Multi-group steel coil seat frame lifting appliance

Abstract

The multi-group steel coil seat frame lifting appliance comprises a lifting lug, a vertical guide mechanism, a connecting frame, a translation mechanism and a limiting type lifting arm, an opening and closing device is installed at the bottom of the lifting lug in a matched mode, the connecting frame is arranged at the bottom of the lifting lug and connected with the lifting lug through the vertical guide mechanism, and the vertical guide mechanism is used for achieving relative sliding of the lifting lug and the connecting frame in the vertical direction. The two limiting type suspension arms are symmetrically arranged along the vertical center line, and the limiting type suspension arms are connected with the connecting frame through translation mechanisms; the vertical guide mechanism is connected between the lifting lug and the connecting frame through a rhombic connecting rod movement mechanism formed by an upper-layer pulling plate and a lower-layer pulling plate; the translation mechanism is connected with the limiting type suspension arm through the symmetrically-arranged connecting main plate and the auxiliary plate and can control the limiting type suspension arm to translate under the condition that the height is variable. The lifting device has the advantages of reliability in use, low failure rate, convenience in maintenance and the like, can meet the lifting requirements of steel coil seat frames of various specifications, improves the loading and unloading efficiency of the steel coil seat frames and reduces the loading and unloading time.

Description

technical field [0001] The invention relates to the technical field of load hanging equipment, in particular to a multi-group steel coil seat frame hanger. Background technique [0002] In the traditional railway transportation of rolled steel coils, the steel coils are required to be placed vertically in the wagon and reinforced, while the steel coils in the steel coil rolling process of steel mills are often in a horizontal state, so that steel coils are required before railway transportation. The coil is turned 90°. During the loading and unloading process, it is necessary to use the approved vertical coil clamps for hoisting to realize the vertical transportation of steel coils. According to the latest regulations of railway transportation, under the condition of using a special steel coil stand to fix it, it can be transported in a horizontal steel coil state, which reduces the hoisting process of turning the steel coil 90 and fixing it in the wagon. [0003] When the ...

Problems solved by technology

When the on-site steel coil holders are used for centralized palletizing and truck loading and unloading, when steel wire ropes are used for hoisting, due to the many specifications and various combinations of steel coil holders, when the general lifting equipment is transferred, multiple loading and unloading personnel are required to participate in the work, which is time-consuming and labor-intensive. It is laborious and has great potential safety hazards. Cranes using electric spreaders are often limited by the power supply of the site.
