Weighing, spring regulating and detecting device for bogey of railway locomotive

Abstract

The invention discloses a weighing, spring regulating and detecting device for a bogey of a railway locomotive. The device comprises a hydraulic system and a detection system, wherein in the hydraulic system, a mechanical component is provided with a guide rail, a weighing rail and a load beam, the load beam is arranged above the weighing rail, the guide rail is installed at the front side of the weighing rail, the weighing rail can move up and down under the action of the hydraulic system, and the load beam can move up and down under the action of the hydraulic system and can pressurize the bogey through a hydraulic cylinder installed on the load beam; and the detection system comprises multiple wheel load measuring units, each wheel load measuring unit respectively corresponds to the wheel of the bogey, each wheel load measuring unit is provided with a pressure sensor, the wheel load measuring units are arranged below the weighing rail, and the wheel load measuring units can horizontally move along the direction parallel to the weighing rail under the action of the hydraulic system. In the invention, the whole load pressure is implemented on the bogey after the bogey is assembled, and then wheel load detection is carried out, so as to inhibit the axle load transfer in the running process of the locomotive to the fullest extent.

Description

Technical field [0001] The invention relates to a weighing spring detection device for a railway locomotive bogie. Background technique [0002] With the continuous development of railway transportation in the direction of high speed and heavy load, especially in order to meet the requirements of speed increase, the requirements for the running quality of locomotives are getting higher and higher. As the most important component related to the operation of electric locomotives, the bogie not only supports the entire weight of the locomotive, but also bears a large static load, traction, braking force, and all-directional actions generated by curves, switches, and rail joints during operation. Therefore, it can be seen that the performance and condition of the bogie are directly related to the safety of driving. [0003] At present, in the current inspection process of the weighing and adjusting springs of locomotives, the bogies are not weighed and adjusted, only the weight of the...

AI Technical Summary

Problems solved by technology

Using traditional detection technology and test methods, as well as the locomotive weighing and adjusting spring detection method based on manual experience, is not only inefficient, but also cannot accurately weigh and adjust the locomotive spring detection, which makes the distribution of locomotive axle load uneven and ineffective. Inhibiting the transfer of axle load during locomotive operation will lead to the destruction of locomotive wheel-rail adhesion conditions, limiting the traction, and even threatening driving safety
