Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping devices, and in particular to a laser measuring instrument for surveying and mapping highway projects. Background Art

[0002] As we all know, the laser measuring instrument used for highway engineering surveying is an advanced surveying tool. It can cooperate with highway engineering surveying personnel to carry out on-site auxiliary surveying and mapping operations, making it convenient to conduct surveying and mapping work on the corresponding areas of highway projects.

[0003] After searching, the Chinese patent publication number CN220398565U discloses a laser surveying instrument that is easy to adjust. It is roughly described as including a laser surveying instrument, a laser projector, a tripod, a top seat, and a fitting seat. The outer side of the laser surveying instrument is provided with a connecting mechanism that can quickly and conveniently connect the laser surveying instrument to the fitting seat of the tripod and an adjusting mechanism that can conveniently adjust the laser projection angle of the laser projector. When in use, the rotating shaft is driven by holding the handle, and the ball rotates in the rotating groove to adjust the angle of the laser projector. Through the fitting contact between the damping groove and the damping edge, resistance can be generated during the rotation of the two, thereby preventing the rotating shaft from rotating too fast, effectively improving the accuracy of the angle adjustment of the laser projector, and the rotating shaft is adjusted by twisting the threaded rod under the action of the bearing to push the limit block to fit with the limit groove. The patent with Chinese patent publication number CN218258742U also discloses a surveying and mapping UAV, which is roughly described as comprising a surveying and mapping UAV body, an auxiliary mechanism is arranged on the top of the surveying and mapping UAV body, a USB interface is fixedly connected to the top of the surveying and mapping UAV body and on the front of the auxiliary mechanism, a supporting tripod is fixedly connected to the bottom of the surveying and mapping UAV body, a non-slip pad is fixedly connected to the bottom of the supporting tripod, the auxiliary mechanism comprises an auxiliary frame slidably connected to the top of the surveying and mapping UAV body, a lithium battery is slidably connected inside the auxiliary frame, mounting plates are fixedly connected on both sides of the auxiliary frame, a connecting plate is slidably connected inside the mounting plate, and an additional lithium battery is installed by using the auxiliary mechanism in the device, and when in use, the corresponding surveying and mapping operation is realized by flying the surveying and mapping UAV.

[0004] Although the above-mentioned existing technical solutions can achieve the purpose of surveying and mapping, the former laser surveying instrument, which is easy to adjust, requires more manual intervention in the process of surveying multiple surveying points, so the efficiency of surveying and mapping needs to be further improved. In addition, once the actual surveying and mapping process is blocked by the surface trend or surface buildings, the corresponding surveying and mapping is difficult to carry out, and the surveying and mapping range is greatly limited. For the latter surveying and mapping drone, its surveying and mapping needs to be kept in flight. Even if it has an additional lithium battery, the sustainability of surveying and mapping is still limited, especially for the surveying and mapping of highways with numerous and complicated surveying and mapping work, the practicality needs to be further enhanced.

[0040] To sum up, the working process of the laser measuring instrument for highway engineering surveying and mapping is as follows: when not in use, the remote control carrier in the laser measuring instrument for highway engineering surveying and mapping is in a retracted state as a whole. In this state, the telescopic rod of the electric telescopic rod 8 pushes the transmission frame 16 to form a relative displacement in the center frame 4. The displaced transmission frame 16 forms a traction effect relative to the transmission member 18, prompting the two sliding columns 17 to approach each other. Under the cooperation of the inner connecting spring 28 and the outer connecting spring 29, the two inner wing arms 19 are respectively rotated synchronously relative to the two outer wing arms 20 and the two inner wing arms 19 and the two outer wing arms 20 are brought together, so as to achieve the folding of the laser measuring instrument for highway engineering surveying and mapping. After folding, the overall size is greatly reduced, thereby achieving the effect of convenient carrying and storage. When in use, the electric telescopic rod 8 controls the transmission frame 16 to move toward the two inner wings in the aforementioned steps. The arms 19 and the two outer wing arms 20 are pushed in the opposite direction of the closing direction. Under the synchronous pushing action of the transmission frame 16 on the two transmission members 18, the two sliding columns 17 will be pushed to form a relative distance. Due to the traction action of the inner traction rope 26 and the outer traction rope 25, when the two sliding columns 17 move away from each other, the two inner wing arms 19 will form a relative rotation adjustment relative to the two outer wing arms 20, so as to ensure that the two inner wing arms 19 are respectively rotated and unfolded relative to the two outer wing arms 20, so as to achieve the four wheel rims 35 can be relatively separated, so as to form a stable support for the center frame 4. When it is necessary to travel on the surface, the rotation amplitude of the inner wing arm 19 and the outer wing arm 20 is controlled so that the traction ring 23 has not yet entered the corresponding reduced diameter area on the ring track 24. In this way, under the elastic pushing action of the maintaining spring, the wheel rim 35 remains in an upright state. At this time, the state is as shown in the attached figure. Figure 1 As shown, when flying is required, the electric telescopic rod 8 continues to work to form a relative push between the two sliding columns 17, so that the traction of the inner traction rope 26 and the outer traction rope 25 causes the rotation amplitude of the inner rotating frame and the outer rotating frame to be larger, until the traction ring 23 enters the corresponding reduced diameter area on the ring track 24. Under the traction effect of the corresponding reduced diameter area on the ring track 24 on the traction ring 23, a relative drive will be formed between the threaded rod 21 and the threaded sleeve 22 that are threadedly matched with each other, which will cause the threaded rod 21 to rotate relative to the threaded sleeve 22, prompting the wheel 35 to enter the horizontal state from the upright state, which is convenient for the laser measuring instrument for highway engineering surveying and mapping to enter the flying state.

