Description

A kind of cargo hook gear

Technical field

The utility model relates to a kind of cargo hook gear, belongs to mechanical field.

Background technology

Lifting job is widely used in metallurgical iron-making and steel-making industry field, during the maintenance of big machinery engineering industry and equipment is installed, in identical operation, uses necessary suspender to can greatly improve operating efficiency, reduce the risk.

Shanxi Taiyuan Iron and Steel Co. hot continuous rolling factory mm finishing mill unit at every turn when changing the F0-6 anvil roll, at first must traversing large floor and little floor totally 14 hang away, heavily approximately 10 tons on large floor, anvil roll is changed one time on heavily approximately 2.5 tons on little floor, lifts floor operation at least 28 times.Former finish rolling size floor erecting by overhang is made of steel plate, is slab construction, and in the lifting job, first suspension hook being put into behind the hole for hoist of floor must be artificially with the suspension hook half-twist, can carry out lifting operation after making suspension hook block the floor.Because four pore size distributions are far away, want at least four hands of two humans to catch respectively steel rope to prevent that suspension hook from rotating and break off relations, the 3rd people commands the crane vertical motion.After the lifting of floor, owing to hanging the external factor impacts such as thing is unstable, unbalance stress, suspension hook also easily rotates and breaks off relations, and hangs thing in a single day to drop, and easily causes personnel and equipment grave accident, dangerous high and inefficiency.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provides a kind of cargo hook gear, avoid suspension hook that the phenomenon that breaks off relations in the hole for hoist of floor occurs in the lifting process, improve operating efficiency, reduce operation intensity and difficulty, make that lifting job is simple, convenient operation, reduce or avoid the safety misadventure of personnel and equipment to occur.

The technical solution adopted in the utility model is: a kind of cargo hook gear, comprise suspension ring, main hook part, and it is characterized in that: also comprise joint pin, described main hook part is the hemisphere structure, and suspension ring are connected by joint pin with main hook part.

In the such scheme, the height of described main hook part is 60mm.

Former suspension hook is slab construction, during handling, suspension hook put into the floor hole for hoist after, can lift by crane after must manually it being rotated 90 °.The utility model is through improving, and bottom section changes the hemisphere form into, and the hemisphere diameter is Φ 74mm, highly is 60mm, this suspension hook is put into the floor hole for hoist after, suspension hook rotary oscillation how no matter, suspension hook can not come off from hole for hoist.Middle interconnecting piece divides and is processed into cylindrical structure, diameter of phi 30mm, and length is 150mm, the cylindrical structure convenient operation prevents suspension hook corner angle and floor hole for hoist generation jam phenomenon.Loop configuration is adopted on suspension hook top, and bore dia is Φ 35mm, uses with 6 minutes steel rope couplings.

The beneficial effects of the utility model: (1) uses this cargo hook gear, improves operating efficiency more than 50% under the identical operation condition; (2) can prevent from hanging thing and after lifting initial stage and lifting, the unhook situation occur, avoid floor drop generation personnel and device security accident; (3) this cargo hook gear can reduce operating personnel's quantity, is operated simultaneously by original three people and changes present one man operation into, has reduced cost of labor.

Below in conjunction with drawings and Examples the utility model is described further.

1 is that suspension ring, 2 are connecting panel among the figure, and 3 is main hook part, and 4 is suspension ring, and 5 is joint pin, and 6 is main hook part.

The specific embodiment

Embodiment:

Fig. 1,2 shows the schematic diagram of prior art suspension hook, comprises suspension ring 1, connecting panel 2, main hook part 3, and suspension ring 1 are connected by connecting panel 2 with main hook part 3.Main hook part is slab construction, after suspension hook is put into hole for hoist, need artificial rotate 90 ° on suspension hook after, can stressedly lift by crane, before not stressed, suspension hook can deflect and the phenomenon that breaks off relations, hazard level is higher.

Fig. 3,4 shows the schematic diagram of the utility model suspension hook, comprises suspension ring 4, main hook part 6, it is characterized in that: also comprise joint pin 5, described main hook part 6 is the hemisphere structure, and suspension ring 4 are connected by joint pin 5 with main hook part 6.This suspension hook bottom section changes hemisphere into, and the hemisphere diameter is Φ 74mm, highly is 60mm, this suspension hook is put into the floor hole for hoist after, suspension hook rotary oscillation how no matter, suspension hook can not come off from hole for hoist; The suspension hook middle interconnecting piece divides and is processed into cylindrical structure, diameter of phi 30mm, and length is 150mm, the cylindrical structure convenient operation prevents suspension hook corner angle and floor hole for hoist generation jam phenomenon; Loop configuration is adopted on suspension hook top, and bore dia is Φ 35mm, uses with 6 minutes steel rope couplings.

The concrete method for making of the utility model suspension hook is: (1) suspension hook adopts the integrated machine workpiece, not handy welding or be threaded, annular design is adopted at reeve position, suspension hook top, and thickness is 30mm, the reeve bore dia is designed to Φ 35mm, and outside diameter is Φ 90mm; (2) middle interconnecting piece divides and is processed into cylindrical structure, diameter of phi 30mm, and length is 150mm, the cylindrical structure convenient operation; (3) the suspension hook bottom section changes the hemisphere form into, and the hemisphere diameter is Φ 74mm, highly is 60mm, this suspension hook is put into the floor hole for hoist after, can prevent that the locking hook phenomenon occurs, avoid safety misadventure to occur; (4) all connecting portions adopt R5mm arc transition chamfer design, avoid producing in the handling stress and concentrate and the damage suspension hook.

Claims (2)

1. a cargo hook gear comprises suspension ring, main hook part, it is characterized in that: also comprise joint pin, described main hook part is the hemisphere structure, and suspension ring are connected by joint pin with main hook part.

2. cargo hook gear according to claim 1, it is characterized in that: the height of described main hook part is 60mm.
