Description

Technical Field

[0001] The present application relates to the technical field of tower crane installation, and in particular to a method for monitoring the entire process of height adjustment of a tower crane and a device for monitoring the entire process of height adjustment of a tower crane. Background Art

[0002] The lifting and lowering of a tower crane is the most dangerous process, and is the most prone to major accidents. If an accident occurs during the lifting or lowering process, it will usually cause the tower crane to collapse and be damaged, and the installation workers will be seriously injured or even killed, causing significant economic and personal safety losses, and will also have a bad social impact.

[0003] In tower crane accidents, most of the accidents are caused by improper operation of the installation workers. For example, the lifting beam begins to unload before it is hung on the step, the cylinder starts to push out before the support rod is firmly planted, etc. Therefore, monitoring each key point in the tower crane height adjustment process and ensuring that the operation is in place can greatly reduce the possibility of tower crane accidents.

[0004] Existing tower crane monitoring systems often only monitor the completion of individual key steps, such as whether the steps are in place, whether the tower is tilted, etc. Without monitoring the operation sequence of the entire height adjustment process, the monitoring information will be incomplete, thus ignoring many real risks and failing to identify them. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a method for monitoring the entire process of height adjustment of a tower crane and a device for monitoring the entire process of height adjustment of a tower crane, so as to solve the problem in the prior art that the operation sequence of the entire height adjustment process is not supervised, which will lead to incomplete supervision information, thereby ignoring many real risks and failing to identify them.

[0007] In response to the height adjustment instruction, based on a preset height adjustment standard process, it is judged in sequence whether each process of the tower crane in the height adjustment process is in place;

[0008] When the current process is confirmed to be completed, determine whether the next process is completed;

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

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

[0011] Obtain the oil cylinder pressure of the tower crane in real time;

[0012] Determine whether the oil cylinder pressure of the tower crane reaches the preset pressure value corresponding to the current process;

[0013] When it is determined that the oil cylinder pressure of the tower crane reaches the preset pressure value corresponding to the current process, the pump station of the tower crane is controlled to be locked.

[0014] In an embodiment of the present application, judging whether the process of the tower crane in the height adjustment process is completed includes:

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

[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 working point, it is judged whether the process of the tower crane is fully worked during the height adjustment process.

[0018] In an embodiment of the present application, judging whether the process of the tower crane in the height adjustment process is completed includes:

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

[0020] The image of the working point is sent to the supervisory end, and the supervisory end determines whether the process of the tower crane is in place during the height adjustment process.

[0021] In the embodiment of the present application, the image of the working point corresponding to the process of the tower crane during the height adjustment process is obtained by taking a camera installed at the corresponding working point.

[0022] In the embodiment of the present application, the camera is a detachable camera.

[0023] In the embodiment of the present application, the height adjustment is to raise the tower;

[0024] In response to the height adjustment instruction, based on the preset height adjustment standard process, it is judged in sequence whether each process in the height adjustment process is in place, including:

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

[0026] In the embodiment of the present application, the height adjustment is a tower drop;

[0027] In response to the height adjustment instruction, based on the preset height adjustment standard process, it is judged in sequence whether each process in the height adjustment process is in place, including:

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

[0029] In the embodiment of the present application, it also includes:

[0030] Perform wind force monitoring and / or abnormality monitoring on the tower crane to obtain auxiliary monitoring results.

By judging in sequence whether each process of the tower crane in the height adjustment process is in place, all steps in the height adjustment process can be included in the supervision. When the current process is in place, it is judged whether the next process is in place, so that the operation sequence of the whole process can be supervised, making the supervision information more complete, thereby reducing the risk of ignoring many real risks and failing to identify them. When the process is not in place, by controlling the pump station of the tower crane to lock, the worker will not be able to operate, and the worker will not be able to continue to perform the process, realizing the restriction of the worker's operation, thereby effectively preventing the occurrence of tower crane accidents and improving the reliability and accuracy of the tower crane height adjustment monitoring. The preset height adjustment standard process can clarify the sequential relationship between the steps, which is convenient for identifying risky steps in advance. According to this method, the operating procedures of installation workers can be standardized, targeted training can be carried out, the quality of workers can be improved, and the risk of accidents can be reduced.

