Description

Technical Field

[0001] The present invention relates to the technical field of dust reduction in construction, and particularly to a dust reduction device for construction. Background Art

[0002] With the acceleration of the urbanization process, construction activities are becoming increasingly frequent. These construction activities not only promote economic development but also bring many environmental problems, among which dust pollution is particularly prominent. Operations such as earth excavation, material stacking, and vehicle driving during the construction process will all cause a large amount of dust, seriously affecting the surrounding air quality, threatening the health of on-site workers and surrounding residents, and may also lead to reduced visibility and affect traffic safety.

[0003] Currently, there are already some methods and technologies in the market for reducing dust at construction sites. For example, using sprinkler trucks to regularly spray water on the construction site to suppress dust; using covering materials to cover materials and exposed ground that are prone to generating dust; setting up fences to block the spread of dust, etc., or using fog guns for dust reduction.

[0004] Among them, fog gun dust reduction is a currently widely used and relatively convenient method. The dust reduction fog gun, also known as a spray dust removal device or a spray dust reduction machine, is a professional device specifically designed to reduce dust and particulate matter in the air. It atomizes water into tiny water droplets through high pressure. These water droplets can combine with dust particles in the air, making the dust particles heavier and then settling to the ground, thereby achieving the effect of dust reduction. Fog guns are widely used in construction sites, mines, ports, landfills and other places prone to generating dust, and are an important means to effectively control environmental pollution.

[0005] The working principle of the fog gun mainly includes the following: 1. Water atomization: Press water into a special nozzle through a high-pressure pump, and the nozzle breaks the water flow into fine water mist particles. 2. Aerodynamic effect: The diameter of the water mist particles generated by the fog gun is very small, generally between a few micrometers and dozens of micrometers. Such a size enables them to suspend in the air for a period of time and collide with dust particles in the air. 3. Dust settlement: When the water mist particles come into contact with the dust particles, they will adhere to the surface of the dust particles, increasing the mass of the dust particles and accelerating their settlement.

[0006] Existing fog gun devices include mechanisms such as a gun barrel and a base. At the construction site, due to the continuous change of the construction location, the dust reduction device also needs to be continuously moved. Therefore, traveling wheels are usually installed on the base of the dust reduction device. However, after the dust reduction device reaches the designated position, due to the complex construction site environment, it is easy to cause the dust reduction device to move under the action of external forces or strong winds, affecting the progress of the dust reduction work.

[0007] Therefore, the present invention provides a dust reduction device for construction to solve the above problems. Summary of the Invention

[0008] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a dust reduction device for building construction, effectively solving the problem that the dust reduction device is offset during use, affecting the progress of the dust reduction work.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A dust reduction device for building construction, including a support mechanism, a dust reduction mechanism is arranged on the support mechanism, the dust reduction mechanism is connected to the support mechanism through a connection mechanism, the support mechanism includes a base, a receiving cavity is opened in the base, a through hole with an upward opening is arranged on the top wall of the receiving cavity, a moving member is arranged at the bottom of the receiving cavity, the moving member includes sliding grooves with downward openings symmetrically opened on the bottom wall of the receiving cavity, two sliding frames are symmetrically and fixedly connected to the bottom wall of the receiving cavity, the sliding frames communicate with the sliding grooves, a sliding plate is slidably connected in the sliding grooves, two moving wheels are symmetrically arranged on the bottom surface of the sliding plate, and the moving wheels are rotatably connected to the sliding plate.

[0010] Specifically, in the initial state, the moving wheels protrude from the bottom surface of the base and are in contact with the ground. When the dust reduction device needs to be moved, the base is pushed, and under the action of the moving wheels, the base moves on the ground; when the fog cannon works, the sliding plate is moved upward, the sliding plate slides into the sliding frame from the sliding groove, and at the same time the sliding plate drives the moving wheels to move upward, so that the moving wheels enter the sliding grooves, so that the moving wheels are separated from the ground.

[0011] Through the setting of the moving member, when the dust reduction device needs to be moved, the base can be driven to move on the ground through the moving wheels, so as to facilitate the movement of the dust reduction device; when the dust reduction device needs to work, the moving wheels can be separated from the ground by moving the sliding plate upward, so that the base is directly in contact with the ground, making the dust reduction device more stably placed on the ground, so that the subsequent dust reduction work is more stable.

