Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge maintenance, in particular to a spray cooling device used for road and bridge maintenance. Background Art

[0002] Road and bridge maintenance refers to the care and maintenance of roads and bridges. With the increasingly rapid economic development, the number of vehicles is increasing. In order to solve the problem of driving congestion and improve the driving environment and further improve driving safety, road and bridge construction has become an important means to solve the above problems.

[0003] Most of the existing road and bridge construction uses prefabricated concrete bridge sections. By replacing the traditional road and bridge construction method with the overlap assembly method between prefabricated concrete bridge sections, the construction efficiency of road and bridge construction can be further improved. In order to ensure driving safety, crash barriers are mostly installed on both sides of the road and bridge. However, when the hot weather continues in summer, when the temperature rises, the concrete will expand and contract, causing stress inside the crash barrier. If the temperature rises too quickly, it is easy to cause cracks, especially for long concrete buildings. It is more prone to cracking. Therefore, it is often necessary to spray and cool the crash barrier in summer. However, when the crash barrier is sprayed manually, it is not convenient to spray and maintain the outside of the crash barrier.

[0004] Therefore, we made improvements to this and proposed a spray cooling device for road and bridge maintenance. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figures 1 to 6 As shown, the utility model is a spray cooling device for road and bridge maintenance, comprising a base plate 1 and a push handle 2 fixedly connected to the base plate 1, a water supply assembly 3 for water supply is fixedly connected to the upper surface of the base plate 1, by utilizing the high-pressure water pump 33, the water pipe 32, and the atomizing nozzle 34 in the water supply assembly 3, the cooling water can be transported to the atomizing nozzle 34 through the water pipe 32 through the high-pressure water pump 33, the guide assembly 4 comprises a guide frame 41, the guide frame 41 is arranged in an inverted U-shaped structure, a water tank 411 is provided inside the guide frame 41, by utilizing the mutual communication between the water pipe 32 and the guide frame 41, the cooling water can be transported to the water tank 411 provided inside the guide frame 41, and then by arranging the water spraying end of the atomizing nozzle 34 to face the outer wall of the road and bridge crash barrier to be sprayed, the spray cooling operation can be performed on the two sides of the road and bridge crash barrier more conveniently and quickly.

[0023] There are multiple groups of atomizing nozzles 34. The atomizing nozzles 34 arranged on the lower surface of the upper frame of the guide frame 41 can spray and cool the top of the road and bridge crash barrier. By utilizing the combined effect of at least three groups of atomizing nozzles 34 evenly arranged in an array in the vertical direction on both sides of the guide frame 41, it can ensure that the surface of the road and bridge crash barrier is sprayed and cooled more fully, thereby further improving the efficiency of spraying and cooling the road and bridge crash barrier.

[0024] By utilizing the connecting rod 42 in the guide unit slidingly arranged on the inner walls on both sides of the guide frame 41, the guide roller 43 arranged on the connecting rod 42 and the sliding groove 412, the connecting rod 42 can slide inside the sliding groove 412, and the spring 413 fixedly connected between the sliding groove 412 and the slide plate 414 can further improve the flexibility of the guide roller 43. The rolling contact between the outer peripheral surface of the guide roller 43 and the wall surface of the road and bridge crash barrier to be maintained can further ensure that each atomizing nozzle 34 can spray and cool the surface of the road and bridge crash barrier, so that it can be suitable for road and bridge crash barriers of different thicknesses, thereby improving the adaptability of the device.

[0025] By fixing the limit plate 415 to the open end of the sliding groove 412 close to the guide roller 43, the sliding plate 414 slidably connected inside the sliding groove 412 can be further prevented from falling off from the open end of the sliding groove 412, thereby further improving the stability of the device.

[0026] By fixing the damping turntable 6 on the upper surface of the base plate 1, the hydraulic rod 5 connected is rotated on the damping turntable 6, and the output direction of the output end of the hydraulic rod 5 is set to a vertically upward mode, and fixedly connected to the bottom of the guide frame 41, the damping turntable 6 can be used to rotate the guide frame 41 to the outer wall of the water tank 31 after the use of the guide frame 41, thereby further reducing the space required for storing the device, making it more convenient to store and carry.

[0027] During operation, the guide frame 41 is lifted up in the vertical upward direction by using the hydraulic rod 5 until the bottom of the guide frame 41 is higher than the top of the road and bridge crash barrier, and then the two side rods of the U-shaped structure are respectively located on both sides of the wall of the road and bridge crash barrier through the damping turntable 6, so that the road and bridge crash barrier is located between the two side rods of the guide frame 41, and then the guide frame 41 is moved vertically downward by the hydraulic rod 5 until the bottom surface of the top rod of the guide frame 41 is slightly higher than the top of the road and bridge crash barrier and stops, and then the high-pressure water pump 33 is used to transport cooling water from the water tank 31 to the guide frame 41 through the water pipe 32, and then the wall of the road and bridge crash barrier is sprayed and cooled through the water tank 411 opened inside the guide frame 41 and the atomizing nozzle 34 connected to the water tank 411.

[0028] The utility model sets the guide frame 41 into a U-shaped structure so that both side rods of the guide frame 41 are located outside the road bridge crash barrier, and can spray and cool both sides of the road bridge crash barrier at the same time, which is more convenient and quick to use.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
