The technical solution provided by the present invention is explained in more detail below with reference to fig. 1 to 5.
As shown in fig. 1, when a rail grinding device used in the prior art works, a cup grinding manner is adopted to grind a rail. When the cup-shaped grinding device works, the steel rail grinding is carried out through the end face in the axial direction of the cup-shaped grinding device, the limitation is caused by the working principle, the profile repaired by the cup-shaped grinding vehicle is formed by enveloping a plurality of tangent planes, the arc transition is lacked, and the edge angle exists on the surface formed after cutting, so that the profile of the steel rail at the grinding opening is not smooth, and the stress concentration after repairing is easily caused; meanwhile, the cup-shaped grinding adopts end face cutting, and the cutting performance of the end face is poor, so that the efficiency of cutting and grinding the steel rail is low.
Based on the above problems, the polishing efficiency of the polishing device needs to be effectively improved, so that the steel rail can be polished more flexibly and efficiently.
Example 1:
according to the grinding device for the steel rail, the traditional cup-shaped grinding device is adjusted to be the tangent plane grinding device, the steel rail is efficiently ground by utilizing the grinding stone with higher cutting efficiency at one time, and the full coverage and larger cutting amount of the section of the steel rail are realized by using less grinding stones.
As shown in fig. 2, the present invention provides a grinding apparatus for a steel rail, the apparatus including a base 1 and a grinding unit; wherein, a positioning unit 2 which can be attached to the steel rail for positioning and a grinding unit for cutting the steel rail are arranged on the base 1. The grinding unit comprises a grinding stone assembly 3 and a beveling mechanism 4; the beveling mechanism 4 comprises a rotating component 41 fixedly connected with the grinding stone assembly 3, and the grinding stone assembly 3 can be driven by the rotating component 41 to rotate along the circumferential direction so as to adjust and change the longitudinal matching angle of the grinding stone 31 and the steel rail.
Above-mentioned positioning element 2 adopts guide arm or circular guide plate structure, can hug closely the rail inboard during the operation, for the sideslip provides benchmark and spacing to the adjustment unit of polishing is in on suitable operating position.
When the inclined cutting mechanism 4 works, the grinding stone assembly 3 can rotate relative to the steel rail so as to adjust the angle between the grinding stone assembly and the steel rail, and the adjustment of a cutting point and a cutting area is realized; in addition, the grinding wheel assembly 3 can grind the rail by the tangent plane of the tangent line, as shown in fig. 3. The grinding efficiency is improved by utilizing the self-sharpening property of the grinding stone 31, and an arc line matched with the profile of the steel rail is formed on the cutting surface, so that the surface of the cut steel rail is smooth and has no edge angle, and the problem of stress concentration on the surface of the steel rail is effectively avoided.
In order to ensure that the beveling mechanism 4 can be used better, the rotating assembly 41 is configured as a disk structure which can be driven to rotate, and the disk structure can be driven to rotate by the worm gear driving structure 42; or the disc structure can also be driven by one of an electric cylinder, a hydraulic oil cylinder and a hydraulic air cylinder to rotate; alternatively, the disk structure can be rotated by the worm gear drive 42, and the worm gear drive 42 can be driven by any one of an electric cylinder, a hydraulic cylinder, and a hydraulic cylinder. When the rotating component 41 rotates, the grinding stone assembly 3 can rotate along the circumferential direction along with the rotation of the rotating component 41, so that the longitudinal matching angle of the grinding stone 31 and the steel rail is changed, and as shown in fig. 6, the grinding stone 31 can rotate in the plane of the XY axes.
Because the size of different rail is different, can help grindstone assembly 3 to carry out accurate location all the time in order to guarantee positioning unit 2, need adjust positioning unit 2's position: as an alternative embodiment, the device also comprises a traverse unit 5 fixedly connected with the positioning unit 2, and the traverse unit 5 can be used for adjusting the distance between the grinding stone assembly 3 and the steel rail by pushing the positioning unit 2 to move transversely relative to the steel rail. Relative lateral movement in the X-axis direction can be generated between the grindstone assembly 3 and the positioning unit 2 at this time with reference to the coordinate axes.
Specifically, the traverse unit 5 includes a guide plate 51 and a traverse driving member 52, the guide plate 51 has a guide groove capable of guiding the positioning unit 2 to move laterally and defining the lateral movement range of the positioning unit 2, and the traverse driving member 52 is capable of pushing the positioning unit 2 to move laterally along the guide groove relative to the rail.
