[0002] With the development of modern buildings towards high-rise, large-span and complex structural forms, as well as the increase in the service time of existing buildings, building structures are facing various complex stress environments and potential safety hazards. Accurately measuring the displacement of building structures is an important means to evaluate the structural safety and health status:

[0003] For some complex building construction schemes, such as the overall lifting of large structures and the construction of transfer floors, etc., this device can verify the feasibility and safety of the construction scheme by measuring the displacement changes of the structure during the construction process. If the measurement results show that the structural displacement exceeds the expected range, it is necessary to adjust and optimize the construction scheme to ensure the safety and stability of the structure during the construction process:

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1-7As shown in the figure, the utility model is a high-precision building structure displacement measuring device, including a chassis 1. A protective cover 101 is fixedly connected to the outer wall of the top of the chassis 1. A number of circular grooves 102 are formed in the inner wall of the protective cover 101. A level 103 is fixedly connected to the outer wall of the top of the protective cover 101. The level 103 is used to detect whether the device is placed flat, so as to avoid uneven placement of the device. An adjusting mechanism 2 is arranged on the outer wall of the chassis 1. The adjusting mechanism 2 includes a number of mounting plates 201. The outer walls of the number of mounting plates 201 are fixedly connected to the outer wall of the chassis 1. A circular hole 202 is formed in the inner wall of the mounting plate 201. A sliding rod 203 is slidably connected to the inner wall of the circular hole 202. When the sliding rod 203 slides in the circular hole 202, the circular hole 202 will maintain horizontal movement to prevent the sliding rod 203 from shaking. A circular ring 204 is fixedly connected to the outer wall of the sliding rod 203 close to the protective cover 101. A number of rotating shafts 205 are fixedly connected to the inner wall of the circular ring 204. A connecting rod 206 is rotatably connected to the outer wall of the rotating shaft 205. When the circular ring 204 moves, it will drive the sliding rod 203 to slide in the circular hole 202. At the same time, the circular ring 204 will drive the rotating shaft 205 to move. When the rotating shaft 205 moves, it will drive the connecting rod 206 to move in an arc, realizing the kinetic energy conduction between parts. A joint shaft 207 is rotatably connected to the inner wall of the connecting rod 206. A fixing rod 208 is fixedly connected to the outer wall of the joint shaft 207 close to the protective cover 101. The outer wall of the fixing rod 208 is slidably connected to the inner wall of the circular groove 102. A spring 209 is sleeved on the outer wall of the fixing rod 208. When the connecting rod 206 moves, it will drive the joint shaft 207 to move, and then the joint shaft 207 will drive the fixing rod 208 to slide in the circular groove 102. When the fixing rod 208 slides, it will compress the spring 209. When the spring 209 is compressed on the fixing rod 208, the spring 209 will not be misaligned, ensuring the normal use of the spring 209. A roller 210 is rotatably connected to the inner wall of the protective cover 101. A disc 211 is fixedly connected to the outer wall of the roller 210 close to the protective cover 101. A card slot 212 is formed in the inner wall of the disc 211. When the fixing rod 208 moves, it will be stuck in the card slot 212, making the disc 211 unable to rotate, preventing the disc 211 from rotating due to external force. A fixing plate 213 is fixedly connected to the outer wall of the roller 210 far from the protective cover 101. A number of fixing frames 214 are fixedly connected to the outer wall of the top of the fixing plate 213. A rotating rod 215 is rotatably connected to the inner wall of the fixing frame 214. When the roller 210 rotates, it will drive the fixing plate 213 to rotate, and then the fixing plate 213 will drive the fixing frame 214 to rotate. At the same time, the rotating rod 215 will rotate with the fixing frame 214, realizing the kinetic energy transmission between parts. A support frame 216 is fixedly connected to the outer wall of the top of the fixing plate 213. A worm 217 is rotatably connected to the inner wall of the support frame 216. A worm gear 218 is fixedly connected to the outer wall of the rotating rod 215 close to the worm 217. The outer wall of the worm gear 218 is meshed with the outer wall of the worm 217. A support plate 219 is fixedly connected to the outer wall of the rotating rod 215.When the worm 217 rotates, it drives the worm wheel 218 to rotate. At the same time, the rotating rod 215 rotates along with the worm wheel 218. When the rotating rod 215 rotates, it drives the support plate 219 to rotate, facilitating the operator to control the measurement angle. A laser displacement sensor 220 is fixedly connected to the outer wall of the top of the worm wheel 218. A support mechanism 3 is arranged on the inner wall of the chassis 1. The model of the laser displacement sensor 220 is Omron ZS-L. This series of sensors uses 2D CMOS technology and has a high measurement resolution of up to 0.25μm, enabling sub-micron level precision measurement. The displacement of building structures is usually relatively small, especially in safety monitoring, where extremely subtle changes need to be accurately captured. The high precision of this sensor can meet the strict requirements for the precision of building structure displacement measurement.

