Description

Technical Field

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

[0002] Most of the existing construction sites will generate a large amount of dust during construction, resulting in a high content of dust and other impurity particles in the air near the construction site, which greatly reduces the environmental quality around the construction site. Therefore, according to environmental protection requirements, it is necessary to fence and reduce dust around the construction site.

[0003] Most of the existing dust reduction methods are spray dust reduction, that is, an atomizing nozzle is installed at the enclosure, and the water is pressurized and transported to the atomizing nozzle through the water supply pipe, and then sprayed out, and the atomizing dust reduction operation is continuously performed near the enclosure to reduce the impact on the quality of the surrounding environment of the construction site. However, this dust reduction method usually involves tying a water supply pipe equipped with multiple atomizing nozzles to the upper end of the enclosure, and the length of the nozzle is set and extended along the length direction of the enclosure. Since the length direction of the water supply pipe is fixed along the distribution direction of the enclosure, the distance at which the atomizing nozzle on the water supply pipe sprays water is fixed, and the dust reduction area that can be used is also fixed and limited, resulting in a small dust reduction area and poor dust reduction effect, so further improvement is needed. Summary of the invention

[0004] In order to improve the dust reduction effect, the present application provides a construction dust reduction device.

[0005] The present application provides a construction dust reduction device, which adopts the following technical solution: A dust reduction device for construction includes an enclosure, a first water spray pipe arranged on the top of the enclosure, a first nozzle arranged on the first water spray pipe, a rotating frame rotatably connected to the enclosure for installation of the first water spray pipe, a water supply mechanism for supplying water to the first water spray pipe, and a driving mechanism for driving the rotating frame to rotate; a plurality of rotating frames are arranged at intervals along the length direction of the enclosure, the number of the first water spray pipes corresponds to the number of rotating frames, a plurality of first nozzles are arranged at intervals along the length direction of the first water spray pipes, and a plane formed by the first water spray pipe as the rotating frame rotates is parallel to the plate surface of the enclosure.

[0006] By adopting the above technical solution, the driving mechanism is used to drive the rotating frame to rotate forward or reverse, so as to realize the adjustment of the spraying position of the first nozzle at different height positions and horizontal positions. Compared with the fixed position spraying of the first nozzle in the prior art, the dust reduction range is effectively expanded, the dust reduction effect is improved, and the flexibility and coverage of the spraying area are further ensured, which solves the problem of small dust reduction area caused by traditional fixed water spray pipes.

[0007] Preferably, the driving mechanism includes a traction rope, a ring arranged on the first water spray pipe for the traction rope to be passed through, a driving component connected to one end of the traction rope for winding or unwinding, and a reset component for driving the rotating frame to reset. A first water hose is connected between adjacent first water spray pipes, one traction rope corresponds to one enclosure or multiple enclosures, at least two rings are arranged on one first water spray pipe, one traction rope is passed through the rings on several first water spray pipes, and one end of the traction rope away from the driving component is fixedly connected to the enclosure.

[0008] By adopting the above technical solution, the traction rope passes through the ring provided on the first water spray pipe, and one end of the traction rope is reeled or unreeled through the driving component, thereby driving the first water spray pipe and the first nozzle thereon to move. This design effectively expands the working coverage of the first nozzle, so that the dust reduction area is no longer limited to fixed points, realizes a wider range of spatial dust reduction treatment, and significantly improves the dust reduction efficiency and effect during the entire construction process. At the same time, one traction rope can be used for one or more enclosures, which enhances the applicability and economy of the device. In addition, the design of at least two rings on each first water spray pipe further ensures that the force is uniform and stable during the traction process, and improves the reliability of system operation.

[0009] Preferably, the traction rope includes a threading section arranged parallel to the length direction of the first water spray pipe, a first connecting section connected to two adjacent threading sections, a second connecting section for connecting to the enclosure, and a third connecting section for connecting to the driving assembly, and both ends of the threading section are respectively threaded through the two threading rings.

