Embodiment
With reference to Figure of description, the utility model is described in more detail.
As shown in Fig. 2 to Fig. 3, according to the device of the present utility model for railway freight-car check weighing, with single-unit lorry car
Railway carriage or compartment 30 is unit, the method for realizing check weighing, sets 4 sensor supports 10 in rail cars bottom and is respectively arranged in biography
The laser range sensor 20 of sensor support member 10；Sensor support 10 includes sensor support bar mobile jib portion 11, passes through weldering
Connect or the laser range sensor fixed part 12 for being installed on the one end of sensor support bar mobile jib portion 11 is fixed or be integrally formed to bolt
And the ground vertical calibration mechanism 13 of the other end of sensor support bar mobile jib portion 11 is installed on, ground vertical calibration mechanism 13 passes through
The edges and corners for the front and back of boxcar 30 that projecting or attracting mode is fixed on directly over rail 40.
Sensor support bar mobile jib portion 11 is Collapsible structure, and the self friction power in sensor support bar mobile jib portion 11 can
Keep stretching structure part and the position of laser range sensor 20 stable.
In above-mentioned, the Collapsible structure in sensor support bar mobile jib portion 11 can be the hydraulically extensible side of piston and cylinder body
Formula, or the mechanical retractable mode between some sleeve pipes.
Laser range sensor 20 is bolted or inserted mode and is installed on laser range sensor fixed part 12,
And the laser head vertical irradiation of laser range sensor 20, directly over rail 40, the installation site of laser range sensor 20 should
It is defined by rail 40 when the zero load of boxcar 30 or maximum allowable load in the effective range of laser range sensor 20, this
Place's design can effectively protect laser range sensor 20 so that situation of the laser range sensor 20 in the normal ranging work of energy
Under, it can also protect laser range sensor 20.
As shown in fig. 1, in the present embodiment, sensor is fitted with respectively in the edges and corners of bottom four of boxcar 30
Support member 10 and laser range sensor 20, method for measuring weight is as follows：
First, 4 laser range sensors 20 implement ranging first before the loading of boxcar 30, in boxcar 30
After loading, 4 laser range sensors 20 implement second of ranging；Then, by 4 rangings twice of laser range sensor 20
Displacement variable is converted into weight；Finally, calculated through equalising torque, draw the weight of the loading of single-unit boxcar 30.
After railway freight-car load-carrying, it can cause the pendulum spring of load-bearing on train vehicle frame that mechanical deformation, the upper table of rail 40 occurs
Face can change relative to the height of laser range sensor 20, according to Hooke's law, in elastic limit, single-unit lorry car
The weightening of railway carriage or compartment 30 is directly proportional to vertical direction spring deformation amount, after each point laser range sensor 20 captures displacement variable,
By the inversion cuver of calibrated distance and weight, weight amount is obtained, then is calculated through equalising torque, finally draws single-unit goods
The weight of the loading of car compartment 30.
Increase weight computational methods for single-unit boxcar 30, the point offset variable hi after the zero load of measurement boxcar 30 and load-carrying,
Measurement point vertical direction coefficient of elasticity ki, measurement point support force Fi=ki*ki, increase goods gravityThen according to torque
Equilibrium condition can obtain equation：[Z]=[A] * [F], loading gross weight and center of gravity of goods position can be calculated：
Wherein：
Pass through above-mentioned formula, you can obtain loading gross weight.
Device provided by the utility model for railway freight-car check weighing, its advantage are：
1st, weight of object data can be quickly obtained, speed is fast, and precision is high；
2nd, automaticity is high, only need to be to being counted respectively once before and after the loading of goods train carriage 30, you can easily draw
Result of calculation；
3rd, only need to be above rail 40,4 laser range sensors of front and rear sides adhesive of boxcar 30 can be quick
The loading capacity of railway freight-car is calculated, therefore the utility model cost is cheap.
Ranging check weighing is carried out using 4 laser range sensors 20 in the present embodiment, more laser can also be passed through