[0041] Furthermore, the swing arm platform 1 is coordinated with the operation of the electric telescopic rod 8. Due to the transmission effect of the driving rack 9, the transmission gear ring 13, the synchronous frame 14, the connecting spring 15 and the transmission frame 16, when the electric telescopic rod 8 controls the folding of the two inner wing arms 19 and the two outer wing arms 20, the swing arm platform 1 also forms a lying posture relative to the center frame 4. When the electric telescopic rod 8 controls the laser measuring instrument for highway engineering surveying and mapping to enter the attached Figure 1In the state shown, under the push of the transmission connecting frame 16, the swing arm platform 1 is above the center frame 4 relative to the center frame 4, which is convenient for the camera 2 and the laser surveying instrument 3 to be in a relatively high position relative to the center frame 4 to facilitate the acquisition of surveying and mapping graphics. When the highway engineering surveying and mapping laser measuring instrument enters the flying state, under the push of the transmission connecting frame 16, the swing arm platform 1 is below the center frame 4 relative to the center frame 4, which is convenient for the camera 2 and the laser surveying instrument 3 to be in a relatively low position relative to the center frame 4 to facilitate the acquisition of surveying and mapping graphics. The limit range of the swing arm platform 1 is limited by the relative sliding limit between the limiting strip 11 and the limiting groove 12. Due to the connection spring 15 When the swing arm platform 1 enters the limited position, the transmission frame 16 can also form a linkage adjustment with the transmission member 18 to enrich the adjustable range of the remote control carrier. When entering the flight state, the variable frequency motor 32 drives the rotating member 33 to rotate. When the rotating member 33 is driven to a certain speed by the variable frequency motor 32, the rotating sliding rotor 36 can overcome the relative magnetic attraction between the permanent magnet 38 and the plug plate 40 under the action of centrifugal force, so that the sliding rotor 36 can slide out relative to the fixed rotor 34. When the centrifugal force borne by the rotating sliding rotor 36 increases again, the sliding rotor 36 can overcome the elastic pulling force of the flexible spring 37 and move outward relative to the fixed rotor 34, so that the sliding rotor 36 and the fixed rotor 34 can be moved outward. 4, when the magnetic block 39 is relatively close to the permanent magnet 38, under the action of the relative magnetic force between the magnetic block 39 and the permanent magnet 38 and the rotational centrifugal force of the sliding rotor 36, the position of the sliding rotor 36 and the fixed rotor 34 after sliding out relative to each other is stabilized, that is, when the centrifugal force borne by the sliding rotor 36 is greater than a certain range of values, the sliding rotor 36 will not slide back relative to the fixed rotor 34, and when the centrifugal force borne by the sliding rotor 36 is less than a certain range of values, the sliding rotor 36 will slide back relative to the fixed rotor 34 under the traction of the flexible spring 37, so as to facilitate the transition between the two modes of surface travel and flight travel. Automatic switching, during the movement of the remote control carrier, when it enters a suitable surveying and mapping coordinate point, it enters a parked state. If it is moving on the surface, it is not moving relative to the surface. If it is flying and cannot land, it adopts a suspended and stationary parking mode.
