Abstract
A portable prism special for mapping comprises a reflecting prism and a prism rack, the reflecting prism is mounted on the prism rack, characterized in that, the prism special for mapping comprises a prism bolt, a rope thread and a gravity center hammer, the center of the prism bolt is provided with through holes from an end head of the prism bolt to a stud tail end of the prism bolt, a rope thread fixing screw hole is arranged on one side of the prism bolt end head, the rope thread fixing screw hole is communicated with the through holes, one end of the rope thread passes through from the through holes and is screwed into the rope thread fixing screw hole by a screw nail to fix the rope thread on inner walls of the through holes, the prism bolt is rotatingly sleeved in the screw holes at the lower end of the prism rack, and the other end of the rope thread is connected with the gravity center hammer. The utility model has advantages that the prism of is convenient for carrying, the using is convenient, the rope thread can be easily adjusted to be in the vertical state by the hammer gravity center, the measuring data is accurate, and the utility model is an ideal and portable prism special for mapping.
Description
Technical field
The utility model relates to a kind of prism, and the special-purpose prism of particularly a kind of portable mapping is applied to the fields of measurement of total powerstation.
Background technology
At present, employed special-purpose prism is made up of reflecting prism, prism holder and centering rod during the total station survey angle and distance.During measurement, must allow centering rod be in vertical state, sight the target prism with total powerstation then, as long as the light that total powerstation penetrates impinges upon the prism the inside, it just can come out from prism center reflected in parallel automatically, thereby reads measurement data by total powerstation.The shortcoming of this prism is that inconvenience is carried, and is unfavorable for field work, and is difficult in practical operation guarantee that centering rod is in vertical state, very easily causes the data measured inaccurate.
Summary of the invention
The purpose of this utility model is: provides a kind of and is easy to carry, and easy to use, the special-purpose prism of the portable accurately mapping of measurement data, this prism can be in vertical state by the easy adjustment centering rod, is used to overcome the deficiencies in the prior art.
The purpose of this utility model can realize by following technical proposals:
The special-purpose prism of this portable mapping, comprise reflecting prism and prism holder, reflecting prism is installed on the prism holder, it is characterized in that: described special-purpose prism also includes the prism bolt, rope silk and center of gravity hammer, the center of prism bolt is provided with through hole from the termination to its double-screw bolt tail end, a side of prism bolt end is provided with rope silk fixing threaded hole, rope silk fixing threaded hole is connected with through hole, one end of rope silk passes from through hole, and screw in a rope silk fixing threaded hole by screw and will restrict and thread be fixed on the inwall of through hole, prism bolt spinning is in the screw of prism holder lower end, and the other end of rope silk connects the center of gravity hammer.
Prism bolt described in the utility model is a hexagon head bolt.
The equal diameters of rope silk fixing threaded hole described in the utility model and through hole.
The utility model has the advantages that: be easy to carry, easy to use, the center of gravity hammer can be in vertical state by easy adjustment rope silk, and measurement data is accurate, is the special-purpose prism of a kind of desirable portable mapping.

Embodiment
As Fig. 1---shown in 3, the special-purpose prism of this portable mapping, comprise reflecting prism 1 and prism holder 2, reflecting prism 1 is installed on the prism holder 2, it is characterized in that: described special-purpose prism also includes prism bolt 3, rope silk 6 and center of gravity hammer 7, the center of prism bolt 3 is provided with through hole 5 from the termination to its double-screw bolt tail end, a side of prism bolt 3 terminations is provided with rope silk fixing threaded hole 4, rope silk fixing threaded hole 4 is connected with through hole 5, one end of rope silk 6 passes from through hole 5, and screw in a rope silk fixing threaded hole 4 silk 6 of will restrict by screw and be fixed on the inwall of through hole 5, prism bolt 3 spinnings are in the screw of prism holder 2 lower ends, and the other end of rope silk 6 connects center of gravity and hammers 7 into shape.Described prism bolt 3 is a hexagon head bolt.The equal diameters of described rope silk fixing threaded hole 4 and through hole 5.
The special-purpose prism of this portable mapping in use, test out the length of required rope silk earlier with gauge, withdraw from the screw in the rope silk fixing threaded hole 4 then, adjust below, prism bolt 3 terminations and reveal the length of rope silk 6, after treating that it reaches pre-side length, a screw is screwed in a rope silk fixing threaded hole 4, threads 6 be fixed on the inwall of through hole 5 thereby will restrict, last again with prism bolt 3 spinnings in the screw of prism holder 2 lower ends, can prepare to measure.During measurement data,, vertically sagging center of gravity hammer 7 is erected on the institute measuring point position, reads the data of a position then by the operation of total powerstation with hand-held firmly prism.This special use prism uses the rope silk that has the center of gravity hammer to replace the centering rod of original mapping prism, is very easy to keep vertical state, has guaranteed the accuracy of measurement data.
