[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. A building refers to a project with a roof, beams, columns, walls, foundations and internal space that can meet people's needs for production, residence, study and public activities. During the construction process, a lot of dust will be generated. In order to reduce the impact of dust on the environment and human body, construction engineering dust reduction devices are usually used to reduce dust.

[0003] After searching, it is found in the patent publication number CN220677227U that a conveniently adjustable dust suppression device for construction is proposed that "the utility model is driven by an electric cylinder through a transmission sleeve and a moving plate to move the slide bar to a suitable position, and then the motor and the reciprocating screw drive the gear sleeve to swing back and forth through the moving plate and the slide bar, and finally the gear sleeve drives the dust suppression fog cannon to swing and spray through the gear rod, so as to achieve the advantage of convenient adjustment of the spray range, a large spray area, and thus improve the dust suppression effect";

[0004] However, the above scheme still has certain shortcomings in actual use. In this scheme, the dust reduction fog cannon is pushed to the position where dust reduction is required by driving the base through the roller, but no positioning measures are set in this scheme, resulting in that after the device is moved to the specified position, it cannot be fixed at the current position, which makes the device prone to self-sliding, so that the device may collide with other objects and even pose a threat to the life safety of the staff.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model discloses a dust reduction device for construction, comprising a mobile structure 1, a dust reduction device 2 is arranged at the top of the mobile structure 1, and a positioning structure 3 is arranged at the bottom of the mobile structure 1; the mobile structure 1 comprises a mobile base 101, both sides of the mobile base 101 are provided with driving crawler structures 102, and the bottom of the mobile base 101 is provided with two mounting recesses 103; the dust reduction device 2 comprises a water storage tank 201, a fog cannon 202 and an adjusting bracket 203, the fog cannon 202 is hinged to the top of the mobile base 101 through the adjusting bracket 203, and the water storage tank 201 is connected to the fog cannon 202 through an extraction pump.

[0021] The positioning structure 3 includes a drive box 301, which is fixedly installed on the inner wall of the installation recess 103. The side end of the drive box 301 is fixedly connected to a side plate 302. The outer side of the side plate 302 is connected to a driving gear 303 through an external motor. A follower gear 304 is meshed above the driving gear 303. The back side of the follower gear 304 extends to the inside of the drive box 301 and is fixedly connected to a gear shaft 305. Two racks 306 are meshed on the outer side of the gear shaft 305. The bottom ends of the two racks 306 extend to the bottom of the drive box 301, and a contact plate 307 is fixedly installed between the bottom ends of the two racks 306.

[0022] By setting up the positioning structure 3, the active gear 303 is used to drive the gear shaft 305 to drive the rack 306 to engage with each other through the follower gear 304, so that the rack 306 can drive the contact plate 307 along the surface of the slide bar 311 to adjust the height, so that the contact plate 307 gradually contacts the ground, and the contact plate 307 gradually lifts the driving track structure 102 off the ground, so that the mobile base 101 switches from the movable mode to the positioning mode, so that the dust reduction device can be fixed at the current position under the restriction of the contact plate 307, thereby avoiding the situation in which the device in the comparative scheme is prone to self-sliding, making the use of the dust reduction device safer.

[0023] Specifically, an inspection cover 308 is hingedly connected to the outer side of the side plate 302 , and the driving gear 303 and the driven gear 304 are both located inside a cavity formed between the inspection cover 308 and the side plate 302 .

[0024] In this embodiment, the inspection cover 308 can be used to contain all structures located outside the side plate 302, so that the inspection cover 308 can effectively protect these structures.

[0025] Specifically, an electric push rod 309 is fixedly installed on the outer side of the side plate 302 , and a tooth plate 310 is fixedly connected to the movable end of the electric push rod 309 . The teeth of the tooth plate 310 are meshed with the top end of the follower gear 304 .

[0026] In this embodiment, the electric push rod 309 is started so that the movable end of the electric push rod 309 drives the tooth plate 310 to gradually descend, so that the tooth plate 310 gradually engages with the follower gear 304, thereby limiting the possible self-rotation of the follower gear 304, thereby further improving the stability of the contact between the contact plate 307 and the ground.

[0027] Specifically, a slide bar 311 is fixedly connected to the inner wall of the driving box 301 , and the slide bar 311 is slidably connected to the inner wall of the rack 306 .

[0028] In this embodiment, the rack 306 can slide along the surface of the slide bar 311, thereby improving the movement stability of the rack 306;

[0029] Furthermore, the maximum lifting distance of the rack 306 will not be greater than the path converted by the maximum number of rotations of the gear shaft 305 , so the rack 306 and the gear shaft 305 will not be separated.

[0030] When in use, the driving crawler structure 102 is started in advance, so that the driving crawler structure 102 can drive the dust suppression device 2 to move through the mobile base 101. When the device moves to the specified position, the driving crawler structure 102 is stopped, and the positioning structure 3 is started;

[0031] The external motor drives the driving gear 303 to rotate, and the rotation of the driving gear 303 drives the gear shaft 305 to rotate through the follower gear 304, and the rotation of the gear shaft 305 drives the rack 306 to mesh along the surface of the slide bar 311, so that the two racks 306 drive the contact plate 307 to move vertically, so that the contact plate 307 gradually contacts the ground, prompting the contact plate 307 to gradually lift the driving crawler structure 102 off the ground, so that the mobile base 101 switches from the movable mode to the positioning mode;

[0032] After the contact plate 307 contacts the ground, the driving gear 303 is stopped from rotating, and the electric push rod 309 is started, so that the movable end of the electric push rod 309 drives the tooth plate 310 to gradually descend, so that the tooth plate 310 gradually meshes with the driven gear 304, thereby limiting the possible self-rotation of the driven gear 304, thereby further improving the stability of the contact between the contact plate 307 and the ground;

[0033] Then, the extraction pump outside the water tank 201 is started, so that the extraction pump extracts water from the water tank 201 and injects it into the fog cannon 202, so that the fog cannon 202 sprays water mist to perform dust reduction treatment.

[0034] In summary, the dust reduction equipment for construction, by setting a positioning structure 3, uses the active gear 303 to drive the gear shaft 305 to drive the rack 306 to engage transmission through the follower gear 304, so that the rack 306 can drive the contact plate 307 along the surface of the slide bar 311 to adjust the height, so that the contact plate 307 gradually contacts the ground, and the contact plate 307 gradually lifts the driving crawler structure 102 off the ground, so that the mobile base 101 switches from the movable mode to the positioning mode, so that the dust reduction equipment can be fixed at the current position under the restriction of the contact plate 307, thereby avoiding the situation that the device in the comparative scheme is prone to self-sliding, making the use of the dust reduction equipment safer.
