Description

A kind of the laser automatic rust removing device and derusting method of igneous rock cracks
Technical field
The present invention relates to away rust by laser technical field, laser automatic rust removing device and the derusting of a kind of igneous rock cracks are referred in particular to Method.
Background technique
With being continuously increased for Chinese high-speed rail operating mileage, car speed is getting faster, and is required traffic safety also more next Higher, this, in maintenance craft, proposes very high requirement, mesh to flaw detection to the wheel of bogie of car part in railway wheel Before, most of vehicle wheels boil the method washed and manually derusted to use buck, the disadvantage is that labor intensity of workers is big, inefficiency, Activity duration influence long and to the pollution of environment and to rail man's health etc. is and novel there is many shortcomings Advanced passenger train has largely used rubber parts, and the aging washed and can be accelerated into rubber parts is boiled using buck, reduces its performance, the total vehicle of iron Easy to use, the high-efficient wheel of one kind is badly in need of to derusting cleaning equipment in maintenance department.
Laser removing rust is exactly that the principle of laser cleaning is:The light beam of laser transmitting need to handle the pollution layer institute on surface It absorbs, the absorption of the big energy of pollution layer forms the plasma sharply expanded, then generates shock wave, shock wave becomes pollutant It fragmentates and is removed, but must according to circumstances adjust laser parameter, the energy density of light pulse is made strictly to be in two thresholds It is the automatic control of cleaning by the important results that two threshold values generate between value, energy density is higher than the light arteries and veins of first threshold Punching will reject always pollutant, until reaching base material, for railway wheel to derusting mode and mechanism, by adjusting swashing Power, the energy of light device, according to the complexity of rusty scale or particle, the simple area for adjusting hot spot has quilt to make to export laser Identical energy density, theoretical and derusting cleaning ability, in R&D process, sometimes for laser to be transported to specified derusting Laser beam is transmitted using optical fiber in position, and advantage of this is that applied widely, flexible to operation, the hot spots of output Energy distribution is also relatively uniform, and disadvantage can exactly lose some energy, particularly evident when transmission range is longer, does so Meanwhile the mode of output facula is not sufficiently stable sometimes, in addition, we also use light-conducting arm to carry out transmitting beam, mainly by lens It is conducted with reflecting mirror, maintains the shape of light beam to the maximum extent in this way.
In conjunction with the more mature away rust by laser principle of the prior art, it is now desired to which one kind can be exclusively used in igneous rock cracks and remove Rust operates more convenient and fast laser rust-removing device, and the shape and material for igneous rock cracks carry out more suitable cleaning, can The wheel pair of corresponding different model carries out the ability of corresponding more automatic rust-removing, and there is presently no the devices of professional cleaning wheel pair.
Based on this, the present invention devises the laser automatic rust removing device and derusting method of a kind of igneous rock cracks, on solving State problem.
Summary of the invention
The purpose of the present invention is to provide the laser automatic rust removing devices and derusting method of a kind of igneous rock cracks, on solving The igneous rock cracks that can be directed to different model proposed in background technique are stated, different information matches are carried out, and are carried out automatic Operation is specially skillful in the derusting problem of wheel pair.
The invention is realized in this way:A kind of laser automatic rust removing device of igneous rock cracks, including laser cleaning device, ranging Instrument and hand-held laser spray gun, the laser cleaning device and hand-held laser spray gun are electrically connected, and are installed on the hand-held laser spray gun The rangefinder, manual switch is provided on the handle of the hand-held laser spray gun, and laser automatic rust removing device further includes support Plate, vertical telescopic rod and controller, the controller is installed on the laser cleaning device, and the support plate passes through support leg and ground Support is stablized in face, and the vertical telescopic rod is erected at the top of support plate, and horizontal extension is installed on the top of the vertical telescopic rod Bar, the outer end mounting fixing parts of the horizontal extension bar, the hand-held laser spray gun are connect with fixing piece, described vertical flexible Bar, horizontal extension bar and hand-held laser spray gun are electrically connected with controller.
