Description

Technical Field

[0001] The utility model relates to the technical field of railway dust suppression vehicles, in particular to a spray device for a dust suppression vehicle. Background Art

[0002] Railway dust suppression vehicles are the key to preventing dust from being raised during the transportation of block, granular, and powdery materials such as sand, gravel, and coal. When a train passes by, dust suppressants are sprayed onto the materials in the open cargo box of the train through the spray pipes and nozzles of the dust suppression vehicle. The dust suppressants form a protective film on the surface of the materials, thereby preventing dust from being raised during railway transportation, avoiding dust pollution and material loss caused by dust, and is a boon for railway transportation.

[0003] The dust suppression truck's spray system primarily consists of a spray pipe and a spray head. To apply dust suppressant, the truck needs to park near the train tracks. The spray arm rotates, moving the spray pipe and nozzle above the tracks. As the train passes, the dust suppressant is sprayed downward. However, in practice, this is not a simple operation. To prevent waste of dust suppressant, the length of the spray pipe and the spray head's spray range are designed based on the width of the train's cargo box. The lateral distance between the two spray heads on either side of the spray pipe and the tracks is determined by the truck's distance from the tracks when it is parked. If the truck stops too close, materials in the cargo box closer to the spray arm won't be sprayed, causing dust to rise, while the spray heads farther from the spray arm will extend outside the cargo box, wasting dust suppressant. If the truck stops too far, the spray heads closer to the spray arm will remain outside the cargo box, wasting dust suppressant while materials farther from the spray arm won't be sprayed, causing dust to rise. Therefore, only when the parking position and distance of the dust suppression vehicle are just right can the optimal spraying of the dust suppressant be completed, which will neither cause dust nor waste of dust suppressant. However, the dust suppression vehicle is large in size, and it is undoubtedly difficult to ensure the accurate parking position. Therefore, there is a widespread phenomenon of incomplete dust suppression and waste of dust suppressant, which is insufficient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a dust suppression vehicle spraying device for solving the problem that the existing railway dust suppression vehicle needs to ensure the accurate parking position of the dust suppression vehicle to achieve the best spraying of dust suppressant, which makes the operation difficult.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A dust suppression vehicle spraying device includes a spraying arm, a spraying pipe installed on the spraying arm, a spraying head installed below the spraying pipe, and a conveying pipe connected to one end of the spraying pipe. The spraying arm is of a hollow structure. At the bottom of the inner wall of the spraying arm, a linear bearing seat is movably sleeved on the surface of the spraying pipe. At the top of the inner wall of the spraying arm, an electric push rod is fixedly connected. On the surface of the spraying pipe, a connecting frame located inside the spraying arm is fixedly connected. The telescopic end of the electric push rod is fixedly connected to the connecting frame.

[0007] Preferably, at one end of the spraying arm away from the spraying head, a "C"-shaped movable frame is movably connected. The upper half and the lower half of the movable frame are respectively located outside and inside the spraying arm. One end of the movable frame located inside the spraying arm is fixedly connected to the connecting frame. Connecting ears are fixedly connected to the top of the movable frame and the top of the spraying pipe away from one end of the spraying arm. A tensioned traction cable is tied between the two connecting ears.

[0008] Preferably, at the top of the inner wall of the movable frame, a support roller is fixedly connected. The support roller is in rolling connection with the upper surface of the spraying arm.

[0009] Preferably, a guide groove parallel to the spraying pipe is provided on the movable frame. A positioning guide roller is vertically installed on the upper surface of the spraying arm and is movably inserted into the guide groove.

[0010] Preferably, on the surface of the spraying pipe away from one end of the spraying arm, a mounting frame is fixedly connected. A camera and a laser pen are fixedly installed at the bottom of the mounting frame.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] By setting an electric push rod that can drive the spraying pipe and the spraying head to move along the spraying arm to adjust the position, under the guiding action of the movable frame and the linear bearing seat, the positions of the spraying pipe and the spraying head are adjusted to adapt to the position of the train freight car, so as to achieve the best spraying effect, which can not only spray comprehensively to prevent dust, but also avoid waste of dust suppressant, has low requirements for the parking position and distance of the dust suppression vehicle, brings great convenience to the railway dust suppression work, and solves the problem that the existing railway dust suppression vehicle needs to ensure the accurate parking position of the dust suppression vehicle to complete the best spraying of the dust suppressant, resulting in great operation difficulty.
