Detailed ways

The patent of the present invention will be further described below in conjunction with the accompanying drawings. The scope of protection of the patent of the present invention is not limited to the following: Referring to Figures 1-14, a tower ruler self-righting device includes a tower ruler housing 1 and a tower ruler clamping clamp 2 , stabilizing centralizing frame 4, counterweight 10, the length of tower chi shell 1 is identical with the length of the first section of tower chi, is connected with the top vertical welding of stabilizing centralizing frame 4, and the inside both sides of tower chi shell 1 has fixed bar 12. There is a spring 12b on the fixed rod 12, and there is a T-shaped small pin hole 12a at the end. The fixed rod 12 is connected to the side of the clamping card 2 of the tower ruler. There is a vertical strip hole 3 on the back of the tower ruler shell 1. Device 5 is fixed on the front of the stable centralization frame 4 tops, and the hemispherical groove round platform 6 is positioned at the geometric center below the stable centralization frame 4 tops, and is welded together with the stable centralization frame 4 tops, and the top four of the stable centralization frame 4 Four equilateral aluminum alloy frames 7 are respectively drawn downwards from the two corners, and contracted below the top concave groove 6 to form a funnel shape. A round hole 11 is opened in the center of the funnel shape. The counterweight 10 is mainly a plumb cone, and the top is opened. There are screw holes corresponding to the hexagonal screw 10a. The top of the hexagonal screw 10a has an annular ferrule 10b of the same size as the nut. The entire size of the screw 10a and the annular ferrule 10b is 2-3mm smaller than the size of the central hole 11. The annular ferrule 10b is connected to the flexible steel wire 9, the end of the flexible steel wire 9 is an enlarged round table 8, and the flexible steel wire is drawn from the top center of the round table 8, the bottom size of the round table 8 is 4-5mm larger than the size of the center hole 11, and the top size is smaller than the center hole 11 in size 2-3mm.

As shown in Figure 1-5, all parts are fixedly connected except for the part with holes. A tower clamping card 2 is provided on the inner side of the tower ruler shell 1, and a tower ruler clamping card 2 is installed on the upper and lower sides of the inner side of the tower ruler shell 1, as shown in Figure 9-14, which lists commonly used replaceable ones. The shape of the tower ruler clamping card 2 can be set with more different tower ruler clamping clamps 2 according to different tower ruler shapes, as shown in Figure 6-8, each composition of the stabilizing and righting part, the steel wire 9 is connected to the center through the central hole 11 On the annular ferrule 10b, it is connected to the plumb cone by the screw 10a.

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.
