Description

Technical Field

[0001] This utility model belongs to the technical field of dust control equipment for building engineering, and in particular relates to a dust control device for building engineering. Background Technology

[0002] Building construction is a part of construction projects, referring to the physical engineering formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines and equipment. During the construction process, dust control devices are required to block the dust generated during construction.

[0003] The existing utility model with authorization announcement number CN222879401U discloses a dust control device for construction engineering, including an outer frame, a dust control net fixed inside the outer frame, two brackets and four connecting bolts on both sides of the outer frame, two screw holes adapted to the connecting bolts on each bracket, four screw holes adapted to the connecting bolts on both sides of the outer frame, a transfer box on one side of the outer frame, and brake rollers installed at the four corners of the bottom of the transfer box.

[0004] Using the above technical solution, the guide wheels inside the transfer box facilitate the transfer of the outer frame from the ground into the transfer box, thereby saving manpower. The transfer box, brake rollers, and handrails facilitate the transfer of the outer frame. Furthermore, the insertion block on one side of the outer frame, the slot on the other side, and the locking bolts facilitate the splicing of two adjacent outer frames. However, because the dustproof net is welded to the inside of the outer frame, it is not convenient to clean the dustproof net of the dustproof device. Manual cleaning of the dust inside the mesh of the dustproof net is required. Infrequent cleaning can easily reduce the dustproof effect and breathability of the dustproof net. Moreover, it is not convenient to replace the dustproof net with severe blockage, which can further reduce the dustproof effect and breathability of the dustproof net, thereby reducing the practicality of the dustproof device.

[0005] Therefore, we propose a dust control device for building construction to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that existing technologies cannot easily clean and replace dustproof nets, and to propose a dustproof device for building engineering.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A dust control device for construction projects includes a winding drum. Two mounting rods are fixedly connected to the outer surface of the winding drum. A vacuum cleaner is fixedly connected to the ends of the two mounting rods away from the winding drum. A cleaning brush is fixedly connected to one side of the vacuum cleaner. A winding rod is rotatably connected inside the winding drum. Equally spaced circumferentially arranged limiting blocks are fixedly connected to the inner wall of the winding drum. A positioning sleeve is fitted onto the outer surface of the winding rod, and the outer surface of the positioning sleeve contacts the inner wall of the winding drum. Equally spaced circumferentially arranged... The limiting groove has several limiting blocks that are respectively engaged inside the limiting groove. A torsion spring is fixedly connected to the inner side wall of the positioning sleeve. Two retaining rings are fixedly connected to the outer surface of the winding rod. Each retaining ring is rotatably connected to the inside of the winding drum. The left side of one of the retaining rings is fixedly connected to the right end of the torsion spring. A dustproof net is fitted on the outer surface of the winding rod. The left side and right side of the dustproof net are in contact with the side of the two retaining rings that are close to each other. One side of the dustproof net is in contact with the cleaning end of the cleaning brush.

[0008] Preferably, two telescopic columns are fixedly connected to the bottom surface of the winding drum, and a support base is provided below the winding drum. Each telescopic column is slidably connected to the inside of the support base. The dustproof net is slidably connected to the inside of the two telescopic columns and the inside of the support base. Each telescopic column is fitted with a first positioning pin. The ends of the two first positioning pins that are close to each other pass through the support base and extend into the inside of the two telescopic columns.

[0009] Preferably, a clamping plate is fixedly connected to the bottom end of the dustproof net, the clamping plate is slidably connected to the inside of the support base, a second positioning pin is snapped into the inside of the dustproof net, and snapping holes are opened on both sides of the support base. One end of the second positioning pin passes through the two snapping holes, the clamping plate and the dustproof net in sequence and extends to one side of the support base.

[0010] Preferably, the bottom surface of the support base is fixedly connected to two fixed base plates, and each fixed base plate has two threaded holes on its upper surface.

[0011] Preferably, each of the fixed base plates has two reinforcing ribs fixedly connected to its upper surface, and the two sets of reinforcing ribs are respectively fixedly connected to the two sides of the support base on their respective sides.

[0012] Preferably, each set of threaded holes is internally threaded with a mounting bolt, and the bottom ends of the two sets of mounting bolts pass through the two fixed base plates and extend to the bottom of the two fixed base plates respectively.

[0013] Preferably, each set of mounting bolts has a compression spring fitted on its outer surface, and each set of compression springs has a sliding ring fixedly connected to its bottom end. The inner walls of the two sets of sliding rings are in contact with the outer surfaces of the two sets of mounting bolts, and the bottom surfaces of the two sets of sliding rings are in contact with the upper surfaces of the two fixed base plates.

