Abstract
The invention discloses an assistant tool for measuring the coordinate position of a shield part of a ship. The assistant tool comprises a steel ruler part with scales and a light reflecting part. One end of the steel ruler part is sharpened to form a protruded tip. The other end is provided with a protruded cylinder. The cylinder is inserted into a groove arranged on one end of the light reflecting part. The light reflecting part is a steel ruler provided with a first light reflecting sheet and a second light reflecting sheet. The groove and the protruded cylinder are used to connect the steel ruler part and the light reflecting part so as to ensure that the center of the first light reflecting sheet, the center of the second light reflecting sheet, and the tip of the steel ruler part are in the same line. The light reflecting part can rotate on the steel ruler part so as to make the first light reflecting sheet and the second light reflecting sheet stay on the positions where the first light reflecting sheet and the second light reflecting sheet can be measured. The provided assistant tool utilizes the coordinate of measurable area of a total station to calculate the coordinates of a shield area to be measured, the coordinates of the shielded area can be obtained without building a new whole station; and solved is the problem that the whole station cannot measure a shielded area.
Description
Technical field
The present invention relates to a kind of hull and measure aid, particularly a kind of hull is blocked place's coordinate position measures aid, and uses this aid to carry out hull by the method blocking place's position measurement.
Background technology
Present stage, the simulation at hull construction is carried and is measured in operation process, it is often necessary to repeatedly set up total powerstation by relevant range perfect measurement.Trace it to its cause, be, total powerstation is high-accuracy measuring instrument, device operation process is affected bigger by objective environment, and generally there are the equipment such as substantial amounts of scaffold, blower fan production scene, some is often made to need the position measured to be blocked, total powerstation cannot directly be measured, so again setting up total powerstation to avoid blocking.
Repeatedly setting up total powerstation and increase labor intensity to a certain extent, not only the speed of operation is measured in impact, also affects the accuracy of measurement data, and then the accuracy of operation is carried in impact simulation, thus restricts precision and the quality of shipbuilding.In order to avoid repeatedly setting up total powerstation, measurement need a kind of can help measure the measurement aid by occlusion area.
Summary of the invention
Object of the present invention is to provide and a kind of may be used for measuring hull by the aid of the coordinate position of occlusion area, with solve band measure local be blocked time, total powerstation cannot detect, the problem needing additionally to set up.
Another object of the present invention, is that providing a kind of uses above-mentioned aid to hull by blocking the method that position measures.
Of the present invention a kind of for measuring hull by the aid blocking place's coordinate position, including steel ruler portion with a scale and light-reflecting portion, one end, described steel ruler portion sharpening forms tip outwardly, the other end arranges cylinder outwardly, and this cylinder inserts in the groove for insertion that light-reflecting portion one end is arranged;Light-reflecting portion is a steel ruler being provided with the first reflecting piece and the second reflecting piece, and by its upper groove arranged and the connection of the cylinder outwardly steel ruler portion that adapts therewith, with the tip at the first reflecting piece center and the second reflecting piece center and steel ruler portion that ensure light-reflecting portion on the same line;Light-reflecting portion can rotate to ensure that the first reflecting piece, the second reflecting piece are in position that can be measured in steel ruler portion.
The method that hull is measured by the above-mentioned aid of use of the present invention by the place of blocking, comprises the steps:
Fixing total powerstation is installed, chooses datum mark;
This aid is adjacent to region to be measured makes the tip in its steel ruler portion be directed at tested point;
Regulation steel ruler portion length, rotate light-reflecting portion, make the first reflecting piece, the second reflecting piece be in can be measured position;
Measure the tip in steel ruler portion to the first reflecting piece or the distance of the second reflecting piece;
Total powerstation is used directly to measure the first reflecting piece and the position of the second reflecting piece;
Set up coordinate system, in setting up coordinate system, draw the first reflecting piece and the coordinate points of the second reflecting piece, connect Two coordinate point and to the most advanced and sophisticated extension in steel ruler portion;
Tip according to steel ruler portion, to the first reflecting piece or the distance of the second reflecting piece, determines the most advanced and sophisticated position in steel ruler portion, and measures its coordinate, complete the measurement to tested point coordinate.
A kind of hull of the present invention measures aid, it is blocked in region to be measured, when total powerstation cannot directly be measured, this aid is adjacent to region to be measured makes the tip in its steel ruler portion be directed at tested point, rotate light-reflecting portion make the first reflecting piece, the second reflecting piece be in can be measured position, total powerstation can directly measure the first reflecting piece and the position of the second reflecting piece.Due to the first reflecting piece of light-reflecting portion and the second reflecting piece center and steel ruler portion tip on the same line, so in the same coordinate system, the coordinate at tested point coordinate and the first reflecting piece and the second reflecting piece center meets same linear equation;Again because total powerstation can measure the first reflecting piece and the position of the second reflecting piece, steel ruler portion and light-reflecting portion per se with scale may determine that tested point and the first reflecting piece center and the distance at the second reflecting piece center, so the linear equation by the two can be determined by the coordinate at the first reflecting piece center and the second reflecting piece center, then determined the coordinate of tested point by the distance of tested point and the first reflecting piece center and the second reflecting piece center.A kind of hull of the present invention measures aid, utilize total powerstation the coordinate of measured zone can calculate the coordinate in the region to be measured being blocked, the coordinate in the region to be measured being blocked can be obtained without again setting up total powerstation, both avoided and again set up the repeated work brought, also add and again set up the measurement error brought on a small quantity, decrease objective factor and simulation is carried the impact measuring operation, on the premise of ensureing measurement data accuracy, improve measurement working performance.
