Description

Technical Field

[0001] The present application relates to the field of auxiliary measuring machines and tools, and in particular to a level-type auxiliary measuring board. Background Art

[0002] The elevation point used in engineering surveying or building settlement observation is a metal part with a curved top, usually buried in concrete or exterior walls with the top exposed, or welded to a steel column. When a precision level is used for leveling, a flat-bottomed indium steel ruler is placed on the elevation point to take a reading. However, when transferring elevation between two points with a large vertical drop, a total station is often used for trigonometric height measurement, which requires a prism to take points. Since its reflection angle cannot be made precise, the accuracy cannot reach the measurement accuracy of a precision level.

[0003] The spherical prism (SMR) is a measurement target dedicated to the 3D laser tracker. The main body is a spherical metal with a diameter of 1.5 inches and a glass reflective prism embedded inside. The spherical prism has the characteristics of small size and high precision. The data measured within the sighting angle range of less than 90° can guarantee the accuracy. When using it for elevation point measurement, the problem of inaccurate reflection angle can be solved, but there will be the problem of instability of point-to-point contact between two arc-shaped objects. When it is adsorbed on the matching flat-bottomed magnetic base, it will still face the problem of shaking, and it cannot be accurately aligned, which affects the measurement accuracy. This is also the reason why trigonometric elevation cannot replace precision leveling measurement. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] See also Figure 1 An embodiment of the present application provides a leveling auxiliary measuring plate, including: an auxiliary measuring plate 1, a leveler, and an adjusting rod.

[0020] The auxiliary measuring board 1 is used to be set at the elevation point and to support the spherical prism. The auxiliary measuring board 1 is made of transparent organic glass. The height of the auxiliary measuring board 1 is between 100mm-150mm, the thickness is between 10mm-20mm, the upper and lower surfaces have straightness requirements, and the finished product is smooth and transparent. The auxiliary measuring board 1 is an isosceles triangle structure. The top angle of the isosceles triangle structure is used to be set at the elevation point. The two bottom angles of the isosceles triangle structure are respectively provided for the installation of two adjustment rods.

[0021] In addition, a fixed magnet 4 is installed on the upper part of the auxiliary measurement board 1, and the fixed magnet 4 is used to adsorb the metal base of the spherical prism. The diameter of the fixed magnet 4 is between 5mm and 10mm. The fixed magnet 4 is installed at the vertex of the isosceles triangle structure. The upper part of the auxiliary measurement board 1 has a fixed sink groove, and the fixed sink groove is used to embed the fixed magnet 4. The fixed sink groove is a circular structure.

[0022] The auxiliary measuring plate 1 has an adsorption magnetic strip 5 on its side, which is used to be adsorbed on the side of the steel column to stabilize the auxiliary measuring plate 1 when measuring the L-shaped elevation point welded on the steel column. The adsorption magnetic strip 5 is installed on the bottom side of the isosceles triangle structure. The auxiliary measuring plate 1 has an adsorption trough on its side, and the adsorption trough is used to embed the adsorption magnetic strip 5.

[0023] The level is used to obtain the horizontality of the auxiliary measuring plate 1. The level is installed on the auxiliary measuring plate 1. The level can be two tube levels 2, and the two tube levels 2 are respectively installed on the two waist sides of the isosceles triangle structure. To this end, both waist sides of the isosceles triangle structure have installation sinks, and the two installation sinks are respectively used to inlay the two tube levels 2. The center lines of the two tube levels 2 are perpendicular to each other. The lengths of the two tube levels 2 are between about 30mm and 40mm. The level can also be a circular level. It should be noted that the tube level 2 is more suitable for the situation where the auxiliary measuring plate 1 has only two adjustment points, and its speed and accuracy are better than the circular level.

[0024] There are two adjusting rods, both of which are vertically installed at the lower part of the auxiliary measuring plate 1 and can move up and down. The two adjusting rods and the elevation points are respectively located at three points of the triangular structure. The two adjusting rods are used to form a triangular stable support structure with the elevation points, and cooperate with the level to realize the horizontal adjustment of the auxiliary measuring plate 1.

[0025] The adjusting rod can be a knob adjustment screw 3, and the knob adjustment screw 3 is threadedly mounted on the auxiliary measuring plate 1. Specifically, an internal threaded through hole is provided at each of the two bottom corners of the auxiliary measuring plate 1, and two knob adjustment screws 3 are respectively threadedly mounted in the two internal threaded through holes to adjust the tube level 2 so that its bubble is centered. It should be noted that the level type auxiliary measuring plate of the present application can be used as a level instrument for leveling various planes after removing the knob adjustment screw 3.

[0026] The horizontal auxiliary measuring plate of the present application is used in conjunction with a spherical prism (SMR) to provide a convenient and fast centering platform for the spherical prism when a three-dimensional laser tracker or total station measures elevation reference points, and to provide a stable prism state, thereby solving the problem that a handheld prism cannot hold the ball stably, thereby affecting the measurement accuracy, thereby improving the measurement accuracy of the three-dimensional laser tracker and total station when measuring elevation points, and broadening the application scope of trigonometric height measurement in engineering measurement and deformation measurement.

[0027] The horizontal auxiliary measuring plate of the present application provides a convenient and fast centering platform for the spherical prism, converts the point-to-point contact of the two arc surfaces into point-to-face contact, and forms a triangular stable platform formed by the elevation point and two knob adjustment screws, which is free from the unstable state of the handheld prism and effectively improves the height measurement accuracy. Moreover, it circumvents the requirement of equal sight distances for front and rear sights in the traditional precision leveling measurement process to a certain extent, and promotes the digital development of precision leveling point measurement.
