeve is threaded onto the corresponding two threaded rods.

[0013] As a further embodiment of this utility model, the thread directions of the two corresponding threaded rods are one positive and one negative, and the inner wall shape of the threaded sleeve is adapted to the outer wall shape of the two threaded rods.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 This is a schematic diagram of the overall structure of the bridge high pier climbing formwork maintenance device of this utility model; Figure 2 This is a schematic diagram of the main structure of the bridge high pier climbing formwork maintenance device of this utility model; Figure 3 This is a schematic diagram of the water spraying curing mechanism of the bridge high pier climbing formwork curing device of this utility model; Figure 4 This utility model provides a schematic diagram of the inclined support structure of the bridge pier climbing formwork maintenance device. The bridge pier climbing formwork maintenance device includes: a bridge pier body 1, on which multiple climbing rails 2 are fixedly installed, and climbing formwork bodies 3 are provided on two corresponding climbing rails 2. The climbing formwork bodies 3 are provided with a water spraying maintenance mechanism.

[0024] The water spraying maintenance mechanism includes a fixed frame 4, which is fixedly installed on the climbing formwork body 3. A mounting plate 5 is fixedly connected to the top surface of the fixed frame 4. A drive motor 6 is fixedly installed on the mounting plate 5. A lead screw 7 is fixedly connected to the output end of the drive motor 6. A bottom support plate 8 is fixedly connected to the inner surface of the fixed frame 4. The bottom end of the lead screw 7 is rotatably connected to the top surface of the bottom support plate 8. A movable plate 9 is threaded onto the outer wall of the lead screw 7. Three cross support plates 10 are fixedly connected to one side surface of the movable plate 9. Water spray pipes 11 are fixedly installed on the three corresponding cross support plates 10. Multiple atomizing nozzles 12 are threaded onto the water spray pipes 11. A flexible hose 13 is fixedly connected to the water spray pipes 11.

[0025] like Figure 3 As shown, a limiting ring 14 is fitted on the hose 13, and the other end of the limiting ring 14 is fixedly connected to one side surface of the fixing frame 4.

[0026] By constraining the hose 13 with the limiting ring 14, excessive shaking or tangling of the hose 13 can be avoided when the water spray pipe 11 rises and falls with the moving plate 9, thus ensuring the stability of the water delivery process.

[0027] like Figure 3 As shown, two T-shaped grooves 15 are provided on the fixed frame 4, and sliding plates that are adapted to the T-shaped grooves 15 are fixedly connected to both ends of the movable plate 9.

[0028] The T-shaped slide 15, in conjunction with the sliding plate, provides guidance for the lifting and lowering of the moving plate 9, ensuring that the moving plate 9 moves smoothly along a fixed trajectory under the drive of the lead screw 7, avoiding deviation or jamming, thereby ensuring the positional accuracy of the water spray pipe 11 and the atomizing nozzle 12, and improving the uniformity of the maintenance operation.

[0029] like Figure 1 As shown, two diagonal braces 16 are fixedly installed on the climbing formwork body 3, and the two diagonal braces 16 are symmetrically distributed on the climbing formwork body 3.

[0030] By setting two symmetrically distributed diagonal braces 16 on the climbing formwork body 3, the climbing formwork body 3 is prevented from tilting or deforming due to uneven force during construction or maintenance, thus ensuring construction safety.

[0031] like Figure 4 As shown, the inclined support 16 includes two hinge seats 17, both of which are fixedly installed on the climbing formwork body 3. Both of the hinge seats 17 are fixedly connected with threaded rods 18, and threaded sleeves 19 are threadedly sleeved on the corresponding two threaded rods 18.

[0032] The threaded connection between the threaded rod 18 and the threaded sleeve 19 allows for adjustment of the overall length of the diagonal brace 16, ensuring that the diagonal brace 16 can fit tightly against the force and further improve the support effect.

[0033] like Figure 4 As shown, the thread directions of the two corresponding threaded rods 18 are one positive and one negative, and the inner wall shape of the threaded sleeve 19 is adapted to the outer wall shape of the two threaded rods 18.

[0034] By setting the thread direction of the two threaded rods 18 to be one positive and the other negative, when the threaded sleeve 19 is rotated, the two threaded rods 18 can simultaneously move closer to the inside of the threaded sleeve 19 or extend outward, realizing the rapid adjustment of the length of the diagonal brace 16, which is convenient and efficient to operate.

[0035] The drive motor 6 is model JGB37-520.

[0036] The working principle of the bridge high pier climbing formwork maintenance device provided by this utility model is as follows:

[0037] First step: When using it, first install the climbing formwork body 3 on the climbing rail 2 of the bridge pier body 1. By rotating the threaded sleeve 19, the two threaded rods 18 are synchronously extended and retracted, thereby adjusting the length of the diagonal brace 16. Then connect the hose 13 to the external water source, check the installation and sealing of each atomizing nozzle 12, start the drive motor 6, and the drive motor 6 drives the lead screw 7 to rotate. Under the guidance of the T-shaped slide 15 and the sliding plate, the moving plate 9 moves smoothly up and down along the lead screw 7, and then drives the water spray pipe 11 and the atomizing nozzle 12 to rise and fall synchronously through the cross brace plate 10. During this process, the limiting ring 14 constrains the movement trajectory of the hose 13 with the water spray pipe 11 to prevent the hose 13 from shaking or getting tangled.

[0038] The second step: Then, the external water source supplies water to the spray pipe 11 through the hose 13. The water flows through multiple atomizing nozzles 12 and is atomized and sprayed evenly on the concrete surface of the bridge pier body 1. By controlling the forward and reverse rotation and start and stop of the drive motor 6, the lifting range and stopping position of the atomizing nozzles 12 are adjusted to achieve comprehensive spraying and curing of the concrete of the bridge piers at different heights and in different areas, ensuring that the concrete surface remains continuously moist, thereby completing the curing work.
