Four-angle weighing apparatus for vehicle

Abstract

The invention provides car body four-corner weighing equipment, belonging to the field of weighing technique. The weighing equipment aims at solving the weighing problem and the positioning problem of the gravity center of motor train unit body; the technical proposal is that the car body four-corner weighing equipment consists of two horizontal T-shaped guideways which are arranged in parallel, two supporting crossbeams which are vertical to the T-shaped guideways and four car body weighing units; the T-shaped guideways are pre-embedded in cement ground surface; the upper part of the two ends of the supporting crossbeam is provided with an axial U-shaped sliding trough and the lower part thereof is provided with a connecting plate; the connecting plate is fixed on two T-shaped guideways by a T-shaped bolt; and the four car body weighing units are respectively fixed on the U-shaped sliding troughs which are arranged at two ends of the two supporting crossbeams. The car body four-corner weighing equipment can precisely weigh the weight of various car bodies, can work out the position of the gravity center of the car body according to the measured weight signal and can meet the weighing requirement of various high-speed motor train units.

Description

technical field [0001] The invention relates to a car body weighing device capable of calculating the position of the center of gravity of the car body according to weighing data, and belongs to the technical field of weighing. Background technique [0002] In the past, the speed of domestic trains was mostly below 160KM / H, and the shift of the center of gravity of the car body had little effect on the operation of the train. The method of weighing the car body is generally to use ordinary car body weighing equipment to weigh the front and rear ends of the car body separately. Then add the weights obtained twice to calculate the overall weight of the car body. This weighing method can only weigh the axle load of the train, but not the center of gravity of the car body. But for high-speed EMUs, the running speed can reach more than 300KM / H, the position of the center of gravity of the car body is very important, because in the process of turning, the centrifugal force is prop...

Problems solved by technology

[0002] In the past, the speed of domestic trains was mostly below 160KM / H, and the shift of the center of gravity of the car body had little effect on the operation of the train. The method of weighing the car body is generally to use ordinary car body weighing equipment to weigh the front and rear ends of the car body separately. Then add the weights obtained twice to calculate the overall weight of the car body. This weighing method can only measure the axle load of the train, but cannot calculate the center of gravity of the car body.

But for high-speed EMUs, the running speed can reach more than 300KM / H, the position of the center of gravity of the car body is very important, because in the process of turning, the centrifugal force is proportional to the square of the speed, and a small center of gravity offset will produce a huge Centrifugal force may push the train out of the track, causing a vicious accident of car crash
