Fig. 1 is the utility model structural representation;
Fig. 2 is the static steel billet of the utility model part-structure schematic diagram of weighing.
Mark is as follows among the figure: pallet 1, pull bar 2, sensor 3, support 4, the platen 5 of weighing, basis 6, roller-way beam 7, lifting hydraulic cylinder 8, carrying roller 9, dish spring 10, spheric washer 11, taper faced washer 12.
The specific embodiment
The utility model send roller-way part, the static steel billet part of weighing to form by liftable heat, liftable heat send roller-way partly to comprise roller-way beam 7, lifting hydraulic cylinder 8 and carrying roller 9, and static steel billet is weighed and partly comprised pallet 1, pull bar 2, sensor 3, support 4 and the platen 5 of weighing.
Show among the figure, liftable heat send the carrying roller 9 of roller-way part to be arranged on roller-way beam 7, and continuous casting billet is placed on the carrying roller 9.8, two lifting hydraulic cylinders 8 of two lifting hydraulic cylinders are installed below roller-way beam 7 are laid respectively at two ends, roller-way beam 7 bottom.
When continuous casting billet is placed on the carrying roller 9, the decline by lifting hydraulic cylinder 8 is so that roller-way beam 7 descends, and continuous casting billet is placed on the pallet 1 and carries out weighing, and lifting hydraulic cylinder 8 rose after weighing was finished, and treats that the rise butt roller 9 that puts in place of roller-way beam 7 is sent to continuous casting billet and rolls the district.
Show among the figure, the weigh pallet 1 of part of static steel billet is three, and uniform along the direction of roller-way beam 7 respectively, the upper end of pallet 1 is between two roller-way beams 7, when roller-way beam 7 rises, the upper end of pallet 1 is lower than the surface of carrying roller 9, can not contact with continuous casting billet, when roller-way beam 7 descends, the upper end of pallet 1 is higher than the surface of carrying roller 9, pallet 1 is held continuous casting billet and is weighed, and support 4 is passed at the middle part of pallet 1, and the lower end of pallet 1 is rigidly connected with the platen 5 of weighing.
Show among the figure, the weigh support 4 of part of static steel billet is two, and two supports 4 lay respectively at two ends, roller-way beam 7 below, and support 4 has a crossbeam and two lateral braces, the lower end of two lateral braces is fixed on the basis 6, and the crossbeam two ends of support 4 are connected with an end of sensor 3 by pull bar 2.
Show among the figure, the platen 5 of weighing is two, and two platens 5 of weighing are I-steel, below roller-way beam 7 with the 7 parallel placements of roller-way beam.Platen 5 two ends of weighing are connected by the other end of pull bar 2 with sensor 3, and the platen 5 that is equivalent to weigh is hung on the support 4 by pull bar 2 and sensor 3, and support 4 becomes the fulcrum of weighing.Platen 5 is rigidly connected with the lower end of pallet 1 owing to weighing, and when pallet 1 is subject to the continuous casting billet pressure drop, will drive the platen 5 of weighing descending, and the platen 5 of weighing is weighed by pull bar 2 pulling sensors 3.
Show among the figure, sensor 3 is four, is divided into two groups, is installed in respectively two supports 4 at two ends, roller-way beam 7 below and weighs between the platen 5, and the signal output part of sensor 3 is connected with the computer processor unit of weighing.
Show among the figure, in order to guarantee 3 power that are subjected to vertical direction of sensor, be not subjected to the impact of the power of other direction, sensor 3 adopts the jockey of particular design, the pull bar 2 of top support 4 and sensor 3 is connected with taper faced washer by spheric washer 11 and is connected, and weigh pull bar 2 employings of platen 5 and sensor of below are hinged.The design of sensor 3 takes into full account the abominable environment for use of sensor, and the aspects such as transmission of the protection of holding wire and accurate signal, adopts high accuracy waterproof pulling type sensor.
Show among the figure, between the upper end supporting plate of pallet 1 and the tray bar dish spring 10 is installed, adopt dish spring 10 to weaken continuous casting billet to the impact of pallet 1.
The utility model overcomes the defectives such as mechanical stability, poor repeatability and weighing precision that two kinds of weight methods of carrying roller lift weight method and whole roller-way weight method exist are low, carrying roller lift weight method and whole roller-way weight method thought are combined, design a kind of efficient, accurate, static automatic weighing device.Whole automatic weighing device mechanical part is comprised of two parts: but the heat of automatic lifting send roller-way and static steel billet to weigh.This device belongs to " static weighing ", and namely sensor and support are actionless.Below heat is sent the roller-way beam, install lower position switch, realize that by hydraulic lifting executing agency heat send roller-way automatically to rise when crossing steel, heat send roller-way automatically to descend when weighing.
The utility model software section mainly is comprised of Siemens S7-300 PLC and WINCC software.Heat is sent roller-way to descend and after steel billet is stable steel billet is weighed, and weight signal constantly passes to the PLC system of weighing, and data communication device is crossed digital filtering technique and processed, and is accompanied by heat and send roller-way to rise system's data acquisition, analysis, transmission course.
Because steel billet claims the length span to reach more greatly hot continuous casting billet and have continuous the shake in the weighing process, so that data existence fluctuation in the weighing process, field data shows that fluctuating is the sinusoidal decay waveform, carries out the digital filtering processing to this waveform.After heat sent roller-way to descend, the beginning image data was tentatively filtered end to end to data first, determines the preliminary scope of data to be analyzed.Data in the preliminary scope are sorted, abandon abnormal data, carry out the data filtering second time.The secondary filter data are carried out logical operation, calculate the weigh of strand and finish data output.
The utility model device weighing precision is high, and weighing error is less than 1.5Kg(0.6 ‰).Implement the strand Weight-fixing cutting and can obviously improve rolling lumber recovery, reduce rolling non-scale material, the enterprise whole economic efficiency.
