Abstract
The utility model relates to a carry compact chain that hangs big load heavy object comprises a plurality of chain links and round pin axle. The chain link falls into two parts, and one of them part is the inner link, and another part is the outer link, and the inner link is the axle, and the outer link is hole, inner link and outer link clearance fit in every two adjacent chain links to through round pin axle constitution activity hinge, be fixed connection between round pin axle and the inner link of activity in the hinge, and be between the outer link spool and the clearance fit in hole, be equipped with the bush in the round pin shaft hole on the outer link. The entity thickness on the round pin axle length direction is followed along the entity thickness more than or equal to outer link on the round pin axle length direction to the inner link. The utility model discloses insert the inner link in a plurality of the chain links and close in the outer link to constitute a plurality of activity hinge through the round pin axle, can form a confined and carry the chain sling strip. Carrying with such chain cuff and hanging big load heavy object, the safety and stability is reliable. The utility model has the advantages of reasonable in design, simple structure, manufacturing be convenient, small, it is big to bear.
Description
Technical field
This utility model is related to a kind of lifting chain, more particularly to a kind of compact type chain for being capable of lifting big load weight
Structure, belongs to lifting member design and manufacturing technology field.
Background technology
Lifting chain requisite equipment when being large-sized object lifting.Traditional lifting chain be mostly ring fastening type or
Carrier bar wafer type, i.e.,：Chain is mutually buckled by some pitch chain rings or carrier bar is formed to folder.The advantage of this chain is：Structure
It is relatively simple, can use cooperatively with various hoisting machineries, the chain of carrier bar wafer type can also be used as power transmission.It has the disadvantage：
1st, the closed joint in chain link is that welding is formed, therefore its load capacity is limited, and plumb joint easily tears very if overstepping the extreme limit
To disengagement；2nd, processing technique is special, and ring ring quality has high demands, and particularly big load chain cost of manufacture is expensive；3rd, bundle hoop weight
When, often it is a contact form between chain and weight, thus less stable, easily cause landing；4th, carrier bar wafer type chain
Bar, due to reducing intensity behind its tooling pin, set and hole.In sum, ring fastening type hoisting chain and carrier bar wafer type chain be not
The needs of lifting big load weight can be met.
The content of the invention
The drawbacks of can not meeting lifting big load weight needs for ring fastening type hoisting chain and carrier bar wafer type chain, this
Utility model provides a kind of compact type chain of lifting big load weight.
To achieve these goals, this utility model Bian takes technical scheme below enforcement：A kind of lifting big load weight
Compact type chain, is made up of some chain links and bearing pin, it is characterised in that：
Described chain link is divided into two parts, and a portion is inner link, and another part is outer link, and inner link is axle,
Outer link is hole, and the inner link in every adjacent two chain links coordinates with outer link gap, and constitutes hinges by bearing pin.
Further, it is axle between outer link to be fixedly connected between the bearing pin and inner link in the hinges
Coordinate with the gap in hole.
Further, it is provided with bushing in the pin shaft hole on the outer link.
Further, solid thickness of the inner link on bearing pin length direction is more than or equal to outer link along bearing pin length
Solid thickness on direction.
This utility model plugs together the inner link in some chain links in outer link, and constitutes several work by bearing pin
Dynamic hinge, can form the lifting chain of a closing.With such chain cuff big load weight, safety and stability reliability.
This utility model has the advantages that reasonable in design, simple structure, easily manufactured, small volume, carries big.
Description of the drawings
Accompanying drawing 1 is front view of the present utility model；
Accompanying drawing 2 is cross section structure diagram of the present utility model.
In accompanying drawing 1,2：1 is chain link, 2 is bearing pin, 3 is suspender, 4 is bushing.
Specific embodiment
Explanation is further explained to this utility model below in conjunction with accompanying drawing：
As shown in accompanying drawing 1,2, chain link 1 is divided into two parts, and a portion is inner link, and another part is outer link, interior
Chain link is axle, and outer link is hole, and the inner link in every adjacent two chain links 1 coordinates with outer link gap, and consists of bearing pin 2
Hinges；To increase the durability of hinge, will be set to be fixedly connected between the bearing pin 2 and inner link in hinges, with
Gap between outer link for axle and hole coordinates；Bushing 4 is provided with pin shaft hole on outer link, so as to rapid wear replacing；Inner link
Solid thickness on bearing pin length direction is more than or equal to solid thickness of the outer link on bearing pin length direction.
This utility model plugs together the inner link in some chain links 1 in outer link, and constitutes several by bearing pin 2
Hinges, can form the lifting chain of a closing.When using, lifting chain is strutted and is enclosed within the suspender 3 of crane, bottom
Cuff big load weight, starting crane can be by weight lifting to setting position.
