Abstract
The utility model belongs to the field of RTK topographic survey, in particular to a stabilization auxiliary device based on RTK special surface survey, which comprises a support flat plate, a universal bearing and a measuring rod fixing device; the measuring rod fixing device comprises a sleeve, a rod support and a pipe hoop; the top of the sleeve is provided with an opening, and the bottom of the sleeve is fixedly connected with the rod support; the pipe hoop is fixedly connected above the sleeve; the base of the universal bearing is fixed on the upper surface of the support flat plate; and the transmission end at the top of the universal bearing is fixedly connected with one end of the rod support far away from the sleeve. The device of the utility model can better keep the RTK measuring rod always on the ground surface when using RTK measurement, and avoid artificial measurement error caused by sinking of the measuring rod under the soft ground state; meanwhile, the measuring rod can rotate freely through the universal bearing.
Description
Technical Field
The utility model belongs to RTK topographic survey field, concretely relates to stabilize auxiliary device based on special earth's surface of RTK is measured.
Background
RTK (Real-time kinematic) has extensive application in topographic survey, but in some special earth surfaces (sandy beach, mire, desert, etc.), because RTK measuring stick adds the instrument dead weight reason, can appear sagging phenomenon, leads to the measurement to appear the error.
The prior art lacks devices and equipment which can solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to not enough among the prior art, designed a stable auxiliary device based on special earth's surface of RTK is measured.
The specific contents are as follows:
a stabilization auxiliary device based on RTK special earth surface measurement is different from the prior art in that the device comprises a support flat plate, a universal bearing and a measuring rod fixing device;
the measuring rod fixing device comprises a sleeve, a rod support and a pipe hoop; the top of the sleeve is provided with an opening, and the bottom of the sleeve is fixedly connected with the rod support; the pipe hoop is fixedly connected above the sleeve;
the base of the universal bearing is fixed on the upper surface of the support flat plate; and the transmission end at the top of the universal bearing is fixedly connected with one end of the rod support far away from the sleeve.
The support flat plate is characterized in that: the system is portable, and supports the whole system to keep the RTK instrument stable on a special ground surface (sand beach, muddy, desert and the like) without sinking. The universal bearing has a supporting function and supports the fixing device of the upper measuring rod to rotate randomly in all directions. The rod support of the measuring rod fixing device mainly enables the universal bearing and the sleeve to be directly connected together, the sleeve mainly can assist in fixing the measuring rod, and the pipe hoop mainly can be used for fixing the measuring rod.
When the device is used, the bottom of the RTK measuring rod is inserted into the sleeve, the measuring rod is fixed by the pipe hoop and is enabled to rotate in all directions through the universal bearing.
Furthermore, the device also comprises a gradient measuring instrument arranged on the upper surface of the supporting flat plate and used for correcting system errors caused by non-horizontal ground surfaces.
Furthermore, the gradient measuring instrument and the support flat plate are welded into a whole.
Furthermore, the universal bearing and the support flat plate are welded into a whole.
Furthermore, the sleeve, the rod support and the pipe hoop form a whole in a welding mode.
The utility model has the advantages as follows:
the device of the utility model can better keep the RTK measuring rod always on the ground surface when using RTK measurement, and avoid artificial measurement error caused by sinking of the measuring rod under the soft ground state; meanwhile, the measuring rod can rotate freely through the universal bearing; and the system error brought by the non-horizontal earth surface can be corrected by the gradient measuring instrument.
