The chain sling consists of a sling chain, accessories such as hanging rings, hanging hooks, hanging belts and the like, and is a metal sling, and the chain sling is divided into a 60-level sling, an 80-level sling, a 100-level sling, a 120-level sling and the like according to bearing capacity. The higher the level, the higher the chain carrying capacity of the same specification. The chain sling has the advantages of high bearing capacity and good safety, the breaking elongation rate is more than or equal to 20%, the combination form is various, the universality and the interchangeability are strong, the length is adjustable, the storage is easy, the service life is long, the use temperature range is large, the detection is easy, and the convenience and the rapidness are realized.
When the heavy objects are required to be carried, one end of an opening of the lifting hook penetrates through a hole or a groove preset in the object, the object is carried to another position by using the lifting mechanism, and finally the lifting hook is taken down. However, when the object is carried, the hook is put down, and the hook is clamped in the hole due to gravity, so that an external force is required to be provided to take down the hook, and nowadays, most of the hook is manually taken down, so that a problem is derived, if the object is carried to a low place, the hook can be easily canceled, but if the object is carried to a high place, the hook is required to be manually carried to a corresponding high place to take down the hook, so that the labor and time are consumed, the working efficiency is low, and in addition, the possibility of injury to personnel is also low in the process, and the safety is low.
The utility model comprises the following steps:
the utility model aims to solve the defects in the prior art and provides a lifting appliance easy to detach.
An easy-to-detach lifting appliance comprises a main body, wherein the main body comprises a lifting hook, a rope, a connecting ring and a weight;
one end of the weight is provided with a flange, and the edge of the flange is provided with a through hole;
the lifting hook is connected with the crane through a connecting mechanism; the lifting hook comprises a connecting part, a hook part and a connecting part, wherein the connecting part is of a straight structure, the hook part is of an open arc bending structure, and one end of the connecting part is connected with one end of the hook part;
the connecting ring is of a closed annular structure, the connecting ring is arranged at the bottom of the hook part, the rope is made of flexible materials, and one end of the rope is fixed on the annular ring.
Working principle: according to the utility model, a long rope is connected to the connecting ring at the bottom of the lifting hook, one end of the hook part of the lifting hook is inserted into the through hole on the flange plate of the weight, so that the lifting hook hooks the weight, the weight is conveyed to a high position by the crane, after the conveying is finished, the lifting hook is taken out from the through hole by pulling the rope at the bottom of the hook part, and meanwhile, the angle for pulling the rope can be adjusted according to different positions.
In order to facilitate the connection between the crane and the lifting hook, the connecting mechanism comprises a chain, one end of the chain is connected with the crane, and the other end of the chain is connected with the other end of the lifting hook connecting part through a fixing structure.
In order to ensure the connection between the chain and the lifting hook, the fixing structure comprises a bolt, a nut and a fixing ring;
the fixed ring is a U-shaped bending metal piece, the other end of the hook connecting part is positioned between two ends of the fixed ring, threads are arranged at the bottom of the bolt, and the bolt sequentially penetrates one end of the fixed ring, the connecting part of the hook, the other end of the fixed ring and the nut.
In order to ensure the strength of the lifting hook, the lifting hook is of an integrated structure, and the lifting hook is made of metal.
The beneficial effects are that: compared with the prior art, the utility model has the advantages that one rope with enough length is connected to the connecting ring at the bottom of the lifting hook, one end of the hook part of the lifting hook is inserted into the through hole on the flange plate of the weight, the lifting hook hooks the weight, the weight is transported to a high position by the crane, after the transportation is finished, the lifting hook is taken out from the through hole by pulling the rope at the bottom of the hook part, and meanwhile, the angle for pulling the rope can be adjusted according to different positions.
In the prior art, the corresponding problem is not considered, and the function of taking down the lifting hook still needs to be that the lifting hook can be taken down by direct contact with the object.
The lifting hook is simple in structure, has no complicated and redundant structure, can be conveniently applied to most lifting slings, wherein the rope is equivalent to one extension of a human hand, is still manually operated, obviously utilizes the advantages of stronger manual flexibility and random strain capacity according to different actual conditions, can adjust different angles to take off the lifting hook according to different actual positions, and is automatic and can not cope with various different conditions and angles like manual work.
Compared with other flexible materials, the rope is lighter in weight, does not add greater burden to the hoisting machine and the hanging chain, and is more convenient to adjust the angle due to the soft characteristic.
