Background
The modular construction is a method widely adopted by modern land factories, offshore oil production platforms and shipbuilding, and is beneficial to integrating global dominant resources, reducing engineering cost and shortening construction period. The modularization construction project often meets the accurate positioning work of large-scale equipment installation, and because the accurate position of equipment manufacturer equipment base bolt trompil can not be learnt in the project design initial stage, the condition that the bolt can not freely penetrate after the trompil according to the drawing theoretical dimension appears as the direction to not having real data when positioning the trompil to equipment, brings inconvenience for the construction.
SUMMERY OF THE UTILITY MODEL
To the technical problem who mentions in the background art, the utility model provides a can pinpoint the device of the true position of equipment body bolt hole fast, provide accurate guidance for the site operation.
The utility model adopts the following technical proposal: a bolt accurate measurement positioning device comprises a total station prism, a connecting bolt and a mapping cone, wherein a level gauge is arranged at the top of the total station prism, and the upper end and the lower end of the connecting bolt are respectively in threaded connection with a first threaded hole in the bottom of the total station prism and a second threaded hole in the upper surface of the mapping cone; survey and drawing circular cone is the smooth solid right circular cone of metal in surface, and its upper surface is the large diameter face that the diameter is 70mm, the second screw hole is located upper surface positive central point, survey and drawing circular cone's axial section circular cone half angle scope is between 25-50.
Compared with the prior art, the utility model has the advantages of: the utility model discloses a bolt precision measurement positioner utilizes connecting bolt to link together survey and drawing circular cone and total powerstation prism, put into the bolt hole of equipment under test with the survey and drawing circular cone, the survey and drawing circular cone can be automatic in the diameter is less than 70mm within range and coincides with bolt hole axis, and simultaneously, recycle the spirit level from the area on the total powerstation prism with this measurement positioner leveling, acquire with the position of total powerstation prism center coincidence, thereby measure the accurate coordinate that obtains bolt hole vertical position through the total powerstation prism, acquire the true position of bolt hole.

fig. 2 is a cross-sectional view of a mapping cone of the bolt precision measurement positioning device of the present invention;
wherein, the system comprises a total station prism 1, a connecting bolt 2, a surveying and mapping cone 3 and a level meter 4.
Detailed Description
Hereinafter, in order to facilitate the technical solution of the present invention to be understood by those skilled in the art, further description will be made with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the invention. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Please refer to fig. 1, for the utility model discloses a bolt precision measurement positioner's overall structure sketch map, including total powerstation prism 1, connecting bolt 2 and survey and drawing circular cone 3, what this embodiment adopted is come the total powerstation prism of card 1202+ model and measures, and total powerstation prism 1 top is equipped with spirit level 4, can also adopt other models certainly, satisfy the measurement requirement can. The upper end and the lower end of the connecting bolt 2 are in threaded connection with a first threaded hole in the bottom of the total station prism 1 and a second threaded hole in the upper surface of the surveying and mapping cone 3 respectively; please refer to fig. 2, which is a cross-sectional view of the surveying and mapping cone of the bolt precise measurement positioning device of the present invention, the surveying and mapping cone 3 is a metal solid right circular cone with a smooth outer surface, the upper surface thereof is a large diameter surface with a diameter of 70mm, the second threaded hole is located at the center of the upper surface, and the axial section cone half angle α of the surveying and mapping cone 3 is in a range of 25-50 °. The measurement principle of the device is as follows: the device is placed in a bolt hole of the equipment to be tested, the mapping cone 3 can automatically coincide with the central axis of the bolt hole to be tested within the range that the diameter is smaller than 70mm, the measuring device is leveled by the level instrument 4 arranged on the total station prism 1, the position coinciding with the center of the total station prism 1 is obtained, the coordinate of the vertical position of the bolt hole is obtained through the measurement of the total station, and therefore the real position of the bolt hole is obtained.
In the manufacturing process of the device, the second threaded hole in the middle of the mapping cone 3 is required to be guaranteed to be in the center of the centrum during machining, and the accuracy of the inverted measurement is directly influenced. Connect firm together with survey circular cone 3 with total powerstation prism 1 before the use and avoid the pine to take off, survey and establish the bolt hole inward flange clean up that will be surveyed the work piece, avoid having overlap and burr to influence this device and lay, general condition equipment opposite side can not see through, proposes to use the rear intersection method to survey and establish.
When the device is used for measuring the hole position of the vertical surface, the connecting bolt 2 can be unscrewed and directly installed on a threaded hole in the back surface of the prism 1 of the total station for measuring.
To sum up, the utility model discloses a bolt precision measurement positioner utilizes connecting bolt 2 to link together circular cone 3 of surveying and mapping with total powerstation prism 1, put into equipment under test's bolt hole with circular cone 3 of surveying and mapping, circular cone 3 of surveying and mapping can be automatic in the diameter is less than 70mm within range and coincide with bolt hole axis, and simultaneously, recycle level gauge 4 from the area on total powerstation prism 1 and with this measurement positioner leveling, acquire with the position of total powerstation prism 1 center coincidence, thereby obtain the accurate coordinate of bolt hole vertical position through total powerstation prism 1 measurement, acquire the true position of bolt hole.
