Description

Technical Field

[0001] This utility model belongs to the technical field of emergency power connection devices, specifically relating to a special emergency power connection device for port yard cranes. Background Technology

[0002] Currently, most heavy industrial ports utilize yard cranes. These cranes rely on their own motors for power during transit and relocation. During peak operating periods, yard cranes frequently need to move between yards; if their motors fail to supply power during transit or relocation, the cranes will lose power and become immobile, stopping in the work area and disrupting operations. Once a yard crane has moved out of the storage yard, it is generally far from the mains power supply (also called industrial frequency AC power) to the contact wire. If the crane loses power and stops working at this point, there are currently no effective measures to quickly restore its power supply and resume normal operation. Previously, there were two main emergency response measures. The first was to wait for the gantry crane to tow the malfunctioning crane into the yard, then connect it to the mains power supply via the contact line. Once powered, the crane would resume normal operation. However, this method was cumbersome, inefficient, and severely impacted on-site operations. The second method involved connecting two yard cranes with power cables to bring them into the yard. However, this required two operators to control speed and distance, and carried the risk of cable breakage or collision, making it labor-intensive and risky. Therefore, it is evident that emergency rescue was difficult when yard cranes lost power after leaving the yard. Currently, there is a lack of an emergency power-connecting device to facilitate the re-establishment of power connection between a power-loss yard crane and the contact line mains power supply to restore power.

[0003] Therefore, a new technology is needed to address the lack of an emergency power-connecting device in existing technologies for quickly restoring normal power operation to a power-destroyed field bridge. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a special emergency power-connection device for port yard cranes, which can quickly restore the normal power operation of a power-destroyed yard crane, thus facilitating emergency rescue.

[0005] The present invention adopts the following technical solution:

[0006] A special device for emergency power connection of port yard cranes includes a power receiving device and a cable assembly. The power receiving device can be electrically connected to the mains power of the sliding contact line. The cable assembly includes a plug assembly and a socket assembly. One end of the plug assembly is connected to the cable of the power receiving device. One end of the socket assembly can be electrically connected to the yard crane to be powered. The other end of the plug assembly can be electrically connected to the other end of the socket assembly.

[0007] Furthermore, one end of the socket assembly is connected to the air switch of the field bridge to be powered via a three-phase four-wire connection.

[0008] Furthermore, the other end of the plug assembly is a three-phase four-wire plug, and the other end of the socket assembly is a three-phase four-wire socket, and the three-phase four-wire plug can be inserted into the three-phase four-wire socket.

[0009] Furthermore, the power supply device includes a frame assembly and a carbon brush device. The carbon brush device is provided on the frame assembly. The frame assembly is used to fix the sliding contact line slot, and the carbon brush device is used to connect to the mains power of the sliding contact line.

[0010] Furthermore, the carbon brush device includes a carbon brush box and carbon brush plates. The carbon brush box is disposed on the frame assembly, and the carbon brush plates are disposed on the carbon brush box. The carbon brush plates are connected to one end of the plug assembly via a cable, and the carbon brush plates can be electrically connected to the mains power of the sliding contact line.

[0011] Furthermore, the carbon brushes are provided with at least four; one end of the plug assembly is connected to the carbon brushes via a three-phase four-wire connection.

[0012] Furthermore, the frame assembly includes a main frame, several sets of horizontal wheels, and several traveling wheels; the carbon brush device is provided on the main frame; the several sets of horizontal wheels are provided on the main frame for fixing the main frame to the sliding contact line slot; the several traveling wheels are provided on the main frame for the main frame to slide on the sliding contact line slot.

[0013] Furthermore, it also includes a cable reel, on which the socket assembly is disposed, the cable reel being used to extend and retract the socket assembly.

[0014] Furthermore, the cable reel includes a turntable and a base frame, the turntable being disposed on the base frame, and the turntable being used to retract and extend the socket assembly.

[0015] Furthermore, it also includes an auxiliary trolley for loading and unloading the power supply device and the cable reel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a power-taking device that can be fixed to the sliding contact line slot, enabling electrical connection with the mains power supply. A plug and socket assembly connects the power-taking device to the yard crane awaiting power, facilitating rapid restoration of operation after a power outage and preventing prolonged obstruction of the working passageway due to power failure, thus avoiding disruption to normal production activities. This invention also enables long-distance circuit connection between the yard crane and the mains power supply, overcoming the previous drawbacks of yard cranes being unable to operate once power is lost outside the yard, and the inconvenience of rapid emergency rescue in such situations. Furthermore, this invention provides emergency power to port yard cranes, improving their operational stability and reliability, reducing economic losses caused by power outages, and facilitating maintenance and repair by personnel, thus enhancing the maintainability and operability of the equipment.
