Abstract
The invention relates to a detection warning device used when an electric furnace tilts and outputs steel and track deviation happens, in particular to an anti-derailing electric furnace tilting warning device. The device comprises a tilting arc guide rail, and is characterized in that two auxiliary guide rails are fixed to one side of the tilting arc guide rail; each auxiliary guide rail is provided with a fixing support, a limiting switch is installed on each fixing support, and the limiting switches are connected to an alarm. The warning device is unique in structure and can effectively prompt production operators to correct in time, avoid accidents and guarantee safety and reliability of electric arc furnace smelting production.
Description
Technical field
The present invention relates to a kind of for electric arc furnaces fascinate tapping time there is course deviation time the device of detection alarm, especially relate to a kind of electric furnace and to fascinate derailing warning device.
Background technology
Smelting equipment comprises electric arc furnaces, refining furnace, intermediate frequency furnace etc., and the large-tonnage smelting equipment of more than 20 tons all exists tapping angle of fascinating, and when smelting tapping once fascinate course deviation and center of gravity unstability, will cause the accident, consequence is serious.
Also do not overcome the device of above-mentioned defect at present.
Summary of the invention
The object of the invention is the defect overcoming prior art, provide a kind of structure unique, can effectively point out production operation personnel to correct in time, avoid accident to occur, ensure that a kind of electric furnace of the security reliability of electric arc furnace smelting production fascinates derailing warning device.
The present invention realizes in the following way:
A kind of electric furnace fascinates derailing warning device, it comprises the camber line guide rail that fascinates, and it is characterized in that: be fixed with two auxiliary guide rails in described camber line guide rail side of fascinating, every bar auxiliary guide rail is respectively equipped with fixed support, fixed support is provided with limit switch, and limit switch is connected with an alarm;
Described limit switch is formed in parallel by preposition limit switch and rearmounted limit switch;
Described limit switch is parallel with described auxiliary guide rail;
Described fixed support fascinates on direction along tapping described limit switch is installed.
The present invention has following effect:
1) structure is unique: electric furnace provided by the invention fascinates derailing warning device, it comprises the camber line guide rail that fascinates, it is characterized in that: be fixed with two auxiliary guide rails in described camber line guide rail side of fascinating, every bar auxiliary guide rail is respectively equipped with fixed support, fixed support is provided with limit switch, and limit switch is connected with an alarm; Described limit switch is formed in parallel by preposition limit switch and rearmounted limit switch.
2) production operation personnel can be effectively pointed out to correct in time, accident is avoided to occur, ensure the security reliability that electric arc furnace smelting is produced: device provided by the invention utilizes electrical equipment sensing device to monitor electric furnace steel tapping trail change in time at this device of use procedure, once fascinate, tapping running orbit offsets, touch limit switch, alarm gives the alarm, and alert stops fascinating tapping, and checking fixes a breakdown stops accident generation.Production operation personnel effectively can be pointed out to correct in time, avoid accident to occur, ensure the security reliability that electric arc furnace smelting is produced.
3) the present invention is in use, simplicity of design, with low cost, be convenient to check, be convenient to safeguard, be suitable for promoting at high-risk smelting industry.After intelligent regeneration is carried out to electric arc furnaces, there is not the accident of similar derailing when tapping of fascinating in actual production, ensure that safety in production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is for being electric arc furnaces derailing warning device schematic diagram of the present invention.
Detailed description of the invention
A kind of electric furnace fascinates derailing warning device, it comprises the camber line guide rail that fascinates, as shown in Figure 1: be fixed with two auxiliary guide rails 6 in described camber line guide rail 7 side of fascinating, every bar auxiliary guide rail 6 is respectively equipped with fixed support 4 and 5, fixed support is provided with limit switch, and limit switch is connected with an alarm 1.
Limit switch is formed in parallel by preposition limit switch 2 and rearmounted limit switch 3.
Described limit switch is parallel with described auxiliary guide rail 6.
Described fixed support fascinates on direction along tapping described limit switch is installed.
Device provided by the invention, operates as follows:
1. easy to operate, alarm is fixed in the eye-catching position being convenient to observe, and is protected;
2. two auxiliary guide rails are fixed at, 1.8 meters, arc-shaped guide rail side of fascinating;
3. difference welded limiting switch fixed support on auxiliary guide rail;
4. at the preposition limit switch of support installing and rearmounted limit switch.
5. import after 220V power supply is connected and complete installation, then debug, debug qualified after can come into operation.During debugging, first manual debugging, pulls limit switch gently respectively with hand, adjusts warning gap after obtaining alarm signal, prevent excesssive gap or too small, and will guarantee that its sensitivity is reliable, avoids false alarm.Then carry out machinery to fascinate debugging, mainly carry out the debugging of auxiliary guide rail ruuning situation.
When fascinate tapping time arc-shaped guide rail and the fascinating maximum angle that to circle round between arc-shaped guide rail base that fascinates be: 15 °, direction of slagging tap, 45 °, direction of tapping, define the running orbit of electric furnace when fascinating.
Electric arc furnaces derailing warning device schematic diagram as shown in Figure 2, comprises preposition limit switch 2, rearmounted limit switch 3, alarm 1.Main power source is 220V, connects alarm loop when 2 or 3 limit switches are touched, and audible-visual annunciator 1 glimmers and reports to the police.
Fig. 1 structural representation of the present invention, wherein 1-alarm, the preposition limit switch of 2.-, the rearmounted limit switch of 3-, 4,5-fixed support, 6-auxiliary guide rail, 7-fascinates camber line guide rail, 8-converter body support, 9-body of heater.
Claims (4)
