下面结合具体实例来说明本发明专利的工作原理,以及操作使用方法。首先确保塔尺外壳1,塔尺卡紧卡2,稳定扶正架4,水准器5,配重10都在正常工作范围内。第一步,平置各个仪器部件,取下T形小销栓12c,将弹簧12b依次安装固定杆12上,根据塔尺13的外形选择相应的塔尺卡紧卡2,将塔尺卡紧卡2压缩弹簧12b后,把T形小销栓12c插在固定杆12的销栓孔12a,依次安装好剩下的三个塔尺卡紧卡2。第二步,将钢丝9通过中心孔11穿出来,根据沉降观测点的位置高度,调节钢丝9的长度,把其系到环形套圈10b的上面,再将六角螺丝10a拧紧到铅锤锥上面的螺孔中。第三步,通过塔尺卡紧卡2压缩弹簧12b,撑开塔尺卡紧卡2后,将塔13缓缓插到塔尺外壳1的塔尺卡紧卡2中,松开塔尺卡紧卡2,让其自动卡紧塔尺13,当塔尺13插进塔尺外壳的底部后,要确保牢固。第四步,缓慢扶正塔尺外壳1,将球形凹槽圆台6的凹槽对准待测的沉降观测点的末端球体的顶部,缓慢放到沉降观测点的球体上,铅锤锥在自重的作用下,会通过钢丝9拉紧等边铝合金架7,并且在铅锤锥自重下会自动调整稳定扶正架的垂直度,使稳定扶正架处于铅直状态,而水准器5此时可检验塔尺是否真正处于铅垂状态,进而使塔尺外壳1铅直状态,也就保证了塔尺的垂直度。此时,测量员可在一个测站的可测点处均设置这样的自动扶正装置,再在仪器旁边观测构、建筑物的每个测点的高程。测量结束后可将塔尺取下,取下塔尺卡紧卡2以及弹簧12b,将其保存好。将六角螺丝10a直接拧下,通过中心孔11取出来即可,在下次测量时直接把六角螺丝10a穿过中心孔11再拧到铅锤锥顶部的螺孔中即可,这样不但减少了测量人数,而且还提高测量效率,提高了测量精度。The working principle and operation method of the patent of the present invention will be described below in conjunction with specific examples. Firstly, make sure that the tower ruler casing 1, the tower ruler clamping clamp 2, the stabilizing centering frame 4, the level 5, and the counterweight 10 are all within the normal working range. The first step is to place all the instrument components horizontally, remove the T-shaped small pin 12c, install the spring 12b on the fixed rod 12 in turn, select the corresponding tower ruler clamping card 2 according to the shape of the tower ruler 13, and clamp the tower ruler After the card 2 compresses the spring 12b, the T-shaped small pin 12c is inserted into the pin hole 12a of the fixed rod 12, and the remaining three tower ruler clamping cards 2 are installed in sequence. The second step is to pass the steel wire 9 through the central hole 11, adjust the length of the steel wire 9 according to the height of the settlement observation point, tie it to the top of the annular ferrule 10b, and then tighten the hexagonal screw 10a to the plumb cone in the screw hole. The third step is to compress the spring 12b through the clamping card 2 of the tower ruler. After the clamping card 2 of the tower ruler is opened, the tower 13 is slowly inserted into the clamping card 2 of the ruler shell 1, and the clamping card is released. Tighten clamp 2, allow it to clamp the tower ruler 13 automatically, after the tower ruler 13 is inserted into the bottom of the tower ruler shell, ensure firmness. The fourth step is to slowly straighten the tower ruler shell 1, align the groove of the spherical groove round table 6 with the top of the end sphere of the settlement observation point to be measured, and slowly put it on the sphere of the settlement observation point, and the plumb cone is placed at the center of its own weight. Under the action, the equilateral aluminum alloy frame 7 will be tightened by the steel wire 9, and the verticality of the stabilizing centralizing frame will be automatically adjusted under the deadweight of the plumb cone, so that the stabilizing centralizing frame is in a vertical state, and the level 5 can be inspected at this time Whether the tower chi is really in a plumb state, and then the tower chi shell 1 is made to be in a plumb state, which ensures the verticality of the tower chi. At this time, the surveyor can set such an automatic righting device at the measurable points of a survey station, and then observe the elevation of each survey point of the structure or building next to the instrument. After the measurement, the tower ruler can be taken off, the tower ruler clamping clip 2 and the spring 12b are taken off, and it is preserved. Unscrew the hexagonal screw 10a directly and take it out through the central hole 11. In the next measurement, directly pass the hexagonal screw 10a through the central hole 11 and then screw it into the screw hole on the top of the plumb cone, which not only reduces the measurement The number of people, but also improve the measurement efficiency, improve the measurement accuracy.
