Description

Technical Field

[0001] This utility model relates to the field of municipal building construction technology, specifically to a dust suppression device for municipal building construction. Background Technology

[0002] Municipal housing construction refers to the construction of houses within the planned construction area of ​​urban areas, towns, and villages. During the construction process, a large amount of dust is generated at the construction site, which can easily affect the lives of surrounding residents and the health of workers. Therefore, a dust suppression device is needed.

[0003] Publication number CN221732796U discloses a dust suppression device for municipal building construction. It uses an installation box to define the position of the lifting seat, which in turn defines the position of the lifting cylinder. A limiting component and the lifting cylinder define the position of the threaded rod. This facilitates fixing the lifting seat to raise and lower the lifting cylinder. When the limiting component rotates the threaded rod, it causes the lifting cylinder to rise and fall within the lifting seat, thereby raising and lowering the buffer box to adjust the spraying height and improve the dust suppression effect. However, this patent still has the following problems in actual use:

[0004] The installation box defines the position of the lifting seat, which in turn defines the position of the lifting cylinder. The limiting component and the lifting cylinder define the position of the threaded rod. This design facilitates the fixing of the lifting seat to raise and lower the lifting cylinder. When the limiting component drives the threaded rod to rotate, it can cause the lifting cylinder to rise and fall within the lifting seat, thereby raising and lowering the buffer box to adjust the spraying height and improve the dust suppression effect. However, when the water source enters the buffer box through the water pump and is sprayed out through the booster pipe and atomizing nozzle, it will generate a certain impact force. This will cause a certain impact force on the lifting assembly, which may lead to the breakage of the threaded rod and threaded sleeve in the lifting assembly.

[0005] A dust suppression device for municipal building construction is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a dust suppression device for municipal building construction, to solve the problem mentioned in the background art. The current method uses an installation box to limit the position of the lifting seat, the lifting seat to limit the position of the lifting cylinder, and a limiting component and lifting cylinder to limit the position of the threaded rod. This facilitates fixing the lifting seat to raise and lower the lifting cylinder, and when the limiting component drives the threaded rod to rotate, it can cause the lifting cylinder to rise and fall within the lifting seat, thereby raising and lowering the buffer box to adjust the spraying height and improve the dust suppression effect. However, when water enters the buffer box through the water pump and when water is sprayed out through the booster pipe and atomizing nozzle, a certain impact force is generated. This impact force can cause the lifting assembly to break, potentially leading to the breakage of the threaded rod and threaded sleeve in the lifting assembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for municipal building construction, comprising a base, wherein a plurality of casters are fixedly installed around the bottom surface of the base;

[0008] A water tank is fixedly installed on the top surface of the base. A water pump is fixedly installed on one side of the top surface of the water tank. A connecting pipe is fixedly connected to one side of the water pump. The side of the connecting pipe away from the water pump is connected to the water tank. A rubber tube is fixedly connected to the other side of the water pump. A lifting assembly is provided on the other side of the top surface of the water tank. The lifting assembly includes a connecting cylinder fixedly connected to the water tank.

[0009] Also includes:

[0010] The top surface of the connecting cylinder is symmetrically provided with limit clamping components;

[0011] The limiting clamping assembly includes a connecting block that is fixedly connected to the connecting cylinder;

[0012] A screw rod runs through the center of the connecting block.

[0013] Preferably, a bearing seat is rotatably connected to one side surface of the screw, a clamping plate is fixedly connected to the side surface of the bearing seat away from the screw, and a rubber pad is fixedly installed on the side surface of the clamping plate away from the bearing seat.

[0014] Preferably, a stepper motor is fixedly installed inside the connecting cylinder, and a threaded rod is fixedly connected to the top surface of the output end of the stepper motor.

[0015] Preferably, a threaded sleeve is threaded onto the surface of the threaded rod, and sliders are symmetrically installed on the two sides of the threaded sleeve near the bottom.

