Description

Technical Field

[0001] This invention relates to the field of tower crane installation technology, specifically to a method and device for monitoring the entire process of tower crane height adjustment. Background Technology

[0002] The raising and lowering of tower cranes is the most dangerous process and the most prone to major accidents. If an accident occurs during the raising or lowering of the tower crane, it usually leads to the collapse and damage of the tower crane, serious injury or even death of the installation and dismantling workers, causing significant economic and personal safety losses, as well as adverse social impacts.

[0003] In tower crane accidents, the vast majority are caused by improper operation by installation and dismantling workers. For example, starting to unload the load before the lifting beam is properly attached to the steps, or starting to push out the hydraulic cylinder before the support rod is firmly planted. Therefore, monitoring and ensuring proper operation at every critical point during tower crane height adjustment can significantly reduce the likelihood of accidents.

[0004] Existing tower crane monitoring systems often only monitor the completion of a few key steps, such as whether the steps are in place or whether the tower is tilted. The lack of oversight of the entire height adjustment process leads to incomplete monitoring information, causing many real risks to be overlooked and undetected. Summary of the Invention

[0005] The purpose of this invention is to provide a method and device for monitoring the entire process of tower crane height adjustment, in order to solve the problem that the existing technology does not monitor the operation sequence of the entire height adjustment process, which leads to incomplete monitoring information and thus overlooks many real risks that are not identified.

[0006] To achieve the above objectives, the first aspect of the present invention provides a method for monitoring the entire process of tower crane height adjustment, comprising:

[0007] In response to the height adjustment command, based on the preset height adjustment standard process, it is determined whether each process of the tower crane has been completed in the height adjustment process.

[0008] Once it is confirmed that the current process is complete, determine whether the next process is complete.

[0009] If it is determined that the current process has not been completed, the pump station of the tower crane is locked to achieve full-process monitoring of the tower crane height adjustment.

[0010] In this embodiment of the invention, the pump station locking of the control tower crane includes:

[0011] Real-time acquisition of tower crane cylinder pressure;

[0012] Determine whether the hydraulic cylinder pressure of the tower crane has reached the preset pressure value corresponding to the current process;

[0013] When it is determined that the hydraulic cylinder pressure of the tower crane has reached the preset pressure value corresponding to the current process, the pump station of the tower crane is locked.

[0014] In this embodiment of the invention, determining whether the process of the tower crane is completed during height adjustment includes:

[0015] Real-time acquisition of images of the corresponding work points during the height adjustment process of the tower crane;

[0016] Based on a preset target detection model, key components in the image of the working point are detected to obtain the working status of the working point.

[0017] Based on the working status of the work point, determine whether the tower crane has completed the work process during the height adjustment process.

[0018] In this embodiment of the invention, determining whether the process of the tower crane is completed during height adjustment includes:

[0019] Real-time acquisition of images of the corresponding work points during the height adjustment process of the tower crane;

[0020] The images of the work points are sent to the monitoring terminal, which then determines whether the tower crane has completed the required procedures during height adjustment.

[0021] In this embodiment of the invention, the images of the corresponding work points during the height adjustment process of the tower crane are captured by cameras installed at the corresponding work points.

[0022] In this embodiment of the invention, the camera is a detachable camera.

[0023] In this embodiment of the invention, the height adjustment is a tower raising mechanism;

[0024] In response to a height adjustment command, based on a preset height adjustment standard procedure, the system sequentially determines whether each step in the height adjustment process has been completed, including:

[0025] In response to the tower lifting command, based on the preset tower lifting standard procedure, it is determined in sequence whether each process of the tower crane has been completed in the tower lifting process.

[0026] In this embodiment of the invention, the height adjustment is a tower lowering mechanism;

[0027] In response to a height adjustment command, based on a preset height adjustment standard procedure, the system sequentially determines whether each step in the height adjustment process has been completed, including:

[0028] In response to the tower lowering command, based on the preset tower lowering standard procedure, it is determined in sequence whether each process of the tower crane has been completed in the tower lowering process.

[0029] In this embodiment of the invention, it further includes:

[0030] Wind power monitoring and / or anomaly monitoring are performed on the tower crane to obtain auxiliary monitoring results.