[0010] By adopting the above technical solution, the traction rope consists of a threading section, a first connecting section, a second connecting section and a third connecting section, wherein the threading section is arranged parallel to the length direction of the first water spray pipe to ensure the stability of the traction force transmission; the first connecting section connects two adjacent threading sections to form a continuous structure of the traction rope to adapt to the layout requirements of multiple first water spray pipes; the second connecting section is used to connect with the enclosure to ensure the fixity of the traction system; the third connecting section is connected to the driving assembly to realize power input for the entire traction process.

[0011] It should be noted that for the initial position of the first water spray pipe under the reset assembly, with the traction of the traction rope, the first water spray pipe can rotate within the angle range of 0-180 degrees. Since the first nozzle is arranged on the first water spray pipe, when it rotates 180 degrees, the coverage area is the widest and the dust reduction area is the largest.

[0012] Preferably, the driving assembly includes an installation box connected to the traction rope, a first gear built into the installation box, two first racks respectively arranged on the top wall and bottom wall of the installation box to engage with the first gear, and a first driving motor driving the first gear to rotate, and the first gear is an incomplete gear.

[0013] By adopting the above technical solution, by using the cooperation between the incomplete first gear and the two first racks, the first drive motor can drive the first gear to rotate in the same direction, so as to achieve the intermittent winding and unwinding action of the traction rope. This design makes the movement of the traction rope more precise and controllable, thereby effectively adjusting the position of the first water spray pipe, and further optimizing the spray range and dust reduction effect of the first nozzle. And compared with directly rotating the first drive motor forward or reverse, this design has relatively low wear on the first drive motor.

[0014] Preferably, the first nozzle is a hollow cone nozzle, the hollow cone nozzle has a built-in second nozzle, the second nozzle is an atomizing nozzle, several atomizing nozzles are connected to a second water spray pipe, the diameter of the second water spray pipe is smaller than the diameter of the first water spray pipe, the length direction of the second water spray pipe is parallel to the length direction of the first water spray pipe, and two adjacent second water spray pipes are connected to a second water supply hose.

[0015] By adopting the above technical scheme, the setting of the hollow cone nozzle can expand the spraying range of a single first nozzle and increase the dust reduction coverage area; the design of the built-in atomizing nozzle helps to improve the atomization effect of water and supplement the range that the hollow cone nozzle cannot cover, thereby enhancing the dust reduction ability; the introduction of the second water spray pipe realizes the separate water supply to the atomizing nozzle, avoiding the influence of insufficient pressure of the first water spray pipe on the atomization effect; the smaller diameter design of the second water spray pipe can reduce water waste while ensuring smooth water flow; the parallel arrangement of the second water spray pipe and the first water spray pipe and the connection of the first water supply hose ensure the compactness and flexibility of the overall structure, and further improve the working efficiency and applicability of the dust reduction device.

[0016] Preferably, the first water spray pipe includes a first tube, two second tubes respectively slidably sleeved on the first tube and a spring arranged between the two second tubes, the two ends of the spring are respectively connected to the second tubes at the two ends, and the spring forces the two second tubes to move away from each other; the first nozzle is arranged on the second tube, and a first guide plate is arranged on the enclosure, two first guide plates are provided and symmetrically arranged along the axis of the rotating frame, and both of the two second tubes are protruding with abutment rods for abutting against the first guide plates, and an adjustment mechanism is provided on the enclosure for adjusting the distance between the two first guide plates.

[0017] By adopting the above technical solution, the first water spray pipe is composed of a first pipe and two second pipes slidably sleeved on the first pipe, and the second pipes at both ends are connected by springs, so that the two second pipes are separated from each other without external force. At the same time, two first guide plates symmetrically distributed along the axis of the rotating frame are arranged on the enclosure, so that when the driving mechanism drives the water spray pipe to rotate, due to the abutment between the abutment rod arranged on the water spray pipe and the first guide plate, the length of the water spray pipe during the rotation of the driven mechanism is changed, thereby changing the spray position of the nozzle. And in conjunction with the adjustment mechanism, the distance between the two first guide plates can be accurately adjusted according to actual needs to further optimize the position state of the first water spray pipe, so that the range of the nozzle spray is used to adapt to a large range but a small dust height, or a small range but a high dust height area, so that the spray range of the corresponding first nozzle can be adjusted according to the actual situation to ensure that the first nozzle covers the best dust reduction area, and finally achieve the purpose of enhancing the applicability of the equipment and improving the dust reduction efficiency.