[0016] Preferably, the connecting cylinder has symmetrically formed sliding grooves inside, and the sliding grooves are slidably connected to the slider.

[0017] Preferably, a buffer tank is connected through the surface of the rubber tube away from the water pump, a flexible joint is connected through the surface of the buffer tank, a booster pipe is connected through the surface of the flexible joint away from the buffer tank, and an atomizing nozzle is connected through the surface of the booster pipe away from the flexible joint.

[0018] Preferably, an inlet pipe is connected through to one side of the water pump.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This dust suppression device for municipal building construction, by setting a limiting clamping component, allows the limiting clamping component to share the load of the threaded connection through the axial friction force generated by the radial force, reducing the stress on the thread teeth and lowering the risk of stripping and fatigue wear. At the same time, by setting a lifting component, the height of the atomizing nozzle can be adjusted, thereby improving the dust suppression effect to a certain extent. The specific details are as follows:

[0020] 1. By setting a limiting clamping assembly, after adjusting the height of the atomizing nozzle, the screw is manually rotated. The screw and connecting block are connected by a through thread, allowing the screw to move during rotation. Simultaneously, the screw and bearing seat are rotatably connected, ensuring that the screw's rotation does not cause the bearing seat to rotate, but the screw's movement does cause the bearing seat to move. This, in turn, causes the bearing seat to move the clamping plate and rubber pad, thus providing a limiting clamping effect on the threaded sleeve. As the limiting clamping assembly further adjusts the thread... The clamping of the sleeve allows the limiting clamping assembly to share the load of the threaded connection through the axial friction force generated by the radial force, reducing the stress on the thread teeth and lowering the risk of stripping and fatigue wear. At the same time, the rubber pad can increase the friction while avoiding direct contact between the clamping plate and the threaded sleeve, thus preventing wear on the threaded sleeve. Depending on the actual use, the screw is made of stainless steel or has a galvanized surface, and is equipped with weather-resistant rubber pads to reduce the risk of corrosion. Anti-loosening nuts or thread sealant can also be added to the screw to prevent loosening caused by vibration.

[0021] 2. By setting up a lifting component, when the height of the atomizing nozzle needs to be adjusted, the stepper motor is started by a control switch, causing the output end of the stepper motor to drive the rotation of the threaded rod. As the threaded rod rotates, it drives the movement of the threaded sleeve. Simultaneously, sliders are symmetrically arranged on the threaded sleeve, and the sliders are slidably connected to the sliding grooves. Through the cooperation between the sliders and the sliding grooves, the threaded sleeve can be driven to move. At the same time, the threaded sleeve is fixedly connected to the buffer box, which allows the movement of the buffer box when the threaded sleeve moves, thereby achieving the height adjustment of the atomizing nozzle. At the point where the threaded sleeve passes through the connecting cylinder, an elastic seal is set to make tight contact with the outer wall of the threaded sleeve. The radial pressure generated by the pre-compression is used to achieve a seal, while allowing the sleeve to slide. The elastic seal is made of polyurethane O-ring, and a retaining ring is added at the bottom of the sealing groove. The outer wall of the threaded sleeve is chrome-plated to reduce wear on the seal.

[0028] 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a dust suppression device for municipal building construction, including a base 1, with several casters 2 fixedly installed around the bottom surface of the base 1; a water tank 3 is fixedly installed on the top surface of the base 1, a water pump 4 is fixedly installed on one side of the top surface of the water tank 3, a connecting pipe 5 is fixedly connected to one side of the water pump 4, the side of the connecting pipe 5 away from the water pump 4 is connected to the water tank 3, a rubber tube 6 is fixedly connected to the other side of the water pump 4, and a lifting assembly 7 is provided on the other side of the top surface of the water tank 3, the lifting assembly 7 including a connecting cylinder 701 fixedly connected to the water tank 3; it also includes: limit clamping assemblies 8 symmetrically arranged on the top surface of the connecting cylinder 701; wherein, the limit clamping assembly 8 includes a connecting block 801 fixedly connected to the connecting cylinder 701; wherein, a screw 802 is connected through the middle of the interior of the connecting block 801, such as Figure 1-5As shown, by setting the limiting clamping component 8, the limiting clamping component 8 can share the load of the threaded connection through the axial friction force generated by the radial force, reduce the force on the thread teeth, and reduce the risk of stripping and fatigue wear. At the same time, by setting the lifting component 7, the height of the atomizing nozzle 12 can be adjusted, thereby improving the dust reduction effect to a certain extent. Meanwhile, the water pump 4 and the control switch are electrically connected.

