Description

Technical Field

[0002] Scaffolding is a working platform set up to ensure the smooth progress of various construction processes. It is a sub-project with certain risks in the field of construction. For high-rise scaffolding with a height of more than 15m, there must be design, calculation, detailed drawings, erection plan, approval by the technical person in charge of the next level, and written safety technical instructions. For dangerous and special hanging, lifting, hanging, plugging and stacking racks, they must also be designed and approved, and separate safety technical measures must be prepared before they can be erected.

[0042] Please refer to Figure 1-Figure 3 , this embodiment provides a scaffolding support system 200, the scaffolding support system 200 includes a plurality of scaffolding steel pipes 211 and at least one scaffolding monitoring device 100;

[0043] A plurality of scaffolding steel pipes 211 are overlapped to form a scaffolding 210 through connectors, and a scaffolding monitoring device 100 is arranged at the overlap of two adjacent scaffolding steel pipes 211;

[0044] The scaffold monitoring device 100 includes a main body 110, a movable tube 120, a support assembly 130 and a monitoring assembly 140;

[0045] The movable tube 120 is coaxially arranged with the main body 110, and one end of the movable tube 120 is movably arranged in the main body 110, and the other end of the movable tube 120 is used to connect with the external scaffolding steel pipe 211; the end of the main body 110 away from the movable tube 120 is used to connect with the external scaffolding steel pipe 211;

[0046] The support assembly 130 is disposed in the main body 110, and is used to abut against one end of the movable tube 120 located in the main body 110, so as to support the movable tube 120 and drive the movable tube 120 to move relative to the main body 110 along the axial direction of the main body 110;

[0047] The monitoring assembly 140 is disposed in the main tube 110 , and is used to monitor the displacement of the movable tube 120 relative to the main tube 110 , and the pressure exerted by the movable tube 120 on the supporting assembly 130 .

[0048] It should be noted that when configuring the above-mentioned scaffolding monitoring device 100, it is capable of monitoring the force and displacement of the installation position. Therefore, during use, the number of scaffolding monitoring devices 100 and the corresponding installation positions can be selected according to the construction plan of the scaffolding 210. In the present embodiment, it is taken as an example to illustrate that it is installed at two vertically arranged scaffolding steel pipes 211; in other embodiments of the invention, it can also be set at other positions of the scaffolding 210.

[0049] For details, please refer to Figure 1-Figure 3 The working principle of the scaffold support system 200 equipped with the scaffold monitoring device 100 is as follows:

[0050] First, the scaffold support system 200 includes a scaffold 210 constructed of a plurality of scaffold steel pipes 211, and a scaffold monitoring device 100 is disposed at some positions according to the construction plan;

[0051] When installing the scaffold monitoring device 100, since the main body 110 and the movable tube 120 are coaxially arranged, when the main body 110 and the movable tube 120 are connected to the scaffold steel pipes 211 at the corresponding positions, the two ends of the main body 110 and the movable tube 120 that are separated from each other can be respectively connected to the ends of two adjacent scaffold steel pipes 211;

[0052] Moreover, when the main body 110 and the movable tube 120 are connected to the corresponding scaffolding steel tube 211, the main body 110 and the movable tube 120 can be inserted into the scaffolding steel tube 211 or sleeved on the scaffolding steel tube 211 by adjusting the corresponding diameter of the main body 110 and the movable tube 120. When the main body 110 and the movable tube 120 are fixed to the scaffolding steel tube 211, the connection between them can be fixed by a buckle or a pin to provide installation stability. In this embodiment, due to the use of The movable tube 120 is partially inserted into the main tube body 110. Therefore, the diameter of the main tube body 110 is larger than that of the movable tube 120. Therefore, during the installation process, the end of the movable tube 120 used for connecting with the scaffolding steel tube 211 is inserted into the scaffolding steel tube 211, and the main tube body 110 is sleeved on the scaffolding steel tube 211. In addition, the main tube body 110 and the movable tube 120 are fixedly connected to the scaffolding steel tube 211 by a pin shaft.