[0047] Figure 1 The following schematically shows a flow chart of a method for monitoring the whole process of tower crane height adjustment according to an embodiment of the present application. Figure 1 As shown, the embodiment of the present application provides a method for monitoring the whole process of tower crane height adjustment, which may include the following steps:

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

[0049] In this embodiment, the height adjustment instruction may be input by the user or automatically triggered by the system after determining that the height adjustment of the tower crane is to be performed. The height adjustment of the tower crane includes tower lifting and tower lowering. The preset height adjustment standard process may refer to the process steps set according to the standard tower crane lifting or tower crane lowering process, including all the steps in the tower crane lifting or tower lowering process, which may be pre-set. That is, the preset height adjustment standard process may include a preset tower lifting standard process and a tower lowering standard process. The preset height adjustment standard process includes multiple process steps, and the process steps in the preset height adjustment standard process may be used to judge whether the workers are in place when performing each process. The above judgment of whether the process of the tower crane is in place during the height adjustment process may be to use a camera to capture the image of the key components of the corresponding working point, and then use a pre-trained self-learning algorithm model to judge whether the process is in place based on the image of the key components; the captured image may also be sent to the supervisor to manually judge whether the process is in place, and the judgment result may be input into the system.

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

[0051] In some embodiments, the height adjustment is tower lifting; accordingly, in response to the height adjustment instruction, based on the preset height adjustment standard process, it is judged in turn whether each process in the height adjustment process is in place, including: in response to the tower lifting instruction, based on the preset tower lifting standard process, it is judged in turn whether each process in the tower crane during the tower lifting process is in place.

[0052] In this embodiment, if the current height adjustment is to raise the tower, then after receiving the tower raising instruction, the tower raising process is monitored, that is, according to the preset tower raising standard process, it is determined in turn whether each process of the tower crane in the tower raising process is in place, thereby realizing full-process monitoring of the tower crane's tower raising process.

[0053] In some embodiments, the height adjustment is tower lowering; accordingly, the response to the height adjustment instruction, based on the preset height adjustment standard process, sequentially determines whether each process in the height adjustment process is in place, including: the response to the tower lowering instruction, based on the preset tower lowering standard process, sequentially determines whether each process in the tower crane during the tower lowering process is in place.

[0054] In this embodiment, if the current height adjustment is to lower the tower, then after receiving the tower lowering instruction, the tower lowering process is monitored, that is, according to the preset tower lowering standard process, it is determined in turn whether each process of the tower crane in the tower lowering process is in place, thereby realizing full-process monitoring of the tower crane's tower lowering process.

[0055] In some embodiments, for each process, determining whether the process is completed during the height adjustment of the tower crane comprises the following steps:

[0056] First, images of working points corresponding to the process of adjusting the height of the tower crane are acquired in real time;

[0057] In this embodiment, the image of the working point refers to an image of the working conditions of the corresponding working point in the current process obtained in real time during the tower crane lifting or lowering process. It can be obtained by installing a camera at the corresponding position of the working point and shooting it in real time. In specific implementation, the installation position of the camera can be set and adjusted according to actual conditions.

[0058] For example, in the process of tower lifting, the first process corresponds to the working point of the jacking cylinder, which can be a camera set on the crossbeam of the tower crane, and the image of the jacking cylinder is obtained by reading the picture collected by the camera. The next process corresponds to the working point of the upper pin of the standard section, which can be a camera set on the upper pin plane, and the image of the upper pin of the standard section is obtained by reading the picture of the camera installed on the upper pin plane. The next process corresponds to the working point of the standard section lifting frame, which can also be a camera set on the upper pin plane, and the image of the standard section lifting frame is obtained by reading the picture of the camera installed on the upper pin plane. The image of the standard section lifting frame can be used to determine the hanging of the standard section lifting frame. A camera can also be installed on the bottom walking net of the upper installation, and the image of the standard section lifting frame can be obtained by reading the picture of the camera installed on the bottom walking net of the upper installation. The image of the standard section lifting frame can be used to determine the introduction and exit of the standard section lifting frame. The next process corresponds to the working point of the lower pin of the standard section, which can also be a camera installed on the bottom walking net of the upper installation, and the image of the lower pin of the standard section is obtained by reading the picture of the camera installed on the bottom walking net of the upper installation. The next process corresponds to the working point of the step-changing support rod, which can also be a camera installed on the bottom walking net of the upper body, and the image of the step-changing support rod is obtained by reading the camera image installed on the bottom walking net of the upper body. The next process corresponds to the working point of the beam safety pin shaft, which can be a camera installed on the beam of the tower crane, and the image of the beam safety pin shaft is obtained by reading the image collected by the camera.

