Description
Technical field
The utility model relates to a kind of rail grinding machine, particularly machine for grinding welding seam at the bottom of a kind of Rail.
Background technology
The development of current China city railway constantly strides forward to high speed, track seamless process, and track welding is then a vital technology, and the quality of rail joint is also the key having influence on circuit application life and train operation.
The quality of bond weld except referring to the inherent welding quality of weld seam, if inside is with or without weld defect etc.; Also comprise the surface quality of rail joint weld seam, as the polishing quality of rail joint weld seam, the out-of-flatness on surface directly will affect the speed of service and the stationarity of train, and causes additional impact load etc. thus.And the surface quality at the bottom of Rail, due in use train by time the flange of rail be position by maximum tension stress effect, the stress raisers that surface irregularity causes, can shorten the fatigue life of rail greatly.But it is at the scene during steel rail welding line polishing operation, particularly when integral cement railway roadbed, because the space at the bottom of Rail and between railway roadbed is relatively little, more difficult when the weld grinding at the bottom of Rail is constructed.
Summary of the invention
The utility model is to solve above-mentioned existing issue, provides a kind of steel rail welding line surface finish smooth, improves machine for grinding welding seam at the bottom of the Rail of orbital lifetime.
Machine for grinding welding seam at the bottom of a kind of Rail, comprise the bracing frame be made up of top board, base plate and front and back side plate, its special character is: before and after bracing frame, the upper left corner of side plate is provided with gap, bracing frame inside is provided with hoisting frame, hoisting frame inside is provided with the slide plate that can horizontally slip, described slide plate top left side is provided with emery wheel, right side and is provided with motor and handrail from the inside to the outside, is provided with belt gear between described emery wheel and motor.
Support frame as described above top board is provided with screwed hole, on hoisting frame top board, corresponding bracing frame screwed hole place is provided with through hole, this sander is also provided with lifting arm, described lifting arm is arranged on the through hole also through hoisting frame in the screwed hole of bracing frame top board by screw thread, and described lifting arm bottom is provided with back-up ring and is limited on lifting arm by hoisting frame.
Before and after described hoisting frame, both sides are installed with sliding sleeve respectively, are provided with two slide bars between support frame as described above top board and base plate, and described sliding sleeve is set on corresponding slide bar.
Before and after described slide plate, both sides are respectively equipped with roller, and are arranged in the slideway of hoisting frame by slide plate by roller.
The beneficial effects of the utility model are:
1, before and after this bracing frame, the left end of side plate is provided with gap, is lifted by rail and is placed on it, facilitate grinding process.
2, slide plate be contained in hoisting frame slideway in and can horizontally slip, polished in each position of emery wheel energy butt welded seam, and roller slide plate is slided in slideway lighter.
3, promote emery wheel by hoisting frame, make emery wheel promote polishing welding seams, thus reach the effect of smooth welded seam.
