Description

Technical Field

[0001] This invention relates to the field of scaffolding, and in particular to an axis displacement monitoring device. Background Technology

[0002] Currently, scaffolding is often used in the construction process. Scaffolding is a working platform erected to ensure the smooth progress of each construction process.

[0003] There are many types of scaffolding, among which coupler-type scaffolding is one of the most commonly used on construction sites. Coupler-type scaffolding consists of uprights and horizontal bars. Multiple vertical uprights and horizontal bars are connected by coupler joints, making the overall scaffolding structure more stable. Construction workers need to climb, stand, and walk on the scaffolding, so the stability of the scaffolding directly affects the personal safety of the construction workers. In the actual use of scaffolding, problems such as loosening of the connection between the couplers and the uprights, deformation of the uprights, and ground settlement may occur, causing the axis of the uprights to shift, thus making the scaffolding unstable and causing accidents such as collapse. Therefore, it is necessary not only to check the stability of the scaffolding when it is erected, but also to inspect the scaffolding during use.

[0004] During the use of scaffolding, workers usually use theodolites or measuring tapes to periodically check the horizontal displacement of the uprights to determine the scaffolding's deviation. However, there is a defect that the displacement detection of the uprights is not timely enough. If the scaffolding has a large horizontal displacement before the inspection, it will cause the scaffolding to twist or collapse, making it difficult to evacuate construction workers and repair the scaffolding in time, which may cause safety accidents. Summary of the Invention

[0005] To detect the displacement of the pole axis in real time, this invention provides an axis displacement monitoring device.

[0006] The axial displacement monitoring device provided by this invention adopts the following technical solution:

[0007] An axial displacement monitoring device includes a support assembly, a connecting assembly for connecting a pole and the support assembly, and a monitoring assembly for real-time monitoring of the axial displacement of the pole. The support assembly includes a support housing located between two poles and fixedly connected to them. The connecting assembly is connected to both the pole and the support housing. The monitoring assembly is connected to both the support housing and the connecting assembly. Two sets of the connecting assembly and the monitoring assembly are provided, with each set of the connecting assembly and each set of the monitoring assembly connected to one pole.

[0008] By adopting the above technical solution, the support shell can provide stable support for the monitoring component. The connecting component connects the upright to the support component and can feed back the displacement of the upright axis to the monitoring component, so that the monitoring component can detect the horizontal displacement of the upright axis in real time, thereby detecting the horizontal displacement of the upright axis as soon as possible and prompting the staff to carry out maintenance or evacuate the construction personnel on the scaffolding in a timely manner.

[0009] Preferably, observation windows are provided on both sides of the support housing along its length. The monitoring component includes a monitoring rod and a monitoring pointer. One end of the monitoring rod, which moves synchronously with the upright, is hinged to the monitoring pointer, and the other end is connected to the connecting component. The monitoring pointer is rotatably connected to the support housing. A partition is connected inside the support housing, which divides the interior of the support housing into two spaces. The side of the partition near the observation window is provided with multiple indicator areas for observing the tilt of the upright.

[0010] By adopting the above technical solution, since the monitoring rod and the monitoring pointer are hinged, when the axis of the upright is horizontally offset, the monitoring rod will move, causing the monitoring pointer to rotate. The staff can judge the offset of the upright axis by observing which area the monitoring pointer moves to in the observation window, so as to repair the upright in time or evacuate the personnel from the scaffold.

[0011] Preferably, the connecting assembly includes a connecting rod and a connecting slider. One end of the connecting rod is connected to the upright, and the other end is hinged to the connecting slider. The supporting housing is provided with a corresponding groove for the connecting slider to slide. The end of the monitoring rod away from the monitoring pointer is hinged to the connecting slider.

[0012] By adopting the above technical solution, the connecting rod is connected to the upright and the connecting slider respectively, and the connecting slider is connected to the monitoring rod. When the axis of the upright is horizontally displaced, the connecting rod moves with the upright, thereby driving the connecting slider to slide, causing the monitoring rod to rotate, driving the monitoring pointer to rotate, and moving the monitoring pointer to the corresponding indication area, so that the staff can observe the displacement of the axis of the upright in real time and react in a timely manner.

