Description

Technical Field

[0001] The present invention relates to the field of intelligent detection technology, and in particular to a tower crane jacking monitoring and identification system, method, and machine-readable storage medium. Background Art

[0002] Tower crane installation is a collaborative process requiring strict monitoring of all operations. The main steps include: 1. Installing the crane base frame and foundation section; 2. Installing the sling frame; 3. Installing the tower cap and slewing bearing; 4. Installing the balancing arm; 5. Installing the jib; 6. Connecting power and threading ropes; 7. Raising the crane; and 8. Installation and commissioning. The jacking process involves continuously adding standard sections to the foundation section until the jib reaches the target lifting height.

[0003] However, during the process of implementing the present invention, the inventors discovered that the prior art lacked a monitoring system for monitoring the status of standard section addition, the number of sections being lifted, and the lifting height. During lifting operations, only a dedicated person could monitor the status of the section addition operation, record the number of sections being lifted and the lifting height, and complete a tower crane lifting supervision record after the lifting and installation were completed. This manual method of managing tower crane height can easily lead to the omission of critical information due to negligence, resulting in inadequate monitoring of the tower crane and potentially causing safety accidents. Summary of the Invention

[0004] The purpose of the embodiment of the present invention is to provide a tower crane jacking monitoring and identification system, which monitors the hook status in real time, identifies and records the status of the tower crane during the jacking process, and determines whether the tower crane jacking is completed.

[0005] In order to achieve the above-mentioned object, an embodiment of the present invention provides a tower crane jacking monitoring and identification system, which includes:

[0006] Hook height sensor, used to monitor the height of the hook from the ground;

[0007] A hook amplitude sensor is used to monitor the horizontal displacement amplitude of the hook relative to the boom heel;

[0008] A load weight sensor for monitoring the load weight of the hook; and

[0009] The monitor is used to split the tower crane jacking process into multiple sequential operating states, each operating state corresponding to a different state value. During the tower crane jacking process, the real-time monitoring data obtained by the hook height sensor, hook amplitude sensor and load weight sensor are used to identify and record the operating state of the tower crane jacking process and determine whether the tower crane jacking is completed.

[0010] Preferably, the monitor is used to execute: when the real-time monitoring data meets any one of the preset operating status sets, record and output that the tower crane is in the operating status, and continue to monitor whether the tower crane is in the next state of the operating status in the operating status set until the tower crane is monitored to be in the last state in the operating status set. The operating status set includes any of the following combinations: standard section lifting, standard section lifting height is the highest, standard section reaches the minimum amplitude, standard section unloading at the highest point, next standard section lifting, and boom leveling and adding sections.

[0011] Preferably, when the monitor identifies that the current operation has passed through all the operation states in the operation state set and started the first state in the operation state set, it is determined that the tower crane has completed a jacking operation; and

[0012] The monitor is also used to record: the current number of sections raised by the tower crane and / or the current lifting height of the tower crane, wherein when a jacking operation is completed, the current number of sections raised by the tower crane is accumulated by 1, and the current lifting height of the tower crane is accumulated by one standard section height.

[0013] Optionally, the monitor performs one or more of the following operations:

[0014] The current operating state of the tower crane is identified as the standard section hoisting state when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor is within the preset height value;

[0015] The current operating state of the tower crane is identified as the highest hoisting height of the standard section when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor meets the current hoisting height of the tower crane;

[0016] The current operating state of the tower crane is identified as the standard section reaching the minimum amplitude when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current lifting height of the tower crane, and the monitoring value of the hook amplitude sensor is within the preset amplitude value;

[0017] The current operating state of the tower crane is identified as unloading at the highest point of the standard section when the following conditions are met: the monitoring value of the load weight sensor is less than a preset minimum weight value, the monitoring value of the hook height sensor is consistent with the current lifting height of the tower crane, and the monitoring value of the hook amplitude sensor is within the preset amplitude value;

[0018] The current operating state of the tower crane is identified as the lifting of the next standard section when the following conditions are met: after the standard section is unloaded at its highest point, the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor is within the preset height value; and

[0019] When the following conditions are met, the current operating state of the tower crane is identified as the boom leveling and adding sections: after the next standard section is hoisted, when the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current lifting height of the tower crane, and the monitoring value of the hook amplitude sensor meets within a second preset amplitude value, it is determined that the current state is the boom leveling state;

[0020] When the duration of the boom leveling state meets the preset duration, it is determined that one section addition is completed, and the monitor records the current number of sections raised by the tower crane plus 1, and records the current lifting height of the tower crane plus a preset standard section height.