[0031] A second aspect of the present invention provides a tower crane height adjustment full-process monitoring device, comprising:

[0032] The monitoring module is used to respond to height adjustment commands and, based on a preset height adjustment standard process, sequentially determine whether each process of the tower crane has been completed during the height adjustment process; if the current process has been completed, it determines whether the next process has been completed; if the current process has not been completed, it controls the tower crane's pump station to lock, so as to realize full-process monitoring of the tower crane's height adjustment.

[0033] Through the above technical solution, in response to height adjustment commands and based on a preset height adjustment standard procedure, the system sequentially determines whether each step of the tower crane's height adjustment process is in place. If the current step is confirmed to be in place, the system then checks whether the next step is in place. If the current step is not in place, the system locks the tower crane's pump station, thus achieving full-process monitoring of the tower crane's height adjustment. By sequentially determining whether each step of the height adjustment process is in place, all steps in the height adjustment process can be included in the monitoring. Only when the current step is in place is the next step checked, thus monitoring the entire operational sequence and making the monitoring information more complete. This reduces the risk of overlooking many real risks. If a step is not in place, locking the tower crane's pump station prevents workers from operating the crane and continuing the process, effectively restricting worker operation and preventing tower crane accidents, thereby improving the reliability and accuracy of tower crane height adjustment monitoring. The preset height adjustment standard procedure clarifies the sequential relationship between each step, facilitating the early identification of risky steps. This method can standardize the operating procedures of installation and dismantling workers, provide targeted training, improve worker skills, and help reduce the risk of accidents.

[0047] Figure 1 The illustration schematically shows a process diagram of a tower crane height adjustment end-to-end monitoring method according to an embodiment of the present invention. Figure 1 As shown in the figure, this embodiment of the invention provides a method for monitoring the entire process of tower crane height adjustment, which may include the following steps:

[0048] Step 210: In response to the height adjustment command, based on the preset height adjustment standard process, determine in sequence whether each process of the tower crane has been completed in the height adjustment process;

[0049] In this embodiment, the height adjustment command can be input by the user or automatically triggered by the system after determining that tower crane height adjustment is required. The tower crane height adjustment includes tower crane raising and lowering. The preset height adjustment standard procedure refers to the process steps set according to the standard tower crane raising or lowering process, including all steps in the tower crane raising or lowering process, and can be pre-set. That is, the preset height adjustment standard procedure can include preset tower raising standard procedures and tower lowering standard procedures. The preset height adjustment standard procedure includes multiple process steps, and the worker can be judged in sequence whether the work is completed properly when performing each process step according to the process steps in the preset height adjustment standard procedure. The judgment of whether the tower crane has completed the process steps during height adjustment can be made by using a camera to capture images of key components at the corresponding work point, and then using a pre-trained self-learning algorithm model based on the key component images to judge whether the process is completed properly; alternatively, the captured images can be sent to the supervisor for manual judgment of whether the process is completed properly, and the judgment result can be input into the system.

[0050] It should be noted that the process mentioned in this embodiment refers to the comprehensive production activities of one (or a group of) workers on the components of the tower crane during the tower crane height adjustment, and is the basic unit that constitutes the tower crane height adjustment process.

[0051] In some embodiments, the height adjustment is tower lifting; correspondingly, the step of responding to the height adjustment command and sequentially determining whether each process in the height adjustment process is in place based on a preset height adjustment standard procedure includes: responding to the tower lifting command and sequentially determining whether each process of the tower crane is in place during the tower lifting process based on a preset tower lifting standard procedure.

[0052] In this embodiment, if the current height is adjusted to tower raising, the tower raising process is monitored after receiving the tower raising command. That is, according to the preset tower raising standard process, the tower crane is judged in turn to determine whether each process of the tower crane is in place during the tower raising process, thereby realizing full-process monitoring of the tower crane's tower raising process.

[0053] In some embodiments, the height adjustment is a tower lowering; correspondingly, the step of responding to the height adjustment command and, based on a preset height adjustment standard procedure, sequentially determining whether each step in the height adjustment process has been completed includes: responding to the tower lowering command and, based on a preset tower lowering standard procedure, sequentially determining whether each step in the tower crane has been completed during the tower lowering process.