[0013] Preferably, the monitoring component further includes a first micro switch, a second micro switch, a warning light, and a speaker. The monitoring pointer is connected to the first micro switch for controlling the warning light and the second micro switch for controlling the speaker. Two first micro switches are symmetrically arranged along the observation window inside the support housing, and two second micro switches are correspondingly arranged. The two second micro switches are located on opposite sides of the first micro switches. The first micro switch is connected to a control module, and the control module is electrically connected to the first micro switch, the second micro switch, the warning light, and the speaker.

[0014] By adopting the above technical solution, when the monitoring pointer rotates, it drives the first or second micro switch to open, thereby activating the warning light or speaker. Depending on the deviation of the upright axis, the first micro switch is activated first, causing the warning light to flash, reminding workers to inspect the upright in time. Since the second micro switch is located on the side away from the first micro switch, when the deviation of the upright is large, the second micro switch is activated, and the speaker plays an alarm audio, reminding the construction workers on the scaffold to leave the scaffold in time. This achieves the effect of real-time monitoring of the deviation of the upright axis and reduces safety hazards.

[0015] Preferably, the monitoring component further includes a rotating shaft, which is fixedly connected to the end of the monitoring pointer away from the observation window, and is rotatably connected to the inner wall of the support housing. The rotating shaft is also fixedly connected to a first control board for switching the first micro switch and a second control board for switching the second micro switch.

[0016] By adopting the above technical solution, when the rotating shaft follows the monitoring pointer, the first control board and the second control board rotate simultaneously to sequentially open the first micro switch and the second micro switch, thereby controlling the opening and closing of the warning light and the loudspeaker according to the magnitude of the horizontal displacement of the upright axis, so as to remind construction personnel to inspect the scaffold or stay away from the scaffold.

[0017] Preferably, the supporting housing is connected to a solar panel and a battery, and the solar panel and the battery are electrically connected to the first micro switch, the second micro switch, the warning light, the speaker and the control module, respectively.

[0018] By adopting the above technical solution, when the support shell is installed between the poles, the solar power panel converts solar energy into electrical energy and stores it in the battery, so that the battery continuously stores electrical energy to power the warning lights and speakers to work normally, and can monitor the horizontal displacement of the pole axis in real time for a long time.

[0019] Preferably, the connecting assembly includes a clamping buckle and a connecting bolt. The clamping buckle is detachably connected to the upright. The clamping buckle is connected to a mounting rod, which has a mounting hole. An alignment sleeve is connected to the end of the connecting rod away from the connecting slider. The alignment sleeve has an alignment hole. The connecting bolt passes through the mounting hole and the alignment hole respectively and is threadedly connected to the mounting rod.

[0020] By adopting the above technical solution, the mounting rod is inserted into the alignment sleeve, and the alignment hole is connected to the mounting hole. The connecting bolts are then inserted into the alignment hole and the mounting hole respectively, so that the connecting bolts are threadedly connected to the mounting rod. This allows the clamping buckle to be quickly connected to the connecting rod, so that when the column axis undergoes horizontal displacement, it can drive the connecting rod to move, thereby causing the monitoring pointer to rotate. This makes it convenient for staff to observe the displacement of the column axis in real time.

[0021] Preferably, the support assembly includes support columns and reinforcing plates. Multiple support columns are provided, and the multiple support columns are fixedly connected to the support shell. The other end of each support column is connected to the reinforcing plate, and the cross-sectional area of ​​the reinforcing plate is larger than the cross-sectional area of ​​the support column.

[0022] By adopting the above technical solutions, the support column can provide stable support for the support shell, making it less likely for the support shell to shift position. The reinforcement plate can increase the contact area between the support column and the ground, making the support column more stable and reducing the monitoring error caused by the shaking of the support shell.

[0023] Preferably, the top surface of the support housing is provided with a bubble window for assisting in observing whether the support housing is level.

[0024] By adopting the above technical solution, the bubble window makes it easier for staff to observe whether the support housing is level during installation, ensuring that the support housing is always in a horizontal position, reducing the error between the actual rotation angle of the monitoring pointer and the monitored deviation angle caused by the tilt of the support housing, and improving the efficiency of real-time monitoring.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The support shell can stably support the connecting components and the monitoring components, which facilitates the monitoring components to monitor the displacement of the pole axis in real time and make timely adjustments based on the displacement to reduce safety hazards; the connecting components are connected to the support shell and the monitoring components respectively, and can feed back the displacement to the monitoring components when the pole axis undergoes horizontal displacement, thus achieving the effect of real-time monitoring.

