Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
In describing the invention, it should be noted that, except as otherwise noted, the implication of " multiple " is two or more; Term " on ", D score, "left", "right", " interior ", " outward ", " front end ", " rear end ", " head ", the orientation of the instruction such as " afterbody " or position relationship be based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.In addition, term " first ", " second ", " the 3rd " etc. only for describing object, and can not be interpreted as instruction or hint relative importance.
In describing the invention, also it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, visual concrete condition understands above-mentioned term concrete meaning in the present invention.
The present invention discloses a kind of online weighing roller-way, comprises rollgang 4, and described rollgang 4 is evenly provided with multiple roller 2, and described rollgang 4 is provided with one or more pairs of shear force sensor 12, and multiple described shear force sensor 12 forms measurement zone; Workpiece 5 to be weighed passes through described measurement zone under the rotary action of described roller-way.Region shown in the dotted line of Fig. 2-4 is measurement zone.
Embodiment one:
As shown in Figure 2, based on foregoing, concrete, described shear force sensor 12 arranges a pair, and does not establish support column 6 in described measurement zone.Be arranged between two adjacent support columns 6 by measurement zone, so only need a pair shear force sensor 12 can realize detection of weighing.
Because shear force sensor 12 is directly installed on original rollgang 4, do not need to block rollgang 4, without the need to transforming rollgang 4 during installation, do not need to increase foundation of civil work, without the need to hydraulic system, cost of weighing is low.
When weighing, workpiece 5 to be weighed moves to after in measurement zone completely, and roller 2 stops operating, workpiece 5 no longer moves, shear force sensor 12 detects Parameters variation, and the weight that this variable quantity is corresponding is the weight of workpiece 5, and the precision weighed when workpiece 5 is static can reach one thousandth; Can not certainly stop roller 2 directly to weigh, this weighting manner workpiece 5 does not stop, and weighing precision can reach 3/1000ths.
Embodiment two:
As shown in Figure 3, the present embodiment is substantially identical with embodiment one, difference is the support column 6 be provided with in described measurement zone for supporting described rollgang 4, the both sides of support column 6 described in every root are equipped with at least one pair of shear force sensor 12, and are provided with at least one pair of shear force sensor 12 between adjacent two support columns 6.
Figure 3 shows that in measurement zone the schematic diagram only having a support column 6, the impact of support column 6 weighing results can be got rid of like this, the actual value of workpiece 5 weight will can be obtained after the testing result integrated treatment of multipair shear force sensor 12, measurement result is unaffected, can measure the larger workpiece of length 5.
Embodiment three:
As shown in Figure 4, the present embodiment is substantially identical with embodiment one, and difference is, is provided with support column 6 in described measurement zone, and described support column 6 is connected with pressure sensor 11.Concrete, described pressure sensor 11 is arranged on the bottom of described support column 6.
By arranging pressure sensor 11 on support column 6, the quantity that shear force sensor 12 is arranged can be reduced, only need to arrange a pair shear force sensor 12 at the ragged edge of detection zone, the roller-way distortion at support column 6 place carries out additional survey by pressure sensor 11, so still, need not block original rollgang 4, only need to transform support column 6, improvement cost is well below existing weighing structure of directly blocking rollgang 4, transformation speed is fast, and cost is low; Pressure sensor 11 is arranged on the bottom of described support column 6, pressure sensor 11 is away from rollgang 4, the temperature impact of high temperature strand on pressure sensor 11 is very little, and therefore the testing result of pressure sensor 11 not temperature influence, can obtain high-precision testing result.
Preferably, in above-mentioned three embodiments, the width of described measurement zone is greater than the length of described workpiece 5, to ensure the accuracy of measurement result.
Preferably, described shear force sensor 12 is all arranged on the side of described rollgang 4.The running of rollgang 4 need not be stopped during installation, do not affect manufacturing schedule; Installation site is exposed, and installs, disassembling section is all more convenient, and service speed is fast, and installing/dismounting efficiency is high.
Concrete, described workpiece 5 is casting blank of continuous casting machine.Namely the strand that online weighing roller-way of the present invention is preferred for conticaster is weighed.
As can be seen from the above embodiments, the present invention installs the weighing structure of shear force sensor 12 on rollgang 4 by adopting, under the prerequisite of not blocking rollgang 4, can install, without the need to increasing foundation of civil work, not needing hydraulic system, improvement cost being installed low; Only in the side of rollgang 4, one or more pairs of shear force sensor 12 need be installed simply during installation, can online weighing be realized, simple installation; Without the need to blocking rollgang 4, rollgang 4 can infinitely extend in theory, and measurement zone can be arranged on any place on rollgang 4 as required, can meet the demand of different operating mode; Shear force sensor 12 is arranged on the side of rollgang 4, and shear force sensor 12 installation site is exposed, and during installation or removal, rollgang 4 does not need to shut down, the operation of handled easily personnel; For the operating mode that detection zone is longer, the impact at support column 6 place can by increasing the logarithm of shear force sensor 12, or arrange pressure sensor 11 at support column 6 place and compensate, to get rid of the impact of support column 6 weighing results; Pressure sensor 11 is arranged on the bottom of described support column 6, pressure sensor 11 is away from rollgang 4, the temperature impact of high temperature strand on pressure sensor 11 is very little, and therefore the testing result of pressure sensor 11 not temperature influence, can obtain high-precision testing result.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
