Description

A kind of mousing-hook steel ladle cover

Technical field

This utility model relates to continuous casting installation for casting, particularly to a kind of mousing-hook steel ladle cover.

Background technology

Conticaster is a kind of machine that liquid molten steel directly waters into solid-state steel billet, and capital equipment has steel Bag, steel ladle rotary table, tundish, plug rod mechanism, crystallizer, bobbing machine, cooling twice equipment, draw Rectify the part compositions such as machine, dummy bar, cutting equipment, knockout mechanism, water-cooled live-roller.

Ladle is the equipment for containing molten steel, in casting cycle, in order to ensure the heat reducing molten steel Loss, needs to cover steel ladle cover on ladle, to carry out heat retaining operation.

Seeing Fig. 1, ladle 10 is placed on steel ladle rotary table 20, driving carry out hanging taking.And ladle Lid 30 hangs on cantilever crane 40 suspension hook 50 on steel ladle rotary table, cantilever crane complete the liter of steel ladle cover Fall and rotation.Cantilever crane is made up of rotary part and lifting piece two parts, and rotary part implements cantilever The spinfunction hung；Lifting piece is a hoist engine structure, it is achieved the lifting of suspension hook, namely to steel Clad is implemented to rise and hang to take.

Owing to completing the manipulation of the position of steel ladle cover at a distance, operator are more difficult accurately to be observed Suspension hook and the situation of steel ladle cover upper lift ring.If suspension hook declines too much, it is easy to unhook phenomenon occur, It is exactly to remove on suspension hook suspension ring from steel ladle cover.Now need manually to carry out linking up with operation, by suspension hook Again being suspended in suspension ring, this operation labor intensity is big, dangerous high.

Although there being Anti-hook releasing device on suspension hook, but Anti-hook releasing device mainly relies on spring to be answered Position, in high temperature environments, spring easily lost efficacy so that mousing-hook function lost efficacy.

Summary of the invention

The purpose of this utility model is to design a kind of mousing-hook steel ladle cover, solves conticaster steel ladle cover and holds The problem easily broken off relations, makes steel ladle cover and suspension hook be not readily separated.

For reaching above-mentioned purpose, the technical solution of the utility model is:

A kind of mousing-hook steel ladle cover, including steel ladle cover and suspension ring；It also includes Anti-hook releasing device, and this is prevented Tripping gear includes, fixed mount, is installed on steel ladle cover central authorities, including, gripper shoe, under its central authorities Portion offers a groove；Described suspension ring are embedded in this groove；Some fixed plates, are respectively perpendicular and are arranged at The gripper shoe two sides of gripper shoe groove both sides；The two fixed plate top correspondences being positioned at gripper shoe side set Installing hole；One bearing pin, is arranged in the installing hole on the two fixed plate tops being positioned at gripper shoe side, bearing pin One end is by nut locking；L-shaped turnover panel, its bending place sets a sleeve, and is sheathed on described bearing pin central authorities, Sleeve two ends set positioning sleeve；L-shaped turnover panel rotates around bearing pin, and, L-shaped turnover panel be positioned at suspension ring Lower section.

Preferably, the angle of described L-shaped turnover panel bending place is 60 °～120 °.

Further, described L-shaped turnover panel lateral surface sets L-shaped gusset.

Also, the both sides of described L-shaped turnover panel are individually fixed on described sleeve, and, this L-shaped turnover panel Both sides are at an angle.

When this utility model installs suspension hook, the hook of suspension hook is carried on the back between suspension ring and L-shaped turnover panel, L-shaped Turnover panel while being positioned at steel ladle cover suspension ring, after steel ladle cover covers ladle, if suspension hook continue decline, Suspension hook is positioned at by pushing down in the plate of suspension ring, makes L-shaped turnover panel rotate, and drives another plate to draw close to suspension hook, Push down suspension hook, make suspension hook outwards to remove, to realize mousing-hook function.

The beneficial effects of the utility model:

1. realize the mousing-hook function to suspension hook.

2. pair existing structure is changed little.

3. simple in construction, make, easy to maintenance, low cost.

Detailed description of the invention

Seeing Fig. 2～Fig. 7, a kind of mousing-hook steel ladle cover of the present utility model, including steel ladle cover 1 and hang Ring 2；It also includes Anti-hook releasing device 3, and this Anti-hook releasing device 3 includes that fixed mount 31 is installed on Central authorities on steel ladle cover 1, including, gripper shoe 31, its central lower offers a groove 311；Described hang Ring 2 is embedded in this groove 311；Some fixed plate 32,32 ' (as a example by gripper shoe 31 side, Lower same), it is respectively perpendicular gripper shoe 31 two sides being arranged at gripper shoe groove 311 both sides；It is positioned at Two fixed plate 32,32 ' top correspondences of gripper shoe 31 side set installing hole；One bearing pin 33, wears In the installing hole on two fixed plate 32, the 32 ' tops being positioned at gripper shoe 31 side, bearing pin 33 one end by Nut locking；L-shaped turnover panel 34, its bending place sets a sleeve 35, and is sheathed in described bearing pin 33 Centre, sleeve 35 two ends set positioning sleeve 36,36 '；L-shaped turnover panel 34 rotates around bearing pin 33, and, L Shape turnover panel 34 while being positioned at below suspension ring 2.

Preferably, the angle of described L-shaped turnover panel 34 bending place is 60 °～120 °.Described L-shaped is turned over Plate 34 lateral surface sets L-shaped gusset 37.

In the present embodiment, the both sides of described L-shaped turnover panel 34 are individually fixed on described sleeve 35, And, the both sides of this L-shaped turnover panel are at an angle.

During use, when suspension hook plays suspension ring, under the moment loading that the deadweight of L-shaped turnover panel produces, Making L-shaped turnover panel while rotating, pushing down suspension ring.After steel ladle cover pushes down ladle, if suspension hook continues to decline, Suspension hook will push down the L-shaped turnover panel push pedal on one side being positioned at suspension ring, make L-shaped turnover panel rotate, drive L-shaped Turnover panel another side compresses to suspension hook so that suspension hook will not outwards remove, thus realizes mousing-hook function.
