Description
Technical Field
The utility model relates to a rail maintenance of equipment field, in particular to an eccentric shaft wheel for tread polisher.
Background
With the rapid development of high-speed railway construction and the continuous improvement of high-speed heavy-load indexes in China, the abrasion of steel rails is more and more serious; on the other hand, the long-time driving causes fatigue pitting on the surface of the steel rail and irregular deformation of the cambered surface part; in order to improve the safety of high-speed rail operation, the tread of the steel rail needs to be maintained regularly. The tread grinding machine is a device specially used for grinding and maintaining the tread of the steel rail. Because the quality of tread polisher is great, for buffer pressure, generally set up four arbor wheels, but because a plane is confirmed to three points, this just makes the fourth arbor wheel unsettled easily, leads to the gravity of polisher to press on three arbor wheel, very easily increases the wearing and tearing of arbor wheel, influences the life of arbor wheel, only supports by three arbor wheel moreover, can cause the polisher to rock for stability descends.
It is therefore necessary to provide an eccentric wheel for a tread grinding machine to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an eccentric shaft wheel for tread polisher can effectual adjustment height for four shaft wheels can remain on a plane all the time, make four shaft can both support the polisher, reduce the degree of wear of shaft wheel, improve the life of shaft wheel, can improve the stability of polisher moreover.
The utility model provides a technical scheme that its technical problem adopted is: an eccentric shaft wheel for a tread grinding machine comprises a support frame, a rotating shaft and an adjusting assembly connected with the rotating shaft, wherein the support frame comprises a supporting part and a fixing part, a through hole is formed in the supporting part, and the adjusting assembly is arranged on the supporting part;
the adjusting part comprises a rotating block and a connecting column fixed with the rotating block, the connecting column is arranged in the supporting part, the rotating shaft is fixed with the connecting column, the rotating shaft and the connecting column are cylinders, the axis of the rotating shaft is parallel to the axis of the connecting column, and the outer diameter of the rotating shaft is smaller than the outer diameter of the connecting column.
Specifically, the fixing part is provided with a plurality of fixing positions.
Specifically, a limiting plate is arranged on the connecting column.
Specifically, be equipped with drive assembly in the pivot, drive assembly includes the sleeve pipe, is used for adjusting sheathed tube bolt, cover to establish pivot a plurality of bearings, the inner wall and the pivot of bearing are fixed, the outer wall and the sheathed tube inner wall of bearing support and lean on.
Specifically, a baffle is arranged on one side of the sleeve close to the supporting part.
The utility model relates to an eccentric shaft wheel for tread polisher's beneficial effect is, through rotating assembly, height that can effectual regulation pivot for four arbor wheels can remain on a plane all the time, make four shaft can both support the polisher, reduce the degree of wear of arbor wheel, improve the life of arbor wheel, four shaft all contact with the rail in addition, can avoid the polisher to take place to rock at removal or during operation, improved the stability of polisher.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic view of the eccentric wheel for a tread sander according to the present invention;
FIG. 2 is a schematic view of the eccentric wheel for the tread sander according to the present invention;
FIG. 3 is a schematic view of the adjusting assembly for a tread sander according to the present invention;
in the figure: 11. the bearing comprises a supporting part, 12 parts of a fixing part, 2 parts of a sleeve, 3 parts of a baffle, 4 parts of a rotating block, 5 parts of bolts, 6 parts of a rotating shaft, 7 parts of a bearing, 8 parts of a connecting column and 9 parts of a limiting plate.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, an eccentric shaft wheel for a tread grinding machine comprises a support frame, a rotating shaft 6 and an adjusting assembly connected with the rotating shaft 6, wherein the support frame comprises a supporting part 11 and a fixing part 12, a through hole is arranged on the supporting part 11, and the adjusting assembly is arranged on the supporting part 11;
as shown in fig. 3, the adjusting assembly includes a rotating block 4 and a connecting column 8 fixed to the rotating block 4, the connecting column 8 is disposed in the supporting portion 11, the rotating shaft 6 is fixed to the connecting column 8, the rotating shaft 6 and the connecting column 8 are both cylinders, the axis of the rotating shaft 6 is parallel to the axis of the connecting column 8, and the outer diameter of the rotating shaft 6 is smaller than the outer diameter of the connecting column 8.
Specifically, the fixing portion 12 is provided with a plurality of fixing positions. The fixed position can be fixed with the polisher frame through the set screw and remove, the dismouting of arbor wheel of being convenient for.
Specifically, a limiting plate 9 is arranged on the connecting column 8. The limiting plate 9 can prevent the connecting column 8 and the rotating shaft 6 from changing angles, so that the rotating shaft 6 can be kept horizontal.
Specifically, be equipped with drive assembly on pivot 6, drive assembly includes sleeve pipe 2, is used for adjusting 2 bolt 5, the cover of sleeve pipe to establish a plurality of bearings 7 in pivot 6, the inner wall and the pivot 6 of bearing 7 are fixed, the outer wall of bearing 7 supports with sleeve pipe 2's inner wall and leans on.
Specifically, a baffle 3 is arranged on one side of the sleeve 2 close to the supporting part 11. The shield 3 prevents the sleeve 2 from being removed from the rail during rotation.
The working principle of the eccentric shaft wheel for the tread grinding machine is as follows: the workman places the polisher on the rail for three arbor wheel supports with the rail and leans on, and the turning block 4 that the workman's operation can adjust the fourth arbor wheel this moment rotates, because pivot 6 and spliced pole 8 are not coaxial setting, and pivot 6 can rotate round spliced pole 8's center, realizes the fine setting of height, thereby makes the fourth arbor wheel also can contact the rail.
Compared with the prior art, this an eccentric arbor wheel for tread polisher, through rotating assembly, height that can effectual regulation pivot 6 for four arbor wheels can remain on a plane all the time, make four shaft can both support the polisher, reduce the degree of wear of arbor wheel, improve the life of arbor wheel, four shaft all contact with the rail in addition, can avoid the polisher to take place to rock at removal or during operation, improved the stability of polisher.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
