Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to an auxiliary dust suppression device and method for building construction. Background Technology

[0002] With the continuous advancement of urbanization in my country, construction activities are becoming increasingly frequent, encompassing the entire process from earthwork excavation and foundation construction to main structure construction, decoration and finishing, and construction waste removal. However, dust pollution generated throughout the entire construction cycle has become a significant source of particulate matter in urban air, severely restricting the improvement of ecological environment quality and the green transformation and development of the construction industry, and posing a significant threat to the quality of life and health of surrounding residents.

[0003] Currently, dust suppression technologies commonly used in the construction industry are mainly divided into three categories: physical dust suppression, chemical dust suppression, and management control. Each technology has significant limitations in practical applications. Among these, mist cannons and adjustable spray structures, due to their angle adjustment capabilities, have become the most widely used dust suppression equipment. These devices generally use motor-driven angle adjustment to achieve automatic adjustment of pitch and horizontal angles. Their advantages lie in convenient operation, remote control capability, and reduced manual labor intensity.

[0004] However, construction sites are often in complex environments characterized by dust, humidity, and frequent vibration. The angle adjustment mechanism driven by the motor is exposed to this environment for a long time, making it prone to various malfunctions. Once a malfunction occurs, the angle adjustment function is completely disabled, making it impossible to make emergency adjustments. The specific defects are as follows: First, malfunctions are frequent and emergency response capabilities are lacking. Most of them are single motor driven designs without emergency manual adjustment structures. Once a malfunction occurs or there is a temporary power outage or inconvenience in reconnecting power at the construction site, the angle adjustment function is completely paralyzed. The equipment can only operate at a single angle and cannot adjust its direction according to the location of the dust source, forming a large area of ​​dust suppression blind zone and significantly reducing the effectiveness of dust control. Secondly, maintenance is cumbersome and downtime is long. The angle adjustment mechanism driven by the motor has a complex structure with many parts and high assembly precision requirements. After a failure, it requires professional personnel to disassemble, repair, and replace parts, resulting in high maintenance costs and long downtime. Thirdly, the adaptability and practicality are insufficient. The angle adjustment driven by the motor relies on a stable power supply. In remote construction areas, temporary work sites, and other scenarios where power access is inconvenient, the angle adjustment function cannot be used normally. In addition, the energy consumption of the motor drive mechanism is high, which will increase the operating cost of the equipment in the long run. Moreover, it cannot work at all when the power is off. The adaptability is difficult to meet the ever-changing operational needs of the construction site and cannot meet the actual use requirements.

[0005] Therefore, there is a need to provide an auxiliary dust suppression device and method for construction, which aims to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an auxiliary dust suppression device and method for building construction, which aims to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0014] As a further embodiment of the present invention, the pump body is also connected to a backup water tank via a third water guide pipe. The backup water tank is installed on both sides of the equipment box, and a storage battery is also installed inside the equipment box.

[0015] As a further embodiment of the present invention, the emergency drive mechanism further includes a fifth traction rod for manual adjustment by docking with the second traction rod. Both ends of the second and fifth traction rods are provided with ball heads. One end of the third and fourth traction rods is wrapped around the ball heads at both ends of the second and fifth traction rods by a ball head cover. An electric push rod is fixedly installed on one side of the connecting tube. The piston rod of the electric push rod is fixedly connected to a metal block. A magnet that magnetically docks with the metal block is provided in the groove block.

[0016] As a further embodiment of the present invention, the emergency drive mechanism further includes a hand control lever for manually adjusting the fifth traction lever. The fifth traction lever is rotatably mounted at both ends of the sixth traction lever, and the sixth traction lever is rotatably mounted inside the equipment box via a second connecting shaft. The hand control lever is fixedly mounted at the middle of the fifth traction lever, and a handle is fixedly connected to one end of the hand control lever.

[0017] As a further embodiment of the present invention, the emergency drive mechanism further includes a horizontal groove and a vertical groove for limiting the movement of the hand control lever. The horizontal groove and the vertical groove are formed on the equipment box. Each of the horizontal groove and the vertical groove is provided with a plurality of positioning grooves for limiting the docking of the hand control lever. A protective box is provided on the outside of the grip, and a box door is hinged on the protective box.

[0018] As a further embodiment of the present invention, a handrail is provided on the back side of the equipment box, and a number of casters for movement are provided on the bottom of the equipment box.

[0019] A method for using an auxiliary dust suppression device for construction work includes the following steps:

[0020] Step 1: When performing electrically adjustable spray dust suppression, the pump is moved by holding the handle on the outside of the equipment box and the casters at the bottom of the equipment box. The pump body is connected to an external water source for water supply through the water inlet pipe.

