Description

Technical Field

[0001] This utility model belongs to the field of smart port technology, and more specifically, it relates to a multi-technology safety early warning device for port cranes. Background Technology

[0002] In the field of smart port technology, the development and application of a multi-technology safety early warning device for port cranes is of great significance for improving the safety and efficiency of port operations. Existing multi-technology safety early warning devices for port cranes mostly consist of a central processing unit, sensors, and communicators. These devices use various sensors to monitor the crane's operating status and changes in the surrounding environment in real time, transmitting the data to the central processing unit via wiring harnesses for calculation. The communication system then transmits the data from the sensors, enabling remote monitoring and fault diagnosis.

[0003] Existing application number CN20130202302016.9 discloses a method for dynamically adjusting the safety early warning threshold of crane structure monitoring. This method includes: statistically analyzing the location and probability of faults in the crane's metal structure based on design drawings and maintenance data records; performing tensile testing on the metal material to establish a mathematical model of the equivalent allowable stress of the metal material versus time, deriving the functional relationship K2=f(t); setting the theoretical maximum stress value K1 at each sensing point as the early warning value; and writing the functional relationship K2=f(t) and K1 at each sensing point into the business platform software system for dynamic threshold adjustment. This invention conducts tensile tests on metal materials from different years to obtain the functional relationship between the equivalent allowable stress K2 and time t, thereby more accurately and intelligently adjusting the dynamic threshold, and writing this into the software program for dynamic adjustment.

Detailed Implementation

[0050] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0051] Example 1:

[0052] As attached Figure 1 To be continued Figure 7 As shown:

[0053] This utility model provides a multi-technology safety early warning device for a dock crane, including a terminal computer 1;

[0054] ZibGee Wireless Communication 2, ZibGee Wireless Communication 2 is fixedly installed inside the dock;

[0055] Surveillance camera 3 is bolted to the bottom of the crane hoist trolley;

[0056] GPS high-precision positioning component 4, GPS high-precision positioning component 4 is fixedly installed inside the crane hoist trolley;

[0057] Multi-type sensor assembly 5 is fixedly installed inside the crane.

[0058] Among them, surveillance camera 3 includes:

[0059] The audible and visual alarm 301 is fixedly installed on one side of the crane beam. Its function is to allow the monitoring camera 3 to capture and monitor violations during crane hoisting, and the audible and visual alarm 301 to warn of violations.

[0060] The multi-type sensor component 5 includes:

[0061] Accelerometer 501 is fixedly installed at the bottom of the crane hoist trolley.

[0062] Displacement sensor 502 is fixedly installed at the bottom of the crane hoist trolley.

[0063] The torque sensor 503 is fixedly installed inside the crane hook. Its function is to accurately monitor the key parts of the crane by deploying the acceleration sensor 501, displacement sensor 502, and torque sensor 503, to capture the crane's operating status in real time, and to promptly detect abnormal conditions of the crane, such as overload or uneven load, thereby preventing possible safety accidents and improving the operational safety and efficiency of the lifting machinery.

[0064] The specific usage and function of this embodiment are as follows:

[0065] By adopting ZibGee wireless communication 2, the terminal computer 1, monitoring camera 3, audible and visual alarm 301, GPS high-precision positioning component 4 and multi-type sensor component 5 are connected together, ensuring stable data transmission between various nodes in the complex dock environment, guaranteeing the real-time and accuracy of the data. The application of ZibGee wireless communication 2 can also significantly reduce wiring costs and maintenance difficulty, and improve the flexibility and scalability of the device.

[0066] By deploying acceleration sensor 501, displacement sensor 502, and torque sensor 503, the key parts of the crane are precisely monitored, the crane's operating status is captured in real time, and abnormal conditions of the crane, such as overload and off-center load, are detected in a timely manner, thereby preventing possible safety accidents and improving the operational safety and efficiency of lifting machinery.

[0067] When the torque sensor 503 detects that the material under the crane hook exceeds the preset weight limit, and at the same time the monitoring camera 3 captures a worker illegally entering under the crane hook, the torque sensor 503 and the monitoring camera 3 transmit the data to the terminal computer 1 via ZibGee wireless communication 2 for calculation. Then, the terminal computer 1 controls the audible and visual alarm 301 to trigger the alarm and controls the monitoring camera 3 to capture and report the violation image to the terminal computer 1.

[0068] Through terminal computer 1 and Internet of Things (IoT) technology, crane monitoring data can be stored in the cloud, accessed remotely, and analyzed intelligently. This allows managers and maintenance personnel to remotely monitor the crane's status, perform remote fault diagnosis and maintenance guidance, and analyze historical data through terminal computer 1. The system can then predict crane failure trends and implement preventative maintenance.

[0069] The GPS high-precision positioning component 4 enables real-time acquisition of crane location information. Combined with the work plan and site conditions, it intelligently schedules the crane's work path and task allocation. This precise positioning technology not only improves work efficiency but also avoids mutual interference between cranes, achieving real-time tracking of the crane's precise location and ensuring smooth operation.

