Technical Field

The present invention relates to a rail grinding machine for grinding a rail of a track according to the preamble of claim 1.

Background

DE 202017000696U 1 discloses a rail grinding machine, the grinding unit of which is flexibly adjustable. For this purpose, the sander has a transverse slide movably mounted on a frame. Fixed to the transverse slide is a middle frame on which a motor frame is mounted, which is mounted vertically adjustable and pivotable about a vertical axis. The sharpening unit is in turn pivotally mounted on the motor frame.

Disclosure of Invention

The object underlying the present invention is to provide a rail grinding machine which is structurally simple and robust and which enables the grinding unit to be flexibly adjusted.

The above object is achieved by a rail grinding machine having the features of claim 1. Since the transverse slide comprises a closed transverse slide frame, the transverse slide is made extremely stable, so that the sanding unit can be flexibly adjusted and arranged stably on the transverse slide in a simple manner. In particular, the lateral slider frame forms a closed annular body which is more stable than the U-shaped bodies known in the prior art. The lateral slide frame extends in a longitudinal direction and a lateral direction. By means of the closed cross slide frame, the cross slide is simply used for arranging the flexibly adjustable sanding unit.

The transverse slide frame extends in a longitudinal direction which corresponds to the direction of movement of the rail grinding machine and is also referred to below as the x-direction. In addition, the closed transverse slider frame extends in a transverse direction, which is perpendicular to the longitudinal direction and is also referred to below as the y-direction. The vertical direction perpendicular to the longitudinal direction and the transverse direction is hereinafter also referred to as z-direction. The x, y and z directions form a cartesian coordinate system.

A machine for grinding rails as claimed in claim 2, which is structurally simple and robust. The closed transverse slider frame is formed in a simple manner by the transverse members and the longitudinal members. The cross members extend in a transverse direction and are spaced apart in a longitudinal direction. In particular, the cross members extend parallel to each other. The longitudinal members interconnect the cross members. The longitudinal members extend in a longitudinal direction and are spaced apart in a transverse direction. In particular, the longitudinal members extend parallel to each other. Preferably, the cross members and the longitudinal members are interconnected at the ends, thus giving the closed cross slide frame a rectangular shape in top view.

A rail grinding machine according to claim 3, which ensures a simple and robust construction and a flexible and adjustable grinding unit. The lateral slider includes a first lateral-slider guide roller that is arranged above a second lateral-slider guide roller when viewed in the vertical direction. The first lateral slide guide roller is disposed at an upper side of the frame, and the second lateral slide guide roller is disposed at a lower side of the frame. Thus, the frame extends between the first and second lateral-slide guide rollers when viewed in the vertical direction. At least two first and at least one second cross-slide guide rollers are arranged, for example, on each cross member of the cross-slide frame to ensure that the cross-slide is guided on the machine frame accurately and in a stable manner or without play. In particular, the cross-slide guide roller is of self-centering design, so that it is centered or aligned on itself on the machine frame by its cross-sectional shape. In order to move the transverse slide in the transverse direction, the rail grinding machine preferably has a transverse-slide spindle drive which can be actuated manually, for example.

A rail grinding machine according to claim 4, which ensures a simple and robust construction and a flexible and adjustable grinding unit. The guide frame allows the sanding unit to be arranged in a simple manner such that it is linearly adjustable in the vertical direction and/or pivotable about a pivot axis. Preferably, the guide frame is pivotally mounted on the lateral slide. In particular, the guide frame is arranged on the closed cross slide frame, which therefore additionally reinforces the cross slide frame.

A rail grinding machine according to claim 5 which ensures that the grinding unit is flexibly adjustable. By means of said pivot axis extending parallel to the longitudinal direction, the rail can be ground sideways. Preferably, the guide frame is pivotable about the pivot axis by at least 60 degrees, in particular by at least 90 degrees and in particular by at least 120 degrees. Preferably, the guide frame is mounted on the closed lateral slider frame by means of two pivoting supports. For this purpose, the guide frame has, for example, two guide posts which are pivotably mounted on the closed transverse slider frame. In particular, the guide frame can be pivoted about the pivot axis by means of a guide frame drive. The guide frame drive can be actuated manually, for example. The guide frame drive comprises, for example, a spindle drive or a rack drive.

