Description

Technical Field

[0001] This application relates to the field of tower crane equipment, specifically a hook device and a tower crane control system. Background Technology

[0002] Tower cranes are indispensable key equipment in modern construction. Their main body consists of a tall steel tower and a long, horizontally rotating jib. They are primarily used for the efficient and precise lifting of heavy building materials (such as steel bars, concrete, and precast components) and construction equipment to high-altitude work surfaces. With their powerful lifting height, coverage area, and lifting capacity, tower cranes have greatly overcome the limitations of manual handling, significantly improving construction efficiency. As the main force for vertical and horizontal transportation in high-rise buildings, large bridges, power plants, and other projects, tower cranes have become one of the most iconic facilities on modern construction sites.

[0003] In existing technologies, construction sites are typically divided into multiple hoisting zones, each requiring an alarm. When the system detects unauthorized personnel entering a hoisting zone, the alarm in that zone will sound to alert or notify them to leave. However, this approach has several significant drawbacks: First, due to the large number of hoisting zones on a construction site and the limited effective coverage of a single alarm, a large number of devices are required, leading to high costs. Second, the system uses the hook's height above the ground as the trigger condition; when the hook is at a high position, even if personnel illegally enter, the alarm will not activate because the trigger height has not been reached. Furthermore, multiple alarms are often installed within the same hoisting zone, which can easily lead to multiple devices sounding simultaneously, or false alarms due to equipment malfunctions, resulting in continuous alarms and severely interfering with the warning effect.

[0070] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0071] Example 1

[0072] This embodiment provides a hook device, such as Figure 1 As shown, the hook has a hook seat 10, and a hook 20 is connected below the hook seat 10. The hook seat 10 is used to connect the tower crane's ropes and to suspend building materials through the hook 20.

[0073] In this embodiment, the hook 20 is a hook, and the hook base 10 includes a housing and a pulley disposed in the housing. That is, the hook base 10 is a housing with a movable pulley assembly installed. The housing can be in a near-rectangular shape. The rope is connected to the movable pulley assembly in the hook base 10 to realize the lifting operation of the hook 20.

[0074] like Figure 1 As shown, the hook in this embodiment has an alarm component 30, which is installed in the housing of the hook seat 10, and at least a portion of the alarm component 30 is located on opposite sides of the pulley rotation axis. The alarm component 30 is connected to the tower crane monitoring subsystem. When the tower crane monitoring subsystem detects an abnormal situation near the hook, such as non-staff members or staff members approaching the hook at an inappropriate time, the alarm component 30 responds to the alarm signal from the tower crane monitoring subsystem and issues an alarm feedback, reminding them to leave.

[0075] like Figure 2As shown, the alarm component 30 is fixed to the hook base 10 and moves with the hook 20. With the hook 20 as the center, the tower crane monitoring subsystem only needs to detect the area near the hook 20 and issue a warning through a single alarm component 30, without affecting other lifting areas. The hook 20 can respond to alarm signals from the tower crane monitoring subsystem at any time. Only one alarm component 30 needs to move with the hook 20 to cover the entire lifting area, completely replacing the need to install numerous alarm devices in multiple fixed areas, significantly reducing equipment procurement and maintenance costs.

[0076] The entire system relies on a single alarm component with 30 sounds, fundamentally solving the problem of multiple alarm devices sounding simultaneously or false alarms in the hoisting area. This ensures clear, accurate, and effective alarm signals, reducing noise disturbances to construction site personnel. The alarm sound source comes directly from the moving hook itself, allowing for more precise targeting of specific locations where hoisting risks actually exist, providing a more direct and targeted warning to those violating regulations.

[0077] In this embodiment, the hook device is also equipped with a power module 40, which is electrically connected to the alarm component 30 to supply power to the alarm component 30.

[0078] Specifically, the alarm component 30 includes a signal receiving module 33, a controller module 34, and an alarm module. The signal receiving module 33 is wirelessly connected to the tower crane monitoring subsystem and is used to receive alarm signals from the tower crane monitoring subsystem; the controller module 34 is electrically connected to the signal receiving module 33 and is used to process the alarm signals; the alarm module is electrically connected to the controller module 34 and provides alarm feedback in response to the alarm signal commands processed by the controller module 34.

[0079] The power supply module 40 is electrically connected to the signal receiving module 33, the controller module 34 and the alarm module respectively, and is used to supply power to the signal receiving module 33, the controller module 34 and the alarm module.