[0030] A bearing housing 803 is rotatably connected to one side surface of the screw 802. A clamping plate 804 is fixedly connected to the side surface of the bearing housing 803 away from the screw 802. A rubber pad 805 is fixedly installed on the side surface of the clamping plate 804 away from the bearing housing 803. Figure 5 As shown, by manually rotating the screw 802, which is connected to the connecting block 801 by a through thread, the screw 802 can move during rotation. Simultaneously, the screw 802 is rotatably connected to the bearing housing 803. This means that the screw 802's rotation does not cause the bearing housing 803 to rotate, but its movement does cause the bearing housing 803 to move. This, in turn, causes the bearing housing 803 to move the clamping plate 804 and the rubber pad 805, thus providing a limiting clamping effect on the threaded sleeve 704. As the limiting clamping assembly 8 clamps the threaded sleeve 704, it can exert radial force... The axial friction force generated distributes the load of the threaded connection, reduces the stress on the thread teeth, and lowers the risk of stripping and fatigue wear. At the same time, the rubber pad 805 can increase the friction force while avoiding direct contact between the clamping plate 804 and the threaded sleeve 704, thus preventing wear on the threaded sleeve 704. Depending on the actual use, the screw 802 is made of stainless steel or has a galvanized surface, and is equipped with a weather-resistant rubber pad 805 to reduce the risk of corrosion. Anti-loosening nuts or thread sealant can also be added to the screw 802 to prevent loosening caused by vibration. At the same time, the clamping force is controlled by a preset torque value, such as by using a torque wrench to tighten, to ensure reliable limit and without damaging the threaded sleeve 704.

[0031] A stepper motor 702 is fixedly installed inside the connecting cylinder 701. A threaded rod 703 is fixedly connected to the top surface of the output end of the stepper motor 702. A threaded sleeve 704 is threaded onto the surface of the threaded rod 703. Slider blocks 705 are symmetrically installed on the two sides of the threaded sleeve 704 near the bottom. A sliding groove 706 is symmetrically opened inside the connecting cylinder 701, and the sliding groove 706 is slidably connected to the slider 705. Figure 4As shown, by setting up the lifting component 7, when the height of the atomizing nozzle 12 needs to be adjusted, the stepper motor 702 is started by the control switch, so that the output end of the stepper motor 702 drives the threaded rod 703 to rotate. As the threaded rod 703 rotates, it can drive the threaded sleeve 704 to move. At the same time, the threaded sleeve 704 is symmetrically provided with sliders 705, and the sliders 705 are slidably connected to the slide grooves 706. Through the cooperation between the sliders 705 and the slide grooves 706, the threaded sleeve 704 can be driven to move. Meanwhile, the threaded sleeve 704 is fixedly connected to the buffer box 9, which allows the threaded sleeve 704 to move while being lifted. The movement of the dynamic buffer box 9 allows for adjustment of the height of the atomizing nozzle 12. Simultaneously, at the point where the threaded sleeve 704 penetrates the connecting cylinder 701, elastic seals such as O-rings and lip seals are installed to ensure tight contact with the outer wall of the threaded sleeve 704. The radial pressure generated by the pre-compression achieves a seal while allowing the sleeve to slide. The elastic seals are polyurethane O-rings, and a retaining ring is added to the bottom of the sealing groove. The outer wall of the threaded sleeve 704 is chrome-plated to reduce wear on the seals. The stepper motor 702 is model 86BYG250-113, and it is electrically connected to the control switch.

