Description

Technical Field

[0001] The utility model relates to the technical field of spray devices, in particular to an intelligent spray device for a bridge cap beam. Background Art

[0002] The manufacturing and processing of bridge cap beams for most infrastructure projects are usually completed in a centralized prefabrication yard. The prefabricated bridge cap beams need to be sprayed and maintained on a daily basis to ensure their quality. Mobile automatic spraying devices are usually used for maintenance.

[0003] The existing automatic sprinkler maintenance device for bridge caps is not able to adjust the spraying angle of the mobile automatic sprinkler during use, and cannot effectively adapt to different spraying angles during bridge cap maintenance. A single spraying angle will result in a limited spraying area, poor spraying effect, unsatisfactory local spraying effect, poor maintenance uniformity, and poor use effect, which will affect the quality of the bridge cap and leave quality and safety hazards. In addition, the existing automatic sprinkler device adopts a continuous water discharge method when spraying, and continuous water spraying will easily lead to excessive spraying and serious water waste.

[0004] Based on this, the utility model designs an intelligent spraying device for bridge cap beams to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide an intelligent spraying device for a bridge cap beam to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

A nozzle is fixed to the bottom of the swing arm, which can drive the nozzle to swing. Therefore, when the nozzle is used to spray the bridge cap beam, the spray angle can be adjusted to expand the spray area, thereby avoiding the problem of unsatisfactory local spraying effect.

[0017] In addition, the utility model supplies water to the sprinkler head through a water storage cylinder, and a first one-way valve and a second one-way valve are installed on the water storage cylinder. When the inner rod moves upward, the pressure rod and the piston will be driven upward, thereby reducing the internal pressure of the water storage cylinder and sucking water into the water storage cylinder through the first one-way valve.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figures 1 to 5 As an embodiment of the present utility model, a bridge cap beam intelligent spraying device includes a bridge cap beam 1, a plurality of bridge piers 2 are fixed to the bottom of the bridge cap beam 1, a top beam 3 is overlapped on the top of the bridge cap beam 1, a top frame 4 is fixed on the top beam 3, a cylinder 5 is fixed on the top beam 3, a supporting frame 6 is fixed on the output piston rod of the cylinder 5, a plurality of rotating cylinders 7 distributed at equal intervals are rotatably provided on the top frame 4, and a plurality of inner rods 8 movably inserted in the rotating cylinders 7 are fixed to the bottom of the supporting frame 6;

[0026] The inner rod 8 and the rotating cylinder 7 are connected and matched by a first linkage structure. When the inner rod 8 moves up and down, it drives the rotating cylinder 7 to rotate clockwise or counterclockwise.

[0027] A swing arm 11 is rotatably provided on the top frame 4, and a nozzle 12 is fixed to the bottom of the swing arm 11. The swing arm 11 is connected to the rotating cylinder 7 through a second linkage structure. When the rotating cylinder 7 rotates clockwise or counterclockwise, the swing arm 11 is driven to swing;

[0028] A water storage cylinder 13 is fixed on the top frame 4 and on both sides of the rotating cylinder 7. A pressure rod 14 is movably inserted in the water storage cylinder 13. A piston 15 that is movably connected to the water storage cylinder 13 is fixed at the bottom of the pressure rod 14. A first one-way valve 16 and a second one-way valve 17 are installed on the water storage cylinder 13. The second one-way valve 17 is connected to the nozzle 12 through a hose 18.

[0029] In this embodiment, the starting cylinder 5 can drive the supporting frame 6 to move up and down, and the supporting frame 6 can drive the inner rod 8 to move up and down when moving up and down. When the inner rod 8 moves up and down, it drives the rotating cylinder 7 to rotate clockwise and counterclockwise. When the inner rod 8 moves up, it drives the rotating cylinder 7 to swing in one direction, so that when the rotating cylinder 7 rotates in one direction, it drives the swing arm 11 to rotate. A nozzle 12 is fixed to the bottom of the swing arm 11, which can drive the nozzle 12 to rotate, so that when the nozzle 12 is used to spray the bridge cap beam, the spraying angle can be adjusted to expand the spraying area. When the inner rod 8 moves down, it drives the rotating cylinder 7 to swing in the opposite direction, thereby driving the swing arm 11 to rotate in the opposite direction and drive the nozzle 12 to reset;

[0030] In addition, water is supplied to the nozzle 12 through the water storage cylinder 13. A first one-way valve 16 and a second one-way valve 17 are installed on the water storage cylinder 13. When the inner rod 8 moves upward, the pressure rod 14 and the piston 15 will be driven to move upward, thereby reducing the internal pressure of the water storage cylinder 13 and sucking water into the water storage cylinder 13 through the first one-way valve 16. At this time, the nozzle 12 stops spraying. When the inner rod 8 moves downward, the pressure rod 14 and the piston 15 move downward, and the internal pressure of the water storage cylinder 13 increases, and water is discharged into the hose 18 through the second one-way valve 17, thereby spraying through the nozzle 12. The inner rod 8 moves up and down cyclically, and the water storage cylinder 13 is used to cyclically suck and discharge water, thereby achieving an intermittent spraying effect.

