The repair maintenance of later period resistance to material.
Molten steel in steel ladle during 4. the upper surface of outer cover of the present invention has assigned thermometer that handling can be monitored in real time
Surface temperature situation of change is conducive to the control of production technology.
5. coupler body lower arm of the present invention upper end is symmetrically mounted on the two sides of crossbeam by pin shaft, make lower arm and hook head portions can be with
It swings along pin shaft, is conducive to the extension unhook operating efficiency for promoting steel ladle.
6. the present invention be provided with chain between cover and coupler body crossbeam, can falling to avoid the small cover of abnormal conditions, really
Protect equipment safety.
7. the sub- hook that the lower end of coupler body crossbeam of the present invention is arranged is designed using W type double hook nest, match with shutter horizontal swinging arm
The stability of cover during handling can be guaranteed to avoid the shaking of cover by closing.

Specific embodiment
With reference to embodiment, the present invention is furture elucidated, it should be understood that following specific embodiments are only used for
It is bright the present invention rather than limit the scope of the invention.
As shown in Figure 1, the present embodiment steel ladle keep the temperature handling suspender, including coupler body 1, cover 3 and with the cover
The shutter 2 being fixedly connected is provided with the sub- hook 15 for shutter described in handling, the shutter packet on the coupler body
The pedestal 21 connecting with the cover is included, two sides are provided with axle sleeve on the pedestal, and each axle sleeve passes through axis one
23 are connected with swing arm 22, are respectively welded on the inside of each swing arm and close block 26 and rocker arm 27, two are opened the one of link stopper 24
Side is mounted in the axle sleeve among pedestal by an axis 2 25, and each opening the other side of link stopper, to pass through axis 3 28 respectively right with it
The rocker arm connection answered, is provided with locking spring 29 between the rocker arm upper end and the pedestal.
The steel ladle keeps the temperature handling suspender, and the coupler body includes crossbeam 12, the both ends point on the crossbeam top
It is not provided with pulley blocks 11, two side lower part of crossbeam connects lower arm 13, each lower arm connection by pin shaft respectively
One gib head 14, the crossbeam lower part centre connection sub- hook 15, the crossbeam two sides connect chain by hangers
16。
The steel ladle keeps the temperature handling suspender, and the cover includes the outer cover 31 of hollow cylinder structure, described
It is uniformly distributed one group of keel 32 from axle center is radial inside outer cover, is welded at 1/2 radius of keel circumference cyclic annular solid
Fixed rack, nesting is equipped with pyroceram fibre material 33 between the outer cover and the keel.
The steel ladle keeps the temperature handling suspender, and the cover top is provided with thermometer 34.
The course of work:
Prepare before lifting: before steel ladle lifting operation, hoister first passes through sub- hook 15 and hooks the promotion of cover 3, that is, is opened and closed
Device 2 is in closed state, and 22 upper end of swing arm of shutter 2 is located in the two sides hook nest of sub- hook 15 this moment.
Steel ladle lifting: after receiving lifting instruction, coupler body 1 is placed in the dead astern position of steel ladle by hoister,
Gib head 14 is simultaneously declined to bill tip height lower than (i.e. H1=10cm) at steel ladle trunnion bottom 10cm, then operates coupler body 1
The hook position that gib head 14 reaches steel ladle is moved forward to, then low speed decline coupler body falls in the packet edge of steel ladle by cover
On, while continuing to decline that 14 ends under coupler body 1 to sub- hook touch shutter opens block 24, the swing arm 22 on shutter 2 this moment
In the case where opening block and rocker arm effect, Unscrew, 22 upper end of swing arm this moment are left sub- 15 hook nest of hook, are risen again outward respectively
Steel ladle is simultaneously sling transport to requiring position by gib head by coupler body 1.
Steel ladle falls packet: first controlling when steel ladle reaches the position for needing to fall after driver receipt to steel ladle falls packet instruction
Coupler body 1 processed drops to steel ladle landing and bill tip height lower than (i.e. H1=15cm) at steel ladle trunnion bottom 15cm, then
Low speed decline coupler body 1 allows to sub- 15 lower end of hook the block that closes for touching shutter, and block is being closed in the swing arm 22 on shutter this moment
Under the action of 26, side rotation is closed up respectively inwards for the upper end, is put this moment, 22 upper ends enter in sub- hook hook nest, rise coupler body 1 again
To bill tip height lower than at steel ladle trunnion bottom 10cm (i.e. H1=15cm), this triplet hook passes through shutter for cover
Slinging separates it with steel ladle packet edge.It is mobile to steel ladle dead astern until gib head leaves steel completely that driver operates coupler body 1 again
Water packet hangers region, operating again coupler body 1 rising to proper height position is that steel ladle lifting next time is got ready.
