Technical Field

[0001] This utility model belongs to the field of construction engineering technology, and in particular relates to a dust suppression device for construction engineering. Background Technology

[0002] Construction projects refer to all kinds of buildings and engineering facilities that provide the material and technical foundation for human life and production. Construction projects are organized, purposeful, and large-scale economic activities. According to their natural attributes, construction projects can be divided into three categories: architectural engineering, civil engineering, and electromechanical engineering. During the construction process, a lot of smoke and dust are generated. In order to avoid smoke and dust pollution, dust suppression devices are needed to treat the smoke and dust. Most of the existing dust suppression devices are water mist dust suppression devices. However, the dust suppression range of traditional construction dust suppression devices is limited and cannot be increased according to the needs of on-site construction. This directly affects the dust suppression effect. Moreover, users need to increase the number of dust suppression devices to achieve the expected dust suppression effect, which not only increases costs but also directly reduces the overall applicability of the dust suppression devices.

It adopts an auxiliary drive component to drive a large spray head to swing back and forth in both the up-and-down and back-and-forth directions, thereby expanding the spray range of water mist. This allows the dust suppression range of the device to be increased according to the needs of on-site construction, thus directly improving the dust suppression effect and simultaneously enhancing the overall applicability of the dust suppression device, thereby solving the aforementioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A dust suppression device for construction engineering includes a trolley, on which a water tank for holding clean water is fixed, and a support column is fixed on the water tank.

[0023] Example 1: A dust suppression device for construction projects includes a trolley 1. A controller is mounted on the handle of the trolley 1. A water tank 2 for holding clean water is fixed on the trolley 1. A support column 3 is fixed on the water tank 2. A placement groove 21 is formed at the top of the support column 3. A connecting shaft 4 is rotatably mounted on the back of the inner cavity of the placement groove 21. A strip column 5 located within the placement groove 21 is fixed at one end of the connecting shaft 4. A main water pipe 10 is horizontally embedded within the strip column 5. A water pump 7 is fixed on the water tank 2, with its inlet end connected to the water tank 2 via a suction pipe. A branch pipe 8 is connected to the outlet end of the water pump 7. A fixed pipe 9 is rotatably mounted on the top of the front of the support column 3, with one end extending into the strip column 5 and connected to the main water pipe 10. One end of the branch pipe 8 is rotatably mounted on the other end of the fixed pipe 9. A top frame 6 is fixed on the strip column 5. Large spray nozzles are connected to both ends of the main water pipe 10. 11; Both the support column 3 and the top frame 6 are equipped with auxiliary drive components for use with the large spray head 11. The auxiliary drive components include an electric push rod 14 fixed to the back side of the support column 3 by a side block. The piston rod of the electric push rod 14 is fixed with a T-shaped push rod 16. The other end of the docking shaft 4 is fixed with an auxiliary frame 15 for inserting one end of the T-shaped push rod 16. The main water pipe 10 is telescopic on both sides near the strip column 5. The top of the strip column 5 is rotatably equipped with an L-shaped frame 17 whose bottom end is fixed to the outside of the top of the main water pipe 10. The L-shaped frame 17 is provided with a drive groove 24. The top of the top frame 6 is rotatably equipped with a crankshaft 18 whose bottom end is inserted into the drive groove 24. The top of the crankshaft 18 is fixed with a synchronous pulley 19 driven by a synchronous belt. The top side of the top frame 6 is fixed with a motor 20 whose output shaft end is fixed to one of the crankshafts 18 by a mounting bracket.

[0024] Specifically, this utility model, by setting up an auxiliary drive component, utilizes an electric push rod 14, a T-shaped push rod 16, and an auxiliary frame 15 to form a reciprocating up-and-down swing drive structure for the strip column 5, thereby driving the large spray head 11 to synchronously swing up and down. Furthermore, the design of the motor 20, crankshaft 18, synchronous wheel 19, L-shaped frame 17, and drive groove 24 allows the large spray head 11 to swing back and forth in the direction of forward and backward during the up-and-down swing, thereby expanding the spray range of water mist. This allows for the independent expansion of the dust suppression range of the dust suppression device according to the needs of on-site construction, thus directly improving the dust suppression effect and simultaneously enhancing the overall applicability of the dust suppression device.

[0025] Both sides of the bottom of the strip column 5 are fixed with arc-shaped slides 22, and slide seats 23 are slidably mounted on the arc-shaped slides 22. The top of the slide seats 23 is fixed to the outside of the bottom of the water main pipe 10.

[0026] Specifically, by utilizing the sliding connection between the arc-shaped slide 22 and the slide seat 23, the swingable end of the water main pipe 10 can be slidably limited, thereby improving the stability of the water main pipe 10 when it swings.

[0027] Each set of large spray heads 11 has multiple sets of evenly distributed side tubes 12 connected to its surface, and a small spray head 13 is connected to the end of the side tube 12 away from the large spray head 11.

[0028] Specifically, the design of the side pipe 12 and the small spray head 13 can expand the spray range, thereby further improving the dust suppression range and dust suppression effect, and enhancing the functionality of the device.

