Description

Technical Field

[0001] This invention relates to the field of engineering safety technology, and in particular to a deformation monitoring device for cantilever scaffolding. Background Technology

[0002] Cantilevered scaffolding is a temporary facility used in construction to provide a safe and reliable working platform when working at heights. Deformation monitoring of cantilevered scaffolding is one of the important measures to ensure construction safety. By regularly monitoring the scaffolding, potential hazards can be detected in time, providing a basis for construction safety management and ensuring the smooth progress of the project. At the same time, it is necessary to analyze the monitoring data to understand the deformation trend of the cantilevered scaffolding.

[0003] Existing cantilever scaffold deformation monitoring devices need to be connected to the top of the cantilever scaffold before operation. However, during construction, the placement of these devices can affect workers' work and may cause damage to the devices. Furthermore, when the cantilever scaffold shifts, existing deformation monitoring devices can only issue an alarm but cannot accurately confirm the direction of the shift in time, making it difficult to take quick action. Consequently, it is difficult to better predict subsequent accidents. Summary of the Invention

[0004] The purpose of this invention is to provide a deformation monitoring device for cantilever scaffolding in order to solve the above-mentioned problems. By setting a contact sensor to slide on the outer surface of the smooth pole, and then the contact sensor contacts the moving block, the safety alarm at both ends of the smooth pole is activated, thus solving the problems mentioned in the background art.

[0005] To address the above problems, the present invention provides a technical solution: A deformation monitoring device for cantilever scaffolding includes a sliding plate, a sleeve plate, and a smooth pole. The surface of the sliding plate is slidably connected to the interior of the sleeve plate. A connecting shell is fixedly installed at the bottom of the sleeve plate. Two bending components are disposed inside the connecting shell. An outer shell is fixedly installed at the bottom of the connecting shell. One end of the smooth pole penetrates the side of the outer shell. Safety alarms are fixedly installed at both ends of the smooth pole. Support components are disposed on the surfaces of the two safety alarms. Two springs are movably fitted on the surface of the smooth pole. The disjoint ends of the two springs are fixedly installed on the inner walls of the outer shell. Movable blocks are fixedly installed at the adjacent ends of the two springs. First bolts are movably connected to the tops of the two movable blocks. One end of each of the first bolts penetrates the top of the movable block and fits tightly against the outer surface of the smooth pole. A contact sensor is fixedly installed at the bottom of the connecting shell. The bottom of the contact sensor is movably fitted onto the outer surface of the smooth pole. Fixing frames are fixedly installed on the tops of the sliding plate and the sleeve plate. Hanging components are disposed inside the two fixing frames.

[0006] In a preferred embodiment of the present invention, the support assembly includes a sleeve rod, one end of which penetrates the surface of the safety alarm. A threaded rod is threadedly connected to the inside of the sleeve rod, a knob is fixedly installed at one end of the threaded rod, and a support plate is movably connected to the end of the threaded rod away from the knob.

[0007] In a preferred embodiment of the present invention, a disc is fixedly installed at one end of the threaded rod near the support plate, and a sleeve is fixedly installed at one end of the support plate, with the outer surface of the disc movably connected to the interior of the sleeve.

[0008] As a preferred embodiment of the present invention, two through slots are provided on the side of the connecting shell, a bending detector is fixedly installed inside the connecting shell, and sliding grooves are respectively provided on the top of the sliding plate and the sleeve plate. Double-ended bolts are slidably connected inside the sliding grooves, and first nuts are movably connected to both ends of the double-ended bolts.

[0009] In a preferred embodiment of the present invention, the bending assembly includes an arc-shaped shell, the side of which is fixedly mounted on one side of the bending detector. An arc-shaped groove is formed inside the arc-shaped shell, and two second arc-shaped plates are slidably connected inside the arc-shaped groove. A support rod is fixedly mounted on the adjacent side of the two second arc-shaped plates. A straight rod is fixedly mounted on the surface of the support rod away from the bending detector, and a first arc-shaped plate is fixedly mounted on the top end of the straight rod.

[0010] As a preferred embodiment of the present invention, a fixing ring is fixedly sleeved on the outer surface of the support rod, and two rotating columns are rotatably connected to the side of the fixing ring. The two rotating columns are respectively fixedly installed on the inner sides of the through groove.

