Description

The molten steel jar is with turning over a jar hook

Technical field

The utility model relates to the molten steel hanging apparatus, especially belongs to the turn over jar hook of molten steel jar with lifting.

Background technology

At present, in the lifting of molten steel jar and during the hanging pot before turning over jar, because the diameter (Φ 900mm) of suspension hook group middle pulley group is greater than gib head diameter (Φ 540mm), the lifting hook pulley cover knocks tank body down earlier and causes the hanging pot difficulty, even can't hanging pot, thus influence production.As continuous casting 280t hoisting crane, finish the molten steel jar turned over and jar residual steel be poured out recovery, need to utilize secondary volume 75t suspension hook to tangle pot bottom and turn over the tank arrangement gudgeon.Need 2 people to finish jointly during the operation of reality hook, 1 refers to hang the worker with commanding crane, the auxiliary hook of other 1 workman, driver operation crane simultaneously.The necessary good teamwork of both sides has deviation just can't hang up gudgeon slightly; Usually needed just can hang up properly in 3～5 minutes.The problem of depositing in its operating process:

1. crane operator needs the two-way pair volume that starts to make the suspension hook swing, can finish the hanging pot operation.While suspension hook cover can clash into the molten steel tank and cause gib head pulley cover to be damaged, to be out of shape, and also can cause steel rope to squeeze off when serious and scrap, and safety misadventure takes place.

2. because after the diameter of suspension hook group middle pulley group greater than the size in the same way of suspension hook, hung hook, pair twisted in to hoist and turns in jar process, steel rope and molten steel jar jar be along friction, severe wear steel rope, reduction service life.

3. when the hanging pot operation, need 2 people common the cooperation to finish and need just can hang up properly in 3～5 minutes, labour intensity is big, and influences production time.

4. often have in the production process slag spill tank body, jar along or gudgeon on, form accumulated slag or the gudgeon weldering lived, strengthened the difficulty of operation.

Standard is forged when being hooked in the hanging pot operation and is had the following disadvantages:

1. standard is forged hook and is used the long handle screw rod with the assembly pulley disc. and nut is connected, and forges hook and can freely rotate hanging pot operation location difficulty.

2. standard is forged hook gib head physical dimension less than pulley cover diameter, hanging pot operation steel cable. pulley cover and big tank body. and a jar edge rubs, and has potential safety hazard.

3. standard is forged hook because of complex structure, and examination and maintenance are difficult for.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of hook convenient, accurate, and the hook time is short, and labour intensity is low, and the molten steel jar that be improved the service life of suspension hook and steel rope is with turning over a jar hook.

Realize the technical measures of above-mentioned purpose:

The molten steel jar mainly is made up of gib head, the neck of hook with turning over a jar hook, it is characterized in that: gib head is the anchor shape; Adopting angle to be 110～140 ° between anchor hook head and the neck of hook is connected; Neck of hook lower end is connected with balance block, is connected with strut bar between anchor hook head and balance block; Forming sky between anchor hook head, balance block and strut bar three engraves; Be provided with pin shaft hole in neck of hook upper end.

It is characterized in that: be provided with the counterweight hole on balance block, clump weight is placed in the counterweight hole.

The utility model not only makes hook convenient, accurately, shortens hook time to 1～2 minute, has also improved operator's labour intensity, has guaranteed personal safety, has improved the service life of suspension hook and steel rope, and is simple in structure, firm firm.

Description of drawings

Fig. 1 uses the structural representation that turns over jar hook for the molten steel jar

The specific embodiment

Be described further below in conjunction with accompanying drawing:

The molten steel jar is made up of gib head 1, the neck of hook 2 with turning over a jar hook.Gib head 1 is processed as the anchor shape; Angle between the anchor hook head 1 and the neck of hook 2 is 110 °/120 °/135 °/140 °, and adopts riveted joint or whole machine-shaping to connect as one; The neck of hook 2 lower ends adopt riveted joint or whole machine-shaping to connect balance block 3, the neck of hook 2 upper end disease tooling pin axis holes 4; Between anchor hook head 1 and balance block 3, adopt welding or riveted joint strut bar 5; Between anchor hook head 1, balance block 3 and strut bar 5 threes, form sky and engrave 6.

For convenience of the balance adjustment between balance block 3 and anchor hook head 1, so be processed with counterweight hole 7 on balance block 3, the serial clump weight 8 of making is placed on when needed in the counterweight hole 7 and gets final product.

In use, owing to pin shaft hole 4 in, adopt Xiao Zhou to be connected between the neck of hook 2 and the assembly pulley, make the arm of force of anchor hook head 1 short and be fixed type, so anchor hook head 1 is rotated or swing, so the one-time-reach-place accuracy rate significantly improves when the hook operation, the time spent shortens.

Claims (2)

1. the molten steel jar mainly is made up of gib head, the neck of hook with turning over a jar hook, it is characterized in that: gib head is the anchor shape; Adopting angle to be 110～140 ° between anchor hook head and the neck of hook is connected; Neck of hook lower end is connected with balance block, is connected with strut bar between anchor hook head and balance block; Forming sky between anchor hook head, balance block and strut bar three engraves; Be provided with pin shaft hole in neck of hook upper end.

2. molten steel jar as claimed in claim 1 is characterized in that with turning over a jar hook: be provided with the counterweight hole on balance block, clump weight is placed in the counterweight hole.
