Composite level measuring tripod with single leg and double legs

technical field

The invention relates to a measurement auxiliary device, in particular to a single-leg and double-leg measuring tripod for a composite level with simple structure, easy operation and the ability to ensure the stability of the composite level.

Background technique

The Chinese patent with the patent application number 201220611636.6 discloses a "composite level combined with a ruler and meter for dual observation" (hereinafter referred to as a composite level). Its structure is to have a cylindrical ruler and a level. A leveling staff parallel to the axis of the cylindrical scale body and an observation unit that can slide up and down are fixed on the same cylindrical surface. The collimating axis of the measuring device is perpendicular to the axis of the cylindrical ruler. When leveling, it is necessary to place the lower end of the cylindrical body (leveling staff) on the auxiliary ruler pad, and at the same time use a tripod to fix the cylindrical body (leveling staff), and use the observation level to place the cylindrical body (leveling staff) Ruler) leveled, and then observe... . This patent application places the level on the leveling staff for the first time, realizing the integration of the leveling unit and the leveling staff. The dual observation principle can be used to change the three-point configuration of the traditional leveling device into a two-point configuration, and realize the synchronization of the two systems Observation overcomes the deficiencies in the prior art. The Chinese utility model patent with the patent number of 201220373858.9 discloses a "clip-type measuring tripod", which changes the outer base of the traditional tripod from a flat plate (cloud platform structure) to a ring (clip-type structure), For the first time, a special measuring tripod is provided for the composite level (and the measuring ruler), which improves the vertical accuracy of the composite level (and the measuring ruler). The Chinese invention patent with the patent number of 201310022381.9 discloses a "clip-type measuring tripod", which further adopts the principle of orthogonal decomposition and adjustment to improve the "clip-type measuring tripod", which speeds up the composite level (and the measuring scale). ) to adjust the speed of the upright state. The Chinese invention patent with the patent number 201610159164.8 discloses a "measurement tripod that can precisely adjust the angle of the scale", which has a scale fixture and an annular base with an opening. The ruler clamps are connected, and there are a top spring on one side of the vertical axis and a horizontal top wire fixed on the ring base on the other side of the vertical axis between the ring base and the scale clamp. The base is connected with three legs (three legs), two legs (two legs) or one leg with two legs. Although the horizontal rotation problem of the composite level (and the measuring ruler) is solved, the composite level (and the measuring ruler) can be accurately faced (aimed) at the opposite composite level. However, the following deficiencies have been found in practice: (1) using three legs (three legs), the three legs and the leveling rod constitute four landing points, it is difficult to adjust the leveling rod leveling, and the practicability is poor; (2) using double legs (Double outriggers), although it can ensure the stability of the composite level, the operation is complicated, and the surveyor's feet cannot move, which is time-consuming and laborious; (2) If the above-mentioned single-leg and double-leg structure is adopted, although the operation is simple, the stability is poor , affecting the precision of the compound level, and even unable to meet the measurement requirements.
