Abstract
The utility model relates to a full suspension electronic conveyer-belt weigher, which is a weighing bearing device used for the continuous dynamic metering of bulk cargoes. A weighing supporting roller is arranged on a whole weigher frame, and four weighing sensors are symmetrically positioned at the two sides of the longitudinal beam of the weigher frame; the lower end of the weighing sensor is connected with the longitudinal beam of the weigher frame, and the upper part is connected with a transverse beam which is fixedly connected to the machine frame of a conveyer-belt machine to ensure the weigher frame be suspended in the frame of the conveyer belt machine through the four weighing sensors. The utility model has the advantages of reasonable structure, easy fabrication, and convenient installation and debugging. The system formed by the full suspension electronic conveyer-belt weigher and the weighing sensors is superior to 0.03% after detection, the formed electronic conveyer-belt weigher is superior to 0.25%, and is free from the restriction of fixed or movable conveyer-belt machines; even in harsh environment, the accuracy of the full suspension electronic conveyer-belt weigher is still up to 0.5%.
Description
The utility model relates to a kind of full suspension type belted electronic balance, belongs to continuous integration formula Automatic balance.
Belted electronic balance has been widely used in port and pier, the large amount bulk cargo continuous measurement of industries such as metallurgical mine.
In the prior art, constituting the belted electronic balance systematic error mainly is made up of the error of secondary instrument, LOAD CELLS, speed pickup and scale frame actuating system.Along with the countries in the world development of electronic technology, advanced technology such as micro computer, large scale integrated circuit is widely used in belted electronic balance, make its function constantly perfect, secondary instrument, sensor errors have been reduced to very low limit, will further improve system's accuracy of belted electronic balance, key is to reduce the error that scale frame actuating system causes.Present domestic and international normally used many roller-types of double lever scale frame, as: the 10-20-2 type scale frame of U.S. Ramsay company, Philips company, the BW2-1 that West Germany subsidiary company produces, BW2-2 type and East China Electronics Co., Ltd instrument plant 465 type double lever type scale framves etc. are all selected the level type scale frame of flexible support or elastic bearing and knife edge bearing for use, the force transferring structure of this scale frame is by two groups of symmetrical mutually levers, the weight of material that is born on the weighing carrier roller is delivered on the LOAD CELLS, therefore, this structure easily produces the power transmission error, influences the accuracy of belted electronic balance system.
The purpose of this utility model is, providing a kind of does not have fulcrum and torque as long as keep the appropriate location of weight scale frame, and locatees with the pull bar stop, and this scale frame movement-less part and wearing terrain can maintain a long-term stability reliably, and have again and make simply, debug loading holder easy for installation.
The utility model can reach by following measure, the roller rack that weighing carrier roller is housed places on the framework of being made up of scale frame longeron and scale frame crossbeam, four LOAD CELLS are positioned at two sides that claim the frame longeron to scale, the lower end of the biography of weighing device connects with scale frame longeron, top is connected with crossbeam, crossbeam is fixed on the frame of belt feeder, the scale frame is suspended in the frame of belt feeder by four LOAD CELLS, when working, take place all around to move for restriction scale frame simultaneously, adopt adjustable stop, scale frame and belt feeder frame are coupled together.
Fig. 1: be the full suspension type belted electronic balance
Describe in detail below in conjunction with legend.By scale frame crossbeam (1) and scale frame in length and breadth (3) form a framed structure, roller rack (7) is housed on the scale frame longeron (3), weighing carrier roller (6) is housed on the roller rack (7), the two ends of crossbeam (5) are fixed in respectively on the belt feeder frame (10), the lower end of four LOAD CELLS (4) is connected with scale frame longeron (3) respectively, top is connected with crossbeam (5) respectively, whole scale frame is suspended in the belt feeder frame, more effectively work for making LOAD CELLS (4), the installation site of LOAD CELLS (4) and scale frame crossbeam (1) are in the same vertical plane, and perpendicular to scale frame plane, it is mobile all around to consider that the scale frame is produced when belt feeder is worked, the spy is provided with stop and is located, the longitudinal spacing device is made up of nut (2) and location adjusting screw(rod) (8), one end of longitudinal spacing device is connected with scale frame crossbeam (1), the other end is connected with hanger (11) on the positioning beam (9), positioning beam (9) is fixed on the belt feeder frame (10), the cross spacing device one end of being made up of nut (13) and location adjusting screw(rod) (12) is connected with crossbeam (5), the other end is connected with scale frame longeron (3), vertically limit device and cross spacing device position are near LOAD CELLS (4), for further guaranteeing the accuracy of measuring of weighing system, the slenderness ratio of spacing adjusting screw(rod) is answered＞1:80, also adopted four sensor parallel connection methods simultaneously, made the sensor composition error reduce 1/2.
Because the utility model is a full suspension type scale frame, reduced the mechanical transfer error, make the leading indicators such as linearity of scale frame directly relevant with LOAD CELLS, irrelevant with load position, system's accuracy of the utility model and LOAD CELLS composition is better than 0.03% after testing, scale frame metering coverage is increased, and the belt influence of fluctuations greatly reduces, thereby obtains higher accuracy and stability.Accuracy is better than 0.25% through Shanghai Metrology Examine and Determine Office calibrating belt conveyer scale system, and is not subjected to fixing or mobile belt feeder limits, even use under rugged surroundings, its accuracy still can reach 0.50%.
Warp is tried out, and the utility model is rational in infrastructure, makes simply, and Installation and Debugging are convenient, measures with the supporting commerce that is directly used in of weighing instrument.With our company is example, calculates by a metering production line year metering tonnage 2,400,000.0.20 yuan of charge per ton, can take in 480,000 yuan the whole year, and changed rule of thumb and judge the primitive method of loading tonnage.Improved freight transport quality.
