The output shaft of the first driving motor 321 is connected to the transmission shaft 322. The first mounting plate 23 is fixed on the transmission shaft 322. The first mounting plate 23 and the second mounting plate 24 are connected by The connecting piece is detachably connected, a protective frame 26 is fixed on the second mounting plate 24, a laser surveying instrument 25 is installed in the protective frame 26, the laser surveying instrument 25 has a first protruding end 251, the first protruding end 251 has a step portion 252, a rotating cover 261 is hinged on the protective frame 26, a locking device is installed at the bottom of the first protruding end 251, the rotating cover 261 is fixed on the step portion 252 of the first protruding end 251 and abuts against the locking device, so as to fix the rotating cover 261;

[0025] The rotating cover 261 has an annular protection frame 262 , and a buffer protection pad 2621 is provided inside the annular protection frame 262 . The laser surveying and mapping instrument 25 has a surveying and mapping camera 253 , and the surveying and mapping camera 253 is limit-connected inside the annular protection frame 262 and abuts against the buffer protection pad 2621 .

[0026] By adopting the above structure, by adding a lifting box 31 and an observation box 32, it is beneficial to quickly and automatically drive the laser mapper 25 to lift up or down. At the same time, the first drive motor 321 drives the transmission shaft 322 to rotate, and the rotating seat 22 located on the base 21 is marked with an angle scale ring 221. When adjusting the angle of the laser mapper 25, the user can accurately adjust various horizontal rotation angles to prevent errors during adjustment. When the device is not in use or is being transported, the rotating cover 261 hinged on the protection frame 26 can be rotated to cover the mapping camera 253 of the laser mapper 25. The mapping camera 253 of the laser mapper 25 is protected by the annular protection frame 262. At the same time, a buffer protection pad 2621 is added, which is beneficial to better and effectively protect the laser mapper 25 when it is transported and not in use, greatly reducing the probability of damage to the laser mapper 25 and extending the service life of the device.

[0027] Specifically, if Figures 1 to 5As shown, the locking device includes a locking block 41, a first support rod 42, a second spring 43, a second support rod 44, a mounting frame 45 and a lifting button 46. The mounting frame 45 is mounted at the bottom of the first protruding end 251. A first through slot 451 is provided in the mounting frame 45. A second through slot 452 is provided on the first protruding end 251. The first through slot 451 is communicated with the second through slot 452. The lifting button 46 is mounted in the first through slot 451 of the mounting frame 45. The lifting button 46 is fixedly connected to the second support rod 44. One side of the second support rod 44 is connected to the second spring 43 located in the second through slot 452, and the other side is connected to the first support rod 42. A locking block 41 is fixed on the first support rod 42, and one end of the locking block 41 abuts against the rotating closing cover 261.

[0028] With the above structure, when it is necessary to rotate the rotating cover 261 and cover the rotating cover 261 on the mapping camera 253 of the laser mapping instrument 25, the user pulls the lifting button 46 downward in advance. When the lifting button 46 moves downward, it drives the second support rod 44 downward. At this time, the second spring 43 contracts, and the second support rod 44 is fixed to the first support rod 42, thereby driving the locking block 41 on the first support rod 42 to move downward. At this time, the locking device is unlocked, and the rotating cover 261 can be flipped to the step portion 252 of the first protruding end 251. Then the user releases and then lifts the lifting button 46 upward, the second support rod 44 moves upward, the second spring 43 resets, and drives the locking block 41 on the first support rod 42 to move upward to a position higher than the step portion 252. Then the rotating cover 261 abuts against the locking block 41 to complete the locking.

[0029] By adding a locking device, the rotating cover 261 is locked, which is conducive to secure fixation, and the locking and unlocking methods are more convenient and quick. At the same time, it is conducive to effectively protecting the laser mapper 25 when it is transported and not in use, greatly reducing the probability of damage to the laser mapper 25, extending the service life of the device, and making the structure more stable.

[0030] like Figures 1 to 5 As shown, a plurality of first threaded holes are arranged around the first mounting plate 23 , and a plurality of second threaded holes are arranged around the second mounting plate 24 .

