Abstract
The utility model relates to a level measuring prism. The use of a total station and the reflecting prism that can accurately measure the horizontal distance and altitude difference can be used for solving the problem that the use of the total station and the existing reflecting prism can only accurately measure the horizontal distance but can not accurately measure the height difference. The level measuring prism consists of a support frame (1), a central axis (2) of the prism, a reflecting prism (3), an aligner (4) and a support base (5) (as shown in the picture). The aligner and the support base form a vertical axis; the central axes of the two prisms form a horizontal axis; the center of the reflecting prism is arranged at the intersection point of the vertical axis and the horizontal axis. The horizontal wire of the cross wire of the telescope of the total station is aligned with the center of the central axis of the prism; the vertical wire is aligned with the center of the aligner; then the center of the cross wire of the telescope of the total station can be aligned with the center of the reflecting prism. The use of the total station and the level measuring prism can be used for accurately measuring not only the horizontal distance but also the height difference.
Description
Technical field
A kind of reflecting prism that uses when the utility model is to use total powerstation to measure, but the not only flat distance of measure water of total powerstation and the utility model used, can also accurately measure the discrepancy in elevation.
Background technology
The reflecting prism that generally uses all accurately can not accurately be measured the discrepancy in elevation in the directed prism center because of total powerstation telescope center of reticule now, causes total powerstation can only accurately measure flat distance, and can not accurately measure the discrepancy in elevation.
Summary of the invention
When measuring in order to overcome total powerstation and existing reflecting prism, can only the flat distance of measure water and can not accurately measure the deficiency of the discrepancy in elevation, the utility model provides a kind of reflecting prism, but the flat distance of measure water not only can also accurately be measured the discrepancy in elevation.
The reason of using existing reflecting prism can not accurately measure the discrepancy in elevation is accurately directed prism center of total powerstation telescope center of reticule.The technical scheme that the invention for solving the technical problem adopted is: by centralizer and bearing form Z-axis, the two prisms central shaft forms transverse axis, the reflecting prism center occupy on the intersection point of Z-axis and transverse axis.As long as the center of the center of total powerstation telescope crosshair horizontal hair directed prism central shaft, vertical hair aligning centralizer, then total powerstation telescope center of reticule has just accurately been aimed at the center of reflecting prism during measurement.
The beneficial effects of the utility model are, when using total powerstation and the utility model to measure, but both flat distances of measure water can accurately be measured the discrepancy in elevation again, has further developed the function of total powerstation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the surface structure synoptic diagram of an embodiment of the utility model; Fig. 2 is the connection diagram of prism pedestal and support.
Among the figure: 1. support, 2. prism central shaft, 3. reflecting prism, 4. centralizer, 5. bearing, 6. prism pedestal, 7. pedestal set bolt, 8. plastic casing, 9. plastic mattress, 10. clamp nut.
Support is configured to by two " U " types that the width of putting is not waited, and is the skeleton of level range finder prism, and boring, tapping on support are to fix other parts.
Centralizer is positioned at the upper middle position of support, and the latter half is from threaded, with the support wire connection.
Bearing is in the lower middle position of support, with centralizer on same perpendicular line, pilot hole is arranged on the support, bearing has pilot pin, the back, location is fixed with dormant bolt.
The prism central shaft is rounded, and with the support wire connection, its coupling part car has screw thread, when the side, inner end of prism central shaft is threaded to when flushing with the support medial surface, is fixed on the support with clamp nut (10); In the centre-drilling hole of side, inner end, the tapping of prism central shaft, be used for fixing prism pedestal (6).
Reflecting prism is by being bolted on the prism pedestal, and the prism pedestal is fixed on the prism central shaft by pedestal set bolt (7) (showing among the figure that nothing silk part is plastic) and plastic casing (8), adds plastic mattress (9) between prism pedestal and support.
Like this, two prism central shafts form a horizontal line, and the center by reflecting prism, because of the utility model left-right symmetric, and the also center by reflecting prism of the perpendicular line that forms of centralizer and bearing then; The horizontal line that reflecting prism and prism pedestal also can form around the two prisms central shaft together rotates.
Embodiment
The utility model must be fixed on the centering rod and total powerstation is measured together.
Two level range finder prisms are separately fixed on the centering rod, are called centering rod level range finder prism, they are transferred to contour, before two contour centering rod level range finder prisms are erected at respectively on viewpoint and the backsight point.
Two centering rod level range finder prisms are transferred to contour method is: after total powerstation leveling (need not centering), successively two centering rod level range finder prisms are erected on the same point, and total powerstation telescope center of reticule directed prism center, range finding.If when the discrepancy in elevation reading (VD) that total powerstation is measured equated, then two centering rod level range finder prisms were contour.
Before the measurement, horizontally rotate the level range finder prism earlier, aim at total powerstation, vertical again turn prism pedestal is aimed at the total powerstation telescope to reflecting prism.
When measuring horizontal range, the vertical hair of total powerstation telescope crosshair is aimed at the centralizer center, the vertical final motion screw of turn again, with telescope crosshair horizontal hair slightly to prism central shaft center, range finding, recording level range reading (HD), then horizontal range reading (HD) is exactly the accurate horizontal range at total powerstation Z-axis and centering rod center.
When measuring the discrepancy in elevation, the center of the telescopical crosshair horizontal hair of total powerstation directed prism central shaft, the horizontal fine motion knob of turn total powerstation again, with telescope crosshair vertical hair slightly to the centralizer center, range finding, record discrepancy in elevation reading (VD), then discrepancy in elevation reading (VD) is exactly the accurate discrepancy in elevation at total powerstation transverse axis and level range finder prism center.
If when the while flat distance of measure water and the discrepancy in elevation, earlier the center of the telescopical crosshair horizontal hair of total powerstation directed prism central shaft, the horizontal fine motion knob of turn total powerstation again, the vertical hair of total powerstation telescope crosshair is aimed at the centralizer center, range finding, recording level range reading (HD) and discrepancy in elevation reading (VD).Then horizontal range reading (HD) is exactly the accurate horizontal range at total powerstation Z-axis and centering rod center, and discrepancy in elevation reading (VD) is exactly the accurate discrepancy in elevation at total powerstation transverse axis and level range finder prism center.
