Embodiment 1

[0056] Such as figure 1 and figure 2 As shown, an automatic leveling system for a photoelectric turntable includes a base 1, an electric control system 2 arranged on the base 1, an adjustment platform 3 arranged above the base 1, and an elastic body arranged on the circumferential side of the adjustment platform 3. The sealing ring 4, the sealing shell 5 between the circumferential side of the elastic sealing ring 4 and the circumferential side of the base 1, the three electric adjustment leg assemblies 6 whose circumference is evenly distributed between the base 1 and the adjustment platform 3; the base 1 , the sealing shell 5, the elastic sealing ring 4 and the adjustment platform 3 form a hollow shell, and the electric control system 2 is located in the hollow shell.

[0057] The adjustment platform 3 is also provided with an electrical interface 32 and a plurality of general-purpose mechanical interfaces 31 along the circumference. The plurality of mechanical interfaces ...

Embodiment 2

[0088] The difference from Embodiment 1 is that there are four electrically adjustable outrigger assemblies 6, which can be adjusted by using the connected two electrically adjustable outrigger assemblies 6 as fulcrums and the remaining two electrically adjustable outrigger assemblies 6 to form surface-to-face adjustment. , this adjustment method is more convenient.

Embodiment 3

[0090] The difference from Embodiment 1 is that both the inclination sensor 7 and the electronic level 8 are arranged on the photoelectric turntable, and the flatness of the photoelectric turntable is directly monitored by the inclination sensor 7 and the electronic level 8, so that the leveling accuracy of the photoelectric turntable is higher.

Abstract

The invention provides an automatic leveling system and method for a photoelectric rotary table. The problems that an existing leveling mechanism is poor in leveling precision, long in leveling time,low in working efficiency and prone to being interfered by environmental factors are solved. The leveling system comprises a base, an electric control system arranged on the base, a leveling platformarranged above the base, an elastic sealing ring arranged on the periphery of the leveling platform, a sealing shell arranged between the periphery of the elastic sealing ring and the periphery of thebase, and at least three electric adjusting support leg assemblies circumferentially and evenly distributed between the base and the leveling platform. The electric adjusting support leg assemblies comprise installation frames and motors arranged on the base, adjusting screw rods connected with outputs of the motors, translation wedge blocks sleeving the adjusting screw rods, lifting wedge blocksarranged on the translation wedge blocks, spherical adjusting units arranged on the lifting wedge blocks, guide rods of which the lower ends are fixedly connected with a leveling bottom plate, and the upper ends are connected with locking pieces, and pre-tensioning springs sleeving the guide rods. The electric control system is used for collecting measurement data of a tilt angle sensor and an electronic level meter on the leveling platform and controlling the motors to act.

Description

technical field [0001] The invention relates to a leveling system and a photoelectric turntable, in particular to an automatic leveling system for a photoelectric turntable and an automatic leveling photoelectric turntable. Background technique [0002] In the field of photoelectric measurement, in order to meet the requirements of high-precision measurement pointing, the photoelectric turntable needs to provide a high-precision horizontal reference before working, that is, to achieve leveling through the leveling mechanism. According to the principle of determining a plane by three points, most leveling mechanisms use three-point support for leveling. The existing leveling mechanism needs to be built on the first-level coarse leveling foundation ring (a rigid ring is pre-embedded in the concrete foundation, and the upper surface of the rigid ring provides a relatively flat first-level rough plane datum), leveling There are generally three kinds of mechanism schemes: the fi...