[0027] 2. When the upright axis deviates horizontally, it can drive the connecting rod and connecting slider to move, thereby driving the monitoring rod and monitoring pointer to move. By observing the rotation of the monitoring pointer in the observation window, the staff can judge the displacement of the upright axis in real time, and thus make certain adjustments to the scaffolding to reduce the occurrence of its deviation and torsion, and improve the safety of the scaffolding. The rotating shaft drives the first control plate and the second control plate to abut against the first micro switch and the second micro switch respectively, which can make the warning light or speaker work, thereby reminding the staff to inspect the upright or evacuate the construction personnel on the scaffolding in time.

[0028] 3. The support shell is located between the uprights for long-term monitoring of the uprights. The solar panels connected to the support shell can convert solar energy into electrical energy, and the battery can store electrical energy to power the warning lights and speakers continuously.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] An axial displacement monitoring device, such as Figure 1 As shown, it includes a support component 2, a connection component 3, a monitoring component 4, a control module, and a solar panel 5. The connection component 3 is connected to the support component 2 and the pole 1 respectively. The monitoring component 4 is connected to the connection component 3 and the support component 2 respectively to monitor the horizontal displacement of the pole 1 axis in real time. The control module is connected to the monitoring component 4. The solar panel 5 is connected to the support shell 21 and the monitoring component 4 respectively to continuously provide power.

[0039] like Figure 1 As shown, the support assembly 2 includes a support housing 21, a partition 22, a support column 23, and a reinforcing plate 24. The support housing 21 is located between two vertical uprights 1. A bubble window 211 for detecting whether the support housing 21 is horizontal is fixedly connected to the top surface of the support housing 21. The partition 22 is located inside the support housing 21 and is fixedly connected to the support housing 21. The axis of symmetry of the partition 22 in the length direction coincides with the axis of symmetry in the length direction of the support housing 21, dividing the support housing 21 into two parts.

[0040] like Figure 1 As shown, multiple vertical support columns 23 are provided, and the multiple support columns 23 are fixedly connected to the bottom surface of the support shell 21. The reinforcing plate 24 is a horizontal plate structure with a cross-sectional area larger than that of the support column 23. Multiple reinforcing plates 24 are provided, and the multiple reinforcing plates 24 are fixedly connected to the bottom surface of the support column 23 respectively. Multiple reinforcing bolts 241 are connected to the reinforcing plate 24. The multiple reinforcing bolts 241 pass through the reinforcing plate 24 and are threadedly connected to the reinforcing plate 24 to enhance the stability of the connection between the reinforcing plate 24 and the ground.

[0041] like Figure 1 and Figure 2 As shown, there are two sets of connecting components 3, which are symmetrically arranged about the center of the partition 22. The connecting components 3 include clamping buckles 31, connecting rods 32, connecting bolts 33, and connecting sliders 34. The clamping buckles 31 are buckle structures made of elastic material. Each set of connecting components 3 is provided with one clamping buckle 31. The clamping buckle 31 includes a fixing part and a snap-fit ​​part. The fixing part is a cuboid structure with a circular hole on the top surface. The fixing part passes through one of the uprights 1 and is slidably connected to the upright. The snap-fit ​​part includes two vertical plate-like structures. The snap-fit ​​part is located on one side of the fixing part and is fixedly connected to the fixing part. The clamping buckle 31 is connected to a clamping bolt 311. The clamping bolt 311 passes through the snap-fit ​​part and is threadedly connected to the snap-fit ​​part to make the clamping buckle 31 tightly connected to the upright 1.

[0042] like Figure 2 As shown, a mounting rod 312 is fixedly connected to the side of the clamping buckle 31 away from the clamping bolt 311. The mounting rod 312 has a mounting hole 3121. One end of the connecting rod 32 is fixedly connected to an alignment sleeve 321. The diameter of the alignment sleeve 321 is larger than the diameter of the mounting rod 312, so that the alignment sleeve 321 can be inserted into the mounting rod 312. The alignment sleeve 321 has a corresponding alignment hole 3211. When the mounting rod 312 is located inside the alignment sleeve 321, the connecting bolt 33 passes through the alignment hole 3211 and the mounting hole 3121 respectively and is threadedly connected to the mounting rod 312, so that the clamping buckle 31 is connected to the connecting rod 32.

