Device and method for assembling and disassembling axle box nodes

Abstract

The invention discloses a device for assembling and disassembling axle box nodes, which comprises a pull rod, a base plate, angle iron, a pulling plate, a supporting plate, a hydraulic jack, a double-screw bolt, a press plate and a baffle plate, wherein the base plate is provided with a round hole; the base plate, the pulling plate, the press plate and the supporting plate respectively pass through the pull rod; the base plate and the puling plate are fixedly connected through the angle iron; the hydraulic jack is arranged on the supporting plate; the double-screw bolt passes through the pulling plate and the press plate and then is locked and fixed with the press plate by a clamping nut; the baffle plate is fixed on the outer lateral surface of the pulling plate; and an extrusion device for extruding the axle box nodes is arranged between the hydraulic jack and the press plate. During the disassembly of the axle box nodes, the device does not need to build up a precise bearing workshop, purchase precise equipment for checking and cleaning bearings and purchase special hydraulic equipment and grease injecting equipment, only needs the investment of 10,000RMB and saves the land of 500m<2> as well as the investment of 3.85million RMB for factory building and equipment; the whole set of device can be in threaded connection, can be convenient to disassemble and assemble as well ascarry; and in addition, a peripheral power source is not needed to use and the requirement on clean degree of the working environment is not strict.

Description

technical field [0001] The invention relates to a device and method for installing and dismounting an axle box node. Background technique [0002] The railway passenger car bogie needs to replace the worn axle box nodes during use. The method is to disassemble the wheel set → open the special sealed axle box cover → remove the axle box and bearings from the wheel set in turn → use special hydraulic equipment to disassemble the old axle Box joints → Install new axle box joints using special hydraulic equipment → Inspect and clean bearings using special equipment in a sophisticated bearing assembly workshop → Install bearings and axle boxes into wheel sets in sequence → Refill grease → Install axle boxes Cover and seal. This method has cumbersome procedures, takes a long time, requires supporting special equipment and a special site, and requires a large investment, which cannot meet the needs of maintenance under relatively harsh natural environmental conditions at the use s...
