[embodiment]
The present invention is further described in conjunction with accompanying drawing.
Referring to Fig. 1 to Fig. 6, Fig. 1 to Fig. 6 shows one embodiment of the present invention, is the half of one kind " double rail type "
Automatic rail grinding machine, can polish two rail side by side simultaneously；If mainly include rail fixed platform, translation platform and dry rubbing group
Part.The present embodiment is used on the building site of railway engineering site operation use, its rail that correction of the flank shape object is 60Kg levels of polishing.
Wherein, rail fixed platform sets up and is horizontally fixed on two side by side on rail, horizontally movable translation platform
Connected by sliding equipment with rail fixed platform；It is provided between rail fixed platform and translation plates and is used to realize translation platform
The sliding equipment moved horizontally.
Referring to Fig. 4, rail fixed platform described in the rail fixed platform includes substrate, the shifting fixed by horizontal rotating shaft
Dynamic roller, waist locating piece, lower clamping cylinder and lift cylinder, wherein, shifting roller carries out upper and lower fortune by lift cylinder driving
Dynamic, the top connecting substrate of shifting roller, shifting roller and rail head of rail are in contact；The lower surface of the substrate is separately connected with down
Clamping cylinder, the lower clamping cylinder are located at the outside of steel rail web, and the lower clamping cylinder is horizontally arranged and described
Lower clamping cylinder drives the waist locating piece for clamping steel rail web.
Referring to Fig. 5, some rail head locating pieces are connected with below the substrate, the lower section of the rail head locating piece is set respectively
Have with rail head of rail shape corresponding to groove, the groove is placed on rail head of rail.
Referring to Fig. 3, the translation platform includes translation plates, and the translation plates are located at the lower section of rail fixed platform.Institute
State slide rail, the sliding block that four compositions pair are provided between translation plates and rail fixed platform.Slide rail, sliding block limit for additional translational plate
In the enterprising line slip in rail longitudinal axis direction, and helpful substrate recommends the function of translation plates.
Referring to Fig. 2, the sliding equipment is included in slip servomotor set by substrate center, screw mandrel and in translation plates
The sliding sleeve fixed.Corresponding device is respectively equipped with the middle position of substrate and translation plates, i.e., centre is provided with insertion base in a substrate
The sliding groove of plate, through the sliding groove and screw mandrel is penetrated in the sets of holes of the sliding sleeve of translation plates upper surface, the screw mandrel is sliding
Moving horizontally for translation plates is realized under servomotor driving.Slip servomotor is started, screw mandrel drives the fortune of sliding sleeve by screw thread
It is dynamic；Because sliding sleeve connects with translation plates, and then drive the connection of translation plates.
Left and right two groups of sanding components are provided with the translation platform, two groups of sanding components correspond to two simultaneously respectively
Arrange rail.The sanding component of the present embodiment is five tools, and the grinding head of five tool sanding components uses the forming grinding wheel of CBN materials, its
Moulding, the square left side side for corresponding to rail head of rail respectively, the right side side of rail head of rail, steel rail web and the rail flange of rail at two.
The position of corresponding two one steel rails is respectively equipped with the opening of arranged on left and right sides, the polishing of the five tools sanding component on substrate, translation plates
Some to be polished rail levels of the head through opening difference " dislocation alignment " two one steel rails.
Referring to Fig. 1 and Fig. 2, " dislocation alignment ", accurately for be exactly by five grinding heads for having sanding components (i.e.
The forming grinding wheel of CBN materials) it is respectively aligned to the rail head of rail in the projection along on rail axis direction, the web of the rail and the flange of rail at two
Treat burnishing part.The reason for being arranged such be, the grinding heads of five sanding components is if placed in approximately the same plane, due to size
Reason can produce it is overlapped and the problem of can not work, so being set in translation plates along rail direction every a small distance
Put a sanding component, i.e., so-called " dislocation "；But if by the projection of this five grinding heads be placed on one it is coplanar upper when, beat
Mill region is precisely cross sectional shape that rail treats burnishing part, i.e., so-called " alignment ".
Thus the five tool sanding components of alignment of misplacing can divide into upper right, bottom right, upper left, lower-left and the polishing of bottom five
Component.The sanding component includes grinding head, variable-frequency motor, transmission belt；Variable-frequency motor drives grinding head by pulley belt
Rotate (the present embodiment uses belt transmission)；The rear end of sanding component is provided with the servomotor for urging it into operating position and pushed away
Motivation structure.
Referring to Fig. 6, especially it is noted that the sanding component for rail flange of rail polishing is located at the side side of rail
To the height of its grinding head is consistent with rail flange of rail face and is connected with the cylinder that horizontal direction promotes to the rail flange of rail.It is other
Upper right, bottom right, upper left and the sanding component of lower-left can be shifted to install flexibly as required.
Equipment is pushed into the weld of rail by the present embodiment first when in use, carries out positioning action afterwards：Utilize substrate
The rail head locating piece of groove is separately fixed on two one steel rails corresponding to four bands and rail head of rail shape on four angles, then
Whether check and correction is horizontal.After confirming substrate, translation plates for level, eight lower clamping cylinders of the both sides of steel rail web are controlled to push away
