Description

Technical Field

[0001] This utility model relates to the field of crane technology, and more specifically, to a crane device. Background Technology

[0002] In industrial production, cranes are key material handling equipment. Traditionally, their operation relies primarily on operators in the crane's cab. From the cab, operators use their visual observation and experience to send commands to various actuators of the crane via control handles, buttons, and other devices, thereby controlling the crane's lifting, lowering, and translating movements to complete the lifting and transporting of goods.

[0003] In related technologies, because the operator's cab is located on the crane, the operator's field of vision is limited, resulting in blind spots. When the crane is lifting goods, especially large or heavy goods or in complex working environments, the operator cannot fully observe all the surrounding conditions of the crane, making it difficult to accurately judge the relative positional relationship between the hook, goods, and obstacles. This not only increases the difficulty of operation and easily leads to accidents such as collisions and scratches, but also may threaten the personal safety of the operator. Utility Model Content

[0004] The problem this invention addresses is how to reduce blind spots during crane operation.

[0005] To address the aforementioned problems, this utility model provides a crane device, comprising: a safety monitoring system and a display device connected to the safety monitoring system. The safety monitoring system includes multiple sensors, specifically including:

[0006] One or more of the sensors are mounted behind the hook of the crane device;

[0007] Multiple of the sensors are respectively installed above the boom of the crane device, below the boom, and on the side of the boom;

[0008] One or more of the sensors are mounted on the boom of the crane device;

[0009] Multiple sensors are installed around the operator's cab of the crane unit;

[0010] One or more sensors are installed at the start and end points of the crane track of the crane device.

[0011] The display device is installed in the cab of the crane and is used to display the images and data monitored by the multiple sensors in real time.

[0012] Optionally, the crane device further includes a travel position sensor installed on the traveling mechanism of the trolley and carriage of the crane device, and the travel position sensor is connected to the display device.

[0013] Optionally, the crane device further includes distance sensors installed at the start and end points of the crane track, and the distance sensors are connected to the display device.

[0014] Optionally, the crane device further includes vibration sensors installed on the traveling mechanisms of the trolley and carriage of the crane device, and the vibration sensors are connected to the display device.

[0015] Optionally, the crane device further includes a human body sensor installed above the operator's cab of the crane device, the human body sensor being connected to the display device.

[0016] Optionally, the crane device further includes ultrasonic sensors installed on both sides of the track and above the crane device, the ultrasonic sensors being connected to the display device.

[0017] Optionally, the crane device further includes an ambient temperature and humidity sensor installed on the crane device, and the ambient temperature and humidity sensor is connected to the display device.

[0018] Optionally, the crane device further includes a distance sensor mounted on the crane device, the distance sensor being connected to the display device.

[0019] Optionally, the crane device further includes an emergency stop unit connected to the power source of the crane device.

[0020] Optionally, the crane device further includes a storage module; the storage module is communicatively connected to the safety monitoring system.

[0021] This invention relates to a crane device that effectively solves the problem of blind spots during crane operation by installing multiple sensors at several key locations. In related technologies, operators in the cab often cannot directly observe the area behind the hook, creating blind spots that can easily lead to collisions between the hook and goods or obstacles. This invention addresses this by installing sensors behind the hook, which monitor the area in real time and transmit the image to a display device in the cab. This allows the operator to clearly see the area behind the hook, accurately determine the relative position of the hook to goods or obstacles, and adjust the hook's position and speed accordingly during operation, preventing collisions and scrapes, and effectively eliminating the blind spot behind the hook.

[0022] Furthermore, considering that the movement trajectory of the crane boom covers a large area when lifting goods, especially in complex working environments where various obstacles may exist around the boom, it is difficult for operators to fully observe all the conditions around the boom. This invention addresses this by installing sensors above, below, and on the sides of the boom. These sensors can monitor the environment around the boom from all angles. When the boom extends, retracts, rotates, or pitches, the sensors can promptly detect obstacles or other hazards around the boom and transmit the images to a display device. Operators can then accurately control the boom's movement based on these real-time images, preventing collisions with surrounding objects, ensuring the boom operates within a safe range, and reducing blind spots around the boom and during its movement.

[0023] Meanwhile, traditional cranes have blind spots around the operator's cab, preventing operators from fully understanding the surrounding environment and potentially posing safety hazards to nearby personnel or equipment. By installing multiple sensors around the cab to create a 360-degree surround-view monitoring system, real-time images from all directions around the cab can be captured. These images are transmitted to a display device inside the cab, allowing operators to have a comprehensive understanding of the surrounding environment, promptly identify nearby personnel, equipment, or other obstacles, thereby preventing collisions during operation, eliminating blind spots around the cab, and improving operational safety.