[0031] As a further solution of the present invention, a controller 21 and a temperature and humidity sensor 22 (model: HDC1080DMBR) are fixedly installed on the bridge cap beam 1, and the signal output end of the temperature and humidity sensor 22 is connected to the signal output end of the controller 21, and the signal output end of the controller 21 is connected to the signal input end of the cylinder 5.

[0032] In this embodiment, the ambient temperature and humidity are detected by the temperature and humidity sensor 22. By automatically sensing factors such as the ambient temperature and humidity, when the temperature is high and the air is dry, the controller 21 is used to intelligently control the start and stop of the cylinder 5 for spraying, so as to effectively prevent the concrete from drying out and achieving the effect of intelligent control.

[0033] As a further solution of the present invention, the first linkage structure includes a track groove 19 opened on the inner rod 8 and a ball 20 movably embedded and clamped on the inner wall of the rotating cylinder 7. The ball 20 is movably clamped in the track groove 19 and can roll along the track where the track groove 19 is located.

[0034] In this embodiment, when the inner rod 8 moves up and down, the ball 20 rolls along the track where the track groove 19 is located, driving the driving gear 9 to rotate clockwise or counterclockwise.

[0035] As a further solution of the present invention, the second linkage structure includes a driving gear 9 fixed on the rotating cylinder 7 and a driven gear 10 rotatably arranged on the top frame 4. The driven gear 10 is meshed and connected with the driving gear 9, and one end of the swing arm 11 is fixed on the driven gear 10.

[0036] In this embodiment, the rotation of the rotating cylinder 7 drives the driving gear 9 to rotate, thereby driving the driven gear 10 to rotate, and then driving the swing arm 11 to rotate.

[0037] As a further solution of the present invention, the first one-way valve 16 is connected to an external water source through a pipeline, and the first one-way valve 16 is used to allow water to flow into the water storage cylinder 13 .

[0038] In this embodiment, when the inner rod 8 moves upward, it drives the pressure rod 14 and the piston 15 to move upward, thereby reducing the internal pressure of the water storage cylinder 13 and sucking water into the water storage cylinder 13 through the first one-way valve 16.

[0039] As a further solution of the present invention, the outer diameter of the piston 15 is adapted to the inner diameter of the water storage cylinder 13 , and a sealing ring is fixedly adhered to the outer edge of the piston 15 .

[0040] In this embodiment, the sealing performance of the joint between the piston 15 and the water storage cylinder 13 is increased to prevent air leakage from affecting the water suction and discharge effects.

[0041] The working principle of this utility model is: the temperature and humidity of the surrounding environment are detected by the temperature and humidity sensor 22, and the ambient temperature, humidity and other factors are automatically sensed. When the temperature is high and the air is dry, the controller 21 is used to control the start and stop of the cylinder 5. Starting the cylinder 5 can drive the support frame 6 to move up and down. The support frame 6 can drive the inner rod 8 to move up and down. When the inner rod 8 moves up and down, it will drive the rotating cylinder 7 to rotate clockwise and counterclockwise. When the inner rod 8 moves up, it will drive the rotating cylinder 7 to swing in one direction, so that when the rotating cylinder 7 rotates in one direction, it will drive the swing arm 11 to rotate. A nozzle 12 is fixed at the bottom of the swing arm 11, which can drive the nozzle 12 to rotate, so that when the nozzle 12 is used to spray the bridge cap beam, the spray angle can be adjusted to expand the spraying area. When the inner rod 8 moves down, the rotating cylinder 7 can be driven to rotate in one direction. When the inner rod 8 moves upward, the pressure rod 14 and the piston 15 will be driven upward to reduce the internal pressure of the water storage cylinder 13 and absorb water into the water storage cylinder 13 through the first one-way valve 16. At this time, the nozzle 12 stops spraying. When the inner rod 8 moves downward, the pressure rod 14 and the piston 15 move downward, the internal pressure of the water storage cylinder 13 increases, and water is discharged into the hose 18 through the second one-way valve 17, thereby spraying through the nozzle 12, thereby cyclically moving up and down through the inner rod 8 and cyclically absorbing and discharging water through the water storage cylinder 13, thereby achieving the effect of intermittent spraying.

[0042] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
