Railway full-automatic bearing press

Abstract

A railway full-automatic bearing press comprises a base, a left side frame, a right side frame, a pull rod, a left-right main pressed combination oil cylinder, a bearing bracket, a hydraulic and electric control system; the left side frame and the right side frame are connected with two sides of the base; the top parts of the left side frame and the right side frame are connected by the round pullrod so that the whole set of device form a closed frame force-bearing structure; the left-right main pressed combination oil cylinder is symmetrically equipped to both ends of the base; the middle part of the base is equipped with a wheel-pair intelligent whole supporting, locking and thrusting wheel system which is provided with an upper platform; the lower part of the platform is equipped withan intelligent supporting lifting mechanism; the locking devices are respectively symmetrically equipped to the inner side of the guide rail above the upper platform; the thrusting wheel and the oil cylinder device are respectively symmetrically equipped into the openings above the left guide rail and the right guide rail; lifting guiding mechanisms which are composed of the guiding blocks fixed to the base are equipped to the right side and the right side of the upper platform; laser sensors are equipped to the left main oil cylinder base and the right main oil cylinder base; and the measuring device is equipped to the base. According to the invention, all railway wheel-pair bearings can be pressed without oil-cylinder supporting wheel pair and the operation is simple and reliable.

Description

technical field [0001] The present invention relates to railway special mechanical equipment, which is suitable for EMUs with different gauges such as domestic, foreign, standard gauge, wide gauge, urban rail transit (subway, light rail), passenger cars with 2 to 3 brake discs, ordinary freight cars, Assembly, pressure inspection or extrusion test of rolling bearings for locomotives, tugboat wheelsets and European standard wheelsets. Background technique [0002] With the introduction and localization of EMUs with a speed of about 350km / h, as well as the development of domestic subways and urban rail transit, the design of wheel sets has been continuously updated, and there are various types of domestic and foreign wheel sets. The bearing press-fitting of railway locomotives is basically manual operation, and the way of manual assembly is far from meeting the technological progress of railway vehicles and the speed-up of trains. Not only is the efficiency low, but also the a...

Problems solved by technology

For this reason, aiming at the structure with a brake disc or a chassis in the middle of the wheel set of the EMU, which cannot be balanced and lifted in the middle of the wheel shaft, I have researched and developed and applied for the patent of "Bearing Pressing Machine for EMUs (2009200836450)" to solve the problem This problem has been solved, but it is still not ideal. In order to meet the actual needs, there must be advanced and reliable bearing press-fitting machines to meet the press-fitting of different types of bearings during the maintenance and manufacture of various wheelsets, improve the press-fitting efficiency, and ensure that all Press-fit bearings meet different standard requirements
