[0002] As an indispensable large-scale lifting equipment in modern construction, the safety and stability of tower cranes are directly related to the safety and efficiency of the entire construction process. In the use of tower cranes, verticality is a crucial parameter, which directly reflects the stability and accuracy of tower cranes in the vertical direction. The verticality deviation of tower cranes will not only affect the accuracy and efficiency of their lifting operations, but may also cause serious safety accidents, such as collapse and overturning of tower cranes, which directly determines the safety of tower crane operations.

[0003] Traditional tower crane verticality monitoring methods mainly rely on manual measurement and observation, such as regular inspections using tools such as theodolites and plumb lines. These methods are not only time-consuming and labor-intensive, but also difficult to ensure measurement accuracy and real-time performance, and cannot meet the high requirements of modern construction for tower crane safety monitoring. Summary of the invention

[0004] In order to help solve the problems of time-consuming, labor-intensive and low-measurement accuracy of traditional tower crane verticality monitoring methods, the present application provides a tower crane verticality monitoring system and method.

[0005] In a first aspect, the present application provides a tower crane verticality monitoring system, which adopts the following technical solution; A tower crane verticality monitoring system, wherein the monitoring system comprises: A data acquisition module, wherein the data acquisition module comprises a verticality-related data acquisition device installed on the tower crane, and the verticality-related data acquisition device is used to acquire and transmit verticality-related data of the tower crane; A data processing module is used to calculate the verticality according to the verticality related data.

[0006] By adopting the above technical solution, a tower crane verticality monitoring system is proposed. The system obtains the verticality-related data of the tower crane in real time through the data acquisition module and transmits it to the data processing module for calculation. This design makes the verticality monitoring more real-time and accurate, effectively overcomes the limitations of traditional manual measurement methods, and improves the safety and efficiency of tower crane use.

[0007] Preferably, the monitoring system further comprises an alarm module, and the alarm module is used to determine whether to alarm according to the verticality-related data and the verticality.

[0008] By adopting the above technical solution, an alarm module is added. This module can automatically determine whether to trigger an alarm based on the verticality data and calculation results. Once it is found that the verticality exceeds the safe range, an alarm will be immediately issued in the form of voice to remind the operator to pay attention. This function greatly enhances the intelligence and automation level of the system and effectively avoids safety accidents caused by excessive verticality deviation.

[0009] Preferably, the monitoring system further comprises an energy module, wherein the energy module is connected to the data acquisition module and the alarm module, wherein a solar cell panel is arranged inside the energy module, and the solar cell panel is used to supply power to the data acquisition module and the alarm module.

[0010] By adopting the above technical solution, it is proposed to add an energy module to the monitoring system and build in solar panels as a power source, making the system more environmentally friendly and energy-saving, and able to continue working in situations without external power supply, thereby enhancing the applicability and reliability of the system.

[0011] Preferably, the verticality-related data acquisition device includes a wind speed sensor and a weight sensor, the verticality-related data includes the wind speed in the operating area of ​​the tower crane and the load weight of the tower crane, and when the tower crane is unloaded and the wind speed is less than or equal to a preset wind speed threshold, if the verticality is greater than the preset verticality threshold, the alarm module will sound an alarm.

[0012] By adopting the above technical solution, the types of verticality-related data acquisition devices are expanded, and wind speed sensors and weight sensors are added. These two sensors can monitor the wind speed in the tower crane operating area and the load weight of the tower crane in real time, thereby comprehensively considering the impact of the external environment and internal working conditions on verticality. When the tower crane is unloaded and the wind speed exceeds the preset threshold, if the verticality is also out of range, the system will automatically alarm, effectively preventing tower crane instability accidents caused by strong winds.

[0013] Preferably, the verticality-related data acquisition device comprises an inclination sensor, and the inclination sensor is installed on the standard section and / or the attachment frame of the tower crane, and the verticality-related data comprises the inclination angle of the tower crane.

[0014] By adopting the above technical solution, by installing inclination sensors on the standard section and / or attachment frame of the tower crane, these positions can accurately reflect the slight inclination changes of the tower crane in the vertical direction. The inclination sensor can directly measure the inclination angle of the tower crane, which serves as an important basis for verticality calculation. This design improves the accuracy and real-time performance of verticality measurement, and helps to more accurately evaluate the stability of the tower crane.

