Steel structure buildings are gradually being promoted and applied due to their many advantages such as fast construction speed, disassembly and recycling. During construction, steel structure buildings need to be scanned in order to quickly establish a complex three-dimensional visual model, so as to facilitate subsequent inspection and comparison of the finished steel structure with the design drawings.

[0003] The existing Chinese patent with application number: 202121357694.6 discloses a three-dimensional laser scanner for steel structure installation, including a main body, an adjustment mechanism, a scanner, a handle, an indicator light, a scanning mirror, a rotating axis support foot mirror cover and a fixing mechanism, characterized in that: a rotating axis is provided on the outer surface of the main body, a supporting foot is provided on one side of the rotating axis, a fixing mechanism is provided on one side of the supporting foot, an adjustment mechanism is provided on the upper outer surface of the main body, and a scanner is provided on the upper outer surface of the adjustment mechanism.

[0004] Although the above technology has a certain degree of protection effect on the scanning mirror lens when in use, since it does not have a lifting component, the scanning radius of the scanning equipment is restricted when scanning the steel structure, which in turn affects the scanning efficiency; therefore, in order to solve the above technical problems, we propose a digital detection device for steel structures based on three-dimensional scanning.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

This is the prior art and will not be described in detail in this scheme. The upper end of the innermost lifting sleeve 3 is connected with a scanner 1 through a quick-release assembly, and the lower end of the outermost lifting sleeve 3 is connected with a base 2. An air cavity 5 is arranged inside the base 2 and a winding drum 6 is installed in the air cavity 5.

A synchronous disk 8 is arranged on one side of the outer ring surface of the base 2, and locking components are arranged on both sides of the synchronous disk 8.

[0028] Example 2

[0029] Reference Figure 1-7 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0030] The quick-release assembly includes a mounting plate 10, a connecting plate 11, bolts 12 and a locking plate 13. The mounting plate 10 is fixed to the upper end of the innermost lifting sleeve 3. The locking plate 13 is mounted on both sides of the mounting plate 10 by means of bolts 12. Matching slots are provided on both sides of the connecting plate 11 corresponding to the locking plates 13. The scanner 1 is mounted on the upper surface of the connecting plate 11. The quick-release assembly is provided so that when a person installs the scanner 1, the locking plate 13 is moved toward the inside of the mounting plate 10 by means of the bolts 12. At this time, the connecting plate 11 can be directly placed inside the mounting plate 10. Then, one side of the locking plate 13 is moved into the slot of the connecting plate 11 by means of the bolts 12. At this time, the locking plate 13 is engaged with the scanner 1. The connecting plate 11 and the mounting plate 10 are in a fixed connection state, that is, the scanner 1 is installed; the locking component includes a plurality of limit holes 14 and two latches 15, the limit holes 14 are distributed in a circle with the axis of the synchronous disk 8 as the center, and the two latches 15 are inserted on both sides of the synchronous disk 8 and connected to adjacent limit holes 14. The setting of the locking component is convenient for limiting the synchronous disk 8, that is, preventing the synchronous disk 8 from rotating, so as to facilitate controlling the position of the winding reel 6, that is, controlling the length of the traction rope 7 released; a rotating block 4 is fixed to the middle of the side of the synchronous disk 8 away from the base 2, and the cross-section of the rotating block 4 is hexagonal. The setting of the rotating block 4 is convenient for personnel to rotate the synchronous disk 8 through an external wrench.

[0031] A pressure gauge 16 is installed on one side of the upper surface of the base 2. There are two air nozzles 9, which are a US nozzle and a French nozzle respectively. The setting of the US nozzle and the French nozzle is convenient for adapting to external pumping facilities; a guide ring 17 is installed inside the upper body wall of the base 2 corresponding to the lifting sleeve 3 and the air cavity 5, and the rope body of the traction rope 7 is passed through the middle of the guide ring 17. The setting of the guide ring 17 is convenient for reducing the wear between the traction rope 7 and the lifting sleeve 3. Support feet 18 are installed at the four corners of the outer ring surface of the base 2 through threads, and an adjusting cylinder 19 is installed through threads on the end of the supporting foot 18 away from the base 2. A limiting hole is provided on the end of the adjusting cylinder 19 away from the supporting foot 18. The setting of the adjusting cylinder 19 is convenient for extending the contact length between the device and the ground, thereby making the base 2 more stable when in use.

