Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bridge maintenance, and in particular to a bridge spraying maintenance device. Background Technology
[0002] Bridge maintenance has two meanings. In a narrow sense, bridge maintenance refers to the inspection, testing, evaluation, repair and reinforcement work carried out to ensure that the bridge is always in normal working condition. After the concrete of the bridge is poured, if the climate is hot and the air is dry, and maintenance is not carried out in time, the curing water in the concrete will evaporate too quickly, resulting in dehydration. This will prevent the cement particles that have formed a gel from fully hydrating and transforming into stable crystals, lacking sufficient bonding strength, which will cause flaking or powdering on the concrete surface. At this time, it is necessary to add water.
[0003] However, after the existing bridge deck is completed, daily maintenance is mostly carried out by manually spraying water trucks. This method is not only inefficient, but also prone to deviations in the coverage of the maintenance area, resulting in inadequate maintenance in some areas. Manual spraying maintenance may result in some areas being sprayed more while others are sprayed less, affecting the service life of the bridge. In response to this, this utility model provides a bridge spraying maintenance device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0022] Example: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The bridge spraying maintenance equipment shown includes a movable base plate 10. A water tank 20 is fixedly installed at one top end of the movable base plate 10. The water tank 20 is a hollow barrel structure. A rotating cylinder 30 is fixedly installed at the other top end of the movable base plate 10. A rotating column 31 is movably arranged at the center of the rotating cylinder 30. A base plate 32 is fixedly installed on the top of the rotating column 31 and is movable on the outer side of the top of the rotating cylinder 30. A spraying assembly is arranged on the top of the base plate 32, and the spraying assembly includes a spray nozzle. The base plate 32 has a spray seat 33, a side frame 40, and a movable block 41. The side frame 40 is fixedly installed on one end of the top of the base plate 32. The side frame 40 is a hollow square structure. The spray seat 33 is connected to the other end of the top of the base plate 32 through a rotating plate 34. A servo motor 42 is fixedly installed at the bottom of the side frame 40. The output end of the servo motor 42 is connected to a screw 43. The movable block 41 is threaded through the screw 43. The movable block 41 and the spray seat 33 are movably connected by a hinge rod 45 through a hinge 44.
[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom of the movable base plate 10 is fixed with traveling rollers 11 by bolts. The outer circumference of the traveling rollers 11 is provided with rubber to achieve effective protection of the bridge. The water tank 20 is fixed with a push handle 35 on the side away from the rotating cylinder 30. The top of the water tank 20 is fixed with bolts and a water pump 21 is fixed with bolts. The output end of the water pump 21 is connected to the spray seat 33 through the telescopic conduit 23. The top of the water tank 20 is provided with a water inlet 22 with a sealing cover. Several spray heads 36 are evenly installed on one side of the bottom of the spray seat 33 by bolts.
[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 4 A limiting rod 46 is fixedly installed inside the side frame 40. The two ends of the movable block 41 are movably inserted through the limiting rod 46. The side frame 40 has a movable slot 47, and the hinge rod 45 is movably inserted through the movable slot 47. A stepper motor 37 is fixedly installed at the bottom of the rotating cylinder 30. The output end of the stepper motor 37 is connected to the drive gear 38 through a rotating shaft. A rotating gear 39 is fixedly installed inside the rotating cylinder 30, and the rotating gear 39 is movably meshed with the drive gear 38. The back-and-forth movement of the drive gear 38 synchronously drives the rotating column 31 on the rotating gear 39 to move back and forth, thereby driving the spray seat 33 to spray the bridge maintenance area back and forth.
[0025] The working principle of this utility model is as follows: water is injected into the water tank 20 through the water inlet 22. The spraying seat 33 is moved to the area of the bridge that needs maintenance spraying by the push handle 35 on the water tank 20 in conjunction with the traveling rollers 11 under the moving base plate 10. Water is injected into the spraying seat 33 by the water pump 21 on the top of the water tank 20 in conjunction with the telescopic pipe 23. The spraying water in the spraying seat 33 is evenly sprayed onto the bridge maintenance area through the spray head 36.
[0026] During the spraying process, the stepper motor 37 drives the drive gear 38 to rotate. The drive gear 38 meshes with the rotating gear 39 to drive the rotating column 31 to rotate back and forth. The rotating column 31 drives the spray seat 33 on the base plate 32 to swing back and forth to spray and maintain the bridge. This ensures that the sprayed water is evenly covered on the bridge during the spraying and maintenance process, reducing the labor intensity of workers. At the same time, the bridge maintenance spraying coverage is even and thorough.
[0027] The movable block 41 on the screw 43 is driven by the servo motor 42 to move up and down under the action of the limit rod 46. During the movement, the movable block 41 drives the spray seat 33 on the rotating plate 34 to adjust the angle through the hinge 44, hinge rod 45 and movable groove 47. This allows the angle of the spray head 36 under the spray seat 33 to be adjusted with the angle of the bridge maintenance area. The spray seat 33 can be adjusted to effectively spray at different distances, and the adjustment is convenient.
[0028] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
