Problems solved by technology

However, in the field of locomotive maintenance, the design of the locomotive weighing device at this stage is too complicated, the volume is large, and the measurement accuracy is also low. The adjustment of the wheelbase requires a large wrench to adjust the large nut in the center of the device, and the technical work is intensive. Therefore, there is an urgent need to design a subway vehicle weighing device that can reduce the labor intensity of the staff, is applicable to different gauges, and has high measurement accuracy.

Abstract

The invention provides a portable subway vehicle weighing device which includes a screw adjusting unit, support platforms, and sensors. The two ends of the screw adjusting unit are fixedly connected with the two support platforms. The screw adjusting unit can drive the support platforms to move to the two ends or to the middle. The sensors are fixedly arranged inside the support platforms. The beneficial effects are as follows: the portable subway vehicle weighing device is simple, small and light; the position of the device can be adjusted at any time in a simpler and more labor-saving manner, and thus, the device can adapt to various subway vehicles with different wheel bases and lengths between truck centers; and a single wheel is weighed using multiple sensors, and the weighing range and weighing efficiency of the weighing device are improved.

Description

technical field [0001] The invention belongs to the field of measurement, and in particular relates to a portable metro vehicle weighing device. Background technique [0002] In recent years, the rail transit industry has developed rapidly, and urban underground rails have been widely popularized across the country, which has provided great convenience for people's travel and life, and has also driven the economic development of related places. However, in the field of locomotive maintenance, the design of the locomotive weighing device at this stage is too complicated, the volume is large, and the measurement accuracy is also low. The adjustment of the wheelbase requires a large wrench to adjust the large nut in the center of the device, and the technical work is intensive. Therefore, there is an urgent need to design a subway vehicle weighing device that can reduce the labor intensity of the staff, is applicable to different gauges, and has high measurement accuracy.
