Description

Technical Field

[0001] This utility model relates to the technical field of container loading and unloading equipment, specifically to an automatic locking lifting device for container corner fittings. Background Technology

[0002] With the rapid development of the logistics industry, the demand for efficient, safe, and highly automated container handling equipment is increasing during the container loading and unloading process.

[0003] Traditional spreader rigs typically require operators to manually operate the locking device, engaging it with the container corner fittings to lock or unlock. This process demands a certain level of skill and experience from the operator, involves numerous steps, and increases the complexity of loading and unloading operations. Manual operation is relatively unreliable and susceptible to factors such as operator fatigue and inattention. Improper operation can lead to the locking device failing to lock or unlock correctly, resulting in safety accidents or equipment damage. Furthermore, the spreader's lifting position cannot be accurately determined, reducing its lifting precision. Therefore, an automatic locking spreader for container corner fittings is needed to address these issues. Utility Model Content

The multi-strand steel rope 106 can improve the stability of hoisting.

[0030] The working process of this utility model is as follows: When the container corner fitting automatic locking spreader designed in this solution is in operation, according to the specifications of the container, the motors 203 on both sides of the spreader mechanism drive the threaded blocks 205 to move on the lead screw 204, and cooperate with the slide rails 207 and sliders 208 to move the position of the sling 301, thereby positioning and adjusting the lifting mechanism on both sides so that the spreader is suitable for the specified container. When the position sensor 305 detects that the corner fitting is close, the telescopic automatic locking rod 307 can penetrate the corner fitting and extend into the through hole 308 to achieve automatic locking. The same automatic control method is used. When unlocking is required, the extended end of the telescopic automatic locking rod 307 is withdrawn from the through hole 308 to complete the unlocking.