[0021] Preferably, when the following conditions are met, it is determined that a section addition is completed: the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current lifting height of the tower crane, and the monitoring value of the hook amplitude sensor is within the preset amplitude value.

[0022] Preferably, the tower crane jacking is completed when the following conditions are met: the monitoring value of the load weight sensor is less than a preset minimum weight value, and the monitoring value of the hook height sensor is within a preset height value.

[0023] Furthermore, the above system also includes a boom rotation angle sensor for monitoring the rotation angle of the boom relative to a preset reference direction during the leveling and segmentation of the boom.

[0024] In another aspect, the present invention provides a tower crane jacking monitoring and identification method, the method comprising:

[0025] Monitor the height of the hook from the ground;

[0026] Monitoring the horizontal displacement of the hook relative to the boom heel;

[0027] monitoring the hook load weight; and

[0028] The tower crane jacking process is divided into multiple sequential operating states, each operating state corresponds to a different state value. During the tower crane jacking process, the operating state of the tower crane jacking process is identified and recorded according to the obtained hook height, hook amplitude and load weight, and it is determined whether the tower crane jacking is completed.

[0029] When the real-time monitoring data meets any one of the preset operating status sets, it is recorded and output that the tower crane is in the operating status, and the tower crane is continuously monitored to see whether it is in the next state of the operating status in the operating status set until the tower crane is monitored to be in the last state in the operating status set. The operating status set includes any of the following combinations: standard section lifting, standard section lifting to the highest height, standard section reaching the minimum amplitude, standard section unloading at the highest point, next standard section lifting, boom leveling and section addition.

[0030] Preferably, when it is identified that the current operation has passed through all the operation states in the operation state set and started the first state in the operation state set, it is determined that the tower crane has completed one jacking operation; and

[0031] The current number of sections raised by the tower crane and / or the current lifting height of the tower crane are also recorded. When a jacking operation is completed, the current number of sections raised by the tower crane is accumulated by 1, and the current lifting height of the tower crane is accumulated by one standard section height.

[0032] Furthermore, during the leveling and segmenting of the boom, the boom's rotation angle relative to a preset reference direction is monitored by a boom rotation angle sensor.

[0033] Optionally, the current operating state of the tower crane is identified as the standard section hoisting state when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor is within a preset height value;

[0034] The current operating state of the tower crane is identified as the highest hoisting height of the standard section when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor meets the current hoisting height of the tower crane;

[0035] The current operating state of the tower crane is identified as the standard section reaching the minimum amplitude when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current lifting height of the tower crane, and the monitoring value of the hook amplitude sensor is within the preset amplitude value;

[0036] The current operating state of the tower crane is identified as unloading at the highest point of the standard section when the following conditions are met: the monitoring value of the load weight sensor is less than a preset minimum weight value, the monitoring value of the hook height sensor is consistent with the current lifting height of the tower crane, and the monitoring value of the hook amplitude sensor is within the preset amplitude value;

[0037] The current operating state of the tower crane is identified as the lifting of the next standard section when the following conditions are met: after the standard section is unloaded at its highest point, the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor is within the preset height value; and

[0038] When the following conditions are met, the current operating state of the tower crane is identified as the boom leveling and adding sections: after the next standard section is hoisted, when the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current lifting height of the tower crane, and the monitoring value of the hook amplitude sensor meets within a second preset amplitude value, it is determined that the current state is the boom leveling state;

[0039] When the duration of being in the boom leveling state meets the preset duration, it is determined that one section addition is completed, the current number of sections raised by the tower crane plus 1 is recorded, and the current lifting height of the tower crane plus a preset standard section height is recorded.