[0059] Then, 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;

[0060] In this embodiment, the preset target detection model may be a pre-trained target detection model, which is used for target detection of key components in the image of the working point, and the state of the working point is determined by detecting the information of the key components, so as to detect the working state of the current working point. Different working points may have different corresponding key components, which may be determined according to actual conditions.

[0061] Finally, based on the working status of the working point, it is determined whether the tower crane has completed the work in 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 so, it means that the current process is working properly. If not, it means that the current process is not working properly.

[0063] By detecting the key components in the image of the working point through the preset target detection model, the working status of the working point can be determined quickly and accurately, and then it can be quickly and accurately judged whether the process of the tower crane in the height adjustment process is in place, thereby realizing visual monitoring and identification of all key points in the tower crane jacking process.

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

[0065] First, images of working points corresponding to the process of adjusting the height of the tower crane are acquired in real time;

[0066] In this embodiment, the image of the working point refers to an image of the working conditions of the corresponding working point in the current process obtained in real time during the tower crane lifting or lowering process. It can be obtained by installing a camera at the corresponding position of the working point and shooting it in real time. In specific implementation, the installation position of the camera can be set and adjusted according to actual conditions.

[0067] Then, the image of the working point is sent to the supervisory end, and the supervisory end determines whether the process of the tower crane is in place during the height adjustment process.

[0068] In this embodiment, the above-mentioned supervision end can be judged manually, for example, it can be sent to the staff's mobile phone to obtain the work completion status judged by the staff to determine whether the current process is completed.

[0069] By sending the image of the working point to the supervision end, the supervision end determines whether the process of the tower crane is working properly during the height adjustment process, so that the judgment is accurate and reliable, thereby improving the accuracy and reliability of the whole process monitoring of the tower crane height adjustment.

[0070] The above-mentioned images of the working points are used in judging whether the process of the tower crane is completed during the height adjustment process. In some embodiments, the images of the working points corresponding to the process of the tower crane during the height adjustment process are obtained by taking pictures with cameras installed at the corresponding working points.

[0071] In this embodiment, the camera can be installed at each corresponding process work point, and can be set according to different work points, and can be flexibly set according to actual conditions. For example: for the standard section upper pin work point, it can be set on the upper pin plane to obtain the image of the upper pin of the standard section by reading the picture of the camera installed on the upper pin plane. For the standard section lifting frame work point, it can also be set on the upper pin plane to obtain the image of the standard section lifting frame by reading the picture of the camera installed on the upper pin plane, and the image of the standard section lifting frame can be used to judge the hanging of the standard section lifting frame. It can also be installed on the upper bottom walking net to obtain the image of the standard section lifting frame by reading the picture of the camera installed on the upper bottom walking net, and the image of the standard section lifting frame can be used to judge the introduction and exit of the standard section lifting frame. For the standard section lower pin work point, it can also be installed on the upper bottom walking net to obtain the image of the lower pin of the standard section by reading the picture of the camera installed on the upper bottom walking net. For the step-changing support rod working point, a camera may be installed on the walking net at the bottom of the upper body, and the image of the step-changing support rod may be obtained by reading the camera image installed on the walking net at the bottom of the upper body. For the crossbeam safety pin working point, a camera may be set on the crossbeam of the tower crane, and the image of the crossbeam safety pin may be obtained by reading the image collected by the camera.

[0072] During the height adjustment process of the tower crane, the image of the corresponding working point of the process is captured by a camera installed at the corresponding working point, so that the image of the working point can effectively reflect the operating conditions of the corresponding working point, which helps to improve the reliability of judging whether the process is working properly.

[0073] Wherein, the camera is a detachable camera.

[0074] In this embodiment, the detachable camera can be removed from the equipment, its position can be adjusted as needed or it can be used alone, and it can be flexibly set according to the working conditions to meet the needs of various scenarios.

[0075] Step 220: When it is determined that the current process is completed, determine whether the next process is completed;

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

[0077] Step 230: When it is determined that the current process has not been completed, the pump station of the tower crane is controlled to be locked to achieve full process monitoring of the height adjustment of the tower crane.