[0054] In this embodiment, if the current height is adjusted to lower the tower crane, the tower crane will start monitoring the tower crane lowering process after receiving the tower crane lowering command. That is, according to the preset tower crane lowering standard process, the tower crane will be judged in turn to determine whether each process of the tower crane has been completed in the tower crane lowering process, so as to realize full-process monitoring of the tower crane lowering process.

[0055] In some embodiments, determining whether the tower crane has completed the required operation during height adjustment for each process includes the following steps:

[0056] First, images of the corresponding work points of the process during the height adjustment of the tower crane are acquired in real time;

[0057] In this embodiment, the images of the aforementioned work points refer to images of the operational status of the corresponding work points during the tower crane's raising or lowering process, acquired in real time. These images can be obtained by installing a camera at the corresponding location of the work point and capturing the images in real time. In practice, the camera's installation location can be set and adjusted according to actual conditions.

[0058] For example, during the tower crane's lifting process, the first step corresponds to the working point of the lifting cylinder. This can be achieved by installing a camera on the tower crane's crossbeam and reading the image captured by this camera. The next step corresponds to the working point of the upper pin shaft of the standard section. This can also be achieved by installing a camera on the plane of the upper pin shaft and reading the image captured by this camera. The next step corresponds to the working point of the standard section lifting frame. Again, this can be achieved by installing a camera on the plane of the upper pin shaft and reading the image captured by this camera. This image of the standard section lifting frame can be used to determine the engagement of the standard section lifting frame. Alternatively, a camera can be installed on the bottom traveling net of the superstructure. This image of the standard section lifting frame can be used to determine its introduction and retraction. The next step corresponds to the working point of the lower pin shaft of the standard section. This can also be achieved by installing a camera on the bottom traveling net of the superstructure and reading the image captured by this camera. The next step corresponds to the working point of the step-changing support rod. Alternatively, a camera can be installed on the bottom traveling net of the superstructure, and the image of the step-changing support rod can be obtained by reading the footage from the camera installed on the bottom traveling net of the superstructure. The next step corresponds to the working point of the crossbeam safety pin. This can be achieved by installing a camera on the crossbeam of the tower crane, and obtaining the image of the crossbeam safety pin by reading the footage captured by this camera.

[0059] Then, based on the preset target detection model, the key components in the image of the working point are detected to obtain the working status of the working point;

[0060] In this embodiment, the aforementioned preset target detection model can be a pre-trained target detection model used to detect key components in the image of the working point. By detecting the information of the key components, the state of the working point is determined, thereby detecting the current working state of the working point. Different working points may correspond to different key components, which can be determined according to the actual situation.

[0061] Finally, based on the working status of the work points, it is determined whether the tower crane has completed the required procedures during the height adjustment process.

[0062] In this embodiment, after obtaining the working status of the working point, it can be determined whether the working status is the expected working status of the current process. If it is, it means that the current process has been completed; if not, it means that the current process has not been completed.

[0063] By using a pre-set target detection model to detect key components in the image of the working point, the working status of the working point can be quickly and accurately determined. This allows for quick and accurate judgment of whether the tower crane's operations are in place during height adjustment, enabling visual monitoring and identification of all key points during the tower crane's lifting process.

[0064] In some embodiments, determining whether the process of the tower crane is completed during height adjustment includes the following steps:

[0065] First, images of the corresponding work points of the process during the height adjustment of the tower crane are acquired in real time;

[0066] In this embodiment, the images of the aforementioned work points refer to images of the operational status of the corresponding work points during the tower crane's raising or lowering process, acquired in real time. These images can be obtained by installing a camera at the corresponding location of the work point and capturing the images in real time. In practice, the camera's installation location can be set and adjusted according to actual conditions.

[0067] Then, the image of the work point is sent to the monitoring terminal, which determines whether the tower crane has completed the work during the height adjustment process.

[0068] In this embodiment, the aforementioned monitoring terminal can be judged manually. For example, it can be sent to the staff's mobile phone to obtain the work completion status as judged by the staff, so as to determine whether the current process has been completed.

[0069] By sending images of the work points to the monitoring terminal, the monitoring terminal can determine whether the tower crane's operations are completed correctly during the height adjustment process. This makes the judgment accurate and reliable, thereby improving the accuracy and reliability of the entire process monitoring of tower crane height adjustment.

