[0002] During the current building construction process, in order to reduce dust pollution, protect the environment and the health of workers, it is very necessary to use a dust reduction device. One of the more common dust reduction methods is to atomize water through a high-pressure pump and spray it into the air. The water mist can adsorb dust particles in the air, increase their weight and cause them to settle, thereby achieving the dust reduction effect. Such dust reduction devices can be fixedly installed or used as mobile equipment according to the needs of the construction site.

[0003] The fixed dust reduction device in the related art is usually suitable for fixed-point dust reduction. Its structure mainly includes an installation frame and a water pipe fixed to the installation frame by a clamp. A plurality of sprayers are arranged at intervals on the water pipe, and the water mist sprayed by the sprayers is used to reduce dust at the construction site. For the above-mentioned fixed dust reduction device, since the installation position of the water pipe is relatively fixed, it is difficult for the staff to adjust the spraying area of the water pipe according to the actual dust reduction requirements of the construction site, which may lead to poor dust reduction effect.

[0018] The following further describes the present application in detail with reference to the drawings.

[0019] The embodiment of the present application discloses a dust reduction device for building construction.

[0020] Refer to Figure 1 、 Figure 2The dust suppression device for building construction includes a mounting frame 1 which is roughly in the shape of a rectangular frame, and a plurality of spray pipes 2 are arranged on the top of the mounting frame 1. Two horizontal cross frames 3 which are arranged perpendicular to each other are fixedly installed on the top of the mounting frame 1, and each cross frame 3 is provided with a plurality of mounting seats 4 which are arranged in sequence along the length direction of the cross frame 3. An adjustment seat 5 is rotatably provided on the top of the mounting seat 4, and a cover plate 50 is detachably installed on the top of the adjustment seat 5. Two through holes 51 for the spray pipes 2 to pass through are formed between the adjustment seat 5 and the cover plate 50, and the spray pipes 2 are respectively fixed in their respective through holes 51.

[0021] like Figure 2 , Figure 3 As shown, the adjusting seat 5 is threadedly connected with a fastener 6. In this embodiment, the fastener 6 is a long-stem bolt. The central axis of the fastener 6 is coaxially arranged with the rotation axis of the adjusting seat 5, and the fastener 6 is located between the through holes 51 on both sides. The fastener 6 is sequentially inserted into the cover plate 50 and the adjusting seat 5 from top to bottom. When the fastener 6 is tightened downward, the cover plate 50 will eventually be pressed downward on the top of the adjusting seat 5. At the same time, the spray pipe 2 inserted in the through hole 51 will be pressed and fixed on the inner wall of the through hole 51 under the limit of the cover plate 50.

[0022] like Figure 2 , Figure 3 As shown, the horizontal frame 3 is integrally formed with a limiting groove 30 on the outer side wall in the vertical direction, and the length direction of the limiting groove 30 extends along the length direction of the horizontal frame 3. The mounting seat 4 includes a limiting plate 41 whose bottom is limited in the limiting groove 30, and the limiting plate 41 is slidably arranged on the horizontal frame 3 along the length direction of the limiting groove 30, and the adjustment seat 5 slides on the horizontal frame 3 synchronously with the mounting seat 4. The mounting seat 4 is penetrated with a fixing hole 400 for the bottom of the fastener 6 to be inserted into the mounting seat 4 from top to bottom. When the fastener 6 is tightened on the adjustment seat 5, the bottom of the fastener 6 inserted into the fixing hole 400 will conflict with the top outer side wall of the horizontal frame 3. Through the mutual conflict between the fastener 6 and the horizontal frame 3, and under the limitation of the limiting plate 41, the mounting seat 4 can be limited and fixed at the specified position of the horizontal frame 3.

[0023] like Figure 2 , Figure 3 As shown, the outside of the adjustment seat 5 is coaxially sleeved with a locking plate 7 located at the top of the mounting seat 4, and a plurality of latching posts 70 are fixedly mounted on the side wall of the locking plate 7 facing the mounting seat 4, and the length direction of the latching posts 70 extends along the length direction of the fastener 6. A plurality of latching holes 40 corresponding to the latching posts 70 are arranged on the top outer side wall of the mounting seat 4, and the latching holes 40 are used for the latching posts 70 corresponding to each other to be inserted into the mounting seat 4 from top to bottom along the length direction of the rotation axis of the adjustment seat 5.