[0040] Preferably, when the following conditions are met, it is determined that a section addition is completed: the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current lifting height of the tower crane, and the monitoring value of the hook amplitude sensor is within the preset amplitude value.

[0041] Preferably, the tower crane jacking is completed when the following conditions are met: the monitoring value of the load weight sensor is less than a preset minimum weight value, and the monitoring value of the hook height sensor is within a preset height value.

[0042] On the other hand, the present invention provides a machine-readable storage medium having instructions stored thereon, the instructions being used to enable a machine to execute any of the tower crane jacking monitoring and identification methods described above in the present application.

[0043] Through the above technical solution, the sensor simultaneously monitors the height of the hook from the ground, the horizontal displacement amplitude of the hook relative to the boom heel, and the weight of the hook load, and sends the monitoring data to the monitor. The monitor divides the tower crane jacking process into multiple sequential operating states, and each operating state corresponds to a different state value. During the tower crane jacking process, the monitor identifies and records the operating state of the tower crane jacking process based on the obtained hook height, hook amplitude and load weight, and determines whether the tower crane jacking is completed, saving manpower monitoring and recording work.

[0057] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0058] The tower crane lifting monitoring and identification system of the present invention can be used for the status identification and recording of the tower crane lifting process, and its composition structure should at least include the following: Figure 1 The components shown below are combined Figure 1 and Figure 2 The composition of an embodiment of a tower crane jacking monitoring and identification system of the present invention is introduced.

[0059] In this embodiment, the tower crane lifting monitoring and identification system includes a hook height sensor, a hook amplitude sensor, a load weight sensor and a monitor. Among them, the hook amplitude sensor and the hook amplitude sensor are installed in the following manner: Figure 2The wire rope drum 2 is shown in the figure. The hook height sensor monitors the height of the hook 1 from the ground, and the hook amplitude sensor monitors the horizontal displacement of the hook 1 relative to the boom heel. The load weight sensor monitors the weight of the object being hoisted by the hook. The hook height sensor, hook amplitude sensor, and load weight sensor transmit real-time monitoring data to the monitor. Based on the received real-time monitoring data, the monitor identifies and records the status of the tower crane's jacking process and determines whether the tower crane jacking process is complete.

[0060] During the tower crane lifting process, several standard sections are added one by one to achieve the desired lifting height. The monitor is used to monitor the status of each standard section during the lifting process, determine whether the current section addition process is complete, and determine whether the tower crane lifting process is complete. When a section addition process is completed, the current number of sections and the current lifting height of the tower crane are recorded, and the tower crane lifting process is determined based on preset conditions.

[0061] In some embodiments, the monitoring and recording operations may generate a jacking process log, and relevant personnel may edit construction documents based on the log.

[0062] It is understandable that the conditions for determining whether the tower crane jacking is completed can be set according to actual needs. For example, the current lifting height can reach a predetermined height, the current cumulative number of added sections has reached a predetermined number, or the current sensor monitoring data meets the preset requirements.

[0063] Compared with the prior art, the technical advantages of this embodiment and the above different implementations are:

[0064] Compared with manual monitoring and recording in existing construction processes, the tower crane jacking monitoring and identification system of this embodiment can eliminate the need for construction workers to perform additional monitoring and recording operations, thus avoiding omissions or even safety accidents caused by human errors.

[0065] In some embodiments, the status of the tower crane hoisting process includes one or more of the following: the number of completed hoisting sections, the current tower crane hoisting height, and the current hoisting section status. The hoisting steps for a standard section should at least include: hoisting the standard section, hoisting the standard section to the highest height, reaching the minimum amplitude, unloading the standard section at the highest point, hoisting the next standard section, and leveling the boom and adding sections.

[0066] It should be noted that in a section lifting operation, a standard section must first be lifted to a position that meets the current lifting height, then moved to the arm foot of the boom, and then unloaded to the sleeve to prepare for superimposing the standard section on the tower body, and then another standard section is lifted to the current lifting height and received at a suitable amplitude position as a counterweight to make it easier to balance the boom. After the balancing is completed, the jacking hydraulic mechanism is raised, and the prepared standard section is inserted into the sleeve and fixed, thus completing a section addition. Repeating the above operations can complete the addition of several predetermined standard sections one by one until the entire jacking operation is completed.

