Description

Technical Field

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

[0002] After the box girder is poured, it needs to be cured by spraying. A certain beam yard uses an automatic sprinkler system for curing, employing automatic swing sprinklers fixed to the stone piers. Figure 1 As shown, the nozzle 1 of this type of automatic oscillating sprinkler is rotatably connected to the support frame of the nozzle. Combined with the structural features of nozzle 1, it can achieve automatic oscillating spraying under the action of water flow. The entire system has a high degree of automation and good visual effect. However, due to water quality issues and the influence of the site environment, nozzle 1 on the automatic oscillating sprinkler may stop rotating after prolonged use, causing missed spraying in the beam maintenance area, resulting in poor maintenance of the box girder. The automatic oscillating sprinkler has an average replacement cycle of 40 nozzles, requiring replacement 25 times. Replacing the automatic oscillating sprinkler is costly, routine maintenance is time-consuming and labor-intensive, and routine inspections require high spraying effectiveness. This research is based on these pressing production problems. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model proposes a box girder curing spraying device to solve the problem that in the existing automatic spraying system used in beam yards, the spray nozzles stop rotating after prolonged use, resulting in missed spraying in the beam body curing area and thus poor box girder curing effect.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A box girder maintenance spraying device includes a support mechanism, an installation pipe rotatably mounted on the support mechanism, and a nozzle connected to the installation pipe. A swing drive mechanism, in conjunction with the installation pipe, drives the rotation of the installation pipe, thereby causing the nozzle to swing and spray. This invention replaces water-driven swing spraying by fixing the nozzle to the installation pipe and using a motor to drive the rotation of the installation pipe, thus causing the nozzle to swing and spray within a certain range. This reduces the area of ​​missed spraying caused by water-driven mis-rotation, achieving the desired spraying maintenance effect. This invention also allows for the reuse of discarded automatic swing sprinklers or their nozzles by fixing them to the installation pipe, reducing the cost of replacing automatic swing sprinklers. Furthermore, the device is durable and less prone to failure.

[0006] Furthermore, the mounting tube is provided with a gear, and the swing drive mechanism includes a rack meshing with the gear and a drive assembly for driving the rack to move; a limiting support is provided in cooperation with the rack, and the rack is slidably disposed on the limiting support, and the sliding direction is perpendicular to the axis of the mounting tube.

[0007] Furthermore, the drive assembly includes a reciprocating rocking motor, and a rocking push rod is hinged between the output end of the reciprocating rocking motor and the end of the rack for pushing the rack to slide.

[0008] Furthermore, the limiting support includes two parallel and spaced vertical support plates and a support leg disposed at the lower end of the vertical support plates; a support block is provided between the two vertical support plates, and the rack is slidably disposed on the support block and its sliding direction is limited by the two vertical support blocks.

[0009] Furthermore, the mounting tube passes through the vertical support plate and is rotatably connected to the vertical support plate.

[0010] Furthermore, the swing drive mechanism also includes a drive component support for supporting the drive component, and the drive component support is an adjustable angle support for adjusting the angle at which the swing drive mechanism drives the mounting tube to rotate.

[0011] Furthermore, the adjustable angle support includes two parallel and spaced vertically adjustable support plates and a movable support plate for supporting the drive assembly, wherein the movable support plate is movably connected between the two vertically adjustable support plates.

[0012] Furthermore, one end of the movable support plate is rotatably connected to one end of the vertically adjustable support plate via a rotating rod, and the other end of the movable support plate is slidably connected to the other end of the vertically adjustable support plate via a screw. The adjustable support plate is provided with an arc-shaped groove for the screw to slide at a corresponding position; a nut is tightened on the screw to fix the movable support plate after adjustment.

[0013] Furthermore, support legs are provided below the two vertically adjustable support plates.

