Abstract
The utility model relates to a kind of railway freight-car weighing monitoring structure, comprising: railway freight-car; For carrying the pendulum spring of railway freight-car; The axle box assembly be fixedly connected with described pendulum spring; Be installed on the wheel on described axle box assembly; The bottom of described pendulum spring is connected with LOAD CELLS, and LOAD CELLS is connected with the weighing instrument be arranged on railway freight-car, then weight signal is converted to electrical signal transfer to weighing instrument by LOAD CELLS, realizes the monitoring of railway freight-car.In the utility model, LOAD CELLS is electronic equipment, need not connect pneumatic brake pipe, simplify pipe system, and decreases the leakage hidden danger point of air pipe line, improves vehicle reliability.Meanwhile, the Realtime Alerts of vehicle weight and unbalance loading rate is achieved when or else this programme can change railway freight-car structure.
Description
Technical field
The utility model relates to rolling stock field, specifically, relates to the sub-weighing device of a kind of railway wagon.
Background technology
The existing railway freight-car of China, by across arranging contact transducer valve above beam or arranging weighing valve in single stage suspension position, realizes the damping force adjustment of empty and load.Contact transducer valve utilizes bogie camber of spring indirectly to weigh, and thus low, the poor stability of its weighing precision, is applicable to slow running, the railway freight-car lower to braking distance requirement
Existing weighing device can meet the empty and load adjustment requirement of domestic existing railway freight-car substantially, but when train speed grade reaches 160km/h and be above, the sensitivity of existing weighing device, precision then show slightly not enough.In addition, High-Speed Freight Vehicle is particularly responsive to vehicle unbalance-loading, thus, High-Speed Freight Vehicle to weigh with car and unbalance loading calculate export propose new requirement.
Therefore, how improving the load carrier of existing railway freight-car, is the problem that those skilled in the art's letter need solve.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of railway freight-car weighing monitoring structure.This programme by improving existing rolling stock, when making railway rolling stock weight or unbalance loading rate more than a threshold value, warning device alarm.
In order to reach above-mentioned purpose, the utility model adopts following technical scheme:
A kind of railway freight-car weighing monitoring structure, comprising:
Railway freight-car;
For carrying the pendulum spring of railway freight-car;
The axle box assembly be fixedly connected with described pendulum spring;
Be installed on the wheel on described axle box assembly;
The bottom of described pendulum spring is connected with LOAD CELLS, and LOAD CELLS is connected with the weighing instrument be arranged on railway freight-car, then weight signal is converted to electrical signal transfer to weighing instrument by LOAD CELLS, realizes the monitoring of railway freight-car.
The beneficial effects of the utility model are:
One, immediately export weight and the unbalance loading rate of vehicle with car, the alarm that transfinites is pointed out, and is convenient to car operation management and improves traffic safety;
Two, directly weigh, ensure weighing precision; Electric signal transmission, effectively shortens signal transmission time, ensures the sensitivity of empty and load damping force adjustment;
Three, LOAD CELLS is electronic equipment, need not connect pneumatic brake pipe, simplify pipe system, and decreases the leakage hidden danger point of air pipe line, improves vehicle reliability;
Four, LOAD CELLS is relative to air shut-off valve, and compact conformation, volume are little, and the space being beneficial to bogie is arranged;
Accompanying drawing illustrates:
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, pendulum spring, 2, LOAD CELLS, 3, axle box assembly, 4, wheel, 5, railway freight-car.
Embodiment:
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1: a kind of railway freight-car weighing monitoring structure, comprising:
Railway freight-car 5;
For carrying the pendulum spring 1 of railway freight-car 5;
The axle box assembly 3 be fixedly connected with described pendulum spring 1;
Be installed on the wheel 4 on described axle box assembly 3;
The bottom of described pendulum spring 1 is connected with LOAD CELLS 2, LOAD CELLS 2 is connected with the weighing instrument (not shown) be arranged on railway freight-car 5, then weight signal is converted to electrical signal transfer to weighing instrument by LOAD CELLS 2, realizes the monitoring of railway freight-car.
In use, this programme can export weight and the unbalance loading rate of vehicle immediately with car, the alarm that transfinites is pointed out, be convenient to car operation management and improve traffic safety, simultaneously, LOAD CELLS 2 is electric signal transmission, effectively shortens signal transmission time, ensures the sensitivity of empty and load damping force adjustment.
LOAD CELLS 2 is electronic equipment, need not connect pneumatic brake pipe, simplify pipe system, and decreases the leakage hidden danger point of air pipe line, improves vehicle reliability.
After have employed said structure, when or else this programme can change railway freight-car structure, achieve the Realtime Alerts of vehicle weight and unbalance loading rate.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
