Description

Technical Field

[0001] This utility model relates to the field of spray curing technology for cast-in-place beams, and more specifically, to a spray curing device for cast-in-place beams. Background Technology

[0002] Cast-in-place beams are a bridge construction technique characterized by the direct pouring of concrete into prefabricated formwork on-site to form the main structure of the bridge. Unlike precast beams, cast-in-place beams do not require factory prefabrication and subsequent transportation to the site for installation; instead, they are poured and shaped directly on-site. After pouring, cast-in-place beams require spray curing.

[0003] A search revealed that utility model patent CN219547584U discloses a spray curing device for cast-in-place bridge beams, comprising a central track, a track trolley, a water tank, a nozzle bracket, and spray heads. The central track is located at the top center of the cast-in-place beam, and the track trolley is mounted on the central track and can move back and forth along it. Spray heads are respectively installed above and on the outer side of the cast-in-place beam. The nozzle bracket is mounted on the track trolley and fixes each spray head. The outlet of the water tank is connected to a water pump, and the outlet of the water pump is connected to each spray head through a pipe. By building a track on the cast-in-place beam and using the reciprocating motion of the track trolley to drive the reciprocating spraying of water from the spray heads, manpower is effectively saved. Multiple spray heads are provided to provide more comprehensive coverage of the surface of the cast-in-place beam, reducing the generation of spray dead zones and avoiding the problem of spray dead zones caused by water pressure loss of the spray heads.

[0004] However, the aforementioned patents still have the following shortcomings: the lengths of the cast-in-place beams vary, making it inconvenient to adjust the length of the central rail when using an I-beam as the central track; additionally, the widths of the cast-in-place beams also vary, making it inconvenient to adjust the length of the crossbeams above the beams, thus hindering the application of spray curing to cast-in-place beams of different widths. Therefore, we propose a spray curing device for cast-in-place beams. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a spray curing device for cast-in-place beams.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A spray curing device for cast-in-place beams includes a cast-in-place beam body with two track mechanisms. A movable water tank is placed on each track mechanism. Each track mechanism includes multiple intermediate movable boxes mounted on the top surface of the cast-in-place beam body, with each pair of adjacent intermediate movable boxes fitting together. Side movable boxes are mounted at the ends of the two intermediate movable boxes and on the top surface of the cast-in-place beam body. A spraying mechanism is provided on the side of each movable water tank. Four support seats are fixedly connected to the bottom surface of the movable water tank. Rollers are rotatably connected to the outer sides of the bottom ends of the four support seats, and the rollers are placed inside the side movable boxes.

[0009] As a preferred embodiment of this utility model, a battery is provided on the side of the mobile water tank, and a control panel is fixedly installed on the side of the mobile water tank.

[0010] As a preferred embodiment of this utility model, a threaded plug is threadedly installed on the top surface of the mobile water tank.

[0011] In a preferred embodiment of this utility model, the two sides of the inner cavities of the central moving box and the side moving box are flush, and the width of the roller is equal to the width of the inner cavities of the central moving box and the side moving box.

[0012] As a preferred embodiment of this utility model, both the central movable box and the side movable box are provided with mounting holes.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, the middle moving box and the side moving box can be installed on the cast-in-place beam by the cooperation of the mounting holes and screws. Two track mechanisms are formed by multiple middle moving boxes and four side moving boxes so that the moving water tank can be supported by the two track mechanisms. The rollers under the moving water tank can roll on the two track mechanisms. At the same time, the length of the track mechanism can be adjusted according to the length of the cast-in-place beam, so as to ensure that the moving water tank can be moved from one end of the cast-in-place beam to the other end, thereby ensuring that the spraying mechanism on the moving water tank can spray the cast-in-place beam completely.