[0014] Furthermore, the support mechanism includes a horizontal support plate and adjustable legs disposed below the horizontal support plate. The horizontal support plate is provided with a bearing seat that rotates with the mounting tube. The adjustable legs are telescopic support fixtures used to adjust the levelness of the mounting tube.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model fixes the nozzle on the mounting pipe and drives the mounting pipe to rotate by a motor, thereby causing the nozzle to swing and spray within a certain range, replacing the water jet-driven swing spraying method. This reduces the area of ​​missed spraying caused by water-driven non-rotation and achieves the spraying maintenance effect.

[0017] 2. This utility model is achieved by setting a reciprocating swing motor, which is connected to a rack through a swing push rod. A gear that meshes with the rack is set on the mounting tube, thereby driving the mounting tube to rotate within a certain angle range through the reciprocating swing motor, which in turn drives the nozzle to swing and spray.

[0018] 3. This utility model can also fix the waste automatic swing sprinkler or the nozzle on the automatic swing sprinkler onto the installation pipe for waste utilization, reducing the cost of replacing the automatic swing sprinkler. Moreover, the device of this utility model is not prone to failure and is durable.

[0019] 4. This utility model uses multiple telescopic supports to support the installation pipe. The telescopic supports adjust the height of the installation pipe to ensure its horizontality, thereby ensuring that the axis of the installation pipe is parallel to the drive shaft of the reciprocating swing motor. This avoids the problem of the nozzle getting stuck and not rotating, thus preventing missed spraying in the beam spraying and curing area. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 2 As shown in Embodiment 1 of this utility model, a box girder maintenance sprinkler device includes a support mechanism, an installation pipe 2 rotatably mounted on the support mechanism, and multiple nozzles 1 connected to the installation pipe 2. The automatic oscillating sprinkler can be directly fixed to the installation pipe 2, or the nozzles 1 of the automatic oscillating sprinkler can be detached and fixed to the installation pipe 2. Furthermore, the fixing method can be binding or using fixing clips 4 to fix the nozzles 1 to the installation pipe 2. One end of each nozzle 1 is connected to a water supply pipe. A main water pipe is located at the bottom of the box girder maintenance sprinkler device and connected to each water supply pipe for water supply.

[0028] Among them, the structure of the fixing buckle 4, such as Figure 4 As shown. The fixing buckle 4 includes two left and right double semi-ring structures. Each double semi-ring structure includes a larger lower semi-ring and a smaller semi-ring connected to the top of the larger semi-ring. The axes of the larger and smaller semi-rings are parallel. When the two double semi-ring structures are closed, the two larger semi-rings are fixed to the mounting tube 2, and the space between the two smaller semi-rings is used to fix the end of the nozzle 1. The lower ends of the two double semi-ring structures are hinged together, and each upper end has a connecting plate with a perforation or slot. The two connecting plates are parallel and opposite to each other. By inserting bolts into the perforations or slots and tightening them with nuts, the mounting tube and the nozzle can be fixed. The lower ends of the two double semi-ring structures have staggered hinged parts, and the hinged parts of the two double semi-ring structures have aligned perforations for inserting hinge shafts. The axis of the perforations is parallel to the axis of the larger and smaller semi-rings, so that the two double semi-ring structures are hinged together.

[0029] Furthermore, a swing drive mechanism is provided in conjunction with the mounting pipe 2 to drive the rotation of the mounting pipe 2, thereby driving the spray head 1 to swing and spray. This realizes the swing spraying of the electrically driven spray head 1, reducing the missed spray area caused by the water-driven non-rotation and meeting the requirements of spray maintenance.

[0030] Example 2 differs from Example 1 in that, as Figure 2 and Figure 3 As shown, a gear 5 is coaxially mounted on the mounting pipe 2. The swing drive mechanism includes a rack 8 meshing with the gear 5 and a drive assembly for driving the rack 8 to move. A limiting support 10 is provided in cooperation with the rack 8, and the rack 8 is slidably mounted on the limiting support 10, with the sliding direction perpendicular to the axis of the mounting pipe 2. The sliding of the rack 8 driven by the drive assembly drives the rotation of the gear 5, thereby driving the mounting pipe 2 to rotate, causing the nozzle 1 on it to swing and spray, improving the area and efficiency of spray maintenance.