[0024] In summary, this utility model, by installing multiple sensors behind the hook, at various positions of the boom, and around the cab of the crane device, and transmitting the images and data monitored by the sensors to the display device in the cab in real time, enables the operator to have a comprehensive and intuitive understanding of various information about the crane and its surrounding environment. This effectively solves the problem of blind spots in the operation of traditional cranes, improves the safety and accuracy of crane operation, and reduces the probability of accidents.

[0033] Combination Figure 1 As shown, this utility model provides a crane device, including: a safety monitoring system and a display device connected to the safety monitoring system. The safety monitoring system includes multiple sensors, specifically including:

[0034] One or more of the sensors are mounted behind the hook of the crane device;

[0035] Multiple of the sensors are respectively installed above the boom of the crane device, below the boom, and on the side of the boom;

[0036] One or more of the sensors are mounted on the boom of the crane device;

[0037] Multiple sensors are installed around the operator's cab of the crane unit;

[0038] One or more sensors are installed at the start and end points of the crane track of the crane device.

[0039] The display device is installed in the cab of the crane and is used to display the images and data monitored by the multiple sensors in real time.

[0040] Specifically, the safety monitoring system includes multiple sensors installed at various key locations on the crane assembly to achieve comprehensive monitoring. These sensors may include cameras, among others. Specifically, a sensor is installed behind the hook. For example, when the operator is seated in the cab, the side of the hook furthest from the cab is considered "front," and the side of the hook closest to the cab is considered "rear." For instance, assuming the crane cab is on the left side, when the hook is in operation, the right side of the hook furthest from the cab is considered "front," and the left side is considered "rear." Installing a sensor behind the hook helps detect the operating status of the hook behind it during operation, including the presence of obstacles, thus better ensuring the safe operation of the crane. In this embodiment, the side of the hook furthest from the cab is considered "front," enabling monitoring of the area behind the hook to detect potential obstacles or hazards behind the hook and cargo, providing supplementary rear visibility for the operator and preventing collisions caused by blind spots. The crane boom features multi-directional sensors, with multiple sensors installed above, below, and to the sides of the boom. The top sensor monitors the space above the boom, detecting obstacles that may affect its safe movement. The bottom sensor detects obstacles or personnel below the boom, preventing accidents during descent. The side sensors monitor the sides of the boom, ensuring a safe distance between the boom and surrounding objects during swinging or movement, guaranteeing all-around safety during crane operations. Sensors mounted on the boom monitor the surrounding environment in real time, providing detailed information about the boom's operating area. This allows operators to fully understand the environment and precisely adjust the boom's position and direction, effectively preventing collisions. Sensors around the cab provide comprehensive coverage of blind spots, capturing dynamic information about people, vehicles, buildings, and other objects around the cab. This provides operators with accurate environmental information, ensuring they have a complete understanding of the crane's surroundings, enabling correct operational decisions and preventing accidents caused by blind spots.

[0041] Among crane types, common ones such as overhead cranes (bridge cranes) all have a defined track system. The track refers to the structure used to support and guide the crane's movement along a specific path. It typically consists of track beams and metal rails mounted on the beams. The crane's wheels roll on the rails, ensuring the crane can move smoothly along the predetermined route. Sensors at the start and end points of the track are installed to monitor the crane's position on the track. When the crane approaches the start or end point, they promptly alert the operator to prevent serious accidents such as derailment due to exceeding the travel range. They also monitor obstacles near the start and end points of the track, ensuring the crane's safe operation on the track.

[0042] The display device is installed in the crane operator's cab and connected to the safety monitoring system. In a preferred embodiment of this invention, multiple sensors in the safety monitoring system are wired to the display device.

[0043] The display device can show real-time images and data monitored by multiple sensors, including but not limited to real-time video images of the area behind the hook, all directions of the boom, the area around the cab, and the start and end points of the track, as well as other relevant data (such as distance, angle, speed, etc.). This allows operators to intuitively and comprehensively understand the situation of various key parts around the crane from inside the cab. It provides operators with a comprehensive, real-time monitoring platform, enabling them to accurately determine the relative positional relationship between the hook and the cargo or obstacles, thus making operation more efficient and effectively reducing operational difficulties and accident risks caused by blind spots, thereby improving the safety and efficiency of crane operation.

