Parasol type rotary top technology parameters
The parasol type rotary top is an important tool for engineering technicians and engineers to accurately measure the horizontal displacement of construction items. The parasol type rotary top can also be used to measure the tilt of transmission structures and their anchor lines. The technology of parasol type rotary tops is mainly composed of twisted axis dot finding, rotating arm module, wireless accessory and base plate.
The twisted axis dot finding is mainly composed of horizontal chord, vertical chord and ground bar. The horizontal chord uses the laser beam of side pointing to get the centre point of the rotating axis. The vertical chord uses the precise estimation with ground bar and laser beams, and then gets accurate height of the centre point of rotating axis when the technology of parasol type rotary tops is used.
The rotating arm module is mainly composed of arm poles and arm bushings. It is mainly used to calculate the distance from the central point of the rotating axis to the front centre of the rotating arm module. The arm bushings are connected with the rotating arm module. The arm bushings are used to rotate the arm for precise reading. The total rotation angle of the arm is 90’ relative to the central point of the rotating axis.
The wireless accessory is mainly composed of data acquisition module, GPS module and GMS internal transmission module. The data acquisition module is mainly used to acquire data about the installed rotating arms. The GPS module is mainly used to process the high precision positioning data on the ground. The GMS internal transmission module is mainly used to receive the position information of the rotating arms.
The base plate is mainly composed of vertical pole, horizontal pole and torsion bar. It is mainly used to make sure the stable operation of the technology of parasol type rotary tops. The vertical pole is used as the base to support the parasol type rotary top. The horizontal pole is used to keep the vertical pole in a stable position. The torsion bar is mainly used to compensate the small rotation mistake of the vertical pole.
In conclusion, the parasol type rotary top technology parameter is mainly composed of twisted axis dot finding, rotating arm module, wireless accessory and base plate. These four technologies are the main components of working together to ensure the accurate measurement of horizontal displacement of items and tilt of transmission structure and anchor lines. The parasol type rotary top technology has been widely used in engineering and construction projects.
