Problems solved by technology

[0003] The correction of this kind of process is backward, time-consuming and laborious, and the side beam will be heated and corrected, which will result in a decrease in the strength of the side beam, thereby greatly reducing its service life
It will take a long time and cost a lot if the deformed side beam rail vehicle is shipped back to the original manufacturer for correction
At present, there is a cold correction process realized by pulling and pressing. This process is usually controlled based on the experience of the operator, and the displacement and strength of the correction cannot be accurately controlled. Problems such as over-calibration and redundant correction often occur

Abstract

The invention discloses a railway vehicle side beam detection and self-adaption correction device. The railway vehicle side beam detection and self-adaption correction device comprises a fundamental component (2). An upper jacking mechanism, a lower pulling mechanism and a control mechanism are arranged between the fundamental component (2) and a side beam (9). The upper jacking mechanism comprises a component cross beam (7) and a hydraulic jack (6). The lower pulling mechanism comprises a combined cross beam (4) and an adjustable pull rod (3). The control mechanism comprises a measurement ruler (5) and a control cabinet (10). The invention further discloses a railway vehicle side beam detection and self-adaption correction method. According to the railway vehicle side beam detection and self-adaption correction device, the hydraulic jack conducts jacking, and meanwhile, and the combined cross beam generates counteractive pull force, so that deformation correction of the side beam is realized; the measurement ruler measures the deformation degree of the side beam in real time and transmits a feedback signal to the control cabinet; jacking force of the hydraulic jack is controlled through the control cabinet to realize self-adaption correction of upwarp and downwarp deformation of the front end of the side beam.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle repair machinery and equipment, and more particularly relates to a rail vehicle side beam detection and self-adaptive correction device and method. Background technique [0002] At present, there is no suitable method for correcting the deformation of side beams in the field of rail vehicle maintenance. The traditional process uses thermal correction, that is, heating the deformed side beams and then correcting the side beams whose hardness has decreased. [0003] The correction of this kind of process is originally backward, time-consuming and laborious, and the heating and correction of the side beam will result in a decrease in the strength of the side beam, thereby greatly reducing its service life. If the deformed side beam rail vehicle is shipped back to the original manufacturer for correction, it will take a long time and the cost will be extremely high. At present, there is a cold ...