[0011] In a preferred embodiment of the present invention, the mounting assembly includes a shaft, two first collars are movably sleeved on the outer surface of the shaft, a first connecting rod is fixedly mounted on the surface of the two first collars, a second half-cylinder is fixedly mounted on the top of the two first connecting rods, a second collar is disposed between the two first collars, the interior of the second collar is movably connected to the outer surface of the shaft, a second connecting rod is fixedly mounted on the top of the second collar, and a first half-cylinder is fixedly mounted on the top of the second connecting rod.

[0012] As a preferred embodiment of the present invention, the outer surfaces of the first half-cylinder and the second half-cylinder are respectively fixedly mounted with fixing plates, and the sides of the two fixing plates are rotatably connected with second bolts, and the outer surfaces of the second bolts are threaded with second nuts.

[0013] The beneficial effects of the present invention are: 1. By fixing the support components to the wall, adjusting the top sliding plate and sleeve plate, and fixing the top-mounted hanging components to the suspended scaffolding pipe, the hanging components and the support components form a 90-degree angle, which can better fix them to the suspended scaffolding and will not affect the progress of the project construction.

[0014] 2. When the installed housing shifts, the internally installed contact sensor slides on the outer surface of the rod. The contact sensor then contacts the moving block. Since the moving block is fixed to the surface of the rod by the first bolt at the top, when contact occurs, the safety alarm installed at one end sounds an alarm and the alarm light turns on. This allows for immediate detection of the situation and also indicates which side has shifted, thus reducing the occurrence of accidents. Attached Figure Description

[0018] like Figures 1-7 As shown, the specific implementation adopts the following technical solution: Example

[0019] A deformation monitoring device for cantilever scaffolding includes a sliding plate 1, a sleeve plate 2, and a smooth rod 14. The surface of the sliding plate 1 is slidably connected to the interior of the sleeve plate 2. A connecting shell 6 is fixedly installed at the bottom of the sleeve plate 2. Two bending components 7 are arranged inside the connecting shell 6. An outer shell 8 is fixedly installed at the bottom of the connecting shell 6. One end of the smooth rod 14 passes through the side of the outer shell 8. Safety alarms 11 are fixedly installed at both ends of the smooth rod 14. When the safety alarms 11 contact the moving block 19, they will immediately trigger an audible and visual alarm. Support components 12 are respectively provided on the surface of the two safety alarms 11. Two springs 18 are movably sleeved on the surface of the smooth rod 14. The springs 18... The purpose is to ensure that the two moving blocks 19 can be aligned when resetting. The two springs 18 are respectively fixedly installed on the inner walls of the outer shell 8 at their opposite ends. The moving blocks 19 are fixedly installed on the adjacent ends of the two springs 18. The tops of the two moving blocks 19 are movably connected to the first bolts 17. One end of the two first bolts 17 passes through the top of the moving blocks 19 and fits tightly against the outer surface of the light rod 14. The bottom of the connecting shell 6 is fixedly installed with a contact sensor 16. The bottom of the contact sensor 16 is movably sleeved on the outer surface of the light rod 14. The tops of the slide plate 1 and the sleeve plate 2 are respectively fixedly installed with a fixing frame 20. The inside of the two fixing frames 20 is provided with a hanging component 13.

[0020] Furthermore, the support assembly 12 includes a sleeve rod 123, one end of which penetrates the surface of the safety alarm 11. A threaded rod 122 is threaded inside the sleeve rod 123. The sleeve rod 123 has threads inside and corresponds to the threaded rod 122. A knob 10 is fixedly installed at one end of the threaded rod 122. A support plate 121 is movably connected to the end of the threaded rod 122 away from the knob 10. The support plate 121 has multiple grooves on its contact surface with the wall to increase friction.

[0021] Furthermore, a disc 124 is fixedly installed at one end of the threaded rod 122 near the support plate 121, and a sleeve 125 is fixedly installed at one end of the support plate 121. The outer surface of the disc 124 is movably connected to the interior of the sleeve 125.

[0022] Furthermore, two through slots 9 are provided on the side of the connecting shell 6, and a bending detector 15 is fixedly installed inside the connecting shell 6. Slide grooves 5 are provided on the top of the slide plate 1 and the sleeve plate 2 respectively. Double-headed bolts 4 are slidably connected inside the slide grooves 5, and first nuts 3 are movably connected to both ends of the double-headed bolts 4.