[0014] Preferably, the winding drum is internally threaded with a mounting nut, the winding rod is rotatably connected to the inside of the mounting nut, and the right end of the winding rod is in contact with the inner wall of the mounting nut.

[0015] In summary, the technical effects and advantages of this utility model are as follows: By coordinating a winding drum, mounting rod, vacuum cleaner, and cleaning brush, the dustproof net can be manually pulled within the winding drum. The mounting rod and the cleaning brush, fixed to the vacuum cleaner, clean both the dustproof side of the net as it is wound onto and pulled out of the drum. This facilitates cleaning, saves manpower, and improves the dustproof effect and breathability of the net. Furthermore, the combination of the winding drum, winding rod, limiting block, positioning sleeve, limiting groove, torsion spring, retaining ring, and dustproof net allows for pre-winding of the net manually. The winding rod is wound to the outside to facilitate its placement inside the winding drum. The limiting block engages with the limiting groove on the outside of the positioning sleeve. Rotating the winding rod causes the torsion spring to rotate, accumulating elasticity and facilitating the winding of the pulled-out dustproof net. This further saves manpower. Furthermore, by cutting away the old dustproof net with a tool, a new dustproof net can be pulled out from the winding drum, making replacement easy and further improving the dustproof effect and breathability of the net.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-5 A dust control device for construction projects includes a winding drum 10. Two mounting rods 12 are fixedly connected to the outer surface of the winding drum 10. A vacuum cleaner 11 is fixedly connected to the ends of the two mounting rods 12 away from the winding drum 10. The vacuum cleaner 11 can collect and process the dust blocked by the dust control device, thereby improving the dust blocking and processing effect of the dust control device. A cleaning brush 13 is fixedly connected to one side of the vacuum cleaner 11. A winding rod 17 is rotatably connected inside the winding drum 10. A mounting nut 20 is threadedly connected inside the winding drum 10. The winding rod 17 is rotatably connected inside the mounting nut 20. The right end of the winding rod 17 contacts the inner wall of the mounting nut 20. Since the winding rod 17 rotates inside the winding drum 10, the rotation of the winding rod 17 inside the winding drum 10 is limited by the threaded mounting nut 20, thereby improving the rotation and winding stability of the winding rod 17.

[0020] The inner wall of the take-up drum 10 is fixedly connected with equidistantly arranged circumferential limit blocks 14. A positioning sleeve 15 is fitted onto the outer surface of the take-up rod 17, with the outer surface of the positioning sleeve 15 contacting the inner wall of the take-up drum 10. The outer surface of the positioning sleeve 15 has equidistantly arranged circumferential limit grooves 16. Several limit blocks 14 are respectively engaged within several limit grooves 16. A torsion spring 18 is fixedly connected to the inner wall of the positioning sleeve 15. Two retaining rings 19 are fixedly connected to the outer surface of the take-up rod 17, each retaining ring 19 being rotatably connected to the inside of the take-up drum 10. The left side of one retaining ring 19 is fixedly connected to the right end of the torsion spring 18. A dustproof net 21 is fitted onto the outer surface of the take-up rod 17, with the left and right sides of the dustproof net 21 respectively... Two retaining rings 19 are in contact with each other on their closest sides, and one side of the dustproof net 21 is in contact with the cleaning end of the cleaning brush 13. Two telescopic columns 2 are fixedly connected to the bottom surface of the take-up drum 10. A support base 1 is provided below the take-up drum 10. Each telescopic column 2 is slidably connected to the inside of the support base 1. The dustproof net 21 is slidably connected to the inside of the two telescopic columns 2 and the inside of the support base 1. A first positioning pin 3 is engaged inside each telescopic column 2. The two first positioning pins 3 are close to each other at their closest ends, respectively penetrating the support base 1 and extending into the inside of the two telescopic columns 2. By using the telescopic columns 2 to slide inside the support base 1, the dustproof height of the dustproof device can be adjusted, and the first positioning pins 3 can be used to conveniently position the telescopic columns 2 sliding inside the support base 1.

[0021] A clamping plate 22 is fixedly connected to the bottom end of the dustproof net 21. The clamping plate 22 is slidably connected to the inside of the support base 1. A second positioning pin 24 is snapped into the inside of the dustproof net 21. Snap-in holes 23 are opened on both sides of the support base 1. One end of the second positioning pin 24 passes through the two snap-in holes 23, the clamping plate 22 and the dustproof net 21 in sequence and extends to one side of the support base 1. By fixing the clamping plate 22 at the bottom end of the dustproof net 21 and by passing the second positioning pin 24 through the two snap-in holes 23, the clamping plate 22 and the dustproof net 21, the dustproof net 21 is stably installed into the inside of the support base 1.

