The screw 31 is sleeved with an adjusting washer 311, and the adjusting washer 311 is located between the fixing plate 21 and the side wall of the slot 221 near one end of the sling 1. The adjusting washer 311 is used to reduce the gap between the fixing plate 21 and the side wall of the slot 221, so that the clamping effect of the adjusting seat 22 and the top wall of the i-steel is better. The number of the adjusting pads 311 is reasonably selected according to the gap between the fixing plate 21 and the slot 221, the adjusting pads 311 are usually set to be thin, and two ends of the adjusting pads 311 are smooth and flat, so that when a plurality of adjusting pads 311 are stacked, the adjusting pads 311 and the adjusting pads 311 are tightly attached.

One end of the fixed plate 21 close to the sling 1 is provided with a connecting plate 4. The middle of the connecting plate 4 is rectangular, and the two ends of the connecting plate 4 are semicircular. Two ends of the connecting plate 4 are respectively fixed on the two adjusting seats 22, and the connecting plate 4 is connected with the adjusting seats 22 through connecting bolts 41. The connecting plate 4 further strengthens the connecting effect between the two adjusting seats 22, and the two adjusting seats 22 are not easy to skew at the two ends of the fixing plate 21, so that the overall structural stability of the clamping seat 2 is better.

The adjusting seat 22 is provided with a plurality of threaded counter bores 223 for the connecting bolts 41 to be screwed in at equal intervals along the sliding direction of the adjusting seat 22, and correspondingly, the connecting plate 4 is provided with a plurality of through holes 42 for the connecting bolts 41 to pass through along the sliding direction of the adjusting seat 22. When the width of the top wall of the I-shaped steel changes, the distance between the two adjusting seats 22 changes, and the connecting bolt 41 when the connecting plate 4 is fixedly connected with the adjusting seats 22 is correspondingly positioned in the through hole 42 and the threaded counter bore 223 at different positions.

The top of adjusting seat 22 and keeping away from fixed plate 21 one end is equipped with lug 224, and welded fastening between lug 224 and the fixed plate 21, the equal symmetry setting of lug 224 of two regulation seats 22. The cover is equipped with the journal stirrup 5 on hoist cable 1, and the journal stirrup 5 slides with hoist cable 1 and is connected, and fixes through spacing subassembly 6 between journal stirrup 5 and hoist cable 1. A hanging chain 7 is arranged between the lifting lug 224 and the shaft lug 5, and two ends of the hanging chain 7 are respectively arranged on the lifting lug 224 and the shaft lug 5 in a penetrating way.

When fixing holder 2, loosen spacing subassembly 6 of journal stirrup 5, and make journal stirrup 5 slide along the direction that is close to fixed plate 21 on hoist cable 1, so that adjust seat 22 and can smoothly slide on fixed plate 21, then through adjusting the roof centre gripping of seat 22 with the I-steel, and will adjust seat 22 and fix on fixed plate 21, then make journal stirrup 5 slide along the square of keeping away from fixed plate 21 on hoist cable 1, until hanging chain 7 accomplishes the straightness that stretches out, then fix journal stirrup 5 on hoist cable 1 through spacing subassembly 6. The hanging chain 7 is used for connecting the adjusting seat 22 with the sling 1 so as to enhance the shaking prevention performance of the I-steel with a steel structure during hoisting, and thus the hoisting process is more stable and safer.

Referring to fig. 1 and 3, the journal stirrup 5 includes a socket portion 51 and a ring portion 52. The sleeving part 51 is in a circular tube shape, the sleeving part 51 is used for sleeving the axle lug 5 on the sling 1, the circular ring part 52 is welded and fixed on the outer side wall of the sleeving part 51, the circular ring part 52 corresponds to the hanging chain 7 one by one, and the circular ring part 52 is used for connecting and fixing the hanging chain 7. The stop assembly 6 comprises an abutment block 61 and an abutment bolt 62. The abutting block 61 is located between the inner side wall of the sleeving part 51 and the sling 1, the section of the abutting block 61 is arc-shaped, and the abutting bolt 62 penetrates through the sleeving part 51 along the circumferential direction of the sleeving part 51.
