Abstract

The utility model discloses a rail turnout grinder which is characterized in that a group of runners are arranged around the center bore of a little vehicle; an inner rolling cycle and runners matching with each other are fixed on the little vehicle; an inner rolling cycle seat with a vertical plate is fixed in the inner rolling cycle. The two sides of a main frame are provided with support shafts, the main frame and the vertical plate on the inner rolling cycle seat have a rolling fit. A worm wheel is fixed on the support shaft of the frame and a worm is fixed on the inner rolling cycle seat. The utility model can turn the grinding head to grind the other rail, omitting the trouble of carrying and lifting the little vehicle in addition to grinding by the outer margin of the grinding wheel. The utility model has the advantages of high precision of grinding, flexible and convenient installation, transportation and operation and is a novel rail turnout grinding device with distinctive features.

Description

Rail track switch sander

Technical field:

The utility model relates to a kind of sander, more particularly relates to rail track switch sander, belongs to a kind of improvement of fuel oil rail track switch sander.

Background technology:

As everyone knows, in railway transportation,, the wearing and tearing and the plastic strain of rail rail level have been caused because the wheel of vehicle and locomotive rolls at a high speed repeatedly for a long time to rail, also can irregular overlap, particularly track switch appear in the inboard of rail's end portion simultaneously and the bend highway section particularly serious.The overlap of rail had both quickened the wearing and tearing of wheel, had reduced the application life of wheel again, had also increased the idle energy consumption of the hauling capacity of a locomotive simultaneously.Therefore, the overlap that rail is rolled out will in time keep in repair polishing, is used for improving the driving quality of railway transportation.Existing rail track switch sander is made of cart, dolly, main frame, working machine and engine five parts usually, this sander exists following some deficiency: the overlap that the bistrique (emery wheel) on (1) working machine can only grinding one side rail, if mill opposite side rail then will lift dolly (together with working machine, engine, main frame etc.) from cart, put back to again behind the rotation 180 degree angles and reset grinding on the cart, like this, both increase labour intensity, reduced production efficiency again; (2) the bistrique gyratory directions is parallel with rail, like this, can only utilize the side grinding overlap of emery wheel, and this grinding method is comparatively suitable for the straight way rail, and has not just adapted to especially for track switch and bend, as particularly inconvenient with the bigger emery wheel work of diameter; (3) all to adopt friction-type to finish fixing vertically rotate adjustment along the rail face for the work bistrique (emery wheel) of existing sander, and its stability then is difficult to control with accuracy; (4) big bassinet structure is a monolithic, and length reaches about 2.5m, and is bulky, heavy, has all brought inconvenience for packing, transportation and operation.

Summary of the invention:

The purpose of this utility model provides a kind of rail track switch sander, it can not only overcome above-mentioned deficiency, and working machine is forwarded to carry out grinding on another track, flexible operation, angle are arbitrarily adjustable, also can utilize the grinding of emery wheel outer rim simultaneously, cart can decompose, installation, convenient transportation.

The purpose of this utility model is to realize like this, it includes cart, dolly, the main frame of working machine is housed, it is characterized in that being provided with one group of runner around the dolly centre bore, rolling ring cooperates with runner in rotating, in interior rolling ring, be fixed with the inner rolling ring seat of band riser, between inner rolling ring seat and little car bottom plate locking device be housed; The both sides of main frame are provided with back shaft, and main frame cooperates with riser shaft on the inner rolling ring seat by back shaft; Worm gear is fixed on the back shaft of main frame, and the worm screw that cooperates with worm gear is fixed on the riser of inner rolling ring seat.

The utility model has the advantages that, since on dolly, be equipped with rotating in rolling ring, the work function is freely rotated by interior rolling ring, bistrique grinding opposite side rail on the rotation work machine easily, saved the trouble of lift to move dolly, not only can use the then face of emery wheel to carry out grinding, but also the outer rim of available emery wheel is carried out grinding; Owing on main frame back shaft and inner rolling ring seat, increased worm mechanism, improved the grinding accuracy of working machine greatly again; Simultaneously, at the two ends of cart bar dismountable cart wheel set being installed, making that cart is installed, transportation and operation be more flexible, is a kind of novelty and the rail track switch grinding apparatus that shows unique characteristics.

Fig. 1 is a concrete structure schematic diagram of the present utility model.

Fig. 2 is main frame insight structural map.

Fig. 3 is the dolly constructional drawing.

Fig. 4 is the upward view of Fig. 3.

The specific embodiment:

In Fig. 1-4, runner 16 is the flute profile wheel, and four runners 16 evenly distribute by wheel carrier 17 usefulness screws and are fixed on dolly 5 centre bores 18 base plate 4 all around.Interior rolling ring 10 has the outer rim that cooperates with runner 16 races, mouth in being provided with in the interior rolling ring 10, and interior rolling ring 10 places by outer rim in the notch of four runners 16, is rotatably assorted with runner 16.The middle part of inner rolling ring seat 13 has a square hole by working machine bistrique 9, and bistrique 9 is a kind of emery wheels.On inner rolling ring seat 13, be welded with two risers 14, on riser 14, axle sleeve be housed, in inner rolling ring seat 13 is sat and is placed rolling ring 10 in mouthful on be screwed.Locking device is that the positioning tooth 11 that cooperatively interacts and 19, two positioning tooths 11 of limiting tooth are screwed centre bore 18 both sides at dolly base plate 4 symmetrically.Limiting tooth 19 is the arc tooth, and limiting tooth 19 is screwed on inner rolling ring seat 13, is used for cooperating with positioning tooth 11 rolling ring 10 in the locking.Working machine is contained on the main frame 1, is fixed with back shaft 15 on main frame 1, and main frame 1 is connected with 14 of risers on the inner rolling ring seat 13 by back shaft 15, and main frame 1 can rotate according to back shaft 15, be used for adjusting working machine bistrique 9 and inner rolling ring seat 13 between and also.Dismountable big wheel assembly 6 is arranged on the bar 8 of cart, the jack of wheel set 6 is arranged on the end face at cart bar 8 two ends, cart wheel set 6 is pegged graft with the jack of bar 8 terminations, and is fixing with lock-screw 7 at last.

During work, behind the intact side rail of grinding, withdraw from pin 12 and shift out positioning tooth 11, rolling ring 10 state that unlocks makes main frame 1 rotate 180 degree angles by interior rolling ring 10 and runner 16 again in making, and uses positioning tooth 11 operating angles more again.Worm gear 3 is screwed on the back shaft 15 on the main frame 1, and the worm screw 2 that cooperates with worm gear 3 is fixed on the riser 14 on the inner rolling ring seat 13.Rolling ring 10 in the locking, insertion pin 12 just can carry out the grinding to another rail; When making main frame 1 rotate an angle of 90 degrees by interior rolling ring 10, the outer rim of available bistrique 9 is carried out the grinding to rail.When grinding is carried out at the angle on carrying out the rail inboard, rotate and make worm screw 2, drive and to carry out the rail grinding after the main frame 1 of worm gear 3 rotations is transferred to corresponding position with bistrique 9.
