Description

Technical Field

[0001] The utility model belongs to the field of building construction, and specifically relates to a concrete maintenance spraying device. Background Art

[0002] After the concrete structure is cast, it needs to be sprayed and cured to enhance the hydration process of the concrete and ensure the construction quality. Currently, when concrete is maintained and cured, water is sprayed onto the concrete surface through a spray device, which is also one of the most commonly used concrete curing methods on the construction site.

[0003] For example, patent CN202210676337.9 discloses a concrete maintenance device for construction. In order to expand the spraying range, the nozzle is driven to swing up and down and left and right through a driving mechanism, and a large range of spraying maintenance is achieved through the swinging of the nozzle. To achieve the up and down and left and right swinging of the nozzle, it is necessary to design a complex driving mechanism, which leads to a complex overall structure of the device. After the design of the driving mechanism is completed, the swing range of the nozzle is usually controlled to be fixed, and when a small range of spraying is required, it cannot meet the spraying requirements. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a concrete maintenance spraying device to solve the problem that the spraying device in the prior art cannot meet the spraying maintenance needs of different ranges.

[0005] According to the embodiment of the utility model, the utility model adopts the following technical solution:

[0006] A concrete maintenance spray device comprises a moving mechanism and a spray mechanism and an adjusting mechanism installed on the moving mechanism. The spray mechanism is used for spraying and maintaining the concrete structure. The spray mechanism comprises a water tank, a spray pipe connected to the water tank, and a nozzle connected to the end of the spray pipe. The moving mechanism is used to drive the spray mechanism and the adjusting mechanism to move. There are multiple nozzles, and the openings of the multiple nozzles are in different directions. The adjusting mechanism comprises an angle adjustment component for adjusting the spray angle of the nozzle and a range adjustment component for adjusting the spray range of the nozzle. The angle adjustment component comprises a clamping ring fixed on the spray pipe and an angle driving member for driving the clamping ring to rotate. The range adjustment component comprises an adjustment plate movably connected to the nozzle opening and used to adjust the opening of the nozzle opening, and a range driving member for driving the adjustment plate to move.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The water in the water tank is sprayed onto the concrete surface through a nozzle. A plurality of nozzles are provided, and the openings of the plurality of nozzles are in different directions, thereby expanding the spraying range that the nozzles can cover. At the same time, a moving mechanism drives the spraying mechanism and the adjusting mechanism to move, thereby controlling the spraying path to meet different spraying needs. The spraying range is expanded by the design of multiple nozzles, and the structure is simple.

[0009] In addition, according to the spraying needs, the angle of the nozzle and the opening of the nozzle can be adjusted through the adjustment mechanism, thereby changing the spraying angle and spraying range to meet the different spraying maintenance needs of concrete. When a small range of spraying is required, it is only necessary to control some nozzles to close, which is convenient to operate.

[0010] Furthermore, the opening of the nozzle is in a strip shape, and the cross section of the opening of the nozzle is in an isosceles trapezoid.

[0011] Furthermore, the openings of adjacent spray heads extend toward the spraying direction and have overlapping areas.

[0014] Furthermore, the bracket includes a fixed part fixed on the base and a sliding part slidably connected to the fixed part, and the spray pipe is connected to the sliding part.

DETAILED DESCRIPTION

[0020] The utility model is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0021] like Figure 1 As shown, the concrete maintenance spraying device includes a moving mechanism and a spraying mechanism and an adjusting mechanism installed on the moving mechanism. The spraying mechanism is used to spray the concrete structure for maintenance. The spraying mechanism includes a water tank 3, a spraying pipe 6 connected to the water tank 3, and a nozzle 12 connected to the end of the spraying pipe 6. The water tank 3 is fixed on the moving mechanism. The water tank 3 is used to store water for spraying. In order to facilitate the water in the water tank 3 to be sprayed out from the nozzle 12 through the spraying pipe 6, a water pump can be installed in the water tank 3 or in the middle of the spraying pipe 6 to extract the water in the water tank 3 for spraying.

[0022] Combination Figure 2 As shown, a plurality of nozzles 12 are provided, and the openings of the plurality of nozzles 12 are oriented in different directions, so as to expand the spraying range. Figure 2 As shown in the example, this embodiment discloses 6 spray heads 12 designed in parallel, and the opening direction of each spray head 12 is different, which can cover a semicircular spray range. However, in order to avoid gaps in the spray range between adjacent spray heads 12, the openings of adjacent spray heads 12 extend in the spray direction and have overlapping areas. Specifically, the opening of the spray head 12 is in the shape of a strip, and the cross section of the opening of the spray head 12 is in the shape of an isosceles trapezoid. The longer bottom side of the isosceles trapezoid is the free end of the spray head 12, and the opening side sides of adjacent spray heads 12 (i.e., the waist sides of the isosceles trapezoid) are extended to have an intersection.

[0023] In order to facilitate the connection between multiple nozzles 12 and the spray pipe 6, the end of the spray pipe 6 is connected with a connecting pipe head 13. The cross-section of the connecting pipe head 13 is semicircular. Multiple nozzles 12 are evenly distributed along the circumference of the connecting pipe head 13. The connecting pipe head 13 is provided with a connecting hole 15 for connecting with the nozzle 12. In the actual design process, valves can be installed in the connecting holes 15 to control the number of nozzles 12 to be opened.