[0012] Preferably, a connecting plate is fixedly connected to the upper ends of the two sliding plates together, and a return spring is connected between the connecting plate and the bottom wall of the receiving cavity.

[0013] Specifically, during use, when the sliding plate moves upward, the sliding plate drives the connecting plate to move upward, and the connecting plate stretches the return spring; when the sliding plate needs to be reset, the base is moved upward, and the connecting plate moves downward under the action of the return spring, thereby driving the sliding plate to reset, so that the moving wheels are reset.

[0014] Preferably, a locking member is provided on the connecting plate. The locking member includes a rod sleeve fixedly connected to the bottom wall of the receiving cavity. A fixing block is fixedly connected to the rod sleeve. An opening penetrating through the connecting plate vertically is formed on the connecting plate. The fixing block is located in the opening. Two mounting grooves opening outwards are symmetrically formed in the fixing block. A locking block is slidably connected in the mounting groove. A compression spring is connected between the locking block and the mounting groove. A clamping groove is formed on the side wall of the opening. The locking block is inserted into the clamping groove.

[0015] Specifically, during use, when the moving wheel needs to move upwards, move the locking block to compress the compression spring, so that the locking block moves out of the clamping groove, thereby unlocking the connecting plate.

[0016] Through the arrangement of the locking member, the connecting plate can be locked, so that the moving wheel can drive the base to move, facilitating the movement of the dust reduction device.

[0017] Preferably, the locking member further includes a contact rod slidably connected to the fixing block. The contact rod extends into the mounting groove. The top surface of the locking block is an inclined surface. The contact rod can contact the inclined surface of the locking block. An abutting ring is fixedly connected to the top end of the contact rod. An abutting rod is slidably connected in the rod sleeve. The abutting rod extends upwards out of the through hole. The abutting rod is in threaded fit connection with the through hole. A buffer spring is connected between the abutting rod and the rod sleeve. A moving rod is arranged on the abutting rod. The moving rod can contact the abutting ring.

[0018] Specifically, during use, when the locking member needs to be unlocked, rotate the abutting rod to make the abutting rod move downwards. When the abutting rod moves downwards, the abutting rod drives the moving rod to move downwards. The moving rod contacts the abutting ring, causing the abutting ring to move downwards. The abutting ring drives the contact rod to move downwards. The contact rod contacts the inclined surface of the locking block, causing the locking block to move out of the clamping groove.

[0019] Through the arrangement of the locking member, the unlocking of the locking member can be realized by pressing the abutting rod, so that the connecting plate can move, and thus the moving wheel can move upwards and retract into the base, making the dust reduction work more stable.

[0020] Preferably, two stabilizing mechanisms are symmetrically arranged on the base. The stabilizing mechanism includes an extension plate slidably connected to the base. Two sliding rods are symmetrically and fixedly connected to the extension plate. The sliding rods extend into the receiving cavity. A return spring is connected between the end of the sliding rod and the side wall of the receiving cavity.

[0021] Specifically, during use, when the moving wheel enters the receiving cavity, move the sliding rod to drive the extension plate to move away from the base, and at the same time, the sliding rod compresses the return spring.

[0022] Through the arrangement of the extension plate, after the moving wheel enters the accommodation cavity, the extension plate can extend out from the base, so that the extension plate and the sliding rod support the base, preventing the base from shifting or tipping under the action of external forces.

[0023] Preferably, the stabilizing mechanism further includes an oil cylinder fixedly connected to the bottom wall of the accommodation cavity. A push rod is slidably connected in the oil cylinder. The push rod extends out of the base. The push rod is fixedly connected to the extension plate. The oil cylinder is communicated with a connecting pipe, and the connecting pipe is communicated with the internal space of the rod sleeve. Hydraulic oil is provided in the rod sleeve.

[0024] Specifically, when the abutting rod moves downward, the abutting rod presses the hydraulic oil in the rod sleeve into the oil cylinder through the connecting pipe. Since the hydraulic oil in the oil cylinder increases, the push rod extends out of the oil cylinder, so that the push rod drives the extension plate to move away from the base.

[0025] Through the arrangement of the oil cylinder, when the abutting rod moves downward, the abutting rod can push the hydraulic oil in the rod sleeve into the oil cylinder, so that the push rod extends, driving the extension plate to extend, making the contraction of the moving wheel and the extension of the extension plate form a linkage, making the support for the base more coherent and stable.