[0032] A buffer tank 9 is connected to the surface of the rubber hose 6 away from the water pump 4. A flexible joint 10 is connected to the surface of the buffer tank 9. A booster pipe 11 is connected to the surface of the flexible joint 10 away from the buffer tank 9. An atomizing nozzle 12 is connected to the surface of the booster pipe 11 away from the flexible joint 10. Figure 1-3 As shown, the buffer tank 9 is equipped with a baffle or damping layer to further absorb the impact energy of the water flow and weaken the vibration transmission. At the same time, a flexible joint such as a high-pressure resistant rubber tube is installed at the connection between the booster pipe and the buffer tank to absorb the vibration generated by the jet reaction force and avoid direct transmission to the threaded connection structure.

[0033] A water inlet pipe 13 is connected to one side of the water pump 4, such as... Figure 3 As shown, the water inlet pipe 13 allows water to be added to the water tank 3. A water level monitor can also be installed inside the water tank 3 so that an alarm can be triggered when the water level in the water tank 3 drops to a certain level, thus reminding the staff to add water.

[0034] Working principle: Before using this type of dust suppression equipment for municipal building construction, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, firstly, by setting the limiting clamping component 8, after adjusting the height of the atomizing nozzle 12, the screw 802 is manually rotated. The screw 802 and the connecting block 801 are connected by a through thread, allowing the screw 802 to move during rotation. Simultaneously, the screw 802 and the bearing seat 803 are rotatably connected, ensuring that the screw 802 does not rotate the bearing seat 803 during rotation, but its movement does move the bearing seat 803. This, in turn, causes the bearing seat 803 to move the clamping plate 804 and the rubber pad 805, thus providing a limiting clamping effect on the threaded sleeve 704. As the limiting clamping assembly 8 clamps the threaded sleeve 704, the limiting clamping assembly 8 can share the load of the threaded connection through the axial friction force generated by the radial force, reducing the stress on the thread teeth and lowering the risk of stripping and fatigue wear. At the same time, the rubber pad 805 can increase the friction force while avoiding direct contact between the clamping plate 804 and the threaded sleeve 704, thus preventing wear of the threaded sleeve 704. In addition, depending on the actual use, the screw 802 is made of stainless steel or has a galvanized surface, and is equipped with a weather-resistant rubber pad 805 to reduce the risk of corrosion. Anti-loosening nuts or thread sealant can also be added to the screw 802 to prevent loosening caused by vibration.

[0035] Secondly, by setting up the lifting component 7, when the height of the atomizing nozzle 12 needs to be adjusted, the stepper motor 702 is activated by the control switch, causing the output end of the stepper motor 702 to drive the rotation of the threaded rod 703. As the threaded rod 703 rotates, it can drive the threaded sleeve 704 to move. At the same time, the threaded sleeve 704 is symmetrically provided with sliders 705, and the sliders 705 are slidably connected to the slide grooves 706. Through the cooperation between the sliders 705 and the slide grooves 706, the threaded sleeve 704 can be moved. Meanwhile, the threaded sleeve 704 and the buffer box 9 are fixed. The connection allows the threaded sleeve 704 to move, thereby adjusting the height of the atomizing nozzle 12. At the point where the threaded sleeve 704 penetrates the connecting sleeve 701, elastic seals such as O-rings and lip seals are installed to ensure tight contact with the outer wall of the threaded sleeve 704. The radial pressure generated by the pre-compression achieves a seal while allowing the sleeve to slide. The elastic seals are made of polyurethane O-rings, and a retaining ring is added at the bottom of the sealing groove. The outer wall of the threaded sleeve 704 is chrome-plated to reduce wear on the seals.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
