Description

Technical Field

[0001] This utility model relates to the technical field of road and bridge processing, specifically a water spraying device for road and bridge processing. Background Technology

[0002] Road and bridge construction refers to the general term for processes such as concrete pouring, asphalt paving, component prefabrication, and curing involved in the construction of roads, bridges, and other transportation infrastructure. Water spraying devices are mainly used in this process to suppress construction dust to meet environmental protection requirements, while also keeping the concrete moist by spraying water mist to promote strength formation, and assisting in cooling and setting the asphalt after paving.

[0003] Currently, common road and bridge construction watering devices typically employ fixed spray structures, relying mainly on manual operation of simple nozzles or fixed pipes for watering. This method has significant drawbacks: firstly, traditional nozzles have a single spray angle and limited coverage, making it difficult to create a uniform water mist layer. This results in localized dryness or excessive wetness on the road and bridge construction surface, affecting both concrete curing and dust control. Secondly, for large-span road and bridge construction surfaces, the water mist from fixed spray devices is insufficient to effectively cover the edge areas. Therefore, a new watering device for road and bridge construction is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a water spraying device for road and bridge construction, addressing the shortcomings of the commonly used fixed spray structures in road and bridge construction, which rely on manual operation of simple nozzles or fixed pipes. This approach has significant drawbacks: firstly, traditional nozzles have a limited spray angle and coverage, making it difficult to create a uniform water mist layer, leading to localized dryness or excessive wetness on the construction surface, affecting concrete curing and failing to effectively suppress dust; secondly, for large-span road and bridge construction surfaces, the water mist from fixed spraying devices struggles to effectively cover edge areas.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water spraying device for road and bridge processing, comprising a water tank, a pipe connected to the bottom of the water tank, a water spraying component at the bottom of the pipe, and a swing component at the bottom of the water tank;

[0006] The sprinkler assembly includes a three-way pipe, with flanges at both ends of the three-way pipe connecting to horizontal pipes. One end of the horizontal pipe is connected to a conduit, and the lower surface of the conduit is connected to a first nozzle group and a second nozzle group.

[0007] The swing assembly includes a cylinder, two first collars and two second collars. The piston rod of the cylinder is fixedly connected to a moving plate. Two guide frames are fixedly connected to the bottom of the water tank. A traction rope moves through the inside of the guide frame. The two ends of the traction rope are fixedly connected to the two first collars respectively. A connecting frame fixed to the moving plate is fixedly sleeved on the outside of the traction rope. The two first collars are respectively sleeved on both sides of the three-way pipe.

[0008] Preferably, the first and second nozzle groups are each composed of several uniformly distributed nozzles. The nozzles of the first and second nozzle groups are fixed to the lower surface of the guide tube in an alternating arrangement. The nozzle axis of the first nozzle group is inclined to the lower left at 45°, and the nozzle axis of the second nozzle group is inclined to the lower right at 45°.

[0009] Preferably, the two second sleeves are respectively fitted onto the outside of the two horizontal pipes, and a spring connects the second sleeves to the water tank.

[0010] Preferably, the top of the aforementioned tee pipe is connected to the bottom end of the pipe, and a valve is installed on the outside of the pipe.

[0011] Preferably, the cylinder described above is installed at the bottom of the water tank, and a guide rail is fixedly connected to the bottom of the water tank, with the movable plate slidably connected between the guide rails.

[0012] Preferably, a protective cover is fixedly connected to the bottom of the water tank, and a sponge pad is fixedly connected to the inner bottom wall of the protective cover.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] This invention effectively solves the problem of limited coverage of traditional single-angle nozzles by setting up a first and second nozzle group arranged at an angle of 45° to form a cross-type water curtain spray, ensuring uniform wetting of the construction surface of large-span road and bridges. The cylinder-driven swing mechanism drives the nozzle group to move up and down reciprocally, so that the water mist can dynamically cover the edge area of ​​the construction surface, eliminating the coverage blind spots of traditional fixed spraying devices. The combined use of the nozzle group and the swing mechanism not only improves the uniformity of water spraying, but also achieves precise control of the humidity of concrete curing, significantly improving the concrete curing effect and dust suppression efficiency.

[0026] Example 1

[0027] In existing technologies, common road and bridge construction watering devices typically employ fixed spray structures, relying mainly on manual operation of simple nozzles or fixed pipes for watering. This method has significant drawbacks: firstly, traditional nozzles have a single spray angle and limited coverage, making it difficult to create a uniform water mist layer. This results in localized dryness or excessive wetness on the road and bridge construction surface, affecting both concrete curing and dust suppression; secondly, for large-span road and bridge construction surfaces, the water mist from fixed spray devices is insufficient to effectively cover the edge areas.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a water spraying device for road and bridge processing, including a water tank 1, a pipe 2 connected to the bottom of the water tank 1, a water inlet pipe 7 connected to the top of the water tank 1, water required for spraying is injected into the water tank 1 through the water inlet pipe 7, a flexible hose 3 connected to the middle part of the pipe 2, the flexible hose 3 improves the extensibility of the pipe 2, a water spraying component 5 is provided at the bottom of the pipe 2, a swing component 6 is provided at the bottom of the water tank 1, a support frame 10 is fixedly connected to the bottom of the water tank 1, and a roller is provided at the bottom of the support frame 10. When the water tank 1 is pushed to move, the roller rolls on the ground.

