Description
Technical field
The present invention relates to a kind of rail milling vehicle grinding attachments, belong to technical field of mechanical manufacturing equipment.
Background technology
By nearly development in twenties years, the production domesticization of China's steel rail grinding equipment achieves certain achievement, but whole
Technical merit is compared still with developed country larger gap, and rail milling vehicle is public by the Linsinger companies of Austria and MFL
Department is monopolized, and import is completely dependent on, and becomes the huge obstacle of China's maintenance of way development.With the fast development of China railways,
Demand of the country to rail milling vehicle is increasing, and it is very urgent to develop the milling vehicle with China's independent intellectual property right thus.
Grinding attachment is one of the main working parts of rail milling vehicle, is ground to Rail Surface after milling attachment milling, mill
The grinding quality of turning device directly determines that rail is finally polished effect.
Rail milling vehicle carries out reparation polishing mainly for the larger track of abrasion deformation, respectively has two sets of millings in rail both sides
The workpiece of turning device and a set of grinding attachment as milling vehicle.Using peripheral milling technology, the milling disk in milling attachment is all
To installation milling cutter knife grain, every 8 knife grains constitute one and cut milling unit, and one of knife grain is used for milling gauge angle, makes gauge angle
Place is round and smooth curved surface, remaining knife grain is used for rail surface milling, a total of 22 milling units.
Vehicle carries out milling by milling attachment first, and the key wear surplus of track is removed, due to by mill circumferential direction
The limitation of installation space, grinding cutter grain number mesh are restricted, and circumferential milling cutter is only possible to provide a small amount of number on track longitudinal direction
Purpose knife grain carries out milling, therefore will produce a large amount of milling lapping defects in raceway surface, and train will produce larger when running at high speed
Noise, grinding attachment is exactly the grinding rail after milling, by a grinding wheel disposable grinding rail rail head region, to obtain
Good rail shape and rail level quality.
On the rail of grinding attachment work in the wild, preceding working procedure is milling, and live dust is more, while the work of milling vehicle
All weather operations as environment, may meet be exposed to the sun, drench with rain, the operating conditions such as ice and snow, high temperature low temperature, to have waterproof and dustproof,
High-low temperature resistant characteristic.It is completed in a short time the reparation of track section, does not allow to break down in the course of work, but works and completes
Afterwards, repair inspection the time it is more sufficient, therefore it is required that the functional reliability of grinding attachment will be got well.
Transverse shifting and the vertical feed movement of grinding spindle system are the key that realize grinding operation, two grinding attachments
Mobile can should individually control also want coordinated signals.In standby mode, two grinding attachments lift, and are leaned on to centre
Hold together, grinding wheel is detached with rail, and needs machine security locking, does not influence walking of the milling vehicle on rail；In Job readiness
When, abrasive grinding wheel is placed on rail rail level by the movement in the two directions so that grinding wheel is contacted with rail, is ready for
Grinding；When being ground operation, when laterally having vibration or the operation on bend, need, to grinding attachment laterally positioning in real time, to make
It obtains grinding wheel and is pressed in rail center always, grinding length feed speed is determined by vehicle to run, constant magnitude, vertical feed
Movement needs to control the size of stock removal, can eliminate the interference of extraneous various factors so that grinding is uniform, meets steel rail grinding
Requirement.
The vertical feed of grinding attachment is one of the key technology for realizing rail grinding.Entire grinding attachment catenary motion is wanted
The function of realization has：It is moved downward before grinding and grinding wheel is pressed onto on rail, the speed of decline is adjustable；It can adapt to when grinding outer
Boundary's environmental change compensates the abrasion of grinding wheel, adjusts grinding depth in real time so that grinding hooks；It can in the case where encountering emergency
Fast lifting；Extreme higher position is maintained at when not operation, grinding wheel is not contacted with rail.
Invention content
Present invention mainly solves the technical issues of：It is engaged for unfavorable grinding is generated in existing grinding attachment grinding process
Angle causes grinding to generate the heat of bigger, is overheated so as to cause rail, or even the problem of burning black phenomenon occurs, and the present invention provides
A kind of rail milling vehicle grinding attachment.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：

It is provided with upright slide rail, is provided with vertical running gear on upright slide rail, connection framework below vertical running gear is set on frame
It is equipped with motor, sharpener is provided with below frame, is provided with positioning boots on the left of sharpener, the sharpener is pacified by connecting plate
On frame, connecting plate both sides are connected by hydraulic telescopic device with movable plate, movable plate connection driven wheel, in connecting plate
Between be connected with driving wheel by mainboard, be provided with frosted tape on driving wheel and driven wheel.
A kind of application process of rail milling vehicle grinding attachment is：Grinding attachment is mounted on rail milling vehicle by pedestal
On, rail milling vehicle needs to be ground rail after carrying out milling to rail, and positioning boots determine rail when being ground operation
Position makes sharpener move to above rail by longitudinal running gear, and vertical running gear, which moves downward, makes sharpener close to steel
Track surface, sharpener push movable plate to move downward close to hydraulic telescopic device elongation after Rail Surface, and movable plate drives driven
Wheel moves downward, and the frosted tape on sharpener is made to be close to Rail Surface, and then driving wheel rotation drives frosted tape movement, to right
Rail Surface is ground.
The sharpener is provided with two groups.
The motor is servo motor, and is provided with two groups.
The beneficial effects of the invention are as follows：
A kind of belt grinding attachment is devised in the present invention, belt grinding attachment includes frame, and motor, frame are provided on frame
Lower section is provided with sharpener, and positioning boots are provided on the left of sharpener, and the sharpener is mounted on by connecting plate on frame, even
Fishplate bar both sides are connected by hydraulic telescopic device with movable plate, and movable plate connects driven wheel, among connecting plate by mainboard with
Driving wheel is connected, and frosted tape is provided on driving wheel and driven wheel, and device passes through hydraulic telescopic device promotion activity when working
Plate moves downward, and movable plate drives driven wheel to move downward, to make frosted tape close to Rail Surface, then the rotation that passes through driving wheel
Turn to drive frosted tape movement to be ground rail, it is unfavorable to effectively prevent generating in grinding process in this way
It is ground engagement angle, grinding is caused to generate the heat of bigger, is overheated so as to cause rail, or even occurs burning black phenomenon, and is used
Frosted tape grinding can make Rail Surface grinding uniform, effectively improve the quality of rail grinding.
