Description

Technical Field

[0001] The utility model relates to the field of dynamic curved track weighing pad weighing sensors, in particular to a multi-vector curved steel rail weighing pad weighing sensor module component. Background Art

[0002] Dynamic track scales are widely used in national railways and high-speed railways, as well as in railway dedicated lines of large, medium and extra-large industrial and mining enterprises such as steel, metallurgy, coking, petrochemical, energy, thermal power generation, cement and building materials, machinery manufacturing, mining, airports, ports, docks, logistics yards, transfer stations, etc., because they can realize continuous dynamic measurement of each vehicle of freight trains, passenger trains and special railway trains in the process of movement, uniform speed passage, fast measurement speed, accurate measurement, safety and reliability. They can dynamically measure the loaded materials of various rail vehicles and various special rail vehicles, accurately formulate raw materials for large-scale continuous production within working conditions enterprises, and improve the refined measurement of the quality of basic industry products, playing an important role.

[0003] However, in the prior art, most track scales use column pressure sensors. The outer rail is higher than the inner rail at the bend, and the vehicle being weighed is tilted in the direction of the curvature radius. Since the weighing sensor only uses a column pressure weighing sensor structure, the specific gravity of the items loaded on the vehicle is different, and the center of gravity height is different; in addition, there is a lack of horizontal force measurement sensors for the centrifugal force and centripetal force of vehicles on curves. The vertical force sensor alone cannot detect the errors caused by the actual acceleration, centrifugal force and centripetal force when the vehicle turns; furthermore, the column pressure sensor installed at the curve position, when installed in a sloped position on the curve, is affected by the lateral force, which greatly reduces the technical indicators of the sensor itself, such as linearity, hysteresis, and repeatability. In addition, the previous curved track scales are of the broken rail type, which poses a greater safety hazard to vehicles traveling in the curved area. Therefore, a multi-vector curved rail pad weighing sensor module assembly is proposed. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is: in the prior art, most track scales adopt column pressure sensors, the outer rail is higher than the inner rail at the bend, and the weighed vehicle is inclined in the direction of the curvature radius. Since the weighing sensor only adopts a column pressure weighing sensor structure, the specific gravity of the items loaded on the vehicle is different, and the center of gravity height is different; in addition, there is a lack of horizontal force measurement sensors for the centrifugal force and centripetal force of the vehicle on the curve, and the vertical force sensor alone cannot detect the errors caused by the actual acceleration, centrifugal force and centripetal force when the vehicle turns; furthermore, the column pressure sensor installed at the curve position, when installed in a position with a slope on the curve, is affected by the lateral force, which greatly reduces the technical indicators of the sensor itself, such as linearity, hysteresis, repeatability, etc., and the previous curved track scale is a broken rail form, which poses a greater safety hazard to vehicles traveling in the curved area.

Example

[0055] Please refer to Figure 1-23 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that this embodiment provides a multi-vector curved rail pad weighing sensor module assembly, specifically.

[0056] The multi-vector curved rail pad weighing sensor module I is evenly distributed in a fan shape at a certain interval along the length of the rail. The multi-vector curved rail pad weighing sensor components are arranged at a spacing of 1760 sets / km, and the signals of sensors 1#-N# with horizontal force detection function in the N multi-vector curved rail pad weighing sensor modules 1 are respectively connected to the data acquisition interfaces corresponding to the horizontal force detection; along the length of the rail, it is evenly distributed in a fan shape at a certain interval, which conforms to the mechanical principle of multiple fulcrums.

Example

[0059] Please refer to Figure 1 , Figure 4 and Figure 7 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that this embodiment provides a multi-vector curved rail pad weighing sensor module assembly, specifically.

[0060] The bottom of the rail arc slot on the elastic body of the multi-vector curved rail pad weighing sensor body 1 is designed with a 1:40 slope consistent with the requirements of the Ministry of Railways, which not only meets the railway engineering specifications, but also plays the role of installing shock-absorbing rubber pads for buffering and shock reduction. Example

[0061] Please refer to Figure 1 , Figure 4 and Figure 5 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that this embodiment provides a multi-vector curved rail pad weighing sensor module assembly, specifically.

[0062] The rail slots and male and female arc-shaped insulating pads 10 on the elastic body of the multi-vector curved rail pad weighing sensor body 1 adopt arc slots and arc-shaped insulating pads under the curved spring bars that match the curvature radius of the curved bend area and the size of the rails used on the line, which control and fix the rail gauge in the curved area, ensure safe driving under dynamic conditions, and facilitate the stable positioning of the rails in the curved area. They not only ensure the positioning of the rails at the curved bends, but also ensure that the horizontal force can be accurately transmitted to the sensor through the circular arc contact, so that the original horizontal force and vertical force obtained by the sensor are very real, which is conducive to the overall improvement of the measurement performance of the novel continuous track dynamic curved track scale, and ensures the track insulation and driving safety of the curved bends. Example

[0063] Please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.12This embodiment is based on the previous embodiment, and is different from the previous embodiment in that this embodiment provides a multi-vector curved rail pad weighing sensor module, specifically.