[0021] Step 2: The pump body injects water through the second water pipe into the nozzle on the first water pipe via the external water supply, and sprays it out to complete the dust suppression spraying on the outside. The output shaft of the first motor drives the second gear to rotate, which in turn drives the fan blades on the first water pipe to rotate and spray.

[0022] Step 3: The motor built into the motor base drives the spray nozzle connected to the first traction rod to adjust the horizontal angle, and the second motor drives the spray nozzle connected to the first traction rod to adjust the vertical angle.

[0023] Step 4: The motor built into the motor base and the second motor stop working. The battery in the equipment box provides power, and the pump body is connected to the backup water tank through the third water pipe to supply water for spray dust suppression.

[0024] Step 5: The electric push rod inside the connecting pipe drives the metal block to extend into the interior of the groove block, and the linear connection and fixation of the third and fourth traction rods is completed under the magnetic docking action of the magnet;

[0025] Step Six: Open the door of the protective case, and adjust the angle of the hand control lever by moving it along the horizontal and vertical grooves. The positioning groove can limit the adjustment of the hand control lever.

[0026] Step 7: When the fifth traction rod is driven by the hand lever to adjust the lateral angle, under the linear docking action of the fourth and third traction rods, and under the ball-head wrapping action of the ball-head wrapping shell, the first traction rod connected to the second traction rod can be driven to adjust the lateral angle simultaneously.

[0027] Step 8: When adjusting the vertical angle, the fifth traction rod is driven to pitch and rotate by the hand lever. Alternatively, the vertical angle can be adjusted by the ball head wrapping of the ball head shell and the linear connection of the third and fourth traction rods, which allows the second traction rod to pull the spray cover on the first traction rod.

[0028] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0029] This invention, through its spray dust suppression mechanism, can effectively expand the horizontal dust suppression coverage area, reduce dust dead zones, and adapt to dust generation points at different heights. It optimizes the droplet settling effect, improves dust suppression efficiency, and allows for free and coordinated adjustment of the horizontal and vertical angles, greatly enhancing the flexibility and targeting of dust suppression. The flexible adjustment of the spray angle facilitates the smooth progress of construction.

[0030] By setting up an emergency drive mechanism, the traditional dust suppression equipment is no longer limited by "failure upon power failure," forming an emergency-controllable dust suppression guarantee system. It can flexibly adapt to the dust control needs of different construction areas, different heights, and different terrains. At the same time, it improves the equipment's emergency response capabilities. The dust suppression function can be quickly restored through simple manual operation, ensuring construction progress, improving equipment utilization, and providing a reliable guarantee for the green, environmentally friendly, safe, and efficient advancement of building construction.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0046] See Figures 1-10 A dust suppression auxiliary device for construction work includes an equipment box 1, on which a spray hood 3 for dust suppression is movably mounted, and further includes:

[0047] The spray dust suppression mechanism is installed at the connection between the spray hood 3 and the equipment box 1. It is used for spray dust suppression by electrically driving the spray hood 3 to adjust the angle. The spray dust suppression mechanism includes a first water guide pipe 4 for spray docking, a first traction rod 7 for angle adjustment, and a first connecting shaft 17. One end of the first water guide pipe 4 is provided with a nozzle 5, and several fan blades 6 are provided on the first water guide pipe 4. The first water guide pipe 4 is rotatably mounted on the first traction rod 7, the first traction rod 7 is rotatably mounted on the first connecting shaft 17, and the first connecting shaft 17 is rotatably mounted inside the equipment box 1.

[0048] Furthermore, the spray dust suppression mechanism also includes a pump body 14 for water injection. The other end of the first water guide pipe 4 is connected to the pump body 14 via a second water guide pipe 13. The pump body 14 is provided with a water inlet pipe 15. The first water guide pipe 4 is rotatably installed at the end of the second water guide pipe 13 and is located inside the protective shell 11. The spray cover 3 is fixedly installed on the first water guide pipe 4. The second water guide pipe 13 extends out of the outer side of the protective shell 11 and the joint with the equipment box 1 is made of elastic hose material.

[0049] Furthermore, the spray dust suppression mechanism also includes a first motor 10 for driving the first water guide pipe 4 to rotate. A first gear 8 is fixedly installed on the first water guide pipe 4. The first gear 8 is meshed with a second gear 9. The second gear 9 is fixedly connected to the output shaft of the first motor 10. The first gear 8, the second gear 9 and the first motor 10 are all installed on the outside of the first traction rod 7 through a protective shell 11. An elastic cloth 12 is provided at the joint between the first traction rod 7 and the equipment box 1.

