Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler trucks, in particular to an underground tunnel sprinkler truck. Background Art

[0002] Sprinkler trucks are vehicles that can perform functions such as flushing, watering, and dust reduction. Due to the influence of natural conditions, underground tunnels are contaminated with large amounts of coal dust and powder. Sprinkler trucks are needed to flush and reduce dust to ensure that the underground tunnels are clean and tidy, which is conducive to the normalization of underground tunnel safety production standards.

[0003] Due to the accumulation of dust inside the underground tunnels over time, flushing is very difficult. The distance between the spray head of the water sweeper and the flushing position of the underground tunnel cannot be flexibly adjusted, resulting in the spray head being unable to adapt to the internal space of the underground tunnel and the distance between it and its inner wall. The flushing force is low, which is not conducive to quickly flushing away the accumulated dust. Moreover, when using a sprinkler truck to reduce dust in the underground tunnel, the angle of the spray head cannot be flexibly adjusted, so that it cannot effectively face the direction of the dust, affecting its dust reduction effect. Therefore, we proposed an underground tunnel sprinkler to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-6 The utility model provides the following technical solution: an underground tunnel sprinkler, comprising a frame 1, a water tank 2 is mounted above the frame 1, a support rod 3 is mounted behind the water tank 2, a rear end of the support rod 3 is connected to a support ring 4, and a moving rod 6 is connected to the side wall of the support ring 4 via a connecting spring 5;

[0027] Furthermore, the movable rods 6 are distributed at equal angles with respect to the center point of the support ring 4. The movable rods 6 pass through the edge of the support ring 4 and are slidably connected to the support ring 4. The position of the movable rods 6 can be flexibly adjusted, and the movable rods 6 distributed at equal angles can facilitate the assembly of the nozzle 9 in different orientations.

[0028] One end of the moving rod 6 is rotatably connected to a rotating shaft 7, a vortex spring 8 is connected to the connecting end of the rotating shaft 7 and the moving rod 6, the other end of the moving rod 6 is rotatably connected to a roller 21, and a nozzle 9 is installed on the outer side of the rotating shaft 7;

[0029] Furthermore, the nozzle 9 and the movable rod 6 form a rotating structure, and the nozzles 9 are connected to each other through a hose 12, so that the angle of the nozzle 9 can be adjusted to adjust the spraying direction of the water;

[0030] A water pump 10 is installed at the upper rear of the water tank 2. The water inlet of the water pump 10 is connected to the water tank 2. The water outlet of the water pump 10 is connected to a connecting pipe 11. The rear end of the connecting pipe 11 is connected to a hose 12. The hose 12 is connected to the nozzle 9. A mounting bracket 13 is installed at the upper rear of the frame 1. A hydraulic rod a14 is installed on the rear side of the mounting bracket 13. The output end of the hydraulic rod a14 is connected to an adjustment block 15.

[0031] Furthermore, the adjustment block 15 is a truncated cone-shaped structure, and the adjustment block 15 and the roller 21 are in contact with each other. When the adjustment block 15 moves to push the moving rod 6 to move, the roller 21 is used to reduce the moving friction between the two.

[0032] The mounting frame 13 is provided with a moving component for adjusting the angle of the nozzle 9;

[0033] Furthermore, the moving assembly includes a hydraulic rod b16 mounted on the rear side of the mounting frame 13. The output end of the hydraulic rod b16 is connected to a connecting ring 17. A fixing column 18 is mounted on the connecting ring 17. An adjusting rod 19 is slidably connected to the interior of the fixing column 18. A protruding rod 20 is mounted on the end of the adjusting rod 19.

[0034] Furthermore, a section of the convex rod 20 away from the adjusting rod 19 is a "7"-shaped structure, the end of the convex rod 20 is in contact with the nozzle 9, and the end of the convex rod 20 close to the adjusting rod 19 passes through the outer wall of the movable rod 6 and is slidably connected to the movable rod 6, which can ensure the stable movement of the convex rod 20 and the relative position between the convex rod 20 and the nozzle 9 remains unchanged, so that the nozzle 9 is driven to rotate by driving the convex rod 20 to move;

[0035] Specifically, when the sprinkler truck moves on the track of the underground tunnel, the hydraulic rod a14 can be opened to push the adjusting block 15 connected to the output end to move backward. At this time, the roller 21 rolls on the adjusting block 15, so that the adjusting block 15 pushes the moving rod 6 to move away from the adjusting block 15. The moving rod 6 stretches and stores force on the connecting spring 5, and the moving rod 6 controls the nozzle 9 installed at the end to move. At the same time, the moving rod 6 drives the convex rod 20 passing through the upper end to move, and the adjusting rod 19 installed at the end of the convex rod 20 slides in the fixed column 18 to realize the position adjustment of the nozzle 9. Adjust the position, expand and extend the nozzle 9, shorten the distance between the nozzle 9 and the inner wall of the underground tunnel, connect the water pump 10 to the power supply, and transport the water in the water tank 2 to the connecting pipe 11. The connecting pipe 11 transports the water to the nozzle 9 for spraying. The short-distance spraying can increase the impact force of the nozzle 9 spraying to the underground tunnel, and quickly flush away the deposited dust in the underground tunnel. After the flushing is completed, the adjustment block 15 can be controlled to move forward and reset, and the push on the moving rod 6 can be released. The connecting spring 5 can control the moving rod 6 to reset and move, thereby controlling the nozzle 9 to reset;

[0036] If it is necessary to suppress the floating dust in the underground tunnel, when the sprinkler truck moves toward the direction of the dust, the hydraulic rod b16 can be opened to push the connecting ring 17 connected to the output end backward, thereby controlling the fixed column 18 to move backward. At this time, the adjusting rod 19 inside the fixed column 18 moves backward synchronously, driving the convex rod 20 installed on the upper end of the adjusting rod 19 to move backward. At this time, the convex rod 20 slides on the upper end of the moving rod 6, and the convex rod 20 pushes the nozzle 9, so that the nozzle 9 rotates on the moving rod 6 through the rotating shaft 7. The vortex spring 8 connected to the end of the rotating shaft 7 rotates synchronously to accumulate force, adjust the angle of the nozzle 9, and make the nozzle 9 spray water in the direction of the dust to quickly suppress it.