[0070] Example 2:

[0071] Based on Example 1, such as Figures 1 to 7 As shown:

[0072] Among them, surveillance camera 3 includes:

[0073] Mounting base 302 is fixedly installed on the bottom side of the crane hoist trolley by bolts, and mounting base 302 is fixedly installed on the upper part of monitoring camera 3;

[0074] The protective cover 304 is fixedly installed at the bottom of the mounting base 302. Its function is to protect the monitoring camera 3 from dust by fixing it to one side of the bottom of the crane hoist trolley through the mounting base 302.

[0075] Surveillance camera 3 also includes:

[0076] The drive motor 305 is fixedly installed inside the mounting base 302.

[0077] The drive gear 306 is rotatably connected inside the mounting base 302 and is fixedly mounted on the bottom of the drive motor 305. Its function is to drive the drive motor 305 to work continuously, and drive the drive gear 306 to rotate.

[0078] Surveillance camera 3 also includes:

[0079] A drive gear ring 307 is rotatably connected inside the mounting base 302, and the drive gear ring 307 and the drive gear 306 mesh with each other.

[0080] The cleaning scraper 303 is fixedly installed at the bottom of the drive gear ring 307. Its function is that the drive gear 306 rotates, which drives the drive gear ring 307 to rotate, and the drive gear ring 307 rotates, which drives the cleaning scraper 303 to scrape and clean the surface of the protective cover 304.

[0081] The audible and visual alarm 301 includes:

[0082] Warning light 3011, which is fixedly installed on the front side of the audible and visual alarm 301;

[0083] Speaker hole 3012 is located on the front side of the sound and light alarm 301;

[0084] L-shaped guide block 3014, two sets of L-shaped guide block 3014 are provided, and the two sets of L-shaped guide block 3014 are fixedly installed on the back of the speaker hole 3012.

[0085] The dustproof plate 3013 is rotatably connected inside the two sets of L-shaped guide blocks 3014. Its function is to allow the warning light 3011 to emit light for warning, and to allow the sound hole 3012 to pass through for warning sound. The dustproof plate 3013 protects the sound hole 3012, reducing the entry of dust and moisture into the sound hole 3012 and preventing corrosion inside the sound and light alarm 301.

[0086] The audible and visual alarm 301 also includes:

[0087] Arc-shaped guide rod 3015, two sets of arc-shaped guide rod 3015 are provided, and the two sets of arc-shaped guide rod 3015 are fixedly installed on one side of two sets of L-shaped guide blocks 3014;

[0088] Transmission iron block 3016, two sets of transmission iron block 3016 are provided, the two sets of transmission iron block 3016 are fixedly installed on the back of dustproof plate 3013, and the two sets of transmission iron block 3016 are slidably connected to the outside of two sets of arc-shaped guide rods 3015.

[0089] The elastic element 3017 is provided in two sets, and the two sets of elastic elements 3017 are fixedly installed at one end of the two sets of arc-shaped guide rods 3015.

[0090] Two sets of electromagnets 3018 are provided and fixedly installed on one side of two sets of L-shaped guide blocks 3014. Their function is that when the sound and light alarm 301 is powered on, the electromagnets 3018 generate magnetic force, which attracts the transmission iron block 3016 to move. The arc-shaped guide rod 3015 guides the movement of the transmission iron block 3016. The movement of the transmission iron block 3016 stretches the elastic element 3017 and drives the dustproof plate 3013 to rotate, so that the dustproof plate 3013 is exposed to the sound hole 3012, which facilitates the sound to pass through the sound hole 3012.

[0091] The specific usage and function of this embodiment are as follows:

[0092] Most docks are built near the sea or riverbanks, resulting in high humidity and salt content, which easily corrodes the surveillance camera 3. Furthermore, the high traffic volume and numerous machines at docks also contribute to dust and impurities adhering to the surface of the surveillance camera 3. Therefore, a protective cover 304 is used to protect the surveillance camera 3 from dust, extending its maintenance cycle and lifespan. When the protective cover 304 is used for an extended period, the drive motor 305 operates continuously, driving the drive gear 306 to rotate. The drive gear 306 then drives the drive gear ring 307, which in turn drives the cleaning scraper 303 to clean the surface of the protective cover 304, ensuring its permeability and preventing excessive dust and impurities from adhering to the cover, thus affecting the use of the surveillance camera 3.

[0093] When the audible and visual alarm 301 is powered on and emits sound and light to sound an alarm, the electromagnet 3018 is powered on and generates magnetic force. The electromagnet 3018 attracts the transmission iron block 3016 to move through the magnetic force. The arc-shaped guide rod 3015 plays a guiding role when the transmission iron block 3016 moves. The movement of the transmission iron block 3016 stretches the elastic element 3017 and drives the dustproof plate 3013 to rotate, so that the dustproof plate 3013 exposes the sound hole 3012, so that the sound can pass through the sound hole 3012.

[0094] When the audible and visual alarm 301 is in standby mode, the electromagnet 3018 stops receiving power and loses its magnetic force. The elastic element 3017, under the action of elasticity, drives the transmission iron block 3016 to reset. The reset of the transmission iron block 3016 drives the dustproof plate 3013 to block the sound hole 3012, preventing moisture, dust and other impurities from entering the sound hole 3012 and contaminating and corroding the inside of the audible and visual alarm 301.