[0044] This embodiment achieves comprehensive, blind-spot-free monitoring of the crane's surrounding environment by installing sensors at multiple key locations on the crane. This significantly overcomes the blind spots inherent in traditional crane operation, ensuring safe crane operation in complex working environments. The display device shows the sensor-monitored images and data in real time, providing operators with accurate and timely on-site information. This allows for rapid response and precise judgment of the relative positions of the hook, cargo, and obstacles, leading to more accurate crane control and reduced accident rates. Operators gain a complete understanding of the crane's surroundings, reducing frequent stops for observation and waiting for assistance due to limited visibility. This makes crane operation smoother, more efficient, and improves work efficiency.

[0045] This invention relates to a crane device that effectively solves the problem of blind spots during crane operation by installing multiple sensors at several key locations. In related technologies, operators in the cab often cannot directly observe the area behind the hook, creating blind spots that can easily lead to collisions between the hook and goods or obstacles. This invention addresses this by installing sensors behind the hook, which monitor the area in real time and transmit the image to a display device in the cab. This allows the operator to clearly see the area behind the hook, accurately determine the relative position of the hook to goods or obstacles, and adjust the hook's position and speed accordingly during operation, preventing collisions and scrapes, and effectively eliminating the blind spot behind the hook.

[0046] Furthermore, considering that the movement trajectory of the crane boom covers a large area when lifting goods, especially in complex working environments where various obstacles may exist around the boom, it is difficult for operators to fully observe all the conditions around the boom. This invention addresses this by installing sensors above, below, and on the sides of the boom. These sensors can monitor the environment around the boom from all angles. When the boom extends, retracts, rotates, or pitches, the sensors can promptly detect obstacles or other hazards around the boom and transmit the images to a display device. Operators can then accurately control the boom's movement based on these real-time images, preventing collisions with surrounding objects, ensuring the boom operates within a safe range, and reducing blind spots around the boom and during its movement.

[0047] Meanwhile, traditional cranes have blind spots around the operator's cab, preventing operators from fully understanding the surrounding environment and potentially posing safety hazards to nearby personnel or equipment. By installing multiple sensors around the cab to create a 360-degree surround-view monitoring system, real-time images from all directions around the cab can be captured. These images are transmitted to a display device inside the cab, allowing operators to have a comprehensive understanding of the surrounding environment, promptly identify nearby personnel, equipment, or other obstacles, thereby preventing collisions during operation, eliminating blind spots around the cab, and improving operational safety.

[0048] In summary, this utility model, by installing multiple sensors behind the hook, at various positions of the boom, and around the cab of the crane device, and transmitting the images and data monitored by the sensors to the display device in the cab in real time, enables the operator to have a comprehensive and intuitive understanding of various information about the crane and its surrounding environment. This effectively solves the problem of blind spots in the operation of traditional cranes, improves the safety and accuracy of crane operation, and reduces the probability of accidents.

[0049] Optionally, the crane device further includes a travel position sensor installed on the traveling mechanism of the trolley and carriage of the crane device, and the travel position sensor is connected to the display device.

[0050] Specifically, the trolley travel position sensor is installed on the crane's trolley travel mechanism, which typically refers to the part of the crane that moves long distances on the track. The sensor can detect changes in the trolley's position on the track in real time. This sensor is connected to a display device in the operator's cab via a wired data connection, such as a transmission line, ensuring that travel position information is promptly transmitted to the operator.

[0051] The trolley position sensor is installed on the crane trolley's traveling mechanism, which is mainly responsible for the lateral or longitudinal movement of the hook on the boom, used to adjust the hook's position to accurately align with the goods or work point. Similarly, the trolley position sensor is connected to a display device, allowing operators to monitor the trolley's position in real time; effectively solving the blind spot problem that exists in traditional crane operation.

[0052] The travel position sensor can be a camera, which captures images to determine the positions of the main vehicle and the auxiliary vehicle. Alternatively, it can be a proximity switch sensor. Multiple main vehicle travel position sensors are spaced apart along the main vehicle's movement track, each sensor corresponding to a main vehicle position. When the main vehicle moves along the track and reaches the sensing position of a main vehicle travel position sensor, its position can be determined by the sensor number displayed on the display device. Similarly, multiple auxiliary vehicle travel position sensors can be spaced apart along the auxiliary vehicle's travel path, and the auxiliary vehicle's position can be determined based on the detection of these sensors.

[0053] In this optional embodiment, the trolley and crane position sensors can accurately monitor the position of the traveling mechanism on the track or boom, and transmit this position information in real time as data or video to the display device in the operator's cab. The operator can intuitively see the trolley's position on the track and the crane's position on the boom through the display device.

[0054] For example, when cranes operate in complex environments, such as areas where multiple cranes work together, near buildings, or in areas with obstacles, operators need to precisely control the movement of the trolley and crane to avoid collisions with other objects. Real-time position information provided by the travel position sensor helps operators determine the distance between the crane and surrounding objects, precisely control the travel speed and direction, make more accurate operational decisions, and improve the safety and accuracy of operations.