[0053] During use, the scaffold monitoring device 100 can be used as a structural member connecting two adjacent scaffold steel pipes 211. Since the main body 110 and the movable pipe 120 are respectively connected to the two scaffold steel pipes 211, if there is a relative displacement between the two adjacent scaffold steel pipes 211, the movement of the movable pipe 120 relative to the main body 110 can be monitored by the monitoring component 140, and then the relative displacement can be monitored. At the same time, the force between the two scaffold steel pipes 211 can be monitored by monitoring the force between the two, that is, monitoring the pressure of the movable pipe 120 on the supporting component 130, so as to monitor the force between the two scaffold steel pipes 211. Through the above-mentioned monitoring, the interaction force of the scaffold steel pipes 211 in the planned monitoring position in the scaffold 210 can be monitored, and the relative displacement between the two can also be monitored, so as to assist the construction personnel to fully understand the working status of the scaffold 210, and then facilitate the construction personnel to evaluate the stability and safety of the scaffold 210 as a whole.

[0054] In addition, during the use of the scaffold monitoring device 100, the movable tube 120 can be supported by the support assembly 130, and the movable tube 120 can be driven to move along the axis of the main body 110 by the support assembly 130, so as to adjust the length of the connecting member formed by the movable tube 120 and the main body 110 to meet the connection requirements at different installation positions, and then when the spacing between two adjacent scaffold steel pipes 211 changes, the movable tube 120 can be driven to extend into or out of the main body 110 by the support assembly 130, so as to adjust the overall length of the scaffold monitoring device 100, thereby improving its scope of application;

[0055] Secondly, through the structural setting of the support assembly 130, when the scaffold 210 is in use, if relative displacement occurs between two adjacent scaffold steel pipes 211, and the relative displacement will cause certain safety risks, the support assembly 130 can drive the movable pipe 120 to extend into or out of the main pipe body 110, thereby adjusting the overall length of the scaffold monitoring device 100, and then the relative displacement between the two scaffold steel pipes 211 can be compensated, so as to maintain the normal construction state of the scaffold 210, and then it can play the role of temporary transition support to deal with special situations, thereby improving the stability of the scaffold 210, and the ability of the scaffold 210 to deal with the risks of deformation and displacement, thereby improving the safety of the scaffold 210;

[0056] In summary, the scaffolding monitoring device 100 is applied to the scaffolding support system 200, which can monitor the displacement and force of the scaffolding 210, and in the process of monitoring, form or improve the supporting effect of the scaffolding 210, thereby improving the use stability of the scaffolding 210, and further reducing the risk of safety accidents such as collapse or overturning of the scaffolding 210.

[0057] Therefore, the scaffolding support system 200 can use the scaffolding monitoring device 100 to install the outer sleeve of the monitoring alarm device on the guying and wall connecting parts of the scaffolding 210 through the scaffolding steel pipe 211 or other structural methods after the scaffolding 210 is erected. Therefore, when the scaffolding 210 is working, if the scaffolding 210 is overloaded, the scaffolding steel pipe 211 is broken and deformed, or it is tilted or deformed due to foundation settlement, the working status data of the monitor can be monitored in real time, and an alarm can be issued based on the risk situation to remind the construction personnel, thereby realizing accurate real-time monitoring of the scaffolding 210, effectively improving the monitoring effect of the scaffolding 210, and ensuring the safety of the construction personnel during construction.

[0058] It should be noted that, in special scaffolding 210 for hanging, lifting, hanging, plugging, stacking, etc. without a guy support, or scaffolding 210 in a tower where a guy support cannot be set, the scaffolding monitoring device 100 can be connected to the wall connecting parts. When the wall connecting parts are subjected to tension or pressure, the force is also transmitted to the scaffolding monitoring device 100, so that it can achieve the above-mentioned monitoring function and send out an alarm to remind the construction personnel, so as to accurately monitor the scaffolding 210 in real time.

[0059] For further information, please refer to Figure 1-Figure 3 In this embodiment, when configuring the monitoring component 140, in order to enable it to monitor the displacement of the movable tube 120 relative to the main tube 110, the monitoring component 140 includes a sliding rheostat 141, the main body of the sliding rheostat 141 is configured in the main tube 110, and its movable measuring end is connected to the movable tube 120 for monitoring the displacement of the movable tube 120 relative to the main tube 110.

[0060] In order to enable the monitoring component 140 to monitor the pressure of the movable tube 120 used to support the component 130, that is, to monitor the force between two adjacent scaffolding steel pipes 211, the monitoring component 140 also includes a pressure sensor 142. The pressure sensor 142 is arranged between the contact surface of the movable tube 120 and the supporting component 130, and is used to monitor the pressure of the movable tube 120 acting on the supporting component 130.

