Relate to the field
The utility model relates to the pick-up unit of molten iron in a kind of steel industry or molten steel weight, is in particular a kind of with 100 tons of no foundation ditches, constantly the rail weighing unit is the weighing device of benchmark.
Background technology
Along with the development of steel industry has been subjected to general attention to the detection of molten iron in the production run or molten steel weight, molten iron and molten steel adopt hot-metal ladle and carriage (or molten iron torpedo tank car) and ladle car loading.The mode of measuring has: a kind of is foundation ditch formula track scale, and another kind is no foundation ditch, continuous rail track scale.Foundation ditch formula track scale is when measuring the weight of liquid material, the lateral impact forces of liquid sloshing is bigger, do not have fish platee to be connected owing to the weighting platform rail with outside rail again, the rail on weighting platform after the impact that is subjected to vehicle is climbed the rail phenomenon, thereby causes the system accuracy misalignment and drive a vehicle dangerous.In addition when measuring the weight of molten iron or molten steel, because molten iron or molten steel outer spatters " by blocking " of often causing weighting platform, influencing system accuracy has increased maintenance workload simultaneously, and this mode is abandoned by the user gradually.At the problems that the foundation ditch track scale is arranged do not have foundation ditch, constantly the rail track scale is developed.Because the maximization of steel industry, the load of its hot-metal ladle and carriage or molten iron torpedo tank car is substantially more than 200 tons, this all brings a lot of problems for production, debugging and the demarcation of weighing-appliance: manufacturer does not have large-tonnage commissioning device like this and calibration facility, the user does not have corresponding standard equipment yet, therefore is difficult to guarantee the precision index of weighing system.
Summary of the invention
The purpose of this utility model is to provide a kind of all load to be equal to or greater than 200 tons hot-metal ladle and carriage for the above-mentioned defective that solves prior art or 100 tons weighing unit is resolved in the weight measurement of ladle car, and then be superimposed as complete vehicle weight with 100 tons of no foundation ditches, constantly the rail weighing unit is the weighing device of benchmark.
The purpose of this utility model can realize by following technical solution:
A kind of is the weighing device of benchmark with 100 tons of no foundation ditches, continuous rail weighing unit, it includes hot-metal ladle and carriage, rail, filling type force cell, out of shape, wherein said out of shape includes support body, at least one wheels, the load of described single wheels is 100 tons, each wheels is made of 4 wheels of twin shaft, each the wheel position place that is positioned at each wheels in rail is equipped with two semibridge system filling type force cells, and aforementioned structure constitutes 100 tons of no foundation ditches, continuous rail weighing unit.
The purpose of this utility model also can further realize by following technology solution:
Aforesaid is the weighing device of benchmark with 100 tons of no foundation ditches, continuous rail weighing unit, and wherein said wheels are two, four, eight.
Aforesaid is the weighing device of benchmark with 100 tons of no foundation ditches, continuous rail weighing unit, wherein said semibridge system filling type force cell is a triangular filling type force cell, it includes power transmission rib, shell, the responsive sheet of dynamometry, resistance strain plate, be fixedly connected with three power transmission ribs on the shell, the angle between described each power transmission rib is 120 degree.
Aforesaid is the weighing device of benchmark with 100 tons of no foundation ditches, continuous rail weighing unit, and the periphery of the responsive sheet of wherein said dynamometry is connected with the inner surface of outer cover interference fit, and described resistance strain gage is bonded on the responsive sheet of dynamometry.
Advantage of the present utility model is that it is load can be equal to or greater than 200 tons hot-metal ladle and carriage or 100 tons the composite set of weighing is resolved in the weight measurement of ladle car that the load of each weighing unit is 100 tons, and then be superimposed as complete vehicle weight, it is simple in structure, weighs accurately, and is easy to use.Sensor 3 is owing to be designed to three " ribs " simultaneously.Therefore sensor is to rely on three seamed edges with being connected of rigidity body structure, and the external force that acts on like this on the rigidity body can be delivered on the force cell uniformly.Because three-point support is the most stable support pattern, therefore can very big effect be arranged to linear error and the hysteresis that improves sensor, be used in combination semibridge system filling type force cell in pairs, can reach certain measurement Ping Qu, make measurement more accurate.
The purpose of this utility model, advantage and characteristics will illustrate and explain that these embodiment only provide as an example by the unrestricted explanation of following preferential embodiment.