[0026] Preferably, the dust reduction mechanism includes a barrel. One end of the barrel is fixedly connected with an annular nozzle group. The nozzle group includes twenty nozzles arranged along the circumferential direction. The nozzle group is communicated with a water pipe. A water pump is arranged on the base. The input end of the water pump is communicated with the accommodation cavity. Water is accommodated in the accommodation cavity. The output end of the water pump is communicated with the water pipe.

[0027] Specifically, when in use and dust reduction is required, start the water pump. The water pump pumps the water in the accommodation cavity into the water pipe, and then the water is sprayed out through the nozzles to achieve the dust reduction work.

[0028] Through the arrangement of the accommodation cavity, water can be accommodated in the accommodation cavity, enabling the water pump to pump out the water for dust reduction work, and increasing the weight of the base, further improving the stability of the base, thus maintaining the stability of the dust reduction work.

[0029] Preferably, the dust reduction mechanism further includes a pneumatic motor fixedly connected in the barrel. The output end of the pneumatic motor is fixedly connected with a blade.

[0030] Specifically, when dust reduction is required, start the pneumatic motor. The pneumatic motor drives the blade to rotate, and the blade drives the air to flow, blowing the water sprayed out by the nozzles outward.

[0031] Preferably, the connecting mechanism includes two electric push rods fixedly connected to the base. The top end of each electric push rod is rotatably connected to the barrel, and a damping member is provided at the rotational connection between the electric push rod and the barrel.

[0032] Specifically, during use, the electric push rods are activated, causing the top output ends of the electric push rods to move up and down. The output ends of the electric push rods drive the barrel to move, adjusting the dust suppression range and angle.

[0033] Furthermore, the electric push rod is a prior art and will not be elaborated here. Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the arrangement of the moving member, when the dust suppression device needs to be moved, it can drive the base to move on the ground through the moving wheels, facilitating the movement of the dust suppression device; when the dust suppression device needs to work, by moving the sliding plate upward, the moving wheels can be disengaged from the ground, enabling the base to directly contact the ground, making the dust suppression device more stably placed on the ground and ensuring more stable subsequent dust suppression work.

[0034] 2. Through the arrangement of the locking member, the locking member can be unlocked by pressing the abutting rod, enabling the connecting plate to move, and thus the moving wheels can move upward and retract into the base, making the dust suppression work more stable.

[0035] 3. Through the arrangement of the extension plate, after the moving wheels enter the accommodation cavity, the extension plate can extend from the base, and the extension plate and the sliding rod support the base, preventing the base from shifting or tipping under external forces. Through the arrangement of the oil cylinder, when the abutting rod moves downward, the abutting rod can push the hydraulic oil in the rod sleeve into the oil cylinder, causing the push rod to extend, thereby driving the extension plate to extend, forming a linkage between the retraction of the moving wheels and the extension of the extension plate, making the support for the base more coherent and stable.

[0036] 4. Through the arrangement of the accommodation cavity, the accommodation cavity can hold water, enabling the water pump to pump out the water for dust suppression work and increasing the weight of the base, further improving the stability of the base and maintaining the stability of the dust suppression work.

[0039] The following will refer to the accompanying drawings to describe each embodiment of the present invention in detail. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0040] As Figure 1 、 2As shown in Figures 3 and 4, an embodiment of the present invention discloses a dust removal device for construction, comprising a supporting mechanism 1, on which a dust reduction mechanism 2 is arranged, and the dust reduction mechanism 2 is connected to the supporting mechanism 1 via a connecting mechanism 3, the supporting mechanism 1 comprises a base 11, in which a accommodating chamber 12 is provided, and a top wall of the accommodating chamber 12 is provided with a through hole 13 opening upward, and a moving member 14 is provided at the bottom of the accommodating chamber 12, and the moving member 14 comprises a sliding groove 141 symmetrically arranged on the bottom wall of the accommodating chamber 12 and opening downward, and two sliding frames 142 are symmetrically fixedly connected to the bottom wall of the accommodating chamber 12, and the sliding frame 142 is communicated with the sliding groove 141, and a sliding plate 143 is slidably connected in the sliding groove 141, and two moving wheels 144 are symmetrically arranged on the bottom surface of the sliding plate 143, and the moving wheels 144 are rotatably connected to the sliding plate 143.