[0015] Preferably, the verticality-related data acquisition device comprises a displacement sensor, and the displacement sensor is installed on the standard section and / or the attachment frame of the tower crane, and the verticality-related data comprises a horizontal displacement change of the tower crane.

[0016] By adopting the above technical solution, it is further proposed to install a displacement sensor in the system. The sensor can monitor the horizontal displacement change of the tower crane in real time, and together with the inclination sensor, it constitutes a complete verticality monitoring system. This design not only enriches the dimension of monitoring data, but also improves the accuracy and reliability of verticality calculation.

[0017] Preferably, the monitoring system further comprises a voice reminder module, which is located in the cab of the tower crane and is used to remind the driver to turn on the monitoring system according to a preset period.

[0018] By adopting the above technical solution, this timed reminder mechanism helps to ensure that the driver will not forget to start the monitoring system due to negligence, thereby ensuring the periodicity of verticality measurement and reducing downtime and maintenance costs caused by system failure or failure to discover hidden dangers in time. This has positive significance for improving construction efficiency on the construction site and reducing overall operating costs. In addition, the voice reminder module uses voice to remind, which is more intuitive and easier to accept than traditional visual or tactile reminders. This design reflects the humane care for the driver and improves the user experience.

[0019] In a second aspect, the present application provides a tower crane verticality monitoring method, which adopts the following technical solution: A method for monitoring the verticality of a tower crane, wherein the monitoring method comprises: The tilt angle of the tower crane is collected by a tilt sensor, and the horizontal displacement change of the tower crane is collected by a displacement sensor; The verticality is calculated according to the tilt angle and the horizontal displacement change.

[0020] By adopting the above technical scheme, a tower crane verticality monitoring method based on inclination sensor and displacement sensor is described. This method collects the inclination angle and horizontal displacement change data of the tower crane in real time, and uses advanced algorithms and models for accurate calculation and analysis, so as to obtain the real-time verticality status of the tower crane. This method is not only simple to operate and easy to implement, but also can realize real-time and accurate monitoring of the verticality of the tower crane. At the same time, this method also has strong flexibility and scalability, and can be customized and optimized according to different monitoring needs and scenarios. This design principle not only improves the efficiency and accuracy of verticality monitoring, but also provides a strong technical guarantee for the safe and efficient operation of tower cranes.

[0021] Preferably, the monitoring method further comprises: The wind speed in the operation area of ​​the tower crane is collected by a wind speed sensor, and the load weight of the tower crane is collected by a weight sensor; When the tower crane is unloaded and the wind speed is less than or equal to a preset wind speed threshold, an alarm will be issued if the verticality is greater than a preset verticality threshold.

[0022] By adopting the above technical solution, the monitoring logic of wind speed and load weight is further introduced. This design enables the system to comprehensively consider the impact of external environment and internal working conditions on the verticality of the tower crane, so as to make a more accurate and comprehensive judgment. When the tower crane is in an unloaded state and the wind speed is less than or equal to the preset wind speed threshold, the system will conduct a comprehensive evaluation based on the verticality data and issue an alarm when necessary.

[0023] In summary, the tower crane verticality monitoring system and monitoring method proposed in this application realize real-time, accurate monitoring and intelligent early warning of the verticality of the tower crane by integrating multiple sensors and advanced data processing technologies.

[0026] With reference to the accompanying drawings and specific embodiments, the composition, features and advantages of a tower crane verticality monitoring system and method according to the present application will be described below in an exemplary manner. However, all descriptions should not be used to form any limitations on the present application.

[0027] In addition, for any single technical feature described or implied in the embodiments mentioned in this document, or any single technical feature displayed or implied in the accompanying drawings, this application still allows for continued arbitrary combination or deletion between these technical features (or their equivalents) without any technical obstacles, and thus it should be considered that these more embodiments according to this application are also within the scope of the description of this document.

[0028] It should also be noted that the terms "disposed" and the like should be understood in a broad sense, for example, it can be fixedly connected, detachably connected, or integrated; it can be directly connected, or indirectly connected through an intermediate medium. Unless otherwise clearly defined, those skilled in the art can understand the specific meanings of the above terms in this application according to specific circumstances.

