[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0028] The following describes an embodiment of this utility model based on its overall structure.
[0029] like Figures 1 to 4As shown, this utility model provides a dust suppression device for construction sites in urban rail engineering, including a platform 1. The top of the platform 1 is provided with a height adjustment component 2. The height adjustment component 2 includes an adjustment base 21. An adjustment housing 22 is fixed to the top of the adjustment base 21 by bolts. A first motor 23 is fixed inside the adjustment base 21. The end of the main shaft of the first motor 23 passes through the bottom of the adjustment housing 22 and is fixed with a screw 24. Limiting grooves 25 are opened at both the left and right points of the adjustment housing 22. An adjustment rod 26 is spirally sleeved on the outside of the screw 24. When the screw 24 rotates, the adjustment rod 26 will move up and down along the axis of the screw 24 to achieve height change. Limiting blocks 27 are fixed on both the left and right sides of the bottom of the adjustment rod 26. The limiting blocks 27 are slidably connected to the limiting grooves 25 to prevent the adjustment rod 26 from shaking when moving up and down and to ensure adjustment stability. A pitch seat 28 is symmetrically fixed on the top of the adjustment rod 26.
[0030] In this embodiment, a hydraulic lifting rod 3 is fixedly provided on the top of the platform 1. It can change its length through hydraulic extension and retraction to provide a stable pushing and pulling force. The height adjustment component 2 and the top of the hydraulic lifting rod 3 are provided with a pitch adjustment component 5. The pitch adjustment component 5 includes a mounting base 51. A pitch shaft 52 is fixedly provided on the bottom front side of the mounting base 51. A support shaft 53 is fixedly provided on the bottom rear side of the mounting base 51. The pitch shaft 52 is rotatably connected to the pitch seat 28. The support shaft 53 is rotatably connected to the hydraulic lifting rod 3. When the hydraulic lifting rod 3 extends and retracts, it pushes and pulls the mounting base 51 to rotate around the pitch shaft 52, thereby realizing the pitch angle change of the mounting base 51 and the upper component.
[0031] The top of the mounting base 51 is provided with a horizontal adjustment component 4, which includes a second motor 41. The end of the main shaft of the second motor 41 is fixedly provided with a worm gear 42. The left side of the worm gear 42 is engaged with a worm wheel 43, which can prevent the turntable 44 from rotating on its own when it stays at any angle. The top of the worm wheel 43 is fixedly provided with the turntable 44.
[0032] A sprayer 6 is fixedly installed on the top of the turntable 44 to convert water into mist. It has a high-pressure atomizing nozzle inside, which can pressurize the water from the water tank and atomize it into fine droplets, which are then sprayed out through the nozzle to control dust.
[0033] A water tank assembly 7 is fixedly installed on the top of the platform 1. The water tank assembly 7 includes a water tank body 71 for storing water required for dust suppression. A water inlet 72 is fixedly installed on the top of the water tank body 71.
[0034] A first connecting pipe 8 is fixedly installed on the rear side of the water tank body 71 to introduce water from the water tank body 71 into the water pump 9. The other end of the first connecting pipe 8 is fixedly installed with the water pump 9, which pressurizes the water in the water tank body 71 to the sprayer 6 to ensure the spray pressure and range of the mist droplets. A solenoid valve 10 is fixedly installed on the top of the water pump 9 to realize the automatic switching of the water circuit. A connecting hose 11 is fixedly installed on the front side of the water pump 9. The other end of the connecting hose 11 is fixedly connected to the sprayer 6. The connecting hose 11 can adapt to dynamic changes and avoid the pipe from being pulled and broken.
[0035] A push handle 13 is fixedly installed on the top rear side of platform 1, which can be used by construction personnel to push the device to move. Shock-absorbing universal brake wheels 12 are fixedly installed at the four corners of the bottom of platform 1. The shock-absorbing structure can buffer the impact of road bumps on the device during movement. The braking function can lock the wheels after the device stops to prevent the device from sliding.
[0036] The sprayer is existing technology and will not be described in detail. In addition, this utility model also includes a water pump and a solenoid valve, which are not the main technical points of this patent and will not be described in detail.
[0037] The working principle and process of a dust suppression device for urban rail construction sites:
[0038] When in use, open the water inlet 72 on the top of the water tank body 71 and inject clean water into the water tank through a water pipe or bucket until the rated capacity of the water tank is reached. Release the brake device of the shock-absorbing universal brake wheel 12. The construction worker holds the push handle 13 on the rear side of the top of the platform 1 and pushes the device to the dusty area of urban rail construction. Then lock the brake wheel to prevent the device from sliding during operation. Start the water pump 9 and open the solenoid valve 10 through the control button. At this time, the water in the water tank flows into the water pump 9 through the first connecting pipe 8. After being pressurized, it is delivered to the sprayer 6 through the connecting hose 11.
[0039] Based on the dust height at the construction site, the first motor 23 is started, driving the screw 24 to rotate. Because the limiting block 27 is embedded in the limiting groove 25 of the adjusting housing 22, the adjusting rod 26 is restricted from rotating. The adjusting rod 26 moves up and down along the screw 24 until the height of the sprayer 6 matches the dust coverage requirements. To address the difference in distance between the front and rear of the dust, the hydraulic lifting rod 3 is extended and retracted, pushing the support shaft 53 on the rear side of the bottom of the mounting base 51, causing the mounting base 51 to rotate around the pitch shaft 52 on the front side of the bottom, thereby adjusting the pitch angle of the sprayer 6. If the dust at the construction site is distributed over a large area, the second motor 41 is started, driving the worm gear 42 to rotate. The worm gear 42 meshes with and drives the worm wheel 43 to rotate slowly. The turntable 44 on the top of the worm wheel 43 synchronously drives the sprayer 6 to rotate horizontally. The rotation speed can be adjusted as needed to achieve horizontal coverage by the sprayer 6. The sprayer 6 atomizes the pressurized water into fine droplets and sprays them evenly onto the dusty area. The droplets combine with the dust particles in the air, causing the particles to become heavier and settle.