[0080] Since the signal receiving module 33, controller module 34, and power supply module 40 are conventional devices in the field of electronic control, they will not be described in detail in this embodiment. The signal receiving module 33 can be a traditional wireless receiver, including but not limited to Bluetooth modules, Wi-Fi modules, etc. The controller module 34 can be a conventionally compatible controller, and the power supply module 40 can be a rechargeable lithium battery.

[0081] In one embodiment, the alarm component 30 may not include the signal receiving module 33 and the controller module 34. The signal receiving module 33 and the controller module 34 may be part of the tower crane monitoring subsystem. The alarm component 30 may also directly receive alarm signals from the tower crane monitoring subsystem and provide alarm feedback.

[0082] like Figure 3 and Figure 4 as well as Figure 7 As shown, the hook base 10 of this embodiment has a first housing 111 and a second housing 112. The first housing 111 and the second housing 112 are arranged in pairs on opposite sides of the body of the hook base 10. The signal receiving module 33 and the controller module 34 are disposed in the first housing 111, and the power supply module 40 is disposed in the second housing 112.

[0083] In this embodiment, the first housing 111 and the second housing 112 are compatible so that the center of gravity of the hook seat 10 is located inside the body of the hook seat 10, thereby ensuring the balance of the hook seat 10. Specifically, the first housing 111 and the second housing 112 can be weight-compatible; that is, after the first housing 111 and the second housing 112 are installed internally, their combined weight can ensure that the hook seat 10 is in a balanced state.

[0084] In this embodiment, the first housing 111 and the second housing 112 are used to install and fix the internal modules of the alarm component 30. Considering that using one housing to install on the hook seat 10 would inevitably cause the hook seat 10 to be unbalanced due to the weight of the alarm component 30, resulting in the hook 20 tilting and affecting the hoisting operation, this embodiment uses two housings with matching weights.

[0085] Of course, the first housing 111 and the second housing 112 can also be set into corresponding shapes to ensure the balance of the hook seat 10.

[0086] Please see Figure 4 The first housing 111 and the second housing 112 are located on opposite sides of the hook base 10. Since the power module 40 is relatively heavy, it can be installed separately in the second housing 112, while other modules are integrated into the first housing 111. The first housing 111 and the second housing 112 are fixedly connected by a connecting rod assembly 120, and the internal components of the first housing 111 and the second housing 112 are connected by wires.

[0087] Preferably, the first enclosure 111 and the second enclosure 112 each have a door for easy access and maintenance. The power module 40 uses a removable battery to facilitate replacement and meet the long-term power supply requirements of the alarm component 30.

[0088] It is worth mentioning that in this embodiment, the first housing 111 and the second housing 112 are distributed on both sides of the pulley axis in the hook seat 10 body. That is, the line connecting the first housing 111 and the second housing 112 is perpendicular to the pulley axis. This can reduce the influence of the weight of the first housing 111 and the second housing 112 on the hook 20, prevent the hook 20 from tilting along its side, and ensure that the lifting operation of the hook 20 is carried out smoothly.

[0089] In this embodiment, as Figure 5 and Figure 6 As shown, the linkage assembly 120 connecting the first housing 111 and the second housing 112 includes a first connecting rod 121 and a second connecting rod 122. The two ends of the first connecting rod 121 and the second connecting rod 122 are respectively connected to and fixed to the first housing 111 and the second housing 112. The first connecting rod 121 and the second connecting rod 122 are each disposed on opposite sides of the hook base 10 body and connected to the first housing 111 and the second housing 112 to form a ring structure that surrounds the hook base 10 body. In this way, the entire alarm assembly 30 and the power module 40 are arranged around the outside of the hook base 10 body, increasing the connection area between the first housing 111 and the second housing 112 and the hook base 10 body, thereby improving the connection stability of the alarm assembly 30 and the power module 40 with the hook base 10.

[0090] In one embodiment, the first housing 111, the second housing 112, the first connecting rod 121, and the second connecting rod 122 are respectively connected to the hook seat 10 body by anti-loosening bolts, and can also be connected to each other by anti-loosening bolts, or partially by welding.

[0091] Furthermore, a fall protection safety rope is provided between the first housing 111 or the second housing 112 and the hook seat 10 body. Even if the connection between the first housing 111 or the second housing 112 becomes loose, or if the connection of the first housing 111 or the second housing 112 is damaged due to a collision, the fall protection safety rope can ensure that the first housing 111 or the second housing 112 will not fall off the hook seat 10 body, preventing the internal modules from being damaged.