[0078] In this embodiment, if the current process is not completed, it means that the worker has made an error in the current process. In order to avoid tower crane accidents, the pump station of the tower crane can be controlled to be locked. After the pump station is locked, the worker will not be able to operate it, and the worker will not be able to continue to perform the process, thus limiting the worker's operation and effectively preventing tower crane accidents. The above-mentioned control of the tower crane pump station locking can be directly issued by issuing a command to lock, or it can be automatically locked.

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

[0080] First, obtain the cylinder pressure of the tower crane in real time;

[0081] In this embodiment, a pressure sensor may be arranged near the pump station, and specifically, may be arranged on the oil line to the oil cylinder, so as to acquire the oil cylinder pressure in real time.

[0082] Then, determining whether the oil cylinder pressure of the tower crane reaches 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, and different processes can have different pressure values. For example, the two states of prohibiting cylinder loading and prohibiting cylinder unloading have different critical values, and the current process determines which state it is in, and then determines the corresponding pressure value. The above judgment can be to compare the cylinder pressure with the preset pressure value corresponding to the current process to determine whether it is reached.

[0084] Then, when it is determined that the oil cylinder pressure of the tower crane reaches the preset pressure value corresponding to the current process, the pump station of the tower crane is controlled to be locked.

[0085] In this embodiment, the pump station locking of the tower crane can be performed through an intelligent two-way lock. For example, when the cylinder load is prohibited, the intelligent two-way lock determines whether the cylinder pressure reaches a preset pressure value. If so, the pump station of the tower crane is locked.

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

[0087] In the above implementation process, by responding to the height adjustment instruction, based on the preset height adjustment standard process, it is judged in sequence whether each process of the tower crane in the height adjustment process is in place; when it is determined that the current process is in place, it is judged whether the next process is in place; when it is determined that the current process is not in place, the pump station of the tower crane is controlled to be locked, so as to realize the full process monitoring of the height adjustment of the tower crane. By judging in sequence whether each process of the tower crane in the height adjustment process is in place, all steps in the height adjustment process can be included in the supervision. When the current process is in place, it is judged whether the next process is in place, so that the operation sequence of the whole process can be supervised, making the supervision information more complete, thereby reducing the risk of ignoring many real risks and failing to identify them. When the process is not in place, by controlling the pump station of the tower crane to lock, the worker will not be able to operate, and the worker will not be able to continue to perform the process, realizing the restriction of the worker's operation, thereby effectively preventing the occurrence of tower crane accidents and improving the reliability and accuracy of the tower crane height adjustment monitoring. The preset height adjustment standard process can clarify the sequential relationship between the steps, which is convenient for identifying risky steps in advance. According to this method, the operating procedures of installation workers can be standardized, targeted training can be carried out, the quality of workers can be improved, and the risk of accidents can be reduced.

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

[0089] In this embodiment, the above abnormal monitoring includes the tower crane trim monitoring, etc. The above wind monitoring and / or abnormal monitoring can be performed all the time in the whole process. The above wind monitoring and abnormal monitoring can be realized by using existing technologies, which will not be described in detail here.

[0090] By performing wind force monitoring and / or abnormality monitoring on the tower crane to obtain auxiliary monitoring results, the reliability and accuracy of monitoring the height adjustment of the tower crane can be further improved.

[0091] The following describes the scheme from the perspectives of tower crane lifting and lowering processes. Figure 2 and Figure 3 , Figure 2 A schematic diagram of a tower lifting process of a tower crane according to an embodiment of the present application is schematically shown; Figure 3 The schematic diagram of the tower lowering process of the tower crane according to the embodiment of the present application is schematically shown.

[0092] It should be noted that in Figure 2 and Figure 3In the figure, the judgment step in red indicates that the step can be a non-visual judgment, which can be judged by tower crane working condition information or manual confirmation by workers. The blue square indicates that only cylinder loading is allowed or cylinder unloading is prohibited in this step. In this state, the weight of the tower crane is borne by the jacking cylinder. The white square indicates that only cylinder unloading is allowed or cylinder loading is prohibited in this step. In this state, the weight of the tower crane cannot be borne by the jacking cylinder, but by the tower body or the step-changing support rod. If the judgment diamond box does not have a negative arrow, the step will be re-judged by default.