[0070] The above-mentioned methods for determining whether the tower crane has completed its work during height adjustment require images of the work points. In some embodiments, the images of the work points corresponding to the work points during the tower crane height adjustment process are captured by cameras installed at the corresponding work points.

[0071] In this embodiment, cameras can be installed at each corresponding work point in the process, and the specific setup can be flexibly adjusted according to different work points. For example, for the upper pin working point of the standard section, a camera can be installed on the upper pin plane, and the image of the upper pin of the standard section can be obtained by reading the image from the camera installed on the upper pin plane. For the lifting frame working point of the standard section, a camera can also be installed on the upper pin plane, and the image of the lifting frame of the standard section can be obtained by reading the image from the camera installed on the upper pin plane. This image of the lifting frame of the standard section can be used to determine the engagement of the lifting frame of the standard section. A camera can also be installed on the bottom traveling net of the upper structure, and the image of the lifting frame of the standard section can be obtained by reading the image from the camera installed on the bottom traveling net of the upper structure. This image of the lifting frame of the standard section can be used to determine the introduction and withdrawal of the lifting frame of the standard section. For the lower pin working point of the standard section, a camera can also be installed on the bottom traveling net of the upper structure, and the image of the lower pin of the standard section can be obtained by reading the image from the camera installed on the bottom traveling net of the upper structure. For the working point of the step-changing support rod, a camera can be installed on the bottom traveling net of the superstructure, and the image of the step-changing support rod can be obtained by reading the image from the camera installed on the bottom traveling net of the superstructure. For the working point of the crossbeam safety pin, a camera can be installed on the crossbeam of the tower crane, and the image of the crossbeam safety pin can be obtained by reading the image captured by the camera.

[0072] During the height adjustment process of the tower crane, the images of the corresponding work points are captured by cameras installed at the corresponding work points. This allows the images of the work points to effectively reflect the operation status of the corresponding work points, which helps to improve the reliability of judging whether the process has been completed.

[0073] The camera is a detachable camera.

[0074] In this embodiment, the detachable camera can be removed from the device, its position can be adjusted as needed, or it can be used independently. It can be flexibly set according to the operation situation to meet the needs of various scenarios.

[0075] Step 220: If the current process is confirmed to be in place, determine whether the next process is in place;

[0076] In this embodiment, if the current process is completed, it means that the worker is operating correctly in the current process, and the next process can be monitored, that is, the next process can be judged according to the preset height adjustment standard process.

[0077] Step 230: If it is determined that the current process has not been completed, control the tower crane's pump station to lock, so as to realize the full-process monitoring of the tower crane height adjustment.

[0078] In this embodiment, if the current process is not completed, it indicates that the worker has made an error in operating the current process. To prevent tower crane accidents, the tower crane's pump station can be locked. Once locked, the worker will be unable to operate the pump station and will be unable to continue performing the process, thus restricting the worker's operation and effectively preventing tower crane accidents. The aforementioned control of the tower crane's pump station locking can be achieved by directly issuing a locking command or by automatic locking.

[0079] In some embodiments, locking the pump station of the control tower crane includes the following steps:

[0080] First, the hydraulic cylinder pressure of the tower crane is acquired in real time;

[0081] In this embodiment, a pressure sensor can be installed near the pump station, specifically on the oil line leading to the oil cylinder, to collect the oil cylinder pressure in real time.

[0082] Then, it is determined whether the hydraulic cylinder pressure of the tower crane has reached the preset pressure value corresponding to the current process;

[0083] In this embodiment, the preset pressure value can be set in advance according to the actual situation. Different processes can have different pressure values. For example, there are different threshold values ​​for the states of prohibiting cylinder loading and prohibiting cylinder unloading. The current process determines which state is currently in, and thus determines the corresponding pressure value. The above judgment can be made by comparing the cylinder pressure with the preset pressure value corresponding to the current process to determine whether it has been reached.

[0084] Then, after determining that the hydraulic cylinder pressure of the tower crane has reached the preset pressure value corresponding to the current process, the pump station of the tower crane is locked.