[0055] In another example, such as in operations that require frequent adjustments to the hook position, like when precisely positioning and lifting goods, the trolley's position sensor can provide real-time feedback on the trolley's position. Operators can quickly adjust the trolley's movement based on the specific location and requirements of the goods, ensuring the hook accurately reaches the target position, reducing unnecessary repeated adjustments, and improving operational efficiency.

[0056] Furthermore, in the event of a collision or other accident involving the crane, the travel position data recorded by the travel position sensors can serve as crucial evidence for accident analysis. By examining the changes in the travel positions of the trolley and crane before the accident, the cause of the accident can be identified more accurately, providing strong data support for improving operational procedures and safety management measures.

[0057] Optionally, the crane device further includes distance sensors installed at the start and end points of the crane track, and the distance sensors are connected to the display device.

[0058] Specifically, distance sensors are installed at the start and end points of the crane track. These sensors are connected to the display device in the cab via data transmission lines to ensure that the measured distance information can be transmitted to the display device in front of the operator in real time.

[0059] In some embodiments, distance sensors are typically installed near both ends of the track, and their measurement range covers the area where the crane travels on the track, enabling accurate measurement of the distance between the crane and the start or end point of the track. The distance sensors can measure the distance between the crane and the start or end point of the track in real time and display this distance information visually on a display device in the operator's cab, in numerical, video, or other formats. The operator can monitor the crane's position on the track and the distance between the crane and the ends of the track at any time.

[0060] For example, when the crane is traveling on the track, the distance sensor can accurately detect the distance between the crane and the start or end point of the track. When the distance approaches the preset safety threshold, it can promptly issue a warning signal to the operator, reminding the operator to slow down or stop the crane, preventing serious accidents such as derailment due to exceeding the travel range, and ensuring the safe operation of the crane on the track.

[0061] For example, in complex working environments, such as when multiple cranes are operating together on the same or adjacent tracks, the distance information provided by the distance measuring sensor can help operators accurately determine the crane's position on the track, avoiding collisions with other cranes or obstacles on the track. It also prevents the crane from contacting other equipment or buildings when approaching the end of the track, improving operational safety and reliability. Furthermore, for operational scenarios requiring precise scheduling and planning, such as in ports and logistics centers, the distance measuring sensor can provide operators and the scheduling system with accurate crane location information, facilitating the rational arrangement of crane tasks, travel routes, and work sequences, thereby improving overall operational efficiency and equipment utilization.

[0062] Meanwhile, the distance data recorded by the distance measuring sensors can be stored as part of the crane's operating data. In the event of a collision or other accident, this distance data can serve as an important basis for accident analysis. By examining the changes in the distance between the crane and the start and end points of the track before the accident, the cause of the accident can be identified more accurately, providing strong data support for improving operating procedures and safety management measures.

[0063] In this embodiment, the distance measuring sensor, along with the travel position sensor and other sensors in the safety monitoring system, are combined to construct a more comprehensive crane safety monitoring network. For example, when the crane approaches the end of the track, the distance measuring sensor and the sensor at the end of the track work together to issue an early warning signal, reminding the operator to slow down or stop the crane in time to prevent derailment or collision with other equipment. Simultaneously, this sensor data can also be integrated with the crane's control system to achieve automated control functions, such as automatically stopping travel or adjusting speed when a preset distance is reached, further improving the safety and intelligence of crane operation.

[0064] Optionally, the crane device further includes vibration sensors installed on the traveling mechanisms of the trolley and carriage of the crane device, and the vibration sensors are connected to the display device.

[0065] Specifically, vibration sensors are installed on the crane's trolley and crane travel mechanisms, respectively, and can be connected to a display device in the operator's cab via wired connection. In optional embodiments of this invention, the vibration sensors detect vibrations based on piezoelectric effects, strain effects, or inertial principles. When the trolley or crane travel mechanism vibrates, the sensitive element inside the sensor generates a corresponding change in electrical signal. For example, a piezoelectric vibration sensor utilizes the piezoelectric effect of piezoelectric materials such as crystals or ceramics to convert the mechanical energy caused by vibration into an electrical signal. By measuring parameters such as the amplitude and frequency of the electrical signal, the intensity and characteristics of the vibration can be accurately reflected.

[0066] Vibration sensors can monitor the vibration of the trolley and carriage traveling mechanisms in real time, converting the vibration signals into digital or analog signals and transmitting them to a display device. On the display device, operators can intuitively see key parameters such as the vibration waveform, amplitude, and frequency of the traveling mechanism. For example, the vibration change over time can be displayed as a curve, or the current vibration intensity level can be displayed digitally.

