The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] Example 1, see Figure 1-Figure 4The present embodiment provides a dust suppression device for assembled building construction, comprising an assembly box body 100, a foldable bracket 200, a side panel 300, and a foldable baffle 410. One side of the foldable bracket 200 is hinged to the assembly box body 100 and the inner wall of the side panel 300, respectively. The other side of the foldable bracket 200 is hinged to a slider 1 700 and a slider 2 500, respectively. The slider 1 700 is slidably connected to the inner wall of the side panel 300, and the slider 1 700 penetrates and is slidably connected to the assembly box body 100. The assembly box body 1 The outer side of 00 is equipped with a threaded rod 600 that can be connected to an external motor. The threaded rod 600 is threadedly connected to the thread groove opened in the slider 2 500. The end of the threaded rod 600 is connected to the motor output shaft. The thread groove on the threaded rod 600 is a bidirectional thread groove. The setting of the bidirectional thread groove of the threaded rod 600 can make the threaded rod 600 rotate in one direction and make the slider 2 500 move up and down in a cycle. The two sides of the folding baffle 410 are fixed with connecting rods 430. The top of the connecting rod 430 on the right side is fixed with a top The cover 420, the two connecting rods 430 are respectively rotatably connected to the inner wall of the assembly box body 100 and the side plate 300, the front ends of the two connecting rods 430 are fixed with small gears 440, the assembly box body 100 and the side plate 300 are fixed with two-way hydraulic chambers 450, one end of the two two-way hydraulic chambers 450 is piston-slidingly connected to a vertical hydraulic rod 460, and the other end of the two two-way hydraulic chambers 450 is piston-slidingly connected to a gear hydraulic rod 470, the gear hydraulic rod 470 and The small gear 440 is engaged, and the gear hydraulic rod 470 is an arc-shaped structure. In the initial state, the end of the gear hydraulic rod 470 is engaged with the small gear 440. This design can prevent the gear hydraulic rod 470 from causing motion interference with nearby structures when it moves. The top of the assembly box body 100 is provided with an opening 1 that is compatible with the top cover 420, and the side of the assembly box body 100 is provided with an opening 2 that is compatible with the side panel 300. The front end of the assembly box body 100 is equipped with a dust suppression component 900 through a pipe bracket 800. The folding baffle 410 is unfolded by the folding bracket 200. At the same time, the folding baffle 410 can be flipped during the unfolding process to block the dust suppression component 900. This can not only prevent falling objects from high altitudes on the construction site, but also provide a sunshade in hot weather.

[0042] When the above-mentioned device is used, the assembly box body 100 is first installed in the construction site by bolts, and then the threaded rod 600 is connected to a motor, and the dust suppression component 900 is connected to a spray water pump. Then the motor is started to control the threaded rod 600 to rotate. At this time, as the threaded rod 600 rotates, the slider 2 500 threadedly connected thereto slides. As the slider 2 500 slides, the folding bracket 200 hinged thereto slowly unfolds. At the same time, the slider 1 700 hinged to the folding bracket 200 slides on the inside of the side panel 300. When the folding bracket 200 is fully unfolded, the folding baffle 410 will be fully unfolded. At the same time, when the slide When block 1 700 and slider 2 500 slide to the end, they will squeeze the two vertical hydraulic rods 460 in the two two-way hydraulic chambers 450 at the same time. At this time, under the action of liquid pressure, the two gear hydraulic rods 470 will be pushed out synchronously. As the two gear hydraulic rods 470 are extended, the two small gears 440 will be pushed to rotate at the same time, and then the two connecting rods 430 will be driven to rotate synchronously, so that the folding baffle 410 fixed between the two connecting rods 430 will flip over, and the top cover 420 will follow the flip to cover the top of the dust reduction component 900, and then the dust reduction component 900 will be supplied with water through the spray water pump to perform spray dust reduction operations.