[0043] like Figure 3 and Figure 4 As shown, the end of the connecting rod 32 away from the alignment sleeve 321 is slidably connected to the support housing 21. The side of the support housing 21 near the connecting rod 32 is provided with a connecting groove 212 for the connecting rod 32 to slide. The connecting slider 34 is hinged to the side of the connecting rod 32 near the support housing 21 by a hinge rod. The connecting slider 34 is located inside the support housing 21 and is slidably connected to the support housing 21. The inside of the support housing 21 is provided with a sliding groove 213 for the connecting slider 34 to slide. The connecting groove 212 and the sliding groove 213 are connected, and the length direction of the connecting groove 212, the length direction of the sliding groove 213, and the length direction of the support housing 21 are parallel.

[0044] like Figure 3 and Figure 4 As shown, two sets of monitoring components 4 are provided, and the two sets of monitoring components 4 are symmetrically arranged about the center of the partition 22 (refer to...). Figure 1 It includes a monitoring rod 41, a monitoring pointer 42, a rotating shaft 43, a first micro switch 44, a second micro switch 45, a warning light 46, and a speaker 47.

[0045] like Figure 4 and Figure 5As shown, the monitoring rod 41 is located inside the support housing 21 and is slidably connected to the support housing 21. The top surface of the connecting slider 34 is fixedly connected to the hinge block 341. One end of the monitoring rod 41 is hinged to the hinge block 341. The support housing 21 is provided with a monitoring groove 214 for the hinge block 341 to slide. The monitoring groove 214 is connected to the connecting groove 212, and the length direction of the monitoring groove 214 is parallel to the length direction of the connecting groove 212.

[0046] like Figure 5 and Figure 6 As shown, one end of the monitoring pointer 42 is equipped with an arrow, and the other end is fixedly connected to the rotating shaft 43. The rotating shaft 43 is located inside the support housing 21 and is rotatably connected to the support housing 21. The end of the monitoring rod 41 away from the connecting slider 34 is hinged to the monitoring pointer 42. When the connecting slider 34 slides in the slide groove 213, the monitoring rod 41 rotates, causing the monitoring pointer 42 and the rotating shaft 43 to rotate around the axis of the rotating shaft 43. The support base has an arc-shaped observation window 215, so that the end of the monitoring pointer 42 with the arrow is located in the observation window 215. The partition 22 is provided with an indicator area for indicating the offset of the axis of the upright 1. The indicator area from the center line of the partition 22 outwards is the green safety area, the yellow warning area, and the red danger area.

[0047] In use, move the support housing 21 between the two uprights 1 and observe the bubbles in the bubble window 211 to determine whether the support housing 21 is level. After adjusting the support housing 21 to be level, use the reinforcing bolts 241 to stably connect the reinforcing plate 24 to the ground. The support column 23 provides stable support for the support housing 21. Engage the clamping buckles 31 with the uprights 1 respectively, and move the clamping buckles 31 to a suitable height. Tighten the clamping bolts 311 to make the fixing part of the clamping buckles 31 tightly abut against the uprights 1, restricting the position of the clamping buckles 31 on the uprights 1. Then, put the alignment sleeve 321 on the mounting rod 312 so that the mounting hole 3121 and the alignment hole 3211 coincide. Let the connecting bolts 33 pass through the mounting hole 3121 and the alignment hole 3211 respectively to achieve the effect of connecting the clamping buckles 31 and the connecting rod 32.

[0048] When the axis of one of the uprights 1 experiences horizontal displacement, the connecting rod 32 connected to the upright 1 drives the connecting slider 34 to slide within the groove 213, causing the monitoring rod 41, which is hinged to the connecting slider 34, to rotate. This, in turn, causes the monitoring pointer 42 to rotate. By observing the position of the monitoring pointer 42 within the observation window 215 and which indication area the monitoring pointer 42 is located in, workers can determine the displacement of the axis of the upright 1. When the monitoring pointer 42 is located in the green safety zone, the horizontal displacement of the axis of the upright 1 is small, and construction workers can work on the scaffold. When it is located in the yellow warning zone, the upright 1 needs to be inspected to reduce its horizontal displacement and ensure the normal progress of construction work. When it is located in the red danger zone, there is a significant risk of scaffold displacement, and construction workers on the scaffold should be evacuated in time, and the upright 1 should be repaired.

