Particularly, described support unit comprises at least two n shape base supports and is erected at two bases on the described base support.
Further, described weighing unit comprises at least four LOAD CELLS and is erected at four special uses on the LOAD CELLS and claims frame, and four described LOAD CELLS are symmetrically distributed on four angles of described base.
Particularly, described lifting unit comprises two groups of initiatively lifting structure and two groups of passive lifting structures at least, and initiatively lifting structure and passive lifting structure interval arrange; Initiatively lifting structure and passive lifting structure are connected to form interlock by pull bar.
Further, described active lifting structure comprises bearing and the rotating shaft assembling that is arranged on the described special-purpose title frame at least, be arranged on the hydraulic cylinder on the described bearing, be connected to the first connecting rod on the described hydraulic cylinder homalocephalus, be connected to the rotating shaft assembling of the first connecting rod other end, be arranged on the second connecting rod of described rotating shaft fit on, be connected to the hinge of described second connecting rod, be hung on two third connecting rods at described hinge two ends, two the 4th connecting rods that are connected with described third connecting rod by screw rod and nut, be arranged on the trailing arm of two described the 4th connecting rod ends, and be arranged on the 5th connecting rod in the rotating shaft of described rotating shaft assembling.
Further, described passive lifting structure comprises the rotating shaft assembling that is arranged on the described special-purpose title frame at least, be arranged on the second connecting rod of described rotating shaft fit on, be connected to the hinge of described second connecting rod, be hung on two third connecting rods at described hinge two ends, two the 4th connecting rods that are connected with described third connecting rod by screw rod and nut, be arranged on the trailing arm of two described the 4th connecting rod ends, be arranged on the 5th connecting rod in the rotating shaft of described rotating shaft assembling, and the pull bar that is used for connecting described the 5th connecting rod and adjacent active lifting structure the 5th connecting rod.
The LOAD CELLS of steel billet weight scale of the present invention is contained in the top away from roller-way, and without impact, weighing precision is higher to sensor for steel billet, long service life.And by different combinations of holding in the palm the steel arms, can realize the weighing of different length steel billet, and range of weighing is wide, and easy care and efficient are higher.Weight scale is finished by the action of hydraulic cylinder and is connect steel, weighing and send the step such as steel, steel billet to sensor without impact, weighing precision is high.And the combination by different trailing arms, can realize the weighing of different length steel billet, revise the shape of trailing arm pop-up steel face, the weighing of the steel billets such as ponderable quantity rectangular bloom, circle base.
Description of drawings
Fig. 1 is preferred embodiment of the present invention front view.
Fig. 2 is preferred embodiment left view shown in Figure 1.
Embodiment
Below in conjunction with Figure of description and preferred embodiment the present invention is described in detail.
As depicted in figs. 1 and 2, steel billet weight scale of the present invention comprises a base 10 and four LOAD CELLS 11, and base 10 is located at longitudinally centre position of roller-way, and base support 20 is crossed on the roller-way both sides.Four LOAD CELLS are bearing on the base 10, are provided with a special-purpose frame 1 that claims four LOAD CELLS.Claim frame 1 that four rotating shaft assemblings 9 are housed in special use, the top of two rotating shaft assemblings 9 therein is equipped with a hydraulic cylinder 4.The bearing 2 of hydraulic cylinder 4 is contained on the special-purpose title frame 1, and the homalocephalus of hydraulic cylinder 4 links to each other with an end of first connecting rod 8 by bearing pin, and the other end of first connecting rod 8 is connected with the rotating shaft of rotating shaft assembling 9.Assemble 9 tops in each rotating shaft and be provided with second connecting rod 7, second connecting rod 7 is connected with hinge 12.All hang with third connecting rod 6 and the 4th connecting rod 16 at hinge 12 two ends, are connected connection with nut by screw rod 13 in the middle of third connecting rod 6 and the 4th connecting rod 16.The bottom of two the 4th connecting rods 16 is connecting trailing arm 15.The rotating shaft of each rotating shaft assembling 9 is provided with the 5th connecting rod 5, connects by pull bar 3 between each connecting rod 5, forms interlock.
Workflow: steel billet stops at roller-way after entering the weighing district, and hydraulic cylinder rises trailing arm by coacting of connecting rod, pull bar.Steel billet leaves the roller-way face under the lifting of trailing arm, LOAD CELLS then weighs up the quality of steel billet.Hydraulic cylinder is fallen trailing arm after measuring, and steel billet is got back on the roller-way, by roller-way steel billet is sent to heating furnace subsequently.Steel billet length more available B, C trailing arm holds up steel billet and carries out weighing, when longer then available A, B, C carry out weighing, can carry out together weighing with A, B, C, D when the longest.Therefore its range of weighing is wider, and whole weighing process is finished by hydraulic cylinder, moves soon and stable action.
The LOAD CELLS of steel billet weight scale of the present invention is installed on the base away from roller-way, and steel billet without impact, has prolonged the serviceable life of the equipment such as LOAD CELLS to sensor like this, be convenient to again safeguard, it is more accurate to measure, and easily is automated, improve work efficiency, reduced cost.By the combination of different trailing arms, can realize the weighing to the different length steel billet, revise the shape of trailing arm holder steel face, the weighing of the steel billets such as ponderable quantity rectangular bloom, circle base.
Above; be preferred embodiment of the present invention only, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
