Abstract
This utility model relates to a kind of Novel hand calabash, it is characterised in that described chain block includes fixed hook, lifting hook, and is arranged on the manual turntable between fixed hook and lifting hook, and described manual turntable connects lifting by lifting slide fastener and links up with.This technical scheme overall construction design is reasonable, ingenious, simple to operate, in that context it may be convenient to lifting, stretching and loose unloading, very convenient.
Description
Technical field
This utility model relates to a kind of chain block, particularly relates to a kind of Novel hand calabash, belongs to weight hanging structural device technical field.
Background technology
Chain block makes again chain block, jin not fall, and is a kind of Manual hoisting simple, easy to carry machinery that uses, also referred to as " ring-chain hoist " or " jack ".It is applicable to the short distance handling of mini-plant and goods, and lifting capacity is usually no more than 100T.The enclosure material of chain block is superior alloy steel, firm wear-resisting, and security performance is high.When chain block is lifted up weight, drop manual-chain clockwise, bangle wheel rotates, and drops counterclockwise and pull chain during decline, Brake Block separates with brake block, ratchet is static under the effect of ratchet, and five tooth major axis drive chain hoist wheel reverse direction operation, thus steadily decline weight.Cast iron pipe docking boil on the nape opposite the mouth operation extension set tool boil on the nape opposite the mouth and artificial boil on the nape opposite the mouth, machinery boil on the nape opposite the mouth speed is fast, but the scope of operation is required height, it is desirable to have enough places.Artificial docking boil on the nape opposite the mouth is primarily directed in narrow field, machinery can not enter place and implement the situation of construction operation, and segmentation suppresses the pipeline of reserved non-construction section and meets and discusses situation, artificial docking boil on the nape opposite the mouth depends on chain block and pulls cast iron pipe enforcement docking boil on the nape opposite the mouth, it is slow that this operation installs cast iron pipe progress, inefficiency, therefore, solves above-mentioned technical problem in the urgent need to a kind of new technical scheme.
Summary of the invention
This utility model is just for technical problem present in prior art, it is provided that a kind of Novel hand calabash, this technical scheme overall construction design is reasonable, ingenious, simple to operate, in that context it may be convenient to lifting, stretching and loose unloading, very convenient.To achieve these goals, the technical solution adopted in the utility model is, a kind of Novel hand calabash, it is characterized in that, described chain block includes fixed hook, lifting hook, and it being arranged on the manual turntable between fixed hook and lifting hook, described manual turntable connects lifting by lifting slide fastener and links up with.
As a kind of improvement of the present utility model, described manual turntable includes round turntable frame, is provided with rotatable support in described round turntable frame, and described rotatable support is welded on turntable mounting.
As a kind of improvement of the present utility model, described round turntable frame chooses the round steel of Φ 16mm, a diameter of 250mm of whole round turntable.
Relative to prior art, the beneficial effects of the utility model are as follows: 1) whole Technical Design is ingenious, rational in infrastructure, 2) steering wheel manually rotated in welding in this technical scheme just can drive chain block to make chain hoist wheel operate, and reaches the effect of lifting, stretching, loose unloading；3) this technical scheme reaches to drive chain hoist wheel effect by rotating round steel steering wheel, after removing manual-chain, former comparison heavy chain block deadweight alleviated, alleviate carrying burden, avoiding manual-chain simultaneously after removing manual-chain during construction and like phenomenon of tiing a knot, and it is fast to rotate round steel manual turntable speed, lifting, stretching, loose unloading speed have had and have been obviously improved, simultaneously when using this device, the fine setting up and down of chain hoist wheel can also realize by rotating round steel manual turntable；4) this technical scheme cost is relatively low, and can reuse, and reduces entreprise cost further, it is simple to large-scale popularization and application.

Detailed description of the invention
In order to deepen understanding and cognition of the present utility model, below in conjunction with the accompanying drawings this utility model it is further described and introduce.
Embodiment 1 :See Fig. 1-Fig. 3, a kind of Novel hand calabash, described chain block includes fixed hook 1, lifting hook 3, and it is arranged on the manual turntable 4 between fixed hook and lifting hook, described manual turntable 4 connects lifting hook 3 by lifting slide fastener 2, described manual turntable includes round turntable frame 5, is provided with rotatable support 6 in described round turntable frame, and described rotatable support is welded on turntable mounting 5.
Embodiment 2 :Seeing Fig. 1-Fig. 3, as a kind of improvement of the present utility model, described round turntable frame 5 chooses the round steel of Φ 16mm, a diameter of 250mm of whole round turntable.Remaining structure is identical with embodiment 1 or 2 with advantage.
Work process: see accompanying drawing 3, choose Φ 16 round steel be manual turntable make material, the wherein a diameter of 250mm of finished product round steel manual turntable, in manual turntable round steel with the connection of round steel for welding.See accompanying drawing 2, 3, ductile iron pipe manually docks boil on the nape opposite the mouth construction needs two these products, before ductile iron pipe docks, by to connecting and needing on the cast iron pipe of docking each steel cable 7 on bolt, and allow it fix, then 3 suspension hooks are linked up with in fixed hook 1 and the lifting of this product, after being hung in guaranteeing that this product suspension hook of cast iron pipe both sides and hoisting-chain suspension hook hang up properly on the steel wire rope connecting on cast iron pipe and on the steel wire rope of undocked cast iron pipe, both sides are simultaneously with artificial rotation manual rotating disk, its hoisting chain is allowed tightly to receive, until ductile iron pipe reaches dimension line to pipe, reach pipe effect.
Technical characteristic described in embodiment 2 and embodiment 1 can also be combined the embodiment that formation is new according to practical situation by this utility model.
It should be noted that above-described embodiment, be not used for limiting protection domain of the present utility model, equivalents done on the basis of technique scheme or replacement each fall within this utility model scope of the claimed protection.