[0024] The mobile mechanism is used to drive the spray mechanism and the adjustment mechanism to move. The mobile mechanism includes a base 1, a bracket 7 installed on the base 1, and a plurality of universal wheels 2 installed at the lower end of the base 1. The universal wheels 2 are universal wheels 2 with foot brakes in the prior art. The water tank 3 is fixed on the base 1, and the spray pipe 6 is installed on the bracket 7. Specifically, a mounting ring 8 is fixed on the upper end of the bracket 7, and the spray pipe 6 passes through the mounting ring 8. The mounting ring 8 has a certain limiting effect on the spray pipe 6. During use, in order to facilitate the movement of the base 1, a handle can be fixed on the base 1, so that the staff can push the base 1 to move by the handle, thereby driving the water tank 3 and the spray pipe 6 to move, so as to control the spray path.

[0025] The adjustment mechanism includes an angle adjustment component for adjusting the spray angle of the nozzle 12 and a range adjustment component for adjusting the spray range of the nozzle 12. The angle adjustment component includes a clamping ring 10 fixed on the spray pipe 6 and an angle driving member for driving the clamping ring 10 to rotate. Specifically, in this embodiment, the clamping ring 10 is rotatably connected to the bracket 7. Specifically, a mounting plate 9 is fixed on the mounting ring 8. The angle driving member includes a motor fixed on the mounting plate 9. A rotating rod 11 is fixed to the side wall of the clamping ring 10. The output shaft of the motor is fixed to the rotating rod 11. The rotation axis of the rotating rod 11 is perpendicular to the axis of the clamping ring 10. Figure 1 Taking the direction shown in as an example, the clamp ring 10 can drive the spray pipe 6 to swing in the up and down directions.

[0026] The range adjustment component includes an adjustment plate 14 movably connected to the opening of the nozzle 12 and used to adjust the opening of the nozzle 12, and a range driving member for driving the adjustment plate 14 to move. Specifically, in this embodiment, the adjustment plate 14 is provided with two pieces and is respectively hinged to the inner walls on both sides of the opening of the nozzle 12. Specifically, a hinge shaft is fixed to the end of the adjustment plate 14, and the hinge shaft is rotatably connected to the inner wall of the nozzle 12. The range driving member includes a motor fixed to the outside of the nozzle 12, and the output shaft of the motor extends through the nozzle 12 and is fixed to the hinge shaft. By rotating the adjustment plate 14, the angle between the adjustment plate 14 and the inner wall of the nozzle 12 can be controlled to control the opening of the nozzle 12. That is, in actual use, the adjustment plate 14 is actually used as the inner wall of the nozzle 12, and water is sprayed out from between the two adjustment plates 14. In addition, through the design of the two adjustment plates 14, the angles of the two adjustment plates 14 can be controlled at the same time, so that the opening of the nozzle 12 can be evenly adjusted.

[0027] During specific use, the base 1 is pushed to move, and the water in the water tank 3 is sprayed onto the surface of the concrete structure through the nozzle 12. The angle of the nozzle 12 and the opening degree of the nozzle 12 can be adjusted as needed to meet different spraying and maintenance needs of the concrete. Through the design of multiple nozzles 12, the opening degree of each nozzle 12 can also be controlled to be different as needed. For example, the nozzles 12 located on both sides of the connecting pipe head 13 mainly spray to the side. The nozzle 12 can be controlled to be closed or only open a smaller opening through the adjustment plate 14 according to actual needs. When the ends of the two adjustment plates 14 are against each other, the opening of the nozzle 12 can be closed to a certain extent.

[0028] In another embodiment of the utility model, the bracket 7 includes a fixed portion 16 fixed to the base 1 and a sliding portion 17 slidably connected to the fixed portion 16. During actual use, the bracket 7 can use the electric telescopic plate in the prior art, or other structures with telescopic functions, as long as the sliding portion 17 can remain motionless after sliding to the specified position. For example, a cylinder for driving the sliding portion 17 to slide can be fixed on the base 1. The spray pipe 6 is connected to the sliding portion 17, that is, the mounting ring 8 is fixed to the upper end of the sliding portion 17. The clamping ring 10 is installed on the sliding portion 17, and the rotation axis of the clamping ring 10 is perpendicular to the sliding direction of the sliding portion 17. Specifically, a rotating rod 11 is fixed to the side wall of the clamping ring 10. The rotation axis of the clamping ring 10 is actually the rotation axis of the rotating rod 11, and the axis of the clamping ring 10 is perpendicular to the rotation axis of the rotating rod 11. The rotation axis of the rotating rod 11 is perpendicular to the sliding direction of the sliding portion 17, so that Figure 1 Taking the direction shown in as an example, the sliding part 17 slides vertically, and the rotation axis of the rotating rod 11 is in a direction perpendicular to the paper surface, then the clamping ring 10 can drive the spray pipe 6 to swing in the up and down directions.

[0029] In another embodiment of the utility model, a telescopic rod 4 is fixed on the base 1, and the telescopic direction of the telescopic rod 4 is parallel to the sliding direction of the sliding part 17. The telescopic rod 4 can be an electric telescopic rod 4 in the prior art or other rods with telescopic functions. A support ring 5 for supporting the spray pipe 6 is fixed on the telescopic rod 4. When in use, the spray pipe 6 passes through the support ring 5. When the sliding part 17 drives the spray pipe 6 to slide upward, the telescopic rod 4 drives the spray pipe 6 to slide downward, so that the spray pipe 6 has enough length to slide up with the sliding part 17. When the sliding part 17 drives the spray pipe 6 to slide downward, the telescopic rod 4 drives the spray pipe 6 to slide upward to avoid the excess spray pipe 6 from being piled up on the base 1 and being squeezed. The telescopic rod 4 can support the excess spray pipe 6.
