[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] This invention proposes a dust suppression device for drilling in the sidewalls, as described below. Figs. 1 to 4 Please provide a detailed explanation.

[0026] A dust suppression device for drilling construction in the side wall includes a dust suppression box 1, with a spray opening 2 on the bottom surface of the dust suppression box 1, a dust suppression spray assembly 3 inside the dust suppression box 1, a water supply assembly 4 connected to the spray assembly 3, and multiple sets of telescopic brackets 5 hinged to the edge of the dust suppression box 1 on one side of the spray opening 2.

[0027] This invention features a dust suppression box 1 equipped with a spray assembly 3. When drilling operations are required, the dust suppression box 1 is supported above the drilling location using multiple sets of retractable supports 5. The spray assembly 3 is then activated, spraying water mist to suppress dust during the drilling process. Furthermore, the dust suppression box 1 and the multiple sets of retractable supports 5 make the device easy for workers to carry. The water supply assembly 4 can be directly connected to the water supply pipeline inside the tunnel, ensuring stable dust suppression for workers drilling at different locations.

[0028] In one embodiment, the dust collection box 1 is arranged in a rectangular parallelepiped structure, and the dimensions of the dust collection box 1 are set to be 0.5m in length, 0.5m in width, and 0.5m in height.

[0029] In some embodiments, the spray assembly 3 includes multiple sets of spherical nozzles 31 disposed on the inner wall of the dust suppression box 1. The multiple sets of spherical nozzles 31 are connected to each other through an internal pipe 32, and the internal pipe 32 is connected to the water supply assembly 4. The arrangement of the spherical nozzles 31 can achieve multi-angle spraying, thereby spraying the drilling operation space covered below the dust suppression box 1 from multiple angles and directions to suppress dust, so that the water mist can cover the space where flying dust is generated to the greatest extent and maximize the dust suppression effect.

[0030] In some embodiments, the water supply assembly 4 includes a water supply pipe 41 that is connected to the pipe 32 inside the box, and a water supply hole 42 is provided on the side wall of the dust settling box 1 for the water supply pipe 41 to pass through and be inserted.

[0031] A control valve 43 is installed on the water supply pipe 41.

[0032] Water supply pipe 41 can be directly connected to the water supply pipeline in the tunnel, thereby obtaining water from the water supply pipeline in the tunnel, and controlling the flow rate of water through control valve 43. In one embodiment, control valve 43 is set as a ball valve.

[0033] In some embodiments, the water supply pipe 41 is configured as a high-pressure hose. The high-pressure hose ensures that the water supply pipe 41 will not crack due to excessive pressure when supplied with high-pressure water, and also facilitates the storage and handling of the water supply pipe 41 by personnel. In one embodiment, the high-pressure hose has an inner diameter of 19mm.

[0034] In some embodiments, at least one set of symmetrical spherical nozzles 31 are provided on the inner sidewalls of the dust collection box 1, and a spherical nozzle 31 is provided on the inner top wall of the dust collection box 1 facing the spray opening 2. That is, at least one set of horizontally facing spherical nozzles 31 are provided inside the dust collection box 1, and a spherical nozzle 31 is provided facing the lower drill hole position, thereby improving the spatial coverage of water mist and ensuring the dust suppression effect. In one embodiment, a total of 3 spherical nozzles 31 are provided, of which two spherical nozzles 31 are horizontally facing each other, and the third spherical nozzle 31 is provided on the inner top wall facing the spray opening 2.

[0035] In some embodiments, the telescopic bracket 5 includes a hinge rod 51 hinged to the dust collection box 1. A support rod 52 is sleeved on the end of the hinge rod 51 away from the dust collection box 1. A receiving cavity 53 is provided inside the support rod 52 for the hinge rod 51 to be inserted into. A locking mechanism for locking the position of the support rod 52 is provided between the hinge rod 51 and the support rod 52. The sleeved arrangement of the support rod 52 and the hinge rod 51 allows for length adjustment of the telescopic bracket 5. Depending on the conditions at the construction site, the workers adjust the length of the hinge rod 51 inserted into the receiving cavity 53. After adjusting to the required length, the workers lock the relative position between the support rod 52 and the hinge rod 51 by adjusting the locking mechanism.

[0036] In some embodiments, the locking mechanism includes a locking hole 54 disposed on the side wall of the support rod 52, and a fixing bolt 55 is internally threaded into the locking hole 54. The locking hole 54 and the fixing bolt 55 facilitate the adjustment of the position of the fixing bolt 55 by the operator. When it is necessary to adjust the length of the hinge rod 51 inserted into the receiving cavity 53, the operator controls the fixing bolt 55 to move away from the receiving cavity 53. At this time, there is a gap between the fixing bolt 55 and the outer wall of the hinge rod 51, and the operator can easily control the support rod 52 to move, thereby adjusting the length of the hinge rod 51 inserted into the receiving cavity 53. After the length is adjusted, the operator controls the fixing bolt 55 to move towards the receiving cavity 53, so that the fixing bolt 55 presses against the surface of the hinge rod 51, thereby completing the fixing of the hinge rod 51.

[0037] In some embodiments, a control handle 56 is provided at the end of the fixing bolt 55 away from the support rod 52. The control handle 56 facilitates the operation of the fixing bolt 55 by the operator.

[0038] In some embodiments, the dust collection box 1 is provided with a hinge ear 11 that is hinged to the telescopic bracket 5. The hinge ear 11 facilitates the hinged connection of the telescopic bracket 5 by the operator.

[0039] In some embodiments, the retractable supports 5 are symmetrically arranged on both sides of the dust collection box 1, and at least two sets of retractable supports 5 are provided on each side. The number of hinge ears 11 is the same as the number of retractable supports 5. The symmetrical and single retractable supports 5 can play a role in stable support. In one embodiment, two sets of retractable supports 5 are provided on each side, that is, a total of 4 sets of retractable supports 5 on both sides, thereby providing stable support for the dust collection box 1.
