It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It is to be further noted that, for the convenience of description, only some but not all of the elements related to the present invention are shown in the drawings.

Referring to fig. 1-7, the present embodiment provides a rotary lidar mapper.

As shown in fig. 1, 2 and 3, the device comprises a base 1, a motor 2, a zero position switch 3, a mounting rack 4, a turntable 5, a laser radar 6 and a steering engine 7.

The base 1 is a square shell and is provided with a closed chamber, so that dust can be well prevented, and an internal electric device is protected.

The middle of the rotary table 5 is provided with a through hole, and the rotary table 5 is rotatably arranged above the base 1.

The motor 2 is a stepping motor and is provided with a through hole penetrating through an output shaft and a motor body, the motor 2 is arranged inside the base 1, and the output shaft of the motor is coaxially connected with the rotating shaft of the rotating disc 5.

The mounting rack 4 is arranged on the turntable 5, the mounting rack 4 is a U-shaped plate, one side of the U-shaped plate is provided with a laser radar 6, the other side of the U-shaped plate is provided with a steering engine 7,

the rotary output shaft of the steering engine 7 is provided with a rotary arm 71, the rotary arm 71 is provided with a dust removal strip 72, the rotary arm 71 can rotate around the laser radar 6 for a circle, and in the rotating process, the dust removal strip 72 scrapes dust on the surface of the laser radar 6, so that the laser radar is cleaned and prepared for scanning.

The steering engine 7 can be composed of a servo motor, a transmission mechanism and a control circuit. The function of steering wheel 7 in this application is before laser radar scanning measurement, earlier by instruction steering wheel 7 drive rocking arm 71 around laser radar 6 rotatory a week, dust removal strip 72 clears up the laser radar surface, then drives rocking arm 71 and rotates back to initial position.

The steering gear 7 may be another rotating motor, a rotating cylinder, or a motor capable of performing a rotating operation. If the air cylinder is a rotary air cylinder, the rotating arm 71 is arranged on a rotating seat of the air cylinder, and the rotating arm 71 is driven to rotate by the rotary air cylinder.

As shown in fig. 4 and 5, the mounting frame 4 is a U-shaped mounting plate, and a lower bottom plate thereof is provided with an elongated slot 42, a first threading hole 41 is provided on the lower bottom plate, a second threading hole 43 is provided on a side surface of the bottom plate, and the first threading hole 41 and the second threading hole 43 are communicated with the elongated slot 42.

As shown in FIG. 2, when the mounting bracket 4 is mounted on the turntable 5, an elongated channel is formed between the elongated slot 42 and the turntable 5. The electric wire of the laser radar 6 enters the elongated slot 42 through the first threading hole 41, then enters the through hole of the motor 2 through the through hole of the turntable 5, and finally enters the inside of the base 1.

Alternatively, a simple way of providing the mounting 4 with through holes is not shown. The line of laser radar and the line of steering wheel converge to middle hole department, pass the through-hole of motor, enter into inside the base.

The control line of the steering engine 7 sequentially passes through the second threading hole 43, enters the elongated slot 42, passes through the through hole of the turntable 5, enters the through hole of the motor 2, and finally enters the inside of the base 1.

According to the wiring mode, the wire is positioned on the rotating center, the rotating and twisting of the wire are reduced to the maximum extent, and the damage to the wire in the repeated rotating process of the laser radar is reduced. Meanwhile, the electric wire is hidden and protected and is not exposed outside, and damage to the electric wire is reduced.

As shown in fig. 2, the stepping motor driver 21 and the switch 22 are installed inside the base 1, which is both beautiful and practical.

As shown in fig. 2 and 7, the zero-position switch 3 is installed inside the base 1, and the paddle 32 of the zero-position switch 3 extends out of the upper outer position of the base 1 through a hole formed in the base 1.

The rotary disk 5 is provided with a collision block, the collision block touches the dial piece 32 from the right side position of the dial piece 32 as shown in fig. 7, the zero switch 3 obtains a signal, and the zero position is confirmed.

The technical problems of 360-degree rotation and physical zero limit are solved.

Because the laser radar needs to rotate 360 degrees in the scanning and measuring process, the accuracy of measurement can be ensured only by accurately ensuring that the laser radar scans 360 degrees, and if the accuracy is less than 360 degrees, the volume of a part of objects to be measured is missed. Therefore, a zero position switch is required to determine the initial position of the laser radar rotation, and then a 360-degree rotation angle is ensured through the stepping motor.

On the other hand, the zero position switch also plays the spacing effect of physics, prevents that the carousel from changeing many rings, twisting bad cable. As shown in fig. 7, after the turntable rotates 360 degrees, the striking block will touch the pick 32 from the left position to perform a limiting function, thereby preventing overshoot.

Because the elastic sheet with good elasticity of the shifting piece 32 can play a role in limiting on one hand, but the elasticity has a certain limit, and the size of the hole formed in the rotating disc 5 can limit the moving space of the shifting piece. On the other hand, can give the surplus in certain space again, this surplus can guarantee to bump after the piece contacts the shell fragment, if the carousel does not reach 360 degrees rotations the time, can continue to rotate a small angle forward, until accomplishing 360 degrees. After 360 degrees, the stepping motor rotates back to the zero position, that is, the touching block touches the shifting piece 32 from the right side position of the shifting piece 32.

As shown in fig. 7, the blade 32 of the zero position switch, i.e. the limit switch, has a certain elasticity.
