Abstract
The utility model discloses a portable lifting appliance, comprising a hanging shaft of which one end is connected with a tapered screw rod, wherein a handle nut which is movably connected with the tapered screw rod is arranged on the hanging shaft, an elastic tooth-shaped expansion joint is arranged outside the bottom of the tapered screw rod, and the other end of the hanging shaft is connected with a lifting hook of a crane. Compared with the prior art, the portable lifting appliance is safe, reliable, convenient and efficient, and has high transportation efficiency, therefore, the portable lifting appliance has a wide application prospect.
Description
Technical field
The utility model relates to a kind of lifting appliance, specifically, relates to a kind of portable lifting appliance.
Background technology
In plastic sheet or processing film field, when the sheet material of rolling or film are moved away from the production scene, adopt the lifting of lifting rope or suspender belt to move (specifically as shown in Figure 1) mostly.This mode of moving has following several shortcoming:
1, influences the product appearance quality: the surface generation of product is frayed;
2, there is potential safety hazard: when tying up product, if tie up overbalance or misoperation, can make product landing in the process of lifting cause safety misadventure;
3, influence handling efficiency: lifting rope, suspender belt are when tying up product, and time and effort consuming not only influences work efficiency but also increase working strength.
The utility model content
At the problems referred to above that prior art exists, the purpose of this utility model provides a kind of safe, efficient, stable portable lifting appliance.
For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is as follows:
A kind of portable lifting appliance, comprise that an end is connected with the hanging axis of a taper screw mandrel, described hanging axis is provided with a handle nut that flexibly connects with described taper screw mandrel, and described taper screw mandrel bottom is outer is furnished with the elasticity profile of tooth head that expands, and the other end of described hanging axis links to each other with hoist lifting hook.
Preferably, be provided with a spring between described handle nut and described taper screw mandrel, be used for stablizing being connected and force balance between handle nut and taper screw mandrel.
More preferably, described spring overcoat has a spring compressor, for the protection of spring.
More preferably, the bloated head of described elasticity profile of tooth is three-pawl type.
More preferably, the bloated periphery of described elasticity profile of tooth is provided with serration, is used for pricking to advance to wait to hang product core pipe inner arm with the lifting product.
Compared with prior art, the portable lifting appliance that provides of the utility model has following technological merit:
1, safe and reliable: by the elasticity profile of tooth expand crown on the head prick into product core pipe made of paper inner arm can landing;
2, convenient and swift: this hoisting device hangs on the hoist lifting hook always, need not take off, with getting off to finish the action of dress hoisting device on the crane;
3, improve handling efficiency: when adopting this portable hoisting device lifting product, bloated head puts in the bloated head of core paper → expansion → lifting, and every lifting one volume product took time about 30 seconds; Compare and adopt traditional lifting rope, suspender belt, during the lifting product, dress with → tie up → be linked with → lifting more than 2 minutes of lift by crane rolls up product, required time greatly reduces, more economical and efficient.
Therefore its application prospect is very wide.
Description of drawings
Fig. 1 is the structural representation of lifting appliance commonly used in the prior art;
The structural representation of the portable lifting appliance that Fig. 2 provides for the utility model;
Among the figure: 1, hoist lifting hook, 2, lifting rope or suspender belt, 3, product to be hung;
21, hoist lifting hook, 22, the handle nut, 23, spring, 24, spring compressor, 25, the elasticity flute profile head that expands, 26, the taper screw mandrel, 27, product to be hung, 28, core pipe made of paper.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing to the utility model do further in detail, intactly explanation.
The structural representation of the portable lifting appliance that Fig. 2 provides for the utility model, this portable lifting appliance comprises that an end is connected with the hanging axis of a taper screw mandrel as shown in Figure 2, described hanging axis is provided with a handle nut that flexibly connects with described taper screw mandrel, be furnished with the bloated head of an elasticity profile of tooth outside the described taper screw mandrel bottom, the other end of described hanging axis links to each other with hoist lifting hook; Be provided with a spring between described handle nut and described taper screw mandrel, be used for stablizing being connected and force balance between handle nut and taper screw mandrel; Described spring overcoat has a spring compressor, for the protection of spring; The described elasticity profile of tooth head that expands is preferably three-pawl type, and periphery is provided with serration, is used for pricking to advance to wait to hang product core pipe inner arm with the lifting product.
The principle that this portable lifting appliance adopts the conehead screw mandrel that the bloated head of three-pawl type elasticity profile of tooth is expanded, shunk is carried out the lifting carrying to product, and is specific as follows:
1, lifting product: the bloated head of hoisting device is put in the product core pipe made of paper, be rotated in the forward the handle nut, the conehead screw mandrel rises, and the bloated head of elasticity profile of tooth expands outwardly, and the crown of the bloated head of elasticity profile of tooth is pricked the core pipe inner arm of into waiting to hang product, just can lift by crane product;
2, take out hoisting device: by lifting machine will product be hung move to required placement or the position of depositing after, contrarotation handle nut, the conehead screw mandrel glides under the effect of spring, the elasticity profile of tooth head that expands inwardly shrinks, crown breaks away from the core pipe just can take out hoisting device; Finish and wait to hang product lifting displacement and deposit process.
Be necessary at last in this explanation to be: above embodiment only is used for the technical solution of the utility model is done explanation in further detail; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement and adjustment that those skilled in the art makes according to foregoing of the present utility model all belong to protection domain of the present utility model.