[0067] In some embodiments, the tower crane jacking monitoring and identification system further includes a boom rotation angle sensor, which is used to monitor the rotation angle of the boom relative to a preset reference direction during the leveling and sectioning of the boom, so that the boom remains horizontal to ensure the operability and safety of the operation process of introducing and fixing the standard section into the sleeve.

[0068] In some embodiments, the current section lifting state is identified as the standard section lifting state when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor is within a preset height value;

[0069] In some embodiments, the current lifting state is identified as the standard section lifting height being the highest when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor meets the current tower crane lifting height;

[0070] In some embodiments, the current lifting state is identified as the standard section reaching the minimum amplitude when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current tower crane lifting height, and the monitoring value of the hook amplitude sensor is within a preset amplitude value;

[0071] In some embodiments, the current lifting state is identified as unloading at the highest point of the standard section when the following conditions are met: the monitoring value of the load weight sensor is 0, the monitoring value of the hook height sensor is consistent with the current tower crane lifting height, and the monitoring value of the hook amplitude sensor is within the preset amplitude value;

[0072] In some embodiments, the current lifting state is identified as the next standard section lifting state when the following conditions are met: after the standard section is unloaded at the highest point, the monitoring value of the load weight sensor meets the preset standard section weight, and the monitoring value of the hook height sensor is within the preset height value;

[0073] In some embodiments, when the following conditions are met, the current section lifting state is identified as the boom leveling and section adding state: after the next standard section lifting state, when the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current tower crane lifting height, and the monitoring value of the hook amplitude sensor meets the second preset amplitude value, it is determined that the current state is the boom leveling state, and when the duration of the boom leveling state meets the preset duration, it is determined that one section adding is completed.

[0074] Combine Figure 2 Describe the state characteristics of the boom leveling and adding sections. Figure 2 In the figure, the standard section 4 has been placed at the position of the sleeve 3, and the next standard section 5 has been hoisted to a position that meets the current lifting height of the tower crane as a counterweight. The displacement of the hook 1 relative to the arm of the boom can be adjusted through the wire rope drum 2, and the standard section 4 can be pushed toward the tower body and introduced into the sleeve to complete the section addition operation.

[0075] It should be noted that the method for setting the reference value required for the above judgment can be set according to the actual parameters of the tower crane. Among them, the preset height value should be set as a threshold based on whether it meets the current lifting height. For example, it can be based on the current lifting height minus a value that is equivalent to the height difference between the hook position and the boom; the preset standard section weight should be set according to the standard section weight parameters of the tower crane currently in operation; the preset amplitude value should be set according to the parameters of the tower crane currently in operation so that the standard section to be added is at the sleeve 3, generally set to 1-2 meters; the preset time length is to ensure that sufficient time is reserved for introducing the standard section 4 into the sleeve for fixation and inspection operations, for example, it can be set to 20 minutes.

[0076] In some embodiments, if it is determined that one section addition has been completed, the monitor records the number of completed sections plus 1 and the current tower crane lifting height plus a preset standard section height.

[0077] In some embodiments, a section addition is determined to be completed when the following conditions are met: the monitoring value of the load weight sensor meets the preset standard section weight, the monitoring value of the hook height sensor meets the current tower crane lifting height, and the monitoring value of the hook amplitude sensor is within the preset amplitude value.

[0078] In some embodiments, the tower crane jacking is determined to be completed when the following conditions are met: the monitoring value of the load weight sensor is 0, and the monitoring value of the hook height sensor is within a preset height value.

[0079] It should be noted that the above requirement that the monitoring value of the load weight sensor is 0 refers to the case where the hook is unloaded. In fact, when the sensor value is small enough to be negligible, it can be regarded as meeting the value of 0.

[0080] Compared with the existing technology, the technical advantages of this embodiment and the above-mentioned different implementation methods are that they can not only monitor and record the status of the jacking process, eliminating manual monitoring operations and avoiding human errors, but also further ensure the safety and convenience of the jacking process.

