Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and more specifically, to a dust suppression device for underground construction passages. Background Technology

[0002] Underground construction engineering refers to engineering structures built underground or below water, including various industrial, transportation, civil and military underground projects. The history of underground construction engineering can be traced back to ancient times. In modern times, underground construction engineering has been widely developed in mining, underground transportation, municipal, industrial and hydraulic underground construction projects.

[0003] Chinese patent application CN202022802257.2 discloses an adjustable-height spray dust suppression device for underground construction. The device includes a base plate, which is L-shaped. A liquid storage tank is fixed to the upper end of the base plate, and an elastic hose is fixed to the upper end of the liquid storage tank. The lower end of the elastic hose passes through the base plate and communicates with it. A nozzle is fixed to the right end of the elastic hose, and the elastic hose communicates with the nozzle. From front to back, a drive box, a support box, and a pad are sequentially fixed to the upper right side of the base plate. The drive box and the support box have open ends near each other, and they communicate with each other. The upper end of a screw passes through the upper end of the support box and extends upwards. A drive mechanism is located inside the support box. This device allows for easy adjustment of the nozzle height without manual handling, is convenient and easy to operate, and provides stable fixation after adjustment, resulting in higher dust suppression efficiency in coal mines.

[0004] Although the above-mentioned patent utilizes a drive mechanism to easily adjust the height of the nozzle, eliminating the need for manual hand-holding, making it convenient and easy to operate, and providing a stable fix after adjustment, resulting in a higher dust reduction effect, it is worth noting that in the process of underground construction, the underground wind direction and wind pressure are mostly guided by fans. Therefore, when switching wind directions, the dust flow rate may be too fast, which may cause incomplete dust reduction, resulting in dust accumulation and a poor working environment.

[0005] In view of this, we propose a dust suppression device for underground construction passages. Summary of the Invention

[0034] Please see Figures 1-8 As shown, this embodiment provides a dust suppression device for underground construction passages, including a support frame 1. A crossbeam 11 is fixedly connected to one side of the support frame 1, and a fixing strip 111 is fixedly connected to one side of the crossbeam 11. A sliding chamber 2 is slidably connected to the crossbeam 1 on the side away from the support frame 1. A sliding plate 24 is slidably connected to the sliding chamber 2 on the side away from the support frame 1. A telescopic plate 241 is fixedly connected to the upper end of the sliding plate 24 on the side away from the sliding chamber 2. An adjustment component 3 is provided at the bottom of the telescopic plate 241, and a wind guide hood 4 is provided at the bottom of the adjustment component 3.

[0035] Wherein: the cross frame 11 is a horizontally distributed electric slide rail 23, and the sliding chamber 2 is installed on the cross frame 11.

[0036] like Figures 3-4 As shown, the sliding chamber 2 is internally hollow. A reciprocating screw 21 is rotatably connected inside the sliding chamber 2. A sliding block 211 is threaded onto the outer wall of the reciprocating screw 21. A touch sensor 212 is fixedly connected to one side of the sliding block 211. A turntable 22 is fixedly connected to the upper end of the reciprocating screw 21. The outer wall of the turntable 22 is in contact with the outer wall of the fixing strip 111. A vertical electric slide rail 23 is installed on the side of the sliding chamber 2 away from the crossbar 11. A sliding plate 24 is slidably connected to the electric slide rail 23. An electric telescopic rod 242 is fixedly connected to the lower end of the sliding plate 24 near the telescopic plate 241. The telescopic rod 242 penetrates the outer wall of the sliding chamber 2. The outer wall of the sliding chamber 2 has a strip-shaped hole for the sliding of the electric telescopic rod 242. The end of the electric telescopic rod 242 inside the sliding chamber 2 is fixedly connected to a contact plate 2421. The contact plate 2421 and the touch sensor 212 are in a relationship of being in the same vertical plane and fitting together. The end of the electric telescopic rod 242 away from the contact plate 2421 is fixedly connected to a fixing block 243. The fixing block 243 is fixedly connected to a bending plate 311 on the side away from the electric telescopic rod 242. The adjustment assembly 3 also includes a transmission chamber 31, which is fixedly connected to the bending plate 311.

[0037] like Figures 5-7As shown, a fixing frame 32 is fixedly connected to the side of the bent plate 311 away from the fixing block 243. The fixing frame 32 is composed of three parts: a square block, a right-angled bent block, and a cylinder. A first motor 321 is fixedly connected to one side of the right-angled bent block part of the fixing frame 32. A first rotating rod 322 is fixedly connected to the output end of the first motor 321. A threaded protrusion 323 is fixedly connected to the outer wall of the first rotating rod 322. A second motor 33 is fixedly connected to the top of the bent plate 311. A second rotating rod 331 is fixedly connected to the output end of the second motor 33. The second rotating rod 331 passes through... The square block portion of the fixing frame 32 has a first helical gear 332 fixedly connected to the end of the second rotating rod 331 away from the second motor 33. The inner side of the cylindrical portion of the fixing frame 32 is rotatably connected to a fixing post 34, which passes through the fixing frame 32. The upper end of the fixing post 34 is fixedly connected to a gear 341, which meshes with the threaded protrusion 323. The inner side of the fixing post 34 is rotatably connected to a third rotating rod 342, and the upper end of the third rotating rod 342 is fixedly connected to a second helical gear 3421, which meshes with the first helical gear 332.

