Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall falling risk detection, and in particular to a curtain wall falling risk detection device based on vibration measurement. Background Art

[0002] Building curtain wall refers to the non-load-bearing exterior wall enclosure of a building, which is usually composed of panels (glass, metal plates, stone slabs, ceramic plates, etc.) and the supporting structure behind it (aluminum beams and columns, steel structures, glass ribs, etc.); during the use of building curtain walls, there is a risk of the curtain walls falling, which in turn poses a safety hazard to the city's environment.

[0003] Chinese patent announcement number CN118347678A discloses a curtain wall falling risk detection device based on vibration measurement, including a bracket, the bracket is composed of a central shell and adsorption covers evenly arranged around the circumference of the shell, and each adsorption cover is fixed to the shell through a support rod, and a vibration sensor is arranged in each adsorption cover, and an excitation hammer is arranged in the shell, including a detector, and each vibration sensor is connected to the detector through a data line. This application places the bracket on the curtain wall glass so that the shell and each adsorption cover are buckled on the curtain wall glass, and then starts the vacuum pump through the vacuum button set on the detector, so that the vacuum pump evacuates the shell, and the vacuum degree in the shell is transmitted to each adsorption cover through the through hole, so that the shell and each adsorption cover are adsorbed on the curtain wall glass through the internal vacuum, thereby completing the purpose of fixing the bracket on the curtain wall glass.

[0004] In the prior art, when inspecting a glass curtain wall, the inspection device is controlled to be close to the glass curtain wall through an adsorption structure. The above-mentioned related technology has the following defects: in order to be able to inspect different positions of the glass curtain wall, the vibration structure of the detection device will perform multiple inspections by continuously changing the knocking position.

During the rotation of one reciprocating wire shaft, the reciprocating wire shaft moves with the transmission tooth plate to drive the transmission tooth plate to move from the left end to the right end. When the main tooth plate moves downward to the point where it can drive multiple oscillation sleeves to sequentially perform oscillation detection on the glass curtain wall, multiple positions of the glass curtain wall are detected.

[0030] The following is combined with Figure 1-9 The present invention is described in further detail.

[0031] The embodiment of the present invention discloses a curtain wall fall risk detection device based on vibration measurement. Figure 1-9 As shown, it includes a test installation mainboard 1 and a suspension connection frame 2. The suspension connection frame 2 is installed together with an external suspension structure and an adsorption structure, and can be adsorbed together with a glass curtain wall for stable detection. The rear end of the suspension connection frame 2 is installed on the front of the test installation mainboard 1. A plurality of evenly distributed detection receivers 3 are installed through the front of the test installation mainboard 1. A plurality of evenly distributed detection heads 4 are installed on the bottom surface of each detection receiver 3. The detection head 4 penetrates the front of the test installation mainboard 1. An oscillation structure 5 is slidably sleeved on the outer surface of each detection head 4. The oscillation structure 5 detects the vibration generated by the detection head 4 to the glass curtain wall. The test installation mainboard 1 is slidably sleeved on the outer surface of the oscillation structure 5. A threaded reciprocating structure 6 is installed above one end of the oscillation structure 5 in front of the detection head 4. The threaded reciprocating structure 6 is rotatably connected to the adjacent detection receiver 3.

[0032] The oscillation structure 5 includes an oscillation sleeve 51 and an engaging plate 52. The oscillation sleeve 51 is slidably sleeved on one end of the engaging plate 52. The rear end of the oscillation sleeve 51 is located behind the rear end of the detection head 4. The upper annular surface of the oscillation sleeve 51 is open. The engaging plate 52 is located inside the opening of the oscillation sleeve 51. One end of the engaging plate 52 located inside the oscillation sleeve 51 is elastically connected to the oscillation sleeve 51. The oscillation sleeve 51 is slidably sleeved on the outer surface of the adjacent detection head 4. The test installation main board 1 is slidably sleeved on the outer surface of the oscillation sleeve 51. The engaging plate 52 is meshed with the threaded reciprocating structure 6. When the engaging plate 52 moves back and forth, the oscillation sleeve 51 is driven to reciprocate and vibrate against the glass curtain wall through the elastic connection.

