Abstract
Description
Technical Field
[0001] The utility model belongs to surveying and mapping technology, in particular to a bottom line surveying and mapping device for external protrusions of a passenger car. Background Art
[0002] However, currently, in the detection of external protrusions of passenger cars, a cone with a half angle of 30° is usually used to determine the bottom line of the vehicle. By continuously contacting the cone along the lowest position that can be contacted on the outer surface of a fully loaded vehicle, the geometric trajectory of these contact points is the bottom line. The outer surface parts of the vehicle above the bottom line and within the area 2m below the ground need to be tested for protrusion regulations.
[0003] The cone is not convenient to move during use, and the contact point between the cone and the surface to be measured is not easy to mark. Most of the time, multiple points are marked and then connected to form a trajectory line, which cannot form a continuous trajectory line, which will increase the error of drawing the bottom line and affect the detection result.

[0020] Figure 2 It is a schematic diagram of the use of the present invention. DETAILED DESCRIPTION
[0021] A device for measuring and mapping the bottom line of external protrusions of a passenger car comprises a cone measuring body 1, a rotating shaft 2, an ink storage cartridge 4, a base 8 and an ink supply arm 3. One end of the rotating shaft 2 passes through the central axis of the cone measuring body 1 and is fixed to the base 8, and the other end passes through the cone measuring body 1. The cone measuring body 1 rotates around the rotating shaft 2. One end of the ink supply arm 3 is fixed to the base 8, and the other end is fixed to the other end of the rotating shaft 2. A brush 10 is provided on the ink supply arm 3, and the brush 10 contacts the cone measuring body 1. The ink storage cartridge 4 is arranged at the other end of the rotating shaft 2. The ink storage cartridge 4 is connected to the ink supply arm 3 through an ink supply tube to supply ink to the ink supply arm 3. An ink leakage hole is provided at the connection between the ink supply arm 3 and the brush 10, and ink flows out of the ink leakage hole and adheres to the brush bristles.
[0022] In a further embodiment, the surface of the cone measuring body 1 is a rough surface. For example, a plurality of scratch grooves are formed by a honing process. The scratch grooves have an irregular shape and may be a plurality of annular grooves or a plurality of staggered grooves.
[0023] In a further embodiment, the half angle of the cone measuring body 1 is 30° and the height is 1.25 m.
[0024] In a further embodiment, a circle of waste liquid grooves 7 are provided on the bottom surface of the cone measuring body 1 along the circumferential direction for collecting waste ink.
[0025] In a further embodiment, the center of the cone measuring body 1 is connected to the rotating shaft 2 via a bearing to achieve rotation around the rotating shaft 2 .

[0027] In a further embodiment, a control handle is provided at the other end of the rotating shaft 2 to facilitate pushing the surveying and mapping tool forward.
[0028] In a further embodiment, the ink storage box 4 is provided with an ink filling port 6 .
[0029] When the present invention is used for surveying, the cone measuring body 1 is kept in continuous contact with the outer surface of the vehicle body. The device of the present invention is moved around the outer surface of the vehicle body, and the cone measuring body 1 rotates around the rotation axis 2 during the movement, and the ink on the brush 10 adheres to the surface of the cone measuring body 1, and adheres to the outer surface of the vehicle body through the contact between the cone measuring body 1 and the vehicle body.
[0030] The line connecting the lowest position that the vehicle can contact with the cone measuring body 1 is determined as the bottom line. Different from the existing method, the device of the present invention can form a continuous track line, and the ink can directly form the bottom line mark on the vehicle body.
