Description

Technical Field

[0001] This invention relates to the disassembly and assembly of container crane wheels, and more specifically to an electric tire press and electric tire pressing method for container crane wheels. Background Technology

[0002] Container terminals typically utilize equipment such as quay cranes, real-time transport cranes (RTGs), reach stackers, forklifts (empty forklifts), heavy-duty forklifts, and trailers. Among these, the replacement of wheels for RTGs, reach stackers, forklifts (empty forklifts), heavy-duty forklifts, and trailers is a frequent, labor-intensive, and dangerous task. Wheel replacement is usually performed manually using self-made terminal tools. Container cranes use large wheels (RTGs use 21.00-35 wheels with diameters exceeding 2 meters) and have high tire pressure. Furthermore, heavy-duty engineering wheels often experience rust on the hubs and accessories, and aging of seals after prolonged use, making disassembly extremely difficult, inefficient, and posing significant risks to on-site engineers.

[0076] The present invention has the following advantages:

[0077] 1. High efficiency, saving time and effort.

[0078] Through on-site use of electric tire presses and comparison with the previous docking and disassembly of 21.00-35 tires, the average time for a single yard crane to disassemble a 21.00-35 tire has been reduced from 36 minutes to about 18 minutes, with an average efficiency improvement of over 50% (excluding inflation time).

[0079] 2. Ensure safe operation and eliminate potential safety hazards.

[0080] In traditional docks, accidents involving personal injury occasionally occur when inflating new tires due to improper installation location. With this invention, when disassembling and inflating wheels and new tires, the wheels are placed in a sealed box and operated remotely with a remote control, eliminating safety hazards by keeping personnel away from the work site.

[0081] 3. Green and energy-saving.

[0082] Compared to the traditional hydraulic system used to drive hydraulic cylinders at docks, the use of electric actuators can reduce the use of hydraulic oil and reduce environmental pollution caused by oil leaks.