[0033] A multi-rod frame 7 is arranged in front of the test installation main board 1, and the multi-rod frame 7 is elastically connected to the front of the test installation main board 1. The middle position of the multi-rod frame 7 is located in front of each detection receiver 3 and is a non-round rod structure. A clamping tooth plate 8 is arranged on the upper left of each threaded reciprocating structure 6.

[0034] The threaded reciprocating structure 6 includes a threaded reciprocating screw 61, a large gear 62 and a small gear 63. The rear end of the threaded reciprocating screw 61 is rotatably connected to the adjacent detection receiver 3. The engaging plate 52 is threadedly sleeved on the outer surface of the threaded reciprocating screw 61. The large gear 62 and the small gear 63 are coaxially fixed on the outer surface of the threaded reciprocating screw 61, and the large gear 62 is located behind the small gear 63.

[0035] The clamping tooth plate 8 is slidably sleeved on the outer surface of the multi-rod frame 7, and the right end of the clamping tooth plate 8 is elastically connected with a rod plate 9, which is fixedly sleeved on the outer surface of the multi-rod frame 7. The front end of the rod plate 9 is a plate-like structure extending forward, and a reciprocating wire shaft 10 is arranged in front of each rod-like structure of the multi-rod frame 7. The outer surface of each reciprocating wire shaft 10 is threadedly sleeved with a transmission tooth plate 11, which meshes with the pinion 63 in turn when the transmission tooth plate 11 moves to the right. When the transmission tooth plate 11 meshes with a pinion 63, the threaded reciprocating screw rod 61 is driven to rotate and mesh with the meshing plate 52, and the oscillation sleeve 51 is driven to rotate multiple times. The back side of the transmission tooth plate 11 is elastically rotatably connected with an elastic shift plate 12. After the transmission tooth plate 11 is disengaged from the pinion 63, The transmission tooth plate 11 moves the plate-like structure of the rod plate 9 through the elastic shift plate 12, and drives multiple clamping tooth plates 8 to move synchronously through the multi-rod frame 7. A positioning plate 20 is fixed to the bottom surface of the clamping tooth plate 8. The positioning plate 20 is perpendicular to the adjacent clamping tooth plate 8. The bottom surface of the clamping tooth plate 8 is tangent to the adjacent large gear 62 below. The bottom surface of the transmission tooth plate 11 is meshed with the outer ring surface of the adjacent small gear 63 below. The clamping tooth plate 8 is meshed with the large gear 62 to drive the threaded reciprocating screw 61 to rotate. When the positioning plate 20 contacts the large gear 62, the threaded reciprocating screw 61 drives the oscillation sleeve 51 to move backward once through the meshing plate 52. At this time, the oscillation sleeve 51 presses the glass curtain wall to prevent the last vibration of the glass curtain wall from affecting the next vibration detection.

[0036] A fixing frame 13 is arranged in front of the multi-rod frame 7, and the fixing frame 13 is installed on the front of the test installation main board 1. A frame rod 17 is slidably sleeved on the upper surface of the transmission gear plate 11, and the frame rod 17 is fixed to the back side of the fixing frame 13. The frame rod 17 limits the moving trajectory of the transmission gear plate 11.

[0037] The elastic pick plate 12 and the plate-like structure of the rod plate 9 have an overlapping portion laterally. When the elastic pick plate 12 moves to the right, it can push the rod plate 9 to move. A convex structure is provided on the back of the transmission tooth plate 11 and on the left side of the elastic pick plate 12. The elastic pick plate 12 is elastically connected to the transmission tooth plate 11 and has a tendency to be perpendicular to the transmission tooth plate 11 under the joint action of the convex structure of the transmission tooth plate 11. When the transmission tooth plate 11 moves to the right, the elastic pick plate 12 can only move to the right side of the plate-like structure of the rod plate 9 by elastic deformation under the convex structure of the transmission tooth plate 11. When the transmission tooth plate 11 moves to the left, the elastic pick plate 12 moves to the left side of the plate-like structure of the rod plate 9 by rotation. The elasticity of the elastic pick plate 12 is greater than the elasticity of the elastic connection between the clamping tooth plate 8 and the rod plate 9.