[0018] Preferably, the first guide plate is an arc-shaped plate, and the axis of the arc-shaped plate is located between two arc-shaped plates.

[0019] By adopting the above technical solution, the first guide plate is set as an arc-shaped plate, which can guide the abutment rod on the first pipe to move along the arc path of the arc-shaped plate, so that the first water spray pipe can achieve a smoother expansion or contraction action during the rotation process.

[0020] Preferably, the adjustment mechanism includes a connecting rod connecting the two first guide plates, a mounting frame provided on the enclosure for rotational connection of the connecting rod, and a control component for controlling the rotation angle of the connecting rod.

[0021] By adopting the above technical solution, a connecting rod connects the two first guide plates, the mounting frame provides a rotation support point for the connecting rod, and the control component accurately adjusts the rotation angle of the connecting rod to different angles, so as to realize flexible adjustment of the distance between the two first guide plates in the vertical direction relative to the rotation point of the first water spray pipe, so as to better adapt to different dust reduction scenarios.

[0022] At the same time, by adjusting the spacing between the first guide plates, the telescopic state of the first water spray pipe can be further optimized to ensure that the coverage of the first nozzle is wider and more uniform, thereby effectively improving the dust reduction effect.

[0023] Preferably, the control assembly includes a control plate arranged on the mounting frame and bolts passing through the control plate, the mounting frame includes a second fixed plate connected to the enclosure and a second rotating shaft rotatably passing through the second fixed plate, the second rotating shaft is connected to the connecting rod, the second rotating shaft is fixedly connected to the control plate, the control plate is penetrated by a through hole for the bolt to pass through, a plurality of the through holes are arranged at intervals around the axis of the control plate, and the bolts are threadedly connected to the mounting frame.

[0024] By adopting the above technical solution, according to the dust situation on site, the control plate is used to rotate to change the angle formed between the length direction of the first guide plate and the length direction of the enclosure. When it is rotated to the corresponding required position, the bolts are passed through the holes on the control plate to be threadedly connected with the mounting frame to fix the angle of the first guide plate at this time, and the spacing between the two first guide plates is adjusted by driving the connecting rod. This design not only improves the convenience of operation during the adjustment process, but also ensures that the first water spray pipe can flexibly adapt to different dust reduction requirements during operation, enhancing the dust reduction effect while ensuring the stability of equipment operation.

[0025] Preferably, the control assembly includes a second gear disposed on the mounting frame, a second rack meshed with the second gear, and a driving member for driving the second rack to slide along the length direction of the enclosure.

[0026] By adopting the above technical solution, the meshing transmission of the second gear and the second rack enables the connecting rod to rotate when the driving member pushes the second rack to slide, thereby adjusting the position of the first guide plate. This design not only simplifies the operation process, but also improves the adjustment accuracy, further optimizes the telescopic range of the water spray pipe, and indirectly improves the dust reduction coverage area and effect.

[0027] In summary, this application has the following beneficial effects: 1. By setting up a rotating frame and a driving mechanism, the first water spray pipe and the first nozzle thereon can be driven to adjust at different heights and horizontal positions, which effectively expands the coverage of the first nozzle, solves the problem of limited area of ​​traditional fixed spray dust reduction, and significantly improves the dust reduction effect; 2. Through the cooperation of the incomplete first gear and the two first racks, the first drive motor can drive the first gear to rotate in the same direction, so as to achieve intermittent winding and unwinding of the traction rope. This design makes the movement of the traction rope more precise and controllable, thereby effectively adjusting the position of the first water spray pipe and further optimizing the spray range and dust reduction effect of the first nozzle.

[0028] 3. By providing an adjustment mechanism, the distance between the two first guide plates can be accurately controlled according to actual needs to further optimize the position of the first water spray pipe, so that the spray range of the nozzle can be adapted to a large area with a small dust height, or a small area with a high dust height. Therefore, the spray range of the corresponding first nozzle can be adjusted according to actual conditions to ensure that the first nozzle covers the best dust reduction area, thereby ultimately achieving the purpose of enhancing the applicability of the equipment and improving the dust reduction efficiency.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-10 , further details of this application are given.