A rail grinding machine according to claim 6, which ensures a simple and robust construction and a flexible and adjustable grinding unit. Preferably, the guide post and the connecting member connecting the guide posts form a U-shape. The guide posts are arranged on the closed transverse slider frame, in particular at the ends. Preferably, the guide post is pivotally attached to the cross member. The guide posts extend parallel to each other and are capable of linearly adjusting the arrangement of the sharpening unit. The connecting member connects and stabilizes the guide post. In particular, a grinding unit spindle drive for linearly moving the grinding unit in a vertical direction is fixed to the connecting member. The grinding unit spindle drive can be actuated manually, for example. The connecting member connects the guiding studs at the end of the guiding frame remote from the transverse slide, thus ensuring that the sharpening unit arranged on the guiding frame is free to access the rails.

A rail grinding machine according to claim 7 which ensures that the grinding unit is flexibly adjustable. Preferably, the sharpening unit is mounted on both sides of the guide frame, in particular by means of sharpening unit supports. Preferably, the guide frame is pivotally mounted on the transverse slide frame, thereby enabling the sharpening unit to move linearly in a vertical direction and to pivot about a pivot axis.

A machine for grinding rails as claimed in claim 8, which is structurally simple and robust. The sanding unit support is movably arranged on the guide frame and stabilizes the guide frame in a simple manner. Preferably, the sharpening unit support has two support columns which are guided on both sides of the guide frame, in particular on associated guide columns. Preferably, the sharpening unit support has fixing means, thereby enabling the sharpening unit to be fixed in a desired sharpening position with respect to the guide frame.

A rail grinding machine according to claim 9, which ensures a simple and robust construction. Since the sharpening unit support comprises a closed support frame, the sharpening unit can be fixed in a simple and stable manner and the guide frame can be additionally stabilized. The support frame comprises two support columns extending substantially in a vertical direction and movably mounted on the guide column. Preferably, the support column is of tubular design, thus ensuring that the support column is guided on the guide column in a simple and reliable manner. To this end, the guide posts each extend through one of the support posts. The support columns are interconnected by longitudinal members. The longitudinal members extend generally in a longitudinal direction and are arranged at a spacing in a vertical direction. The longitudinal member is connected to the support post generally at an end. The sharpening unit is fixed to the first longitudinal member closer to the lateral slide. The sharpening unit is arranged in a fixed manner (i.e. in an immovable manner) relative to the sharpening unit support. In particular, a sharpening unit spindle drive for moving the sharpening unit support in a vertical direction is fixed on the second longitudinal member further from the transverse slide. The closed support frame defines an interior space in which a drive motor of the sharpening unit is at least partially disposed.

A rail grinding machine according to claim 10, which ensures a simple and robust construction and a flexible and adjustable grinding unit. Since the sharpening unit support is movably mounted on the guide post, the guide frame and the sharpening unit support are stable. The transverse slide, the guide frame and the sharpening unit support enable the sharpening unit to be adjusted in a simple and flexible manner to machine the respective rail.

Detailed Description

The rail grinding machine 1 is for grinding one rail 2 of a track, respectively, and has a frame 3, and the frame 3 is guided on the rail 2 by guide rollers 4. The frame 3 is supported on the other rail 2 of the track via guide rollers 4 by means of projecting brackets 5. A handle 6 is arranged on the frame 3, by means of which handle 6 the grinding machine 1 can be manually moved on the rail 2. The guide roller 4 defines the direction of movement of the sanding machine 1, which is also referred to below as the longitudinal direction or x-direction.

The frame 3 has frame longitudinal members 7, 8 and frame cross members 9, 10 connected to each other, so that the frame 3 has a closed shape. The frame longitudinal members 7, 8 extend in the x-direction and are spaced apart in the y-direction perpendicular to the x-direction. The y-direction is also referred to as the transverse direction below. The frame cross members 9, 10 extend in the y-direction and are spaced apart in the x-direction. The frame cross members 9, 10 are fixed at the ends to the frame longitudinal members 7, 8, so that the frame 3 is rectangular in shape. The outriggers 5 are arranged in the frame cross members 9, 10 in a manner allowing telescopic movement, so that the guide rollers 4 are variably spaced apart in the y-direction.

The transverse slide 11 is mounted on the frame 3. The transverse slide 11 can be moved in the y-direction relative to the machine frame 3 by means of a transverse slide spindle drive 12. The cross slide 11 has a closed cross slide frame 13, which cross slide frame 13 is formed by longitudinal members 14, 15 and cross members 16, 17. The longitudinal members 14, 15 extend in the x-direction and are spaced apart in the y-direction. The longitudinal members 14, 15 are interconnected at the ends by means of cross members 16, 17, so that the cross slide frame 13 is rectangular in shape in top view. The cross members 16, 17 extend in the y-direction and are spaced apart in the x-direction.