[0092] In one embodiment, the two ends of the fall arrest safety rope are provided with U-shaped buckles, which are respectively fixed to the crossbeam of the hook seat 10 body and the lifting lugs of each box.

[0093] In one embodiment, the alarm module of the alarm component 30 may include an audible and visual alarm device; specifically, the alarm module may include a speaker 31.

[0094] like Figure 4 and Figure 5As shown, the speaker 31 is installed inside the first housing 111. The bottom of the first housing 111 has a horn for the sound of the internal speaker 31 to be emitted. The speaker 31 responds to the alarm signal command processed by the controller module 34 to make a voice prompt, or directly receives the alarm signal from the tower crane monitoring subsystem and issues an alarm to remind the unauthorized personnel to leave.

[0095] The alarm module can also be a light strip assembly 32, which is respectively disposed on the first connecting rod 121 and the second connecting rod 122 and arranged along the extension direction of the first connecting rod 121 or the second connecting rod 122. The light strip assembly 32 flashes in response to the alarm signal command processed by the controller module 34, or directly receives the alarm signal flashing from the tower crane monitoring subsystem to achieve the warning effect.

[0096] It is worth mentioning that this embodiment includes a light strip assembly 32. The elongated light is not only easy to observe, but it can also be distinguished from the worker's helmet. Since the tower crane monitoring subsystem's camera 50 identifies the hook and workers from a height, and generally, workers' helmets are round and colored, the elongated light is clearly distinguishable from the helmet, preventing the tower crane monitoring subsystem from mistaking the flashing light for a worker and causing the monitoring system to malfunction.

[0097] In this embodiment, the warning light strip assembly 32 is set into a long strip shape, which is clearly different from the traditional alarm light. This helps to improve the recognition efficiency of the tower crane monitoring subsystem and improve the accuracy of intelligent control.

[0098] Furthermore, the light strip assembly 32 in this embodiment includes a first light strip 321 and a second light strip 322. The first light strip 321 has two sets, which are respectively disposed on the upper surfaces of the first connecting rod 121 and the second connecting rod 122, for identification by the tower crane monitoring subsystem or for observation by the tower crane operator.

[0099] like Figure 5 As shown, in one embodiment, the first light strip 321 is disposed on the top of the first housing 111 or the second housing 112 so that it can be observed by the tower crane operator. The first light strip 321 can be captured by a camera 50 mounted on the tower crane, and the tower crane operator can observe the first light strip 321 through a display device in the tower crane control room.

[0100] Preferably, the first light strip 321 uses a green light, and the flashing green light can be distinguished from the safety helmet, avoiding incorrect identification by the camera 50.

[0101] The second light strip 322 is also set in two sets, respectively set on the lower surface of the first connecting rod 121 and the second connecting rod 122, for observation by ground personnel in the hoisting area, and to remind non-staff members to leave in conjunction with the speaker 31.

[0102] In one embodiment, the first light strip 321 is a single light strip. Generally, since green helmets are not commonly used on construction sites, the first light strip 321 in this embodiment can be green to distinguish it from the color of the safety helmet and prevent misjudgment by the tower crane monitoring subsystem. The second light strip 322 can be multiple light groups using orange light to achieve a warning effect.

[0103] like Figure 5 As shown, a wiring conduit 123 is also provided on the upper surface of the first connecting rod 121 and the second connecting rod 122. The wiring conduit 123 extends from the first housing 111 to the second housing 112 and is used to install the wires of the internal modules of the first housing 111 and the second housing 112, so as to protect the wires between the first housing 111 and the second housing 112 and realize orderly wiring.

[0104] Example 2

[0105] like Figure 2 As shown, this embodiment provides a tower crane device, which includes a tower crane body 70 and a hook device as mentioned in Embodiment 1 above, wherein the hook is suspended from the tower arm of the tower crane body 70 by a rope.

[0106] The tower crane device in this embodiment has the hook device mentioned in Embodiment 1 above, and therefore also has all the advantages mentioned above. This embodiment will not repeat them here.

[0107] Example 3

[0108] This embodiment provides a tower crane control system, which has a tower crane monitoring subsystem. This subsystem is used in the hook device mentioned in Embodiment 1 or the tower crane device in Embodiment 2 to monitor the surrounding environment during the hook lifting process and ensure lifting safety.