[0032] The embodiment of the present application discloses a dust reduction device for construction.

[0033] Embodiment 1: A dust suppression device for construction, referring to Figure 1 , Figure 2 , including an enclosure 1, a first water spray pipe 2 arranged on the top of the enclosure 1, a first nozzle 3 arranged on the first water spray pipe 2, a rotating frame 4 rotatably connected to the enclosure 1 for installing the first water spray pipe 2, a water supply mechanism 5 for supplying water to the first water spray pipe 2, and a driving mechanism 6 for driving the rotating frame 4 to rotate.

[0034] There are a number of rotating frames 4 arranged at intervals along the length direction of the enclosure 1 , and the number of the first water spray pipes 2 corresponds to the number of the rotating frames 4 .

[0035] Reference Figure 2 , Figure 3The rotating frame 4 specifically includes a first fixed plate 41 fixedly connected to the upper surface of the enclosure 1, a first rotating shaft 42 rotatably connected to the first fixed plate 41, and a connecting head 43 fixedly connected to the first rotating shaft 42. The length direction of the first fixed plate 41 is parallel to the height direction of the enclosure 1, and the length direction of the first rotating shaft 42 is parallel to the thickness direction of the enclosure 1. The connecting head 43 is fixedly connected to the middle part of the first water spray pipe 2, and the length direction of the first water spray pipe 2 is perpendicular to the length direction of the first rotating shaft 42. Among them, the first nozzle 3 can be a hollow cone nozzle or other nozzles such as an atomizing nozzle, which is specifically set according to needs. Several first nozzles 3 are arranged at intervals along the length direction of the first water spray pipe 2. In this embodiment, two first nozzles 3 are shown, and the two first nozzles 3 are respectively arranged at both ends of the first water spray pipe 2.

[0036] Among them, a first water supply hose 21 is connected between adjacent first water spray pipes 2 to reduce the number of water supply mechanisms 5. Due to the rotation of the rotating frame 4, the first water spray pipe 2 will also rotate accordingly. The first water supply hose 21 is set so that the first water spray pipe 2 can rotate with the rotating frame 4.

[0037] Back to Figure 1 The water supply mechanism 5 specifically includes a water supply pipe 51 connected to one of the first water spray pipes 2 or the first water supply hose 21, a control water pump 52 arranged on the water supply pipe 51, and a water tank 53 connected to the water inlet end of the control water pump 52.

[0038] Reference Figure 2 , Figure 4 In this embodiment, the driving mechanism 6 specifically includes a traction rope 61, a ring 62 provided on the first water spray pipe 2 for the traction rope 61 to pass through, a driving component 63 connected to one end of the traction rope 61 for winding or unwinding, and a reset component 64 for driving the rotating frame 4 to reset. At least two rings 62 are provided on one first water spray pipe 2, and the two rings 62 are provided between the two first nozzles 3. One traction rope 61 passes through several rings 62 on the first water spray pipe 2, so that one traction rope 61 corresponds to one enclosure 1 or multiple enclosures 1, and one end of the traction rope 61 away from the driving component 63 is fixedly connected to the enclosure 1.

[0039] For the traction rope 61, specifically, the traction rope 61 includes a threading section 611 arranged parallel to the length direction of the first water spray pipe 2, a first connecting section 612 connected to two adjacent threading sections 611, a second connecting section 613 for connecting to the enclosure 1 and a third connecting section 614 for connecting to the driving assembly 63, and the threading section 611 is passed through two rings 62.

[0040] It should be noted that, with respect to the shape setting of the traction rope 61, specifically, the two ends of the first water spray pipe 2 are respectively the first end and the second end. In this regard, with respect to the connection between the first connecting section 612 and the penetration section 611, the two ends of the first connecting section 612 can extend to the first end (second end) of two adjacent first water spray pipes 2; or one end of the first connecting section 612 is extended to the first end of one of the first water spray pipes 2, and the other end of the first connecting section 612 is extended to the second end of the other first water spray pipe 2. Under the action of the initial reset component 64, the traction rope 61 is set in a broken line.

