Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a real-time monitoring system for the verticality of a tower crane. Background Art

[0002] In the current construction industry, tower cranes have become indispensable equipment due to their high efficiency and large load vertical transportation capabilities, playing a vital role in improving construction efficiency and promoting project progress. However, the safety management of tower cranes, especially the precise control of their verticality, has always been a major challenge in construction safety management. Verticality deviation not only affects the stability and operating efficiency of tower cranes, but is also directly related to the safety of personnel and property on the construction site. Any accidents caused by poor verticality monitoring may have serious consequences.

[0003] Traditional tower crane verticality monitoring methods rely on professionals using high-precision measuring instruments such as total stations and theodolites to conduct periodic on-site inspections. This method has many limitations: first, the monitoring results are significantly affected by the technical level and experience of the monitoring personnel, and different personnel operations may lead to inconsistent measurement results; second, the selection of monitoring locations is limited by on-site conditions, and complex or restricted construction environments (such as tower cranes being blocked by buildings) often make it difficult to reach certain key locations, making it impossible to conduct comprehensive and accurate monitoring; third, manual monitoring requires good line of sight and sufficient working space, which is extremely difficult for tower cranes located in densely populated buildings. The selection of monitoring points and the implementation of monitoring work are even impossible in some cases.

[0004] Therefore, how to provide a real-time monitoring system for the verticality of a tower crane to achieve real-time and continuous monitoring of the verticality of a tower crane, ensure the accuracy of the monitoring data, and reduce the risk of safety accidents is a technical problem that technical personnel in this field currently need to solve.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figure 1The present application provides a real-time monitoring system for the verticality of a tower crane, comprising a first clamping plate 1 and a second clamping plate 2, wherein the first clamping plate 1 is detachably connected to an upper tower crane standard section, and the second clamping plate 2 is detachably connected to a lower tower crane standard section adjacent to the upper tower crane standard section; a bending sensor 3, one end of which is detachably connected to the first clamping plate 1, and the other end of which is detachably connected to the second clamping plate 2, for real-time detection and transmission of deformation values; a controller 4, which establishes a signal connection with the bending sensor 3, for receiving and processing the deformation values ​​transmitted by the bending sensor 3; an early warning device, which establishes a signal connection with the controller 4, so as to give an alarm when receiving an early warning signal from the controller 4.

[0028] That is to say, the first clamping plate 1 and the second clamping plate 2 are both detachably installed at the upper and lower ends of the tower crane standard section, wherein the first clamping plate 1 is positioned at the upper tower crane standard section, and the second clamping plate 2 is installed at the lower tower crane standard section directly adjacent thereto, and thus is located at the standard section connection position. One end of the bending sensor 3 is firmly connected to the first clamping plate 1, and the other end is connected to the second clamping plate 2, forming a monitoring bridge across the tower crane standard section connection. The bending sensor 3 can then capture and transmit in real time the vertical deformation value of the tower crane caused by load changes or external factors during operation, providing accurate raw data input for subsequent data analysis.

[0029] A controller 4 is also provided, and is connected to the bending sensor 3 through a signal line, and is responsible for receiving and efficiently processing the deformation data transmitted by the bending sensor 3. The controller 4 can quickly calculate the real-time verticality deviation of the tower crane through a built-in algorithm, and determine whether it exceeds the safety threshold. Once the monitoring data shows that the verticality of the tower crane deviates from the safe range, the controller immediately activates the early warning mechanism and sends a signal to the early warning device. The early warning device, as the response terminal of the system, immediately activates the sound and light alarm after receiving the early warning signal sent by the controller 4, ensuring that the on-site operators can immediately perceive the potential safety risks, take necessary measures in time, and effectively prevent accidents.

[0030] To sum up, the real-time monitoring system for the verticality of a tower crane of the present application realizes accurate and real-time monitoring of the verticality of the tower crane, effectively solves the limitations of traditional manual monitoring, greatly improves the level of construction safety management, and provides a strong safety guarantee for modern construction.

[0031] More specifically, each standard section connection of the tower crane is equipped with a real-time monitoring system for the verticality of the tower crane. Maintenance personnel can focus on checking whether the bolts at the standard section connection are loose based on the early warning points.

[0032] That is to say, by deploying the monitoring system at each standard joint connection, once the verticality of a certain connection deviates from the preset safety range, the warning will respond immediately and indicate the specific warning point. After receiving the warning signal, the maintenance personnel can conduct a detailed inspection of the corresponding standard joint connection, paying special attention to the bolt connection near the warning point, and checking whether there are loose bolts, wear or other forms of connection failure.

[0033] Based on the above embodiment, the first splint 1 and the second splint 2 are both provided with grooves in the length direction, and the grooves are used to engage with the columns of the standard section of the tower crane. The first splint 1 and the second splint 2 are both fixed to the standard section of the tower crane through a connecting member 5, and the connecting member 5 is a bolt. The first splint 1 and the second splint 2 are both provided with mounting holes 6 connecting the grooves.