[0067] In a preferred embodiment of this invention, long-term recording of vibration data can be used to evaluate the crane's operating status. Analyzing the trend of vibration changes over time helps to understand the wear and performance changes of the traveling mechanism. Furthermore, based on the vibration data, the crane's operating parameters can be optimized. For example, if excessive vibration is found when the trolley is lifting heavy objects, it may be due to excessive lifting speed or unstable braking process. By adjusting the lifting and braking parameters, vibration can be reduced, improving the stability and safety of the crane's operation.

[0068] In this optional embodiment, vibration sensors provide crucial safety assurance for crane operation. Abnormal vibrations can lead to serious consequences such as structural fatigue, component damage, or even overall instability of the crane. By monitoring vibrations in real time, potential hazards can be detected before they occur, preventing accidents caused by vibration. For example, under special operating conditions such as strong winds or earthquakes, cranes may experience abnormal vibrations. Vibration sensors can promptly reflect this situation, enabling operators to take emergency measures, such as stopping operations and evacuating personnel, to avoid potential major accidents.

[0069] Optionally, the crane device further includes a human body sensor installed above the operator's cab of the crane device, the human body sensor being connected to the display device.

[0070] Specifically, the human body sensor is installed above the crane operator's cab and can be connected to a display device inside the cab via a wired connection. This installation position effectively monitors the activity of personnel in the space surrounding the cab, ensuring that operators can promptly know whether anyone is approaching or in a dangerous area during crane operation. The human body sensor detects human activity based on technologies such as infrared, microwave, or ultrasonic waves. When a person enters its monitoring range, the sensor detects changes in the infrared radiation, microwave reflection, or ultrasonic wave reflection signals emitted by the human body, thereby determining the presence of someone and issuing a corresponding signal.

[0071] The primary function of a human body sensor is to provide safety warnings. When a person enters the sensing area above the operator's cab, the sensor immediately transmits a signal to the display device, alerting the operator to the presence of a person nearby. This is particularly important during crane operation, as operators may not be able to directly observe the movements of people around them due to blind spots or other reasons. Through the warning from the human body sensor, operators can take timely measures to avoid safety accidents caused by people approaching, ensuring their personal safety. In another example, people may accidentally enter dangerous areas of the crane, such as the boom's range of motion or the trolley's travel path. The human body sensor can detect and alert the operator when people enter these areas, thus preventing collisions or crushing accidents caused by misoperation. For example, when a person is in the trolley's travel path, the sensor will issue an alarm, reminding the operator to stop the trolley or take other safety measures to avoid injury; effectively solving the blind spot problem in traditional crane operation.

[0072] In this optional embodiment, when the human body sensor detects personnel in a dangerous area, it can trigger the emergency stop system, causing the crane to stop immediately and ensuring personnel safety. Simultaneously, it can also feed back the detected personnel activity information to the safety monitoring system for comprehensive analysis and decision-making by operators and managers. By monitoring the activity of personnel around the cab in real time, the human body sensor can help operators better plan and execute lifting tasks. While ensuring safety, operators can adjust the work process based on the distribution of personnel, improving operational efficiency. For example, lifting operations can be performed when there are fewer personnel or in areas avoiding densely populated areas, reducing work interruptions or delays caused by personnel interference.

[0073] Furthermore, human body sensors can record data such as the time and frequency of personnel entering the sensing area. This data can be stored in the crane's storage module, and it also allows for understanding the patterns of personnel activity around the crane, providing a basis for optimizing crane operation procedures and safety management measures. For example, if it is found that personnel frequently enter dangerous areas within a certain time period, targeted safety training can be strengthened or operating times can be adjusted to reduce potential safety risks. The application of human body sensors in crane equipment provides operators with an effective means of personnel monitoring, significantly improving the safety and reliability of crane operation. Through timely warnings and coordination with other safety systems, it effectively prevents accidents caused by personnel accidentally entering dangerous areas, ensuring the safety of personnel and the normal operation of equipment.

[0074] Optionally, the crane device further includes ultrasonic sensors installed on both sides of the track and above the crane device, the ultrasonic sensors being connected to the display device.

[0075] Specifically, ultrasonic sensors are installed on both sides and above the crane rails and can be connected to a display device in the operator's cab via wired connections. The sensors on the sides of the rails are typically mounted on the rail posts or beams at a certain height to ensure coverage of a large area on both sides of the rails. The sensors in the overhead space are installed at appropriate locations on top of the crane or above the rails to monitor for obstacles in the area above the rails.

