Special trailer for spraying paint on helicopter body

Abstract

The utility model discloses a special trailer for spraying paint on a helicopter body, which relates to the field of trailers and comprises a chassis, universal wheels are mounted at four corners of the bottom end of the chassis, bogies are arranged at the front end and the rear end of the chassis, steering wheels are mounted at the bottom ends of the bogies, and connectors are movably mounted at the front ends of the bogies in a penetrating manner. And a bottom frame is fixedly mounted at the top end of the chassis. By arranging the bogie, the rotating shaft, the sliding rail and the material box, the problems that a traditional special trailer for spraying paint on a helicopter body is inconvenient to turn around in a limited space due to the fact that a single connector is adopted for connecting a traction device, and steering wheels and universal wheels are always located in the same plane and cannot be adjusted when passing through a slope surface and are not beneficial to adapting to the angle of the slope surface are solved. And meanwhile, the position of a spray gun can only be adjusted through a material conveying hose, the adjusting range is too small, paint spraying on different positions of a helicopter body is not facilitated, and only the position of the whole special paint spraying trailer can be directly adjusted.

Description

Technical Field

[0002] A special trailer for painting is a special trailer used for painting operations. Compared with traditional trailers, in addition to the trailer itself, it also includes equipment for painting operations and a height-adjusting structure. During the painting operation, the height of the equipment for painting operations is adjusted by the height-adjusting structure. The present scheme specifically relates to a special trailer for helicopter body painting. The existing special trailer for helicopter body painting uses a single connector to connect the traction device, which is not convenient for the trailer to turn around in a limited space. At the same time, when passing through a slope, the steering wheel and the universal wheel are always in the same plane and cannot be adjusted, which is not conducive to adapting to the angle of the slope. At the same time, the position of the spray gun can only be adjusted through the feed hose, and the adjustment range is too small, which is not conducive to painting different positions of the helicopter body. The position of the entire special trailer for painting can only be adjusted directly, which is not convenient enough. Utility Model Content

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 3As shown, a special trailer for painting helicopter bodies includes a chassis 1, universal wheels 2 are installed at the four corners of the bottom end of the chassis 1, bogies 3 are provided at the front and rear ends of the chassis 1, steering wheels 5 are installed at the bottom end of the bogies 3, a connector 4 is movably installed through the front end of the bogies 3, a base frame 6 is fixedly installed at the top of the chassis 1, a lifting frame 7 is installed through the top surface of the base frame 6, a top frame 8 is installed at the top of the lifting frame 7, a pan-tilt 9 is fixedly installed at the top of the top frame 8, a guardrail 10 is fixedly installed at the top of the pan-tilt 9 near the edge, two slide rails 11 are installed at the top of the pan-tilt 9 and on the inner side of the guardrail 10, a material box 12 is installed between the two slide rails 11, a material delivery hose is installed at the top of the material box 12, and a spray gun 13 is installed at the top of the material delivery hose.

[0019] Docking grooves 14 are provided through the upper and lower ends of the chassis 1 and near the four corners. A rotating shaft 15 is fixedly installed inside the docking groove 14 . The docking groove 14 and the rotating shaft 15 are provided to facilitate docking with the chassis 1 .

[0020] The top and bottom ends of the lifting frame 7 are slidably connected to the top frame 8 and the bottom frame 6 respectively. By setting the lifting frame 7, it is convenient to adjust the height of the pan / tilt platform 9, so as to facilitate painting at different heights of the helicopter body.

[0021] The material box 12 is slidably connected to the slide rail 11 , and the material box 12 is pushed to slide along the direction of the slide rail 11 , so as to facilitate the adjustment of the position of the material box 12 .

[0022] A paint pump is installed inside the material box 12, and the outlet of the paint pump is connected to a feed hose. During the painting process, the paint pump inside the material box 12 starts to absorb the paint and transports it to the spray gun 13 through the feed hose for painting.

[0023] The bogie 3 is movably connected to the chassis 1 via the rotating shaft 15, so that the bogie 3 can be folded easily. Meanwhile, when the helicopter body painting trailer moves to an uphill road surface, the bogie 3 can be rotated to adapt to the angle of the slope.

[0024] It should be noted that the utility model is a special trailer for painting helicopter bodies. When in use, firstly, a traction device is connected to the outside through the connector 4, and the traction device cooperates with the universal wheel 2 to tow the special trailer for painting helicopter bodies to the painting site. During the movement of the special trailer for painting helicopter bodies, the bogie 3 and the steering wheel 5 are coordinated to adjust the forward direction. If a slope is encountered, the bogie 3 rotates around the rotating shaft 15 to adapt to the angle of the slope.

[0025] After the helicopter body painting trailer moves to the bottom of the helicopter body, the lifting frame 7 is lowered to drive the pan-tilt platform 9 to descend. After the worker climbs onto the pan-tilt platform 9, the material box 12 is pushed to slide along the direction of the slide rail 11, and the opening of the guardrail 10 is blocked by the material box 12 to prevent the worker from falling from the opening during the construction process. At the same time, during the process of painting the helicopter body, the material box 12 is pushed along the direction of the slide rail 11, and the position of the spray gun 13 is adjusted in a small range to facilitate the painting operation;

[0026] During the movement of the helicopter body painting trailer, two connectors 4 are used to connect two traction devices respectively, so that the helicopter body painting trailer can turn around in a limited space.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
