example

[0031] Such as figure 2 As shown, the centering plate 2 is made of a 10mm thick steel plate with a diameter of 150mm. The center is a centering hole, and a copper sheath 11 is embedded in the center hole. The diameter of the center hole is 20mm. The measuring instrument is centered and fixed through the centering cylinder 1 (or centering ball) and the connecting piece 4, that is, the centering cylinder 1 is provided with external threads, and the measuring instrument is connected by the thread, and then the centering cylinder 1 is inserted into the center of the centering hole, and fix it on the centering plate 2 with the connector 4. In order to ensure the centering effect, during machining, the matching accuracy of the centering cylinder and the center hole, that is, the tolerance of the coaxiality must reach ±0.01mm, and the tolerance of ±0.01mm is negligible in the measurement error. The telescopic rod 8 is made up of two steel pipes with matching inner and outer diamete...

Abstract

The invention discloses a multifunctional forced centering leg bracket which comprises a centering plate, supporting components and fixing components; a central hole is formed in the centering plate, a centering column is arranged in the central hole, a sheath is embedded between the centering column and the central hole, and a connecting piece is arranged at the bottom of the centering column; the axiality tolerance between the centering column and the central hole is plus or minus 0.01 mm; the supporting components comprise three leg bracket rod pieces, each leg bracket rod piece comprises a connecting rod, a fine-tuning structure and a retractable rod, which are connected from top to bottom, and each fine-tuning structure comprises a fine-tuning screw and lock nuts which are located at the two ends of the fine-tuning screw; the fixing components comprises fixing platforms and tapered spiral piles; and the upper ends of the connecting rods are hinged with the centering plate, and the lower ends of the retractable rods are hinged with the fixed platform. The multifunctional forced centering leg bracket has the characteristics of high centering precision, convenience in installation, good stability, high measurement speed, reusability and the like. The multifunctional forced centering leg bracket can be widely used for precise engineering surveying, foundation monitoring, slope monitoring, special engineering monitoring and the like.

Description

technical field [0001] The invention relates to a support for surveying and mapping instruments, in particular to a device for forced centering of surveying and mapping instruments. Background technique [0002] With the acceleration of my country's urbanization process and the improvement of construction standards, there are more and more projects such as high-rise and super high-rise buildings, large-scale stadiums, steel structures, and deep foundation pits. Moreover, the height of buildings is getting higher and higher, the structure of sports venues is becoming more and more complex, the span of steel structures is getting larger and larger, and the foundation pits are getting deeper and deeper, which pose new challenges to traditional engineering surveying and engineering monitoring. How to conduct timely, accurate, fast and reliable measurement and monitoring in the above-mentioned projects is a difficult problem for surveyors. In order to achieve the corresponding m...
