Abstract

The invention relates to a hook assembly, which belongs to the technical field of winching facilities. The lifting hook device comprises a hook body and a hook rod extending on the hook body, whereinthe cross section at the position of the hook end of the hook body is in a circular shape; the cross section at the bottom of the hook body is in a shape of a saddle; and the cross section at the hookback of the hook body is in a shape of the saddle. The hook assembly has the advantages of improving the contacting effect of the hook body and a lifting rope or similar tie-off pieces to embody safety, and not only further improving the strength of the hook body, but also reasonably saving materials due to the reasonable selection of the shapes of the cross sections at the three different positions of the hook body.

Description

Cargo hook gear

Technical field

The invention belongs to handling facility technology field, be specifically related to a kind of cargo hook gear, be applied to occasions such as boats and ships, harbour, harbour, industrial and mineral.

Background technology

The structure of cargo hook gear seems to be simple, constitute by the shank that extends on coupler body and the coupler body, to live in people the structural strength of cargo hook gear is only paid attention to material, thereby the self structure of coupler body attached undue importance to one thing to the neglect of the other to some extent, yet the applicant thinks, cross sectional shape for each position of coupler body carries out appropriate design, and not only can further strengthen the intensity of coupler body and improve safety, but also economical with materials reasonably.Technical scheme described below is based on producing under this background.

Summary of the invention

Task of the present invention is to provide a kind of coupler body the rational in infrastructure and cargo hook gear that helps to improve intensity, embody safety and economical with materials.

Task of the present invention is finished like this, a kind of cargo hook gear, and it comprises coupler body and the shank that extends on coupler body, the shape of cross section of the chimoto position of described coupler body is circular; The shape of cross section of the position, hook bottom of described coupler body is a saddle-shaped; The shape of cross section at the back position of described coupler body is a saddle-shaped.

In a specific embodiment of the present invention, the bottom of described shank has extended a pivot ear, and this pivot ear is provided with a mouth of hook osed top safety device that is used for described coupler body.

In another specific embodiment of the present invention, the shape of cross section of the bottom of described shank is oval.

Go back in the specific embodiment of the present invention, described safety device comprises bearing pin, spring and retaining tongue, bearing pin is arranged on the described pivot ear, the two ends of spring are nested with the two ends at bearing pin, touch with the retaining whip graft at the middle part of spring, one end hub setting of retaining tongue is at the middle part of bearing pin, and the other end constitutes the free end to described mouth of hook block or unlatching.

The present invention is owing to adopted above-mentioned design, can make coupler body and lifting rope or with similarly be the embodiment safety that is improved of the contacted effect of suspension member, horizontal sanction face shape to three of coupler body different positions has been made choose reasonable, not only can further improve the intensity of coupler body, and economical with materials reasonably.

The specific embodiment

Ask for an interview Fig. 1 to Fig. 5, cargo hook gear comprises coupler body 1 and the custom of extending on coupler body 1 is referred to as the shank 2 of hook handle, by Forging Technology coupler body 1 and hook is processed 2 one, and material preferably adopts DG20Mn.Hook end 11 positions of coupler body 1 promptly constitute by circle shown in Figure 3 corresponding to the shape of cross section of the mouth of hook 14 openings of coupler body 1, and 12 positions are that the shape of cross section of the bottom of the mouth of hook 14 constitutes by saddle-shaped shown in Figure 4 at the bottom of the hook of coupler body 1, this shape also can claim Chinese lute shape, and the shape of cross section at back 13 positions of coupler body 1 constitutes equally by saddle-shaped shown in Figure 5.

Please continue to see Fig. 1 and Fig. 2 and in conjunction with Fig. 6, the bottom of shank 2 extended a pivot ear 21 towards a side of the mouth of hook 14, one safety device 211 is set on pivot ear 21, the bearing pin 2111 of safety device 211 is located on the pivot ear 21, and be nested with two ends at bearing pin 2111 as the two ends of the spring 2112 of safety device 211, the middle part is pasted with retaining tongue 2113 and is touched, the upper end of retaining tongue 2113 is located at the middle part of bearing pin 2111, the lower end of retaining tongue 2113 constitutes free end and corresponding to the mouth of hook 14, is used for to the mouth of hook 14 sealings or unlatching.When keeping off tongue 2113 with hand when a thruster of coupler body 1 is moving, retaining tongue 2113 just overcomes the power of spring 2112 and the mouth of hook 14 is opened, otherwise, when pointing pine from retaining tongue 2113, retaining tongue 2113 is resetted, to the mouth of hook 14 block, so that in the handling process, play the safety control effect by retaining tongue 2113.The bottom of shank 2, more particularly shank 2 constitutes by ellipse shown in Figure 6 with the shape of cross section in abutting connection with the position of coupler body 1.The screw thread 22 of the upper end of shank 2 and matching hole 23 are for connecting usefulness with other parts.

Because technical solution of the present invention made appropriate design to the shape of cross section of the different parts of coupler body 1, so safety and intensity all is able to remarkable improvement, and economical with materials reasonably.
