Abstract
The invention provides a slab connection detecting device of continuous casting slabs and a detecting method thereof. The device comprises a mounting bracket, wherein an extension rod is mounted at the lower part of the mounting bracket; the lower part of the extension rod is connected with a heavy hammer through a chain; the heavy hammer is connected with a relay through a cable; the relay is connected with a delay relay; and the delay relay is connected with a PLC control system of a cutter. The device and the method can accurately judge the slab connection to bring convenience for timely treatment in the generation of slab connection so as to prevent such problems as the damage of a roller way and a motor and the jet printing of messy codes caused by the slab connection, so that the production quality of the slabs is improved.
Description
technical field:
The present invention relates to a kind of continuous casting steel billet and connect base checkout gear and detection method.
background technology:
Sheet billet continuous casting in process of production, needs to cut strand by the length of flame cutting machine according to setting.After cutting into slab, enter into next process.In cutting process, due to coal gas, the position of cutting gun, the factors such as edge correction position is inaccurate cause strand can't cut, thus cause slab to connect base.After appearance connects base, follow-up roller-way continues automatically to start, and will cause the damage of roller-way and motor.And owing to connecting base, follow-up slab information disorderly, causes spray printing code disorderly.Cause the disorder of logistics information.Therefore, detecting slab, to connect base necessary.At present, most of conticaster does not have slab to connect the detection of base.
summary of the invention:
The object of the invention is to provide a kind of continuous casting steel billet to connect base checkout gear and detection method for above-mentioned Problems existing, the company's base after slab caster cutting can be detected and be judged.
Above-mentioned object is realized by following technical scheme:
Continuous casting steel billet connects base checkout gear, comprise mounting bracket, expansion link is installed in described mounting bracket bottom, described expansion link bottom connects weight by chain, described weight connects relay by cable, described relay connects time-delay relay, and described time-delay relay connects the PLC control system of cutting machine.
Described continuous casting steel billet connects base checkout gear, and described mounting bracket top is provided with felt pad.
Described continuous casting steel billet connects base checkout gear, and described expansion link comprises outer tube and inner sleeve, and described inner sleeve to stretch in described outer tube and is bolted.
With above-mentioned continuous casting steel billet connect base checkout gear carry out conticaster slab connect base detect method, the method is: when slab caster has cut, when starting follow-up roller-way, cutting machine PLC sends and starts the company's of detection base signal weight and obtain electric, if slab normal cutoff, due to the movement of slab, weight will be made not touch slab, weight is unsettled, electric current will do not had to pass through, superincumbent relay of connecting will be failure to actuate, if do not cut off, electric current is had to pass through weight by continuing, because slab is connected with the earth, therefore, when weight contacts with slab, electric current will be had to pass through, trigger the actuating of relay be connected on above weight, if the duration exceedes the preset value of time-delay relay action, by obtaining electric time-delay relay action, " slab connects base " signal is transported to cutting machine PLC, this cutting is not cut off, have and connect base.
Beneficial effect:
The present invention can accurately judge to connect base, is convenient to occur processing in time when connecting base, and companys of avoiding base causes the problems such as the damage of roller-way and motor and spray printing mess code, improves the slab quality of production.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
[0011]in figure: mounting bracket 1; Expansion link 2; Chain 3; Weight 4; Relay 5; Time-delay relay 6; The PLC control system 7 of cutting machine; Felt pad 8.
detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further described.
Embodiment 1:
As shown in Figure 1: continuous casting steel billet of the present invention connects base checkout gear, comprise mounting bracket 1, expansion link 2 is installed in described mounting bracket bottom, described expansion link bottom connects weight 4 by chain 3, described weight connects relay 5 by cable, described relay connects time-delay relay 6, and described time-delay relay connects the PLC control system 7 of cutting machine.By integral installation of the present invention on the lowering or hoisting gear of cutting machine, continuous casting steel billet start to cut time, cutting machine itself will drop to main pressure position, this device along with cutting machine lifting device decline and decline, weight is contacted with the strand cut.After making cutting machine lifting device drop to cutting position by expansion link adjustment, weight just in time contacts with the strand cut.
Embodiment 2:
Continuous casting steel billet described in embodiment 1 connects base checkout gear, and described mounting bracket top is provided with felt pad 8.Arranging felt pad avoids this device to mix with the electrical system of cutter body.
Embodiment 3:
Embodiment 1 or the continuous casting steel billet described in embodiment 2 connect base checkout gear, and described expansion link comprises outer tube and inner sleeve, and described inner sleeve to stretch in described outer tube and is bolted.
With above-mentioned continuous casting steel billet connect base checkout gear carry out conticaster slab connect base detect method, the method is: when slab caster has cut, when starting follow-up roller-way, cutting machine PLC sends and starts the company's of detection base signal weight and obtain electric, if slab normal cutoff, due to the movement of slab, weight will be made not touch slab, weight is unsettled, electric current will do not had to pass through, superincumbent relay of connecting will be failure to actuate, if do not cut off, electric current is had to pass through weight by continuing, because slab is connected with the earth, therefore, when weight contacts with slab, electric current will be had to pass through, trigger the actuating of relay be connected on above weight, if the duration exceedes the preset value of time-delay relay action, by obtaining electric time-delay relay action, " slab connects base " signal is transported to cutting machine PLC, this cutting is not cut off, have and connect base.