[0041] Specifically, in the initial state, the moving wheel 144 protrudes from the bottom surface of the base 11, and the moving wheel 144 is in contact with the ground. When the dust suppression device needs to be moved, the base 11 is pushed, and under the action of the moving wheel 144, the base 11 moves on the ground; when the fog cannon is working, the sliding plate 143 is moved upward, and the sliding plate 143 slides from the sliding groove 141 into the sliding frame 142. At the same time, the sliding plate 143 drives the moving wheel 144 to move upward, so that the moving wheel 144 enters the sliding groove 141, thereby making the moving wheel 144 out of contact with the ground.

[0042] Through the setting of the moving part 14, when the dust reduction device needs to be moved, the base 11 can be moved on the ground by the moving wheel 144, thereby facilitating the movement of the dust reduction device; when the dust reduction device needs to work, the moving wheel 144 can be disengaged from the ground by moving the sliding plate 143 upwards, so that the base 11 is directly in contact with the ground, so that the dust reduction device is placed more stably on the ground, thereby making the subsequent dust reduction work more stable.

[0043] like Figure 4 As shown, a connecting plate 145 is fixedly connected to the upper ends of the two sliding plates 143 , and a return spring 146 is connected between the connecting plate 145 and the bottom wall of the accommodating cavity 12 .

[0044] Specifically, during use, when the sliding plate 143 moves upward, the sliding plate 143 drives the connecting plate 145 to move upward, and the connecting plate 145 stretches the reset spring 146; when the sliding plate 143 needs to be reset, the base 11 is moved upward, and the connecting plate 145 moves downward under the action of the reset spring 146, thereby driving the sliding plate 143 to reset, thereby resetting the moving wheel 144.

[0045] like Figure 4 , 5As shown in FIGS. 6, a locking member 15 is provided on the connecting plate 145. The locking member 15 includes a rod sleeve 150 fixedly connected to the bottom wall of the accommodation cavity 12. A fixing block 151 is fixedly connected to the rod sleeve 150. An opening 152 penetrating through the connecting plate 145 in the vertical direction is formed on the connecting plate 145. The fixing block 151 is located in the opening 152. Two mounting grooves 153 opening outward are symmetrically formed in the fixing block 151. A locking block 154 is slidably connected in the mounting groove 153. A compression spring 155 is connected between the locking block 154 and the mounting groove 153. A clamping groove 156 is formed on the side wall of the opening 152. The locking block 154 is inserted into the clamping groove 156.

[0046] Specifically, when in use, when the moving wheel 144 needs to move upward, the locking block 154 is moved, so that the locking block 154 compresses the compression spring 155, and the locking block 154 is removed from the clamping groove 156, thereby unlocking the connecting plate 145.

[0047] Through the arrangement of the locking member 15, the connecting plate 145 can be locked, so that the moving wheel 144 can drive the base 11 to move, facilitating the movement of the dust reduction device.

[0048] As Figure 4 、 5 As shown in FIGS. 6, the locking member 15 further includes a contact rod 157 slidably connected to the fixing block 151. The contact rod 157 extends into the mounting groove 153. The top surface of the locking block 154 is an inclined surface. The contact rod 157 can contact the inclined surface of the locking block 154. An abutting ring 158 is fixedly connected to the top end of the contact rod 157. An abutting rod 159 is slidably connected in the rod sleeve 150. The abutting rod 159 extends upward out of the through hole 13. The abutting rod 159 is in threaded fit connection with the through hole 13. A buffer spring 160 is connected between the abutting rod 159 and the rod sleeve 150. A moving rod 161 is provided on the abutting rod 159. The moving rod 161 can contact the abutting ring 158.

[0049] Specifically, when in use, when the locking member 15 needs to be unlocked, the abutting rod 159 is rotated so that the abutting rod 159 moves downward. When the abutting rod 159 moves downward, the abutting rod 159 drives the moving rod 161 to move downward. The moving rod 161 contacts the abutting ring 158, so that the abutting ring 158 moves downward. The abutting ring 158 drives the contact rod 157 to move downward. The contact rod 157 contacts the inclined surface of the locking block 154, so that the locking block 154 is removed from the clamping groove 156.

[0050] By providing the locking member 15, the unlocking of the locking member 15 can be achieved by pressing the abutting rod 159, enabling the connecting plate 145 to move, so that the moving wheel 144 can move upward and retract into the base 11, making the dust suppression work more stable.