[0049] like Figure 5 and Figure 6 As shown, the first micro switch 44 and the second micro switch 45 are both located inside the support housing 21 and are fixedly connected to the support housing 21. The support housing 21 has a placement slot 216 for placing the first micro switch 44 and the second micro switch 45. The placement slot 216 is connected to the monitoring slot 214. The support housing 21 is connected to a placement block 217, which is located in the placement slot 216 and fixedly connected to the support housing 21. There are two placement blocks 217, which are symmetrically placed on both sides of the axis of the rotating shaft 43. There are two first micro switches 44, which are symmetrically arranged about the axis of the rotating shaft 43. They are located above the placement blocks 217 and fixedly connected to the placement blocks 217. The switching parts of the first micro switches 44 are close to the rotating shaft 43. The rotating shaft 43 is fixedly connected to a first control plate 431 for controlling the opening or closing of the first micro switches 44. When the first control plate 431 rotates with the rotating shaft 43 to a certain angle, it abuts against the first micro switch 44 and can open the first micro switch 44.

[0050] like Figure 5 and Figure 6 As shown, two second microswitches 45 are provided. The two second microswitches 45 are respectively arranged about the axis of the rotation shaft 43. The second microswitches 45 are respectively located on the side of the first microswitches 44 that are far away from each other and are fixedly connected to the placement block 217. The first microswitches 44 and the second microswitches 45 connected on the same placement block 217 are staggered. A second control plate 432 is fixedly connected to the rotation shaft 43. The second control plate 432 is located on the side of the first control plate 431, and the length of the second control plate 432 is greater than that of the first control plate 431. When the rotation shaft 43 rotates to a certain angle, the second control plate 432 abuts against the switching part of the second microswitches 45, thereby opening the second microswitches 45.

[0051] like Figure 6As shown, the warning light 46 and the speaker 47 are both located above the support housing 21 and are fixedly connected to the top surface of the support housing 21. The warning light 46 in the same monitoring assembly 4 is electrically connected to two first micro switches 44 respectively, and the speaker 47 is electrically connected to two second micro switches 45 respectively.

[0052] like Figure 6 As shown, the control module is electrically connected to the first micro switch 44, the second micro switch 45, the warning light 46, and the speaker 47 respectively. When the first micro switch 44 is turned on, the warning light 46 flashes. When the second micro switch 45 is turned on, the speaker 47 plays an alarm audio.

[0053] like Figure 6 As shown, multiple solar panels 5 are provided. The multiple solar panels 5 are located above the support housing 21 and are fixedly connected to the top surface of the support housing 21. The solar panels 5 are electrically connected to a battery (not shown in the figure). The battery is electrically connected to the first micro switch 44, the second micro switch 45, the warning light 46, the speaker 47, and the control module, respectively, to provide stable and continuous power.

[0054] The process of using this invention is as follows:

[0055] In use, install the support housing 21 between the two uprights 1. By observing the bubble window 211, adjust the support housing 21 to keep it level. Attach the clamping buckles 31 to the two uprights 1 respectively and adjust them to the appropriate positions. Tighten the clamping bolts 311 to fix the clamping buckles 31 in their respective positions on the two uprights 1. Let the connecting bolts 33 pass through the mounting holes 3121 and the alignment holes 3211 respectively, and connect the clamping buckles 31 to the connecting rod 32.

[0056] When the axis of the upright pole 1 shifts horizontally, the clamping buckle 31 and the connecting rod 32 also shift, causing the connecting slider 34 to slide within the connecting groove 212. The connecting slider 34 drives the monitoring rod 41 to rotate. The end of the monitoring rod 41 near the monitoring pointer 42 drives the monitoring pointer 42 to rotate along the axis of the rotating shaft 43, thus rotating it to different indicating areas. The staff can observe the position of the monitoring pointer 42 through the observation window 215 and determine the horizontal displacement of the axis of the upright pole 1.

[0057] When the monitoring pointer 42 is in the green safety zone, it indicates that the offset of the axis of the upright 1 is within a safe range, and construction workers can work normally on the scaffold. When the monitoring pointer 42 rotates into the yellow warning zone, the first control board 431 rotates with the rotating shaft 43 until it comes into contact with the first micro switch 44 and turns on the first micro switch 44. The first micro switch 44 sends an electrical signal to the control module, and the control module controls the warning light 46 to flash, prompting the workers to inspect the upright 1. When the monitoring pointer 42 rotates into the red danger zone, the rotating shaft 43 drives the second control board 432 to rotate until it comes into contact with the switch part of the second micro switch 45, and the speaker 47 is activated to broadcast an alarm audio. Under the action of the first control board 431, the warning light 46 flashes continuously, promptly evacuating the construction workers working on the scaffold and allowing the upright 1 to be repaired.

[0058] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
