Abstract
The invention discloses a lifting appliance with a limiting function. The lifting appliance with the limiting function comprises a sling (1), a connecting part (2) hung on the sling (1), and a hook (3) fixedly connected to the connecting part (2). An A limiting block (41) and a B limiting block (42) made of hard alloy are welded on an inner side wall of the hook (3); non-skid threads (5) are respectively arranged on side walls of the A limiting block (41) and the B limiting block (42). With the structure, the limiting parts provided by the invention can limit displacement of a lifting lug or a steel wire rope in the hook (3), so that the lifting lug or the steel wire rope is prevented from falling off from the hook (3), and then an object to be lifted is prevented from falling off during the lifting process.
Description
Technical field
The present invention relates to five metals suspender field, specifically, be the suspender of a kind of band limit function.
Background technology
Suspender is as a kind of instrument, and use frequency in daily life is the highest, and especially in lifting work, suspender is requisite a kind of instrument, during use, need to be suspended on suspender by suspended object.Suspender of the prior art, substantially can meet lifting requirements of one's work, for security consideration, a lot of suspenders are provided with tongue piece at hooking slits, for preventing suspended object from coming off from suspender, but not ensuring that when there is emergency, tongue piece can not come off by bumping post suspended object completely.
Summary of the invention
It is an object of the invention to provide the suspender of a kind of band limit function, its simple in construction, hook arranges limiting component, solve the problems referred to above.
The present invention is achieved through the following technical solutions: the suspender of a kind of band limit function, the connecting portion including hoist cable, being suspended on hoist cable and fix the hook being connected with connecting portion, also includes the limiting component being fixedly connected on hook sidewall.
Further, described limiting component includes A limited block and B limited block, and A limited block is arranged on the position on hook medial wall away from hooking slits, and B limited block is arranged on Gua Gou medial wall the position near hooking slits.
Further, it is provided with for anti-skidding non-skid thread (5) on the surface of described A limited block and B limited block.
Further, the bar number of described non-skid thread is 5-6 bar.
Further, described limiting component uses hard alloy to make.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention uses the structure arranging limiting component on hook sidewall, when suspended object by hanger or steel wire hang on hook time, limiting component can limit the displacement that hanger or steel wire rope move along hook medial wall, thus prevent the risk that hanger or steel wire rope come off at hooking slits and suspended object is dropped, and then improve the safety of the present invention；
(2) limiting component in the present invention includes the B limited block near hooking slits and the A limited block of principle hooking slits, A limited block and B limited block act on jointly, not only limit hanger or steel wire rope towards the displacement at hooking slits, the most also hanger or steel wire rope are limited towards the displacement within hook, thus prevent when jolting, hanger or steel wire rope depart from hook towards internal movement of hook and suspended object are dropped, and then improve the safety of the present invention；
(3) present invention is provided with 5-6 bar non-skid thread on the surface of limiting component, when hanger or steel wire rope contact with limiting component when, anti-skidding effect can be played, make because of skidding hanger or steel wire rope come off at hook the risk causing suspended object to drop after avoiding hanger or steel wire rope to contact with limiting component further, thus improve the safety of the present invention；
(4) limiting component of the present invention uses hard alloy to be made, due to hard alloy have that hardness is high, wear-resisting, intensity and toughness advantage preferable, heat-resisting, corrosion resistant, be not easy in use with fracture during the collision of hanger or steel wire rope, and then extend the physical life of the present invention, improve the safety of the present invention simultaneously.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment:
As shown in Figure 1, in the present embodiment, a kind of suspender of band limit function, the connecting portion 2 including hoist cable 1, being suspended on hoist cable 1 and the hook 3 that be connected fixing with connecting portion 2, the medial wall of hook 3 is fixedly connected with limiting component, limiting component includes A limited block 41 and B limited block 42, hook 3 is shaped to circular arc, limiting component uses the mode of welding to be fixedly connected on hook 3, wherein A limited block 41 is welded on away from the medial wall of hook 3 linking up with 3 openings, and B limited block 42 is welded on the medial wall of the hook 3 of hook 3 openings.
A limited block 41 and B limited block 42 in the present embodiment all uses hard alloy to process, preferred forms as the present embodiment, A limited block 41 and B limited block 42 all does squarely, and the arc identical with hook 3 radians is set in the one end contacted with hook 3, in order to can be preferably welded on by limiting component on hook 3 welding when.
In the present embodiment, as shown in Figure 2 and Figure 3, A limited block 41 and B limited block 42 is provided with non-skid thread 5, and the quantity of non-skid thread 5 is 6.
During use, the hanger or steel wire rope that hang suspended object are placed in the space of A limited block 41, B limited block 42 and hook 3 formation by user；When taking off, needing when linking up with 3 not load, the hanger or steel wire rope that hang suspended object are taken off by user.
The above, be only presently preferred embodiments of the present invention, and the present invention not does any pro forma restriction, every above example is made according to the technical spirit of the present invention any simple modification, equivalent variations, within each falling within protection scope of the present invention.