[0081] The following describes another embodiment of the tower crane jacking monitoring and identification system of the present invention. This embodiment integrates the above-mentioned embodiments and implementation methods into a tower crane, which is provided with a safety monitoring system. The system includes: Figure 3 The acquisition box and safety monitoring host are shown. In this embodiment, the jacking monitoring and identification system of the present invention is integrated into the safety monitoring system. During tower crane jacking operations, the hook height sensor, hook amplitude sensor, load weight sensor, and monitor of the present invention can operate in the manner described in the previous embodiment as a separate jacking monitoring and identification system, while also sharing monitoring and identification data with the safety monitoring system.

[0082] In this embodiment, on the one hand, the hook height sensor, hook amplitude sensor and load weight sensor of the jacking monitoring and identification system of the present invention are integrated into Figure 3 The AI sensor information acquisition module of the tower crane acquisition box shown is used to monitor status values in real time and transmit them to the safety monitoring host. Furthermore, the monitor of the jacking monitoring and identification system of the present invention is integrated into the jacking monitoring module of the safety monitoring host to receive the monitoring status values collected by the sensors. The monitor of the jacking monitoring and identification system of the present invention then monitors and records the status of the jacking process.

[0083] The following is in conjunction with the instructions Figure 4 This article describes an embodiment of the tower crane jacking monitoring and identification method of the present invention. This embodiment can be applied to the process monitoring and recording of conventional jacking operations. The jacking operation and the addition of a standard section are similar to those of the previous embodiment. This embodiment further illustrates the implementation of the tower crane jacking monitoring and identification method of the present invention.

[0084] The implementation process of this embodiment includes:

[0085] Step 1: Monitor the height of the hook from the ground;

[0086] Step 2: monitoring the horizontal displacement amplitude of the hook relative to the boom heel;

[0087] Step 3: monitoring the hook load weight;

[0088] Step 4: Identify and record the state of the tower crane lifting process based on the acquired hook height, hook amplitude and load weight, and determine whether the tower crane lifting is completed.

[0089] It should be noted that steps 1-3 in the above steps are all real-time monitoring processes, and monitoring values can also be obtained according to the preset sampling frequency. Steps 1-3 do not represent a strict acquisition order, nor do they even mean that steps 1-3 are strictly and completely executed. In fact, the judgment conditions for the height and amplitude of the hook and the load weight are different in different states during the tower crane jacking operation and the section addition operation. The monitoring values of steps 1-3 can be obtained according to actual needs at the current time and state of the jacking operation.

[0090] As mentioned above, this embodiment can be applied to the process monitoring and recording of conventional jacking operations. Its jacking operation and the operation of adding a standard section are no different from the aforementioned embodiments. Therefore, for the different states of the tower crane jacking operation process and the process of adding a standard section, as well as the judgment conditions for the height and amplitude of the hook and the load weight in different states, and the judgment of whether an addition of a section is completed and whether a jacking process is completed, you can refer to the description of the previous embodiment and will not go into details here.

[0091] The following is in conjunction with the instructions Figure 5 The process of another embodiment of the tower crane jacking monitoring and identification method of the present invention is introduced.

[0092] like Figure 5 As shown, after the embodiment starts to identify the jacking operation, the monitor is always in the identification operation of determining the current state based on the monitoring data. After determining that the boom is leveled and the section addition is completed, the current cumulative number of completed sections and the current lifting height are recorded. This indicates that one section addition process has been completed. At this time, it is necessary to determine whether the jacking operation is completed. If the judgment result is that it has been completed, the identification and monitoring process of this jacking operation is terminated. If the judgment result is that it has not been completed, the monitoring process of the next section addition operation is started.

[0093] That is to say, Figure 5 The following judgments are key nodes in a section adding operation: lifting the standard section, lifting the standard section to the highest height, reaching the minimum amplitude of the standard section, unloading the standard section at the highest point, lifting the next standard section, and leveling the boom and adding sections. If all nodes meet the judgment conditions in sequence, it can be considered that a section adding operation is completed. If 8 sections need to be added in a jacking operation, the above nodes need to be cyclically identified and judged 8 times. After completing 8 section adding operations, the current cumulative number of completed sections is 8, and the current lifting height = basic lifting height + one standard section height * 8. In actual operations, after each recording of the section adding information, it is necessary to determine whether the jacking operation is completed.