[0029] The sprinkler assembly 5 includes a three-way pipe 51, the top of which is connected to the bottom of the pipe 2. Water from the water tank 1 is injected into the three-way pipe 51 through the pipe 2. A valve 4 is installed on the outside of the pipe 2 to control the water output from the water tank 1. The two ends of the three-way pipe 51 are connected to a horizontal pipe 52 by flanges. One end of the horizontal pipe 52 is connected to a conduit 53. The lower surface of the conduit 53 is connected to a first nozzle group 54 and a second nozzle group 55. The first nozzle group 54 and the second nozzle group 55 are each composed of several evenly distributed nozzles. The nozzles of the first nozzle group 54 and the second nozzle group 55 are fixed to the lower surface of the conduit 53 in an alternating arrangement. The axis of the nozzles of the first nozzle group 54 is angled 45° to the lower left, and the axis of the nozzles of the second nozzle group 55 is angled 45° to the lower right. This design increases the spray range of the nozzles. The alternating bidirectional oblique spray design can form a cross water curtain and avoid spray blind spots.

[0030] Working principle or structural principle: After water is injected into the water tank 1 through the water inlet pipe 7, the valve 4 is opened to allow high-pressure clean water to flow into the three-way pipe 51 of the sprinkler assembly 5 through the pipe 2 and the hose 3, and then split to the horizontal pipes 52 and the guide pipe 53 on both sides. The first nozzle group 54 (slanted to the lower left 45°) and the second nozzle group 55 (slanted to the lower right 45°) below the guide pipe 53 spray synchronously in an alternating manner to expand the coverage area. The hose 3 cooperates with the flexible extension and contraction of the pipe 2 to achieve dynamic and uniform water spraying. The bidirectional staggered oblique spray design of the first nozzle group 54 and the second nozzle group 55 improves the spraying efficiency through complementary angles.

[0031] Example 2

[0032] The swing assembly 6 includes a cylinder 64, two first collars 61, and two second collars 69. The two second collars 69 are respectively sleeved on the outside of the two horizontal tubes 52. A spring 68 is connected between the second collars 69 and the water tank 1. The spring 68 supports the horizontal tubes 52 through the second collars 69. A movable plate 65 is fixedly connected to the piston rod of the cylinder 64. The cylinder 64 is installed at the bottom of the water tank 1, and the water tank 1 provides fixed support for the cylinder 64. A guide rail 66 is fixedly connected to the bottom of the water tank 1. The movable plate 65 is slidably connected between the guide rails 66 and slidably connected to the bottom of the water tank 1 through the guide rails 66. Two guide frames 67 are fixedly connected to the bottom of the water tank 1, and a traction rope moves through the interior of the guide frame 67. 62. The two ends of the traction rope 62 are fixedly connected to two first rings 61 respectively. The outer side of the traction rope 62 is fixedly sleeved with a connecting frame 63 fixed to the moving plate 65. The two first rings 61 are respectively sleeved on both sides of the three-way pipe 51. A protective cover 8 is fixedly connected to the bottom of the water tank 1. The protective cover 8 protects the swing component 6. A sponge pad 9 is fixedly connected to the inner bottom wall of the protective cover 8. The sponge pad 9 is used to buffer the three-way pipe 51 when it deviates, preventing it from impacting the protective cover 8. The protective cover 8 is made of 304 stainless steel, which has both rust prevention and impact resistance. The thickness of the sponge pad 9 is ≥10mm to fully absorb energy. The first rings 61 move up and down against the side wall of the protective cover 8.

[0033] Working principle or structural principle: When the sprinkler assembly 5 is working, the piston rod of the cylinder 64 pushes the moving plate 65 to slide back and forth along the guide rail 66, which drives the connecting frame 63 fixed to the moving plate 65 to move synchronously. The connecting frame 63 pulls the traction ropes 62 on both sides, so that the two first rings 61 alternately rise and fall inside the protective cover 8 (the two first rings 61 are sleeved on both sides of the three-way pipe 51), thereby causing the three-way pipe 51, the horizontal pipe 52 and the guide pipes 53 on both sides to swing up and down slightly. The spring 68 buffers the swing impact of the horizontal pipe 52 through the second ring 69. The sponge pad 9 provides buffer protection when the three-way pipe 51 deviates. The cylinder 64 links the first ring 61 and the second ring 69 through the traction rope 62, converting the horizontal reciprocating motion into the vertical oscillation of the three-way pipe 51, dynamically expanding the spray coverage of the first nozzle group 54 and the second nozzle group 55 of the sprinkler assembly 5. Spring 68 provides elastic restoring force to the swinging of horizontal tube 52 via the second ring 69, forming a complete closed-loop action chain of "cylinder 64 pushes → traction rope 62 pulls the first ring 61 → three-way tube 51 swings → spring 68 buffers". Spring 68 should be inspected and maintained regularly, and replaced promptly when a defective spring is found.

[0034] In summary, after water tank 1 is filled with water, high-pressure water flows through pipe 2 and hose 3 into three-way pipe 51, and is then diverted to horizontal pipe 52 and conduit 53. The first nozzle group 54 (45° to the left) and the second nozzle group 55 (45° to the right) arranged in a staggered pattern below conduit 53 spray in both directions, expanding the coverage area. At the same time, cylinder 64 drives moving plate 65 to drive connecting frame 63, and through traction rope 62, the first ring 61 is alternately raised and lowered, causing three-way pipe 51 to swing up and down. Spring 68 and sponge pad 9 buffer the swing impact. Through the complementary spray head angle and dynamic swing, the uniformity of spraying and coverage efficiency are significantly improved.