[0076] Ultrasonic sensors typically have a measurement range of several centimeters to several meters, meeting the needs of cranes for detecting obstacles at close range near the track. For example, some ultrasonic sensors have a measurement range of 5-500cm, enabling them to accurately detect obstacles such as buildings, other equipment, or stacked goods in the space on both sides and above the track. Ultrasonic sensors offer high measurement accuracy, usually within ±1-3mm, allowing them to accurately measure the distance between the crane and obstacles. This provides operators with precise distance information, helping them better plan the crane's operating path and actions. Ultrasonic sensors can quickly transmit and receive ultrasonic signals and rapidly calculate distance information.

[0077] In this optional embodiment, the ultrasonic sensor can monitor obstacles on both sides and above the track in real time and display the distance information in digital or graphical form on a display device in the cab. For example, different colored icons can represent obstacles within different distance ranges, or the distance to obstacles can be displayed digitally in real time, allowing the operator to intuitively understand the real-time conditions of the crane's surroundings and avoiding the problem of blind spots in the operator's field of vision.

[0078] Furthermore, the data collected by ultrasonic sensors can be stored in the crane's storage module for subsequent data analysis and accident investigation. Analysis of historical data allows for understanding the crane's operation under different working environments, identifying potential safety hazards and operational problems, and providing a basis for optimizing crane design and operating procedures. In the event of a collision or other accident, the distance data recorded by the ultrasonic sensors can help determine the cause of the accident, such as whether it was due to a sudden obstacle, improper operation, or sensor malfunction, allowing for appropriate corrective measures to prevent similar accidents from recurring.

[0079] Optionally, the crane device further includes an ambient temperature and humidity sensor installed on the crane device, and the ambient temperature and humidity sensor is connected to the display device.

[0080] Specifically, an ambient temperature and humidity sensor is installed on the crane to accurately reflect the temperature and humidity conditions of the crane's working environment. It is connected to a display device in the operator's cab via a wired connection to ensure that temperature and humidity data are transmitted to the operator in real time.

[0081] In this optional embodiment, the ambient temperature and humidity sensor can monitor the temperature and humidity of the environment around the crane in real time and transmit the data to a display device. The operator can intuitively view the current ambient temperature and humidity values ​​in the cab, such as displaying the temperature (e.g., 25.3°C) and humidity (e.g., 45% RH) in precise digital form.

[0082] In addition, the data collected by the ambient temperature and humidity sensors can be stored in the crane's storage module for subsequent data analysis. By analyzing historical temperature and humidity data, operators can understand the changes in environmental conditions faced by the crane in different seasons and working locations, providing a basis for developing reasonable equipment maintenance plans, work scheduling schemes, and safe operating procedures. For example, in some regions with high temperatures and humidity in summer, historical data can be used to prepare equipment for high temperature and moisture protection in advance; while in the cold winter, preheating and antifreeze maintenance can be arranged in advance. Furthermore, in the event of equipment failure or safety accidents, temperature and humidity data can also serve as a reference factor in accident investigations, helping to determine whether the cause of the accident is related to environmental conditions.

[0083] Optionally, the crane device further includes a distance sensor mounted on the crane device, the distance sensor being connected to the display device.

[0084] Specifically, distance sensors are installed on the crane, typically at key locations such as the hook, trolley, or overhead crane travel mechanism. They connect to a display device in the operator's cab via wired or wireless communication, ensuring real-time transmission of distance data to the operator. The distance sensors measure the distances between the crane and surrounding objects in real time, such as the distance between the hook and cargo / obstacles, and the distance between the crane and surrounding buildings / other equipment. This distance information is then displayed digitally on the operator's cab display. For example, it might accurately show a distance of 0.5 meters between the hook and the top of the cargo, or 2.3 meters between the hook and an obstacle ahead. The display device can also be set with different colors or icons to represent objects within different distance ranges, allowing operators to quickly identify potentially dangerous distances. For instance, when the distance is less than 1 meter, the distance value is displayed in red to alert the operator to safety.

[0085] For example, when lifting goods, distance sensors can accurately measure the distance between the hook and the cargo, helping operators precisely control the lifting and lowering height of the hook. This is especially important when lifting large, heavy, or irregularly shaped goods, effectively preventing damage to the cargo or lifting failures caused by collisions between the hook and the cargo or incomplete hook descent. For instance, when lifting containers in a port, distance sensors ensure that the hook is accurately inserted into the container's lifting hole, improving lifting efficiency and safety. Simultaneously, by measuring the distance between the hook and the bottom of the cargo, collisions between the cargo and the ground or other objects during lifting can be prevented.