[0034] That is to say, the first clamping plate 1 and the second clamping plate 2 are provided with grooves in the length direction, and the grooves can fit tightly with the columns of the tower crane standard section, and the connecting parts 5, such as high-strength bolts, are used to achieve a firm connection between the first clamping plate 1 and the second clamping plate 2 and the tower crane standard section. The first clamping plate 1 and the second clamping plate 2 are each preset with mounting holes 6 at positions corresponding to the grooves, and are communicated with the inside of the grooves. During installation, the operator first passes the bolts through the mounting holes 6, and then aligns them with the matching threaded holes on the tower crane standard section, and gradually tightens the bolts with tools such as wrenches until the specified torque value is reached, thereby achieving a firm connection between the first clamping plate 1 and the second clamping plate 2 and the tower crane standard section.

[0035] In another embodiment, in order to further enhance the connection strength and durability between the first clamping plate 1 and the second clamping plate 2 and the tower crane standard section, the first clamping plate 1 and the second clamping plate 2 may be fixed at a designated position by welding.

[0036] On the basis of the above-mentioned embodiment, the same side end surfaces of the first clamping plate 1 and the second clamping plate 2 are both provided with a connecting plate 7 , and the connecting plate 7 is both provided with an installation channel for installing the bending sensor 3 .

[0037] Specifically, in order to facilitate the installation and fixation of the bending sensor 3, connecting plates 7 are added to the same side end faces of the first clamp plate 1 and the second clamp plate 2. Each has a preset special installation channel and is specially designed for the embedding and fixation of the bending sensor 3. It is also easy to maintain and adjust during long-term use, ensuring the continuous and effective operation of the monitoring system.

[0038] The present application uses a locking member 8 to further reinforce the position of the bending sensor 3 on the connecting plate 7. Specifically, the locking member 8 is a locking bolt, and the connecting plate 7 is pre-processed with a threaded hole 9 that communicates with the installation channel. In this way, after the bending sensor 3 is installed in the installation channel of the connecting plate 7, the locking bolt 8 can be easily passed through the threaded hole 9, and tightened to a suitable torque using a tool to achieve a firm locking of the bending sensor 3.

[0039] Based on the above embodiment, the controller 4 further includes a wireless communication unit for wirelessly transmitting the processed deformation value to the terminal display device.

[0040] That is to say, in order to realize the real-time remote access and management of the monitoring data, the controller 4 integrates an advanced wireless communication unit, so that after processing the deformation value transmitted by the bending sensor 3, the controller can instantly transmit these data to the remote terminal display device, such as the computer, tablet computer or smart phone in the construction site monitoring room, through wireless communication technology (such as Wi-Fi, Bluetooth or dedicated wireless communication protocol).

[0041] The wireless transmission function greatly improves the flexibility and efficiency of the tower crane verticality monitoring system. On-site managers or safety supervisors can view the verticality status of each tower crane in real time in the monitoring center or through handheld devices without having to visit the tower crane in person, obtain early warning information in a timely manner, and respond quickly to abnormal situations.

[0042] Based on the above embodiment, the early warning device includes an audible and visual alarm device, which is used to issue a sound and / or light alarm when receiving a warning signal from the controller 4. The early warning device of the present application can be set in the terminal display device or can be set separately.

[0043] That is to say, when the sound and light alarm device is directly built into the terminal display device, this means that when the controller 4 recognizes that the verticality of the tower crane is abnormal and issues a warning signal, the terminal display device will automatically start the built-in sound and light alarm device at the moment of receiving the warning signal, that is, display a striking visual warning sign on the screen, such as a flashing red light or a specific warning icon, and at the same time, the speaker of the device will emit a clear and audible alarm sound, which improves the compactness and response speed of the system.

[0044] Based on the above embodiment, a power supply module is further included to provide a stable working power supply for the bending sensor 3, the controller 4 and the early warning device. The working power supply includes but is not limited to a DC power supply, a battery pack or a solar power supply system.

[0045] On the basis of the above embodiment, the controller 4 also includes a storage unit for storing historical deformation values ​​and / or warning records, so that the controller 4 is not only responsible for processing real-time monitoring data and triggering warnings, but also has a built-in storage unit to automatically record all deformation data received from the bending sensor 3. These data are stored in order in time series to provide data support for the long-term health monitoring of the tower crane structure. By analyzing the historical deformation values, we can gain insight into the stability of the tower crane over time and the potential structural fatigue trend, providing a scientific basis for preventive maintenance. The date, time, verticality deviation value, and environmental conditions of each warning are recorded in detail. This record is of great value for evaluating the effectiveness of the warning system, analyzing the specific reasons for the triggering of the warning, and optimizing the setting of the warning threshold. In addition, the warning record can also serve as an important reference for safety audits and accident investigations.

[0046] In addition, the storage unit supports data backup function, ensuring that historical data can be retained even when the system suffers accidental damage or needs hardware replacement, facilitating subsequent data recovery and analysis. The data stored in the controller can be shared with remote terminal devices through the wireless communication unit, allowing managers to review historical data, conduct remote monitoring and analysis, and improve management efficiency when they are away from the site.

[0047] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
