Abstract
The invention relates to railway locomotive manufacturing and maintenance equipment, in particular to an automatic aligning and weighing system for a locomotive bogie. Weighing devices are installed at cutoff positions of a weighing platform track I (6) and a weighing platform track II (7) corresponding to the positions of front wheels and rear wheels of a bogie (1). Each weighing device consists of weighing modules, rim tracks, a horizontal track, laser ranging sensors and displacement servo systems. The laser ranging sensors are installed on the internal sides of wheels. Distance from the laser ranging sensors and the internal side surfaces of the wheels are respectively measured. After computation is conducted, the results are fed into the displacement servo systems. Servo motors drive the weighing modules to be properly adjusted on the horizontal track. Therefore, the deviation of the measured values of the same bogie which is pushed in for multiple times is minimized and the repetitive measurement accuracy of the measurement system is improved.

Embodiment
In conjunction with accompanying drawing this example is described:
Accompanying drawing 1,2,3,4,5,6
Present embodiment: the automatic contraposition weighing system of engine truck is installed weighing device to the position by the truncated position at the front and rear wheel of weighing unit track I 6 and weighing unit track II 7 corresponding bogies 1.
Former and later two compositions of taking turns the weighing device that the position is installed are the same; The existing weighing device of installing with the trailing wheel contraposition place of putting is explained; The weighing device left side is Weighing module I 5, and Weighing module I 5 bottoms are cross track I 9, so that Weighing module I 5 laterally moves on cross track I 9; The magnetic railings ruler read head is installed on the Weighing module I 5, on cross track I 9, magnetic railings ruler is installed.
The right side of weighing device is Weighing module II 4, and Weighing module II 4 bottoms are cross track II 8, so that Weighing module II 4 laterally moves on cross track II8, Weighing module II4 goes up the magnetic railings ruler read head is installed, and on cross track II8, magnetic railings ruler is installed.
Weighing module I 5 inboard dress wheel rim rail I 13; Weighing module II 4 inboard dress wheel rim rail II 14.The forward and backward weight of bearing wheel so that weigh.
Weighing module I 5 is connected with displacement servo-drive system I 11, and the laser range sensor I 51 on the Weighing module I 5 is installed in wheel I 3 inboards.Weighing module II4 is connected with displacement servo-drive system II 10.It is inboard that laser range sensor II41 on the Weighing module II4 is installed in wheel II2.
Because displacement servo-drive system I11 is identical with the composition of displacement servo-drive system II 10, so explain with displacement servo-drive system I11, displacement servo-drive system I11 is made up of signal input 113, servo-driver 114, reductor 112, motor 111.
Weighing process:
The weighing device that the front and rear wheel of whole bogie is corresponding in weighing process carries out simultaneously, is changed to example with the refitting of trailing wheel symmetry at present and combines accompanying drawing 1,2,3,4,5,6,7 explanation weighing processes:
1) bogie pushes weighing unit, and wheel rim contacts with the wheel rim rail, and wheel tread and Weighing module are gapped.The wheel rim of wheel II 2 is on wheel rim rail II 14; The wheel rim of wheel I 3 is on wheel rim rail I 13.Start laser range sensor II 41 and laser range sensor I 51 this moment, records the medial surface distance values δ 1 of laser range sensor II 41 and wheel II 2; Record the medial surface distance values δ 2 of laser range sensor I 51 and wheel I 3.
2) calculate the deviate of medial surface distance values δ 1 and δ 2 then respectively according to δ 1 and δ 2 calculating mean values
,
3) deviate
is sent into displacement servo-drive system I11 and displacement servo-drive system II10 respectively.Displacement servo-drive system I11 is identical with displacement servo-drive system II 10 courses of work, is example explanation Weighing module I 5 courses of work with displacement servo-drive system I 11.Displacement servo-drive system I11 starts, deviate
Signal input 113 gets into servo-driver 114, and drive motor 111 rotations drive the ball-screw rotation through reductor 112, on cross track I 9, moves corresponding range deviation value thereby drag Weighing module I 5
Weighing module I 4 moves corresponding range deviation value on cross track I 8
Adjusted distance values this moment δ in theory
1'=δ
2'.
4) start elevator I 52, drag wheel rim rail I 13 and descend, simultaneously, displacement servo-drive system I 11 works in coordination with laser range sensor I 51 and works simultaneously, in real time Weighing module I 5 is done small adjustment, to compensate the error that the degradation factor causes under the wheel rim rail.When Weighing module I 5 contacts with I 3 treads of wheel, the displacement servo-drive system quits work, and wheel I 3 wheel rims are with after wheel rim rail I 13 separates fully, and the measured value of Weighing module I 5 is the wheel load of this wheel I 3.
After Weighing module below each wheel of bogie all passes through above-mentioned adjustment simultaneously, can draw the gross weight of the wheel load and the bogie of bogie.When carrying out duplicate measurements; The Weighing module that bogie pushes below each wheel of back all carries out the adjustment in aforementioned 1-4 step simultaneously; Therefore can eliminate the non-quantitative skew that produces when pushing because of bogie; Make same bogie repeatedly to push the measured value deviation minimum, thereby greatly improved the duplicate measurements precision of measuring system.
