Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Along with improving constantly of modern train transport capacity and speed per hour, to traffic safety, steadily and the requirement of ride comfort also increasingly strict.The rail directly contacted with train wheel, its quality directly has influence on safety and the stationarity of driving.By dynamic action, the cause influence such as natural environment and the quality of rail own of train, rail often can damage, as the phenomenon such as crackle, abrasion.
In addition, rail will bear the heavy train of millions of tons every year and to shuttle back and forth in orbit formed immense pressure, and this also easily causes deformation of rail, makes the contact surface distortion of rail and train wheel.Running surface of wheeltrack then may bring negative effect to driving improperly, as consumed fuel more, causing vibrating noise, accelerate wheel wear, increasing maintenance work amount and cost etc., serious even may cause the damage of track and vehicle and the generation of driving accident.Therefore, in time rail failure eliminated or repair very necessary.
Maintenance polishing is carried out to rail, irregularity and the defect of Rail Surface can be eliminated, by tread contour recovery to original design requirement, thus slow down further expanding of surface blemishes, improve traveller's comfort level, reduce wheel track noise.In addition, this maintenance can make rail extend about 50-100% application life.
In addition, relative to replacement track, safeguard that the method for polishing more can the effectively cost-saving and time.Estimate according to Europe staff, up to 1,500,000 dollars, safeguard that the expense of rail grinding is then far below this, this also makes this mode be subject to the attention of railway interests of various countries to the cost (containing artificial and Master Cost) of laying 1 mile of new-track.
Rail maintenance polishing is relatively short in the history of China, and at present, people recognize that the periodic maintenance polishing of rail is for the necessity guaranteeing safety, efficiently locomotive operation further, and take a long view can be more cost-saving in addition.Can predict, steel rail grinding technology will be adopted by high-speed railway, heavy haul railway and urban track traffic more and more, and suitable maintenance polishing is very necessary for guaranteeing that rail is in ideal operation state.
See Fig. 1 to Fig. 7, the vertical sander that the utility model embodiment provides, comprise support 3, power set 2 and grinding wheel 4, also be included in the adjustment of displacement frame of adjustable position on described support 3, described power set 2 are arranged on described adjustment of displacement frame, and described grinding wheel 4 is connected with the output of described power set 2.
The vertical sander that the utility model proposes, its grinding apparatus is except can moving along rail, the position of grinding apparatus can also be adjusted at any time, that is, to in the process of steel rail grinding, can adjust accordingly the position to grinding apparatus according to the actual service condition of rail and problem, thus effectively ensure that the respective handling to rail local location, polishing is settled at one go, does not need to use more equipment to complete the grinding process of different parts.
Further, list in an embodiment of the present utility model, described adjustment of displacement frame is provided with the horizontal feed mechanism 8 that described adjustment of displacement frame can be made to move horizontally on described support 3.
