DETAILED DESCRIPTION

[0046] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] like Figures 1 to 4 As shown, this embodiment proposes a spray device for bridge maintenance, including: a base 1, the base 1 has a cavity 2 inside; a water pipe 4, which is arranged in the base 1, the water pipe 4 has a water inlet end and a water outlet end, and the water inlet end and the water outlet end are both located outside the base 1; a branch pipe 17, which is arranged on the water pipe 4, the branch pipe 17 is connected to the water pipe 4, and a first valve 8 is arranged on the branch pipe 17; a nozzle 6, which is connected to the branch pipe 17, the nozzle 6 passes through the side wall of the base 1 and is slidably connected to the side wall of the base 1; a first driving mechanism 9, which is arranged in the cavity 2, the first driving mechanism 9 is transmission-connected to the nozzle 6, and the first driving mechanism 9 is used to drive the nozzle 6 to rotate; a second driving mechanism 5, which is arranged in the cavity 2, the second driving mechanism 5 is transmission-connected to the nozzle 6, and the second driving mechanism 5 is used to drive the nozzle 6 to extend out of the side wall of the base 1; a controller, which is arranged in the base 1, and the first valve 8, the first driving mechanism 9 and the second driving mechanism 5 are all electrically connected to the controller.

[0048] In the above scheme, it should be noted first that a water pool is set up in the prefabricated beam yard, and then a water pump is set up. The water pump is connected to the water pipe 4 through an external pipe, and the water inlet end of the water pipe 4 of the spray device is connected to the external pipe. Under the action of the water pump, the water in the water pool will enter the spray device for use by the spray device to maintain the bridge beam 18.

[0049] Secondly, two branch pipes 17 are provided, because it is necessary to spray both side walls of the bridge beam 18 at the same time, and the two branch pipes 17 are arranged symmetrically about the water pipe 4. The first valve 8 is a solenoid valve, which is controlled by a controller to control the water flow in the branch pipe 17 and the opening and closing of the branch pipe 17. In addition, it should be noted that when the nozzle 6 is in use, only the end of the nozzle 6 leaks out of the side wall of the base 1, and it does not need to be fully extended. The nozzle 6 is located inside the base 1 when not in use, which can prevent the nozzle 6 from being damaged.

[0050] It should be noted that the first driving mechanism 9 controls the reciprocating deflection of the nozzle 6 so that the nozzle 6 has a fan-shaped spray range. It can be understood that in order to improve the maintenance effect of the bridge, multiple nozzles 6 can be arranged on the same base 1 so that the water flow sprayed by the nozzle 6 can be crossed to prevent the occurrence of spraying dead corners.

[0051] Furthermore, the water pipe 4 also includes: two connectors 10, which are respectively arranged at the water inlet end and the water outlet end. The water pipe 4 is connected to the water pipe 4 of another group of spray devices through the connectors 10.

[0052] In the above scheme, a plurality of spray devices are provided, and the water pipes 4 of the plurality of spray devices are connected end to end. It can be understood that when the bridge beam 18 is small, a single bridge beam 18 can be placed on one spray device, and when the bridge beam 18 is large, a single bridge beam 18 can be placed on a plurality of spray devices connected end to end. The device adopts a modular design, which can meet the placement of bridge beams 18 of different specifications, thereby improving the practicality of the device.

[0053] Furthermore, the branch pipe 17 includes: a pipe body, one end of which is connected to the side wall of the water pipe 4, and a first valve 8 is arranged on the pipe body; a telescopic cylinder 7, one end of which is connected to the end of the pipe body away from the water pipe 4, and the other end is connected to the end of the nozzle 6. When the second driving mechanism 5 drives the nozzle 6 to extend out of the side wall of the base 1, the telescopic cylinder 7 extends accordingly.

[0054] In the above scheme, the telescopic tube 7 can meet the telescopic requirements of the nozzle 6. When the nozzle 6 extends out of the side wall of the base 1, the telescopic tube 7 extends. When the nozzle 6 is retracted, the telescopic tube 7 retracts. The telescopic tube 7 can adopt a bellows.