[0029] In the prior art, the plumb line laying method is the simplest method for measuring the verticality of tower cranes. Its basic principle is to use the effect of gravity, select an appropriate position at the highest point of the tower body, and place the plumb line directly on the top surface of the foundation of the tower crane. Then, the distance from the highest point and the top surface of the foundation to the same reference plane of the tower body is measured respectively. The difference between the two represents the verticality deviation in this direction. Although the principle is simple, the application of this method has great limitations. It requires an unobstructed passage from top to bottom inside the tower body to ensure that the plumb line can sag naturally under the action of gravity. However, since there are often rest platforms, straight ladders or inclined ladders, tower crane attachment devices and working platforms inside the tower body, it is difficult to find a suitable laying position. In addition, this method requires manual laying and measurement. When the tower crane is high, the laying process takes a long time, the measurement efficiency is low, and the operator faces certain operating risks. It requires multiple people to work together, and the measurement results may also have large errors.

[0030] Figure 1The schematic diagram of the principle of measuring the verticality of a tower crane with a theodolite in the prior art. The theodolite is the most commonly used tool for measuring the verticality of a tower crane. When using the theodolite for measurement, it needs to be set up at a distance of 1.5 times the height of the tower crane, and ensure that the line connecting the theodolite observation point and the tower measurement point is perpendicular to the tower body. Figure 1 As shown in the figure, when measuring the verticality of the tower crane in the AA direction, the tower crane's boom and theodolite should be located in the BB direction. After the theodolite is set up in a suitable position and leveled, a reference point is selected at the top or bottom of the tower body, and the zero point of the steel ruler is aligned at the corresponding position at the other end and set horizontally close to the tower body. The reading projected by the theodolite on the steel ruler is the verticality deviation of the tower crane in this direction.

[0031] Although the theodolite measurement method is more convenient to operate than the plumb line method, it does not require operators to climb up the tower crane, and the measurement error is relatively small. However, this method has clear requirements for the installation position of the theodolite. If it is too close or too far, the instrument is not easy to observe, and it must be installed in front of the tower body, otherwise the measurement result will be affected by the overturning moment of the tower crane itself, and there will be a large error. This limitation of the installation position is difficult to meet in many projects; in addition, after measuring the verticality of the tower crane in one direction, the theodolite needs to be shifted and leveled, and the posture of the tower crane needs to be adjusted to measure the verticality of the tower crane in another direction, which also has the disadvantage of low measurement efficiency.

[0032] Figure 2 The diagram below is a schematic diagram of the measurement direction of the verticality of a tower crane. The degree of deviation of the tower axis relative to the foundation surface is the verticality of the tower crane. When measuring verticality, the tower should be unloaded and the boom should be measured along the boom direction when it is 0° and 90° relative to the tower. The scale should be placed against the lowest and highest points of the center of the tower structure, and the values ​​at the two points should be read. The lateral verticality is calculated as follows: Where: ΔL——lateral verticality; L 1 ——The scale reading of the upper measuring point, in millimeters (mm); L 2 ——The scale reading of the upper measuring point, in millimeters (mm); ΔH – height difference between two measuring points, in millimeters (mm); It can be seen that the verticality of the tower crane needs to be measured without the influence of its own overturning moment and external load, and measured from 0° and 90° along the boom direction. In order to ensure the safe use of the tower crane, the verticality of the tower crane needs to be measured after the first installation of the tower crane, each lifting section of the tower crane, and during the acceptance inspection and regular inspection of the tower crane.

[0033] Figure 3 FIG. 1 is a schematic block diagram of an embodiment of a tower crane verticality monitoring system of the present application. Figure 3 It can be seen that the monitoring system may include a data acquisition module 2, a data processing module 3, an alarm module 4, a voice reminder module 5 and an energy module 1. The data acquisition module 2, the data processing module 3, the voice reminder module 5 and the alarm module 4 are connected in sequence, the data acquisition module 2 includes a verticality-related data acquisition device installed on the tower crane, the verticality-related data acquisition device is used to collect and transmit the verticality-related data of the tower crane, and the data processing module 3 is used to calculate the verticality according to the verticality-related data. In this embodiment, the verticality-related data acquisition device may include an inclination sensor, a position sensor, a wind speed sensor and a weight sensor, and the verticality-related data may include the wind speed in the tower crane operating area, the load weight of the tower crane, the inclination angle of the tower crane and the horizontal displacement change of the tower crane.