[0041] The driving component 63 specifically includes an installation box 631 connected to the traction rope 61, a first gear 632 built into the installation box 631, two first racks 633 respectively arranged on the top wall and the bottom wall of the installation box 631 to mesh with the first gear 632, and a first driving motor 634 that drives the first gear 632 to rotate. The installation box 631 is slidably connected to the enclosure 1. In this embodiment, the first gear 632 is an incomplete gear, and the enclosure 1 protrudes with a mounting plate 11 for installing the first driving motor 634, and the output shaft of the first driving motor 634 rotates and passes through the mounting plate 11.

[0042] Reference Figure 3 In this embodiment, the reset component 64 is specifically a torsion spring, which is coaxially sleeved on the first rotating shaft 42. A mounting ring 421 is fixedly sleeved on the first rotating shaft 42. Both ends of the torsion spring are respectively fixedly connected to the surfaces of the first fixing plate 41 and the mounting ring 421 that are close to each other.

[0043] It should be noted that, since the driving mechanism 6 is used to drive the rotating frame 4 to rotate, so that the plane formed by the first water spray pipe 2 as the rotating frame 4 rotates is parallel to the plate surface of the enclosure 1. For the rotation of the rotating frame 4, the driving mechanism 6 can also be a separate driving motor, the driving motor is fixedly connected to the first fixed plate 41, and the output shaft of the driving motor is fixedly connected to the first rotating shaft 42. Start the driving motor to drive the first rotating shaft 42 to rotate, so as to change the height position and horizontal position of the first nozzle 3 on the first water spray pipe 2, that is, change the spray range of the first nozzle 3. It should be noted that, since the first water delivery hose 21 is provided, the selected driving motor needs to be able to realize forward and reverse rotation.

[0044] Since a driving motor is provided to drive the first rotating shaft 42, the number of driving motors provided is relatively large, and the cost is relatively large. In this regard, the driving mechanism 6 may also include a rack provided along the length direction of the enclosure 1, a driving gear and a driven gear meshed with the rack, and a driving motor driving the driving gear to rotate. The first rotating shaft 42 is fixedly penetrated through the driven gear. With the forward or reverse rotation of the driving motor, the rack is driven to slide back and forth along the length direction of the enclosure 1 to drive the first water spray pipe 2 to reciprocate. However, the above two driving mechanisms 6 are relatively more expensive than the traction rope 61, and can be specifically set according to the environment and needs.

[0045] The implementation principle of a construction dust reduction device in the embodiment of the present application is as follows: by utilizing the cooperation between the incomplete first gear 632 and the two first racks 633, the first drive motor 634 can drive the first gear 632 to rotate in the same direction, thereby realizing the intermittent winding and unwinding action of the traction rope 61. Since the traction rope 61 passes through the ring 62 set on the first water spray pipe 2, the first water spray pipe 2 and the first nozzle 3 thereon are driven to move. Thereby, the spray position adjustment of the first nozzle 3 at different height positions and horizontal positions is realized. Compared with the fixed position spraying of the first nozzle 3 in the prior art, the dust reduction range is effectively expanded, the dust reduction effect is improved, the flexibility and coverage of the spraying area are further ensured, and the problem of small dust reduction area caused by the traditional fixed water spray pipe is solved.

[0047] Among them, the setting of the hollow cone nozzle can expand the spraying range of the single first nozzle 3 and increase the dust reduction coverage area; the design of the built-in atomizing nozzle helps to improve the atomization effect of water and supplement the range that the hollow cone nozzle cannot cover, thereby enhancing the dust reduction ability and further improving the working efficiency and applicability of the dust reduction device.

[0048] Embodiment 3: Reference Figure 6 , Figure 7 , which is different from the embodiment 1, is that the first water spray pipe 2 includes a first pipe 22, two second pipes 23 respectively slidably sleeved on the first pipe 22, and a spring 24 arranged between the two second pipes 23. At this time, the first spray head 3 is arranged on the second pipe 23, and the connector 43 is connected to the first pipe 22, or the first pipe 22 is directly connected to the first rotating shaft 42. The two ends of the spring 24 are respectively connected to the second pipes 23 at the two ends, and a plurality of springs 24 are arranged at intervals around the axis of the first pipe 22, and the springs 24 force the two second pipes 23 to move in a direction away from each other.