[0109] The subsystem is equipped with the hook device mentioned in Embodiment 1 above, and the subsystem has a camera 50 installed on the tower arm of the tower crane device. The camera 50 is located above the hook 20 and collects image information around the hook 20 from a top-down angle.

[0110] The camera 50 uses an AI smart camera, but it can also be any of the following: a regular camera, a binocular recognition camera, an IPC camera, a depth camera, or an infrared camera.

[0111] The tower crane monitoring subsystem is equipped with a processing device 60, which is connected to a camera 50. The processing device 60 receives the image information collected by the camera 50 and sends an alarm signal by determining that the target object has entered a preset range centered on the hook 20.

[0112] The preset range centered on the hook 20 can be a planar range where the hook 20 is located, for example, a circular planar range with a radius of 3-10 meters centered on the hook 20; or it can be a three-dimensional range around the hook 20, including the upper and lower areas of the hook 20, for example, a spherical range with a radius of 3-10 meters centered on the hook 20.

[0113] The processing device 60 can be a server installed on the tower crane or a remote server. Preferably, the processing device 60 is located in the control room of the tower crane.

[0114] In this embodiment, the processing device 60 is equipped with a training model. After the camera 50 acquires image information, it sends it to the processing device 60. The processing device 60 inputs the image information into the training model and obtains the processing result through the training model.

[0115] like Figure 8 As shown, in one embodiment, the training model includes at least a preprocessing module 61, a training module 62, and a detection module 63. The preprocessing module 61 performs image cropping and annotation, the training module 62 generates a recognition model based on historical data, and the detection module 63 analyzes the input from the camera 50 in real time.

[0116] The workflow for training this model is as follows:

[0117] S11, the preprocessing module 61 acquires a set of historical images of the tower crane construction site and labels the hooks 20 and human objects therein, including human objects wearing safety helmets.

[0118] In this embodiment, the annotation process includes a human body bounding box annotation process and a classification annotation process. The human body bounding box annotation process involves outlining the area covered by the human body in the original image, where the bounding box should include the entire part of the human body. Further, the classification annotation process involves cropping the human body bounding box area to obtain a human body bounding box image, and then classifying the human body bounding box image according to whether it is a target object.

[0119] S12, the training module 62 constructs a detection network and a classification network. Based on the labeled historical image set, the detection network and the classification network are trained respectively to obtain a detection model and a classification model respectively. The detection model is used to identify human objects and hooks in the image, and the classification model is used to distinguish target objects in the image.

[0120] The target group here can refer to non-workers, such as workers other than those engaged in rigging operations. These workers are prohibited from entering the hoisting area, so it is necessary to identify them.

[0121] The detection network in this embodiment is built on the YOLOv5 algorithm, and the classification network can adopt the Mobilenetv3 algorithm model. The algorithm networks for training the model in this embodiment are all implemented using known conventional methods in the art, so this embodiment will not elaborate on them.

[0122] S13, the detection module 63 acquires the current image captured by the camera 50, detects human objects and hooks 20 in the current image through the detection model, and identifies target objects in the human objects through the classification model.

[0123] In this embodiment, the detection model identifies human objects based on the shape and color of targets in the current image. For example, a helmet appears circular and colored from a top-down view, so the detection model identifies the target as a human object. The classification model identifies target objects based on the color of the human object. For example, the safety helmet of a slinger is red, while the safety helmets of other personnel are yellow; the classification model identifies the yellow safety helmet as the target object.

[0124] The processing device 60 determines the target area based on the hook 20 in the current image as the center. This target area is the safe area around the hook 20. The coordinates of the target object are obtained through the calculation system, and it is determined whether the target object is in the target area. If so, an alarm signal is sent.

[0125] The tower crane monitoring subsystem of this embodiment can effectively detect the personnel situation in the area centered on the hook 20 in real time. When non-staff enter the safe range of the hook 20, the tower crane monitoring subsystem immediately issues an alarm through the alarm component 30 on the hook 20, prompting the relevant personnel to leave immediately. While realizing intelligent monitoring, the system also has all the advantages described in the above embodiment.

[0126] In this embodiment, the first light strip 321, as described above, is disposed on the upper surface of the connecting rod assembly 120 and is used to be identified by the tower crane monitoring subsystem. The camera 50 in this embodiment can be used to acquire image information of the first light strip 321.

