Described ring goes out the machine suspender, it is characterized in that: the angle between adjacent struts is identical.

Described ring goes out the machine suspender, it is characterized in that: be respectively equipped with row's pin-and-hole on each strut, described curve of cranking arm is provided with through hole, and the pin of a pin-and-hole on described crank arm through hole by passing successively the curve of cranking arm and strut in row's pin-and-hole is hinged on strut.

Described ring goes out the machine suspender, it is characterized in that: described cranking arm includes bending bar and the vertical bar that one connects, and wherein the length of bending bar is greater than the length of vertical bar.

Beneficial effect of the present invention:

The present invention is the three-jaw Automatic hook block, only need the one man operation overhead traveling crane can complete the discharging operation of ring, need not many personnel's cooperations and can realize that rolling ring hangs out milling train safely and fast, and ring can not produce distortion in whole discharging process, and after the ring discharging, stacking is convenient, adapts to especially the loose of ring normalizing process and puts.

Description of drawings

Fig. 1 is structural representation of the present invention, and state as shown in the figure is the state of the present invention when lifting by crane.

The specific embodiment

referring to Fig. 1, a kind of ring goes out the machine suspender, include strut socket 1, surrounding around strut socket 1 has respectively three outward extending struts 2, wherein the angle between adjacent struts is identical, be 120 °, be hinged with respectively on three struts 2 and crank arm 3, crank arm 3 bottom has top 4, be fixedly connected with vertical guide rod 5 on strut socket 1, stop collar 16 is installed on guide rod 5 from bottom to top successively, slip ring 6 and taper sheath 7, wherein slip ring 6 can slide up and down along guide rod 5, stop collar 16 and taper sheath 7 are fixedly mounted on guide rod 5, the upper end of slip ring 6 outer walls is provided with the conical surface, the lower end of slip ring 6 outer walls is provided with inverted cone surface, the lower end of taper sheath 7 is provided with the taper hole 8 that the conical surface with slip ring 6 outer wall upper ends is complementary, include conduit 9, conduit 9 slides up and down along the upper end of guide rod 5, the bottom of conduit 9 is installed with hook seat 10, surrounding around hook seat 10 has respectively three suspension hooks 11, the bill section of three suspension hooks 11 is hooked on the inverted cone surface of slip ring 6 outer wall lower ends, the end of conduit 9 is installed with suspension ring 12, has respectively on 13, three bearings 13 of three bearings and three struts 2 around the surrounding of conduit 9 upper ends to be connected with respectively steel rope 14 between hinged 3 the upper end of cranking arm.

In the present invention, be respectively equipped with row's pin-and-hole 15 on each strut, 3 the curve of cranking arm is provided with through hole, crank arm 3 by passing successively 3 curves of cranking arm through hole and strut on the pin of a pin-and-hole in row's pin-and-hole 15 be hinged on strut.

In addition, cranking arm 3 includes bending bar that one connects and vertical bar, and wherein the length of bending bar is greater than the vertical length of bar.

the present invention is suspended on lifting appliance by suspension ring 12, by overhead traveling crane hand-manipulated, make lifting appliance move down, the present invention moves to the top of milling train with lifting appliance, conduit 9 moves down along guide rod 5, hook seat 10 also moves down with conduit 9 at this moment, slip ring 6 is positioned on stop collar 16, three suspension hooks 11 open and are displaced downwardly to the below of slip ring 6 gradually along the outer wall of taper sheath 7, this moment, steel rope 14 was in relaxed state, 3 the bending bar of cranking arm outwards opens, 3 the vertical bar of cranking arm inwardly shrinks, along with lifting appliance continue move down, 3 the vertical bar of cranking arm extend in ring on milling train.

the manual operations overhead traveling crane, make lifting appliance move up, this moment, conduit 9 moved up along guide rod 5, hook seat 10 also moves up with conduit 9, three suspension hooks 11 shrink, on move and hook slip ring 6 the lower end, driving slip ring 6 moves up, until the upper end conical surface of slip ring 6 enters in the taper hole 8 of taper sheath 7 lower ends fully, because taper sheath 7 maintains static, this moment, conduit 9 stopped moving up, steel rope 14 tightens up, 3 the bending bar of cranking arm inwardly shrinks, 3 the vertical bar of cranking arm outwards opens and finally is in vertical state, the crank arm top 4 of 3 bottoms is stuck in the bottom side edge edge of ring, crank arm and 3 fully ring is clamped, and the ring of slinging under lifting appliance promotes.

With above-mentioned step, the present invention can complete entrucking, the stacking operation of ring, and is very convenient.