[0094] The above-mentioned determination of multiple key nodes in a section adding operation and determination of whether the lifting operation is completed can be performed based on the monitoring values of the present invention. The determination conditions of the key nodes in a section adding operation can be:

[0095] ①, Standard section lifting: t≈T, h <H0;

[0096] ②. The maximum lifting height of the standard section: t≈T, h≈H;

[0097] ③. The standard section reaches the minimum amplitude: t≈T, h≈H, l≈L;

[0098] ④ Unloading at the highest point of the standard section: t≈0, h≈H, l≈L;

[0099] ⑤. Hoist the next standard section: t≈T, h <H0;

[0100] ⑥. Level the boom and add sections: t≈T, h≈H, l>5m, r=preset fixed value.

[0101] In the above judgment conditions, h is the monitoring value of the hook height, l is the monitoring value of the hook amplitude, t is the monitoring value of the load weight, r is the monitoring value of the swing angle of the boom, T is the weight of a standard section, H is the current lifting height of the tower crane, L is the preset minimum amplitude value (the minimum amplitude value of the tower crane is generally 1-2m), H0 is the basic lifting height value of the tower crane (if it is a self-lifting tower crane, the initial lifting height is generally 10m), H is the current lifting height value of the tower crane, t≈0 is to monitor whether the hook is in an empty state. In fact, whether the monitoring value of the load weight is less than the preset minimum weight value can be used to determine whether the monitoring value of the load weight is approximately equal to 0.

[0102] The monitoring process of a section adding operation is as follows:

[0103] (1) Preparation for adding sections. When the jacking preparation work begins, the standard section needs to be placed on the jacking frame. When the monitoring shows that the lifting weight is T at a height of 0 meters, ① is satisfied. At the same time, the hook moves to the arm heel. If the monitoring height meets ① and ② conditions, the amplitude moves to l to meet ①, ②, and ③.

[0104] (2) The process of adding sections. After completing the preparation for adding sections, maintain the above conditions and at the same time, the weight at conditions ② and ③ becomes ≈0 to meet condition ④. At this time, the standard section to be added is ready. Next, it is necessary to lift a standard section as a counterweight. The hook needs to fall to the ground and then lift a standard section again. At this time, condition ⑤ is met. Then lift the big hook to a high place. At this time, conditions ⑤ and ⑥ are met. After the balancing conditions are met, the movement amplitude keeps the big arm horizontal, and the height, amplitude, rotation and weight remain unchanged. At this time, conditions ⑤ and ⑥ are met. The operation is greater than 20 minutes. Through the above judgment, it can be determined that the tower crane has completed a section lifting action. The above judgment that the operation is greater than 20 minutes is set according to the actual operation requirements in this embodiment, and should be set according to specific implementation conditions in other operations.

[0105] (3) Preparation for the next section addition or completion of jacking. After the section addition process is completed, if the weight of the trimmed standard section is detected to be above the boom heel, the crane enters the preparation stage for jacking the second standard section. The above process is repeated. When the weight is detected to be ≈0, the jacking process is terminated. After 3 hours of stabilization time, the crane height is increased by (standard section length x number of standard sections added).

[0106] In this embodiment, the conditions for determining whether the jacking operation is completed are:

[0107] ⑦. Lifting operation completed: t≈0, h<H0,l> 5m.

[0108] The above judgment conditions indicate that, according to the operating procedures of this embodiment, the hook should be stopped at a low position and the load should be removed after the jacking operation is completed. The technicians can set the jacking operation completion conditions according to the actual operating procedures.

[0109] It is particularly important to note that Figure 5 In the flowchart shown, the corresponding process of the above judgments ①-⑦ not only includes the above judgment conditions, but also can set the operation time of each operation state according to the needs of the construction work. When the tower crane is identified as being in any operation state, the timing starts. As long as it is within the set time range corresponding to the operation state and meets the corresponding state value, it can be considered that the tower crane is currently in this operation state.
