Description

Technical Field

[0001] The utility model relates to the technical field of cultural relics and historical sites, in particular to a telescopic frame for collecting data on cultural relics and historical sites at heights. Background Art

[0002] High-altitude cultural relics refer to historical sites or relics located at higher positions, such as the tops of towers, murals, statues, etc. of ancient buildings. Due to their special location, the daily maintenance and research of such cultural relics become very difficult. The murals of some ancient monuments are exposed to the influence of natural factors such as weathering and erosion. In order to prevent the further loss of precious historical information, it is particularly important to record and digitally archive these high-altitude murals in detail. Through high-precision 3D scanning, photogrammetry and other technologies, digital models can be established for research, education and possible restoration work in the future.

[0003] Currently, there are some obvious challenges when collecting data on cultural relics at heights. The first is how to reach the location of the cultural relics safely and efficiently, the second is how to obtain high-quality data without touching the cultural relics, and the last is how to handle data collection work in complex environments. When working at heights, how to ensure the stability of the equipment has become a key issue. Although traditional tripods can provide certain support, when used at higher positions, they often encounter problems with insufficient stability, especially in windy conditions. The equipment is prone to shaking or even falling, which affects the scanning effect. At the same time, the scanning frame with a single structure is not conducive to scanning large areas, large amplitudes, and large ranges. Utility Model Content

The center of the semicircular plate 202 is connected to the plate body of the vertical plate 201 through the central axis 2011 at the lower side. A semicircular groove 2021 is provided on the body of the semicircular plate 202. The damping shaft 203 is threadedly connected to the lower half of the body of the vertical plate 201. A second handle 204 is provided at the center of the damping shaft 203. The center of the circle 203 is provided with a limiting pressing piece fixedly connected to the rotating shaft of the second handle 204. When in use, the first chassis 301 sleeved on the first vertical tube 101 is moved up and down, so that after the legs 304 are opened, the second chassis 302 will not move downward again under the limiting effect of the legs 304 around the umbrella ribs 305, thereby achieving preliminary stable placement. By rotating the fastening bolts on the hoop and then stretching the second vertical tube 103, the third vertical tube 105 and the fourth vertical tube 107, the height of the device can be reasonably set. When the vertical angle of the scan needs to be adjusted, it is only necessary to loosen the pressing piece on the second handle 204 by rotating the second handle 204, and then rotate the semicircle ring to the ideal angle, and then rotate the second handle 20 in the opposite direction. 4. The compression piece of the second handle 204 re-tightens the semicircular ring to fix the upper and lower angles. The pan-tilt head 110 can be electronically controlled by functions such as Bluetooth. The shooting equipment installed on the pan-tilt head 110 can be adjusted. When the horizontal scanning angle needs to be adjusted, the fastening bolt on the third hoop 106 can be loosened, and then the third vertical tube 105 and the third vertical tube 105 are rotated relative to each other to adjust the horizontal angle of the pan-tilt head 110. The first transverse tube 113 and the second transverse tube 115 are installed in a sleeve manner. When the reel 109 pulls the pan-tilt head 110 back, the second transverse tube 115 will retract into the first transverse tube 113. Under the action of the lever principle, the rope of the reel 109 will be symmetrical with the limit block 108. , and the balance of the lever is re-formed. By setting up the adjustment mechanism 2, the vertical plate 201 installed on the semicircular ring can rotate around the central axis 2011 with a certain arc, which is reflected in the sleeve 112 that it can swing up and down at one end, and then the pan-tilt head 110 installed at the end of the second horizontal tube 115 can adjust the up and down angles, and the pan-tilt head 110 can be optionally electrically controlled to move, so as to scan the details of the ancient building in the vertical up and down directions. Combined with the third hoop 106, the third vertical tube 105 and the fourth vertical tube 107 can be rotated between them, which is reflected in the pan-tilt head 110 that the horizontal and horizontal rotation of the pan-tilt head 110 can be adjusted to realize left and right scanning. The combination of the two can perform scanning operations on ancient buildings at a fairly wide angle.

A limiting rod movably inserted into the limiting hole of the reel 109 is inserted through the first transverse tube 113. The rope of the reel 109 passes through the circular hole of the limiting block 108 and is connected to the side connecting plate 111. When the reel 109 pulls the pan-tilt head 110 back, the second transverse tube 115 will retract into the first transverse tube 113. Under the action of the lever principle, the rope of the reel 109 will be symmetrical with the limiting block 108, and the balance of the lever will be restored.

[0038] Specifically, the working process or working principle of the telescopic stand for collecting data on cultural relics and historical sites at high altitudes is as follows: when in use, the first chassis 301 sleeved on the first vertical tube 101 is moved up and down, so that after the legs 304 are opened, the second chassis 302 will not move downward any further due to the limiting effect of the legs 304 on all sides of the ribs 305, thereby achieving initial stable placement. By rotating the fastening bolts on the hoop and then stretching the second vertical tube 103, the third vertical tube 105 and the fourth vertical tube 107, the height of the device can be reasonably set. When it is necessary to adjust the vertical angle of the scan, it is only necessary to rotate the second handle 204 to loosen the pressing piece on the second handle 204, and then rotate the semicircular ring to the ideal angle, and then rotate the second handle 204 in the opposite direction.
