Abstract

The utility model discloses a rotary lifting appliance which is characterized by comprising a lifting hook for hooking and a hoisting ring matched with the main hook of a crown block; a slowly lowering device is arranged between the lifting hook and the hoisting ring; the slowly lowering device is a screw; a nut matched with the screw is arranged; the upper end of the screw is connected with the hoisting ring; and the exterior of the nut is connected with the lifting hook. The lifting hook can be lifted up and down through an annular round steel bar which is rotationally welded on the nut. When cargo is about to contact the ground, the lowering of the main hook of the crown block is stopped, and frangible cargo can be lowered manually by rotating the annular round steel bar, so that the lowering of the cargo can be controlled better during a lifting process.

Description

Rotary hanger

Technical field

The utility model relates to a kind of suspender, the especially a kind of rotary hanger that can slowly transfer.

Background technology

The general elevator machineries such as overhead traveling crane or hoist that use in producing preparation, article handling process.Article such as, easy fracture frangible in handling land or when contacting the article driving surface, speed and distance that these elevator machineries can not better controlled descend.Even adopt crawl to descend; Only skilled, veteran operative employee; Otherwise also in the decline process, break or strike these article extremely easily, cause the damage of these article, for the safety of goods has increased uncontrollable factor; Not only do idle work in vain, also increased cost.

Summary of the invention

The purpose of the utility model is to provide a kind of rotary hanger, and the handling that cracked article were handled, were prone to this rotary hanger with care to need has remarkable preceence, and manufacture craft is simple, and operative technique requires lower,

For achieving the above object, the technical scheme that the utility model adopted is following:

A kind of rotary hanger comprises being used to hold hanging hook that hangs and the suspension ring that cooperate with the overhead traveling crane main hook, is provided with the slow device of putting between hanging hook and the suspension ring.

Above-mentioned rotary hanger, it is described that slow to put device be a screw rod, cooperates with screw rod to be provided with nut, the upper end connection suspension ring of screw rod, nut connects hanging hook outward.

Above-mentioned rotary hanger is provided with round steel between said nut and the hanging hook, and the outside of nut connects round steel through dowel.

Above-mentioned rotary hanger, described dowel are four, and four dowel annulars are evenly arranged.

The beneficial effect of the utility model shows:

The utility model is expert at and is installed a secondary new suspension hook on car owner's suspension hook additional, and this suspension hook is used for hang weight through hanging hook, articulates through suspension ring and main suspension hook, and setting between the two can slowly discharge the slow device of putting of weight.

This delays puts screw rod and the nut that device can adopt screw thread fit, and screw rod is connected suspension ring and hanging hook respectively with nut, can realize the slow release of weight during use through the rotation of screw thread.

To sum up, the utlity model has following advantage:

1, safe and reliable, can rotate steel ring through manual work just can be fragile goods slowly land ground.

2, simple to operate, dismounting, combination, easy and simple to handle feasible also can be changed slightly, needing weld to use bolted connection instead, carry assembling whenever and wherever possible.

3, practical, can be used for every field such as life, production.For example, the required mouth of a river of large-scale glass, vase, porcelain, the metallurgical production of handling, stopper, strong collision explosives etc.

Description of drawings

Fig. 1 is the utility model master TV structure scheme drawing;

Fig. 2 is the A-A sectional structure scheme drawing of Fig. 1.

The specific embodiment

Come the utility model is described in detail with the specific embodiment below:

A kind of rotary hanger comprises being used to hold hanging hook 4 that hangs and the suspension ring 2 that cooperate with the overhead traveling crane main hook, is provided with the slow device of putting between hanging hook 4 and the suspension ring 2.

The described slow mode of putting has the multiple choices mode, such as screw thread slowly put, hydraulic pressure is slow puts etc.The utility model employing screw thread is slow puts mode, and it comprises a screw rod 1, cooperates with screw rod 1 to be provided with nut 2, and the upper end of screw rod 1 connects suspension ring 2, and nut 3 is outer through round steel 5 connection hanging hooks 4.

The nut 3 outer dowels that pass through connect round steel 5, and described dowel is four, and four dowel annulars are evenly arranged.

Come the utility model is further specified below in conjunction with the course of processing:

Comprise one of M36mm * 500mm STRTHD screw mandrel, screw mandrel top reserve 100mm without car silk, the promise of Φ 10mm round steel do, one on M36mm nut, one of small-sized hanging hook.

1, with behind the M36mm nut screw-in screw mandrel, with several grades of heads of electrical pads, effect is not allow nut to deviate from screw mandrel the screw mandrel lower end.2, not having the silk part on screw mandrel top becomes the suspension ring shape to be welded on the screw mandrel with Φ 10mm round steel circle.3, become the circle shape with Φ 10mm round steel circle, add several sections connection round steel and be welded on the nut both sides.4, become the U type with two sections Φ 10mm round steel circles, fit inside hanging hook, U type two ends are welded on the ring-type round steel.

During use, suspension ring 2 hang on the overhead traveling crane main hook, and small-sized hanging hook 4 tangles goods, during overhead apart from 500mm, can slowly land goods through rotational circle round round steel 5.

Just can realize that through the ring-type round steel of rotating welding on nut controlling suspension hook hoists up and down like this.When the fast kiss the earth of goods, stop the decline of overhead traveling crane main hook, just can artificial landing fragile goods through rotation ring-type steel ring, the controlled ability that descends during the handling of raising goods.
