Abstract
Collapsed protector the utility model discloses a kind of blast furnace, it is characterized in that including spiral rope, extension spring and travel switch, spiral rope is by blast furnace outer upper end around blast furnace helical arrangement to bottom house, along spiral rope track outside the blast furnace on support bar is distributed with, support bar outer end is connected with rope sheave, spiral rope falls in rope sheave, spiral rope upper end is fixed on the support bar on most, spiral rope lower end stretches straight to be connected with extension spring one end, the extension spring other end is connected with travel switch stroke lever, spiral rope tightens rear travel switch to disconnect by extension spring, spiral rope disconnects travel switch and resets closure, spiral rope is by thermal cutoff material；The utility model usually provides safety signal for equipment emergency system, and when blast furnace caves in or leaks, high temperature causes spiral rope to fuse, travel switch, which resets, connects closure, provides fault-signal for equipment emergency system, reliability is high, can with and alarm, protective range it is comprehensive.
Description
Technical field
A kind of metal smelt blast furnace safety protector is the utility model is related to, is collapsed protection more particularly to a kind of blast furnace
Device.
Background technology
Metal smelt industry, it is related to blast furnace when such as smelting iron, it is catastrophic accident that blast furnace, which collapses, how to be collapsed
When to cut off the supply of various materials and fuel in time be that existing equipment is mostly electronic equipment, is operated in an important factor for reducing loss
It is easy to fail under the adverse circumstances such as high temperature, causes fault detect failure, causes bigger catastrophic loss, this is still up for skill
Art solves.
Utility model content
In order to solve the above problems, the utility model provides a kind of blast furnace and collapsed protector.
The technical solution adopted in the utility model is：A kind of blast furnace collapses protector, it is characterised in that including spiral rope,
Extension spring and travel switch, spiral rope surrounds blast furnace helical arrangement to bottom house by blast furnace outer upper end, along spiral rope rail
Mark outside the blast furnace on support bar is distributed with, support bar outer end is connected with rope sheave, and spiral rope falls in rope sheave, and spiral rope upper end is consolidated
It is scheduled on the support bar on most, spiral rope lower end stretches straight to be connected with extension spring one end, the extension spring other end and stroke
Switch over travel bar connects, and spiral rope tightens rear travel switch to disconnect by extension spring, and spiral rope disconnects travel switch and resetted
Closure, spiral rope are by thermal cutoff material.
Further, the spiral rope is restricted for more than two strands.
Further, the spiral rope is two or more material ropes.
The utility model usually remains off in extension spring effect lower stroke switch, is provided for equipment emergency system
Safety signal, when blast furnace caves in or leaks, high temperature causes spiral rope to fuse, and travel switch, which resets, connects closure, should for equipment
Anxious system provides fault-signal, and reliability is high, can with and alarm, protective range it is comprehensive.
Brief description of the drawings
Fig. 1 is the utility model embodiment overall schematic.
Fig. 2 is the utility model embodiment support bar schematic diagram.
Reference:1 spiral rope；2 blast furnaces；3 support bars；4 rope sheaves.
Embodiment
The utility model embodiment as shown in Figure 1, 2, the blast furnace collapse protector provided with spiral rope 1, extension spring and
Travel switch, not depending on going out extension spring and travel switch in figure, spiral rope by the outer upper end of blast furnace 2 around blast furnace helical arrangement extremely
Bottom house, outside covering blast furnace, along spiral rope track outside the blast furnace on support bar 3 is distributed with, support bar outer end is connected with
Rope sheave 4, spiral rope falls in rope sheave, and spiral rope upper end is fixed on the support bar on most, and spiral rope lower end stretches straight and drawn
Spring one end connection is stretched, the extension spring other end is connected with travel switch stroke lever, row after spiral rope is tightened by extension spring
To disconnect, spiral rope disconnects travel switch and resets closure Cheng Kaiguan, and spiral rope is that spiral rope is fusing-off temperature by thermal cutoff material
Material below 200 degree, such as plastic cement, string, other synthetic materials.
The utility model usually remains off in extension spring effect lower stroke switch, is provided for equipment emergency system
Safety signal, when blast furnace caves in or leaks, high temperature causes spiral rope to fuse, and travel switch, which resets, connects closure, should for equipment
Anxious system provides fault-signal, and reliability is high, can with and alarm, protective range it is comprehensive.
During implementation, spiral rope is more than two strands and restricted, and improves reliability；Spiral rope is two or more material ropes, and internal layer can be with
It is to provide the material of preferable pulling force, internal layer can be to provide preferably ageing-resistant material, improve combination property.
It is only in summary the utility model preferred embodiment, all equivalent modification done according to the application and prior art add
Add and be accordingly to be regarded as the utility model technology category.
