Abstract

The invention relates to a mine lifting hook device. The mine lifting hook device comprises a lifting hook (10), a rotary lifting ring (7), a rotary shaft clamp (5), a bidirectional connector (3) and a conical sleeve (1), wherein a security clamp (11) is arranged on one side of the lifting hook (10); a clamping ring (8) is connected with the top end of the lifting hook (10); a stepped hole (13) is formed at one end of the rotary lifting ring (7); a bearing (6) is arranged inside the stepped hole (13); the other end of the rotary lifting ring (7) is connected and matched with the clamping ring (8); a screw (14) is arranged at one end of the rotary shaft clamp (5), where a stepped shaft of the rotary shaft clamp (5) is connected and matched with the bearing (6); the screw (14) connected and matched with a nut (15); the nut (15) is connected and matched with the bearing (6); a U-shaped connecting base is arranged at the other end of the rotary shaft clamp (5); one end of the bidirectional connector (3) is hinged with a U-shaped connecting base of the rotary shaft clamp (5) through a pin shaft; the other end of the bidirectional connector (3) is hinged with one end of the conical sleeve (1); and a conical part is arranged at the other end of the conical sleeve (1) and is connected with a steel wire rope. Due to the technical scheme, the mine lifting hook device can lift large mine equipment and has the characteristics of simple structure, convenience for manufacturing, large lifting tonnage and the like.

Description

A kind of mining cargo hook gear

Technical field

The present invention relates to a kind of lifting appliance, particularly a kind of mining cargo hook gear.

Background technology

Along with China market economy, the development of science and technology, improving constantly of well construction technology and construction mechanization level, the average depth of China's shaft building and cross section diameter are also constantly being deepened, are being strengthened, the mine cargo hook gear of former usefulness closely can't satisfy now larger mine lifting main equipment demand.

Summary of the invention

Purpose of the present invention is exactly that existing lifting appliance can't lift by crane defective large-scale, heavy wares in the prior art in order to solve, and a kind of mining cargo hook gear is provided.

The present invention seeks to be achieved by the following technical programs:

A kind of mining cargo hook gear comprises suspension hook, and a side is provided with insurance card on the suspension hook, and the suspension hook top is connected with snap ring, characterized by further comprising:

A. rotating hoisting ring, rotating hoisting ring one end is provided with stepped hole, is provided with bearing in the stepped hole, and the rotating hoisting ring other end is connected cooperation with snap ring;

B. S. A. card, its stepped shaft are connected with bearing and cooperate an end to be provided with screw rod, and screw rod is connected cooperation with nut, and nut is connected cooperation with bearing, and the other end is provided with the U-shaped Connection Block;

C. bidirectional joint, the one end is hinged by bearing pin and S. A. card U-shaped Connection Block;

D. conical bush, an end of the other end of bidirectional joint and conical bush is hinged, and the conical bush other end is provided with tapering part and is connected with steel rope.

On the basis of above technical scheme, following further technical scheme can be arranged:

The U-shaped Connection Block of described S. A. card is hinged by an end of No. two bearing pins and bidirectional joint.

One end of described conical bush is u shaped connector, and is hinged by an end of a bearing pin bidirectional joint.

Owing to adopted technique scheme, so that the present invention can realize the mine main equipment is lifted, and has simple in structure, easy to make, the large high of lifting tonnage.

For more detailed explanation the present invention, following accompanying drawing provides a most preferred embodiment.

Description of drawings:

Fig. 1 is structural representation of the present invention.

As shown in Figure 1, a kind of mining cargo hook gear provided by the invention, comprise suspension hook 10, a side is provided with insurance card 11 on the suspension hook 10, suspension hook 10 tops are connected with snap ring 8 by No. three bearing pins 9, be connected with rotating hoisting ring 7 on the snap ring 8, rotating hoisting ring 7 one ends are provided with stepped hole 13, bearing 6 is installed in the stepped hole 13, bearing 6 and S. A. card 5 are connected cooperation with an end of stepped shaft, stepped shaft one end of S. A. card 5 is provided with screw rod 14, and screw rod 14 is connected cooperation with nut 15, and nut 15 is connected cooperation with bearing 6, S. A. card 5 other ends are provided with U-shaped Connection Block, U-shaped Connection Block and bidirectional joint 3 to pass through No. two bearing pins 4 hinged, the other end of bidirectional joint 3 is hinged with conical bush 1U type end by a bearing pin 2, the other end connecting steel wire ropes of conical bush 1.

Present embodiment has following two kinds of models, and is as shown in the table:

Design parameters:

Principle of work: when the lifting well-bucket, the small end of steel rope from conical bush inserted, then fixing, in that the lifting article are hung over above the suspension hook, then block with insurance card, weight just can not break off relations like this, when descending, steel rope can produce rotational force, owing at rotating hoisting ring bearing is housed, under the rotation of bearing, just can unload rotational force and remove, avoided because the potential safety hazard that the weight rotation brings.
