Description

Technical Field

[0001] This utility model relates to the field of electronic protection technology, specifically to a ground electronic protection device for railway mobile loading and unloading machinery operations. Background Technology

[0002] In railway freight yard operations, the operational safety of mobile loading and unloading machinery such as container front-end cranes and grab (crush) machines is of paramount importance. With the continuous development of the railway transportation industry, the efficiency and safety of freight yard operations have become the focus of attention. Traditional protection methods mostly adopt fixed physical fences or manual monitoring, but these methods have many shortcomings in practical applications and are difficult to meet the needs of modern railway freight yards for efficient, flexible and safe operations. Currently, the commonly used protective measures in railway freight yards mainly include the following: Fixed physical fences: These fences restrict the work area and prevent unauthorized personnel and vehicles from entering. However, these fences lack flexibility and cannot adapt to the dynamic adjustment needs of the freight yard's work area. Furthermore, when frequent changes to the work area are required, the adjustment costs are high and time-consuming. Manual monitoring: Dedicated personnel are assigned to monitor the work area to promptly detect and handle abnormal situations. However, manual monitoring suffers from blind spots and fatigue, making it difficult to achieve comprehensive, real-time, and effective safety protection, especially in large or complex work areas where the monitoring effect is even worse. Simple laser beam detectors: Some freight yards have begun to try using laser beam detectors for protection. However, these devices typically have limited functionality, only performing basic intrusion detection. They cannot distinguish between authorized work vehicles and illegal intrusion targets, leading to misjudgments and disrupting normal operational processes. Existing protective measures have the following drawbacks: They are simplistic and lack flexibility, failing to adapt to dynamic changes in yard operations and thus unable to adjust protection zones and strategies in a timely manner, making them ill-suited to changing work environments; traditional laser beam detectors and other protective equipment can only detect objects blocking the laser beam but cannot distinguish between authorized vehicles and unauthorized intruders, leading to false alarms and disruption of normal operations; existing protective equipment lacks portability and adaptability in its design, making rapid deployment and adjustment difficult and unable to meet the needs of frequent changes in yard work areas; and existing protective equipment lacks effective integration and coordination with other management systems in the yard (such as monitoring and communication systems), hindering information sharing and coordinated control, thus reducing overall protective effectiveness. To address the aforementioned problems, the inventor proposes a ground-based electronic protection device for railway mobile loading and unloading machinery operations. Utility Model Content

[0025] A pull rod 42 is slidably mounted on one side of the portable case 41, and several No. 2 universal wheels 43 are mounted on the bottom of the portable case 41. An equipment box 45 is fixedly mounted on the upper surface of the portable case 41. A cover plate that can be removed by screws is provided on the upper surface of the equipment box 45. Several slots are provided on the bottom wall of the equipment box 45. By setting up the equipment box 45 and removing the cover plate on the upper surface, the various components of the electronic protection module 2 can be installed in the multiple slots on the bottom wall of the equipment box 45 (excluding the laser emitter receiver 21).

[0026] The inner wall of the portable case 41 is fixedly provided with several guide rods 62, and the movable plate 61 is slidably disposed on the guide rods 62. By providing the guide rods 62, the guide rods 62 can guide the movable plate 61 in the horizontal direction, so that the movable plate 61 can move in the horizontal direction.

[0027] A second motor 68 is fixedly installed on the inner wall of the portable case 41. A second rotating rod 69 is fixedly installed at the drive output end of the second motor 68.

The second rotating rod 69 can make the double-ended screw 67 rotate through the two second bevel gears 7.

[0028] Working principle: When in use, the portable case 41 is first transported to the target cargo site. During the transportation process, the outer shell of the portable case 41 protects the internal fence bracket assembly 1 and electronic protection module 2 from damage. Upon arrival at the target cargo yard, the staff opened the door 44 of the portable case 41, took out the fence bracket assembly 1 and the electronic protection module 2, and selected suitable positions at the entrances and exits at both ends of the cargo yard according to the layout of the work area. They then unfolded the fence bracket assembly 1 and fixed the two rods of the installation rod 13 at the hinge 131 with bolts and connectors to form a whole. Then, they installed the electronic protection module 2 and determined its installation height and installation angle. The staff transported the fence support assembly 1 and the electronic protection module 2 to the entrances and exits at both ends of the freight yard operation area. According to the operation requirements, the height of the fence support assembly 1 was adjusted by adjusting the component 3 to achieve a suitable protection height. The device was moved to the designated position by the first universal wheel 15 and the first universal wheel 15 was locked to ensure stability. The laser emitter of the laser transmitter and receiver 21 emits a laser beam, forming a horizontal laser beam protection boundary with the laser receiver. The RFID reader 22 reads the tag information of the authorized vehicles inside in real time. The main control chip 25 processes and judges the acquired data. When an object blocks the laser beam, the main control chip 25 receives a signal and, combined with the verification result of the RFID reader 22, determines whether it is an illegal intrusion. If it is determined to be an illegal intrusion, the warning light buzzer 24 is triggered to alarm, and the alarm signal is transmitted to the remote controller 27 through the LoRa wireless communication module 23. If the position of the protective boundary needs to be adjusted during the operation, the staff can push it to the new position using the No. 1 universal wheel 15, relock the No. 1 universal wheel 15, and continue working after ensuring stability. After the work was completed, the staff turned off the power, removed the electronic protection module 2 from the bracket, folded up the foldable mounting rod 13, and put all the components back into the portable case 41 for the next use. like Figure 7 As shown, a pair of electronic protection modules 2 can also be installed at the entrances and exits at both ends of the freight yard, forming a protective boundary covering the work area together with the rails on both sides. At the entrance of the dangerous area, such as near the edge of the platform or at the junction with other work areas, electronic protection modules 2 are deployed to prevent unauthorized personnel and vehicles from entering. The spacing between each pair of electronic protection modules 2 is controlled at 5-10 meters to balance the protection coverage and equipment cost.
