Abstract

The utility model discloses a spreader for single-arm cranes. The structure of the spreader is as follows: the spreader is composed of a connecting seat, two upper connecting rods, two lower connecting rods and two spreader claws, wherein the upper ends of the upper connecting rods are hinged with the lower part of the connecting seat, and the hinged parts of the two connecting rods are coaxial; the lower ends of the two upper connecting rods are respectively hinged with a lower connecting rod; the middle parts of the two lower connecting rods are mutually hinged; and the two spreader claws are respectively arranged at the lower ends of the two lower connecting rods. The spreader disclosed by the utility model has the beneficial effects that: the spreader claws of the spreader disclosed by the utility model can adapt to the appearances of differential mechanism assemblies, so that the spreader claws can carry out hoisting operation on the differential mechanism assemblies, thereby reducing the labor intensity of operators.

Description

The single armed sling

Technical field

The utility model relates to a kind of lifting appliance, relates in particular to a kind of single armed sling.

Background technology

In the prior art; When adopting horizontal Machining centers (KNH-400) processing diff component brill dish hole, need operator's a dead lift product spare and adjusting device, labour intensity is very big: every heavily about 0.035 ton of diff component; Heavily about 0.005 ton of anchor clamps pressing plate; Calculate to process 130 products every day, the operator approximately need take 10.4 tons weight every day in one's arms, and high-intensity like this carrying amount makes laborer suffer from lumbar muscle strain easily.

The utility model content

To the problem in the background technology, the utility model provides a kind of single armed sling, its structure is: it is made up of Connection Block, two boxed rods, two lower links and two suspender pawls; The upper end of boxed rod and Connection Block lower hinge, and the hinged place of two boxed rods is coaxial; The lower end of two boxed rods each with rod hinge connection once; Two lower link middle parts are mutually hinged; Two suspender pawls are separately positioned on the lower end of two lower links.

Being shaped as of said suspender pawl: the suspender pawl is provided with semicircle breach; Semicircle gap position on two suspender pawls is relative.

The Connection Block upper end is provided with suspension ring, and suspension ring are connected with lifting appliance.

The useful technique effect of the utility model is: the suspender pawl of the utility model can adapt to the profile of diff component it is carried out lifting operation, reduces operator's labour intensity.

The specific embodiment

A kind of single armed sling, its structure is: it is made up of Connection Block 1, two boxed rods 2, two lower links 3 and two suspender pawls 4; The upper end of boxed rod 2 and Connection Block 1 lower hinge, and the hinged place of two boxed rods 2 is coaxial; Each is hinged with a lower link 3 in the lower end of two boxed rods 2; Two lower link 3 middle parts are mutually hinged; Two suspender pawls 4 are separately positioned on the lower end of two lower links 3.The principle of work of the utility model is: with the high spot of two suspender pawl 4 blocks on diff component shell; When lifting appliance is upwards sling Connection Block 1; Because the constraint effect of hinged place, two lower link 3 middle parts, two suspender pawls 4 are clamped the diff component as a pair of tongs and are upwards mentioned; When needs put down the diff component, only need the diff component is put down, suspender pawl 4 has just unclamped automatically, and this is simple and practical, can solve well to add the artificial frequent problem of part up and down of needs in man-hour, has reduced working strength of workers.

In order to make suspender pawl 4 can catch the diff component more reposefully, shape that can suspender pawl 4 is set to: suspender pawl 4 is provided with semicircle breach; Semicircle gap position on two suspender pawls 4 is relative.Connection Block 1 upper end is provided with suspension ring 5, and suspension ring 5 are connected with lifting appliance.
