Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The utility model relates to a pin joint type central buckle suitable for a straddle type steel wire rope sling, which comprises two half bodies 5 which are oppositely closed left and right, wherein a cable clamp is formed by butt joint and clamps a main cable 1 through the pretightening force of a bolt; the two halves 5 have downwardly extending half-ears 6 at the bottom, and the central lanyard rod 4 is connected to the half-ears 6 by means of knuckle bearings 8.
The fixing parts of the top and bottom bulges of the half bodies 5 are provided with through holes, and the through holes of the fixing parts at two sides are opposite after the two combined half bodies 5 are butted and fixed through the pretightening force of the bolts 7.
The opposite surfaces of the left and right half bodies 5 are provided with a bulge and a groove which are matched with each other, and the half bodies 5 on the two sides are plugged with each other when being closed.
The lower part of the half ear plate 6 is provided with an ear plate hole, and the central buckling cable rod 4 is connected to the half ear plate 6 through a joint bearing 8. A single central lanyard post 4 is inserted between the side half-shells 6 to connect with the central lanyard clip, as shown in FIG. 2. The two central lanyard members 4 are each connected to a single half ear panel 6, as shown in fig. 3.