[0029] There is a certain gap between the bottom of the strip column 5 and the bottom of the inner cavity of the placement groove 21.

[0030] Specifically, the spacing design allows the strip column 5 to have a certain amount of vertical swing space, preventing the strip column 5 from colliding with the support column 3 when rotating, avoiding mutual interference, and improving the stability of the device during operation.

[0031] Auxiliary support plate is fixed near the top bend of branch pipe 8, and the back of the auxiliary support plate is fixed to the support column 3.

[0032] Specifically, the design of the auxiliary support plate can reinforce the branch pipe 8, improve the overall stability of the branch pipe 8, prevent the branch pipe 8 from shifting when the fixed pipe 9 rotates, and extend the service life of the branch pipe 8.

[0033] The multiple sets of small spray heads 13 all have an outward tilted structure.

[0034] Specifically, the angle of the small spray head is limited to 13 degrees to further expand the spray range, thereby further improving the dust suppression effect.

[0035] The docking shaft 4 and the fixed tube 9 are on the same longitudinal axis, and one end of the branch tube 8 is provided with a sealed bearing whose outer ring is fixed to the inner wall of the fixed tube 9.

[0036] Specifically, the design of being on the same longitudinal axis allows the docking shaft 4 and the fixed pipe 9 to rotate synchronously and stably, avoiding mutual interference. The design of the sealed bearing improves the smoothness of the rotation of the fixed pipe 9, avoids excessive friction with the branch pipe 8, and seals the contact point between the branch pipe 8 and the fixed pipe 9 to prevent leakage of clean water.

[0037] The specific usage process is as follows: The user turns on the water pump 7, electric push rod 14, and motor 20 through the controller, and presets the reciprocating stroke of the electric push rod 14. At this time, the water pump 7 can transport the clean water in the water tank 2 to the large spray head 11 through the branch pipe 8, fixed pipe 9, and main water pipe 10, and then to the small spray head 13 through multiple sets of side pipes 12. The water is then sprayed out in multiple directions through the large spray head 11 and the small spray head 13. At this time, the electric push rod 14 can drive the T-shaped push rod 16 to move up and down reciprocally. With the cooperation of the auxiliary frame 15, the docking shaft 4 can be driven to rotate back and forth, thereby driving the strip column 5 to swing up and down reciprocally, which in turn drives the large spray head 11 to swing up and down synchronously. The motor 20 is synchronized with the synchronous pulley 19. With assistance, two sets of crankshafts 18 can be driven to rotate synchronously, thereby driving the L-shaped frame 17 to swing back and forth in cooperation with the drive groove 24. Since the main water pipe 10 near the strip column 5 is a telescopic pipe structure, it can drive the large spray head 11 to swing back and forth in the up-and-down direction, expanding the spray range of the water mist, so as to independently increase the dust suppression range of the dust suppression device according to the needs of on-site construction. This utility model, by setting an auxiliary drive component, utilizes the electric push rod 14, T-shaped push rod 16, and auxiliary frame 15 to form a drive structure for the up-and-down swing of the strip column 5, thereby driving the large spray head 11 to swing synchronously up and down. The motor 20, crankshaft 18, synchronous wheel 19, L-shaped frame 17, and... The design of the drive slot 24 allows the large spray head 11 to swing back and forth during its up-and-down reciprocating motion, thereby expanding the spray range of the water mist. This allows for the independent expansion of the dust suppression range of the dust suppression device according to on-site construction needs, directly improving the dust suppression effect and simultaneously enhancing the overall applicability of the dust suppression device. The sliding connection between the arc-shaped slide 22 and the slide seat 23 allows for sliding limit of the swingable end of the main water pipe 10, improving the stability of the main water pipe 10 during swing. The design of the side pipe 12 and the small spray head 13 expands the spray range, further improving the dust suppression range and effect, and enhancing the functionality of the device. The spacing design provides the strip column 5 with sufficient space for vertical swing. To prevent the strip column 5 from colliding with the support column 3 during rotation and to avoid mutual interference, the stability of the device during operation is improved. The design of the auxiliary support plate can reinforce the branch pipe 8, improve the overall stability of the branch pipe 8, and prevent the branch pipe 8 from shifting when the fixed pipe 9 rotates, thus extending the service life of the branch pipe 8. The angle of the small spray head 13 is limited to further expand the spray range, thereby further improving the dust suppression effect. The design of being on the same longitudinal axis allows the docking shaft 4 and the fixed pipe 9 to rotate synchronously and stably, avoiding mutual interference. The design of the sealed bearing improves the smoothness of the rotation of the fixed pipe 9, avoids excessive friction with the branch pipe 8, and seals the contact point between the branch pipe 8 and the fixed pipe 9 to prevent clean water leakage.

[0038] In summary, this construction dust suppression device, by setting up an auxiliary drive component, can drive a large spray head to swing back and forth simultaneously, thereby expanding the spray range of water mist. This allows the dust suppression range of the device to be increased autonomously according to the needs of on-site construction, thus directly improving the dust suppression effect and simultaneously enhancing the overall applicability of the dust suppression device, thereby solving the aforementioned technical problems.

[0039] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
