Abstract

Provided is a lifting appliance for lifting and carrying a container. The invention relates to the empty container lifting appliance having high-performance tapered end mechanisms. The lifting appliance includes a carriage, a fixing arm, a left telescopic arm, a left floating arm, a right telescopic arm, a right floating arm and telescopic oil cylinders; each floating arm includes an oil cylinder, a tapered end, an address recognizing piece, a box-landing signal switch and the like, wherein one side of the tapered end is provided with a security protection mechanism, the security protection mechanism includes a guide seat, and the guide seat is internally provided with an upright movable lifting pin, one side of the top of the lifting pin is provided with a protruding-outward positioning block, the top of the lifting pin is provided with a blind hole, the blind hole is internally insertedly provided with a guide rod, and the guide rod is sleevedly provided with a spring. With adopting of the lock catch type fixing tapered ends and the security protection devices, on one hand, the shear-bearing capacity of lock catches is utilized to replace the screw thread pair bending resistant capacity, on the other hand, precision positioning of vice springs is utilized and the guide structure is optimized, so that the strength of the tapered end mechanisms is increased, and the security of the tapered end mechanisms is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of heavy-duty forklifts, and in particular relates to an attachment of heavy-duty forklifts, that is, a spreader for container lifting. Background technique [0002] At present, when the container spreader on the heavy-duty forklift lifts the container, the lock head of the floating arm of the spreader rotates 90° and cooperates with the container lock hole to lock the container, and then lift the container. Due to the unreasonable design of the lock mechanism itself and the lack of reliable safety protection, there are often phenomena such as lock looseness and malfunction. When loaded, it is easy to cause fatigue of the thread pair, causing damage and loosening of the lock head; 2. The unreasonable design of the safety protection mechanism causes the lock head mechanism to be easily stuck; 3. The address recognition piece is rigidly fixed, which is easy to damage the proximity switch; 4. If the switch is ...