When the traversing unit 5 works, the position of the positioning unit 2 can be conveniently and flexibly adjusted. Under the premise that the position of the grinding stone assembly 3 relative to the base 1 is not changed, the transverse adjustment of the position of the transverse moving unit 5 is equivalent to the transverse adjustment of the distance between the grinding stone assembly 3 and the steel rail, and the equipment can be adapted to tracks of different specifications.
Generally, the guide groove may be a strip-shaped hole structure or a similar guide groove structure.
The traverse drive 52 may be an automatic assembly controlled by an electric control or other device, or may be a manual assembly controlled manually: specifically, when the traverse driving member 52 is an automatic assembly (i.e., the telescopic member 521), at least one of an electric cylinder, an air cylinder and a hydraulic cylinder may be used, the fixed end of the telescopic member 521 is fixedly connected to the base 1, and the movable end is fixedly connected to the positioning unit 2. When the telescopic member 521 is started, the movable end of the telescopic member works to drive the positioning unit 2 to move transversely along the guide groove so as to adjust the position of the positioning unit 2. When the traverse driving member 52 is a manual component (i.e., the traverse bolt 523), a traverse adjusting seat 522 with an internal thread is fixedly mounted on the base 1, one end of the traverse bolt 523 abuts against the positioning unit 2, and the other end is connected with the traverse adjusting seat 522 in a threaded manner. The traverse bolt 523 is rotated to adjust the relative positional relationship between the traverse bolt 523 and the traverse adjustment seat 522.
The traverse bolt 523 and the traverse adjusting seat 522 may be independently installed to be used as a conventional adjusting mechanism; alternatively, the traverse bolt 523 and the traverse adjustment seat 522 may be provided together with the expansion piece 521: when the expansion member 521 is out of order, the traverse bolt 523 and the traverse adjustment stand 522 may be temporarily used. By taking the positioning unit 2 as a reference, automatic or manual accurate adjustment of the traverse amount can be conveniently realized through an electric cylinder, a hydraulic cylinder or a traverse bolt 523.
As an optional embodiment, the device further comprises a deflection unit 6 fixedly connected with the grinding unit, wherein the deflection unit 6 can be used in cooperation with the traverse unit 5 to adjust the contact position of the grinding stone 31 and the section of the steel rail, so that the steel rail can be cut at a specific angle, and the ground profile can meet the design requirement.

As the deflecting frame 61 rotates relative to the deflecting guide plate 62, the grinding unit can be synchronously deflected by the deflecting guide plate 62, and the grinding stone 31 can be rotated in the plane of the XZ axis by the deflecting unit 6 with reference to the above coordinate axes.
As an alternative embodiment, the deflection frame 61 can be locked by a locking assembly 63 mounted on the deflection guide plate 62. When the angle of the deflecting frame 61 is deflected to the right position and no adjustment is needed for a short period of time or after the completion of the work, the deflecting frame 61 may be locked using a locking mechanism.
Specifically, the locking assembly 63 may be a worm gear structure formed at a rotation shaft of the deflection frame 61, wherein a worm gear is fixedly provided with a rotation shaft portion of the deflection frame 61. The worm gear structure has a self-locking function, when the worm gear structure is used independently, the worm gear can drive the deflection frame 61 to rotate in a worm rotating mode, and the grinding stone assembly 3 can deflect inwards or outwards at the moment.
Or, as an alternative embodiment, the deflecting unit 6 further includes a driving structure 64 for pushing the deflecting frame 61 to rotate relative to the base 1, and two ends of the driving structure 64 are respectively connected to the deflecting frame 61 and the base 1 for adjusting the angle of the deflecting frame 61 deflecting relative to the base 1. The drive structure 64 may be an electric or hydraulic cylinder.
When the position of the grinding stone assembly 3 is adjusted to be proper, in order to ensure the cutting effect, the grinding stone assembly 3 needs to be adjusted to move downwards until the grinding stone assembly is contacted with a steel rail and generates a certain pressure. This operation is performed by the feeding unit 7. The feeding unit 7 comprises a guide assembly 71 and an actuating assembly 72, the guide assembly 71 can be connected with the grinding unit and the actuating assembly 72, one end of the actuating assembly 72 is fixedly connected with the deflecting frame 61, and the actuating assembly 72 can press the grinding unit under the guidance of the guide assembly 71.
