Description

Technical Field

[0001] This utility model relates to the field of concrete curing equipment technology, and in particular to a concrete curing spray device. Background Technology

[0002] Concrete curing is crucial, and its core lies in maintaining a continuously moist surface to prevent problems such as plastic shrinkage cracks and hindered strength development caused by excessive moisture evaporation. Traditional curing methods mainly include covering with water-retaining materials such as straw mats or burlap sacks and manually sprinkling water, or laying plastic film to seal and retain moisture. Manual sprinkling is labor-intensive, inefficient, and difficult to control the amount of water used, and it is hard to ensure uniformity, especially in hot and windy weather. While covering with plastic film can retain moisture, it is easily torn by the wind, and the appearance quality may be affected by excessively high temperatures under the film or adhesion to the concrete surface.

[0003] Currently, the two main methods are: First, a fixed sprinkler system: fixed pipes and sprinklers are installed above or around the maintenance area. This method has limited coverage, with areas near the sprinklers being too wet and areas further away potentially lacking sufficient humidity, resulting in poor uniformity. Second, a simple mobile spray boom: multiple sprinklers are mounted on a long boom, which is manually operated or supported by a simple bracket for mobile spraying. While this is an improvement over purely manual watering, it still requires manual operation, has low automation, and the spray path and uniformity depend on the operator's experience, resulting in limited efficiency gains. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete curing spray device that can evenly and effectively cover the curing area while improving spraying efficiency.

[0005] According to an embodiment of the present invention, a concrete curing spray device includes:

[0006] The ring guide rail mechanism includes a ring base laid on the periphery of the concrete area to be cured and a guide rail unit detachably connected to the ring base.

[0007] The walking mechanism includes a walking base mounted on the guide rail unit and guide and limiting components disposed on both sides of the walking base and cooperating with the guide rail unit.

[0008] A rotary spraying mechanism, comprising a lifting assembly mounted on the walking base, a rotary spray arm that is driven vertically by the lifting assembly and can rotate around a vertical axis, and a plurality of adjustable spraying units mounted on the rotary spray arm.

[0009] Preferably, the guide rail unit has an upper traveling surface at the top and guide surfaces on both sides that are inclined. The guide limiting component cooperates with the guide surfaces. The upper traveling surface is provided with a traveling groove, and the bottom of the traveling base is provided with a drive wheel located in the traveling groove.

[0010] More preferably, the bottom of the walking base is provided with a sliding groove that slides with the guide rail unit, and two drive wheels are provided and located in the sliding groove. The drive wheels support the walking base so that it does not contact the guide rail unit.

[0011] More preferably, the guide limiting component includes a bidirectional telescopic member disposed within the walking base. The bidirectional telescopic member has two coaxial and horizontal telescopic arms. The telescopic arms extend to the outside of the walking base and are connected to a movable frame. The movable frame is provided with adjustable abutment rollers that can cooperate with the guide surface.

[0012] More preferably, the adjustable abutment roller includes an adjusting arm rotatably connected to the movable frame and a servo telescopic rod rotatably mounted on the movable frame. The adjusting arm has a free roller near the guide surface, and the other end is rotatably connected to the servo telescopic rod.

[0013] More preferably, the rotation center of the rotating spray arm is located at its geometric midpoint, and the plurality of adjustable spray units are symmetrically distributed on both sides of the rotation center along the length direction of the rotating spray arm.

[0014] In a further preferred embodiment, the adjustable spray unit includes a mounting base fixed on the rotating spray arm, a universal joint connected to the mounting base at one end via a ball joint, and a spray nozzle mounted at the other end of the universal joint.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This application utilizes a detachable, closed-loop track, which can be laid closely to the outer boundary of concrete structures, completely eliminating blind spots in curing and achieving all-round, dead-angle-free coverage. The detachable design greatly improves the flexibility of on-site deployment and adaptability to different projects;

[0017] The rotating spray arm combined with the circular track movement achieves two degrees of freedom of motion, making the spray head coverage trajectory a complex spiral or grid pattern, which greatly improves the uniformity of spraying.

[0018] The adjustable spray unit allows for real-time manual fine-tuning of the nozzle angle according to the contours of the concrete structure, ensuring that the mist accurately covers the target surface and avoids spraying into non-target areas or missing corners; the lifting column makes the spray height adjustable to adapt to concrete surfaces of different heights or with local protrusions.