The cross members 16, 17 comprise a first portion 18 and a second portion 19, respectively. The first portion 18 interconnects the longitudinal members 14, 15; the second portions 19 extend generally centrally downwardly from the respective first portions 18 when viewed in a vertical direction. The vertical direction is also referred to as z-direction hereinafter, and is perpendicular to the x-direction and the y-direction. Thus, the x, y and z directions form a cartesian coordinate system.

First transverse-slide guide rollers 20 are rotatably mounted on the respective transverse member 16, 17, on the respective first portion 18 and on either side of the associated second portion 19. In addition, second cross-slide guide rollers 21 are rotatably mounted on the respective cross members 16, 17 and on the respective second portions 19. The first transverse-slide guide roller 20 is mounted at a distance from the second transverse-slide guide roller 21 in the z-direction, so that the first transverse-slide guide roller 20 is arranged on the upper side of the machine frame 3 and the second transverse-slide guide roller 21 is arranged on the lower side of the machine frame 3. The transverse slide guide rollers 20, 21 have a self-centering cross-sectional shape and thus guide the transverse slide 11 in a self-centering manner on the frame 3.

A transverse slide spindle drive 12 is fixed on the transverse slide 11 and on the frame 3 and can be actuated manually by means of a hand wheel 22, thus enabling the transverse slide 11 to be moved in the y-direction.

A guide frame 23 is mounted on the transverse slide 11 such that the guide frame 23 can pivot about a pivot axis 24. The guide frame 23 includes two guide posts 25, 26 and a connecting member 27 connecting the guide posts 25, 26. The guide posts 25, 26 are arranged at the ends on one of the second portions 19 of the cross members 16, 17, respectively. For this purpose, the guide posts 25, 26 are connected to the transverse slide frame 13 by means of respective pivot supports 28, 29. The pivot supports 28, 29 comprise pivot pins which extend from the second portion 19 through associated holes in the guide posts 25, 26 and thus form the pivot axis 24. The pivot axis 24 extends parallel to the x-direction. The closed lateral slide frame 13 defines an inner space for mounting the guide frame 23 when viewed in plan view.

The guide posts 25, 26 extend parallel to each other and are connected at the end opposite the pivot axis 24 by means of a connecting member 27. Thus, the guide frame 23 has a U-shape. For pivoting the guide frame 23, the sander 1 has a guide frame drive 30. The guide frame drive 30 is fixed on the guide frame 23 of the transverse slide 11 and can be actuated manually by means of a hand wheel 31. The guide frame 23 is pivotable relative to the transverse slide 11 about the pivot axis 24 by at least 60 degrees, in particular by at least 90 degrees and in particular by at least 120 degrees.

The sander 1 has a sanding unit 32, the sanding unit 32 being mounted on the guide frame 23 by means of a sanding unit support 33. Thus, the sharpening unit 32 can be moved in the y-direction by means of the transverse slide 11 and can be pivoted about the pivot axis 24 by means of the guide frame 23. The sharpening unit support 33 is arranged on the guide frame 23 to be pivotable in the z direction. The sharpening unit support 33 comprises a closed support frame 34. The support frame 34 is composed of support columns 35, 36 and longitudinal members 37, 38 connecting the support columns. The support columns 35, 36 are of tubular design. The guide posts 25, 26 each extend through one of the support posts 35, 36, so that the support posts 35, 36 are movably guided on the guide posts 25, 26. The support columns 35, 36 are connected at the ends by longitudinal members 37, 38, so that the support frame 34 forms a closed shape. The longitudinal members 37, 38 extend in the x-direction and are spaced apart in the z-direction. The sharpening unit 32 is fixed in a fixed manner (i.e. without the ability to move) on the first longitudinal member 37, which is closer to the transverse slide 11. For moving the support frame 34, the sander 1 has a sanding unit spindle drive 39, which sanding unit spindle drive 39 is fixed to the connecting member 27 and the second longitudinal member 38, which is further from the transverse slide 11. The sharpening unit spindle drive 39 can be actuated manually by means of a hand wheel 40.

The sanding unit 32 has a drive motor 41 and a sanding tool 42, the sanding tool 42 being rotatably drivable about a rotational axis 43 by means of the drive motor 41. When viewed in the z direction, the sanding tool 42 is arranged below the longitudinal member 37 and the drive motor 41 is arranged above the longitudinal member 37. The drive motor 41 extends at least partially into the interior space defined by the support frame 34.

By means of the closed frame 3, the closed transverse slide frame 13 and the closed support frame 34, the sander 1 can be made structurally simple and robust. By means of the linearly movable transverse slide 11, the pivotable guide frame 23 and the linearly movable grinding unit support 33 or support frame 34, the grinding unit 32 can be flexibly adjusted for grinding the rail 2.