[0064] The multi-vector curved rail pad weighing sensor body 1 has a vertical force signal output interface and a horizontal force signal output interface. The output mutation or abnormal signal of the multi-vector curved rail pad weighing sensor body 1 provides accurate and scientific original data for the expanded application of vehicle safety warning functions such as impact caused by wheel tread, wheel flat scar and missing corner of railway freight trains, EMU marshaling, high-speed rail marshaling and special railway vehicles in the process of movement. Example

[0065] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Fig.11 and Fig.13 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that this embodiment provides a multi-vector curved rail pad weighing sensor module assembly, specifically.

[0066] The horizontal force sensor comprises a second resistance strain gauge R1, R2, R5, R6, R9, R10, R13, R14, and compensation resistors Rto, Rct / 2, Rc / 2, Ri, Rz, Ui, Uo, Rw1, which are connected to a sensor wiring board (17) and a Wheatstone bridge circuit. R1, R6, R10, and R13 in the Wheatstone bridge circuit are pull-type pieces; R2, R5, R9, and R14 are press-type pieces; Rto is a temperature zero point compensation resistor; Rct is an elastic modulus compensation resistor; Rc is a sensitivity coefficient compensation resistor; and Ri is an input resistance consistency. Compensation; Rz: zero point compensation resistor; Rw1 is the compensation resistor against vertical force interference; Ui is the DC bridge voltage; Uo is the voltage signal output. The process of a vehicle moving on a straight track is actually a serpentine motion trajectory; the process of a vehicle moving on a curved line is affected by the high center of gravity of the loaded goods and the "semi-circular" or "S" curve shape of the low curve; through the horizontal force sensor, the magnitude of the derailment coefficient caused by the centrifugal force and centripetal force of the vehicle in the curved area is continuously collected, judged, calculated, and compensated in real time;

[0067] In the circuit of the multi-vector curved rail pad weighing sensor body 1, since the output signal of the vertical force is much larger than the output signal of the horizontal force, an Rw1 vertical force interference compensation resistor and a horizontal force interference compensation circuit are designed. Therefore, sensors of different vectors on the same elastic body perform their respective functions and do not interfere with each other, ensuring the accuracy and reliability of data collection such as the original nonlinearity, repeatability, and lag of the horizontal force, so that when the vehicle is in the curved bend area, the computer can make real-time and accurate judgment and compensation for the real errors introduced into the system by the centripetal force and centrifugal force, which is beneficial to improving the reliability, stability and accuracy of the sensor output signal.

[0068] When Uo outputs a "positive signal", it is under positive force, and when Uo outputs a "negative signal", it is under reverse force; the multi-vector curved rail pad weighing sensor body 1 can know in real time whether the vehicle is in a curved area through the size of the horizontal force output signal. Due to the errors caused by the centrifugal force and centripetal force generated by the vehicle, when the horizontal force sensor outputs a "positive signal", it is the positive force value caused by the centrifugal force of the vehicle; when the horizontal force sensor outputs a "negative signal", it is the negative force value caused by the centripetal force of the vehicle. Through real-time acquisition of the horizontal force signal, the size of the positive and negative signals are compared by computer analysis. The computer can make a correction and compensation decision in real time according to the mathematical model of the dynamic track scale, which plays an extremely important role in the technical improvement and technological innovation of the dynamic curved track scale. The horizontal force sensor of the multi-vector curved rail pad weighing sensor body 1 judges the centrifugal force and centripetal force relative to the sensor by outputting a "positive" signal or a "negative" signal, which is more beneficial to reducing the complexity of electrical design, debugging, and maintenance, and reducing manufacturing costs.

[0071] Working principle: When a vehicle passes through the measuring section of the multi-vector curved rail pad weighing sensor assembly, the vehicle applies a vertical force Fy to the slope sensor, where m is the mass and g is the acceleration of gravity. is the centrifugal force of the vehicle, the radius of the arc of the rail at the curve is R, the speed of the locomotive or car is v, and due to the need for centripetal force, there is an inclination angle α between the outer rail and the inner rail foundation in the curve area of ​​the two rails at the curve. When the locomotive passes through the curve track scale, the multi-vector curve rail pad weighing sensor body 1 of the curve track scale is subjected to a vertical force Fy and a horizontal force Fx relative to the sensor direction, where , , solving the above two formulas can get , since α≤1, therefore;