[0024] like Figure 2 , Figure 3As shown, a plurality of through holes 52 located within the mounting seat 4 penetrate through the adjustment seat 5, and the through holes 52 are evenly spaced circumferentially around the adjustment seat 5 in sequence. The pin column 70 is located on the rotation path of the through hole 52, and the through hole 52 is used for the pin column 70 to be inserted into the adjustment seat 5. Through the mutual insertion and cooperation of the pin column 70 and the through hole 52, the rotation of the adjustment seat 5 can be restricted, and the adjustment seat 5 is locked on its respective mounting seat 4.

[0025] As Figure 2 , Figure 3 shown, the adjustment seat 5 is further provided with a movable hole 53 located outside the mounting seat 4. A pressing plate 54 is movably arranged along the length direction of the fastener 6 within the movable hole 53, and the pressing plate 54 is limited within the movable hole 53. The pressing plate 54 passes through and is rotatably arranged on the fastener 6. Two limiting rings 60 are coaxially and fixedly arranged on the outside of the fastener 6. The limiting rings 60 are symmetrically arranged on both sides of the pressing plate 54, and the limiting rings 60 are in mutual contact with the outer side wall of the pressing plate 54. The pressing plate 54 rises and falls within the movable hole 53 along with the fastener 6 under the joint limitation of the two limiting rings 60 on both sides and the movable hole 53.

[0026] As Figure 2 , Figure 3 shown, both ends of the pressing plate 54 extend out of the movable hole 53 to the outside of the adjustment seat 5. After extending out, the pressing plate 54 faces the locking plate 7. When the fastener 6 is tightened downward, the pressing plate 54 is used to press the pin column 70 downward within the through hole 52. Thus, the pin column 70 is locked, ensuring the stability and reliability when the pin column 70 is inserted into the through hole 52.

[0027] As Figure 2 , Figure 3 shown, a reinforcing plate 8 is integrally formed on the bottom side wall of the cross frame 3 facing away from the spray pipe 2. The ends of adjacent reinforcing plates 8 are connected and fixed to each other by bolts and nuts. Through the reinforcing plate 8, the structural strength of the cross frame 3 can be further enhanced, improving the stability and reliability of the cross frame 3.

[0028] As Figure 1 , Figure 2 shown, a plurality of inclined struts 9 are fixedly installed between the mounting frame 1 and the cross frame 3 by bolts and nuts. One end of the inclined strut 9 is connected and fixed to the cross frame 3, and the other end of the inclined strut 9 is connected and fixed to the mounting frame 1. Through the inclined strut 9, the structural strength of the connection between the mounting frame 1 and the cross frame 3 can be further enhanced.

[0029] The implementation principle is as follows: When it is necessary to adjust the spraying area of the spray pipe 2, first unscrew the fastener 6 from the adjusting seat 5. As the fastener 6 is unscrewed upward, the bottom of the fastener 6 will be separated from the outer wall of the cross frame 3, and at this time, the locking of the mounting seat 4 is released, and the mounting seat 4 can move along the limiting groove 30 to the required position of the cross frame 3. In addition, during the process of unscrewing the fastener 6 upward, the fastener 6 will drive the pressing plate 54 to be separated from the locking plate 7. When the pressing plate 54 rises to an appropriate height along the moving hole 53, by lifting the locking plate 7 upward until the plug pin column 70 is withdrawn from the plug pin hole 40, at this time, the adjusting seat 5 can be rotated on the mounting seat 4. By turning the through hole 51 on the adjusting seat 5 to the appropriate position, it can be adapted to the installation of the spray pipe 2 in different orientations, further expanding the adjustable range. After the installation of the spray pipe 2 is completed, finally, screw the fastener 6 tightly again. Through the fastener 6, the connection and fixation of the spray pipe 2, the adjusting seat 5, and the mounting seat 4 can be realized simultaneously. The installation is convenient and fast, improving the installation efficiency and ensuring the dust reduction effect of the spray pipe 2.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