[0050] Furthermore, the spray dust suppression mechanism also includes a motor base 16 and a second motor 18 for driving the first water guide pipe 4 to adjust its angle. The first traction rod 7 is rotatably mounted on the motor base 16, and the motor base 16 has a motor for adjusting the lateral angle built in. The motor base 16 is fixedly mounted on the middle of the first connecting shaft 17, and the first connecting shaft 17 is fixedly connected to the output shaft of the second motor 18. The second motor 18 is fixedly mounted in the equipment box 1, and the bottom of the motor base 16 is fixedly connected to the second traction rod 19.

[0051] Furthermore, a backup water tank 40 is connected to the pump body 14 via a third water guide pipe 41. The backup water tank 40 is installed on both sides of the equipment box 1, and a storage battery 42 is also installed inside the equipment box 1.

[0052] Furthermore, a handrail 39 is provided on the back side of the equipment box 1, and several casters 2 for movement are provided on the bottom of the equipment box 1.

[0053] Preferably, in areas where an external power source can be connected, when performing electrically adjustable spray dust suppression, the device can be moved in advance by the handle 39 on the outside of the handheld device box 1 and the casters 2 at the bottom of the device box 1. The pump body 14 is connected to an external water source for water supply through the water inlet pipe 15, and the battery 42 installed in the device box 1 is used as a backup power source.

[0054] The pump body 14 is supplied with water from an external source, which facilitates the injection of water through the second water pipe 13 into the nozzle 5 on the first water pipe 4 for spraying, thereby completing the external spray dust suppression treatment. The output shaft of the first motor 10 drives the second gear 9 to rotate, thereby synchronously driving the fan blade 6 on the first water pipe 4 to rotate, which can make the spraying speed faster and the range wider.

[0055] When performing electric angle adjustment, the motor built into the motor base 16 can drive the spray hood 3 connected to the first traction rod 7 to perform lateral angle adjustment, and the second motor 18 can correspondingly drive the spray hood 3 connected to the first traction rod 7 to perform vertical angle adjustment. At this time, since the metal block 25 set in the connecting pipe 23 is not linearly connected, the angle adjustment can be achieved by bending the elastic tube 27 on the connecting pipe 23 to avoid the misalignment.

[0056] This method of horizontal and vertical adjustment can effectively expand the coverage of horizontal dust suppression, reduce dust dead zones, adapt to dust generation points at different heights, optimize droplet settling effect, and improve dust suppression efficiency. The free and coordinated adjustment of horizontal and vertical angles greatly enhances the flexibility and targeting of dust suppression, and the flexible adjustment of spray angle facilitates the smooth progress of construction.

[0057] like Figures 1 to 11 As shown, this embodiment, based on the above embodiment, also includes an emergency drive mechanism, which is installed on the equipment box 1 and is used to manually drive the spray hood 3 for angle adjustment spray dust suppression. The emergency drive mechanism includes a third traction rod 20, a fourth traction rod 22 and a connecting pipe 23 for emergency docking. The connecting pipe 23 is provided with an elastic tube 27 for bending and turning. The connecting pipe 23 is provided with a metal block 25 and a groove block 26 for straight docking. The metal block 25 is adapted to be docked and installed on the groove block 26.

[0058] Furthermore, the emergency drive mechanism also includes a fifth traction rod 29 for manual adjustment by docking with the second traction rod 19. Both ends of the second traction rod 19 and the fifth traction rod 29 are provided with ball heads. One end of the third traction rod 20 and the fourth traction rod 22 are wrapped around the ball heads at both ends of the second traction rod 19 and the fifth traction rod 29 by ball head enclosure 21. An electric push rod 24 is fixedly installed on one side inside the docking pipe 23. The piston rod of the electric push rod 24 is fixedly connected to a metal block 25. A magnet 28 that magnetically docks with the metal block 25 is provided in the groove block 26.

[0059] Furthermore, the emergency drive mechanism also includes a hand control lever 30 for manually adjusting the fifth traction lever 29. The fifth traction lever 29 is rotatably mounted at both ends of the sixth traction lever 32, and the sixth traction lever 32 is rotatably mounted inside the equipment box 1 via the second connecting shaft 33. The hand control lever 30 is fixedly mounted at the middle of the fifth traction lever 29, and a handle 31 is fixedly connected to one end of the hand control lever 30.

[0060] Furthermore, the emergency drive mechanism also includes a horizontal groove 34 and a vertical groove 35 for limiting the movement of the hand control lever 30. The horizontal groove 34 and the vertical groove 35 are provided on the equipment box 1. Both the horizontal groove 34 and the vertical groove 35 are provided with a number of positioning grooves 36 for limiting the docking of the hand control lever 30. A protective box 37 is provided on the outside of the handle 31. A box door 38 is hinged on the protective box 37.

