Abstract
The utility model discloses a pretensioning type ton-bag lifting tool, which aims at providing a pretensioning type ton-bag lifting tool which can avoid hook releasing phenomena when ton-bag goods is loaded and unloaded and can improve the safety and the production efficiency. The pretensioning type ton-bag lifting tool comprises a lifting armored rope, a lifting hook, an extension spring and two safety buckles, wherein a first lifting sleeve and a second lifting sleeve are arranged on two ends of the lifting armored rope, a lifting hook is connected in the first lifting sleeve, two ends of the extension spring are connected with the first safety buckle and the second safety buckle with openings, the first safety buckle is connected with the first lifting sleeve, and the second safety buckle is connected with the second lifting sleeve. The length ratio between the extension spring and the lifting armored rope is 5:8 to 7:8. The pretensioning type ton-bag lifting tool utilizes the telescopic characteristics of the extension spring through combining the lifting armored rope with the extension spring, when the lifting tool is lifted well and loosened, the lifting hook can tightly hook ton bags and can avoid the hook releasing phenomena, thereby, loading workers do not need to hold the lifting hook until the ton bags are lifted, the safety is greatly improved, and the production efficiency is also greatly improved.
Description
Technical field
The utility model relates to a kind of prestretching type ton bags hanging tool.
Background technology
At present, the lifting device of the goods class use of loading and unloading jumbo bag is made up of lifting steel wire rope and suspension hook.Be respectively arranged with the lifting cover at the two ends of steel wire rope, be connected with suspension hook in the lifting cover of an end, the lifting cover of the other end is used for being connected with crane.Owing to can not fill safety buckle on the suspension hook of the goods class of loading and unloading jumbo bag, the phenomenon that usually can break off relations has the hidden danger that security incident takes place.For this reason, need the workman to buttress suspension hook, workman's safety is threatened up to the ton bag of slinging at the goods time-like of stevedore ton bag.And, often break off relations, need the workman repeatedly hanging hook also reduced production efficiency.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of stevedore ton bag goods time-like that can make to avoid the phenomenon that breaks off relations, improving the pre-pull-type ton bag lifting device of safety and production efficiency.
The utility model is achieved through the following technical solutions:
A kind of prestretching type ton bags hanging tool, it is characterized in that, comprise lifting steel wire rope, suspension hook, extension spring and two safety buckles, be respectively arranged with the first lifting cover and the second lifting cover at the two ends of lifting steel wire rope, be connected with suspension hook in the described first lifting cover, the two ends of extension spring are connected with respectively with first safety buckle of opening and second safety buckle, and first safety buckle is connected with the first lifting cover, and second safety buckle is connected with the second lifting cover.
Described extension spring is 5:8～7:8 with the Length Ratio of lifting steel wire rope.
The utlity model has following technique effect:
Pre-pull-type ton bag lifting device of the present utility model will be by lifting combining of steel rope and extension spring, utilize the expansion performance of extension spring, when hanging up properly when unclamping, suspension hook will tightly tangle the ton bag, avoid producing the unhook phenomenon, buttress suspension hook up to the ton bag of slinging, improved safety greatly thereby the alongshoreman is not spent, and, also improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model prestretching type ton bags hanging tool.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described in detail.
Fig. 1 is the structural representation of the utility model prestretching type ton bags hanging tool, comprise lifting steel wire rope 7, suspension hook 6, extension spring 3 and two safety buckles 2,4, be respectively arranged with the first lifting cover, the 5 and second lifting cover 1 at the two ends of lifting steel wire rope 3, be connected with suspension hook 6 in the first lifting cover 5, the two ends of extension spring 3 are connected with respectively with first safety buckle 4 of opening and second safety buckle 2, first safety buckle 4 is connected with the first lifting cover 5, and second safety buckle 2 is connected with the second lifting cover 1.
Wherein, the length of extension spring is less than the length of lifting steel wire rope, when the ratio of Length Ratio of extension spring and lifting steel wire rope is big, then can break off relations.Ratio hour produces again the extension spring fracture, the consequent strength stevedore that injures easily, and therefore selecting extension spring and the Length Ratio of lifting steel wire rope is 5:8～7:8, wherein, the length of steel wire rope does not comprise the length that the first lifting cover and second lifting are overlapped.For the length of selecting extension spring provides foundation, extension spring length should reduce between the 40cm-90cm, such as the extension spring of 1.5 meters of 2.4 meters selection of steel on the basis of rope capacity.
During use, by the opening on first safety buckle and second safety buckle, respectively first safety buckle and second safety buckle are inserted in the first lifting cover and the second lifting cover.During lifting, be hung on the jumbo bag steel wire rope is stretching, because the effect of extension spring, will tightly tangle jumbo bag and can not produce the unhook phenomenon when hanging up properly when unclamping suspension hook.
Although relate to a pre-pull-type ton bag lifting device and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
Claims (2)
1, a kind of prestretching type ton bags hanging tool, it is characterized in that, comprise lifting steel wire rope, suspension hook, extension spring and two safety buckles, be respectively arranged with the first lifting cover and the second lifting cover at the two ends of lifting steel wire rope, be connected with suspension hook in the described first lifting cover, the two ends of extension spring are connected with respectively with first safety buckle of opening and second safety buckle, and first safety buckle is connected with the first lifting cover, and second safety buckle is connected with the second lifting cover.
2, prestretching type ton bags hanging tool according to claim 1 is characterized in that, described extension spring is 5:8～7:8 with the Length Ratio of lifting steel wire rope.
