Specific embodiment
As shown in Figs. 1-5, the direction a kind of lifting lug P tension grip, including first sleeve 2, in 2 inside of first sleeve
Sky is fixed with the first vertical column 1 at the top of first sleeve 2, external screw thread is equipped on the first column 1, in first sleeve 2
It is equipped with symmetrical through-hole, horizontally disposed lateral pin 3 is equipped in through-hole, the hanging ring 41 of lifting lug 4 to be tested is arranged in first set
In cylinder 2 and be hooked on lateral pin 3, lifting lug to be tested 4 and 2 clearance fit of first sleeve, the longitudinal centre line of lifting lug 4 to be tested with
The longitudinal centre line of first column 1 is overlapped.
It is equipped with second sleeve 5 in the lower section of first sleeve 2, the opening of the two is opposite, and interior spiral shell is equipped in second sleeve 5
The interconnecting piece 40 of line, lifting lug 4 to be tested is arranged in second sleeve 5 and is threadedly engaged with second sleeve 5, in second sleeve 5
Bottom is fixed with the second vertical column 6, is equipped with external screw thread on the second column 6, the longitudinal centre line of the second column 6 be overlapped with
The longitudinal centre line of first column 1 is overlapped.
Second column 6 is identical as the outer diameter of the first column 1, and the experimental rig 7 for using lifting lug both ends is identical, reduces tooling
Type, it is easy to process.
Locating slot is equipped on lateral pin 3, the hanging ring 41 of lifting lug 4 to be tested is arranged in locating slot, facilitates lifting lug 4 to be tested
