Description

Technical Field

[0001] The utility model relates to the technical field of construction dust removal, in particular to a dust removal device for highway engineering construction. Background Art

[0002] In highway engineering construction, dust is a key problem affecting the construction environment, endangering the health of personnel and the surrounding ecology. Trailer-type fog guns have been applied to a certain extent in the field of highway engineering dust removal due to their advantages of flexible movement and wide coverage.

[0003] However, the existing trailer-type fog guns have frequent problems in actual use. In terms of angle adjustment, there are obvious shortcomings in the existing trailer-type fog guns. The angle adjustment mechanism of traditional fog guns is simple, mostly relying on manual operation, with poor adjustment accuracy and a cumbersome process. When performing multi-angle spraying operations, construction workers need to repeatedly adjust the angle of the fog gun to adapt to different scenarios and dust distributions, which not only reduces construction efficiency but also increases labor intensity. Moreover, the adjustment mechanism lacks effective positioning and fixing devices, and the angle is prone to deviation when driving or under external force, resulting in inaccurate spraying direction and affecting the dust removal effect.

[0004] The existing trailer-type fog guns are commonly supported by outriggers or jacks, which is time-consuming and laborious. Construction workers need to manually unfold and adjust the height to ensure stability, requiring the cooperation of multiple people and it is difficult to control the adjustment accuracy. When encountering uneven ground, it is difficult to quickly adjust the support device to be horizontal, and the fog gun is prone to shaking and tilting during operation, which not only affects the spraying effect but also poses a safety hazard.

[0005] In addition, the atomization pipe of the fog gun has design defects. After the fog gun is used, liquid is likely to accumulate at the head of the atomization pipe and cannot be discharged in time. In a long-term humid environment, the accumulated liquid causes the metal components to rust and corrode, shortening the service life of the atomization pipe. The rusty atomization pipe affects the spraying effect and may also leak water, reducing the performance and reliability of the equipment. At the same time, it is necessary to regularly maintain and replace the rusty components, increasing the equipment cost. Summary of the Utility Model

[0006] In view of the above situation, to overcome the defects of the prior art, the utility model provides a dust removal device for highway engineering construction, which effectively solves the problems of inconvenient angle adjustment, laborious support operation, easy liquid accumulation and rust of the atomization pipe of the existing trailer-type fog guns, affecting the effect and increasing the cost through this design.

Detailed Embodiments

[0027] The following further elaborates on the detailed embodiments of the present invention in conjunction with the attached Figures 1-6 drawings.

[0028] The utility model includes a vehicle frame 101. A trailer hitch is provided on the left side of the vehicle frame 101 for connection with an automobile. Two tires are provided at the bottom of the vehicle frame 101 to facilitate the movement of the device. A bottom plate 102 is provided at the top of the vehicle frame 101. The bottom plate 102 is made of high-strength metal material and is subjected to special anti-corrosion treatment to ensure that it is not prone to rusting and damage during long-term use. A water tank 103 is provided on the left side of the top of the bottom plate 102. The water tank 103 is made of high-quality plastic and has good sealing performance and corrosion resistance. A pressurizing component is provided on the right side of the water tank 103. A fog cannon pipe 104 is provided on the right side of the pressurizing component. The pressurizing component is connected to the water tank 103 and the fog cannon pipe 104 through pipelines, and can stably convey the pressurized water into the fog cannon pipe 104. A fan is provided inside the fog cannon pipe 104 to generate a very fast-flowing air current inside the fog cannon pipe 104, which can convey the atomized water over a long distance for dust reduction in the construction area. Two positioning rods 108 are provided on the outer side of the fog cannon pipe 104. The two positioning rods 108 are arranged symmetrically front and back with the center line of the bottom plate 102 as the axis of symmetry. The bottom of the positioning rod 108 is connected to the top of the bottom plate 102. The positioning rod 108 provides stable support and positioning for the fog cannon pipe 104 to ensure that the fog cannon pipe 104 will not shake or shift during operation. An adjusting component is provided at the bottom of the fog cannon pipe 104. The adjusting component can realize the angle adjustment of the fog cannon pipe 104. A cross bar 304 is provided at the bottom of the adjusting component. A support component is provided at the bottom of the cross bar 304. Two support plates 307 are provided at the bottom of the support component. The two support plates 307 are arranged symmetrically left and right with the center line of the cross bar 304 as the axis of symmetry. By means of the adjusting component and the cross bar 304, the position of the support component and the two support plates 307 can be driven to change, so that when the angle of the fog cannon pipe 104 is adjusted, the two support plates 307 can move downward to quickly support the device.

[0029] The pressurizing component includes a water pump 105. The left side of the water pump 105 is connected to the water tank 103. The water pump 105 can pump out the water in the water tank 103. A water pipe 106 is provided on the right side of the water pump 105. The pressurized water of the water pump 105 enters the inside of the water pipe 106. A plurality of atomizing heads 107 are provided on the top of the water pipe 106. The inner side of the atomizing head 107 is connected to the fog cannon pipe 104. The pressurized water is sprayed out through the atomizing head 107 to cooperate with the fog cannon pipe 104 for large-area dust reduction operation.

