Description

I The invention relates to hoisting machinery, in particular, load handling devices for goods with rigid eyelets. A load handling device for goods with lugs of predominantly rigid is known, comprising a housing with a slot and a hook in the lower part, a spring-loaded hinged latch for closing the housing slot and an opening of the hook and a limiter for moving the latch. The disadvantage of this device is low reliability and complex construction. The purpose of the invention is to improve reliability and simplify the design. This goal is achieved by the fact that in the load handling device for goods with lugs mainly rigid, containing a housing with a slot and a hook in the lower part, a spring-loaded (hinged) latch. the hook and the movement stop latch, the latter is a flat spring placed in the upper part of the body, and the latch is a three-arm arm, installed with the possibility of interaction of one shoulder alternately obraschennv4i one another internal power metal Nost of the housing, the plate and lug pruzhi hydrochloric cargo and other cargo from the eye. In Fig.1 schematically shows the proposed device, a general view} in Fig.2 - a section aa in Fig.1, fig.Z - lifting device in the initial position, the general view in Fig.4 - the same, when slinging for fig.Z - the same, in the working position; Figures 6 and 7 - the same, when the cargo is unravelable. The load gripping device comprises a housing 1 with a slit 2 and a hook 3 located in the lower part of the housing 1, a latch L for engaging with a rigid eye 5 of the load mounted on an axis 6 positioned on the toe of the hook 3, and representing a three-shouldered lever, a flat rod 922 the 7, placed in the upper part of the cheeks of the body 1 above the toes of the hook 3. In addition, the three-shouldered lever is spring-loaded through the spring 8 and has the ability of the Shoulder 9 to interact with the flat spring 7, the eyelet 5 of the load and facing each other with the slot 2, and pl Lines 10 and 11 - with an eye 5 of the load. Load handling device operates as follows. The cargo eye 5 loads into the slot 2 of the cheeks of the body 1 of the load gripping device (Fig. 3 and 4), which is hung on the lifting mechanism (conventionally not shown). When moving the lifting device relative to the eye of the load up (lifting the load), the proppin 5 of the load, moving on the shoulder 9 of the latch 4, acts on it and occupies the lowest position (figure 5). In this case, the latch, turning around the axis, depresses the flat spring 7, overlapping part of the slot 2. After transporting the cargo and placing it on the bearing surface, the load gripping device moves down relative to the rigid lug of the cargo (Fig. 6), until it stops. the way the shoulder 9 of the latch 4. The spring 8 returns the latch 4 to the position shown in Fig.6. Further, when lifting the load gripping device, the cargo eye, moving along the shoulder 9 of the latch 4, comes out of the slot 2 of the load gripping device, affecting the latch 4 on the shoulder 11, turning it to its original position (Fig. 3). The restrictive flat spring 7 must have resistance preventing the clamp 9 from moving from one extreme position (fig. 3) to the other (fig. 3) when stitching and unraveling the load and at the same time its force must have less force on the shoulder 9 when it is rotation around the axis under the influence of the weight of the load acting on the shoulders 10 and 11. This invention provides a more secure fixation of the load on the lifting mechanism, reduces the load slinging time and allows you to automate the slinging process.