[0031] The connecting pieces on the first mounting plate 23 and the second mounting plate 24 are fixed by passing through and threading the first threaded hole and the second threaded hole, which is convenient for assembly and disassembly and securely fixed.

[0032] like Figures 1 to 5As shown, the support mechanism includes a central tube 51 located at the bottom center of the lifting box 31 and a plurality of fixed legs arranged with the central tube 51 as the central circumference, the fixed legs are hinged with a third support rod 521, the third support rod 521 is connected with a telescopic rod 522, one end of the telescopic rod 522 is connected to the third support rod 521, and the other end is connected to the grounding member. The third support rod 521 is connected to the telescopic rod 522, and the telescopic rod 522 is provided with a plurality of connection holes, and the first support rod 42 is fixed to the telescopic rod 522 by passing bolts through the connection holes of the telescopic rod 522, which is conducive to conveniently fixing the support mechanism, and the fixing is reliable, the structure is simple, and the adjustment is convenient.

[0033] like Figures 1 to 5 As shown, a limiting plate 511 is fixed at the bottom of the center tube 51, and a plurality of second driving motors 512 are installed at the bottom of the limiting plate 511. A screw rod 513 is transmission-connected to the output shaft of the second driving motor 512, and the number of the screw rods 513 is the same as the number of the supporting feet; the screw rods 513 are all connected to a sliding plate 514, and a plurality of first connecting seats 515 matching the number of supporting feet are installed on the sliding plate 514, and a connecting rod 516 is hinged on the first connecting seat 515, and a second connecting seat 5211 is fixed on the third support rod 521, one end of the connecting rod 516 is hinged to the first connecting seat 515, and the other end of the connecting rod 516 is hinged to the second connecting seat 5211.

[0034] The lead screw 513 is driven to rotate by a driving motor, and the lead screw 513 converts the rotary motion into linear motion, driving the sliding plate 514 on the lead screw 513 to automatically adjust upward or downward. When the sliding plate 514 moves downward, the angle between the first support rod 42 on the support foot and the center tube 51 becomes larger, which is conducive to automatically adjusting the support amplitude and support height of the support foot, making support more convenient and achieving better support effect.

[0035] like Figures 1 to 5 As shown, a caster 63 assembly is hinged on one side of the grounding member, and a limiting block 61 is symmetrically arranged on the grounding member. The caster 63 assembly includes a hinge plate 62 and a caster 63. The hinge plate 62 is connected to one side of the grounding member. Both ends of the hinge plate 62 are provided with a first sliding groove. The first sliding groove includes a first spring 621 and a limiting rod 622. The first spring 621 is fixed on a side of the first sliding groove away from the grounding member. The first spring 621 is fixedly connected to the limiting rod 622. One end of the limiting rod 622 has a limiting portion. The limiting block 61 has a limiting groove, and the limiting portion is limitedly connected in the limiting groove.

[0036] When the laser surveying instrument 25 is needed, the caster 63 can be rotated and folded through the hinged plate 62. When the caster 63 is folded, the limit rod 622 in the first sliding groove can be pushed in the direction of the first spring 621 until the caster 63 is rotated to the point where the limit rod 622 is located directly above the limit groove of the limit block 61. The limit rod 622 is then released, and the first spring 621 rebounds to clamp the limit rod 622 into the limit groove of the limit block 61, thereby clamping the hinged plate 62 on the grounding piece, which is conducive to a secure connection, convenient use, and greater practicality.

[0037] like Figures 1 to 5 As shown, an observation pointer 71 and a level 72 are also installed on the observation box 32 , the observation pointer 71 is aligned with the center of the level 72 , and handles 73 are installed on both sides of the observation box 32 .

[0038] By adding a level 72, the user can observe in real time whether the laser surveying instrument 25 is in a state perpendicular to the ground. The setting of the observation pointer 71 is conducive to improving the observation effect and making observation more convenient. By setting a handle 73 on the observation box 32, it is convenient for the user to put his hand on the handle 73 during adjustment, which is convenient for adjustment and more comfortable.
