Description

Technical Field

[0001] This utility model belongs to the field of electrolytic crane technology, specifically relating to an anti-collision lifting rod device for electrolytic cranes. Background Technology

[0002] Overhead cranes, commonly known as bridge cranes, are overhead structures that span workshops, warehouses, or material yards. They reduce manual labor intensity and improve production efficiency by hoisting and moving heavy objects. Their main structure is a bridge frame, supported at both ends by running devices on elevated tracks, enabling them to be moved and lifted. Electrolytic overhead cranes are core special lifting equipment in aluminum electrolysis production lines, specifically designed for harsh industrial environments such as high temperatures, strong magnetic fields, and high dust levels. They handle critical process operations such as electrolytic cell maintenance, anode replacement, and material transportation.

[0003] Typically, multiple overhead cranes need to operate on a single track. Among them, a crane anti-collision device with publication number CN201553553U protects the overhead cranes through a rangefinder and an alarm device. Although it can prevent collisions between overhead cranes, it reduces the carrying efficiency of the overhead cranes to some extent. Utility Model Content

[0016] The following are specific implementation cases and appendices. Figures 1-4The present invention will be further described, but it is not limited to these embodiments. The present invention provides a technical solution: an anti-collision lifting rod device for an electrolytic crane, comprising: a crane body 1, a lifting rod structure installed on the front wall of the crane body 1, and two sets of locking structures installed on the rear wall of the crane body 1; the lifting rod structure includes: two lifting rotating seats 2, two lifting frames 3, a lifting baffle 4, and a lifting drive motor 5; the two lifting rotating seats 2 are respectively installed on the front wall of the crane body 1, the two lifting frames 3 are respectively movably installed inside the lifting rotating seats 2 via shafts, the lifting baffle 4 is installed on the front wall of the two lifting frames 3, the lifting drive motor 5 is installed on the front wall of the crane body 1, and the drive end of the lifting drive motor 5 is connected to the lifting frame 3, a laser rangefinder 11 is installed on the front wall of the lifting baffle 4, two light sensors 12 are installed on the front wall of the lifting baffle 4, and limit supports 13 are installed on the lower wall of the two lifting frames 3.

[0017] As a preferred embodiment, the two sets of locking structures further include: a locking movable bracket 6, a locking support shaft 7, a locking motor 8, and a locking bolt 9; the locking movable bracket 6 is installed on the rear wall of the crane body 1, the locking support shaft 7 is movably installed inside the locking movable bracket 6 via bearings, the locking motor 8 is installed inside the locking movable bracket 6, and the drive end of the locking motor 8 is connected to the locking support shaft 7, and the locking bolt 9 is installed at the top of the locking support shaft 7.

[0018] As a preferred option, two locking tubes 10 are installed on the rear wall of the crane body 1, and each of the two locking tubes 10 has a bolt fixing groove.

[0019] Working principle:

[0020] I. Installation before use: Inside the electrolysis plant, the overhead crane body 1 is placed directly on the pre-set track. The operator connects the external AC power supply to this invention to provide energy for the electrical appliances within it; and the matching controller is connected to this invention to provide control and operating logic for the electrical appliances. This invention has three working modes: standalone working mode, collaborative working mode, and cooperative working mode.

[0021] II. Standalone working mode: On the preset track, there is only one crane body 1. At this time, the crane body 1 can run at full speed, improving the transportation efficiency of the crane body 1.

[0022] III. Collaborative Working Mode: On the preset track, there are only multiple crane bodies 1, and all multiple crane bodies 1 are working. At this time, the lifting drive motor 5 needs to work. The drive end of the lifting drive motor 5 drives the lifting frame 3 to rotate inside the lifting rotating seat 2, allowing the lifting baffle 4 to move from inside the crane body 1 and stop on the front wall of the crane body 1. At this time, the limiting support 13 is supported between the crane body 1 and the lifting frame 3, and the limiting support 13 can provide support for the lifting baffle 4. The lifting drive motor 5 is a brake motor, which can stop and stop rotation at a specified angle. The laser rangefinder 11 begins operation, detecting the distance between two adjacent crane bodies 1 at a frequency of once every two seconds. When the distance between two adjacent crane bodies 1 is greater than the high-speed threshold, the crane body 1 can operate at full speed; when the distance is less than the high-speed threshold but greater than the safety threshold, the crane body 1 operates at slow speed; when the distance is less than the safety threshold, the crane body 1 operates at extremely low speed. When the light sensor 12 detects a sudden lack of light, indicating that two adjacent crane bodies 1 are about to collide, both crane bodies 1 simultaneously brake and power is cut off to prevent a collision. The laser rangefinder 11 uses the ZYT-0100 model, which does not require a reflector.

[0023] IV. Cooperative Working Mode: The operator activates the cooperative mode through the controller. At this time, the two adjacent overhead crane bodies 1 move closer and closer until the locking tube 10 and the locking movable bracket 6 come into contact, and the locking bolt 9 is inserted into the bolt fixing groove of the locking tube 10. The locking motor 8 starts to rotate, and the locking support shaft 7 drives the locking bolt 9 to rotate, so that the locking bolt 9 is inserted deep into the bolt fixing groove of the locking tube 10. The locking motor 8 is a brake motor, which can keep the locking bolt 9 locked.
