A vibration damping rubber pad is arranged between the railpad type sensor and a steel rail, the railpad type sensor locates between the steel rail and an installation pedestal, and a steel platform is equipped below the installation pedestal. The utility model solves the problem of complex installation of combined type and inserted type rail weighbridges, the effective weighing area is extended, the requirements of different types of trains are met, bringing great convenience to maintenance and installation by users; besides, the running security is improved, the measuring accuracy is enhanced, becoming more stable, safer and more reliable.
Description
Technical field
The utility model relates to a kind of continuous rail track scale, and relating in particular to a kind of rail cushion does not have the continuous rail track scale of foundation ditch, belongs to the measuring weighing instrument technical field.
Background technology
Track scale (weigh bridge) is that the length with a joint track for a train compartment is the load-supporting part of measuring weighing instrument, and the measuring weighing instrument that is connected or is connected with the mechanical proportional lever with electronic sensor.
Existing track scale mainly contains combined type and filling type, and these two kinds all will be used the filling type sensor, continuous speed-raising along with railway locomotive, measurement requirement improves constantly, need to solve: how effectively to regulate the weighing section length according to different automobile types and wheelbase, improve sensor stability, improve the dynamic weighing data accuracy; How to improve the continuous rail track scale of no foundation ditch and use the simplification of installing, security.
Existing combined type and filling type do not have the continuous rail track scale of foundation ditch, the sensor that being applied in combined type does not have in the continuous rail track scale of foundation ditch is rail cushion sensor and filling type sensor, the sensor that filling type does not have in the continuous rail track scale of foundation ditch is a filling type, and this class formation weighing precision is low, poor stability, maintenance big, have problem such as security hidden danger, causes the track scale can't normally permanently effective use; Can't effectively regulate the weighing section length according to different automobile types and wheelbase, improve sensor stability, improve the dynamic weighing data accuracy.The filling type sensor is because of punching on rail when mounted, and the processing request of this sensor mounting hole is strict, increased the complexity when installing, answer the continuous speed-raising of railway locomotive simultaneously, on rail, beaten the hole after all, not only influenced the precision of measuring, also there is certain unsafe factor in stability.
The utility model content
The utility model provides a kind of rail cushion not have the continuous rail track scale of foundation ditch, with the weak point in solving the problems of the technologies described above.
For solving above technical matters, the technical solution adopted in the utility model is: a kind of rail cushion does not have the continuous rail track scale of foundation ditch, comprises rail cushion sensor, is provided with the vibration damping rubber cushion between described rail cushion sensor and the rail; Rail cushion sensor is between rail and mounting seat, and there is steel platform the below of mounting seat.
The utility model has solved combined type and the filling type track scale is installed complicated problems, expanded effective weighing district, realized the requirement that vehicle differs, user's maintenance and installation are brought great convenience, improved traveling security simultaneously, improved measuring accuracy, stable more, safety, reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a mounting structure synoptic diagram of the present utility model.
Fig. 2 is continuous rail track combination sensing weighing device structural drawing
Embodiment
As shown in Figure 1, the utility model comprises rail cushion sensor 1, rail 2, damping rubber cushion 3, steel platform 4, mounting seat 5, rail fastening 6.Be provided with the vibration damping rubber cushion between the flange of rail of rail cushion sensor 1 and rail 2, the rail in weighing district and outside rail can be connected or weld with fish platee, can effectively reduce vibration, improve measuring accuracy; Rail cushion sensor 1 is between rail 2 and mounting seat 5, and steel platform is positioned at the below of mounting seat 5.The installation method of the rail cushion sensor 1 that the utility model adopts is directly some rail cushion sensors 1 to be installed between the rail 2 by mounting seat 5, and then the whole piece rail is fixed on the sensor, this installation can be according to actual needs, increase and decrease the quantity of rail cushion sensor easily, can realize prolonging expansion or reduce effective weighing district.
The utility model is used to be mainly used in the weight metering of haulage vehicles such as all kinds of lorries that travel on railway and the industrial and mining enterprises' track and tank car.Weighing precision reaches 0.3%FS, environment for use temperature-45 ℃～130 ℃.
Adopt the continuous rail combined type of no foundation ditch weighing device, form by 64 rail rail cushion sensors, symmetry is installed on two rail of railway, this device not only has safe and reliable, the characteristics such as construction is simple, no foundation ditch and continuous rail of rail cushion sensor, but also " full floating " weighing district that can form.The length in its weighing district can be expanded with the increase of rail cushion number of sensors, and weighing-up wave is no longer lost.Its weighing structure can satisfy the application conditions of all kinds of heavy rails, metering performance and traditional have the foundation ditch track scale equally matched, and performance ratios such as stability, accuracy and serviceable life have the foundation ditch Weighing system more superior.Constantly rail track combination sensing weighing device structural drawing as shown in Figure 2.
This track scale is directly some rail cushion sensors to be installed in all kinds of shaped steel plane, concrete ground beam pre-buried steel backing plate, steel framework platform (rigid frame scale body) on by mounting seat rail cushion sensor, again the whole piece rail is fixed on the sensor by Ministry of Railways's standard method, can spread the vibration damping rubber cushion between the sensor and the rail flange of rail for reducing vibration, the rail in weighing district and outside rail can be connected with fish platee or weld by Ministry of Railways's standard method.Can form a weighing-up wave induction zone, when external force (wheel wheel load) affacts on each sensor by rail, form the stressed weighing-rail of many fulcrums, sensor just produces an output signal that is directly proportional with external force.Can increase and decrease the quantity of rail cushion sensor easily according to actual needs, just can realize prolonging expansion or reduce effective weighing district.When wheel along rail when Weighing Area moves, can measure electric signal on each rail cushion sensor, owing to do not have other bypass influence in the Weighing Area, thereby make weighing-rail form " full floating " weighing structure, after technical finesse, obtain the signal that is directly proportional with weight.
Range ability of the present utility model is: 10t～80t; And to have maximum range be 200t sensor-specific checkout equipment, and the outgoing that can satisfy far away the wide range sensor detects.
Rail cushion sensor adopts extra-thin plank frame, and when external force affacts on the sensor by rail, sensor just produces an output signal that is directly proportional with external force.Can increase and decrease the quantity of rail cushion sensor according to actual needs easily, just can realize prolonging expansion or reduce effective weighing district.
Rail cushion sensor technology parameter: linear error :≤0.05%FS; Reproducibility error :≤0.05%FS; Hysteresis error :≤0.05%FS; Insulation resistance 〉=5000M Ω; Output sensitivity S=1.0～2.0mV/V is optional; Zero temperature influence :≤0.05%FS/10 ℃; The environment for use temperature :-40 ℃～+ 80 ℃ and-30 ℃～+ 120 ℃ and-10 ℃～+ 130 ℃ are optional.Relative humidity≤95%; The IP68 level of protection; Overload capacity is 125%; Shock resistance life-span 〉=5,000,000 times.The utility model has improved stability, the accuracy of metering aspect, has increased the serviceable life of weighing system greatly.
