Problems solved by technology

[0005] Aiming at the deficiencies in the use of the existing rail grinding device proposed in the background technology, the present invention provides a rail grinding device that prevents jumping. The advantage of automatic position compensation for stone wear solves the problems in the above-mentioned background technology that the grinding is not complete due to locomotive jumping, and the grinding amount is reduced due to grinding stone wear

Abstract

The invention relates to the technical field of strategic new and emerging industries, and discloses a rail grinding device for preventing jumping, including a transmission body, a symmetrical movable groove I is opened on the center bottom of both sides of the transmission body, and the top of the movable groove I A current layer is provided, and a symmetrical storage slot is provided above the movable slot 1. An elastic rope is movably sleeved in the storage slot, and a fixed plate is fixedly connected to the bottom opening of the storage slot. In the present invention, through the designed current layer, limiting plate, No. 2 electromagnet and driven wheel, after the grinding stone is attached to the surface of the rail under the extrusion of the transmission body, the limiting plate can make the current of the current layer reach the No. 2 electromagnet. Magnets, so that the No. 2 electromagnet absorbs the expansion plate, buckles the expansion plates on both sides and makes the driven wheel touch the bottom end of the rail, so that when the locomotive jumps, the driven wheel can be stuck on the bottom end of the rail, thereby limiting the grinding The bouncing up and down of the stone ensures that the millstone is always attached to the surface of the rail.

Description

technical field [0001] The invention relates to the technical field of strategic emerging industries, in particular to a rail grinding device for preventing jumping. Background technique [0002] Since high-speed railways, high-speed trains, subways and other locomotives are completely guided by the rails, the rails carry huge pressure and impact force from the wheels. Under extremely complex working conditions, various damages will inevitably occur. Including vertical wear, side wear, cracks, fat edges, etc. The existence of these problems will easily increase wheel and rail noise, accelerate the deterioration of vehicle components and track components, and aggravate the further expansion of rail diseases. At this time, it is necessary to grind the rail in advance. , which is actually to cut the surface of the rail, remove the disease, and restore the rail to the best profile. [0003] The existing rail grinding devices are installed on the locomotive in order to improve t...
