Abstract
The utility model belongs to a dynamic electronic rail balance. The utility model is characterized in that a rail is a succession rail, measure bridges are fixed on the lower part of the rail, an anti-torsion rod is arranged between the left measure bridge and the right measure bridge, a gravity sensor is arranged on the both ends of each of the measure bridges, the gravity sensor is arranged on a base, the base is a whole, the both end parts of which are fixed on the rail through shim plate screw bolts, a shearing force sensor is arranged on an erect face of the rail between the measure bridges and a steel tie, and the shearing force sensor and the gravity sensor are communicated with a signal acquisition processor. The rigidity of the rail balance is large, not only upper and lower vibration and deformation can be prevented, but also left and right torsion and spread can be prevented, and the utility model has the advantages of strong integrity, even stress of the gravity sensor, long service life, and high measuring precision.
Description
The utility model relates to track scale, is a kind of dynamic electronic rail balance.
At present, the track scale of domestic production has two classes, and a class is " a disconnected rail track scale ", adopts gravity sensor merely, deserve to be called rail and normal orbit and disconnect, and keep gap, this track scale poor stability, it is slow that train up and down has impact shock, train to cross weighing apparatus speed during weighting platform, and weighing error is big; Another kind of is " constantly rail track scale ", is made up of rail, weighting platform, gravity sensor, shear force sensor, pedestal and signal acquisition process device.The rail span is big on this track scale weighting platform, easy vibration deformation up and down, about easily twist, open, cross the weighing apparatus train and be prone to derailment accident, weighing error is big.
The purpose of this utility model provides a kind of dynamic electronic rail balance, adopts gravity sensor merely to solve " disconnected rail track scale ", and weighting platform poor stability, train have the vibration of dashing during weighting platform up and down, and weighing error is big; The rail span is big on " constantly rail track scale " weighting platform, easy vibration deformation up and down, about easily twist, open, cross the weighing apparatus train and be prone to derailment accident, the big problem of weighing error.
The purpose of this utility model is achieved in that this dynamic electronic rail balance is by rail, shear force sensor, gravity sensor, base constitutes, rail is continuous rail, the intrinsic survey bridge of difference below the rail of the measuring section left and right sides, about survey between bridge and be provided with anti-torsion bar, the survey bridge is provided with gravity sensor below the two ends, it is fixed on the base, on the steel sleeper of base both ends by the intrinsic backing plate of bolt, backing plate is by bolt, pressing plate is fixed on the rail, be provided with shear force sensor on the rail facade between survey bridge and steel sleeper, shear force sensor is connected the signal acquisition process device with gravity sensor.
The base both ends are provided with 2-3 root steel sleeper respectively, are connected as a single entity by web joint, and there is left and right sides groove at the middle part, are to be made of side plate and base plate, and its shape size matches with surveying bridge, and left and right sides groove is divided into three sections with the middle part steel sleeper, is one by bolt or solid welding.
The signal acquisition process device is to pass through A/D converter by amplifier, and parallel interface is communicated with computing machine and stabilized voltage supply is formed.
This utility model compared with prior art has the following advantages: (1) is surveyed bridge and is fixed together with rail, about survey between bridge and be provided with anti-torsion bar, both strengthened rail rigidity, prevent the up-down vibration distortion, can prevent from again to twist about rail, open; (2) base is to constitute one by steel sleeper, connecting plate and base plate, is connected as a single entity with rail again during use, and globality is strong, and base is not yielding, gravity sensor is stressed evenly, long service life, measuring accuracy height.
Be described further below in conjunction with accompanying drawing:
Fig. 1, dynamic electronic rail balance structural representation;
Fig. 2, dynamic electronic rail balance A-A cut-open view;
Fig. 3, dynamic electronic rail balance electrical schematic diagram.
Among Fig. 1-3: shear force sensor 1 has four, adopt axial pin type sensor, steel sleeper 2 adopts shaped steel or steel plate to make, connecting plate 3 adopts steel plate or shaped steel to make, rail 4 is the conventional continuous rail of laying, and surveys bridge 5 and adopts steel plates and shaped steel to make, about having two, it is by bolt, pressing plate is separately fixed on the rail of the left and right sides, survey 5 on bridge two and be provided with anti-torsion bar 9, be equipped with gravity sensing 7 below surveying bridge 5 two ends, gravity sensor adopts vertical sensor, it is fixedly mounted on the base 6, base 6 both ends are provided with steel sleeper 2 respectively, are connected as a single entity by connecting plate 3, and there is left and right sides groove at the middle part, groove is to be made of side plate and base plate 10, and its shape size matches with survey bridge 5.Left and right sides groove is divided into three sections with the middle part steel sleeper, leans on bolt or solid welding together.
During use, base 6 buries seat on stone, and both ends steel sleeper 2 is bolted together with backing plate 8, and backing plate 8 pressured crab bolts are fixed on the rail 4.The signal that shear force sensor 1 and gravity sensor 7 are gathered is sent into signal acquisition process device 11, amplifies through amplifier 12 to enter A/D converter 13, and parallel interface 14 is communicated with computing machine 15, stabilized voltage supply 16 power supplies.