[0043] Example 2, see Figure 1 、 Figure 5 、 Figure 6 Based on the first embodiment, the dust suppression assembly 900 includes a telescopic spray pipe 910 and a support plate 970. The telescopic spray pipe 910 is rotatably connected to the inside of the pipe bracket 800. The extended end of the telescopic spray pipe 910 is rotatably connected to the inner wall of the support plate 970. The support plate 970 is fixedly connected to the side plate 300. The dust suppression assembly 900 also includes a ring gear 920 fixed to the outside of the telescopic spray pipe 910 and a support rod 930 fixed to the side of the pipe bracket 800. The bottom of the support rod 930 is hinged with a reset plate 940. An annular spring piece 950 is fixed between the reset plate 940 and the support rod 930. The front end of the support rod 930 passes through and is slidably connected to a rack rod 960. The rack rod 960 meshes with the ring gear 920. The top of the rack rod 960 is an arc-shaped structure. The bottom of the rack rod 960 is rotatably connected to a ball bearing. The top of the rack rod 960 is located on the motion trajectory of the top cover 420. By setting up a dust reduction component 900 with adjustable angle, during the installation process, the nozzle of the telescopic spray pipe 910 is facing upward to prevent water overflow. At the same time, after it is installed and unfolded, the nozzle of the telescopic spray pipe 910 will face the position of forty-five degrees diagonally downward, which can better improve the dust reduction effect.

[0044] When the above-mentioned device is used in practice, based on the first embodiment, as the side panel 300 moves and unfolds, the telescopic spray pipe 910 will be driven to unfold through the support plate 970. When the top cover 420 is flipped over, the upper end of the rack rod 960 will be squeezed to move downward. The movement of the rack rod 960 will drive the telescopic spray pipe 910 to rotate through the ring gear 920 engaged therewith, so that the spraying direction is inclined downward by forty-five degrees, which can better improve the dust reduction effect. At the same time, as the rack rod 960 moves downward, the reset plate 940 will be squeezed to rotate, and then the annular spring piece 950 will be squeezed to be in a compressed state. When the device returns to its initial state, the device can be reset by its rebound force.

[0045] Example 3, see Figure 2 、 Figure 7-Figure 9 On the basis of the first embodiment, the bottom of the assembly box body 100 is provided with a special-shaped groove, and the assembly box body 100 is equipped with a lifting component 1000 through the special-shaped groove at the bottom thereof, and the lifting component 1000 includes a five-way hydraulic tank 1010 and a lifting plate 1020. The five-way hydraulic tank 1010 is fixed in the special-shaped groove, and one end of the interior of the five-way hydraulic tank 1010 is penetrated and the piston is slidably connected to a hydraulic rod 1030, and the interior of the five-way hydraulic tank 1010 is also connected to the lifting plate 1020. The four outer ports are all connected to a hydraulic rod 2 1040 in a piston sliding manner. The lifting plate 1020 is hinged in the special-shaped groove. There are four lifting plates 1020 in total. Each lifting plate 1020 is equipped with a torsion spring 1060 at its hinge. The bottom of each lifting plate 1020 is hinged with a rubber pad 1050. The four hydraulic rods 2 1040 are respectively adapted to the four lifting plates 1020. The end of the hydraulic rod 2 1040 close to the lifting plate 1020 is a sloped structure. By setting up the lifting assembly 1000, the entire equipment can be separated from the transport carrier during transportation, preventing the vibration generated by the transport carrier from being directly transmitted to the interior of the equipment, thereby achieving a shock absorption and protective effect.

[0046] When the above-mentioned device is used in practice, during transportation, in order to prevent the device from being placed directly on the transport carrier and the vibration generated during transportation being directly transmitted to the device body, when the side plate 300 moves and fits with the assembly box body 100, the hydraulic rod 1 1030 will be squeezed. At this time, the liquid pressure in the five-way hydraulic warehouse 1010 becomes large, and then the four hydraulic rods 2 1040 are pushed out at the same time. Since the four hydraulic rods 2 1040 are respectively adapted to the four lifting plates 1020, and the end of the hydraulic rod 2 1040 close to the lifting plate 1020 is an inclined structure, it will push the lifting plate 1020 to rotate downward, lift the assembly box body 100 off the ground, and make it leave the ground. The rubber pad 1050 at the bottom of the lifting plate 1020 contacts the ground or the transport carrier. During transportation, the device can be separated from the transport carrier as a whole, preventing the vibration generated by the transport carrier from being directly transmitted to the inside of the device, thereby achieving a shock absorption and protection effect.

[0047] At the same time, the setting of the torsion spring 1060 can not only assist in shock absorption, but also reset the lifting plate 1020.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