[0034] Specifically, the alarm module 4 is used to determine whether to alarm according to the verticality-related data and the verticality. The inclination sensor and position sensor in the data acquisition module 2 respectively detect the inclination angle and horizontal displacement change of the tower crane and transmit them to the data processing module 3. The data processing module 3 calculates the verticality according to the inclination angle and horizontal displacement change; the wind speed sensor and weight sensor in the data acquisition module 2 respectively detect the wind speed and load weight in the operation area of ​​the tower crane. According to Article 5.2.4 of GB / T 5031-2019 "Tower Crane", when the tower crane is unloaded and the wind speed is not more than 3m / s, the lateral verticality error of the axis of the tower body in the independent state (or the tower body above the highest attachment point in the attached state) is not more than 4‰ (four thousandths), and the verticality error of the axis of the tower body below the highest attachment point is not more than 2‰ (two thousandths). When the tower crane is unloaded and the wind speed is greater than the preset wind speed threshold, if the verticality is greater than the preset verticality threshold, the alarm module 4 will sound an alarm.

[0035] The voice reminder module 5 is located in the cab of the tower crane and is used to remind the driver to turn on the monitoring system according to a preset period. The driver will drive the tower crane to a specified position to measure the verticality of the tower crane. In this embodiment, the preset period can be one day. After the tower crane driver goes to work every day, the voice reminder module 5 located in the cab will automatically remind the driver to turn on the monitoring system to measure the verticality of the tower crane, thereby forming a daily verticality monitoring account for the tower crane.

[0036] This timed reminder mechanism helps ensure that the driver does not forget to start the monitoring system due to negligence, thereby maintaining continuous monitoring of the tower crane's operating status and reducing downtime and maintenance costs caused by system failures or failure to discover hidden dangers in a timely manner. This has a positive significance for improving construction efficiency on the construction site and reducing overall operating costs. In addition, the voice reminder module 5 uses voice to remind, which is more intuitive and easier to accept than traditional visual or tactile reminders. This design reflects the humanistic care for the driver and improves the user experience.

[0037] The energy module 1 is provided with a solar panel 7 and a battery 6. The energy module 1 is connected to the data acquisition module 2 and the alarm module 4. The solar panel 7 is used to power the data acquisition module 2 and the alarm module 4. The energy module 1 uses battery power supply and solar power function to power the data acquisition module 2, the voice reminder module 5 and the alarm module 4.

[0038] Using the battery 6 as an energy storage unit can provide stable power for the sensor. It has the characteristics of small size, but less energy storage and needs to be replaced regularly. Using the solar panel 7 to convert solar energy into electrical energy is suitable for sensors that work outdoors or in remote areas for a long time. Tower cranes are usually the highest units in the coverage area, with sufficient sunlight and no obstruction. Using this method can not only reduce the use and replacement of the battery 6, but also achieve energy saving and environmental protection.

[0039] Figure 4 for Figure 3 The data processing module 3 can be located in a remote host computer, and the data acquisition module can be located at the work site. Figure 4 It can be seen that the monitoring system will control the data acquisition module 2 on site to perform daily routine inspections and random work capture. The data acquisition module 2 will collect the aforementioned physical quantities such as wind speed and load, and calculate the verticality based on the data such as inclination angle and displacement change, and transmit the verticality to the management personnel. The verticality-related data during this period will be stored in the background database, and the verticality data will be archived online.

[0040] Both the inclination sensor and the position sensor can be installed on the standard section and / or attachment frame of the tower crane. By installing the inclination sensor on the standard section and / or attachment frame of the tower crane, these positions can accurately reflect the slight tilt changes of the tower crane in the vertical direction. The inclination sensor can directly measure the inclination angle of the tower crane, which serves as an important basis for verticality calculation. This design improves the accuracy and real-time performance of verticality measurement, and helps to more accurately evaluate the stability of the tower crane. The displacement sensor can monitor the horizontal displacement change of the tower crane in real time, and together with the inclination sensor, it constitutes a complete verticality monitoring system. This design not only enriches the dimension of the monitoring data, but also improves the accuracy and reliability of the verticality calculation. The inclination sensor and the position sensor can be collectively referred to as a verticality detection sensor 8.

[0041] Figure 5 is a structural schematic diagram of an embodiment of a verticality detection sensor fixing device, Figure 6 The verticality detection sensor is installed on a tower crane. Figure 5 and Figure 6 It can be understood that the verticality detection sensor 8 is installed on the verticality detection sensor fixing device, and the verticality detection sensor fixing device may include a fixing plate 9 and a fixing bracket 10. The verticality detection sensor 8 can be installed on the standard section of the tower crane through the fixing plate 9 and the fixing bracket 10. The position of the standard section can accurately reflect the slight tilt changes of the tower crane in the vertical direction and the slight displacement changes in the horizontal direction, thereby improving the accuracy of the detection results.

