As shown in figure 1, the utility model relates to a pipeline hoist and mount specialized tool, including hoist body 2 and the tight assembly of clamp.

In embodiment 1, the top of the hanger body 2 is provided with a hanging ring 1. The lifting appliance is characterized in that supporting rods 6 are arranged at two ends of the bottom of the lifting appliance body 2, and the inner sides of the supporting rods 6 are connected with a cross rod 11.

The clamping assembly comprises a hydraulic telescopic rod 3, a first connecting rod 4, a second connecting rod 5, a third connecting rod 7, a fourth connecting rod 8, a T-shaped suspender 9 and an arc-shaped clamping plate 10.

The top end of the hydraulic telescopic rod 3 is connected with the center of the bottom of the lifting appliance body 2, and the bottom end of the hydraulic telescopic rod is connected with the middle section of the first connecting rod 4. The two ends of the first connecting rod 4 are hinged with second connecting rods 5, the outer ends of the second connecting rods 5 are hinged with third connecting rods 7, the third connecting rods 7 are hinged with the middle sections of transverse rods 11 of the supporting rods 6, the inner ends of the transverse rods 11 are hinged with fourth connecting rods 8, the bottoms of the third connecting rods 7 and the fourth connecting rods 8 are hinged with the two ends of the top of a T-shaped suspender 9 respectively, and the inner sections of the transverse rods 11, the lower sections of the third connecting rods 7, the fourth connecting rods 8 and the T-shaped suspender 9 are hinged to form a parallel four-bar mechanism.
