Description

Change the special hanger of crystallizer copper pipe

Technical field

This utility model belongs to the lifting device of crystallizer copper pipe of continuous casting machine replacing, particularly a kind of to change crystallizer copper pipe Special hanger.

Background technology

Crystallizer copper pipe of continuous casting machine needs after a certain period of use time to crystallizer maintenance section to be keeped in repair, and works as crystallizer copper When tube lifetime expires or crystallizer copper pipe occurs abnormal, crystallizer maintenance section is changed to crystallizer copper pipe, meets production Demand.

Spray mold copper pipe is fixed mainly by two pieces of crystallizer copper pipe clamps suitable for reading in crystallizer, is changing crystallization Passed through crystallizer copper pipe clamp inside crystallizer with two steel wire ropes during copper pipe（Clamp blocks copper pipe together）Sling.

1st, when crystallizer copper pipe replacing is carried out, need with two steel wire ropes from crystallizer body interior（Crystallizer copper pipe Between outer wall and crystallizer inwardly projecting orifice）Pass through, copper pipe clamp is tied, clamp and copper pipe（Clamp blocks copper pipe）Hang out together. Due in small distance between crystallizer inwardly projecting orifice and crystallizer copper pipe outer wall, steel wire rope pierces into, it is more difficult to pass.

2nd, during with two steel wire ropes copper pipe is hung out, easily there is slip phenomenon in steel wire rope, during hanging out There is potential safety hazard.

Utility model content

The purpose of this utility model is to provide a kind of special hanger for changing crystallizer copper pipe, and its is rational in infrastructure, operation Simply, it is possible to reduce replacing construction, the labor intensity of worker is reduced, crystallizer copper pipe can be eliminated and hung out the safety that slippage is fallen Hidden danger.

What the purpose of this utility model was realized in：A kind of special hanger for changing crystallizer copper pipe, including affixed The crystallizer copper pipe of clamp coordinates and is arranged on crystallizer inside the shell, and the structure of special hanger is to be located in the U-shaped khaki of horizontal Screw is set on the clamp in portion, is coordinated in screw and fixture bolt is installed, the draw-in groove of U-shaped card is engaged with clamp, passes through Fixture bolt make U-shaped fix be connected on clamp, the upper end of fixture bolt it is affixed horizontal hanging arm.

Concrete operations are as follows：

1）First copper pipe jig body is connected with crystallizer copper pipe clamp, then again copper pipe fixture screw rod fixation is tightened into；

2 are connected using steel cable with crystallizer copper pipe fixture, commander's driving lifting.

Effect is as follows：

After enforcement, the replacement operation of spray mold copper pipe is simple, reduces replacing construction, and originally copper pipe hangs out the time and is 6-8min, present copper pipe hangs out the time and only needs to 2-3min, the labor intensity of worker is reduced in certain degree, while disappearing The potential safety hazard fallen is slipped except crystallizer copper pipe hangs out.

This utility model is rational in infrastructure, simple to operate, it is possible to reduce replacing construction, reduces the labor intensity of worker, can be with Eliminate crystallizer copper pipe and hang out the potential safety hazard that slippage is fallen.

Description of the drawings

This utility model is further described below in conjunction with accompanying drawing, Fig. 1 is the signal of this utility model front view structure Figure, Fig. 2 is the structural representation of special hanger.

Specific embodiment
