Truck carrying saddle binding face stress detection analytical device

Abstract

The invention relates to a device which can intelligently diagnose whether the circular arc surface of a truck carrying saddle and the binding face of a bearing damage the surface of the bearing or not through detecting and analyzing the pressure of the binding face, belonging to the safety detection equipment in the field of railway manufacturing and overhauling. The device comprises a feeding transmission device and a discharging transmission device, a pressure detection cylinder, a pressure actuating rod, a stepping oscillating bar, a detection tyre, a pressure detection support device, a rack and a pressure simulation detection analytical system and the like. The pressure sensor distributed at the contact position of the detection tyre and the carrying saddle can detect stress condition of the carrying saddle; and whether the binding face manufacture of the carrying saddle is qualified or not is judged by accurate analysis.

Description

Technical field [0001] The utility model relates to a device capable of intelligently diagnosing whether the arc surface of a truck saddle and the bonding surface of a bearing have damage to the bearing surface through the detection and analysis of the bonding surface pressure, which belongs to the safety detection equipment in the field of railway manufacturing and maintenance . Background technique [0002] At present, the known bearing saddles of railway freight cars are the supporting components that bear the weight of the entire freight car. Taking a 70-ton truck with a 25-ton axle load as an example, each saddle carries a weight of 12.5 tons. In practice, the direct contact surface with the bearing saddle is the bearing surface at both ends of the wheel. Therefore, if the bonding surface between the bearing saddle and the bearing is not good, or if the pressure transmission is uneven, the bearing will be damaged under the impact of gravity, causing a truck safety accid...

AI Technical Summary

Problems solved by technology

In practice, the direct contact surface with the bearing saddle is the bearing surface at both ends of the wheel. Therefore, if the bonding surface between the bearing saddle and the bearing is not good, or the pressure transmission is uneven, the bearing will be damaged under the impact of gravity, causing a truck safety accident.

However, at present, there is no application and practice of this technology in the field of truck manufacturing at home and abroad. In the existing traditional technology, only the external dimension inspection is carried out before installation, and the fitting surface of the bearing saddle and the bearing cannot be inspected, which has caused Many accidents caused by damage to the bearing due to quality problems in the manufacture of bearing saddles
