Description

Improved structure of lifting hook component of hoisting block

[ technical field ] A method for producing a semiconductor device

The utility model relates to a lifting hook part of hoist crane improves structure belongs to hoist crane lifting hook part technical field.

[ background of the invention ]

As is well known, hoist products are particularly concerned with safety requirements. Referring to fig. 7 and 8, a hook part of a conventional hoist comprises a hook 1 ', a rope blocking plate 2', an elastic member (not shown in the drawings), and a connecting member 4 ', wherein the hook 1' is provided with a mounting hole (hidden from view) at a neck portion 11 ', one end of the rope blocking plate 2' and the elastic member are mounted on the hook 1 'through the connecting member 4' inserted in the mounting hole, and the other end of the rope blocking plate 2 'abuts against an inner wall of a head 12' of the hook 1 ', and is elastically movable toward a hook cavity 1 a' and then returns to and closes the hook cavity under a restoring force of the elastic member after moving, and the following technical disadvantages exist when the structure of the hook part is carefully analyzed:

because the outer contour of the hook head 12 ' is smooth, the other end of the cable blocking plate 2 ' can generate unfavorable sliding on the outer contour surface of the hook head 12 ', the cable blocking plate 2 ' sometimes cannot completely close the hook cavity, and because the common cable blocking plate 2 ' is usually of a thin-wall structure, when a hoist generates unfavorable shaking in the lifting process of a heavy object, a lifting point can collide with the cable blocking plate 2 ', the cable blocking plate 2 ' has the risk of breaking or falling off integrally, and the heavy object slides out of the hook 1 ' once being separated from the blocking effect of the cable blocking plate 2 ', so that safety accidents are caused.

[ Utility model ] content

The utility model aims at providing an improved structure of a lifting hook component of a hoisting block for overcoming the defects of the prior art.

Therefore, the utility model provides a following technical scheme:

the utility model provides a hoist crane's lifting hook part improves structure, this lifting hook part comprises lifting hook, card cable board, torsional spring and connecting piece, and the hook neck at the lifting hook is installed through the connecting piece to the one end of card cable board, and the torsional spring suit is on the connecting piece, and its improvement point is offered the breach at the other end of card cable board, the lifting hook be formed with in its gib head position with the location portion of breach looks adaptation, the other end of card cable board arrives through its breach joint on the location portion.

The torsion springs are parallel double torsion springs and comprise torsion spring bodies, long torsion arms and short torsion arms, the connecting pieces are bolts and nuts, the torsion spring bodies are sleeved with the bolts, the short torsion arms are connected with the hook neck in a clamping mode, and the long torsion arms are abutted to the inner wall of the clamping cable plate.

The utility model has the advantages of as follows and positive effect:

the other end of the cable clamping plate is provided with the notch, and the hook head of the lifting hook is provided with the positioning part matched with the notch, so that under the action of the restoring force of the torsion spring, the other end of the cable clamping plate can be reliably clamped and positioned on the positioning part through the notch, the cable clamping plate does not generate unfavorable sliding relative to the hook head any more, the cable clamping plate completely closes the hook cavity, the hanging point or the hanging point of a heavy object can be reliably positioned in the hook cavity and cannot slide away from the hook cavity, and safety accidents are avoided.

[ detailed description ] embodiments

Referring to fig. 1, 2, 3, 4, 5 and 6, an improved structure of a hook component of a hoist block comprises a hook 1, a rope clamping plate 2, a torsion spring 3 and a connecting piece 4, wherein one end of the rope clamping plate 2 is installed at a neck portion 11 of the hook 1 through the connecting piece 4, the torsion spring 3 is sleeved on the connecting piece 4, the improved structure is characterized in that a notch 20 is formed at the other end of the rope clamping plate 2, a positioning portion 120 matched with the notch 20 is formed at a hook head 12 of the hook 1, the other end of the rope clamping plate 2 is clamped on the positioning portion 120 through the notch 20, namely, under the action of restoring force of the torsion spring 3, the other end of the rope clamping plate 2 touches the hook head 12, and the notch 20 is just clamped into the positioning portion 120.

The specific processing of the positioning part 120 can be directly performed on the hook head structure of the existing hook, the two side walls of the hook head 12 are respectively cut into steps 120-1, the two steps are transited to form the positioning part 120, and the end edge of the other end of the rope clamping plate 2 is abutted against the steps.

The torsion spring 3 is a parallel double-torsion spring and consists of a torsion spring body 31, a short torsion arm 32 and a long torsion arm 33, the connecting piece 4 is a bolt and a nut, the torsion spring body is sleeved with the bolt, the short torsion arm is clamped and connected with the neck of the hook, and the long torsion arm is abutted against the inner wall of the clamping cable plate 2.