[0031] Furthermore, such as Figure 3As shown, the drive assembly includes a reciprocating rocking motor, and a rocking push rod 9 is hinged between the output end of the reciprocating rocking motor and the end of the rack 8 for pushing the rack 8 to slide. The output shaft of the reciprocating rocking motor has a built-in rocker arm. One end of the rocking push rod 9 is hinged to the rocker arm, and the other end is hinged to the end of the rack 8.

[0032] Example 3 differs from Example 2 in that, as Figure 2 and Figure 3 As shown, the limiting support 10 includes two parallel and spaced-apart vertical support plates and a leg disposed at the lower end of the vertical support plates. A horizontal support plate connects the two vertical support plates and fixes them together. A horizontal support block is provided between the middle of the two vertical support plates. The rack 8 is slidably disposed on the support block and its sliding direction is limited by the two vertical support blocks, so that the rack 8 can only slide in a straight line in the horizontal direction.

[0033] Example 4 differs from Example 3 in that, as Figure 3 As shown, the mounting tube 2 passes through the vertical support plate and is rotatably connected to the vertical support plate. The connection between the mounting tube 2 and the vertical support plate makes the limiting support 10 and the mounting tube 2 fit more tightly, and the position of the rack 8 on it that engages with the gear is more accurate.

[0034] In a preferred embodiment, the mounting tube 2 is rotatably connected to the vertical support plate via a bearing.

[0035] Example 5 differs from Example 2 in that, as Figure 3 As shown, the swing drive mechanism also includes a drive component support for supporting the drive component. The drive component support is an adjustable angle support 11 for adjusting the angle of rotation of the drive mounting tube 2 of the swing drive mechanism.

[0036] Specifically, the adjustable angle support 11 includes two parallel and spaced-apart vertically adjustable support plates and a movable support plate 113 for supporting the drive assembly. The reciprocating swing motor of the drive assembly is fixed to the movable support plate 113. Legs are provided below the two vertically adjustable support plates, and a horizontal support plate connects and fixes the two vertically adjustable support plates together. The movable support plate 113 is movably connected between the two vertically adjustable support plates, making the position of the reciprocating swing motor adjustable. By adjusting the position of the reciprocating swing motor, the position of the reciprocating swing motor relative to the slide bar changes, thereby changing the sliding trajectory length of the slide bar, and thus changing the rotation angle of the mounting tube, making the swing angle of the nozzle 1 adjustable. Combined with the angle adjustment function of the reciprocating swing motor, the adjustable range of the swing angle of the nozzle 1 is increased.

[0037] Furthermore, one end of the movable support plate 113 is rotatably connected to one end of the vertically adjustable support plate via a rotating rod, and the other end of the movable support plate 113 is slidably connected to the other end of the vertically adjustable support plate via a screw 112. The adjustable support plate has an arc-shaped groove 113 at a corresponding position for the screw 112 to slide in. The arc-shaped groove 113 is an arc groove centered on the axis of the rotating rod, allowing the movable support plate 113 to adjust its angle around the axis of the rotating rod, thereby changing the position of the compound rocking motor relative to the rack. A nut is tightened on the screw 112 to fix the adjusted movable support plate 113. In this embodiment, the rotating rod is also tightened with a screw and nut to make the movable support plate 113 more stable.

[0038] Example 6 differs from Example 1 in that, as Figure 2 As shown, the support mechanism includes a horizontal support plate and adjustable legs disposed below the horizontal support plate. The horizontal support plate is provided with a bearing seat that rotatably engages with the mounting tube 2, and the mounting tube 2 is rotatably disposed in the bearing seat via the bearing. The adjustable legs are telescopic support fixtures 6 used to adjust the levelness of the mounting tube 2. This telescopic support fixture 6 is a telescopic support fixture in the prior art.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
