Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a special sling for loading and unloading lower cabin operation equipment at a port. Background Art

[0002] A sling refers to a device used in lifting machinery to lift heavy objects. When loading and unloading cargo at the port, professional slings are usually required to lift the cargo containers.

[0003] According to the description of an anti-falling port spreader disclosed in the patent website (authorization announcement number: CN 219567268U), "The utility model discloses an anti-falling port spreader, which relates to the field of lifting equipment, including a spreader frame and two center frames arranged on the lower surface of the spreader frame, the center frame includes a frame body, a motor seat is fixedly connected to the outer surface of one side of the frame body, a motor is arranged inside the motor seat, a screw rod is fixedly connected to the output end of the motor, and the screw rod is a two-stage design with different rotating threads, and the outer cylindrical surface of the screw rod is slidably connected to two ball nut seats. Compared with the existing ordinary port spreaders, the anti-falling port spreader, before the spreader lifts the container, the motor drives the ball nut seat on the screw rod to slide, and the four clamps continuously approach the container, driving the entire spreader to reach a position directly above the container, and the operator does not need to constantly adjust the position of the spreader to reach a suitable locking position, which ensures the stable locking operation and prevents the container from accidentally falling off due to incorrect locking position."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the motor drives the screw rod to rotate, causing the clamp to slide inward, driving the sling to quickly position above the container. The set alarm device can warn in case of overweight, but in actual use, the locking unit of the device cannot be adjusted in position, which results in that when the corresponding slot position of the container does not correspond, the locking unit that cannot be adjusted cannot be connected to the container for lifting. Therefore, it is necessary to improve a special sling for port loading and unloading lower cabin operation equipment to solve the above problem. Utility Model Content