[0032] The support mechanism 3 includes a threaded rod 301. The outer wall of the threaded rod 301 is rotatably connected to the inner wall of the chassis 1. A gear 302 is fixedly connected to the outer wall of the threaded rod 301. A fixed block 303 is fixedly connected to the outer wall of the bottom of the chassis 1. When the rolling rod 304 rotates in the fixed block 303, the rolling rod 304 will not shake, making the rolling rod 304 rotate more smoothly. The inner wall of the fixed block 303 is rotatably connected to a rolling rod 304. A crown gear 305 is fixedly connected to the outer wall of the rolling rod 304 close to the gear 302. The outer wall of the crown gear 305 is meshed with the outer wall of the gear 302. When the rolling rod 304 rotates, it drives the crown gear 305 to rotate. At the same time, the crown gear 305 drives the gear 302 to rotate, and then the threaded rod 301 rotates along with the gear 302, realizing the kinetic energy transmission process between the parts.

[0033] A number of joint shafts two 306 are fixedly connected to the outer wall of the bottom of the chassis 1. A threaded block 307 is threadedly connected to the outer wall of the threaded rod 301. A support block 308 is fixedly connected to the outer wall of the threaded block 307. A fixed rod two 309 is fixedly connected to the inner wall of the support block 308. When the threaded rod 301 rotates, it drives the threaded block 307 to move. Then the threaded block 307 drives the support block 308 to move. At the same time, the fixed rod two 309 moves along with the support block 308, realizing that when one part moves, other parts will also move accordingly. A number of connecting rods 310 are rotatably connected to the outer wall of the fixed rod two 309. A support leg 311 is rotatably connected to the outer wall of the joint shaft two 306. A chute 312 is opened on the inner wall of the support leg 311. A transmission rod 313 is fixedly connected to the inner wall of the chute 312. The outer wall of the transmission rod 313 is rotatably connected to the inner wall of the connecting rod 310. When the fixed rod two 309 moves, it drives the connecting rod 310 to move in an arc. At the same time, the connecting rod 310 drives the transmission rod 313. When the transmission rod 313 moves, it drives the support leg 311 to move, facilitating the operator to place the equipment on the ground.

[0034] A specific application of this embodiment is:

[0035] When the staff needs to use the device, first place the device on the ground. When preparing to place it, first rotate the rolling rod 304. When the rolling rod 304 rotates, it will drive the crown gear 305 to rotate. When the crown gear 305 rotates, it will drive the gear 302 to rotate. At the same time, the threaded rod 301 will rotate with the gear 302. When the threaded rod 301 rotates, it will drive the threaded block 307 to move. Then when the threaded block 307 moves, it will drive the support block 308 to move. At the same time, the fixed rod two 309 will move with the support block 308. When the fixed rod two 309 moves, it will drive the connecting rod 310 to move in an arc. At the same time, the connecting rod 310 will drive the transmission rod 313 to move. When the transmission rod 313 moves, it will drive the support leg 311 to rotate on the joint axis two 306. When the support leg 311 rotates to an appropriate angle, stop rotating the rolling rod 304. Then place the device on the ground through the support leg 311, which is convenient for the operator to place the device. When the personnel use the device, they can first check whether the level 103 is flat. When the level 103 is flat, start the laser displacement sensor 220. Then the laser displacement sensor 220 will check the building structure. At the same time, the device can be adjusted according to the orientation of the building structure. When adjusting the device, first move the ring 204 upward. When the ring 204 moves, it will drive the sliding rod 203 to slide in the round hole 202. When the ring 204 moves, it will drive the rotating shaft 205 to move. Then the rotating shaft 205 drives the connecting rod 206 to move in an arc. When the connecting rod 206 moves, it will drive the joint axis 207 to move. At the same time, the fixed rod 208 will move with the joint axis 207. When the fixed rod 208 moves, it will squeeze the spring 209. At the same time, the fixed rod 208 will move out of the card slot 212. After moving out, the fixing plate 213 can be rotated. When the fixing plate 213 rotates, it will drive the roller 210 to rotate. At the same time, the disc 211 will rotate with the roller 210. Then when the fixing plate 213 rotates, it will drive the fixing frame 214 to rotate. At the same time, the rotating rod 215 rotates with the fixing frame 214. When the rotating rod 215 rotates, it will drive the support plate 219 to rotate. Then the support plate 219 drives the laser displacement sensor 220 to rotate, which is convenient for the operator to adjust the orientation detected by the laser displacement sensor 220. After the adjustment is completed, release the ring 204. After the ring 204 is released, the spring 209 will squeeze the fixed rod 208, so that the fixed rod 208 is reinserted into the card slot 212. At the same time, other parts will also return to their original positions. After the fixed rod 208 is inserted into the card slot 212, the disc 211 cannot rotate. After the disc 211 cannot rotate, the roller 210 cannot rotate either. At the same time, the laser displacement sensor 220 cannot rotate due to the fixation of other parts. Then the worm 217 can be rotated. When the worm 217 rotates, it will drive the worm gear 218 to rotate. Then the rotating rod 215 will rotate with the worm gear 218. When the rotating rod 215 rotates, it will drive the support plate 219 to rotate. At the same time, the laser displacement sensor 220 will rotate with the support plate 219, which is convenient for the operator to adjust the detection angle of the laser displacement sensor 220.