[0086] In addition, the data collected by the distance sensors can be stored in the crane's storage module for subsequent data analysis. By analyzing historical distance data, it is possible to understand the crane's operation under different working environments, identify potential safety hazards and operational problems, and provide a basis for optimizing the crane's design and operating procedures.

[0087] For example, by analyzing distance data, it can be discovered that cranes frequently fly too close together in certain areas, allowing for optimization and adjustment of the work process or equipment layout in those areas. In the event of a collision or other accident, distance data recorded by distance sensors can help determine the cause of the accident, such as whether it was caused by a sudden obstacle, improper operation, or sensor malfunction, thus enabling appropriate corrective measures to be taken to prevent similar accidents from recurring.

[0088] Optional, combined Figure 2 As shown, the crane device also includes an emergency stop unit, which is connected to the power source of the crane device.

[0089] Specifically, the emergency stop unit includes multiple emergency stop buttons installed in easily accessible locations both inside and outside the crane operator's cab. Emergency stop buttons inside the cab are typically located near the control panel for quick operation by the operator in emergencies. External emergency stop buttons can be installed at the crane's entrance, at appropriate locations on the trolley and crane traveling mechanisms, etc., ensuring that on-site personnel can also trigger them promptly upon discovering a hazard. The emergency stop unit is connected to the crane's power source via a wired connection to ensure that stop commands can be quickly transmitted to the entire crane control system in an emergency.

[0090] An emergency stop unit can be used to immediately cut off the crane's power source in emergency situations, instantly stopping all crane movements (such as hook lifting and lowering, and trolley and crane movement). For example, when operators discover a serious crane malfunction, such as brake system failure or hook detachment risk, or when on-site personnel discover someone has mistakenly entered the crane's dangerous area and a collision is imminent, pressing the emergency stop button will stop the crane in a very short time, preventing an accident from occurring or escalating. The emergency stop unit provides a critical safety barrier for crane operation. It can handle various emergencies, such as equipment failure, human error, and abnormal swaying caused by severe weather. For example, in strong winds, if the crane's windproof device fails, the crane may slide uncontrollably. Pressing the emergency stop button will quickly stop the crane's operation, preventing it from colliding with adjacent equipment or buildings and ensuring the safety of equipment and personnel.

[0091] For example, when the emergency stop button is pressed, the emergency stop unit sends a signal to the safety monitoring system. Upon receiving the signal, the safety monitoring system displays the emergency stop status information on the display device, alerting operators and site managers that the crane is in an emergency stop state. Simultaneously, the system may trigger an audible and visual alarm to warn surrounding personnel of potential danger. For instance, in a factory workshop, when a crane stops due to an emergency stop, the alarm sound can alert other workers to stay away from the crane, preventing potential hazards when the equipment resumes operation. Furthermore, when the emergency stop unit is triggered, the safety monitoring system can record various data at the time of the emergency stop, such as the crane's operating speed, position, and hook load. This data is crucial for post-accident analysis of the cause of the accident. Additionally, the safety monitoring system can automatically trigger the emergency stop unit according to preset logic in certain serious faults or dangerous situations, further improving crane safety. For example, when the crane's overload sensor detects severe overload, the safety monitoring system can immediately activate the emergency stop unit to stop the crane's operation, preventing major accidents such as crane overturning due to overload.

[0092] Optional, combined Figure 2 As shown, the crane device also includes a storage module; the storage module is communicatively connected to the safety monitoring system.

[0093] Specifically, the storage module is connected to the security monitoring system to receive data from various sensors (such as vibration sensors, ambient temperature and humidity sensors, distance sensors, etc.) and display devices in the security monitoring system, ensuring that the data can be stored in real time and accurately.

[0094] The storage module is responsible for saving the raw data collected by various sensors during crane operation. This includes data such as vibration frequency and amplitude of the trolley and crane traveling mechanisms monitored by vibration sensors; temperature and humidity changes in the crane's working environment recorded by environmental temperature and humidity sensors; and distance information between the hook and goods or obstacles measured by distance sensors. This data is stored chronologically, forming a complete historical data sequence, providing a foundation for subsequent analysis and traceability.

[0095] In addition, the storage module stores crane operation records, such as operator instructions, crane operating status (start and stop times of lifting, lowering, and traveling actions), and hook load changes. These operation records clearly reflect the detailed operating procedures of the crane during each operation, helping to evaluate and analyze operator behavior and determine whether operations were performed correctly during accident investigations. The storage module also saves all alarm and event records generated by the crane, including various alarms triggered by the safety monitoring system (such as vibration exceeding limits, proximity alarms, abnormal temperature and humidity alarms, etc.) and important events such as the emergency stop unit being triggered. These records contain key information such as the time, type, duration of the alarm, and the corresponding crane operating status, which can be used to analyze the crane's safety status and the cause of failure.