[0085] In this embodiment, the aforementioned control of the tower crane's pump station locking can be achieved through an intelligent two-way lock. For example, when the cylinder load is prohibited, the intelligent two-way lock determines whether the cylinder pressure has reached a preset pressure value. If it has, the tower crane's pump station is locked.

[0086] By acquiring the hydraulic cylinder pressure of the tower crane in real time, it can be determined whether the hydraulic cylinder pressure of the tower crane has reached the preset pressure value corresponding to the current process. If it is determined that the hydraulic cylinder pressure of the tower crane has reached the preset pressure value corresponding to the current process, the pump station of the tower crane can be locked, which can control the pump station locking of the tower crane more intelligently.

[0087] In the above implementation process, in response to height adjustment commands, based on a preset height adjustment standard procedure, the system sequentially determines whether each step of the tower crane's height adjustment process is in place. If the current step is confirmed to be in place, the system checks whether the next step is in place. If the current step is not in place, the system locks the tower crane's pump station, thus achieving full-process monitoring of the tower crane's height adjustment. By sequentially determining whether each step of the tower crane's height adjustment process is in place, all steps in the height adjustment process can be included in the monitoring. Only when the current step is in place is the system checked whether the next step is in place, thus allowing for monitoring of the entire process's operational sequence. This makes the monitoring information more complete and reduces the risk of overlooking many real risks. If a step is not in place, locking the tower crane's pump station prevents the worker from operating the crane and continuing the process, effectively restricting worker operation and preventing tower crane accidents, thereby improving the reliability and accuracy of tower crane height adjustment monitoring. The preset height adjustment standard procedure clarifies the sequential relationship between each step, facilitating the early identification of risky steps. This method can standardize the operating procedures of installation and dismantling workers, provide targeted training, improve worker skills, and help reduce the risk of accidents.

[0088] In some embodiments, the method further includes: performing wind power monitoring and / or anomaly monitoring on the tower crane to obtain auxiliary monitoring results.

[0089] In this embodiment, the aforementioned anomaly monitoring includes tower crane balancing monitoring, etc., and the aforementioned wind power monitoring and / or anomaly monitoring can be performed continuously throughout the entire process. The aforementioned wind power monitoring and anomaly monitoring can be implemented using existing technologies, and will not be elaborated further here.

[0090] By monitoring the tower crane for wind and / or abnormalities, auxiliary monitoring results can be obtained, which can further improve the reliability and accuracy of monitoring the tower crane's height adjustment.

[0091] The following sections explain the scheme from the perspectives of the tower crane's lifting and lowering processes. Please refer to [link / reference]. Figure 2 and Figure 3 , Figure 2 This schematic diagram illustrates the tower lifting process of a tower crane according to an embodiment of the present invention; Figure 3 The diagram illustrates the tower crane lowering process according to an embodiment of the present invention.

[0092] It should be noted that, in Figure 2 and Figure 3In the diagram, red text indicates a non-visual judgment step, which can be performed through tower crane operating information or manual worker confirmation. Blue squares indicate that this step only allows cylinder loading or prohibits cylinder unloading; in this state, the weight on the tower crane is borne by the lifting cylinders. White squares indicate that this step only allows cylinder unloading or prohibits cylinder loading; in this state, the weight on the tower crane cannot be borne by the lifting cylinders, but by the tower body or the step-changing support rods. If a negative arrow is not drawn on the diamond-shaped judgment box, the step is re-judged by default.