[0061] It can be seen from the above content that through the setting of the above-mentioned sliding rheostat 141 and pressure sensor 142, it is possible to monitor the displacement between the scaffolding steel pipes 211 at the monitoring position of the scaffolding 210, and also to monitor the corresponding force between the scaffolding steel pipes 211, so that construction personnel can obtain the real-time displacement and pressure data of the position in time, and when multiple monitoring positions are planned and each monitoring position is equipped with a scaffolding monitoring device 100, the construction personnel can fully understand the overall working status of the scaffolding 210, so that they can effectively evaluate the safety risks of the scaffolding 210, thereby improving the safety of construction operations.

[0062] For further information, please refer to Figure 1-Figure 4 In this embodiment, in order to improve the stability of the movable tube 120 when sliding relative to the main body 110, a guide block 121 is disposed at one end of the movable tube 120 located in the main body 110, and the guide block 121 is slidably matched with the main body 110 along the axial direction of the main body 110. Such a configuration can guide the movable tube 120 to move along the axial direction of the main body 110, and based on the configuration of the guide block 121, a boss can be disposed at the tube opening of one end of the main body 110 facing the movable tube 120, so that the movement of the movable tube 120 extending out of the main body 110 is limited by the abutment between the boss and the guide block 121.

[0063] From the above content, please refer to Figure 1-Figure 6 In this embodiment, by configuring the support assembly 130, the movable tube 120 can be supported, and the movable tube 120 can be driven to move along the axis of the main body 110 by the support assembly 130, so that the length of the connecting member formed by the movable tube 120 and the main body 110 can be adjusted to meet the connection requirements at different installation positions, and then when the spacing between two adjacent scaffolding steel pipes 211 changes, the movable tube 120 can be driven to extend into or out of the main body 110 by the support assembly 130, so as to adjust the overall length of the scaffolding monitoring device 100, thereby improving its scope of application; it can also be configured to support the movable tube 120 along the axis of the main body 110 by the support assembly 130, so as to improve the scope of application; When relative displacement occurs between two adjacent scaffolding steel pipes 211 and the relative displacement may cause certain safety risks, the support assembly 130 drives the movable pipe 120 to extend into or out of the main pipe body 110, thereby adjusting the overall length of the scaffolding monitoring device 100, thereby being able to compensate for the relative displacement between the two scaffolding steel pipes 211, thereby maintaining the normal erection state of the scaffolding 210, and thereby being able to play the role of temporary transition support to cope with special situations, thereby being able to improve the stability of the scaffolding 210, and the ability of the scaffolding 210 to cope with the risks of deformation and displacement, thereby being able to improve the safety of the scaffolding 210;

[0064] Based on this, the support assembly 130 includes a support cylinder 131, which is disposed in the main body 110, and the movable end of the piston rod 132 of the support cylinder 131 abuts against one end of the movable tube 120 located in the main body 110. The support cylinder 131 can drive the movable tube 120 to move relative to the axis of the main body 110, thereby driving the movable tube 120 to extend into or out of the main body 110, thereby adjusting the overall length of the scaffold monitoring device 100, thereby improving its scope of application, or compensating for the relative displacement between the two scaffold steel pipes 211, thereby maintaining the normal construction state of the scaffold 210, and then playing the role of temporary transition support to deal with special situations, thereby improving the stability of the scaffold 210, and the ability of the scaffold 210 to deal with the risks of deformation and displacement, thereby improving the safety of the scaffold 210.

[0065] It should be noted that when configuring the above-mentioned supporting cylinder body 131, it can adopt a structural setting mode of a hydraulic cylinder or a pneumatic cylinder.

[0066] Please refer to Figure 1-Figure 6 On the basis of the structure of the above-mentioned support assembly 130, in order to cope with emergencies, for example, when the supporting function of the support cylinder 131 fails due to excessive force between the scaffolding steel pipes 211, in order to avoid the support function disappearing due to the failure of the support cylinder 131, thereby causing the resistance of the movable pipe 120 to move toward the support cylinder 131 to disappear, thereby causing a large displacement between the scaffolding steel pipe 211 connected to the movable pipe 120 and the scaffolding steel pipe 211 connected to the main body 110, thereby causing the scaffolding 210 to have a safety risk, therefore, a limit ring 150 is arranged in the main body 110, and its function is to limit the travel of the movable pipe 120 in the direction of the support cylinder 131, that is, to limit the maximum length of the movable pipe 120 extending into the main body 110, so that in this way, it can play a role in limiting the maximum displacement between two adjacent scaffolding steel pipes 211, thereby improving the stability and safety of the scaffolding 210;

