Hard super-large plate lifting appliance

Abstract

The invention relates to a hard-state super-large disc lifting appliance which comprises a lifting bearing piece, a lining plate and a plurality of supporting units, each supporting unit comprises a rotary disc, a long tongue plate and a driving assembly, the lifting bearing piece is fixedly connected with the lining plate, a cavity is formed in the lining plate, the rotary disc is rotatably installed on the lining plate, and the long tongue plate is fixedly connected with the rotary disc. The long tongue plate is installed on the lining plate in a sliding mode, the driving assembly is connected to the rotating disc, and when the driving assembly drives the rotating disc to rotate, the rotating disc can drive the long tongue plate to stretch out of a cavity of the lining plate or retract into the lining plate. The upper surface of the long tongue plate is in direct contact with the bottom surface of the coil pipe, the upper surface of the long tongue plate and the bottom surface of the coil pipe have enough contact area, and the special plate surface material of the long tongue plate can avoid deformation of the pipe at the contact position, so that the operation process is simplified, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a sling, in particular to a sling used for a copper pipe hard super large plate. Background technique [0002] In precision seamless copper pipe production enterprises, the finished coils after winding by the rewinding machine are generally unloaded and transported by internal expansion or outsourcing spreaders. Generally, the rewinding coil spreaders include suspenders and swing arm rods. , positioning plate, support plate and connecting rod and other components. However, the production method of the hard super large coil is different from that of the rewinding machine, and the traditional rewinding coil spreader cannot be applied to the hard super large coil. At present, lifting or shoveling is used for handling super large coils after winding. Before winding, special heat-resistant plates, split pallets, liners and even transport transfer frames are placed on the bottom of the coils, which is not conducive to the high-speed...

However, the production method of the hard super large coil is different from that of the rewinding machine, and the traditional rewinding coil spreader cannot be applied to the hard super large coil

At present, lifting or shoveling is used for handling super large coils after winding. Before winding, special heat-resistant plates, split pallets, liners and even transport transfer frames are placed on the bottom of the coils, which is not conducive to the high-speed rotation of winding. stability and increase the labor intensity of the operator, which is very inconvenient and expensive, so a new way is needed to solve the above problems
