Abstract
The invention relates to a grinding machine for a weld joint in the rail flange of a steel rail. The grinding machine aims to grind the surface of the weld joint of the steel rail smooth and prolong the service life of the rail. The grinding machine comprises a support frame formed by a top plate, a baseplate and front and rear side plates. Notches are formed in the top left corners of the front and rear side plates of the support frame, a lifting frame is arranged in the support frame, a sliding plate capable of sliding left and right is arranged in the lifting frame, the sliding plate is provided with a grinding wheel on the left side of the top and a motor and an armrest on the right side of the top from inside to outside, and a belt transmission mechanism is arranged between the grinding wheel and the motor.
Description
Technical field
The present invention relates to a kind of rail grinding machine, particularly a kind of rail flange of rail machine for grinding welding seam.
Background technology
The development of current China city railway constantly strides forward to high speedization, track seamless process, and track welding is then a most important technology, and the quality of rail joint is also the key having influence on circuit work-ing life and train operation.
Rail joint welding quality except refer to weld seam inherent welding quality, if inside is with or without welding flaw etc.; Also comprising the surface quality of rail joint weld seam, such as the polishing quality of rail joint weld seam, the unfairness on surface will directly affect travelling speed and the stationarity of train, and thus causes additional impact load etc. And the surface quality of the rail flange of rail, due in use train by time the flange of rail be the position by maximum tension stress effect, the stress raisers that surface irregularity causes, can shorten the fatigue lifetime of rail greatly. But it is when on-the-spot steel rail welding line polishing operation, particularly when integral cement railway roadbed, owing to the space between the rail flange of rail and railway roadbed is relatively little, more difficult when the weld grinding of the rail flange of rail is constructed.
Summary of the invention
The present invention is to solve above-mentioned existing problem, it is provided that a kind of steel rail welding line surface finish is smooth, it is to increase the rail flange of rail machine for grinding welding seam in track life-span.
A kind of rail flange of rail machine for grinding welding seam, comprise the bracing frame being 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 raising legs, raising legs inside be provided with can left and right slide slide plate, 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 transmission mechanism between described emery wheel and motor.
Support frame as described above top board is provided with threaded hole, on raising legs top board, corresponding bracing frame threaded hole place is provided with through hole, this sander is also provided with lifting rod, described lifting rod is arranged in the threaded hole of bracing frame top board by screw thread and passes the through hole of raising legs, and described lifting rod bottom is provided with back-up ring and is limited on lifting rod by raising legs.
Before and after described raising legs, both sides are installed with sliding cover respectively, are provided with two sliding bars between support frame as described above top board and base plate, and described sliding cover is set on corresponding sliding bar.
Before and after described slide plate, both sides are respectively equipped with roller, and are arranged in the slideway of raising legs by slide plate by roller.
The invention has the beneficial effects as follows:
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, facilitates grinding process.
2, slide plate be contained in the slideway of raising legs and can left and right slip, can be polished in each position of weld seam by emery wheel, and roller make that slide plate slides in slideway lighter.
3, promote emery wheel by raising legs, make emery wheel promote polishing welding seams, thus reach the effect of smooth welded seam.
