Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure spraying, in particular to a high-pressure spraying device for coal mine construction and excavation. Background Art

[0002] In order to ensure safe production during the coal mining process, it is generally necessary to install a high-pressure spray device in the mine. The nozzle sprays to form an atomized water curtain, and infrared sensors are installed in the tunnels on both sides of the spray point to form two infrared detection lines. When there are no vehicles or people passing by, the spraying is continuous or staged. When a vehicle or person is about to pass by, the spraying is stopped. After a period of time (which can be set according to actual needs), the spraying operation is started again.

[0003] Although the current high-pressure spray device has the ability to reduce dust and improve construction safety, the positions of most spray heads are fixed and cannot be adjusted. As a result, when the number of spray heads is set to a small number, the spray range will be affected. When a large number of spray heads is set, some spray heads will be idle due to insufficient water pressure. Based on this, we propose an improved high-pressure spray device for coal mine construction excavation. Utility Model Content

[0023] In this embodiment, a plurality of rivets 2 are threadedly sleeved on the embedded plate 1, so as to facilitate the stable installation of the device on the ground. Vertical plates 3 are fixedly connected to both sides of the upper end surface of the embedded plate 1, and the two vertical plates 3 are fixedly connected to the lower end of the support plate 4.

[0024] In this embodiment, the main pipe 6 is arranged between the mounting plate 5 and the vertical plate 3. The upper ends of the two mounting plates 5 and the two main pipes 6 are fixedly connected to the lower end surface of the support plate 4. The main pipe 6 and the hose 19 are protected by the mounting plate 5 and the vertical plate 3.

[0025] In this embodiment, multiple positioning pins 15 are fixedly connected to end caps at one end away from the connecting plate 14, and springs 16 are fixedly connected between the multiple end caps and the connecting plate 14. The multiple springs 16 are respectively movably sleeved on the outer walls of the multiple positioning pins 15. The springs 16 are mainly used to prevent the positioning pins 15 from detaching from the connecting plate 14.

[0026] In this embodiment, multiple hoses 19 are fixedly connected between the multiple spray heads 17 and the main pipe 6. The multiple hoses 19 are evenly distributed on the outer wall of the main pipe 6. The liquid in the main pipe 6 is pumped into the spray head 17 through the hoses 19 and sprayed out.