[0023] Furthermore, the bending assembly 7 includes an arc-shaped shell 74, the side of which is fixedly installed on one side of the bending detector 15. An arc-shaped groove 75 is provided inside the arc-shaped shell 74. Two second arc-shaped plates 76 are slidably connected inside the arc-shaped groove 75. The two second arc-shaped plates 76 slide on the arc-shaped groove 75. A support rod 73 is fixedly installed on the adjacent side of the two second arc-shaped plates 76. A straight rod 72 is fixedly installed on the surface of the end of the support rod 73 away from the bending detector 15. A first arc-shaped plate 71 is fixedly installed at the top of the straight rod 72. The first arc-shaped plate 71 can adapt to scaffolding pipes of various diameters.

[0024] Furthermore, a fixing ring 24 is fixedly sleeved on the outer surface of the support rod 73. Two rotating columns 25 are rotatably connected to the side of the fixing ring 24. The two rotating columns 25 are respectively fixedly installed on the two sides inside the through groove 9.

[0025] Furthermore, the mounting assembly 13 includes a shaft 131, with two first collars 135 movably sleeved on the outer surface of the shaft 131. A first connecting rod 134 is fixedly mounted on the surface of the two first collars 135, and a second half-cylinder 133 is fixedly mounted on the top of the two first connecting rods 134. A second collar 136 is provided between the two first collars 135, and the interior of the second collar 136 is movably connected to the outer surface of the shaft 131. A second connecting rod 137 is fixedly mounted on the top of the second collar 136, and a first half-cylinder 132 is fixedly mounted on the top of the second connecting rod 137. When the first half-cylinder 132 and the second half-cylinder 133 are connected and in contact, they form a movable cylinder and can be disassembled and replaced.

[0026] Furthermore, fixing plates 23 are fixedly installed on the outer surfaces of the first half-cylinder 132 and the second half-cylinder 133, and second bolts 22 are rotatably connected to the sides of the two fixing plates 23. The outer surface of the second bolts 22 is threaded with a second nut 21. Example

[0027] In summary: When using this device, first loosen the first nuts 3 at both ends of the double-ended bolt 4, then adjust the distance between the slide plate 1 and the sleeve plate 2. When the distance is appropriate, rotate the first nuts 3 at both ends of the double-ended bolt 4 to fix it. Then, rotate the second half-cylinder 133 to move the first connecting rod 134. The first connecting rod 134 causes the first collar 135 at the bottom to rotate on the surface of the shaft 131. Rotate the first half-cylinder 132 to move, which in turn causes the second connecting rod 137 to move. The second connecting rod 137 then causes the second collar 136 at the bottom to rotate on the shaft 131. 31. Surface rotation occurs, at which point the first half-cylinder 132 and the second half-cylinder 133 engage on the scaffolding pipe. The second bolt 22 is inserted into the two fixing plates 23, and then the second nut 21 is rotated to fix the second bolt 22. Rotating the knob 10 drives the threaded rod 122 to rotate. The threaded rod 122 rotates inside the sleeve rod 123 and then moves, driving the disc 124 at the other end to move. The disc 124 drives the support plate 121 to move, and the support plate 121 supports the wall surface. Grooves are provided where the support plate 121 contacts the wall surface. Then the second... An arc-shaped plate 71 is placed at the bottom of the scaffold tube. When the cantilevered scaffold shifts, the scaffold moves the fixed frame 20, which in turn moves the bottom-mounted sliding plate 1 and sleeve plate 2. The sleeve plate 2 causes the bottom connecting shell 6 to shift, and the connecting shell 6 causes the bottom outer shell 8 to slide on the surface of the smooth pole 14. Since the first bolt 17 fixes the moving block 19 to the smooth pole 14, when the scaffold shifts, the contact sensor 16 will contact the moving blocks 19 on both sides. At this time, the safety alarm 11 at both ends of the smooth pole 14 will activate, emitting sound and alarm light. When the scaffolding pipe bends, it moves downwards, which in turn moves the first arc plate 71. The first arc plate 71 moves the bottom straight rod 72, which in turn moves the support rod 73. Since the support rod 73 is fixedly fitted with a fixing ring 24, it will cause the two rotating columns 25 on the side to rotate. The second arc plate 76 installed at one end of the support rod 73 slides in the arc groove 75 inside the arc shell 74. When sliding occurs and reaches a dangerous value, the data will be sent to the bending detector 15, and the staff will be able to detect it in time and make appropriate adjustments.
