Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, in particular to a concrete high-temperature curing spraying device. Background Technique

[0002] Concrete curing is to artificially create certain humidity and temperature conditions so that the freshly poured concrete can be cured normally or accelerated in its hardening and strength growth. The reason why concrete can gradually harden and increase in strength is the result of the hydration of cement, and the hydration of cement requires certain temperature and humidity conditions.

[0003] It is known that the authorized patent with the application number: CN202322347893.4 discloses a concrete curing device for concrete preparation. The background technology thereof puts forward the problem that "when concrete is continuously in high-temperature operation in the curing chamber, the pressure in the curing chamber is generally relatively high, resulting in difficulty in opening the sealing door". For this reason, the technical solution to solve this problem in this scheme is "including a concrete curing chamber, an air inlet is opened at the top of the concrete curing chamber, a pressure relief box is fixedly connected to the top of the concrete curing chamber, and a pressure measuring and sealing mechanism is arranged inside the pressure relief box" and so on.

[0004] However, it is found in the implementation of the related technology that the above technical solution has the following problems: Although it realizes the pressure relief inside the concrete curing chamber through the provided technical solution and facilitates the opening of the sealing door in the later stage, when it is in use, the position of the spraying plate is fixed and it is inconvenient to move and adjust the spraying, which easily causes a small spraying range of water vapor, thereby reducing the spraying uniformity and the concrete curing effect. Summary of the Utility Model

[0005] The utility model provides a concrete high-temperature curing spraying device, which solves the problems of inconvenient mobile spraying, easy to cause a small spraying range and poor uniformity in the related technology.

[0006] The technical solution of the utility model is as follows: A concrete high-temperature curing spraying device, comprising: a curing chamber body and sliding rails symmetrically and fixedly installed on both sides of the inner wall of the curing chamber body;

At the same time, the motor drives the first synchronous pulley to rotate, and the synchronous belt drives the second synchronous pulley to rotate, so that the reciprocating lead screw rotates to drive the atomizing spray disc to perform reciprocating longitudinal movement and spraying along the surface of the guide rod. At the same time, the reciprocating lead screw rotates to drive the gear to rotate, and under the action of the rack, the movable plate moves horizontally along the slide rail.

[0027] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0028] Please refer to Figure 1 - Figure 4 , a concrete high-temperature curing spraying device provided by the present utility model includes: a curing chamber body 1 and slide rails 2 symmetrically and fixedly installed on both sides of the inner wall of the curing chamber body 1. Among them, a controller is installed on the curing chamber body 1 to facilitate centralized control of the components in the present device;

[0029] A movable plate 3 slidably clamped in the slide rail 2;

[0030] A reciprocating lead screw 4 passing through between the opposite surfaces of the two movable plates 3 and rotatably connected to the movable plates 3. The reciprocating lead screw 4 is rotated by a power mechanism provided on the movable plate 3;

[0031] The atomizing spray plate 5 is threadedly connected to the surface of the reciprocating lead screw 4 through a base block. A water delivery hose 6 with one end extending out of the curing chamber body 1 is fixedly installed at the top of the atomizing spray plate 5. Among them, one end of the water delivery hose 6 extending out of the curing chamber body 1 is connected with a flange for easy connection with an external water supply pipe;

[0032] The rack 7 fixedly installed on the top of the slide rail 2;

[0033] And the gears 8 fixedly connected to both ends of the reciprocating lead screw 4 and meshing with the rack 7.

[0034] The power mechanism includes a first synchronous pulley 9 fixedly installed on the surface of one end of the reciprocating lead screw 4, a motor 10 fixedly installed on the top of one movable plate 3, and a second synchronous pulley 11 fixedly connected to the output end of the motor 10. The second synchronous pulley 11 and the first synchronous pulley 9 are tensioned and meshed through a synchronous belt. Among them, the motor 10 is electrically connected to the controller.

[0035] A guide rod 12 located on one side of the reciprocating lead screw 4 is fixedly installed between the opposite surfaces of the two movable plates 3. The atomizing spray plate 5 is slidably connected to the guide rod 12 through a base block two. Among them, the atomizing spray plate 5 is composed of a spray plate and a plurality of atomizing nozzles installed at its bottom.