[0038] like Figures 7-8 As shown, a triangular block 42 is fixedly connected to the lower end of the fixed column 34. The triangular block 42 is a right-angled triangular prism with an internal hollow structure. A helical gear 3422 is fixedly connected to the lower end of the third rotating rod 342. The helical gear 3422 is located inside the triangular block 42. A nozzle 43 is fixedly connected to the inclined surface of the triangular block 42. A fourth rotating rod 441 is rotatably connected to one side of the right-angled surface of the triangular block 42. The fourth rotating rod 441 passes through the triangular block 42. A helical gear 44 is fixedly connected to one end of the fourth rotating rod 441. The fan 442 is fixedly connected to the end of the fourth rotating rod 441 away from the fourth helical gear 44, meshing with the third helical gear 3422. The air guide shroud 4 is rotatably connected to the lower outer wall of the cylindrical part of the fixed frame 32. The fan 442 is located inside one end of the air guide shroud 4. A dust filter 41 is fixedly connected to the inner side of the end of the air guide shroud 4 away from the fan 442. An irregular notch is opened in the lower half of the outer wall of the air guide shroud 4. The irregular notch matches the orientation of the nozzle 43. The two sides of the triangular block 42 are fixedly connected to the inner wall of the air guide shroud 4 by a horizontal column.

[0039] Therefore, when dust suppression is required in underground construction passages, such as... Figures 3-7As shown, during the preparation stage, the device is installed on the crossbeam 11 on the support frame 1. Multiple devices can be installed in the passage supported by the support frame 1. When dust suppression is required in the passage, underground passages usually use fans to guide the wind direction and wind pressure. When the wind direction is determined, it is necessary to prevent dust from accumulating at the wind direction inlet. Therefore, a certain degree of dust suppression needs to be ensured during construction in the passage. As the construction location changes, the location to be dusted also needs to be adjusted.

[0040] like Figure 1 As shown, under the drive of the cross frame 11, the sliding chamber 2 drives the entire device to slide from one support frame 1 to another support frame 1. During the sliding process of the sliding chamber 2, the friction between the outer wall of the turntable 22 and the fixed strip 111 will drive the turntable 22 to rotate. At the same time, the turntable 22 drives the reciprocating screw 21 to rotate, and the reciprocating screw 21 will drive the sliding block 211 and the touch sensor 212 to move up and down together. When the touch sensor 212 slides to contact the contact plate 2421, the sliding chamber 2 stops sliding. At this time, the sliding chamber 2 stops inside the other support frame 1.

[0041] It should be noted that during the sliding process of the sliding chamber 2, the position of the contact plate 2421 can also be adjusted by moving the sliding plate 24 up and down through the electric slide rail 23, so as to adapt to the movement between supports at different distances.

[0042] When the wind direction changes, the airflow direction of the wind deflector 4 also needs to be adjusted, such as... Figures 6-7 As shown, driven by motor 33, rod 331 and helical gear 332 rotate together. During the rotation of helical gear 332, helical gear 3421, rod 342 and helical gear 3422 will also rotate together. Similarly, helical gear 3422 will drive helical gear 44, rod 441 and fan 442 to rotate together, and fan 442 will produce the effect of drawing air into the air guide shroud 4. This causes dust to flow from the fan 442 into the air guide shroud 4. At the same time, nozzle 43 sprays outward water mist to suppress dust. At this time, some dust flows out after being suppressed from the irregular gap at the bottom of the air guide shroud 4, while the rest of the dust is blocked by the dust filter 41. It should be noted that in the downwind state, the water mist sprayed by nozzle 43 flows in the same direction as the dust in the wind and mixes to suppress dust.

[0043] When different wind forces require different effects, the first rotating rod 322 and the threaded protrusion 323 rotate together under the drive of the first motor 321. Because the threaded protrusion 323 meshes with the gear 341, the rotation of the threaded protrusion 323 will drive the gear 341, the fixed column 34 and the triangular block 42 to rotate together, and at the same time drive the air guide shroud 4 to rotate. This allows the air guide shroud 4 to change direction, so that when the wind direction changes, the multiple nozzles 43 of this device on the support frame 1 form a water mist wall to block the dust in the wind when the wind force is too strong and the wind is against the wind, thus preventing the dust in the channel from being too large.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