[0038] The left and right ends of the reciprocating wire shaft 10 are rotatably connected to the fixed frame 13, and the left end of each reciprocating wire shaft 10 is fixedly sleeved with an end gear 14. A transmission threaded shaft 16 is arranged on the left side of the fixed frame 13. Both ends of the transmission threaded shaft 16 are rotatably connected to the front face of the test installation main board 1. The outer surface of the transmission threaded shaft 16 is threadedly sleeved with a main tooth plate 15, and the main tooth plate 15 is vertically arranged with the clamping tooth plate 8, and the clamping tooth plate 8 is parallel to the transmission tooth plate 11. The length of the main tooth plate 15 is less than the distance between two adjacent end gears 14, and the back side of the main tooth plate 15 is tangent to the outer ring surface of the end gear 14. When the main tooth plate 15 moves downward, the main tooth plate 15 meshes with the corresponding end gear 14 from top to bottom in turn, driving the multiple reciprocating wire shafts 10 distributed from top to bottom to rotate in turn and discontinuously.

[0039] The left and right sides of the main tooth plate 15 are in sliding contact with flat plates 18, and both ends of the flat plates 18 are fixed to the front side of the test installation main board 1. The two flat plates 18 limit the movement trajectory of the main tooth plate 15. A power motor 19 is arranged above the transmission threaded shaft 16. The power motor 19 is fixed to the test installation main board 1, and the output end of the power motor 19 is fixed to the transmission threaded shaft 16.

[0040] The working principle is as follows: the power motor 19 drives the transmission threaded shaft 16 to rotate and mesh with the main gear plate 15, drives the main gear plate 15 to move downward, and makes the main gear plate 15 mesh with the corresponding end gear 14 from top to bottom in turn, driving multiple reciprocating wire shafts 10 distributed from top to bottom to rotate in turn and discontinuously. During the rotation of a reciprocating wire shaft 10, the reciprocating wire shaft 10 meshes with the transmission gear plate 11, drives the transmission gear plate 11 to move from the left end to the right end, and when the transmission gear plate 11 moves to the right, it first meshes with the leftmost pinion 63, drives the threaded reciprocating screw rod 61 to mesh with the meshing plate 52, and the meshing plate 52 drives the oscillation sleeve 51 to reciprocately knock on the glass curtain wall through the elastic connection, so that the glass curtain wall vibrates, and the detection receiver 3 detects the oscillation through the detection head 4, and then after the transmission gear plate 11 is disengaged from the pinion 63, the transmission gear plate 11 is toggled through the elastic paddle 12 The plate-like structure with the rod plate 9 drives the multi-rod frame 7 to move to the right, and drives multiple clamping tooth plates 8 to engage with the large gear 62 through elastic connection. After the positioning plate 20 contacts the large gear 62, the clamping tooth plate 8 stops moving. At this time, the meshing plate 52 drives the oscillation sleeve 51 to move backward, driving the oscillation sleeve 51 to press the glass curtain wall, and controlling the vibration and pressing of the glass curtain wall to stop. Then, when the transmission tooth plate 11 continues to move, the elastic pick plate 12 is separated from the plate-like structure with the rod plate 9 through elastic deformation, and the multi-rod frame 7 is reset under the elastic connection with the test installation main board 1, so that the oscillation sleeve 51 is separated from the pressing on the glass curtain wall. Then, when the transmission tooth plate 11 moves, it drives the next oscillation structure 5 to oscillate the glass curtain wall. When the main tooth plate 15 moves downward to drive multiple oscillation sleeves 51 to perform oscillation detection of the glass curtain wall in turn, multiple positions of the glass curtain wall are detected.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