[0061] Preferably, in this embodiment, for some areas where external power and water sources cannot be connected, the battery 42 cannot drive multiple motors. At this time, the motor built into the motor base 16 and the second motor 18 stop working, and the battery 42 in the equipment box 1 provides power. At this time, the pump body 14 is connected to the backup water tank 40 through the third water pipe 41 to perform water supply spray dust suppression operation.

[0062] The electric push rod 24 inside the connecting pipe 23 drives the metal block 25 to extend into the interior of the recessed block 26. Under the magnetic docking action of the magnet 28, the third traction rod 20 and the fourth traction rod 22 can be linearly docked and fixed. At this time, the angle can be adjusted by opening the box door 38 on the protective box 37 and using the handle 31 on the hand control rod 30 to move it in the range of the horizontal groove 34 and the vertical groove 35. The positioning groove 36 can limit the adjustment of the hand control rod 30 accordingly. The specific operation method is as follows: when the fifth traction rod 29 is adjusted laterally by using the hand control rod 30, Under the linear connection of the fourth traction rod 22 and the third traction rod 20, and the ball-head wrapping action of the ball-head wrapping shell 21, the first traction rod 7 connected to the second traction rod 19 can be driven to adjust the lateral angle simultaneously. When adjusting the vertical angle, when the fifth traction rod 29 is driven to pitch and rotate by the hand control rod 30, the ball-head wrapping of the ball-head wrapping shell 21 and the linear connection of the third traction rod 20 and the fourth traction rod 22 can also be used to adjust the vertical angle of the spray cover 3 on the first traction rod 7 by the second traction rod 19, which is convenient for emergency manual adjustment.

[0063] It should be noted that the second motor 18 is not equipped with a brake for limit control when there is no power supply, thus facilitating vertical angle adjustment.

[0064] This emergency manual adjustment method breaks the limitation of traditional dust suppression equipment that "fails when power is off," forming an emergency controllable dust suppression guarantee system. It can flexibly adapt to the dust control needs of different construction areas, different heights, and different terrains, while improving the equipment's emergency response capabilities. The dust suppression function can be quickly restored through simple manual operation, ensuring construction progress, improving equipment utilization, and providing a reliable guarantee for the green, environmentally friendly, safe, and efficient advancement of building construction.

[0065] A method for using an auxiliary dust suppression device for construction work includes the following steps:

[0066] Step 1: When performing electrically adjustable spray dust suppression, the pump body 14 is operated and moved by the handle 39 on the outside of the handheld equipment box 1 and the moving wheels 2 at the bottom of the equipment box 1. The pump body 14 is connected to an external water source for water supply through the water inlet pipe 15.

[0067] Step 2: Pump body 14 injects water through the second water pipe 13 into the nozzle 5 on the first water pipe 4 via the external water supply to spray out the water, thus completing the dust suppression spraying on the outside. The output shaft of the first motor 10 drives the second gear 9 to rotate, which in turn drives the fan blades 6 on the first water pipe 4 to rotate and spray.

[0068] Step 3: The motor built into the motor base 16 drives the spray cover 3 connected to the first traction rod 7 to perform horizontal angle adjustment, and the second motor 18 drives the spray cover 3 connected to the first traction rod 7 to perform vertical angle adjustment.

[0069] Step 4: The motor built into the motor base 16 and the second motor 18 stop working. The battery 42 in the equipment box 1 provides power. The pump body 14 is connected to the backup water tank 40 through the third water pipe 41 to supply water for spray dust suppression.

[0070] Step 5: The electric push rod 24 inside the connecting pipe 23 drives the metal block 25 to extend into the interior of the groove block 26, and the linear docking and fixing of the third traction rod 20 and the fourth traction rod 22 is completed under the magnetic docking action of the magnet 28.

[0071] Step 6: Open the door 38 on the protective box 37, and adjust the angle of the hand lever 30 by moving the handle 31 on the hand lever 30 to the horizontal groove 34 and the vertical groove 35. The positioning groove 36 can limit the adjustment of the hand lever 30.

[0072] Step 7: When the fifth traction rod 29 is driven by the hand control lever 30 to adjust the lateral angle, under the linear docking action of the fourth traction rod 22 and the third traction rod 20, and under the ball head wrapping action of the ball head wrapping shell 21, the first traction rod 7 connected to the second traction rod 19 can be driven to adjust the lateral angle simultaneously.

[0073] Step 8: When adjusting the vertical angle, the fifth traction rod 29 is tilted and rotated by the hand control lever 30. Alternatively, the vertical angle can be adjusted by the ball head wrapping of the ball head cover 21 and the linear connection of the third traction rod 20 and the fourth traction rod 22, which allows the second traction rod 19 to pull the spray cover 3 on the first traction rod 7.

[0074] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