[0022] The bottom surface of the support base 1 is fixedly connected to two fixed base plates 4. Each fixed base plate 4 has two threaded holes 6 on its upper surface. By fixing the two fixed base plates 4 under the device, it can be placed in the required position, and holes corresponding to the threaded holes 6 are drilled in that position, so that the device can be easily installed and fixed.

[0023] Two reinforcing ribs 5 are fixedly connected to the upper surface of each fixed base plate 4. The two sets of reinforcing ribs 5 are fixedly connected to the two sides of the support base 1 respectively on the side that is close to each other. The reinforcing ribs 5 are fixed at the connection between the fixed base plate 4 and the support base 1, thereby improving the connection stability between the fixed base plate 4 and the support base 1.

[0024] Each set of threaded holes 6 has a threaded connection to a mounting bolt 7. The bottom ends of the two sets of mounting bolts 7 pass through the two fixed base plates 4 and extend to the bottom of the two fixed base plates 4. By using the mounting bolts 7 to pass through the threaded holes 6 and connect with the drilled holes, the two fixed base plates 4 can be fixed on the horizontal ground, thereby allowing the dustproof device to be fixed in the required position.

[0025] Each set of mounting bolts 7 has a compression spring 8 fitted on its outer surface. Each set of compression springs 8 has a sliding ring 9 fixedly connected to its bottom end. The inner walls of the two sets of sliding rings 9 are in contact with the outer surfaces of the two sets of mounting bolts 7, and the bottom surfaces of the two sets of sliding rings 9 are in contact with the upper surfaces of the two fixed base plates 4. By manually twisting the mounting bolts 7, the sliding rings 9 are used to compress the compression springs 8, thereby using the elastic force stored in the compression springs 8 to buffer the impact force on the mounting bolts 7.

[0026] The working principle of this utility model is as follows: When using this dustproof device to block dust at a construction site, the dustproof device is first placed manually near the construction site to block dust. A hole corresponding to the threaded hole 6 is drilled at this location. An expandable connecting structure is set in the hole, allowing the mounting bolt 7 to pass through the threaded hole 6 and extend into the drilled hole. The expandable connecting structure inside is then compressed, allowing the mounting bolt 7 to be securely installed in the drilled hole. By continuing to twist the mounting bolt 7, the sliding ring 9 is compressed against the compression spring 8, allowing the compression spring 8 to accumulate elastic force. The accumulated elastic force in the compression spring 8 is used to buffer the impact force on the mounting bolt 7, thus allowing the dustproof device to be stably installed in the required position. Next, the dustproof net 21 is manually wound up between the two retaining rings 19 on the outer surface of the winding rod 17, which facilitates the installation of the dustproof net 21. The winding rod 17 is then manually fed with the dustproof net 21 into the inside of the winding drum 10. By rotating the winding rod 17, the limiting block 14 fixed inside the winding drum 10 can be engaged into the limiting groove 16 opened on the outside of the positioning sleeve 15, which restricts the rotation of the positioning sleeve 15. The mounting nut 20 is then manually installed into the inside of the winding drum 10, which facilitates the stable installation of the winding rod 17. Then, by manually pulling the dustproof net 21 outside the winding rod 17, the dustproof net 21 can be extended into the groove opened inside the support base 1 and the telescopic column 2. The clamping plate 22 is installed at the lowest end of the dustproof net 21 by manual means until the clamping plate 22 moves the dustproof net 21 into the support base 1. The second positioning pin 24 is pulled by manual means through the snap hole 23, the clamping plate 22 and the dustproof net 21 to limit the position of the dustproof net 21. At the same time, the rotating winding rod 17 can rotate the retaining ring 19, thereby twisting the torsion spring 18 to tighten it, so as to straighten the dustproof net 21 between the support base 1 and the telescopic column 2, so as to facilitate the use of the dustproof net 21 for dust prevention. When the surface of the dustproof net 21 needs to be cleaned, simply pull off the second positioning pin 24 manually to allow the dustproof net 21 to slide along the support base 1 and telescopic column 2. Then, the cleaning brush 13 fixed by the vacuum cleaner 11 and the mounting rod 12 can be used to clean the surface of the dustproof net 21. When the dustproof net 21 needs to be replaced, simply remove the clamping plate 22 at the bottom of the dustproof net 21 manually and cut off the old dustproof net 21. By pulling the dustproof net 21, the new dustproof net 21 is pulled out from the winding drum 10, thereby installing the clamping plate 22 at the bottom of the dustproof net 21 to facilitate the replacement of the dustproof net 21.
