According to the technical scheme, the mining lifting hook device can lift mine large-scale equipment, and has the characteristics of simple structure, convenience in manufacture, high lifting tonnage and the like.

Description

A kind of mining cargo hook gear

Technical field

The utility model relates to a kind of lifting appliance, particularly a kind of mining cargo hook gear.

Background technology

Along with China market economy, science and technology development, 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 big mine lifting main equipment now demand.

The utility model content

The purpose of this utility model 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 utility model purpose is 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, it is characterized in that also comprising:

A. rotation suspension ring rotate suspension ring one end and are provided with stepped hole, are provided with bearing in the stepped hole, and the rotation suspension 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. two-way 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 two-way 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 two-way joint.

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

Owing to adopted technique scheme, make the utility model can realize the mine main equipment is lifted, and have characteristics such as simple in structure, easy to make, the big height of lifting tonnage.

For more detailed explanation the utility model, following accompanying drawing provides a most preferred embodiment.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

The specific embodiment:

As shown in Figure 1, a kind of mining cargo hook gear that the utility model provides, 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 rotation suspension ring 7 on the snap ring 8, rotation suspension ring 7 one ends are provided with stepped hole 13, bearing 6 is installed in the stepped hole 13, bearing 6 is connected cooperation with the end that S. A. card 5 has 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 two-way joint 3 to pass through No. two bearing pins 4 hinged, the other end of two-way joint 3 is hinged with conical bush 1U type end by a bearing pin 2, the other end of conical bush 1 connects steel rope.

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

Design parameters:

Figure DEST_PATH_715934DEST_PATH_IMAGE001

Principle of work: when the lifting well-bucket, the small end of steel rope from conical bush inserted, fixing then, in that the lifting article are hung over above the suspension hook, block with insurance card then, weight just can not break off relations like this, when descending, steel rope can produce rotational force, owing at the rotation suspension 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.