[0036] The technical solution provided by this embodiment is as follows: When in use, the concrete is placed in the curing chamber body 1, and then water is input into the water delivery hose 6 through an external water pipe and atomized and sprayed out through the atomizing spray plate 5. At the same time, the motor 10 drives the first synchronous pulley 9 to rotate, and the second synchronous pulley 11 is driven to rotate through the synchronous belt, so that the reciprocating lead screw 4 rotates to drive the atomizing spray plate 5 to perform reciprocating longitudinal movement and spraying along the surface of the guide rod 12. At the same time, the reciprocating lead screw 4 rotates to drive the gear 8 to rotate, and under the action of the rack 7, the movable plate 3 moves horizontally along the slide rail 2. Therefore, the effect of horizontal movement and spraying can be achieved while the atomizing spray plate 5 performs reciprocating longitudinal movement and spraying, ensuring the comprehensiveness of spraying, avoiding the problem of a relatively small fixed spraying position range, and effectively improving the uniformity of concrete spraying and the curing effect.

[0037] Furthermore, a placement rack 13 is provided in the curing chamber body 1, and heating plates 14 are symmetrically and fixedly installed on both sides of the inner wall of the bottom of the curing chamber body 1. Among them, the heating plates 14 are electrically connected to the controller.

[0038] Specifically, by setting the placement rack 13, it is convenient to lay and place multiple concretes. By setting the heating plates 14, the concrete in the curing chamber body 1 can be heated and cured.

[0039] Furthermore, a pressure relief mechanism is provided at the top of the curing chamber body 1;

[0040] The pressure relief mechanism includes a pressure relief pipe 15 fixedly installed at the top of the curing chamber body 1, a pressure relief cover 16 fixedly installed on the surface of the pressure relief pipe 15, a movable rod 17 slidably connected through the top of the pressure relief cover 16, a piston block 18 fixedly connected to the bottom end of the movable rod 17 for blocking the pressure relief pipe 15 and fitting against the inner wall of the pressure relief cover 16, a moving plate 19 sleeved on the surface of the movable rod 17, and a spring 20 sleeved on the surface of the movable rod 17. The two ends of the spring 20 are respectively connected to the piston block 18 and the moving plate 19. Two pressure relief holes are symmetrically formed on the surface of the pressure relief cover 16.

[0041] Specifically, during the heating process of the curing chamber body 1, the air pressure inside it increases. At this time, the air pressure pushes the piston block 18 upward to compress the spring 20, and drives the movable rod 17 upward, so that the pressure relief pipe 15 is opened, and the air pressure enters the pressure relief cover 16 and is discharged through the pressure relief holes, achieving the purpose of relieving the internal pressure of the curing chamber body 1. After the pressure returns to normal, the piston block 18 is driven by the spring 20 to reset and block the pressure relief pipe 15.

[0042] Further, two door bodies are installed on one side surface of the curing chamber body 1 through hinges. Handles are fixedly installed on one side surface of the two door bodies, and observation windows are provided on one side surface of the two door bodies.

[0043] Specifically, by setting the handles, it is convenient to open or close the door bodies, facilitating personnel to enter the inside of the curing chamber body 1. By setting the observation windows, personnel can observe the curing condition of the concrete. Embodiment 2

[0044] Based on Embodiment 1, in this embodiment: One side of the top of the pressure relief cover 16 is threadedly connected through and rotatably connected to an adjusting screw rod 21 of the moving plate 19, and a limiting rod 22 slidably connected to the pressure relief cover 16 is fixedly installed on one side of the top of the moving plate 19.

[0045] The technical solution provided in this embodiment is: By rotating the adjusting screw rod 21, under the action of screw rotation, the adjusting screw rod 21 drives the moving plate 19 to move downward along the surface of the movable rod 17, and drives the limiting rod 22 to slide, so that the moving plate 19 compresses the spring 20, facilitating the purpose of adjusting the tightness of the spring 20, and facilitating personnel to adjust the pressure relief standard according to the required air pressure value inside the curing chamber body 1.

[0046] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