[0049] In this embodiment, a first guide plate 7 is provided on the enclosure 1, two first guide plates 7 are provided and are symmetrically arranged along the axis of the rotating frame 4, the length of the first guide plate 7 is longer than the distance between the two first guide plates 7, and the two second tubes 23 both protrude with abutment rods 25 for abutting against the first guide plates 7, and an adjustment mechanism 8 for adjusting the distance between the two first guide plates 7 is provided on the enclosure 1.

[0050] In this embodiment, the adjustment mechanism 8 specifically includes a connecting rod 81 connecting the two first guide plates 7, a mounting frame 82 provided on the enclosure 1 for the connecting rod 81 to be rotatably connected, and a control assembly 83 for controlling the rotation angle of the connecting rod 81. Among them, the mounting frame 82 includes a second fixed plate 821 provided on the enclosure 1 and a second rotating shaft 822 rotatably connected to the second fixed plate 821. The second rotating shaft 822 is a sleeve arrangement. The second rotating shaft 822 is coaxially sleeved on the first rotating shaft 42, and a gap is left between the second rotating shaft 822 and the first rotating shaft 42. In order to reduce the influence on the rotation of the first rotating shaft 42, the second rotating shaft 822 and the connecting rod 81 are fixedly connected.

[0051] Among them, the control component 83 specifically includes a control plate 831 arranged on the mounting frame 82 and a bolt 832 passing through the control plate 831, the second rotating shaft 822 is fixedly connected to the control plate 831, and the control plate 831 is penetrated by a through hole 833 for the bolt 832 to pass through. A plurality of through holes 833 are arranged at intervals around the axis of the control plate 831, and the second fixed plate 821 is provided with a threaded hole for the bolt 832 to be threadedly connected.

[0052] Two first guide plates 7 are symmetrically distributed along the axis of the rotating frame 4 on the enclosure 1, so that when the driving mechanism 6 drives the first water spray pipe 2 to rotate, the length of the first water spray pipe 2 during the rotation of the driving mechanism 6 is changed, thereby changing the spraying position of the first nozzle 3. In conjunction with the adjustment mechanism 8, the distance between the two first guide plates 7 can be accurately adjusted according to actual needs to further optimize the position state of the first water spray pipe 2, so as to ensure that the first nozzle 3 covers the best dust reduction area, and finally achieve the purpose of enhancing the applicability of the equipment and improving the dust reduction efficiency.

[0053] Embodiment 4: Reference Figure 8 , which is different from the embodiment 3, is that in this embodiment, the control assembly 83 includes a second gear 834 connected and coaxially sleeved on the second rotating shaft 822, a second rack 835 meshing with the second gear 834, and a driving member for driving the second rack 835 to slide along the length direction of the enclosure 1. The number of the second gears 834 is set corresponding to the number of the connecting rods 81, and the second rack 835 is slidably connected to the enclosure 1.

[0054] In this embodiment, the driving member can be an electric push rod fixedly connected to one end of the second rack 835, or the driving member includes a driving gear meshed with the second rack 835 and a second driving motor that drives the driving gear to rotate. The second driving motor is installed on the enclosure 1 and is specifically set according to needs.

[0055] The driving member is started to change the rotation angle of the first guide plates 7, which simplifies the operation process, improves the adjustment accuracy, further optimizes the telescopic range of the first water spray pipe 2, and indirectly improves the dust reduction coverage area and effect.

The spraying range of the nozzle can be adjusted according to the needs to adapt to a large range with a small dust height, or a small range with a high dust height, so that the spraying range of the corresponding first nozzle 3 can be adjusted according to the actual situation to ensure that the first nozzle 3 covers the best dust reduction area, and finally achieve the purpose of enhancing the applicability of the equipment and improving the dust reduction efficiency.

[0057] Furthermore, Fig.10 As shown, the first guide plate 7 is an arc-shaped plate, the axis of the arc-shaped plate is located between the two arc-shaped plates, and the second guide plate 71 is also an arc-shaped plate, so that the guide frame is an elliptical frame. The abutment rod 25 on the second pipe 23 can be guided to move along an arc path, so that the first water spray pipe 2 can achieve a more stable expansion or contraction action during the rotation process.