[0127] In alarm state, the first light bar 321 receives an alarm signal and flashes. This state is captured by the camera 50 and the information is transmitted to the processing device 60. The flashing signal of the first light bar 321 can be transmitted to the processing device 60 as a positive feedback signal so that the processing device 60 can further determine that the alarm state is in effect.

[0128] The processing unit 60 can also send the feedback signal to an early warning device in the tower crane control room or on the remote control platform 80. The early warning device responds to the alarm signal and the feedback signal by issuing an alarm. The early warning device can be a display screen or an audible and visual alarm device, etc., for the operator to observe and be alerted.

[0129] Furthermore, the processing device 60 of the tower crane monitoring subsystem in this embodiment also has a height measurement module, which is used to obtain the height of the hook 20 from the ground; the processing device 60 obtains the current height of the hook 20, and determines whether the hook is at the target height based on the current height of the hook 20. If so, and when it is determined that the target object is in the target area, an alarm signal is sent.

[0130] In this embodiment, the height measurement module is installed on the tower crane body 70. It can be an intelligent camera and calculation software, such as using the intelligent camera 50 to calculate the current height of the hook 20. Alternatively, the height measurement module can be a hook rope winding encoder, which is installed on the tower crane body 70 and works in conjunction with the hook rope. The winding encoder determines the height of the hook 20 by calculating the winding length of the rope.

[0131] Specifically, the tower crane monitoring subsystem can determine the height of the hook 20 through the camera 50 or the encoder of the rope. Depending on the on-site operation, different hoisting zones can be set for different floors. Since the height of each hoisting zone is different, the alarm function will only be activated when the hook moves up and down and reaches the height range corresponding to each hoisting zone.

[0132] With this setting, a preset height condition for triggering the alarm component 30 can be set. The alarm component 30 moves and operates with the hook. Once the alarm component 30 reaches the height range, it can immediately issue an alarm, eliminating the drawback of existing alarm devices that cannot be activated because the trigger height has not been reached.

[0133] Example 4

[0134] like Figure 9 As shown, this embodiment provides a tower crane control system, which has a tower crane remote control subsystem. The subsystem includes the tower crane device as described above. The tower crane body 70 of the tower crane device has an image acquisition module and a tower crane control module 71. The image acquisition module may include the camera 50 as described above. The tower crane control module 71 is used to control the lifting operation of the tower crane device.

[0135] This embodiment includes a remote control platform 80, which is installed on the ground away from the tower crane device. The remote control platform 80 is connected to the image acquisition module and the tower crane control module 71 via a 4G or 5G communication network. The tower crane operator can obtain a visual image as if inside the tower crane device through the image acquisition module, and can control the tower crane control module 71 through the remote control platform 80 to realize remote control of the tower crane device.

[0136] In this embodiment, the remote control platform 80 adopts a ground control cabin, which can be set up to mimic the internal environment of the tower crane's control room. To ensure the integrity and safety of remote operation, the system integrates a holographic perception module to synchronously transmit three-dimensional operation data: visual information is collected by a 12-group heterogeneous camera array, including an AI visual sensor with deep learning capabilities and an ultra-low latency industrial-grade camera; auditory information is captured through an array of microphones to achieve 360° sound field capture; the vibration feedback system uses a distributed piezoelectric sensor network. The control switching system supports seamless transfer of authority between the tower crane's operating cabin and the ground control cabin. The switching process complies with the EN 13847 safety standard, ensuring operational continuity.

[0137] The system employs a three-layer network architecture to achieve high reliability: the main transmission channel uses an industrial-grade wireless bridge to ensure ultra-low latency of <100ms; dual backup links include a gigabit fiber optic ring network and a 5G slice network, achieving millisecond-level link switching through SDN technology. The intelligent monitoring module integrates three real-time data streams: the wire rope condition monitoring system uses a strain sensor array, the hazardous area identification system applies computer vision algorithms, and the collision avoidance system is based on UWB positioning and inertial navigation fusion data. All monitoring data is processed by edge computing nodes and synchronized to the remote control terminal via the OPC UA protocol.

[0138] Addressing the pain points of traditional tower crane operator cabins, such as harsh working environment, limited operating space, and insufficient accessibility, this system breaks through the physical limitations of traditional high-altitude operator cabins by constructing a ground control cabin independent of the tower crane device, providing operators with an ergonomic, temperature- and humidity-controlled operating environment.