[0093] Please refer to Figure 2For tower crane lifting, a pre-set standard lifting procedure can be established. During the monitoring of the entire tower crane lifting process, the system first responds to the lifting command. If the tower crane is in a prohibited cylinder load state, it checks whether the tower crane's cylinders have retracted. If the cylinders have retracted, it indicates the current process is complete, and then it checks whether the tower crane's crossbeam pin has been inserted. If the cylinders have not retracted, it indicates the current process is not complete, and the tower crane's pump station can be locked. If the crossbeam pin is inserted, it indicates the current process is complete, and then it checks whether the tower crane's lifting frame has been engaged. If the lifting frame is engaged, it indicates the current process is complete, and then it checks whether the tower crane is in a balanced operating state. If the lifting frame is not engaged, it indicates the current process is not complete, and the tower crane's pump station can be locked. If the tower crane is confirmed to be in the balancing state, check if the upper pin of the tower crane has been pulled out. If the upper pin has been pulled out, it indicates that the current process is complete, and the tower crane's status is adjusted to the prohibited cylinder unloading state, the pump station is activated with high pressure, and it is determined whether the tower crane is undergoing its initial lifting. If the upper pin has not been pulled out, it indicates that the current process is not complete, and the pump station of the tower crane can be locked. If the tower crane is confirmed to be undergoing its initial lifting, check if the lifting function of the tower crane is normal. If the lifting function of the tower crane is normal, check if there is any offset during the installation of the tower crane, i.e., check if the tenon is vertical. If the lifting function of the tower crane is abnormal, it indicates an anomaly, and the process is terminated directly. If the tower crane is not undergoing its initial lifting, check if there is any offset during the installation of the tower crane, i.e., check if the tenon is vertical. If the tenon is confirmed to be vertical, it indicates the current process is complete, and the crane should then check if the hydraulic cylinder has extended. If the tenon is not confirmed to be vertical, it indicates the current process is incomplete, and the crane's pump station should be locked. If the hydraulic cylinder is confirmed to be extended, check if the step has completed its movement. If the step has completed its movement, check if the lifting frame has been introduced. If the step has not completed its movement, check if there is step support. If step support is present, it indicates the current process is complete, and the crane should then check if the crossbeam pin has been pulled out. If there is no step support, it indicates the current process is incomplete, and the crane's pump station should be locked. If the crossbeam pin is confirmed to be pulled out, it indicates the current process is complete, and the crane's status is adjusted to a state where the hydraulic cylinder load is prohibited. The crane should then check if the hydraulic cylinder has retracted. If the crossbeam pin has not been pulled out, it indicates the current process is incomplete, and the crane's pump station should be locked. If the hydraulic cylinder has been confirmed to have retracted, it indicates the current process is complete, and the crane should check if the crossbeam pin has been inserted. If the hydraulic cylinder has not retracted, it indicates the current process is incomplete, and the crane's pump station should be locked.If the crossbeam pin is confirmed to be inserted, it indicates the current process is complete. The tower crane's status is adjusted to the "prohibit cylinder unloading" state, and the crane checks if the cylinder has extended. If the crossbeam pin is not inserted, it indicates the current process is incomplete, and the tower crane's pump station can be locked. If the lifting frame is confirmed to be introduced, it indicates the current process is complete, and the crane checks if the lower pin is inserted. If the lifting frame is not introduced, it indicates the current process is incomplete, and the tower crane's pump station can be locked. If the lower pin is confirmed to be inserted, it indicates the current process is complete, and the crane checks if the lifting frame has retracted. If the lower pin is not inserted, it indicates the current process is incomplete, and the tower crane's pump station can be locked. If the lifting frame has retracted, it indicates the current process is complete, and the crane checks whether to continue jacking (i.e., continue raising the tower). If the lifting frame has not retracted, it indicates the current process is incomplete, and the tower crane's pump station can be locked. The above-mentioned determination of whether to lift can be done manually or by setting a number of lifting attempts. If lifting continues, it checks whether the crossbeam pin has been pulled out; if lifting stops, it checks whether the upper pin has been inserted. If the crossbeam pin is pulled out, it indicates that the current process is complete, the tower crane's status is adjusted to prohibit cylinder load, and the pump station allows low pressure. The process then returns to checking whether the tower crane's cylinder has retracted, and the above steps are repeated. If the crossbeam pin is not pulled out, it indicates that the current process is not complete, and the tower crane's pump station can be locked. If the upper pin is inserted, it indicates that the current process is complete, the tower crane's status is adjusted to prohibit cylinder load, and the pump station allows low pressure. It then checks whether there is no load. If yes, the process ends; otherwise, it indicates that the current process is not complete, and the tower crane's pump station can be locked. If the upper pin is not inserted, it indicates that the current process is not complete, and the tower crane's pump station can be locked.