[0055] Furthermore, the nozzle 6 has a water outlet 14, which is opened on the circumferential side wall of the nozzle 6 away from the telescopic tube 7. The opening direction of the water outlet 14 is perpendicular to the axial direction of the nozzle 6, or the water outlet 14 is arranged with a tendency to the side wall of the base 1, so as to achieve a good spraying effect on the bridge beam 18.

[0056] Furthermore, the first driving mechanism 9 includes: a rack 901, which is slidably arranged in the base 1; a gear 903, which is arranged on the nozzle 6, and the gear 903 is meshed with the rack 901; a first driver 902, which is arranged in the base 1, and the driving end of the first driver 902 is connected to the side wall of the rack 901, and the first driver 902 drives the rack 901 to slide, so that the gear 903 drives the nozzle 6 to rotate.

[0057] In the above scheme, the first driver 902 adopts a cylinder or an electric push rod. The first driver 902 drives the gear 903 to rotate by pushing the rack 901 to slide along the slide groove in the base 1. Since the second driving mechanism 5 has a limiting effect on the nozzle 6, the nozzle 6 can only rotate under the drive of the gear 903. The first driver 902 drives the rack 901 to move back and forth, so that the nozzle 6 sprays the side wall of the bridge beam 18 in a fan-shaped area.

[0058] Furthermore, the second driving mechanism 5 includes: a bidirectional screw 501, which is rotatably arranged in the base 1; a movable plate 502, which is threadedly connected to the bidirectional screw 501, and the movable plate 502 is rotatably connected to the tube body of the nozzle 6; a baffle 16 is arranged on the tube body of the nozzle 6, and the movable plate 502 abuts against the baffle 16; a driving component, which is arranged in the base 1, and the driving component is used to drive the screw to rotate.

[0059] In the above scheme, the driving assembly includes a motor 503, the output shaft of the motor 503 is fixedly connected to the first bevel gear 504, the first bevel gear 504 is meshed with the second bevel gear 505, the second bevel gear 505 is fixedly arranged at one end of the bidirectional lead screw 501, and both ends of the bidirectional lead screw 501 are rotatably connected to the inner wall of the base 1. When the nozzle 6 needs to be pushed out, the motor 503 drives the bidirectional lead screw 501 to rotate, so that the movable plate 502 drives the nozzle 6 to move out of the side wall of the base 1 by pushing the baffle 16 on the nozzle 6. When it needs to be retracted, the motor 502 only needs to drive the bidirectional lead screw 501 to reverse.

[0060] Furthermore, it also includes: a cover plate 11, which is covered on the base 1; a plurality of pads 19, which are evenly spaced on the cover plate 11, and the pads 19 are used to place the bridge beam 18. The pads 19 and the cover plate 11 are an integrated structure, and there is a gap between two adjacent pads 19. When the bridge beam 18 is placed on the pads 19, the gap can let in air, so that the bottom of the bridge beam 18 can be ventilated.

[0061] Furthermore, it also includes: a water collecting tank 12, which is arranged on both sides of the outer wall of the base 1; a filter 13, which is arranged in the water collecting tank 12; and a water outlet pipe 15, which is arranged on the water collecting tank 12, and the water outlet pipe 15 is located at the lower part of the filter 13. When spraying, the water used to complete the spraying work can flow into the water collecting tank 12 and be collected, and the impurities in the water can be filtered out by the filter 13, and then an external pipe is connected to the water outlet pipe 15, and one end of the external pipe away from the water outlet pipe 15 is placed in the pool, and the water in the water collecting tank 12 can enter the pool again after being collected, thereby reducing the waste of water resources.

[0062] Furthermore, it also includes: a pressure sensor 3, which is arranged on the water pipe 4 and located at the water inlet side, and is used to detect the water pressure in the water pipe 4. The pressure sensor 3 is electrically connected to the controller. When the water pump is started, the pressure sensor 3 detects that the water pressure in the water pipe 4 increases, and the pressure sensor 3 transmits the detection information to the controller, which controls the first valve 8, the first drive mechanism 9 and the second drive mechanism 5 to start, and then performs the subsequent spraying work.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
