技术领域 technical field
本发明涉及一种水准测量装置，特别是一种水准尺垂直度校正架。 The present invention relates to a leveling device, in particular to a leveling bar verticality correction frame.
背景技术 Background technique
水准尺是水准测量中的重要工具，在使用过程中必须确保其处于竖直状态，以保证测量精度，但由于受到震动、搬运、碰撞等因素的影响以及长时间的使用，致使水准尺的圆水准气泡虽然整平，杆体仍不竖直，从而影响测量成果的精度。因此，在使用水准尺之前，必须对其进行严格校正，以使其圆水准气泡整平时而杆体处于铅直状态。传统的校正方法是以水准尺为中心在视线互成90°方向上设置两台经纬仪或全站仪，校正人员在两名观测仪器人员的同时指挥下使水准尺在两台仪器视线方向都保持铅直，然后调整水准尺上的圆水准器校正螺丝使气泡居中,这样要反复几次才可将水准尺垂直度完全校正好。这种方法需要在一定空间内同时操作两台经纬仪或全站仪,至少需要3名检校人员才能作业，因此该校正方法繁琐，速度慢，占用空间大，不易操作、效率低。 The leveling rod is an important tool in leveling measurement. It must be in a vertical state during use to ensure measurement accuracy. However, due to the influence of vibration, handling, collision and other factors and long-term use, the circle of the leveling rod will Although the level bubble is leveled, the rod body is still not vertical, which affects the accuracy of the measurement results. Therefore, before using the leveling rod, it must be calibrated strictly so that the rod body is in a vertical state when the circular leveling bubble is leveled. The traditional calibration method is to set up two theodolites or total stations in the direction of 90° line of sight at the center of the leveling rod, and the calibration personnel will keep the leveling rod in the line of sight direction of the two instruments under the command of two observation instrument personnel at the same time. Then adjust the circular level correction screw on the leveling rod to center the bubble. It takes several repetitions to correct the verticality of the leveling rod completely. This method needs to operate two theodolites or total stations at the same time in a certain space, and at least three calibration personnel are required to operate. Therefore, the calibration method is cumbersome, slow, takes up a lot of space, is not easy to operate, and has low efficiency.