[0067] It should be noted that, under different structural conditions, and in the above content, the force of the movable tube 120 acting on the supporting assembly 130 can be monitored, so that the limit ring 150 can make real-time adjustments to the maximum stroke of the movable tube 120 extending into the main body 110, for example: when the force of the movable tube 120 acting on the supporting assembly 130 is large, the maximum stroke of the movable tube 120 extending into the main body 110 is reduced; when the force of the movable tube 120 acting on the supporting assembly 130 is small, the maximum stroke of the movable tube 120 extending into the main body 110 is increased; and during the adjustment or installation process, in order to adapt to the installation requirements of the scaffolding steel pipes 211 with different intervals, the maximum stroke of the movable tube 120 extending into the main body 110 is increased;

[0068] Based on this, please refer to Figure 1-Figure 6 In order to enable the limiting ring 150 to adjust the maximum stroke of the movable tube 120 extending into the main body 110 in real time, that is, to adjust the position of the limiting ring 150 in the main body 110, the scaffold monitoring device 100 further includes a driving unit 160, the limiting ring 150 is arranged in the main body 110, and is threadedly connected to the main body 110; the limiting ring 150 is sleeved on the piston rod 132;

[0069] The driving unit 160 is connected to the piston rod 132, and the driving unit 160 is used to drive the limiting ring 150 to rotate around the axis of the main body 110, so that the limiting ring 150 moves along the axis direction of the main body 110;

[0070] The limiting ring 150 is used to abut against the guide block 121 to limit the movement of the guide block 121 toward the supporting assembly 130 .

[0071] Therefore, in this way, the limit ring 150 can be driven to rotate around the axis of the main body 110 by the driving unit 160, and a threaded segment 111 is arranged in the main body 110, and the limit ring 150 is threadedly connected with the threaded segment 111 in the main body 110. Therefore, during its rotation, the limit ring 150 can move along the axial direction of the main body 110, and then when the position of the limit ring 150 changes, the maximum stroke of the movable tube 120 extending into the main body 110 can be adjusted in real time.

[0072] When configuring the above-mentioned drive unit 160, please refer to Figure 1-Figure 6 , since the support assembly 130 in this embodiment needs to drive the movable tube 120 to move according to the demand; therefore, the driving unit 160 may include a hollow shaft motor 161 and a rotating sleeve 162;

[0073] The hollow shaft motor 161 is connected to the piston rod 132, the rotating sleeve 162 is sleeved on the piston rod 132, the limiting ring 150 is slidably matched with the limiting ring 150 along the axial direction of the main body 110, and the rotating sleeve 162 is transmission-connected to the hollow shaft motor 161 and the limiting ring 150;

[0074] The hollow shaft motor 161 is used to drive the rotating sleeve 162 to rotate relative to the piston rod 132 , thereby driving the limit ring 150 to rotate relative to the main body 110 , so that the limit ring 150 moves along the axial direction of the main body 110 .

[0075] Therefore, through such a setting, the hollow shaft motor 161 can be mounted on the piston rod 132 through the structure to save installation space, so that it can be arranged in the main body 110 together with the supporting cylinder body 131; secondly, since the rotating sleeve 162 is sleeved on the piston rod 132, and the limiting ring 150 is slidably matched with the limiting ring 150 along the axial direction of the main body 110, therefore, in the process of the piston rod 132 moving to drive the movable tube 120 to move, the hollow shaft motor 161, the rotating sleeve 162 and the piston rod 132 can be synchronized. Movement, and relative sliding between the rotating sleeve 162 and the limiting ring 150, thereby avoiding the movement interference between the rotating sleeve 162 and the limiting ring 150; in addition, in order to enable the rotating sleeve 162 to drive the limiting ring 150 to rotate in the main body 110, and also to be slidably matched with the limiting ring 150, the inner side of the rotating sleeve 162 can be made into a cylindrical surface, and at least one transmission plane is arranged on its outer periphery, and the outer peripheral surface of the rotating sleeve 162 can also be configured as a non-cylindrical surface structure, for example, it can be configured as a structure with a quadrilateral or hexagonal cross-section.
