Abstract
The invention relates to a method for measuring the width of a steel billet by utilizing a pair of hoisting pincers, comprising pincers with equidistant pincer arms. The method is characterized in that a guyed encoder is fixedly arranged on one pincer arm, a pothook is fixedly arranged on the other pincer arm and used for fixing a guyed head of the guyed encoder, a guyed rope of the guyed encoder is parallel to the surface of the steel billet that is clamped on the pincers, and the width of the steel billet clamped on the pincers can be calculated according to the change of guyed data of the guyed encoder. The width of the steel billet can be instantly calculated according to variable values of the guyed encoder while the billet is hoisted; the hoisting personnel and the quality control personnel can obtain the width of the steel billet instantly without contacting the steel billet and measuring by hands, thereby not only the working efficiency of th loading personnel is improved, but also repeated hoisting caused by measurement loss, examination omission, hoisting errors, and the like is reduced, the energy is saved, the consumption is reduced, the phenomenon that a heating furnace is vacant due to hoisting errors is avoided, and the rolling working efficiency is improved.
Description
Technical field:
The present invention is mainly used in the width that smelter steelworks, steel rolling mill's raw material steel billet handling are measured steel billet immediately.
Background technology:
At hot rolling mill, the measurement of width of steel billet is requisite Interventions Requested before the steel rolling, because steel billet reservoir area temperature height, multilayer buttress such as puts at reason, it can only be to hang on the roller-way to measure before steel rolling that blank width is measured, concrete measuring method is: by extension clamp under the half gantry crane car with the handling of raw material steel billet to furnace charging table, the advanced enterprise of equipment can utilize the laser width gage to measure, the enterprise of condition difference can only be by artificial tape measure, no matter adopt which kind of measuring method, in actual production process, the capital has part not meet the Billet trolley of production standard to roller-way, through the laser width gage, artificial tape measure is measured and is hung down roller-way again after width is not inconsistent, and then causes the local empty stove of heating furnace, influences problems such as rhythm of production, both influence work efficiency, caused the waste of repetition handling equal energy source again; How to learn blank width in advance, avoid invalid handling, increasing work efficiency is urgent problem.
Summary of the invention:
The present invention aims to provide a kind of method that just can measure the measurement width of steel billet of width of steel billet when utilizing extension clamp handling steel billet under the half gantry crane car.
Realize that technical scheme of the present invention is: comprise tong arm, jaw, it is characterized in that being installed with on one of them tong arm the stay-supported scrambler, be installed with hook on another tong arm, hook is used for fixing the pull wire head of stay-supported scrambler, the billet surface of clamping is parallel on the backguy of stay-supported scrambler and the clamp, the variation of the backguy data by the stay-supported scrambler can calculate the width of the folded steel billet of clamp.
The tong arm of described clamp is isometric.
The present invention also comprises and matching used S7-300 data processor of stay-supported scrambler and computing module thereof, by display data is exported.
Shown in Figure 2, the principle of operation of the S7-300 data processor among the present invention is: the O point is the axle center of clamp, the position of stay-supported scrambler when the A point does not press from both sides steel billet for clamp, the position of the pull wire head of stay-supported scrambler when the B point does not press from both sides steel billet for clamp, the position of jaw when C, D point does not press from both sides steel billet for clamp, A
1The position of stay-supported scrambler when point presss from both sides steel billet for clamp, B
1The position of the pull wire head of stay-supported scrambler when point presss from both sides steel billet for clamp, C
1, D
1The position of jaw when point presss from both sides steel billet for clamp, the principles well-known similar according to triangle can get mathematical expression:
Because: H is line segment C
1D
1, be the width of steel billet of measuring; H
OBe line segment CD, the measured value when not pressing from both sides steel billet for clamp; A is line segment AO or A
1O is the length of gripper encoder to axle center O; B is line segment CO or C
1O or D
1O is the length of steel billet contact point to axle center O; Δ h=Δ h/2+ Δ h/2 is encoder measurement; h
OBe line segment AB, the measured value of stay-supported scrambler when not pressing from both sides steel billet for clamp; H is line segment A
1B
1, the measured value of stay-supported scrambler during for clamp folder steel billet.
Above-mentioned equation can be expressed as:
Can draw the width of steel billet computing formula and be by separating above-mentioned equation
H＝H0+b÷a×Δh
Consider the installation quality of fit of field apparatus, consider certain round-off error δ, (the actual measurement mean value that this value is regularly proofreaded for production run changes along with equipment operation condition).
Actual width of steel billet computing formula is modified to
H＝H
O+b÷a×Δh+δ
The utility model has the advantages that: in the handling steel billet,, can calculate the width of steel billet immediately by the changing value of stay-supported scrambler; Handling personnel, quality inspection personnel need not contact steel billet, without hand dipping, can learn width of steel billet immediately, have both improved material loading personnel's work efficiency; Reduced the repetition handling that takes place because of the omission of examination of lapsing, handling mistake etc. again, energy-saving and cost-reducing; Avoid the generation of the heating furnace room phenomenon that causes because of the handling mistake, improved rolling work efficiency.
Description of drawings:
Fig. 1 is the structural drawing of the embodiment of the invention.
Fig. 2 is the schematic diagram calculation of the embodiment of the invention.
Among the figure: 1. 6. rotating shafts, 7. steel billets, 8. overhead traveling crane travelling cars are linked up with in the 4. scrambler backguys 5. of scrambler 2. tong arms 3. tong arms
Embodiment:
Embodiment: shown in Figure 1, present embodiment is to carry out on the clamp of the handling steel billet that hot continuous rolling factory of Shanxi Taigang Stainless Steel Co., Ltd uses at present, the jig arm symmetry of this clamp, clamp comprises tong arm, jaw, two bolts are welded in the position apart from clamp rotating shaft 6 axle center 80mm of a tong arm 2 therein, be installed with the miniature stay-supported scrambler 1 of YK6 type on the bolt, the height of bolt and scrambler is 50mm; Be installed with hook 5 in the position apart from clamp rotating shaft 6 axle center 130mm of another tong arm 3, hook 5 is used for fixing the pull wire head of stay-supported scrambler; During Installation and Debugging, guarantee scrambler backguy exit point to distance of shaft centers from the pull wire head point of fixity to distance of shaft centers from equating, be parallel to billet surface with the backguy of assurance.