[0094] Please refer to Figure 3For tower crane lowering, a pre-set standard lowering procedure can be established. During the monitoring of the entire lowering process, upon receiving the lowering command, the tower crane is in a prohibited cylinder load state. The system checks if the cylinder has extended. If it has, the current process is complete, and the system checks if the crossbeam pin has been inserted. If the cylinder has not extended, the current process is incomplete, and the tower crane's pump station can be locked. If the crossbeam pin is inserted, the current process is complete, and the system checks if the lifting frame is engaged. If the crossbeam pin is not engaged, the current process is incomplete, and the tower crane's pump station can be locked. If the lifting frame is engaged, the current process is complete, and the system checks if the tower crane is in a balanced operating state. If the lifting frame is not engaged, the current process is incomplete, and the tower crane's pump station can be locked. If the tower crane is determined to be in a balanced operating condition, check if the upper pin has been removed. If the tower crane is determined to be in an unbalanced operating condition, it indicates that the current process has not been completed, and the tower crane's pump station can be locked. If the upper pin has been removed, it indicates that the current process has been completed. The tower crane's status is adjusted to a state where cylinder unloading is prohibited, the pump station is activated with high pressure, and it is checked whether there is any offset during the tower crane's installation, i.e., whether the tenon is vertical. If the upper pin has not been removed, it indicates that the current process has not been completed, and the tower crane's pump station can be locked. If the tenon is determined to be vertical, it indicates that the current process has been completed, and the lifting frame is checked for insertion. If the tenon is determined to be not vertical, it indicates that the current process has not been completed, and the tower crane's pump station can be locked. If the lifting frame is determined to be inserted, it indicates that the current process has been completed, and the lower pin has been checked for removal. If the lifting frame is determined not to be inserted, it indicates that the current process has not been completed, and the tower crane's pump station can be locked. If the lower pin is confirmed to be removed, it indicates the current process is complete; check if the lifting frame has retracted. If the lower pin is not confirmed to be removed, it indicates the current process is incomplete; in this case, the tower crane's pump station can be locked. If the lifting frame is confirmed to be retracted, it indicates the current process is complete; check if the hydraulic cylinder has retracted. If the lifting frame has not retracted, it indicates the current process is incomplete; in this case, the tower crane's pump station can be locked. If the hydraulic cylinder has retracted, it indicates the current process is complete; check if the step has completed its movement. If the hydraulic cylinder has not retracted, it indicates the current process is incomplete; in this case, the tower crane's pump station can be locked. If the step has not completed its movement, check if there is step support. If step support exists, it indicates the current process is complete; check if the crossbeam pin has been pulled out. If step support does not exist, it indicates the current process is incomplete; in this case, the tower crane's pump station can be locked.If the crossbeam pin is confirmed to be pulled out, it indicates that the current process is complete. The tower crane's status should be adjusted to prohibit cylinder load, and the cylinder should be checked for extension. If the crossbeam pin is confirmed not to be pulled out, it indicates that the current process is not complete, and the tower crane's pump station can be locked. If the cylinder is confirmed to be extended, it indicates that the current process is complete, and the crossbeam pin should be checked for insertion. If the cylinder is confirmed not to be retracted, it indicates that the current process is not complete, and the tower crane's pump station can be locked. If the crossbeam pin is confirmed to be inserted, it indicates that the current process is complete, and the tower crane's status should be adjusted to prohibit cylinder unloading, and the cylinder should be checked for retraction. If the crossbeam pin is confirmed not to be inserted, it indicates that the current process is not complete, and the tower crane's pump station can be locked. If the treading step is completed, determine whether to continue lowering the tower crane. If it is determined to continue lowering, check if the crossbeam pin has been pulled out. If the crossbeam pin has been pulled out, it means the current process is complete, and the tower crane's status is adjusted to prohibit cylinder load. Check if the cylinder has extended, and repeat the above steps. If the crossbeam pin has not been pulled out, it means the current process is not complete, and the tower crane's pump station can be locked. If it is determined not to continue lowering, check if the upper pin is inserted. If the upper pin is inserted, it means the current process is complete, and the tower crane's status is adjusted to prohibit cylinder load. The pump station allows low pressure. Check if there is no load. If yes, end; if not, it means the current process is not complete, and the tower crane's pump station can be locked. If the upper pin is not inserted, it means the current process is not complete, and the tower crane's pump station can be locked.