[0015] (2) In this utility model, the distance between the mounting base, multiple moving frames and moving blocks can be adjusted by the cooperation of multiple electric push rods, so that the two vertical pipes can be moved to both sides of the cast-in-place beam. At the same time, the moving pipes on the sides of the multiple moving frames are evenly distributed on both sides of the top surface of the cast-in-place beam. The water in the inner cavity of the moving water tank is pumped to the inner cavity of the main horizontal pipe, the hose, the moving pipe and the vertical pipe by the water pump. The water in the main horizontal pipe, the moving pipe and the vertical pipe is sprayed from multiple nozzles to the top and sides of the cast-in-place beam to spray and cure the cast-in-place beam. At the same time, the width of the spray curing device can be adjusted according to the width of the cast-in-place beam to adapt to spray curing of cast-in-place beams of different widths, thereby improving the practicality of the cast-in-place beam spray curing device.

[0032] For details, please refer to Figure 3 and Figure 4 The top surface of the mobile water tank 3 is threaded with a threaded plug 28.

[0033] In this embodiment, water is added to the inner cavity of the movable water tank 3 by removing the threaded plug 28.

[0034] For details, please refer to Figure 2 and Figure 3The inner sides of the central moving box 5 and the side moving box 6 are flush, and the width of the roller 9 is equal to the width of the inner cavities of the central moving box 5 and the side moving box 6.

[0035] In this embodiment, the roller 9 is ensured to roll smoothly within the inner cavities of the central moving box 5 and the side moving box 6, while also ensuring the stability of the roller 9 within the inner cavities of the central moving box 5 and the side moving box 6.

[0036] For details, please refer to Figure 2 Both the central movable box 5 and the side movable box 6 are provided with mounting holes 7.

[0037] In this embodiment, the central moving box 5 and the side moving box 6 are installed on the cast-in-place beam 1 by means of mounting holes 7 and screws, so that two track mechanisms 2 are formed by multiple central moving boxes 5 and four side moving boxes 6.

[0038] Working principle: In use, firstly, multiple central movable boxes 5 and four side movable boxes 6 are fixed to the top surface of the cast-in-place beam 1 by screws and mounting holes 7, so that the multiple central movable boxes 5 and four side movable boxes 6 are combined into two track mechanisms 2. Then, the rollers 9 below the movable water tank 3 are placed into the inner cavity of the central movable box 5 or the side movable box 6 on the two track mechanisms 2. Then, multiple electric push rods 24 are activated to drive multiple movable frames 17 and two movable blocks 18 away from each other, so that the two movable blocks 18 move to both sides of the cast-in-place beam 1. At this time, the two vertical pipes 22 are located on both sides of the cast-in-place beam 1, and the movable pipes 21 on the sides of the multiple movable frames 17 are evenly distributed on the top of the cast-in-place beam 1. Then, the dual-axis motor 10 is activated to drive the two rollers 9 to rotate, so that the rollers 9 move in the inner cavity of the central movable box 5 and the side movable box 6, thereby driving the movable water tank 3 and the spraying mechanism 4 to move synchronously. When one side of the movable water tank 3 is L-shaped When the contact sensor 12 on the frame 11 contacts the end face of the inner cavity of the moving box 6 on one side of the track mechanism 2, the dual-axis motor 10 drives the roller 9 to reverse, so that the moving water tank 3 moves in the opposite direction. When the contact sensor 12 on the L-shaped frame 11 on the other side of the moving water tank 3 contacts the end face of the inner cavity of the moving box 6 on the other side of the track mechanism 2, the dual-axis motor 10 is started again to drive the roller 9 to reverse. In this way, the moving water tank 3 moves back and forth on the cast-in-place beam 1. Finally, during the movement of the moving water tank 3, the water pump 13 is started to generate suction in the water pumping pipe 15. The suction in the water pumping pipe 15 is used to pump the water in the inner cavity of the moving water tank 3 to the inner cavity of the main horizontal pipe 16, so that the water in the inner cavity of the main horizontal pipe 16 enters the inner cavity of the hose 25, the moving pipe 21 and the vertical pipe 22, and the water in the inner cavity of the main horizontal pipe 16, the moving pipe 21 and the vertical pipe 22 is sprayed out from multiple nozzles 23 to spray and cure the cast-in-place beam 1.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
