Description
Technical Field
The utility model relates to a pier freight technical field especially relates to an anticreep lifting hook suitable for plywood operation.
Background
The port wharf is a comprehensive wharf mainly for loading and unloading sundries, and is mainly used for loading and unloading goods such as plywood, paper pulp, engineering machinery, steel and the like. The operation of the piece goods is characterized by complex process, various types of tools and a large number of tools. The hook for hooking the rigging is an indispensable configuration for grocery operation, and especially on a special lifting appliance such as plywood and paper pulp, the safety problem is always a key point of attention.
In recent years, as the main goods category of a working area, the loading and unloading amount of plywood is increasing, and the requirements on safety and efficiency are also increasing. After years of research and improvement, the tool for loading and unloading the plywood mainly takes a frame type special lifting appliance as a main part. The hanger is mainly formed by combining a frame, a chain and a lifting hook through a connecting piece. The lifting hook on the frame lifting appliance is used for hooking riggings such as a braided belt special for plywood, and the lifting of goods is realized. Through experience accumulation for many years, the plywood hoisting process is mature day by day, but the defects are exposed gradually, the plywood hoisting process is mainly focused on the anti-falling of the hanging strip, and the lifting appliance is promoted to be continuously improved so as to improve the intrinsic safety of the tool and improve the operation efficiency.
Through the analysis of the safety accidents caused by plywood lifting in recent years, the accidents caused at present are mainly concentrated on the lifting hook arranged on the lifting appliance. At present, the lifting hooks arranged on the plywood lifting appliance are mainly of three types, wherein one type is that the hook end is in a rectangular section, the other type is that the hook end is in a conical section, and three hook heads are provided with anti-falling devices.
The following hidden troubles exist in the use process:
1. when the hook end is used for a hook with a rectangular cross section, the lute button of the woven belt is wide, the lute button is easy to put on the hook end when the hook is hooked, the lute button does not fall into the hook cavity, and if a worker does not confirm the lute button, the woven belt falls off after goods are lifted, so that the goods fall.
2. When the lifting hook with the conical section is used, the hook end is easy to hook into the space between the strands, so that the strands are scattered, or the pipa clasp of the braided belt is penetrated, the braided belt is torn, and the goods fall.
3. The existing lifting hook is not enough in anti-falling design, and some anti-falling devices are easy to deform due to collision, so that the rotation is not flexible, the operation is inconvenient, and the operation efficiency is influenced. Some woven belts are easy to be broken when hung at the hook end in the operation.
In summary, aiming at the defects of the prior art, an anti-drop lifting hook suitable for plywood operation is particularly needed to solve the defects of the prior art.
