Description

Explosion proof type gram swings double hook

Technical field

The utility model relates to a kind of suspension hook of reusing, and is specifically related to a kind of explosion proof type gram and swings double hook.

Background technology

In lifting industry, suspension hook is ubiquitous, such as bridge-type, transfer crane, the suspension hook of tradition bridge crane, gantry crane mostly is single hook, sling weight often because Slip Hook phenomenon appears in suspension hook built on the sand, and the lighter causes hung article to damage, and delays the duration, even can there is casualty accident time serious, there is very large potential safety hazard.In order to strengthen stability and the safety of suspension hook, there is double-hung, see Fig. 1, shown in Fig. 2, namely the things such as lifting rope are sling, relative to single hook through two suspension hooks simultaneously, add the area of contact of lifting rope and suspension hook, suspension hook supports more stable, and the radian that lifting rope is sling is excessively more natural, but present double hook still exists following problem, one be sling thing and suspension hook adhesive ability inadequate, easily swing when slinging, still there is very large potential safety hazard, occur the problem of coming off easily.Although now part suspension hook opening part is provided with buckle, be easy to come off, and workman will sling after thing hangs up, workman is easy to forget to detain, and practicality is not strong.Two is can produce Relative friction between suspension hook and steel rope, and excessive being easy to of rubbing causes spark, and in explosive gas atmosphere or combustible dust environment, the explosion caused danger of possibility, so suspension hook anti-" sparking " is also a current very important technical matters.

Utility model content

The purpose of this utility model is for the deficiencies in the prior art part, a kind of explosion proof type gram is provided to swing double hook, this Suspension hook structure simplicity of design, when slinging, lifting rope is hang, relative to direct flat extension mode, with suspension hook strong adhesion, not easily occur swinging, in addition, this suspension hook also has anti-" sparking " function.

Technical scheme: a kind of explosion proof type gram swings double hook, comprise hook body, the left hook of one and right hook is disposed with bottom hook body, described left hook and right hook are symmetrical arranged, described hook body skin is sprayed with anti-" sparking " layer of one deck, the hook body on left hook and right hook top is also provided with reclinate arc shaped hook, and form the container cavity that is held lifting rope between described arc shaped hook and left and right hook, described container cavity diameter is less than sash-line diameter.

Preferably, described anti-" sparking " layer is sprayed by corrosion-resistant steel or copper material and forms.

Preferably, the reclinate angle of described arc shaped hook is 45 degree.

Preferably, left hook and right hook K/UP angle are 90 degree.

The beneficial effects of the utility model: the utility model is on the basis of traditional double hook, an arc shaped hook is set up on hook top, and the container cavity diameter that arc shaped hook and bottom catch are formed is less than sash-line diameter, when hooking, first lifting rope is hung over arc shaped hook top, then pull-up lifting rope presses down, be squeezed in container cavity, when now lifting rope is through hook, curvedly press down trend, through time and have certain waveform tortuous, make to press tighter and tighter between lifting rope and suspension hook slinging under thing Action of Gravity Field, and lifting rope is hang, can effectively prevent traditional double hook from directly hanging up flat for lifting rope, lifting rope and suspension hook adhesive ability weak, when slinging easily there is relative sliding in lifting rope and suspension hook, lifting rope is caused to swing, the problem of thing instability of slinging.So the suspension hook of this patent can overcome swing by actv., this suspension hook skin is sprayed with anti-" sparking " layer in addition, and during use, can not produce spark because of external world's friction or collision, have explosion prevention function, use safety coefficient is high.

Accompanying drawing explanation

Fig. 1 is traditional double hook block hook structure schematic diagram;

Fig. 2 is the using state figure of Fig. 1,

Fig. 3 is that the utility model anti-" sparking " type gram swings double hook structural representation;

Fig. 4 is the using state figure of Fig. 3.

Number in the figure, 1 is hook body, and 2 is left hook, and 3 is right hook, and 4 is suspension hook coupling end, and 5 is lifting rope, and 6 is arc shaped hook.

Detailed description of the invention

Below in conjunction with specific embodiment, the utility model is described in further detail.

Embodiment 1: a kind of explosion proof type gram swings double hook, see Fig. 1, comprise hook body 1, left hook 2 and the right hook 3 of one is disposed with bottom hook body 1, described left hook 2 and right hook 3 are symmetrical arranged, described hook body 1 skin is sprayed with anti-" sparking " layer of one deck, and this anti-" sparking " layer can be corrosion-resistant steel or copper material spraying.Owing to rising, to reuse suspension hook bearing capacity larger, larger with the friction force of contactant, along with relative movement is easy to produce spark, cause danger, at present, anti-" sparking " problem of suspension hook is unmanned so far to be solved, the present embodiment is sprayed with anti-" sparking " coating of one deck at suspension hook skin, suspension hook and to sling between thing and can not produce spark because rub again, relievedly can use, ensure that the safety that suspension hook uses.The hook body 1 on left hook 2 and right hook 3 top is also provided with reclinate arc shaped hook 6, and form the container cavity that is held lifting rope between described arc shaped hook 6 and left and right hook, described container cavity diameter is less than sash-line diameter.

The using state of suspension hook as shown in Figure 4, lifting rope first arcuately hook 6 top is hung up, and then hauls in the middle part of lifting rope and presses down, squeezed by lifting rope in container cavity, because container cavity diameter is less than normal, after being squeezed in by lifting rope from indentation, there, can ensure the impaction state of lifting rope at container cavity, arc shaped hook 6 extrudes lifting rope downwards, under the effect of thing gravity of slinging, lifting rope is sagging, press down, and not easily occurs breakking away, swinging, ensure that the stability of thing of slinging between lifting rope and suspension hook.Left hook and right hook K/UP angle are preferably 90 degree, and the reclinate angle of arc shaped hook is preferably 45 degree.The container cavity in this angle besieged city, encirclement lifting rope that can be compacter, prevents lifting rope from breakking away, swings.
