Abstract

A cup joint type lifting hook comprises a lifting hook body (1). The lifting hook body (1) is provided with a hook mouth (3) which is sleeved from the end of a joist steel (2) and used for craning the joist steel, the shape and the size of the hook mouth (3) are matched with the shape and the size of a horizontal plate (2.1) of the joist steel (2), and the opening width of the hook mouth (3) is greater than the thickness of a vertical plate (2.2) of the joist steel (2). A hook beam (4) of the lifting hook body (1) is provided with a main lifting hole (4.1) used for the craning of a main lifting hook of a joist barrow, the hook beam (4) is further respectively provided with two pairs of lifting holes (4.2) used for the craning of two pairs of lifting hooks of the joist barrow, and the two pairs of lifting holes (4.2) are symmetrically located at two sides of the main lifting hole (4.1). The hook mouth of the cup joint type lifting hook can hook a horizontal plate of a large joist steel and safe lifting can be carried out.

Description

Socket type suspension hook

Technical field:

The utility model relates to a kind of suspender that is used to lift by crane large-scale I-beam section, specifically is a kind of socket type suspension hook.

Background technology:

A kind of large-scale I-beam section as shown in fig. 1, this I-beam section is spliced by up and down two horizontal plates and a vertical plate, and overall weight is at least more than 30～50t.Because of the thickness of two horizontal plates of the I-beam section of the type thicker; The mouth of hook that adds general suspension hook be in the shape of the letter V and opening less; The horizontal plate that the mouth of hook of suspension hook can not hook I-beam section during lifting (that is to say that I-beam section is too thick because of horizontal plate; Horizontal plate can not be put in the mouth of hook of suspension hook), can't lift by crane.

The utility model content:

The utility model technical issues that need to address are: the horizontal plate that provides a kind of mouth of hook can hook large-scale I-beam section, the socket type suspension hook that can lift by crane.

For solving the problems of the technologies described above; The utility model adopts a kind of like this socket type suspension hook; It comprises hook, and described hook is provided with from the I-beam section end and is inserted in to lift by crane the mouth of hook of I-beam section, and the horizontal plate of the shape of the described mouth of hook, size and I-beam section matches; The A/F of the described mouth of hook is greater than the thickness of the vertical plate of I-beam section; The hook beam of described hook is provided with the main hanging hole that is used for purlin car owner's suspension hook lifting usefulness, also is respectively equipped with the two secondary lifting hole(eyelet)s that are used for purlin car two secondary suspension hook lifting usefulness on the described hook beam, and described two secondary lifting hole(eyelet) symmetries are positioned at the both sides of main hanging hole.

The cross-sectional plane of the described mouth of hook is T-shaped.

The utility model compared with prior art; Have the following advantages: be inserted in to lift by crane the mouth of hook of I-beam section because hook is provided with from the I-beam section end, the horizontal plate of the shape of the mouth of hook, size and I-beam section matches, and the A/F of the mouth of hook is greater than the thickness of the vertical plate of I-beam section; Add and on the hook beam, be provided with main hanging hole and two secondary lifting hole(eyelet)s; Like this when lifting, be inserted in the suspension hook an of the type respectively in the end of I-beam section, and main hanging hole and secondary lifting hole(eyelet) that the main suspension hook and the secondary suspension hook of purlin car hooked suspension hook respectively; Just can realize safe lifting, and the lifting process is steadily reliable.

As improvement, the cross-sectional plane of the described mouth of hook is T-shaped, that is to say that the T shape mouth of hook is simple in structure, easy to process.

Description of drawings:

Fig. 1 is the running condition structural representation of the socket type suspension hook of the utility model.

Fig. 2 is the structure for amplifying scheme drawing of the socket type suspension hook of the utility model among Fig. 1.

Shown in the figure: 1, hook, 2, I-beam section, 2.1, horizontal plate, 2.2, vertical plate, 3, the mouth of hook, 4, the hook beam, 4.1, main hanging hole, 4.2, secondary lifting hole(eyelet).

The specific embodiment:

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.

As depicted in figs. 1 and 2, the socket type suspension hook of the utility model, it comprises hook 1, and described hook 1 is provided with from I-beam section 2 ends and is inserted in to lift by crane the mouth of hook 3 of I-beam section, and the cross-sectional plane of this mouth of hook 3 is T-shaped, that is to say that this mouth of hook 3 is the T shape mouth of hook.The horizontal plate 2.1 of the shape of the described mouth of hook 3, size and I-beam section 2 matches, and the A/F of the described mouth of hook 3 is greater than the thickness of the vertical plate 2.2 of I-beam section 2.

The hook beam 4 of described hook 1 is provided with the main hanging hole 4.1 that is used for purlin car owner's suspension hook lifting usefulness.Also be respectively equipped with the two secondary lifting hole(eyelet)s 4.2 that are used for purlin car two secondary suspension hook lifting usefulness on the described hook beam 4.Described two secondary lifting hole(eyelet) 4.2 symmetries are positioned at the both sides of main hanging hole 4.1.

During lifting; Be inserted in the socket type suspension hook an of the utility model toward the two ends of I-beam section respectively, and, just can realize safe lifting main hanging hole and two secondary lifting hole(eyelet)s that the main suspension hook and the two secondary suspension hooks of purlin car hook socket type suspension hook respectively; Whole lifting process is steadily reliable, safe.

Claims