[0093] Please see Figure 2For tower crane tower lifting, a preset tower lifting standard process can be pre-set. When monitoring the whole tower crane tower lifting process, first respond to the tower lifting instruction. The tower crane is in the state of prohibiting cylinder load. It is judged whether the cylinder of the tower crane is retracted. If the cylinder of the tower crane is retracted, it means that the current process is in place. Then it is judged whether the crossbeam pin of the tower crane is inserted; if the cylinder of the tower crane is not retracted, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. When it is determined that the crossbeam pin of the tower crane is inserted, it means that the current process is in place, and then it is judged whether the lifting frame of the tower crane is hung in; when it is determined that the lifting frame of the tower crane is hung in, it means that the current process is in place, and then it is judged whether the tower crane is in the working condition balancing state; when it is determined that the lifting frame of the tower crane is not hung in, it means that the current process is not in place, and then the pump station of the tower crane can be controlled to be locked. When it is determined that the tower crane is in the working balance state, determine whether the upper pin shaft of the tower crane is pulled out; when the upper pin shaft of the tower crane is pulled out, it means that the current process is in place, and the state of the tower crane is adjusted to the state of prohibiting the cylinder unloading, and the pump station enables high pressure to determine whether the tower crane is the first tower crane to be jacked up; when the upper pin shaft of the tower crane is not pulled out, it means that the current process is not in place, and the pump station of the tower crane can be controlled to lock. When it is determined that the tower crane is the first tower crane to be jacked up, determine whether the jacking function of the tower crane is normal; when it is determined that the jacking function of the tower crane is normal, determine whether there is an offset when the tower crane is installed, that is, determine whether the tenon is vertical; when it is determined that the jacking function of the tower crane is abnormal, it means that there is an abnormality and the process ends directly. When it is determined that the tower crane is not the first tower crane to be jacked up, determine whether there is an offset when the tower crane is installed, that is, determine whether the tenon is vertical. When it is determined that the tenon is vertical, it means that the current process is in place, and it is determined whether the cylinder is extended; when it is determined that the tenon is not vertical, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. When it is determined that the cylinder is extended, it is determined whether the step is completed. If the step is completed, it is determined whether the lifting frame is introduced; if the step is not completed, it is determined whether there is a step support. If there is a step support, it means that the current process is in place, and it is determined whether the beam pin is pulled out; if there is no step support, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. When it is determined that the beam pin is pulled out, it means that the current process is in place, and the state of the tower crane is adjusted to the state of prohibiting the cylinder load, and it is determined whether the cylinder is retracted; when it is determined that the beam pin is not pulled out, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. When it is determined that the cylinder is retracted, it means that the current process is in place, and it is determined whether the beam pin is inserted; when it is determined that the cylinder is not retracted, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked.When it is determined that the crossbeam pin is inserted, it means that the current process is in place, and the state of the tower crane is adjusted to the state of prohibiting the cylinder unloading, and it is judged whether the cylinder is extended; when it is determined that the crossbeam pin is not inserted, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. When it is determined that the lifting frame is introduced, it means that the current process is in place, and it is judged whether the lower pin shaft is inserted; when it is determined that the lifting frame is not introduced, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. When it is determined that the lower pin shaft is inserted, it means that the current process is in place, and it is judged whether the lifting frame is withdrawn; when it is determined that the lower pin shaft is not inserted, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. When it is determined that the lifting frame is withdrawn, it means that the current process is in place, and it is judged whether to continue jacking, that is, whether to continue lifting the tower; when it is determined that the lifting frame is not withdrawn, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. The above judgment on whether to lift can be made manually or by setting the number of lifting times.

Determine whether the cylinder is extended and execute the above steps again; if it is determined that the crossbeam pin is not pulled out, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked. If it is determined not to continue lowering the tower, determine whether the upper pin shaft is inserted; if it is determined that the upper pin shaft is inserted, it means that the current process is in place, and the state of the tower crane is adjusted to the state of prohibiting the cylinder load. The pump station allows low pressure, and it is determined whether there is no load. If so, it ends. If not, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked; if it is determined that the upper pin shaft is not inserted, it means that the current process is not in place, and the pump station of the tower crane can be controlled to be locked.