[0042] Figure 7 FIG. 1 is a flow chart of an embodiment of a tower crane verticality monitoring method of the present application. Figure 7 It can be seen that the monitoring method can include three steps, and each step is described in detail below.

[0043] Step S1: The tilt angle of the tower crane is collected by the tilt sensor, and the horizontal displacement change of the tower crane is collected by the displacement sensor. In step S1, the tilt sensor is a sensor that can measure the tilt angle of an object relative to the horizontal plane. It senses the component of gravity acceleration in the tilt direction through internal sensitive elements and converts it into an electrical signal output. In the tower crane, the tilt sensor is installed at an appropriate position of the tower body to measure the tilt angle of the tower body in real time. The displacement sensor is used to measure the linear change of the position of an object. In the tower crane monitoring system, the displacement sensor may be used to measure the displacement change of the tower body or key components in the horizontal direction to reflect the stability of the tower body. In this way, the tilt angle and horizontal displacement change of the tower crane can be obtained in real time and accurately, providing basic data for subsequent verticality calculation and monitoring. And improve the sensitivity and response speed of the monitoring system to ensure that timely detection and measures can be taken when the tower body is tilted or displaced.

[0044] Step S2: Calculate verticality based on the tilt angle and horizontal displacement change. In step S2, the verticality of the tower is calculated through a specific algorithm based on the data collected by the tilt sensor and the displacement sensor, combined with the geometric structure and mechanical characteristics of the tower crane. Verticality is an important indicator to measure the degree of deviation between the tower axis and the vertical direction, which is crucial to ensure the safe and stable operation of the tower crane.

[0045] The verticality value of the tower body is obtained through accurate calculation, which provides a basis for the judgment of the monitoring system. It can intuitively reflect the stability of the tower body and help operators understand the real-time working conditions of the tower crane.

[0046] Step S3: The wind speed in the tower crane operating area is collected through a wind speed sensor, and the load weight of the tower crane is collected through a weight sensor. When the tower crane is unloaded and the wind speed is less than or equal to the preset wind speed threshold, if the verticality is greater than the preset verticality threshold, an alarm will be issued. In step S3, the wind speed sensor is used to measure the wind speed in the tower crane operating area in real time. Wind speed is one of the important factors affecting the stability of the tower crane. The tower body is prone to tilt or shake under strong wind conditions. The weight sensor is installed on the hook or lifting mechanism of the tower crane to measure the weight of the hanging object. The load weight is also one of the factors affecting the stability of the tower body. Too heavy or too light a load may have an adverse effect on the stability of the tower body.

[0047] When the tower crane is in an unloaded state and the wind speed in the operating area is less than or equal to the preset wind speed threshold, the system will compare the verticality value calculated in step S2 with the preset verticality threshold. If the verticality is greater than the preset verticality threshold, it means that the tower body has deviated from the vertical direction a lot and there is a safety hazard. At this time, the system will issue an alarm. By comprehensively considering the impact of wind speed and load weight on the stability of the tower body, the accuracy and reliability of alarm triggering are improved. When the tower body is seriously tilted or there is a safety hazard, an alarm will be issued in time to remind the operator to take corresponding measures to ensure the safe and stable operation of the tower crane.

[0048] In summary, the design of the monitoring system of this application has the following three significant features: First, wide versatility. The system is suitable for all types of tower cranes, whether it is boom luffing type or trolley luffing type, it can easily cope with it. At the same time, it can also be widely used in various forms of tower cranes, including independent state, attachment form, and internal climbing or external hanging form, showing strong adaptability.

[0049] Second, it is significantly advanced. This system can realize dynamic monitoring of tower cranes and grasp the tilt status of tower cranes in real time by sending special personnel to install and debug tower cranes during installation and each lifting and lowering. It can automatically collect data on the verticality of tower cranes and form a management account, thus greatly saving human resources. At the same time, its high measurement accuracy provides a strong guarantee for the safety management of tower cranes.

[0050] Third, strong promotion. The application scope of this tower crane verticality monitoring system is not limited to the tower crane itself, but can also be easily promoted and applied to the verticality monitoring of construction hoists and tower crane combined foundation steel lattice columns, showing its wide application potential and market value.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
