Abstract

The utility model discloses a six-claw chain rotatable lifting appliance which comprises a lifting ring, a lifting hook nut, a thrust bearing, a lifting scaffold beam, lifting chains, connecting rings and an eye sling hook. The lifting appliance is completely formed through forging, a rod part of the lifting ring penetrates into the lifting scaffold beam, the thrust bearing is placed in a bearing chamber, the lifting hook nut is in threaded connection with the lifting ring, and then a lock bolt is screwed on. The lifting appliance disclosed by the utility model is good in structure stress, is provided with the variable even chains, and is good in operation balancing and stability; the chains are not twisted together, and can rotate at 360 degrees with the bearing; the lifting appliance is large in bearing capacity, saves a lot of labor, is economic and adaptive, and is short in manufacturing cycle; by virtue of the lifting appliance, a whole lifting operation is safe and reliable.

Description

A kind of six dog chain bar Rotatable slings

Technical field

The utility model relates to the Current Collector Sleave of lifting in a kind of production and the transportation, especially a kind of six dog chain bar Rotatable slings.

Background technology

There are many undesirable elements in round bale dress object, round can body, cell body etc. in hoisting process at present; Wanting to rotate the lifting thing, mostly is to rotate the traveling crane gib head of hanging above to finish, and chain also is twisted together easily; Again aerial degree of freedom balance and the extremely difficult control of stability after slinging, again owing to be subjected to the impact of human element and action harmony, hang easy and other object collision of loading, thereby make troubles even danger for lifting, bring certain hidden danger certainly will for the person and product safety.

The utility model content

The purpose of this utility model provides a kind of six dog chain bar Rotatable slings, structure stress is good, the operation balance and have good stability, load-carrying capacity is large, chain can be along with 360 ° of rotations of bearing, save a large amount of labour powers, economic and practical, and can make by operating needs the Current Collector Sleave of multiple even number form, make whole lifting operation safe and reliable.

The technical scheme that its technical matters that solves the utility model adopts is as follows:

The utility model provides a kind of six dog chain bar Rotatable slings, comprise: suspension ring, hook nut, thrust baring, hanging scaffold crossbeam, chain sling, coupling link, eye suspension hook, described suspender is forging and molding, suspension ring bar section penetrates the hanging scaffold crossbeam, put into thrust baring at bearing chamber, hook nut is threaded with suspension ring, the lock bolt of screwing on.

Described chain number is variable any even number, can be along with 360 ° of rotations of bearing.

Described chain is stuck in the suitable position of hanging scaffold crossbeam, uses the bearing pin captive joint.

The utility model structure stress is good, the operation balance and have good stability, load-carrying capacity is large, and can make by operating needs the Current Collector Sleave of multiple even number form, makes whole lifting operation safe and reliable.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below by Figure of description, further set forth the utility model;

According to shown in Figure 1, a kind of six dog chain bar Rotatable slings, comprise: suspension ring 1, hook nut 4, thrust baring 3, hanging scaffold crossbeam 2, chain sling 5, coupling link 6, eye suspension hook 7, described suspender is forging and molding, suspension ring 1 bar section penetrates hanging scaffold crossbeam 2, put into thrust baring 3 at bearing chamber, hook nut 4 is threaded with suspension ring, the lock bolt of screwing on, chain sling 5 numbers are variable any even number, can be along with 360 ° of rotations of bearing, six chain slings 5 are stuck in the suitable position of hanging scaffold crossbeam 2, use the bearing pin captive joint.

In specific works, link eye suspension hook 7 below the suspender, be applicable to lift by crane the suspended objects such as round bale dress object (sugarcane, bamboo), round can body, square groove and circular groove, crane hook hangs the suspension ring 1 on this suspender, tangle respectively the suspension centre (gudgeon or ring-type) of suspended object with six eye suspension hooks, steadily safety is finished lifting operation.

For example: for shipment more easily, the lifting thing is provided with multidirectional groove, and the groove of each direction is equipped with different objects, wants to stand in the people of different directions, the object of dress different directions, and this suspender just can be realized; Because in hanging scaffold crossbeam 2 and the hook nut 4 thrust baring 3 is housed, expect the object of different directions, chain sling 5 can along with 360 ° of rotations of bearing, reach required requirement.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
