Locomotive oil tank edge correcting device

Abstract

The invention discloses a locomotive oil tank edge correcting device which comprises a supporting rod, a fixing base, a jack, a jack fixing device, a supporting rod quick-changing device and a movablefixing base. The fixing base is fixedly installed at one end of the supporting rod, the other end of the supporting rod is connected with the jack fixing device, and the jack is fixedly installed inthe jack fixing device. According to the designed fixed base and movable fixed base structure, an ejector rod device can be quickly fixed to the box edge and automatically generate a standard warmingarea; for an oil tank with small size difference in two directions of the tank edge, the inward bending correction of the tank edge can be realized by utilizing the telescopic change of the jack headwithout replacing the support rod. For an oil tank with large size difference in two directions of the tank edge, a supporting rod quick-changing device can be used for replacing a supporting rod witha matched size to correct the inward bending of the tank edge; the jack fixing device ensures that the jack does not fall off in the continuous force application process, and is safe and reliable; and the jack fixing device is designed to be of a detachable structure, and the jack can be conveniently detached, maintained and replaced.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and processing, and in particular relates to a tank edge correction device for a locomotive fuel tank. Background technique [0002] The main transformer oil tanks of locomotives are box-type welded structural parts with open tops. The large welding deformation caused by the welding of the fuel tank edge and the fuel tank cylinder will cause serious concave bending deformation of the fuel tank edge. Therefore, after the welding of the fuel tank of the general locomotive main transformer is completed, the deformation along the fuel tank needs to be corrected to meet the technical requirements of the drawings and product performance requirements. Due to the large deformation of the fuel tank along the welding, flame correction alone cannot straighten the deformation of the fuel tank along the welding, and the correction efficiency is low. Using special straightening machinery requir...

AI Technical Summary

Problems solved by technology

Due to the large deformation along the welding of the fuel tank, flame correction alone cannot straighten the deformation along the welding of the fuel tank, and the correction efficiency is low. It requires a large investment to use special straightening machinery and equipment, and a special production site is required, and the production capacity is limited by the number of straightening equipment.