[0032] Principle and advantages of use: During the use of the utility model, when it is necessary to perform three-dimensional scanning on steel structure components or steel structure buildings, the device is installed on the ground through the base 2, and the scanner 1 is installed on the upper end of the lifting sleeve 3 through a quick-release assembly. At this time, the steel structure components or steel structure buildings can be scanned through the scanner 1, so as to obtain data such as the shape and position of the steel structure components or steel structure buildings, which is convenient for subsequent personnel to compare the actual objects with the drawings; and in the above process, if the area to be scanned is too large or too high, gas is pumped into the air cavity 5 of the base 2 through an external manual air pump or an air pump and other facilities, and as the gas inside the air cavity 5 is pumped into, the gas pushes several lifting sleeves 3 to move upward, thereby achieving the effect of lifting and lowering the scanner 1.

[0033] At the same time, in the above process, the personnel first remove the latch 15, and the synchronization disk 8 can rotate freely. That is, when the lifting sleeve 3 moves upward, it can drive the traction rope 7 to move upward, that is, the traction rope 7 drives the winding drum 6 to rotate, so that the traction rope 7 is released from the winding drum 6. Further, when the position of the scanner 1 is determined, the synchronization disk 8 can be fixedly connected with the base 2 through the latch 15. That is, at this time, under the action of a number of strong magnetic columns 20, the winding drum 6 cannot rotate, that is, the traction rope 7 cannot continue to be released. Then, as the gas is continuously pumped in, the air pressure inside the air cavity 5 increases accordingly. Then, as the air pressure inside the air cavity 5 increases, the amplitude of the up and down shaking of the lifting sleeve 3 is gradually reduced, thereby avoiding the phenomenon that the lifting sleeve 3 shakes up and down and causes the scanner 1 to shake itself during scanning.

[0034] In summary, in the present solution, by pumping air into the base 2 through the air nozzle 9, the gas can be used to push the lifting sleeve 3 to drive the scanner 1 to move up and down, thereby achieving the effect of conveniently adjusting the height of the scanner 1, and the scanner 1 with a higher height can make the scanning radius larger, thereby improving the efficiency of the scanner 1 in scanning the steel structure, and through the setting of the traction rope 7, the height of the lifting sleeve 3 can be constrained, thereby making the air pressure inside the base 2 and the lifting sleeve 3 higher, that is, the lifting sleeve 3 and the scanner 1 will not easily shake up and down, thereby improving the stability of the scanner 1 during scanning, and through the setting of a number of strong magnetic suction columns 20, there is no direct contact between the winding reel 6 and the synchronization disk 8, which can avoid the phenomenon of gas leakage from the base 2.

[0035] It should be further explained that the setting of the quick-release assembly allows personnel to quickly install and disassemble the scanner 1; the setting of the locking component is convenient for limiting the synchronization disk 8, that is, preventing the synchronization disk 8 from rotating, so as to facilitate controlling the position of the winding reel 6, that is, controlling the length of the traction rope 7 released; the setting of the rotating block 4 is convenient for personnel to rotate the synchronization disk 8 through an external wrench; the setting of the American nozzle and the French nozzle is convenient for adapting to external pumping facilities, and the setting of the barometer 16 is convenient for personnel to control the internal air pressure value of the air cavity 5; the setting of the guide ring 17 is convenient for reducing the wear between the traction rope 7 and the lifting sleeve 3, and the setting of the support foot 18 and the adjustment cylinder 19 is convenient for extending the contact length of the device with the ground, so that the base 2 is more stable when in use.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
