Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping instruments, in particular to a surveying and mapping base for automatic leveling and a leveling method. Background Art

[0002] Automated surveying and unattended surveying have become the development trend in the surveying and mapping field. At present, large-scale terrain, cadastral and other surveying have basically been realized by drones. However, in some urban built-up areas, no-fly zones, some engineering surveys, underground projects, dangerous places that need to be surveyed and mapped, and other areas or fields where drones cannot be used, total stations, three-dimensional laser scanners and other instruments are still the main ones. If you want to realize unmanned automated operation or remote operation of these surveying and mapping instruments, the first problem that must be solved is the automatic and precise leveling of the instruments; however, when using existing surveying and mapping devices, it is usually necessary to manually level the three machine base screws, making the leveling angle difficult to control and inconvenient to operate. When the operator adjusts the height of the surveying instrument, the angle often changes, which increases the workload of adjusting the height and angle of the surveying instrument, and its bracket is not easy to retract, occupies a large space, and is inconvenient to carry. Summary of the invention

[0003] The purpose of the present invention is to address the deficiencies in the above-mentioned prior art and provide a surveying and mapping base and a leveling method for automatic leveling, so as to solve the technical problem that the existing devices require a lot of time and effort to manually adjust the instrument. A convenient and relatively economical surveying and mapping base is provided to realize the precise automatic leveling function of the surveying and mapping instrument.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] A surveying and mapping base for automatic leveling, comprising an upper base and a lower base, wherein the upper base is provided with an inclination sensor and a plurality of evenly distributed card slots, and the lower base is provided with a control circuit board, a battery, a plurality of sleeves and a plurality of transmission boxes;

[0006] The bottom end of the screw rod is movably arranged in the sleeve, the top end of the screw rod is connected to a clamping block, the clamping block is movably arranged in the clamping groove, a large gear is placed on the top end of the sleeve, an internal threaded through hole is arranged on the large gear, the screw rod is screwed into the internal threaded through hole, a motor is connected to the transmission box, a small gear is connected to the rotating shaft of the motor, and the small gear is meshed with the large gear.

[0007] The battery is connected to the tilt sensor, the control circuit board and the motor respectively through wires, and the control circuit board is connected to the control tilt sensor and the motor respectively through control lines.

[0008] A clamping spring is arranged in the clamping groove, the clamping block is a spherical ball, and the clamping spring is clamped at the connection between the clamping block and the screw rod.

[0009] The top surface of the upper base is also provided with a countersink and a circular level, and the inclination sensor is placed in the countersink.

[0010] There are three card slots, three sleeves and three transmission boxes. The card slots are evenly distributed on the upper base, and the sleeves and the transmission boxes are evenly distributed on the lower base.

[0011] A leveling method for a surveying and mapping base for automatic leveling comprises the following steps:

[0012] S1. Screw the screw into the internal threaded hole of the large gear, insert the bottom end of the screw into the sleeve, and the large gear and the small gear mesh with each other;

[0013] S2. Place the upper base on the lower base, insert the clamping block into the clamping slot, then place the clamping spring in the clamping slot, clamp the clamping spring at the connection between the clamping block and the screw rod, and place the upper base on the lower base;

[0014] S3. The inclination sensor transmits the tilt data of the upper base to the control circuit board. The control circuit board controls the three motors to rotate. The motor drives the small gear to rotate. The small gear drives the large gear to rotate. The rotation of the large gear drives the lead screw to rise and fall until the upper base is flat and the motor stops rotating.

[0015] The beneficial effects of the present invention are:

[0016] 1. The motor drives the large gear to rotate through the small gear, and the internal threaded through hole of the large gear rotates relative to the screw rod, thereby driving the screw rod to move up and down. The block on the screw rod contacts the upper base, and finally adjusts the flatness of the upper base, thereby completing the automatic adjustment of the surveying and mapping angle, solving the technical problem that the existing device needs to spend a lot of time and energy to manually adjust the instrument. The convenient and relatively economical surveying and mapping base realizes the precise automatic leveling function of the surveying and mapping instrument.

[0017] 2. The circular level makes it easy to observe the horizontal situation with the naked eye. By placing the inclination sensor in the countersunk hole, the top surface of the upper base is ensured to be flat, which is convenient for placing the surveying and mapping instruments.