[0030] The adjustment assembly includes a connecting rod 204. A threaded block 203 is provided at the bottom of the connecting rod 204. The bottom of the threaded block 203 is slidably connected to the bottom plate 102. A threaded rod 202 is provided inside the threaded block 203. The threaded rod 202 is rotatably connected to the bottom plate 102. A motor 201 is provided on the left side of the threaded rod 202. The motor 201 is connected to the bottom plate 102. When the motor 201 rotates, it can drive the threaded rod 202 to rotate. The threaded rod 202 drives the threaded block 203 connected by threads to move. The threaded block 203 can only move horizontally to the left and right. The movement of the threaded block 203 drives the connecting rod 204 connected by rotation to deflect, thereby realizing the adjustment of the angle of the fog cannon pipe 104. When the threaded block 203 is at the left end, the right side of the fog cannon pipe 104 tilts downward. When the threaded block 203 is at the middle position, the fog cannon pipe 104 becomes horizontal. When the threaded block 203 moves to the right end of the threaded rod 202, the right end of the fog cannon pipe 104 tilts upward to the maximum angle.

[0031] A connecting block 301 is provided at the rear side of the threaded block 203. The connecting block 301 passes through the bottom plate 102 and is fixedly connected to the threaded block 203. A limiting plate 302 is provided at the bottom of the connecting block 301. A groove is provided inside the limiting plate 302. The groove is composed of a horizontal line segment and an inclined line segment. A second cylindrical rod 308 is provided inside the limiting plate 302. The front end of the second cylindrical rod 308 is connected to a cross bar 304. The second cylindrical rod 308 is slidably connected to the limiting plate 302. A vertical plate 303 is provided in the middle of the cross bar 304. The top of the vertical plate 303 is connected to the bottom of the bottom plate 102. The vertical rod can restrict the cross bar 304 to only move vertically up and down. When the threaded block 203 moves to the right, the limiting plate 302 can be pulled to move to the right through the connecting block 301. At this time, the groove inside the limiting plate 302 drives the second cylindrical rod 308 to move downward. As the limiting plate 302 continues to move, when the second cylindrical rod 308 enters the horizontal stage, its position will no longer change.

[0032] The support assembly includes two support rods 305. The two support rods 305 are arranged symmetrically left and right with the center line of the cross bar 304 as the axis of symmetry. The top of the support rod 305 is rotatably connected to the bottom plate 102. A first cylindrical rod 306 is provided at the rear side of the support rod 305. The first cylindrical rod 306 is connected to the cross bar 304. When the cross bar 304 moves downward, it can restrict the two first cylindrical rods 306 from moving downward, thereby driving the support rods 305 to rotate inward. While the support rods 305 are rotating, the relative position of the first cylindrical rods 306 inside the cross bar 304 will change, thereby completing the adjustment of the angle of the support rods 305.

[0033] When the utility model is in use, the default initial state is that the right side of the fog cannon tube 104 inclines downward. At this time, the threaded block 203 moves to the leftmost side. Due to the self-locking characteristic of the threaded block 203 and the threaded rod 202, the angle of the fog cannon tube 104 will not change when the device moves. And at this time, the two support rods 305 are in a horizontal state, and the two support plates 307 are in a suspended state, which will not affect the movement of the vehicle frame 101.

[0034] When atomization operation is required, first move the device to the predetermined position, and then control the threaded block 203 to move to the right. During the movement, it can drive the connecting rod 204 to push the right side of the fog cannon tube 104 to gradually rotate upward, entering the spray dust reduction stage. While the fog cannon tube 104 rotates upward, it will drive the connecting block 301 to move to the right. Through the cooperation of the limiting plate 302 / vertical plate 303 and the cross bar 304, it can drive the cross bar 304 to move downward, thereby pushing the two support rods 305 to rotate downward simultaneously, making the two support plates 307 touch the ground to support the device. When the support is completed, the fog cannon tube 104 becomes horizontal.

[0035] Subsequently, the threaded block 203 continues to move to the right. At this time, it continues to drive the limiting plate 302 to move to the right. Since the second cylindrical rod 308 has moved to the horizontal groove section of the limiting plate 302 at this time, the positions of the support rod 305 and the support plate 307 no longer change. Thus, the upward inclination angle of the fog cannon tube 104 can be adjusted arbitrarily to change the spraying range of the fog cannon tube 104.

[0036] Finally, after the dust reduction operation is completed, control the threaded block 203 to move to the left, making the right side of the fog cannon tube 104 incline downward, which is convenient for discharging the remaining liquid in the atomizing head 107. At the same time, it drives the two support rods 305 to rotate outward and finally become horizontal, which is convenient for the movement of the vehicle frame 101.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model.
