Abstract

The invention discloses a press-down twist lock autorotation hanger for hoisting a container. The hanger is directly arranged on a hoisting beam of hoisting equipment, and does not need hydraulic, pneumatic or electric drive; and by using downward pressing of the hoisting equipment, a twist lock head rotates for 90 degrees, hooking or loosening of a vertex angle member of the container is finished, and the hoisting operation is realized. The press-down twist lock autorotation hanger is characterized by comprising a hanger framework, an upper mounting seat, a lower mounting seat, a return spring enclosure, a twist lock assembly, a jacking device and a signal switch. The hanger framework has a frame-shaped structure and is used for installing each member. The twist lock assembly comprises the twist lock head, a twist lock rod, a rotary pin, a rotary block, a rotary block return spring, a spring stop block, a thrust bearing, a return spring, a stop block pin, a clamping spring, a clamping steel ball and a twist lock pin. The upper mounting seat is provided with a spiral groove, the middle of the lower mounting seat is provided with a circular hole, and a square groove is processed on the upper end face of the lower mounting seat. The signal switch is used for giving twist lock state signals. The press-down twist lock autorotation hanger has simple and compact structure, reduces the manufacture and maintenance costs, and has good practical effect.

Description

technical field [0001] The invention relates to a push-down twist-lock self-rotating spreader for container hoisting, which is suitable for container forklifts, container gantry cranes and other container hoisting equipment to hoist containers. Background technique [0002] At present, most containers are loaded into transport trailers and stacked at yards and docks, all of which are completed by lifting equipment such as container forklifts or gantry cranes. The hooks of these lifting devices are mostly T-shaped twist lock parts, which are inserted along the long holes of the top corner pieces on the upper part of the container. The twist lock head rotates 90 degrees to hang the top corner of the container to complete the hanging. After the container is loaded into the transport trailer or stacked, the T-shaped twist lock head is driven 90 degrees, and the hoisting equipment is separated from the container. [0003] This method is reliable and mature in technology, and is...
