Abstract
The utility model relates to an auxiliary device for baseline measurement of ship, which is an auxiliary device that performs the measurement of the head and end lines of ship, parallel lines of the head and end lines, and the baseline of naval ships in the aligning experiments. The auxiliary device for baseline measurement of ship comprises a platform-shaped transparent shell that is small on the top and large on the bottom, the front and rear side faces of the transparent shell is marked with graduation lines, a magnet is arranged at the bottom of the transparent shell, a light source and a power supply are arranged in the transparent shell, a light source control switch is arranged above the transparent shell. The platform-shaped transparent shell is prism-shaped or cone-shaped. The auxiliary device has the advantages: 1. that the auxiliary device for baseline measurement is characterized in no being affected by time and weather, simple installation, small size, convenient use and portability, thereby facilitating to improve precision and efficiency of baseline measurement of ship; 2. of simple structure, easy making and low production cost.
Description
Technical field
The utility model relates to a kind of servicing unit that is used for the boats and ships base measurement, is to carry out the servicing unit in the alignment test naval vessels datum lines such as boats and ships fore and aft line, fore and aft line parallel lines measured at boats and ships.
Background technology
It is exactly the way that adopts reference frame translation, coordinate system conversion that boats and ships are aimed at, and the data of same attitude angle of each equipment and position on the ship are evened up.Be used to solve complete each equipment of ship the system zero bit integrity, it is based upon in the unified deck coordinate system.
The fore and aft line benchmark is a benchmark that often needs use during boats and ships are aimed on the deck, and its concrete implication is: ship center line face is meant the vertical plane of dividing hull from the warship bow to the warship stern along the naval vessel axis of symmetry equally, and it comprises the center line datum line of ship.The fore and aft line that is parallel to ship center line face, to be located at two groups or above fore and aft line sign composition on the deck, every group of fore and aft line sign comprised two identification plates 1, and three foreign dotting punches 2 (as shown in Figure 1) are arranged on each identification plate usually.
The measurement of boat deck fore and aft line is exactly the line of accurately measuring between two identification plates of one group of fore and aft line sign on the deck, its fore and aft line as ship center line face, in order to the benchmark of conduct to other data of locating tab assembly.Present specific practice is: set up the deck transit on an identification plate therein, the deck transit is by the line centering of three foreign dotting punches.On another identification plate, stick a paper label 3, three foreign dotting punch directions are drawn straight line in the paper label upper edge, take up an official post at straight line and look for 1: 4 (shown in Figure 1).Aim at this point measurement ship fore and aft line with the deck transit then.
Because general alignment work all between the lights or carry out night, therefore the measurement of fore and aft line at present generally needs two people, one man operation deck transit, the reference point of a people paper label one end throws light on the indication paper label by torch on.Because distance has more than 100 meter or longer between two identification plates, identification plate is in deck level again, and therefore difficulty when so just having caused remote level to sight on the paper label reference point, also needs personnel by reference point on the nib indication paper label usually.As can be seen, classic method is in measuring process, and testing crew needs to provide indication and illumination to reference point on the paper label for a long time, and the error of rocking meeting increase base measurement of staff.So not only use inconvenience, and the efficient and the precision of influence measurement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of servicing unit that is used for the boats and ships base measurement at the deficiency of above-mentioned prior art existence, it can provide a stable witness mark clearly for the measurement of boats and ships baseline, not only easy to use, and efficient and the precision measured are higher.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include up-small and down-big platform shape transparent shell 6, the forward and backward side of transparent shell is marked with scale mark 7, the bottom of transparent shell is installed on magnet 13, be provided with light source 10 and power supply 11 in the transparent shell, on transparent shell, be provided with light control switch 12.
Press such scheme, described shape transparent shell 6 is terrace with edge shape or truncated cone-shaped.
Press such scheme, the left and right side of described transparent shell is marked with and the perpendicular scale mark of front and back scale mark.
The beneficial effects of the utility model are: 1, the servicing unit as base measurement has the influence that work is not subjected to time, weather, installs simply, and volume is little, the use convenient carrying, helps to improve the precision and the efficient of boats and ships base measurement; 2, simple in structure, be easy to make, and cost of manufacture is low.

Embodiment
Further describe embodiment of the present utility model below in conjunction with accompanying drawing.
Include up-small and down-big positive truncated rectangular pyramids shape transparent shell 6, last bottom surface is a square, last bottom and high ratio 1: 2: 1; Transparent shell is made by organic glass, and the center indicates scale mark 7 on the front and back sides 8 of transparent shell, also indicates on the sidewall of the left and right sides of transparent shell and the perpendicular scale mark of front and back scale mark.Laterally inclined, the scale mark of lateral surface around being convenient to sight from afar.Be installed on ring-shaped magnet 13 in the bottom 5 of transparent shell, be provided with light source 10 and power supply 11 in the transparent shell, light source can be the light emitting diode that has color, helps device and illuminating lamp are on every side distinguished.Be provided with light control switch 12 on transparent shell, gauge tap is a hand push button formula switch, the conducting and the disconnection of control power supply and light source.
The utility model use is as follows:
Aiming at before operation begins, on the identification plate 1 of ship deck one end, connecting foreign dotting punch 2 on it, then center scale on the opposite face of transparent shell 7 and drawn aligned with the pencil drawing straight line; Set up the deck transit at another monumented point place.As by day or under the enough condition of light, place the measuring operation that the back just can be carried out baseline by the deck transit.As operating at night, place device after, press shift knob, allow light source igniting, just the personnel of setting up can withdraw, do not need to wait at this for a long time.To be measured finishing by personnel's powered-down, fetched servicing unit again.
