Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a spraying maintenance device. Background Art

[0002] After the box beam is poured, it needs to be sprayed for maintenance. A beam yard uses an automatic spray system for maintenance, and an automatic swing sprinkler is fixed on the stone pier for use. Figure 1 As shown. There are many small holes on the nozzle 1 of this automatic swing sprinkler. The nozzle 1 is rotatably connected to the support frame of the automatic swing sprinkler. Combined with the structural characteristics of the nozzle 1 itself, it can realize automatic swing spraying under the action of water flow. The whole set of equipment has a high degree of automation and can meet the spraying maintenance effect. However, due to water quality problems and the influence of the on-site environment, the nozzle 1 on the automatic swing sprinkler will be blocked and the nozzle 1 will not rotate after long-term use, causing leakage in the spraying maintenance area of ​​the beam body, resulting in poor box beam maintenance effect. In this beam yard, the average replacement cycle of the automatic swing sprinkler is 40 pieces, and it needs to be replaced 25 times, resulting in a high cost for replacing the automatic swing sprinkler. Moreover, the site has high requirements for the spraying effect, and it is necessary to check frequently during normal use, which makes maintenance time-consuming and labor-intensive.

[0003] In addition, in order to solve the water quality problem, if tap water is used, the cost is high. If a water purifier is purchased, it costs about 100,000 yuan per unit, and the effect is not ideal. Therefore, it is urgent to study and improve the above production and construction problems.

The water pipe support plate 171 is provided with a protrusion forming a groove on the left and right sides of the main water pipe 12 for placing the main water pipe 12. Figure 4As shown, the water pipe buckle 172 is an arc-shaped plate protruding upward, and the lower part of the arc-shaped plate is used to limit the main water pipe 12. One end of the arc-shaped plate is hinged on one of the left and right side protrusions, and the other end of the arc-shaped plate is provided with a U-shaped opening, and the other of the left and right side protrusions is provided with a stud. After the arc-shaped plate rotates around its own hinge axis, it can be clamped on the stud through the U-shaped opening, and the water pipe buckle 172 can be fixed by tightening the nut on the stud, thereby fixing the main water pipe 12.

[0031] Embodiment 6 is different from Embodiment 1 in that Figure 2 As shown, the filter box 14 includes a filter box frame 141 in a cubic shape, and a double-layer filter screen 142 fixed on the periphery and bottom of the filter box frame 141. That is, a plurality of steel materials are welded into a cubic shape, and each face of the cubic shape is open. Then, the double-layer filter screen 142 is coated on the periphery and bottom of the cubic filter box frame 141. In this embodiment, the double-layer filter screen 142 is formed by stacking a steel mesh and a nylon mesh to improve the filtering effect.

[0032] Embodiment 7 is different from Embodiment 1 in that Figure 2 and Figure 5 As shown, the mounting tube 2 is coaxially provided with a gear 5, and the swing driving mechanism includes a rack 8 meshing with the gear 5 and a driving assembly for driving the rack 8 to move; a limit support 10 is provided in cooperation with the rack 8, and the rack 8 is slidably arranged on the limit support 10, and the sliding direction is perpendicular to the axis of the mounting tube 2. The sliding of the rack 8 driven by the driving assembly drives the rotation of the gear 5, thereby driving the rotation of the mounting tube 2, so that the sprinkler 1 thereon performs swing spraying, thereby improving the area and efficiency of spraying maintenance.

[0033] Furthermore, if Figure 3 As shown, the driving assembly includes a reciprocating swing motor, and a swing push rod 9 is hinged between the output end of the reciprocating swing motor and the end of the rack 8 to push the rack 8 to slide. The output shaft of the reciprocating swing motor is provided with a swing rod. One end of the swing push rod 9 is hinged to the swing rod, and the other end is hinged to the end of the rack 8.

[0034] Embodiment 8 is different from Embodiment 7 in that Figure 2 and Figure 5As shown, the limit support 10 includes two parallel and spaced vertical support plates and pillars arranged at the lower ends of the vertical support plates, and a horizontal support plate is connected between the pillars to connect and fix the two vertical support plates. A horizontal support block is arranged between the two vertical support plates, and the rack 8 is slidably arranged on the support block and is limited in sliding direction by the two vertical support blocks, so that the rack 8 can only slide linearly in the horizontal direction. In addition, the mounting tube 2 passes through the vertical support plate, and the mounting tube 2 is rotatably connected to the vertical support plate. Through the connection between the mounting tube 2 and the vertical support plate, the limit support 10 and the mounting tube 2 are more closely matched, and the position of the rack 8 limited thereon and the gear is more accurate.

The reciprocating swing motor of the driving assembly is fixed on the movable support plate 113. Pillars are also provided below the two vertical adjustable support plates, and a horizontal support plate is connected between the pillars to connect and fix the two vertical adjustable support plates. The movable support plate 113 is movably connected between the two vertical adjustable support plates, so that the position of the reciprocating swing motor is adjustable. By adjusting the position of the compound swing motor, the position of the compound swing motor relative to the slide bar is changed, thereby changing the sliding track length of the slide bar, thereby changing the rotation angle of the mounting tube, so that the shaking angle of the nozzle 1 is adjustable. In addition, the angle adjustment function of the reciprocating swing motor increases the adjustable range of the shaking angle of the nozzle 1.

[0037] Furthermore, one end of the movable support plate 113 is rotatably connected to one end of the vertically adjustable support plate through 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 through a screw rod 112. A circular arc chute 113 is provided at the corresponding position of the adjustable support plate. The circular arc chute 113 is a circular arc groove with the axis of the rotating rod as the center of the circle, so that the movable support plate 113 can adjust the angle around the axis of the rotating rod, thereby changing the position of the compound swing motor relative to the rack. A nut is tightened on the screw rod 112 to fix the adjusted movable support plate 113. In this embodiment, the rotating rod also uses a screw to tighten the nut to make the movable support plate 113 more stable.

[0038] Embodiment 10 is different from Embodiment 9 in that Figure 5As shown, the position-limiting support 10 and the angle-adjustable support 11 are both arranged on a moving trolley, so that the swing driving mechanism moves synchronously with the corresponding mounting pipe 2 .

[0039] Embodiment 11 is different from Embodiment 1 in that Figure 2 As shown, the mounting pipe 2 includes a plurality of mounting pipe segments connected in sequence. In this embodiment, at least one movable support mechanism is provided under each mounting pipe segment. After the mounting pipe segment is moved to the desired position by the movable support mechanism, the adjacent mounting pipe segments are connected by inserting the butt-connecting pipe 16, that is, the two ends of the butt-connecting pipe 16 having a diameter smaller than that of the mounting pipe 2 are respectively inserted into the adjacent mounting pipe segments, so that the adjacent mounting pipe segments are butted, and then the mounting pipe segments are fixedly connected to the butt-connecting pipe 16 by passing bolts through the butt-connecting pipe 16 and the mounting pipe segments. In addition, the outer wall of the butt-connecting pipe 16 fits with the inner wall of the mounting pipe segment to ensure the concentricity of the adjacent mounting pipe segments.