[0051] As Figure 1 , 2 , 8, and 9 show, two stabilizing mechanisms 4 are symmetrically arranged on the base 11. The stabilizing mechanism 4 includes an extension plate 41 slidably connected to the base 11. Two sliding rods 42 are symmetrically and fixedly connected to the extension plate 41. The sliding rods 42 extend into the accommodation cavity 12, and a return spring 43 is connected between the end of the sliding rod 42 and the side wall of the accommodation cavity 12.

[0052] Specifically, during use, when the moving wheel 144 enters the accommodation cavity 12, the sliding rod 42 is moved, causing the sliding rod 42 to drive the extension plate 41 to move away from the base 11, and at the same time, the sliding rod 42 compresses the return spring 43.

[0053] By providing the extension plate 41, after the moving wheel 144 enters the accommodation cavity 12, the extension plate 41 can extend out from the base 11, enabling the extension plate 41 and the sliding rod 42 to support the base 11 and prevent the base 11 from shifting or tipping under the action of external forces.

[0054] As Figure 2 , 10 , 11 show, the stabilizing mechanism 4 further includes an oil cylinder 44 fixedly connected to the bottom wall of the accommodation cavity 12. A push rod 45 is slidably connected in the oil cylinder 44. The push rod 45 extends out of the base 11. The push rod 45 is fixedly connected to the extension plate 41. The oil cylinder 44 is connected with a connecting pipe 46. The connecting pipe 46 is communicated with the internal space of the rod sleeve 150, and hydraulic oil is provided in the rod sleeve 150.

[0055] Specifically, when the abutting rod 159 moves downward, the abutting rod 159 presses the hydraulic oil in the rod sleeve 150 into the oil cylinder 44 through the connecting pipe 46. Since the hydraulic oil in the oil cylinder 44 increases, the push rod 45 extends out of the oil cylinder 44, thereby causing the push rod 45 to drive the extension plate 41 to move away from the base 11.

[0056] By providing the oil cylinder 44, when the abutting rod 159 moves downward, the abutting rod 159 can push the hydraulic oil in the rod sleeve 150 into the oil cylinder 44, so that the push rod 45 extends out, driving the extension plate 41 to extend out, making the retraction of the moving wheel 144 and the extension of the extension plate 41 form a linkage, and making the support for the base 11 more coherent and stable.

[0057] AsFigure 4 , 7 As shown, the dust-removing mechanism 2 includes a barrel 21. One end of the barrel 21 is fixedly connected with an annular nozzle group. The nozzle group includes twenty nozzles 22 arranged along the circumferential direction. The nozzle group is communicated with a water pipe 23. A water pump 24 is arranged on the base 11. The input end of the water pump 24 is communicated with the accommodation cavity 12. Water is accommodated in the accommodation cavity 12. The output end of the water pump 24 is communicated with the water pipe 23.

[0058] Specifically, during use, when dust removal is required, the water pump 24 is started. The water pump 24 pumps the water in the accommodation cavity 12 into the water pipe 23. Then the water is sprayed out through the nozzles 22 to achieve the dust-removing work.

[0059] Through the setting of the accommodation cavity 12, water can be accommodated in the accommodation cavity 12, enabling the water pump 24 to pump out water for dust-removing work, and increasing the weight of the base 11, further improving the stability of the base 11, thereby maintaining the stability of the dust-removing work.

[0060] As Figure 4 shown, the dust-removing mechanism 2 further includes a pneumatic motor 25 fixedly connected in the barrel 21. The output end of the pneumatic motor 25 is fixedly connected with a blade 26.

[0061] Specifically, when dust removal is required, the pneumatic motor 25 is started. The pneumatic motor 25 drives the blade 26 to rotate. The blade 26 drives the air to flow and blows out the water sprayed out by the nozzles 22.

[0062] As Figure 8 shown, the connecting mechanism 3 includes two electric push rods 31 fixedly connected to the base 11. The top end of each electric push rod 31 is rotatably connected to the barrel 21. A damping member is arranged at the rotational connection of the electric push rod 31 and the barrel 21.

[0063] Specifically, during use, the electric push rods 31 are started, causing the top output ends of the electric push rods 31 to move up and down. The output ends of the electric push rods 31 drive the barrel 21 to move, adjusting the dust-removing range and angle.

[0064] Furthermore, the electric push rods 31 are of the prior art and will not be elaborated here.
