Usually, it is manifested as uniform or non-uniform settlement of the building, or some cracks, tilting, twisting, displacement phenomena, when the deformation value exceeds the allowable value of the building design, it will cause a certain degree of damage to the building.

[0049] In this embodiment, the mounting assembly 1 further includes a fixing cone 12. The fixing cone 12 is slidably inserted into both sides of the base 11. A screw 14 is rotatably mounted inside the vertical frame 13 via a bearing. The sliding frame 15 is threaded onto the screw 14. A connecting shaft 17 is rotatably mounted on the front of the connecting plate 16, located on top of the threading tube 34. A scale ring 18 is provided on the outer ring of the connecting shaft 17. The scale ring 18 is fixed on the connecting plate 16. A buckle frame 110 is fixed on the surface of the connecting shaft 17, and the outer end of the buckle frame 110 is slidably sleeved on the surface of the scale ring 18. The moving assembly 2 further includes a plug 217. A plug 217 is fixed on one end of the rotating shaft seat 24 facing the connecting shaft 17. A slot 19 is provided on the outer surface of the connecting shaft 17. The plug 217 is slidably inserted into the slot 19. A third gear 220 is fixedly sleeved on the rear end of the rotating shaft seat 24 at the plug 217. A second tooth is meshed on one side of the third gear 220. The wheel 219, the mounting base 21 corresponding to the rear end of the second gear 219 is fixed with a drive motor 218, and the output end of the drive motor 218 is fixedly connected to the second gear 219. The position of the sliding frame 15 and the connecting plate 16 is adjusted by rotating the screw 14 to keep the two sets of mounting components 1 and the laser emitter 6 at the same height, so as to avoid errors caused by different heights. When each set of moving components 2 is connected to the mounting component 1, the insert 217 of the rotating shaft seat 24 is inserted into the slot 19, and then the drive motor 218 drives the second gear 219 to rotate and mesh with the third gear 220. While adjusting the angle of the laser emitter 6 and aligning it with the receiving target plate 5, the connecting shaft 17 and the buckle frame 110 rotate synchronously due to the engagement of the insert 217 with the slot 19, and move along the surface of the scale ring 18. The scale ring 18 has angle markings, so the angle information of the laser emitted by the laser emitter 6 can be known after adjustment. The base 11 is fixed to the ground by the fixing cone 12 to maintain the stability of the device.

[0050] The rear end of the mounting base 21 is rotatably connected to the side of the connecting plate 16 through a rotating shaft, and the other side of the rear end of the mounting base 21 is fixedly connected to a clamping frame 26. The upper end of the clamping frame 26 is hollow, and the telescopic measuring rod 25 is inserted into the clamping frame 26 in parallel. The outer end of the rotating shaft of the telescopic measuring rod 25 is fixedly connected to a first bevel gear 28, and the side of the first bevel gear 28 is connected to a second bevel gear 29. The outer wall of the mounting base 21 is fixedly connected to a bearing frame 210 corresponding to the position of the second bevel gear 29, and the second bevel gear 29 is rotatably connected to the bearing frame 210. The rear end of the bearing frame 210 is rotatably connected to a first gear 211, and the first gear 211 is fixedly connected to the second bevel gear 29. The top of the first gear 211 is connected to a toothed plate 212, and the other end of the toothed plate 212 is fixedly connected to a connecting frame 213. The connecting frame 213 penetrates into the hollow slot 214. The bottom of the traction rope 31 is fixedly connected to a fixed block 35 corresponding to two groups of mounting bases 21. The two sides of the fixed block 35 are provided with clamping plates 216 in the hollow slot 214. The inner wall of the hollow slot 214 is fixedly connected to a double-way electric push rod 215 at the two ends of the clamping plates 216. The two elongated ends of the double-way electric push rod 215 are fixedly connected to the clamping plates 216. The connecting frame 213 is fixedly connected to one side of the clamping plate 216. In the initial state, the two groups of moving assemblies 2 are not locked and connected to the traction rope 31, that is, the clamping plates 216 do not clamp the fixed block 35, and the mounting base 21 is clamped on the threading drum 34. At this time, the telescopic measuring rod 25 is transversely arranged, and the laser is emitted to the high-rise building 4. When displacement measurement is needed, the state of one group remains unchanged, and the other group of moving assemblies 2 clamps the fixed block 35 through the double-way electric push rod 215 after the laser emitted by the laser emitter 6 is received on the receiving target plate 5. At this time, the toothed plate 212 is moved through the connection of the connecting frame 213. The toothed plate 212 is engaged with the first gear 211 to make the first gear 211 and the second bevel gear 29 rotate synchronously, and the telescopic measuring rod 25 rotates vertically. Then, under the action of the traction rope 31, it moves towards the other group of moving assemblies 2 and the laser emitter 6, and after passing through the guide seat 32, the moving assembly 2 rotates on a straight line with the other group. Then, the other group of transversely arranged telescopic measuring rods 25 can be inserted into the clamping frame 26. The transverse distance between the two groups of moving assemblies 2 and the laser emitter 6 can be measured, and the coordinate information can be obtained according to the angles of the two groups. Through the comparison of the two points, the offset direction and angle of the high-rise building 4 can be obtained.