[0096] In a preferred embodiment of this utility model, multiple sensors are installed at different positions on the crane and connected to a display device via wired connections such as RS485 or fiber optic cables to sense key information such as ambient temperature and humidity, distance to obstacles in front and behind, and the status of human beings within the working area.

[0097] Combination Figure 3 As shown, in a preferred embodiment of this invention, multiple wireless access points (APs) are installed within the work area, and the crane communicates with a switch or server via these APs. First, a switch and access processor are deployed in the factory's server room. The wireless access devices can be wireless APs, which, through the access processor, create a wireless local area network (WLAN) covering the entire factory area. The backend server is installed in the factory's server room and connected to the switch via a network cable. The operating equipment is installed inside the crane's electrical room, communicates with the crane's electrical control system, and is connected to the factory's WLAN. All sensors are installed on the crane and connected to the operating equipment via wired connections such as RS485 or fiber optic cables.

[0098] For example, combined Figure 3Specifically, multiple wireless access points (APs) are deployed throughout the factory area to provide wireless network access services to various devices and terminals. These APs communicate with various devices via wireless signals, and their distribution and number are determined based on the factory area, layout, and equipment distribution to ensure full wireless signal coverage and stable transmission. Cranes, as crucial heavy equipment within the factory, have their control units connected to the wireless network. They transmit real-time operating status data (such as position, speed, and load) to the backend server via wireless communication, and can also receive control commands from the backend, enabling remote monitoring and operation of the cranes. Operating equipment represents various production devices in operation within the factory area. They are wirelessly connected to the network and can upload their own operating data (such as temperature, pressure, and speed) to the backend, allowing management personnel to monitor equipment operation in real time, promptly identify anomalies, and perform maintenance. Multiple sensors are distributed at various key locations within the factory area to collect real-time environmental and equipment data, such as ambient temperature, humidity, gas concentration, and equipment vibration. These sensors transmit the collected data to display devices via wired or wireless transmission, enabling operators to monitor the operating environment and equipment status in real time, avoiding blind spots and achieving comprehensive monitoring. Handheld terminals are mobile devices provided to staff, connecting to the factory's network system via wireless network. Staff can use these terminals to flexibly access backend data, receive work instructions, query equipment information, and perform remote operations within the factory area, improving work efficiency and flexibility.

[0099] The factory's server room includes switches responsible for connecting the backend server and access processors, exchanging and forwarding data between them and the factory's wireless network. This ensures efficient and accurate data transmission across different network devices and subnets, while also managing and controlling data traffic to guarantee network stability and reliability. The backend server runs various industrial software and applications for data processing, storage, and analysis. It receives large amounts of real-time data from equipment and sensors within the factory, processes and stores this data, and extracts valuable information through data analysis, such as equipment failure prediction and production process optimization suggestions. It also provides managers with a visual data display interface for decision-making and management. The access processor performs preprocessing and protocol conversion on the received data, uniformly processing and converting heterogeneous data from different devices and sensors to meet the backend server's processing requirements, improving data processing efficiency and accuracy. The entire network architecture uses wireless access points (APs) to achieve wireless communication between factory equipment and the server room backend, enabling the factory to achieve real-time monitoring of equipment and the environment, centralized management and analysis of data, and intelligent control of the production process, thereby improving the factory's production efficiency, safety, and management level.

[0100] Combination Figure 4 As shown, in a preferred embodiment of this utility model, a terminal device is also included, which is a handheld terminal. It is rectangular in shape with an intuitive touchscreen on the front. Below the touchscreen is a voice area with a built-in high-sensitivity microphone and a clear, loud speaker for receiving voice commands from the operator and playing system voice feedback. Operating units are arranged on both sides, specifically including function buttons, operating joysticks, etc. Specifically, the left side of the terminal device, from top to bottom, has three selection knobs, six function buttons, and one operating joystick; the right side, from top to bottom, has one start button, one fault indicator light, one emergency stop knob, six function buttons, and one operating joystick. These buttons, knobs, and joysticks are used to operate the crane, and the success or failure of each operation can be displayed on the touchscreen. A signal enhancement antenna is provided at the top of the handheld terminal to ensure stable reception and transmission of wireless signals. In actual operation scenarios, operators hold the terminal device and use virtual buttons or icons on the touch screen for intuitive operation, monitoring the crane's operating status in real time; they can quickly issue operating commands through voice commands to improve work efficiency; in emergency situations, pressing the emergency stop knob can immediately cut off the crane's power supply to ensure safety.
