背景技术Background technique
专利申请号为201220611636.6的中国专利，公开了一种“对偶式观测用尺仪合一复合水准仪”（以下简称复合水准仪），其结构是设有柱形尺体及水准器，在柱形尺体的同一柱面上固定有与柱形尺体轴线平行的水准标尺及可上下滑动的观测单元，所述观测单元有相互固定连接的对方高度信号测定器和本方高度信号测定器，对方高度信号测定器的视准轴与柱形尺体轴线垂直。水准测量时，需要将柱形尺体（水准标尺）的下端置于辅助尺垫上，同时需要使用三腿脚架固定柱形尺体（水准标尺），通过观测水准器等将柱形尺体（水准标尺）整平后，再进行观测……。此专利申请首次将水准仪安置在水准标尺上，实现了水准仪和水准标尺的一体化，可采用对偶观测原理，将传统水准测量装置的三点配置改为两点配置，并且实现了双系统的同步观测，克服了现有技术存在的不足。专利号为201220373858.9的中国实用新型专利，公开了一种“套夹式测量脚架”，将传统脚架的外基座由平板状（云台式结构）更改为环状（套夹式结构），首次为复合水准仪（及测量标尺）提供了专用的测量脚架，提高了复合水准仪（及测量标尺）的直立垂直的精确度。专利号为201310022381.9的中国发明专利，公开了一种“抱夹式测量脚架”，进一步采用正交分解调整原理对“套夹式测量脚架”做了改进，加快了复合水准仪（及测量标尺）的直立状态的调整速度。专利号为201610159164.8的中国发明专利，公开了一种“可精确调节标尺角度的测量脚架”，有标尺夹具及具有开口的环状基座，环状基座的中部内侧面通过竖向转轴与标尺夹具相接，在环状基座与标尺夹具之间相接有有位于竖轴一侧的顶簧及位于竖轴另一侧且固定在环状基座上的横向顶丝，与环状基座相接有三支脚（三支腿）、二支脚（二支腿）或单腿双支脚。虽然解决了复合水准仪（及测量标尺）的水平转动问题，使复合水准仪（及测量标尺）可精确面向（瞄准）对方复合水准仪。然而，实践中发现存在以下不足：（1）采用三支脚（三支腿），三支脚与水准标尺构成四个着地点，难以调节水准标尺整平，实用性较差；（2）采用双支脚（双支腿），虽然可保证复合水准仪的稳定性，但操作复杂，测量员双脚不能移动，费时费力；（2）若采用所述单支腿双支脚结构，虽操作简单，但是稳定性差，影响了复合水准仪的精密性，甚至不能满足测量要求。The Chinese patent application number 201220611636.6 discloses a "dual observation ruler-instrument integrated compound level" (hereinafter referred to as the compound level), which is structured as a cylindrical ruler and a leveler, a leveling rod parallel to the axis of the cylindrical ruler and an observation unit that can slide up and down are fixed on the same cylindrical surface of the cylindrical ruler, and the observation unit has a mutually fixedly connected opponent's height signal measuring device and a local height signal measuring device, and the sighting axis of the opponent's height signal measuring device is perpendicular to the axis of the cylindrical ruler. When leveling, the lower end of the cylindrical ruler (leveling rod) needs to be placed on an auxiliary ruler pad, and a tripod needs to be used to fix the cylindrical ruler (leveling rod), and the cylindrical ruler (leveling rod) needs to be leveled by observing the leveler, etc., and then observation can be carried out... This patent application places the level on the leveling scale for the first time, realizing the integration of the level and the leveling scale. The dual observation principle can be adopted to change the three-point configuration of the traditional leveling device to a two-point configuration, and realize the synchronous observation of the dual system, overcoming the shortcomings of the existing technology. The Chinese utility model patent with patent number 201220373858.9 discloses a "clip-type measuring tripod", which changes the outer base of the traditional tripod from a flat plate (pan-type structure) to a ring (clip-type structure), and provides a special measuring tripod for the compound level (and measuring scale) for the first time, improving the vertical accuracy of the compound level (and measuring scale). The Chinese invention patent with patent number 201310022381.9 discloses a "clamp-type measuring tripod", and further adopts the orthogonal decomposition adjustment principle to improve the "clip-type measuring tripod", which speeds up the adjustment speed of the upright state of the compound level (and measuring scale). The Chinese invention patent with the patent number of 201610159164.8 discloses a "measuring tripod with accurate adjustment of the scale angle", which has a scale fixture and an annular base with an opening. The inner side of the middle part of the annular base is connected to the scale fixture through a vertical rotating shaft. There is a top spring located on one side of the vertical axis and a horizontal top screw located on the other side of the vertical axis and fixed on the annular base between the annular base and the scale fixture. There are three legs (three legs), two legs (two legs) or one leg and two legs connected to the annular base. Although the horizontal rotation problem of the compound level (and the measuring scale) is solved, the compound level (and the measuring scale) can accurately face (aim at) the other compound level. However, in practice, the following deficiencies have been found: (1) The three legs (three supports) and the leveling rod form four landing points, which makes it difficult to adjust the leveling rod to be level, and the practicality is poor; (2) The double legs (double supports) can ensure the stability of the compound level, but the operation is complicated, the surveyor's feet cannot move, and it is time-consuming and laborious; (2) If the single-leg double-leg structure is adopted, although the operation is simple, the stability is poor, which affects the precision of the compound level and may even fail to meet the measurement requirements.

What is different from the prior art is that a transverse support member 6 is fixed to the outer side surface of the middle part of the annular base 2, and the transverse support member 6 is two first fixed plates 6-1 which are parallel to each other and perpendicular to the outer side surface of the middle part of the annular base 2. The first transverse rotating shaft 7 vertically passes through the two first fixed plates 6-1 and is rotatably connected to the first fixed plate 6-1. The first transverse rotating shaft 7 is threadedly connected to the upper part of the first movable block 8, so that the first movable block 8 can move axially along the first transverse rotating shaft 7 and rotate axially around the first transverse rotating shaft 7. The lower part of the first moving block 8 is threadedly connected with the second transverse rotating shaft 9, and the horizontal projections of the first transverse rotating shaft 7 and the second transverse rotating shaft 9 are axially perpendicular to each other.

测量操作过程如图4所示：将测量标尺置于标尺夹具1内并通过固定件将标尺固定。将测量标尺底部放在水准测量标志点上，使两个支脚12位于地面，通过调整支脚12的水平位置使测量标尺大致处于垂直状态，然后通过第一横向转轴7与第二横向转轴9的转动，使测量标尺精确处于垂直状态，再微调顶丝5，使垂直的测量标尺沿竖轴3水平转动，顶丝5与弹簧4共同作用使测量标尺精确面向对方的复合水准仪。The measuring operation process is shown in FIG4 : the measuring ruler is placed in the ruler fixture 1 and fixed by the fixing part. The bottom of the measuring ruler is placed on the leveling measurement mark point, so that the two legs 12 are located on the ground, and the measuring ruler is roughly in a vertical state by adjusting the horizontal position of the legs 12, and then the measuring ruler is precisely in a vertical state by rotating the first horizontal rotating shaft 7 and the second horizontal rotating shaft 9, and then the top screw 5 is fine-tuned to make the vertical measuring ruler rotate horizontally along the vertical axis 3, and the top screw 5 and the spring 4 work together to make the measuring ruler accurately face the other side of the compound level.