[0051] The traction assembly 3 also includes an electric winding seat 36 in this embodiment. The connecting plate 16 is fixed with the electric winding seat 36 at the bottom of the threading drum 34, and both ends of the traction rope 31 are wound on the winding shaft of the electric winding seat 36. The bottom of the guide seat 32 is fixed with a vertical column 33, and the vertical column 33 is vertically inserted into the ground. The guide seat 32 and the vertical column 33 are fixed at a position between the two groups of laser emitters 6, corresponding to the right-angled side of the high-rise building 4. One group of the two groups of vertically arranged moving assemblies 2 is kept stationary, and the mounting seat 21 of the other group of moving assemblies 2 is locked with the traction rope 31. The electric winding seat 36 on the two connecting plates 16 is driven by the motor to wind and unwind one by one, driving the locked mounting seat 21 to move in the same direction as the traction rope 31. When passing through the guide seat 32, the mounting seat 21 can smoothly pass through the gap at the upper end of the guide seat 32 because the position of the bottom of the mounting seat 21 connected with the traction rope 31, so there is no movement interference. At the same time, the hollow slot 214 at the bottom of the mounting seat 21 can facilitate the mounting seat 21 to rotate around the guide seat 32 to change direction to the other side, and be flush with the other group of moving assemblies 2 and the laser emitters 6, so as to measure two points of the high-rise building 4 on the same side.

[0052] For the high-rise building 4 that needs to be measured for displacement, there are four right-angled sides in total. When measuring, two groups of moving assemblies 2, mounting assemblies 1 and laser emitters 6 can be arranged on the four right-angled sides at the same time. The laser emitters 6 correspond to two vertical surfaces of the high-rise building 4. Then, the receiving target plate 5 is arranged at the top of the high-rise building corresponding to the position of the laser emitter 6. The position of the sliding frame 15 and the connecting plate 16 is adjusted by rotating the screw rod 14 to keep the two groups of mounting assemblies 1 and the laser emitters 6 at the same height, avoiding errors caused by different heights. When each group of moving assemblies 2 meets the mounting assembly 1, the plug 217 of the rotating shaft seat 24 is inserted into the insertion slot 19, and then the motor 218 drives the second gear 219 to rotate and engage with the third gear 220. The angle of the laser emitter 6 can be adjusted while aligning with the receiving target plate 5. Because of the clamping of the plug 217 and the insertion slot 19, the connecting shaft 17 and the buckle frame 110 rotate synchronously, moving along the surface of the scale ring 18. The scale ring 18 has angle marks, so the angle information of the laser emitted by the laser emitter 6 can be obtained after adjustment. The base 11 is fixed to the ground by the fixing cone 12 to keep the stability of the device, so that the receiving target plate 5 can receive the laser. Figure 13As shown, initially, only one laser point on the target plate 5 is received, which is called the first laser point 51. In the initial state, the two groups of moving assemblies 2 are not locked with the traction rope 31, that is, the clamping plates 216 do not clamp the fixed blocks 35, and the mounting seats 21 are clamped on the threading drums 34. At this time, the telescopic measuring rods 25 are transversely arranged, and the laser emitted by the high-rise building 4 is received. When displacement measurement is needed, the state of one group remains unchanged, and the other group of moving assemblies 2 is clamped with the fixed blocks 35 by the double-way electric push rod 215 after the laser emitted by the laser emitter 6 is received on the receiving target plate 5. At this time, the connection of the connecting frame 213 drives the gear plate 212 to move, the gear plate 212 is engaged with the first gear 211, the first gear 211 and the second bevel gear 29 are synchronously rotated, the telescopic measuring rod 25 is rotated to be vertical, and then is moved towards the other group of moving assemblies 2 and the laser emitter 6 under the drive of the traction rope 31.

10. A method for measuring the drift displacement of a super high-rise building, employing a system for measuring the drift displacement of a super high-rise building as described in any one of claims 1 to 9, characterized in that: The measurement method includes the following steps: (1) Two sets of moving components, installation components and laser emitters are arranged on the four right-angled sides of the super high-rise building. The laser emitters correspond to the two vertical surfaces of the high-rise building. Then, a receiving target plate is arranged at the top of the high-rise building corresponding to the position of the laser emitter. (2) Adjust the installation height of the two sets of vertically corresponding laser emitters by installing the components, and then adjust the angle of the laser emitters by moving the components so that the laser emitted by them is received by the receiving target plate and kept in the middle position of the receiving target plate. (3) When displacement needs to be measured, select one side of the moving component to move under the drive of the traction component, and bring the two sets of moving components and laser emitters together on the same side of the high-rise building. At this time, the receiving target plate will receive the laser signals emitted by the two sets of laser emitters. (4) Compare the two laser signals on the receiving target plate, i.e. the deviation information of the two surfaces of the high-rise building. If the two laser points are on the same plane, it means that there is no displacement change on both sides of the right angle of the high-rise building. If the two laser points are not on the same plane, it means that there is displacement and angle change on both sides of the right angle of the high-rise building. (5) Based on the information on the left side of the two laser points on the receiving target plate, the offset direction and offset angle are obtained. The laser emitters around the four right-angled sides of the high-rise building are used to measure each face of the high-rise building in turn, and finally the offset direction is determined.
